Physiologically‐based pharmacokinetic modelling of uridine 5′‐diphosphoglucorosultransferase (UGT) substrate drugs in pregnant women

British Journal of Clinical Pharmacology, EarlyView.
Aims While pregnancy‐related changes in phase I enzyme activity are well‐documented, less is known about the impact on phase II enzymes. This study aimed to test the hypothesis that changes in the pharmacokinetics (PK) of uridine 5′‐diphosphoglucuronosyltransferase (UGT) substrates during pregnancy result from altered enzyme expression or activity ...

Constantes de acidez de ácidos dipróticos a partir de titulações potenciométricas: ilustração dos princípios do cálculo através da construção de um algoritmo muito simples

Química Nova, 2011
This work describes the creation of an very simple calculation algorithm, based in basic chemical and mathematic principles, for the calculation of weak diprotic acid dissociation constants as, for example, amino acids, from potentiometric titrations ...

Nicotinamide Reverses the Warburg Effect in CHO Cell Culture

Biotechnology and Bioengineering, EarlyView.
Abstract The Warburg effect, the preferential conversion of glucose‐derived pyruvat to lactate despite available oxygen, is a key feature of Chinese hamster ovary (CHO) cell culture. Lactate accumulation in recombinant protein‐producing cell culture is an inefficient usage of glucose, as well as being deleterious to cells.

Dried blood spot analysis in antidoping: Technical challenges, analytical advances, and future perspectives

Bulletin of the Korean Chemical Society, EarlyView.
Dried blood spot (DBS) analysis enables minimally invasive blood collection with strong analyte stability and simplified logistics, supporting anti‐doping applications beyond traditional matrices. Recent advances address hematocrit, volume variability, and matrix effects while expanding coverage to steroid esters, World Anti‐Doping Agency‐listed ...

Bioenhancer‐Driven Modulation of Membrane Dynamics Improves B‐Vitamin Uptake in Caco‐2 Cells

ChemFoodChem, EarlyView.
Natural bioenhancers such as extracts from ginger, turmeric, black pepper, and spearmint increase the uptake of vitamins B1, B5, B6, and B7 in Caco‐2 cells. Micellized formulations further increase efficacy. These findings indicate that altered membrane fluidity contributes to enhanced cellular absorption, providing a new route to improve vitamin B ...

Pharmacokinetic Evaluation of a Cinnamon Product on CYP2A6 Substrate Drugs: Application of a Novel Tool Involving the Nicotine Metabolite Ratio

Clinical Pharmacology &Therapeutics, EarlyView.
Cinnamon (Cinnamomum spp.) is used as a culinary spice and dietary supplement. A major constituent, cinnamaldehyde, was previously shown to inactivate cytochrome P450 (CYP) 2A6 in vitro. A mechanistic static model predicted an ~5‐fold increase in the AUC of the CYP2A6 substrates nicotine and letrozole.

Denosumab Offers Relatively Lower Initial Protection Against Osteoporotic Vertebral Fractures in Treatment‐Naive Patients Compared With Zoledronate

Clinical Pharmacology &Therapeutics, EarlyView.
We compared the initial efficacy of denosumab (Dmab) and zoledronate (ZOL) in treatment‐naive patients with osteoporosis. This cohort study, based on TriNetX data, evaluated the risks of fractures and mortality using Kaplan–Meier survival analyses, with hazard ratios (HRs) and 95% confidence intervals (CIs).

Genomic Insights Into Risperidone Treatment Outcomes in Children and Adolescents: Experience From a Psychiatric Hospital Serving Rural Youth

Clinical Pharmacology &Therapeutics, EarlyView.
Risperidone is a commonly used antipsychotic for treating psychiatric illness in children and adolescents. There is a large variability in risperidone response and discontinuation rates remain high. Pharmacogenomics offers the opportunity to improve risperidone outcomes, yet studies in pediatric populations are limited.
