To study the ionic basis of salt sensitivity in hypertension, Tl_-, 31p-, and 'Na-nuclear magnetic resonance techniques were used to measure cytosolic free calcium (Ca1), pH (pH,), free magnesium (Mg1), and sodium (Na4) in erythrocytes of essential hypertensive subjects (n = 19). Individuals were studied for 2 mo each on low(UNaV < 50 meq/d) and high(UNaV > 200 meq/d) salt diets, with the conco...
BACKGROUND Although low magnesium levels have been associated with an increased mortality in dialysis patients, they are kept low by routinely-used dialysates containing 0.50 mmol/L magnesium. Thus, we investigated the impact of a higher dialysate magnesium concentration on mortality. METHODS 25 patients on high dialysate magnesium (HDM) of 0.75 mmol/L were 1:2 matched to 50 patients on low d...
Background: Over the past two decades we have seen a marked increase in the survival of very low birth weight infants. This increase in survival has been attributed to increased use of corticosteroids, regionalization of perinatal care, improved methods of mechanical ventilation, availability of exogenous surfactant, and improved nutritional therapy. However, the reduction in mortality has not ...
A new method for isolating blood leukocytes and measuring intracellular leukocyte magnesium is based on three successive centrifugations (1300 x g, 5 min, 22 degrees C), with no use of Ficoll, followed by two washes. We express the leukocyte magnesium concentration in micromoles of magnesium per gram of protein. Magnesium is measured by atomic absorption spectrophotometry, protein by the classi...
in order to evaluation the effects of different soil fertility systems on chickpea seed quality, field experiments were carried out in sanandaj agriculture research station of iran in 2007 and 2008 growing seasons. experimental units were arranged in split-split plots based on randomized complete blocks with three replications. green manure levels considered main plots, base fertilizer compound...
Many studies suggest the fluctuation of the serum level of zinc and magnesium in diabetic patients compared with healthy individuals and etiological role of these elements in the pathogenesis of diabetes. This study aimed to measure the serum level of zinc and magnesium in three groups of healthy individuals, patients with diabetes, and patients with metabolic syndrome and relationship of these...
in this study the effect of nitrogen form and different oxygen levels on growth and development and macronutrients concentrations in lettuce plants was investigated. this investigation showed that sole ammonium application caused fresh and dry weight reduction of shoot and root in lettuce plant. but different oxygen levels had no effect on them. nitrogen concentration of shoot was higher in amm...
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
High temperature thermal treatments were used to modify the cation order in several tantalate and niobate members of the Pb(Mg1/3Nb2/3)O3 (PMN) family of relaxors. The observation of complete 1:1 structural order in several compositions, and the refined cation occupancies of well-ordered samples conflict with the predictions of the “space charge” model, and support the “random site” description...
