Partial protection from organophosphate-induced cholinesterase inhibition by metyrapone treatment [PDF]

open access: yes, 2013
Background: Organophosphates are cholinesterase (ChE) inhibitors with worldwide use as insecticides. Stress response, evidenced by a dramatic and relatively long-lasting (several hours) rise in the plasma glucocorticoid concentration is an integral ...

Self‐Assembled Crystalline Peptoid Nanomaterials as Metal‐Free Enzyme Mimics for Enhanced Carbon Dioxide Hydration and Precipitation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.

Organophosphate Hydrolase in Conductometric Biosensor for the Detection of Organophosphate Pesticides [PDF]

open access: yesAnalytical Chemistry Insights, 2015
The research has developed an enzyme biosensor for the detection organophosphate pesticide residues. The biosensor consists of a pair of screen-printed carbon electrode (SPCEs). One of electrodes contains immobilized organophosphate hydrolase (OPH) on a chitosan membrane by cross-linking it with glutaraldehyde.

RBM25 Drives Hepatocellular Carcinoma Progression by Stabilizing YAP Through Regulating Oncogenic Splicing‐switch of MYPT1

open access: yesAdvanced Science, EarlyView.
This study establishes that the RBM25‐PRPF40A interaction modulates MYPT1 splicing, promoting the production of the oncogenic long isoform. This isoform stabilizes YAP by suppressing its phosphorylation and subsequent proteasomal degradation, ultimately accelerating tumor growth.

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.

Exposures and health effects among field workers using the organophosphate chlorpyrifos [PDF]

open access: yes, 2004
Chlorpyrifos, an organophosphate pesticide moderately toxic to humans via inhalation and dermal absorption (LD50 oral, rat = 226 mg kg-1, LD50 skin, rabbits = 1265 mg kg-1), is widely used to eradicate termites in Australia.
