After total hip and knee replacement arthroplasty, patients may become anaemic and may be prescribed oral iron. There is, however, no published evidence that this is of benefit when used postoperatively. We treated 72 patients who were anaemic after primary total hip and knee arthroplasty by randomly allocating them to receive six weeks of either oral ferrous sulphate (35 patients) or a placebo...

The objective of this study was to evaluate iron bioavailability of maize genotypes, and analyze the correlation between in vitro and in vivo methods. Dialysable iron was analyzed in 13 genotypes from which 5 were selected for the biological assay. Mean iron content of the genotypes (n = 13) was 17.93 +/- 2.93 mg kg(-1). Phytate varied from 0.77% to 1.03%; phytate: iron molar ratio from 30.64 t...

This paper describes studies on the recovery of metals from spent hydro-processing catalyst using mixed acidophilic culture in presence of pyrite. This culture was initially grown in the 9K medium (absence of 9 g/L Fe(II)) where ferrous sulphate (FeSO4) was replaced by pyrite, and then applied in this bioleaching study. Bacterial action on pyrite catalysed the formation of ferric ion (Feþ3), pr...

A non-haem iron protein was isolated from an extract of soya-bean nodule bacteroids by a procedure including protamine sulphate and heat precipitation followed by chromatography on DEAE-cellulose. The purified protein contains non-haem iron and acid-labile sulphur and exhibits a spectrum with a rather broad absorption shoulder in the region 380-440nm and a more prominent peak at 280nm. From sed...

This field experiment was carried out at Horticultural Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar (U.K.), India, during two consecutive years 2010 and 2011 on 7 years old peach trees cv. Sharbati. The experiment was designed in RBD to study the effect of foliar spraying of boron, zinc and iron and its combination on fruit growth pattern and yield attributing ...

Streptokinase is an extracellular protein secreted by various strains of streptococci and is used clinically as an intravenous thrombolytic agent for the treatment of acute myocardial infarction. It is well established that the fibrinolytic activity of streptokinase originates in its ability to activate plasminogen. The present investigation was carried out to determine the extent of streptokin...

To study the pathogenicity of Malassezia, the agent of pityriasis versicolor, it is necessary to obtain the mycelial form in vitro. A range of different components and conditions were tested to induce yeast cells of the organism to produce mycelia in vitro using different culture media. A mycelial culture medium was developed that consisted of bacteriological peptone, glucose, yeast extract, ox...

Oxidation of tyrosine in the presence of bovine lens proteins leads to the formation of brown or black melanoproteins. Both tyrosinase and the oxidizing system of ferrous sulphate-ascorbic acid-EDTA are effective. The fluorescence of the lens proteins is both altered and enhanced by the tyrosine-oxidizing systems. Their fluorescence spectra resemble those of urea-insoluble proteins of human cat...

Nanoparticles of titanium dioxide doped with Fe2+ ions have been synthesized via sol-gel technique using Titanium tetraisopropoxide (TTIP) and ferrous sulphate as a precursors. The synthesized nanopowders were characterized by Powder X-ray Diffraction (PXRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), Ultraviolet Visible (UV-Vis) and Photoluminescence (PL) Spectrosco...
