Prosthetic Valve Endocarditis with Bartonella washoensis in a Human European Patient and Its Detection in Red Squirrels ( Sciurus vulgaris )
2019
Members of the genus Bartonella are fastidious Gram-negative facultative intracellular bacteria that are typically transmitted by arthropod vectors. Several Bartonella spp. have been found to cause culture-negative endocarditis in humans. Here, we report the case of a 75-year old German woman with prosthetic valve endocarditis due to Bartonella washoensis. The infecting agent was characterized by sequencing of six housekeeping genes (16S rRNA, ftsZ, gltA, groEL, ribC, rpoB) applying a multilocus sequence typing (MLST) approach. The 5097 bp of the concatenated housekeeping gene sequence from the patient were 99.0% identical to a B. washoensis strain from a red squirrel (Sciurus vulgaris orie…
Neisseria gonorrhoeae antimicrobial resistance in Spain: a prospective multicentre study.
2021
Abstract Objectives Gonococcal infection is one of the most reported sexually transmitted infections and antimicrobial resistance in Neisseria gonorrhoeae (NG) is challenging for the treatment of this infection. This observational study aimed to describe antimicrobial resistance of NG and epidemiological data from patients with gonococcal infection in eight regions of Spain, for updating the local therapeutic guidelines. Methods MICs of penicillin, cefixime, ceftriaxone, azithromycin, ciprofloxacin, fosfomycin and gentamicin were determined by Etest for all NG isolates recovered from 1 April 2018 to 30 September 2019 from 10 hospitals in Spain. Resistance determinants were identified using …
Extraordinary stability of hemocyanins from L. polyphemus and E. californicum studied using infrared spectroscopy from 294 to 20 K
2016
International audience; Hemocyanins are large oligomeric respiratory proteins found in many arthropods and molluscs. Here we give infrared spectroscopic evidence of a high stability towards exposure to sub-zero temperatures for hemocyanins from the arthropods Limulus polyphemus and Eurypelma californicum at different pH values. Small but distinct temperature induced changes of the secondary structure were observed, but a stable core of at least 40% α-helical structure is preserved as identified in the infrared spectra obtained between 294 and 20 K. The structural changes differ in detail somewhat for the two hemocyanins, with overall fewer changes observed in the case of E. californicum. No…
The swinholide biosynthesis gene cluster from a terrestrial cyanobacterium, Nostoc sp. strain UHCC 0450
2017
ABSTRACT Swinholides are 42-carbon ring polyketides with a 2-fold axis of symmetry. They are potent cytotoxins that disrupt the actin cytoskeleton. Swinholides were discovered from the marine sponge Theonella sp. and were long suspected to be produced by symbiotic bacteria. Misakinolide, a structural variant of swinholide, was recently demonstrated to be the product of a symbiotic heterotrophic proteobacterium. Here, we report the production of swinholide A by an axenic strain of the terrestrial cyanobacterium Nostoc sp. strain UHCC 0450. We located the 85-kb trans -AT polyketide synthase (PKS) swinholide biosynthesis gene cluster from a draft genome of Nostoc sp. UHCC 0450. The swinholide …
Edición crítica, problemas textuales y de autoría: métrica y ortología en Lope de Vega
2021
Through examples taken from comedies recently attributed to Lope de Vega, this article deals with certain problems that should be considered when studying or editing plays of doubtful authorship. The analysis focuses on methods traditionally used to resolve problematic attributions, such as the study of versification, orthoepy and syllable counting. The conclusion argues that all of these tools —as well as the landmark works by Morley and Bruerton or W. Poesse — still offer great surprises and challenges for researchers. Thus, the development of new methods, such as stylometry, should not impel us to dismiss the classic approaches. Quite the opposite: old and new methods inform one another.
Le soin aux chevaux à l’époque celtique : trousses de vétérinaires et attestation du fer à cheval
2016
Cette communication présente pour l’époque celtique, l’évolution des trousses d’instruments de médecine et une nouvelle preuve de l’usage du fer à cheval dès l’Antiquité. This paper presents, for the Celtic period, the evolution of the doctor’s bag and new proof of the use of the horseshoe as soon as this period.
Abolition de l’esclavage et réorganisation des colonies : les quinze décrets du 27 avril 1848
2022
International audience; L’esclavage a été aboli définitivement en France en 1848, soit plus d’un demi-siècle après la Déclaration des droits de l’homme et du citoyen de 1789, par décrets du Gouvernement provisoire de la IIème République naissante. En effet, le principe de l’abolition immédiate est proclamé dès le 4 mars 1848 par un décret rédigé par Victor Schœlcher rentré en France seulement la veille. Afin de préparer les mesures nécessaires pour en assurer son application, une Commission d’abolition présidée par Schœlcher est instituée. Ses travaux aboutissent à quinze décrets du 27 avril 1848, décrets proclamant l’abolition immédiate de l’esclavage − sans attendre un vote de l’Assemblée…
Antitumor Mechanism of the Essential Oils from Two Succulent Plants in Multidrug Resistance Leukemia Cell
2019
Drug resistance remains a major challenge in the treatment of cancer. The multiplicity of the drug resistance determinants raises the question about the optimal strategies to deal with them. Essential oils showed to inhibit the growth of different tumor cell types. Essential oils contain several chemical classes of compounds whose heterogeneity of active moieties can help prevent the development of drug resistance. In the present paper, we analyzed, by gas chromatography-mass spectrometry the chemical composition of the essential oil of the leaves of Kalanchoe beharensis obtained by hydrodistillation and compared the chemical composition of its essential oil with that of Cyphostemma juttae.…
Soccer players' fitting perception of different upper boot materials.
2016
[EN] The present study assessed the influence of upper boot materials on fitting perception. Twenty players tested three soccer boots only differing in the upper boot material (natural calf leather, natural kangaroo leather and synthetic leather). Players reported fitting perception and preference on specific foot areas using a perceived fitting scale. Ratings were averaged for every foot area. Repeated measures ANOVA was used to analyze the differences between boots. The kangaroo leather boots were perceived tighter and closer to the preferred fitting in general fitting, metatarsals area and instep area. The synthetic leather boots were perceived as the loosest and as the most distant boot…
A Study of Maternal Competence in Preterm Birth Condition, during the Transition from Hospital to Home: An Early Intervention Program’s Proposal
2021
The study was conducted with 104 mothers (average age 32.5 years, SD 6.1) of preterm infants (very and moderately preterm but still healthy) to monitor the perceived maternal role competence from the time of hospitalisation to post-discharge, in order to define an intervention program to support mothers during this transition. A targeted Q-Sort tool (Maternal Competence Q-Sort in preterm birth) was applied at two different times as a self-observation tool for parenting competence in neonatology. A tendency towards dysregulation of the maternal role competence was detected, mainly in terms of low self-assessment and was found to worsen during post-discharge, particularly with regard to careg…
