One of the most toxic effects of organophosphate (OP) poisoning has been the paralysis of skeletal muscles that can lead to paralysis of respiratory muscles and death. However, oximes are the only antidotes available to reverse or prevent such toxic effects of OP insecticides and nerve chemical warfare agents. In the present research work, the effect of different concentrations of paraoxon (as ...

In this work, the ability of four newly synthesized oximes--K005 (1,3-bis(2-hydroxyiminomethylpyridinium) propane dibromide), K027 (1-(4-hydroxyiminomethylpyridinium)-3-(4-carbamoylpyridinium) propane dibromide), K033 (1,4-bis(2-hydroxyiminomethylpyridinium) butane dibromide) and K048 (1-(4-hydroxyiminomethylpyridinium)-4-(4-carbamoylpyridinium) butane dibromide) to reactivate acetylcholinester...

Mandarin Resultative Verb Compounds (RVCs) are verbal complexes of the form V1-V2, where V1 denotes an activity and V2 the result of that activity. Previous literature either assigns to RVCs a Complex Verb structure [V V1-V2] (Li 1990, Williams 2012) or a Small Clause structure [V1P V1 [SCV2]] (Sybesma 1999). In the paper, I will propose a VP Complementation syntax for Mandarin RVC [V1P V1 [V2P...

BACKGROUND Our study sought to assess the effectiveness of a constant micropump infusion of atropine and pralidoxime chloride compared with repeated-bolus doses in patients with severe acute organophosphorus insecticide poisoning (AOPP). METHODS A total of 60 patients with severe AOPP, defined as cholinergic crisis with respiratory failure or cerebral edema, were randomly divided into two gro...

Intermediate syndrome is not an uncommon condition, it may occur following exposure to organophosphates, either accidental or suicidal. Picture of intermediate can develop within 24 96 h. We report the case a 41-year-old male patient, who had picture syndrome, occurring with delayed onset, than usual, after insecticide solution containing organophosphates. stress that patients have recovered fr...

Organophosphorus poisoning caused by some pesticides and nerve agents is a life-threating condition that must be swiftly addressed to avoid casualties. Despite the availability of medical countermeasures, clinically available compounds lack broad spectrum, are not effective towards all organophosphorus toxins, have poor pharmacokinetics properties allow them crossing blood-brain barrier, hamper...

Due to human activities, the concentrations of organometallic compounds in all parts of the environment have increased in recent decades. The toxicity and some biochemical properties of mercury and tin present in the environment depend on the concentration and chemical form of these two elements. The ever-increasing demand for determining compounds at very low concentration levels in samples wi...

Organotin compounds are chemicals composed of tin linked to hydrocarbons, used in industrial materials and various biocides and fungicides. As a result, organotin compounds can enter the environment through a number of channels, and can often be found in seawater, seafood, fruits and vegetables, and consumer goods. Due to the toxicity of these compounds, there is a need for analytical methods a...

Montmorillonite K-10 functionalized with α-nucleophilic 2-pralidoxime (PAM) and its zwitterionic oximate form (PAMNa) is introduced as a versatile material for chemical protection against organophosphorous (OP) compounds such as pesticides and chemical warfare agents (CWA). Upon inclusion into the montmorillonite interlayer structure, the pyridinium group of PAMNa is strongly physisorbed onto a...

Studies of human cases of self-inflicted poisoning suggest that chlorpyrifos oxon reacts not only with acetylcholinesterase and butyrylcholinesterase but also with other blood proteins. A favored candidate is albumin because in vitro and animal studies have identified tyrosine 411 of albumin as a site covalently modified by organophosphorus poisons. Our goal was to test this proposal in humans ...
