MeSH

Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.

Culture media containing biologically active components obtained from previously cultured cells or tissues that have released into the media substances affecting certain cell functions (e.g., growth, lysis).

The middle layer of blood vessel walls, composed principally of thin, cylindrical, smooth muscle cells and elastic tissue. It accounts for the bulk of the wall of most arteries. The smooth muscle cells are arranged in circular layers around the vessel, and the thickness of the coat varies with the size of the vessel.

Inflammation of the middle ear with purulent discharge.

Year introduced: 1991(1979)

Inflammation of the middle ear with a clear pale yellow-colored transudate.

Year introduced: 1986

Inflammation of the MIDDLE EAR including the AUDITORY OSSICLES and the EUSTACHIAN TUBE.

Instruments or technological means of communication that reach large numbers of people with a common message: press, radio, television, etc.

Year introduced: 1980

Substances used to allow enhanced visualization of tissues.

Problematic, compulsive Internet use that results in significant impairment of person's function in daily life.

Year introduced: 2021

A tear or separation of the layers by a blood vessel typically involving vessels under pressure, i.e., ARTERIES, e.g., AORTA. Tearing of the TUNICA INTIMA layer of a blood vessel may lead to interstitial HEMORRHAGE. Dissection between the tunica intima and TUNICA MEDIA causes luminal occlusion. Dissection at the media, or between the media and the outer ADVENTITIA causes aneurismal dilation.

Year introduced: 2023

Social media model for enabling public involvement and recruitment in participation. Use of social media to collect feedback and recruit volunteer subjects.

Year introduced: 2013
