Blood lipids may have influence on the emotional well-being in young men  [PDF]
Edyta Kramek, Sylwia Jastrzebska, Renata Walczak-Jedrzejowska, Katarzyna Marchlewska, Elzbieta Oszukowska, Anna Guminska, Krzysztof Kula, Jolanta Slowikowska-Hilczer
Health (Health) , 2010, DOI: 10.4236/health.2010.25066
Abstract: Anamnestic data on general health and medical conditions were achieved from 136 men (20-49 yrs). Beck Depression Inventory II (BDI-II) questionnaire was used to assess depressive symptomatology. Body weight, height, waist and hip circumference, arterial blood pressure were mea- sured. Serum levels of total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), triglicerydes (TG), glucose, SHBG, total testosterone, DHEA-S and estradiol were determined. Calculated were body mass index (BMI), waist to hip ratio (WHR) and free testosterone index (FTI). In men aged 40-49 general health significantly got worse, BMI, WHR, blood pressure increased and mean serum levels of FTI, DHEA-S, estradiol decreased in comparison to younger men. Only in 40-49 age band BDI-II scoring was negatively related with FTI, however, in the whole group there were no significant correlations. Nevertheless, some symptoms of depression were negatively related with LDL-C or HDL-C and positively with TG. Similar relations were found among young men, but not in the middle-aged. Conclusions: Only blood lipids may have influence on emotional well-being in young healthy men. The decreased testosterone level becomes probably the main risk factor for the lower mood in middle-aged men. Atherosclerosis risk factors and general health worsen with the advancing age, but they have no significant effect on psychological situation.

On the Properties of the M bius Function
Magdalena Jastrzebska , Adam Grabowski
Formalized Mathematics , 2006, DOI: 10.2478/v10037-006-0005-0
Abstract: We formalized some basic properties of the M bius function which is defined classically as as e.g., its multiplicativity. To enable smooth reasoning about the sum of this number-theoretic function, we introduced an underlying many-sorted set indexed by the set of natural numbers. Its elements are just values of the M bius function. The second part of the paper is devoted to the notion of the radical of number, i.e. the product of its all prime factors. The formalization (which is very much like the one developed in Isabelle proof assistant connected with Avigad's formal proof of Prime Number Theorem) was done according to the book [13].
The interleukin-1 receptor antagonist (IL-1-Ra) and soluble tumor necrosis factor receptor I (sTNF RI) in periodontal disease  [PDF]

Open Journal of Immunology (OJI) , 2013, DOI: 10.4236/oji.2013.31002
Abstract: The course and severity of periodontitis can be significantly affected by bacterial virulence as well as host immunity dysfunction. Periodontal tissue destruction has been proved to result from cascade of cytokines synthesized by reactive cells upon stimulation by pathogenic bacteria and lipopolysaccharides within their cell membranes. The clinical use of genetically programmed cells, producing substances blocking IL-1, based on recombinant IL-1 antagonist, as well as cytokines activating fibroblasts and osteoblasts to regenerate the destroyed periodontal tissue could prove alternative to the conventional treatment. Another cytokine of interest in respect to periodontitis ethiopathogenesis is soluble tumor necrosis factor receptor I (sTNF RI). Observation of soluble TNF receptors as physiologic inhibitors of TNF led to its administration in therapeutic process as well as in therapy selected cases of aggressive periodontitis.
Generation of Useful Hydrocarbons and Hydrogen during Photocatalytic Decomposition of Acetic Acid on CuO/Rutile Photocatalysts
Sylwia Mozia
International Journal of Photoenergy , 2009, DOI: 10.1155/2009/469069
Abstract: The presented studies have focused on a photocatalytic generation of useful hydrocarbons, mainly methane and ethane, from acetic acid under N2 atmosphere. CuO-loaded rutile, as well as unmodified rutile and anatase-phase TiO2 photocatalysts were applied in the experiments. The efficiency of the catalysts towards methane generation changed in the following order: Cu-TiO2 (10% Cu) > crude TiO2≈Cu-TiO2 (20% Cu) > Cu-TiO2 (5% Cu) > rutile. The amount of CH4 produced in the presence of the catalyst containing 10 wt% of Cu was higher for ca. 33% than in case of pure rutile. The concentration of ethane was 14–16 times lower than the amount of methane, regardless of the catalyst used. Low concentrations of hydrogen were also detected in the gaseous mixtures. After 5 hours of the process conducted with the catalyst containing 5–20 wt% of Cu the concentration of hydrogen amounted to 0.06–0.14 vol.%, respectively.
2-splittable and cordial graphs

Abstract: E. Miller and G.E. Stevens proved in [5] the existence of certain families of 2-splittable caterpillars. In this paper we characterize other families of 2-splittable caterpillars. Moreover, we show that for some of them there exists a friendly labeling inducing two isomorphic subgraphs.

Identification of powdery mildew resistance genes in Polish common oat (Avena sativa L.) cultivars using host-pathogen tests
Sylwia Okoń
Acta Agrobotanica , 2012, DOI: 10.5586/aa.2012.008
Abstract: The aim of the present study was to characterize and identify powdery mildew resistance genes in Polish common oat cultivars using host-pathogen tests. A differential set of six Blumeria graminis f.sp. avenae isolates virulent or avirulent to four cultivars and one line that has known resistance to powdery mildew were used. Among the investigated cultivars, only four of them (13.3%) had resistance patterns similar to genotypes belonging to the differential set. The resistance of OMR group 1 was found in the cultivar ‘Dragon’, while that of OMR2 in the cultivar ‘Skrzat’. The cultivars ‘Deresz’ and ‘Hetman’ showed a resistance pattern that corresponded with OMR group 3. The resistance corresponding to OMR4 was not found, which suggests that until now this gene has not been used in Polish oat breeding programmes. The cultivar ‘Canyon’ had a different pat- tern of resistance than the genotypes that have already known OMR genes, which indicates that the resistance of this cultivar is determined by a new gene or a combination of known genes.
Three evaluation experiments in the context of the development of a sub-sentential alignment system Trois expériences d'évaluation dans le cadre du développement d'un système d'alignement sous-phrastique

Abstract: We present the approach we adopted to carry out a system oriented evaluation in the context of the development of a word alignment system, ALIBI. We look at three evaluation procedures corresponding to fundamental aspects in the development of natural language processing systems: an evaluation resulting from the annotation performed on output alignments to accurately examine the behaviour of each module under study, an evaluation with multicorpus references allowing to observe the behaviour of a system depending on the type of input corpus and an evaluation with a standard reference allowing to observe its behaviour in comparison with other systems of the same type. We describe each procedure and discuss the measures particular to each of them as well as their contribution to system oriented evaluation.
Poland’s Return To Europe: Polish Terrestrial Broadcasters And TV Fiction
Sylwia Szostak
View : Journal of European Television History and Culture , 2012,
Abstract: The changing political sphere in 1989 and the subsequent 2004 European Union accession had a profound impact on Poland’s economic, political and social spheres. Both events are considered to have marked Poland’s ‘return to Europe’ and strengthened the relations with its Western neighbours. This article examines the changing patterns of television fiction programming flow in Poland in the post-Soviet era, exploring the impact of those two events on Poland’s audiovisual sector. This article therefore assesses whether, and if so – how, this metaphorical ‘return to Europe’ is manifested on Polish television screens.
