The recent outbreak of the coronavirus has shown us that our global health system is only as strong as its weakest link.

The key to stemming the spread of such illnesses lies in bolstering connectivity and communication between health bodies and thats precisely the theme here at Arab Health 2020.

Artificial intelligence means medical bodies can link up their data and act quickly in a crisis.

"As emergency physicians and practitioners were often on the frontline. But Ill give you an example of how technology and AI may help outbreaks, not just Coronavirus, but for seasonal influenza," says Dr Jacques Kobersy, emergency medicine institute chair, Cleveland Hospital Abu Dhabi.

"When you have an organisation like WHO who are alerted to the fact that there is some new virus circulating, Artificial intelligence might give us the opportunity to flag that those unusual symptoms are occurring way before human clinicians and departments of health realize it. And help us get ahead of these sort of pandemics maybe a month or so ahead of time before they really fester."

55,000 attendees from 159 countries have touched down in Dubai to showcase and learn about the life-changing and groundbreaking technologies poised to transform healthcare as we know it.

Autonomous ambulances

Soon, AI could make autonomous ambulances that automatically arrive at a patients house as soon as somethings wrong.

"We call it a smart ambulance. The high-risk patient, they will start to wear wearable devices. Let's say something happened to that patient. These devices will start to send all the vital data to the system and the hospital. So the physician, he can monitor all the data and monitor the patient 24 hour," says Dr Rashid al Hashimi - youth council member, UAE ministry of health (mohap).

In the future, the ambulance will be auto-drive. So it will go directly to the patient. While they are moving all these signals will be green for them.

When the patient enters the ambulance, there will be some high-resolution cameras. They will detect the patient's face and will give all the data which is very important for the rescuers to help the patient.

While they are going to the hospital, there will be like a virtual doctor inside the ambulance.

AI implants

AI is already powering implants that can monitor patients vitals around the clock.

"We can put devices under the skin and telemonitor heart patients even at home. We have put this device on 30 patients," says Dr Noor al Muhairi, head of medical services, hospital dept (mohap).

"One of them was in London. And we saw that we have an abnormality in his heart. And we called them directly and told him, go to the nearest hospital and this saved him."

And unprecedented advancements in stem-cell research mean damaged heart cells can now be regrown.

"In treatment, we collaborated with Osaka University, where they have done a study on stem cells that have been generated to cardiac cells. You can bring stem cells to make the heart cells regenerate," says Dr Muhairi.

"So this is one of the latest technology in heart treatment and in collaboration with Japan, we are going to do a clinical study here in the Ministry of Health."

Analysing wounds

Meanwhile, image analysis of wounds using machine learning can now prevent amputations caused by diseases like diabetes.

"This machine is checking the healing process for the diabetic foot. It will give us the results within 30 seconds. We are just scanning for the wound.2

"There is information going back 15 years in this machine. So it will check with other types of wound and it will analyze for us exactly the problem. We can prevent amputations from the complication of diabetes," says Dr Halima el Shehhi, the emergency department unit manager at the ministry of health and prevention, UAE.

Whether it's artificial intelligence, new equipment, new abilities to analyze patients and treat them, things that we could only imagine a few years ago now have come to fruition.

Soon the days of treating illnesses after they occur will give way to an age of truly preventative healthcare.

AESTHETICS medicine encompasses non-invasive treatments that do not involve surgery and aim to improve or correct the appearance of patients. Less intensive than cosmetic surgery, aesthetics medicine procedures are carried out by doctors to give natural and reversible results. Depending on your areas of concern, different techniques may be employed in combination to produce the best results - there is no "cookie-cutter" approach to your skincare needs.

Our skin has three layers:

The epidermis, the outermost layer of skin, provides a waterproof barrier to protect our body from germs and harmful UV rays. Its bottom-most layer makes new skin cells, and these skin cells travel up to the top layer and flake off, about a month after they form. It also gives you your skin colour, due to the presence of special cells called melanocytes, which produce the pigment melanin.

The dermis, the middle layer, contains tough connective tissue, blood vessels, hair follicles, and sweat glands.

The hypodermis, the innermost layer, is made of fat and connective tissue.

Ageing happens in every layer of the skin. Changes within the skin's layers show themselves on the surface as signs of ageing.

In the epidermis, a slower cell turnover and reduction in lipid production on the skin's surface means rough and dry skin as we age. Our skin is less efficient at repairing itself from harmful infections and UV rays. This causes pigmentation problems, like sunspots.

In the dermis, from the age of 25, there is a 1 per cent annual decrease in collagen, one of the "building blocks" of the skin. Elastin also decreases as we age. Hence, the structure of the skin is compromised, and wrinkles and saggy skin start to appear.

In the deeper layers, the hypodermis, the changes to the size and number of fat cells leads to deep wrinkles and hollow cheeks.

Skin ageing manifests by:

Fine lines and wrinkles: The first noticeable sign of ageing from 25 onwards are fine lines and wrinkles, especially around your eyes. Your dermis, the second layer of your skin, contains the collagen and elastic fibres that keep young skin plump, taut and wrinkle-free. The amount of collagen and elastic fibres in your dermis dwindles as the years roll on. As a result, your skin becomes less elastic, sags and you start to see the tell-tale signs of wrinkles.

Open pores and sagging skin: Ageing causes your skin to lose its elasticity, which stretches your pores and make them look larger. The accumulation of excess oil, dead skin cells and dirt trapped inside your pores also enhances their appearance. Hormonal changes such as pregnancy, menstruation and puberty can also enlarge your pores.

Dry and dull skin: Your epidermis forms the outer layer of your skin - a physical barrier from the external environment. On average, your body will produce an entirely new epidermis about every 60 days. Cells on the surface of your skin rub and flake off, continuously being replaced with new ones from below.

As you get older, it takes longer for your epidermis to renew itself, hence, more dead skin cells accumulate on the top layer of our skin. This diffuses light away and produces a dull skin tone. In addition, as we age, oil production slows down and this makes our skin dry - we soon lose that "Korean glass-skin effect".

Hyperpigmentation

Melanocytes located in the epidermis produce pigment called melanin. Hyperpigmentation is caused by an overproduction of melanin in patches of the skin.

This overproduction is triggered by a variety of factors, including sun exposure, genetic factors, age, hormonal influences, and skin injuries or inflammation.

Common types of hyperpigmentation encountered in our population are:

Melasma: Melasma is a common skin problem among Asians. Women are far more likely than men to get melasma, especially during pregnancy. They present as brown to gray-brown patches, usually on the face. Most people get it on their cheeks, nose bridge, forehead, chin, and above their upper lip. It also can appear on other parts of the body that are exposed to sunlight, such as the forearms and neck.

Solar lentigo: Solar lentigo, also known as age spots, are non-cancerous lesions that occur on the sun-exposed areas of the body. These flat lesions usually have well-defined borders, are dark in colour, and have an irregular shape. The backs of hands and face are common areas.

The lesions tend to increase in number with age, making them common among the middle age and older population. Age spots occur in 50 per cent of women and 20 per cent of men over the age of 50, due to stimulation from UV rays.

Post-inflammatory hyperpigmentation (PIH): It is temporary pigmentation that follows injury, for example, a cut to the skin, or inflammation of the skin, for example, acne or eczema. PIH can occur in anyone, but is more common in darker-skinned individuals, in whom the colour tends to be more intense and persist for a longer period than in lighter skin.

Freckles: Freckles are common, especially among fairer-skinned individuals. They start early on in life, even in childhood, and are due to your genetic makeup and sun exposure.

Dull skin, enlarged pores, pigmentation - How can they be corrected?

Avoid sun exposure: Sun exposure is the main cause of ageing. Choose a sunscreen with "broad spectrum" protection, meaning that it protects against both UVA and UVB rays. UVA rays also contribute to skin cancer and premature aging, UVB rays are the main cause of sunburn and skin cancers.

Ensure your sunscreen has a SPF30 or higher. Physical sunscreen, those that contain zinc oxide or titanium dioxide, provide better sun protection compared to chemical sunscreens, and are less likely to clog pores and cause pimples.

Protect your eyes with sunglasses and cover up with a wide-brimmed hat or an umbrella. Limit your direct exposure to the sun, especially between 10am and 4pm, when UV rays are strongest. Avoid tanning beds, which can cause serious long-term skin damage and contribute to skin cancer.

Lightening creams: Abnormal accumulation of melanin results in hyperpigmentation. Lightening creams contain ingredients to reduce the production of melanin. Powerful lightening creams are available through a prescription from a doctor, while milder ingredients do not require a prescription.

Hydroquinone is a major ingredient in lightening creams. However, frequent adverse reactions experienced by patients, such as skin irritation and inflammation, have prompted research into other agents. Several alternatives such as tranexamic acid, and 4-n-butyl resorcinol, arbutin and kojic acid have been developed.

Lasers: There are many different lasers in the market, for many different types of indications. The property of the laser, which determines what it is used for, is the specific wavelength it emits. Different structures in the skin will absorb light energy at different wavelengths. Therefore, in pigmentation treatments, we can deliver light energy at the correct wavelength to heat up the pigmentation, while sparing the other nearby structures that absorb different wavelengths.

The pigmentation absorbs the light energy and is broken up into small fragments and eventually is cleared from the skin.

My personal favourite protocol is to use two very effective lasers for pigmentation treatment, via a Rejuvenation Laser protocol.

The Nd:YAG laser emits wavelengths of 1064nm and 532nm. It is a gentle cleansing machine that helps to remove surface dirt and oil, cleanse your skin, dry up pimples, build collagen and is very effective to break up pigmentation into small fragments.

The yellow laser, made in Germany, emits a wavelength of 577nm. It helps with improving radiance, giving you radiant skin, reducing redness and effectively vaporising pigmentation.

The Rejuvenation Laser is non-ablative, gentle and has no downtime.

Combined with a potent post-procedure serum, it synergistically enhances the anti-ageing effect of the laser protocol. The serum employs proteins secreted by umbilical cord-lining stem cells to produce collagen, restore healthy skin function and treat symptoms of ageing.

Aesthetic treatments can help you maintain your youthful glow - The Business Times

Skin Stem Cells Comments Off on Aesthetic treatments can help you maintain your youthful glow – The Business Times | February 7th, 2020

Do you ever wonder why celebrities are never seen with dark circles under their eyes? Well, we discovered the secret behind the flawless complexions of the rich and famous and its something you can use at home.

After we were especially impressed by the performance of Cardi Bs enviable complexion on the red carpet ahead of the Grammy Awards a few weeks ago, we investigated her skincare routine. As it turns out, this pop stars go-to treatments are Lancer Method 3-step regimen and Dr. Lancers Eye Lifting Cream for an extra boost under the eyes.

These impressive at-home skincare products are designed to promote a youthful appearance in the skin by supporting collagen regeneration and speeding up cell turnover. The result is skin that looks and feels younger, in a natural way.

Lancer The Method: Normal-Combination Set ($255)

Everything You Need To Know About The Lancer Method

The Lancer Method works in three steps used once a day to give you glowing, rejuvenated skin. Dr. Harold Lancer explained to SheFinds, The Lancer Method was developed to help skin act younger by accelerating cell turnover, supporting natural collagen regeneration, and feeding skin essential nutrients. Polish is a dual-action exfoliator that improves the look of fine lines, texture, discoloration and pores for a smoother, younger-looking complexion.

The hydrating, pH-balanced cleanser comes next and gently removes makeup, dirt and oil for a fresh, healthy-looking complexion. Nourish is an ultra-hydrating moisturizer that reduces the look of fine lines and wrinkles while delivering essential nutrients for a dewy and glowing appearance.

Lancer Eye Contour Lifting Cream ($95)

What The Dr. Lancer Eye Lifting Cream Does

Even with the best daily anti-aging skincare routine, we all need to give a little extra love to the skin under our eyes from time to time. This skin is extra sensitive and therefore, more prone to the effects of stress and environmental damage. Dr. Lancers Eye Lifting Cream specifically targets this area to brighten and smooth the skin to reduce the appearance of aging.

Eye Contour Lifting Cream is a triple-action eye treatment and hydrator that targets multiple eye are concerns for a brighter, more youthful experience, Dr. Lancer said. Its proprietary complexes work to improve the appearance of fine lines, wrinkles, puffiness, dark circles and loss of elasticity. When used together, this powerful combination of products targets all areas of the face and top skincare concerns, leaving you with a clear and youthful complexion.

Dr. Lancer said that the best way to promote a youthful glow in your skin is to use hyaluronic acid, peptides, vitamins A, C and E and bioactive phytocompounds.

Hyaluronic Acid is a component of connective tissues that cushions and hydrates. Hyaluronic Acid is found in the skin naturally, but decreases with age so it is important to replenish it topically in conjunction with other ingredients to treat wrinkled skin, Dr. Lancer explained. Peptides are short snippets of linked amino acids reduce the appearance of wrinkles and fine lines as they stimulate collagen production. Vitamins A, C and E are antioxidants that prevent free radical damage and combat oxidation.

And bioactive phytocompounds have been isolated from natural plant sources- some examples: natural fruit enzymes, moisturizing ingredients such as sea algae and aloe vera, grape polyphenol, lilac stem cells, skin lighteners from licorice root, anti-inflammatory agents from ginger root, natural tea tree oil, chamomile oil and marula oil.

Its no secret that loading your plate with fruits and vegetables and eschewing processed meat products is good for your insides. But is a vegan diet good for healthy skin, too?

Many celebrities say that it is; Natalie Portman and Billie Eilish have noticed significant improvements in their skin since going vegan and cutting out dairy.

Portman told the Cut a few years ago, Im vegan and I found my skin is much, much better than when I was a vegetarian. I cut out dairy and eggs, and I never had a breakout after. Eilishwho went vegan for ethical reasonssaid in a Tumblr post in 2018, Im lactose intolerant and dairy is horrible for your skin and my skin is VERY aware of that.

But its not just celebrities who think veganism is good for your skin, experts agree that theyre onto something. Blade Tiessena medical aestheticianwho owns the Ontario-based Anti-Aging Clinic and has worked in skincare for 33 yearsbelieves that ditching animal products for a healthy vegan diet can have a dramatic effect.I say this from both personal and professional experience. I suffered from acne since my early teens until months after going vegan at 35, being in the industry I had every treatment and product at my disposal over the years, he told LIVEKINDLY. Some helped to keep breakouts under control but nothing solved the issue permanently until shortly after becoming vegan.

Multiple studies say that ditching dairy could help acne-sufferers. Acne is the most common skin condition in the United States; it affects around 50 million Americans every year.

There are a few different theories on why dairy can cause an acne flare-up; some studies suggest that hormones in cows milk are the culprit. These hormones are intended to stimulate growth in calves. When humans ingest them, they release insulin, which can trigger breakouts.

According to a medically-reviewed article on Healthline, sometimes the hormones in milk can also interact with our own hormones, confusing our bodys endocrine system and signaling breakouts.

Nonprofit PlantPure Communities (PPC) recently launched a social media campaign called Ditch Dairy for Clearer Skin. The campaign aims to educate the public about the link between acne and dairy consumption.

In a supporting article, pediatrician Dr. Jackie Busse, MD, FAAP, says, removing dairy is the first and most important dietary change you should make to prevent and treat acne.

A vegan diet could also help people who suffer from eczemaa condition where patches of skin become inflamed, itchy, and cracked. According to Healthline, a handful have studies have shown that a raw, vegan diet, in particular, can be very beneficial, although there isnt conclusive evidence.

Plant-based foods have also been linked with easing psoriasis, an immune-mediated disease. Similar to eczema, it causes raised red flaky patches to appear on the skin.

Eating a whole food plant-based diet can help psoriasis sufferers because it is naturally low in inflammatory foods, says dietician Deirdre Earls, RD, LD. She was once hospitalized with psoriasis as a child, but switching to a plant-based diet helped her manage the condition effectively.

She told Everyday Health,I drastically changed my diet. I took all of the diet coke, all of the ultra-processed stuff out, and then I replaced it with simple, whole, mostly plant-based foods. Within six months, my skin had cleared.She added,psoriasis is an inflammatory condition, so anything you can do to cut down on inflammation should help.

Reality TV personality and entrepreneur Kim Kardashian-West has suffered from psoriasis for more than a decade and was recently diagnosed with psoriatic arthritis. She opened up on sister Kourtney Kardashians website Poosh about her battle with the disease, and how switching to a plant-based diet has helped her.

I love a healthy life and try to eat as plant-based as possible and drink sea moss smoothies,she said, adding that she also tries to keep her stress levels to a minimum.I hope my story can help anyone else with an autoimmune disease feel confident that there is light at the end of the tunnel.

Eating vegan foods can help with painful conditions, but they can also just make your skin glow too.

According to Tiessen, patients who follow a vegan diet achieve superior skin results to those who do not. They also have more energy and they sleep better. He says, eating a healthy vegan diet free of inflammatory foods along with drinking lots of water, sleeping well, exercising, reducing levels of stress, taking care of and protecting your skin will help ensure beautiful glowing skin that will last a lifetime.

He also recommends using cruelty-free vegan skincare products. Skincare should be looked at as nutrition and protection for the skin, he added. Supplying the skin with nutrients from organic plants can offer benefits that are unavailable from chemicals and or animal-based ingredients.

If you want to opt for cosmetic intervention, Tiessens clinicsin Orillia Ontario and Port Severn Ontariooffer many cruelty-free and vegan treatments, including microneedling. The chain is also an ambassador for vegan medical skincare brand ElaSpa.

If you prefer to stick to just consuming whole foods, here are seven of the best plant-based foods to eat to keep your skin looking glowing and healthy.

Eating spinach regularly can benefit your skin. Its rich in vitamins and minerals, including vitamin A, vitamin C, and vitamin E, which are particularly good for your skin. Its also a great source of iron, as well as folate and magnesium.

Blueberries are packed with skin-beautifying antioxidants. Stephanie Clarkeco-owner of C&J Nutritiontold Self, that deep blue/purple color that makes blueberries so gorgeous translates to helping your skin look young too. This color is a result of compounds called anthocyanins, powerful antioxidants that shield the skin against harmful free radicals that can damage the collagen that keeps your skin firm.

Eating avocados is good for your skin, as theyre rich in vitamins C and E. You can also apply them directly to your face and feel their benefits that way. Registered dietician Maureen Eyerman told Elle, the hydrating properties may reduce fine lines and wrinkles, help keep skin smooth, and boost skins immunity against stress and other environmental factors.

Sweet potatoes are rich in vitamin E and vitamin C, which helps to boost collagen. Theyre also rich in anthocyanins, which can help to prevent blemishes and dark spots. Sweet potatoes are also a source of fiber, iron, calcium, and selenium.

Walnuts contain omega-3 fats, which, according to Clarke,strengthen the membranes of your skin cells.They also contain nourishing fats which attract soothing moisture from the air and reduce inflammation, helping to avoid breakouts.

Carrots are associated with good eye health, but theyre good for the skin, too. According to Healthline, vitamin C-rich carrots can help skin recover from conditions like psoriasis and rashes. They can also help you heal faster from cuts and other wounds.

Kiwis have more vitamin C than oranges, and theyre packed with vitamin E. You can also place them over the top of your eyes, which can help to reduce the appearance of dark circles.

The Vegan Diet and Healthy Skin: Everything You Need to Know - LIVEKINDLY

Skin Stem Cells Comments Off on The Vegan Diet and Healthy Skin: Everything You Need to Know – LIVEKINDLY | February 7th, 2020

Looks like some science fiction. Scientists have created what has been described as the first live robots in the laboratory, and they did so by testing different combinations using an "evolutionary algorithm," which can be called electronic evolution.

Before readers begin to imagine androids made of meat, I must point out that these "xenobots" They are less than a millimeter wide and the closest thing they have to the extremities are two stumps that they use to swim through liquids for weeks at a time without requiring additional nutrition. They are composed of embryonic stem cell taken from the African clawed frog, known scientifically as Xenopus laevis, which inspired the name of the tiny bots.

%MINIFYHTMLfbc393bc3889937713c35029ced2f84811%%MINIFYHTMLfbc393bc3889937713c35029ced2f84812%

The scientists used heart cells that act as miniature pistons and skin cells that hold the package together. The level of sophistication involved in this feat of bioengineering suggests that, while the technological glories of the past reside in large monuments and megaprojects, the greatest achievements of the 21st century are found in the microscopic, nano and quantum scales.

Developed by researchers at Tufts University, the University of Vermont and the Harvard Wyss Institute, these impressive miniature biological machines (or should they refer to them as creatures?), Which can repair or heal themselves when they are damaged, They have potentially multiple beneficial uses. .

These include cleaning the microplastics that pollute our oceans and other toxic materials, as well as vectors to administer medications within our bodies, to perform surgical procedures and other medical applications. Unlike conventional robots and machines that can pollute the environment for a long time after their useful lives have expired, xenobots have the additional advantage of being completely biodegradable, which break down harmlessly after "dying."

In addition, such "biological machines,quot; are, in principle, more versatile and robust than their inanimate counterparts. "If living systems could be designed continuously and quickly ab initio and deployed to fulfill novel functions, their innate ability to resist entropy could allow them to far exceed the useful lives of our strongest but static technologies." the researchers postulate.

However, although I do not classify myself as xenobotphobic, I find the possible consequences of biobots and their possible future negative uses quite disturbing, despite the exciting possibilities they present.

Neither the researchers in their scientific paper Outlining the results or news coverage of the xenobots seems to have considered the damaging and destructive potential of this technology. However, this exists and should be carefully considered to avoid the dangerous hazards ahead.

The wrong hands could transform biobots from healing machines to biological weapons. Instead of administering curative medications to the body, they could be used to maim or kill. They could be used to act as the ideal hitmen, committing the perfect murder.

Given the pace of technological progress, the day cannot be very far away when biobots that can send toxins or deadly viruses to the body, attack vulnerabilities in an individual with tailored DNA, simulate a terminal illness or even carry out deadly microsurgery will be developed before a self-destruct mechanism causes them to dissolve in the bloodstream, making these invisible killers impossible to track. They could also be designed and used to attack entire populations, either as acts of biological warfare or bioterrorism.

Even if we manage to control the potential for intentional damage and misuse, there is also the potential for accidental damage. For example, researchers point to the future possibility of equipping biobots with reproductive systems to ensure that they can be (re) produced at scale. However, how can we be sure that they will stick to the script of their programming and produce only the required number of descendants who will live the required useful life?

Do we understand evolution enough to be sure that these novel life forms that we will create will not get rid of the limitations we have designed for them and will mutate in unexpected and potentially risky ways?

Beyond practical applications and erroneous applications, there are long-range ethical dimensions, not to mention the socio-economic and cultural implications for humanity.

By blurring (even more) the lines between the inanimate and the lively, how will we define life in the future? Anything made of organic tissue, no matter how simple and synthetic, continues to be considered life forms, or will we need new categories?

How about the relative value of life / machines? It is a simple xenobot superior to a highly sophisticated synthetic robot, such as Asimo and other expert robots, because one is "alive,quot; and the other probably not.

If intelligence and sensitivity are considered to be some of the characteristics of humanity, will we have to start granting intelligent machines the same rights, since "artificial intelligence,quot; continues to reach and even surpass its human form?

One of the most controversial technological problems of the moment is data privacy rights. But could we reach a point in the future where the data itself needs and has rights? For example, if one day it is considered that robots and computers have become truly intelligent and sensitive, then their data systems will presumably require protection against malicious deletion, which would amount to murder or involuntary modification, which would violate their freedom to choice.

Then there are the existential questions posed by this technological progress. Although technology has rendered the work of countless millions of professions obsolete, in general it has acted as a reinforcement and aid for a humanity in the control of innovation. However, we are rapidly reaching the stage where our technological creations not only eclipse our physical abilities but also our mental abilities and, soon, intellectual abilities.

When we finally build or develop machines that are not only clearly smarter than us, but also have a clear sense of identity and autonomy, we can continue to control them and, if we do, will this be an unjust form of subjugation or even slavery?

To escape the possible inevitability of our own obsolescence and the physical limitations of our bodies, we can decide to merge with our technological creations. We can update or modify our bodies in part or in full, as well as load or update our mental operating systems. Who knows, some may even decide to escape the physical constraints imposed by our mortal and vulnerable bodies, and download their mind and "spirit,quot; into a simulated virtual world (later), transforming into a pure metaphysical code.

Future radical modifications of our physical or mental states, especially if they are divergent among species, will raise the biggest and most fundamental question of all: what does it mean to be human?

Biomedical engineers at Duke University have developed the most advanced disease model for blood vessels to date and used it to discover a unique role of the endothelium in Hutchinson-Gilford Progeria Syndrome. Called progeria for short, the devastating and extremely rare genetic disease causes symptoms resembling accelerated aging in children.

The model is the first to grow both the smooth muscle and inner lining, or endothelium, layers of blood vessels from stem cells derived from the patients own skin. Combined with an advanced experimental setup that pushes culture media that models blood through the engineered blood vessels, the model reveals that the endothelium responds differently to flow and shear stress with progeria than it does when healthy.

The study shows that a diseased endothelium alone is enough to produce symptoms of progeria, and also demonstrates a new way of studying blood vessels in dynamic 3D models to better understand and test treatments for serious diseases.

The results appear online on February 6 in the journal Stem Cell Reports.

The endothelium expresses the toxic protein that causes the symptoms of progeria, but it does so at much lower levels than the outer layer of blood vessels made of smooth muscle, said Nadia Abutaleb, a biomedical engineering PhD student at Duke and co-first author of the paper. Because of this, the entire field has been focused on smooth muscle, and the few that have looked at the endothelium have mostly looked at it in a static 2D culture. But weve discovered that its necessary to work dynamically in three dimensions to see the full effects of the disease.

Progeria is a non-hereditary genetic disease caused by a random single-point mutation in the genome. It is so rare and so deadly that there are only about 250 people known to be currently living with the disease worldwide.

Progeria is triggered by a defect in a protein called progerin that leads it to accumulate outside of a cell's nucleus rather than becoming part of the nuclear structural support system. This causes the nucleus to take on an abnormal shape and inhibits its ability to divide. The resulting symptoms look much like accelerated aging, and affected patients usually die of heart disease brought on by weakened blood vessels before the age of 15.

"Progeria isn't considered hereditary, because nobody lives long enough to pass it on," said George Truskey, the R. Eugene and Susie E. Goodson Professor of Biomedical Engineering at Duke. "Because the disease is so rare, its difficult to get enough patients for clinical trials. We're hoping our platform will provide an alternative way to test the numerous compounds under consideration."

Blood vessels are difficult to simulate because their walls have multiple layers of cells, including the endothelium and the media. The endothelium is the innermost lining of all blood vessels that interacts with circulating blood. The media is made mostly of smooth muscle cells that help control the flow and pressure of the blood.

In 2017, the Truskey laboratory engineered the first 3D platform for testing blood vessels grown from skin cells taken from progeria patients. The blood vessels exhibited many of the symptoms seen in people with the disease and responded similarly to pharmaceuticals.

While the smooth muscle cells in our previous study were created using cells from progeria patients, the endothelial cells were not, said Abutaleb. We suspected that the endothelial cells might be responsible for some of the lingering symptoms in the original study, so we began working to grow blood vessels with both smooth muscle and endothelial cells derived from the same patient.

By successfully growing endothelial cells derived from progeria patients, the researchers were able to create a more complete model of the disease. They also tested the endotheliums unique contribution to the diseases symptoms by mixing impaired endothelium with healthy smooth muscle.

They found that a diseased endothelium alone was enough to produce many of the symptoms of progeria, but that these results only appeared when the cells were tested under dynamic conditions.

One of the major findings is that the progeria endothelium responds to flow and shear stresses differently than healthy endothelium, said Abutaleb.

The new models healthy blood vessels responded to pharmaceuticals more strongly than in past papers, and the diseased blood vessels showed a greater drop in functionality. With this advanced model in hand, the team is now beginning to investigate how new and current drugs for progeria affect a patients blood vessels.

This research was supported by the National Institutes of Health (R01 HL138252-01, UH3TR000505, UH3TR002142) and the National Science Foundation (GRFP Grants #1106401 and DGE1644868).

Engineered Living-Cell Blood Vessel Provides New Insights to Progeria - Duke Today

Skin Stem Cells Comments Off on Engineered Living-Cell Blood Vessel Provides New Insights to Progeria – Duke Today | February 7th, 2020

Imagine a world where those living with Type 1 Diabetes, a chronic illness affecting more than 60 million adults globally, no longer had to deal with regular blood glucose monitoring, daily insulin injections or life-threatening nighttime hypoglycemic events, but instead could eat, exercise and sleep worry-free. Thats the kind of future an up-and-coming breakthrough technology is on track to creating.

Beta-O2 Technologies, a privately held biomedical company headquartered in Israel with research and industry affiliates across the U.S., is working to deliver a first-of-its-kind bio-artificial pancreas as a safe, effective and long-term cure for the disease. With preliminary animal trials showing promising results for its second generation breakthrough device, called Bio-artificial Pancreas (Air), the company is planning to begin human clinical trials within the year.

We have strong pre-clinical evidence to prove the safe operation of our device on animals, said Beta-O2 CEO Amir Lichter, noting that the second generation Air is performing well in ongoing animal studies. Its an enormous achievement that is paving the road for human trials.

Measuring approximately 2.5 by 2.5 inches, Air is made of titanium. It has two components: a macrocapsule that contains pancreatic cells and an oxygen tank equipped with an external port, so patients can easily refresh oxygen levels weekly. Once implanted under a patients skin, it becomes a natural source of insulin, sensing blood glucose levels and delivering insulin as required.

While there are a couple of other artificial pancreatic solutions being explored by different industry players, Beta-O2s disruptive technology is the only bio-artificial pancreas to incorporate an active oxygen supply, necessary to keep the pancreas cells in the implanted device functional and viable over the long term. Other solutions are demonstrating limited success because they rely on a patients bloodstream to deliver enough oxygen to keep the transplanted cells viable, which is problematic, Lichter explained.

Pancreas cells (islets) are extremely delicate, he said. We solve the problem by proactively supplying oxygen through an external source, providing a superior solution.

Lichter said the beauty of the Beta-O2 solution which holds 10 global patents for its exclusive immune protection capabilities and oxygen supply mechanisms is that its very generic, meaning it can contain cells from a human donor, cells from the pancreas of a pig, or cells derived in a lab from stem cells. Other advantages are that Beta-O2s bio-artificial pancreas does not require a patient to take intensive immunosuppression therapies after implant due to its protective encapsulation capabilities, and the device can quickly be retrieved from a patient if necessary due to malfunction or other health concerns, he explained.

Beta-O2 is currently collaborating with several U.S.-based pharmaceutical companies and academics, including researchers from Harvard University, MIT, University of Virginia and Cornell University, to further enhance the Air oxygen supply and its ability to measure glucose levels and secrete insulin once implanted. The company is also in negotiations to solidify its collaboration with several stem cell providers as it looks to secure an additional $15 million in investment funds to support its aggressive go-to-market strategy.

The active oxygen supply used by Beta-O2 is currently the best and most advanced technique for maintaining viability and function of large numbers of pancreaticislets (or stem cell-derived islets) in an encapsulation transplantation device, said Clark K. Colton ofthe Department of Chemical Engineering at MIT andBeta-O2 Scientific Advisory Board member.

Calling the Beta-O2 device a next-gen treatment option, Dr. Jos Oberholzer, Professor of Surgery, Biomedical Engineering and Experimental Pathology at the University of Virginia and Beta-O2 Scientific Advisory Board member, explained that after years of insulin injections and closed-loop insulin pumps and glucose sensors, patients will finally have access to a biological device solution to treat the most brittle forms of diabetes. The Beta-O2 device is the only implant that has shown reproducible results in humans with diabetes, with measurable insulin production originating from human islet cells within the device without the need for recipients to take any immunosuppressive drugs.

An earlier safety trial involving four patients in Sweden, supported by New York-based JDRF (Juvenile Diabetes Research Foundation), successfully demonstrated that Beta-O2s device is fully safe for use. No side effects were observed in patients who carried the device for up to 10 months, and the cells remained viable and functional.

Now, current animal trials underway at Beta-O2 are focused on extending the life of functional cells even further, with promising early results showing that rats implanted with Air are maintaining normal glucose levels.

With tangible evidence that we can maintain the viability and functionality of our cells for a long duration in rats, which have an immune system very similar to humans, we are looking forward to moving ahead with our second round of human clinical trials, Lichter said, noting that the company aims to be first to show that implanted biological pancreatic cells can successfully achieve normal blood sugar levels in diabetic patients without the need for immunosuppression therapy.

First-of-its-Kind Bio-Artificial Pancreas on Track for Type-I Diabetes Cure - Global Trade Magazine

"Signs of cancer can appear long before diagnosis," reports The Guardian.

Most cells in the body divide and reproduce constantly, picking up replication errors in their DNA over time as we age. Many of these errors may be harmless, but some can cause or increase the risk of cancer.

Cancers begin when harmful errors, or mutations, cause our cells to divide in an uncontrolled way. It's usually impossible to tell if this is happening, until the cancer starts to cause physical signs or symptoms.

In this new study, an international team of researchers sequenced the genomes (the entire DNA and genetic material) of 2,658 tumour samples.

They used the information to work out the order in which mutations and copying of mutations happened, because usually more than one mutation is needed before cells become cancerous. The researchers then modelled how different types of cancer develop over time.

They found that harmful mutations for some types of cancer, such as ovarian cancer, characteristically happen very early, in some cases decades before people have any physical signs of the disease. The findings raise hopes that some cancers could be detected and treated much earlier.

However, at present it's not clear whether this research could lead to a cancer screening system based on checking for "genetic early warning signs", both in terms of effectiveness and feasibility.

At present, the best way to detect cancer early is to be alert to the possible signs and symptoms, attend cancer screening when invited, and know about your family history of the disease.

Find out more about:

The research was carried out by the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, an enormous collaboration between hundreds of scientists from 4 continents. 46 scientists worked on this particular paper, from 38 universities or research institutes.

The PCAWG group published 6 papers this week, but we're focusing on just 1, which looked at the way cancers evolve over time. The study was published in the peer-reviewed journal Nature on an open-access basis, so it is free to read online.

The Guardian, BBC News and Mail Online focused on the discovery that DNA changes to cells may happen many years before cancer can currently be diagnosed, and the reporting was generally accurate.

This was a modelling study, using data from the whole genome sequencing of 2,658 cancers to reconstruct the likely evolution of DNA in these cancers over time. The study helps scientists to better understand how cancers begin and evolve.

However, at this stage, the results cannot be used to test for cancers in people.

A team of scientists worldwide worked with 2,778 samples of cancers, taken from 2,658 people with cancer. Some people gave just 1 sample, while others gave a sample of newly diagnosed primary tumours, and later, a sample of a metastatic cancer (when cancer has spread to another part of the body). 38 cancer types were represented in the samples.

The scientists carried out whole genome sequencing of the samples. This showed where DNA mutations arose, and whether they had been copied and duplicated as more DNA changes accumulated.

Researchers could look for so-called "driver" mutations, which are known to be linked to cancer, and see whether they happened early or late in the cancer's evolution.

They used this information to model a typical "life history" for each of the 38 types of cancer. This showed whether important mutations happened early or late in the cancer's development. They then estimated how that mapped against a person's life. For example, whether cancer-causing mutations happened a short time before cancer was diagnosed, or whether they had been present for years or decades before cancer was detected.

The researchers found that the time between cancer-driving mutations and diagnosis varies a lot between cancers. Some (such as liver and cervical cancer) happen 1 to 5 years before the cancer was diagnosed. By contrast, ovarian cancers showed significant mutations 10 to 40 years before diagnosis. This suggests the original mutations that lead to some adult cancers could happen during childhood or adolescence.

Other results included:

The researchers said: "Our study sheds light on the typical timescale of tumour development, with initial driver events seemingly occurring up to decades before diagnosis." They say the results "highlight opportunities for early cancer detection."

This study represents an enormous achievement by many scientists working together to find out more about how cancers develop over time. This type of work is likely to be important in developing future tests for cancers, and possibly new treatments that can target cancers at a very early stage.

However, the study does not change how cancer is diagnosed or treated at present. It can take years before early-stage research like this leads to changes in clinical practice.

As one of the scientists involved in the study told journalists, the idea of being able to target mutations by doing blood tests during childhood, then eliminate dangerous mutations, is "science fiction".

This research is very complex and, as with all modelling, it relies on some assumptions about the time it takes for mutations to arise, be duplicated and copied. The accuracy of the findings will depend on the accuracy of these assumptions.

All samples in the study came from people who had developed cancer. It would be interesting to compare findings with non-cancerous tissue samples from these people, or samples from people who did not develop cancer.

It's good news that DNA sequencing technology now allows scientists to work on such a large scale, and that theyre able to work together to find out more detail about the way that cancers evolve. This type of work could make a big difference to the way doctors approach cancer in future.

Could findings of large new study change how cancer is diagnosed and treated - NHS Website

People who develop Parkinson's disease at a younger age (before age 50) may have malfunctioning brain cells at birth, according to a study that also identified a drug that may help these patients.

At least 500,000 people in the United States are diagnosed with Parkinson's each year. Most are 60 or older at diagnosis, but about 10% are between 21 and 50.

Parkinson's is a neurological disease that occurs when brain neurons that make dopamine become impaired or die. Dopamine helps coordinate muscle movement.

Symptoms get worse over time and include slow gait, rigidity, tremors, and loss of balance. There is currently no cure.

"Young-onset Parkinson's is especially heartbreaking because it strikes people at the prime of life," said study co-author Dr. Michele Tagliati, director of the Movement Disorders Program at Cedars-Sinai Medical Center in Los Angeles.

"This exciting new research provides hope that one day we may be able to detect and take early action to prevent this disease in at-risk individuals," he said in a hospital news release.

For the study, Tagliati and colleagues generated special stem cells from the cells of patients with young-onset Parkinson's disease. These stem cells can produce any cell type of the human body. Researchers used them to produce dopamine neurons from each patient and analyzed those neurons in the lab.

The dopamine neurons showed two key abnormalities: buildup of a protein called alpha-synuclein, which occurs in most forms of Parkinson's disease; and malfunctioning lysosomes, structures that act as "trash cans" for the cell to break down and dispose of proteins. This malfunction could result in a buildup of alpha-synuclein, the researchers said.

"Our technique gave us a window back in time to see how well the dopamine neurons might have functioned from the very start of a patient's life," said senior author Clive Svendsen, director of the Cedars Sinai Board of Governors Regenerative Medicine Institute.

"What we are seeing using this new model are the very first signs of young-onset Parkinson's," Svendsen said in the release. "It appears that dopamine neurons in these individuals may continue to mishandle alpha-synuclein over a period of 20 or 30 years, causing Parkinson's symptoms to emerge."

The study was published Jan. 27 in the journalNature Medicine.

The researchers also tested drugs that might reverse the neuron abnormalities. A drug called PEP005 already approved by the U.S. Food and Drug Administration for treating precancers of the skin reduced elevated levels of alpha-synuclein both in mice and in dopamine neurons in the lab.

The investigators plan to determine how PEP005, which is available in gel form, might be delivered to the brain to potentially treat or prevent young-onset Parkinson's.

They also want to find out whether the abnormalities in neurons of young-onset Parkinson's patients also exist in other forms of Parkinson's.

When talented rugby player George Thompson went to see his doctor with a suspected match-related injury, the last thing he expected to hear was the word 'cancer'.

George Thompson had been playing rugby since the age of six, spending most of his young sporting career at Devonport Services RFC, representing Devon U15s, captaining Devon U16s and Plymouth Albion U18s, before joining the Exeter Chiefs Academy.

The 17-year-old, from Saltash, was set to join his local club, Saltash RFC, but in a devastating and unexpected blow has had to give up the sport he loves after being diagnosed with Neuroblastoma.

The rare type of cancer mostly affects babies and young children, but very occasionally is found in adolescents.

George, who is in his second year of a gas engineering apprenticeship with Plymouth Community Homes, began suffering with lower back pain and was originally told that it was believed he had ankylosing spondylitis - a long-term condition which means the spine and other areas of the body become inflamed.

But after numerous scans and tests, he was told he had the rare cancer, which had also spread to his bones and bone marrow.

He has now been transferred to Bristol Royal Hospital for children where he is undergoing chemotherapy.

George now has a 12-month plan which will include surgery, chemotherapy, blood transfusions, radiotherapy and immunotherapy.

More than 13,800 has been raised on a crowdfunding page - which you can donate to here - set up by George's auntie, Catherine Arris.

George's sister, Rosie, said the "response has been overwhelming".

She said the money will help herself, her mother Julie and father, Martin with travel costs and subsidise their lost income whilst frequently making back-and-forth trips from Cornwall to Bristol, to ensure that they are with George throughout "the intense treatment period".

Rosie said: "This will also enable George to have some quality downtime away from the hospital ward when he is well enough in-between treatments.

"It is important to us that we maintain as normal a family life as possible throughout the difficult months that lie ahead and this is now being made possible by the generosity of so many people.

"There are not enough words to thank each and every person who is supporting us."

Rosie explained that any money which remains at the end of George's treatment will be donated to Clic Sargent, The Teenage Cancer Trust and Neuroblastoma UK.

"These charities are already looking after us, providing accommodation and various support," she said.

George has already undergone four blood transfusions and it is likely he will receive further transfusions.

Rosie said: "We are all signing up to donate blood and would encourage as many people as possible to follow suit. We have seen first hand how important blood donations are.

"In such a short space of time we have been amazed by the generosity and heartfelt messages of support.

"Georges fun loving character and caring nature has been recognised by so many people, some who have never met George."

There are a number of plans for fund-raising events to take place during Georges treatment, to raise money for Clic Sargent and the Teenage Cancer Trust.

Plymouth Community Homes is set to arrange an event, as well as a team named 'Run For George' which has entered into the Mudstock Run on June 27, 2020, supported by BH Fitness.

There is also a fund-raising rugby match on April 18, 2020, which has been organised by George's uncle, Richard Thompson.

Neuroblastoma is a rare type of cancer that mostly affects babies and young children.

It develops from specialised nerve cells (neuroblasts) left behind from a baby's development in the womb.

Neuroblastoma most commonly occurs in 1 of the adrenal glands situated above the kidneys, or in the nerve tissue that runs alongside the spinal cord in the neck, chest,tummy or pelvis.

It can spread to other organs, such as the bone marrow, bone, lymph nodes, liver and skin.

It affects around 100 children each year in the UK and is most common in children under the age of 5.

The cause is unknown. There are very rare cases where children in the same family are affected, but generally neuroblastoma does not run in families.

The symptoms of neuroblastoma vary depending on where the cancer is and whether it's spread.

The early symptoms can be vague and hard to spot, and can easily be mistaken for those of more common childhood conditions.

Symptoms can include:

See a GP or contactNHS 111if you're worried your child might be seriously ill.

A number of tests may be carried out if it's thought your child could have neuroblastoma.

These tests may include:

Once these tests have been completed, it'll usually be possible to confirm if the diagnosis is neuroblastoma and determine what stage it is.

As with most cancers, neuroblastoma is given a stage. This indicates if it's spread and, if so, how far.

The staging system used for neuroblastoma is:

Knowing the stage of your child's neuroblastoma will allow doctors to decide which treatment is best.

Some babies and infants less than 18 months old with either stage L1 or Ms neuroblastoma who have no symptoms may not need any treatment, as the cancer can sometimes go away on its own.

The main treatments for neuroblastoma are:

Like most medical students, I struggled to memorize the Krebs cycle, the complex energy-producing process that takes place in the body's mitochondria. Rote learning of Sir Hans Krebs' eponymous cascade of reactions persists and has been cited as a waste of time in modern medical education. However, it looks like that specialized knowledge about mitochondrial structure and function may finally come in handy in the clinic.

Advances in genetics have contributed to improved diagnostic accuracy of a diverse spectrum of mitochondrial disorders. Respiratory chain, nuclear gene, and mitochondrial proteome mutations can lead to multisystem or organ-specific dysfunction.

A new potential treatment for mitochondrial disorders, elamipretide, has received orphan drug designation from the US Food and Drug Administration (FDA) and is in clinical trials sponsored by Stealth Biotherapeutics. [Dr Wilner has consulted for Stealth Biotherapeutics.] Recently I had the opportunity to interview Hilary Vernon, MD, PhD, associate professor of genetic medicine at Johns Hopkins University, Baltimore, Maryland, and an expert on mitochondrial disorders. Dr Vernon discussed her research on elamipretide as a treatment for Barth syndrome, a rare form of mitochondrial disease.

I am the director of the Mitochondrial Medicine Center at Johns Hopkins Hospital. I work with individuals from infancy through adulthood who have mitochondrial conditions. I became interested in this particular area when I was early in my pediatrics/genetics residency at Johns Hopkins and saw the toll that mitochondrial disorders took on patients' lives and the limited effective therapies. At that point, I decided to focus on patient care and research in this area.

Mitochondrial disorders can be difficult to recognize because of their inherent multisystem nature and variable presentations (even between affected members of the same family). However, there are several considerations that should raise a clinician's suspicion for a mitochondrial condition. Ascertaining a family history of disease inheritance through the maternal line can raise the suspicion for a mitochondrial DNA disorder. Identification of a combination of medical issues in different organ systems that are seemingly unrelated in an individual (ie, optic atrophy and muscle weakness or diabetes and hearing loss) can also raise suspicion for a mitochondrial condition.

Due to the nature of mitochondria as the major energy producers of the cells, high-energy-requiring tissues such as the brain and the muscles are often affected. Perhaps the best known mitochondrial diseases to neurologists are MELAS (mitochondrial encephalopathy, lactic acidosis, and stroke) as well as MERFF (myoclonic epilepsy with ragged red fibers). There is a nice body of literature on the effects of arginine and citrulline in modifying stroke-like episodes in MELAS, and this is a therapy that is in current practice.

Mitochondria are complex organelles whose structure and function are encoded in hundreds of genes originating from both the nucleus of the cell and the mitochondria themselves. Mitochondria have many key roles in cellular function, including energy production through the respiratory chain, coordination of apoptosis, nitrogen metabolism, fatty acid oxidation, and much more.

Various cofactors and vitamins can be employed to improve mitochondrial function for different reasons. For example, if a specific enzyme is dysfunctional, supplying the cofactor for that enzyme may improve its function (ie, pyruvate dehydrogenase and thiamine). Antioxidants have also been considered to help reduce the oxidant load that could potentially cause ongoing damage to the mitochondrial membrane resulting from respiratory chain dysfunction (ie, coenzyme Q-10).

It is important to remember that the highest number of individual mitochondrial disorders result from mutations in genes located in the nuclear DNA. For example, the TAZ gene that is abnormal in Barth syndrome is a nuclear gene located on the X chromosome. These genes are amenable to the "regular" approaches to gene therapy.

Targeting mitochondrial DNA for gene therapy requires a different set of approaches because the gene delivery has to overcome the barrier of the mitochondrial membranes. However, research is ongoing to overcome these obstacles.

Barth syndrome is a very rare genetic X-linked disorder that usually only affects males. The genetic defect leads to an abnormal composition of cardiolipin on the inner mitochondrial membrane. Cardiolipin is an important phospholipid involved in many mitochondrial functions, including organization of inner mitochondrial membrane cristae, involvement in apoptosis, and organization of the respiratory chain (which is responsible for producing ATP via the process of oxidative phosphorylation), and many of these functions are abnormal in Barth syndrome. Individuals with Barth syndrome typically have early-onset cardiomyopathy, myopathy, intermittent neutropenia, fatigue, poor early growth, among other health concerns.

Early in my post-residency career, I followed several patients with Barth syndrome and was quickly welcomed into the Barth syndrome community by the families and the Barth Syndrome Foundation. From there, I founded the only interdisciplinary Barth syndrome clinic in the US and began to focus a significant amount of my clinical and laboratory research on this condition.

Most commonly, these individuals come to medical attention because of cardiomyopathy, but a minority of patients do come to attention due to repeated infections and neutropenia. Patients were identified for study participation through the Barth Syndrome Foundation or because they were already patients of my study team.

All participants were known to have Barth syndrome prior to study entry, and all had confirmatory genetic testing showing a pathogenic mutation in the TAZ gene.

By binding to cardiolipin in the inner mitochondrial membrane, elamipretide is believed to stabilize cristae architecture and electron transport chain structure during oxidative stress. I thought it would be great if this could help to stabilize the abnormal cardiolipin components on the inner mitochondrial membrane in Barth syndrome.

We observed improvements in several areas across the study population in the open-label extension part of the study. This includes a significant improvement in exercise performance (as measured by the 6-minute walk test, with an average improvement of 95.9 meters at 36 weeks) and a significant improvement in muscle strength. We also observed a potential improvement in cardiac stroke volume. Most of the adverse events were local injection-site reactions and were mild to moderate in nature.

The TAZPOWER trial has an ongoing open-label extension with the same endpoints as the placebo-controlled portion evaluated on an ongoing basis. In addition, in my laboratory, we are using induced pluripotent stem cells to learn more about how cardiolipin abnormalities affect different cell types in an effort to understand the tissue specificity of disease. This will help us to understand whether different aspects of Barth syndrome would necessitate individual management or clinical monitoring strategies.

Mitochondrial inner membrane dysfunction is increasingly recognized as a major aspect of the pathology of a wide range of mitochondrial conditions. Therefore, based on the role of stabilizing mitochondrial membrane components, elamipretide has a potential role in many disorders of the mitochondria.

Yes, this is what we would call "secondary mitochondrial dysfunction" (meant to differentiate from "primary mitochondrial disease," which is caused by defects in genes that encode for mitochondrial structure and function). Approaches intended to protect the mitochondria from further damage, such as antioxidants or strategies that can bypass the mitochondria for ATP production, could overlap as treatment for primary mitochondrial disease and secondary mitochondrial dysfunction.

This is something that is much discussed as a newer consideration for families who are affected by disorders of the mitochondrial DNA, but not something I have experience with firsthand.

Yes. The United Mitochondrial Disease Foundation and the Mitochondrial Medicine Society collaborated to develop the Mito Care Network, with 19 sites identified as Mitochondrial Medicine Centers across the US.

Anemia also known as iron-poor blood is a condition that develops when either the blood doesn't have enough red blood cells or the concentration of hemoglobin in red blood cells is very low. Hemoglobin is the iron-containing protein in red blood cells that carries oxygen from the lungs to the rest of the body. When there are fewer red blood cells than normal or low levels of hemoglobin, the body doesn't get enough oxygen-rich blood for healthy functioning, which is what causes the symptoms of anemia.

Anemia is the most common blood disorder in the United States, affecting nearly 3 million Americans, according to the Centers for Disease Control and Prevention (CDC).

The term anemia is a broad one that represents several hundred different conditions some of them mild and treatable, others that are quite serious, said Dr. Nancy Berliner, chief of hematology at Brigham and Women's Hospital in Boston. There are three reasons that people are anemic, Berliner said: Either their body can't make enough red blood cells, something is destroying the red blood cells faster than their body can make news ones or blood loss (from menstrual periods, colon polyps or a stomach ulcer, for example) is greater than blood cell production.

There are more than 400 different types of anemia, according to the Pacific Heart, Lung & Blood Institute. Here are a few of the more common and better understood types:

Iron-deficiency anemia: The most common form of anemia is caused by low-iron levels in the body. Humans need iron to make hemoglobin, and most of that iron comes from dietary sources. Iron-deficiency anemia can result from a poor diet or from blood loss through menstruation, surgery or internal bleeding.

Pregnancy also increases the body's need for iron because more blood is needed to supply oxygen to the developing fetus, which may quickly drain the body's available iron stores, leading to a deficit. Problems absorbing iron from food because of Crohn's disease or celiac disease can also result in anemia.

Vitamin deficiency anemia: Besides iron, the body also needs two different B-vitamins folate and B12 to make enough red blood cells. Not consuming enough B12 or folate in the diet or an inability to absorb enough of these vitamins can lead to deficient red blood cell production.

Sickle cell anemia or sickle cell disease (SDC): This inherited disease causes red blood cells to become crescent-shaped rather than round. Abnormally shaped red cells can break apart easily and clog small blood vessels, resulting in a shortage of red blood cells and episodes of pain, according to the Mayo Clinic. People become chronically anemic because the sickle-shaped red cells are not pliable and can't get through blood vessels to deliver oxygen, Berliner said.

SDC occurs most often in people from parts of the world where malaria is or was common, according to the CDC; the sickle cell trait may provide protection against severe forms of malaria. In the U.S., SDC affects an estimated 100,000 Americans.

Thalassemia: Thalassemia is an inherited blood disorder that results in lower-than-normal levels of hemoglobin. This type of anemia is caused by genetic mutations in one or more of the genes that control the production of hemoglobin, according to the National Heart, Lung & Blood Institute (NHLBI).

Aplastic anemia: Aplastic anemia is a rare, life-threatening condition that develops when bone marrow stops making enough new blood cells, including red cells, white cells and platelets.

Aplastic anemia may be caused by radiation and chemotherapy treatments, which can damage stem cells in bone marrow that produce blood cells. Some medications, exposure to toxic chemicals like pesticides, viral infections and autoimmune disorders can also affect bone marrow and slow blood cell production.

Hemolytic anemias: This disorder causes red blood cells to be destroyed faster than bone marrow can replace them. Hemolytic anemias may be caused by infections, leaky heart valves, autoimmune disorders or inherited abnormalities in red blood cells, according to the American Society of Hematology.

Anemia of inflammation: Also called anemia of chronic disease, anemia of inflammation commonly occurs in people with chronic conditions that cause inflammation. This includes people with infections, rheumatoid arthritis, inflammatory bowel disease, chronic kidney disease, HIV/AIDS and certain cancers, according to the National Institute of Diabetes and Digestive and Kidney Diseases.

When a person has a disease or infection that causes inflammation, the immune system responds in a way that changes how the body works, resulting in anemia. For example, inflammation suppresses the availability of iron, so the body may not use and store the mineral normally for healthy red blood cell production, Berliner said. Inflammation may also stop the kidneys from producing a hormone that promotes red blood cell production.

The risk for anemia is higher in people with a poor diet, intestinal disorders, chronic diseases and infections. Women who are menstruating or pregnant are also prone to the disorder.

The risk of anemia increases with age, and about 10% to 12% of people over 65 are anemic, Berliner said. But the condition is not a normal part of aging, so the cause should be investigated when it's diagnosed, she said. Older adults may develop anemia from chronic diseases, such as cancer, or iron-deficiency anemia from abnormal bleeding.

According to NHLBI, the following types of people have an increased risk of developing anemia:

Mild forms of anemia may not cause any symptoms. When signs and symptoms of anemia do occur, they may include the following, according to the NHLBI:

The first test used to diagnose anemia is a complete blood count, which measures different parts and features of the blood: It shows the number and average size of red blood cells, as well as the amount of hemoglobin. A lower-than-normal red blood cell count or low levels of hemoglobin indicate anemia is present.

If more testing is needed to determine the type of anemia, a blood sample can be examined under a microscope to check for abnormalities in the size and shape of the red cells, white cells and platelets.

The treatment of anemia depends on the specific type of anemia, Berliner said, and anemias caused by nutritional deficiencies respond well to changes in diet. People with iron-deficiency anemia may need to take supplemental iron for several months or longer to replenish blood levels of the mineral. Some people, especially pregnant women, may find it hard to take iron because it causes side effects, such as an upset stomach or constipation, Berliner said.

For vitamin-deficiency anemias, treatment with B12 or folate from supplements (or a B12 shot) and foods, can improve levels of these nutrients in the blood, Berliner said.

Serious problems, such as aplastic anemia, which involves bone marrow failure, may be treated with medications and blood transfusions. Severe forms of thalassemia might need frequent blood transfusions.

Treatment for sickle cell anemia may include pain medications, blood transfusions or a bone marrow transplant.

Bone marrow aspiration and trephine biopsy are usually performed on the back of the hipbone, or posterior iliac crest. An aspirate can also be obtained from the sternum (breastbone). For the sternal aspirate, the patient lies on their back, with a pillow under the shoulder to raise the chest. A trephine biopsy should never be performed on the sternum, due to the risk of injury to blood vessels, lungs or the heart.

The need to selectively isolate and concentrate selective cells, such as mononuclear cells, allogeneic cancer cells, T cells and others, is driving the market. Over 30,000 bone marrow transplants occur every year. The explosive growth of stem cells therapies represents the largest growth opportunity for bone marrow processing systems.

Request For Report Sample:https://www.trendsmarketresearch.com/report/sample/3184

Europe and North America spearheaded the market as of 2016, by contributing over 74.0% to the overall revenue. Majority of stem cell transplants are conducted in Europe, and it is one of the major factors contributing to the lucrative share in the cell harvesting system market.

In 2016, North America dominated the research landscape as more than 54.0% of stem cell clinical trials were conducted in this region. The region also accounts for the second largest number of stem cell transplantation, which is further driving the demand for harvesting in the region.Asia Pacific is anticipated to witness lucrative growth over the forecast period, owing to rising incidence of chronic diseases and increasing demand for stem cell transplantation along with stem cell-based therapy.

BENGALURU:Blood cancers could be leukaemia (of white blood cells), lymphoma (of Lymph nodes) or myelomas (of bone marrow) besides some other rare types. These are overall less common than breast, lung and prostate cancers, however, form a big subset of curable cancers.Generally, patients present with bleeding or infections and are mistaken for other causes and accidentally diagnosed with one of the above acute haematological/blood cancers. Acute leukaemia is more common in children.

Chronic leukaemia, on the other hand, are often diagnosed during routine health checkups with high blood counts and enlarged spleen. Often, myelomas present with renal dysfunction, low haemoglobin or bone fractures, and are missed during the early stages. While all these are extremely treatable, the key is to diagnose the problem on time.

Lymphomas present as lymph node swelling and form almost 60 per cent of all blood cancers and treated with some combinations of chemotherapies and biologics. Bone marrow transplantation (or stem cell transplantation) has an important role in haematological cancers. Autologous (own stem cells) and allogenic (donor stem cells) transplants are used.

There is 180-degree change in the way we diagnose and treat these set of disorders. High-end molecular diagnostics is basis of typing them enabling precision diagnosis and treatment. Monoclonal antibodies, inhibitors and small molecules (biologic therapies) make the treatment much more effective with lesser side effects.

Newer therapies like CAR-T (Chimeric Antigen Receptor-T) cell therapies are used for relapsed acute lymphoblastic leukaemia, large B cell lymphoma and myeloma. However cost of such therapies at this juncture is prohibitive. But with higher applications and wider utilisation, these genetic modification therapies will be more and more accessible.The author is medical oncologist andhemato-oncologist,Vikram Hospital, Bangalore

All you need to know about hematologic cancers - The New Indian Express

Bone Marrow Stem Cells Comments Off on All you need to know about hematologic cancers – The New Indian Express | February 6th, 2020

Machines intended to work in the body should probably be made out of cells from your body.

There are two stories I would like to tell with this edition of Business Unusual, the first is about the Darpa funded research to build robots out of living cells, the second is the incredible history of the animal that was used to build the first biological robots - Platannas.

The Defense Advanced Research Projects Agency (DARPA) is an agency of the American Department of Defense. It has funded many projects for military projects that in time have come to be used for civilian applications. The best-known example is the predecessor of the internet.

Why a military agency would fund research into creating living robots might be concerning but the stated objectives include managing environmental clean-ups or improving drug delivery which certainly are worthy pursuits. Of greater concern, are the ethical questions that are raised by creating new forms of a living organism. At the moment the designs dont attempt to make them self-replicating but that is part of the future plans.

Robots typically are designed and programmed to perform a specific task. Until now they would have been constructed out of non-living materials. These robots are also designed for a specific task but created from living cells. The choice of cell and the specific construction determines what action or function the living robot can perform.

One function that was attempted was movement. Starting from scratch researchers used stem cells from a frog to create skin cells and heart cells. The heart cells are muscles and so can contract while heart cells are able to do so rhythmically. Using those properties a machine learning program was tasked with testing thousands of configurations to determine which design would use the least cells to achieve the motion required. Once the best designs were determined, the living robots were constructed by researchers manipulating individual cells under a microscope.

The tiny constructed robots demonstrated that living robots designed by computer could offer an alternative to traditionally constructed machines. Future versions would look to make the constructions more complex and eventually able to self replicate.

One intended function was using a swarm of living robots with the ability to decompose plastic to be used to remove microplastics in the ocean. That may be a long way off, but if it is to become a reality the best time to start working on it is now.

Another application might be to not find plastic in the sea, but cancers in your body. Your body is already very good at doing so, but as we age and at certain times of our lives it becomes more challenging to correctly identify and kill cancer cells when they are still only tiny tumours.

This would require building robots consisting of your own body cells arranged in a way to allow them to move through the body and specifically find the corrupted cells. Adding them in numbers as we age may reduce the chance of developing tumours or even help the body recover after exposure to damaging external factors like sun damage to your skin.

This too is a long way off, but if successful and added to the many other options for extending and improving our lives then the research is most welcome.

Setting the other issues relating to building living robots aside, you might wonder why a frog from South Africa was chosen to build the first living robots.

It was not a random choice but points to a fascinating history that makes this particular frog one that has helped humanity overcome medical issues on a number of occasions.

A pregnancy test these days simply requires peeing on a stick. The reaction to a specific hormone in the urine can be isolated in minutes and let you know if you are pregnant within days of it occurring. It was not always this easy, the first method we are aware of would see a potentially pregnant woman urinate on ungerminated wheat and barley and wait a week or so to see if it germinated. Incredibly it works and was first mentioned over 3 000 years ago by the Egyptians. It was scientifically tested in the 1960s and found to be 70% accurate.

There were a variety of other methods used most on the expectation that something in the urine of females could be used to confirm pregnancy. In the 1920s it was injecting urine into female rabbits that after a day would require the examination of the rabbit ovaries. If swollen the woman was pregnant. In order to do the examination the rabbit was always killed and so the search continued for a better option.

Enter Lancelot Hogben, an English researcher lecturing in Cape Town in the early 1930s. He advised a student to consider using the local platanna as a potential for use as a model organism for biological tests. His hunch proved correct with Hillel Shapiro and Harry Zwarenstein creating the test to use the frog to indicate pregnancy.

The frog would be injected and in hours if the woman was pregnant would produce eggs. Not only was it accurate, but it also would not harm the frog which was easy to keep in a lab and would live for over a decade. As a result, the remarkable frog was exported around the globe and provided the answer to the question, am I pregnant, to the largest population explosion in our history. Most baby boomers parents and indeed many baby boomers would have found out if they were pregnant thanks to this strange-footed frog.

Xenopus literally means strange foot, frogs typically dont have claws which is why the African clawed frog got the name and as for Platanna, that may be a reference to the frog being very flat - plat in Afrikaans.

Given its widespread use for pregnancy and acceptance as a good species for embryonic development when researchers attempted to clone an organism, this frog was once again a key in understanding the process. In 1958, Xenopus was cloned not from splitting an embryonic cell which was the original method, but by using the DNA from an adult specialised cell which replaced the original DNA in a frog egg. The method proved successful and paved the way to allow Dolly the sheep to be cloned from an adult sheep cell in 1996.

We owe a huge debt of gratitude to six species that for a variety of reasons have helped us understand biological processes and how best to deal with disease and the efficacy of drugs. There are nematode worms, fruit flies, zebrafish, chickens, mice and the African clawed toad.

These six animals are our real guinea pigs.

Skin Stem Cells Comments Off on Biological robots, that is a thing now – CapeTalk | February 6th, 2020

Hip replacements, severe burns, spinal cord injuries, blast injuries, traumatic brain injuriesthese seemingly disparate traumas can each lead to a painful complication during the healing process called heterotopic ossification. Heterotopic ossification is abnormal bone formation within muscle and soft tissues, an unfortunately common phenomenon that typically occurs weeks after an injury or surgery. Patients with heterotopic ossification experience decreased range of motion, swelling and pain.

Currently, theres no way to prevent it and once its formed, theres no way to reverse it, says Benjamin Levi, M.D., Director of the Burn/Wound/Regeneration Medicine Laboratory and Center for Basic and Translational Research in Michigan Medicines Department of Surgery. And while experts suspected that heterotopic ossification was somehow linked to inflammation, new U-M research explains how this happens on a cellular scaleand suggests a way it can be stopped.

To help explain how the healing process goes awry in heterotopic ossification, the research team, led by Levi, Michael Sorkin, M.D. and Amanda Huber, Ph.D., of the Department of Surgerys section of plastic surgery, took a closer look at the inflammation process in mice. Using tissue from injury sites in mouse models of heterotopic ossification, they used single cell RNA sequencing to characterize the types of cells present. They confirmed that macrophages were among the first responders and might be behind aberrant healing.

Macrophages are white blood cells whose normal job is to find and destroy pathogens. Upon closer examination, the Michigan team found that macrophages are more complex than previously thoughtand dont always do what they are supposed to do.

Macrophages are a heterogenous population, some that are helpful with healing and some that are not, explains Levi. People think of macrophages as binary (M1 vs. M2). Yet weve shown that there are many different macrophage phenotypes or states that are present during abnormal wound healing.

Specifically, during heterotopic ossification formation, the increased presence of macrophages that express TGF-beta leads to an errant signal being sent to bone forming stem cells.

For now, the only way to treat heterotopic ossification is to wait for it to stop growing and cut it out which never completely restores joint function. This new research suggests that there may be a way to treat it at the cellular level. Working with the lab led by Stephen Kunkel, Ph.D. of the Department of Pathology, the team demonstrated that an activating peptide to CD47, p7N3 could alter TGF-beta expressing macrophages, reducing their ability to send signals to bone-forming stem cells that lead to heterotopic ossification.

During abnormal wound healing, we think there is some signal that continues to be present at an injury site even after the injury should have resolved, says Levi. Beyond heterotopic ossification, Levi says the studys findings can likely be translated to other types of abnormal wound healing like muscle fibrosis.

The team hopes to eventually develop translational therapies that target this pathway and further characterize not just the inflammatory cells but the stem cells responsible for the abnormal bone formation.

The paper is published in the journal Nature Communications. Other U-M authors include: Charles Hwang, William Carson IV, Rajarsee Menon, John Li, Kaetlin Vasquez, Chase Pagani, Nicole Patel, Shuli Li, Noelle D. Visser, Yashar Niknafs, Shawn Loder, Melissa Scola, Dylan Nycz, Katherine Gallagher, Laurie K. McCauley, Shailesh Agarwal, and Yuji Mishina.

Stem Cell Therapy Market: Snapshot

Of late, there has been an increasing awareness regarding the therapeutic potential of stem cells for management of diseases which is boosting the growth of the stem cell therapy market. The development of advanced genome based cell analysis techniques, identification of new stem cell lines, increasing investments in research and development as well as infrastructure development for the processing and banking of stem cell are encouraging the growth of the global stem cell therapy market.

To know Untapped Opportunities in the MarketCLICK HERE NOW

One of the key factors boosting the growth of this market is the limitations of traditional organ transplantation such as the risk of infection, rejection, and immunosuppression risk. Another drawback of conventional organ transplantation is that doctors have to depend on organ donors completely. All these issues can be eliminated, by the application of stem cell therapy. Another factor which is helping the growth in this market is the growing pipeline and development of drugs for emerging applications. Increased research studies aiming to widen the scope of stem cell will also fuel the growth of the market. Scientists are constantly engaged in trying to find out novel methods for creating human stem cells in response to the growing demand for stem cell production to be used for disease management.

It is estimated that the dermatology application will contribute significantly the growth of the global stem cell therapy market. This is because stem cell therapy can help decrease the after effects of general treatments for burns such as infections, scars, and adhesion. The increasing number of patients suffering from diabetes and growing cases of trauma surgery will fuel the adoption of stem cell therapy in the dermatology segment.

Global Stem Cell Therapy Market: Overview

Also called regenerative medicine, stem cell therapy encourages the reparative response of damaged, diseased, or dysfunctional tissue via the use of stem cells and their derivatives. Replacing the practice of organ transplantations, stem cell therapies have eliminated the dependence on availability of donors. Bone marrow transplant is perhaps the most commonly employed stem cell therapy.

Osteoarthritis, cerebral palsy, heart failure, multiple sclerosis and even hearing loss could be treated using stem cell therapies. Doctors have successfully performed stem cell transplants that significantly aid patients fight cancers such as leukemia and other blood-related diseases.

Global Stem Cell Therapy Market: Key Trends

The key factors influencing the growth of the global stem cell therapy market are increasing funds in the development of new stem lines, the advent of advanced genomic procedures used in stem cell analysis, and greater emphasis on human embryonic stem cells. As the traditional organ transplantations are associated with limitations such as infection, rejection, and immunosuppression along with high reliance on organ donors, the demand for stem cell therapy is likely to soar. The growing deployment of stem cells in the treatment of wounds and damaged skin, scarring, and grafts is another prominent catalyst of the market.

On the contrary, inadequate infrastructural facilities coupled with ethical issues related to embryonic stem cells might impede the growth of the market. However, the ongoing research for the manipulation of stem cells from cord blood cells, bone marrow, and skin for the treatment of ailments including cardiovascular and diabetes will open up new doors for the advancement of the market.

Global Stem Cell Therapy Market: Market Potential

A number of new studies, research projects, and development of novel therapies have come forth in the global market for stem cell therapy. Several of these treatments are in the pipeline, while many others have received approvals by regulatory bodies.

In March 2017, Belgian biotech company TiGenix announced that its cardiac stem cell therapy, AlloCSC-01 has successfully reached its phase I/II with positive results. Subsequently, it has been approved by the U.S. FDA. If this therapy is well- received by the market, nearly 1.9 million AMI patients could be treated through this stem cell therapy.

Another significant development is the granting of a patent to Israel-based Kadimastem Ltd. for its novel stem-cell based technology to be used in the treatment of multiple sclerosis (MS) and other similar conditions of the nervous system. The companys technology used for producing supporting cells in the central nervous system, taken from human stem cells such as myelin-producing cells is also covered in the patent.

Global Stem Cell Therapy Market: Regional Outlook

The global market for stem cell therapy can be segmented into Asia Pacific, North America, Latin America, Europe, and the Middle East and Africa. North America emerged as the leading regional market, triggered by the rising incidence of chronic health conditions and government support. Europe also displays significant growth potential, as the benefits of this therapy are increasingly acknowledged.

Asia Pacific is slated for maximum growth, thanks to the massive patient pool, bulk of investments in stem cell therapy projects, and the increasing recognition of growth opportunities in countries such as China, Japan, and India by the leading market players.

Cardiac Stem Cells Comments Off on Stem Cell Therapy Market Trends and Growth, Outlook, Research, Trends and Forecast to 2025 – Instant Tech News | February 6th, 2020

Research into alternative stem cell sources has identified urine derived renal progenitor cells (UdRPCs) as a possible option for use in regenerative kidney therapies in the future.

Scientists have demonstrated their protocol for the reproducible isolation of kidney stem cells from human urine. These urine derived renal progenitor cells (UdRPCs) could be used to provide easier access to stem cells for regenerative kidney therapies and modelling diseases for R&D.

A shortage of donor organs and the risks and pain associated with bone marrow stem cell extractions and third trimester amniotic fluid collection have encouraged researchers to find alternative sources of stem cells. According to scientists, several laboratories have indicated urine could be an alternative source, at least for kidney stem cells, so the researchers from Heinrich Heine University-Duesseldorf (HHU) Germany,set out to complete a comprehensive molecular and cellular analysis of these cells.

UdRPCs should be considered as the choice of renal stem cells for facilitating the study of nephrogenesis, nephrotoxicity, disease modelling and drug development

Their study, published in Scientific Reports, revealed that UdRPCs isolated from ten individuals express both markers typically seen in bone marrow-derived mesenchymal stem cells (MSCs) and renal stem cells. The renal stem cell markers, according to the paper, allow UdRPCs to be differentiated into cell types present in the kidney, eg, podocytes and the proximal and distal tubules. The study also showed that these progenitor cells have similar properties to amniotic fluid-derived stem cells (AFCs).

Wasco Wruck, bioinformatician and co-author of the study, said: It is amazing that these valuable cells can be isolated from urine and comparing all the genes expressed in UdRPCs with that derived from kidney biopies we could confirm their renal and renal progenitor cell properties and origin.

According to Martina Bohndorf, a study co-author, UdRPCs can also be easily and efficiently reprogrammed into induced pluripotent stem cells using a non-viral integration-free and safe method.

Dr James Adjaye, study senior author and professor at the Institute for Stem Cell Research and Regenerative Medicine (ISRM) in the medical faculty of HHU, revealed that one of the most promising options in the near future is the use of transplantable renal stem cells (UdRPCs) for treatment of kidney diseases as a complementary option to kidney organs. He concluded that human UdRPCs should be considered as the choice of renal stem cells for facilitating the study of nephrogenesis, nephrotoxicity, disease modelling and drug development.

Kidney stem cells isolated from urine could be regenerative therapies - Drug Target Review

'This is the beginning of my new life'

I thought my cancer diagnosis was a death sentence, said Lynnette Williams-Briggs, 60, of Seaford, Delaware, who was diagnosed with advanced B-cell lymphoma in 2018.

Briggs cancer is now in complete remission thanks to successful chimeric antigen receptor CAR-T cell therapy she received in August atChristianaCaresHelen F. Graham Cancer Center & Research InstitutesBone Marrow and Stem Cell Transplant Program.

I can breathe again. This is the beginning of my new life, Williams-Briggs said following the treatment that restored her hope for a second chance at life.

She was the first patient to receive CAR-T cell therapy in Delaware. A second patient was treated in December 2019, and doctors are preparing several more patients for CAR-T cell transplants in coming weeks.

The U.S. Food and Drug Administration has approved CAR-T cell therapy to treat patients like Williams-Briggs with highly resistant, B-cell blood cancers, for whom other available options have failed.

CAR-T cell therapy is only available at select cancer centers with specialized expertise in cellular therapies that are recognized for quality by the Foundation for the Accreditation of Cellular Therapy.

The Graham Cancer Centers Bone Marrow and Stem Cell Transplant Program is the only one in Delaware that is certified to treat adult patients with advanced B-cell lymphomas and children and young adults (to age 25) with acute lymphoblastic leukemia, using an FDA-approved drug.

CAR-T cell therapy is highly personalized medicine that attempts to use the bodys natural defenses to fight against cancer. The transplant team extracts millions of T cells, from the patients bloodstream, using a specialized blood filtration process called leukapheresis. The collected T cells are flash-frozen and sent to a lab for reprogramming, and then later infused back into the patient using a process similar to a blood transfusion.

The therapy is considered a living drug with potential benefits that could last for years.

When we first met Ms. Williams-Briggs, her cancer had progressed rapidly despite a third round of chemotherapy, so we knew we had to move quickly, said Graham Cancer Center Hematologist Peter Abdelmessieh, D.O. He worked closely with the bone marrow/stem cell transplant team and Graham Cancer Center leadership over the course of just eight months to develop the CAR-T cell therapy program.

It was truly a team effort to bring CAR-T cell therapy to our community so quickly, Dr. Abdelmessieh said.

CAR-T cell therapy has been extremely effective for many patients like Williams-Briggs, whose PET scan at 90 days confirmed her remission.

The supercharged T cells Williams-Briggs received were genetically modified in the lab to sprout new surface tools that improve their ability to recognize, latch onto and destroy other cells (including cancer cells) that express a specific antigen called CD19. These reprogrammed cells continue to multiply in the body after treatment, remaining on guard to seek and destroy any new cancers that might develop.

With continued success in increasing numbers of patients, it is conceivable that in the not too distant future, CAR-T cell therapy could become the new standard of care, replacing chemotherapy and stem cell transplants for many cancers, Dr. Abdelmessieh said.

The extended recovery period for CAR-T cell therapy is generally two to three months. After the infusion, patients may spend up to three weeks in the hospital to monitor treatment response and any side effects.

During the first 30 days after leaving the hospital, patients are required to remain close to the treatment center for regular follow-up care.

The ability to offer potentially life-saving CAR-T cell therapy is one more reason our patients need not travel further than the Graham Cancer Center for state-of-the-science cancer treatment, said Nicholas J. Petrelli, M.D., Bank of America medical director of the Helen F. Graham Cancer Center & Research Institute.

The Bone Marrow and Stem Cell Transplant Program is an outstanding example of how well our clinical teams work together to drive innovation in patient care.

Although patients normally do not experience the side effects associated with chemotherapy, such as nausea, vomiting or hair loss, CAR-T cell therapy is not without risks. A common side effect, which Williams-Briggs also experienced, is cytokine release syndrome. This is an inflammatory condition that causes flu-like symptoms that may be mild or severe.

The transplant team responded quickly to manage her symptoms while she received expert care on the Bone Marrow Transplant and Oncology unit at Christiana Hospital.

From the moment I first met with my transplant team, I felt like I was part of one big loving family that extended beyond my own loved ones, Williams-Briggs said.

Dr. Abdelmessieh and my ChristianaCare family gave me hope to keep fighting when I really didnt think I would make it. I would have driven anywhere to get life-saving treatment, but I am thankful that I did not have to. I found my miracle closer to home.

Mesoblast Tenders Completed Biologics License Application

Mesoblast Limited (MESO) announced that it has filed a completed Biologics License Application (BLA) with the United States Food and Drug Administration for its lead allogeneic cell therapy Ryoncil. The therapy is aimed at treating children with steroid-refractory acute graft versus host disease (SR-aGVHD).

Mesoblast submitted the final module of its rolling BLA submission on January 31, 2020. This module covers various aspects related to manufacturing and quality control. The drug candidate currently has Fast Track designation assigned to it and on the basis of this tag, the company is now seeking the FDA to carry out Priority Review of its BLA.

Subject to the approval of the therapy, the company is looking to launch it in the US markets in 2020. CEO Dr. Silviu Itescu said, "This is a major corporate milestone for Mesoblast." The company is expected to use the insights gained from its Temcell product in Japan for the marketing of Ryoncil.

Acute Graft versus Host disease affects nearly 50 percent of patients given an allogeneic Bone Marrow transplant. It is estimated that nearly 30,000 patients undergo bone marrow transplants worldwide. The mortality rate for patients suffering from actual GVHD is close to 90 percent. Currently, there is no FDA approved treatment for this in the United States for children under 12.

Ryoncil has been tested on 309 children suffering from SR-aGVHD during three different studies. It was employed as salvage therapy on 241 children with SR-aGVHD (80% Grade C/D) who failed institutional standard of care. It has also been tested as first line therapy for an open label Phase 3 trial in 55 children with SR-aGVHD. RYONCIL, is an investigational therapy comprising culture-expanded mesenchymal stem cells. These stem cells are taken from the bone marrow of an unrelated donor. The drug is administered to patients as intravenous infusions.

Mesoblast specializes in developing allogeneic cellular medicines. The company uses its proprietary cell therapy technology platform for research and development purpose. It has strong drug pipeline with products such as Remestemcel-L, Revascor, MPC-06-ID and MPC-300-IV. Revascor and MPC-06-ID have completed patient enrollment for its Phase 3 trials. The former drug candidate is aimed at treating advanced chronic heart failure while the latter is targeted at treating chronic low back pain caused by degenerative disc disease. The companys Temcell and Alofisel drugs are already approved in Japan and Europe, respectively.

Mesoblast has posted strong operative results as well. The company had reported 46 percent growth in its revenue during the first quarter of 2020. Mesoblast ended the quarter with $34.5 million in cash while its pro forma cash in hand stood at $100 million. The company also reported its strategic partnership with Grunenthal, which entitles Mesoblast to receive up to $150 million in upfront and milestone payments. The collaboration will also result in commercialization milestone payments. Such milestone payments have the potential to cross $1 billion mark.

Mesoblast stock has performed strongly in the market. The stock has charted over 200 percent in the past 12 months. Currently, it is trading close to its 52-week high of $10.88 and has potential to maintain its positive trajectory as the company forges ahead with its research and development activities and marketing efforts.

Waters Corporation (WAT) reported its fourth-quarter earnings and provided guidance for 2020. The company registered $716 million in revenue for the fourth quarter, in line with the revenue of $715 million it had reported for the corresponding quarter of the previous year. Its GAAP diluted earnings per share stood at $3.12 per share, up from $2.46 on year-on-year basis.

For the full fiscal year 2019, the companys revenue stood at $2.4 billion, down 1 percent from $2.42 billion in revenue it had earned in fiscal year 2018. The EPS for the fiscal year stood at $8.69, up from $7.65 for the previous year. The non GAAP EPS also increased from $8.29 to $8.99 for fiscal year 2019.

The company reported that its sales in both the pharmaceuticals and industrial market declined by 1 percent. However, its sales into the government and academic market grew 8 percent. Chris OConnell, Chairman and Chief Executive Officer of Waters Corporation, said, We were encouraged by the increasing impact in the fourth quarter of our new products launched during 2019.

While its full-year and fourth-quarter numbers were strong, the company provided rather lackluster guidance for fiscal year 2020. Waters Corporation expects its full-year revenue to increase by 1 percent to 3 percent. Its non GAAP EPS will likely remain between $9.15 and $9.40, lower than consensus estimate of $1.75. For its first quarter, Waters Corporations non GAAP EPS for the first quarter is expected to be in the range of $1.55 and $1.65. The consensus estimate for non GAAP EPS guidance was at $1.75.

EyePoint Pharmaceuticals (EYPT) reported its new exclusive licensing deal with Equinox Science. The deal involves the development of vorolanib for treating wet age-related macular degeneration, retinal vein occlusion and diabetic retinopathy. Vorolanib is a tyrosine kinase inhibitor.

EyePoint elaborated that its drug candidate EYP 1901, which incorporates vorolanib, uses a miniaturized, sustained release and injectable intravitreal drug delivery system offering six months duration. The company has used its bioerodible Durasert technology for this purpose. EyePoint is optimistic about the combination of vorolanib with Durasert technology for delivering superior results.

Under the terms of the agreement, EyePoint will take care of development and global commercialization of the treatment. However, the global commercialization will exclude China, Hong Kong, Taiwan and Macau regions. For this purpose, EyePoint will pay $1 million to Equinox Science as upfront payment. It will also pay development and regulatory milestones and post commercialization royalties.

EyePoint recently concluded a positive Type B pre investigational New Drug meeting with the FDA. The meeting clarified the pathway for a Phase 1 clinical trial. The company expects to present the data from Phase 1 trial during the second half of 2021. Nancy Lurker, President and Chief Executive Officer of EyePoint Pharmaceuticals, said, We are encouraged by the potential of vorolanib, as it demonstrated a promising Phase 1 and Phase 2 efficacy signal in prior human wAMD studies as an oral therapy and in preclinical animal studies as intravitreal EYP-1901.

EyePoint is a biopharma company specializing in developing novel ophthalmic products. The company currently has two products available in the market which are Dexycu and Yutiqu. The former is the first approved intraocular treatment for postoperative inflammation while the latter is a three-year treatment of chronic non-infectious uveitis affecting the posterior segment of the eye.
