Introduction: There are many ways to treat cancer and pain relief. One of the methods is radiopharmaceutical therapy. Indium 111-rituximab contains the radioisotope indium-111 and rituximab. The Indium-111, after decay, emits gamma rays with energies of 245 KeV and 171 KeV, and beta-radiation of 26 KeV. In this study, the absorbed dose of 111In-Rituximab in human body was calcu...

BACKGROUND Our objective was to compare 111In- or 64Cu-DOTA-trastuzumab Fab fragments for imaging small or large s.c. tumor xenografts in athymic mice that display a wide range of human epidermal growth factor receptor-2 (HER2) expression using microSPECT/CT or microPET/CT. METHODS Trastuzumab Fab were labeled with 111In or 64Cu by conjugation to 1,4,7,10-tetraazacyclododecane N, N', N'', N''...

introduction: auger electron based radioimmunotherapy (rit) using 111in-dota-trastuzumab (111in-dota-antiher2) feasibility was studied in vitro on a her2/neu positive cell line, skbr3. methods:111in-dota-antiher2 was prepared according to the optimized conditions followed by quality control tests including radiochemical purity; immunoreactivity). skbr3 as a her2/neu positive cell line was used ...

Both the protein used and the conjugation method are factors which may be relevant for targeting infection with 111In-labelled proteins. In this study, human immunoglobulin G (IgG), conjugated to either DTPA or LiLo, and LiLo conjugated human immunoglobulin M (IgM) were evaluated. In rats with Staphylococcus aureus calf muscle infection, biodistribution was determined 6, 24 and 48 h after the i...

The purpose of this study was to determine whether the Bcr-Abl tyrosine kinase can be assessed by gamma-imaging using an 111In-labeled anti-phosphotyrosine (APT) antibody, and if the response to treatment with imatinib could be detected using this imaging technique. APT antibody was labeled with 111In using ethylenedicysteine (EC) as a chelator. To determine if 111In-EC-APT could assess a nonre...

UNLABELLED Receptor-targeted scintigraphy and radionuclide therapy with radiolabeled somatostatin analogs are successfully applied for somatostatin receptor-positive tumors. The synergistic effects of an apoptosis-inducing factor, for example, the Arg-Gly-Asp (RGD) motif, can increase the radiotherapeutic efficacy of these peptides. Hence, the tumoricidal effects of the hybrid peptide RGD-dieth...

We investigated the generation of proton- and alpha-induced nuclear cross-section data in production Indium-111 (111In) for application medicine. Here, we are interested three reaction channels, which 109Ag (α, 2n), 111Cd (p, n) 112Cd 111In. A random forest algorithm was used to generate by using an experimental from Experimental Nuclear Reaction Data (EXFOR) database as input. Hence, reasonabl...

Immunoglobulin G (IgG) antibodies to carcinoembryonic antigen (CEA) were labelled with radioactive indium (111In) or iodine (131I) and a comparison made of their value in locating CEA producing tumours. Eleven patients given 111In-anti-CEA had 31 tumours as judged by a combination of all techniques. Of these, 28 were detected by 111In-anti-CEA and 26 by conventional clinical techniques. Five of...
