PERC-led study recognized as one of Canada's top achievements in health research

You could call it paying it forward. A trip to the Emergency Department (ED) is every parent's worst nightmare. But what if the information documented as a result of your child's visit could help a child with similar symptoms a few provinces away? Terry Klassen and his research team of leading pediatric emergency physicians at Pediatric Emergency Research of Canada (PERC) have done just that and the impact of their research is today recognized as one of the Top Canadian Achievements in Health Research in 2011.

Excess salt stimulates production of adrenalin and causes hypertension

A review article by researchers at Boston University School of Medicine (BUSM) debunks the widely-believed concept that hypertension, or high blood pressure, is the result of excess salt causing an increased blood volume, exerting extra pressure on the arteries. Published online in the Journal of Hypertension, the study demonstrates that excess salt stimulates the sympathetic nervous system to produce adrenalin, causing artery constriction and hypertension.

Cutting cardiac sympathetic nerve may help control heart rhythms

What do sweaty palms and abnormal heart rhythms have in common? Both can be initiated by the nervous system during adrenaline-driven "flight or fight" stress reaction when the body senses danger.

Move Day at U-M hospitals goes smoothly

Sunday's move from the now former U-M C.S. Mott Children's Hospital, the Von Voigtlander Women's Hospital and the Adult Bone Marrow Transplant Unit to the new facility began at 7:02 a.m. Sunday with a tiny patient - a baby moving from the Neonatal Intensive Care Unit.

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.

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.

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.
