PURPOSE A specially designed self-expandable covered metallic stent impregnated with the beta-emitting radioisotope 166Ho (166Ho, energy: 1.85 and 1.76 MeV, T12: 26.8 h) was developed at our institute for the purpose of intraluminal palliative brachytherapy, as well as for treating malignant esophageal stricture and swallowing difficulty. The aim of this(More)
Intratumoural injection of an unsealed beta-emitting radionuclide is a new technique for the local control of tumours that has the advantage of delivering a higher radiation dose to tumour while minimising radiation hazard to the surrounding normal tissues. In this study, therapeutic effect, morphological alterations and biological responses to the(More)
Accurate and rapid diagnosis of Pandemic Influenza A/H1N1 2009 virus (H1N1 2009) infection is important for the prevention and control of influenza epidemics and the timely initiation of antiviral treatment. This study was conducted to evaluate the performance of several diagnostic tools for the detection of H1N1 2009. Flocked nasopharyngeal swabs were(More)
PURPOSE Holmium-166 ((166)Ho) is a neutron-activated radioactive isotope whose effectiveness in hepatocellular carcinoma (HCC) was first reported in a preclinical study in 1991. Chitosan is a polymer of 2-deoxy-2-amino-D-glucose that readily forms a chelate with heavy metals and converts from a solution under acidic conditions into a gel under neutral or(More)
BACKGROUND Iron overload is a predictable and life-threatening complication in patients dependent on the regular transfusion of RBCs. The aims of this study were to investigate the efficacy and safety of deferiprone in a variety of pediatric hematologic and/or oncologic patients with a high iron overload. METHODS SEVENTEEN PATIENTS (AGE: 1.1-20.4 years;(More)
PURPOSE A specially designed self-expandable covered metallic stent incorporated with beta-emitting radioisotope, Holmium-166 (Ho-166), was developed for delivering intraluminal brachytherapy as well as for internal bile drainage in malignant biliary stricture. The purpose of the study was to demonstrate the safety and tissue response of the radioactive(More)
99mTc-labeled 1-thio-beta-D-glucose (99mTc-1-TG) was synthesized under different ligand concentrations. 1-Thio-beta-D-glucose (1-TG) showed different chemical properties and higher stability at acid pH as compared to neutral and basic pH. Under different ligand concentrations, 99mTc-1-TG was obtained with high labeling efficiency of >97%, but the HPLC(More)
A series of novel 1,3,5-tris-azobenzenes were prepared from 1,3,5-trihalobenzene via Pd-catalyzed couplings of N-Boc aryl hydrazines and subsequent Cu(I)-mediated direct oxidations. The oxidation of tris-arylhydrazide provided the azobenzene as a mixture of all four of the possible E/Z-isomers; [E,E,E]-, [E,E,Z]-, [E,Z,Z]-, and(More)
A simple procedure was developed for coating the surface of a conventional percutaneous transluminal coronary angioplasty balloon angioplasty catheter with 166Ho. The absorbed dose delivered by the surface-coated catheter is twice that of a similar catheter filled with a solution containing the same activity of 166Ho. Leakage tests show that <0.6% of the(More)
