background/objective: hyperphosphatemia is the consequence of end stage renal failure. inadequate control of serum phosphorus results in elevated ca × p product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification. in this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis pat...
There were investigated the seasonal and spatial dynamics of content nutrients in lakes Opechen’ system. It has been established that reservoirs urbanized territory, addition to external load, depends significantly on their migration from bottom sediments under oxygen deficiency reduction conditions. The concentration dissolved value redox potential within 0–16.2 mg/dm3 -129÷295 mV. Dissolved (...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
Marriott and Howland (1), in 1916, showed that in the blood of uremic patients the serum calcium is low but that there is an increased concentration of inorganic phosphorus. That there might be some relation between the rise of phosphate and the fall of calcium was first suggested by Binger (2), who injected solutions of 0-phosphates intravenously into dogs and observed an elevation of inorgani...
sediments from the southern caspian sea, located in iranian coast were examined on the basis of p-fractionation (five forms of phosphorus) by a sequential extraction scheme. ninety-six surface sediment samples (for each season with triplicate) were collected from eight sampling transects in 10 and 100 m depths during summer and winter in 2010-2011. the result indicated that the most abundant fo...
Background/Objective: Hyperphosphatemia is the consequence of end stage renal failure. Inadequate control of serum phosphorus results in elevated Ca×P product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification. In this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis patie...
Tree uprooting creates multiple microsites that can be effective on soil heterogeneity. In order to investigate the soil features in pit and mound location, twenty hectare areas of Tarbiat Modares University Experimental Forest Station studied that is located in Mazandaran province, in the north of Iran. Numbers of thirty four uprooted trees were found in study areas. Five microsites were con...
BACKGROUND, AIM, AND SCOPE Recent assessments of water quality status have identified eutrophication as one of the major causes of water quality 'impairment' not only in the USA but also around the world. In most cases, eutrophication has accelerated by increased inputs of phosphorus due to intensification of crop and animal production systems since the early 1990 s. Despite substantial measure...
