Genetic markers linked to the start of symptoms of Parkinson's disease

Researchers have identified a group of genetic variants related to the starting point of Parkinson's disease. These results, published in the journal Movement Disorders, will enable delimiting the research on new therapeutic targets, and could have implications in the diagnosis of the disease.

'Relaxed' enzymes may be at the root of Charcot-Marie-Tooth disease

So far, mutations on more than 90 genes have been positively linked to the disorder; a patient needs just one of those mutations for the disease to emerge. Scientists just moved a step closer to finding a possible root cause.

Three-in-one inhaler therapy can improve lung function and reduce asthma attacks

Patients with severe asthma which is not controlled with standard treatment — leaving them at risk of severe asthma attacks — could benefit from using a single inhaler combining three, instead of 2 therapies, according to two phase 3 randomized controlled trials with over 2,500 patients across 17 countries.

Early life racial discrimination linked to depression, accelerated aging

Early life stress from racial discrimination puts African Americans at greater risk for accelerated aging, a marker for premature development of serious health problems and perhaps a shorter life expectancy, according to a new study.

Curbing diesel emission could reduce big city mortality rate

US cities could see a decline in mortality rates and an improved economy through midcentury if federal and local governments maintain stringent air pollution policies and diminish concentrations of diesel freight truck exhaust, according to new research.
