Genomic Analysis Uncovers New Targets for HIV Vaccine

...to discover the three genes, that together greatly increase our knowledge of why patients differ in how well they can control the virus that causes AIDS. These findings represent only the first of what investigators said will be a series of future genome-wide studies to pinpoint additional targets for HIV va...

Cells re-energize to come back from the brink of death

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

...gy ). HBV is associated with a more than 200-fold increase in risk of liver cancer. In areas where HBV is endemic, like China and the Far East, the great majority of cases of hepatocellular carcinoma (HCC) occur in individuals with the virus. For most patients whose cancer is inoperable, chemotherapy is one ...

Research team identifies new Alzheimer's gene

...earchers to identify a common gene that appears to increase a person’s risk for developing Alzheimer’s disease. The finding, announced today by researchers at the Translational Genomics Research Institute (TGen), Banner Alzheimer’s Institute, Kronos Science Laboratory and their collaborative partners, suggest...

Dirty snow may warm Arctic as much as greenhouse gases

...rimarily responsible for the remaining temperature increase and are considered the Earth’s most important overall climate changing mechanism. Other human influences on Arctic climate change are particles in the atmosphere, including soot; clouds; and land use. Humans create the majority of airborne soot th...

Research shows cord blood comparable to matched bone marrow

... Wagner added that increasing the inventory will increase the chance of finding donors for ethnic and racial minorities currently underrepresented in volunteer marrow registries worldwide. While the study showed that umbilical cord blood took longer to rebuild the blood-making cells in the body, it was ...

Sun exposure early in life linked to specific skin cancer gene mutation

...sure, from birth to 20 years old, may specifically increase the risk of melanomas with BRAF gene mutations. A different mutation, on the NRAS gene, was found in patients who had sun exposure later in life (between ages 50 to 60 years old). The results indicate that different subtypes of melanoma are associate...

Alzheimer's disease to quadruple worldwide by 2050

Because differences between groups of strangers and groups of siblings only occurred when they shared a pot, the root interactions may provide a cue for kin recognition.” Though they lack cognition and memory, the study shows pl...
