double-blind crossover study

Background: to evaluate the effects of one week of supplementation with curcumin combined with piperine on physical performance, immune system cell counts, muscle damage, and plasma levels of inflammatory markers after a treadmill running training session. Methods: This study is a double-blind, crossover-balanced clinical trial with a three-week intervention. Sixteen male runners with a mean age of 36 ± 9 years and VO2 max of 60.6 ± 9.03 mL.kg −1 min −1 were recruited and randomly divided into 2 groups: the first group (CPG) was supplemented daily for 7 days with 500 mg of curcumin + 20 mg piperine, and the second group (PG) was supplemented with 540 mg of cellulose. After the 7th day of supplementation, the volunteers participated in the experimental running protocol, where blood samples were collected before, after, and one hour after exercise for analysis of the number of leukocytes, creatine kinase, and cytokine concentration (IL-2, TNF-α, IFN, IL-6, and IL-10) using flow cytometry. This process was repeated, reversing the supplementation offered to the groups. Results: curcumin and piperine supplementation could not change the physical performance, immune cell counts, and muscle damage; however, the aerobic fatiguing exercise protocol inhibited the elevation of the plasmatic levels of some cytokines. The running exercise protocol could elevate the circulating levels of IL-2 (from 49.7 to 59.3 pg/mL), TNF-α (from 48.5 to 51.5 pg/mL), INF (from 128.8 to 165.0 pg/mL), IL-6 (from 63.1 to 77.3 pg/mL), and IL-10 (from 48.9 to 59.6 pg/mL) 1 h after the end of the running protocol. However, the curcumin and piperine supplementation could inhibit this elevation. Conclusions: curcumin and piperine supplementation had no effect on physical performance, immune cell counts, or muscle damage; however, the supplementation could modulate the kinetics of IL-2, TNF-α, INF, IL-6, and IL-10 1 h after the end of exercise.9E1A-F9DD-3EB8 | Filipe Manuel ClementeN/

CORRELAÇÃO ENTRE FIBROEDEMAGELÓIDE E DOSAGEM DE ESTRADIOL

Introdução: O fibroedemagelóide (FEG) é considerado antiestético, de caráter multifatorial causando um mau funcionamento do sistema circulatório e das transformações do tecido conjuntivo, podendo resultar em dor local e até mesmo diminuição das atividades funcionais. O estrógeno influência de forma significativa no surgimento do FEG, pois ele pode modificar o equilíbrio das proteoglicanas e glicosaminoglicanas na substância fundamental amorfa. Objetivo: Avaliar a relação entre a dosagem de estradiol e o grau de acometimento do fibroedemagelóide. Métodos: Trata-se de uma pesquisa observacional descritivo, a amostra foi composta por 40 indivíduos do sexo feminino, com faixa etária entre 17 e 45 anos de idade. A avaliação foi realizada através do PAFEG (validado) para análise do grau e forma clínica do FEG e também foi realizado exame da dosagem de estradiol na fase ovulatória de cada participante, ou seja, no 14º dia de um ciclo menstrual de 28 dias. Resultados: Os valores de normalidade do estradiol nessa fase variam entre 49 a 450 pg. Os resultados encontrados foram baseados nos valores da média da dose de estradiol de cada grupo: 250,37 para o grupo de FEG grau 1, 241,48 para o grupo de FEG grau 2 e 178,34 pg para o grupo de grau 3, portanto, os valores de estradiol estão dentro da faixa de normalidade, independente do grau do FEG. De acordo com estes dados foi possível avaliar que uma correlação negativa entre dosagem de estradiol com o grau do fibroedemagelóide (p= 0,032) e com a idade (p= 0,046) esta correlação foi positiva e significativa. Conclusão: A verificação da falta de uma relação entre o FEG e os níveis de estradiol pode ser justificada pelo caráter multifatorial da celulite, bem como a influência desse hormônio nas adaptações do tecido adiposo e conjuntivo e os sistemas circulatório e linfático

ATIVIDADE FÍSICA EM CASA/PARQUES/ACADEMIAS AO AR LIVRE

Estimulo para criação de rotina de exercicio fisico, criação de habito para atividade fisica.A adoção de um estilo de vida ativo por parte da pessoa idosa, proporciona diversos benefícios à saúde, uma vez que é considerado como um importante componente para a melhoria da qualidade de vida e da independência funcional do idoso. Comprovadamente a prática regular de atividades físicas contribuem não somente para a qualidade de vida dos idosos, como pode proporcionar melhora em quadros de depressão, contribui para melhora da cognição e pode favorecer ainda as relações sociais. Sendo assim, esta atividade tem o objetivo de contribuir com a educação em saúde, buscando incentivar a criação de uma rotina de exercícios benéficos à saúde da pessoa idosa, demonstrando a importância da criação de hábitos relativos à prática de atividades físicas e o cuidado com a própria saúde

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis). Time period: Tree-inventory plots established between 1934 and 2019. Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests. Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types
