Body mass index may play a significant role in the progression of multiple sclerosis

Obesity and a higher body mass index negatively impacts the progression of Multiple Sclerosis. Ceramides are more abundant in the blood of those who are overweight. The ceramides enter inside the nucleus of monocytes, causing proliferation. The increased number of monocytes travel back to the brain, causing more damage for those with RRMS.

Epigenetics Contributes to Male and Female Differences in Fear Memories

A new mouse study reveals males recall fearful memories better than females. Researchers attribute the difference to the gene Cdk5, which has previously been implicated in creating fear memories and stress behaviors. The study reports Cdk5 is naturally activated in males, but not females.
