Background: There is increasing interest about the relationship between metabolism, obesity and function of thyroid hormones in recent decades. This study aimed to determine the validity of a “thyroid and metabolism questionnaire” and its relationship with metabolism status and function of thyroid hormones. Methods: It was a descriptive cross-sectional study on 164 people aged 20-64 years who ...
description of lactation curve were investigated using sine function, compare it with two functions (dijekstra and wood). the data contained 32233 dairy milk yield records from 93 first parity iranian holstein cows that had calving between aug. 2008 and jul. 2009. actual milk production per day and subsequently the actual production of each animal were available in the first lactation. lactatio...
Indirect effects propagated through intervening species in a food web have important effects on community properties. Traditionally, these indirect effects have been conceptualized as mediated through density changes of the intervening species, but it is becoming increasingly apparent that those mediated through trait (phenotypic) responses also can be very important. Because density- and trait...
Background Determinants of health or health production function in health economics literature constitute noticeable issues in health promotion. This study aimed at estimating a health production function for East Mediterranean Region (EMR) based on the Grossman theoretical model. Methods This ecological study was performed using the econometric methods. The panel data model was used in order...
The use of pointers presents serious problems for software productivity tools for software understanding, restructuring, and testing. Pointers enable indirect memory accesses through pointer dereferences, as well as indirect procedure calls (e.g., through function pointers in C). Such indirect accesses and calls can be disambiguated with pointer analysis. In this paper we evaluate the precision...
Chronic antibody-mediated rejection, a common cause of renal transplant failure, has a variable clinical phenotype. Understanding why some with chronic antibody-mediated rejection progress slowly may help develop more effective therapies. B lymphocytes act as antigen-presenting cells for in vitro indirect antidonor interferon-γ production in chronic antibody-mediated rejection, but many patient...
The approximately 100 million tonne per year increase in the use of corn to produce ethanol in the U.S. over the past 10 years, and projections of greater future use, have raised concerns that reduced exports of corn (and other agricultural products) and higher commodity prices would lead to land-use changes and, consequently, negative environmental impacts in other countries. The concerns have...
Morphological traits genetically correlated with wood production have been targeted as an alternative to the indirect selection of Poplar trees for high biomass production. So in this study two Populus species (P. nigra and P. alba) growing in Kermanshah, Zanjan and Esfahan provinces were selected to investigate the relationship between various leaf morphological traits and growth character...
