Discovery highlights potential to combat HIV/AIDS

Researchers at the University of Minnesota have discovered how HIV binds to and destroys a specific human antiviral protein called APOBEC3F. The results suggest that a simple chemical change can convert APOBEC3F to a more effective antiviral agent and that shielding of a common feature shared by related proteins may yield a similar outcome.

BioTime enters MTA with UC to make research-grade hES cell lines

BioTime, Inc. today announced a material transfer agreement (MTA) with the University of California (UC) system to make five research-grade human embryonic stem (hES) cell lines available to UC system researchers. These lines are genetically identical to a bank of GMP-compliant hES cell lines that will be made available to California-based researchers under a recent agreement between BioTime and the California Institute for Regenerative Medicine (CIRM).

Researchers identify new regulator that play a critical role in B cell development

A team at the Institut de recherches cliniques de Montr-al led by Dr. Tarik M-r-y, President and Scientific Director of the institute and Director of the Hematopoiesis and Cancer research unit, will be publishing an important breakthrough in tomorrow's issue of Immunity, a scientific journal from the Cell Press group. The researchers identified a new regulator playing a critical role in the development B cells, which produce antibodies.

Fried fish consumption may increase risk of stroke

People living in the "stroke belt" states eat more fried fish than people living in the rest of the country, which may contribute to the high rate of death from stroke in those states, according to a study published in the December 22, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Research: Arsenic trioxide may benefit individuals with connective brain tumors

Arsenic is usually thought of as a poison. Despite this, it has been used in medicine for over 2000 years, and the arsenic compound arsenic trioxide (ATO) is FDA approved for the treatment of acute promyelocytic leukemia.

New method predicts outcome of bleaching treatment for teeth

Researchers at the University of Granada have developed a new method for predicting the precise shade that a bleaching treatment will bring about for a patient's teeth.

Certain drugs may block tumor host interactions but do not destroy cancer cells

A class of drugs thought to kill cancer cells may in fact block "cross talk" between the cancer cell and normal immune cells, resulting in reduced cancer growth and spread-a discovery that could significantly alter the way cancer drugs are evaluated in the future.

Patients with over expression of P-Rex1 protein are more likely to develop cancer metastasis

Overexpression or hyperactivation of ErbB cell-surface receptors drives the growth of many breast cancers. Drugs, like Herceptin, that block the receptors' signals halt tumor progression in some patients.

New study reveals statin therapy linked to reduced postoperative mortality

Statin drugs were first introduced to lower blood cholesterol concentrations; however, research is now discovering other benefits. A new study from France, published in the January 2011 issue of Anesthesiology, is the first to analyze the impact of preoperative chronic statin therapy on postoperative adverse events in surgical patients. Findings from the study suggest that statin therapy is associated with reduced postoperative mortality.

Photon-based radiation therapy may result in better survival rate in patients with spinal-cord tumor

A study comparing the long-term outcomes of patients with spinal-cord tumors following radiation therapy suggests that certain subsets of patients have better long-term survival.

Genetic variant of brain receptor molecule may contribute to impulsive behavior

A multinational research team led by scientists at the National Institutes of Health has found that a genetic variant of a brain receptor molecule may contribute to violently impulsive behavior when people who carry it are under the influence of alcohol.

Researchers discover protein that suppresses melanoma progression

In a breakthrough that could lead to new treatments for patients with malignant melanoma, researchers from Mount Sinai School of Medicine have discovered that a particular protein suppresses the progression of melanoma through regulation of an oncogene, or gene responsible for cancer growth. The study is published in the December 23 issue of Nature.

Minorities with MS may face risk of developing depressive symptoms

Multiple sclerosis can cause significant physical impairment, including fatigue, pain, muscle spasms, tremors and dizziness. For many with MS, the disease wreaks havoc with emotional well-being, too, and according to a new study, minorities might especially be at risk for developing depressive symptoms.

Novel method to analyze fatigue through speech

What can scientists learn from watching a group of people sitting around, chatting, playing movies, reading, and happily making new friends? Quite a lot, says University of Melbourne, Australia acoustician Adam Vogel, who carefully observed this sort of group in a fatigue management study he and his colleagues describe this month in The Journal of the Acoustical Society of America.

People with high RBC folate levels more likely to have two tumor-suppressing genes

People with higher levels of folate in their red blood cells were more likely to have two tumor-suppressing genes shut down by methylation, a chemical off switch for genes, researchers report in the December issue of Cancer Prevention Research.

Researchers identify class of drugs that can promote RBC formation in anemic patients

By determining how corticosteroids act to promote red blood cell progenitor formation, Whitehead Institute researchers have identified a class of drugs that may be beneficial in anemias, including those resulting from trauma, sepsis, malaria, kidney dialysis, and chemotherapy.
