New Drug Has Potential to Treat Hypertension and Heart Disease (12/5/2007)

Investigators at the University of California, San Diego (UCSD) School of Medicine have developed a new drug called nitrosyl-cobinamide, which they have shown in animal models to be potentially more effective than nitroglycerin in increasing coronary blood flow and lowering blood pressure. The report on this study, led by Gerry R. Boss, M.D., UCSD professor of medicine, is currently on line and will be published in the December 7 issue of Experimental Biology and Medicine. ...> Full Article

'Superbug' infections more than doubled in hospitals, study finds (12/3/2007)

Hospitalizations related to a potentially deadly, antibiotic-resistant "superbug" more than doubled between 1999 and 2005, soaring from 127,000 to nearly 280,000, according to a new study co-authored by a University of Florida researcher. ...> Full Article

Exposure to PCBs and Chlorinated Pesticides Linked to Diabetes Among Mohawk Population (12/3/2007)

Exposure to polychlorinated biphenyls (PCBs) and chlorinated pesticides may cause diabetes, according to a study by researchers at the University at Albany's School of Public Health. The study, published in Environmental Health Perspectives (Vol. 115, Issue 10, October 2007), found that there was a nearly four times greater risk of diabetes in Mohawks who had PCB levels in the top one-third of the study population. ...> Full Article

New study finds that sleep duration raises the risk for diabetes (12/2/2007)

The most common factors believed to contribute to diabetes are a decreased amount of physical activity and access to highly palatable processed foods. However, there is growing evidence that another aspect of our modern lifestyle, short sleep duration, is also contributing toward the "diabetes epidemic", according to a study published in the December 1 issue of the journal Sleep. ...> Full Article

DNA Methylation Shown To Promote Development Of Colon Tumors (12/2/2007)

Damaged or defective genes have long been known to be the cause of some cancers. Over the past decade, however, scientists have discovered that even healthy genes can be switched on or off and can cause cancer without any changes in the underlying DNA sequence--although how this happens has remained poorly understood. ...> Full Article

Genomic study of malaria parasite unearths surprising behaviors (12/1/2007)

The malaria parasite has been studied for decades, but surprisingly little is known about how it behaves in humans to cause disease. Now an international team including scientists at the Broad Institute of MIT and Harvard has for the first time measured which of the parasite's genes are turned on or off during actual infection in humans, unearthing surprising behaviors and opening a window on the most critical aspects of parasite biology. ...> Full Article

UCSD Offers Free Test That Can Detect HIV as Early as One Week after Exposure (12/1/2007)

UC-San Diego's Antiviral Research Center (AVRC) is offering free and confidential HIV testing to people who may have a very recent infection with HIV, the retrovirus that can lead to AIDS. The Early Test Program - offered in collaboration with the San Diego County Health and Human Services Agency - offers a new test method that checks for the presence of the HIV virus, which can be detected within a week of infection. In contrast, a regular HIV test looks for antibodies in the blood, which can take three months or more to detect. ...> Full Article
