Heavy metal resistance by bacteria is a topic of much importance to the bioremediation of contaminated soils and sediments. We report here the isolation of a highly cadmium-resistant Klebsiella planticola strain, Cd-1, from reducing salt marsh sediments. The strain grows in up to 15 mM CdCl(2) under a wide range of NaCl concentrations and at acidic or neutral pH. In growth medium amended with t...

Clostridium butyricum is a kind of anaerobic bacteria, so de-aeration is extremely important during culture. In this paper, adding sodium thiosulfate and cysteine as well as mixed culture with Saccharomyces cerevisiae were adopted in de-aeration during Clostridium butyricum culture. The experimental results showed that the optimal dosage of sodium thiosulfate was 0.004g/mL, where the biomass of...

UNLABELLED Calciphylaxis is a rare and often fatal condition mostly associated with end-stage renal disease. The pathophysiology remains elusive and treatment options are scarce. We present a rare case of severe calciphylaxis after kidney transplantation in a patient with persistent hyperparathyroidism. CASE DESCRIPTION A 78-year-old man with a history of end-stage renal disease developed ede...

Nitrogen dioxide (NO2) absorption in aqueous sulfite solutions has recently gained more attention to reduce NOx emissions. The NO2 removal efficiency is strongly influenced by the competing reactions of and oxidation. present study investigates role oxidation at neutral pH. effects concentration, thiosulfate, pH, inlet oxygen concentration on efficiency, rates were investigated under well-contr...

PURPOSE Calcium oxalate urolithiasis is one of the most common urinary tract diseases and is of high prevalence. The present study proposes to evaluate the antilithiatic property of hydrogen sulfide and its metabolites like thiosulfate & sulfate in an in vitro model. MATERIALS AND METHODS The antilithiatic activity of sodium hydrogen sulfide (NaSH), sodium thiosulfate (Na(2)S(2)O(3)) and sodi...

Present studies have focused on a novel cyanide antidotal system, on the coencapsulation of a new sulfur donor DTO with rhodanese within sterically stabilized liposomes. The optimal lipid composition for coencapsulation of DTO with rhodanese is the combination of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine, cholesterol, cationic lipid (DOTAP), and 1,2-dipalmitoyl-sn-glycero-3-phosphoethano...

Ahead of Print article withdrawn by publisher. BACKGROUND Calciphylaxis in a nondialysis patient is a rare condition and is characterized by calcific deposition in tissue. We present a case of calciphylaxis in a nondialysis patient who was diagnosed by clinical presentation and skin biopsy and was treated with sodium thiosulfate with improvement of skin lesions. CASE A 43-year-old female wi...

Thiol chemoprotective agents can reduce chemotherapy side effects, but clinical use is limited due to concerns of impaired chemotherapeutic efficacy. We evaluated whether an optimized bone marrow chemoprotection regimen impaired the efficacy of enhanced chemotherapy against rat brain tumors. Nude rats with intracerebral human lung carcinoma xenografts were treated with carboplatin, melphalan, a...

Two new members of the genus Thiomicrospira were isolated from an intertidal mud flat sample with thiosulfate as the electron donor and CO2 as carbon source. On the basis of differences in genotypic and phenotypic characteristics, it is proposed that strain JB-A1T (= DSM 12350T) and strain JB-A2T (= DSM 12351T) are members of two new species, Thiomicrospira kuenenii and Thiomicrospira frisia, r...

Wastewater from tanneries contains high concentrations of organic matter, chromium, nitrogen, and sulfur compounds. In this study, an artificial wetland is is used as the tertiary treatment in a tannery in León Gto., México. It consists of three subplots with an area of about 450 m2. Two subplots were planted with Typha sp. and the third with Scirpus americanus. Geochemical analyses along the f...
