Blocking CaM kinase may help prevent cardiac rupture

For people who initially survive a heart attack, a significant cause of death in the next few days is cardiac rupture -- literally, bursting of the heart wall. A new study by University of Iowa researchers pinpoints a single protein as the key player in the biochemical cascade that leads to cardiac rupture.

Women much more likely to suffer from “broken heart syndrome”

Researchers have found that a woman’s heart is broken more easily than a man’s. In fact females are seven to nine times more likely to suffer “broken heart syndrome,” when sudden or prolonged stress like an emotional breakup or death causes overwhelming heart failure or heart attack-like symptoms, the first nationwide study of this finds. Usually patients recover with no lasting damage add researchers.

Researchers uncover central component of fat metabolism

Obesity-related diseases are an increasing health problem. Researchers at the University of Oslo have now uncovered a central component of fat metabolism.

Anesthesia and liposuction

Liposuction is a body contouring procedure, not a cure for obesity. The results are judged with a mirror and not a scale. The procedure is ideally suited for men and women with localized fat deposits that are resistant to diet and exercise. Men typically want their "spare tire" and excess fat on their chest removed, while women want their abdomen, hips, and thighs reduced.

Heart specialists reveal how pacemaker works at the biological level

Heart specialists at Johns Hopkins have figured out how a widely used pacemaker for heart failure, which makes both sides of the heart beat together to pump effectively, works at the biological level.

Scientists identify molecular pathway that plays a key role in stress-related DNA damage

Working closely with a team of researchers from Duke University, scientists from the Florida campus of The Scripps Research Institute have helped identify a molecular pathway that plays a key role in stress-related damage to the genome, the entirety of an organism's hereditary information.

Scientists discover mechanism that helps explain why stress causes DNA damage

For years, researchers have published papers that associate chronic stress with chromosomal damage. Now researchers at Duke University Medical Center have discovered a mechanism that helps to explain the stress response in terms of DNA damage.

Scientists reveal complete three-dimensional atomic structure of an activated GPCR

G protein-coupled receptors (GPCRs) are popular drug targets, accounting for about one-third of approved drugs and many hundreds of drugs currently in development. They act as molecular switches that transduce extracellular signals by activating heterotrimeric G proteins located at the inside of the cell.

PACA study: Adrenaline can treat cardiac arrest

Adrenaline has kept its place in cardiac arrest guidelines despite limited evidence for or against its use. The PACA study by Jacobs and colleagues, soon to be published in Resuscitation, the official journal of the European Resuscitation Council, provides the best evidence to date supporting the use of adrenaline to treat cardiac arrest.

Novel neurotransmitter could fight against neurological diseases

A team of scientists has discovered that D-aspartic acid is a novel neurotransmitter that could potentially be used in the fight against neurological diseases such as Parkinson's and schizophrenia.

Cell receptor recycling mechanism discovery opens up new class of therapeutic targets

Prof. Manojkumar Puthenveedu of Carnegie Mellon University studies the mechanisms by which membrane trafficking controls and co-ordinates the complex signalling pathways in the brain. Despite the fact that almost all diseases can be traced to a defect in how cells respond to signals, little is known about how signalling pathways are maintained in normal cells and the changes that occur in abnormal conditions.

Anaphylaxis through the eyes of the food-allergic child

New research shows young people who have experienced life-threatening anaphylactic shock from specific food exposures have significantly different views of the risks associated with their allergies based on their age and can benefit from discussing their perceptions of the safety of their school environment in improving their ability to cope.

Researchers discover recycling mechanism of signaling receptors

An international team of researchers led by Carnegie Mellon University's Manojkumar Puthenveedu has discovered the mechanism by which signaling receptors recycle, a critical piece in understanding signaling receptor function. Writing in the journal Cell, the team for the first time describes how a signaling receptor travels back to the cell membrane after it has been activated and internalized.

FP/TMEM127 gene germline mutations associated with adrenal gland tumors

Analysis has identified variations of a gene that are associated with a type of tumor that forms within the adrenal gland, according a study in the December 15 issue of JAMA. The age group in which these variations were found are frequently excluded from genetic screening models for this type of tumor.
