Researchers [39] suggest that because variation in drug use susceptibility is in part due to genetic factors, drug consumption could potentially be a costly and honest signal of biological quality. [ 40 ] [ 41 ] The hypothesis being that humans engage in substance use despite health costs in part to evidence that they can afford to do so.
The smallpox vaccine is used to prevent smallpox infection caused by the variola virus. [10] It is the first vaccine to have been developed against a contagious disease.

Biologics can refer to a wide range of biological products in medicine. However, in most cases, the term is used more restrictively for a class of therapeutics (either approved or in development) that are produced using biological processes involving recombinant DNA technology. These medications are usually one of three types:
It's like one side of the zipper keeps getting longer, while the other doesn't. Even in people with the mutation, it usually takes decades for these mistakes to accumulate and CAG to reach 150 ...
“The brain changes, and it doesn’t recover when you just stop the drug because the brain has been actually changed,” Kreek explained. “The brain may get OK with time in some persons. But it’s hard to find a person who has completely normal brain function after a long cycle of opiate addiction, not without specific medication treatment.”
