background- cd24 is a cell adhesion molecule that has been implicated in metastatic tumor progression cells. our aim was clarify correlation between cd24 expression and camp:cgmp ratio in murine colorectal cancer cell line (ct26) after using cholera toxin. materials and methods- the ct26 cells were cultured in microtubes for assaying camp and cgmp; also the cells were cultured in flasks for ass...

assembly lines are special kinds of production systems which are of great importance in the industrial production of high quantity commodities. in many practical manufacturing systems, configuration of assembly lines is fixed and designing a new line may be incurred huge amount of costs and thereby it is not desirable for practitioners. when some changes related to market demand occur, it is wo...

graham higman has defined coset diagrams for psl(2,ℤ). these diagrams are composed of fragments, and the fragments are further composed of two or more circuits. q. mushtaq has proved in 1983 that existence of a certain fragment γ of a coset diagram in a coset diagram is a polynomial f in ℤ[z]. higman has conjectured that, the polynomials related to the fragments are monic and for a fixed degree...

the sporozoites of theileria annulata invade bovine mhc ii cells, where they differentiate into schizonts. the later can immortalize and induce fundamental changes in their host cells. live attenuated vaccine is an important way of controlling t. annulata infection of cattle. production is by prolonged cultivation of macroschizont-infected cells. the mechanisms underlying this transformation ar...

methods s. cerevisiae was cultured and then disrupted by sonication. after centrifugation, the harvested supernatant was considered to be a cytoplasmic extract. the protein concentration was determined by the biuret method and the extract was diluted to concentrations of 500, 1000, and 2000 µg protein/ml. the frequencies of apoptosis and necrosis were assessed in extract-treated k562 cells by e...

the purpose of this reaserch is to measure the phase equilibrium data of the ternary system (water + phosphoric acid + 1-nonanol) at different temperatures. experimental solubility curves and tie-line points for the system were obtained at t = 298.2, 308.2 and 318.2 k and ambient pressure. the binodal curve data were detected by the cloud point method. the mass fractions of each layer were achi...

the aim of this study was to evaluate the effectiveness of individual-focused stress management training namely deep breathing exercise (dbe) on self-perceived occupational stress among male automotive assembly-line workers.a quasi-experimental study was conducted at 2 automotive assembly plants in malaysia over 9 months, from january 2012 to september 2012. assembly-line workers from plant a r...

background: the adjuvanticity potential of lactobacillus casei was first suggested in an old survey. the present study was designed to investigate the efficacy of a new immunotherapy against breast cancer made by mixing an extract of heated 4t1 mammary carcinoma cell line and a heat-killed preparation of lactobacillus casei. methods: female balb/c mice (6–8 weeks old, n=40) were challenged subc...

aim : in this paper effect of combinational usage of calprotectin and etoposide on ags cell line is studied. background : application of combined toxic agents such as etoposide and cicplatin are commonly used for chemotherapy purposes. as a matter of fact, calprotectin and etoposide were both applied on human gastric adenocarcinoma cell line (ags) as antitumor agents. both calprotectin and etop...
