Confirmation of Pesticide Residue Identity. VIII. Organophosphorus Pesticides

Journal of AOAC INTERNATIONAL, 1974
Abstract A chemical confirmation for 5 organophosphorus pesticides is described. After extraction and quantitation by flame photometric detector gas-liquid chromatography (CLC), the organophosphorus pesticides are hydrolyzed in a 10% methanolic-potassium hydroxide solution, followed by derivatization with pentafluorobenzyl bromide to ...

Predicting outcome using butyrylcholinesterase activity in organophosphorus pesticide self-poisoning [PDF]

, 2008
Background: The usefulness of a low butyrylcholinesterase (BuChE) activity on admission for predicting severity in acute organophosphorus (OP) insecticide poisoning has long been debated. Previous studies have been confounded by the inclusion of multiple

Self injection of Dichlorvos, an Organophosphorus Compound [PDF]

, 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.

Household organophosphorus pesticide use and Parkinson’s disease [PDF]

International Journal of Epidemiology, 2013
Household pesticide use is widespread in the USA. Since the 1970s, organophosphorus chemicals (OPs) have been common active ingredients in these products. Parkinson's disease (PD) has been linked to pesticide exposures but little is known about the contributions of chronic exposures to household pesticides.

Quantitative Proteomics and CRISPR/Cas9 Editing Reveal UPR‐Mediated Control of Immunoglobulin Homeostasis in Hybridomas

Advanced Science, EarlyView.
BCR sequencing and subclone analysis correlated immunoglobulin (Ig) chain loss in dysfunctional hybridomas with disrupted monoclonal antibody homeostasis. Proteomics‐guided CRISPR/Cas9 editing revealed that the unfolded protein response (UPR) regulates aberrant Ig synthesis.
