Badania bioaktywności z wykorzystaniem komórek kościotwórczych na tytanie pokrytym chitozanem = Bioactivity studies using osteogenic cells on titanium coated with chitosan
PublicationChitosan is a natural polymer from the group of polysaccharides, which has found wide application in biomedical applications to induce bioactivity of implant. The studies described were carried out test imposition of chitosan membranes with varying degrees of deacetylation on the surface of titanium, and then check the bioactivity of the material in vitro, using osteogenic cells MC3T3-E1. Titanium surface before imposition of...

Determination of estrogenic endocrine disruptors in environmental samples - a review of chromatographic methods
PublicationWśród związków endokrynnych to estrogeny zarówno naturalne jak i syntetyczne zostały wskazane i opisane jako związki niosące ze sobą największy potencjał aktywności estrogennej. Wysoki potencjał estrogenny jaki posiadają związki z grupy hormonów płciowych potwierdziły badania przeprowadzone zarówno in vitro jak i in vivo. W dużej części (50-95%) próbek ścieków pochodzących z oczyszczalni ścieków zostały wykryte związki z grupy...

Magnetic field effects in dye-sensitized solar cells controlled by different cell architecture
PublicationThe charge recombination and exciton dissociation are generally recognized as the basic electronic processes limiting the efficiency of photovoltaic devices. In this work, we propose a detailed mechanism of photocurrent generation in dye-sensitized solar cells (DSSCs) examined by magnetic field effect (MFE) technique. Here we demonstrate that the magnitude of the MFE on photocurrent in DSSCs can be controlled by the radius and...

Immune escape of B-cell lymphoblastic leukemic cells through a lineage switch to acute myeloid leukemia
PublicationAcute leukemia (AL) with a lineage switch (LS) is associated with poor prognosis. The predisposing factors of LS are unknown, apart from KMT2A rearrangements that have been reported to be associated with LS. Herein, we present two cases and review all 104 published cases to identify risk factors for LS. Most of the patients (75.5%) experienced a switch from the lymphoid phenotype to the myeloid phenotype. Eighteen patients (17.0%)...

Antitumour imidazoacridone C-1311 induces cell death by mitotic catastrophe in human colon carcinoma cells
PublicationW przedstawionych badaniach określano mechanizm śmierci komórkowej indukowanej przez imidazoakrydon C-1311 (Symadex) w komórkach HT-29 ludzkiego raka jelita grubego, które wykazywały szczególną wrażliwość na ten związek w eksperymentalnych modelach in vitro i in vivo. Przy stężeniu odpowiadającemu dawce IC99, związek powodował zahamowanie progresji cyklu komórkowej w fazie S po czym następował blok w fazie G2. Po czasach 48-96...

DNA structure and integrity checkpoints in the cell cycle and their role in drug targeting and resistance of tumor cells to anticancer treatment
PublicationW artykule dokonaliśmy przeglądu literatury dotyczącej różnych typów uszkodzeń DNA indukowanych przez różne czynniki terapeutyczne w komórkach nowotworowych. Omówiliśmy także w jaki sposób aktywują różne typy punktów kontrolnych w cyklu komórkowym i w jaki sposób punkty te są regulowane przez inne szlaki sygnalizacji wewnątrzkomórkowej takie jak szlaki naprawy uszkodzeń DNA, stresu komórkowego i śmierci-przeżycia. W szczególności...

Chromatographic analyses of Lavandula angustifolia and Rosmarinus officinalis extracts and their biological effects in mammalian cells and cell-free systems
PublicationKnowledge of biological properties of natural compounds allows to understand their therapeutic value, efficacy and security. We investigated: composition of Lavandula angustifolia (LA) and Rosmarinus officinalis (RO) extracts, their antioxidant capacity, cytotoxicity and genotoxicity, their DNA-protective potential against DNA damage induced in hamster V79 cells by several genotoxins or in plasmid DNA by Fe2+ ions and activity...

Dye-sensitized solar cells, in: Physics of Nanostructured Solar Cells
PublicationRozwój nanotechnologii otwiera coraz szersze horyzonty w dziedzinie zastosowania nowych materiałów w istniejących technologiach. Po tranzystorach także inne urządzenia wchodzą w erę nanotechnologii, w tym także te, dla których podstawowym materiałem są półprzewodniki i materiały organiczne. Ogniwa słoneczne nie są w tym zakresie wyjątkiem. W książce przedstawiono różne rodzaje ogniwa fotowoltaicznych i związane z ich eksploatacją...

Cell Density-Dependent Cytological Stage Profile and Its Application for a Screen of Cytostatic Agents Active Toward Leukemic Stem Cells
PublicationProliferation and expansion of leukemia is driven by leukemic stem cells (LSCs). Multidrug resistance (MDR) of LSCs is one of the main reasons of failure and relapses in acute myeloid leukemia (AML) treatment. In this study, we show that maintaining HL-60 at low cell culture density or applying a 240-day treatment with anthrapyridazone (BS-121) increased the percentage of primitive cells, which include LSCs determining the overall...

Increased susceptibility of PARP-1 KO cells to antitumor triazoloacridone C-1305 is associated with permanent G2 cell cycle arrest.
PublicationTriazoloakrydon C-1305 jest nowym inhibitorem topoizomerazy II wykazującym wysoką aktywność przeciwnowotworową. W tej pracy badaliśmy działanie cytotoksyczne pochodnej C-1305 i jej analogu strukturalnego C-1533 wobec komórek fibroblastów mysich i dwóch mutantów, w których uszkodzono gen PARP-1. Jak wykazaliśmy, komórki z uszkodzonym genem PARP-1 są nadwrażliwe na działanie związku C-1305 w porównaniu z komórkami PARP-1 +/+ podczas...

Triazoloacridone C-1305 abrogates the restriction checkpoint in cells lacking functional p53 and promotes their accumulation in the G2/M phase of the cell cycle
PublicationTriazoloakrydon C-1305, nowy inhibitor topoizomerazy II, wykazuje wysoką aktywość cytotoksyczną wobec komórek wielu typów nowotworów. Komórki mysie pozbawione genu PARP-1 wykazywały nadwrażliwość na działanie tego związku. W pracy testowaliśmy działanie związku wobec dwóch różnych komóek nowotworowych różniących się statusem p53: komórkami białaczki myelocytarnej HL-60 i raka sutka MCF-7. Wykazaliśmy, że inkubacja ze związkiem...

Improved cytotoxicity and preserved level of cell death induced in colon cancer cells by doxorubicin after its conjugation with iron-oxide magnetic nanoparticles
PublicationA promising strategy for overcoming the problem of limited efficacy in antitumor drug delivery and in drug release is the use of a nanoparticle-conjugated drug. Doxorubicin (Dox) anticancer chemotherapeutics has been widely studied in this respect, because of severe cardiotoxic side effects. Here, we investigated the cytotoxic effects, the uptake process, the changes in cell cycle progression and the cell death processes in the...
