This paper assesses empirically the relationship between GDP per capita growth uctuations and the age structure and intensity of human capital across developed and developing countries We estimate a spatial vector autoregressive model of income dynamics where the economic distance between countries is de ned on their similarity in measures of human capital and its distribu tion across age group...
this study presents data on age structure, sex ratio, growth, length-weight relationships and condition factor of four populations (n=312) of two alburnoides species, collected in 2005 and 2006 from the tajan river (caspian sea basin), the ghara-chai and jajrud rivers (namak lake basin), and cheshmeh-ali spring (kavir basin) of iran. sex ratio of the fish, in the studied localities, except in ...
background : insulin-like growth factor-1 can act in both an autocrine and paracrine manner to promote normal growth and malignant cellular proliferation. the importance of this factor as a major regulatory peptide has been established for cells, in vitro and in vivo. however, the role of serum insulin-like growth factor-1 levels in the etiology of benign prostatic hyperplasia and prostate canc...
one of the major goals of antenatal care is estimation of gestational age.the most widely used parameters for evaluation of fetal growth are biparietal diameter (BPD),femoral length (FL) and adbominal circumference (AC).to determine the value of prenatal ultrasonographic scapula measurements for fetal growth and gesattional age a prospective ultrasonographic cross-sectional study was conducted ...
the present study was designed to examine the anatomical parameters of the cardiopulmonary system, the function of venous blood gas parameters and the development of ascites incidence in two genetic line chickens. three hundred forty day-old chickens from two pure broiler breeder lines, which were different in their growth rate and susceptibility to ascites syndrome were obtained. the relative ...
Introduction: Genetic and health factors along with ethnicity and geographic location are factors that affect the time of puberty onset. The aim of the present study was to evaluate the mean age of onset of puberty and its stages in boys of Yazd.

Background and Objectives: Using the anthropometric indicators of children is one of the ways of monitoring their growth. Because of the racial divisions and levels of health and welfare, comparing these indicators with the global reference is not reasonable; therefore, designing a local reference seems necessary. This study aimed to evaluate the growth indices for boys and girls aged 5 to 18 y...
Background and Objective: Growth is an important marker of child health. It has been shown recently that a chronic inflammatory condition, known as Environmental Enteric Dysfunction might play a more significant role on growth velocity than clinical infections. The present study aims to investigate the fecal myeloperoxidase concentration (a marker of gut inflammation) and its relationship with ...
background: exact determination between children's sleep habits and their growth could help us to prevent this risk factor of children's growth disorders. thus this research was performed to investigate the correlation between sleep habits and growth of preschool children in ahvaz- iran. materials and methods: in this cross-sectional study, the data was obtained by using available sam...
a study was conducted to evaluate effects of age at weaning on various growth characteristics and stress measures of zandi lambs. the lambs were weaned at 45 and 90 days of age. the body weights and average daily gain (adg) were monitored during the experimental period and 5 months of age. cortisol, glucose, blood urea nitrogen (bun) and lamb behavior (agitation, vocalization) were recorded bef...
