| impaired ketone body metabolism in the selenium deficient rat. possible implications. | male rats were fed a selenium-deficient torula yeast diet with or without 0.2 ppm selenium (as sodium selenite) in the drinking water. selenium deficiency caused a significant increase of urinary acetoacetate excretion in fed rats, and 24 or 48 hours of starvation enhanced this effect. two days of selenium supplementation decreased the amount of urinary acetoacetate and 3-hydroxybutyrate to 50% of the deficiency value, indicating an enzymatic impairment in the selenium-deficient rat. no selenium ... | 1985 | 4058313 |
| differential effects of dietary selenium on hepatic and renal glutathione metabolism in the rat. | studies were undertaken to determine whether or not dietary selenium (se), as sodium selenite, at suboptimal (unsupplemented torula yeast diets, 0.02 ppm se) or supplemented up to dietary excess, but nontoxic, levels (5.0 ppm se) could selectively modify hepatic and renal reduced glutathione (gsh) levels and the enzymes involved in gsh metabolism. male rats were provided torula yeast semipurified diets containing approximately 0.02 ppm se in the basal diet and supplements of 0.1, 2.0, or 5.0 ppm ... | 1985 | 4064933 |

| structure of the 5-s ribosomal rna gene and its adjacent regions in torulopsis utilis. | a dna segment spanning one repeating unit of ribosomal rna(rrna) genes in a yeast strain, torulopsis utilis, has been cloned on a bacterial plasmid pbr322. the size of the cloned segment was about mr = 8.0 x 10(6). all of the genes for the four species of rrna were linked on it, and there was a long spacer between the 5-s and 18-s rrna coding regions. the nucleotide sequences of the regions flanking the 5-s rrna gene were determined and compared with those in the corresponding regions of sacharo ... | 1980 | 6254757 |
| nucleotide sequences of the 5s ribosomal rna genes and their adjacent regions in schizosaccharomyces pombe. | the organization of 5s ribosomal rna (rrna) genes in the genome of schizosaccharomyces pombe has been investigated by restriction and hybridization analyses. the 5s rrna genes were not linked to the other three species of rrna genes which formed a repeating unit of 6.9 megadaltons, but located in other regions surrounded by heterogeneous sequences. the 5s rrna gene organization in s. pombe is therefore different from those in other yeasts; saccharomyces cerevisiae and torulopsis utilis. four res ... | 1981 | 6275361 |
| bioavailability to rats of selenium in various tuna and wheat products. | bioavailability of selenium (se) in tuna and wheat at various stages of processing was studied in rats. the protein source of the rat diets was torula yeast with se supplied by either raw, precooked or canned tuna, or whole wheat flour, whole wheat bread or bran. sodium selenite was used as the standard. each se source was fed at three levels: 0.05, 0.10 and 0.15 ppm. by using increase in glutathione peroxidase (gsh-px) activity in liver, kidney and whole blood as an indicator of bioavailability ... | 1983 | 6296340 |
| responses in calcium and phosphorus metabolism and hepatic lipid deposition among estrogenized chicks fed various dietary ingredients. | the purpose of this study was to determine whether diet composition would influence calcium and phosphorus metabolism in chicks administered estrogen. at 1 day of age, broiler chicks were fed either a corn-soybean meal diet (cs), or an isoenergetic and isonitrogenous diet containing 5% fish meal, 5% alfalfa meal and 10% torula yeast (fay). at 21 days equivalent numbers were implanted with one of two lengths of silastic tubing containing estradiol dipropionate, while the remaining birds served as ... | 1984 | 6699740 |

| roles of selenium and sulfur-containing amino acids in protection against oxygen toxicity. | tolerance and adaptation to hyperoxia have been correlated with increases in antioxidant enzymes. this study evaluated whether selenium deficiency would prevent an increase in glutathione peroxidase (gshpx), a selenium-containing enzyme, during oxygen exposure, and, thus, inhibit adaptation. because the torula yeast-based diet, which was used to produce selenium deficiency, was also deficient in cysteine and methionine, the effects of these deficiencies were also evaluated. when rats were expose ... | 1983 | 6876743 |
| toxic effects of dietary selenium in the syrian hamster. | selenium (se) toxicity and utilization was evaluated in hamsters fed casein- and torula yeast-based diets. 4-week-old hamsters received semipurified diets for 21 days. in experiment i diets were supplemented with either 0.25, 10, 20, 40 or 80 ppm se as sodium selenite (ss) and in experiment ii diets were supplemented with 0.1, 5.0 or 10.0 ppm as ss or selenomethionine (sm). blood and tissue se concentrations and glutathione peroxidase (gsh-px) activity were measured at the termination of the fee ... | 1983 | 6881915 |

| selenium regulates gene expression for estrogen sulfotransferase and alpha 2u-globulin in rat liver. | dietary intake of the essential trace element selenium (se) regulates expression of genes for selenoproteins and certain non-se-containing proteins. however, these proteins do not account for all of se's biological effects. the objective of this work was to identify additional genes whose expression is regulated by se. identification of these genes may reveal new functions for se or define mechanisms for its biological effects. weanling male sprague-dawley rats were fed a torula yeast-based se-d ... | 1998 | 9618024 |
| knockout of cellular glutathione peroxidase affects selenium-dependent parameters similarly in mice fed adequate and excessive dietary selenium. | this study was to determine whether or not effects of the cellular glutathione peroxidase (gpx1) knockout on several se-dependent parameters in mice were tissue, dietary se concentration, and selenoprotein specific. a 2 x 3 factorial experiment was conducted with 18 gpx1 knockout mice [gpx1(-)] and 18 controls (3 weeks old, half males and females). these mice were fed a torula yeast diet supplemented with all-rac-alpha-tocopheryl acetate (50 mg/kg of feed) and se (sodium selenite) at 0, 0.5, or ... | 1998 | 9666319 |

| bioavailability of selenium from raw and cooked ground beef assessed in selenium-deficient fischer rats. | the literature on the bioavailability of selenium (se) from meats, especially beef, is meager, and that which existed when this research began suggested that se was not highly bioavailable. in addition, much of the analytical values for se in beef predated the food and drug administration's 1973 approval of se as an additive to feeds and mineral premixes of livestock. | 1994 | 8157862 |

| dietary selenium and arsenic affect dna methylation in vitro in caco-2 cells and in vivo in rat liver and colon. | selenium is an essential trace element for human health, and it has received considerable attention for its possible role as an anticarcinogenic agent. the purpose of the present study was to determine whether changes in the amount and the chemical form of selenium would affect dna methylation and whether this effect would be modified by arsenic. caco-2 cells, a human colon cancer cell line, were exposed to 0, 1 or 2 micromol supplemental selenite/l and 0, 1 or 2 micromol supplemental arsenite/l ... | 2000 | 11110844 |
| promotion of lipid oxidation by selenate and selenite and indicators of lipid peroxidation in the rat. | the ain-93 reformulation of the ain-76a rodent diet includes a change in selenium supplement from sodium selenite to sodium selenate to reduce dietary lipid peroxidation. a change to selenate as the standard form of se in rat diets would render results from previous work using selenite less relevant for comparison with studies using the ain-93 formulation. to critically examine the rationale for the ain-93 recommendation, we prepared torula yeast basal diets patterned as closely as possible afte ... | 2001 | 11354350 |
