Propagação vegetativa de manjericão (Ocimum basilicum L.) por estacas de diferentes posições cultivadas sob diferentes substratos
O manjericão (Ocimum basilicum L), é um arbusto herbáceo pertencente à família Lamiaceae. No Brasil é cultivado para fins comerciais, como planta ornamental, medicinal e aromática. Sendo assim, o trabalho objetivou avaliar a melhor forma de propagação vegetativa de manjericão (O. basilicum L) por estacas de diferentes posições cultivadas sob diferentes substratos. Foram testados cinco tipos de substratos (areia, solo, solo+areia, solo+esterco com serragem, solo+esterco) e três partes vegetativas da planta (apical, medial, basal) com aproximadamente 12,5cm de comprimento em tubetes 55cm³. O delineamento utilizado foi de inteiramente casualizados, em esquema de parcelas subsubdivididas e mantidas em sombrite (50% de sombreamento). Após cinquenta e oito dias foram avaliados os comprimentos e o número das raízes e altura de planta. Com base nos resultados apresentados no presente trabalho pode se afirmar que as melhores mudas foram feitas a partir da parte apical da planta e com o substrato composto apenas de solo
Quality and fatty acid profile of chicken sausage added canola oil as partial replacement for animal fat/ Qualidade e perfil de ácido graxo de linguiça de frango com substituição parcial de gordura animal por óleo de canola
The objective of this work was to evaluate the effects of the addition of canola oil to chicken sausage, mainly related to the fatty acid profile and sensory properties. The sausages were produced with the addition of canola oil-based emulsion to replace the saturated fat used to maintain cohesion of the ingredients stored at -8 °C, and the color, pH, and thiobarbituric acid reactive substance (TBARS) levels were determined on days 0, 7, 15, 30, and 45. A reduction in saturated fatty acid content and an increase in monounsaturated and polyunsaturated fatty acids were detected, and stored sausage samples had variable pH that remained within the range of 6.14 - 6.44 regardless of the concentration of substituted oil. Additionally, the TBARS levels were <0.79, indicating low levels of lipid peroxidation in sausage stored for 45 days. The substitution of animal fat with canola oil in sausage resulted in feasible proximal composition and sensory characteristics acceptable by non-trained panels. Moreover, the substitution resulted in nutritional improvements due to an increase in mono- and polyunsaturated fatty acids in the lipid fraction that specifically decreased lipid oxidation
Síndrome de Burnout em profissionais de saúde
A Síndrome de Burnout (SB) é um distúrbio psíquico causado pela exaustão extrema, podendo resultar em adoecimento físico e mental. Essa síndrome é comum em profissionais submetidos à alta carga de estresse diário, como profissionais de saúde. Este trabalho consiste em uma revisão integrativa que objetivou analisar a relação entre a SB, a despersonalização do indivíduo e as suas estratégias de enfrentamento (Coping) durante a pandemia. Para isso, foram selecionados artigos, por meio da plataforma BVS (Biblioteca Virtual em Saúde), com uso dos seguintes descritores: Esgotamento psicológico, Pessoal de saúde, Síndrome, Adaptação psicológica, Infecções por coronavírus e Pandemia. Foi observado que os profissionais da saúde mais suscetíveis foram os que trabalham nas unidades de terapia intensiva. Somado a isso, foi evidenciado que a ausência de atividade física se associou a uma maior exaustão emocional e mais despersonalização. Ademais, outros fatores estressantes contribuem para redução da qualidade de vida do ambiente profissional, como a presença de ambientes inóspitos e limitações do sistema de saúde que apresentam obstáculos ao manejo adequado das questões emocionais dos pacientes e dos profissionais. Nota-se que o esgotamento profissional contribui para a despersonalização do indivíduo, relacionado à presença de sintomas somáticos, como: ansiedade, disfunção social e depressão. Portanto, verifica-se que há falta de consenso dos parâmetros que determinam o diagnóstico da SB e que, além da vida profissional, a vida pessoal também é prejudicada, principalmente durante períodos pandêmicos como o da COVID-19, que sobrecarregaram o sistema de saúde. Dessa forma, sugere-se que novos estudos busquem identificar de maneira mais específica quais os profissionais de saúde mais suscetíveis a essa síndrome e que esses funcionários recebam uma atenção psicológica maior. Por fim, ratifica-se a ampliação da disponibilização de atendimento psiquiátrico, além de uma atenção maior à saúde emocional direcionada aos funcionários da UTI, especialmente em situações de pandemia
A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area
Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states
SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal
Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by
the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration
with more than 50 laboratories distributed nationwide.
Methods By applying recent phylodynamic models that allow integration of individual-based
travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal.
Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from
European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland),
which were consistent with the countries with the highest connectivity with Portugal.
Although most introductions were estimated to have occurred during early March 2020, it is
likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the
first cases were confirmed.
Conclusions Here we conclude that the earlier implementation of measures could have
minimized the number of introductions and subsequent virus expansion in Portugal. This
study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and

ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America
Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.

Esthetic perception of facial profile after treatment with the Thurow appliance
The objective of this article was to investigate the perception of esthetic changes in the facial profile of bilateral Class II patients treated with the Modified Thurow Appliance for extraoral treatment. Silhouettes were traced of profiles of patients who initially presented a bilateral Class II molar relationship and who, post-treatment, presented molars in a Class I relationship. Three groups were formed: the first composed of patients with maxillary protrusion (SNA >84°), the second with maxillary retrusion (SNA <80°), and the third with a well-positioned maxilla (SNA 80-84°). A panel of 200 lay evaluators judged the profile esthetics by a randomized drawing of the silhouettes. The multiple analysis results showed that the profile esthetic scores for the three positions of the maxilla were greatly influenced by significant interactions with the characteristics (like sex and age) of the evaluators: retrusive maxilla (Score *Age Group, p< 0.001), normal maxilla (Score *Sex, p= 0.024; Score *Age Group,p= 0.050) and protrusive maxilla (Score *Age Group,p< 0.001). It was observed that the profile of Class II patients with protrusion, normal relationship and retrusion of the maxilla, improved in their esthetic post-treatment result; however, the evaluators showed greater satisfaction with the groups of protrusion and normal position of the maxilla. The Modified Thurow Appliance provided significant improvements in the esthetics of the profile of patients who presented protrusion and normal position of the maxilla. However, its use was not the best treatment option for patients with maxillary retrusion
Prevalência da síndrome metabólica e seus fatores associados em Governador Valadares (MG, Brasil) – Um estudo piloto / Prevalence of metabolic syndrome and its associated factors in Governador Valadares (MG, Brazil) – A pilot study
Introdução: A Síndrome Metabólica (SM) é caracterizada como um agrupamento de fatores que aumentam o risco doenças cardiovasculares e do diabetes mellitus tipo 2. Estudos sobre as estimativas epidemiológicas desta doença podem ser uma estratégia de prevenção. Apesar da importância da SM, poucos trabalhos descrevem a prevalência da SM e seus determinantes no Brasil. Objetivo: O presente estudo tem como objetivo avaliar a prevalência da SM e de seus componentes em Governador Valadares, MG. Métodos: Este estudo foi realizado entre 2018 e 2019. É um estudo transversal de base populacional, envolvendo 201 adultos, com idade entre 18 a 65 anos, selecionados aleatoriamente. Resultados: A SM foi definida pelos critérios da NCEP-ATP-III. A prevalência geral de SM foi de 31,96%, não apresentando diferença significativa entre homens e mulheres. A circunferência da cintura elevada (49,25%) e a hipertensão (42%) foram os componentes mais prevalentes. A ocorrência de SM foi maior em participantes obesos (54,55%), em indivíduos com baixa escolaridade (53,42%) e com idade mais elevada (37,97%). Conclusão: Os resultados deste estudo preliminar em Governador Valadares podem ajudar no desenvolvimento de estratégias de promoção da saúde, enfatizando a educação sobre SM, a fim de prevenir a morbidade e mortalidade associada a esta síndrome.
Neuroendocrine Inflammatory Responses in Overweight/Obese Infants.
Childhood obesity is related to a cascade of neuroendocrine inflammatory changes. However, there remains a gap in the current literature regarding the possible occurrence of these changes in overweight/obese infants. The objective of this study was to evaluate adipokines, cortisol, brain-derived neurotrophic factor (BDNF) and redox status in overweight/obese infants versus normal-weight peers. A cross-sectional study was conducted with 50 infants (25 in the overweight/obese group and 25 in the normal-weight group) between 6 and 24 months. Plasma levels of leptin, adiponectin, resistin, soluble tumor necrosis factor (TNF) receptors, chemokines, BDNF, serum cortisol and redox status were measured. Unpaired Student's t-test was used to analyze the results and a probability of p<0.05 was acceptable for rejection of the null hypothesis. The Pearson correlation was used to verify the association between the biomarkers analyzed in each group. Plasma levels of leptin (p = 0.0001), adiponectin (p = 0.0007) and BDNF (p = 0.003), and serum cortisol (p = 0.048) were significantly higher in overweight/obese infants than normal-weight infants. In contrast, the concentration of thiobarbituric acid reactive substances (TBARS) (p = 0.004), and catalase (p = 0.045) and superoxide dismutase activity (p = 0.02) were lower in overweight/obese infants than normal-weight peers. All the results together indicate neuroendocrine inflammatory response changes in overweight/obese infants between 6 and 24 months. Although there is already an environment that predisposes for a subsequent pro-inflammatory response, neuroendocrine secretion changes that permit the control of the inflammatory process in this age interval can be observed
