Blood-Brain Barrier Cellular Responses Toward Organophosphates: Natural Compensatory Processes and Exogenous Interventions to Rescue Barrier Properties

Frontiers in Cellular Neuroscience, 2018
Organophosphorus compounds (OPs) are highly toxic chemicals widely used as pesticides (e.g., paraoxon (PX)- the active metabolite of the insecticide parathion) and as chemical warfare nerve agents.

Fluorescent Silicate Materials for the Detection of Paraoxon [PDF]

Sensors, 2010
Porphyrins are a family of highly conjugated molecules that strongly absorb visible light and fluoresce intensely. These molecules are sensitive to changes in their immediate environment and have been widely described for optical detection applications.

The Experimental Oxime K027—A Promising Protector From Organophosphate Pesticide Poisoning. A Review Comparing K027, K048, Pralidoxime, and Obidoxime

Frontiers in Neuroscience, 2019
Poisoning with organophosphorus compounds (OPCs) is a major problem worldwide. Standard therapy with atropine and established oxime-type enzyme reactivators (pralidoxime, obidoxime) is unsatisfactory.

Chronic Consumption of Paraoxon Changes Thyroid Hormone Levels in Rats

Endocrinology Research and Practice, 2007
Objective: Paraoxon is an organophosphorus compound. These substances absorbed variously and inhibit acetylcholinestrase enzymes. The aim of this study was to investigate the effects of the chronic consumption of paraoxon on thyroid hormones.

Lipolysis generates platelet dysfunction after in vivo heparin administration [PDF]

, 2002
Heparin, when administered to patients undergoing operations using cardiopulmonary bypass, induces plasma changes that gradually impair platelet macroaggregation, but heparinization of whole blood in vitro does not have this effect.

Brief isoflurane administration as an adjunct treatment to control organophosphate-induced convulsions and neuropathology

Frontiers in Pharmacology, 2023
Organophosphate-based chemical agents (OP), including nerve agents and certain pesticides such as paraoxon, are potent acetylcholinesterase inhibitors that cause severe convulsions and seizures, leading to permanent central nervous system (CNS) damage if

Variation of Cholinesterase-Based Biosensor Sensitivity to Inhibition by Organophosphate Due To Ionizing Radiation

Sensors, 2009
A cholinesterase based biosensor was constructed in order to assess the effects of ionizing radiation on exposed AChE. Although the primary objective of the experiment was to investigate the effect of ionizing radiation on the activity of the biosensor ...
