Male diabetics found to have lower levels of hydrogen sulfide in their blood

Hydrogen sulfide (H2S) is commonly associated with smell of rotten eggs, stink bombs and blocked drains but lower blood levels of the gas are possibly linked to cardiovascular complications in some male patients with type II diabetes, according to research recently presented by researchers at the Peninsula Medical School in the South West of England at the Annual Diabetes UK Professional Conference in Glasgow this week and published in Diabetic Medicine.

Novel genetic technology for canine form of muscular dystrophy

Using a novel genetic technology that covers up genetic errors, researchers funded in part by the National Institutes of Health have developed a successful treatment for dogs with the canine version of Duchenne muscular dystrophy, a paralyzing, and ultimately fatal, muscle disease.

Potential pathway for drug intervention

A newly identified molecular pathway that directs stem cells to produce glial cells yields insights into the neurobiology of Down's syndrome and a number of central nervous system disorders characterized by too many glial cells, according to a recent study by researchers at the Salk Institute for Biological Studies.

A natural immune response to HIV in exceptional patients

For 25 years, researchers have tried and failed to develop an HIV vaccine, primarily by focusing on a small number of engineered "super antibodies" to fend off the virus before it takes hold.

Scientists unveil a new path towards better immune responses

The immune response can protect us from basically any invader but it can also create disease - like it happens in autoimmunity where it attacks the own body - so to understand its regulation is an important tool to assure its proper functioning.

Study of Rituxan (rituximab) in lupus nephritis misses primary endpoint

Genentech, Inc. and Biogen Idec has announced that a Phase III study of Rituxan (rituximab) plus mycophenolate mofetil (MMF) and corticosteroids in patients with lupus nephritis did not meet its primary endpoint of significantly reducing disease activity at 52 weeks.

New test successfully identifies arrhythmogenic right ventricular cardiomyopathy

A study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has demonstrated that a new immunohistochemical test is reliable in diagnosing a dangerous arrhythmic heart disease known as arrhythmogenic right ventricular cardiomyopathy (ARVC.) Reported in the March 12 issue of The New England Journal of Medicine ( NEJM ), the new findings offer the possibility of a highly sensitive and specific means of identifying this life- threatening condition at an early stage, when it can be treated with by implanting a cardiac defibrillator.
