AIM Cardiopulmonary bypass (CPB) is associated with the release of S100β and neuron-specific enolase (NSE) indicating cerebral cell injury. The purpose of the present study was to evaluate the effect of propofol and sevoflurane on S100β and NSE levels in patients undergoing coronary artery bypass grafting (CABG). MATERIALS AND METHODS Twenty male patients undergoing CABG were randomly allocat...

Thyroid hormones play an important role in cell growth and differentiation and regulation of oxygen consumption and thermogenesis. The effect of altitude and vitamin supplementation on thyroid hormone levels in animals or humans performing acute exhaustive exercise have not been investigated before. Therefore, we thought to test whether exhaustive exercise-induced stress with antioxidant supple...

background: considering the controversial information regarding the effects of perchlorate on thyroid function of high risk population as neonates, and given the high prevalence rate of thyroid disorders specially congenital hypothyroidism in our region, this study aims to investigate for the frst time in iran, the relationship between drinking groundwater perchlorate and cord blood thyroid hor...

BACKGROUND Because of the possible role of cytokines including interleukins (IL) in systemic non-thyroidal illnesses' (NTI) pathogenesis and consequently the frequently associated alterations in thyroid hormone (TH) concentrations constituting the euthyroid sick syndrome (ESS), we aimed in this research to elucidate the possible relation between IL-6 & IL-10 and any documented ESS in a cohort o...

 Background: To investigate thyroid function in preeclamptic patients in comparison with normal pregnant women. Methods: In this analytical cross-sectional study free Thyroxine (T4), and Thyroid Stimulating Hormone (TSH) levels were measured in 100 preeclamptic patients and were compared with Free T4 and TSH levels in 101 normal pregnant women in their third trimester of pregnancy. Patient...

There have been, and continue to be, reports of discordant free thyroxine (T4) 3 measurements when different free-T4 methods are applied to the same serum samples (1– 4 ). Our laboratory has attempted to identify some of the factors that contribute to these disparities. There are 4 separate components of serum T4: free T4, albumin-bound T4, transthyretin-bound T4, and thyroxine-binding globulin...

background beta-thalassemia is the most common hematology disease in human and leptin is one of the hormone that produce by adiposities cells. the purpose of this study was to investigate the relationship between serum leptin level and thyroid hormones in children with major beta-thalassemia. materials and methods this descriptive-cross sectional study was performed on 90 children aged 6-16 yea...

BACKGROUND Mitochondrial DNA (mtDNA) was reported as a pro-inflammatory agent. In our previous study, elevation of plasma mtDNA was revealed after cardiac surgery with cardiopulmonary bypass (CPB). Platelets were activated during the cardiac surgery and recent study revealed its ability to release mtDNA. Our present study postulated that the elevated plasma mtDNA comes from activated platelets,...

background: levothyroxine is commonly used in the treatment of patients with hypothyroidism. levothyroxine is often administered in the morning, on an empty stomach, to increase its absorption. however, many patients have trouble for taking levothyroxine in the morning. the aim of this study was to evaluate the effect of changing administration time of levothyroxine from before breakfast to bef...

the present study was conducted to evaluate the effect of feeding of different levels of metabolizable energy and of different crude protein levels on the performance and blood factors in japanese quails in their 5 to 41d old. the experiment was conducted as a 3×5 factorial arrangement, in a completely randomized design of four replicates with 40 quails per replicate. the fifteen dietary treatm...
