What's the difference between seleniferous and selenium?
Seleniferous
Definition:
(a.) Containing, or impregnated with, selenium; as, seleniferous pyrites.
Example Sentences:

(4) Historical data from one site (Salt Slough), where trace elements in whole fish have been measured since 1969, indicated that Se concentrations increased more than twofold between 1973 and 1977, but thereafter remained near 3.0 micrograms g-1 (dry weight basis), presumably due to the continuing practice of disposing seleniferous tile drainage water into the most convenient stream channel.
(5) The effects of selenomethionine, which occurs in vegetation, are of particular interest with respect to the health of wild aquatic birds in seleniferous locations.
(6) Chronic selenium poisoning in cattle, sheep and horses may result from the consumption of seleniferous plants over an extended period of time.
(7) Inorganic selenium (Se) salts (selenite and selenate oxyanions) and the organic selenoamino acids (selenomethionine and seleniferous grains) are teratogenic and embryolethal in domestic and wild birds.
(8) Interstitial tissue in the testes of rats fed on seleniferous wheat grains appeared oedematous and widened than that of controls.
(9) Determinations of blood selenium levels of the normal human population in and around the state of South Dakota were made and related to known seleniferous areas.
(10) The nitrotoxin producing Astragali contain concentrations of Te greater than that encountered in nonseleniferous species but less than that in seleniferous ones.
(11) Selenium was measured in red blood cells, serum and hair of children and in breast milk of mothers in seleniferous areas of Venezuela by means of neutron activation analysis.
(12) The differences in the effectiveness of each treatment between the two seleniferous soils may be a result of the residual N content of the sediments.
(13) Studies of marginal safe Se-intake have been carried out in a seleniferous section of China since 1985.
(14) Seleniferous species of Astragalus contain larger quantities of Te than plants in the Ely area, whereas nonseleniferous members of this genus contain much less.
(15) Subchronic effects of selenomethionine, which occurs in vegetation, are of particular interest with respect to the health of wild aquatic birds in seleniferous locations.
Selenium
Definition:
(n.) A nonmetallic element of the sulphur group, and analogous to sulphur in its compounds. It is found in small quantities with sulphur and some sulphur ores, and obtained in the free state as a dark reddish powder or crystalline mass, or as a dark metallic-looking substance. It exhibits under the action of light a remarkable variation in electric conductivity, and is used in certain electric apparatus. Symbol Se. Atomic weight 78.9.
Example Sentences:
(1) It was tested for recovery and separation from other selenium moieties present in urine using both in vivo-labeled rat urine and human urine spiked with unlabeled TMSe.
(2) Dietary factors affect intestinal P450s markedly--iron restriction rapidly decreased intestinal P450 to beneath detectable values; selenium deficiency acted similarly but was less effective; Brussels sprouts increased intestinal AHH activity 9.8-fold, ECOD activity 3.2-fold, and P450 1.9-fold; fried meat and dietary fat significantly increased intestinal EROD activity; a vitamin A-deficient diet increased, and a vitamin A-rich diet decreased intestinal P450 activities; and excess cholesterol in the diet increased intestinal P450 activity.
(3) Mice exhibiting this suppression of immunity had levels of blood glutathione peroxidase, serum selenium, and liver DNA, RNA and protein similar to mice receiving selenium only.
(4) Excess levels of selenium (2.5 and 5 ppm) in the vitamin E-deficient diet had little or no effect on spleen size or hematocrit of rats not receiving lead, but partially prevented the splenomegaly and anemia of red cells from either non-poisoned or lead-oisoned vitamin E-deficient rats, but not as effectively as vitamin E. These results show that vitamin E status of rats is more important that selenium status in determining response to toxic levels of lead.
(5) Plasma selenium concentration and glutathione peroxidase activity in the subjects who died within 1 year of screening were 89% and 88%, respectively, of the values among survivors (p less than 0.01).
(6) Although selenium deficiency in livestock is consequently now rare in Oregon, selenium-deficient soils and attendant selenium deficiency conditions have been reported near the Kesterson Wildlife Refuge in the Northern part of the San Joaquin Valley, California, where, paradoxically, selenium toxicity in wildfowl, nesting near evaporation ponds, occurred and attracted wide attention.
(7) The synthetic "C" nucleoside, tiazofurin (2-beta-D-ribofuranosylthiazole-4-carboxamide), its selenium analogue selenazofurin, and the related inhibitor of inosine 5'-phosphate (IMP) dehydrogenase, mycophenolic acid, are effective inducers of the terminal differentiation of HL-60 promyelocytic leukemia cells.
(8) Thus, in this population with intermediate selenium intake, low serum selenium is not associated with an excess risk of myocardial infarction.
(9) Liver, blood, kidney and lungs were found to contain most of the selenium, here also a two-phased elimination was observed.
(10) These findings suggest that neither serum levels of selenium nor those of retinol have an appreciable effect on the risk of cancer.
(11) The incidences of esophageal tumors were statistically not significant among rats on normal, high and low selenium intake (P greater than 0.05).
(12) Alteration of guinea pig erythrocyte superoxide dismutase activity by the dietary antioxidants ascorbic acid and selenium was investigated.
(13) The more severe was the PIH the lower was the selenium level.
(14) Significantly lower selenium values were observed in blood from colorectal cancer patients than from normal individuals (0.1349 ppm vs. 0.1502 ppm.
(15) Selenium-deficient rats were used to examine the nature of the oxidant stress.
(16) Although treatment with beta-carotene tended to decrease the incidence and number of large intestinal carcinomas, beta-carotene, selenium, esculin and eugenol all decreased the incidence of kidney nephroblastomas, the differences were not statistically significant.
(17) These studies were designed to measure leukotriene B4 (LTB4) production by polymorphonuclear leukocytes (PMN) from selenium (Se)-deficient and Se-adequate goats.
(18) Copper deficiency impairs cell-mediated immunity, as does selenium deficiency when it is associated with vitamin E lack.
(19) Many forms of selenium supplement are commercialized.
(20) The possibility that a sub-clinical deficiency of the trace element selenium might exist in a sample of the British population was examined by giving a selenium supplemented for 5 weeks.
