Morbidity in newborns exposed to organophosphorus pesticides

Medicinski pregled, 2010
Introduction. Insecticides are toxines by which we destroy harmful insects. The most frequent insecticides which are used today are organophosphorus pesticides. This group of compounds make substances whose activity mechanism is based on the inhibition of acetylcho?linesterase in nerve synapsis, thus producing holynergic syndrome, resulting

Comparative Toxicological Study between Exposed and Non-Exposed Farmers to Organophosphorus Pesticides

Cell Journal, 2016
Objective: The purpose of this work was to compare DNA damage, acetylcholinesterase (AChE) activity, inflammatory markers and clinical symptoms in farmers exposed to organophosphorus pesticides to individuals that had no pesticide exposure.

Lysozyme-sensitive bioemulsifier for immiscible organophosphorus pesticides [PDF]

, 1986
Two Bacillus strains capable of emulsifying immiscible organophosphorus pesticides were isolated by enrichment methods. The emulsifying factor produced by Bacillus strain FE-2 has a high molecular weight, is Iysozyme sensitive and thermostable, and can ...

Genome-Wide Gene Expression Analysis in Response to Organophosphorus Pesticide Chlorpyrifos and Diazion in C.Elegans [PDF]

, 2010
pesticides (OPs) were originally designed to affect the nervous system by inhibiting the enzyme acetylcholinesterase, an important regulator of the neurotransmitter acetylcholine.

Nanoparticulate transport of oximes over an in vitro blood-brain barrier model [PDF]

, 2010
Background: Due to the use of organophosphates (OP) as pesticides and the availability of OP-type nerve agents, an effective medical treatment for OP poisonings is still a challenging problem.

Supercritical fluid extraction of organophosphorus pesticides from orange samples: Effect of solid additives on recovery [PDF]

, 1997
A method based on extraction with supercritical carbon dioxide has been developed for the analysis of pesticides in fruit. The method was tested on ten organophosphorus pesticides and dicloran in orange samples.
