Monitoring resistance of Cydia pomonella (L.) Spanish field populations to new chemical insecticides and the mechanisms involved [PDF]

open access: yes, 2017
BACKGROUND: A widespread resistance of Cydia pomonella to organophosphates was demonstrated in populations from the Spanish Ebro Valley area that showed high levels of enzymatic detoxification.

Durable Physically Mixed Microporous and Mesoporous MOFs/Nanofiber Aerogel 3D Composites for Effective Toxic Gas Capture and Organophosphonate Detoxification

open access: yesAdvanced Functional Materials, EarlyView.
Ultralight 3D nanofibrous aerogels embedded with metal‐organic frameworks effectively capture and neutralize toxic gases and organophosphonates. Incorporating mesoporous UiO‐66‐NH2 and HKUST‐1 into PAN/PVP fibers enables high MOF loading while maintaining mechanical strength and structural stability.

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]

open access: yesActa 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.

Losing the ‘arms race’: multiresistant salmon lice are dispersed throughout the North Atlantic Ocean

open access: yesRoyal Society Open Science, 2021
Nothing lasts forever, including the effect of chemicals aimed to control pests in food production. As old pesticides have been compromised by emerging resistance, new ones have been introduced and turned the odds back in our favour.

Self injection of Dichlorvos, an Organophosphorus Compound [PDF]

open access: yes, 2008
We report two patients who injected themselves a strong organophosphate compound, dichlorvas, and showed the typical clinical picture of organophosphate intoxication. There are very few case reports of parenteral organophosphorous poisoning.

Mimicking Block Copolymer Self‐Assembly with One‐Pot Synthesized Polyphosphoester Gradient Copolymers

open access: yesAdvanced Functional Materials, EarlyView.
Degradable Polyphosphoester (PPE) gradient copolymers (GCPs) are synthesized via one‐pot copolymerization. We show that GCPs self‐assemble into nanostructures like polymersomes, effectively mimicking the behavior of traditional BCPs. The gradient strength is key, with softer gradients favoring micelles.

Aedes aegypti resistance to temephos during 2001 in several municipalities in the states of Rio de Janeiro, Sergipe, and Alagoas, Brazil

open access: yesMemorias do Instituto Oswaldo Cruz, 2004
For more than 30 years temephos, an organophosphate insecticide, has been the sole larvicide used in Brazil in the control of Aedes aegypti. Organophosphates were also used for adult control, being replaced by pyrethroids since l999.

Subcutaneous injection of organophosphate (Fenitrothion)—Management of preventing the appearance of toxic symptoms: A case report

open access: yesClinical Case Reports, 2021
There is a risk of unnecessary extensive incision because of swelling after the subcutaneous injection; however, removing completely the injected organophosphate by making a skin incision before the appearance of toxic symptoms could reduce sequelae.
