Reduction in myelin production may also play a role in development of mental illness

Reduced production of myelin, a type of protective nerve fiber that is lost in diseases like multiple sclerosis, may also play a role in the development of mental illness, according to researchers at the Graduate School of Biomedical Sciences at Mount Sinai School of Medicine. The study is published in the journal Nature Neuroscience.

microRNA-223 molecule plays a surprising role in protecting brain cells from stroke effects

A small molecule known to regulate white blood cells has a surprising second role in protecting brain cells from the deleterious effects of stroke, Johns Hopkins researchers report. The molecule, microRNA-223, affects how cells respond to the temporary loss of blood supply brought on by stroke - and thus the cells' likelihood of suffering permanent damage.

Disabling ItpkB enzyme improves function of Natural Killer cells

Researchers at The Scripps Research Institute (TRSI) are fueling the future of cancer treatment by improving a powerful tool in disease defense: the body's immune system. By revealing a novel but widespread cell signaling process, the scientists may have found a way to manipulate an important component of the immune system into more effectively fighting disease.

Scientists discover synchronous brain activity between two guitarists

Researchers from the Max Planck Institute for Human Development in Berlin have shown that synchronization emerges between brains when making music together, and even when musicians play different voices. In a study published November 29th in Frontiers in Neuroscience, Johanna S-nger and her team used electrodes to record the brain waves of guitarists while they played different voices of the same duet.

Intramyocardial injection of organ-derived stem cells after AMI improves left ventricle function

A study published in the current issue of Cell Transplantation, now freely available on-line, has found that when mesenchymal cells derived from skeletal muscle (SM-MSCs) or adipose tissue (ADSCs) were injected into the heart muscle (myocardium) of separate groups of laboratory rats that had suffered a myocardial infarction, rats in both groups experienced significantly improved left ventricle function and smaller infarct size after cell therapy.

Gadd45g protein essential in initiating development of male sex organs

Scientists at the Institute of Molecular Biology (IMB) in Mainz have identified a protein essential for initiating the development of male sex organs. Loss of the gene Gadd45g results in complete sex reversal of male mice, making them appear female.

Carnosic acid promotes eye health

Herbs widely used throughout history in Asian and early European cultures have received renewed attention by Western medicine in recent years. Scientists are now isolating the active compounds in many medicinal herbs and documenting their antioxidant and anti-inflammatory activities. In a study published in the journal Investigative Ophthalmology & Visual Science, Stuart A. Lipton, M.D., Ph.D. and colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) report that carnosic acid, a component of the herb rosemary, promotes eye health.

High-resolution real-time images show how nerves may be damaged during earliest stages of MS

High-resolution real-time images show in mice how nerves may be damaged during the earliest stages of multiple sclerosis. The results suggest that the critical step happens when fibrinogen, a blood-clotting protein, leaks into the central nervous system and activates immune cells called microglia.
