NEW YORK (Reuters Health) - Long-term high consumption of red and processed meat may increase the risk of cancer in the colon and rectum, a new study shows.

Dr. Michael J. Thun, with the American Cancer Society in Atlanta, and colleagues followed 148,610 adults, average age 63 years, who completed questionnaires in 1982 and again between 1992 and 1993 regarding their diet, exercise, medical history and other lifestyle habits.

By 2001, there were 1667 new cases of colorectal cancer, according to a report in Wednesday's Journal of the American Medical Association.

The participants who consistently ate the most red meat and processed meats had a 50 percent higher rate colorectal cancer than those who ate the least red or processed meat.

Prolonged high consumption of poultry and fish was marginally associated with about a 25 percent lower risk of colon cancer, but not rectal cancer. Read more...

NEW YORK--Will exotic orchids soon be subjected to the same genetic scrutiny as some luxury caviars? That is just one of the coding conundrums that scientists convened at the New York Botanical Garden in the Bronx to discuss on a cloudy mid-April afternoon. [More]

Medical Hypothesis: No small matter: microRNAs - key regulators of cancer stem cells by Qing Ji, David Karnak, Ping Hao, Rongquan Wang and Liang Xu, Int J Clin Exp Med 2010(Mar 12); 3(1): 84-7 [FriendFeed entry][Full text via PMC]. PubMed Abstract:

Emerging evidence demonstrates that both tumor suppressor and oncogenic miRNAs play an essential role in stem cell self-renewal and differentiation by negatively regulating the expression of certain key genes in stem cells. It seems logical that they may also be critical players in cancer stem cells. Though small in size, miRNAs play a key role in the epigenetic regulation of cancer stem cells. Specifically, the imbalance of oncogenic vs. tumor suppressor miRNAs may lead to dysregulation of cancer stem cells, thus causing excessive self-renewal and survival of cancer stem cells, and resistance to chemo/radiotherapy. We postulate that restoring the balance of miRNAs will correct this dysregulation via the direct and simultaneous modulation of downstream stem cell pathways involved in cancer stem cell self-renewal and/or differentiation. The resultant restoration of key regulatory pathways could improve therapeutic response. Restoring tumor suppressor miRNAs and/or inhibiting oncogenic miRNAs may provide a novel molecular therapy for human cancers, potentially via modulating cancer stem cells.

No single area of the body stands alone, everything is linked up. This is why medical specialisation is one of the greatest mistakes that was ever

made.

Viewed from this angle, hardly any two areas are so closely and deeply intertwined as the renal metabolism and the bone metabolism. Thus, it is understandable that weakness in the kidneys must necessarily result in weakness in the bones. The discussion of these interrelations is the

theme of this treatise.

Significance of the kidney as the centre of bone formation:

- The kidney as regulator of the

electrolytes

- The kidney as regulator of the

acid-alkaline balance

- The kidney as the base of anxiety Read more...

Plans by  FDA to Adopt stricter standards for Bioequivalence, Bioavailability for generic drugs could sound trouble for Indian Generic Manufactures. Already most of the smaller companies are finding it difficult to get FDA approval letters. QSR Draft Guidance An industry working group has urged the FDA to consider adopting its guidance to outline quality system requirements (QSR) for bioequivalence and bioavailability testing during drug clinical trials.

There was a recent report in NY times that mentioned about several thousand patients receiving nitroglycerin tablets that were not approved by FDA http://www.nytimes.com/2010/03/27/business/27nitro.html

FDA recently evaluated 2070 human studies conducted between 1996 and 2007. These studies compared the absorption of brand name and generic drugs into a person’s body. These studies were submitted to FDA to support approval of generics. The average difference in absorption into the body between the generic and the brand name was only 2.3%. Some generics were absorbed slightly more, some slightly less. This amount of difference would be expected and acceptable, whether for one batch of brand name drug tested against another batch of the same brand, or for a generic tested against a brand name. In fact, there have been studies in which branded drugs were compared with themselves, as well as with a generic. As a rule, the difference for the generic-to-brand comparison was about the same as the brandto- brand comparison” (www.fda.gov/ Drugs/ResourcesForYou/Consumers/ BuyingUsingMedicineSafely/Under standingGenericDrugs/ucm167991. htm)
