Mapping Steroidogenic Perturbations Under Endocrine Disruptor Mixtures Across Demographic Subgroups: Structural and Metabolomic Insights

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Population‐scale EDC–hormone association mapping among 4255 participants across demographic subgroups identifies phthalate metabolites as the most consistent signals associated with lower testosterone‐related markers in males. Integrative mechanistic validation prioritizes MCPP as a key phthalate metabolite linked to CYP17A1‐centered disruption of ...

Advanced Sorbent Materials in Solid‐Phase Extraction: A Decade of Innovation and Future Perspectives

Chemistry–Methods, Volume 6, Issue 8, August 2026.
This review systematically summarizes five families of advanced sorbent materials for solid‐phase extraction (SPE): nanocarbons, porous frameworks (MOFs/COFs), smart polymers, biomass‐derived sorbents, and multifunctional composites. Key molecular interactions (π–π stacking, hydrogen bonding, electrostatic attraction, host–guest recognition) are ...

Maternal and infant gut microbiome

iMeta, Volume 5, Issue 4, August 2026.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Parabens in male infertility—Is there a mitochondrial connection? [PDF]

Reproductive Toxicology, 2009
Parabens are widely used as preservatives in many foods, cosmetics, toiletries, and pharmaceuticals due to their relatively low toxicity profile and to a long history of safe use. Parabens are alkyl esters of p-hydroxybenzoic acid and typically include methylparaben, ethylparaben, propylparaben, butylparaben, isobutylparaben, isopropylparaben and ...

Allergen Content of Inactive Ingredients in Best‐Selling Sunscreens: A Comparison of Key Product Features

Contact Dermatitis, Volume 95, Issue 2, Page 200-206, August 2026.
Allergenic risk of sunscreen active ingredients is well known, but that of inactive ingredients remains understudied. We identified and quantified allergens found in inactive ingredients of best‐selling sunscreens and developed a free tool (www.NAC80.com) that helps dermatologists recognise higher‐risk products and counsel patients prone to allergic or
