Peramivir protects mice from lethal H5N1 infection

...e. Govorkova is the paper’s senior author. "Our findings support the use of peramivir during a pandemic, and we are currently studying the emergence of H5N1 variants that are resistant to this drug and may occur in the course of treatment," said Natalia A. Ilyushina, Ph.D., a postdoctoral fellow in Webster...

Master regulatory gene of epithelial stem cells identified

...ut of the regenerative epithelial stem cells. The findings also have implications for cancers of the skin, breast and prostate, which are among the most common human malignancies. The role of p63 in epithelial stem cells has been controversial. Some studies found that p63 maintains a steady pool of the rege...

Traumas like Sept. 11 make brains more reactive to fear

...memories -- more sensitive in cases of PTSD. The findings suggest that events that trigger shock, fear and horror that are within a normal range -- may cause similar changes in the brain that traumas do. Victims may experience lingering symptoms (bad dreams, jumpiness, thinking about the incident and avoidi...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

... An important issue in genetics research is that findings correlating specific genes with specific diseases in one population may not apply to other populations. This study addressed that issue by focusing on US participants of European ancestry, then repeating the study in a large group of patients in Ger...

Fat screen delivers plant-derived chemical with antidiabetic effects

... effects attributed to TZDs, Tontonoz said. The findings provide "a second example of a small molecule that both promotes fat cell differentiation in vitro and improves glucose tolerance in vivo," Tontonoz's team concluded. The biological activities of harmine and TZDs underscore the fact that links betwee...
