The Aβ(16-22) sequence KLVFFAE spans the hydrophobic core of the Aβ peptide and plays an important role in its self-assembly. Apart from forming amyloid fibrils, Aβ(16-22) can self-associate into highly ordered nanotubes and ribbon-like structures depending on the composition of solvent used for dissolution. The Aβ(16-22) sequence which has FF at the 19th and 20th positions would be a good mode...

OBJECTIVE To evaluate the efficacy and the tolerability of viscosupplementation (VS) with hyaluronic acid (Hylan GF 20) in a cohort of 36 patients affected by hip osteoarthritis through a 18 months follow-up. METHODS Viscosupplementation was performed with an anteriorsagittal approach, under ultrasound guidance. 36 patients were administered hyaluronic acid intraarticularly in the hip, with a...

BACKGROUND Patients with schizophrenia have severe problems with personal and social relations which affect their quality of life. AIM The aim of the paper was to monitor personal and social relations in patients with schizophrenia and to find out the differences regarding socio-demographic characteristics and ambulatory and day hospital treatment. MATERIAL AND METHODS The investigation inc...

We analyse the evolution of emerging market loan spreads at a more disaggregated level than other current studies, providing statistical support to the assumption of the “speciality” of the international interbank market, to the extent that the pricing of interbank credit is insensitive to the nature (public or private) of the borrower. In sharp contrast, the public or private nature of other b...

This contribution reports solution-phase structural studies of oligomers of a family of peptides derived from the β-amyloid peptide (Aβ). We had previously reported the X-ray crystallographic structures of the oligomers and oligomer assemblies formed in the solid state by a macrocyclic β-sheet peptide containing the Aβ(15-23) nonapeptide. In the current study, we set out to determine its assemb...

Benzene, toluene, p-xylene, and [60]fullerene are shown to be weak ligands to a hard metal such as iron(III) in Fe(TPP)+ cation (TPP ) tetraphenylporphyrinate). X-ray crystal structures of [Fe(TPP)(C6H6)][CB11H6Br6]‚3.5C6H6 (1), [Fe(TPP)(C7H8)][CB11H6Cl6]‚2C7H8 (2), [Fe(TPP)(C8H10)][Ag(CB11H6Br6)2]‚ arene (3), and [Fe(TPP)(C60)][F20-BPh4]‚2.5dichlorobenzene (4) show distinctively short Fe‚‚‚C c...

FDI flows grew exponentially during the 1990s, experienced a sharp decline over the period 20012004, and have recently started to recover. The decline was mostly due to a fall in FDI flows within the OECD, particularly of FDI flows to continental Europe. In recent years, FDI flows to developing countries have also increased substantially. This trend has been encouraged by governments who view i...

This study investigates the relationship between globalization and income inequality by developing a new globalization index based on economic growth. In addition two other indices of globalization, non-parametric Kearney and parametric principal component analysis are used as benchmarks to compare the results. The proposed new index is decomposed into four sub components. The index is also est...

In a search for strains producing biocides with a wide spectrum of activity, a new strain was isolated. This strain was taxonomically characterized as Streptomyces rochei F20, and the chemical structure of the bioactive product extracted from its fermentation broth was determined to be a mixture of streptothricins. From a genomic library of the producer strain prepared in the heterologous host ...

The main goal of the study was to determine gender differences in validity scales of personality measuring instruments, among the psychiatric patients. Additional goals are to find the differences among male and female psychiatric patients, in relation to their age group, education level and type of psychiatric diagnosis. A total of 331 male and 331 female participants (psychiatric patients) ar...
