Identifying an Active Intermediate and Monitoring O─O Bond Formation in Water Oxidation by a Cobalt(III)‐TAML Complex

Angewandte Chemie International Edition, EarlyView.
Two redox tautomers of a cobalt–TAML complex show strikingly different reactivity in water oxidation. The ligand‐centered Co(III)–OH species evolves O2 via H2O2, while the metal‐centered Co(IV) = O is inactive. Electron‐transfer kinetics and the Marcus analysis reveal how redox localization influences reactivity and O─O bond formation in high‐valent ...

Determination of selenium speciation in the muscle, kidney, and liver from different animals treated with different selenium supplements by HPLC‐ICP‐MS

Animal Research and One Health, EarlyView.
Dietary selenium (Se) deficiency is recognized as a global problem, and exogenous Se supplementation can effectively enrich its levels in animal bodies. Offal tissues are equally important as meat in Se enrichment. Varying properties among Se species require information beyond total Se concentration to fully evaluate health risk/benefits.

Metabolic fate of drugs of abuse and new psychoactive substances: A pilot study on a novel workflow using a zebrafish embryo model combined with human microdosing

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...

Probability of pharmacokinetic/pharmacodynamic target attainment for different piperacillin/tazobactam dosing regimens in renally impaired patients in a non‐intensive care unit setting

British Journal of Clinical Pharmacology, EarlyView.
Aims To optimize antibiotic therapy for pathogens classified as susceptible, increased exposure (I), an increased exposure of piperacillin/tazobactam (PTZ) is required. However, dosing recommendations are currently only available for patients with normal renal function.
