Specialists from the University of South Florida have carried out a study in mice. The researchers have found that CyP40 enzyme protected the neurons of the experimental animals. It also relieved rodents of cognitive impairment and disintegrated the alpha-synuclein protein deposits associated with Parkinson's disease, Zee News reports.

A new study performed by the scientists of Helmholtz Munich Center has shown that infections occurred during the first year of life may cause celiac disease (gluten intolerance) at a later age. Most of all, the risk is increased due to GI infections, Zee News reports.

Obsessive-compulsive disorder (OCD) is characterized by the manifestations of involuntary obsessive thoughts (obsessions) and attempts to get rid of them through compulsive actions (compulsions).

Scientists from the National Institutes of Health of the United States have found that glutamine supplements (one of the 20 standard amino acids involved in the protein) prevent the reactivation of herpes simplex virus (HSV).
