Uric acid may help reduce effects of spinal cord injury, Jefferson researchers find
..."We want to establish the precise timing where the inactivation
of peroxynitrite will have therapeutic benefit," he says. "In the spinal cord, we know many of the changes occur within 24 hours. It's certainly feasible to give someone uric acid immediately and raise levels in 50 minutes. Whether or not this should...

of the lower heart chambers. In this study, researchers performed an ECG on newborns between the 15th and 25th day of life at 16 centers. By April 2004, ECGs were obtained on 21,397 infants. Among those, 173 (0.8 percent) had Q-T interval greater th...

Inactivation of Alzheimer's disease genes in mice causes dementia and brain degeneration
...rs identified the molecular pathways through which inactivation
of these genes in mice produces abnormalities strikingly reminiscent of Alzheimer's disease. The study, reported online in Neuron, may provide a new way to look at the cause of Alzheimer's disease, as it shows that the protein products of these Alzhe...

of SFRP genes occurs in the earliest form of lesion, called an atypical crypt foci (earlier than polyps or cancer). Approximately 5 percent of these lesions become colon cancers. "The colon cancer process may start by shutting off SFRP genes, which...

of BRCA2 in these tumors and that a majority of the tumors with BRCA2 dysfunciton also had BRCA1 dysfunction. The authors conclude that "some degree of BRCA1 and/or BRCA2 dysfunction may be of nearly universal importance for the process of ovarian ca...
Mice lacking fat-making enzyme are leaner, more sensitive to leptin and insulin

of DGAT1 significantly reduced their obesity and insulin resistance. Obesity is a huge public health problem, so people are looking for drugs to cure it, said Robert V. Farese, Jr., MD, senior author, Gladstone investigator, and UCSF professor of med...
