Transplantation of new neurons into damaged area of the brain could restore brain functions

Without neurons reacting to the blood leptin level, the brain does not control the feeling of hunger and fullness. This type of genetic defects results in severe obesity in humans and animals.

Benefits of vitamin D-fortified yoghurt drink for people with diabetes

People with diabetes are known to have an increased risk of heart disease. New research published in BioMed Central's open access journal BMC Medicine shows that regular consumption of a vitamin D-fortified yoghurt drink improves cholesterol levels and biomarkers of endothelial dysfunction, a precursor of heart disease, in diabetics.

NIH-led study advances HIV vaccine research

HIV is coated in sugars that usually hide the virus from the immune system. Newly published research reveals how one broadly neutralizing HIV antibody actually uses part of the sugary cloak to help bind to the virus. The antibody binding site, called the V1/V2 region, represents a suitable HIV vaccine target, according to the scientists who conducted the study. In addition, their research reveals the detailed structure of the V1/V2 region, the last part of the virus surface to be visualized at the atomic level.

Transplantation of tissue-engineered windpipe can benefit patients with tracheal cancer

Tracheal tumors can be surgically removed, but most are too large for the surgery to be successful by the time they are discovered. Therefore, new therapeutic options are needed. Even in patients with operable tumors, the proportion of complete tumor resection is less than 60%. This outcome would be greatly improved if a trachea substitute with similar anatomical, physiological and biomechanical properties of the patient's original trachea were available.

Study looks at effects of antipsychotic drugs on two brain receptors linked to schizophrenia

Researchers from Mount Sinai School of Medicine, have identified the pattern of cell signaling induced by antipsychotic drugs in a complex composed of two brain receptors linked to schizophrenia.

Combination of radiation treatment and LY2109761 can prevent glioblastoma

Glioblastoma is regarded as the most malignant form of brain tumor. In many cases, neurosurgeons are not able to remove such tumors completely because of the risk of destroying too much brain tissue in the process. Moreover, it is often impossible to identify all the fine extensions by which the tumor spreads into surrounding healthy tissue. To at least slow down the growth of tumor cells that have remained in the head, almost all glioblastoma patients are treated by radiotherapy after surgery.

Takeda submits alogliptin plus metformin NDA to FDA for treatment of type 2 diabetes

Takeda Pharmaceutical Company Limited (Takeda) announced today that its wholly-owned subsidiary Takeda Global Research & Development Center, Inc., U.S., submitted a New Drug Application (NDA) to the United States (U.S.) Food and Drug Administration (FDA) for the fixed-dose combination therapy alogliptin/metformin, which combines alogliptin with metformin in a single tablet.

Knocking out one copy of IGF1 receptor fails to increase life span of male mice

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even if their bodies were less responsive to insulin, the hormone that lowers blood sugar.

Two-drug combination may alleviate radiation sickness in people

A combination of two drugs may alleviate radiation sickness in people who have been exposed to high levels of radiation, even when the therapy is given a day after the exposure occurred, according to a study led by scientists from Dana-Farber Cancer Institute and Children's Hospital Boston.

Stress chemicals shut down and brain processes emotional experiences during REM sleep

They say time heals all wounds, and new research from the University of California, Berkeley, indicates that time spent in dream sleep can help. UC Berkeley researchers have found that during the dream phase of sleep, also known as REM sleep, our stress chemistry shuts down and the brain processes emotional experiences and takes the painful edge off difficult memories.

NIH grant to support Cedars-Sinai's Department of Neurology research

The National Institutes of Health has awarded a four-year, $1.4 million grant to Cedars-Sinai's Department of Neurology to study an unexpected recent discovery: After ischemic stroke - the type caused by a clogged artery but with no bleeding into the brain - a normal protein that plays a positive role in blood clotting escapes intact arteries and damages healthy brain cells.

Asymmetric prototypes for mitral valve replacement

The heart's valves, which guarantee the unidirectional flow of blood from one chamber to another, are asymmetrical. For example, the two flaps of the heart's mitral valve - which regulates blood flow between the left atrium and the left ventricle - vary in size by up to 70 percent.
