Item New approach to assessment of aging processes at the cellular level by NMR spectroscopy(Ośrodek Wydawnictw Naukowych Polish Academy of Sciences, 2000) Czapla, Zbigniew; Fojud, Zbigniew; Cieślik, Joachim; Jurga, StefanThe paper presents results of the proton relaxation time T1 measurements by 1H NMR for oral epithelium samples taken from 320 subjects, men and women, in different age, from 19 to 95 year old. The times of nuclear magnetic relaxation T1 were found to be correlated with the age of the subjects.Item The appraisal of the scope for the application of nuclear magnetic resonance (NMR) measurement methods for the estimation of the biological age in various stages of human ontogeny(Adam Mickiewicz University, Faculty of Biology, 1999) Czapla, Zbigniew; Fojud, ZbigniewThe main objective of the study is to find a new physical parameter meeting the criterion of the biological age estimation in various stages of human ontogeny, and thus to find a new research methodology for this field of research. For this purpose an NMR Bruker 200 MHz spectrometer was used. Two physical parameters: relaxation time (T1) and spectrum shape were determined. The research material was oral mucosa epithelium sampled in a group of young people of both sexes (31 subjects) and in a group of men (18 subjects). Relaxation time (T1) and spectrum shape were recorded for hydrogen nuclei (H1). The physical phenomena were analysed statistically (regression analysis) and their biological interpretation was attempted.Item Zastosowanie metod pomiarowych MRJ do określania wieku biologicznego w każdej fazie ontogenezy(Instytut Fizyki Jądrowej im. H. Niewodniczańskiego w Krakowie, 1998) Czapla, Zbigniew; Fojud, Zbigniew
