The structure of the human tRNA(Lys3) anticodon stem and loop domain (ASL(Lys3)) provides evidence of the physicochemical contributions of N6-threonylcarbamoyladenosine (t(6)A(37)) to tRNA(Lys3) functions. The t(6)A(37)-modified anticodon stem and loop domain of tRNA(Lys3)(UUU) (ASL(Lys3)(UUU)- t(6)A(37)) with a UUU anticodon is bound by the appropriately(More)
Nucleoside modifications are important to the structure of all tRNAs and are critical to the function of some tRNA species. The transcript of human tRNA(Lys3)(UUU) with a UUU anticodon, and the corresponding anticodon stem and loop domain (ASL(Lys3)(UUU)), are unable to bind to poly-A programmed ribosomes. To determine if specific anticodon domain modified(More)
Magnetic systems exhibiting an exchange bias effect are being considered as materials for applications in data storage devices, sensors, and biomedicine. Because the size of new magnetic devices is being continuously reduced, the influence of thermally induced instabilities in magnetic order has to be taken into account during their fabrication process. In(More)
Desorption electrospray ion source (DESI) is widely used as an MS imaging technique. It is a rapid and convenient method of surface analysis, but to date, there are methodological obstacles to its application to the analysis of cell culture. This study reported optimised conditions for the analysis of cell culture samples. Parameters such as the surface,(More)
The generation of nanoalloys of immiscible metals is still a challenge using conventional methods. However, because these materials are currently attracting much attention, alternative methods are needed. In this article, we demonstrate a simple but powerful strategy for the generation of a new metastable alloy of immiscible metals. Au(1-x)Ni(x) 3D(More)
Magnetic nanostructures revealing exchange bias effect have gained a lot of interest in recent years due to their possible applications in modern devices with various functionalities. In this paper, we present our studies on patterned [CoO/Co/Pd]10 multilayer where ferromagnetic material is in a form of clusters, instead of being a continuous layer. The(More)
1. Non-histone chromatin protein fractions NHCP1 and NHCP2 eluted from hydroxyapatite with 50 and 100 mM phosphate buffer (pH 6.8) from nuclei of Kirkman-Robbins hepatoma from 4th, 7th and 9th day of growth were analysed by one- and two-dimensional gel electrophoresis as well as Western blot technique in the presence of antibodies elicited against NHCP1,(More)
