چکیده
This study was undertaken to investigate the relationships between stage of embryonic development and early posthatch growth and the level of rhodanese (thiosulfate:cyanide sulfurtransferase) activity in different regions of the digestive tract and liver of chickens. The embryos were studied at 14, 17, and 20 d and chickens were 1, 2, and 3 wk old. All tissues studied contained rhodanese. The highest specific activity of rhodanese was present in the liver followed by the proventriculus (P < 0.05). The lowest level was in the esophagus. The level of rhodanese was found to increase with age in the proventriculus and duodenum. The highest rhodanese activity in 3-wk-old chickens was in the proventriculus followed by the liver. These results are discussed in terms of the role of different sections of the digestive tract of the chicken in cyanide metabolism. (

متن کاملSeed priming with Electromagnetic Field Improved Growth, Nutrition, And Metabolism of Salvia nemorosa L.
In this study, the efficiencies of seed priming with electromagnetic field (0, 2, 4, and 6 mT; 30 minutes daily for 3 days) were investigated in Salvia nemorosa. The exposure to electromagnetic filed led to significant increases in biomass accumulation (mean=53.6 %). Electromagnetic filed treatments significantly increased K, Ca, Mg, and Fe contents in leaves by mean 39.5 %. The electromagnetic...

According to the World Health Organization, viable probiotics could have health effects. However, in recent years, many benefits have been observed through application of inactive and non-viable cells of microbes or their metabolites. Therefore, probiotics could be defined as viable, inactive, or non-viable microbial cells or cell extracts that have beneficial health effects on the host. Based...
