Treatment of larvae with F. oxysporum led to increase in apoLp-III level in the hemolymph and hemocytes, oppo- site to the level in fat body. In the non-denaturating electrophoresis immunoblots of challenged larvae hemolymph additional protein band ap- peared. This band was stronger both 15 and 60 min after immunization, suggesting that during immune response apoLp-III forms complexes with some molecules. All of these results suggest that type of pathogen and ex- position time on it, affect distribution of apoLp-III in in- sect body. Because of the fact that there are significant similarities between the role of mammalian apolipoproteins and in- sect apolipophorins in innate immune response, we hope our results obtained on the insect model will contribute to broadening the knowledge about functioning of apoE in mammalian immunity.

P2.77 Comparison of methods filtering signal from magnetic resonance spectroscopy Michał Staniszewski, Andrzej Polański Faculty of Automatic, Electronics, and Informatics, Silesian University of Technology, Gliwice, Poland e-mail: Michał Staniszewski <[email protected]> Nuclear magnetic resonance is used as a physical back- ground for magnetic resonance spectroscopy (MRS) and magnetic resonance imaging (MRI). Both methods are cur- rently useful in medicine to investigate a number of hu- man's diseases including cancer in brain, breast and prostate. While MRI can give specific knowledge about localization of investigated tissue, MRS on the other hand gives scien- tists biochemical information about researched tissues and tells how aggresive tumour can be. Signal detected in MRS is exposed to radio frequency pulse and transformed into a spectrum. Several impovements are necessary in order to use results of MRS as diagnostic tool. Few limitations of measurement such as low concentration of metabolites and limited time of observation can cause low signal to noise coefficient. However, after measurement methods called pre-processing techniques are used for enhancement. One of the pre-processing technique depends on noise which is present after measurement. Currently there are many meth- ods which lead to filter signal including implementation of time domain filters or basing on correctly identified model, namely Cadzow method. Presentation consists of descrip- tion of filtering methods and comparison of results. Acknowledgements The work was supported by "DoktoRIS - Program stypendialny na rzecz innowacyjnego Śląska".
