While the regulatory guidelines that describe the validation requirements for small molecules are very comprehensive, they are written primarily for xenobiotic drug molecules. However, the presence of endogenous analyte in control matrix presents an added analytical challenge that must be

The round goby, Neogobius melanostomus, is a highly successful invasive species in the Laurentian Great Lakes. Previous behavioral studies implied that females are attracted by pheromones to the nests of reproductive males, and that males release putative steroidal pheromones--unconjugated as

The survival and progression of prostate cancer are generally dependent on expression of the androgen receptor (AR), as well as the availability of endogenous AR agonists. Originating from the gonads, testosterone is released into circulation and is converted by steroid-5α-reductase

Steroids enantiomers are interesting compounds for detailed exploration of drug metabolizing enzymes, such as the UDP-glucuronosyltransferases (UGTs). We have now studied the glucuronidation of the enantiomers of estradiol, androsterone and etiocholanolone by the 19 human UGTs of subfamilies 1A, 2A

In the cardiac setting in pediatrics, inotropic support is often employed based on the extrapolation from adult studies, the underlying pathophysiology, pharmacodynamics of inotropes, and anecdotal experience. Large pediatric critical care studies involving inotropic support are rare. Levosimendan, a calcium-sensitizing
