To study the mechanisms and roles of vascular structural changes during the development of hypertension, we coarcted or sham-coarcted the abdominal aorta of rats. At intervals of 3 to 56 days later, we obtained standardized segments of thoracic and abdominal aortas for measurement of dry weight, water content, and amino acid content. Carotid arterial pressure was elevated by day 5 in coarcted r...

In order to evaluate the different growing media and nitrogen fertilizer (urea) on some morphological traits of Spathiphyllum plant, an experiment was carried out in split plot arrangement based on completely randomized design in three replications in greenhouse conditions in 2018. The main plot consisted of different growing media including T1: Leaf-mold, T2: Vermicompost and T3: A mi...

a study was conducted to evaluate the effects of moisture limitation on yield and dry matter distribution between shoot and root of triticale genotypes. this study was performed using a factorial experiment based on completely randomized design with four replications, in agricultural college of ferdowsi university of mashhad greenhouse during 2009. treatments were two available soil water inclu...

the study was conducted to evaluate the effect of different levels of synthetic lysine (slys) on dry matter intake (dmi), average daily weight gain (adg), dry matter conversion ratio (dmcr), carcass characteristics and economics of productionof finisher broiler chicks. as 240 day-old broiler chicks were randomly distributed to 12 pens of 20 chicks each and assigned to four treatment rations in ...

Citrinin is a mycotoxin, which is produced by fungi belonging to the genus Monascus, known in biotechnology as producers of azaphilone pigments. The relation between biosynthesis of these secondary metabolites was investigated in different species of the genus Monascus in batch-culture at the following cultivation conditions: T = 28 degrees C, agitation 220 rpm, and a medium, which induce citri...

in order to study the effects of ph and the ratio of nitrate to ammonium in nutrient solution, on the growth characteristics and on the yield of spinach (spinacia oleracea l.), a factorial experiment was conducted consisting of two factors including: nutrient solution ph in three levels (4.5, 6.5 and 8) and nitrate to ammonium ratio of nutrient solution in five levels (100:0, 75:25, 50:50, 25:7...

to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...

in order to study the effect of folic acid on seed reserves partitioning and early vigor of seedlings of kavir wheat cultivar, an experiment was conducted in a completely randomized design with 0, 12.5, 25, 50, 100 and 200 mm of folic acid. results of this study indicated that dry weight of seeds decreased in a same pattern in all treatments and about 6-8% of total seed was structural section. ...

BACKGROUND Because chronic fluid volume overload is associated with higher mortality, we tested whether blood-volume monitored regulation of ultrafiltration and dialysate conductivity (UCR) and/or regulation of ultrafiltration and temperature (UTR) would facilitate dry weight reduction, in comparison to conventional dialysis (CONV). METHODS We carried out a multicenter, 4-week, randomized con...
