Experiments on the mode of action of dieldrin seed-dressings against seedling attack by the larval frit fly, oscinella frit l

open access: yes, 1959
Experiments with dieldrin seed-dressings were done to see whether the conditions favouring their action against wheat bulb fly larvae apply also to frit fly.

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

open access: yesBrain 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

open access: yesChemistry–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 ...

Determination of Dieldrin and Polychlorinated Biphenyls in Seawater by Solid Phase Extraction and Capillary Gas Chromatography

open access: yesYankuang ceshi, 2014
Dieldrin and polychlorinated biphenyls (PCBs) are toxic, organic pollutants that break down extremely slowly in the marine environment. Therefore, it is of valuable significance to establish a rapid, sensitive and accurate detection method for dieldrin ...

An Interaction of Dieldrin with Thiamine

open access: yesExperimental Biology and Medicine, 1968
SummaryA dietary level of 20 ppm of dieldrin increased growth in rats raised on rations containing low levels of thiamine, or conversely, the low dietary intake of thiamine produced a smaller growth depression in rats ingesting dieldrin. There was a marked variation among litters in their response to the nutritional stress and the dieldrin produced a ...
