Survival of Listeria monocytogenes in Soil Requires AgrA-Mediated Regulation
2015
ABSTRACT In a recent paper, we demonstrated that inactivation of the Agr system affects the patterns of survival of Listeria monocytogenes (A.-L. Vivant, D. Garmyn, L. Gal, and P. Piveteau, Front Cell Infect Microbiol 4:160, http://dx.doi.org/10.3389/fcimb.2014.00160 ). In this study, we investigated whether the Agr-mediated response is triggered during adaptation in soil, and we compared survival patterns in a set of 10 soils. The fate of the parental strain L. monocytogenes L9 (a rifampin-resistant mutant of L. monocytogenes EGD-e) and that of a Δ agrA deletion mutant were compared in a collection of 10 soil microcosms. The Δ agrA mutant displayed significantly reduced survival in these b…
How do startups develop internet-of-things systems : a multiple exploratory case study
2019
Internet-of-Things applications are not only the new opportunity for digital businesses but also a major driving force for the modification and creation of software systems in all industries and businesses. Compared to other types of software-intensive products, the development of Internet-of-Things applications lacks a systematic approach and guidelines. This paper aims at understanding the methodological commonalities among startups who are developing Internet-of-Things products. Using the SEMAT Essence framework, we captured common team compositions, common types of Minimum Viable Products and common way of working in early stage Internet-of-Things startups. We found that startups includ…

Dalla Strada della Real Favorita alla Villa Deliella : la misura della qualità nella prima espansione settentrionale di Palermo
2022
Le città, sovente, finiscono per essere identificate con alcune delle proprie componenti salienti; piazze, strade, quartieri, comparti edilizi o interi settori urbani. Nella gamma di profili dei loro abitanti spesso si distinguono coloro i quali appartengono a questi luoghi, in quanto residenti, e quelli che eleggono tali contesti a proprio patrimonio civico, a volte con un maggiore coinvolgimento emotivo. Anche le vedute o i panorami possono spesso attribuire ad una città un valore. Ma proprio per questo sia le variabili delle componenti salienti sia le diverse angolazioni di confronto con il territorio e il paesaggio circostante sono inequivocabilmente soggette alle oscillazioni del senti…

Un sondeig a la via Augusta al terme municipal de la Salzadella (el Baix Maestrat, Castelló)
2016
This paper presents the results of an excavation in the Via Augusta near the town of la Salzadella (Castellón) located between the mansions of Intibili and Ildum. Although the road was partially destroyed in the excavation of a ditch, a section of its eastern half it was discovered.
Las infraestructuras viarias de Saguntum en época imperial: propaganda, prestigio social y poder municipal
2015
During the government of Augustus the city of Sagunto was transformed in a place symbol of modernity. It is no coincidence that the necessary developing infrastructures were consolidated around it for an optimal development: higher quality viae or better port platforms. Different type of streets emerged following an order of importance depending many times on the wealth of their users. Towards the exit of the city burial monuments were placed honoring relevant citizens. As many other major towns of Hispania, Saguntum is not an exception of great transformations.
Potassium uptake system Trk2 is crucial for yeast cell viability during anhydrobiosis
2013
Yeasts grow at very different potassium concentrations, adapting their intracellular cation levels to changes in the external environment. Potassium homeostasis is maintained with the help of several transporters mediating the uptake and efflux of potassium with various affinities and mechanisms. In the model yeast Saccharomyces cerevisiae, two uptake systems, Trk1 and Trk2, are responsible for the accumulation of a relatively high intracellular potassium content (200-300 mM) and the efflux of surplus potassium is mediated by the Tok1 channel and active exporters Ena ATPase and Nha1 cation/proton antiporter. Using a series of deletion mutants, we studied the role of individual potassium tra…
Yeast karyopherins Kap123 and Kap95 are related to the function of the cell integrity pathway
2009
The characterization of mutant strains in the gene encoding karyopherin Kap123 has revealed several morphogenetic defects. Inactivation of KAP123 caused alterations in the actin cytoskeleton, resulting in hyperpolarization and resistance to the actin polymerization inhibitor latrunculin B. In fact, the level of actin filaments is increased in kap123 mutant cells. In addition to the defect in actin cytoskeleton, the kap123 mutant cells showed a weakened cell wall, cell lysis and a growth defect in either the presence of sodium dodecyl sulfate or at high temperatures, which is alleviated by osmotic stabilizers. These defects in cell integrity and the actin cytoskeleton suggested a relationshi…
