    Journal PapersEnvironmental Science and Pollution Research , 2021 February 1, {Pages 09-Jan }

    Abstract

    Acetamiprid (ACE) is one of the widely used neonicotinoid insecticides. In mammals, in spite of the low-affinity nAChRs, neurotoxic effects following the Acetamiprid exposure have recently been reported, which suggests some concerns regarding the impacts on the nervous system of mammals. This study aims to investigate the effect of Acetamiprid on spatial memory and possible vulnerability of hippocampal glutamatergic system following the Acetamiprid exposure. 10, 20, and 40 mg/kg doses of Acetamiprid were administered to male rats by gavage once per day for 28 days. The spatial memory was examined with the Morris water maze apparatus. The amount of Acetamiprid in the serum and hippocampus was measured. In addition, glutamate level and change

    Abstract

    Lead (Pb) is one of the most important heavy metals that possess many applications in different kinds of industrial procedures and consumer products. The adverse effects of Pb on different parts of the immune system have been reported in various studies. Although it has been shown that high concentrations of Pb have low cytotoxicity on human lymphocytes, the effects of non-cytotoxic concentrations of Pb (detected in human blood) on cellular organelles and oxidative stress factors of human lymphocytes have yet to be determined. In this study, human lymphocytes were obtained from the blood of healthy male volunteers through the use of the Ficoll standard method. The intention of this paper was to determine the effects of non-cytotoxic concent

    Journal PapersSpectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy , Volume 173 , 2017 February 15, {Pages 695-703 }

    Abstract

    A model was set up to predict the differentiation patterns based on the data extracted from FTIR spectroscopy. For this reason, bone marrow stem cells (BMSCs) were differentiated to primordial germ cells (PGCs). Changes in cellular macromolecules in the time of 0, 24, 48, 72, and 96?h of differentiation, as different steps of the differentiation procedure were investigated by using FTIR spectroscopy. Also, the expression of pluripotency (Oct-4, Nanog and c-Myc) and specific genes (Mvh, Stella and Fragilis) were investigated by real-time PCR. However, the expression of genes in five steps of differentiation was predicted by FTIR spectroscopy. FTIR spectra showed changes in the template of band intensities at different differentiation steps.

    Abstract

    Background and objectives: Alzheimer's disease (AD) as a neurodegenerative disorder is the most common form of dementia in the elderly. According to the amyloid hypothesis, accumulation of amyloid beta (Aβ) plaques, which are mostly constituted of Aβ peptide aggregates, triggers pathological cascades that lead to neuronal cell death. Thus, modulation of Aβ toxicity is the hopeful therapeutic approach for controlling the disease progression. Recently, several studies have indicated promising findings from herbal extracts against Aβ cytotoxicity. The aim of the present study was to assess the protective effect of the methanol extract of seven medicinal plants from Iran on Aβ-induced toxicity in primary neuron culture. Method: The methano

    Journal PapersEnvironmental toxicology , Volume 31 , Issue 11, 2016 November , {Pages 1510-1519 }

    Abstract

    Chlorpyrifos (CPF) is the most commonly used organophosphorus insecticide which causes neurodevelopmental toxicity. So far, animals have been used as ideal models for neurotoxicity studies, but working with animals is very expensive, laborious, and ethically challenging. This has encouraged researchers to seek alternatives. During recent years, several studies have reported successful differentiation of embryonic and adult stem cells to neurons. This has provided an excellent model for neurotoxicologic studies. In this study, neural differentiation of mouse adipose tissue‐derived stem cells (ADSCs) was used as an in vitro model for investigation of CPF neurotoxicity. For this purpose, mouse ADSCs were cultured in a medium containing knoc
