Analysis of anabolic androgenic steroids in urine by full-capillary sample injection combined with a sweeping CE stacking method.
Anal. Bioanal. Chem 405(6) , 1969-76, (2013) This study describes an on-line stacking CE approach by sweeping with whole capillary sample filling for analyzing five anabolic androgenic steroids in urine samples. The five anabolic steroids for detection were androstenedione, testosterone, epitestosterone... |

UDP-glucuronosyltransferase 2B17 genotyping in Japanese athletes and evaluation of the current sports drug testing for detecting testosterone misuse.
Drug Test. Anal. 5(3) , 166-81, (2013) Ethnicity has been found to influence urinary testosterone glucuronide to epitestosterone glucuronide (T/E) ratios among athletes. Uridine diphospho-glucuronosyltransferase 2B17 (UGT2B17) is the most active enzyme in testosterone glucuronidation. UGT2B17 poly... |
