Vibration-induced white finger disease (VWF) is caused by continued use of vibrating hand held machinery (high frequency vibration >50 Hz), and affects tens of thousands of people. New research published in BioMed Central's open access journal Clinical Epigenetics finds that people with a genetic polymorphism (A2191G) in sirtuin1 (SIRT1), a protein involved in the regulation of endothelial NOS (eNOS), are more likely to suffer from vibration-induced white finger disease. VWF (also known...

New research in The FASEB Journal suggests that a protein called SIRT1 responds to excess fat calories in pregnancy by rewriting the histone code leading to infants with fatty-livers and eventual obesity If you are overweight and pregnant, your baby isn't destined to a life of obesity after all, according to a new research report published online in The FASEB Journal. In the report, a team of U.S. scientists show that modifying fat intake during pregnancy to a moderate level is enough to...

Milk Ingredient Protects Against Obesity

Connie K. Ho for redOrbit.com Milk ads have long proclaimed that milk does the body good. Now, there may be research that backs this idea of milk as having particular attributes to boost a healthy body. Researchers found that a natural ingredient in milk can help protect against obesity, even when mice consume foods that are high in fat. The findings, published in the June issue of Cell Metabolism, believe that the milk ingredient is similar to a new type of vitamin. The discovery of NR...

New research reinforces the claim that resveratrol–a compound found in plants and food groups, notably red wine–prolongs lifespan and health-span by boosting the activity of mitochondria, the cell's energy supplier. "The results were surprisingly clear," said David Sinclair, a professor of genetics at Harvard Medical School and the study's senior author. "Without the mitochondria-boosting gene SIRT1, resveratrol does not work." Over the last decade, Sinclair and colleagues...

Findings may settle scientific debate surrounding this chemical found in red wine and other foods National Institutes of Health researchers and their colleagues have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found that resveratrol inhibits certain types of...

(Ivanhoe Newswire) — Treatment that increases brain levels of a crucial regulatory enzyme may slow the loss of brain cells that characterize Huntington´s disease (HD) and other neurodegenerative disorders, according to this study. Increased expression of Sirt1, one of a family of enzymes called sirtuins, in the brain of a mouse model of HD protected against neurodegeneration. They also identified a potential mechanism for this protective effect. "Diseases such as Huntington's,...

Eating Less Improves Brain Function

Calorie restriction activates genes linked to longevity and brain function, according to a new Italian study with mice. The researchers found that overeating may cause brain aging, while eating less turns on a molecule that helps the brain stay young. The discovery could lead to new treatments to keep the brain in a healthy, youthful state without the need for a restrictive diet, the researchers said. Previous studies using animals have found that low calorie diets extend life,...

Scientists Question Resveratrol Longevity Products

   New research suggests that anti-ageing face creams and supplements, that actively use a 'miracle ingredient' commonly found in red wine, are a complete waste of time and money, and do nothing to improve your odds of living a longer life. Resveratrol, which is credited with many of the health benefits of red wine, has become a staple for several beauty companies and is used in numerous products that can fetch prices of up to several hundreds of dollars for just a small...

Research published in the Cancer Cell journal in March was a significant step in knowing the causes of cancer better, especially breast cancer, revealing that the lack or loss of a protein in the cells known as SIRT3, induces the proliferation of this disease and thereby, this protein can be an may be a therapeutic target in the development of effective therapies for cancer. The research was led by Dra. Marcia Haigis of the Harvard Medical School, with the participation of Dr. Arkaitz...
