A modified dinucleotide motif specifies tRNA recognition by TLR7
2014
RNA can function as a pathogen-associated molecular pattern (PAMP) whose recognition by the innate immune system alerts the body to an impending microbial infection. The recognition of tRNA as either self or nonself RNA by TLR7 depends on its modification patterns. In particular, it is known that the presence of a ribose methylated guanosine at position 18, which is overrepresented in self-RNA, antagonizes an immune response. Here, we report that recognition extends to the next downstream nucleotide and the effectively recognized molecular detail is actually a methylated dinucleotide. The most efficient nucleobases combination of this motif includes two purines, while pyrimidines diminish t…
Importance of sarcopenia parameter changes after living donor liver transplantation
2017
The systemic role of muscle tissue is strengthened by the large system of hormones, chemokines and other mediators that constitute a dense network of communication between the skeletal muscle and the liver (1,2). This, associated with the evidence of a progressive malnutrition and depletion of muscle mass in end-stage liver disease (ESLD) patients, has led many to study the role of sarcopenia and its systemic effects in this setting, and to identify it as critical risk factor for post- liver transplantation (LT) mortality (3-5). Englesbe and colleagues found a direct correlation between central sarcopenia, measured by computerized tomography (CT), the total area of the psoas muscle (psoas a…
Plasmid-mediated QnrS2 determinant from a clinical Aeromonas veronii isolate.
2008
The main objective of this study was to determine the prevalence of the Qnr determinants in clinical and environmental Aeromonas spp. A total of 52 Aeromonas sp. isolates identified by biochemical methods (5), 25 isolated from natural waters (1) and 27 isolated from clinical samples from hospitals in Valencia, Spain, were tested for quinolone resistance by the disk diffusion method (4) (nalidixic acid, 30 μg; oxolinic acid, 2 μg; flumequine, 30 μg; ciprofloxacin, 5 μg; and levofloxacin, 5 μg). Among the studied isolates, 27 showed resistance to nalidixic acid and susceptibility to ciprofloxacin, 24 isolates were susceptible to both nalidixic acid and ciprofloxacin, and only 1, the A. veroni…
Fumador, exfumador y COVID-19: la nicotina no protege contra el SARS-CoV-2
2021
Queremos agradecer a Moril et al.1 el interés en nuestro trabajo, pues nos permite reflexionar sobre el tema. La proteína Spike del SARS-CoV-2 es la responsable de facilitar su entrada a las células humanas, requiriendo cebado por la proteasa TMPRSS2 que permite la fusión de las membranas viral y celular2. El receptor utilizado por la proteína Spike es la enzima convertidora de angiotensina 2 (ACE2)2, que se expresa en diferentes estirpes celulares, además de en el pulmón; existiendo, a nivel pulmonar, un gradiente de expresión de ACE2 (mayor expresión en vías respiratorias superiores [epitelio nasal] y menor en los neumocitos alveolares)2. Se sugiere que una mayor expresión de ACE2 podría …
El valencianisme lingüístic de Nicolau Primitiu Gómez Serrano
2012
Aquest article constitueix un estudi de les activitats més rellevants i la posició ideològica de Nicolau Primitiu Gómez Serrano al voltant del català de València: fixació de la toponímia del País Valencià, defensa i difusió de les Normes de Castelló, reivindicació de l’ús del valencià a l’escola i del seu ensenyament, promoció del Diccionari Català-Valencià-Balear d’Alcover-Moll, creació de plataformes editorials i teories sobre l’origen i el nom de la llengua dels valencians.
Editorial decisions: highlighting the role of systematic reviews
2018
En 2014, el doctor Gerard Urrútia del Centro Cochrane Iberoamericano - Institut d'Investigació Biomèdica Sant Pau, escribió unas líneas editoriales para la Revista Española de Nutrición Humana y Dietética1 en las que ponía en valor la necesidad de "incrementar el rigor científico tanto en la producción de estudios científicos, que proporcionen las bases para una toma de decisiones bien fundamentada, como en su divulgación mediante publicaciones científicas de calidad" en el ámbito de la nutrición y la dietética. Asimismo vaticinaba que "cabría esperar, por una parte, un creciente interés en la producción de revisiones sistemáticas por parte de profesionales de nuestro medio, también entre d…

Letter to the Editor regarding the paper by Aurilio et al., A meta-analysis of oestrogen receptor, progesterone receptor and human epidermal growth f…
2014
Sir,We have read with great interest the article in press ofAurilio et al., A meta-analysis of oestrogen receptor, pro-gesterone receptor and human epidermal growth factorreceptor 2 discordance between primary breast cancerand metastases (http://dx.doi.org/10.1016/j.ejca.2003.10.004), which will appear in Eur J Cancer. In the paper,the Authors have performed a meta-analysis of the stud-ies published in the literature concerning the discor-dance rate in oestrogen receptor (ER), progesteronereceptor (PgR) and HER2 status between primarytumour and corresponding relapse. It is well known thata considerable controversy concerns the issue of hor-mone receptors (HRs) expression as well as HER2 sta…
