background: the ratio of urine protein to urine osmolality has recently been suggested as an accurate method to determine proteinuria.   objective: we studied the correlation of urine protein to urine osmolality ratio with 24-hr urinary protein excretion.   methods: 150 children aged 0.11–17 years admitted to the department of pediatric nephrology were included in this study. early morning urin...

abstractgiven the importance of the notion of efficiency in the country's economic growth, measuring the efficiency and the technology gap for various industries in order to achieve the best possible resource assignment, following the declared policy goals, is of particular importance for those countries, such as iran, which are now at the early stages of the industrialization process. hen...

to evaluate the effects of supplementation of tomato pomace (tp), canola, soybean and tallow oils on performance, carcass characteristics, and bone parameters of heat stressed broilers, 792 d-old arian broiler were divided to 36 pens. each dietary treatment had 4 replicate with 22 birds each. these factorial experiment (3*3) involved 3 kinds of canola, soybean and tallow oils and 3 levels of 0,...

this paper studies the technical efficiency of 12 branches of saman bank over the period 1387-88, relating it to the composition of staff by sex, the ratio of fixed assets to total assets, the age of the branches and the geographic ranking in development indicators of the city where the branch is located in. data envelopment analysis is used to determine the efficiency of branches. the average ...

A chemical equilibrium model was developed to predict the product composition of a biomass gasification system using highly preheated air and steam. The advantages and limitations of this system were discussed from a thermodynamic viewpoint. The first and second law analyses have been conducted for various preheating temperatures and steam/biomass mass (S/B) ratios. The results demonstrated tha...

OBJECTIVE Two rat bioassay experiments are reported. The first investigated the first limiting amino acid in Acacia colei and the second experiment investigated the effect of S-carboxyethylcysteine (CEC; a compound present in acacia seed) on protein use. METHODS In the first experiment, Wistar rats were fed A. colei seed supplemented with three levels of methionine, cysteine, and tryptophan (...

BACKGROUND Physicochemical characteristics of liposome/DNA complexes influence transfection efficiency and affect each other in a very intricate way. The result of this is discrepancies in conclusions drawn about the individual influence of each one. METHODS Aiming to elucidate the influence of liposome/DNA charge ratio and size on transfection efficiency and on each other, we used liposome/D...
