The aim of this study was to determine the iron status of infants who consumed porridge cooked in water with added ferrous sulphate. A total of 234 infants, aged 6-12 months, were recruited from 36 nurseries in the Democratic Peoples Republic of Korea (DPRK North Korea) and randomly divided into iron (Fe) and placebo groups. At baseline, almost half the children had Hb<110 g/L and no significan...

forty neonate calves were used in this study. the animals were divided into two treatment (n = 20) andcontrol (n = 20) groups. in the treatment group, oral iron as ferrous sulphate was supplemented to each calf atthe dose of 150 mg/day for 28 days, from the birthday. blood sampling was taken from jugular veinimmediately after birth and on days 7, 14, 21 and 28 after birth. significant differenc...

A Raman spectroscopic study of aqueous solutions of Li2S04, LiNaSOq and LiKS04 as function of concentration and temperature has been performed. From a band profile analysis of the internal modes of the sulphate ion , the spectroscopic association constant has been calculated at different temperatues. It has been also possible to measure the diasivity coefficients for Li2S04 in bulk solutions an...

Crystal growth in native collagen gels has been used to determine the role of extracellular matrix macromolecules in biological calcification phenomena. In this system, type I collagen gels containing sodium phosphate and buffered at pH 7.4 are overlayed with a solution containing CaCl2. Crystals form in the collagen gel adjacent to the gel-solution interface. Conditions were determined which p...

Binding of basic fibroblast growth factor (bFGF) to the extracellular matrix of cultured bovine aorta smooth muscle cells is likely to be mediated via heparan sulphate, since not only exogenous addition of heparan sulphate to the culture medium but also pretreatment of the cells with heparitinase (but not chondroitinase ABC) resulted in loss of binding. Comparison of the affinity of bFGF to var...

Fe absorption from water-soluble forms of Fe is inversely proportional to Fe status in humans. Whether this is true for poorly soluble Fe compounds is uncertain. Our objectives were therefore (1) to compare the up-regulation of Fe absorption at low Fe status from ferrous sulphate (FS) and ferric pyrophosphate (FPP) and (2) to compare the efficacy of FS with FPP in a fortification trial to incre...

H]glucosamine has been used to label metabolically keratinocyte cell-surface glycoconjugates. The major labelled bands identified on sodium dodecyl sulphate/polyacrylamide gels had apparent molecular weights of greater than 250000, and 150000-80000. Most of these components were trypsin-sensitive, indicating that the label was protein-bound. Some of the labelled components were shown to be prot...

Application of natural dyes in textile coloring has been widely used because it is more environmentally friendly than synthetic and able to produce various colors from one dye. In this study, cotton fabric was treated with chitosan at different concentrations (0, 0.25%, 0.5%, 1%) determine its effect on the color fastness using mango leaves extract as dyes. Fastness ironing, washing sun drying ...
