Fusion inhibitor
Fusion inhibitor: A class of antiretroviral drugs that work on the outside of the host CD4 cell to prevent HIV from fusing with and infecting it. Fusion inhibitors act by binding to an envelope protein and blocking the structural changes necessary for the virus to fuse with the host CD4 cell. If HIV cannot penetrate the host cell membrane and infect the cell, HIV cannot replicate within the host cell.

Fourth cranial nerve: The fourth cranial nerve, the trochlear nerve, is the nerve supply to the superior oblique muscle of the eye, one of the muscles that moves the eye. Paralysis of the trochlear nerve results in rotation of the eyeball upward and outward (and, therefore, double vision). The twelve cranial nerves, the trochlear nerve […]

Fournier’s gangrene: A horrendous infection of the genitalia that causes severe pain in the genital area (in the penis and scrotum or perineum) and progresses from erythema (redness) to necrosis (death) of tissue. Gangrene can occur within hours. The mortality (death) rates are up to 50%. In this major medical emergency, a bacterial infection spreads […]
