Genetic diversity and structure of the portuguese pear (Pyrus communis L.) germplasm

A rich heritage of traditional pear varieties is kept in national Portuguese collections. Out of these varieties, “Rocha” dominates national pear production. Although a noticeable phenotypic variation among clones of this variety has been reported, little is known about its genetic variability, as to date molecular studies have been performed on a single “Rocha” clone. Eleven Simple Sequence Repeats (SSR) markers were used to assess the genetic diversity of 130 local cultivars, 80 of them being “Rocha” clones. The results allowed the di erentiation of 75 genotypes of which 29 are “Rocha”. Three synonyms groups and four homonymous groups of other local varieties were confirmed. A Bayesian model-based clustering approach identified two distinct clusters. Using flow cytometry, six cultivars were found to be triploids. These results show high genetic variability among “Rocha” clones. In conclusion, there is a need for di erent “Rocha” clones to be preserved to enable the correct selection of the multiplication materialinfo:eu-repo/semantics/publishedVersio

Identidade, marca e consumo: construções simbólicas na tessitura da cultura

O presente artigo tem o objetivo de discutir a marca enquanto construção simbólica, inserida competitivamente no contexto cultural de consumo. A identidade de uma marca depende da dimensão sensível de seus usuários em função de suas experiências. Cabe ao designer gráfico capitalizar essas experiências através de uma comunicação visual, aqui representada pela identidade visual, criando um diferencial estratégico da marca através de conceitos simbólicos. Assim, a identidade pode ser percebida através de linguagens e da manipulação de signos. Também nas histórias construídas pelo design aparecem as significações já existentes na cultura. Cada composição gráfica para expressão da marca é uma composição de fragmentos de dois códigos: um código genético e um código cultural

Effects of dancing on physical activity levels of children and adolescents : a systematic review

Background: Dancing has been suggested to increase the levels of physical activity of the youth. However, it is not clear what are the physiological characteristics of the dance classes for young people, mainly regarding the levels of moderate to vigorous physical activity (MVPA) during classes. It is also unclear if regular engagement in dance practices can contribute with increases in the amounts of daily/weekly MVPA, recommended by health organizations. Objectives: To conduct a systematic review verifying the amount of time spent at MVPA (primary outcome), by children and adolescents in the following situations: i) During dance classes, and ii) Before and after dance in- terventions. Secondary outcomes included: markers of exercise intensity during class, such as oxygen con- sumption (VO2) and heart rate (HR); VO2peak and lipid profile before and after dance interventions. Methods: Six data sources were accessed (MEDLINE, EMBASE, Cochrane Wiley, PEDRO and SCOPUS). Study selection included different designs (acute, cohort, randomized controlled trials and others). Participants were from 6 to 19 years old, regularly engaged in dance practices. Methodological quality was assessed using the Downs and Black checklist. Two independent reviewers extracted characteristics and results of each study. Results: 3216 articles were retrieved, and 37 included. Studies indicated that dance classes do not achieve 50% of total class time at MVPA. However, there are peaks of HR and VO2 during dance classes, which reach moderate and vigorous intensities. MVPA/daily/weekly did not improve before and after dance interventions for most of the studies, also VO2peak did not. The few results on lipid profile showed improvements only in overweight and obese participants. Limitations: Lack of meta-analysis, because there were not enough articles to be analyzed on any given outcome of interest, neither under the same study design. Conclusions: Results of individual studies indicated that dance classes did not active 50% of the total time at MVPA levels. This may be related to the absence of improvements in daily/weekly MVPA before and after dance interventions. VO2 and HR attained peaks of moderateto vigorous intensity during dance classes, suggesting that the structure of the classes may be manipulated to maintain longer periods at MVPA levels. Lack of data on cardiorespiratory fitness and metabolic outcomes limit conclusions on these parameters. Implications of Keys Finds: Considering there are peaks of HR and VO2 during dance classes, we suggest that the structure of a dance class can be manipulate in order to induce cardiorespiratory and metabolic adaptations. Thus, dancing is a potential strategy to contribute with a healthy life style since the earliest ages. Prospero registration: CRD4202014460

The H0 trouble: Confronting Non-thermal Dark Matter and Phantom Cosmology with the CMB, BAO, and Type Ia Supernovae data

We have witnessed different values of the Hubble constant being found in the literature in the past years. Albeit, early measurements often result in an $H_0$ much smaller than those from late-time ones, producing a statistically significant discrepancy, and giving rise to the so-called Hubble tension. The trouble with the Hubble constant is often treated as a cosmological problem. However, the Hubble constant can be a laboratory to probe cosmology and particle physics models. In our work, we will investigate if the possibility of explaining the $H_0$ trouble using non-thermal dark matter production aided by phantom-like cosmology is consistent with the Cosmic Background Radiation (CMB) and Baryon Acoustic Oscillation (BAO) data. We performed a full Monte Carlo simulation using CMB and BAO datasets keeping the cosmological parameters $\Omega_b h^2$, $\Omega_c h^2$, $100\theta$, $\tau_{opt}$, and $w$ as priors and concluded that a non-thermal dark matter production aided by phantom-like cosmology yields at most $H_0=70.5$ km s$^{-1}$Mpc$^{-1}$ which is consistent with some late-time measurements. However, if $H_0> 72$ km s$^{-1}$ Mpc$^{-1}$ as many late-time observations indicate, an alternative solution to the Hubble trouble is needed. Lastly, we limited the fraction of relativistic dark matter at the matter-radiation equality to be at most 1\%.Comment: 13 pages and 5 figure

a scoping review

Background: The interest in Global Health (GH) as an academic discipline has increased in the last dec-ade. This article reports the findings of a scoping review of studies about Global Health education in the Americas. Objective: To analyse educational programs on global health in the Americas. Method: Five electronic databases were used in a scoping review: PubMed, Scopus, Web of Knowledge, CINAHL, and Lilacs. Data collection happened in November 2017–March 2018. The following stages were rigorously observed: identification, selection, charting, and summarizing the studies that were included. To process the data, we used IRaMuTeQ software. Findings: Forty-six studies were identified and organized in categories: 1) diversity of the topics addressed in GH; 2) models of teaching; 3) emotional, cultural, and collaborative aspects in teaching GH; 4) student preparation for GH experiences; and 5) structures required for a GH course. Conclusions: The existing global health curriculum in the Americas is diffuse and limited, with a greater focus on clinical aspects. Thus, a minimum curriculum for students from different areas is needed. Results evidenced that the teaching of global health in the Americas is still incipient, although it is promising. The lack of a common curriculum for the courses in the region makes it difficult to train sensitive and capable professionals to achieve the 2030 Sustainable Development Goals.publishersversionpublishe

Results: in the research, four categories emerged: "The importance of the theme approach in School", "Sexuality demonstrations by students", "The role of teachers in sexual education of students" and "How the school should address the theme?". Conclusion: the approach is based on a vertical transmission of knowledge, based mainly on biological aspects

Biomicroscopia ultrassônica após procedimentos cirúrgicos paliativos na ceratopatia bolhosa: estudo comparativo descritivo

Purpose:To describe quantitative and qualitative features of eyes with advanced bullou keratopathy assessed using ultrasound biomicroscopy, before and after anterior stromal puncture (ASP) or amniotic membrane transplantation (AMT) procedures to relieve chronic pain.Methods:The present descriptive comparative study included 40 eyes of 40 patients with chronic intermittent pain due to bullous keratopathy who were randomly assigned to one of the two treatments (AMT or ASP). Ultrasound biomicroscopy (Humphrey, UBM 840, 50 MHz transducer, immersion technique) was used, and a questionnaire about pain intensity was completed preoperatively and postoperatively at days 90 and 180, respectively. Exclusion criteria were age<18 years, presence of concurrent infection, ocular hypertension, and absence of pain.Results:In a 180-day follow-up, the AMT group exhibited mean central corneal thicknes (CCT), 899.4 µm preoperatively and 1122.5 µm postoperatively (p<0.001); mean epithelial thickness (ET), 156.4 µm preoperatively and 247.8 µm postoperatively (p<0.001); and mean stromal thickness (ST), 742.9 µm preoperatively and 826.3 µm postoperatively (p=0.005). The ASP group exhibited mean CCT, 756.7 µm preoperatively and 914.8 µm postoperatively (p<0.001); mean ET, 102.1 µm preoperatively and 245.2 µm postoperatively (p<0.001); and mean ST, 654.6 µm preoperatively and 681.5 µm postoperatively (p<0.999). Correlations between CCT and pain intensity in the AMT group (p=0.209 pre- and postoperatively) and the ASP group (p=0.157 preoperatively and p=0.426 at the 180-day follow-up) were not statistically significant. Epithelial and stromal edema, Descemet’s membrane folds, epithelial bullae, and the presence of interface fluid were frequently observed qualitative features.Conclusion:CCT increased over time in both groups. The magnitude of CCT did not correlate with pain intensity in the sample studied. The presence of interface fluid was a qualitative feature specifically found in some patients who underwent AMT.Objetivo:Descrever as características quantitativas e qualitativas da biomicroscopia ultrassônica (UBM) em olhos com ceratopatia bolhosa avançada, antes e após o procedimentos de punção estromal anterior (ASP) ou transplante de membrana amniótica (AMT) para alívio de dor crônica.Métodos:Estudo comparativo descritivo incluindo 40 olhos de 40 pacientes com dor crônica intermitente devido a ceratopatia bolhosa, randomizados em duas modalidades de tratamento (AMT e ASP). Biomicroscopia ultrassônica (Humphrey, UBM 840, transdutor de 50 MHz, técnica de imersão) foi utilizada, e um questionário de avaliação da intensidade da dor foi aplicado no pré-operatório, e após 90 e 180 dias de pós-operatório. Critérios de exclusão foram: idade abaixo de 18 anos, presença de infecção, hipertensão ocular, e ausência de dor.Resultados:No seguimento de 180 dias, o grupo Transplante de membrana amniótica apresentou: média da espessura corneana central (CCT): 899,4 µm (pré), 1.122,5 µm (pós-operatório) (p<0,001); média da espessura epitelial (ET): 156,4 µm (pré), 247,8 µm (pós-operatório) (p<0,001); média da espessura estromal (ST): 742,9 µm (pré), 826,3 µm (pós-operatório) (p=0,005), e, grupo ASP apresentou: CCT média: 756.7 µm (pré), 914,8µm (pós-operatório) (p<0,001); ET média: 102,1 µm (pré), 245,2 µm (pós-operatório) (p<0,001); ST média: 654,6 µm (pré), 681.5 µm (pós-operatório) (p<0,999). A correlação entre intensidade da dor e espessura corneana central no grupo AMT (p=0,209 pré e pós-operatórios) e no grupo ASP (p=0,157 pré-operatório e p=0,426 aos 180 dias de seguimento) não foi significativa. Edema epitelial e estromal, dobras na membrana de Descemet, bolha epiteliais, e presença de fluido na interface foram características qualitativa frequentemente observadas.Conclusão:A espessura corneana central aumentou ao longo do tempo em ambos os grupos. A magnitude da espessura corneana central não interfere na intensidade da dor na amostra estudada. Presença de fluido na interface foi uma característica qualitativa especificamente encontrada em alguns pacientes submetidos a transplante de membraa amniótica.Foundation for Support to Research of Sao Paulo State, (FAPESP)Federal University of São Paulo Department of Ophthalmology and Visual SciencesUNIFESP, Department of Ophthalmology and Visual Sciences2001/07036-3SciEL
