Indomethacin counteracts the effects of chronic social defeat stress on emotional but not recognition memory in mice
2017
We have previously observed the impairing effects of chronic social defeat stress (CSDS) on emotional memory in mice. Given the relation between stress and inflammatory processes, we sought to study the effectiveness of the anti-inflammatory indomethacin in reversing the detrimental effects of CSDS on emotional memory in mice. The effects of CSDS and indomethacin on recognition memory were also evaluated. Male CD1 mice were randomly divided into four groups: non-stressed + saline (NS+SAL); non-stressed + indomethacin (NS+IND); stressed + saline (S+SAL); and stressed + indomethacin (S+IND). Stressed animals were exposed to a daily 10 min agonistic confrontation (CSDS) for 20 days. All subjec…
Minors and Transexuality
2020
[ES] En el ámbito de la transexualidad los poderes públicos han ejercido desde un principio una política claramente restrictiva que ha requerido de años para poder abrirse a las nuevas necesidades y a la sociedad actual. Así, la normativa en la materia era totalmente excluyente de los menores de edad, considerándolos carentes de aptitud alguna para poder decidir sobre su identidad sexual y todo lo que ello conllevaba, quizá porque como afirman algunos autores “la finalidad básica de esa prohibición es la de garantizar que la decisión de la rectificación registral sea una decisión firme y coherente, evitando así cambios arbitrarios o no fundados en el sexo” (Vázquez-Pastor, 2010).Esta idea p…
Prospects and challenges for computer simulations of monolayer-protected metal clusters
2021
Precise knowledge of chemical composition and atomic structure of functional nanosized systems, such as metal clusters stabilized by an organic molecular layer, allows for detailed computational work to investigate structure-property relations. Here, we discuss selected recent examples of computational work that has advanced understanding of how these clusters work in catalysis, how they interact with biological systems, and how they can make self-assembled, macroscopic materials. A growing challenge is to develop effective new simulation methods that take into account the cluster-environment interactions. These new hybrid methods are likely to contain components from electronic structure t…
Culinary choices: A sociopsychological perspective based on the concept of distance to the object
2015
Culinary choices are a dynamic process that involves many considerations, including individual, contextual, cultural, and social factors. This study provides a better understanding of how culinary socialization along with food neophobia, culinary decisions and culinary habits, underlie culinary choices, measured by the concept of Distance to the Object (DO). This concept is useful in exploring the role of some psychosocial factors: knowledge (real and perceived), involvement (importance, personal identification, perceived ability), and level of practices (behaviors) associated with the social object under study, here, cooking. In this study, the DO concept measures the relationships of an i…
Robust Analysis of Time Series in Virome Metagenomics
2018
Metagenomics is a powerful tool for assessing the functional and taxonomic contents in biological samples as it makes feasible to study, simultaneously, the whole living community related to a host organism or medium: all the microbes, including virus, bacteria, archaea, fungi, and protists. New DNA and RNA sequencing technologies are dramatically decreasing the cost per sequenced base, so metagenomic sequencing is becoming more and more widespread in biomedical and environmental research. This is opening the possibility of complete longitudinal metagenomic studies, which could unravel the dynamics of microbial communities including intra-microbiome and host-microbiome interactions through …
High-Throughput Mapping of 2′-O-Me Residues in RNA Using Next-Generation Sequencing (Illumina RiboMethSeq Protocol)
2017
Detection of RNA modifications in native RNAs is a tedious and laborious task, since the global level of these residues is low and most of the suitable physico-chemical methods require purification of the RNA of interest almost to homogeneity. To overcome these limitations, methods based on RT-driven primer extension have been developed and successfully used, sometimes in combination with a specific chemical treatment. Nowadays, some of these approaches have been coupled to high-throughput sequencing technologies, allowing the access to transcriptome-wide data. RNA 2'-O-methylation is one of the ubiquitous nucleotide modifications found in many RNA types from bacteria, archaea, and eukarya.…
E-beam crosslinked nanogels conjugated with monoclonal antibodies in targeting strategies
2017
Abstract Poly(N-vinyl pyrrolidone)-based-nanogels (NGs), produced by e-beam irradiation, are conjugated with monoclonal antibodies (mAb) for active targeting purposes. The uptake of immuno-functionalized nanogels is tested in an endothelial cell line, ECV304, using confocal and epifluorescence microscopy. Intracellular localization studies reveal a faster uptake of the immuno-nanogel conjugate with respect to the ‘bare’ nanogel. The specific internalization pathway of these immuno-nanogels is clarified by selective endocytosis inhibition experiments, flow cytometry and confocal microscopy. Active targeting ability is also verified by conjugating a monoclonal antibody which recognizes the αv…
Visualizing Human Protein‐Protein Interactions and Subcellular Localizations on Cell Images Through CellMap
2020
Visualizing protein data remains a challenging and stimulating task. Useful and intuitive visualization tools may help advance biomolecular and medical research; unintuitive tools may bar important breakthroughs. This protocol describes two use cases for the CellMap (http://cellmap.protein.properties) web tool. The tool allows researchers to visualize human protein-protein interaction data constrained by protein subcellular localizations. In the simplest form, proteins are visualized on cell images that also show protein-protein interactions (PPIs) through lines (edges) connecting the proteins across the compartments. At a glance, this simultaneously highlights spatial constraints that prot…
Gross motor proficiency and intellectual functioning
2018
This cross-sectional study examines differences in gross motor proficiency as a function of different intellectual functioning profiles. Two motor areas have been investigated as being equally essential to gross motor functions in every-day life: locomotion and object control. It aims to compare gross motor skills endorsed by children with Down syndrome (DS), children with borderline intellectual functioning (BIF), and typically developing children (TDC). Group 1 was composed of 18 children with DS (chronological age=8.22), group 2 was composed of 18 children with BIF (chronological age=9.32), and group 3 was composed of 18 children with typical development (TD) (chronological age=9.28). Gr…
Do typically and atypically developing children learn and generalize novel names similarly: The role of conceptual distance during learning and at te…
2020
International audience; There is a large body of evidence showing that comparison of multiple stimuli leads to better conceptualization and generalization of novel names than no-comparison settings in typically developing (TD) children. By contrast, the evidence regarding this issue remains scarce in children with intellectual disabilities (ID). Children with intellectual disabilities (ID) and TD children matched on mental age with the Raven's coloured progressive matrices were tested in several novel name learning comparison conditions, with familiar objects. We manipulated the conceptual distance between the learning stimuli in the learning phase and between the learning and generalizatio…
