Production, stability, gene sequencing and in situ anti-Listeria activity of mundticin KS expressed by three Enterococcus mundtii strains
2014
Three enterococci (WFE3, WFE20 and WFE31) selected as presumptive bacteriocin producers were found to be active against Listeria monocytogenes. In this study, due to their potential industrial/food applications, the three bacterial isolates were extensively characterized. Identification was performed by means of a combined 16S rRNA gene sequencing and multiplex PCR approach, and was confirmed with the sequencing of a partial region of a protein-encoding gene, namely pheS. The three isolates belonged unequivocally to the species Enterococcus mundtii. The randomly amplified polymorphic DNA (RAPD) analysis recognized three distinct strains. The supernatants were mainly active against Listeria …
Biological control of Listeria monocytogenes in soil model systems by Enterococcus mundtii strains expressing mundticin KS production
2022
Abstract The agricultural practices applied in pre-harvest greatly influence the presence and the levels of microorganisms in fresh produce. Among these, Listeria monocytogenes represents one of the most lethal foodborne pathogens associated with vegetables. The main hypothesis of this work is that bacteriocin producer Enterococcus mundtii strains can be effective against L. monocytogenes in soil. To this purpose, bacteriocin production by E. mundtii WFE3, WFE20 and WFE31, three strains showing a strong bacteriocin activity in terms of inhibitory power and inhibition spectra, was evaluated in sterile extracts from agricultural soil and peat moss, in organic nutrient solution (ONS) and miner…
Microbial interactions in food model systems: In situ antilisterial activity of mundticin KS producing strains
2013
It is known that microbial interactions are important for the success of food fermentations, as well as for the establishment of the safety of the final products. In this study, we characterized extensively three enterococci (WFE3, WFE20 and WFE31) of flour origin, which were found to be active against Listeria monocytogenes, in order to investigate on their ability to produce bacteriocins in complex food model systems for their future industrial/food applications. The identification of the three bacterial isolates was performed by means of a combined 16S rRNA gene sequencing and multiplex PCR approach. Two isolates belonged unequivocally to the species E. mundtii, while one isolate could n…
A magically nice guy: Parasocial relationships with Harry Potter across different cultures
2011
This study explored parasocial relationships (PSRs) with Harry Potter that readers from different cultures have developed. An overall sample of 2551 Potter fans from Germany (individualistic culture) and Mexico (collectivistic culture) completed an online questionnaire assessing their parasocial relationship with the character. Fans from the collectivistic culture rated Potter’s sociability higher than fans from the individualistic culture. For fans from both cultures, social attraction turned out as most important determinant of PSRs with Potter, while homophily ranked lowest. Overall, PSRs and fandom turned out to be quite similar across cultures, with some differences in character perce…
Bolstering firm growth : Kasvu Open 2014
2015
There has been a significant increase in SME growth research in recent years as its macroeconomic effect has become better understood. Firm growth has a significant influence on national economic health, especially small economies such as Finland, yet scholars agree that little is known about the phenomena. Authors of this study aim deliver a broader and more holistic approach to firm growth research and integrate currently fragmented constructs. By studying participants of Kasvu Open 2014, this study contributes to firm growth research by providing a new and unique context. Existing firm growth research has examined the effect of growth intention on firm growth, but few studies have addres…
Bayesian inference analysis of the uncertainty linked to the evaluation of potential flood damage in urban areas.
2012
Flood damage in urbanized watersheds may be assessed by combining the flood depth–damage curves and the outputs of urban flood models. The complexity of the physical processes that must be simulated and the limited amount of data available for model calibration may lead to high uncertainty in the model results and consequently in damage estimation. Moreover depth–damage functions are usually affected by significant uncertainty related to the collected data and to the simplified structure of the regression law that is used. The present paper carries out the analysis of the uncertainty connected to the flood damage estimate obtained combining the use of hydraulic models and depth–damage curve…
The Analysis of the Factors Influencing the Severity of Bicyclist Injury in Bicyclist-Vehicle Crashes
2021
Transportation and technological development have for centuries strongly influenced the shaping of urbanized areas. On one hand, it undoubtedly brings many benefits to their residents. However, also has a negative impact on urban areas and their surroundings. Many transportation and technological solutions lead, for example, to increased levels of pollution, noise, excessive energy use, as well as to traffic accidents in cities. So, it is important to safe urban development and sustainability in all city aspects as well as in the area of road transport safety. Due to the long-term policy of sustainable transport development, cycling is promoted, which contributes to the increase in the numb…
Typification of the NameKochia saxicola(Chenopodiaceae)
2013
The typification of the name Kochia saxicola Guss. [= Eokochia saxicola (Guss.) Freitag & G. Kadereit] (Chenopodiaceae) is here discussed, and a specimen from the Gussone collection (NAP) is designated as the lectotype. The distribution of the species is given and remarks on its IUCN conservation status are provided.
Pharmacotherapy, drug-drug interactions and potentially inappropriate medication in depressive disorders.
2021
Introduction The aim of this study was to describe the number and type of drugs used to treat depressive disorders in inpatient psychiatry and to analyse the determinants of potential drug-drug interactions (pDDI) and potentially inappropriate medication (PIM). Methods Our study was part of a larger pharmacovigilance project funded by the German Innovation Funds. It included all inpatients with a main diagnosis in the group of depressive episodes (F32, ICD-10) or recurrent depressive disorders (F33) discharged from eight psychiatric hospitals in Germany between 1 October 2017 and 30 September 2018 or between 1 January and 31 December 2019. Results The study included 14,418 inpatient cases.…
Copy number variations in the etiology of epilepsy
2013
Epilepsy is one of the most common neurological disorders in humans with a prevalence of 1% and a lifetime incidence of 3%. Idiopathic epilepsies occur in the absence of identifiable causal factors, but recent evidences show the role of genetic factors in the developing of these disorders. In particular, several studies focused their attention on the role of copy number variations (CNVs) in the etiology of epilepsy. In recent years, many CNVs have been identified, like 15q11.2, 15q13.3 and 16p13.11 microdeletions, 22q11.2 microduplication and many others. Possible candidate genes included in these regions were also studied and they seem to be involved in neuronal transmission and ion transp…
