Changing trends in anabolic‐androgenic steroid use within Scottish prisons: Detection, prevalence, and quantitation

open access: yesDrug Testing and Analysis, Volume 17, Issue 6, Page 858-867, June 2025.
This study reports the qualitative and quantitative detection of anabolic‐androgenic steroids (AASs) in seized samples from prisons. Since 2022 there has been an increase in AAS detections with oxymetholone the most prevalent AAS, followed by metandienone, methyltestosterone, and oxandrolone.

Implication of human UGT2B7, 2B15 and 2B17 in 19-norandrosterone metabolism

open access: yesFrontiers in Endocrinology, 2013
Nandrolone (19-nortestosterone) is an anabolic androgenic steroid commonly abused for doping purposes. Nandrolone is mainly metabolized in the liver into 19-norandrosterone prior to glucuronidation and excretion through urine over an extended period of ...

Comparative Analysis of Primary Sarcopenia and End‐Stage Renal Disease–Related Muscle Wasting Using Multi‐Omics Approaches

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 2, April 2025.
ABSTRACT Background Age‐related primary sarcopenia and end‐stage renal disease (ESRD)–related muscle wasting are discrete entities; however, both manifest as a decline in skeletal muscle mass and strength. The etiological pathways differ, with aging factors implicated in sarcopenia and a combination of uremic factors, including haemodialysis ...
