A Microarray study of Carpet-Shell Clam (Ruditapes decussatus) shows common and organ-specific growth-related gene expression Differences in gills and digestive gland

Growth rate is one of the most important traits from the point of view of individual fitness and commercial production in mollusks, but its molecular and physiological basis is poorly known. We have studied differential gene expression related to differences in growth rate in adult individuals of the commercial marine clam Ruditapes decussatus. Gene expression in the gills and the digestive gland was analyzed in 5 fast-growing and five slow-growing animals by means of an oligonucleotide microarray containing 14,003 probes. A total of 356 differentially expressed genes (DEG) were found. We tested the hypothesis that differential expression might be concentrated at the growth control gene core (GCGC), i. e., the set of genes that underlie the molecular mechanisms of genetic control of tissue and organ growth and body size, as demonstrated in model organisms. The GCGC includes the genes coding for enzymes of the insulin/ insulin-like growth factor signaling pathway (IIS), enzymes of four additional signaling pathways (Raf/ Ras/ Mapk, Jnk, TOR, and Hippo), and transcription factors acting at the end of those pathways. Only two out of 97 GCGC genes present in themicroarray showed differential expression, indicating a very little contribution of GCGC genes to growth-related differential gene expression. Forty eight DEGs were shared by both organs, with gene ontology (GO) annotations corresponding to transcription regulation, RNA splicing, sugar metabolism, protein catabolism, immunity, defense against pathogens, and fatty acid biosynthesis. GO termenrichment tests indicated that genes related to growth regulation, development and morphogenesis, extracellular matrix proteins, and proteolysis were overrepresented in the gills. In the digestive gland overrepresented GO terms referred to gene expression control through chromatin rearrangement, RAS-related small GTPases, glucolysis, and energy metabolism. These analyses suggest a relevant role of, among others, some genes related to the IIS, such as the ParaHox gene Xlox, CCAR and the CCN family of secreted proteins, in the regulation of growth in bivalves.Direccion General de Investigacion Cientifica y Tecnica of the Spanish Government [AGL2010-16743, AGL2013-49144-C3-3-R]; COMPETE Program; Portuguese National Funds [PEst-255 C/MAR/LA0015/2011]; Portuguese FCT [UID/Multi/04326/2013]; Generalitat Valenciana; Ministry of Education, Culture, and Sports of the Spanish Government; Association of European Marine Biology Laboratoriesinfo:eu-repo/semantics/publishedVersio

Feature Selection for Big Visual Data: Overview and Challenges

International Conference Image Analysis and Recognition (ICIAR 2018, Póvoa de Varzim, Portugal

A scalable saliency-based Feature selection method with instance level information

Classic feature selection techniques remove those features that are either irrelevant or redundant, achieving a subset of relevant features that help to provide a better knowledge extraction. This allows the creation of compact models that are easier to interpret. Most of these techniques work over the whole dataset, but they are unable to provide the user with successful information when only instance information is needed. In short, given any example, classic feature selection algorithms do not give any information about which the most relevant information is, regarding this sample. This work aims to overcome this handicap by developing a novel feature selection method, called Saliency-based Feature Selection (SFS), based in deep-learning saliency techniques. Our experimental results will prove that this algorithm can be successfully used not only in Neural Networks, but also under any given architecture trained by using Gradient Descent techniques

Circulant Digraph Isomorphisms

We determine necessary and sufficient conditions for a Cayley digraph of the cyclic group of order n to have the property that any other Cayley digraph of a cyclic group of order n is isomorphic to the first if and only if an isomorphism between the two digraphs is a group automorphism of the cyclic group of order n

Las identidades de la religión castreña: propuesta de estudio

El presente texto deriva del trabajo de fin de máster Religión e identidad en el Noroeste peninsular prerromano: un ensayo de aproximación dirigido por Eduardo Sánchez Moreno, en el Máster Interuniversitario de Historia y Ciencias de la Antigüedad, presentado durante el curso académico 2012-2013El presente artículo tiene como objetivo ofrecer un modelo de compresión de las manifestaciones religiosas del Noroeste peninsular prerromano del Hierro Final, de acuerdo con sus posibles funciones para las diferentes sociedades castreñas. Se pretende ilustrar cómo la relación entre ciertos esquemas ideológicos y manifestaciones sociales puede ser entendida a través de los procesos de construcción de diversos tipos de identidades y de reformulación de la memoria cultural castreña. Y, de este modo, lograr una comprensión más exhaustiva y completa de la religión de esta cultura mediante la cual, quizás, integrar los datos que conservamos dispersos sobre la mismaThis article aims to provide a model in order to understand religious manifestations of the pre-Roman peninsular North-West area in the late Iron Age, according to their possible functions for different hillfort societies. It is intended to illustrate how the relationship between certain ideological schemes and social events can be understood through the processes of construction of several types of identities and the reshaping of the hillfort cultural memory. Thus, the focus of this article is to achieve a more thorough and comprehensive understanding of the hillfort religion, which might help to integrate the scattered data preserve

"Manvert Silikon's" effect on the protection of the tomato against aluminium

Traballo fin de grao (UDC.CIE). Bioloxía. Curso 2016/2017[Resumen] El aluminio (Al) es un metal muy tóxico para la mayoría de las plantas a muy bajas concentraciones. Tiene la capacidad de inhibir o reducir considerablemente el crecimiento vegetativo de las plantas y con ello disminuir la producción de los cultivos hortícolas. En este trabajo se evaluó el efecto de protección que el producto comercial Manvert Silikon, de la empresa Biovert S.L., tiene sobre el desarrollo de la planta frente al aluminio que pueda haber en el medio. En concreto se trabajó con tomate (Solanum lycopersicum L.), centrándonos en su crecimiento vegetativo y distintos aspectos del metabolismo como la composición de la pared radicular, la expresión del gen LHA y el contenido en proteínas. Se observaron cambios en la proporción de los componentes de pared celular a nivel de la raíz, detectándose un mayor contenido de compuestos fenólicos en las plantas afectadas por aluminio mientras que las plantas tratadas por Manvert Silikon presentaban mayor contenido en polisacáridos y mayor expresión del gen LHA en solución, aunque de manera no significativa. No se observaron diferencias para el contenido en proteínas entre los tratamientos. Con todo esto, se puede afirmar que el aluminio afecta a la fisiología de la planta activando mecanismos de protección y resistencia en ella.[Resumo] O aluminio (Al) é un metal moi tóxico para a maioría das plantas e a moi baixas concentracións.

It has the capacity to inhibit or reduce considerably the vegetative growth of plants, diminishing the production of the horticultural crops. In this work, the protective effect of the commercial product Manvert Silikon, from the company Biovert S.L., was assessed on the development of plants against the aluminum that can be in the medium. In particular, we worked with tomato (Solanum lycopersicum L.), focusing on its vegetative growth and different aspects of metabolism such as the root cell wall composition, the expression of the LHA gene and the protein content. Changes in the proportion of cell wall components at the root level were observed, with a higher content of phenolic compounds in the plants affected by aluminum, while the plants treated with Manvert Silikon showed higher polysaccharide content and higher expression of the LHA gene in solution, although not significantly. No differences were observed for the protein content between treatments. Therefore, we can suggest that aluminum affects the physiology of the plant by activating different mechanisms of protection and resistance
