Background: The existence of some radionuclides in soil and some building materials produce a β-γ radiation field, which in some regions the exposure of these radionuclides to human is high. Materials and Methods: The air-absorbed dose, indoor and outdoor annual effective dose of soil and some building material samples (ceramic, granite, gypsum, etc.). The samples were collected from 3...
b-cyclodextrin glucosyl transferase (b-CGTase) hydrolyses starch to produce b-cyclodextrin by transglycosylation (cyclization) activity. The conventional method for detection of b-CGTase activity is based on detecting starch hydrolysis by iodine staining. This method reveals all amylolytic enzymes, but can not discriminate them. In the present study, we introduce a new method for specific detec...
introduction: somatostatin receptors expressed on a wide range of human tumors, are potential targets for the peptide receptor radionuclide therapy (prrt). in this study, 177lu-[dota-dphe1, tyr3]octreotide (177lu-dotatoc) as an agent for prrt was prepared and its biodistribution was studied in rats. methods:the best condition for the preparation of the 177lu-dotatoc radiolabeled complex was det...
