complexes of benzo-15-crown-5 macrocycle with li+ and cs+ ions were investigated by 7li and 133cs nmr in a number of nonoqueous solutions. the resulting 1:1 complex with li+ ion was found to be much more stable than that with cs+ ion. with the exception of pyridine solutions the stabilities of the complexes varied inversely with the gutmann donor number of the solvents. some indirect evidence f...
Introduction: Developing new radiosynovectomy agents is of great importance due to the aging of human populations around the world and increasing the incidence of inflammatory diseases. In this work, Sm-153 chitosan agent was developed for the first time in our country and preparation and quality control of the compound is described. Methods: Sm-153 chloride was ob...
67Gallium-bleomycin complex (67Ga-BLM) was prepared using Thakour method. Radio-thin-layer-chromatography of prepared complex showed A2 and B2 radiopeaks with Rf at 0.7 and 0.4 respectively with a purity of above % 95. Tissue uptake of 67Ga-BLM and 67GaCl3 in twelve tissues including tumor, blood, liver, lung, spleen, muscle, skin, heart, kidney, colon, colon content ,bladder and the tota...
Developing new bone pain palliation agents is a mandate in handling end-stage cancer patients around the world. Possibly, Lu-177 ethylenediaminetetramethylene phosphonic acid (177Lu-EDTMP) is a therapeutic agent which can be widely used in bone palliation therapy. In this study, 177Lu-EDTMP complex was prepared successfully using synthesized EDTMP ligand and 177LuCl3. Lu-177 chloride was obt...
Aim and Background:Taxol is a known substrate for P-glycoprotein, which induces drug resistance to cancerous cells. Therefore radiolabeled taxol can be a suitable probe for imaging of the P-glycoprotein transport ability to determine drug resistance. The aim of this study was to provide labeled taxol and to determine the rate of uptake in the tumor to evaluate the location of the tumor and the ...
the biopolymer-based nanocomplexes are a group of nanocapsules that are used for encapsulation and control delivery of nutraceuticals. they are formed by binding of proteins and polysaccharides. in this study, complex formation between pectin and sodium caseinate was taken place by addition of pectin solutions(0.2, 0.45 and 0.7 % w/v) into the caseinate solutions (0.5, 1 and 1.5 % w/v) and adju...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
Introduction: 5-HT1A receptor is related with a variety of neuropsychiatric disorders. . In this study a phenolic analogue derived from DWAY [Desmethyl WAY-100635 (N-(2-(1-(4-(2-methoxyphenyl)piperazinyl)-ethyl))-N-(2-pyridinyl) cyclohexanecarboxamide)] is used to design the desired structure of 5-HT1A receptor imaging agents after labeling with [99mTc (CO) 3(H2O) 3] + cor...
