Comparison of oxidative stress status in the kidney tissue of male rats treated with paraquat and nanoparaquat.

The study aimed to compare the oxidative stress status in the kidney tissue of rats treated with paraquat and nanoparaquat. The levels of oxidative stress markers, including malondialdehyde (MDA), total antioxidant capacity (TAC), and thiol groups (TTG), were measured in the kidney tissue samples. A total of forty male Wistar rats were randomly assigned to eight groups, each consisting of five rats: a control group, a paraquat (PQ) group, an N-acetylcysteine (NAC) group, groups receiving nanoparaquat α and β (α and β), groups receiving PQ and NAC (PQ + NAC), and groups receiving nanoparaquat α and β with NAC (+ NACα and β).

Accessibility of Special Care Dentistry Across Countries: A Scoping Review.

Introduction: People with special care needs often face significant barriers in accessing dental care due to physical and cognitive limitations, leading to high rates of dental issues like caries. Despite the growing recognition of these challenges, unmet dental care needs remain prevalent. This review aims to explore the global landscape of special care dentistry to identify gaps and opportunities for improving dental services for this population.

Computational Design of the Electronic Response for Volatile Organic Compounds Interacting with Doped Graphene Substrates.

Changes in the work function provide a fingerprint to characterize analyte binding in charge transfer-based sensor devices. Hence, a rational sensor design requires a fundamental understanding of the microscopic factors controlling the modification of the work function. In the current investigation, we address the mechanisms behind the work function change (WFC) for the adsorption of four common volatile organic compounds (toluene, ethanol, 2-Furfurylthiol, and guaiacol) on different nitrogen-doped graphene-based 2D materials using density functional theory.

Evaluation of exposure to volatile organic compounds (BTEX) and Polycyclic Aromatic Hydrocarbons (PAHs) in gas station workers and oxidative stress assessment in Karaj city.

Gas stations are one of the sources of benzene, toluene, ethylbenzene and xylene (BTEX) and polyromantic hydrocarbons (PAHs). The present study was conducted with the aim of evaluating the level of breathing exposure of gas station workers to BTEX, PAHs and oxidative stress caused by exposure to these compounds in Karaj city. Oxidative stress and reactive oxygen species (ROS) is one of the mechanisms involved in the toxicity caused by exposure to gas vapors.
