Studies on the role of moderate doses of ionizing radiation-induced cellular senescence in mouse lung tissue.

Purpose: To investigate the role of moderate doses of ionizing radiation-induced cellular senescence in mouse lung tissue and whole-body inflammation levels.

Material And Methods: Forty-two C57BL/6J mice were randomly divided into the control group, the 1, 3, and 7 days after 2 Gy irradiation group, and the 1, 3, and 7 days after 4 Gy irradiation group, with six mice in each group. The histopathology, cellular senescence, oxidative-antioxidant, DNA damage repair, and inflammation-related indicators of irradiated mice were examined.

Correlation analysis of occupational stress and metabolic syndrome among employees of a power grid enterprise in China.

Background: Being in a state of high occupational stress may disrupt the metabolic balance of the body, thus increasing the risk of metabolic diseases. However, the evidence about the relationship between occupational stress and metabolic syndrome was limited.

Objectives: To explore the association between occupational stress and metabolic syndrome (MetS) in employees of a power grid enterprise.

Correlation analysis between occupational stress and metabolic syndrome in workers of a petrochemical enterprise: based on two assessment models of occupational stress.

Background: Occupational stress is becoming a common phenomenon around the world. Being in a high occupational stress state for a long time may destroy the metabolic balance of the body, thereby increasing the risk of metabolic diseases. There is limited evidence regarding the correlation between occupational stress and metabolic syndrome (MetS), particularly in the petrochemical workers.

Functional analysis of polymorphism haplotypes of MGMT in residents of high background radiation area.

To investigate the distribution of polymorphisms and their frequent haplotypes in the regulatory region of MGMT in residents of high background radiation area (HBRA) and their impacts on transcriptional activity, we collected DNA samples from 83 healthy Chinese residents in HBRA and searched for genetic polymorphisms in the regulatory region of MGMT. Haplotypes were characterized by Haploview analysis. Transcriptional activities of different polymorphism haplotypes were detected by using a dual-luciferase reporter assay.

Analysis of occupational stress and its correlation with oxidative-antioxidant levels among employees of a power grid enterprise in Guangdong.

Background: Occupational stress and its health effects on occupational populations have attracted extensive attention from researchers in public health. The stressors faced by employees of power grid enterprises are increasing progressively, which is easy to cause occupational stress. The balance of the body's oxidative-antioxidant levels plays an essential role in maintaining the body's health status.
