Key gene for regenerating cells after heart attack

Key gene for regenerating cells after heart attack

Dec. 20, 2012 — UT Southwestern Medical Center researchers have pinpointed a molecular mechanism needed to unleash the heart’s ability to regenerate, a critical step toward developing eventual therapies for damage suffered following a heart attack Continue reading

Virus rebuilds heart’s own pacemaker

Virus rebuilds heart’s own pacemaker

16 December 2012 Last updated at 13:05 ET By James Gallagher Health and science reporter, BBC News A new pacemaker has been built inside a heart by converting beating muscle into cells which can organise the organ’s rhythm, US researchers report. The heartbeat is controlled by electrical signals and if these go awry the consequences can be fatal. Scientists injected a genetically-modified virus into guinea pigs to turn part of their heart into a new, working pacemaker. Continue reading

Biocompatible patch developed to heal infants with birth defects

Biocompatible patch developed to heal infants with birth defects

Dec. 12, 2012 — A painstaking effort to create a biocompatible patch to heal infant hearts is paying off at Rice University and Texas Children’s Hospital. The proof is in a petri dish in Jeffrey Jacot’s lab, where a small slab of gelatinous material beats with the rhythm of a living heart Continue reading

High hormone levels put young black males at risk for cardiovascular disease

High hormone levels put young black males at risk for cardiovascular disease

ScienceDaily (Dec. 7, 2012) — Increased levels of the hormone aldosterone in young black males correlate with an unhealthy chain of events that starts with retaining too much salt and results in an enlarged heart muscle, researchers say. The findings indicate physicians may want to reach for aldosterone inhibitors early in their effort to control blood pressure and reduce cardiovascular risk in young black males. Continue reading

The birth of new cardiac cells: Where new heart cells come from

The birth of new cardiac cells: Where new heart cells come from

ScienceDaily (Dec. 5, 2012) — Recent research has shown that there are new cells that develop in the heart, but how these cardiac cells are born and how frequently they are generated remains unclear. In new research from Brigham and Women’s Hospital (BWH), researchers use a novel method to identify these new heart cells and describe their origins. Continue reading

Common drug increases deaths in atrial fibrillation patients

Common drug increases deaths in atrial fibrillation patients

ScienceDaily (Nov. 27, 2012) — Digoxin, a drug widely used to treat heart disease, increases the possibility of death when used by patients with a common heart rhythm problem − atrial fibrillation (AF), according to new study findings by University of Kentucky researchers Continue reading

Simplifying heart surgery with stretchable electronics devices

Simplifying heart surgery with stretchable electronics devices

ScienceDaily (Nov. 15, 2012) — Researchers at the McCormick School of Engineering are part of a team that has used stretchable electronics to create a multipurpose medical catheter that can both monitor heart functions and perform corrections on heart tissue during surgery. The device marks the first time stretchable electronics have been applied to a surgical process known as cardiac ablation, a milestone that could lead to simpler surgeries for arrhythmia and other heart conditions Continue reading

Call for fake medicine crackdown

Call for fake medicine crackdown

13 November 2012 Last updated at 20:03 ET By Michelle Roberts Health editor, BBC News online A global treaty to crack down on the deadly trade of fake medicines is urgently needed, say experts. Currently, there are more sanctions around the use of illegal tobacco than counterfeit drugs. Writing in the British Medical Journal 1 , experts urge the World Health Organization to set up a framework akin to its one tobacco control to safeguard the public. Continue reading
