The aim of this article is to briefly present progress in the development of the potent adenosine receptor (AR) antagonists with high selectivity for either A1, A2A, or A2B ARs. The structural requirements for each AR subtype were discussed as well a

Copper(II) and nickel(II) complexes with selected N,N'-ethylenebis(1-phenyl-3-methyl-4-acylpyrazoloneimine) ligands were synthesised and characterised spectroscopically. Molar conductivity measurements for the complexes in DMF indxate that the comple

The cross-polarization/magic-angle-spinning (CP/MAS) 77SeNMR experiment of Ph-Se-Se-Ph affords two signal series with isotropic chemical shifts at δiso = 425 and 350. IGLO calculations allow to assign the 77Se signals and to predict the orientation

The inelastic behavior of materials is described most efficiently by unified models when their material functions are determined so that flow, hardening, creep etc. will be covered correctly. In this paper, the adaptation of a model is not confined t
