Pelo fio do nome: relações transnacionais no processo de provimento material do Ginásio Paranaense (1892-1906)

This text uses aspects from Master’s and Doctoral studies situated in the debates about the provision of school material, history of education, and a transnational approach. Following the onomastic method of Carlo Ginzburg (1991), through the thread of names, we understand the subjects involved in the process of supplying and manufacturing the school furniture of Ginásio Paranaense in the late 19th century and early 20th century. Thus, the work aims to identify and map the transnational references in the consumption of artifacts targeting secondary education, checking the needs imposed and how they were fulfilled. The documental sources are newspaper articles consulted at the Hemeroteca Digital da Biblioteca Nacional; reports and documents of governamental representatives, consulted at the Departamento de Arquivo Público Paranaense. Furthermore, we used icographic sources found in the archive of Colégio Estadual do Paraná and minutes from the Museu Maçônico do Paraná. Our theoretical base was the contributions of Serge Gruzinski (2001) regarding the international and intercontinental connections in the process of historic research; Eugenia Roldán Vera and Eckhardt Fuchs (2019) with the discussion on transnational history in the educational sphere; and Cynthia Greive Veiga (2018) to understand the existing margins between schools needs and how they were answered.Este texto utiliza-se de aspectos provenientes da pesquisa realizada no âmbito do curso de mestrado, bem como no de doutorado, situada nos debates sobre o provimento material escolar, a história da educação e a abordagem transnacional. Na esteira do método onomástico de Carlo Ginzburg (1991), com o fio do nome, foi encontrada uma maneira de apreender os sujeitos envolvidos no processo de suprimento e fabricação dos móveis escolares destinados ao Ginásio Paranaense em fins do século XIX e início do XX. Desse modo, este trabalho tem como objetivo identificar e mapear as referências transnacionais no processo de consumo dos artefatos dirigidos ao ensino secundário, averiguando quais necessidades eram postas e como eram satisfeitas. A empiria documental corresponde a artigos de jornais consultados por meio da Hemeroteca Digital da Biblioteca Nacional; relatórios e ofícios de representantes governamentais, consultados no Departamento de Arquivo Público Paranaense; além de fontes iconográficas encontradas no acervo do Colégio Estadual do Paraná e atas do Museu Maçônico do Paraná. O trabalho tem como arcabouço teórico as contribuições de Serge Gruzinski (2001) no que se refere às conexões internacionais e intercontinentais no processo da investigação histórica; Eugenia Roldán Vera e Eckhardt Fuchs (2019) com a discussão sobre a história transnacional no âmbito educacional; e Cynthia Greive Veiga (2018) para compreender as margens existentes entre as necessidades da escola e como estas são atendidas

Pistas e indícios: uma investigação sobre o processo de aquisição mobiliar da escola primária (1884-1894)

Na esteira do paradigma indiciário de Carlo Ginzburg (1989), encontramos nas pistas e nos pormenores uma forma de interpretar e investigar a escola primária paranaense do século XIX. Por esta razão, este artigo tem como objetivo entender como ocorreu o processo de aquisição de móveis escolares para a escola primária paranaense. A empiria documental corresponde a artigos de jornais, leis, decretos e regulamentos da legislação escolar, cartas e iconografia, bem como relatórios e ofícios de professores, inspetores e presidentes da província do Paraná que estiveram presentes na troca de correspondência governamental no século XIX. Como resultados, percebemos que existiram diferentes modos de ser da escola primária durante o século XIX, o que culminou em formas distintas de supri-la materialmente.Palavras-chave: Cultura material escolar.

For this reason, this article aims to understand how the process of buying school furniture for the primary school of Paraná took place. The documentary empiricism corresponds to newspaper articles, laws, decrees and regulations of school legislation, letters and iconography, as well as reports and letters from teachers, inspectors, and presidents of the province of Paraná, who were present in the exchange of government correspondence in the 19th century. As a result, we realize that there were different ways of being of the primary school during the 19th century, which culminated in different ways of supplying it materially.Keywords: School material culture.

Environmental modulation of the proteomic profiles from closely phylogenetically related populations of the red seaweed Plocamium brasiliense

The genus Plocamium encompasses seaweeds that are widely distributed throughout the world’s oceans, with Plocamium brasiliense found along the tropical and subtropical coasts of the Western Atlantic. This wide distribution can lead to structured populations due to environmental differences (e.g., light levels or temperature), restricted gene flow, and the presence of cryptic species. Abiotic variation can also affect gene expression, which consequently leads to differences in the seaweeds protein profile. This study aimed to analyze the genetic and proteomic profiles of P. brasiliense sampled in two geographically distinct sites on the coastline of Rio de Janeiro state, Brazil: Arraial do Cabo (P1) and Búzios (P2). The genetic profiles of macroalgal specimens from these two sites were indistinguishable as assessed by the markers UPA/23S, rbcL, and COI-5P; however, the protein profiles varied significantly between populations from the two sites. At both sites the ribulose-1,5-biphosphate carboxylase/oxygenase was the most abundant protein found in P. brasiliense specimens. The number of phycobiliproteins differed between both sites with the highest numbers being found at P1, possibly due to water depth. The differences in proteomic profiles of the two nearly identical populations of P. brasiliense suggest that environmental parameters such as light availability and desiccation might induce distinct protein expression, probably as a result of the phenotypic plasticity within this population of seaweed

Diversity and antimicrobial potential of culturable heterotrophic bacteria associated with the endemic marine sponge Arenosclera brasiliensis

Marine sponges are the oldest Metazoa, very often presenting a complex microbial consortium. Such is the case of the marine sponge Arenosclera brasiliensis, endemic to Rio de Janeiro State, Brazil. In this investigation we characterized the diversity of some of the culturable heterotrophic bacteria living in association with A. brasiliensis and determined their antimicrobial activity. The genera Endozoicomonas (N = 32), Bacillus (N = 26), Shewanella (N = 17), Pseudovibrio (N = 12), and Ruegeria (N = 8) were dominant among the recovered isolates, corresponding to 97% of all isolates. Approximately one third of the isolates living in association with A. brasiliensis produced antibiotics that inhibited the growth of Bacillus subtilis, suggesting that bacteria associated with this sponge play a role in its health

Abrolhos Bank Reef Health Evaluated by Means of Water Quality, Microbial Diversity, Benthic Cover, and Fish Biomass Data

The health of the coral reefs of the Abrolhos Bank (southwestern Atlantic) was characterized with a holistic approach using measurements of four ecosystem components: (i) inorganic and organic nutrient concentrations, [1] fish biomass, [1] macroalgal and coral cover and (iv) microbial community composition and abundance. The possible benefits of protection from fishing were particularly evaluated by comparing sites with varying levels of protection. Two reefs within the well-enforced no-take area of the National Marine Park of Abrolhos (Parcel dos Abrolhos and California) were compared with two unprotected coastal reefs (Sebastião Gomes and Pedra de Leste) and one legally protected but poorly enforced coastal reef (the “paper park” of Timbebas Reef). The fish biomass was lower and the fleshy macroalgal cover was higher in the unprotected reefs compared with the protected areas. The unprotected and protected reefs had similar seawater chemistry. Lower vibrio CFU counts were observed in the fully protected area of California Reef. Metagenome analysis showed that the unprotected reefs had a higher abundance of archaeal and viral sequences and more bacterial pathogens, while the protected reefs had a higher abundance of genes related to photosynthesis. Similar to other reef systems in the world, there was evidence that reductions in the biomass of herbivorous fishes and the consequent increase in macroalgal cover in the Abrolhos Bank may be affecting microbial diversity and abundance. Through the integration of different types of ecological data, the present study showed that protection from fishing may lead to greater reef health. The data presented herein suggest that protected coral reefs have higher microbial diversity, with the most degraded reef (Sebastião Gomes) showing a marked reduction in microbial species richness. It is concluded that ecological conditions in unprotected reefs may promote the growth and rapid evolution of opportunistic microbial pathogens

Busca de novas drogas antimicrobianas a partir de vegetais

Como parte de um programa que visa o descobrimento de produtos naturais bioativos, 48 extratos metanólicos provenientes de 41 plantas medicinais utilizadas tradicionalmente no Brasil, a maioria delas para o tratamento de doenças associadas a microorganismos, foram avaliadas quanto a sua atividade antibacteriana. O método de difusão em ágar foi utilizado para Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella enterica sorovar typhimurium, Shigella sonnei, Klebsiella pneumoniae, Escherichia coli, Bacillus cereus. Análise fitoquímica dos extratos para a identificação dos principais grupos de fitoconstituintes também foi relatada. Todos os extratos apresentaram atividade antibacteriana contra B.cereus e P. aeruginosa. A maior zona de inibição foi observada para Mitracarpus frigidus. A análise fitoquímica dos extratos demonstrou a presença de fitoconstituintes como taninos, cumarinas, flavonóides, saponinas e alcalóides. Os resultados são promissores visto que todas as plantas selecionadas parecem possuir substâncias antibacterianas. Isto reforça o conceito de que a investigação etnobotânica de plantas pode revelar um número substancial de respostas positivas em ensaios de triagem realizados in vitro

Data from: Metaproteomics reveals metabolic transitions between healthy and diseased stony coral Mussismilia braziliensis

Infectious diseases such as white plague syndrome (WPS) and black band disease (BBD) have caused massive coral loss worldwide. We performed a metaproteomic study on the Abrolhos coral Mussismilia braziliensis to define the types of proteins expressed in healthy corals compared to WPS- and BBD-affected corals. A total of 6363 MS/MS spectra were identified as 361 different proteins. Healthy corals had a set of proteins that may be considered markers of holobiont homoeostasis, including tubulin, histone, Rab family, ribosomal, peridinin–chlorophyll a-binding protein, F0F1-type ATP synthase, alpha-iG protein, calmodulin and ADP-ribosylation factor. Cnidaria proteins found in healthy M. braziliensis were associated with Cnidaria–Symbiodinium endosymbiosis and included chaperones (hsp70, hsp90 and calreticulin), structural and membrane modelling proteins (actin) and proteins with functions related to intracellular vesicular traffic (Rab7 and ADP-ribosylation factor 1) and signal transduction (14-3-3 protein and calmodulin). WPS resulted in a clear shift in the predominance of proteins, from those related to aerobic nitrogen-fixing bacteria (i.e. Rhizobiales, Sphingomonadales and Actinomycetales) in healthy corals to those produced by facultative/anaerobic sulphate-reducing bacteria (i.e. Enterobacteriales, Alteromonadales, Clostridiales and Bacteroidetes) in WPS corals. BBD corals developed a diverse community dominated by cyanobacteria and sulphur cycle bacteria. Hsp60, hsp90 and adenosylhomocysteinase proteins were produced mainly by cyanobacteria in BBD corals, which is consistent with elevated oxidative stress in hydrogen sulphide- and cyanotoxin-rich environments. This study demonstrates the usefulness of metaproteomics for gaining better comprehension of coral metabolic status in health and disease, especially in reef systems such as the Abrolhos that are suffering from the increase in global and local threatening events
