Metallurgy is a major economic branch in Russia with more than 4000 enterprises operating it and seventy percent of them being city-forming ones. This study focuses on cytological assessment the oral mucosa secretion from middle meatus workers employed metallurgy. The aim this was to investigate laboratory indicators metallurgy under exposure adverse occupational factors. A clinical diagnostic ...

INTRODUCTION: Micronuclei (MN) are microscopically visible round or oval cytoplasmic chromatin masses in the extra nuclear vicinity, originating from aberrant mitosis, chromatic fragments or whole chromosomes. The local factors like smoking exerts an influence on oral mucosa cells which are reflected as cellular changes resulting in the formation of MN. AIM: To evaluate and compare the MN index...

With tremendous advances made in the field of molecular biology techniques, the analysis of genomic DNA has become a matter of routine. However, there is a growing need for better, cost-effective, non-invasive methods for sample collection and DNA extraction. A simple protocol for sample collection and extraction of high molecular weight genomic DNA from buccal cells in mouthwash has been stand...

Air pollution has been recognized as a human carcinogen. Children living in urban areas are a high-risk group, because genetic damage occurring early in life is considered able to increase the risk of carcinogenesis in adulthood. This study aimed to investigate micronuclei (MN) frequency, as a biomarker of DNA damage, in exfoliated buccal cells of pre-school children living in a town with high ...

Pesticides are one of the main inputs in agricultural activities; however, their exposure has been linked to generation various health effects. Today, many studies show ability pesticides induce genotoxic damage. The aim this study was evaluate level damage workers from Vicente Guerrero-Tlaxcala community, Mexico, exposed pesticides. composed by 50 Guerrero community and 16 non-exposed individu...

background: the cells of mammalian female reproductive tract have been widely used for in vitro fertilization (ivf). this study was designed to study the effects of oviductal epithelial cells (oecs) and their conditioned medium during ivf on subsequent embryonic development and the relative abundance of zygote arrest 1 (zar1) transcript in ovine zygotes. methods: the in vitro matured ovine oocy...

BACKGROUND To study cytological alterations in the exfoliated buccal cells of diabetic patients. To analyze the cytomorphometric findings in the smears of uncontrolled and controlled diabetic patients and compare it with that of normal healthy controls. To establish a correlation between cytomorphometric changes and glycosylated hemoglobin (HbA1c) in diabetics and normal controls, for evaluatio...
