purpose: to assess orbital color doppler ultrasonography (cdu) parameters of patients with manifest hyperopia in comparison to the emmetropes methods: forty eyes of 40 patients presenting with manifest hyperopia were included into the study. forty eyes of 40 emmetropes healthy volunteers also were examined as the control group. we have evaluated ophthalmic artery (oa), central retinal artery (c...

objectives: this study focuses on the hematological parameters change and age in radiation field workers. the study aimed to identify the effect of radiation on hematological parameters and their relation to age and duration of the experience in radiation field workers. material and methods: this study was conducted in the physiology research center in collaboration with thalassemia and hemogl...

this study was designed to investigate the effects of different levels of tarragon powder on performance, carcass characteristics of broiler chickens. two hundred ross 308 male broiler chickens were randomly allocated into four treatments and five replicates per treatment. at each replicate ten birds were used. experimental diets were set on the basis of corn-soy-wheat and ross 308 broiler chic...

the purpose of this study was to investigate the hypothesis weather the combination of lead acetate and deltamethrin can enhance avian toxic effects produced by lead exposure only. overall, 48 japanese quails, coturnix coturnix japonica (15 day old) were randomly divided into 4 experimental groups of 12 birds each and sex ratio of 1:1. experimental groups consisted of control japanese quails, b...

Acid-base equilibrium and pH of blood have important clinical consequences in numerous diseases and pathophysiological conditions. The micro-rheological parameters of blood, such as red blood cell deformability and red blood cell aggregation are influenced by several metabolic factors, and provide information regarding inflammatory, septic and tissue or organ ischemia-reperfusion processes. Des...

the replacement of corn silage with varying levels of ammonia gassed wheat straw on performance, digestibility, fermentation parameters, chewing activities, blood metabolites and profitability of holstein heifers have been evaluated. fifteen holstein heifer with 9-10 months of age were assigned in a completely randomized design with 3 treatment as 1) 36% corn silage, 2) 18% corn silage and 18% ...

Objectives. Umbilical cord blood analysis for assessment of the newborn’s acid-base status soon after birth is the most objective way of evaluating the fetal metabolic condition at delivery. We researched the effects of maternal age, multiple gestation, fetal heart rate, gestational age, parity, delivery mode and total duration of labor on fetal well-being as assessed by umbilical cord blood ga...

Objective Argon plasma coagulation (APC) and helium plasma coagulation (HPC) are electrosurgical techniques that provide noncontact monopolar electrothermal haemostasis. Although these techniques have been widely used clinically during the last three decades, their in vivo effects on liver tissue remain unclear. Methods We investigated the effects of different power levels (10-100 W) of APC and...

PURPOSE Current knowledge about pulmonary/systemic hemodynamics and gas exchange during neonatal resuscitation in a model of transitioning fetal circulation with fetal shunts and fluid-filled alveoli is limited. Using a fetal lamb asphyxia model, we sought to determine whether hemodynamic or gas-exchange parameters predicted successful return of spontaneous circulation (ROSC). METHODS The umb...
