Opis:
Due to the questions concerning the Silesian autonomy it seems important to estimate whether and to what extend Silesians constitute a national minority. National minorities differ in terms of culture, language, religion, as well as in the sphere of economy. Analyses of the records of the year 2002 allow to confirm the existence of such differences of the people declaring Silesian nationality. It can be seen on the job market, not only in comparison with the inhabitants of other parts of Poland, but also in the Silesian and the Opole voyevodship.

Opis:
Members of the Obg subfamily of small GTP-binding proteins (called Obg, CgtA, ObgE or YhbZ in different bacterial species) have been found in various prokaryotic and eukaryotic organisms, ranging from bacteria to humans. Although serious changes in phenotypes are observed in mutant bacteria devoid of Obg or its homologues, specific roles of these GTP-binding proteins remain largely unknown. Recent genetic and biochemical studies, as well as determination of the structures of Obg proteins from Bacillus subtilis and Thermus thermophilus, shed new light on the possible functions of the members of the Obg subfamily and may constitute a starting point for the elucidation of their exact biological role.

Opis:
Although it is estimated that 20-30% of the general human population are carriers of Staphylococcus aureus, this bacterium is one of the most important etiological agents responsible for healthcare-associated infections. The appearance of methicillin resistant S. aureus (MRSA) strains has created serious therapeutical problems. Detailed understanding of the mechanisms of S. aureus infections seems necessary to develop new effective therapies against this pathogen. In this article, we present an overview of the biochemical and genetic mechanisms of pathogenicity of S. aureus strains. Virulence factors, organization of the genome and regulation of expression of genes involved in virulence, and mechanisms leading to methicilin resistance are presented and briefly discussed.

Opis:
In the period of open work markets in the European Union, and frequent migrations caused by search for employment it seems important to pay attention to experience gained due to the arrival of workers to the Upper Silesian work market as well as its results in the economic and social sphere. No state activity is able to defend the country from their consequences if so called "migration capacity" of the local community has expired. This "migratin capacity" of the local community defines the possibilities of the acceptance of assimilation of the newcomers without any social tensions as well as negative results in the eonomic and social sphere.

Opis:
Education stops being an autotelic value, growing from natural cognitive needs, from natural cognitive needs, from a desire to understand oneself, as well as the surrounding word better; instead, it becomes a certificate giving definite rights. In search of specific requirements we lose the ability at things; we lose the ability of e.g. independent thinking, intellectual openness. The process of introducing parameters to education also leads to various consequences contradictory to the idea of increasing its quality; this is connected with the general conviction about the low intellectual level of people starting university education, and in consequence, receiving university diplomas.

Opis:
The SeqA protein of Escherichia coli is not only the main negative regulator of DNA replication initiation but also a specific transcription factor. It binds to hemimethylated GATC sequences and, with somewhat different specificity, to fully methylated GATC regions. Recently, a microarray analysis was reported, in which transcriptomes of wild-type and ΔseqA strains were compared. Although in the seqA mutant the levels of some transcripts were significantly decreased while certain transcripts were evidently more abundant relative to wild-type bacteria, no correlation between the presence of GATC motifs in promoter sequences and transcription activity was found. However, here we show that when larger DNA fragments, encompassing positions from -250 to +250 relative to the transcription start site, are analyzed, some common features of GATC distribution near the promoters activated by SeqA can be demonstrated. Nevertheless, it seems that the GATC pattern is not the only determinant of SeqA-dependence of promoter activity.

Opis:
Previously performed experiments showed that methylxanthines, especially caffeine, may protect cells against cytostatic or cytotoxic effects of several aromatic compounds. One of the proposed mechanisms of this protection is based on stacking interactions between π electron systems of polycyclic aromatic molecules. In this work, we demonstrate that caffeine and other methylxanthines - pentoxifylline and theophylline - significantly decrease mutagenicity of the anticancer aromatic drugs daunomycin, doxorubicin and mitoxantrone. The spectrophotometric titration of these aromatic compounds by methylxanthines indicated formation of mixed aggregates. The concentrations of free active forms of the drugs decreased when the concentrations of methylxanthines increased in the mixture. Therefore, likely methylxanthines may play a role of scavengers of the free active forms of daunomycin, doxorubicin and mitoxantrone.

Opis:
Recent clinical research has pointed at hyperhomocysteinemia as an independent risk factor in a number of cardiovascular and neurological diseases. We have improved a chromatographic method of total plasma homocysteine measurements in order to obtain higher sensitivity, reliability and reproducibility. The method demonstrates excellent linearity (R = 0.999), range (< 2-100 µM), precision (instrumental RSD 0.06 and method RSD 1.17), accuracy (recovery of 99.92 and RSD 1.27), reproducibility, quantification limit and ruggedness (e.g. pH from 2.0 to 2.5). Because even a small increase in homocysteine level can be a significant risk factor of cardiovascular diseases, such a precise method is required. The constructed method allows the measurement of plasma pyridoxal phosphate, PLP, the co-enzyme form of vitamin B6, on the same column and similar reagents. The developed method has been successfully applied to measure both total plasma and serum homocysteine in a group of acute stroke patients.

Opis:
Rapid detection and quantification of microorganisms, particularly their nucleic acids and proteins, appears to be crucial in clinical practice, veterinary medicine, agriculture, basic research as well as in biotechnological factories. Although various techniques were described and are currently used, development of more rapid, more sensitive and quantitative methods seems to be still important. Here we describe a method for rapid detection of nucleic acids, proteins and small molecules, based on electrical biochip technology. This method is quick and sensitive. It can be thus expected that electrical bio-chips will soon be commonly used in biotechnology and medicine.
