For the study, researchers screened the oligoadenylate synthetase (OAS1) gene in 401 people with MS, 394 people without MS and 178 people receiving the MS treatment beta interferon.
On the analysis of the OAS1 gene, 63 percent of people with MS had the AA genotype compared to 57 percent of people without MS. The GG genotype was found in 37 percent of people with MS compared to 43 percent of people without the disease.
While the OAS1 gene was weakly associated with disease susceptibility, the study found that people who had the AA genotype had earlier relapses and increased disease activity compared to those without the genotype.
“While we don’t understand why some patients vary so widely in their disease activity, this genetic association may give us clues to help direct future research,” said study author Margaret O’Brien, PhD, with St. Vincent’s University Hospital in Dublin, Ireland.
The study also found people who had the GG genotype had less disease activity and fewer relapses. “It’s possible that the GG genotype may protect against increased disease activity in people with MS, but more research is needed,” said O’Brien.
The study was supported by Science Foundation Ireland, the Health Research Board of Ireland and MS Ireland.
The American Academy of Neurology, an association of more than 22,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Parkinson’s disease, ALS (Lou Gehrig’s disease), dementia, West Nile virus, and ataxia.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
