background and aims: nowadays introduction of regular blood transfusion therapy has obviously improved the life expectancy of patients with thalassemia. however, these patients face with newer challenges which influence their quality of life (qol). in this study, the aim of this study was to measure qol among patients with β-thalassemia major (β-tm). methods: a cross-sectional study was done at...
This study aimed to investigate the effect of enamel caries lesion baseline severity on fluoride dose-response under pH cycling conditions. Early caries lesions were created in human enamel specimens at four different severities (8, 16, 24, and 36 h). Lesions were allocated to treatment groups (0, 83, and 367 ppm fluoride as sodium fluoride) based on Vickers surface microhardness (VHN) and pH c...
An experiment was performed at the Miyandoab Agricultural Research Station to study yield and water use efficiency of furrow and tape irrigation systems in one-row and two-row planting patterns, and to investigate density of grain corn SC704. The experimental design was a completely randomized block arranged in Strip Split Plots with three replications in 2010. Irrigation treatments were applie...
