OBJECTIVE The aim of this study was to compare the renal function measured with either 99mTc-DTPA or 99mTc-EC dynamic scintigraphies with that measured using 99mTc-DMSA static scintigraphy. METHODS the values of relative renal function measured in 111 renal dynamic scintigraphies performed either with 99mTc-DTPA (55 studies) or with 99mTc-EC (56 studies) were compared with the relative functi...

Phytate (myo-inositol (1, 2, 3, 4, 5, 6) hexakisphosphate), a naturally compound formed during maturation of plant seeds and grains is a common constituent of plant-derived foods. The major concern about the presence of phytate in the diet is its negative effect on mineral uptake. Minerals of concern in this regard would include Zn 2+, Fe 2+/3+, Ca 2+, Mg 2+, Mn 2+, and Cu 2+. Especially zinc a...

Background. Phytate (myo-inositol hexakisphosphate) is a naturally occurring compound in plants. Due to chelation of several dietary minerals, it acts as a potent anti-nutrient in foods. Degradation of phytate has previously been found to significantly improve absorption of nutritionally important minerals, such as iron and zinc, in the human intestine. By removing regulatory genes for phytase ...

SYMPOSIUM PROCEEDINGS I965 the ions with which they are associated (mainly Ca2+, Mg2+, Mn2+, K+ and H + in natural phytates) and on the level of Ca in the diet. Thus, native phytates, free phytic acid, sodium and calcium phytates and commercial ‘phytin’ (a Ca-Mg phytate) do not necessarily behave in the same way. Vitamin D probably enhances the utilization of phytate P in two ways, by increasin...

Demand for bean products is growing because of the presence of several health-promoting components in edible bean products such as phytates. Phytates are a naturally occurring compound, which is distributed widely in all cells of legume plants. Clinical studies have suggested that these health-promoting components, phytates, affect the immune system to protect the human body against cancers, an...

This study aimed to prepare a novel radiopharmaceutical for the detection of brain disorders at early stages in susceptible patients.Promazine hydrochloride was labeled with 125I by direct electrophilic substitution reaction high labeling yields 92.6 ± 3.24 %. The yield and vitro stability 125I-promazine were determined paper electrophoresis, chromatography (PC) High performance liquid (HPLC). ...

Pathological calcification generally consists of the formation of solid deposits of hydroxyapatite (calcium phosphate) in soft tissues. Supersaturation is the thermodynamic driving force for crystallization, so it is believed that higher blood levels of calcium and phosphate increase the risk of cardiovascular calcification. However several factors can promote or inhibit the natural process of ...

There is a distinct possibility that phytate negatively influences protein and energy utilisation in poultry and, as these influences would be ameliorated by phytase, there are substantial, practical implications. Despite several thousand scientific papers and a rapidly growing market the use of phytase and the importance of phytate in practical poultry nutrition remains an area of some confusi...
