Aspectes de la transitivitat en els inicis del català modern
2019
En aquest estudi de corpus hem volgut fer una primera aproximació a diversos aspectes de la transitivitat, entesa com a fenomen amb diversos vessants, en els textos corresponents a l’inici del català modern (segle XVII, amb un èmfasi especial en la primera meitat de segle). Hem tractat, concretament, el cas de diversos verbs que presenten un comportament vacil·lant entre l’ús transitiu i l’ús intransitiu, i ens hem acostat a aquest fenomen des del vessant del marcatge diferencial d’objecte, atès que aquest règim vacil·lant és un factor que pot crear confusió a l’hora d’analitzar l’extensió dels objectes directes introduïts per a (v. § 2). A continuació, i encara mantenint el marcatge difere…

El valor del establecimiento y su relación con la imagen de marca privada: efecto moderador del conocimiento de la marca privada como oferta propia d…
2013
ResumenEl presente trabajo plantea como objetivo conocer cómo afecta la imagen de marca privada a la formación del valor de marca del establecimiento; en el estudio de esta relación cobra especial consideración la posible influencia del conocimiento de la marca privada como oferta propia del establecimiento. Desde una perspectiva empírica, se analizan los establecimientos Decathlon, a partir de la opinión de 300 consumidores. Los resultados obtenidos en la investigación muestran la importancia de fortalecer una imagen de marca privada positiva y favorable, como medio para la construcción de una sólida imagen de la tienda que, a su vez, también repercute en la creación del valor del establec…
Expression inactivation of SMARCA4 by microRNAs in lung tumors
2014
SMARCA4 is the catalytic subunit of the SWI/SNF chromatin-remodeling complex, which alters the interactions between DNA and histones and modifies the availability of the DNA for transcription. The latest deep sequencing of tumor genomes has reinforced the important and ubiquitous tumor suppressor role of the SWI/SNF complex in cancer. However, although SWI/SNF complex plays a key role in gene expression, the regulation of this complex itself is poorly understood. Significantly, an understanding of the regulation of SMARCA4 expression has gained in importance due to recent proposals incorporating it in therapeutic strategies that use synthetic lethal interactions between SMARCA4-MAX and SMAR…

Genetic systems for a new approach to risk of progression of diabetic retinopathy.
2016
OBJECTIVE: To evaluate the risk of progression of diabetic retinopathy (DR) using new strategies to obtain genetic information in type 2 diabetes (T2D) based on interfering ribonucleic acid (RNA). MATERIAL AND METHODS: A prospective multicentre case-control study of 132 participants was distributed into: T2D with (+DR) or without (-DR) (T2DG; n=77), and a control group (CG; n=55). After an eye examination and personal interview, tears were collected for molecular analysis (expression of microRNAs [miRNAs] (miRCURY ARN Isolation Kit, Qiagen)]. Libraries, 137 vs. 140bp (GeneMapper, Applied Biosystems), were obtained in 18 samples (T2DG+DR=6; T2DG-DR=6; CG=6) by performing next-generation sequ…
Non-targeted metabolomic biomarkers and metabotypes of type 2 diabetes: A cross-sectional study of PREDIMED trial participants
2019
Aim. - To characterize the urinary metabolomic fingerprint and multi-metabolite signature associated with type 2 diabetes (T2D), and to classify the population into metabotypes related to T2D. Methods. - A metabolomics analysis using the 1 H-NMR-based, non-targeted metabolomic approach was conducted to determine the urinary metabolomic fingerprint of T2D compared with non-T2D participants in the PREDIMED trial. The discriminant metabolite fingerprint was subjected to logistic regression analysis and ROC analyses to establish and to assess the multi-metabolite signature of T2D prevalence, respectively. Metabotypes associated with T2D were identified using the k-means algorithm. Results. - A …
Polymorphisms cyclooxygenase-2 -765G>C and interleukin-6 -174G>C are associated with serum inflammation markers in a high cardiovascular risk populat…
2009
Inflammation is involved in cardiovascular diseases. Some studies have found that the Mediterranean diet (MD) can reduce serum concentrations of inflammation markers. However, none of these studies have analyzed the influence of genetic variability in such a response. Our objective was to study the effect of the -765G>C polymorphism in the cyclooxygenase-2 (COX-2) gene and the -174G>C polymorphism in the interleukin-6 (IL-6) gene on serum concentrations of IL-6, C-reactive protein, intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule-1 as well as their influence on the response to a nutritional intervention with MD. An intervention study in a high cardiovascular ri…
Novel multimetabolite prediction of walnut consumption by a urinary biomarker model in a free-living population: the PREDIMED study.
2014
The beneficial impact of walnuts on human health has been attributed to their unique chemical composition. In order to characterize the dietary walnut fingerprinting, spot urine samples from two sets of 195 (training) and 186 (validation) individuals were analyzed by an HPLC-q-ToF-MS untargeted metabolomics approach, selecting the most discriminating metabolites by multivariate data analysis (VIP ≥ 1.5). Stepwise logistic regression analysis was used to design a multimetabolite prediction biomarker model. The global performance of the model and each included metabolite in it was evaluated by receiver operating characteristic curves, using the area under the curve (AUC) values. Dietary expos…
Nitric oxide synthase 2 (NOS2) expression in histologically normal margins of oral squamous cell carcinoma
2014
The activity of Nitric Oxide Synthase 2 (NOS2) was found in oral squamous cell carcinomas (OSCC) but not in normal mucosa. Molecular changes associated to early carcinogenesis have been found in mucosa near carcinomas, which is considered a model to study field cancerization. The aim of the present study is to analyze NOS2 expression at the histologically normal margins of OSCC. Study Design: Eleven biopsy specimens of OSCC containing histologically normal margins (HNM) were analyzed. Ten biopsies of normal oral mucosa were used as controls. The activity of NOS2 was determined by immunohistochemistry. Salivary nitrate and nitrite as well as tobacco and alcohol consumption were also analyzed…
