Modeling the electrical characteristics of P3HT:PCBM bulk heterojunction solar cells: Influence of the interface recombination
PublicationThe interface recombination of charge carriers located in the material with lower permittivity (Szmytkowski 2009 Chem.Phys.Lett. 470 123) has been implemented for the first time to calculate the electrical characteristics of the donor-acceptor P3HT:PCBM bulk heterojunction solar cell. In order to estimate the photocurrent density in this system, a simple analytical formula has been derived. We have obtained a very good agreement...

Tetrahydroquinolinone derivatives exert antiproliferative effect on lung cancer cells through apoptosis induction
PublicationThe anticancer properties of quinolones is a topic of interest among researchers in the scientific world. Because these compounds do not cause side effects, unlike the commonly used cytostatics, they are considered a promising source of new anticancer drugs. In this work, we designed a brief synthetic pathway and obtained a series of novel 8-phenyltetrahydroquinolinone derivatives functionalized with benzyl-type moieties at position...

Antibacterial Activity and Cytocompatibility of Bone Cement Enriched with Antibiotic, Nanosilver, and Nanocopper for Bone Regeneration
PublicationBacterial infections due to bone replacement surgeries require modifications of bone cement with antibacterial components. This study aimed to investigate whether the incorporation of gentamicin or nanometals into bone cement may reduce and to what extent bacterial growth without the loss of overall cytocompatibility and adverse effects in vitro. The bone cement Cemex was used as the base material, modified either with gentamicin...

Derivatives of 1-nitroacridine induce apoptosis only in a limited number of human colon adenocarcinoma cells
PublicationPraca dotyczy indukcji apoptozy w komórkach ludzkich raków okrężnicy HT29 i HCT8 pod wpływem pochodnych 1-nitroakrydyny: C-857 i C-1748. Wykazano, że związki te w stężeniach biologicznie istotnych (EC90) indukują apoptozę tylko w części populacji komórek. Efekt ten uzależniony był od czasu inkubacji komórek ze związkiem, a nie zależał od stężenia związku.

Imidazoacridinone C-1311 induces both autophagy and senescence in human lung cancer A549 cells
PublicationNiedrobnokomórkowy rak płuc (ang. NSCLC, non-small cell lung cancer), stanowiący blisko 80-87% wszystkich przypadków, jest najczęściej występującą formą raka płuc. Skuteczność dotychczas stosowanych chemoterapeutyków w stosunku do tej formy raka jest bardzo ograniczona dlatego poszukuje się nowych związków o lepszych właściwościach leczniczych. Imidazoakrydon C-1311 wykazuje wysoką aktywność cytotoksyczną wobec komórek niedrobnokomórkowego...
