Vaginal gel shown to protect female monkeys against an HIV-like virus

Research with female monkeys at the Tulane National Primate Research Center has for the first time shown that three different anti-viral agents in a vaginal gel protect the animals against an HIV-like virus.

Researchers determine how Tsg101 gene controls cellular growth

Researchers at Emory University School of Medicine and their colleagues have discovered a genetic mechanism that controls cellular growth in the fruit fly Drosophila melanogaster, and believe it likely that a similar system may be at work in normal and cancerous human cells.

Role of alpha tocopherol associated protein in prostate cancer

Researchers have identified a protein that disrupts an important signaling pathway in prostate cancer cells and suppresses growth of the cancer.

EphA2 represents a promising treatment target for glioblastoma multiforme

Researchers at Wake Forest University Baptist Medical Center have identified a second promising treatment target for glioblastoma multiforme, one of the most deadly types of brain tumors. The research results are reported in the October issue of Molecular Cancer Research.

Discovery of signaling mechanism may help prevent metastatic melanoma

Researchers at Northwestern University have discovered a key signaling mechanism that may promote the ability of highly aggressive malignant melanoma cells to metastasize, or spread from a primary tumor to distant sites within the body.

INTERACT trial to look at effects of early intensive blood pressure lowering on death and disability in stroke patients

A large clinical trial called INTERACT, launched in China this month, will determine the effects of early intensive blood pressure lowering on death and disability in stroke patients.

Unique approach to enhance the immune system in patients with breast or colorectal cancer

The study uses a potent immune-enhancing gene delivered directly into the cancer cells to make them look foreign to the body's immune system, which will then attack and destroy the cancer.

Gene fusion appears to cause prostate cancer

Scientists at the University of Michigan Medical School, in collaboration with researchers at Harvard's Brigham and Women's Hospital, have discovered a recurring pattern of scrambled chromosomes and abnormal gene activity that occurs only in prostate cancer.

HDLs provide human immunity to certain parasites

For years biomedical researchers have known that high density lipoproteins, commonly called HDLs or "good cholesterol," are responsible for protecting humans from certain parasites, but couldn't explain how.

Morphine withdrawal enhances hepatitis C virus (HCV) replicon expression

Researchers at the University of Pennsylvania have demonstrated that morphine withdrawal complicates hepatitis C by suppressing IFN-alpha-mediated immunity and enhancing virus replication.

Cichlid fish provide better understanding of the genetic factors that regulate bone shape

Researchers at the Forsyth Institute have discovered that the genes that influence the jaws of cichlid fish, tropical freshwater fish renowned for head shape diversity, offer insight into overall vertebrate diversity.

Search for genes responsible for anxiety disorders

Increasing the activity of two enzymes better known for their role in oxidative stress metabolism turns normally relaxed mice into "Nervous Nellies," according to research conducted at the Salk Institute for Biological Studies and reported in the early online edition of Nature.

Scientists unravel complex mechanisms in the brain that regulate body weight

Scientists are one step closer to unraveling the complex mechanisms in the brain that regulate body weight. Working with mice -- whose appetites are controlled by systems very similar to those in humans – they have identified a specific type of neuron that is essential for feeding behavior.

Trigger discovered that causes stem cells embryos to start developing into organs

They have apparently discovered the chemical trigger that causes stem cells from embryos to start developing into organs, raising the possibility of parts of the body being able to repair their own damage.

Type 2 diabetes and depression can be a fatal mix

Patients whose type 2 diabetes was accompanied by minor or major depression had higher mortality rates, compared to patients with type 2 diabetes alone, over the three-year period of a recent study in Washington state.

New insights into how genetic mutations arise

Researchers at Stanford University have created a larger-than-normal DNA molecule that is copied almost as efficiently as natural DNA.

New understanding of how neurogenesis occurs

Scientists at the Salk Institute for Biological Studies have identified a crucial cellular signal that controls the fate of stem cells in the brains of adult mice.

Bird flu in Germany - Britain and Europe ban all bird imports

Following the discovery of signs of the bird flu virus in two dead migratory birds at a lake in Neuwied, Germany, a ban is shortly to be imposed on the import of all captive birds from around the world plus a ban on all bird fairs, exhibitions and shows, to protect Britain and Europe from the deadly avian flu virus.
