Background and Aims: n-hexane is widely used in the production of glues, lacquers, paints, plastic, and rubber products. Therefore, a significant potential for exposure to this toxic solvent exists in industrial settings. This study was carried out to assess the exposure to n-hexane and to determine the correlation between this exposure and urinary concentration of free 2,5-hexanedione (2,5-H...
introduction: the purpose of this study was to compare the push-out bond strength of white proroot mineral trioxide aggregate (mta), biodentine, calcium-enriched mixture (cem) cement and endosequence root repair material (errm) putty after exposure to blood. methods and materials: a total of 96 root dentin slices with a standardized thickness of 1.00±0.05 mm and standardized canal spaces were r...
Introduction: One of the pollutants that is developing in human life day by day is Magnetic field. In modern urban transport systems, diesel motors have been replaced with electric motors, working with alternating and direct currents, and leading to occupational exposure of drivers with magnetic fields. This study aimed to determine the urban train's drivers exposure with static magnetic fields...
Background: Pesticide toxicity is one of the major environmental health problems for the modern societies, as some of the effects may last long time after exposure. Propoxur is one of the Carbamate pesticide largely used in agriculture in the Western region of Cameroon. Methods: In order to evaluate the post-exposure effects of propoxur, 48 male rats (12 animals per group) aged 30 d were orall...
