Dual inhibition of PI3K/Akt signaling and the DNA damage checkpoint in p53-deficient cells with strong survival signaling: implications for cancer therapy
PublicationOporność komórek nowotworowych na leki uszkadzjące DNA związana jest ściśle ze zdolnością do utrzymywania blok z fazie G2 cyklu komórkowego. Blok ten regulowany jest przez mechanizmy punktu kontrolnego G2/M oraz szlaki przeżycia komórkowego. W pracy badaliśmy rolę szlaku kinazy PI3K/Akt w funkcjonowaniu punktu kontrolnego cyklu komórkowego i wpływ na przeżycie komórek traktowanych lekiem przeciwnowotworowym - cisplatyną. Nasze...

Cancer stem cells and escape from drug-induced premature senescence in human lung tumor cells: implications for drug resistance and in vitro drug screening models
PublicationBadania z użyciem modelu komórek nowotworu płuc A549 wykazały, że komórki te po traktowaniu lekami uszkadzającymi DNA zatrzymują proliferację i wchodzą w stan starzenia komórkowego. Jednak post-inkubacja tych komórek prowadzi do powrotu do stanu proliferacji małej frakcji komórek. Wykazaliśy, że frakcja ta związana jest z obecnością komórek pierwotnych nowotworu w populacji komórek A549. Powrót do stanu proliferacji komóek A549...

A mechanistically approached review upon assorted cell lines stimulated by athermal electromagnetic irradiation
PublicationThe probable influence of electromagnetic irradiation on cancer treatment has been deduced from the interaction of artificial electromagnetic emissions with biological organisms. Nonetheless, the suspected health effects induced by electromagnetic-based technology imply that such a treatment may contaminate the adjacent healthy cells. Thus, gaining mechanistic insights into the problem is required to avoid athermal health hazards....

Design Analysis of Micro Gas Turbines in Closed Cycles
PublicationThe problems faced by designers of micro-turbines are connected with a very small volume flow rate of working media which leads to small blades’ height and high rotor speed. In the case of gas turbines this limitation can be overcome by the application of a closed cycle with very low pressure at the compressor inlet (lower than atmospheric pressure). In this way we may apply a micro gas turbine unit of accepted efficiency to work...

Gradient versus proper gradient homotopies
PublicationWe compare the sets of homotopy classes of gradient and proper gradient vector fields in the plane. Namely, we show that gradient and proper gradient homotopy classi cations are essentially different. We provide a complete description of the sets of homotopy classes of gradient maps from R^n to R^n and proper gradient maps from R^2 to R^2 with the Brouwer degree greater or equal to zero.

Using water sources extent during inundation as a reliable predictor for vegetation zonation in a natural wetland floodplain
PublicationDistinctive zones of inundation water during floods were shown to originate from different sources in some major floodplains around the world. Recent research showed that the zonation of water in rivers and floodplains is related to vegetation patterns. In spite of this, water source zones were not used for vegetation modeling due to difficulties in their delineation. In this study, we used simulation results of a fully-coupled...
