Evolución de la desinformación sobre COVID-19 en Argentina a través de los desmentidos del verificador Chequeado

2022

Este trabajo estudia la evolución de la desinformación sobre COVID-19 en Argentina desde la declaración de la situación de pandemia por la OMS en marzo de 2020 hasta junio de 2021. La investigación aplica un análisis de contenido de cuatro variables —intención, temática, protagonismo y apelación emocional— a los 154 desmentidos publicados al respecto en dicho periodo por el medio Chequeado, único del país acreditado por la International Fact-Checking Network. Los resultados evidencian el predominio de la intención desestabilizadora, la temática negacionista, el protagonismo de las instituciones y del personal sanitario, y la apelación emocional negativa. Además, la puesta en relación de dic…

Expression of the human XPB/ERCC-3 excision repair gene-homolog in the sponge Geodia cydonium after exposure to ultraviolet radiation.

1998

Abstract The marine demosponge Geodia cydonium encodes a gene, termed GCXPB , which displays 62% identity to the human XPB/ERCC-3 gene that specifically corrects the repair defect in xeroderma pigmentosum and in Cockayne's syndrome. The cDNA was isolated and characterized the deduced aa sequence, XPB_GEOCY, with the calculated size of 91,541 Da comprises the characteristic domains found in the related helicases. Phylogenetic tree analysis revealed that the sponge sequence is grouped to the metazoan related XPB/ERCC-3 polypeptides. Northern Blot analyses have been performed with sponge samples collected at different depths, thus exposed to different intensities of UV sunlight in the field. T…

Cytotoxicity of compounds from Xylopia aethiopica towards multi-factorial drug-resistant cancer cells.

2015

Abstract Introduction Multidrug resistance (MDR) in cancer represent a major hurdle in chemotherapy. Previously, the methanol extract of the medicinal spice Xylopia aethiopica displayed considerable cytotoxicity against multidrug resistant (MDR) cancer cell lines. Methods The present study was designed to assess the cytotoxicity of compounds, 16 α -hydroxy- ent -kauran-19-oic acid ( 2 ), 3,4′,5-trihydroxy-6″,6″-dimethylpyrano[2,3-g]flavone ( 3 ), isotetrandrine ( 5 ) and trans -tiliroside ( 6 ) derived from the methanol crude extract of Xylopia aethiopica against 9 drug-sensitive and -resistant cancer cell lines. The resazurin reduction assay was used to evaluate the cytotoxicity of these c…

Infant feeding practices and early growth among children of the nationwide Elfe cohort

2020

International audience; Rapid early growth is considered as a risk factor for obesity later in life. Breastfeeding is associated with slower growth in the first months of life, but the complementary diet of non- exclusively breastfed infants remains poorly considered. Our objective was to analyze the links between infant diet during the first year and growth up to 18 months. Analyses included 8315 infants from the Elfe birth cohort. Infants were grouped into clusters using hierarchical clustering according to infant diet characteristics (breastfeeding duration, introduction of infant formula, main food groups and unmixed foods). Association between clusters and weight, height and BMI betwee…

Initiating complementary feeding: a decision influenced by the child's growth?

2020

International audience; Background and aims: Infant feeding practices are subject to multiple influences. The age of onset of complementary feeding (CF) varies according to many factors such as maternal characteristics (smoking, age, education level, body size, country of birth) or infant characteristics (sex) (Bournez et al., 2017). The aim was to study if, in addition to these factors, age could depend on the child's growth. We have hypothesized that larger children (or heavier / more corpulent ones) would be introduced to CF earlier than "average"-sized children would. Methods: Data from the ELFE cohort (French Longitudinal Study since Childhood) made it possible to describe the age of C…

HabEat: Understanding critical periods and critical factors of the formation and of the modification of food habits

2011

Introduction: Diets of young children in many European countries are not ideal (too many lipids; not enough fruit and vegetables). Early nutrition may have an impact on health in later life (diabetes, obesity, heart problems) and the first two years of life are of crucial importance in the acquisition of food habits. The HabEat project aims at understanding better of how food habits are formed and can be changed, in infants and children (< 5 years). Methods: With 11 beneficiaries from 6 European countries, HabEat (2010-2013) is based on a multidisciplinary approach (epidemiology, nutrition, behavioural science, psychology and sensory science). On one hand, in order to identify critical peri…

Périodes et facteurs sensibles pour la formation précoce des préférences alimentaires

2015

Eating behavior is a complex, essentially learned activity critical for development and survival. It can be broken down into several components: when, how, what and how much to eat.1,2 We will mainly describe in this chapter the important periods and factors associated with the development of “what” to eat, or in other words, food preferences and choice. Other aspects relevant to the early development of eating behavior have been previously reviewed.2,3 Although it has previously been shown that food and flavor preference may be influenced by flavor exposure during the prenatal period4-6, we will focus in this chapter on the acquisition of food preferences consecutive to direct exposure of …

Détermination et transmission du goût. Importance des expériences précoces

2013

Compte tenu que les préférences et habitudes alimentaires sont acquises très précocement il est important de mieux comprendre l’impact des expériences précoces sur l’acceptation des fruits et légumes lors de la diversification alimentaire et pendant les premières années de vie. Au cours de cette présentation, des résultats d’études expérimentales ou observationnelles portant sur l’impact de l’allaitement, des pratiques de diversification (variété de l’offre, exposition répétée) et des pratiques éducatives sur l’acceptation des fruits et légumes seront présentées. La transmission des préférences alimentaires peut commencer au cours de la vie intra-utérine. Il a été montré que des nouveau-nés…

Use of added sugar, salt and fat in the first year in France and associated factors in the ELFE cohort study

2018

National audience; Background and Aims: To describe added sugar, salt and fat uses and their determinants during complementary feeding (CF) period in infants aged 3 to 10 months. Methods: Data are drawn from the ELFE study (Etude longitudinale Française depuis l'Enfance) which included >18000 infants in 2011. A frequency food questionnaire of consumption of added sugar, salt and fat was monthly completed by the mother from the 3rd to the 10th month (N=10,649). The associations between the use of each added-ingredient and (1) socio-economic characteristics and (2) infant care and feeding practices were studied with two models (the second including the factors of the first) with multivariate …
