nociceptory

Peripheral AFFERENT NEURONS which are sensitive to injuries or pain, usually caused by extreme thermal exposures, mechanical forces, or other noxious stimuli. Their cell bodies reside in the DORSAL ROOT GANGLIA. Their peripheral terminals (NERVE ENDINGS) innervate target tissues and transduce noxious stimuli via axons to the CENTRAL NERVOUS SYSTEM.

nokodazol

Nocodazole is an antineoplastic agent which exerts its effect by depolymerizing microtubules.
MSH

A synthetic tubulin-binding agent with antineoplastic activity. Nocodazole binds to beta-tubulin and disrupts microtubule assembly/disassembly dynamics. This prevents mitosis and induces apoptosis in tumor cells. Although nocodazole binding site overlaps with that of colchicine, the two agents are structurally quite different.

hluk

Any sound which is unwanted or interferes with HEARING other sounds.
MSH

undesired sound, especially a random mix of different frequencies.
CSP

Any part of a signal that is not the true or original signal but is introduced by the communication mechanism.
NCI

Noise is all around you, from televisions and radios to lawn mowers and washing machines. Harmful sounds – sounds that are too loud or loud sounds over a long time – can damage sensitive structures of the inner ear and cause noise-induced hearing loss.

More than 30 million people in the U.S. are exposed to hazardous sound levels on a regular basis. Hazardous sound levels are louder than 80 decibels, which isn`t as loud as traffic on a busy street. Listening to loud music, especially on headphones, is a common cause of noise-induced hearing loss. Keeping the volume down when listening to music and wearing earplugs when using loud equipment can help protect your hearing.

noma

A severe gangrenous process occurring predominantly in debilitated and malnourished children, especially in underdeveloped countries. It typically begins as a small vesicle or ulcer on the gingiva that rapidly becomes necrotic and spreads to produce extensive destruction of the buccal and labial mucosa and tissues of the face, which may result in severe disfigurement and even death. Various bacteria have been implicated in the etiology. (Dorland, 27th ed)
