Resumo Este trabalho busca lançar luz sobre leituras sociais a respeito da violência sexual contra mulheres, tendo como base para análise o estupro coletivo de uma adolescente na periferia do Rio de Janeiro, em 2016. Elencando como solo empírico matérias e comentários de leitores do portal G1, o objetivo é perceber se predominou uma tônica consensual ou dissensual na apropriação do fato. O aporte teórico aciona as noções de acontecimento e enquadramento, representação, problema público, valores e normas. O método articulou uma quantificação dos enunciados e dimensões qualitativas extraídas do eixo conceitual. A análise apresenta a existência de disputas de sentido sobre o acontecimento, principalmente entre leitores das notícias. Mostra ainda a tendência a representações da vítima e dos suspeitos baseadas no comportamento feminino — tomado como marco-zero dos sentidos atribuídos ao ocorrido. Já as soluções propostas enfatizam mais a punição e respostas paliativas para um problema estrutural.

Abstract This paper seeks to shed light on social readings about sexual violence against women, based on the collective rape against a teenager in Rio de Janeiro in 2016. Taking news and comments from readers of the G1 Portal as empirical, the aim is to understand whether a consensual or discordant tonic prevailed in the appropriation of the fact. The theoretical contribution triggers the notions of event and framing, representation, public problem, values, and norms. The method articulates a quantification of the statements and qualitative dimensions extracted from the conceptual axis. The analysis presents the existence of disputes about the meaning of the event, especially among news readers. It also shows the tendency towards representations of the victim and suspects based on female behavior – taken as a base line of the meanings attributed to what happened. The proposed solutions emphasize punishment and palliative responses to a structural problem.

Resumo O objetivo deste estudo foi verificar a prevalência de sobrepeso e obesidade, além da associação entre o índice de massa corporal (IMC) com os fatores de risco cardiovascular em professores da rede pública. Foi realizado um estudo transversal em 200 professores da educação básica de Viçosa-MG. Avaliaram-se o IMC, a circunferência de cintura (CC), a relação cintura-quadril (RCQ), o percentual de gordura corporal (%GC), a pressão arterial sistólica e diastólica, a glicemia de jejum, o colesterol total, a lipoproteína de alta e baixa densidade (LDL-C), os triglicerídeos e o número de passos diários. Avaliaram-se as associações entre o IMC (variável independente) e demais variáveis (variável dependente) por meio da regressão linear. Foram encontrados 58% de excesso de peso entre os professores, sendo que 20% apresentaram obesidade. Entre o sexo feminino, todos os fatores de risco foram estatisticamente diferentes entre o grupo com sobrepeso e/ou obesidade comparados ao grupo classificado com IMC normal, exceto para o colesterol total e LDL-C. O valor de passos diários apresentou tendência de redução com o aumento do IMC. A análise de regressão linear mostrou associação positiva entre o IMC e as demais medidas antropométricas, pressóricas e bioquímicas, porém, após correção pela idade, apenas observou-se associação com as variáveis antropométricas (CC, RCQ e %GC). Foi encontrada uma elevada prevalência de sobrepeso/obesidade nos professores da educação básica. O indicador de obesidade geral (IMC) não apresentou associação com os fatores de risco cardiovascular, quando ajustado em função da idade.

Abstract The objective of this study was to determine the prevalence of overweight and obesity and the association of body mass index (BMI) with cardiovascular risk factors in public school teachers. A cross-sectional study was conducted on 200 basic education teachers from Viçosa, MG. We assessed BMI, waist circumference (WC), waist-hip ratio (WHR), body fat percentage (%BF), systolic and diastolic blood pressure, fasting glucose, total cholesterol, high-density and low-density lipoprotein (LDL-C), triglycerides, and number of daily steps. Linear regression was used to evaluate the associations between BMI (independent variable) and the other variables (dependent variable). Overweight was observed in 58% of the teachers and obesity in 20%. Among women, all risk factors differed significantly between the group with overweight and/or obesity and the group classified as normal BMI, except for total cholesterol and LDL-C. Linear regression analysis showed a positive association between BMI and the other anthropometric measurements, blood pressure, and biochemical parameters; however, after adjustment for age, an association was only observed with the anthropometric variables (WC, WHR, and %BF). The prevalence of overweight/obesity was high among the basic education teachers studied. The overall obesity indicator (BMI) was not associated with cardiovascular risk factors when adjusted for age.

BACKGROUND: It is important to include large sample sizes and different factors that influence the six-minute walking distance (6MWD) in order to propose reference equations for the six-minute walking test (6MWT). OBJECTIVE: To evaluate the influence of anthropometric, demographic, and physiologic variables on the 6MWD of healthy subjects from different regions of Brazil to establish a reference equation for the Brazilian population. METHOD: In a multicenter study, 617 healthy subjects performed two 6MWTs and had their weight, height, and body mass index (BMI) measured, as well as their physiologic responses to the test. Delta heart rate (∆HR), perceived effort, and peripheral oxygen saturation were calculated by the difference between the respective values at the end of the test minus the baseline value. RESULTS: Walking distance averaged 586±106m, 54m greater in male compared to female subjects (p<0.001). No differences were observed among the 6MWD from different regions. The quadratic regression analysis considering only anthropometric and demographic data explained 46% of the variability in the 6MWT (p<0.001) and derived the equation: 6MWDpred=890.46-(6.11×age)+(0.0345×age2)+(48.87×gender)-(4.87×BMI). A second model of stepwise multiple regression including ∆HR explained 62% of the variability (p<0.0001) and derived the equation: 6MWDpred=356.658-(2.303×age)+(36.648×gender)+(1.704×height)+(1.365×∆HR). CONCLUSION: The equations proposed in this study, especially the second one, seem adequate to accurately predict the 6MWD for Brazilians.

Citrus sinensis is a perennial woody species, for which genetic approaches to the study of reproductive development are not readily amenable. Here, the usefulness of the CitEST Expressed Sequence Tag (EST) database is demonstrated as a reliable new resource for identifying novel genes exclusively related to Citrus reproductive biology. We performed the analysis of an EST dataset of the CitEST Project containing 4,330 flower-derived cDNA sequences. Relying on bioinformatics tools, sequences exclusively present in this flower-derived sequence collection were selected and used for the identification of Citrus putative flower-specific genes. Our analysis revealed several Citrus sequences showing significant similarity to conserved genes known to have flower-specific expression and possessing functions related to flower metabolism and/or reproductive development in diverse plant species. Comparison of the Citrus flower-specific sequences with all available plant peptide sequences unraveled 247 unique transcripts not identified elsewhere within the plant kingdom. Additionally, 49 transcripts, for which no biological function could be attributed by means of sequence comparisons, were found to be conserved among plant species. These results allow further gene expression analysis and possibly novel approaches to the understanding of reproductive development in Citrus.

Floral transition is one the most drastic changes occurring during the life cycle of a plant. The shoot apical meristem switches from the production of leaves with associated secondary shoot meristems to the production of flower meristems. This transition is abrupt and generally irreversible, suggesting it is regulated by a robust gene regulatory network capable of driving sharp transitions. The moment at which this transition occurs is precisely determined by environmental and endogenous signals. A large number of genes acting within these pathways have been cloned in model herbaceous plants such as Arabidopsis thaliana. In this paper, we report the results of our search in the Citrus expressed sequence tag (CitEST) database for expressed sequence tags (ESTs) showing sequence homology with known elements of flowering-time pathways. We have searched all sequence clusters in the CitEST database and identified more than one hundred Citrus spp sequences that codify putative conserved elements of the autonomous, vernalization, photoperiod response and gibberelic acid-controlled flowering-time pathways. Additionally, we have characterized in silico putative members of the Citrus spp homologs to the Arabidopsis CONSTANS family of transcription factors.
