The Fig. 4 legend is incorrect. The third sentence of the Fig. 4 legend should have been omitted. The complete, correct Fig. 4 legend is: Fig 2. Unusually rapid biodistribution of radiolabeled HRG. A. Blood kinetics of l-albumin, l-hHRG and l-mHRG in C57BL/6 mice. (n = 4/time point). B. Biodistribution of l-hHRG in selected C57BL/6 mouse organs. C. Percentage of radioactivity in blood plasma, a...

Non-invasive assessment of the biodistribution is of great importance during the development of new pharmaceutical compounds. In this contribution, the applicability of in ovo MRI for monitoring the biodistribution of MR contrast agent-labelled compounds was investigated in mamaria carcinomas xentotransplanted on the chorioallantoic membrane (CAM) exemplarily for Gd-DOTA and cHSA-PEO (2000)16-G...

Since the human genome decoding, understanding and identification of genetic disturbances behind many diseases, including cancer, are intensively increasing. Scientific and technological advances in this area trigger the search for therapeutic (curative) approaches targeting the correction of gene disturbances. Gene therapy medicinal products (GTMPs) emerge in this context, bringing new challen...

Drug delivery systems involve technology designed to maximize therapeutic efficacy of drugs by controlling their biodistribution profile. In order to optimize a function of the delivery systems, their biodistribution characteristics should be systematically understood. Pharmacokinetic analysis based on the clearance concepts provides quantitative information of the biodistribution, which can be...

Adeno-associated virus (AAV) mediated gene expression is a powerful tool for gene therapy and preclinical studies. A comprehensive analysis of CNS cell type tropism, expression levels and biodistribution of different capsid serotypes has not yet been undertaken in neonatal rodents. Our previous studies show that intracerebroventricular injection with AAV2/1 on neonatal day P0 results in widespr...

Affibody molecules constitute a class of small (7 kDa) scaffold proteins that can be engineered to have excellent tumor targeting properties. High reabsorption in kidneys complicates development of affibody molecules for radionuclide therapy. In this study, we evaluated the influence of the composition of cysteine-containing C-terminal peptide-based chelators on the biodistribution and renal re...

objectives: the aim of this research was the development of 111in-labeled porphyrins as possible radiopharmaceuticals for the imaging of tumors. methods: ligands, 5, 10, 15, 20-tetrakis (3, 5-dihydroxyphenyl) porphyrin) (tdhpp), 5, 10, 15, 20-tetrakis (4-hydroxyphenyl) porphyrin (thpp) and 5, 10, 15, 20-tetrakis (3,4-dimethoxyphenyl) porphyrin) (tdmpp) were labeled with 111incl3 (produced from ...

background: therapeutic radiopharmaceuticals are designed to deliver high doses of radiation to selected target organs with an aim of minimizing unwanted radiation to surrounding healthy tissue. due to the potential of targeted radiotherapy to treat a wide range of malignant conditions, [153sm]-samarium maltolate was developed for possible therapeutic applications. materials and methods: the or...
