Nuclear Magnetic Resonance (NMR) is widely used technique in cancer diagnosis and treatment planning. It is employed to search for the high concentration regions of particular metabolites, which are directly related to the concentration of cancer cells. NMR signal maybe be characterized by a set of peaks which are representation of every distinct metabolite. Area under peak must be calculated in order to obtain proper information about metabolite amount. Commercially available software allows for the analysis of one-peak-in-time only. The proposed technique, based on Gaussian Mixture Model (GMM), allows for modeling all-peaks-in-time, and corrects after the neighboring peaks giving more accurate estimates of metabolite concentration. The resulting software processes NMR signal from the very beginning up to the final result, which is given in a form of so called metabolite map.

Cholesterol is one of the more important compounds causing arteriosclerosis and other illnesses of the circulatory system. In this work we have developed a procedure for separating a mixture of sterols from commercial consumable fats and, as the next step, identifying the main components of the sterol mixture. The method of separation included conventional and over-pressure thin-layer chromatography and solid-phase extraction (SPE); capillary gas chromatography with mass spectrometric detection was the main method of identification. Sterols and sterol esters were separated from the fats by solid-phase extraction on Bakerbond aminopropyl or silica gel columns. Preli-minary identification of the isolated sterols was achieved by TLC in a DS-sandwich type chamber. Full identification of the isolated sterols was performed by GC-MS and quantitative estimation of the cholesterol content by capillary GC with flame ionization detection. The amount of sterols was found to be in the range 4.01-11.46 mg g-1 fat; the amount of cholesterol was 0-5.14 mg g-1 fat.
