From chemoresistance to cancer stem cells: the case of BRCP/ABCG2 half transporter
PublikacjaLudzkie białko ABCG2 jest pompą typu ABC tworzącą homodimery i aktywnie transportującą leki i inne substraty naturalne i syntetyczne. Nadekspresja tego białko prowadzi do oporności na leki przeciwnowotworowe. Białko ABCG2 występuje w wielu formach zmutowanych, różniących się własnościami substratowymi, stąd istotne dla oporności na leki jest jaka forma genu i białka ABCG2 ulega nadekspresji w komórce. Ostatnie badania wskazują,...

Caffeine Inhibits Differentiation Of Lung Cancer Stem Cells By Modulating Their Respiratory Metabolism
PublikacjaIt is ell established that many tumor types contain a fraction of cells, with stem cell-like properties, called cancer stem cells (CSCs), that are resistant to apoptosis induced by therapeutic agents. The presence of CSCs may explain why a standard anticancer treatment, that eliminates only differentiated cancer cells, does not lead to cancer cure.We previously showed the existence of caffeine-sensitive mechanism that controls...

Sensorless induction motor drive with voltage inverter and sine-wave filter
PublikacjaThis paper presents a speed sensorless control system of an induction motor with an output LC filter. It is known that the parameters design of the filter gives sine wave motor supply voltage but complicates control and estimation process. The reason is that the voltage drop and phase shift between filter input and output signals are imposed, and hence the motor voltages and currents differ from the inverter output waveforms. To...
