Comparative evaluation of molecular methods for the quantitative measure of torquetenovirus (TTV) viremia, the new surrogate marker of immune compete…
2019
Background Torquetenovirus (TTV) viremia is emerging as a promising tool to assess functional immune competence, to predict posttransplant immune-related complications, and eventually to customize immunosuppression. Methods In this study, 327 blood samples were tested using two real-time PCR (rtPCR) assays both targeted to the untranslated region of the TTV genome. The first assay was an in-house rtPCR developed by our group, the second one was the recently marketed TTV R-GENE assay. Results In the validation study, the TTV R-GENE showed good performances in precision and reproducibility, and sensitivity as low as 12 TTV DNA copies/mL, like previously reported for the in-house rtPCR. The Bl…
Characterization of the LGBTI-speaking community discourse. An approach to Hispanic queer linguistics.
2020
Toda subcultura forma una comunidad lingüística particular en la que, aunque se comparta la lengua con el resto de la sociedad, varía el habla en ciertos aspectos. Es el caso de la comunidad de habla LGTBI, que se hace servir de un léxico peculiar, así como una fraseología característica, unas estructuras gramaticales especiales y, en definitiva, unos recursos pragmáticos muy llamativos que tienen como objetivo mitigar ciertos enunciados, intensificar otros en determinados contextos y construir actos de habla afiliativos que expresen solidaridad social. Por otro lado, cumple una función muy importante en la construcción identitaria de sus usuarios. En este trabajo se propone un análisis pra…
How physical parameterizations can modulate internal variability in a regional climate model
2012
Abstract The authors analyze to what extent the internal variability simulated by a regional climate model is sensitive to its physical parameterizations. The influence of two convection schemes is quantified over southern Africa, where convective rainfall predominates. Internal variability is much larger with the Kain–Fritsch scheme than for the Grell–Dévényi scheme at the seasonal, intraseasonal, and daily time scales, and from the regional to the local (grid point) spatial scales. Phenomenological analyses reveal that the core (periphery) of the rain-bearing systems tends to be highly (weakly) reproducible, showing that it is their morphological features that induce the largest internal …
Platinum chloride-based viability RT-qPCR for SARS-CoV-2 detection in complex samples.
2021
Isolation, contact tracing and restrictions on social movement are being globally implemented to prevent and control onward spread of SARS-CoV-2, even though the infection risk modelled on RNA detection by RT-qPCR remains biased as viral shedding and infectivity are not discerned. Thus, we aimed to develop a rapid viability RT-qPCR procedure to infer SARS-CoV-2 infectivity in clinical specimens and environmental samples. We screened monoazide dyes and platinum compounds as viability molecular markers on five SARS-CoV-2 RNA targets. A platinum chloride-based viability RT-qPCR was then optimized using genomic RNA, and inactivated SARS-CoV-2 particles inoculated in buffer, stool, and urine. Ou…
La comparaison de corpus parallèles / comparables pour l’approche des macrostructures : les discours de conjoncture économique
2017
National audience; La présentation vise à discuter, à partir du cas des discours de conjoncture économique (BCE, banques centrales "nationales", instituts de conjoncture) l'apport croisé potentiel des corpus comparables et parallèles pour produire des ressources mobilisables pour le traducteur financier professionnel.
Multicomponent Exercise Training Combined with Nutritional Counselling Improves Physical Function, Biochemical and Anthropometric Profiles in Obese C…
2020
Aerobics or strength exercise plus diet interventions have been shown to counteract childhood obesity. However, little is known with regard to periodized multicomponent exercise interventions combined with nutritional counselling, which might be less demanding but more enjoyable and respectful of children and adolescents&rsquo
MICRODISSECTION AND DOP-PCR-BASED REVERSE CHROMOSOME PAINTING AS A FAST AND RELIABLE STRATEGY IN THE ANALYSIS OF VARIOUS STRUCTURAL CHROMOSOME ABNORM…
1996
Reverse chromosome painting has become a powerful tool in clinical genetics for the characterization of cytogenetically unclassifiable aberrations. In this report, the application of a sensitive and rapid procedure for the complete and precise identification of four different de novo structural chromosome abnormalities is presented. These chromosome rearrangements include a marker derived from chromosome 3(cen-q11), an interstitial deletion of chromosome 13 [del(13)(q14q22)], an unbalanced translocation [46,XY, -4, +der(4)t(4;8)(p 15.2;p21.1)] leading to Wolf-Hirschhorn syndrome, and a partial inverted duplication in conjunction with a partial deletion of chromosome 5p [46,XX, -5, +der(5)(:…
P046 Vitamin D decreases PDIA3 and prevents the enhanced migration of fibroblasts from stricturing Crohn’s disease
2020
Abstract Background Fibrosis is a common complication in Crohn’s disease (CD) patients and fibroblasts play an important role in the fibrogenic process. Low vitamin D (VD) levels and a defective VD-signalling pathway have been reported in CD. VD signals through both vitamin D receptor (VDR) and protein disulfide-isomerase A3 (PDIA3) and we have previously demonstrated that VDR protein levels are reduced in fibroblasts isolated from CD patients and that VD increased VDR expression in these cells (A-2080; ECCO 2019). We aim to analyse here the effect of VD on both PDIA3 protein levels and migration in CD fibroblasts. Methods We used intestinal fibroblasts isolated from surgical resections of …
OP20 Risk and predictors of surgery in a newly diagnosed cohort of IBD patients in the biologic era: Results from the EpidemIBD study
2021
Abstract Background The management of inflammatory bowel disease (IBD) has substantially changed in the last decades, both in relation to medical and surgical treatments. Aims Principal: To know the rate of surgery in a newly diagnosed IBD cohort within the first year after diagnosis. Secondary: To describe the type of surgeries and indications in this cohort, and to identify predictive factors for surgery (focused on intestinal resection) in these patients. Methods Prospective, population-based nationwide registry. Adult patients diagnosed with IBD -Crohn’s disease (CD) and ulcerative colitis (UC)- during 2017 in Spain were included and were followed-up for 1 year. Kaplan-Meier curves were…
Effects of SCA40 on human isolated bronchus and human polymorphonuclear leukocytes: comparison with rolipram, SKF94120 and levcromakalim
1996
1. SCA40 (0.1 nM-0.1 mM) produced concentration-dependent suppression of the spontaneous tone of human isolated bronchus (-log EC50 = 6.85 +/- 0.09; n = 10) and reached a maximal relaxation similar to that of theophylline (3 mM). The potency (-log EC50 values) of SCA40 compared to other relaxants was rolipram (7.44 +/- 0.12; n = 9) > SCA40 > or = levcromakalim (6.49 +/- 0.04; n = 6) > SKF94120 (5.87 +/- 0.10; n = 9). 2. When tested against the activity of the isoenzymes of cyclic nucleotide phosphodiesterase (PDE) isolated from human bronchus, SCA40 proved highly potent against PDE III (-log IC50 = 6.47 +/- 0.16; n = 4). It was markedly less potent against PDE IV (4.82 +/- 0.18; n = 4) and …
