The chalcone (E)-1-(2-hydroxyphenyl)-3-(4-methylphenyl)-prop-2-en-1-one), or 2HMC, displays antileishmanial, antimalarial, and antioxidant activities. The aim of this study was to investigate the cytotoxic, genotoxic, mutagenic, and protective effects of 2HMC using the Ames mutagenicity test, the mouse bone marrow micronucleus test, and the comet assay in mice. In the assessment using the Ames ...

Increasing applications of microwave radiation are of great concern with regard to public health. Several studies have been conducted detect effects of microwave exposure genetic material leading to negative or questionable results. The Micronucleus (MN) assay which is proved to be a useful method for detection of radiation exposure-induced cytogenetic damage was used in the present study to in...

The fuel properties of the solid product obtained from hydrothermal carbonization (HTC) are substantially influenced by interaction reactions lignocellulose components. This study focused on cellulose and hemicellulose (represented glucose xylose, respectively) formation mechanism hydrochar through experiments density functional theory methods. Results indicated that furfural was main intermedi...

The aim of this experiment was to investigate whether static magnetic fields (SMFs) have cytogenetic effects in mouse bone marrow cells. The frequency of micronuclei was significantly increased by exposure of mice to 3.0 T for 48 and 72 h and 4.7 T for 24, 48 and 72 h. The increase in micronucleus frequency was dose dependent at all times. Micronucleus frequency at 4.7 T was higher than at 3.0 ...

Background: Although initial studies on Elaeagnus Angustifolia L. Fruit Extract (Senjed) Nanocapsule showed its efficacy in osteoporosis in rat model as well as its significant role in elevating the serum calcium levels, there is no study on its possible genotixic potentials which is necessary for developing all nanopharmaceuticals. Objective: This study aimed to evaluate the genotoxicity of Se...

The anti-parasitic benzimidazole flubendazole has been used for many years to treat intestinal infections in humans and animals. Previous genotoxicity studies have shown that the compound is not a bacterial mutagen and a bone marrow micronucleus test, using a formulation that limited systemic absorption, was negative. The purpose of this study is to explore the genotoxicity of flubendazole and ...

Programmed genome rearrangements in ciliates provide fascinating examples of flexible epigenetic genome regulations and important insights into the interaction between transposable elements (TEs) and host genomes. DNA elimination in Tetrahymena thermophila removes approximately 12 000 internal eliminated sequences (IESs), which correspond to one-third of the genome, when the somatic macronucleu...

background: stress may cause damages to dna or/and change the ability of the cells to overcome these damages. it may also cause irregularities in the cell cycle and induce abnormal cell divisions through glucocorticoid-dependent functions. the abnormal cell divisions, in turn, lead to chromosomal mal-segregation and aneuploidy. in this study, the effects of the stress hormone, hydrocortisone (h...
