Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

...t these patterns may be set early on, perhaps even before birth, said lead author Thomas OConnor, Ph.D., associate professor of Psychiatry at the University of Rochester Medical Center. This is another piece in the unfolding mystery of just how much the prenatal environment may shape a childs health and dev...

Genomic Analysis Uncovers New Targets for HIV Vaccine

... tests documenting viral loads after infection and before they started receiving antiretroviral treatment. The three polymorphisms were identified after all the blood samples of the selected patients were screened for more than 555,000. Additionally, the researchers discovered many other genetic variants ...

Researchers discover inherited mutation for leukemia

...1, which normally helps trigger the death of cells before they become cancerous. Researchers identified the mutation by testing a family in which the father, four sons, a grandson and a distant female relative developed this form of leukemia. The chemical change is called DNA methylation. Healthy cells ...

Agent slows aging in mice

...e results in animals. Much more research is needed before any possible human anti-aging drug could emerge, Miller says. “Even if this agent turns out to be good for mice, it won’t be possible to tell without careful studies of humans whether NDGA is beneficial, useless, or harmful to people. Occasional...

Blood test may help signal tumor's remission, return in throat cancer patients

...t for advanced throat cancer. Starting immediately before treatment and continuing every three months for 12 months, the researchers tested the patients’ blood for five proteins that, in previous studies, had been found to occur at heightened levels in head and neck cancer patients. These include two cytoki...

Liver cancer patients with high serum levels of hepatitis B virus face poorer outcomes

New bacterium discovered -- related to cause of trench fever

...e was infected with a new bacterium that had never before been isolated from a human. A UCSF infectious disease team, in collaboration with colleagues from other institutions, found that the new microbe is genetically similar to one spread by body lice in the trenches during World War I.
