The magnetic properties of the YFe(12-x)M(x) compounds (M = Ti, Mo or V; x = 1-3.5) have been determined in the ordered ferromagnetic state as well as in the paramagnetic state. The iron magnetic moment has been determined from 4 K up to the Curie temperature whereas the analysis of the paramagnetic region has led to the determination of the effective iron magnetic moment. The number of spins h...

Lithium cyclopentadienides are important reagents for the synthesis of organometallic compounds. In addition they feature an interesting manifold of structural variations in solution and in the crystal [1]. Variable temperature NMR spectroscopy has revealed markedly temperature dependent equilibria between monomeric lithium cyclopentadienides and their respective lithiocene salts [2]. A typical...

Organophosphate (OP) compounds are frequently used agorchemicals for deliberate self-harm in some parts of the world resulting in high mortality and morbidity. Pralidoxime (2PAM) is the most widely used and trialed oxime for treatment of OP poisoning. There have been variations over the results of trials using 2PAM for OP poisoning. 2PAM therapy has led to favorable outcomes in some studies, wh...

Acetylcholinesterase has important role in synaptic cleft. It breaks down the acetylcholineat cholinergic synapsesand terminates the cholinergic effects. Some chemical agents like organophosphorus compounds (OPCs) including nerve agents and pesticides react with acetylcholinesteraseirreversibly. They inhibit normal biological enzyme action and result in accumulation of acetylcholineand show tox...

Prophylactic and therapeutic efficacy against organophosphorus (OP) intoxication by pralidoxime (2-PAM) and atropine were studied and compared with sterically stabilized long-circulating liposomes encapsulating recombinant organophosphorus hydrolase (OPH), either alone or in various specific combinations, in paraoxon poisoning. Prophylactic and therapeutic properties of atropine and 2-PAM are d...

General concepts concerning models, their logical and analogical status, are briefly outlined. The use of compartmental models to simulate the kinetics of compounds in the environment is illustrated by a discussion of carbon dioxide in the atmosphere and oceans and its uptake by plants. The application of compartmental models to the kinetics of organochlorine compounds in vertebrates and in eco...

Background: The effective therapeutic dose of pralidoxime methylsulphate for organophosphate (OP) poisoning is necessary to be clarified. This study was designed to comparatively assess the blood level of pralidoxime (BPL) and clinical outcomes in OP poisoned patients treated with intermittent dosing and patients treated with continuous infusion. Methods: This was a prospective, open labelled, ...
