Chronic Kidney Disease of unknown etiology (CKDu) has escalated into an epidemic in North Central Province (NCP) and adjacent farming areas in the dry zone of Sri Lanka. Studies have shown that this special type of CKD is a toxic nephropathy and arsenic may play a causative role along with a number of other heavy metals. We investigated the hypothesis that chemical fertilizers and pesticide cou...
In vitro subunit hybridisation is a usehl technique for exploring inter-subunit interactions in oligomeric enzymes [I]. In order to explore the basis of allosteric bebaviour in glutamate dehydrogenase from Clmtridiurn syrnbimurn, hybrid hexamers of mutants, VIZ. triple mutant, K89L/A163G/S380A [2] and C320S [3] have been constructed. The mutant C320S is hUy active and shows normal allosteric pr...
: World population has been continuously raised and therefore due to this fact new source of foods, particularly proteins, are in demand. In recent years, single cell protein has been considered as an accepted substitute for animal and plant proteins. In this study, single cell protein production was studied in a batch submerged culture using Aspergillus niger PTCC5012. Experimental design was ...
The use of potassium ferrate(VI) as an alternative water treatment chemical for both drinking water and sewage treatment has been studied and is reported in this paper. The performance of potassium ferrate(VI) was evaluated in comparison with sodium hypochlorite (NaOCl) and NaOCl plus ferric sulphate (FS) and aluminium sulphate (AS). The effects of the dosages of ferrate(VI), NaOCl and FS/AS an...
The gross alpha (α) and beta (β) activities and trace heavy elemental concentrations have been determined in Single Super Phosphate (SSP) and Nitrogen Phosphorous Potassium (NPK) fertilizers samples used for agricultural purposes in Nigeria. Cultivated farm soil samples from two regions (north and south) in the country and samples of phosphate rocks were also analyzed for gross α and β radioact...
1. The mechanism of sulphite and sulphate permeation into rat liver mitochondria was investigated. 2. Extramitochondrial sulphite and sulphate elicit efflux of intramitochondrial phosphate, malate, succinate and malonate. The sulphate-dependent effluxes and the sulphite-dependent efflux of dicarboxylate anions are inhibited by butylmalonate, phenylsuccinate and mersalyl. Inhibition of the phosp...
phosphate solubilizing bacteria are a group of plant growth promoting rhizobacteria (pgpr) that increase growth and yield of plant by enhancing insoluble phosphates. in this study, a greenhouse experiment was carried out to investigate the effect of phosphate solubilizing bacteria and phosphorous fertilizer on the yield and chemical components of sesame. this experiment was conducted in factori...
OBJECTIVES Calcium oxalate kidney stones are more common in patients with Crohn's disease (CD). The aims of this study were to verify the prevalence of the main risk factors for calcium oxalate nephrolithiasis in patients with CD and to evaluate the degree of urinary relative supersaturation for calcium oxalate (CaOx), dihydrogen uric acid (DHUA) and monohydrogen calcium phosphate (MHCaP). SUBJ...
The Haft Sandogh alunite deposit is located in the northwest of Takestan (about 60 Km west of Qazvin), and is a part of large Takand alunite deposit. Mineralogical and field study reveal that there is a zonation in the alteration zones of the Haft Sandogh deposit and surrounding area including silica zone in the central part, and quartz-alunite (quartz alunite), kaolinite and propylitic formed ...
