BACKGROUND The salutogenic model has been established as a health promoting resource that is related to a strong sense of coherence (SOC), positive subjective health and quality of life (QoL). The aim of the study was to compare internal and external resources, life style factors, perceived health and QoL in Japan and Austria and to determine associations among these factors. METHODOLOGY AND ...

Abstract. Bellman, Kalaba, and Lockett recently proposed a numerical method for inverting the Laplace transform. The method consists in first reducing the infinite interval of integration to a finite one by a preliminary substitution of variables, and then employing an n-point Gauss-Legendre quadrature formula to reduce the inversion problem (approximately) to that of solving a system of n line...

Quasi-elastic neutron scattering (QENS) spectra of heavy water solutions of γ-cyclodextrin (γ-CD), and of methylated derivatives of cyclodextrins, 2,6-di-O-methyl β-CD (DIMEB) and 2,3,6-tri-O-methyl-γ-CD (TRIMEG) were taken in the temperature range from 5 °C to 45 °C. The spectra were compared to a model for the scattering function S(Q, ω) describing translational and rotational dynamics of the...

Various heptasubstituted derivatives of β-cyclodextrin (β-CD) bearing 1, 2 and 3 methyl substituents per glucose unit were synthesized by regioselective methods. Binding free energies and binding enthalpies of these hosts towards 4-tert-butylbenzoate and adamantane-1-carboxylate were determined by isothermal titration microcalorimetry (ITC). It was found that methyl substituents at the secondar...

This paper describes the synthesis, structural characterization and cellular uptake of a supramolecular 1 : 2 inclusion complex of meso-tetraphenylporphyrin having an octaarginine peptide chain (R8-TPP) and heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin (TMe-β-CD). R8-TPP was synthesized by 2 approaches: (1) on-resin conjugation of the N-terminal of octaarginine with 5-(4-carboxyphenyl)-10,15,20-t...

DNA methylation as an epigenetic mediator plays the important role in spatial and temporal gene regulation and ensures the stability and the plasticity of organism. In this investigation, methylation sensitive amplification polymorphism (MSAP) were assessed in CCGG sites on a halophytic plant, Aeluropuslittoralis in response to different temperature stresses including freezing...
