malignant pleural effusion is a common complication in certain malignancies. pleurodesis is the best option most of the time. the purpose of this study was to compare the choice of belomycin with povidone-iodine, which is not only determined by the efficacy of the agent but also by its cost, accessibility, safety, ease of administration and the number of administrations to achieve a complete re...
A Smarandache quasigroup(loop) is shown to be universal if all its f, g-principal isotopes are Smarandache f, g-principal isotopes. Also, weak Smarandache loops of Bol-Moufang type such as Smarandache: left(right) Bol, Moufang and extra loops are shown to be universal if all their f, g-principal isotopes are Smarandache f, gprincipal isotopes. Conversely, it is shown that if these weak Smaranda...
The application of stable isotope analysis (SIA) has become a standard scientific approach in Agricultural and Ecological researches and, more in general, in several disciplines such as biology, botany, zoology, organic chemistry, climatology, and nutrition. The main objectives of this paper are (1) to provide a simple definition of stable isotopes and (2) to illustrate analytical measurement m...
Background: Iodine deficiency and its related disorder such as goiter are endemic in Lorestan province. Following initiation of iodine deficiency control program in 1989, production, distribution and consumption of iodinated salt were begun. This survey was conducted in the framework of national monitoring survey in 2001 to find out the prevalence of goiter and urinary iodine level in order to ...
a detailed study of ostracoda changes against the stable isotopes of carbon and oxygen acrossthe cenomanian-turonian boundary mass extinction has been fully documented in one section, the south ofengland. this section comprises the uppermost cenomanian to lowermost turonian strata. the comparisonbetween the results obtained in this research and two rival models for the cenomanian-turonian bound...
Iodine deficiency remains a major health problem in the world, including some parts of Iran. It has been recognized that there is usually a close and inverse relationship between iodine in the soil and water and presence of endemic goiter. Calcium has been suggested as one of goitrogens, though the definite role, extent and mechanism particularly in human have not been studied. Serum protein-...
Background & Objective: Iodine deficiency was a public health problem in Iran before iodine supplementation. In order to evaluate the iodine status of school aged children in Zanjan, this survey was conducted in the frame work of national monitoring survey in 2001 to find the prevalence of goiter and urinary iodine level. Materials & Methods: 1200 schoolchildren, aged 7-10 years, were selected ...
Background and Objective: Iodized salt is one of the most important sources iodine in Iran. Former studies show that the iodine levels were insufficient both in distribution and consumption levels. The aim of this descriptive-analytical sectional study was to investigate the iodine content in table salts used by families covered by health services of Tehran University of Medical Sciences during...
Iodine availability for the maternal thyroid is reduced during pregnancy as a result of the loss of the nutrient by increased renal clearance, and competition by the fetoplacental unit. So with a marginal iodine intake, pregnancy constitutes a stimulus for both the maternal and fetal thyroids. On the other hand, iodine deficiency in the first trimester of pregnancy results in impaired developme...
pb-zn deposits in the kurdistan region, northern iraq, have occurred mainly as a stratabound and open-space filling ore bodies. they are hosted by dolostone and dolomitic-limestone of platform carbonates. the ore deposits at the studied dure and lefan areas are respectively hosted by kurra chine (upper triassic) and bekhme (upper cretaceous) formations. pyrite, sphalerite and galena are the maj...
