(Wydawnictwo Uniwersytetu Rzeszowskiego, 2020) Bober, Zuzanna; Galiniak, Sabina; Leksa, Dawid; Dynarowicz, Klaudia; Aebisher, David; Ostańska, Elżbieta; Czmil, Anna; Bar, Piotr; Bartusik-Aebisher, Dorota; Tutka, Piotr
Introduction. Cytisine, Cytisinum (C11H14N2O), is an organic chemical compound. Cytisine is heterotricyclic compound that is the toxic principle in Laburnum seeds and is found in many members of the Fabaceae (legume, pea or bean) family. Aim. The aim of the study is to measure the influence of water on the form of drug in the magnetic field 1.5 Tesla. Material and methods. For this purpose, magnetic resonance imaging tests were performed to check the solubility of pure cytisine, Desmoxan tablets and Tabex capsules. Results. From a pharmacological point of view, both Desmoxan tablets and Tabex capsules should exert the same effect on the human body, this is due to the identical content of the active substance, in this case cytisine (1.5 mg). Conclusion. The differences in the results obtained may be related to additional excipients that contain medications, but it is believed that they should not have a negative impact on the action of the active substance.
Lycopene activity on lung and kidney cancer cells by T2 relaxation time 1H Magnetic Resonance Imaging in vitro
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2020) Pogoda, Katarzyna; Pucka, Maria; Tabarkiewicz, Jacek; Bober, Zuzanna; Aebisher, David; Galiniak, Sabina; Bartusik-Aebisher, Dorota
Introduction. The paper presents the results of a study of cell cultures of lung cancer and kidney cancer using lycopene performed using clinical magnetic resonance imaging. Aim. The aim of the study was to evaluate lycopene activity on tumor cell cultures. Material and methods. For this purpose, MR tests were performed using the technique of determining transverse relaxation. Results. Described here studies demonstrated that lycopene may inhibit the growth of A549 and ACHN cell lines. Conclusion. We determine changes in spin lattice relaxavity T2 to monitor treatment of lung cancer cell line A549 and kidney cancer cell line ACHN cells treatment with lycopene.
Radio Frequency MRI coils
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2020) Truszkiewicz, Adrian; Aebisher, David; Bober, Zuzanna; Ożóg, Łukasz; Bartusik-Aebisher, Dorota
Introduction. Magnetic Resonance Imaging (MRI) coils technology is a powerful improvement for clinical diagnostics. This includes opportunities for mathematical and physical research into coil design. Aim. Here we present the method applied to MRI coil array designs. Material and methods. Analysis of literature and self-research. Results. The coils that emit the radiofrequency pulses are designed similarly. As much as possible, they deliver the same strength of radiofrequency to all voxels within their imaging volume. Surface coils on the other hand are usually not embedded in cylindrical surfaces relatively close to the surface of the body. Conclusion. The presented here results relates to the art of magnetic resonance imaging (MRI) and RF coils design. It finds particular application of RF coils in conjunction with bore type MRI scanners.
The potential of intracellular 13C MR spectroscopy to study the absolute configuration of endogenous and polarized alanine
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2020) Leksa, Natalia; Pękala, Anna; Pardak, Piotr; Dziedzic, Rafał; Bartusik-Aebisher, Dorota; Filip, Rafał; Galiniak, Sabina; Aebisher, David
Introduction. Quantitative and accurate monitoring of tumor makes hyperpolarized carbon (13C) Magnetic Resonance Imaging and Spectroscopy (MRI/S) a powerful tool for in vivo metabolic and structural study. Moreover, the studies of the properties and functions in tumor tissue of the compounds of carbon (C) that are organic, are fundamental to tumor biochemistry. Aim. To review 13C MR spectroscopy to study the absolute configuration of endogenous and polarized alanine Material and methods. An analysis of literature regarding 13C MR spectroscopy of polarized alanine. Results. Current evidence suggests that the determination of absolute configurations of amino acids play significant role in physiological mechanisms during tumor growth and treatment. Conclusions. Nearly 50% nuclear polarization for 13C can be achieved in various organic molecules when Dynamic Nuclear Polarization DNP is performed in a strong magnetic field and at cryogenic temperatures.
The role of MRI in the central nervous system
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2020) Leksa, Natalia; Aebisher, David; Bartusik-Aebisher, Dorota
Introduction. Magnetic Resonance Imaging (MRI) has modified the practice of radiology. MRI is base on safe interaction between radiowaves at a particular frequency and hydrogen nuclei in the body. Metabolic encephalophaties are by definition those disorder of the central nervous system that are not due primarily to structural abnormalities. Aim. Here we present the 1H MRI and functional MRI (fMRI) method applied to diagnosis of disorders of the central nervous system. Material and methods. Analysis of literature and self-research. Results.We have discussed the major MRI applications in the characteristic of the central nervous system. The relationship beteen the motion of flowing blood and the representation of the blood on images is complex. This work is an introduction to the basic ideas and techniques of fMRI. Therefore, both, 1H MRI and functional MRI, methods are ued in neuroscience. Conclusion. Nonivasive MRI and functional MRI are daily diagnostics methods in neurology.
Treating kidney cancer – a review
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2020) Przyczyna, Piotr; Aebisher, David; Bartusik-Aebisher, Dorota; Kaznowska, Ewa
Introduction. Kidney cancer in the structure of registered cases was in 6th place in men and 8th in women. Aim. Understanding the molecular biology of renal cell carcinoma has made it possible to produce new diagnostic methods. Material and methods. This review was performed according to a systematic literature search. Results. Minimally invasive techniques seem to have a bright future in kidney cancer. However, they still require many clinical trials before they enter the general clinical use. Conclusion. Photodynamic therapy, thanks to research conducted in kidney cancer, will find application in cancer of other organs.
