In order to harvest selenium-enriched fruiting body and spores of Ganoderma lingzhi and spent medium, G. lingzhi was cultivated in kudzu vine as substrate and the bio-transformation of selenite was evaluated. The growth medium consisted of Kudzu vine supplemented with 20% wheat bran or sawdust or none. The growth medium was supplemented with 0, 10, 20, 30, and 50 mg/kg of sodium selenite. We found a significant difference in spawn run speed, fruiting body and spore yields when Kudzu vine was supplemented with wheat bran or sawdust. However, when whole-kudzu vine was used alone as substrate, it resulted in a significantly lower spawn run speed, fruiting body, and spore yields compared with kudzu vine + sawdust substrate and kudzu vine + wheat bran substrate. The selenium content in fruiting body and spores increased with increasing sodium selenite supplementation and approximately equaled half of the selenium in the substrate. No selenite was detected in both the fruiting body and spores. However, in the spent medium when sodium selenite was supplemented at 10, 20, 30, 50 mg/kg, the residual selenite concentration decreased to 0.45, 0.72, 1.29, and 1.95 mg/kg, respectively, suggesting a higher selenite transformation (92.27–93.57%). In conclusion, if Ganoderma fruiting body and spores were to be harvested for human consumption, approximately 50 mg/kg selenite should be added to the growth substrate. On the other hand, if the spent medium was to be used as an organic selenium source, the optimal sodium selenite supplementation level would be 10 mg/kg.

ObjectiveTo compare the effectiveness of five kinds of selenium supplementation for the treatment of patients with Kashin-Beck disease, and rank these selenium supplementations based on their performance.DesignWe searched for all publications between 1 January 1966 and 31 March 2017 using seven electronic databases. GRADE system to network meta-analyses (NMAs) was applied to rate the quality of the evidence. We conducted a random effects model NMA in STATA 12.1 to determine comparative effectiveness of each intervention. Rankings were obtained by using the surface under the cumulative ranking curve (SUCRA) values and mean ranks.ResultsA total of 15 randomised controlled trials involving 2931 patients were included. After assessment of the overall quality of the evidence, we downgraded our primary outcomes from high to low or very low quality. NMAs showed that all five kinds of selenium supplementation had higher metaphysis X-ray improvement which were superior to placebo. Ranking on efficacy indicated that selenium salt was ranked the highest, followed by sodium selenite + vitamin E, selenium enriched yeast, sodium selenite and then sodium selenite + vitamin C.ConclusionsBased on the results of NMA, all five types of selenium supplements are more effective than placebo and so that selenium supplementation is of help in repairing metaphyseal lesions. Since the overall quality of the evidence was low or very low, the SUCRA values may be misleading and should be considered jointly with the The Grading of Recommendations Assessment, Development and Evaluation (GRADE) confidence in the estimates for each comparison. The quality of the evidence is insufficient to draw a conclusion about what method of selenium supplementation is most effective.PROSPERO registration numberCRD42016051874.

This investigation evaluated, in broiler chickensPectoralisandGastrocnemiusmuscles, the effect of the dietary supplementation with sodium selenite (0.3 ppm) versus selenomethionine (0.3 ppm), on the fatty acids composition, lipids indices, and enzymes indexes for desaturase, elongase, and thioesterase. The selenium reduced, in both muscles, the content of atherogenic fatty acids, C14:0 and C16:0, while it increased the C18:1 level. On the other hand, selenium increased, in both muscles, the content of C18:3n3 and EPA, but not DPA and DHA. No selenium effect was detected for PUFA/SFA, n-6, n-3, n-6/n-3, and atherogenic and thrombogenic indices. As for the enzyme indexes, a selenium effect is only detected for thioesterase. Taken together, the results highlight the potential effect of dietary selenium, mainly selenomethionine, in the modulation of the composition of fatty acids in chicken meat, in particular, reducing the content of atherogenic fatty acids and increasing the health promoting n-3 PUFA.

This work studied the effect of dairy cow ration supplementation with inorganic plus organic Se on metabolic status, milk yield, and the quality of milk and dairy products, especially its Se content. Twenty multiparous Holstein Friesian lactating cows were assigned to two feeding treatments. The cows were fed with 22.5 kg dry matter (DM) of total mixed ration (11.75 kg DM of forage plus 10.75 kg DM of concentrate) by head. There were two different concentrates with the same Se content (0.240 mg/kg of ration DM) but with different Se sources: The control (CON) was supplemented with inorganic Se (sodium selenite); and the other (IOSe) was supplemented with sodium selenite plus organic Se (Sel-Plex®), at 0.144 and 0.096 mg Se/kg of ration DM, respectively. The results indicated that, in general, the IOSe treatment did not modify the metabolic profile, and even decreased the total oxidant status (p < 0.05) and did not lead to a deterioration of quality and yield of milk. However, milk and cheese from IOSe had higher Se content (an increase of 29.7% and 38.2%, respectively) than CON (p < 0.01), but this effect was not observed in yogurt. In general, physical or sensorial parameters of cheeses did not show differences between treatments. Moderate inorganic plus organic Se supplementation may be more effective than inorganic Se, increasing the Se content in milk and cheese, without causing a deterioration in quality or productive parameters.

Two hundred-forty 3-weeks-old Aseel birds from Lakha, Mushki, Peshaweri and Mianwali varieties of indigenous Aseel were chosen (60 birds/variety, 30 males and 30 females) to evaluate the influence of selenium supplements on growth performance. The birds of either sex were divided according to randomized complete block design into A, B and C treatment groups (10 birds/treatment); A and B were experimental, while C was control. Se-enriched yeast (organic selenium) and sodium selenite (inorganic selenium) were supplemented @ 0.3 mg/kg in the basal diets of group A and B, respectively, while, group C was fed without additional selenium. Birds were maintained individually in battery cages from 4-21 weeks. Statistically, the results showed the reduced (P>0.05) feed intake, while enhanced (P£0.05) nutrient utilization for dry matter, crude protein, crude fiber, crude fat and ash; superior feed conversion ratio; higher live final body weight; lower (P£0.05) mortality and rearing cost in Se-enriched yeast fed birds, chiefly in the males of Lakha variety than those received sodium selenite supplemented or control diet. The study concluded that the organic selenium supplement (Se-enriched yeast) had a major influence in improving the overall growth performance of Aseel.

<p>This study was conducted to determine the effects of inorganic selenium (sodium selenite) and organic selenium (selenomethionine) supplementation on growth and viability of juvenile humpback grouper (Cromileptes altivelis). The experiment was designed as a completely randomized design with eight treatments and three replications. The treatment being tested was source and dosages of selenium ie., inorganic selenium (sodium selenite) supplementation with dosages of 0.5, 1, 2, and 4 mg Se/kg diet and organic selenium (selenomethionine) with dosages of 1, 2, and 4 mg Se/kg diet. Another treatment was unsupplemented selenium. Juveniles humpback grouper at an initial average length of 6,39±0,41 cm and body weight of 4,49±0,65 g were reared in 90×40×35 cm3 aquaria and fed artificial diet (pellet) two times daily (08.00 and 16.00) at satiation. Fishes were reared for 40 days at a stocking density of 12 fish per aquarium on sea water with salinity of 30–31 ppt and temperature of 28–29 °C. The results of this study showed that the source of selenium supplementation (inorganic or organic) affected growth performance, glutathione peroxidase (GPx) enzyme activity, and blood profiles of the experimental fish. Generally, it was found that selenomethionine supplementation resulted in better fish performance than sodium selenite. In sodium selenite supplementation, survival declined with the increased dosages of Se in the diet, and the supplementation at dosage of 0,5 mg Se/kg diet showed a toxic effects. Histopatological test showed that there were damage in livers, kidneys, and intestines of fish supplemented with sodium selenite from 0.5 to 4 mg Se/kg diet. On the contrary, supplementation of selenomethionine up to 4 mg Se/kg did not show any signs of toxicity and the survival was on 86.11 to 97.22%. Feed efficiency, protein retention, lipid retention, and Se retention indicated that a dosage of 4 mg Se/kg selenomethionine supplementation was the best dosage.</p><p>Keywords: selenium, viability, growth, Cromileptes altivelis, humpback grouper</p>

A 4-week experiment was carried out on 360 laying hens of the Hy Line Brown hybrid. Laying hens were divided into three groups (C, E1 and E2) with 120 hens in each group and kept in 24 cages. Hens were fed layer diets containing 18% of crude protein and 11.60 MJ ME. Hens in the control group C were fed diets that contained 0.2 mg/kg of inorganic selenium (sodium selenite). Experimental groups E1 and E2 were given diets with increased concentrations of selenium as follows: E1 = 0.4 mg/kg of selenium (sodium selenite), E2 = 0.4 mg/kg of organic selenium (Sel-Plex). Selenium concentration in diets affected significantly the content of selenium in albumen (P < 0.001) and yolk (P < 0.05). The highest concentration of selenium was determined in albumen and yolk of eggs produced in group E2 (345 ng/g and 783 ng/g, respectively), then in eggs of group E1 (230 ng/g and 757 ng/g, respectively), and group C had the lowest concentration of selenium in albumen and yolk (181 ng/g and 573 ng/g, respectively). After 28 days of storage at 4 °C, the eggs containing organic selenium had more freshness (VN: C = 32.9, E1 = 2.60, E2 = 2.11). It was concluded that higher concentration of organic selenium in eggs was a limiting factor in metabolic processes, which positively affected the indicators of egg freshness.

The objective of this study was to synthesize a new organic selenium compound, carboxymethyl chitosan-selenium (CMCTS-Se), and evaluate its antioxidant abilities on hydroxyl radicals and superoxide radicals. Sodium selenite and carboxymethyl chitosan (CMCTS) were used to prepare CMCTS-Se. It was characterized by ultraviolet (UV) and infrared (IR) techniques. The results proved the successful synthesis of CMCTS-Se. The yield was 44.78% and the content of selenium (Se) was 20.50mg/g determined by colorimetry at 420nm using 3.3-diaminobenzidine as color-produced reagent. The antioxidant activities on hydroxyl radicals and super oxide radicals of CMCTS-Se were investigated. The results showed that antioxidant activities were concentration related in the setting concentration range and the antioxidant effects of CMCTS-Se were totally better than that of CMCTS. The scavenging rates on hydroxyl radicals and superoxide radicals of 2.0mg/mL CMCTS-Se were 68.25% and 62.15%, respectively. VC, a well-known antioxidant, as a standard in our assay, showed a little higher antioxidant activity than CMCTS-Se. This research provides a possible application of CMCTS-Se as a low toxic and effective organic Se-enriched healthy product.
