UNLABELLED We investigated the distribution, stability and radiotoxicity of 125I-oligodeoxyribonucleotides (125I-ODN) in human fibrosarcoma HT-1080 cells to study the radiotoxic effects of the Auger electron emitter 125I delivered to the cells by ODN. METHODS We delivered 125I-ODN into the cells via complexing with a liposomal delivery system. To assess the intracellular distribution and stab...
The binding, internalization and degradation of 200 pM monoiodinated human atrial natriuretic factor-(99-126) (125I-hANF) by cultured bovine aortic endothelial cells (BAECs) were studied at 37 degrees C. 125I-hANF was rapidly cleared from the extracellular medium (t1/2 approximately 10 min), whereas preincubation of the cells in the presence of 20 mM-NH4Cl or 0.2 mM-chloroquine resulted in a si...

Introduction Dose calculation of tumor and surrounding tissues is essential during prostate brachytherapy. Three radioisotopes, namely, 125I, 103Pd, and 131Cs, are extensively used in this method. In this study, we aimed to calculate the received doses by the prostate and critical organs using the aforementioned radioactive seeds and to investigate the effect of scattering contribution for the ...
سابقه و هدف: درمان گلیوم خوشخیم یکی از مشکلات جراحی اعصاب است. با توجه به گزارشاتی از موفقیت درمان چشمههای موقت 125I در بیماران low grade glioma (LGG) و عدم گزارش از تجربه آن در کشور، این تحقیق بر روی مراجعین به بیمارستان شهدا تجریش که به علت LGG قبلاً تحت درمان جراحی یا رادیوتراپی قرار گرفته بودند و پاسخ به درمانهای قبلی نداشتند انجام شد. مواد و روشها: مطالعه به روش case series روی کلیه بیما...
PURPOSE To develop a superior VAChT imaging probe for SPECT, radiolabeled (-)-OIDV and (+)-OIDV were isolated and investigated for differences in their binding affinity and selectivity to VAChT, as well as their in vivo activities. PROCEDURES Radioiodinated o-iodo-trans-decalinvesamicol ([125I]OIDV) has a high binding affinity for vesicular acetylcholine transporter (VAChT) both in vitro and ...
Theoretical and experimental dosimetric studies have been supplied useful information on the dependence of the brachytherapy source geometry and materials (1-5). Usually, Monte Carlo method is used to define dose distribution function, the radial dose variation, and the dose calculation close to the source in brachytherapy. Chen et al. (6). calculated the distribution of absorbed dose around co...
