DOI: 10.1007/s00216-018-1131-6
Abstract: AbstractHair samples are increasingly used for measuring the long-term stress mediator cortisol. However, hair is not always available and nails (finger or toe), as a keratinized matrix, may be an alternative to hair. In order… read more here.

DOI: 10.1016/j.jpba.2017.03.039
Abstract: &NA; Cortisol (F) and cortisone (E) are metabolized to A‐ring reduced metabolites in the reactions catalyzed by 5&agr;‐ and 5&bgr;‐reductase. 5&agr;‐tetrahydrocortisol (alloTHF) and 5&bgr;‐tetrahydrocortisol (THF) are produced from F. The metabolism of E takes place… read more here.
