Gut Microbiota, Immunity, and Metabolism in the Progression From Chronic Liver Disease to Hepatocellular Carcinoma

Advanced Science, Volume 13, Issue 44, 7 August 2026.
This review explains how chronic liver injury progresses toward hepatocellular carcinoma through interconnected changes in gut microbes, metabolism, immunity, fibrosis, and diet. It highlights microbial metabolites, bile‐acid signaling, immune dysfunction, and nutritional or microbiome‐based interventions as opportunities to identify risk earlier ...

Endogenous melatonin partial metabolic clearance as a potential endogenous marker of CYP1A2 activity

British Journal of Clinical Pharmacology, Volume 92, Issue 8, Page 2899-2908, August 2026.
Aims Cytochrome P450 1A2 (CYP1A2) exhibits substantial interindividual variability, necessitating appropriate phenotyping strategies for personalized pharmacotherapy. This study evaluated endogenous melatonin partial metabolic clearance (CLm(MEL)), calculated from urinary 6‐hydroxymelatonin (6‐O‐MEL) excretion and plasma melatonin (MEL) exposure, as a ...

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

Drug Testing and Analysis, Volume 18, Issue 8, Page 1097-1113, August 2026.
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.

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, Volume 18, Issue 8, Page 1036-1053, August 2026.
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.

In Vitro Metabolism of Δ8‐, Δ9‐, and Δ10‐THC in Human Hepatocytes: Distinct Δ10‐THC Biotransformation and Implications for Drug Testing

Drug Testing and Analysis, Volume 18, Issue 8, Page 1114-1121, August 2026.
Δ8‐THC and Δ9‐THC showed comparable metabolic profiles. In contrast, Δ10‐THC underwent extensive glucuronidation and hydroxylation, with only minor formation of a carboxy metabolite, indicating a markedly different metabolic pathway. These differences may increase the risk of misidentification and misinterpretation in cannabis drug testing.

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, Volume 18, Issue 8, Page 1145-1151, August 2026.
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.

Gluten‐Free Cakes With Locusta migratoria as a Protein Source: Volatile Profile, Quality, Nutritional, and Sensory Attributes

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
This study evaluated the effects of locust powder (LP) and defatted locust powder (DFLP), used as rice flour substitutes at 10%, 15%, and 20% levels, on volatile profile, quality, nutritional, microbiological, and sensory properties of gluten‐free (GF) cakes.
