ABSTRACT To determine the occurrence of carbapenem-resistant Acinetobacter baumannii in fish fished from Mediterranean Sea near Bejaia coast (Algeria), we studied 300 gills and gut samples that had been randomly prospectively collected during 1 year. After screening on selective agar media, using PCR arrays whole-genome sequencing, identified for first time two OXA-23-producing A. strains belonging to widespread sequence type 2 (ST2)/international clone II harboring aminoglycoside-modifying...
In Saccharomyces cerevisiae, the oxidative stress-activated zinc cluster protein Stb5p activates genes involved in NADPH production and most of pentose phosphate (PP) pathway. To gain insight into role Stb5p, we studied behaviour stb5 deletion mutants during aerobic anaerobic growth on glucose. were auxotrophic for methionine pyrimidine nucleotides. The auxotrophy phenotype was air dependent, suggesting an impaired status. Consistent with this, acetate level reduced α-ketoglutarate increased...
Saccharomyces cerevisiae strains lacking phosphoglucose isomerase (pgi1) cannot use the pentose phosphate (PP) pathway to oxidize glucose, which has been explained by lack of mechanism for reoxidation NADPH surplus. Consistent with this, defective growth on glucose a ENYpgi1 strain can be partially restored expressing Escherichia coli transhydrogenase udhA. In this work it was found that V5 (wine yeast-derived) and FY1679 (isogenic S288C) pgi1 mutants is not rescued expression Moreover, flux...
For the analysis of volatile bacterial compounds, solid phase microextraction (SPME) is currently most widely used metabolite concentration technique. Recently, potential stir bar sorptive extraction (SBSE) for this use has been demonstrated. These two approaches were therefore in combination with gas-chromatography coupled mass-spectrometry (GC–MS) and semi-volatile compounds produced by Staphylococcus aureus. In both cases, SPME SBSE/headspace (HSSE) enrichment was carried out coating...
Background Airtankers are able to drop volumes of liquid (suppressant or fire retardant) varying from less than 1 m3 several tens cubic metres directly on a with the objective form barriers retardant stop reduce propagation. Aims The this work is demonstrate that Computational Fluid Dynamics can be used provide deep understanding fragmentation and dispersion when dropped an aircraft. Methods A numerical investigation based Volume method for analysis airtanker performance applied here biggest...
We performed a dynamic and quantitative analysis of the synthesis fermentative aromas by an aromatic wine yeast, ECA5, obtained adaptive evolution. During fermentation at pilot scale on synthetic natural musts, ECA5 produced volatile compounds (higher alcohols their acetates, ethyl esters) higher rates than ancestral strain, with exception propanol. Marked differences in chronology several were observed between two strains. Overproduction phenyl ethanol occurred mainly during growth phase...
Tabletop Role-Playing Games (TRPGs) for disaster response management are collaborative exercises in which participants take on the roles of characters, guided by a “Game Master.” TRPG useful tools training, improving preparedness emergency responders, and understanding/validating Agent-Based Models (ABMs). This study evaluates knowledge assessed effectiveness utilizing validating NetLogo model. Medical doctors master’s students were divided into two groups, who participated exercise based...
Aims Virus detection has often been difficult due to a low concentration in water. In this study, we developed new procedure based on of virus particles an innovative support: poly-l-lysine dendrigrafts (DGL), coupled with directed nucleic acid extraction and real-time PCR quantification. Methods Results This method was evaluated using the bacteriophage MS2 as model virus. exhibited size structural properties human pathogenic enteric viruses used assess supports concentration. Moreover, is...
There are several analytical procedures available for the monitoring of volatile organic compounds (VOCs) in air, which differ mainly on sampling procedures. The Coriolis micro air sampler is a tool normally designed biological sampling. In this paper, bio collector used to evaluate its ability sample contaminants and detecting them when combined GC-MS. We also compare use with standardized method, lung box Nalophan® bag. results show that method suitable contaminants. Indeed, allows detect...
Aim: We evaluated the performance of Unyvero implant and tissue infections system (ITI) application (Curetis) to diagnose Diabetic Foot Osteomyelitis (DFOM). Patients & methods: The study was conducted in reference center Nîmes University Hospital (France) from 1 December 2016 31 May 2017. compared ITI PCR conventional culture alternative molecular approaches. Results: A total 79 patients with DFOM were included: 177 microorganisms isolated by culture, 146 detected PCR, resulting a...

<title>Abstract</title> Mean wait time (MWT) in emergency departments refer to the average patients spend undergoing evaluation, or treatment at each stage, which can be significantly affected by sudden onsets of a disaster. Agent-based modeling (ABM) is computational technique that simulates interactions and behaviors individual agents defined environment enables study complex systems observing emergent outcomes agent-agent agent-environment interactions. This examines capability ABMs...
