Características físicas e químicas da graviola

In this work, fruits from soursoup (Annona muricata L.) obtained in Fortaleza, Ceará, Brazil, were used. Physical measurements were made on the homogenized pulp of raw and ripe fruits to evaluate their industrial yield. Chemical and physical determinations were made in order to know the chemical composition of the fruits. Liquid gas chromatography was used to evaluate the percentage of the fatty acid composition of the lipid fraction of the soursoup seeds.Neste trabalho foram empregados frutos da gravioleira (Annona muricata L.), provenientes do mercado hortifrutigranjeiro de Fortaleza, Ceará. Realizaram-se medidas físicas em 30 frutos maduros. As determinações das características químicas e físicas foram realizadas na polpa homogeneizada de frutos verdes e maduros. Procedeu-se a estudo no óleo da semente da graviola através de análise cromatográfica em fase gasosa, determinando-se a percentagem de ácidos graxos presentes na fração lipídica

O IMPACTO DO USO DE AGROTÓXICO NA AGRICULTURA E OS PROBLEMAS DE SAÚDE PÚBLICA: UMA REVISÃO

In Brazil, the agricultural sector is one of the main bases of the economy, both for agribusiness in the production of commodities for export, and for family farming in food production, both with growth prospects. Due to large exports, food production had to be faster, using pesticides and harming human and environmental health. The objective of this article is to understand the impact that the use of pesticides has on the rural population and the problems that it can cause to public health. This is an integrative literature review study, which used the VHL, LILACS and Medline as the search database. Only ten articles were found, therefore only eight were selected. These studies were published between the years 2018 and 2023. The more exposed to the pesticide, the greater the risk of developing some pathology, be it unidentified poisoning, hematological problems with an insistent cause, cancer, degenerative disease, among other causes.No Brasil, o setor agropecuário é uma das principais bases da economia, tanto pelo agronegócio na produção de commodities para exportação, quanto pela agricultura familiar na produção de alimentos, ambos com perspectiva de crescimento. Devido as grandes exportações, a produção de alimentos teve que ser mais rápida fazendo o uso de agrotóxico e prejudicando a saúde humana e ambiental. O objetivo deste artigo é compreender o impacto que o uso de agrotóxico causa na população rural e os problemas que a mesma pode trazer a saúde pública. Trata-se de um estudo do tipo revisão de literatura integrativa, que teve a BVS, LILACS e Medline, como base de dados de busca.  Foram encontrados apenas dez artigos, portanto apenas oito foram selecionados. Estes estudos foram publicados entre os anos de 2018 a 2023. Quanto mais expostos ao agrotóxico maior será o risco de desenvolver alguma patologia seja uma intoxicação não identificada, problemas hematológicos com causa insistente, câncer, doença degenerativa, entre outras causas

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

Acute kidney injury due to systemic Loxoscelism: a cross-sectional study in Northeast Brazil

Abstract INTRODUCTION: Loxoscelism is a clinical condition involving spiders of the genus Loxosceles. One of the most severe complications is acute kidney injury (AKI). This study aimed to investigate AKI and other complications associated with loxoscelism. METHODS: We analyzed cases diagnosed with loxoscelism in an area where most accidents were caused by Loxosceles amazonica from January 2010 to December 2015. AKI was defined according to the KDIGO criteria. RESULTS: Forty-five patients were recorded: 95.6% presented characteristic necrotic skin lesions and 13.3% AKI. CONCLUSIONS: Loxoscelism could cause kidney involvement which is uncommon and could lead to the death of these patients

Zooterapia popular na Chapada Diamantina: uma medicina incidental? Folk medicine using animals in the Chapada Diamantina: incidental medicine?

Este trabalho analisa o sistema zooterápico tradicional de uma população afrodescendente na Chapada Diamantina, Bahia. A pesquisa foi conduzida ao longo de oito meses de trabalho nos quais foram realizadas entrevistas livres e semi-estruturadas, registro fotográfico e identificação de espécies. Busca-se, além da apresentação de uma lista de produtos oriundos de animais e seus respectivos usos, iniciar uma discussão sobre as possíveis razões para crença no potencial terapêutico ou profilático das frações e produtos animais amplamente utilizados na medicina tradicional de populações brasileiras.<br>This study examines the traditional therapeutic use of animals or parts of animals by an Afro Brazilian population living in the Chapada Diamantina, Bahia, Brazil. The investigation was conducted over a period of eight months and consisted of open- and semi-structured interviews, photographic documentation and identification of species. Besides presenting a list of animal products and their respective use, we seek to stimulate a discussion about the possible existence of a rational basis for the belief in the therapeutic or prophylactic potential of the animal products used in the traditional medicine of Brazilian populations

Psicologia da Religião no Brasil: a produção em periódicos e livros

Apresenta-se apreciação crítica da Psicologia da Religião no Brasil, no período de 1956 a 2005, realizada com base em artigos publicados principalmente em periódicos nacionais de Psicologia.
