Effects of a massage protocol in tensiomyographic and myotonometric proprieties

Background: Pre-competition massage is usually used to improve athletic performance and reduce risk of injury. Despite its usual use, the effects of pre-competition massage on neuromuscular function have barely been studied. The aim of this study is to evaluate the effects of the pre-competition massage over the gastrocnemius neuromuscular function. Method: The study is a quasi-experimental clinical trial thirty healthy athletes were enrolled in the study. Subjects received an intervention in one leg (experimental), consisting of a massage, and no intervention in the opposite leg (control). From all values of neuromuscular function, the following were analyzed: contraction time (Tc) and maximal displacement (Dm) by tensiomyography, and stiffness and tone by myotonometry. Results: Main effects of pre-competition massage on neuromuscular function include a significant (p < 0.05) increase in Tc and Dm variables, as well as a reduction in stiffness and tone. Conclusion: Data shows an increase in Tc and maximal radial displacement (Dm) variables, as well as a reduction in stiffness and tone. More quality studies are needed to draw clear conclusions about the effects of pre-competition massage. © 2021 by the authors. Licensee MDPI, Basel, Switzerland

Phenotypic and genotypic characterization of imipenem-resistant Pseudomonas aeruginosa isolated in Buenos Aires

En el presente estudio, que tuvo por objeto analizar los mecanismos involucrados en la resistencia a carbapenemes, se incluyeron 129 aislamientos de Pseudomonas aeruginosa recuperados durante el año 2006 en el Hospital “Eva Perón” de la Provincia de Buenos Aires. La caracterización fenotípica y genotípica de la resistencia permitió reconocer la presencia de metalo-β-lactamasas (MBL) en el 14% de esos aislamientos. En todos ellos se identificó la presencia de la enzima IMP-13; sin embargo, algunos aislamientos resultaron sensibles a carbapenemes de acuerdo a los puntos de corte establecidos por el CLSI e incluso a las sugerencias de la Subcomisión de Antimicrobianos de SADEBAC, AAM. El ensayo de detección fenotípica de MBL de sinergia con doble disco resultó útil en este estudio. Sólo aquellos aislamientos productores de IMP-13 que a su vez presentaron alteraciones en las proteínas de membrana externa resultaron completamente resistentes a imipenem. Los aislamientos productores de MBL correspondieron a varios tipos clonales, lo cual sugiere no sólo la diseminación de una cepa resistente, sino también la diseminación horizontal de este mecanismo de resistencia entre clones diferentesrom 129 P. aeruginosa isolated at a health care centre located in Buenos Aires (Hospital “Eva Perón”), 14% produced IMP-13. Although 18 isolates were metallo-β-lactamases (MBL) producers, only those isolates that displayed altered outer membrane protein profiles correlated with the resistant category according to CLSI or even Subcomisión de Antimicrobianos, SADEBAC, AAM. Phenotypic screening of metallo-β-lactamases proved to be appropriate for detecting MBL producing isolates. IMP-13 producing isolates corresponded to at least five different clonal types, which not only suggests the dissemination of the resistant strain but also of the resistant marker.Fil: Cejas, D..

Quantitative trait loci analysis of a Duroc commercial population highlights differences in the genetic determination of meat quality traits at two different muscles

We performed a whole-genome scan with 110 informative microsatellites in a commercial Duroc population for which growth, fatness, carcass and meat quality phenotypes were available. Importantly, meat quality traits were recorded in two different muscles, that is, gluteus medius (GM) and longissimus thoracis et lumborum (LTL), to find out whether these traits are determined by muscle-specific genetic factors. At the whole-population level, three genome-wide QTL were identified for carcass weight (SSC7, 60 cM), meat redness (SSC13, 84 cM) and yellowness (SSC15, 108 cM). Within-family analyses allowed us to detect genome-wide significant QTL for muscle loin depth between the 3rd and 4th ribs (SSC15, 54 cM), backfat thickness (BFT) in vivo (SSC10, 58 cM), ham weight (SSC9, 69 cM), carcass weight (SSC7, 60 cM; SSC9, 68 cM), BFT on the last rib (SSC11, 48 cM) and GM redness (SSC8, 85 cM; SSC13, 84 cM). Interestingly, there was low positional concordance between meat quality QTL maps obtained for GM and LTL. As a matter of fact, the three genome-wide significant QTL for colour traits (SSC8, SSC13 and SSC15) that we detected in our study were all GM specific. This result suggests that QTL effects might be modulated to a certain extent by genetic and environmental factors linked to muscle function and anatomical location. © 2012 The Authors, Animal Genetics © 2012 Stichting International Foundation for Animal Genetics.This study was funded with grants AGL2002-04271-C03 and AGL2007-66707-C02-01 (Ministerio de Ciencia e Innovación, Spain).Peer Reviewe

Jornada de Innovación Docente de la Universidad de Valladolid: Los Universos Docentes (6º. 2016. Valladolid)

Producción CientíficaLos nuevos profesores-tutores desempeñan competencias que incluyen el uso de las TICs, el diseño de Objetos de Aprendizaje Multimedia (OAM) y la supervisión del aprendizaje del alumnado. En este contexto, Inmunomedia 4.0 –proyecto en el que participan las Universidades de Valladolid, Alicante, Complutense y Toulouse III- restá respondiendo a las necesidades y carencias en la docencia de la Inmunología en titulaciones Biomédicas: en primer lugar “Elaborando y difundiendo OAMs" de Inmunología de calidad, como la colección de “Inmunopíldoras” de gran impacto entre universitarios hispanoparlantes; en segundo lugar "Coleccionando OAMs en tablones" (“Content Curation”) que proporcionan a estudiantes y profesores información útil, etiquetada, contrastada y organizada por Módulos. De las diferentes herramientas de “content curation” utilizadas, las de mayor repercusión han sido las colecciones realizadas con “Scoop.it” y “Pinterest”; en tercer lugar "Implicando activamente a los estudiantes" de diferentes universidades en la elaboración de un “Periódico Universitario de Inmunología” tras emitir en twitter noticias de interés inmunológico usando hashtags, que se rastrean y generan un diario en “Paper.li”; y finalmente "Impulsando la tercera misión universitaria" elaborando materiales divulgativos multimedia de inmunología y difundiéndolos en redes sociales, a los pacientes e incluso en lugares públicos (colección de videos “Canal Defensas”)

Unusual presentations of Comamonas kerstersii infection

The association of Comamonas kerstersii with peritonitis resulting from the presence of perforated appendix has previously been described by our research team. In the present study, we describe the isolation of this microorganism from two forms of unusual presentations of C. kerstersii infection not previously described in the literature: localized intra-abdominal infection (psoas abscess) and pelvic peritonitis
