Gene variant raises risk for aortic tear, rupture

Gene variant raises risk for aortic tear, rupture

Researchers from Yale School of Medicine and Celera Diagnostics have confirmed the significance of a genetic variant that substantially increases the risk of a frequently fatal thoracic aortic dissection or full rupture. The study appears online in PLOS ONE . Thoracic aortic aneurysms, or bulges in the artery wall, can develop without pain or other symptoms Continue reading

Outcome of stroke worse for people with infection

Outcome of stroke worse for people with infection

Infection is bad news for all of us — but it can be really serious to people who have had a stroke. Evidence is mounting that infection makes things much worse after a stroke. A team of scientists at the University of Manchester has now found a key to why and how infection is such a bad thing for stroke sufferers. Continue reading

Lifelong premature ejaculation can be treated by pelvic floor exercises

Lifelong premature ejaculation can be treated by pelvic floor exercises

A trial presented at the European Congress of Urology in Stockholm reports for the first time that pelvic floor exercises can be effective in treating premature ejaculation in men who have had lifelong problems. Premature Ejaculation (PE) affects a significant minority of men at some point in their lives. Continue reading

Online registry to drive brain disease research

Online registry to drive brain disease research

A new online project led by researchers at UC San Francisco promises to dramatically cut the time and cost of conducting clinical trials for brain diseases, while also helping scientists analyze and track the brain functions of thousands of volunteers over time. With easy online registration, the Brain Health Registry is designed to create a ready pool of research subjects for studies on neurological diseases, such as Alzheimer’s and Parkinson’s, as well as depression, post-traumatic stress disorder and many other brain ailments.

Light-activated neurons from stem cells restore function to paralyzed muscles

Light-activated neurons from stem cells restore function to paralyzed muscles

A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists at UCL and King’s College London. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches Continue reading

Patient stem cells help identify common problem in ALS

Patient stem cells help identify common problem in ALS

Harvard stem cell scientists have discovered that a recently approved medication for epilepsy may possibly be a meaningful treatment for amyotrophic lateral sclerosis (ALS) — Lou Gehrig’s disease, a uniformly fatal neurodegenerative disorder. The researchers are now collaborating with Massachusetts General Hospital to design an initial clinical trial testing the safety of the treatment in ALS patients. The investigators all caution that a great deal needs to be done to assure the safety and efficacy of the treatment in ALS patients, before physicians should start offering it Continue reading

Call for circumcision gets a boost from experts

Call for circumcision gets a boost from experts

In the United States the rate of circumcision in men has increased to 81% over the past decade. In an important new study just published in advance in Mayo Clinic Proceedings authors from Australia and the United States have shown that the benefits of infant male circumcision to health exceed the risks by over 100 to 1. Brian Morris, Professor Emeritus in the School of Medical Sciences at the University of Sydney and his colleagues in Florida and Minnesota found that over their lifetime half of uncircumcised males will contract an adverse medical condition caused by their foreskin.
