background: pregnancy and accelerated fetal growth always are related with major metabolic changes and body fat redistribution and adiponectin is one of principle adipocyte hormones, so studying adiponectin changes during pregnancy may reveal some hidden parts of fetal metabolism. the aim of this study was to assess adiponectin and leptin levels in umbili cal cord and maternal serum, their rela...

abstract growth quality index (qgi) is affected by two sets of structural and social composite indicators. structural indicator contributes to achieve the main target of sound, sustainable, and competitive output growth. by the way, the sound output growth should enhance social public services and living standard. although qgis are computed based on different scenarios, the trend of the qgis an...

prematurity and poor weight gaining are important causes for neonatal hospitalization. the present study aimed to investigate the role of medium-chain triglyceride (mct) oil via massage therapy as a supplementary nutritional method on the weight gain of neonatal intensive care units (nicu)-hospitalized neonates. this randomized clinical trial performed among 121 stable premature neonates hospit...

pistachio is the most important nut that is produced in iran. little research has been done to examine the effect of ucb1-hybride rootstock plants as tissue culture for pistachios (2011 in toba company).this study aims to evaluate three pistachio varieties on ucb1 hybrid rootstock.  the experiment was conducted as a randomized complete block design with three treatment groups (including ohadi, ...

five treatments including conway medium, media containing 0.1, 0.17, 0.3 and 0.5 mg l-1 ferrous (fe; in the first experiment), media with 1, 1.26, 1.59, 2 mg l-1 concentrations of phosphorous (p; in the second experiment) and a pure sample of tetraselmis suecica were cultured under laboratory conditions. growth rate of the algae was determined using the optical density method at 750 nm and numb...

the present study was aimed to improve the reproductive performance of corriedale ewes by nutritional flushing. forty corriedale ewes were divided into four treatment groups (tc, t1, t2 and t3) with 10 ewes in each group (n=10). at the beginning of the breeding season extra feeding (flushing regime) was started for approximately 34 days such that two estrus cycles were covered. first group i.e....
