Chronic pain is an undertreated epidemic affecting quality of life in at least 20% the global population, and CNS-related side effects, tolerance, addiction are common features current medications. ?-Conotoxin Vc1.1 potently elicits prolonged analgesia preclinical chronic constriction injury visceral hypersensitivity models neuropathic pain. A backbone-cyclized variant, cVc1.1, exhibits superio...

Liposome-encapsulated hemoglobin (LEH) is an erythrocyte substitute that is a potential resuscitative fluid for the in vivo delivery of oxygen. We have noninvasively imaged radiolabeled LEH in vivo with technetium-99m (99mTc) to study the biodistribution in an anesthetized rabbit. Rabbits (2.5 kg, n = 8) were infused with 30 ml of LEH (200 mg of phospholipid, 2.5 g of hemoglobin per kg of body ...

BACKGROUND Overexpression of the gastrin-releasing peptide receptor (GRP-R) has been documented in several human neoplasms such as breast, prostate, and ovarian cancer. There is growing interest in developing radiolabeled peptide-based ligands toward these receptors for the purpose of in vivo imaging and radionuclide therapy of GRP-R-overexpressing tumors. A number of different peptide sequence...

INTRODUCTION Proof of concept for local gene therapy for the treatment of arthritis with immunomodulatory cytokine interferon beta (IFN-β) has shown promising results in animal models of rheumatoid arthritis (RA). For the treatment of RA patients, we engineered a recombinant adeno-associated serotype 5 vector (rAAV5) encoding human (h)IFN-β under control of a nuclear factor κB promoter (ART-I02...

PR81 is a monoclonal antibody that binds with high affinity to MUC1 that over expressed on breast tumors. PR81 is considered a suitable targeting molecule that was radiolabeled using Cu-64 for positron imaging studies. The monoclonal antibody was conjugated with DOTA moiety and after purification was evaluated for radiochemical purity, immunoreactivity, cell toxicity and structure integrity as ...

introduction: various bone palliative therapeutic agents have been developed and widely used for bone metastasis such as 153sm-edtmp. in this study, production, quality control and biodistribution studies of a newly developed therapeutic compound have been presented followed by imaging studies in wild-type rodents. methods: 153sm-tthmp was prepared starting from 153sm-smcl3, prepared by neutro...

The goal of the present investigation was to develop a physiologically based kinetic model to describe the biodistribution of immunologically active effector cells in normal and neoplastic tissues of mammals based on the current understanding of lymphocyte trafficking pathways and signals. The model was used to extrapolate biodistribution among different animal species and to identify differenc...

Objective(s): The objectives of this work was to assess the benefits of the application of Physiologically Based Pharmacokinetic (PBPK) models in patients with different neuroendocrine tumours (NET) who were treatedwith Lu-177 DOTATATE. The model utilises clinical data on biodistribution of radiolabeled peptides (RLPs) obtained by whole body scintigraphy (WBS) of the patients.Methods: The blood...

Introduction: In this research, [166Ho]Holmium chitosan complex production is described in details, followed by determination of complex radiochemical purity, stability and biodistribution (after intra-articular injection) in wild-type male rats. Finally a Ho-166 based chitosan kit for ultimate radiosynovectomy as well as radiotherapy applications was developed. Methods: 166</s...
