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 ...

Anopheles arabiensis egg treatment with dieldrin for sex separation leaves residues in male adult mosquitoes that can bioaccumulate in goldfish (Carassius auratus auratus)

Environmental Toxicology and Chemistry, 2013
The sterile insect technique (SIT) is a biological control tactic that is used as a component of area‐wide integrated pest management (AW‐IPM) programs. The SIT can only be applied against disease‐transmitting mosquitoes when only sterile male mosquitoes

Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

Physiological Entomology, Volume 51, Issue 3, Page 526-536, September 2026.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

Epigenetic Mechanisms Underlying Cognitive Dysfunction in Parkinson's Disease: Current Evidence and Future Prospects

Brain and Behavior, Volume 16, Issue 8, August 2026.
Epigenetic mechanismsincluding DNA methylation, histone modifications, and microRNA (miRNA) regulationmodulate gene expression without altering the DNA sequence and are increasingly implicated in the cognitive impairment associated with Parkinson's disease (PD). Environmental and molecular factors influence these epigenetic pathways, leading to altered

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 ...

Pharmacodynamics of Dieldrin-C14 in Pheasants [PDF]

, 1969
The distribution, excretion, and metabolism of dieldrin-c14 in hen pheasants were studied. Eighteen laying hen pheasants were administered a gelatin capsule containing 1. 4 mg of dieldrin labelled with 5. 5 microcuries of carbon-14. Groups of three birds
