The effects of recombinant human erythropoietin (Ep), granulocyte/macrophage (GM) and granulocyte (G) colony-stimulating factors (CSF), and interleukin-3 (IL-3) on erythroid burst and GM colony growth have been studied in fetal bovine serum (FBS)-supplemented and FBS-deprived culture. Sources of progenitor cells were nonadherent or nonadherent T-lymphocyte-depleted marrow or peripheral blood ce...

production of extracellular amylase was demonstrated under conditions of high salinity in aerobically cultivated culture of a newly isolated moderately halophilic gram-positive coccus, designated strain f in basal medium containing peptone from meat, yeast extract, nacl (7% w/v) and starch. biochemical and physiological characterization along with 16s rrna sequence analysis placed f in the genu...

An electrophoretically pure preparation of natural human interleukin-1 (IL-i ) was shown to stimulate in vitro colony formation in human bone marrow cultures. Day 4 myeloid cluster-forming cells (CFC). as well as early (day 7) and late (day 10) granulocyte-macrophage colony-forming units (CFU-GM) were stimulated in a dose-dependent fashion. At optimal concentrations of IL-i . the number of day ...

gm.) per square meter. The nonassimilated material (feces) does not change trophic levels but is available to other primary consumers such as bacteria or detritus feeders. The annual energy flow of the snail population was estimated to be about 290 Calories/M2/year, but during the summer the average standing crop of 700 snails/M2 assimilated only about twice as much as the average population of...

in order to study the effect of deficit irrigation at reproductive growth stages on growth and grain yield of four sunflower cultivars namely: azargol, allstare, alison and euroflor, an experiment was conducted during the 2007 growing season at the experimental field of the agricultural faculty of bu-ali sina university. the experimental design was a split plot one, based upon a randomized comp...

to study the effects of nano-zinc oxide and seed inoculation with brady rhizobium and plant growth promoting rhizobacteria on yield and some agronomic traits of soybean, a factorial experiment based on randomized complete block design with three replications was conducted in 2013 at the research farm of the islamic azad university, ardabil branch. treatments were foliar application of nano-zinc...

pseudomonas aeruginosa is a leading cause of bum infections, and antibiotic- resistant strains of this bacterium are emerging due to extensive application of antibiotics in the bum unit of hospitals. in this study 50 strains of p. aeruginosa were isolated from bum patients infected with this micro-organism in the bum unit of a general hospital in kerman, iran over one year [may 1999-aprii2000]....
