The capabilities and applicability of the radiotracer technique for methodological studies in hydride generation and electrothermal atomic absorption spectrometry are discussed and demonstrated by using several selected examples. It is shown that, for studying chemical and physico-chemical aspects of atomic absorption spectrometric methods, the radiotracer technique is superior to other techniq...

Bone scintigraphy is an important diagnostic tool in the evaluation of skeletal pathologic conditions. However, the extraskeletal uptake of bone-seeking radiotracers is still an unexpected finding in most cases. We present a 5-year-old male with an unexpected focal accumulation of the radiotracer in the small bowel. Bowel accumulation of bone-seeking radiopharmaceuticals has been seen previousl...

A method is described in which anti-2-acetylaminofluorene immunoglobulins may be detected using a simple and sensitive screening procedure. The method is based on immunoglobulin binding of an 125I derivatized 2-aminofluorene radiotracer. Tracer binding is not isotype specific, and thus the method is useful for the detection of either IgG or IgA. Competitive binding experiments with the radiotra...

Abstract The chemical separation of zirconium from lanthanides by liquid–liquid extraction is challenging but critical for medical and technological applications. Using the example 89 Zr, we optimize liquid–liquid-extraction process means radiotracer technique. We produced Zr proton irradiation a metallic yttrium target at cyclotron. purification radionuclide was performed UTEVA resin. separate...

Peripheral vascular disease (PVD) is an atherosclerotic disease affecting the lower extremities, resulting in skeletal muscle ischemia, intermittent claudication, and, in more severe stages of disease, limb amputation and death. The evaluation of therapy in this patient population can be challenging, as the standard clinical indices are insensitive to assessment of regional alterations in skele...

Monoamine oxidase (MAO) oxidizes amines from both endogenous and exogenous sources thereby regulating the concentration of neurotransmitter amines such as serotonin, norepinephrine, and dopamine as well as many xenobiotics. MAO inhibitor drugs are used in the treatment of Parkinson's disease and in depression stimulating the development of radiotracer tools to probe the role of MAO in normal hu...

introduction: sentinel node mapping has been used for laryngeal carcinoma in several studies, with excellent results thus far.in the current study, we report our preliminary results on sentinel node mapping in laryngeal carcinoma using intra-operative peri-tumoral injection of a radiotracer.   materials and methods: patients with biopsy-proven squamous cell carcinoma of the larynx were included...

Monoamine oxidase (MAO) is an integral protein of outer mitochondrial membranes and occurs in neuronal and nonneuronal cells in the brain and in peripheral organs. It oxidizes amines from both endogenous and exogenous sources, thereby influencing the concentration of neurotransmitter amines as well as many xenobiotics. It occurs in two subtypes, MAO A and MAO B, which are different gene product...
