Fish Oil studies analyzed, confirm that Omega-3 fatty acids still matter

Literally hundreds of clinical trials, including some that have gained widespread attention, have been done on the possible benefits of omega-3 fatty acids for the prevention of heart disease - producing conflicting results, varied claims, and frustrated consumers unsure what to believe. A recent analysis done by scientists in the Linus Pauling Institute at Oregon State University, published in the Journal of Lipid Research, has sorted through many of these competing findings, and it helps to explain why so many of the studies seem to arrive at differing conclusions. The review concludes that both fish consumption and dietary omega-3...

Men Who Exercise Have Fast Swim Sperm

Men who are hoping to have children in the future would do well to get to the gym, after a study found exercise could help their sperm to swim faster. Researchers found men who worked out more had faster swimming sperm that was better formed, compared to their sedentary peers. They suggest that exercise promotes healthy hormone levels that create a better environment in the testes for sperm production. The findings, are important because semen quality has dropped overall in the last 50 years. Many factors have been blamed including drinking, smoking, and the rising levels of obesity. The team assessed whether there was any difference...

75% of patients taking popular Blood-Thinners are given wrong dose

Cardiology researchers at the Intermountain Medical Center Heart Institute have found that approximately 75 percent of patients taking two common blood-thinning drugs may be receiving the wrong dosage levels, according to a new study. This could put them at risk for serious problems like uncontrolled bleeding or developing blood clots. Millions of Americans with coronary artery disease take one of the two drugs - clopidogrel (Plavix) and prasugrel (Effient) - to prevent harmful blood clots that can cause a stroke or heart attack. Current guidelines recommend that all patients take the same standardized dose. But in this new study of...

How Anti Aging Cosmetics Work

A team of investigators from UC Davis and Peking University have discovered a mechanism that may explain how alpha hydroxyl acids (AHAs) -- the key ingredient in cosmetic chemical peels and wrinkle-reducing creams - work to enhance skin appearance. An understanding of the underlying process may lead to better cosmetic formulations as well as have medical applications. The findings were published in the Journal of Biological Chemistry in an article entitled "Intracellular proton-mediated activation of TRPV3 channels accounts for exfoliation effect of alpha hydroxyl acids on keratinocytes." AHAs are a group of weak acids typically derived...
