A simple blood test for the protein NT-proBNP accurately predicts the risk of heart attack, heart failure, stroke and death in patients with known cardiovascular disease, according to a study led by a researcher at the San Francisco VA Medical Center.
Researchers at the University of Southern California (USC) recently made significant strides toward settling a decades-old debate centering on the role played by stem cells in cancer development. According to the study’s findings, which appear in an upcoming issue of Nature Genetics and now available online, genes that are reversibly repressed in embryonic stem cells are over-represented among genes that are permanently silenced in cancers; this link lends support to the increasingly discussed theory that cancer is rooted in small populations of stem cells.
Mark Ward, Senior Deputy Assistant Administrator for the U.S. Agency for International Development (USAID), spoke at a ‘tsunami relief and recovery’ update briefing at the National Press Club. The purpose of the event was to provide an update on reconstruction activities in the region in recognition of the second anniversary of the Indian Ocean tsunami. Also speaking was Eric Schwartz, the UN Secretary General’s Special Envoy for Tsunami Recovery.
Scientists have discovered a new source of stems cells and have used them to create muscle, bone, fat, blood vessel, nerve and liver cells in the laboratory. The first report showing the isolation of broad potential stem cells from the amniotic fluid that surrounds developing embryos was published today in Nature Biotechnology.
Combining synthetic chemistry techniques with a knowledge of the properties and actions of enzymes, scientists have been able to produce an exciting class of anti-cancer drugs originally isolated from blue-green algae.
A preliminary study suggests there may be hope in the offing for some sufferers of chronic fatigue syndrome with a new therapy being tested by researchers at the Stanford University School of Medicine.
Scientists at the University of Liverpool have found how two molecules fight in the blood to control the spread of cancer cells.
Unexplained chest pain after a heart attack might be more dangerous than many physicians originally think. In a case study to be published in the January issue of the international journal Clinical Cardiology, physicians at Thomas Jefferson University Hospital in Philadelphia report on a seemingly healthy 55-year-old man who had a silent heart attack and subsequent unexplained chest pain.
University of Pittsburgh investigators have successfully prevented the onset of type 1 diabetes in mice prone to developing the disease using an antibody against a receptor on the surface of immune T-cells. According to the investigators, these findings, which are being published in the January issue of the journal Diabetes, have significant implications for the prevention of type 1 diabetes.
A UCL (University College London) study has found that you are more likely to perform well if you do not think too hard and instead trust your instincts. The research, published online today in the journal Current Biology, shows that, in some cases, instinctive snap decisions are more reliable than decisions taken using higher-level cognitive processes.
