Researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) have developed a novel technique to promote tissue repair in damaged muscles. Continue reading

Disease in a dish approach could aid Huntington’s disease discovery

Disease in a dish approach could aid Huntington’s disease discovery

Creating induced pluripotent stem cells or iPS cells allows researchers to establish “disease in a dish” models of conditions ranging from Alzheimer’s disease to diabetes. Scientists at Yerkes National Primate Research Center, Emory University have now applied the technology to a model of Huntington’s disease (HD) in transgenic nonhuman primates, allowing them to conveniently assess the efficacy of potential therapies on neuronal cells in the laboratory.

Important regulators of immune cell response identified

Important regulators of immune cell response identified

In a collaborative study, scientists from the Florida campus of The Scripps Research Institute (TSRI) and the La Jolla Institute for Allergy and Immunology have developed a more effective method to determine how immune cells called T cells differentiate into specialized types of cells that help eradicate infected cells and assist other immune cells during infection. The new approach, published recently by the journal Immunity , could help accelerate laboratory research and the development of potential therapeutics, including vaccines. The method may also be used to identify the genes that underlie tumor cell development. Continue reading

Training your brain to prefer healthy foods

Training your brain to prefer healthy foods

It may be possible to train the brain to prefer healthy low-calorie foods over unhealthy higher-calorie foods, according to new research by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University and at Massachusetts General Hospital. Published online today in the journal Nutrition & Diabetes , a brain scan study in adult men and women suggests that it is possible to reverse the addictive power of unhealthy food while also increasing preference for healthy foods. “We don’t start out in life loving French fries and hating, for example, whole wheat pasta,” said senior and co-corresponding author Susan B Continue reading

Leading Ebola researcher says there’s an effective treatment for Ebola

Leading Ebola researcher says there’s an effective treatment for Ebola

A leading U.S. Ebola researcher from the University of Texas Medical Branch at Galveston has gone on record stating that a blend of three monoclonal antibodies can completely protect monkeys against a lethal dose of Ebola virus up to 5 days after infection, at a time when the disease is severe. Thomas Geisbert, professor of microbiology and immunology, has written an editorial for Nature discussing advances in Ebola treatment research. Continue reading

Home is where the microbes are

Home is where the microbes are

A person’s home is their castle, and they populate it with their own subjects: millions and millions of bacteria. A study published tomorrow in Science provides a detailed analysis of the microbes that live in houses and apartments. Continue reading

Encyclopedia of how genomes function gets much bigger

Encyclopedia of how genomes function gets much bigger

A big step in understanding the mysteries of the human genome was unveiled today in the form of three analyses that provide the most detailed comparison yet of how the genomes of the fruit fly, roundworm, and human function. The research, appearing August 28 in in the journal Nature, compares how the information encoded in the three species’ genomes is “read out,” and how their DNA and proteins are organized into chromosomes. The results add billions of entries to a publicly available archive of functional genomic data Continue reading

Xenon exposure shown to erase traumatic memories

Xenon exposure shown to erase traumatic memories

McLean Hospital researchers are reporting that xenon gas, used in humans for anesthesia and diagnostic imaging, has the potential to be a treatment for post-traumatic stress disorder (PTSD) and other memory-related disorders. “In our study, we found that xenon gas has the capability of reducing memories of traumatic events,” said Edward G. Meloni, PhD, assistant psychologist at McLean Hospital and an assistant professor of Psychiatry at Harvard Medical School. Continue reading

Aspirin may reduce the risks of reoccurring blood clots

Aspirin may reduce the risks of reoccurring blood clots

Aspirin may be a promising alternative for those who can’t take long-term anticoagulant drugs that prevent clots from reoccurring in the veins, according to new research in the American Heart Association journal Circulation. In a combined analysis of two similar independent studies, 1,224 patients who received 100 mg of aspirin a day to treat blood clots were monitored for at least two years. Continue reading
