Obama declares swine flu a national emergency
Reuters    Share   Share on FacebookTwitterShare on LinkedinE-mail article
U.S. President Barack Obama has declared 2009 H1N1 swine flu a national emergency, the White House said. The declaration will make it easier for U.S. medical facilities to handle a surge in flu patients by allowing the waiver of some requirements of Medicare, Medicaid and other federal health insurance programs as needed. The U.S. Centers for Disease Control and Prevention said that swine flu has become widespread in 46 of the 50 U.S. states, a level comparable to the peak of ordinary flu seasons but far earlier and with more waves of infection expected.

The first successful human womb transplant could take place within two years, British scientists have said. London-based experts say they have worked out how to transplant a womb with a regular blood supply so it will last long enough to carry a pregnancy. Research involving donor rabbits was presented at a U.S. fertility conference. More
Tacrolimus ameliorates metabolic disturbance and oxidative stress caused by Hepatitis C virus core protein
American Journal of Pathology    Share   Share on FacebookTwitterShare on LinkedinE-mail article
Hepatic steatosis and insulin resistance are factors that aggravate the progression of liver disease caused by hepatitis C virus infection. In the pathogenesis of liver disease and metabolic disorders in HCV infection, oxidative stress due to mitochondrial respiratory chain dysfunction plays a pivotal role. Tacrolimus (FK506) is supposed to protect mitochondrial respiratory function. More

AIDS vaccine seen as modest help
The Associated Press via The New York Times    Share   Share on FacebookTwitterShare on LinkedinE-mail article
Fresh results from the world's first successful test of an experimental AIDS vaccine confirm that it is only marginally effective. Yet, the findings are exciting to scientists, who think they may show how to make a better vaccine. The results also hint that the vaccine may work better in the general population than in those at higher risk of infection, such as gay men and intravenous drug users. It was the first time an AIDS vaccine was tested mostly in heterosexuals at average risk, and doctors have long known that how a person is exposed to HIV affects the odds of becoming infected. More
