two new potential magnetic resonance imaging contrast agents, gd-hematoporphyrin (gd-h) and gd-tetra-carboranylmethoxyphenyl-porphyrin (gd tcp), were synthesized and applied to nude mice with human melanoma (mm 138) xenografts. these agents showed a high relaxivity because of their greater potential to coordinate water molecules. the reduction of t1 relaxation times of 16 and 21% was observed i...

Determination of the relative biological effectiveness (RBE) of Auger electrons is a challenging task in radiobiology. In this study, we have estimated the RBE of internal conversion (IC) and Auger electrons released during Gadolinium neutron capture reaction (GNCR) by means of biological weighting functions (BWFs) with microdosimetric approach. Regarding the different distribution of Gadoliniu...
نمونه های بسبلوری gd(ba2-xndx)cu3o7+δ{gd(band)123} , gd(ba2-xlax)cu3o7+δ{gd(bala)123} , nd(ba2-xprx) cu3o7+δ{nd(bapr)123} با مقادیر آلایش 0.0≤ x ≤ 0.8 به روش واکنش حالت جامد ساخته شده است. طیفهای xrd ترکیبات ساخته شده نشان می دهد که تمامی نمونه های gd(bala)123 تک فاز 123 هستند, اما در ترکیبات nd(bapr)123 و gd(band)123 وجود ناخالصی به ازای x=0.8 کاملا مشهود است. حد حل پذیری در نمونه های gd(band...
دراین پایان نامه، ابتداساختارهای نامبو- پواسون از بالاترین مرتبه را برروی گروه های لی حقیقی سه بعدی محاسبه کرده ایم، توانسته ایم با استفاده از یک قضیه کاربرد فیزیکی برای ساختار نامبو- پواسون 3- تایی ، برای یک نمونه ازجبرهای لی نظیرگروه های لی سه بعدی را بیابیم. به روش مشابه، ساختارهای نامبورا بر روی گروه های لی چهاربعدی برای اولین بارمحاسبه کرده ایم.درادامه با تعمیم قضیه ی مذکوردرچهار بعد، کارب...
Background: The monoclonal antibody, C595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (Gd-cDTPAa) to produce Gd-DTPA-C595 and used as specific breast cancer cell line (MCF-7) contrast agents in magnetic resonance imaging (MRI). Methods: After incubation of breast cancer cell line (MCF-7), with different contrast agents (G...

Background: Graves’ disease (GD), a highly rampant autoimmune disorder of the thyroid gland, is responsible for 60-80% of the clinical cases of hyperthyroidism. Over the past decades, genetic association studies have identified several GD susceptibility loci in CTLA-4, TSHR and major histocompatibility complex regions. The information on the association between the human leukocyte antigens (HLA...
The mononuclear Gd(III) complex, [Gd(L)3(H2O)5] (where L is alizarin yellow R (NaC13H8N3O5)), has been prepared in H2O under reflux condition. The Gd(III) complex has been characterized by elemental analysis and spectroscopic methods (UV–Vis and FT–IR). The Gd2O3 nanoparticles were prepared by the calcination of the Gd(III) complex in air at different temperatures up to 600 °C for 2 h. The calc...
