Background: We examine the GA-repeat core promoters of MECOM and GABRA3 in human embryonic kidney-293 cell line and show that those GA-repeats have promoter activity,and those different alleles of the repeats can significantly alter gene expression.We propose a novel role for GA-repeat core promoters to regulate gene expression in the genes involved in development and evolution. Materials and M...
in this research, the effect of micro turbulence on the flotation rate of quartz particles was investigated. the maximum particle reynolds number (rep) was obtained at 60.25 with a particle size of -500+420 µm, impeller speed of 900 rpm, bubble surface area flux of 10.21 1/s and micro scale turbulence size of 162 µm. when the micro turbulence size was equal to the particle size, the maximum flo...
This experiment was conducted to determine the performance and intestinal microflora population of broiler chicks in diets supplemented with Roxarsone, Avilamycin and Formycin gold during starter period. A basal diet was formulated according to NRC (1994) recommendation for starter (0-21 d) period and also supplemented with appropriate amounts of the mentioned growth promoters. Each of the tr...
