OBJECTIVES Growth velocity is an important factor to monitor for appropriate child growth. This study presents the growth velocity of infants based on length, weight, and head circumference. METHODS The subjects of this study were 308 neonates (160 boys and 148 girls) born in West Azerbaijan Province of northwestern Iran who were followed from birth for 4 years. The weights and lengths of the...

We investigated the ability to perceive the metric shape of elliptical cylinders. A large number of previous studies have shown that small perspective variations (< or =10 degrees) afforded by stereovision and by head movements fail to allow accurate perception of metric shape. If space perception is affine (Koenderink & van Doom, 1991), observers are unable to compare or relate lengths in dept...

The lipochromic mosaic canary is a cage bird breed present with different coat colors, red, and yellow, this presents significant sexual dichromatism. Dichromatism in canaries explained by differential carotenoid degradation the integument, rather than sex-specific variation physiological functions such as pigment uptake or transport. Males have an intense color compared to females especially a...

The aims of this study were to identify factors associated with birthweight, birth length and head circumference for triplets, and analyze these body size parameters at birth, especially head circumference, according to gestational age. The subjects of this study were 370 mothers and their 1109 triplet children (excluding one stillborn infant) who were born between 1978 and 2002. The gestationa...

results in the first three years, the team managed the care of 812 admissions. mean age wasn 44.3 years (sd = 24.8) and mean length of hospital stay was 6.1 days (sd = 10.9). ofn these individuals, 674 attended for 6 month follow-up with 52.2% having a good outcomen on extended glasgow outcome score. patients and their relatives' feedbacks weren excellent with an average score of 4.7/5 on overa...

This study describes the morphological, morphometric and ultrastructural characteristics of the Amazonian manatee Trichechus inunguis (Natterer, 1883) spermatozoon. The spermatozoa were obtained from a urine sample of an adult T. inunguis kept in captivity. The spermatozoa were analyzed by light and transmission electron microscopy. The head of Amazonian manatee spermatozoa had a flat oval shap...

　Introduction: Sexual dimorphisms in biological structures such as brain and behaviour have been widely recognized in animals and humans. The purpose of this study was to examine whether there are sex differences in the size of the cerebellum with other body traits, such as the head, tail and brain. Methods: Twelve grasscutters comprising of 6 males and 6 females were used in this study. Each b...

Background: Patient radiation doses from computed tomography (CT) are increasing due to the number of CT examinations performed every day. The aim of this study was assess and evaluate patient radiation doses for adult&rsquo;s common CT examinations to derive local diagnostic guidance levels for common CT examinations. Materials and Methods: Volume and weighted computed tomography dose index (C...
