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.

DOI: 10.1016/j.psyneuen.2020.104704

Abstract: BACKGROUND Parkinson's disease (PD) and metabolic syndrome (MetS) share certain pathophysiological pathways, including hypothalamic pituitary adrenal (HPA) axis dysfunction. Hair glucocorticoid (GC) levels reflect longer-term HPA-axis function and can provide additional insights into the role… read more here.
