Occupational exposure to metal fumes occurs routinely in many occupational settings. The inflammatory response to fumes and metals after exposure could lead to an increase in reactive oxygen species and level of DNA damage. In this study, the level of early DNA damage and oxidative stress was evaluated in a group of steel company (n = 30) and compared to the …

[Oxidative Stress Level of Vanadium-exposed Workers].

The differences in oxidative stress level between vanadium-exposed and non-exposed workers were compared. RESULTS: Vanadium-exposed workers had higher levels of MDA contents than the controls. The total superoxide dismutase(T-SOD) activity in vanadium-exposed workers was significantly lower than that in the controls, which was associated with ...

Oxidative stress and copper smelter workers - ScienceDirect

Oxidative stress and copper. Physiologically, oxidative stress can be defined as a condition created by an oxidation/elimination of electrons that creates an oxidizing compound with potential toxicity. 30 Cells have a specific antioxidant system that protects them from these oxidizing agents by utilizing some decoy compounds (i.e., glutathione ...

A possible case of pneumoconiosis in a limestone quarry …

Oxidative stress and cytotoxicity elicited by chalk PM2.5 were also examined. The results showed that fine chalk particles were mainly composed of gypsum, calcite, dolomite and …

Biomarkers of oxidative stress and DNA damage in ...

Apurinic/apyrimidinic endonuclease (APE) is one of the key steps of the base excision repair (BER) pathway (Sokhansanj et al., 2002) (see also Fig. 1) and is induced in cells by oxidative stress (Edwards et al., 1998, Hsieh et al., 2001, Ramana et al., 1998).We developed a unique oligonucleotide probe for assessing APE activity in lymphocytes of agricultural workers.

Oxidatively damaged DNA in the nasal epithelium of …

Therefore, we conducted a cross-sectional study to evaluate the prevalence of 3-(2-deoxy-β-D-erythro-pentafuranosyl)pyrimido[1,2-α]purin-10(3H)-one deoxyguanosine (M1dG) adducts, a biomarker of oxidative stress and peroxidation of lipids, in the nasal epithelium of 135 silica-exposed workers, employed in pottery, ceramic and marble ...

Inflammatory and oxidative stress parameters as potential ...

Therefore, considering the actual context of workers exposed to crystalline silica and the lack of an early way to diagnose silicosis, this study aimed to investigate inflammatory and oxidative stress parameters as potential early peripheral biomarkers of effect for monitoring workers with occupational exposure to crystalline silica in a mining ...

Improved survival of leafcutter workers exposed to ...

Improved survival of leafcutter workers exposed to oxidative stress. In the recent paper "Queen loss increases worker survival in leaf-cutting ants under paraquat-induced oxidative stress" published in Philosophical Transaction of the Royal Society B, Megha Majoe, Romain Libbrecht, Susanne Foitzik, and Volker Nehring investigated whether ...
