Health Biomarkers of Pesticide Exposure in Rural Populations of Santa Fe, Argentina: Oxidative Stress and Genotoxicity

Journal of Applied Toxicology, Volume 46, Issue 11, Page 3804-3813, November 2026.
ABSTRACT The present study aimed to quantify pesticide residues in environmental matrices and plasma and to evaluate their potential effects on oxidative stress and DNA damage in rural populations of Santa Fe province. Soil and rainwater samples were collected, and biological samples and semistructured surveys were obtained from volunteers in three ...

Pesticide Residues, Gut Microbiota, and Gastrointestinal Outcomes: A Scoping Review of Human Evidence

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Vegetables anchor healthy‐diet recommendations yet are the principal nonoccupational route by which residues of organophosphate (OP), pyrethroid, neonicotinoid, organochlorine (OC), and glyphosate herbicide enter the diet, with the gut microbiota a plausible mediator linking these residues to functional gastrointestinal (GI) and inflammatory ...

Efficient Red Light–Driven Singlet Oxygen Photocatalysis with an Osmium‐Based Coulombic Dyad

Angewandte Chemie, Volume 137, Issue 35, August 25, 2025.
Red light‐absorbing bichromophores with straightforward preparation and superior photocatalytic activity were developed. Spectroscopic studies provided deep insights into the intra‐ion‐pair energy transfer key step and the novel approach. Abstract Photoactive osmium complexes are widely used sensitizers for the generation of singlet oxygen because they

Electron‐Donating Multifunctional Molecules: A Strategy for High‐Performance Perovskite Solar Cells

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Multifunctional molecules containing electron‐donating groups are critically important in perovskite solar cells (PSCs), including defect passivation, crystallization modulation, energy level alignment, and other functions. This review systematically examines the application and research progress of such multifunctional molecules in PSCs ...

Antibacterial activity and mechanism of action of phosphonopeptides based on aminomethylphosphonic acid [PDF]

Antimicrobial Agents and Chemotherapy, 1982
Phosphonopeptides based on aminomethylphosphonic acid as the C-terminal residue linked to L-amino acids possessed antibacterial activity in vitro and in vivo. Analogs in this series were generally less potent than corresponding compounds based on L-1-aminoethylphosphonic acid such as alafosfalin (L-alanyl-L-1-aminoethylphosphonic acid).

Design of B,N Co‐Doped Carbon Spheres for Highly Effective Back Interface Engineering in Planar Carbon‐Based Perovskite Solar Cells

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
The energy level mismatch of the perovskite/carbon back interface is decreased remarkably by using B, N co‐doped carbon sphere electrode in C‐PSCs, leading to effective charge carrier separation, extraction, and transport at the back interface. Combined with further buried modification using AMPA, the power conversion efficiency of the C‐PSCs is up to ...
