Researchers develop new approach for HIV vaccine development

Decades of research and three large-scale clinical trials have so far failed to yield an effective HIV vaccine, in large part because the virus evolves so rapidly that it can evade any vaccine-induced immune response.

Soybeans can prevent cancer

Soybean meal is a bi-product following oil extraction from soybean seeds. It is rich in protein, which usually makes up around 40% of the nutritional components of the seeds and dependent on the line, and can also contain high oleic acid (a monounsaturated omega-9 fatty acid).

Researchers: Acupuncture can reduce stress hormone response in animal model of chronic stress

While acupuncture is used widely to treat chronic stress, the mechanism of action leading to reported health benefits are not understood. In a series of studies at Georgetown University Medical Center, researchers are demonstrating how acupuncture can significantly reduce the stress hormone response in an animal model of chronic stress.

Scientists to create new human monoclonal antibody targeting protein associated with cancer

Researchers have discovered a unique monoclonal antibody that can effectively reach inside a cancer cell, a key goal for these important anticancer agents, since most proteins that cause cancer or are associated with cancer are buried inside cancer cells.

Genetic mutation that alters PIEZO1 ion channel in RBCs contributes to familial xerocytosis

A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a paper published this month in the Proceedings of the National Academy of Sciences by University at Buffalo scientists and colleagues.

Boosting hypocretin could elevate both mood and alertness in humans

What makes us happy? Family? Money? Love? How about a peptide? The neurochemical changes underlying human emotions and social behavior are largely unknown. Now though, for the first time in humans, scientists at UCLA have measured the release of a specific peptide, a neurotransmitter called hypocretin, that greatly increased when subjects were happy but decreased when they were sad.

Study finds how to shut down Bcl6 in diffuse large B-cell lymphoma

The powerful master regulatory transcription factor called Bcl6 is key to the survival of a majority of aggressive lymphomas, which arise from the B-cells of the immune system. The protein has long been considered too complex to target with a drug since it is also crucial to the healthy functioning of many immune cells in the body, not just B cells gone bad.
