TL;DR: X-Band EPR studies on aqueous solutions of potassium dichromate and gamma-L-glutamyl- L-cysteinylglycine (reduced glutathione) at pH 6-8 have shown the formation of several relatively long-lived chromium(V) species.

TL;DR: Of all the compounds tested in this work, trimethyltin chloride was, by far, the most toxic and synergistic, and also found to be synergistic was the interactive effect of trimethyeltin chloride with cadmium and chromium applied together.

TL;DR: A convenient and high yield preparation of 4, 4′-dicarboxy-2, 2, 2′-bipyridine from the oxidation with potassium dichromate in sulfuric acid is reported in this paper.

TL;DR: In 12 cases an etiological connection could be traced between the oral symptoms and the denture base, indicating that contact sensitivity to base materials or to allergens and microbial antigens on the dentures plays a greater role in the pathogenesis of BMS in edentulous persons than previously suggested.
Abstract: The significance of sensitizing compounds in the denture base for the etiology of the burning mouth syndrome (HMS) has been studied in 53 denture-wearing persons, seven mules and 46 females. Epicutaneous patch tests were performed with standard concentrations of benzoyl peroxide, dibutylphthalate, dimethyl-p-toluidine, formaldehyde, hydroquinone, methylmethacrylate, p-phenylendiamine and with cadmium sulfate, potassium dichromate, cobalt chloride and nickel sulfate. Furthermore, patch testing was performed with filings from the denture mixed with the patient's own saliva. In cases with an inflamed oral mucosa, the presence of hyphae of Candida albicans was assessed by a smear technique. Positive skin reactions were observed in 15 persons to dimethyl-p-toluidine, hydroquinone, formaldehyde, methylmethacrylate, p-phenylendiamine, potassium dichromate, cobalt chloride and nickel sulfate, including three cases with reactions to filings from their dentures, and one patient, who after subsequent testing showed skin sensitivity to balsam of Peru. In 12 cases an etiological connection could be traced between the oral symptoms and the denture base, indicating that contact sensitivity to base materials or to allergens and microbial antigens on the denture plate plays a greater role in the pathogenesis of BMS in edentulous persons than previously suggested.

TL;DR: All the biochemical contents and enzyme activities of water lettuce and soybean seedlings showed a great variation with respect to the increase in chromium concentrations and total inhibition of all the parameters were observed at 300 mg/L chromium concentration.
