11. Os conhecimentos tradicionais Paĩ Tavyterã, Kaiowá e Guarani sobre o ka’a he’ẽ (Stevia rebaudiana)

Author

Felipe Vianna M. Almeida and Marcos Glauser Ortiz

Abstract

Este artigo descreve os conhecimentos tradicionais relacionados ao uso e manejo da Stevia rebaudiana pelos Paĩ Tavyterã, habitantes do departamento de Amambay, no leste do Paraguai, e dos Kaiowa e Guarani, do sul do estado brasileiro do Mato Grosso do Sul. Esses indígenas, conhecem essa planta pela denominação ka’a he’ẽ, em guarani. Por meio da realização de duas pesquisas interculturais, realizadas no Brasil e Paraguai, são descritos os usos relatados por anciões e anciãs com o ka’a he’ẽ, incluindo conhecimentos ecológicos e o manejo da planta. O ka’a he’ẽ, além de ser utilizado como um remédio para a cura de vários males, e como um edulcorante de alimentos, era consumido por jovens, mulheres e homens, na fase de transição para a idade adulta, momento no qual seus corpos se tornavam especialmente vulneráveis a influências externas. Nesse contexto, o consumo de folhas de ka’a he’ẽ, e a aplicação de infusão das folhas em partes do corpo, contribuía com a capacidade de produzir ou extrair alimentos doces, tal como o kaguĩ (chicha) doce, pelas mulheres. Além de produzir a capacidade de tornar algo doce, o ka’a he’ẽ atuava de forma protetiva, moderando e controlando os poderes de alteração dos corpos dos jovens durante a fase de jekoaku na transição para a fase adulta, espantando seres cujas afecções ao corpo não são desejadas. A planta era usada em especial no ritual do kunumi pepy, logo antes da furação dos lábios inferiores dos meninos para a inserção do tembetá.

Abstract

Brazil is one of the largest exporters of cattle meat production. Most of this production is under pasture areas, with different levels of livestock and field management. Remotely sensed images could be interesting tools to detect distinct temporal and spatial patterns of these systems. In this context, classification algorithms have been proposed to use information from satellite images to map different land covers. The Time-Weighted Dynamic Time Warping (TWDTW) is an algorithm that has the advantage of working well with datasets with enough amounts of temporal information and seasonality patterns. In the present work, the TWDTW was performed to classify pasture managements in farms located in Western region of São Paulo State in Brazil for the years 2017 and 2018, as a primary study. It was used Normalized Difference Vegetation Index (NDVI) time series images from Moderate Resolution Imaging Spectroradiometer – MODIS sensor (products MOD13Q1 and MYD13Q) with 250 meters of spatial resolution. In classifications for the years 2017 and 2018, it was observed a predominance of traditional pasture. Total areas of degraded and traditional pasture were very similar between 2017 and 2018. The year of 2017 showed higher spatial distribution of intensified pastures than year 2018. The classification achieved satisfying results with complete accuracy in validation. The information collected from field visits were important to analyse general aspects of the results. Therefore, in this pilot study TWDTW algorithm demonstrated to have potential in differentiating classes of pasture management. Next steps will be to explore the possibilities to classify pasture systems in large areas.

No. of bitstreams: 1 2017 - Marcio de Albuquerqe Vianna.pdf: 5053001 bytes, checksum: d14c9d134edb446ef52873449a846c15 (MD5) Previous issue date: 2017-03-29 CAPES - Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior The study discusses the weakening of family agriculture in Serop?dica-RJ, whose major socioeconomic transformations occurred in the last two decades. Because it is a municipality near the capital of the state and the port region of Itagua? and that, despite having a history of silk production in the 19th century, with rural settlements in the 20th century and with the installation of a knowledge production center in Agriculture, has shown a decrease in rural activity, resulting in the exodus, which could jeopardize food security. In this scenario, the following assumptions are presented: (a) economic growth in the region is perceived as a threat to the loss of Serop?dica's rural identity; (b) communicative action in the interaction of family farmers with local public authorities in municipal councils, together with the poles of educationa,l research and extension institutions of the area, can be a means to promote the strengthening of rural activity; (c) the organization in farmers' associations may favor the search for a substantive rationality capable of building a strong power field in which families participate in the political decisions of the State and interact more significantly with the research and extension entities. The objectives described are: (i) to identify the main laws, public policies, studies and previous programs focused on local rural development; (ii) identify the main actors who propose territorial development actions to recognize the fields of power; (iii) to verify how communicative action, interdependence and interactions of farmers with the public power and the research and extension institutions of the place occur; (iv) to verify if there is a tendency of preservation and strengthening of the activity by the empowerment of groups of families structured in associations that seek a substantive rationality based on the principles of agroecology when valuing the traditional knowledge constructed and diffused locally. The methodological procedures of qualitative and exploratory approach adopted an analysis of the documents of laws, programs and projects directed to family agriculture; It is an ethnographic research that conducted semistructured interviews with local actors. At the same time, there was a participant observation with registration of the issues dealt with in the meetings of the municipal councils and the territorial collegiate. There were difficulties in the permanence of the families of the farmers due to the current socioeconomic and environmental transformations, as well as the poor participation in the articulations discussed in the municipal councils on the necessity of inclusion of the farmers in projects of research and extension for the inclusion in the public policies aiming their fortification. It was also observed a tendency of resistance by the permanence of local productive arrangements of organic farmers who counted in the past with the support of research and extension in agroecology, but in punctual, discontinuous and disjointed projects between the institutions that make up the knowledge production. , Which shows great contradiction. However, there have been recently the implementation of integrative projects with this pole, even at an embryonic stage, that seek to focus on alternative markets, inclusion in public policies and valorization of local knowledge based on agroecology. It is worrying the socioeconomic reproduction of families to resist the process of real estate speculation in the region. However, Serop?dica presents a great potential for the creation of strong ties, as it happens in associations in networks with greater participative governance, that defend their rights of citizenship and fight for the environmental, social and economic sustainability, for the access to public policies. Fair, inclusive and egalitarian in the municipality O estudo discute o enfraquecimento da agricultura familiar em Serop?dica-RJ, cujas grandes transforma??es socioecon?micas ocorreram nas duas ultimas d?cadas. Por se tratar de um munic?pio pr?ximo da capital do estado e da regi?o portu?ria de Itagua? e que, apesar de possuir hist?rico de produ??o da seda no s?culo XIX, com assentamentos rurais no s?culo XX e com a instala??o de um polo de produ??o de conhecimento em agropecu?ria no local, mostra diminui??o da atividade rural, resultando no ?xodo, o que pode comprometer a seguran?a alimentar. Nesse cen?rio s?o apresentadas as suposi??es: (a) o crescimento econ?mico na regi?o ? percebido como uma amea?a ? perda da identidade rural de Serop?dica; (b) a a??o comunicativa na intera??o de agricultores familiares com os poderes p?blicos locais nos conselhos municipais juntamente com o polo de institui??es de ensino, pesquisa e extens?o do local, pode ser um meio de promover o fortalecimento da atividade rural; (c) a organiza??o em associa??es de agricultores pode favorecer a busca por uma racionalidade substantiva capaz de construir um campo de poder forte, no qual as fam?lias participem das decis?es pol?ticas estatais e interajam mais significativamente com as entidades de pesquisa e extens?o. Os objetivos delineados s?o: (i) identificar as principais leis, pol?ticas p?blicas, estudos anteriores e programas voltados para o desenvolvimento rural local; (ii) identificar os principais atores que prop?em a??es de desenvolvimento do territ?rio, a fim de reconhecer os campos de poder; (iii) verificar como se d? a a??o comunicativa, a interdepend?ncia e as intera??es dos agricultores com o poder p?blico e com as institui??es de pesquisa e extens?o do local; (iv) verificar se h? a tend?ncia de preserva??o e fortalecimento da atividade pelo empoderamento de grupos de fam?lias estruturados em associa??es que buscam uma racionalidade substantiva com base nos princ?pios da agroecologia ao valorizar os conhecimentos tradicionais constru?dos e difundidos localmente. Os procedimentos metodol?gicos de abordagem qualitativa e de car?ter explorat?rio adotaram an?lise dos documentos de leis, programas e projetos para a agricultura familiar; ? uma pesquisa etnogr?fica que realizou entrevistas semiestruturadas com atores do local. Houve a observa??o participante com registro das quest?es abordadas nas reuni?es dos conselhos municipais e do colegiado territorial. Verificou-se dificuldades de perman?ncia de agricultores devido ?s transforma??es socioecon?micas e ambientais atuais, assim como a fraca participa??o nas articula??es discutidas nos conselhos municipais acerca da necessidade da inclus?o dos agricultores em projetos de pesquisa e extens?o para inclus?o nas pol?ticas p?blicas visando o seu fortalecimento. Percebeu-se tamb?m uma tend?ncia de resist?ncia de arranjos produtivos locais de agricultores org?nicos que contou no passado com o apoio de pesquisas e extens?o em agroecologia, por?m em projetos pontuais, descont?nuos e desarticulados entre as institui??es que comp?em o polo, o que evidencia grande contradi??o. Entretanto, h? recentemente a implanta??o de projetos integradores com o referido polo, ainda que em est?gio embrion?rio, que buscam focar nos mercados alternativos, na inclus?o em pol?ticas p?blicas e na valoriza??o do conhecimento local baseado na agroecologia. ? preocupante a reprodu??o socioecon?mica das fam?lias para que resistam ao processo de especula??o imobili?ria vigente na regi?o. Entretanto, Serop?dica apresenta um grande potencial para a cria??o de la?os fortes como ocorre nas associa??es em redes com maior governan?a participativa, as quais defendem os seus direitos de cidadania e lutam pela sustentabilidade ambiental, social e econ?mica, pelo acesso ?s pol?ticas p?blicas e por uma sociedade mais justa, inclusiva e igualit?ria no munic?pio.

Abstract

Motivation: The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community‐led open‐source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene. Main types of variables included: The database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, the database contains metadata relating to sampling methodology and contextual information about each record. Spatial location and grain: BioTIME is a global database of 547,161 unique sampling locations spanning the marine, freshwater and terrestrial realms. Grain size varies across datasets from 0.0000000158 km² (158 cm²) to 100 km² (1,000,000,000,000 cm²). Time period and grain: BioTIME records span from 1874 to 2016. The minimal temporal grain across all datasets in BioTIME is a year. Major taxa and level of measurement: BioTIME includes data from 44,440 species across the plant and animal kingdoms, ranging from plants, plankton and terrestrial invertebrates to small and large vertebrates. Software format: .csv and .SQL.

Abstract

Motivation: The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene. Main types of variables included: The database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, the database contains metadata relating to sampling methodology and contextual information about each record. Spatial location and grain: BioTIME is a global database of 547,161 unique sampling locations spanning the marine, freshwater and terrestrial realms.

Abstract

Aim: To investigate the effect of magnesium sulphate used as an adjuvant to lidocaine with epinephrine local anaesthetic on the success of inferior alveolar nerve blocks (IANB) in patients with symptoms of irreversible pulpitis undergoing root canal treatment. Methodology: In a double‐blind clinical trial, following power calculation, 124 patients with symptoms of irreversible pulpitis in mandibular molar teeth were selected, and initial pain data were collected using a Heft–Parker (Pain, 19, 1984 and 153) visual analogue scale. The first group (control) received IANB with 1.8 mL of a local anaesthetic solution containing 1.8% lidocaine with 1 : 88 000 epinephrine while the second group (test) received IANB with 1.8 mL of an anaesthetic solution containing 1% magnesium sulphate, and 1.8% lidocaine with 1 : 88 000 epinephrine. Pain data were collected after access cavity and penetration of files in the canals using a Heft–Parker visual analogue scale. Two patients were not included in the study as they did not consent, and a further 54 patients were excluded as they did not report lip numbness within 15 min after IANB administration; thus, the data presented in this study are related to 68 patients. The data were analysed using chi‐square and t‐test (α = 0.05). Results: The success of pulpal anaesthesia with IANB was 82% for the magnesium sulphate group and 53% for the control group. There was a significant difference in the effectiveness of the IANB between the two groups (P < 0.001). There was no significant difference between the magnesium sulphate and control groups regarding gender (P = 0.598) or age (P = 0.208) or initial pain scores (P = 0.431). Conclusions: The addition of 1% magnesium sulphate to 1.8% lidocaine with 1 : 88 000 epinephrine resulted in a positive impact for the success of IANB in patients with a diagnosis of irreversible pulpitis related to mandibular molar teeth undergoing root canal treatment. Thus magnesium sulphate may be used as adjuvant for achieving profound pulpal anaesthesia in challenging cases. However, more studies with larger sample size and different concentration doses must be carried out to establish an appropriate conclusion before its routine clinical use. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Aim: To investigate in situ Enterococcus faecalis biofilm removal from the lateral canal of a simulated root canal system using passive or active irrigation protocols. Methodology: Root canal models (n = 43) were manufactured from transparent resin materials using 3D printing. Each canal was created with an 18 mm length, apical size 30, a .06 taper and a lateral canal of 3 mm length, with 0.3 mm diameter. Biofilms were grown in the lateral canal and apical 3 mm of the main canal for 10 days. Three models from each group were examined for residual biofilm using SEM. The other forty models were divided into four groups (n = 10). The models were observed under a fluorescence microscope. Following 60 s of 9 mL of 2.5% NaOCl irrigation using syringe and needle, the irrigant was either left stagnant in the canal or activated using gutta‐percha, sonic or ultrasonic methods for 30 s. Images were then captured every second using an external camera. The residual biofilm percentages were measured using image analysis software. The data were analysed using generalized linear mixed models. A significance level of 0.05 was used throughout. Results: The greatest level of biofilm removal was obtained with ultrasonic agitation (66.76%) followed by sonic (45.49%), manual agitation (43.97%) and passive irrigation groups (38.67%), respectively. The differences were significant between the residual biofilm in the passive irrigation and both sonic and ultrasonic groups (P = 0.001). Conclusion: Agitation resulted in better penetration of 2.5% NaOCl into the lateral canal of an artificial root canal model. Ultrasonic agitation of NaOCl improved the removal of biofilm.

Abstract

This study determined the spatial and temporal distributions of the silver mojarra Eucinostomus argenteus (Perciformes: Gerreidae), one of the most abundant teleost species in bays and estuaries. Sampling was conducted from July 2005 to June 2007. The species was captured on all sampling dates and at six of the seven sampling stations. Approximately 80% of the individuals were below the size of first sexual maturity (12·0 cm total length, LT). Although the spatial distribution of juveniles and adults differed throughout the study period, the environmental variables measured explained only a small part of their distribution. The recruitment period occurred during the first part of each year. Despite the high pollution levels in Guanabara Bay, this coastal system plays an important role as a nursery ground and for the growth of E. argenteus. [ABSTRACT FROM AUTHOR]

The theoretical foundation is based on Ethnomathematics, Decolonial Pedagogy and Liberating Pedagogy. The research methods and techniques used were: semi-structured interviews, participant observation, field diary and document analysis. The study reflects on the existence of an appreciation of knowledge, remnants of the remnants of Marambaia through local crafts, and by the school. The sought to demonstrate that this knowledge can dialogue with each other. The main arguments that value each of these types of knowledge, in their own way, and the non-hierarchization between them, can favor and help the process of formation of the local cultural identity. The possibilities of articulation between the practices of the local culture and the mathematical knowledge are immense, however, it is necessary to be willing to listen to the voices, the stories and the feelings of the group with which one works. The central problem of this research is how Ethnomathematics can contribute to this process, approaching the practice of handicrafts, produced by local residents, and a proposal for a didactic sequence that allows students to also participate in an investigative process. Finally, the main variables of local research are identity, culture, knowledge and crafts.

A fundamenta??o te?rica ? baseada na Etnomatem?tica, Pedagogia Decolonial e a Pedagogia Libertadora. Os m?todos e t?cnicas de pesquisas utilizados foram: as entrevistas semiestruturadas, a observa??o participante, o di?rio de campo e a an?lise documental. O estudo reflete sobre a rela??o existente entre a valoriza??o dos conhecimentos populares, produzidos pelos remanescentes quilombolas na Ilha da Marambaia por meio do artesanato local, e os conhecimentos acad?micos, ensinados pela escola. A pesquisa buscou demonstrar que esses conhecimentos podem dialogar entre si. Os argumentos principais s?o que a valoriza??o de cada um desses saberes, ? sua maneira, e a n?o hierarquiza??o entre eles, pode favorecer e auxiliar o processo de forma??o da identidade cultural local. As possibilidades de articula??o entre as pr?ticas da cultura local e o conhecimento matem?tico s?o imensas, por?m, ? preciso estar disposto a ouvir as vozes, as hist?rias, as lutas e os sentimentos do grupo com o qual se trabalha.

Abstract

A incid?ncia da doen?a de Alzheimer (DA) vem aumentando consideravelmente e as pr?ticas terap?uticas estabelecidas s?o apenas paliativas. A DA ? caracterizada pela presen?a de placas de beta-amil?ide (A?) e emaranhados neurofibrilares de prote?na Tau. A? ? um pept?deo de tamanhos vari?veis entre 39 e 43 amino?cidos, dos quais A?42 ? o mais patog?nico e abundante em placas e apresenta o maior potencial de agrega??o. As formas oligom?ricas sol?veis de A? tem o potencial de interagir com receptores de membrana e alvos metab?licos levando a falhas sin?pticas, d?ficits cognitivos e morte neuronal enquanto as formas fibrilares tendem a se agregar. A autofagia foi revisada recentemente e atualmente ? sugerida como um processo subjacente associado ? DA. Avaliamos o impacto da inje??o cerebroventricular (cvi) de solu??es de pept?deo A?42 humano em diferentes conforma??es oligom?ricas - monom?ricas, oligom?ricas e fibrilares - no peixe-zebra adulto sobre par?metros comportamentais incluindo ? locomo??o, ansiedade e mem?ria de longo prazo (LTM). A cvi de A?42 causou uma diminui??o significativa na explora??o de um novo tanque no grupo que recebeu a forma fibrilar de A?42 em rela??o ao controle medida atrav?s da redu??o da dist?ncia percorrida e da velocidade m?dia. Os animais que receberam as formas monom?rica e oligom?rica n?o tiveram preju?zo nos par?metros de explora??o, em conjunto, esses dados sugerem uma tend?ncia de redu??o da explora??o. Houve uma redu??o estatisticamente significativa induzida pelo tratamento no n?mero de entradas na zona superior nos grupos mon?mero, olig?mero e fibrila em rela??o aos controles e no tempo gasto na zona superior no grupo mon?mero em rela??o ao grupo controle . Esses par?metros sugerem um leve efeito ansiog?nico de A?42. A mem?ria de longa-dura??o (LTM) para a tarefa de esquiva inibit?ria foi significativamente prejudicada nos grupos tratados com formas sol?veis monom?ricas ou oligom?ricas de A?42. Esses resultados corroboram as evid?ncias de que as formas sol?veis podem ser mais prejudiciais ? cogni??o e ? LTM. Os n?veis cerebrais de LC3, uma prote?na central na via da autofagia amplamente usada como marcador de autofagossomos, tamb?m foram estimados usando western blotting. O imunoconte?do cerebral LC3 foi aumentado em animais que receberam olig?meros e fibrilas de A?42. O aumento de estruturas autof?gicas observado n?o necessariamente indica um aumento no fluxo autof?gico fisiol?gico, ? poss?vel que seja reflexo de uma interrup??o patol?gica no fluxo autof?gico que leva ao ac?mulo de estruturas autof?gicas n?o degradadas e a morte neuronal. Em s?ntese, demonstramos que a cvi de A?42 em diferentes conforma??es oligom?ricas sol?veis reflete em uma tend?ncia sutil a redu??o de locomo??o, aumento do comportamento ansiog?nico, redu??o de LTM e aumento de estruturas autof?gicas no enc?falo do peixe zebra. The incidence of Alzheimer's disease (AD) has increased considerably and the established therapeutic practices remain palliative. AD is characterized by the presence of beta-amyloid (A?) plaques and neurofibrillary tangles of Tau protein. A? is a peptide of varying sizes between 39 and 43 amino acids, of which A?42 is the most pathogenic and abundant in plaques and has the greatest aggregation potential. The soluble oligomeric forms of A? have been shown to have the potential to interact with membrane receptors and metabolic targets leading to synaptic failures, cognitive deficits and neuronal death while fibrillar forms tend to aggregate. Autophagy was recently revised and is currently suggested as an underlying process associated with AD. We assessed the impact of cerebroventricular injection (cvi) of human A?42 peptide solutions in different oligomeric conformations - monomeric, oligomeric and fibrillar - on the behavioral parameters of the adult zebrafish associated with locomotion, anxiety and long-term memory (LTM). A?42 Cvi caused a significant decrease in the exploration of a new tank measured by the reduced distance traveled and the average speed only in the injected fibril group, taken together these results suggest a treatment tendency to reduce exploration. There was a statistically significant treatment-induced reduction in the number of entries in the top zone in the monomer, oligomer and fibril groups in relation to the controls and in the time spent in the top zone in the monomer group in relation to the control group. These parameters suggest a slight anxiogenic effect of A?42.LTM for the inhibitory avoidance test was significantly impaired in groups treated with soluble A?42 monomeric or oligomeric forms, whose memory formation was impaired. These results corroborate the evidence that soluble forms may be more harmful to cognition and LTM. Brain levels of LC3, a central protein in the autophagy pathway widely used as a marker for autophagosomes, were also estimated using western blotting. The cerebral immunocontent LC3 was increased in animals that received oligomers and fibrils, suggesting that oligomers and A?42 fibrils increase the autophagic structures in the brain. The increase in autophagic structures observed does not necessarily indicate an increase in the physiological autophagic flow, it is possible that it is a reflection of a pathological interruption in the autophagic flow that leads to the accumulation of not degraded autophagic structures and neuronal death. In summary, we demonstrated that the c? of A?42 in different soluble oligomeric conformations reflects a subtle tendency to reduce locomotion, increase anxiogenic behavior, reduce LTM and increase autophagic structures in the zebra fish brain.
