Polarized Galactic synchrotron emission is an undesirable foreground for cosmic microwave background (CMB) experiments observing at frequencies $< 150$ GHz. We perform a combined analysis of observational data 1.4, 2.3, 23, 30 and 33 GHz to quantify the spatial variation polarized spectral index, $\beta^{pol}$, on $\sim3.5^\circ$ scales. compare results from different combinations address limit...

background: sterilization techniques could affect the characteristics of orthodontic wires. the aim of the present study was to evaluate the effect of steam and dry heat sterilization techniques on load-defl ection behavior of fi ve types of β-titanium alloy wires. materials and methods: the samples consisted of 30 straight lengths of fi ve types of β-titanium alloy wires: titanium molybdenum a...

Background Patients with beta thalassemia suffer from increased susceptibility to infections and putridity plays a major role in the patient's morbidity and mortality. The risk of transfusion-transmitted viral infection is well known in these patients. However, there is dearth of information about the seroprevalence of herpes simplex virus (HSV) infection in patients with beta thalassem...

Background: Are dietary patterns, substantiated by biomarkers, associated with semen quality? Materials and Methods: In 161 men of subfertile couples undergoing in vitro fertilization treatment in a tertiary referral clinic in Rotterdam, the Netherlands, we assessed nutrient intakes and performed principal component factor analysis to identify dietary patterns. Total homocysteine (tHcy), folate...

background: diabetes is a major public health problem. the development of new therapies that are able to improve glycemia management and even to cure diabetes is of great interest. in this study, protective effects of sodium tungstate against stz-induced beta-cell damages were investigated. methods: sixty rats were divided into six groups: control, diabetic, sodium tungstate treated diabetic ra...

background: oxidative stress in reproductive system leads to sperm dna damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. antioxidants such as carotenoids function against free radical damages. objective : the aim of this study was to determine the levels of lycopene, beta-carotene and retinol in s...

abstract background the purpose of this study was to assess the prevalence of major depressive and anxiety disorders in hemophilic and major beta thalassemic patients related to education of their mothers as a family’s agent. materials and methods a case-control study was performed on 34 major beta thalassemic patients. for each patient the control group was selected and matched (with age and s...
