Civic Education for Sustainable Development
Authors: Ohlmeier Bernhard 
Published: June 2013

Abstract
Education for sustainable development (ESD) often fails to consider the political dimension. To address this gap, this paper focuses on a specific political approach to ESD. The model presented is derived from the four sustainable growth targets of German Development Policy. Instead of relying on a neo-classical or neo-liberal economic paradigm, however, the goals of social justice, environmental sustainability, economic productivity and good governance are interpreted using a sustainability model. This model is anchored in a steady-state economy that has overcome the myth of unlimited material growth and seeks to stay within the limits of the planet's resources. The preconditions of good governance are outlined, and it is described how the state and civil society can contribute to this normative goal. In addition to social, ecological, economic and political components, the presented model for civic education for sustainability considers conflicts between different development components and the need for horizontal and vertical coherence. In conclusion, the paper shows that civic education for sustainability must aim to produce informed and empowered global citizens. Citizens should have the ability to employ their knowledge and skills responsibly through local and global civic involvement while also remaining aware of their own interests. Furthermore, it falls to educational policy makers to create national as well as international organisational structures that facilitate civic ESD.
Latvian Piano Teachers' Views on an Ideal Teaching Aid for Pupils - Young Pianists
Authors: Zīmele-Steina Ineta 
Published: June 2013

Abstract
Currently, in Latvia, an adequate teaching aid that would meet the major requirements of young novice pianists is not available. Consequently, a question arises: What could be an ideal teaching aid for them? The opinion survey of 165 piano teachers from all regions of Latvia was carried out according to a three-point scale, in which 30 parameters that would characterise the teaching aid were indicated. The quantitative and qualitative methods of data processing were applied in this research. The results of the survey show that an ideal teaching aid for young novice pianists should correspond to the pupils' age group and be multinational. The results of the empiric research were used to articulate the basic principles of the development of teaching aids.
Values Education - a Reality or Myth in Polish Schools
Authors: Świtała Eugeniusz 
Published: June 2013

Abstract
The United Nations Decade of Education for Sustainable Development (DESD), which is coming to an end, will offer all kinds of summaries and reflections on this issue. The aim of this paper, strictly related with the goals of the DESD, is to answer the following questions: (1) Is the Polish school ready to provide values education?; (2) How are schools trying to involve values education into the school practice?; (3) To what extent do the adopted solutions regarding programmes, curricula and textbooks match the requirements of values education, which is one of the pillars of education for sustainable development? The author presents an analysis of the content of selected curricula for the early stage of education and the textbooks used at this stage, paying special attention to values education based on pupils' and teachers' activities and experiences. The results of the analysis provide an unequivocal answer to the extent to which we are prepared to provide or to implement values education at this stage of instruction.
The Earth Charter: An Ethical Framework for a Feasible Utopia
Authors: Contini Valerio , Garcia Pascual Enrique 
Published: June 2013

Abstract
This research objective is to highlight an innovative, holistic, inclusive, integrated approach to a sustainable future promoted by the Earth Charter and describe the structure of its ethical framework. The main conclusion of the research is that the ethical framework of the Earth Charter is based on a limited number of core concepts: planetary human identity, feasible utopianism, co-responsibility and committed compassion. Planetary human identity is based on the capacity to incorporate nature into the process of identity building and integrate three complementary feelings: singularity, belonging to groups and belonging to the planetary community of life. The Earth Charter stresses the necessity to give a new life to utopianism by working out a critical-radical-alternative, but a feasible idea of future and our responsibility towards it. Moreover, the Earth Charter rethinks responsibility as co-responsibility and assigns it four different qualities: universal, synchronic, diachronic and differentiated and appeals to an innovative politically connoted notion of compassion.
Review of research on haploid production in cucumber and other cucurbits
Authors: Gałązka Joanna , Niemirowicz-Szczytt Katarzyna 
Published: June 2013

ABSTRACT
This review provides a summary of haploid induction methods and factors affecting the efficacy of specific methodologies as applied to cucumber (Cucumis sativus L.), melon (Cucumis melo L.), watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai), winter squash (Cucurbita maxima Duch. ex Lam.), summer squash (Cucurbita pepo L.) and other cucurbits. This report is focused on studies that were carried out during the last 20 years.
The main objective of the research on the production of haploid cucurbit plants is to accelerate breeding programs through the use of homozygous double haploid lines (DHL) and to facilitate the selection of desired (e.g. disease-resistant) genotypes for breeding. Unfortunately, currently used protocols result in a low number of double haploids (DH). The most common and best-known method of obtaining haploid cucurbit plants is via pollination with irradiated pollen, which induces parthenogenetic development of haploid embryos in planta. The embryos are extracted from immature seeds and cultured in vitro to facilitate the maturation and development of plants. The studies described below were primarily aimed at the determination of an appropriate dose of radiation and the evaluation of the impact of the genotype and the time of year on the number of haploid embryos and plants obtained.
A less popular method of haploid production - ovule and ovary culture - is based on in vitro gynogenesis. The studies related to this method concentrated on optimising the composition of the medium and pre-treatment conditions (primarily temperature) to which the flower buds were subjected.
Recently, increasing attention has been paid to anther and microspore culture. As in the case of in vitro ovule and ovary culture, the medium composition and flower bud pre-treatment conditions were optimised. The most recent studies suggest that anther culture is comparable in effectiveness to the irradiated pollen technique.
Potential utilisation of vegetables and mushrooms as components of functional food
Authors: Sobieralski Krzysztof , Siwulski Marek , Sas-Golak Iwona 
Published: June 2013

ABSTRACT
The importance of functional products on the world food market is increasing systematically. This has resulted from enhanced consumer awareness that health improvement may be attained through appropriate nutrition. Functional products are targeted to different groups of consumers who have increased nutrient requirements or are designed to improve specific functions of the organism. The market for functional food is also developing in Poland, but its growth rate is much slower than in other European countries. Moreover, knowledge on issues concerning functional food among Polish consumers is also low. Vegetables and mushrooms occupy an important position among functional food products due to their contents of many bioactive components that have a beneficial effect on human health and sense of well being. Vegetables in an everyday diet are natural sources of dietary fibre, vitamins, minerals, anthocyanin, carotenoids and substances with an anti-carcinogenic effect. The fruiting bodies of both cultivated and wild-growing mushrooms contain several active substances, including polysaccharides, triterpenoids, specific proteins and phenolic compounds. Their positive effect for humans results from the interaction of different active components contained in their fruiting bodies. Several health-promoting properties of mushrooms have been documented, including anti-cancer, immunostimulatory, antioxidant, antibacterial, antiviral and anti-diabetic effects. Consumers should have knowledge on the potential for health improvement thanks to the inclusion of vegetables and mushrooms in their everyday diets.
The current growth increment of pine tree stands comprising three different age classes
Authors: Kaźmierczak Katarzyna 
Published: June 2013

Abstract
The study presents the results of an analysis of the pine tree growth increments (height increment, dbh increment, basal area increment and volume increment) for a 5-year period. The study involved Scots pine trees of Kraft’s class 1, 2 and 3 (dominant stand) in stands of different age classes (II, III, V) growing in fresh mixed coniferous (BMśw) and fresh coniferous (Bśw) forest habitats. The multivariate analysis of variance was performed to assess the statistical significance of age and dominance of trees within a stand on their increment. The dominance position was classified for each tree using Kraft’s criteria. The following characteristic were also measured: dbh of the trunk in two directions (N-S and W-E), and crown projection area on the basis of the characteristic tree crown points, projected using of a crown projector, characteristic points in tree crowns (7 to 14 on average). The actual height was determined after trees were felled. The following measurements of the single tree growing space were selected and determined: crown projection area - pk (m2), crown diameter - dk (m), Seebach’s growth space number - dk / d1.3, crown projection area to basal area ratio d 2 k / d 2 1.3, crown deflection coefficient dk / h, single tree space ppd = pk·h (m3). We assessed the strength of the relationships between tree growth parameters and tree growth space, crown length, relative crown length and slenderness. Both the age and dominance position of trees within the stand affected the growth increments. The strongest correlation among measured traits was between the 5-year volume increment and decreasing slenderness.
Substrate influences the height of one- and two-year-old seedlings of silver fir and European beech growing in polystyrene containers
Authors: Banach Jacek , Skrzyszewska Kinga , Świeboda Łukasz 
Published: June 2013

Abstract
The effectiveness of different peat-based substrates was compared for the propagation of two mountain tree species (silver fir and European beech). The experiment was set up in the spring of 2006, and seedlings were grown in polystyrene multipots for 2 years. Four types of substrate were applied: (1) a newly prepared 1:1 peat-sawdust mixture; (2) a peat-sawdust mixture which had already been used for five production periods; (3) a peat substrate produced in the ‘Nędza’ container nursery (Rudy Raciborskie Forest District), consisting of peat and perlite; (4) a peat substrate, as described for (3), with added mycorrhizal fungus Hebeloma crustuliniforme. After sowing, polystyrene multi-pots were placed in a transparent tent.
During the autumns of 2006 and 2007, for both species and each substrate type, 25 seedlings were randomly selected for measurement of their above-ground height, root length, root collar diameter, above- and below-ground fresh weight.
Growth of one-year old and two-year-old seedlings of both species differed depending on their substrate. The application of a mycorrhizal inoculum positively affected seedling establishment, since the best height growth and largest seedlings of both species were grown on substrate (4). The growth of one-year-old fir seedlings in the ‘old’ peat and sawdust mixture (2) was similar to those seedlings grown on the turf substrate (3). Root:shoot allocation differed among the substrates. In fir, root:shoot allocation was approximately equivalent at 1:0.9, whereas for beech it was 1:2 in one-year old seedlings and 1:1.5 in two-year old seedlings.
Prevalence and malignancy risk of focal colorectal incidental uptake detected by 18F-FDG-PET or PET/CT: a meta-analysis
Authors: Treglia Giorgio , Taralli Silvia , Salsano Marco , Muoio Barbara , Sadeghi Ramin , Giovanella Luca 
Published: June 2013

Abstract
Background. The aim of the study was to meta-analyze published data about prevalence and malignancy risk of focal colorectal incidentalomas (FCIs) detected by Fluorine-18-Fluorodeoxyglucose positron emission tomography or positron emission tomography/computed tomography (18F-FDG-PET or PET/CT).
Methods. A comprehensive computer literature search of studies published through July 31st 2012 regarding FCIs detected by 18F-FDG-PET or PET/CT was performed. Pooled prevalence of patients with FCIs and risk of malignant or premalignant FCIs after colonoscopy or histopathology verification were calculated. Furthermore, separate calculations for geographic areas were performed. Finally, average standardized uptake values (SUV) in malignant, premalignant and benign FCIs were reported.
Results. Thirty-two studies comprising 89,061 patients evaluated by 18F-FDG-PET or PET/CT were included. The pooled prevalence of FCIs detected by 18F-FDG-PET or PET/CT was 3.6% (95% confidence interval [95% CI]: 2.6-4.7%). Overall, 1,044 FCIs detected by 18F-FDG-PET or PET/CT underwent colonoscopy or histopathology evaluation. Pooled risk of malignant or premalignant lesions was 68% (95% CI: 60-75%). Risk of malignant and premalignant FCIs in Asia-Oceania was lower compared to that of Europe and America. A significant overlap in average SUV was found between malignant, premalignant and benign FCIs.
Conclusions. FCIs are observed in a not negligible number of patients who undergo 18F-FDG-PET or PET/CT studies with a high risk of malignant or premalignant lesions. SUV is not reliable as a tool to differentiate between malignant, premalignant and benign FCIs. Further investigation is warranted whenever FCIs are detected by 18F-FDG-PET or PET/CT
Magnetic resonance imaging of vulvar dermatofibrosarcoma protuberans – report of a case
Authors: Ozmen Evrim , Güney Güven , Algin Oktay 
Published: June 2013

Abstract
Background. Dermatofibrosarcoma protuberans (DFSP) of the vulva is a rare low-grade soft tissue sarcoma. Magnetic resonance imaging (MRI) findings of vulvar DFSP were essentially unreported in the literature.
Case report. We report a DFSP of vulva with its clinical, histological and MRI features. As far we know this is the first case of histologically confirmed vulvar DFSP presenting with MR images. The diagnosis of DFSP is usually made by histopathologic and clinical findings.
Conclusions. MRI is useful both for the diagnosis of DFSP and following up the patients since it has high soft tissue resolution and no risk of radiation exposure. With MRI the relation to the adjacent anatomical structures, extension and depth of the tumour and possible lymph node involvement can also be demonstrated.
Inhibition of cathepsin X enzyme influences the immune response of THP-1 cells and dendritic cells infected with Helicobacter pylori

Published: June 2013

Abstract
Background. The immune response to Helicobacter pylori importantly determines the outcome of infection as well as the success of eradication therapy. We demonstrate the role of a cysteine protease cathepsin X in the immune response to H. pylori infection.
Materials and methods. We analysed how the inhibition of cathepsin X influenced the immune response in experiments when THP-1 cells or dendritic cells isolated from patients were stimulated with 48 strains of H. pylori isolated from gastric biopsy samples of patients which had problems with the eradication of bacteria.
Results. The experiments, performed with the help of a flow cytometer, showed that the expression of Toll-like receptors (TLRs), especially TLR-4 molecules, on the membranes of THP-1 cells or dendritic cells was higher when we stimulated cells with H. pylori together with inhibitor of cathepsin X 2F12 compared to THP-1 cells or dendritic cells stimulated with H. pylori only, and also in comparison with negative control samples. We also demonstrated that when we inhibited the action of cathepsin X in THP-1 cells, the concentrations of pro-inflammatory cytokines were lower than when THP-1 cell were stimulated with H. pylori only.
Conclusions. We demonstrated that inhibition of cathepsin X influences the internalization of TLR-2 and TLR-4. TLR-2 and TLR-4 redistribution to intra-cytoplasmic compartments is hampered if cathepsin X is blocked. The beginning of a successful immune response against H. pylori in the case of inhibition of cathepsin X is delayed.
Disparités fiscales et redistribution territoriale : de la coordination subie à la coordination choisie
Authors: Duran-Vigneron Pascale 
Published: June 2013

La question des disparités fiscales se pose aujourd’hui de manière accrue et renouvelée avec l’ouverture européenne et la globalisation qui induisent une concurrence des territoires toujours plus forte dont les risques en termes de cohésion spatiale sont très importants. Une réflexion sur les outils de traitement de la question sensible des disparités territoriales s’avère donc tout à la fois pertinente et nécessaire. Nous distinguons deux approches : « fiscale » et « territoriale ». L’approche fiscale vise à traiter ex post les inégalités résultant du système de fiscalité locale à travers des mécanismes de redistribution quand l’approche territoriale tend à définir des règles du jeu qui amènent les acteurs publics à se préoccuper ex ante des conséquences de leurs choix. Caractéristiques de ces deux approches, la péréquation financière et la coopération intercommunale renvoient à des finalités et des méthodologies différentes qu’il convient ici d’analyser afin d’apporter une réflexion nouvelle sur la mise en œuvre et l’impact des politiques de redistribution territoriale.
Influence of Two Different Bracket Base Cleaning Procedures on Shear Bond Strength Reliability
Authors: Aksu Muge , Kocadereli Ilken 
Published: June 2013

ABSTRACT

Purpose
To search if the shear bond strengths of brackets would change after two different base-cleaning procedures such as sandblasting or carbide bur cleaning, and to determine if a previously bonded tooth surface had any effect on bond strength.

Materials and methods
A total of 120 new brackets were first bonded to 120 extracted premolars and then debonded and bond strength was recorded. The debonded brackets were divided into two groups and recycled either by sandblasting or tungsten-carbide bur cleaning. Sixty recycled brackets were divided into two subgroups: In each group; 30 recycled brackets were bonded to unused 30 extracted premolars. The remaining brackets were bonded to 30 previously used premolars. The brackets were debonded again and their bond strengths were remeasured.

Results
Bond strength of rebonded brackets after sandblasting was not significantly different from that of new brackets while the bond strength of rebonded brackets after carbide bur cleaning group significantly decreased. The previously bonded tooth surface did not affect the bond strength significantly.

Clinical significance
This study showed that rebonding the brackets after sandblasting supplies sufficient bond strength. Previously bonded tooth surface did not cause a decreasing effect on bond strength. However, when carbide bur cleaning procedure is chosen, the clinician should proceed cautiously.

Published: June 2013

ABSTRACT

Aim
The aim of this study was to quantify and compare the amount of methyl methacrylate (MMA) monomer released from three different denture base acrylic material processed by different polymerization methods and storage conditions.

Materials and methods
Microwave-cured, conventional heat and injection-technique acrylic polymerized materials were stored in neutral (pH = 7) and acidic (pH = 4.5) artificial saliva for 24 hours at the room temperature, separately. The residual MMA content was determined by high performance liquid chromatography (HPLC).

Results
The MMA leaching from resins showed that microwave-cured material has lower residual MMA leach compared both conventional and injection-technique on neutral saliva storage conditions.

Conclusion
The all data's exhibited higher MMA release into an acidic saliva environment than neutral artificial saliva and there were no significant differences between the materials groups on acidic saliva storage conditions.

Clinical significance
Microwave polymerization method might has some advantages on reducing release of MMA concentration and may contributory effect upon polymerization reaction on neutral pH storage condition, therefore methods of polymerization should be considered as amount of monomer release.

A New Solvent-free One-Step Self-Etch Adhesive: Bond Strength to Tooth Structures
Authors: Khoroushi Maryam , Shirban Farinaz , Shirban Mohammadreza 
Published: June 2013

ABSTRACT

Introduction
In recent years some new solvent-free dental adhesives have been marketed. This study evaluated bonding effectiveness of a new one-step solvent-free self-etch adhesive in comparison with a common two-step self-etch adhesive used as gold standard.

Materials and methods
Flat enamel and dentin surfaces were prepared on 60 incisors using silicon carbide papers. Clearfil SE Bond (CSEB) and Bond 1SF (B1SF) adhesives were applied on enamel/dentin surfaces in four groups (n = 15): (1) Enamel surface and CSEB, (2) dentin surface and CSEB, (3) enamel surface and B1SF, (4) dentin surface and B1SF. Composite resin buildups were carried out using Z100 composite resin. All the specimens were stored for 24 hours at 37¢XC and 100% relative humidity. After 500 rounds of thermocycling, shear bond strength (SBS) test was performed using a universal testing machine at 1 mm/min crosshead speed. Data were analyzed with one-way ANOVA and a post hoc Tukey test (α = 0.05). In each experimental group, two additional specimens were prepared for scanning electron microscopy evaluation.

Results
Significant differences were observed between the study groups (p < 0.001). The highest enamel/dentin bond strengths were recorded in group 1 (CSEB) (p < 0.001). The SBS of the two-step self-etch adhesive to enamel and dentin was significantly higher than that of the one-step self-etch adhesive (p < 0.001). There was no significant difference between enamel and dentin SBS with B1SF (p = 0.559).

Conclusion
Within the limitations of the present study, when bonded to enamel and dentin the solvent-free adhesive B1SF underperforms as compared to CSEB as the control gold standard.
