OBJECTIVE Following elimination of iodine deficiency in Iran, the program of screening for congenital hypothyroidism (CH) was established in 1998. The descriptive findings of the study are reported here. METHODS From February 1998 to June 2001, cord blood spot samples from 8 hospitals and a rural birth center in Tehran and Damavand were collected and(More)
INTRODUCTION Ubiquicidin (UBI) 29-41 is a cationic synthetic antimicrobial peptide fragment that binds preferentially with the anionic microbial cell membrane at the site of infection. This study was conducted to evaluate the potentiality of [(99m)Tc/Tricine/HYNIC(0)]UBI 29-41 prepared from lyophilized kits as an infection imaging agent in humans. METHODS(More)
INTRODUCTION It has been recognized that serotonin plays a main role in various pathological conditions such as anxiety, depression, aggressiveness, schizophrenia, suicidal behavior, panic and autism. 1-(2-Methoxyphenyl) piperazine pharmacophore, a fragment of the true 5-HT(1A) antagonist WAY100635, is found in numerous selective 5-HT(1A) imaging agents. In(More)
PURPOSE Radiolabeled somatostatin analogues are important tools for the in vivo localization and targeted radionuclide therapy of somatostatin-receptor-positive tumors. The aim of this study was to evaluate a new somatostatin analogue designed for the labeling with (99m)Tc: [6-hydrazinopyridine-3-carboxylic acid (HYNIC(0)), 1-Nal(3), Thr(8)]-octreotide(More)
Introduction: Ubiquicidin 29-41 (UBI) is a fragment of the cationic antimicrobial peptide that is present in various species including humans. The purpose of this study was to investigate radiochemical and biological characteristics of [6-hydrazinopyridine3-carboxylic acid (HYNIC)]-UBI 29-41 designed for the labeling with Tc using tricine as coligand.(More)
OBJECTIVE To assess the association of adherence to Dietary Approaches to Stop Hypertension (DASH)-style diet with development of metabolic syndrome (MetS) in children and adolescents. STUDY DESIGN Dietary data were collected using a valid and reliable food frequency questionnaire among 425 healthy subjects, aged 6-18 years. MetS was defined as the(More)
Face recognition is a non-contact biometric identification that tries to verify individuals automatically based on their images. Computational time and accuracy rate are important aspects to be considered for Face Recognition systems. Huasdorff distance is a dissimilarity measurement between two point sets which has been increasingly used for face(More)
BACKGROUND Considering the increasing trend of childhood obesity and subsequent burden of the disease in Iran and other countries and importance of early life intervention for achieving sustained effect on health of children and adolescents, this study aimed to investigate the effect of two different dose of folic acid on homocysteine (Hcy) level and(More)
Wind power stations, many located in remote areas; so they are characterized by weak grids and are often submitted to power system disturbance like faults. In this paper, the behaviour of a wind energy conversion system that uses the control of the rotor side converter (RSC) by three different methods under faulty conditions is presented. The behaviour of(More)
Introduction: Radioimmunotherapy (RIT) is a very promising new therapy for the treatment of recurrent B-Cell non-Hodgkin’s lymphoma (NHL). Iodine-131 is the most frequently used nuclide in clinical RIT, but its usefulness has been limited by dehalogenation of monoclonal antibodies labeled via conventional methods. To circumvent this problem, we have(More)
