asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
UNLABELLED The alteration of 99mTc-labeled diethylenetriaminepentaacetic acid (DTPA) transalveolar clearance in an initial phase of radiation lung injury was experimentally investigated. METHODS Fourteen dogs were irradiated to the hemithorax with a single dose of 20 Gy. A DTPA radioaerosol study was performed before irradiation and on day 12 after irradiation. On day 14, the DTPA study was r...
The in vivo(212)Pb/(212)Bi generator is promising for application in targeted alpha therapy (TAT) of cancer. One main limitation of its therapeutic application is due to potential release of (212)Bi from the radioconjugate upon radioactive decay of the mother nuclide (212)Pb, potentially leading to irradiation of healthy tissue. The objective of the present work is to assess whether the chelate...
OBJECTIVE-To evaluate use of gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA) to estimate glomerular filtration rate (GFR) by plasma clearance and use of an ELISA as the method of Gd-DTPA quantification. ANIMALS-16 dogs of various sexes and breeds (12 dogs were clinically normal, and 4 dogs were polyuric and polydipsic with no other clinical or biochemical abnormalities). PROCEDURES-GFR...
UNLABELLED Neuroendocrine tumors (NETs) can be visualized using radiolabeled somatostatin analogs. We have previously shown the clinical potential of (64)Cu-DOTATATE in a small first-in-human feasibility study. The aim of the present study was, in a larger prospective design, to compare on a head-to-head basis the performance of (64)Cu-DOTATATE and (111)In-diethylenetriaminepentaacetic acid (DT...
Determination of copper (Cu) availability in soils is important in preferment quality and quantity of agricultural crops. To this aim, suitable extractant must be introduced. The objective of this greenhouse experiment was to evaluate several extractants to predict available Cu of cultivated bean, in 10 calcareous soils, untreated and treated with municipal sewage sludge. After one month of inc...
In the presented work, possibility of direct synthesis LDH (layered double hydroxide) on AZ91 surface in presence a chelating agent (diethylenetriaminepentaacetic acid - DTPA) is reported. Conversion layer nanocontainers were formed under ambient pressure conditions without carbonate addition electrolyte. The obtained was characterized using experimental (SEM, XRD, TGA, XPS, Raman, etc.) and co...
This study was conducted to investigate nutritional status and some quality aspects of greenhouse cucumber in Qom province. After selecting 20 greenhouses, concentrations of macro- and micronutrients as well as lead (Pb) and cadmium (Cd) in soil and plant were measured. In addition, some fruit quality attributes were determined. Phosphorus (P) and potassium (K) concentrations in soils were much...
Arsenic (As), cadmium (Cd), and copper (Cu) are the primary inorganic pollutants commonly found in contaminated soils. The simultaneous stabilization of three elements is a preferred approach for mixture-contaminated soils which has received extensive research attention. However, few studies have focused on immobilization efficiency single amendment elements. In this study, phosphate, red mud, ...
PURPOSE: Hepatobiliary contrast agents add an additional form of image contrast to hepatic magnetic resonance (MR) imaging, allowing differentiation of tumors which have functional hepatic and biliary components from those without. Gd-EOB-DTPA has sufficiently significant elimination via the hepatobiliary pathway to make it a feasible contrast agent in the time allotted to a typical clinical ab...
