OBJECTIVE To review the public health significance of organophosphate pesticide exposure in the United States of America. Since the situation of high organophosphate pesticide exposure and the concomitant health risks in the developing countries of the world is well known, this article seeks to highlight the public health significance of organophosphate exposure in the United States, where it i...

introduction: organophosphate compounds are used as insecticides, nerve gases, ophthalmic agents, and antihelmintics.the primary mechanism of action of organophosphate pesticides is inhibition of acetylcholinesterase (ache). however  pralidoxim has been introduced as organophosphate `s antidote but recent studies establish that pralidoxim has unclear benefit in treatment of organophosphate pois...

The control of the cattle tick Rhipicephalus microplus is based mainly on the use of chemical acaricides, which has contributed to the emerging problem of selection of resistant tick populations. Currently, there are six main classes of acaricides commercially available in Brazil to control cattle ticks, with fluazuron, a tick growth regulator with acaricidal properties, being the only active i...

The use of synthetic acaricides for management of pest mites may alter the efficacy of the ectoparasitoid Tamarixia radiata (Waterston) in biological control of Diaphorina citri Kuwayama, the vector of the bacteria associated with huanglongbing (HLB) in citrus orchards. We evaluated the toxicity of 16 acaricides that are recommended for the control of citrus-pest mites to T. radiata. Acrinathri...

Ticks are responsible for transmitting viral, bacterial, and protozoal diseases to humans animals also cause significant economic damage the livestock industry. The owner of farmhouse prefers use acaricides, a key component tick control strategies. However, indiscriminate irresponsible acaricides has detrimental effect on increase in contamination environment, acaricide resistance ticks, its re...

Organophosphate pesticides are widely used and recent studies suggest associations of in utero exposures with adverse birth outcomes and neurodevelopment. Few studies have characterized organophosphate pesticides in human plasma or established how these levels correlate to urinary measurements. We measured organophosphate pesticide metabolites in maternal urine and chlorpyrifos and diazinon in ...

BACKGROUND Many patients with organophosphate poisoning require mechanical ventilation. Muscle acetylcholinesterase (AChE) activity determines the impairment of muscle force generation, and red blood cell (RBC) AChE has been regarded as a surrogate for muscle AChE in organophosphate poisoning. Therefore, this study was conducted to investigate whether RBC AChE at presentation can predict the du...

introduction: compounds which are used to treat organophosphate (op) poisoning are not able to fully alleviate long lasting effects. they are mainly used to antagonize cholinergic effects of ops. however, non-cholinergic effects, such as interference with different neurotransmitter systems, especially gaba release and uptake, are recently attracting more attentions. we have tried to investigate...
