A genetic analysis of brain weights of 544 mice reared in either enriched or standard laboratory environments indicated significant directional dominance in the percentage of increase in brain weight as a result of enrichment.

Clostridium difficile toxins A and B are major virulence factors responsible for induction of pseudomembranous colitis and antibiotic-associated diarrhea in men. The toxins possess a multidomain structure and only the N-terminal glucosyltransferase domain, which inactivates Rho GTPases by glucosylation, is translocated into the cytosol of target cells. Processing of the toxin occurs by autocata...

Ebola virus (EBOV), which belongs to the genus Ebolavirus, causes a severe and often fatal infection in primates, including humans, whereas Reston virus (RESTV) only causes lethal disease in non-human primates. Two amino acids (aa) at positions 82 and 544 of the EBOV glycoprotein (GP) are involved in determining viral infectivity. However, it remains unclear how these two aa residues affect the...
