Tudo outra vez: a experimentação de uma webcomic multimídia

This is the descriptive memorial of the experimental project "Tudo Outra Vez: an experimental Multimedia Webcomic" which aims to start as the stages of production of the multimedia’s webcomic project, from its conception, passing through the scripting and its processes - which includes all the research to which it is linked -, and reaching the final product, which involves audiovisual pre-production, production and post-production. The experiment carried out for the conclusion of the Radio, TV and Internet course at the Federal University of Juiz de Fora, explores the narrative and multimedia possibilities of the comics format in a convergent and participatory culture, mentioning authors who address the theme of stories in comics, multimedia fictional narratives and Convergence Culture. The object was selected after observing that the potential of the comic book format was underexplored on the Internet, containing a gap to be filled. This work has the intent, in addition to experimenting the webcomic format, to rescue stories of women who disappeared during the brazilian Military Dictatorship. For this purpose, we made a bibliographical and documental research were carried out to find real accounts of that period in order to build a collection of letters that blend with the fictional letters of history.Este é o memorial descritivo do projeto experimental “Tudo Outra Vez: a experimentação de uma webcomic multimídia” que tem como objetivo detalhar as etapas de produção do projeto de experimentação da webcomic multimídia, desde a sua concepção, passando pela roteirização e seus processos – que incluem toda pesquisa à qual está atrelada –, chegando ao produto final, que envolve pré-produção, produção e pós-produção audiovisual. O experimento, feito para a conclusão do curso de Rádio, TV e Internet da Universidade Federal de Juiz de Fora, explora as possibilidades narrativas e multimidiáticas do formato história em quadrinhos em uma cultura convergente e participativa, mencionando autores que abordam a temática das histórias em quadrinhos, narrativas ficcionais multimidiáticas e Cultura da Convergência. O objeto foi selecionado após observarmos que o potencial do formato história em quadrinho era pouco explorado na Internet, havendo uma lacuna a ser preenchida. Com o trabalho, pretende-se, para além da experimentação do formato de webcomic, resgatar histórias de mulheres que desapareceram durante a Ditadura Militar brasileira. Para isso, foram feitas pesquisas bibliográficas e documentais para encontrar relatos reais daquele período com o intuito de construir um acervo de cartas que se mesclem com as cartas ficcionais da história

Anti-Diabetic Effects of the Ethyl-Acetate Fraction of Trichilia catigua in Streptozo-tocin-Induced Type 1 Diabetic Rats

Background/Aims: Trichilia catigua A. Juss., known as “catuaba” in Brazil, has been popularly used as a tonic for fatigue, impotence and memory deficits. Previously, our group demonstrated that the ethyl-acetate fraction (EAF) of T. catigua has antioxidant and anti-inflammatory effects. The present study evaluated the anti-diabetic activity of EAF in type 1 diabetic rats. Methods: Male Wistar rats were divided into four groups (N: non-diabetic group, D: type 1 diabetic group, NC: non-diabetic + EAF group and DC: type 1 diabetic + EAF group). The latter two groups were treated with 200 mg/kg EAF. Type 1 diabetes was induced by intravenous streptozotocin (STZ) injection (35 mg/kg). Starting two days after STZ injection, EAF was administered daily by gavage for 8 weeks. Results: EAF attenuated body mass loss and reduced food and water intake. EAF improved hyperglycaemia and other biochemical parameters, such as alkaline phosphatase (ALP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Furthermore, the number of pancreatic β-cells and the size of the islets had increased by β-cell proliferation in the DC group. EAF promoted reduction in kidney tissue damage in STZ-induced diabetic rats by reduction of renal fibrosis. Conclusion: The present study showed that EAF improves glucose homeostasis and endocrine pancreas morphology and inhibits the development of diabetic nephropathy in STZ-induced diabetic rats

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
