human granulocyte-colony stimulating factor (hg-csf) cdna was expressed in the methylotrophic yeast pichia pastoris under the control of the alcohol oxidase (aox1) promoter. an expression vector for hg-csf secretion was constructed using vector ppic9. higher levels of hg-csf was obtained using a p. pastoris mut+ (methanol utilization fast) phenotype. the effects of environmental factors such as...

Meal-fed rats and rats fed ad libitum had similar rates of hepatic glycogenesis at 60 min after the initiation of re-feeding a chow meal after 22 h starvation, but hepatic PDHa (active form of pyruvate dehydrogenase) activities were 4-fold higher in the meal-fed group. In heart, PDHa activities were 3-fold higher before re-feeding and 2-fold higher after re-feeding in the meal-fed group compare...

this study was conducted to evaluate the effects of different proportions of lemon bee brush essential oil on growth performance, carcass composition, and hematology and biochemical parameters of common carp (cyprinus carpio). common carp with an average weight of 8 ± 0.2 g were fed for one month with a diet supplemented with lemon beebrush essential oil (0.15 and 0.3 ml) and with normal diet a...

This study was conducted to determine optimal ratios of dietary linolenic acid (18:3n-3, LnA) to linoleic acid (18:2n-6, LA) for Tor tambroides. Juveniles were fed three trial diets with different ratios of LnA/LA (0.0, 0.5 and 1.0) for 10 weeks. Another diet contained 100% palm oil, which was similar tothe diet with 0.0 LnA/LA ratio but different in total amounts of C18polyunsaturated fatty ac...

The serum proteinograms of 10 female Holstein calves fed milk either through conventional (COV) or step-down (STP) milk feeding methods at different ages were evaluated. Calves fed using the COV method were fed colostrum during the first 24 hours that they stayed with their respective mothers and received transition milk for another 2 days and later, and then milk at four liters/day for 59 days...

as one of the most promising distributed generation (dg) sources, wind power technology has been widely developed in recent years. doubly fed induction generator (dfig) is currently employed as one of the most common topologies for wind turbine generators (wtgs). this generator operates as a synchronous/asynchronous hybrid generators. therefore, it is necessary to power engineers find understan...

multi-environment trials play a significant role in selecting the best cultivars to be used at different locations. the objective of this study was to identify grain and forage yields stability of grass pea advanced lines across different locations. the 14 advanced lines of grass pea, developed by the international center for agricultural research in dry areas (icarda), were tested at three dif...

the aim of this study was to evaluate the effects of tannic acid (ta) and pistachio by-product tannin extract (pbe) on n utilization and efficiency of microbial nitrogen synthesis (emns) in saanen dairy goats. the experimental design was a change over design with three treatments and three periods using six mid lactation multiparous dairy goats. tannic acid solution and pbe were added to fresh ...

abstract in this study different proportions of nh4+ and no3- in the growth medium on plant growth were investigated in hydroponic greenhouse experiments. the objectives of these studies were to investigate if ammonium (nh4+) stress in cucumber, a species sensitive to nh4+ toxicity, can be alleviated by matching the nitrogen supply rate to the plant nitrogen demand. ammonium was applied at a re...
