INTRODUCTION L,L-ethylenedicysteine (EC) is a new carrier of technetium Tc 99m (99mTc) with a lower affinity to plasma albumin in comparison with diethylenetriamine pentaacetic acid (DTPA). We compared 99mTc-EC scan with 99mTc-DTPA scan in diuretic renography for patients with obstructive uropathy. MATERIALS AND METHODS Thirty-three patients with upper urinary tract obstruction were randomly ...

The possible use of Lactobacillus brevis IBRC-M10790 with degrading phytase activity was investigated in sourdough and Barbari bread –using 20 and 30% of sourdough in the formulation- in order to enhance the nutritional bioavailability, and the efficiency of the bacteria in decreasing phytate via using in sourdough was compared to yeast. Results showed that L. brevis ...

In the present study phytase, phytate and protein content were determined in twenty wheat varieties. Among twenty wheat varieties, LOK-1 variety was found to have higher content of phytase, phytate and protein. During the study, phytase activity was 197.30±0.65 to 2132.77±0.29 nM/min/g, phytate 2.90±0.35 to 7.07±0.09 and protein 77.07±0.64 to 148.40±0.31 mg/g found, respectively through differe...

The role of bacterial, dietary and intestinal phytases (EC 3.1.3.8) in the hydrolysis of phytate was investigated in the golden hamster and rat by assaying phytase in the small intestine and by measuring the disappearance of phytate from the stomach and large intestine, using chromium oxide as an insoluble solid-phase marker. It was confirmed that an active phytase was present in the proximal t...

The inefficient digestion of phytate phosphorus by fish has created environmental concerns associated with phosphorus pollution from aquaculture production facilities. To further complicate this situation, phytate is known to chelate minerals and proteins, making them nutritionally unavailable. The enzyme phytase degrades phytate into inorganic phosphorus, which can be directly utilized by fish...

phosphorus (p) is a macro mineral in broiler nutrition. in growing broilers, besides its requirement for proper bone development, it is also involved in almost all metabolic processes. poor p availability results in decreased productivity and poor health status.phosphorus availability from plant derived feeds is affected by an anti-nutritional factor “phytate”, which forms a variety of insolubl...

El hiperparatiroidismo primario (HPTP) es la principal causa de hipercalcemia en pacientes no hospitalizados, estando causado el 85-90% los casos por un adenoma solitario. La cirugía radioguiada paratiroides (CRGP), como técnica GOSTT (Guided intraOperative Scintigraphic Tumor Targeting), utiliza SPECT-TC con 99mTc-MIBI elección. PET-TC 18F-Colina (18FCH) puede emplearse negativo, obteniéndose ...

1. Partial hydrolysates of phytic acid, containing mixtures of different polyphosphate esters of inositol, have been shown to be potent inhibitors of the calcification in vitro of ricketic rat cartilage and rat aorta; phytate itself was inert. 2. Phytic acid, as well as its hydrolysates, when injected parenterally, prevented aortic calcification in rats with vitamin D intoxication. 3. The rat a...

BACKGROUND Molecular breast imaging (MBI) performed with 99mTc sestamibi has been shown to be a valuable technique for the detection of breast cancer. Alternative radiotracers such as 99mTc maraciclatide may offer improved uptake in breast lesions. The purpose of this study was to compare relative performance of 99mTc sestamibi and 99mTc maraciclatide in patients with suspected breast cancer, u...
