1/23/14 Health News: Salmonella Biofilms Resists Disinfectants - Concussions Diagnosed on Sports Field - Toxin Kills of HIV- Mediterranean Diet Cuts Type 2 Diabetes

Researchers have discovered that common disinfectants face an uphill battle killing Salmonella once it has had the time to form a biofilm – a community of cells that attach to each other and a surface, increasing the density of bacterial growth and providing support from harsh environments. Researchers at the National University of Ireland, Galway,... Continue Reading

A New Blood Test to Diagnose Concussions on the Sports Field
A protein could signal the first signs of brain changes due to a concussion.
With a finger-stick and a drop of blood, researchers from the University of Rochester say it may be possible to tell whether a player experienced a concussion. Levels of the brain protein S100B start to rise with intense exertion, but also after a major impact such as a blow to the head. So the scientists investigated whether it would be possible to distinguish the two circumstances in hopes of finding a way to detect the first signs of traumatic brain injury. Based on their findings, the researchers concluded that a rise in S100B of more than 45% is nearly equivalent to a concussion diagnosis, and easily distinguishable from physical exertion..continue reading

Toxin Shows Promise in Killing Off Lurking HIV
An antibody and toxin mix has successfully detected and killed HIV-infected cells lurking in the organs and bone marrow of mice that were altered to have a human immune system. The results, reported offer conceptual proof that a reservoir of HIV-infected cells in organs can sought out and destroyed, a scenario that would potentially end the stalemate between the virus and antiretroviral drug therapies. The altered mice, developed about eight years ago, can be infected by the human immunodeficiency virus in an identical manner to humans; they exhibit the same viremia and respond the same way to current antiretroviral drug therapy, but do not come down with AIDS, according to the study.Continue Reading

Mediterranean Diet Cuts Type 2 Diabetes Risk by a Third

A Mediterranean diet supplemented with extra-virgin olive oil cut the risk for developing type 2 diabetes by about a third among adults at high risk for cardiovascular disease (CVD) compared with a low-fat diet, a new analysis finds. The results, from the subgroup of subjects in the Spanish cardiovascular prevention study Prevencion con Dieta Mediterránea who did not have diabetes at baseline Source:.continue reading
