A manganese oxide-coated cylindrical graphite cathode with a zinc anode was developed to treat wastewater containing selenite in dual-chambered microbial fuel cell. COD and removal the anodic chamber by Bacillus cereus energy generation were evaluated batch mode. dioxide-coated tested for its surface morphology chemical composition using scanning electron microscopy dispersive analysis of X-ray...

Among the substances that attracted the attention of oncologists in recent years are selenium-containing compounds, both inorganic and organic. Several epidemiological studies have shown an inverse correlation between selenium intake and cancer incidence. In the experiments reported here, we compared the effects of 2 inorganic selenium-containing salts that differed in the level of selenium oxi...

background: successful therapy of leishmaniasis depends on effective cellular immune response. we evaluated the effectiveness of sodium selenite and zinc sulphate as known immunomodulator materials, in combination with glucantime® in treatment of cutaneous leishmaniasis lesions resulting from leishmania ma­jor in susceptible animal model. methods: thirty three female mice weighing 18-20 g at th...

Seven-thousand-and-thirty-six specimens of faeces were examined for Salmonellae using three enrichment culture media in parallel.Rappaport's magnesium chloride malachite green broth medium proved superior to selenite F and tetrathionate broths in the recovery of a wide variety of Salmonella serotypes. However, it was inferior to selenite broth in the recovery of Salmonella typhi.A higher recove...

Selenium (Se) was applied to perennial ryegrass (Lolium perenne) and subterranean clover (Trifolium subterranean) pasture as a fertilizer to determine the effect of Se form and concentration on Se accumulation in subsequent forage growth. Treatments were a no Se control, 0.6 kg/ ha Se as sodium selenate, and 0.6, 1.1, and 2.2 kg/ha Se as sodium selenite, all applied to pasture plots with low so...

Involvement of the bacterial thiopurine methyltransferase (bTPMT) in natural selenium methylation by freshwater was investigated. A freshwater environment that had no known selenium contamination but exhibited reproducible emission of dimethyl selenide (DMSe) or dimethyl diselenide (DMDSe) when it was supplemented with an organic form of selenium [(methyl)selenocysteine] or an inorganic form of...

Since high levels of selenium are used as cancer chemopreventive agents in animals and humans, a better understanding of the metabolism of subtoxic levels is desirable. Absorption from rat small intestine using in situ double perfusion, ligated intestinal segments, and brush border membrane vesicles (BBMV) was used to study selenium absorption. A level of 1.2 mM intraluminal selenite was requir...

Background: Portulaca oleracea (PO) plant, omega-3 fatty acids and combination of sodium selenite and vitamin E can limit negative impacts on testicular tissue and function which may be caused by compensating for defective insulin release, enhancing antioxidant status and decreasing in blood glucose levels. Materials and Methods: A total of 96 adult male Sprague Dawley (SD) rats (weighing appro...

A 2 x 3 factorial experiment conducted in three replicates of a randomized complete block design compared the effects of calcium selenite and sodium selenite at three different levels of Se (.3, 5, or 15 ppm) in the diets of growing swine on performance and tissue Se concentrations. Ninety pigs averaging 12.5 kg of BW were given ad libitum access to corn-soybean meal diets fortified with one of...
