Measurement Challenges In Detecting Cancer Biomarkers

Effective control of sexually transmitted diseases (STDs) requires treatment of the sexual partners of infected patients. A new study shows that providing infected men with antibiotics to give their partners is more effective than traditional means of contacting and treating the partners, ac...

New study: Sexually transmitted disease treatment can be effectively administered by sex partners

Active Vaccine Prevents Mice From Developing Prion Disease

... infections occur in animals and are thought to be transmitted orally, explains Dr. Wisniewski. The version of prion disease that affects humans usually occurs spontaneously, and only rarely as a result of eating contaminated meat. "The potential use for a prion vaccine in humans is still theoretical," says Dr....

A probe, not an echo

Natural Killers Could Lead to New Hepatitis Treatments

...und by the receptor, a specific chemical signal is transmitted to the interior of the cell. In the case of NKT cells, the researchers found that the mice genetically rendered deficient in CXCR6 showed reduced survival of their NKT cells, but no change in the speed or pattern of their patrolling. The studies sho...

Where bacteria get their genes

...ferent from each other." Most commonly, genes are transmitted by bacteriophages, viruses that specifically hijack bacteria cells. Like tiny syringes, phages inject their own genetic material into the host cell, forcing it to produce new phages. During such an event, genes from the bacterial genome can be incorp...

Researchers make surprise discovery that some neurons can transmit three signals at once

...tial inhibitory neurotransmitters. Information is transmitted between neurons when one cell releases a neurotransmitter at a synapse, the point of contact between cells. When released from a cell, neurotransmitters are sent on a one-way ride that dead ends at the membrane of the adjacent cell. Like lock and key...

OneWorld Health drug receives 'Orphan' designation from U.S. and European regulatory agencies

An estimated 1.5 million people worldwide are currently infected; the number of new VL cases per year is estimated at 500,000; and as many as 200,000 people die annually. M...

The virus also can be spread through blood transfusions, organ transplants and breastfeeding, as well as from mother to child during pregnanc...

But cell signaling networks are so complex that mapping them has been a slow, arduous process. Now, a research team from Stanford, MIT and Harvard has develo...
