AIM To assess the effects of occupational exposure to carbon disulfide (CS2) concentrations below the threshold limit value (31 mg/m3) on the structural and the functional properties of the arteries, heart rate, blood pressure and lipids. METHODS Study subjects were 85 male workers in the viscose industry and 35 men without such exposure. The CS2 concentration was determined by personal activ...

A CdS/SnS nanocomposite was prepared using a simple hydrothermal method and used as sensitive material for the detection of carbon disulfide (CS2) based on cataluminescence (CTL). The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS) photoelectron spectroscopy (XPS). results show that sensor has high sensitivity to CS...

Female C57BL6 mice were exposed to 0 or 800 ppm carbon disulfide (CS2), 6 h/d, 5 d/wk for 20 weeks. The neurologic function of all mice was assessed once at the end of exposures using a functional observational battery. General health effects included a decrease in body weight gain, piloerection, hunched body posture, and ptosis. Treatment-related effects included altered gait (uncoordinated pl...

Transmission electron microscopic studies on CS2 hydrolase provide direct evidence for the existence of the hexadecameric catenane and octameric ring topologies. Reconstructions of both protein assemblies are in good agreement with crystallographic analyses of the catenane and ring forms of CS2 hydrolase.

Even though atherosclerotic cardiovascular disease (ACVD) is the number one cause of death in the United States, the effects of environmental toxicants on this process are less well studied than the effects of chemicals on the second leading cause of death, cancer. There is considerable epidemiological evidence that workers exposed to carbon disulfide (CS2) have increased rates of ACVD, and the...

In a cross-sectional study, prevalence of dysfunctions of the central nervous system was assessed in 134 male workers exposed to different levels of carbon disulfide (CS2) in a rayon viscose plant and compared to 38 non-exposed workers. In three groups of workers from the same plant with different levels of CS2 (heavy, intermediate, none) estimated by personal samplers, disorders in the central...

Sensory preconditioning (SPC) is a procedure to demonstrate learning to associate between relatively neutral sensory stimuli in the absence of an external reinforcing stimulus, the underlying neural mechanisms of which have remained obscure. We address basic questions about neural processes underlying SPC, including whether neurons that mediate reward or punishment signals in reinforcement lear...
