Affibody molecules are small (-7 kDa) affinity proteins of non-immunoglobulin origin that have been generated to specifically interact with a large number of clinically important molecular targets. In this thesis, Affibody molecules have been employed as tracers for radionuclide molecular imaging of HER2and IGF-1R-expressing tumors, paper I-IV, and for surface knockdown of EGFR, paper V. In pap...
Secure determination of the binding of 99mTc-radiopharmaceuticals to plasma (P) and blood cell (BC) constituents can help to understand the biodistribution of radiophamaceuticals. The reported precipitation studies of blood with radiopharmaceuticals have shown that the results can not be easily compared between studies. We decided to determine the "gold standard" concentration of trichloroaceti...
Thiamazole inhibits the thyroid hormone synthesis and does not inactivate existing thyroxine triiodothyronine that circulate in blood. In this paper electrochemical behavior was monitored by cyclic voltammetry on glassy carbon (GC) electrode absence presence of sodium pertechnetate (99mTc). The influence different concentrations without radiopharmaceutical 99mTc, effect number scan cycles, 99mT...
Cerebral amyloid angiopathy (CAA) is characterized by the deposition of amyloid aggregates in the walls of the cerebral vasculature. Recently, the development of molecular imaging probes targeting CAA has been attracting much attention. We previously reported the 99mTc-hydroxamamide (99mTc-Ham) complex with a bivalent benzothiazole scaffold as a binding moiety for amyloid aggregates ([99mTc]BT2...
Introduction: The radioimmunoscintigraphy (RIS) has found widespread clinical applications in tumor diagnosis. Human epithelial mucin, MUC1, is commonly over expressed in adenocarcinoma including 80% of breast cancers and represents a useful target for RIS. The PR81 is a new murine anti-MUC1 monoclonal antibody that was found to react with the membrane extracts of se...
Novel synthetic methods for producing an array of chelates for use in "click"-radiolabeling of peptides are described, and their reactivity with regards to subsequent conjugation and radiolabeling is discussed.
These studies focused on a new radiolabeling technique with copper ((64)Cu) and zirconium ((89)Zr) for positron emission tomography (PET) imaging using a CD45 antibody. Synthesis of (64)Cu-CD45 and (89)Zr-CD45 immunoconjugates was performed and the evaluation of the potential toxicity of radiolabeling human peripheral blood stem cells (hPBSC) was assessed in vitro (viability, population doublin...
Background. Topical diagnosis of primary hyperparathyroidism (PHPT) remains an urgent problem due to the high incidence persistence and recurrence after surgical treatment. At preoperative stage, a search for parathyroid hormone hyperproduction source is performed using instrumental methods: ultrasound, scintigraphy glands (PTG) multislice computed tomography (MSCT). The cause PHPT parathyroide...
Purpose: To demonstrate a rare clinical case of early recurrence verified primary genital lymphoma and the possibility 99mTc-1-Thio-D-glucose (99mTc-TG) SPECT/CT using to brain metastasis diagnosis. Material methods: A patient with diagnosis diffuse large B-cell underwent magnetic resonance imaging (MRI) assess extent disease. Post-treatment follow-up included 18F-FDG PET/CT. diagnose metastasi...
BACKGROUND AND PURPOSE The brain distribution of 9mTc-hexamethylpropyleneamine oxime (HMPAO) correlates with regional brain perfusion, whereas 99mTc-ethyl cysteinate dimer (ECD) reflects not only perfusion but also the metabolic status of brain tissue. We compared 99mTc-ECD single-photon emission CT (SPECT) with 99mTc-HMPAO SPECT early after recanalization by local intraarterial thrombolysis (L...
