choline oxidase (chox) was chosen as a model enzyme for evaluating the performance of cnts’ functional groups for development of enzyme electrodes. cnts were functionalized with carboxylic acid, amine or amide groups. carboxylic acid, amine and amide functionalized cnts were obtained by acid treatment, ethylenediamine or tetraethylenepentamine chemically modification and ammonia plasma treatmen...

INTRODUCTION The purpose of this research is to evaluate the prospects for the use of 4-(trans-18F-fluoranylmethyl)-N-[2-[4-(2-methoxyphenyl)piperazin-1-yl]ethyl]-N-pyridin-2-ylcyclohexane-1-carboxamide (18F-Mefway) in comparison to 18F-trans-4-fluoro-N-2-[4-(2-methoxyphenyl)piperazin-1-yl]ethyl]-N-(2-pyridyl)cyclohexanecarboxamide (18F-FCWAY) for the quantification of 5-HT1A receptors in human...

This article provides a brief overview of the 18F isotope production using Cyclone-30 cyclotron and two liquid targets with volume 0.5 2.0 ml, water enriched 18O was used as target material. The obtained for serial [18F]FDG radiopharmaceutical supply this medicine to operating PET centers in Almaty. also experimental syntheses [18F]PSMA-1007 Na[18F]F assess possibility implementation these medi...

objective(s): use of a positron emission tomography (pet)/single-photonemission computed tomography (spect) system facilitates the simultaneousacquisition of images with fluorine-18 fluorodeoxyglucose (18f-fdg) andtechnetium (99mtc)-tetrofosmin. however, 18f has a short half-life, and 511kev compton-scattered photons are detected in the 99mtc energy window.therefore, in this study, we aimed to ...

Early diagnosis of low grade glioma has been a challenge to clinicians. Positron Emission Tomography (PET) using 18F-FDG as a radio-tracer has limited utility in this area because of the high background in normal brain tissue. Other radiotracers such as 18F-Fluorocholine (18F-FCH) could provide better contrast between tumor and normal brain tissue but with high incidence of false positives. In ...
