Intravenous organophosphate injection: an unusual way of intoxication.

, 1997
Organophosphate insecticides strongly inhibit both true cholinesterase and pseudocholinesterase activities. In this report, we have reported a patient who injected himself a strong organophosphate compound, methamidophos, and showed the typical clinical ...

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...

Inhibition of Muscle-Specific Protein Kinase (MuSK) Releases Organophosphate-Aged Acetylcholinesterase (AChE) from C2C12 Cells

Toxics
Mechanistically, OPs inhibit acetylcholinesterase (AChE), an enzyme that terminates cholinergic transmission, triggering a sustained activation of acetylcholine receptors.

Crystal structure and catalytic activity of tetrakis(μ2-ethyl 2,6-di-tert-butyl-4-methylphenyl phosphato-κ2O:O′)bis(ethyl 2,6-di-tert-butyl-4-methylphenyl phosphato-κ2O,O′)dilutetium n-heptane disolvate

Acta Crystallographica Section E: Crystallographic Communications, 2018
The title complex, [Lu2(C17H28O4P)6]·2C7H16, was formed in the reaction between potassium 2,6-di-tert-butyl-4-methylphenyl ethyl phosphate, [K(2,6-tBu2-4-MeC6H2-O)(EtO)PO2], and LuCl3(H2O)6 in water, followed by vacuum drying and recrystallization from ...

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Organophosphate poisoning in pregnancy

Journal of Obstetrics and Gynaecology, 2011
Organophosphate poisoning during pregnancy is rarely reported in the literature. In our retrospective study, we report the outcome of 21 cases of organophosphate poisoning during pregnancy. All patients received atropine injection until the tracheobronchial tree is cleared of the secretions and most secretions were dried.

Cooperative Regulation of Defect‐Mediated Molecular Recognition With Single‐Walled Carbon Nanotubes

Small, EarlyView.
Defect‐mediated sensing in SWCNTs arises from the cooperative interplay of defect characteristics, density, heterogeneity, analyte properties, corona composition, and environment. Understanding these interconnected variables enables tunable fluorescence modulation, selective molecular recognition, ratiometric sensing, and sensitive detection in complex

Updated Adulticide Susceptibility Status of Florida Populations of Aedes aegypti (Linnaeus, 1762)

Pathogens
Insecticide resistance in Aedes aegypti (Linnaeus, 1762) poses a major challenge for vector control programs, undermining the effectiveness of chemical tools to mitigate both nuisance biting and the transmission of vector-borne diseases. Previous studies

Morpho-toxicology of chlorpyrifos to prolactin cells of a freshwater catfish, Heteropneustes fossilis =Morpho-toxicology of chlorpyrifos to prolactin cells of a freshwater catfish, Heteropneustes fossilis [PDF]

Acta Scientiarum: Biological Sciences, 2012
In the present study, an organophosphorus compound Coroban (active ingredient chlorpyrifos – E.C. 20%) was used. In short-term exposure the fish were subjected to 0.8 of 96h LC50 value of chlorpyrifos (1.76 mg L-1) for 96h.
