Statistical Discrimination of Urinary Steroid Biomarkers in the Athlete Biological Passport: A Novel Approach to an Abnormal Steroid Profile Score (ASPS)

open access: yesDrug Testing and Analysis, EarlyView.
The study developed a single Abnormal Steroid Profile Score (ASPS) to improve interpretation of the Athlete Biological Passport steroid module. Using Bayesian modelling and logistic regression, biomarker patterns from laboratory and doping control data successfully discriminated between doped and clean individuals, with improved classification ...

Experimental Investigation of Sensitivity for Coal and Gas Outburst Risk Prediction Indexes in Raw and Tectonic Composite Coal Seams

open access: yesEnergy Science &Engineering, EarlyView.
A comparative study was conducted on gas desorption laws of raw and tectonic coals. The sensitivity of regional and local outburst prediction indexes was compared. Gas content is more sensitive than gas pressure for composite coal seams. K1 can more accurately predict the outburst danger than Δh2 $\Delta {h}_{2}$ in composite coal seams.

Strong impact of sulfotransferases on DNA adduct formation by 4‐aminobiphenyl in bladder and liver in mice

open access: yesCancer Medicine, 2018
Bladder cancer risk is 3‐4 times higher in men than women, but the reason is poorly understood. In mice, male bladder is also more susceptible than female bladder to 4‐aminobiphenyl (ABP), a major human bladder carcinogen; however, female liver is more ...
