introduction compartmental analysis allows the mathematical separation of tissues and organs to determine activity concentration in each point of interest. biodistribution studies on humans are costly and complicated, whereas such assessments can be easily performed on rodents. in this study, we aimed to develop a pharmacokinetic model of 153sm-maltolate complex as a novel therapeutic agent and...

this study was undertaken to assess the effectiveness of 5-fu plus epirubicin in the treatment of the advanced gastric cancer. for this purpose, 22 patients with no previous treatment were studied. all of the patients were unoperable or metastatic. follow up checking continued for 24 months. our selected therapeutic regimen consisted of a combination of 500 mg/m2 5-fu dialy for five days, and 7...

mycosphaerella graminicola, the causal agent of septoria tritici blotch (stb), is a widespread and significant pathogen of wheat. to determine mating types, 89 isolates were collected randomly from wheat fields of khuzestan, east azerbaijan, ardebil, kermanshah and golestan provinces of iran, during 2006-7. dna was extracted based on standard protocols. multiplex pcr was conducted using two pai...

the aim of this study was to investigate the hemagglutination properties of caprine herpesvirus-1(cphv-1) and their application for cphv-1 antigen detection and evaluation of the dynamics of postinfectious/vaccine antibody production. cphv-1 hemagglutination activity was proved only with mouseerythrocytes, pbs and saline solutions at 4°c and 22°c. in vaccinated animals, goats and bucks withresp...

this study was conducted to evaluate the responses of two greenhouse tomato cultivars to nutrient solutions' electrical conductivity (ec). two cluster type greenhouse tomato cultivars (razan and ergon) were grown in perlite in a glasshouse hydroponic system. the grown plants were daily fed with either constant ec nutrient solutions (ecs 2, 3 ds m-1) or nutrient solutions of alternatively c...

introduction there are significant differences in the spatial distribution of the iran annual precipitation. this is resulted from spatial behavior of precipitation in the one hand and variation in the sources of precipitation on the other. the lack of adequate distribution of meteorological stations and the unavailability of long-term statistics of precipitation makes the analysis of precipita...
