Drug tests, secret

Supreme Court Strikes Down Secret Hospital Drug Testing... 

Organism-on-chip will include functions ranging from substance uptake, to metabolism, to secretion and will consider interaction and interdependence of different organs. The question is, however, whether organism-on-chip can be realized reproducibly enough to be useful in practical applications such as drug testing. 

You ve come on a good day, said Dr. Kimura. We re running another test with a drug called EA 2277. I suddenly realized I was about to enter a new world full of secret names and numbers. 

P-glycoprotein-mediated efflux is a potential source of pecuHarities in drag pharmacokinetics, such as non-Hnearity. This includes dose-dependent absorption, drug-drag interactions, intestinal secretion and limited access to the brain. Assays are in development to quantify the interaction between transporters and drugs. One of the first is a 96-weU plate assay for P-gp binding [33, 34] and an MDRl ATPase test [35]. 

The resin secreted by Cannabis indica and Cannabis sativa, varieties of hemp, is known variously as marijuana, hashish or bhang and is abused as a hallucinogenic drug. It appears however to have some beneficial properties and is currently under test as an antiemetic in cancer therapy. The secretion contains a number of interrelated oxygen heterocycles, some of which are shown in Scheme 281, which attempts to indicate their biosynthetic relationships (70MI22401). The cannabinoids are probably derived from a monoterpene unit based on p-menthane and 5-n-pentylresorcinol (olivetol), acting the part of a polyketide. 2,2-Dimethylchromene biosynthesis also requires the intervention of an isoprene fragment.
