Long‐term demography and spatial genetic structure reveal mechanisms of Sassafras albidum population persistence through clonality

open access: yesAmerican Journal of Botany, Volume 113, Issue 6, June 2026.
Abstract Premise Vegetative regeneration is a key mechanism of woody plant persistence in forest ecosystems, and the coupled roles of basal sprouting and clonal growth in shaping long‐term population dynamics have been understudied. Basal sprouting replaces stems at fixed ramet locations, whereas clonal growth via root suckering produces spatially ...

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

open access: yesJournal of Applied Toxicology, Volume 46, Issue 6, Page 1987-2002, June 2026.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Quaternary ammonium salt derivatives of allylphenols with peripheral analgesic effect

open access: yesMemorias do Instituto Oswaldo Cruz, 1991
Ammonium salt derivatives of natural allylphenols were synthesized with the purpose of obtaining potential peripheral analgesics. These drugs, by virtue of their physicochemical properties, would not be able to cross the blood brain barrier.

Unlocking the Hepatoprotective Potential of Cyperus rotundus Through Edible Vinegar Processing: A Study on Functional Ingredient Enhancement

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
Cyperus rotundus L. (CR) and vinegar‐processed CR (VCR) were compared in mouse models of thioacetamide (TAA)‐induced acute and chronic liver injury. VCR exhibited better hepatoprotective effects than raw CR. Composition analysis revealed 35 components in VCR, among which α‐cyperone was present at higher levels than in raw CR.

Multi‐Target Mechanisms of Moroccan Aphrodisiac Plants: An Integrative Computational and Phytochemical Investigation

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
Moroccan medicinal plants with in silico‐approved aphrodisiac effects provide 94 phytochemicals. Docking against PDE5, AR, ERα, and aromatase gives top scores for lutein (−10.6), baicalein (−9.5), liquiritigenin (−9.2), and procyanidins (−9.7). ADMET filtering passes baicalein and liquiritigenin but excludes lutein and procyanidins. MD simulations (200
