A ubiquitous skin-dwelling organism that is involved in causing acne.
The complete genome of this bacterium was sequenced and analyzed in 2004, providing insights into the bacterial antigens and tissue-damaging enzymes that may cause the inflammatory reactions underlying acne. The genome sequence also clearly revealed many proteins involved in the ability of P. acnes to colonize and reside in skin sites as well as its pronounced potential to survive in a spectrum of environments. This capacity helps to explain the ubiquity of P. acnes and also its potential hazards, for example, in contaminating units of blood in blood banks.
a prescription sedative-hypnotic drug (brand name Diprivan) that is administered intravenously. Propofol is commonly used in the induction of general anesthesia and can be used both for the induction and maintenance of general anesthesia. When administration of the drug is discontinued, it wears off rapidly, allowing the patient to awaken within a short time. Like […]
- Proportional counter
A device for measuring radioactivity. More technically, a proportional counter counts the emission of radioactive particles which permits the discrimination between particles or rays of different energies.
A female through whom a family medically comes to light (is first ascertained). Also called the proband or index case. The male counterpart of a proposita is a propositus.
The initial subject presenting a mental or physical disorder, who causes a study of his or her heredity in order to determine if other members of the family have had the same disease or carry it. Also called index case and proband.
The ability to sense stimuli arising within the body regarding position, motion, and equilibrium. Even if a person is blindfolded, he or she knows through proprioception if an arm is above the head or hanging by the side of the body. The sense of proprioception is disturbed in many neurological disorders. It can sometimes be […]
