The concentration of plasma free fatty acids in rats was significantly increased after a short period of exposure to inhalation of carbon disulphide (4 h, 2 mg/1). In contrast, after a longer period of exposure (15 h overnight, 2 mg/1) the concentration of plasma free fatty acid was significantly decreased despite a small hypoglycaemia. At the same time plasma urea concentration was significant...
Herein, dithiocarbamate-modified biochar (BC-HDTC) was successfully synthesized with nitric acid (HNO3), thionyl chloride (SOCl2), branched PEI and carbon disulfide (CS2). The effective anchoring of amine dithiocarbamate groups onto the surface proven by SEM, FTIR, XPS, N2 adsorption–desorption experiment. batch experiments demonstrated BC-HDTC can selectively remove 98% Pb(II) within multi-met...
Commercial activated carbon of coconut shell (CS) was used as the raw material for synthesis graphene like using modified Hummers method. The structure CS is amorphous and contains natural minerals such silica, potassium, magnesium calcium impurities. Prior to use, we carried out a thermal pre-treatment process (heating) on in order remove Pieces were grounded size 200 mesh (CS1), then heated a...
The September 1998 issue of EHP contained two articles about the neurotoxicity of carbon disulfide. The "NIEHS News" article (1) reported on a collaborative study that involved scientists from the NIEHS (Nashville, TN). In this study, the neurotoxicity of carbon disulfide was detailed from the earliest molecular alterations to neurobehavioral findings to electrophysiologic and morphologic chang...
IN AN EARLIER STUDY (Barr et al., 1981) we explored the pathogenesis of soft-tissue necrosis induced in guinea-pigs by the concrolled extravascular administration of cytotoxic drugs. This system provides a model of the phenomenon which may complicate the inadvertent perivenous injection of cancer chemotherapeutic agents in clinical practice. The current investigation was undertaken in order to ...
AIMS A six year prospective cohort study was conducted to clarify whether the current carbon disulphide (CS2) exposure level is low enough to prevent subclinical health impairment and/or to ameliorate health effects due to previous high exposure. This paper describes the effects on the cardiovascular systems. METHODS The study subjects were 432 male workers exposed to CS2 and 402 non-exposed ...
The regioselective ring opening of styrene oxide using elemental iodine and bromine in the presence of disulfides as new catalysts was studied. The conductivity titration and UV spectroscopy were used to study the interaction of iodine with these catalysts. The results indicate that disulfide 11 is efficient in polyiodide formation, and can catalyze this reaction in excellent yield and high reg...
In a prospective cohort study, men of Japanese ancestry were clinically examined from 1965 to 1968. For 7,833 of these men, data on black tea consumption habits were recorded. Since 1965, newly diagnosed cancer incidence cases have been identified: 152 colon, 151 lung, 149 prostate, 136 stomach, 76 rectum, 57 bladder, 30 pancreas, 25 liver, 12 kidney and 163 at other (miscellaneous) sites. Comp...
In the group of 37 patients with chronic carbon disulphide (CS2) intoxication manifested by encephalopathy, polyneuropathy or psycho-organic syndrome and complaining for vertigo, a statokinesiometric test was performed with open and closed eyes, and with visual stimulation. Basic test parameters of stabilograms and statokinesiograms were compared with standard values of the control group. Resul...
BACKGROUND The gaseous headspace above naïve Escherichia Coli (E. coli) cultures and whole human blood inoculated with E. coli were collected and analyzed for the presence of trace gases that may have the potential to be used as novel, non-invasive markers of infectious disease. METHODS The naïve E. coli culture, LB broth, and human whole blood or E. coli inoculated whole blood were incubated...
