Objective(s): This study focused on determining cytotoxic effects of copper oxide nanoparticles (CuO NPs) on chronic myeloid leukemia (CML) K562 cell line in a cell-specific manner and its possible mechanism of cell death. We investigated the cytotoxicity of CuO NPs against K562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). Materials and Methods: The toxicity w...
Background: Exposure to ionizing radiation results in genotoxicity and the unrepaired lesions in cellular DNA results in cell cycle arrest, reproductive death, interphase death, division delay, chromosome aberrations, mutations, etc. leading to the intensive destruction of cells and violation of their proliferative capacity there by adversely affecting the mammalian system. Since ionizing radia...
Silicon (Si) has not been considered as an essential nutrient for plant growth however, it has been shown that supplying crops with adequate Si can improve environmental stress tolerance. On the other hand, exposure to toluene, as a hazardous organic pollutant widely found in the water resources, is an environmental stress for plants growing around many industries. The aim of this nutrient solu...
Background & Aims: Frequent administration of morphine leads to increase in motor activity, motivational properties, and other responses related to this kind of drugs. It has been reported that the impact of morphine on seizure is dose dependent. The aim of this study was to study the impact of chronic exposure to morphine on pentylenetetrazol-induced seizure in rats. Materials & Methods: Neon...
Objective(s): In this study, we desvcribe a simple eco-friendly approach for the synthesis of a potent, stable and benign silver nanoparticles to carry and deliver chalcones and dihydrochalcones present in a methanol extract of Eysenhardtia polystachya (EP). Materials and Methods: In this process silver nanoparticles carring EP compounds (EP/AgNPs) are synthesized in a single step by eliminatin...
Background: Epilepsy is one of the most common neurological diseases globally. Mast cells are known to be the main source of brain histamine, which is identified as being involved in seizure modulation. Sodium cromoglycate is a popular mast cell stabilizer and is proposed as the first line therapy in chronic asthma and systemic mastocytosis. Considering the importance of gestational period in ...
Introduction: Doxorubicin is frequently used for treatment of several types of cancer. Doxorubicin cardiac toxicity has limited the use of this drug. Corticosteroids may prevent doxorubicin induced cardiotoxicity. Therefore the aim of this study was to evaluate mouse embryonic stem cells derived cardiomyocytes as a model to evaluate the effect of Doxorubicin and dexamethasone. Methods: Mouse ...
Introduction: It has been shown that mobile radiations (MRs) have detrimental effects on brain histoarchitecture and vitamin E as a powerful antioxidant can exhibit neuroprotective effects. This study was carried out to evaluate the protective effects of vitamin E against MRs-induced histological changes in rat brain. Methods: Adult female Wistar rats were randomly categorized into 4 groups (n...
Glutamate induces excitotoxic damage to hippocampal pyramidal neurons in Status Epilepticus (SE) and epilepsy. In this study, we investigated time course of dysregulation of calcium homeostasis at various intervals after an episode of SE in acutely isolated CA1hippocampal pyramidal. For this purpose, male Sprague-Dawley rats (200 g) were subjected to pilocarpine-induced SE. The SE was blocked a...
Background: Chamomile essential oil (CEO) hauls out from Matricaria chamomilla L., is a well-known anti-oxidant. Oxidative stress induces clastogenic and biochemical disorders after γ-irradiation of animals. Materials and Methods: Mice were divided into five groups. Control group received vehicle only. &nbs...
