New therapy substitutes missing protein in those with muscular dystrophy
Researchers at the University of Minnesota Medical School have discovered a new therapy that shows potential to treat people with Duchenne muscular dystrophy, a fatal disease and the most common form of muscular dystrophy in children.
In the mouse model, researchers were able to substitute for ...
Genetic differences between yeasts greater than those between humans and chimpanzees
The mapping of the entire yeast genome in 1996 marked the beginning of a revolution in biological and medical research. The human genome was mapped in 2001, and by now the number of characterised species is approaching 1000, most of which are bacteria. The next advance is only a few years away ma...

Cigarette smoking may accelerate disability in those with MS
BUFFALO, N.Y. -- Persons with multiple sclerosis who smoke risk increasing the amount of brain tissue shrinkage, a consequence of MS, and the subsequent severity of their disease, new research conducted at the Buffalo Neuroimaging Analysis Center (BNAC) at the University at Buffalo has shown.
Older men treated for early prostate cancer live longer than those who are not
Recent findings from an observational study by researchers at the University of Pennsylvania School of Medicine suggest that men between 65 and 80 years of age who received treatment for early stage, localized prostate cancer lived significantly longer than men who did not receive treatment. The st...
Light-sensitive photoswitches could restore sight to those with macular degeneration

Optical switches like these could trigge...
New discovery blurs distinction between human cells and those of bacteria

New Lab Research May Help Those Deafened By Immune System Attack
Our immune system protects us from disease, destroying invading microbes with a swarm of attacking cells. But it can also go haywire for no apparent reason, ganging up on normal tissues in our body and wreaking havoc.
In thousands of people each year, the immune system attacks the inner ear, home...
One gene links newborn neurons with those that die in diseases such as Alzheimer's
In certain parts of the brain, cells called neurons go through a cycle of death and replenishment. New research from Rockefeller University's Fernando Nottebohm, Ph.D., shows that these replaceable neurons share something in common with the neurons that die in people with diseases such as Alzheimer...
