    (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.
