Abstract:

Muscle dysfunction in acute organophosphorus (OP) poisoning is a cause of death in human. The present study was conducted to identify the mechanism of action of OP in terms of muscle mitochondrial dysfunction. Electromyography (EMG) was conducted on rats exposed to the acute oral dose of malathion (400 mg/kg) that could inhibit acetylcholinesterase activity up to 70%. The function of mitochondrial respiratory chain and the rate of production of reactive oxygen species (ROS) from intact mitochondria were measured. The bioenergetic pathways were studied by measurement of adenosine triphosphate (

Abstract:

Objectives: Widely used organophosphorus pesticides, methyl parathion (MePa), alter the reproductive functions in various animals and humans by induction of oxidative stress on augmented release of reactive oxygen species (ROS). MePa affects semen quality by inducing DNA damage through spermatogenic stages. Several heat shock proteins (HSPs) are expressed in response to environmental stressors particularly the redox-active ones for regulation of protein turnover. Since oxidative stress and sperm motility are implicated in MePa toxicity, studying the expression of HSP90b will unravel the mechan

Abstract:

Background/Aim. Acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) are important biomarkers of exposure to organophosphorus and carbamate insecticides. Since the estimation of the level of cholinesterase inhibition depends on the normal values which may vary in different populations, it is important to determine them in our population, which so far has not been done. Therefore, the aim of this study was to determine the reference values for AChE and BuChE in a healthy population of adults in the Republic of Serbia. Methods. The AChE activity was measured by spectrophotometry (? = 41

Abstract:

Three-dimensional Quantitative Structure-Аctivity Relationship models were designed for irreversible and reversible acetylcholinesterase inhibitors by molecular modeling methods. In case of irreversible inhibitors CoMFA (the comparative analysis of molecular fields) or CoMSIA (the comparative analysis of indexes of molecular similarity) descriptors together with HYBOT 3D fields provide more statistically valid 3D-QSAR models. This indicates importance of donor-acceptor interactions for irreversible acetylcholinesterase inhibition. In case of reversible organophosphorous inhibitors good quality

Abstract:

Antibiotic misuse induces the production of antibiotic resistance genes (ARGs), leading to the global spread of antimicrobial resistance (AMR), which poses a major threat to human health. Conjugative transfer, as the main process of ARGs propagation, is sensitively influenced by coexisting contaminants. Chlorpyrifos and chlorpyrifos-methyl, as organophosphorus insecticides widely used in agriculture, have been shown to induce cytotoxicity such as elevated levels of reactive oxygen radicals (ROS) and lipid peroxidation. This is similar to the mechanism by which antibiotics promote the conjugati

Abstract:

Organophosphorus ligands are an invaluable family of compounds that continue to underpin important roles in disciplines such as coordination chemistry and catalysis. Their success can routinely be traced back to facile tuneability thus enabling a high degree of control over, for example, electronic and steric properties. Diphosphines, phosphorus compounds bearing two separated PIII donor atoms, are also highly valued and impart their own unique features, for example excellent chelating properties upon metal complexation. In many classical ligands of this type, the backbone connectivity has bee
