Researchers discover genetic cause for word-finding disease

...rm of dementia, people lose the ability to express themselves and understand speech. "This discovery, for the first time, provides a molecular approach to understanding the causes and eventually the treatment for this disease, " said Marsel Mesulam, M.D., lead author of the study and the Ruth and Evelyn Dunb...

Rural America more prepared for disaster -- also more vulnerable

Scientists crack the genome of the parasite causing trichomoniasis

...o the scientists were stumped. They first assured themselves their work wasn't in error and that they indeed were sequencing Trichomonas. "That made a kind of Sherlock Holmes approach necessary," she says. After all, there was little information known about the genome of this pathogen. Then bioinformatics expe...

Scientists find potential 'off-switch' for HIV virus

...aps we can get SirT1 and related enzymes to assert themselves immediately, forcing HIV into hibernation with high frequency and reducing the threat to the host." Weinberger said that drugs already exist that target other cellular enzymes, so there is reason to hope the approach will work. "There is preced...

MIT creates 3-D scaffold for growing stem cells

... acids called self-assembling peptides to organize themselves into useful structures. Working with visiting graduate student Fabrizio Gelain from Milan, Zhang created a designer scaffold from a network of protein nanofibers, each 5,000 times thinner than a human hair and containing pores up to 20,000 times smal...

How does a zebrafish grow a new tail?

... of cells to become there, and how many cells like themselves should be reproduced. These streams of signals also tell stem cells in adult organisms what functions to undertake. Once tissue formation starts, something has to tell it to stop before growth gets out of hand. In the Dec. 21, 2006 online edition o...

Longevity gene also protects memory, cognitive function

...lieve that smaller particles can more easily lodge themselves in blood vessel linings, leading to the fatty buildup that can cause heart attacks and strokes. The study examined 158 people of Ashkenazi, or Eastern European, Jewish descent, who were 95 years old or older. Those who had the gene variant were tw...

Gene tied to longevity also preserves ability to think clearly

...ger cholesterol particles are less likely to lodge themselves in blood vessels. So people with the CETP VV gene (and the larger cholesterol particles they produce) run a lower risk of heart attacks and strokes, which may explain their unusual longevity. The findings of this new study suggest that CETP VV als...

Cellular cues identified for stroke recovery

The neurons were found to arrive at the site within the first two to four weeks after the stroke. Further, the researchers found that two p...

Wolves are suffering less from inbreeding than expected

Whether this is because the genetically diverse wolves are more healthy and stronger and thus more likely to become reproductively active, or if they are more preferred as mates by the opposite sex, we do not kn...

The toxins then insinuate an enzyme into the neuron that degrades key proteins required for neurons to communicate with one another.

By studying these individuals, the scientists were able to determine that a mutation in the gene SCN9A causes a loss of function in the voltage-gated sodium channel it encodes (subunit Nav1.7).
