Phase I Metabolism of Novel Phencyclidine Derivative 3‐Cl‐PCP: In Vitro Studies With Pooled Human Liver Microsomes and Investigation of a Post‐Mortem Case

Drug Testing and Analysis, EarlyView.
A fatal 3‐chloro‐phencyclidine (3‐Cl‐PCP) intoxication was investigated by analyzing postmortem samples and a pooled human liver microsomes assay. Tentative metabolite identification was performed by liquid chromatography‐quadrupole time‐of‐flight mass spectrometry (LC‐QTOF‐MS). Seven phase I metabolites were identified.

Investigations Into the Metabolism and Elimination of Tesofensine in Human Urine

Drug Testing and Analysis, EarlyView.
This study investigated tesofensine metabolism and urinary elimination after a single 483 μg intake via a dietary supplement. In six volunteers, urine was collected up to 659 h. LC‐HRMS/MS identified four tentative metabolites; maximum urinary concentrations reached 4 ng/mL within 4–48 h.

Identification of Synthetic Urine by Analysis of Stable Carbon and Nitrogen Isotope Ratios and Comparison to Established GC‐MS/MS and LC‐MS/MS Analysis

Drug Testing and Analysis, EarlyView.
This study compared GC‐MS/MS, EA‐IRMS, and LC‐MS/MS for detecting synthetic and manipulated urine samples in doping control and forensic analysis. EA‐IRMS proved particularly effective for identifying mixtures of synthetic and authentic urine, providing a reliable complement to established authenticity testing methods.

Cannabidiol in Anorexia Nervosa: A Double‐Blind Randomized Placebo Controlled Pilot Study to Test Safety, Pharmacokinetics, and Symptom Change

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a severe psychiatric disorder marked by an intense fear of gaining weight and persistent body dissatisfaction, both during periods of underweight and after weight restoration. The endocannabinoid system may offer therapeutic benefits, particularly in reducing anxiety.

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

Strategies for Identification and Mitigation of Sanguinarine in Mustard Oil Adulterated by Argemone—A Comprehensive Review

Food Chemistry International, EarlyView.
Sanguinarine, a toxic alkaloid present in argemone, can lead to epidemic dropsy or chronic diseases through DNA intercalation and immune system suppression. Regulatory efforts face challenges due to economic motivations for adulteration as well as technical, social, and infrastructure barriers.

Evaluation of sunn hemp performance and nutritive value in Maine, USA

Grassland Research, EarlyView.
Abstract Background Sunn hemp (Crotalaria juncea L. and Crotalaria ochroleuca G. Don) was evaluated as a warm‐season legume to mitigate the “summer slump” in Maine's forage production caused by heat and moisture deficit stress. Methods This study compared three cultivars: “Crescent Sunn,” “Loei,” and “Red Mini,” at 60 and 90 days after seeding over the
