Scripps research team develops technique to determine ethnic origin of stem cell lines

An international team of scientists led by researchers at The Scripps Research Institute has developed a straightforward technique to determine the ethnic origin of stem cells. more  

Chlorophylls effective against aflatoxin

A new study has found that chlorophyll and its derivative chlorophyllin are effective in limiting the absorption of aflatoxin in humans. Aflatoxin is produced by a fungus that is a contaminant of grains including corn, peanuts and soybeans; it is known to cause liver cancer and can work in concert with other health concerns, such as hepatitis. more

The cancer 'TRAP'

Current research suggests that TNF-receptor associated protein-1 (TRAP-1) may prevent cancer cell death. The related report by Leav et al, "Cytoprotective Mitochondrial Chaperone TRAP-1 as a Novel Molecular Target in Localized and Metastatic Prostate Cancer," appears in the January 2010 issue of the American Journal of Pathology. more  

Rapid flu testing

Researchers from the Medical College of Wisconsin, the Children's Research Institute, and the Children's Hospital of Wisconsin have developed a rapid, automated system to differentiate strains of influenza. The related report by Beck et al, "Development of a rapid automated influenza A, influenza B, and RSV A/B multiplex real-time RT-PCR assay and its use during the 2009 H1N1 swine-origin influenza virus (S-OIV) epidemic in Milwaukee, Wisconsin," appears in the January 2010 issue of the Journal of Molecular Diagnostics. more

Findings suggest cardiovascular devices often approved by FDA without high-quality studies  

Pre-market approval by the FDA of cardiovascular devices is often based on studies that lack adequate strength or may have been prone to bias, according to a study in the December 23/30 issue of JAMA. The researchers found that of nearly 80 high-risk devices, the majority received approval based on data from a single study. more

Older adults who used the herbal supplement Ginkgo biloba for several years did not have a slower rate of cognitive decline compared to adults who received placebo, according to a study in the December 23/30 issue of JAMA. more

Molecular chaperone keeps bacterial proteins from slow-dancing to destruction

Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients. And at the molecular level, just as at the high school gym level, it's a job that usually requires a lot of energy. more
