Vibrio vulnificus biotype 2, pathogenic for eels, is also an opportunistic pathogen for humans

1996

We report that the eel pathogen Vibrio vulnificus biotype 2 is also an opportunistic pathogen for humans. Results from a detailed comparative study using reference strains of both biotypes revealed that the clinical strain ATCC 33817, originally isolated from a human leg wound and classified as V. vulnificus (no reference on its biotype is noted), belongs to biotype 2 of the species. As a biotype 2 strain, it is negative for indole and pathogenic for eels and mice, harbors two plasmids of high MrS, and belongs to serogroup E, recently proposed as characteristic of biotype 2 strains. In consequence, appropriate measures must be taken by consumers, particularly by those running a health risk,…

Fat storing cells (FSC) of rat liver synthesize and secrete fibronectin

1987

Summary Fat storing cells (FSC) of rat liver were isolated and kept in culture for up to 2 weeks. Freshly isolated cells and cells in culture were characterized functionally (vitamin A content) and morphologically. Their synthetic capacity for fibronectin was studied quantitatively by ELISA-measurement and qualitatively by biosynthetic labeling, immunoprecipitation and SDS-PAGE analysis. The synthesis product and the kinetics of the synthesis and secretion were compared with those obtained from culture of hepatocytes. FSC were shown to synthesize and secrete fibronectin under the culture conditions used. No fibronectin synthesis was detected during the first 3 days of culture. Thereafter th…

La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo

2023

Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…

Within this framework Palermo and its historic center are no exception. The epicenter of these processes is represented here by the Kalsa district which since the early 2000s has been placed at the center of a precise strategy of culturally-based renewal called to drive the city's tourist renaissance (Vinci 2008). The culmination of this path came in 2018 when Palermo was named the Italian capital of culture and chosen as the venue for Manifesta one of the most prestigious traveling biennales of contemporary art. However the exponential increase in tourist arrivals in the last three years came to a halt with the outbreak of the pandemic which showed with unprecedented evidence the contradictions of the development strategies pursued in the historic center and the marks they leave on the territories. While this sudden interruption seems to offer an opportunity to radically rethink urban and cultural policies and find new curbs to the conditions of overtourism in which the historic centers of South European cities and beyond find themselves it could also prove to be an accelerator of the dynamics of commodification of these spaces representing the revival of tourism an easy escape route in times of crisis. The objective of this contribution is to critically explore the urban and social transformations that have crossed the Kalsa district of Palermo from the 2000s to the present using qualitative and quantitative techniques (analysis of statistical data in-depth interviews critical discourse analysis ...) with particular reference to the role that culture has played in these processes. While it is impossible to prefigure post-pandemic scenarios we will examine documents and discourses that trace possible development directions for South European cities and their historic centers.Settore ICAR/21 - UrbanisticaSettore M-GGR/01 - Geografia

Identification of hexanuclear Actinide(IV) carboxylates with Thorium, Uranium and Neptunium by EXAFS spectroscopy

2012

International audience; Hydrated actinide(IV) ions undergo hydrolysis and further polymerization and precipitation with increasing pH. The resulting amorphous and partly crystalline oxydydroxides AnO(n)(OH)(4-2n)center dot xH(2)O can usually be observed as colloids above the An(IV) solubility limit. The aging process of such colloids results in crystalline AnO(2). The presence of carboxylates in the solution prevents the occurrence of such colloids by formation of polynuclear complexes through a competing reaction between hydrolysis and ligation. The majority of recently described carboxylates reveals a hexanuclear core of [An(6)(mu(3)-O)(4)(mu(3)-OH)(4)](12+) terminated by 12 carboxylate l…

Phylogeographical footprints of the Strait of Gibraltar and Quaternary climatic fluctuations in the western Mediterranean: a case study with the grea…

2005

Correspondance: cosson@supagro.inra.fr; International audience; We used mitochondrial cyt b sequences to investigate the phylogenetic relationships of Crocidura russula (sensu lato) populations across the Strait of Gibraltar, western Europe, Maghreb, and the Mediterranean and Atlantic islands. This revealed very low genetic divergence between European and Moroccan populations. The application of a molecular clock previously calibrated for shrews suggested that the separation of European from Moroccan lineages occurred less than 60 000 bp, which is at least 5 million years (Myr) after the reopening of the Strait of Gibraltar. This means that an overwater dispersal event was responsible for t…

[Norovirus infections: an overview]

2010

National audience; Noroviruses belong to the Caliciviridae family. They are a major cause of sporadic cases and outbreaks of gastroenteritis in all age groups, and are responsible for a considerable disease burden in industrialized countries. Noroviruses are single-stranded RNA viruses, and show great genetic diversity making their detection difficult. Noroviruses can be divided into 5 genogroups, which themselves are subdivided into genotypes. Besides chance mutations that occur during viral replication, the great heterogeneity observed among noroviruses is also due to intra and inter-genotypic recombination events between strains. Some of these new variants or new recombinants are frequen…

Effect of growing area on tocopherols, carotenoids and fatty acid composition ofPistacia lentiscusedible oil

2014

International audience; In this investigation, we aim to study, for the first time, the effect of the growing area on tocopherols, carotenoids and fatty acid content of Pistacia lentiscus fixed oil. Fruits were harvested from eight different sites located in the north and the centre of Tunisia. Tocopherols, carotenoids and fatty acid content of the fixed oils were determined. The highest carotenoid content was exhibited by Feija oil (10.57 mg/kg of oil). Oueslatia and Tabarka oils displayed the highest alpha-tocopherol content (96.79 and 92.79 mg/kg of oil, respectively). Three major fatty acids were determined: oleic, palmitic and linoleic acids. Oleic acid was the main fatty acid presenti…
