Automatic Counting of Intra-Cellular Ribonucleo-Protein Aggregates in Saccharomyces cerevisiae Using a Textural Approach.
2019
AbstractIn the context of microbiology, recent studies show the importance of ribonucleo-protein aggregates (RNPs) for the understanding of mechanisms involved in cell responses to specific environmental conditions. The assembly and disassembly of aggregates is a dynamic process, the characterization of the stage of their evolution can be performed by the evaluation of their number. The aim of this study is to propose a method to automatically determine the count of RNPs. We show that the determination of a precise count is an issue by itself and hence, we propose three textural approaches: a classical point of view using Haralick features, a frequency point of view with generalized Fourier…
Understanding Factors Affecting Well-Being of Marginalized Populations in Different Cultural Contexts: Ethnic and National Identity of Roma Minority …
2018
This chapter focuses on the intersection of the third, fourth and tenth Sustainable Development Goals (SDGs), referring together to key pillars for improving social inclusion of vulnerable disadvantaged youth. Based on both Positive Youth Development approach and mutual intercultural relations perspective, it sets out to investigate developmental assets (such as ethnic and national identities), optimal outcomes (self-esteem), and their relations among Roma youth in six European countries (Albania, Bulgaria, the Czech Republic, Italy, Kosovo, and Romania). Among these countries, the Czech Republic was initially recognized as the more favorable context facilitating potential alignment of Roma…
Hybridity Maintained, Reduced, Abolished and Redefined: The Czech Graphic Novel Alois Nebel (Jaroslav Rudiš, Jaromír 99, 2006) in Polish and German
2016
This study is devoted to comparative analysis of hybridity in Jaroslav Rudis’s and Jaromir Svejdik’s Graphic Novel Alois Nebel – the trilogy in book-form, 2006 (2011) – and the Polish and German translations. The basic forms of hybridity are intermedial (picture and text) hybridity, linguistic hybridity (given by elements of German, Russian, English, Polish and Slovak together with Czech main text), graphic hybridity (between Latin and Cyrillic script, printed and hand-written characters), and hybridity of discourse (interpersonal communication, telling, personal reflection, non-fiction text etc.). While the Polish text – privileged by translation between two West Slavic languages – maintai…
Co-authorship networks and institutional collaboration in works about Learning, Teaching and Education Leadership
2017
Bibliometric indicators, based on the statistical analysis of quantitative data from scientific literature, constitute currently in an essential tool for the study of research activity. In the last years, the use of bibliometric indicators as a complement to other scientific indicators to analyse the research situation of a country, its evolution in its time and their position in the international context, has been extended. Collaboration is a characteristic feature of modern science and it is very difficult to measure this aspect. Nevertheless, it is widely accepted to count the combined signatures done by two or more authors, with the analysis of the institutional affiliation mentions and…
Can Cross-Border Healthcare Be Sustainable? An Example from the Czech-Austrian Borderland
2019
Cross-border public services are considered to be one of the possible tools to eliminate the periphery position of border regions. The Czech part of the Gmü
Vertical Governance, National Regulation and Autonomy of Local Policy Making
2015
International audience; This chapter introduces a categorization of the 11 European countries according to their general vertical governance structures between national, regional and local levels in welfare policy making. It investigates the extent to which, and how, local policies and service provision are regulated and controlled from the national state level, and how much space this leaves for local policy actors in welfare policy formation. The analysis takes into account that local welfare policies are formulated in the context of national and to some extent international policies. The 11 countries can be divided into three groups, having a centralized (England, Ireland), multi-level (…
PREDICTION OF HARVEST TIME IN PEACH [PRUNUS PERSICA (L.) BATSCH] FRUIT USING THE DA-METER
2015
The aim of this work was to define the most appropriate time of harvesting early ripening peach fruit using destructive and non-destructive quality indexes such as the index of absorbance (IAD), measured with the DA-Meter, a portable equipment able to measure the degradation of chlorophyll in the pericarp. In this context our research was carried out in 2009 and 2010 on several peach cultivars. Total soluble solid content increased while flesh firmness and total acidity decreased with IAD values, but no significant correlation was found between destructive and non-destructive parameters.
Mutational Events in Cefotaximase Extended-Spectrum β-Lactamases of the CTX-M-1 Cluster Involved in Ceftazidime Resistance
2008
ABSTRACT CTX-M β-lactamases, which show a high cefotaxime hydrolytic activity, constitute the most prevalent extended-spectrum β-lactamase (ESBL) type found among clinical isolates. The recent explosive diversification of CTX-M enzymes seems to have taken place due to the appearance of more efficient enzymes which are capable of hydrolyzing both cefotaxime and ceftazidime, especially among the CTX-M-1 cluster. A combined strategy of in vitro stepwise evolution experiments using bla CTX-M-1 , bla CTX-M-3 , and bla CTX-M-10 genes and site-directed mutagenesis has been used to evaluate the role of ceftazidime and other β-lactam antibiotics in triggering the diversity found among enzymes belong…
DNA extraction from soils: old bias for new microbial diversity analysis methods.
2001
ABSTRACT The impact of three different soil DNA extraction methods on bacterial diversity was evaluated using PCR-based 16S ribosomal DNA analysis. DNA extracted directly from three soils showing contrasting physicochemical properties was subjected to amplified ribosomal DNA restriction analysis and ribosomal intergenic spacer analysis (RISA). The obtained RISA patterns revealed clearly that both the phylotype abundance and the composition of the indigenous bacterial community are dependent on the DNA recovery method used. In addition, this effect was also shown in the context of an experimental study aiming to estimate the impact on soil biodiversity of the application of farmyard manure o…
Microbiological quality of carbonated drinking water produced with in-home carbonation systems.
2005
The microbiological quality of carbonated water produced with tap water in commercial in-home carbonation systems was determined, the results being discussed in the context of the microbiological quality of the tap water used, the properties of the drink makers, and the procedures of preparation and washing of various parts of the appliance. The last-mentioned data were received from each participant of the study by questionnaire. Escherichia coli, coliforms, fecal streptococci and spore-forming sulphite-reducing anaerobes were used as indicators for the hygienic quality of the water. Tap-water samples were collected according to the usual procedure when filling the carbonating bottle, i.e.…
