Researchers describe new function of HCN channels in the heart

The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials. Action potentials result from the controlled flow of ions into heart muscle cells (depolarization) through channels in their membranes, and are followed by a compensating reverse ion current (repolarization), which restores the original state. If the duration of the repolarization phase is not just right, the risk of ventricular arrhythmia and sudden cardiac death increases significantly.

Researchers identify bouncer protein that plays a vital role in RA prevention

Researchers at Northwestern University Feinberg School of Medicine have discovered why the immune cells of people with rheumatoid arthritis become hyperactive and attack the joints and bones. The immune cells have lost their bouncer, the burly protein that keeps them in line the same way a bouncer in a nightclub controls rowdy patrons.

International researchers to assess role of pre-clinical animal models in drug discovery

The New York Academy of Sciences and the Global Medical Excellence Cluster (GMEC), in collaboration with Imperial College London and King's College London, will host a two-day scientific conference, "Animal Models and Their Value in Predicting Drug Efficacy and Toxicity," that will provide a forum to critically examine the role of pre-clinical animal models in drug discovery.

New insights into Lafora disease

Short-term energy storage in animal cells is usually achieved through the accumulation of glucose, in the form of long and branched chains, known as glycogen. But when this accumulation happens in neurons it is fatal, causing them to degenerate. This neuronal deterioration and death associated with glycogen accumulation is the hallmark of an extremely rare and progressive type of epilepsy known as Lafora disease (LD).

Specific inhibitor of microRNA-100 can stimulate development of new blood vessels

A specific inhibitor of the small regulatory RNA-molecule "microRNA-100" can be used to stimulate the growth of new blood vessels, if a major artery is chronically occluded.

RE Children's Project donates $111,000 to UCLA researchers for Rasmussen Encephalitis study

The Rasmussen Encephalitis (RE) Children's Project, a foundation that supports scientific research to find a cure for this devastating neurological disease, has donated $111,000 to researchers in the departments of neurosurgery and pathology/lab medicine (neuropathology) at Ronald Reagan UCLA Medical Center.

Researchers discover how antipsychotic drugs manage symptoms of schizophrenia

The classic symptoms of schizophrenia - paranoia, hallucinations, the inability to function socially-can be managed with antipsychotic drugs. But exactly how these drugs work has long been a mystery.

Scientists discover key defense mechanism against C. difficile infection

Researchers have discovered a key mechanism used by intestinal cells to defend themselves against one of the world's most common hospital-acquired bacterial infections - a mechanism they think they can exploit to produce a therapy to protect against the effects of the antibiotic-resistant bacteria.

Scientists identify common cause of all forms of amyotrophic lateral sclerosis

The underlying disease process of amyotrophic lateral sclerosis (ALS and Lou Gehrig's disease), a fatal neurodegenerative disease that paralyzes its victims, has long eluded scientists and prevented development of effective therapies. Scientists weren't even sure all its forms actually converged into a common disease process.

Researchers document how immune system can counteract advancement of Alzheimer's

For the first time a research team at Charité - Universitätsmedizin Berlin and Universitätsklinik Freiburg succeeded in documenting how the immune system can counteract the advancement of Alzheimer's disease.

New treatment uses lasers to stimulate stem cells and reduce heart scarring

After a heart attack or stroke, heart scarring can lead to dangerously paper-thin heart walls and a decreased ability to pump blood through the body. Although the heart is unable to completely heal itself, a new treatment developed at Tel Aviv University uses laser-treated bone marrow stem cells to help restore heart function and health.

Stem cells could provide sperm for infertile males

Researchers have been successful in creating sperm-producing germ cells from stem cells in a lab and transferred them into infertile mice, which after the treatment were able to produce healthy offspring. This new development could help thousands of infertile men become fathers if the method proves similarly effective in humans.
