Introduction: This study aimed to determine the traditional and relative overlap between Scopus and Web of Science databases in Endocrine System Diseases. Methods: This research is a descriptive survey and an applied study. Research population includes all articles retrieved from Scopus and Web of Science databases. 11 Descriptors and 120 sub-heading were searched in endocrine field in 2009....
The auditory middle latency response (AMLR) is characterized by two positive peaks (Pa, Pb) and two negative peaks (Na, Nb). The unpredictable nature of the second positive peak, Pb or P1, has made its diagnostic use problematic. Our purpose was to determine an appropriate combination of stimulating and recording variables that evoked a repeatable Pb in adults and children. Three experiments we...
The spontaneous emission rate of excitons strongly confined in quantum dots (QDs) is proportional to the overlap integral of electron and hole envelope wave functions. A common and intuitive interpretation of this result is that the spontaneous emission rate is proportional to the probability that the electron and the hole are located at the same point or region in space, i.e., they must coinci...
Heavy metals (HMs) immobilization in sewage sludge was investigated by using subcritical water technology (SCWT) in this study. The characteristics of sludge and toxicity of HMs were analyzed after SCWT process. The results showed that besides large reduction in sludge volume, SCWT had some positive effect on HMs dissolution into liquid phase, while the majority of HMs was still accumulated in ...
Background: Autoimmune diseases (ADs) are chronic conditions characterized by the loss of immunological tolerance to self-antigens. ADs are not rare and show variable patterns in different countries. In this study, we aim to investigate the prevalence of autoimmune disorders and pattern of polyautoimmunity among Iranian children with endocrinopathy. Methods: Overall 45 patients with early-onset...
Magnetoelectric (ME) composites that simultaneously exhibit ferroelectricity and ferromagnetism have recently gained significant attention as evident by the increasing number of publications. These research activities are direct results of the fact that multiferroic magnetoelectrics offer significant technological promise for multiple devices. Appropriate choice of phases with co-firing capabil...
The systemic toxicity of different combinations of heavy metal mixtures (HMMs) was studied according to equivalent proportions of the eight most common detectable heavy metals found in fish consumption in the Ningbo area of China. The ion mass proportions of Zn, Cu, Mn, Cr, Ni, Cd, Pb, and Hg were 1070.0, 312.6, 173.1, 82.6, 30.0, 13.3, 6.6, and 1.0, respectively. In this study, 10 experimental...
The toxicity of tetra and trimethyl and propyl lead compounds has been studied after their administration to rats and rabbits. The toxicity to rats of tetramethyl lead has been compared with tetraethyl lead when given by inhalation. Both tetramethyl and tetrapropyl lead were found to be considerably less toxic than trimethyl and tripropyl lead. There was evidence of a slow rate of conversion of...
