Evidence for protein leverage in a general population sample of children and adolescents
2023
Background/ObjectivesThe strong regulation of protein intake can lead to overconsumption of total energy on diets with a low proportion of energy from protein, a process referred to as protein leverage. The protein leverage hypothesis posits that protein leverage explains variation in energy intake and potentially obesity in ecological settings. Here, we tested for protein leverage and the protein leverage hypothesis in children and adolescents.Subjects/MethodsA population sample of children, mean (SD) age 7.6 (0.4) years (n = 422), followed up at age 9.8 (0.4) years (n = 387) and at age 15.8 (0.4) years (n = 229), participating for the Physical Activity and Nutrition in Children (PANIC) st…
Sujeto X: Aplicación del modelo de asimilación en un sujeto con esquizofrenia
2017
Capítulo 1. Introducción. En este capítulo se realiza una revisión de la historia del cambio en psicoterapia, sobre la base de principal de Orlinsky y Russell (1994). Tras ello pasamos a hacer una revisión de los planteamientos de la investigación de resultados, de sus características y sus objetivos. También se reflejan los tratamientos empíricamente, atendiendo al contexto en el que se plantean y algunos de los aspectos que conlleva su aceptación en cuanto a su visión de los problemas psicológicos y su tratamiento, la atención hacia la técnica frente a otros aspectos que también están presentes, la metodología a utilizar, y la generalización del contexto social donde se origina.

Glial Chloride Homeostasis Under Transient Ischemic Stress
2021
High water permeabilities permit rapid adjustments of glial volume upon changes in external and internal osmolarity, and pathologically altered intracellular chloride concentrations ([Cl–]int) and glial cell swelling are often assumed to represent early events in ischemia, infections, or traumatic brain injury. Experimental data for glial [Cl–]int are lacking for most brain regions, under normal as well as under pathological conditions. We measured [Cl–]int in hippocampal and neocortical astrocytes and in hippocampal radial glia-like (RGL) cells in acute murine brain slices using fluorescence lifetime imaging microscopy with the chloride-sensitive dye MQAE at room temperature. We observed s…
New Frontiers in Cancer Imaging and Therapy Based on Radiolabeled Fibroblast Activation Protein Inhibitors: A Rational Review and Current Progress.
2021
Over the past decade, the tumor microenvironment (TME) has become a new paradigm of cancer diagnosis and therapy due to its unique biological features, mainly the interconnection between cancer and stromal cells. Within the TME, cancer-associated fibroblasts (CAFs) demonstrate as one of the most critical stromal cells that regulate tumor cell growth, progression, immunosuppression, and metastasis. CAFs are identified by various biomarkers that are expressed on their surfaces, such as fibroblast activation protein (FAP), which could be utilized as a useful target for diagnostic imaging and treatment. One of the advantages of targeting FAP-expressing CAFs is the absence of FAP expression in q…
Reproductive Physiology ofAedes(Aedimorphus)vexans(Diptera: Culicidae) in Relation to Flight Potential
2001
Total protein, lipid, and glycogen of Aedes vexans (Meigen) were related linearly to body size at eclosion. Starvation after emergence led to the determination of minimal irreducible amounts of protein, lipid, and glycogen and the availability of the teneral reserves, whereas access to sucrose revealed the potential for reserve synthesis. Glycogenesis and lipogenesis increased reserves approximately 10-fold the teneral value within 1 and 2 wk after emergence, respectively. Carbohydrate feeding was an essential behavior before blood feeding and oogenesis commenced. Female flight was tested on a flight mill. Maximal flights of 10-17 km in a single night occurred at 2 wk posteclosion and paral…
Replication of the association between CHRNA4 rs1044396 and harm avoidance in a large population-based sample.
2015
Harm avoidance is a personality trait characterized by excessive worrying and fear of uncertainty, which has repeatedly been related to anxiety disorders. Converging lines of research in rodents and humans point towards an involvement of the nicotinic cholinergic system in the modulation of anxiety. Most notably, the rs1044396 polymorphism in the CHRNA4 gene, which codes for the α4 subunit of the nicotinic acetylcholine receptor, has been linked to negative emotionality traits including harm avoidance in a recent study. Against this background, we investigated the association between harm avoidance and the rs1044396 polymorphism using data from N=1673 healthy subjects, which were collected …
Genome-wide association study and mouse expression data identify a highly conserved 32 kb intergenic region between WNT3 and WNT9b as possible suscep…

Item does not contain fulltext Bladder exstrophy-epispadias complex (BEEC), the severe end of the urorectal malformation spectrum, has a profound impact on continence as well as sexual and renal functions. It is widely accepted that for the majority of cases the genetic basis appears to be multifactorial. Here, we report the first study which utilizes genome-wide association methods to analyze a cohort comprising patients presenting the most common BEEC form, classic bladder exstrophy (CBE), to identify common variation associated with risk for isolated CBE. We employed discovery and follow-up samples comprising 218 cases/865 controls and 78 trios in total, all of European descent. Our disc…
Testing chemical carcinogenicity by using a transcriptomics HepaRG-based model?
2014
The EU FP6 project carcinoGENOMICS explored the combination of toxicogenomics and in vitro cell culture models for identifying organotypical genotoxic- and non-genotoxic carcinogen- specific gene signatures. Here the performance of its gene classifier, derived from exposure of metabolically competent human HepaRG cells to prototypical non-carcinogens (10 compounds) and hepatocarcinogens (20 compounds), is reported. Analysis of the data at the gene and the pathway level by using independent biostatistical approaches showed a distinct separation of genotoxic from non-genotoxic hepatocarcinogens and non-carcinogens (up to 88 % correct prediction). The most characteristic pathway responding to …
Dificultades de interpretación y de uso de los arrastres en Cabri 3d por estudiantes de E.S.O.
2012
La presente memoria corresponde al Trabajo Fin de Máster demandado dentro del programa del Máster de Investigación de Didácticas Específicas de la Universidad de Valencia. En este proyecto pretendemos contribuir a la mejora de la calidad docente a través de una mejor comprensión del aprendizaje en entornos colaborativos con programas de geometría dinámica. La aparición de programas de geometría dinámica en 3D (PGD 3D) ofrece la oportunidad de utilizarlos en el ámbito escolar. En este sentido, resulta pertinente hacerse las siguientes preguntas genéricas a partir de las cuales surgirán nuestras preguntas de investigación: § ¿Cuáles son la naturaleza y el alcance de la integración de PGD 3D e…
