Parkinsons disease is an illness that most often affects older people, but new research suggests it may actually be present in the brain right from birth and even earlier. Scientists from Cedars-Sinai have now found that in the brains of young-onset Parkinsons patients, malfunctioning neurons are always there but it takes 20 to 30 years for the symptoms to accumulate. Thankfully, a drug thats already on the market could help prevent the disease from taking hold if caught early enough.

Parkinsons disease primarily affects neurons in the brain that produce dopamine, eventually causing muscle weakness and stiffness, tremors, and balance problems. Most of the time, the disease is diagnosed in older people over the age of 60, but around 10 percent of cases occur in those aged between 21 and 50.

In a new study, scientists from Cedars-Sinai set out to investigate whether there were any early warning signs in the neurons of patients whod been diagnosed with Parkinsons before they turned 50. To do so, they created induced pluripotent stem cells (IPSCs) from young-onset Parkinsons patients, which can then be turned into almost any other cells in the body.

The researchers used the IPSCs to grow dopamine neurons in lab dishes. As they watched them develop, the team noticed that cell structures called lysosomes were malfunctioning. These structures are responsible for breaking down unneeded or worn-out proteins so when they dont work as well as they should, proteins begin to pile up. And one such protein that the team spotted in higher amounts is called alpha-synuclein, which is implicated in many forms of Parkinsons.

"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 patients life, says Clive Svendsen, senior author of the study. "What we are seeing using this new model are the very first signs of young-onset Parkinsons. It appears that dopamine neurons in these individuals may continue to mishandle alpha-synuclein over a period of 20 or 30 years, causing Parkinsons symptoms to emerge.

Next up, the team investigated whether the condition could potentially be treated or even prevented. After testing a series of drugs, they found one that looked promising PEP005, which has already been approved by the FDA for use against skin precancers. The researchers found that PEP005 works to reduce the levels of alpha-synuclein, as well as another abnormally-abundant enzyme called protein kinase C, whose role in Parkinson's remains unclear.

The treatment looks promising, but for now its only been shown to work in mice and lab-grown cells, so it wont necessarily translate to human trials. The team plans to continue working on this, as well as figuring out how to adapt PEP005 for use in the brain at the moment, its only available as a topical gel, since it's for treating skin cancer.

The research was published in the journal Nature Medicine.

In our regular feature #TheBrand, Bazaars beauty team look into an exciting and efficacious brand taking the beauty industry by storm. This time, its a doctor-backed skincare line combining luxury with lasting results.

In the past, weve happily soaked up skincare advice from celebrities, supermodels and self-appointed influencers. (In fact, weve even bought into brands created by them.) But now, those of us looking to settle down with a serious skincare regime one that promises a healthy, resilient complexion for good are rightfully turning to doctors for direction.

As we become increasingly invested in our skincare, favouring proven formulations over zeitgeisty trends, the door has been opened for a host of dermatologists, surgeons and doctors to launch their own brands. Armed with the best qualifications in the business, these experts combine ingredients knowledge with confidence, ensuring maximum potency with minimal contraindications.

The latest brand in this formidable category is MZ Skin, founded by Dr. Maryam Zamani. Not only is she a leading oculoplastic surgeon (aka eye doctor), but she's also one of London's most in-demand aesthetic doctors, working out of the Cadogan Clinic in Chelsea.

With a background in medical science, Zamani is perfectly positioned to create clinically proven products that speak to womens needs, providing a direct path to the balanced and healthy skin were all hoping to obtain. Truly understanding the actives, how they interact with the skin and what they can achieve is imperative in formulating powerful results, she says.

While most dermatologist and doctor-led brands tend to sit on the cold, clinical side of the skincare fence, MZ Skin is a visibly luxurious affair. Most of the doctor ranges now are made by men for women, which often means we lose an important aspect of skincare and wellness, explains Zamani, who treasures the sense of ritual in her own routine, seeing it as a powerful self-care tool. Taking a few moments to do something that is good for you and feels good to do has compounded positive impact.

Proven actives are, unsurprisingly, the focal point of MZ Skin here, you can find some of the most effective brightening, rejuvenating and repairing formulas around.

Expect familiar ingredients in optimum levels of potency, and always stabilised for longevity. Vitamin C, peptides, acids, ceramides, stem cells and most recently retinol form the basis. Everything is free from mineral oil, (a harmless yet useless filler ingredient), and controversial paraben preservatives.

Naturally, Zamanis Soothe & Smooth eye cream is a stand-out. Hyaluronic acid provides moisture while ceramides strengthen the skin barrier, but its the unusual addition of albazia bark extract that proves her skincare nous. Also known as Persian silk tree extract, it is said to encourage the skin to produce collagen and elastin, leading to less surface lines.

If youre looking for a quick fix, the Radiance & Renewal mask is worth a try, but the savviest shoppers will head instead for the Cleanse & Clarify cleanser. Ticking off two steps in one, it can be used nightly as a deep cleanser, or left to linger as a pre-event mask. The hefty dose of alpha-hydroxy acids sloughs away dead skin cells, leaving skin looking brighter immediately after use.

Several brands are investing in at-home LED technology now, but MZ Skins Light Therapy Golden Facial Device is one of the most advanced available outside of a professional setting, thanks to the impressive five shades of LED it emits.

Light emitting diodes send out specific wavelengths that are then absorbed by the skin," explains Zamani. Red and yellow light helps boost collagen production, while blue light kills bacteria that can lead to acne. Green LED can be absorbed by melanin in the skin to help improve the appearance of pigmentation.

But it's the inclusion of a fifth light setting that make's Zamani's device a true stand-out. White, or near-infrared light, penetrates remarkably deep into the dermis to promote wound healing and skin repair: a benefit scarcely found in at-home devices.

LOS ANGELES Extending everyones life in a healthy fashion is one of many goals held by Peter Diamandis, a space, technology, aeronautics and medicine pioneer. But the new field known as longevity is of interest to everyone.

One hundred will be the new 60, he told his Abundance360 conference recently. The average human health span will increase by 10+ years this decade.

He, like others in Silicon Valley, believe that aging is a disease and the result of planned obsolescence, or the wearing down of, or damage to, certain critical mechanisms, sensors and functions within our bodies. Longevity research is about identifying the core problems to mitigate or reverse them.

The average human health span will increase by 10+ years this decade

Peter Diamandis

The exponential technologies of artificial intelligence, machine learning and computational heft have been harnessed, and have resulted in breakthroughs and clinical trials that are just a handful of years away from deployment on human patients. The main areas of research include: Stem cell supply restoration, regenerative medicine to regrow damaged cartilage, ligaments, tendons, bone, spinal cords and neural nerves; vaccine research against chronic diseases such as Alzheimers; and United Therapeutics that is developing technology to tackle the organ shortage for humans by genetically engineering organs grown in pigs.

New tools are accelerating the development of new, tailor-made medicines at a fraction of todays costs. Alex Zhavoronkov of Insilico Medicine told the conference that drugs take 10 years and cost $3 billion to research and 90 per cent fail. But his company can test in 46 days using human tissue, then model, design and produce in weeks with the help of advanced computing.

In regenerative medicine, advances appear to be arriving relatively soon. For instance, Diamandis asked the audience if anyone was awaiting a knee replacement operation and suggested that they might be better off postponing these until 2021 when regenerative medicine innovator, Samumed LLC in San Diego, is expected to complete phase three clinical trials of cartilage regeneration.

Samumeds founder, Osman Kibar, said his company has successfully injected a protein that activates nearby stem cells into producing new cartilage in a knee or a new disc in a spine. Preliminary success has also occurred to regenerate muscle and neural cells, retinal cells, skin and hair. Not surprisingly, the private company just raised US$15.5 billion to continue research and product development.

Another hot area of early stage research is called epigenetic reprogramming or identifying how to reverse deficiencies in proteins, stem cells, chromosomes, genes that repair DNA and damaged cells. A leader in this field is David Sinclair, professor of genetics at the Harvard Medical School, whose new book Lifespan: Why We Age and Why We Dont Have To explains the science and offers advice.

Aging is a disease, and that disease is treatable, he said. As research progresses toward actual corrections or cures, there are also lifestyle habits that can slow down the aging process, or avert damage. For instance, he said humans should replicate some behaviour that their bodies were designed for. Obviously, exercising and sleep are necessary but so is eating less often. You should feel hungry regularly, he said.

Another condition that is useful to emulate is hormesis, a scientific term for what Neitzsche posited which was that that which does not kill us makes us stronger. Sinclair recommends stressing our bodies with temperature changes such as going from a hot sauna to rolling in the snow. This invigorates the bodys processes and cells.

Theres also xenohormesis or gaining benefits from eating plants that have been environmentally stressed, therefore contain more beneficial nutrients. For instance, drought-stressed or wild strawberries have better flavour but they also are enhanced with additional antioxidant capacity and phenol content.

The age of 100 is easily in sight now, said Diamandis. And kids born today can expect to live to 105.

With so many groundbreaking medical advances being revealed to the world every single day, you would imagine there would be some advancement on the plethora of many female-prevalent diseases (think female cancers, Alzheimer's, depression, heart conditions etc.) that women are fighting every single day.

For Anna Villarreal and her team, there frankly wasn't enough being done. In turn, she developed a method that diagnoses these diseases earlier than traditional methods, using a pretty untraditional method in itself: through your menstrual blood.

Getting from point A to point B wasn't so easy though. Villarreal was battling a disease herself and through that experience. I wondered if there was a way to test menstrual blood for female specific diseases," she says. "Perhaps my situation could have been prevented or at least better managed. This led me to begin researching menstrual blood as a diagnostic source. For reasons the scientific and medical community do not fully understand, certain diseases impact women differently than men. The research shows that clinical trials have a disproportionate focus on male research subjects despite clear evidence that many diseases impact more women than men."

There's also no denying that gap in women's healthcare in clinical research involving female subjects - which is exactly what inspired Villarreal to launch her company, LifeStory Health. She says that, with my personal experience everything was brought full circle."

There is a challenge and a need in the medical community for more sex-specific research. I believe the omission of females as research subjects is putting women's health at risk and we need to fuel a conversation that will improve women's healthcare.,"

-Anna Villarreal

Her brand new biotech company is committed to changing the women's healthcare market through technology, innovation and vocalization and through extensive research and testing. She is working to develop the first ever, non-invasive, menstrual blood diagnostic and has partnered with a top Boston-area University on research and has won awards from The International Society for Pharmaceutical Engineering and Northeastern University's RISE.

How does it work exactly? Proteins are discovered in menstrual blood that can quickly and easily detect, manage and track diseases in women, resulting in diseases that can be earlier detected, treated and even prevented in the first place. The menstrual blood is easy to collect and since it's a relatively unexplored diagnostic it's honestly a really revolutionary concept, too.

So far, the reactions of this innovative research has been nothing but excitement. The reactions have been incredibly positive." she shares with SWAAY. Currently, menstrual blood is discarded as bio waste, but it could carry the potential for new breakthroughs in diagnosis. When I educate women on the lack of female subjects used in research and clinical trials, they are surprised and very excited at the prospect that LifeStory Health may provide a solution and the key to early detection."

To give a doctor's input, and a little bit more of an explanation as to why this really works, Dr. Pat Salber, MD, and Founder of The Doctor Weighs In comments: researchers have been studying stem cells derived from menstrual blood for more than a decade. Stem cells are cells that have the capability of differentiating into different types of tissues. There are two major types of stem cells, embryonic and adult. Adult stem cells have a more limited differentiation potential, but avoid the ethical issues that have surrounded research with embryonic stem cells. Stem cells from menstrual blood are adult stem cells."

These stem cells are so important when it comes to new findings. Stem cells serve as the backbone of research in the field of regenerative medicine the focus which is to grow tissues, such as skin, to repair burn and other types of serious skin wounds.

A certain type of stem cell, known as mesenchymal stem cells (MenSCs) derived from menstrual blood has been found to both grow well in the lab and have the capability to differentiate in various cell types, including skin. In addition to being used to grow tissues, their properties can be studied that will elucidate many different aspects of cell function," Dr. Salber explains.

To show the outpour of support for her efforts and this major girl power research, Villarreal remarks, women are volunteering their samples happily report the arrival of their periods by giving samples to our lab announcing de-identified sample number XXX arrived today!" It's a far cry from the stereotype of when it's that time of the month."

How are these collections being done? Although it might sound odd to collect menstrual blood, plastic cups have been developed to use in the collection process. This is similar to menstrual products, called menstrual cups, that have been on the market for many years," Dr. Salber says.

Equally shocking and innovative, this might be something that becomes more common practice in the future. And according to Dr. Salber, women may be able to not only use the menstrual blood for early detection, but be able to store the stem cells from it to help treat future diseases. Companies are working to commercialize the use of menstrual blood stem cells. One company, for example, is offering a patented service to store menstrual blood stem cells for use in tissue generation if the need arises."

When Marie Antoinette was captured during the French Revolution, her hair reportedly turned white overnight. In more recent history, former U.S. Senator John McCain experienced severe injuries as a prisoner during the Vietnam Warand lost color in his hair.

For a long time, anecdotes have connected stressful experiences with hair-graying.

Get more HMS news here

Now, for the first time, Harvard University scientists have discovered exactly how the process plays out: stress activates nerves that are part of the fight-or-flight response, which in turn cause permanent damage to pigment-regenerating stem cells in hair follicles.

The work, published inNature, details the molecular mechanisms behind the longstanding biological puzzle.

Everyone has an anecdote to share about how stress affects their body, particularly in their skin and hairthe only tissues we can see from the outside, said senior authorYa-Chieh Hsu, the Alvin and Esta Star Associate Professor of Stem Cell and Regenerative Biology at Harvard. We wanted to understand if this connection is true, and if so, how stress leads to changes in diverse tissues. Hair pigmentation is such an accessible and tractable system to start with, and besides, we were genuinely curious to see if stress indeed leads to hair-graying.

Fingering the culprit

Because stress affects the whole body, researchers first had to narrow down which body system was responsible for connecting stress to hair color. The team first hypothesized that stress causes an immune attack on pigment-producing cells. However, when mice lacking immune cells still showed hair-graying, researchers turned to the hormone cortisol. Once more, it was a dead end.

Stress always elevates levels of the hormone cortisol in the body, so we thought that cortisol might play a role, Hsu said. But surprisingly, when we removed the adrenal gland from the mice so that they couldnt produce cortisol-like hormones, their hair still turned gray under stress.

After systematically eliminating different possibilities, researchers homed in on the sympathetic nervous system, which is responsible for the bodys fight-or-flight response.

Sympathetic nerves branch out into each hair follicle on the skin. The researchers found that stress causes these nerves to release the chemical norepinephrine, which gets taken up by nearby pigment-regenerating stem cells.

Permanent damage

In the hair follicle, certain stem cells act as a reservoir of pigment-producing cells. When hair regenerates, some of the stem cells convert into pigment-producing cells that color the hair.

Researchers found that the norepinephrine from sympathetic nerves causes the stem cells to activate excessively. The stem cells all convert into pigment-producing cells, prematurely depleting the reservoir.

When we started to study this, I expected that stress was bad for the body, but the detrimental impact of stress that we discovered was beyond what I imagined, Hsu said. After just a few days, all of the pigment-regenerating stem cells were lost. Once theyre gone, you cant regenerate pigments anymore. The damage is permanent.

The finding underscores the negative side effects of an otherwise protective evolutionary response, the researchers said.

Acute stress, particularly the fight-or-flight response, has been traditionally viewed to be beneficial for an animals survival. But in this case, acute stress causes permanent depletion of stem cells, said postdoctoral fellow Bing Zhang, the lead author of the study.

Answering a fundamental question

To connect stress with hair-graying, the researchers started with a whole-body response and progressively zoomed into individual organ systems, cell-to-cell interaction and, eventually, all the way down to molecular dynamics. The process required a variety of research tools along the way, including methods to manipulate organs, nerves and cell receptors.

To go from the highest level to the smallest detail, we collaborated with many scientists across a wide range of disciplines, using a combination of different approaches to solve a very fundamental biological question, Zhang said.

One of the study collaborators wasIsaac Chiu, assistant professor of immunology in the Blavatnik Institute at Harvard Medical School, who studies the interplay between the nervous and immune systems.

We know that peripheral neurons powerfully regulate organ function, blood vessels and immunity, but less is known about how they regulate stem cells, Chiu said.With this study, we now know that neurons can control stem cells and their function and can explain how they interact at the cellular and molecular levels to link stress with hair-graying.

The findings can help illuminate the broader effects of stress on various organs and tissues. This understanding will pave the way for new studies that seek to modify or block the damaging effects of stress.

By understanding precisely how stress affects stem cells that regenerate pigment, weve laid the groundwork for understanding how stress affects other tissues and organs in the body, Hsu said. Understanding how our tissues change under stress is the first critical step towards eventual treatment that can halt or revert the detrimental impact of stress. We still have a lot to learn in this area.

Cancer patients could be treated with a one-size-fits-all therapy, following the discovery of an immune cell which kills all forms of the disease.

Researchers at Cardiff University have found a new type of killer T-cell, capable of recognising and destroying most human cancers while preserving healthy cells. The scientists discovered a method of killing prostate, breast, lung and other cancers in lab tests and say there is enormous potential for immunotherapies not previously thought to be possible.

Cardiff Universitys cancer findings came from scientists looking for unconventional ways in which the immune system naturally attacks tumours. They found, inside human blood, a T-cell that can scan the body for a threat, such as cancerous cells, and eliminate the danger while leaving healthy cells alone. The team described the work as at an early stage, but exciting.

T-cell cancer therapies are where immune cells are removed, modified and returned to the patients blood to seek and destroy cancer cells. The most widely-used, known as CAR-T, is personalised to the patient but combats only a handful of cancers and has not been successful in eliminating solid tumours - which account for the vast majority of cancers.

The Cardiff teams discovery involves a new type of T-cell receptor (TCR), which recognises a molecule present on the surface of a wide range of cancer cells as well as in many of the bodys normal cells and is, remarkably, able to distinguish between the two. In tests, T-cells equipped with the new TCR killed lung, skin, blood, colon, breast, bone, prostate, ovarian, kidney and cervical cancer cells.

Professor Andrew Sewell, the lead author on the study and an expert in T-cells from Cardiff Universitys School of Medicine, said it was highly unusual to find a TCR with such broad cancer specificity, raising the prospect of universal cancer therapy.

Prof Sewell said: We hope this new TCR may provide us with a different route to target and destroy a wide range of cancers in all individuals. Current TCR-based therapies can only be used in a minority of patients with a minority of cancers.

Cancer-targeting via MR1-restricted T-cells is an exciting new frontier - it raises the prospect of a one-size-fits-all cancer treatment; a single type of T-cell that could be capable of destroying many different types of cancers across the population. Previously nobody believed this could be possible.

Further experiments and safety testing are now underway, with the hope of trialling this new approach in patients towards the end of 2020. Prof Sewell added: There are plenty of hurdles to overcome; however, if this testing is successful, then I would hope this new treatment could be in use in patients in a few years time.

Cancer is the leading cause of all avoidable deaths in the UK. Breast cancer is the most common, followed jointly by prostate and lung cancer and then by bowel cancer. Obesity is now a bigger cause than smoking of some cancers, namely bowel, kidney, liver and ovarian cancer.

Sorry Mom and Dad: It turns out you might not have been exaggerating when you told us your children made your hair turn gray.

Stress may play a key role in just how quickly hair goes from colored to ashen, a study published this past week in the journal Nature suggests.

Scientists have long understood some link is possible between stress and gray hair, but this new research from Harvard University in Massachusetts more deeply probes the exact mechanisms at play.

The researchers initial tests looked closely at cortisol, the stress hormone that surges in the body when a person experiences a fight or flight response.

Its an important bodily function, but the long-term presence of heightened cortisol is linked to a host of negative health outcomes.

But the culprit ended up being a different part of the bodys fight or flight response the sympathetic nervous system.

These nerves are all over the body, including making inroads to each hair follicle, the researchers reported.

Chemicals released during the stress response specifically norepinephrine causes pigment producing stem cells to activate prematurely, depleting the hairs reserves of color.

The detrimental impact of stress that we discovered was beyond what I imagined, Ya-Chieh Hsu, PhD, a lead study author and an associate professor of stem cell and regenerative biology at Harvard, said in a press release. After just a few days, all of the pigment-regenerating stem cells were lost. Once theyre gone, you cant regenerate pigments anymore. The damage is permanent.

But stress isnt the only or even the primary reason that most people get gray hair.

In most cases, its simple genetics.

Gray hair is caused by loss of melanocytes (pigment cells) in the hair follicle. This happens as we age and, unfortunately, there is no treatment that can restore these cells and the pigment they produce, melanin, Dr. Lindsey A. Bordone, a dermatologist at ColumbiaDoctors and an assistant professor of dermatology at Columbia University Medical Center in New York, told Healthline. Genetic factors determine when you go gray. There is nothing that can be done medically to prevent this from happening when it is genetically predetermined to happen.

That doesnt mean environmental factors such as stress dont play a role.

Smoking, for instance, is a known risk factor for premature graying, according to a 2013 study. So kick the habit if you want to keep that color a little longer.

Other contributing factors to premature graying include deficiencies in protein, vitamin B-12, copper, and iron as well as aging due in part to an accumulation of oxidative stress.

That stress is prompted by an imbalance between free radicals and antioxidants in your body that can damage tissue, proteins, and DNA, Kasey Nichols, NMD, an Arizona physician and a health expert at Rave Reviews, told Healthline.

And some degree of oxidative stress is a natural part of life.

We would expect increasing gray hair as we advance in age, and we see about a 10 percent increase in the chance of developing gray hair for every decade after age 30, Nichols said.

Changes you can pursue to delay premature grays include eating a diet high in omega-3 fatty acids such as walnuts and fatty fish, not spending too much time in the skin-damaging and hair-damaging ultraviolet light of the sun, and taking vitamin B-12 and vitamin B-6 supplements.

That said, if you are going gray prematurely, it wouldnt hurt to go have a checkup just in case natural genetic factors arent the sole culprit.

The new Harvard research is only a mouse study, so replicating the same results in a human study would be necessary to strengthen the findings.

But the Harvard research has implications far beyond graying hair, with the hair color change merely one obvious sign of other internal changes as a result of prolonged stress.

By understanding precisely how stress affects stem cells that regenerate pigment, weve laid the groundwork for understanding how stress affects other tissues and organs in the body, said Hsu. Understanding how our tissues change under stress is the first critical step towards eventual treatment that can halt or revert the detrimental impact of stress.

Might that also mean someday halting and reverting the march of premature gray hair? Its too soon to tell.

We still have a lot to learn in this area, Hsu said.

If you havent chanced upon a gua sha stone facial or a jade roller video on your social media, are you even on it? The ancient Chinese technique of face massaging is gaining traction thanks to beauty bloggers sharing their basic kneads. If you have stumbled upon these videos but have no clue whats going on, read on. Dermatologist Dr Nirupama Parwanda says that the basics come from traditional Chinese wisdom: improper blood circulation and stagnant blood flow is one of the main reasons behind various diseases. To improve circulation and drain toxins, you can try jade rollers and gua sha an alternative therapy that involves massaging your skin using special tools. Parwanda says, Our bodies have a source of energy known as chi flowing through it. And to ensure good health and prosperity, we must balance it. Dr Rinky Kapoor, dermatologist and dermato-surgeon, explains, Both rollers and gua sha are made of stones such as quartz, jade, rose quartz and amethyst known for their healing properties. Gua sha is also known as coining, skin scrapping or pressure stroking. FLOW AND GLOWBoth work on the principle of improving blood flow under the skin and enhancing lymphatic drainage. This helps carry the oxygen to the skin cells, which in turn makes the skin tissues healthy, and reduces fine lines and wrinkles. Parwanda says that gua sha is also called natural botox as it helps in controlling signs of ageing. The proven benefits are: pain reduction in muscles and joints; reduction in perimenopause symptoms like anxiety, insomnia, hot flashes; improved blood circulation, removal of toxins. It also treats musculoskeletal disorders and reduces wrinkles.

TOO GOOD TO BE TRUE?Kapoor cautions that just looking at videos online doesnt mean you know the proper way to use it. You need to follow the process to reap the maximum benefits. Also, theres not one simple process for both jade roller and gua sha. Think of it as driving while the basics of accelerator, brake and clutch remain the same, driving styles are different, she says. Start both facials from the neck and then move upwards and with upward strokes. Rollers are simpler to use as you can just start massaging on the outward and upward direction from one point, except for the neck, where the massaging motion is downwards. Gua sha facials require more technique. Tip: you can learn from a practitioner.

Roll play: Jade rollers and gua sha stone are making waves in skincare - Times of India

Marie Antoinette's hair suddenly turned white before the ill-fated French queen was taken to the guillotine to have her head chopped off, according to some historical accounts.

More modern reports refer to hair turning prematurely white in survivors of bomb attacks during World War II, while an Australian airline pilot saw his hair go grey in the months after landing a plane following a failure of all four engines in the early 1980s.

While there's been plenty of anecdotal evidence suggesting premature greying can be caused by extreme stress -- whether this is true and how this happens isn't widely understood.

Now, Harvard University scientists think they have the answer -- at least in mice.

The group of researchers believe it's down to the animal's sympathetic nervous system -- which is best known for activating our "fight or flight" response to danger, they say.

"Under stress, our sympathetic nerve becomes highly activated," said Ya-Chieh Hsu, associate professor of stem cell and regenerative biology at Harvard, in an email. "And actually, activation of the sympathetic nervous system under stress is supposed to be a good thing."

Its activation triggers the "fight or flight" response through the neurotransmitter norepinephrine, or noradrenaline, explained Hsu, a senior author of the study published Wednesday in the scientific journal Nature. "Noradrenaline raises our heartbeat and allows us to react quickly to danger without having to think about it," he said.

"However, it is the same noradrenaline that turns out to be bad for melanocyte stem cells at a high level, and triggers their loss."

Melanocyte stem cells are found in hair follicles and determine hair colour. In people, the pool of these cells deplete as they age, turning hair grey as pigment depletes. Their loss from excessive noradrenaline could be causing this to happen prematurely, the team suggest.

Loss of pigment

The team had thought that acute stress might trigger an immune attack on pigment-producing stem cells or that the blame lied with the hormone cortisol because cortisol levels are elevated under stress. Hsu said they went through many different possibilities before focusing on the sympathetic nervous system.

"We were really surprised to find that it was the culprit, because it is normally seen as a beneficial system, or at least transient and reversible," she said.

The team put mice under three different types of stress through what Hsu described as established standard protocols. These included a single injection of a chemical to activate the mouse's pain fiber, cage tilting and rapid changes between light and dark.

Changes were observed in all mice but there was some variability, with white hair only coming out after all the stem cells are gone.

"Some hair follicles have reduced levels of melanocyte stem cells so they can still make pigment, while others have lost all stem cells and can't make pigment anymore, so the hair becomes white," she said.

Pigment-producing stem cells and the sympathetic nervous system are very similar in mice and humans, explained Hsu who was hopeful that the mechanisms would be related. But future studies would be needed to provide definitive evidence, she said.

"Everyone has an anecdote to share about how stress affects their body, particularly in their skin and hair the only tissues we can see from the outside," Hsu said in a news release.

"We wanted to understand if this connection is true, and if so, how stress leads to changes in diverse tissues. Hair pigmentation is such an accessible and tractable system to start with and besides, we were genuinely curious to see if stress indeed leads to hair greying."

Hsu said the findings may also help shed light on the effects of stress on various organs and tissues, and pave the way for new studies that seek to modify or block the damaging effects of stress.

In an accompanying article, Shayla Clark and Christopher Deppmann, researchers from the Neuroscience Graduate Program at the University of Virginia, who were not involved in the study, said it was interesting to consider what possible evolutionary advantage might be conferred by stress-induced greying.

"Because grey hair is most often linked to age, it could be associated with experience, leadership and trust. Perhaps an animal that has endured enough stress to 'earn' grey hair has a higher place in the social order than would ordinarily be conferred by that individual's age," they wrote.

Everyone sheds about 100 hairs each day as part of the normal hair growth cycle, but excess loss is usually a distressing development.(iStock)

Hair loss is typically considered the domain of aging men, but this equal-opportunity condition which has many causes can affect virtually anyone.

Alopecia is the medical term for hair loss, and it doesnt only happen on the scalp. Some illnesses and medications can trigger balding over the entire body, though genetics account for most cases on the head, according to theCleveland Clinic.

PARTY DRUG MDMA A STEP CLOSER TO LEGALIZATION FOR PTSD THERAPY

Everyone sheds about 100 hairs each day as part of the normal hair growth cycle, but excess loss is usually a distressing development. Americans spend more than $3.5 billion each year trying to treat it, according to theAmerican Hair Loss Association.

Most peoples hair grows about a half-inch per month, and about 90 percentof your hair is actively growing at any given time, with the other 10 percentin dormant phase. After two or three months, this dormant hair falls out and its follicles begin growing new hair as other follicles begin a dormant phase.

Shedding hair is different from hair loss, when a hair falls out and doesnt grow back. People often shed hair during stressful events, such aschildbirth, a breakup or divorce or during times of grief.

It still doesnt feel good, and it takes the hair [awhile] to reach a certain length where you perceive its presence, said Doris Day, a board-certified dermatologist New York City and an attending physician at Lenox Hill Hospital, also in New York. So it feels like a hair loss, but its not a hair loss.

Aside from heredity, noticeable hair loss can be caused by wide variety of factors, including:

Harsh hairstyles or treatments: Hairstyles that consistently use rubber bands, rollers or barrettes, or pull hair into tight styles such as cornrows, can inflame and scar hair follicles. So can incorrectly used chemical products such as dyes, bleaches, straighteners or permanent wave solutions. Depending on the degree of damage, resulting hair loss can be permanent.

Hormone imbalances: In women, hormonal shifts from birth control pills,pregnancy, childbirth, menopause or hysterectomy can induce more hair follicles than normal to enter the dormant phase.

Illness or surgery: The stress from sickness or surgery may prompt the body to temporarily cease nonessential tasks such as hair production. Specific conditions can also trigger it, including thyroid disorders,syphilis, iron deficiency,lupusor severe infection. An autoimmune condition called alopecia areata, which has no cure, causes rapid body-wide hair loss.

Medications and vitamins: Cancer chemotherapy, which attacks hair follicles in its attempt to kill all fast-growing cells around the body, is a well-known reason for hair loss. Other medications side effects include hair shedding as well, such as some that treat high blood pressure andgout(a painful joint condition caused by a buildup of uric acid). Excessive levels of vitamin A also contribute.

Nutritional deficits: Heavy dieting or eating disorders such asbulimiaandanorexiacan temporarily stun hair follicles to cease growth. This can also occur from insufficient protein, vitamin or mineral intake.

Aging: A natural effect of growing older is slowed hair growth.

Women usually dont go completely bald, but lose hair on the top of the head or the temples. Men tend to lose hair on their temples, and are more likely than women to go completely bald, Day said.

Dermatologists will examine the persons scalp and take a history of medical or stressful events to see whats been going on in their life and their world, Day said.

HELICOPTER-SHARING APP BLADE PAIRS WITH NYU LANGONE TO SPEED TRANSPLANT ORGANS

The dermatologist may take a biopsy a small patch of skin that includes the hair follicle and send it to a pathologist to determine if an autoimmune disease, such as lupus, is the cause of the hair loss.

Examining the hair and follicle can also determine whether someone has a bacterial or fungal infection, Day said.

Hair loss remedies range from the mild to the extreme and the inexpensive to the costly. Much depends on how much hair is gone and how high a priority it is to mask its absence or replace it.

According to the Cleveland Clinic, treatments include:

Hair weaves or wigs: Typically expensive, wigs and hair weaves either completely cover the head or add to existing hair, restoring the appearance of a full head of hair. They are especially practical for cancer patients and those whose hair loss is temporary.

Topical creams and lotions: Over-the-counter minoxidil (also known as the brand name Rogaine) can restore some hair growth, especially in those with hereditary hair loss. It is applied directly to the scalp. Prescription-strength finasteride (Propecia) comes in pill form and is only for men. According to theAmerican Academy of Family Physicians(AFP), it may take up to six months to tell if these medications are working.

Anti-inflammatory medications: Prescription steroid-based creams or injections can calm follicles damaged or inflamed by harsh chemicals or excessive pulling.

Surgery: Men tend to be better candidates for surgical hair-replacement techniques because their hair loss is often limited to one or two areas of the scalp. Procedures include grafting, which transplants from one to 15 hairs per disc-shaped graft to other locations. Scalp reduction removes bald skin from the scalp so hair-covered scalp can be stretched to fill in the bald areas. Side effects include swelling, bruising and headaches.

Hair-growth laser treatment can also help stimulate hair follicles and improve growth, Day said. People often see results when they combine laser treatment with another intervention, she said. Treatments range in price from $30 and up for Rogaine to about $3,000 for laser treatment, she added.

According to theNational Institute of Arthritis and Musculoskeletal and Skin Diseases(NIAMSD), alternative therapies may not help hair regrow and many are not supported by medical research. However, other treatments that reportedly improve alopecia areata include Chinese herbs, acupuncture, zinc and vitamin supplements, evening primrose oil and aroma therapy.

Viviscal, a natural supplement, has also shownmore hair growthin men compared to those who took fish extract in clinical trials, Day said.

The NIAMSD recommends discussing any alternative treatments with physicians before use.

The drug Tofacitinib is approved to treat adults witharthritis, but a growing number of cases suggest that it can also treat alopecia universalis, a condition in which people lose all of the hair on their body because theirimmune systemattacks hair follicles,Live Science previously reported.

The finding occurred after doctors prescribed a 25-year-old man with alopecia universalis the drug because they had heard it had treated a similar condition in mice,according to a statement from Yale University. After three months of treatment, the man had completely regrown the hair on his scalp, and he had visible eyebrows, eyelashes, facial hair, as well as hair elsewhere on his body.

Its exciting, said Day, who did not treat this particular patient. There seems to be a real effect here.

Its unclear how Tofacitinib (brand name Xeljanz) works, but researchers hope to determine its mechanism soon. This data may help them learn which biological pathways lead to hair loss.

There are now clinical trials taking place around the country to test the safety and efficacy of the drug for hair loss conditions. One such study lasting 3 months gave Tofacitinib to 66 people with alopecia areata (an immune system condition that causes hair to fall out in patches). Half of the people regrew some hair, and one-third had more than 50 percentof the hair on their scalp grow back, according to the 2016 study, published in the journalJCI Insight.

However, researchers are still working to determine the best dose needed, whether the results are lasting, and whether they can develop a topical form of the drug, Day said. She added that patients should be aware that Tofacitinib has side effects. Its already associated with an increased risk of serious infections, as well as stomach and intestinal tears, according to Pfizer, the manufacturer.

Besides investigating Tofacitinib, researchers are also looking at ways to clone hair or use stem cell therapy to treat alopecia, Day said.

Alopecia: What causes the hair loss condition? - foxwilmington.com

With so many groundbreaking medical advances being revealed to the world every single day, you would imagine there would be some advancement on the plethora of many female-prevalent diseases (think female cancers, Alzheimer's, depression, heart conditions etc.) that women are fighting every single day.

For Anna Villarreal and her team, there frankly wasn't enough being done. In turn, she developed a method that diagnoses these diseases earlier than traditional methods, using a pretty untraditional method in itself: through your menstrual blood.

Getting from point A to point B wasn't so easy though. Villarreal was battling a disease herself and through that experience. I wondered if there was a way to test menstrual blood for female specific diseases," she says. "Perhaps my situation could have been prevented or at least better managed. This led me to begin researching menstrual blood as a diagnostic source. For reasons the scientific and medical community do not fully understand, certain diseases impact women differently than men. The research shows that clinical trials have a disproportionate focus on male research subjects despite clear evidence that many diseases impact more women than men."

There's also no denying that gap in women's healthcare in clinical research involving female subjects - which is exactly what inspired Villarreal to launch her company, LifeStory Health. She says that, with my personal experience everything was brought full circle."

There is a challenge and a need in the medical community for more sex-specific research. I believe the omission of females as research subjects is putting women's health at risk and we need to fuel a conversation that will improve women's healthcare.,"

-Anna Villarreal

Her brand new biotech company is committed to changing the women's healthcare market through technology, innovation and vocalization and through extensive research and testing. She is working to develop the first ever, non-invasive, menstrual blood diagnostic and has partnered with a top Boston-area University on research and has won awards from The International Society for Pharmaceutical Engineering and Northeastern University's RISE.

How does it work exactly? Proteins are discovered in menstrual blood that can quickly and easily detect, manage and track diseases in women, resulting in diseases that can be earlier detected, treated and even prevented in the first place. The menstrual blood is easy to collect and since it's a relatively unexplored diagnostic it's honestly a really revolutionary concept, too.

So far, the reactions of this innovative research has been nothing but excitement. The reactions have been incredibly positive." she shares with SWAAY. Currently, menstrual blood is discarded as bio waste, but it could carry the potential for new breakthroughs in diagnosis. When I educate women on the lack of female subjects used in research and clinical trials, they are surprised and very excited at the prospect that LifeStory Health may provide a solution and the key to early detection."

To give a doctor's input, and a little bit more of an explanation as to why this really works, Dr. Pat Salber, MD, and Founder of The Doctor Weighs In comments: researchers have been studying stem cells derived from menstrual blood for more than a decade. Stem cells are cells that have the capability of differentiating into different types of tissues. There are two major types of stem cells, embryonic and adult. Adult stem cells have a more limited differentiation potential, but avoid the ethical issues that have surrounded research with embryonic stem cells. Stem cells from menstrual blood are adult stem cells."

These stem cells are so important when it comes to new findings. Stem cells serve as the backbone of research in the field of regenerative medicine the focus which is to grow tissues, such as skin, to repair burn and other types of serious skin wounds.

A certain type of stem cell, known as mesenchymal stem cells (MenSCs) derived from menstrual blood has been found to both grow well in the lab and have the capability to differentiate in various cell types, including skin. In addition to being used to grow tissues, their properties can be studied that will elucidate many different aspects of cell function," Dr. Salber explains.

To show the outpour of support for her efforts and this major girl power research, Villarreal remarks, women are volunteering their samples happily report the arrival of their periods by giving samples to our lab announcing de-identified sample number XXX arrived today!" It's a far cry from the stereotype of when it's that time of the month."

How are these collections being done? Although it might sound odd to collect menstrual blood, plastic cups have been developed to use in the collection process. This is similar to menstrual products, called menstrual cups, that have been on the market for many years," Dr. Salber says.

Equally shocking and innovative, this might be something that becomes more common practice in the future. And according to Dr. Salber, women may be able to not only use the menstrual blood for early detection, but be able to store the stem cells from it to help treat future diseases. Companies are working to commercialize the use of menstrual blood stem cells. One company, for example, is offering a patented service to store menstrual blood stem cells for use in tissue generation if the need arises."

The first symposium of the South West Brain Tumour Centre was held on Thursday at Derriford Hospital in Plymouth. During a fascinating and very well attended event, topics covered included the mechanism of tumour development, new drug targets, new biomarkers and brain tumour imaging. The South West Brain Tumour centre is of course one of the UK Centres of Excellence funded by Brain Tumour Research.

A really big cancer wide story this week is here Immune discovery 'may treat all cancer' applicable to some solid tumours but not yet brain it really shows the direction of travel toward immunotherapy I have recommended this book before but if interested please do read The Breakthrough by Charles Graeber it is available on Amazon and you can read reviews here - http://www.charlesgraeber.com.Researchers uncover novel drug target for glioblastoma by revealing a cellular pathway that appears to contribute to glioma stem cell spread and proliferation. This pathway shows that glioma stem cells ability to access key nutrients in their surrounding microenvironment is integral for their maintenance and spread. Finding a way to interrupt this feedback loop will be important for treating glioblastoma.

An intelligent molecule could significantly extend the lives of patients with glioblastoma, research finds. The molecule, called ZR2002, which can be administered orally and is capable of penetrating the blood-brain barrier, could delay the multiplication of glioblastoma stem cells resistant to standard treatment. According to scientists in the Metabolic Disorders and Complications Program at the Research Institute of the McGill University Health Centre (RI-MUHC) the ZR2002 molecule is designed to kill two birds with one stone: on top of attacking the tumour, it destroys its defence system.

Researchers find clues to drug resistance in medulloblastoma subtype.US scientists have identified specific types of cells that cause targeted treatment to fail in a subtype of medulloblastoma. They found while the majority of cells responded to treatment, diverse populations within the tumour continue to grow leadingto treatment resistance. They concluded that the diversity of cells within tumours allow them to become rapidly resistant to precisely targeted treatments," and that due to this tumour cell diversity, molecularly precise therapies should be used in combinations to be effective."

Nanoparticles deliver 'suicide gene' therapy to paediatric brain tumours growing in mice So-called "suicide genes" have been studied and used in cancer treatments for more than 25 years. Researchers report here that a type of biodegradable, lab-engineered nanoparticle they fashioned can successfully deliver a ''suicide gene'' to paediatric brain tumour cells implanted in the brains of mice.

According to a study that uncovers an unexpected connection between gliomas and neurodegenerative diseases a protein typically associated with neurodegenerative diseases like Alzheimers might help scientists explore how gliomas become so aggressive. The new study, in mouse models and human brain tumour tissues, was published in Science Translational Medicine and found a significant expression of the protein TAU in glioma cells, especially in those patients with better prognoses. Patients with glioma are given a better prognosis when their tumour expresses a mutation in a gene called isocitrate dehydrogenase 1 (IDH1). In this international collaborative study led by the Instituto de Salud Carlos III-UFIEC in Madrid, Spain, those IDHI mutations stimulated the expression of TAU. Then, the presence of TAU acted as a brake for the formation of new blood vessels, which are necessary for the aggressive behaviour of the tumours.

'Innovative research award' helps Colorado scientists block brain cancer escape routes Cancers used to be defined by where they grow in the body - lung cancer, skin cancer, brain cancer, etc. But work in recent decades has shown that cancers sharing specific genetic changes may have more in common than cancers that happen to grow in an area of the body. For example, lung cancers, skin cancers, and brain cancers may all be caused by mutation in a gene called BRAF. Drugs targeting BRAF have changed the treatment landscape for melanoma, an aggressive form of skin cancer, and are also in use against lung cancers and brain cancers with BRAF mutations. It is really worth clicking through to read more on this and the ultimate goal of identifying new potential targets for combination therapy and new agents that could be added to BRAF inhibiting drugs in brain cancer to keep the cancer from developing resistance.

What I Learned About Marriage as a Survivor of Abuse - SWAAY

It is not uncommon to hear people say that stress causes one's hair to gray. Many famous American Presidents such as George W. Bush and Barrack Obama grayed drastically by the end of their taxing presidencies. Yet, the real exact behind the process has eluded scientists... Until now.

Researchers from Harvard University have finally uncovered the precise mechanism that causes graying using mice. Stress triggers nerves that are closely involved in the fight-or-flight response. This, in turn, causes irreversible damage to pigment-regenerating stem cells that are found in the hair follicles.

"We wanted to understand if this connection is true, and if so, how stress leads to changes in diverse tissues. Hair pigmentation is such an accessible and tractable system to start with and besides, we were genuinely curious to see if stress indeed leads to hair graying," said Chieh Hsu, senior author of the study, in a statement.

Stress affects the entire body. Therefore, the researchers had to first ascertain which system of the body was responsible for linking hair colour to stress. The first hypothesises that was formulated was that stress leads to an immune attack against pigment-producing cells. However, the scientists found that in spite of lacking immune cells, some mice continued to exhibit graying of hair. This prompted the researchers to assess the hormone cortisolwhich also did not prove to be the real culprit.

Citing the increase in the levels of cortisol as a response to stress, the team assumed that hormone played a role in the graying processonly to learn that it did not. "But surprisingly, when we removed the adrenal gland from the mice so that they couldn't produce cortisol-like hormones, their hair still turned gray under stress," Hsu said.

Following the striking down of immune response and cortisol levels from a list of possible causes, the researchers began systematically eliminating the various possibilities. Finally, they set their sights on the sympathetic nerve system, which is attributed to controlling the body's fight-or-flight response.

Sympathetic nerves branch into every hair follicle on the skin. What the authors discovered was that stress promotes the release of the chemical norepinephrine by these nerves. The released chemical is absorbed by the pigment-regenerating stem cells that are situated nearby.

Specific stem cells within the hair follicle act as a reservoir of pigment-generating cells. During the regeneration of hair, some of the stem cells are converted into pigment-producing cells that give hair its color.

The team found that the norepinephrine produced by the sympathetic nerves causes uncontrolled activation of the stem cells. All the stem cells now turn into pigment-producing cells, which in turn lead to the premature depletion of the reservoir.

"Acute stress, particularly the fight-or-flight response, has been traditionally viewed to be beneficial for an animal's survival. But in this case, acute stress causes permanent depletion of stem cells," said Bing Zhang, lead author of the study. Therefore, the study highlights the damaging side effects of a generally beneficial evolutionary response that is often considered vital for survival.

In order to make the connection between stress and graying, the researchers began with a complete-body response and gradually focussed on individual organ systems, cell-to-cell interactions, and finally, down to molecular dynamics. A range of research tools was employed for this process, including techniques to manipulate cell receptors, nerves and organs.

For the intrinsic study that focussed on various macro and micromechanisms of the body, the researchers collaborated with scientists across various disciplines. One such collaborator was Isaac Chiu, assistant professor of immunology at Harvard Medical School.

Pointing out that the current study learned beyond the various known capacities of neurons, Chiu said, "With this study, we now know that neurons can control stem cells and their function, and can explain how they interact at the cellular and molecular level to link stress with hair graying."

The researchers say that these findings may further the understanding of broad-ranging effects of stress on various types of tissues and organs. This knowledge will provide a new foundation to study and develop ways to block or modify the effects of stress.

"Understanding how our tissues change under stress is the first critical step towards eventual treatment that can halt or revert the detrimental impact of stress. We still have a lot to learn in this area," concluded Hsu.

Scientists zero in on exact reason behind the link between stress and graying of hair - International Business Times, Singapore Edition

When Marie Antoinette was captured during the French Revolution, her hair reportedly turned white overnight. In more recent history, John McCain experienced severe injuries as a prisoner of war during the Vietnam War and lost color in his hair.

For a long time, anecdotes have connected stressful experiences with the phenomenon of hair graying. Now, for the first time, Harvard University scientists have discovered exactly how the process plays out: stress activates nerves that are part of the fight-or-flight response, which in turn cause permanent damage to pigment-regenerating stem cells in hair follicles.

The study, published in Nature, advances scientists knowledge of how stress can impact the body.

Everyone has an anecdote to share about how stress affects their body, particularly in their skin and hair the only tissues we can see from the outside, said senior author Ya-Chieh Hsu, the Alvin and Esta Star Associate Professor of Stem Cell and Regenerative Biology at Harvard. We wanted to understand if this connection is true, and if so, how stress leads to changes in diverse tissues. Hair pigmentation is such an accessible and tractable system to start with and besides, we were genuinely curious to see if stress indeed leads to hair graying.

Narrowing down the culprit

Because stress affects the whole body, researchers first had to narrow down which body system was responsible for connecting stress to hair color. The team first hypothesized that stress causes an immune attack on pigment-producing cells. However, when mice lacking immune cells still showed hair graying, researchers turned to the hormone cortisol. But once more, it was a dead end.

Stress always elevates levels of the hormone cortisol in the body, so we thought that cortisol might play a role, Hsu said. But surprisingly, when we removed the adrenal gland from the mice so that they couldnt produce cortisol-like hormones, their hair still turned gray under stress.

After systematically eliminating different possibilities, researchers honed in on the sympathetic nerve system, which is responsible for the bodys fight-or-flight response.

Sympathetic nerves branch out into each hair follicle on the skin. The researchers found that stress causes these nerves to release the chemical norepinephrine, which gets taken up by nearby pigment-regenerating stem cells.

Permanent damage

In the hair follicle, certain stem cells act as a reservoir of pigment-producing cells. When hair regenerates, some of the stem cells convert into pigment-producing cells that color the hair.

Researchers found that the norepinephrine from sympathetic nerves causes the stem cells to activate excessively. The stem cells all convert into pigment-producing cells, prematurely depleting the reservoir.

When we started to study this, I expected that stress was bad for the body but the detrimental impact of stress that we discovered was beyond what I imagined, Hsu said. After just a few days, all of the pigment-regenerating stem cells were lost. Once theyre gone, you cant regenerate pigment anymore. The damage is permanent.

The finding underscores the negative side effects of an otherwise protective evolutionary response, the researchers said.

Acute stress, particularly the fight-or-flight response, has been traditionally viewed to be beneficial for an animals survival. But in this case, acute stress causes permanent depletion of stem cells, said postdoctoral fellow Bing Zhang, the lead author of the study.

Answering a fundamental question

To connect stress with hair graying, the researchers started with a whole-body response and progressively zoomed into individual organ systems, cell-to-cell interaction and, eventually, all the way down to molecular dynamics. The process required a variety of research tools along the way, including methods to manipulate organs, nerves, and cell receptors.

To go from the highest level to the smallest detail, we collaborated with many scientists across a wide range of disciplines, using a combination of different approaches to solve a very fundamental biological question, Zhang said.

The collaborators included Isaac Chiu, assistant professor of immunology at Harvard Medical School who studies the interplay between nervous and immune systems.

We know that peripheral neurons powerfully regulate organ function, blood vessels, and immunity, but less is known about how they regulate stem cells, Chiu said.

With this study, we now know that neurons can control stem cells and their function, and can explain how they interact at the cellular and molecular level to link stress with hair graying.

The findings can help illuminate the broader effects of stress on various organs and tissues. This understanding will pave the way for new studies that seek to modify or block the damaging effects of stress.

By understanding precisely how stress affects stem cells that regenerate pigment, weve laid the groundwork for understanding how stress affects other tissues and organs in the body, Hsu said. Understanding how our tissues change under stress is the first critical step towards eventual treatment that can halt or revert the detrimental impact of stress. We still have a lot to learn in this area.

The study was supported by the Smith Family Foundation Odyssey Award, the Pew Charitable Trusts, Harvard Stem Cell Institute, Harvard/MIT Basic Neuroscience Grants Program, Harvard FAS and HMS Deans Award, American Cancer Society, NIH, the Charles A. King Trust Postdoctoral Fellowship Program, and an HSCI junior faculty grant.

Researchers uncover link between the nervous system - Tdnews

The folk wisdom that tension and anxietycan turn your hair gray appears to be scientifically valid, according to a new study in mice.

Researchers found that the cascade of fight-or-flight hormones precipitated by stressful events eliminated many of the stem cells responsible for hair color in mice.

This group of stem cells, which have the ability to turn into many types of cells, are found in the base of each hair follicle and give hair its color by becoming pigment producing cells called melanocytes which produce brown, black, red and yellow colors in hair and skin.

The researchers found that stress causes these stem cells to convert into melanocytes en masse, only to drift away from the follicle and break down. This depletes the follicles supply and can mean the next time it makes a hair there arent enough stem cells to give it a color, producing an unpigmented gray or white hair.

After a series of experiments, the researchers narrowed down the culprit behind the destruction of the follicles pigment factories to the fight-or-flight hormone noradrenaline, or norepinephrine which is released by whats called the sympathetic nervous system.

Normally, the sympathetic nervous system is an emergency system for fight or flight, and it is supposed to be very beneficial or, at the very least, its effects are supposed to be transient and reversible, biologist Ya-Chieh Hsu, who led the study, told the New York Times.

This is the first scientific study explicitly linking stress and graying, according to Hsu.

The experiments in mice found that acute stress could wipe out all the melanocyte stem cells in just five days. Early tests suggest the same might be true in humans: When the researchers exposed human melanocyte stem cells to noradrenaline they too differentiated in large numbers.

Hsu told the Guardian the same response may drive age-related greying. There are definitely shared responses between how the melanocyte stem cells respond to stress and how they respond to aging, she said. You essentially lose the stem cell pool in aging as well.

Developing the research into an effective treatment to end graying hair will likely take years, but revealing the mechanism at work could advance our understanding of how stem cells are lost elsewhere in the body one of the hallmarks of the physical decline that accompanies aging.

This is certainly one implication that Im particularly excited about, biologist Christopher Deppmann, who was not involved in the research, told the Guardian. I believe that we have only scratched the surface of whether and how stress and fight-or-flight mechanisms deplete other stem cell populations. Whether or not this is the cause of premature aging remains to be determined, but I wouldnt bet against it.

Like any good study, it opens up at least as many questions as it answers, he added. But it may represent an important stepping stone toward rationalizing and developing pharmaceutical fountains of youth.

China started off 2019 by completing the first soft landing on the far side Earths moon. It was a monumental achievement, and the months since the mission arrived at the Moon have been filled with interesting discoveries, including the discovery of a strange gel-like substance around a lunar crater.

Now, as China celebrates the one year anniversary of the Change 4 lander and Yutu-2 rover arriving at the Moon, the countrys space group has released a wealth of data, including some never-before-seen images of the far side of Earths tiny neighbor.

The images some of which benefit from post-processing at the hands of talented scientists and enthusiasts show the Moons least-studied face in stunning detail.

The Change 4 mission included a lunar lander and a rover that explored the Moons surface. Because of the nature of day and night on the Moon, the instruments are put into a sleep mode when the far side falls into shadow, waking back up when the sun shines again.

China, which has historically lagged behind countries like the United States and Russia when it comes to space exploration, is rapidly catching up. Landing on the far side of the Moon is no easy task, and the countrys space agency pulled it off with flying colors. Going forward, China is poised to be a major player in space exploration and has even discussed the possibility of setting up semi-permanent bases on the lunar surface.

You can browse through a massive collection of these new images via a handy Google Drive link, or sift through the raw images via CNSAs web portal.

You either swear by facial oils or are skeptical of all the fanfare and its myriad of purported benefits. In recent years, facial oils have become a booming skincare category, taking up prominent shelf space. There are all kinds of facial oils you can choose from with ingredients like rosehip, marula and jojoba. They are also said to boast a bevy of skincare benefits like brightening, calming inflammation and minimizing the look of fine lines and wrinkles. Despite their popularity, theres also some confusion around face oils. Will they clog pores? Do they replace your moisturizer? Do you even actually need one? To help make sense of it all, we enlisted the help of two experts to break it all down, plus, the best facial oils for every skin concern.

The purpose of a facial oil is to provide moisture to the skins surface and serve as a protective layer against environmental aggressors, says Dr. Monica Li, a Vancouver-based dermatologist and clinical instructor in the department of dermatology and skin science at the University of British Columbia. Facial oils both act like an emollient (filling in the gaps between skin cells to strengthen the outer layer)and an occlusive agent (sealing water in at the skin surface), explains Li.

Our skin produces natural oilsknown as sebumwhich help retain water within the skin surface. A facial oil is basically added protection, helping supplement the oils the skin already produces and maintain a robust skin barrier function, says Li.

A face oil can be a game-changer for your skin, says Jennifer Brodeur, a Montreal-based facialist to celebs like Oprah and Michelle Obama, and founder of JB Skin Guru. The right face oil will help with skin homeostasis [its ability to maintain a stable internal environment], as it provides nutrition and hydration to the skin.

Facial oils can be beneficial for everyoneeven oily skin types. A caveat: theres no one-size-fits-all formula. As not all face oils are created equally, its important to know what face oils are right for you, says Brodeur.

Since not all oils are the same, different ones will have different skincare benefits. Beyond its hydrating and nourishing properties, a facial oil can also have anti-inflammatory, antimicrobial and antioxidant benefits, depending on the ingredients and composition, says Li. Brodeur adds: My favourites are those that contain lots of good fatty acids and vitamins. For example, sunflower seed oil, peoni root extract and rosehip seed oil. However, you also need to be mindful of your skin type.

For sensitive skin, Brodeur recommends steering clear of essential oils, especially citrus oils. Essential oils can be very potent, which means they can cause irritation or trigger allergies for sensitive skin. Citrus oils in particular like orange, grapefruit and bergamot can cause photosensitivity, resulting in skin irritation or discolouration. Brodeur also suggests avoiding oils with dye or fragrances.

If you have oily skin, Dr. Li recommends using an oil with a light texture like jojoba or grapeseed that will absorb more easily into the skin and wont clog pores.

For dry skin, look for a facial oil with either oat or argan oil, both of which are known for their soothing and nourishing properties. Mixing two to three drops of the facial oil with a moisturizer will have a compounded hydrating effect, says Li.

Once you choose an oil, apply it on a test spot like on the wrist or behind the ears for at least a week. Keep in mind that these natural oil ingredients may be a source of contact allergens depending on the individual, she adds. Facial oils are still a relatively new category of skincare and more research and clinical studies are l needed, so its best to consult with a board-certified dermatologist if you have any questions or concerns.

The answer will vary depending on who you ask (yes, its that controversial). For the most part, experts agree that you should use a facial oil after your moisturizer as the final step in your skincare routine. Oil sits on water, so it creates a protective layer to prevent water loss, explains Brodeur. However, if your skin is on the drier side, you can apply oil first or even layer with an oil, moisturizer and then oil again. You can even mix a few drops of facial oil into your moisturizer or foundation for a dewy glow.

As a rule of thumb, serums are usually used to target specific skin concerns [such as hyperpigmentation and fine lines and wrinkles], whereas oils are primarily used to nourish and hydrate the skin, says Brodeur, meaning you can use both a serum and a facial oil.

Always apply facial oil on clean skin after youve cleansed. Brodeur recommends using two to three drops and taking the time to massage it into your skin using upward strokes.
