background: glioblastoma is the most common and most malignant cancer of central nervous system. targeted radiotherapy is an effective method toward its treatment. iododeoxyuridine (iudr) is a halogenated thymidine analogue known to be effective as a radiosensitizer in human cancer therapy. in this study we have evaluated the combination effects of 2-methoxyestradiol, an inhibitor of hypoxia in...

in this study, a simple and low-cost method was developed for extraction and pre-concentration of brilliant blue(bb) and tropaeolin o(to) in food samples using cloud point extraction (cpe) prior to spectrophotometric determination. the effects of main factors such as ph, surfactant and salt concentrations, incubation time and temperature on the cloud point extraction of both dyes were investiga...

this study presents an empirical relationship of suspended sediment concentrations (sscs) inthe coastal waters, which is derived from the conventional methods, to radiometer remote sensing reflectance values (rrs) and satellite data in coastal waters of kerala. an algorithm is then developed to utilize both in situ sscs measured from conventional methods and rrs values. this algorithm is valida...

in this article a comparative study for modeling and optimization of 2-methylpropane-2-thiol removal from contaminated soil by ultrasound is investigated. central composite design (ccd) and artificial neural network (ann) were utilized and compared to each other in order to obtain appropriate predicting model with respect to sonication power (w), sonication time (min) and water/reactor volume r...

the aim of this research was to survey of using soy protein isolates and tragacanth gum as egg substitutes in mayonnaise formulation. the mayonnaise prepared with difierent compositions of soy protein isolate, egg, and tragacanth by applying the optimal mixture design method and effect of this substitution on its stability, heat stability, viscosity, texture, physicochemical and sensory charact...

purpose lipocalin-2 (lcn2), a newer adipocyte-secreted acute phase protein, was recently reported to be correlated with potential effects on obesity and inflammation. the reaction of this protein to progressive exercise has not been evaluated yet. this study was designed to compare the serum lcn2 and high-sensitivity c-reactive protein (hs-crp) levels after participating in an acute bout of tre...

in order to evaluate the effects of organic fertilizer complements application (aminol forte, fosnutren and kadostim) on grain yield, milling properties and nitrogen use efficiency of two rice (oryza sativa l.) cultivars, a field experiment in factorial layout and a randomized complete block design with 10 treatments and 3 replications was conducted at rice research institute of iran in 2009. t...

a simple and rapid microextraction procedure based on dispersive liquid-liquid microextraction (dllme) coupled with gas chromatography-flame ionization detection (gc-fid) was developed for the extraction and analysis of 2-phenylethanol in rose water sample. in the proposed approach, carbon tetrachloride and ethanol were used as extraction and dispersive solvents, respectively. some important pa...

autosomal polycystic kidney disease (adpkd) is a genetic disorder with two causal pkd-1 and pkd-2. genetic studies have demonstrated an important allelic variability between patients but few data are known about genetic variants in african populations. we report a new mutation found in a 41-year old women with mild chronic kidney disease secondary to adpkd. molecular genetic testing found a del...

in order to comparison the foliar application of biological, biostimulator and chemical fertilizers on growth characteristics and yield of saffron, a factorial experiment was conducted in a completely randomized block design with four replication in 3- year field of saffron in dargaz, khorasan razavi province from 2010 to 2011. the first factor had 5 levels included biostimulator fertilizer bio...
