Calcium flow disruptions linked to heart failure

UCSF researchers have discovered that a protein called B1N1 is necessary for the heart to contract. The findings, published in the Feb. 16 issue of the open access journal PLoS Biology, shed light not only on what makes ...

Abnormal heart rhythms - arrhythmias - are killers. They strike without warning, causing sudden cardiac death, which accounts for about 10 percent of all deaths in the United States.

A calcium-sensing protein, STIM1, known to activate store-operated calcium channels has been found to also inhibit voltage-operated calcium channels, according to researchers at Temple University.

Scientists in the Hotchkiss Brain Institute at the Faculty of Medicine, University of Calgary, have discovered a new mechanism that nerve cells (neurons) use to fine-tune their electrical output. The exciting discovery, published ...

Congenital stationary night blindness, an inherited condition that affects one's ability to see in the dark, is caused by a mutation in a calcium channel protein that shuttles calcium into and out of cells. Now, researchers ...

(June 17, 2009) - An overactive enzyme is behind a leaky calcium channel that plays a role in the development of atrial fibrillation, which is the most common cardiac arrhythmia that is responsible for a third of all strokes. ...

In 2008 researchers from the University of Southern Denmark showed that the drug thioridazine, which has previously been used to treat schizophrenia, is also a powerful weapon against antibiotic-resistant bacteria such as ...

Scientists investigating the interaction of a group of proteins in the brain responsible for protecting nerve cells from damage have identified a new target that could increase cell survival.

New findings by researchers carrying out experiments at the U.S. Department of Energy Office of Science's Advanced Photon Source (APS) help explain why some drugs that interact with two kinds of human serotonin ...

Peptide molecules derived from the body's natural immune system can help boost the body's defence against life-threatening blood poisoning, joint University research has uncovered.

A new Montréal study conducted by Dr. May Faraj, associate research professor at the Université de Montréal and invited scientist at the IRCM, along with her research team and medical collaborators, shows ...

Scientists at Montana State University have developed a therapeutic that has potential as a biological drug or probiotic food product to combat many of the more than 80 autoimmune disorders that affect some 23.5 million people ...
