background: occupational exposure to excessive level of copper results in many adverse health effects. objective: to measure pulmonary function, oxidative stress, and extent of dna damage in workers of a copper processing industry. methods: 30 men working in a copper processing industry and 30 men matched for age and socioeconomic status (comparison group) were included in this study. pulmonary...

Mitochondria plays a major role in maintaining homeostasis of heart cells. Mitochondria produce ATP and is the main intracellular source of reactive oxygen species (ROS) which can cause oxidative damage. Free oxygen radicals and oxidative damage are associated with cardiovascular pathology. Antioxidant defense can play an essential role in preventing oxidative damage by controlling free oxygen ...

introduction: some studies have suggested correlation between mpv index and inflammatory diseases such as rheumatoid arthritis in adults. though bronchopulmonary dysplasia is also an inflammatory disease which develops in preterm neonates with respiratory distress syndrome, we decided to study the possible correlation between the mean platelet volume (mpv) and the occurrence of bronchopulmonary...

objective(s): exposing to stress may be associated with increased production of reactive oxygen species (ros). therefore, high level of oxidative stress may eventually give rise to accumulation of oxidative damage and development of numerous neurodegenerative diseases. it has been presented that brain-derived neurotrophic factor (bdnf) supports neurons against various neurodegenerative conditio...

Background: The terms Reactive Oxygen Intermediates or Reactive Oxygen Species (ROS) are used to describe the molecules as highly reactive oxygen molecules that will chemically oxidize neighboring susceptible molecules. A prominent feature of radicals is that they have extremely high chemical reactivity, which explains not only their normal biological activities, but how they inflict damage on ...

A major concern on the application of sewage sludge in agricultural lands is relatively high cadmium (Cd) concentrations in these wastes which might be toxic to the plant and causes oxidative damage. Much higher Zn concentration in sewage sludge in comparison with cadmium may affect oxidative damage induced by cadmium. The aim of the present study was to investigate the effects of various conce...

Background: Single nucleotide polymorphisms in 8-oxoguanine DNA glycosylase-1 (OGG1) gene modulates DNA repair capacity and functions as one of the first lines of protective mechanisms against 8-hydroxy-2’-deoxyguanosine (8-OHdG) mutagenicity. OGG1-Cys326 gene polymorphism may decrease DNA repair function, causing oxidative stress due to higher oxidative DNA damage. The main purpose of this stu...
