chromium hexavalent ion

03/01/1997 - "Understanding this variability in chromium(VI) reactions may help to resolve the conflicting results from in vitro studies that are aimed at deciphering mechanisms of chromium(VI)-induced cancers."
01/01/2015 - "However, recent studies have shown that Cr(III) is not carcinogenic to rodents, whereas mice chronically exposed to high levels of Cr(VI) developed duodenal tumors. "
11/01/2013 - "We systematically searched for studies reporting on occupational Cr(VI) exposure and cancers of the respiratory tract. "
11/01/2012 - "The study has shown that soil contamination in the industrial and residential regions are similarly significant; while the risk assessment proved that based on the pollutants concentration in the soil, metals with the highest cancer risk values (Pb=2.62E-02 and Cr(VI)=1.52E-02) have the potential of affecting the health status of the residents, especially for children in the region. "
01/01/2011 - "Oral ingestion of hexavalent chromium through drinking water and cancer mortality in an industrial area of Greece--an ecological study."

07/01/2012 - "However, restoration of physiological levels of Asc (≈ 1 mM) completely eliminated Cr(VI) hypersensitivity of XRCC1 knockdown. "
05/01/1991 - "Multicenter patch test titration studies in human subjects using an incidence of positive patch tests of 10% or less showed that the threshold for skin hypersensitivity reactions to hexavalent chromium was determined to be of the order 0.001%, equivalent to 10 ppm or 10 mg/kg or 10 mg/L.(ABSTRACT TRUNCATED AT 250 WORDS)"
01/01/2014 - "However, the exact effects of ROS on the signaling molecules and cytotoxicity involved in Cr(VI)-induced hypersensitivity have not yet been fully demonstrated. "
05/01/2006 - "These colourants may contain chromium (VI), which cause skin allergies through percutaneous adsorption on the skin. "
01/01/1995 - "[Early diagnosis and effective prevention of occupational allergies caused by hexavalent chromium]."

06/01/1994 - "The data from these studies were used to assess the risk of developing allergic contact dermatitis due to contact with Cr(VI) and Cr(III) in soil. "
01/01/2003 - "A patient with allergic contact dermatitis caused by hexavalent chromium plating on a cellular phone has already been reported. "
03/01/1999 - "It was concluded that exposure to similar concentrations of Cr(VI) in the environment does not pose an allergic contact dermatitis hazard, even to Cr-sensitized persons."
06/01/1994 - "The findings indicated that soil concentrations at least as high as 450 ppm Cr(VI) and 165,000 ppm Cr(III) should not pose an allergic contact dermatitis hazard for at least 99.99% of the people in the community who might be exposed."
12/01/1993 - "While it has been demonstrated that direct dermal contact with solutions containing Cr(VI) may elicit allergic contact dermatitis (ACD) in previously sensitized individuals, it is unknown to what degree skin moisture may solubilize Cr(VI) from COPR adhering to skin. "

11/01/2003 - "The aim of the study was to determine efficacy of NaQSA in treatment of acute poisoning with a hexavalent chromium compound. "
11/01/2003 - "The results of the study suggest the usefulness of NaQSA in the treatment of poisoning with hexavalent chromium compounds."
01/01/1984 - "Early and repeated high i.v. doses of AA are recommended as the therapy of choice for Cr(VI) poisoning. "
01/01/2014 - "Inhibition of CO poisoning on Pt catalyst coupled with the reduction of toxic hexavalent chromium in a dual-functional fuel cell."
04/01/2009 - "Acute severe chromium poisoning after dermal exposure to hexavalent chromium."

09/01/2001 - "Cr(VI) causes the dissipation of plasma membrane potential and mitochondrial membrane potential in CHL cell cultures, and Cr(VI)-induced ROS may play a role in the injuries."
01/01/2002 - "Sublethal doses of K(2)Cr(2)O(7) did not induce any adaptive stress response, while H(2)O(2) or menadione pretreatment proved protective against the cell injuries caused by Cr(VI). "
01/01/2014 - "Hexavalent chromium (Cr(VI)) overdose causes hepatocellular injuries by inducing mitochondrial damage and subsequent apoptosis in animals and humans. "
