Genome-wide meta-analyses of multiancestry cohorts identify multiple new susceptibility loci for refractive error and myopia

2013

Refractive error is the most common eye disorder worldwide and is a prominent cause of blindness. Myopia affects over 30% of Western populations and up to 80% of Asians. The CREAM consortium conducted genome-wide meta-analyses, including 37,382 individuals from 27 studies of European ancestry and 8,376 from 5 Asian cohorts. We identified 16 new loci for refractive error in individuals of European ancestry, of which 8 were shared with Asians. Combined analysis identified 8 additional associated loci. The new loci include candidate genes with functions in neurotransmission (GRIA4), ion transport (KCNQ5), retinoic acid metabolism (RDH5), extracellular matrix remodeling (LAMA2 and BMP2) and eye…

Study of the Contribution of Research into Women Entrepreneurship : A Meta-analysis of Discourses in the Literature using ATLAS.ti

2015

Abstract: In this paper, we have analyzed how existing literature contributes to women entrepreneurship research in terms of theoretical, methodological and practical ways of understanding. Based on relevant contents and discourses, a main line within the trend of development can be seen as women entrepreneurship shifting from a marginalized discipline to a more multi-dimensional research concept. Certain representative issues evoke development or are even being left as “atheoretical” at some point; the “alternative” angle is accordingly significant for an in-depth exploration through the relevant materials. The literature resources are chosen with close attention to the keywords “women ent…

Making sense of women entrepreneurship research : a qualitative meta-analytical review

2016

In this study, we explore how extant literature contributes to the development in women entrepreneurship research in terms of both theoretical and practical perspectives. Accordingly, an ostensible tendency can be seen as women entrepreneurship shifting from a marginalized discipline to a mainstream concept concerning more multi-dimensional attributes. Gender has been used as a lens into studies and it is understood as a socially-constructed process – to simply conduct comparative analysis between sexes cannot lead to more fruitful research results – women entrepreneurs needs a medium to undergo their significant contributions and important roles. Literature materials are chosen with the ke…

Zero-shot Semantic Segmentation using Relation Network

2021

Zero-shot learning (ZSL) is widely studied in recent years to solve the problem of lacking annotations. Currently, most studies on ZSL are for image classification and object detection. But, zero-shot semantic segmentation, pixel level classification, is still at its early stage. Therefore, this work proposes to extend a zero-shot image classification model, Relation Network (RN), to semantic segmentation tasks. We modified the structure of RN based on other state-of-the-arts semantic segmentation models (i.e. U-Net and DeepLab) and utilizes word embeddings from Caltech-UCSD Birds 200-2011 attributes and natural language processing models (i.e. word2vec and fastText). Because meta-learning …

A Systematic Review and Metasynthesis of Qualitative Studies on the Competencies of Health and Rehabilitation Science Educators

2020

Background. Health and rehabilitation science educators’ competence greatly influences students’ professional development in a changing world. To ensure the availability of qualified health and rehabilitation science educators in the future, there is a need for continuous reforms in this sector to develop the educators’ competence in this sector. Objective. The aim of this systematic review was to find new evidence on educators’ experiences of their competence in health and rehabilitation science higher education. Methods. The study was a systematic review of previous peer-reviewed qualitative studies. The inclusion criteria were planned according to PICo: health and rehabilitation science …

Of Friends and Foes in Organizations: A Theoretical Perspective Upon Performance at Work

2014

Abstract The present paper highlights, from a theoretical perspective, the main challenges which aim work performance, inside meta- analytical research studies in organizations, focusing, especially, on factors and organizational concepts, directly related to performance and their relations within. Results show that, in most cases, human resources oriented management resides in an increase of performance at work. In this manner, team effectiveness, group size and proactive behavior determine and influence the levels of work performance, from a positive perspective, whilst turnover is widely associated with a negative view.

Should inflammatory pathways be targeted for the prevention and treatment of hypertension?

2019

Hypertension is the most common modifiable risk factor for cardiovascular disease (CVD)1 and is a leading cause of death globally.2 Hypertension and CVD share common antecedent risk factors which include physical inactivity, obesity and excess alcohol intake.3 Though these established risk factors explain a large proportion of hypertension risk, its pathogenesis is still not fully established as it appears that other additional lifestyle and genetic factors may be involved. There is therefore a need to identify and evaluate putative risk factors that may increase our knowledge of hypertension development, may have causal or predictive relevance, and which will help develop preventive and ma…

An unexpected ring carboxylation in the electrocarboxylation of aromatic ketones

2006

The electrocarboxylation of various aromatic ketones, carried out in N-methyl-2-pyrrolidone (NMP) in a diaphragmless cell equipped with a carbon cathode and an aluminium sacrificial anode, yielded, among the products, the target hydroxy acids, the corresponding alcohols and pinacols and, quite surprisingly, detectable amounts of substituted benzoic acids and cycloexene carboxylic acids. These compounds arise from a never reported before electrocarboxylation on the aromatic ring, respectively, for substitution of an aromatic hydrogen and from an addition reaction. For example, the electrocarboxylation of acetophenone gave rise to the substituted benzoic acids in ortho, para and meta position…

Eficacia de la resincronización cardiaca en el tratamiento de la insuficiencia cardiaca sintomática: metaanálisis y análisis económico

2014

La insuficiencia cardiaca es un síndrome clínico crónico, causado por alteraciones funcionales del corazón, generalmente del ventrículo izquierdo (VI). Es un importante problema de salud, con unas elevadas morbilidad y mortalidad. Es una de las enfermedades cardiovasculares que causa más invalidez, más mortalidad y mayor gasto en los países de nuestro entorno, a pesar de los recientes avances en su tratamiento. La terapia de resincronización cardiaca es una opción terapéutica en estos enfermos. Se trata de un marcapasos tricameral, con electrodos localizados en aurícula derecha, ventrículo derecho y en cara lateral de ventrículo izquierdo. Logra corregir la asincronía electromecánica ventri…
