Carbapenem-Susceptible OXA-23-Producing Proteus mirabilis in the French Community

2019

International audience; Nineteen Proteus mirabilis isolates producing the carbapenemase OXA-23 were recovered over a 2-year period in 19 French hospitalized patients, of whom 12 had community onset infections. The isolates exhibited a slightly reduced susceptibility to carbapenems. Whole-genome analysis revealed that all 19 isolates formed a cluster compared to 149 other P. mirabilis isolates. Because of its susceptibility to carbapenems, this clone may be misidentified as a penicillinase producer while it constitutes a reservoir of the OXA-23-encoding gene in the community.

High level of intrinsic phenotypic antimicrobial resistance in enterobacteria from terrestrial wildlife in Gabonese national parks.

2021

Data on the prevalence of antibiotic resistance in Enterobacteriaceae in African wildlife are still relatively limited. The aim of this study was to estimate the prevalence of phenotypic intrinsic and acquired antimicrobial resistance of enterobacteria from several species of terrestrial wild mammals in national parks of Gabon. Colony culture and isolation were done using MacConkey agar. Isolates were identified using the VITEK 2 and MALDI-TOF methods. Antibiotic susceptibility was analysed and interpreted according to the European Committee on Antimicrobial Susceptibility Testing guidelines. The preliminary test for ESBL-producing Enterobacteriaceae was performed by replicating enterobacte…

Novel Lipid and Polymeric Materials as Delivery Systems for Nucleic Acid Based Drugs

2015

Nucleic acid based drugs (NADBs) are short DNA/RNA molecules that include among others, antisense oligonucleotides, aptamers, small interfering RNAs and micro-interfering RNAs. Despite the different mechanisms of actions, NABDs have the ability to combat the effects of pathological gene expression in many experimental systems. Thus, nowadays, NABDs are considered to have a great therapeutic potential, possibly superior to that of available drugs. Unfortunately, however, the lack of effective delivery systems limits the practical use of NABDs. Due to their hydrophilic nature, NABDs cannot efficiently cross cellular membrane; in addition, they are subjected to fast degradation by cellular and…

Study of the flying geese theory from a political point of view : a Japanese propaganda argument in the post world war II era

2009

The Flying Geese Theory (gankoo keitai hattenron 雁行形態発展論), dating from 1932, is one of the rare cases of a scientific theory that was used as a part of Japanese wartime propaganda, and which also survived and succeeded in the postwar era. It was used to legitimize the 'New Order in East Asia (TōA shinchitsujo 東亜新秩序) in 1938, and the new formulation of the 'Greater East Asia Co-Prosperity Sphere‘ (Dai TōA kyōeiken大東亜共栄圏) in 1940. Later in the 1980s the Flying Geese Theory/Pattern became the most successful candidate for explaining the expansion of ‗Asian economical miracles‘ in the postwar era. This study focuses on this famous piece of economical and political rhetoric. The intention is to …

Alterations in Circulating miRNA Levels following Early-Stage Estrogen Receptor-Positive Breast Cancer Resection in Post-Menopausal Women

2014

INTRODUCTION: Circulating microRNAs (miRNAs) exhibit remarkable stability and may serve as biomarkers in several clinical cancer settings. The aim of this study was to investigate changes in the levels of specific circulating miRNA following breast cancer surgery and evaluate whether these alterations were also observed in an independent data set.METHODS: Global miRNA analysis was performed on prospectively collected serum samples from 24 post-menopausal women with estrogen receptor-positive early-stage breast cancer before surgery and 3 weeks after tumor resection using global LNA-based quantitative real-time PCR (qPCR).RESULTS: Numbers of specific miRNAs detected in the samples ranged fro…

The Potential Role of miRNAs in Cognitive Frailty.

2021

Frailty is an aging related condition, which has been defined as a state of enhanced vulnerability to stressors, leading to a limited capacity to meet homeostatic demands. Cognitive impairment is also frequent in older people, often accompanying frailty. Age is the main independent risk factor for both frailty and cognitive impairment, and compelling evidence suggests that similar age-associated mechanisms could underlie both clinical conditions. Accordingly, it has been suggested that frailty and cognitive impairment share common pathways, and some authors proposed “cognitive frailty” as a single complex phenotype. Nevertheless, so far, no clear common underlying pathways have been discove…

Rewriting antiquity, renewing Rome. The Identity of the Eternal City through Visual Art, Monumental Inscriptions and the Mirabilia

2011

AbstractDuring the eleventh and twelfth centuries the Church began a process of renovation (renovatio) and the city of Rome was given new meanings. Antiquity is part of the identity of the Eternal City; the reuse or reframing of aspects of antiquity inevitably transformed the image of Rome. Public spaces, architecture and objects were given new Christian readings. Inscriptions, present both in sacred and secular settings, played an important role. A similar rewriting can also be found in travel literature and descriptions of the city, such as in the Mirabilia urbis Rome, where ancient monuments were re-interpreted to demonstrate the superiority of Christianity. Inscriptions were used as sym…
