Integrating dynamic mixed-effect modelling and penalized regression to explore genetic association with pharmacokinetics [PDF]

open access: yes, 2015
In a previous work, we have shown that penalized regression approaches can allow many genetic variants to be incorporated into sophisticated pharmacokinetic (PK) models in a way that is both computationally and statistically efficient.

Association between low body weight and cytochrome P-450 enzyme activity in patients with anorexia nervosa [PDF]

open access: yes, 2020
Very little is known to which extent severe underweight could affect cytochrome P-450 (CYP) enzyme activity. In this study, 24 patients with anorexia nervosa at two occasions ingested single oral doses of five test drugs known to be metabolized by CYP1A2,
