Processing of 1-nitroacridine-induced DNA-DNA cross-links by topoisomerase I is associated with enhanced cellular survival: a possible role of topoisomerase I in the removal of DNA cross-links
PublicationW tej pracy wykazujemy, że modyfikacje plazmidu indukowane przez wzrastające dawki 1-nitroakrydyn (nitracrine i związek C-857) prowadzą do zahamowania aktywności katalitycznej topoizomerazy I. Hamowanie to związane jest z pojawieniem się pojedynczoniciowych uszkodzeń DNA i tworzeniem kowalencyjnych kompleksów topoizomeraza I-DNA. Nie obserwowano takich efektów dla topoizomerazy typu II.Dalsze badania wykazały, że jedna z 1-nitroakrydyn...

Acceleration of the discrete Green's function computations
PublicationResults of the acceleration of the 3-D discrete Green's function (DGF) computations on the multicore processor are presented. The code was developed in the multiple precision arithmetic with use of the OpenMP parallel programming interface. As a result, the speedup factor of three orders of magnitude compared to the previous implementation was obtained thus applicability of the DGF in FDTD simulations was significantly improved.
