A Novel Workflow for Fast Elucidation of Drug Metabolites for Screening—Combining In Silico Metabolite Prediction With Trapped Ion Mobility QTOF‐MS

Drug Testing and Analysis, EarlyView.
UHPLC‐timsTOF‐MS with in silico prediction and automated annotation enabled rapid identification of quetiapine metabolites from pHLMs, facilitating their inclusion in targeted LC‐QTOF‐MS urine screening and improving biomarker detection for toxicological applications.

Investigation of the In Vitro and In Vivo Metabolism and μ‐Opioid Receptor Affinity of the Nitazene N‐Pyrrolidino Fluetonitazene

Drug Testing and Analysis, EarlyView.
Eight metabolites for N‐pyrrolidino fluetonitazene were identified in vitro, three of which (M2, M6 and M8) were present in an authentic urine sample. M2 was the most abundant in vivo metabolite and is a common marker metabolite of nitazepyne‐type substances.

The high-resolution structure of the NADP(H)-binding component (dIII) of proton-translocating transhydrogenase from human heart mitochondria

, 2000
Background: Transhydrogenase, located in the inner membranes of animal mitochondria and the cytoplasmic membranes of bacteria, couples the transfer of reducing equivalents between NAD(H) and NADP(H) to proton pumping. The protein comprises three subunits

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

Equine Veterinary Journal, EarlyView.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Exploring Regorafenib Responsiveness and Uncovering Molecular Mechanisms in Recurrent Glioblastoma Tumors through Longitudinal In Vitro Sampling

Cells
Glioblastoma, a deadly brain tumor, shows limited response to standard therapies like temozolomide (TMZ). Recent findings from the REGOMA trial underscore a significant survival improvement offered by Regorafenib (REGO) in recurrent glioblastoma.

Proteomic signatures of equine dental tooth tissues in ageing and disease

Equine Veterinary Journal, EarlyView.
Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

Enviromics crosstalk between internal and external plant environments for enhanced adaptation and de novo domestication

iMeta, EarlyView.
Climate change demands accelerated plant adaptation and de novo domestication. Yet current enviromics focuses disproportionately on external environments, neglecting internal dynamics—gene expression, metabolic flux, and signal transduction—within predictive envirotyping frameworks.

A change in ionization of the NADP(H)-binding component (dIII) of proton-translocating transhydrogenase regulates both hydride transfer and nucleotide release

, 2001
Transhydrogenase couples the transfer of hydride-ion equivalents between NAD(H) and NADP(H) to proton translocation across a membrane. The enzyme has three components: dI binds NAD(H), dIII binds NADP(H) and dII spans the membrane.

Tiny carriers, big impact: How Fusobacterium nucleatum extracellular vesicles drive oral diseases and beyond

Interdisciplinary Medicine, EarlyView.
This review explores how Fusobacterium nucleatum extracellular vesicles drive local oral diseases and distal pathologies via sophisticated cross‐compartment cross talk. It highlights the transformative potential of these “tiny carriers” as next‐generation molecular intermediaries for advanced health monitoring and innovative bio‐interventions by ...
