O boala autoimuna in care sistemul imunitar distruge trombocite. Distrugerea trombocite duce la anormale de sânge coagulare şi uşor sau excesive vânătaie şi sângerări. Exact cauza trombocitopenie idiopatică vasculara este necunoscut; cu toate acestea, pot dezvolta tulburare cu o infecţie virală, inclusiv HIV.

Concentrazione di una sostanza in un mezzo ambientale che provoca la morte dopo un certo periodo di esposizione.
Industry:Biology; Chemistry
Concentrazione di una sostanza in un'unica fase diviso per la concentrazione della sostanza nella fase di altre quando il sistema eterogeneo delle due fasi è in equilibrio.
Nota 1: Il rapporto tra le concentrazioni (o, in senso stretto, attività) della stessa specie molecolare nelle due fasi è costante a temperatura costante.
Nota 2: Il coefficiente di ripartizione ottanolo/acqua è spesso usato come una misura del fattore di bioconcentrazione per scopi di modellazione.
Nota 3: Questo termine è di uso in tossicologia comune ma non è raccomandato dalla IUPAC per uso in chimica e non dovrebbe essere usato come sinonimo per partizione costante, il rapporto di partizione o rapporto di distribuzione.

1) Syntetiske udskrifter af et specifikt DNA molekyle eller fragment, foretaget af et in vitro transskription system. Denne cRNA kan være navngivet med radioaktivt uracil og bruges derefter som en sonde.
2) Enkeltstrenget RNA hvis base sekvens er et supplement til specifikke DNA sekvenser (fx gener) eller mere sjældent, en anden enkeltstrenget RNA; normalt videregiver en kunstig hybridisering sonde eller antisense genetiske inhibitor.
Industry:Medical
A water-soluble, enzyme co-factor present in minute amounts in every living cell. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk.
Industry:Health care
Artificially constructed cloning vector containing the cos gene of phage lambda. Cosmids can be packaged in lambda phage particles for infection into E. coli; this permits cloning of larger DNA fragments (up to 45kb) than can be introduced into bacterial hosts in plasmid vectors.

UV radiation. Invisible rays that are part of the energy that comes from the sun. UV radiation can damage the skin and cause melanoma and other types of skin cancer. UV radiation that reaches the earth's surface is made up of two types of rays, called UVA and UVB rays. UVB rays are more likely than UVA rays to cause sunburn, but UVA rays pass deeper into the skin. Scientists have long thought that UVB radiation can cause melanoma and other types of skin cancer. They now think that UVA radiation also may add to skin damage that can lead to skin cancer and cause premature aging. For this reason, skin specialists recommend that people use sunscreens that reflect, adsorb, or scatter both kinds of UV radiation.
