Current progress in nanomedicine has exploited the possibility of designing tumor-targeted nanocarriers being able to deliver radionuclide payloads in a site or molecular selective manner to improve the efficacy and safety of cancer imaging and therapy. Radionuclides of auger electron-, alpha-, beta-, and gamma-radiation emitters have been(More)
Nanoliposomes are useful carriers in drug delivery. Radiolabeled nanoliposomes have potential applications in radiotherapy and diagnostic imaging. In this study, the biodistribution and pharmacokinetics of 188Re-BMEDA-labelled pegylated liposomes (RBLPL) and unencapsulated 188Re-BMEDA administered by the i.v. route in murine C26-colon tumour-bearing mice(More)
BACKGROUND Nanoliposomes are designed as carriers capable of packaging drugs through passive targeting tumor sites by enhanced permeability and retention (EPR) effects. In the present study the biodistribution, pharmacokinetics, micro single-photon emission computed tomography (micro-SPECT/CT) image, dosimetry, and therapeutic efficacy of (188)Re-labeled(More)
INTRODUCTION Trastuzumab (Herceptin), a humanized IgG1 monoclonal antibody directed against the extracellular domain of the HER2 protein, acts as an immunotherapeutic agent for HER2-overexpressing human breast cancers. Radiolabeled trastuzumab with beta- or alpha emitters can be used as radioimmunotherapeutic agent for the similar purpose but with(More)
OBJECTIVE The OLINDA/EXM computer code was created as a replacement for the widely used MIRDOSE3 code for radiation dosimetry in nuclear medicine. A dosimetric analysis with these codes was performed to evaluate nanoliposomes as carriers of radionuclides ((188)Re-liposomes) in colon carcinoma-bearing mice. METHODS Pharmacokinetic data for (188)Re-N, N-bis(More)
BACKGROUND The overexpression of Ck19 antigen occurs frequently in human carcinomas. The strategy and mechanism of radioimmunotherapy using Re-188-mAbCx-99 to Ck19 on human cervical carcinoma cells was investigated in this study. MATERIALS AND METHODS Using mAbCx-99, the overexpression of Ck19 protein in lysates of cell lines and tissues from various(More)
UNLABELLED Non-small cell lung cancer (NSCLC) is a highly morbid and mortal cancer type that is difficult to eradicate using conventional chemotherapy and radiotherapy. Little is known about whether radionuclide-based pharmaceuticals can be used for treating NSCLC. Here we embedded the therapeutic radionuclide (188)Re in PEGylated (PEG is polyethylene(More)
Fluorine-18 fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) imaging demonstrated the change of glucose consumption of tumor cells, but problems with specificity and difficulties in early detection of tumor response to chemotherapy have led to the development of new PET tracers. Fluorine-18-fluorothymidine ((18)F-FLT) images cellular(More)
BACKGROUND Recombinant human factor IX (rhFIX) is a 56 kDa glycoprotein with full biological activity providing a guarantee of freedom from blood-borne viral contamination in the therapy of hemophilia B, but no data are available on the distribution of transgenic pig-produced rhFIX post injection (p.i.). Therefore, an 131I-radiolabeled rhFIX was developed(More)
The pharmacokinetics and internal radionuclide therapy of intraperitoneally administrated (188)Re-N,N-bis(2-mercaptoethyl)-N',N'-diethylethylenediamine (BMEDA)-labeled pegylated liposomal doxorubicin ((188)Re-DXR-liposome) were investigated in the C26 murine colon carcinoma ascites mouse model. After intraperitoneal administration of the nanotargeted(More)
