W pracy dokonano analizy działania różnych modeli neuronowych do oceny suszu melona żółtego. Zastosowane modele różnią się między sobą architekturą sieci (liczbą neuronów w warstwie ukrytej). Ocenę jakości działania sieci dokonano na podstawie średnich błędów względnych. Do nauki sieci wykorzystano zależności między oceną sensoryczną suszu melona żółtego a wynikami badań reologicznych i mechanicznych oraz sposobem suszenia i obróbki wstępnej materiału badawczego. Na podstawie uzyskanych wyników stwierdzono, że wykorzystanie SSN pozwoli ograniczyć badania sensoryczne i zastąpić je analizą instrumentalną.

Structures analogous to Drosophila spectrosomes were found in mammalian lymphocytes. Repasky and colleagues discovered an intracellular spectrin-rich structure in lymphoid cells, which had far-reaching parallels with the fusome/spectrosome of D. melanogaster germ cells. This fact implies that spectrosomes may be characteristic not only of insect germ cells, but also that an analogous structure may play an important role in other cell types. The term “spectrosome” was first used by Lin and Spradling in 1995 to describe a large sphere of fusomal material in D. melanogaster germline stem cells and their differentiated daughter cells - cytoblasts. In the D. melanogaster ovary, membrane skeletal proteins such as ankyrin, α/β spectrin as well as adducin-like Hts protein(s) were found in this specific organelle - spectrosome/fusome. These organelles are involved in the creation of mitotic spindles and D. melanogaster cyst formation and oocyte differentiation, but the role of analogous spectrin based aggregates found in nucleated cells still remains unclear.

The aim of this investigation was to evaluate the changes in PAF concentrations in the plasma, PBMC and BMMC of patients with acute lymphoblastic leukemia (ALL) and acute myeloblastic leukemia (AML). The plasma was from 23 healthy volunteers (HV) and 44 patients with AL (16 ALL, 28 AML). The PBMC were from 15 HV and 55 patients with AL (18 ALL, 37 AML), and the BMMC from 40 patients with AL (11 ALL, 29 AML). Methanol-chloroform phospholipid extraction from 60 × 106 cells (PBMC or BMMC) was performed according to a modified version of Folch’s method. 31P MRS data was obtained on an AMX 300 Bruker spectrometer (7.05 T). The PAF concentration in the plasma of the patients with ALL or AML was lower than that for the healthy volunteers. The PAF concentration in the plasma of the patients with ALL did not differ significantly from that of the patients with AML. In the case of both the PBMC and BMMC, the PAF concentration was significantly diminished in patients with ALL relative to the concentration for those with AML and for the healthy volunteers. No differences were observed in the PAF concentrations for the AML patients and the healthy volunteers.

The aim of this study was to evaluate the phospholipid concentration in acute leukemia (AL) blast cells from peripheral blood (PBMC) and bone marrow (BMMC). In vitro 31P Nuclear Magnetic Resonance Spectroscopy (31P MRS) was used. The integral intensities of the resonant peaks and the phospholipid concentrations in PBMC and BMMC were analyzed. Differences in the phospholipid concentrations in cells from myeloblastic or lymphoblastic lines were also evaluated. This investigation was carried out on phospholipid extracts from PBMC and BMMC from 15 healthy volunteers and 77 patients with AL (samples taken at the moment of diagnosis). A significant decrease in sphingomyelin (SM) and phosphtidylserine (PS) was observed in the PBMC of patients with AL relative to the results for the healthy volunteers. For ALL, we found a significant decrease in the concentration of phosphatidylcholine plasmalogen (CPLAS), SM, PI+PE (phosphatidylinositol + phosphatidylethanolamine) and PS in comparison with the results for healthy volunteers and patients with AML. Experiments with BMMC cells revealed a significant decrease in the concentration of CPLAS, SM, PI+PE, and PS in ALL relative to AML. Additionally, a significant decrease in phosphatidylcholine (PC) concentration was observed in ALL compared to AML. If the phospholipid extracts were taken simultaneously from the same patient, there were no significant differences in the integral intensities and phospholipid concentrations between PBMC and BMMC.
