Stem Cells to Solve the Blood Shortage Problem?

...igate how the number of casualties could have been reduced and, more important, how such severe damage can be avoided if a tsunami ever strikes again. In an essay published this week in the June 21 issue of Current Biology, a group of researchers recount the first findings arising from their recent assessmen...

Scientists find that protein controls aging by controlling insulin

...lotho. They were more sensitive to insulin and had reduced levels of it. The influence on insulin creates a problem for Klotho should it be used as a therapy against aging: It may extend life, but it could also make an animal diabetic. Mice with the excessive Klotho also had fewer offspring than normal m...

Pinpointing the cause of a neurodegenerative disorder

...d her colleagues showed that increases in Ataxin-1 reduced levels of Senseless during peripheral nervous system development, causing developmental abnormalities. Additional experiments demonstrated that enhanced levels of normal and abnormal human Ataxin-1 produced even more serious pathology in the flies. ...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

Divergent life history shapes gene expression in brains of salmon

...ame age known as "sneakers" that mature at greatly reduced size without leaving freshwater. "The finding that hundreds of the nearly 3,000 genes we studied were expressed differently in the brains of sneakers and other male salmon came as a surprise," says Nadia Aubin-Horth, a postdoctoral researcher in the...

Hepatitis C responds best to combo of ribavirin and interferon, study concludes

Investigating 'brain shrinkage' in alcoholics

...nufacture of structural proteins of the myelin was reduced in the alcoholic cases. In addition, the content of these proteins in the white matter was reduced. These changes likely alter the structure and function of the myelin sheath and ultimately the conduction of nerve impulses." - It is important for pe...

Logging changed ecological balance for monkeys, damaged health

Gene therapy to lower blood pressure just enough

...P. In previous studies, however, this kind of gene reduced blood pressure to dangerously low levels, said O'Malley. Obviously, a method of controlling the gene and the amount of ANP a cell makes was needed. The special viral vector developed by O'Malley and his colleagues combines a special kind of adenovir...
