Educação Popular e Universidade: vivências a partir da extensão, pesquisa e ensino

Este livro é um apanhado histórico, mas atual. É uma reunião de relatos, textos, reflexões, processos, partilhas, que versam sobre nosso sonho de construir uma educação libertadora, um mundo de liberdade. Ainda há muito que ser construído e o caminho é árduo, não temos dúvida. A verdadeira práxis revolucionária não se nutre de seres apenas caminhantes, mas de seres que se envolvem com o caminhar, que são capazes de mudar, mudando a si mesmos também. Somos indivíduos sociais e pintamos o quadro da vida em múltiplas linguagens. É por isso que este livro também carrega diferentes apostas acadêmico-estético-políticas. Por meio de fotografias, poesias, relatos, ensaios e reflexões teóricas, olhares que abordaram com muito carinho e rigor o universo do PET Educação Popular. Foi escrito por várias mãos que constituíram a trajetória do grupo nas diversidades humanas (relações de sexo/gênero), étnico-raciais (negros, indígenas, imigrantes, nordestinos, pobres em geral) e de classes sociais. Combate-se assim, nas ações concretas, as desigualdades sociais, de sexo/gênero, étnico-racial etc, o patriarcado, machismo, LGBTQIA+fobia, o racismo e o capitalismo, a falta de democracia, de liberdade, que outrora iluminaram a modernidade do Capital.Ministério da Educação (MEC

Study of the circulation dynamic of rotavirus sample through their electropherotypes

An epidemiological study was carried out to detect rotavirus associated with cases of acute childhood diarrhea and to observe the circulation dynamics of these viruses on the basis of the electrophoresis profiles of the samples. The fecal specimens were obtained from 0-5-year-old children during 2005 and 2006. Among 55 positive samples detected through an immunoenzymatic test, which were subjected to the technique of electrophoresis in gel of polyacrylamide, it was possible to define the electrophoresis profile of 37 (62 %), with eight distinct profiles observed, all compatible with rotavirus of group A. This allowed the study of the profiles to accompany the dynamics of their circulation, showing that in 2005, all the samples presented long profiles, so-called L1 to L4. Samples of profile L2 appeared in the May and predominated up to August, being substituted by samples of profile L1 and L4 which co-circulated in September. In 2006, a few samples of long profile (L1 and L2) were detected, completing a total of 14 % (3/22), which circulated in May and June. Most of the positive samples of this year (86 % = 19/22) presented short profiles, substituting for those of long profile, from July. The co-circulation of samples with different short and long profiles reveals the extensive genetic variability which the rotavirus can present, within the same period.KEYWORDS: Diarrhea. Rotavirus.

The role of human adenoviruses type 41 in acute diarrheal disease in Minas Gerais after rotavirus vaccination

Abstract Human adenovirus species F (HAdV-F) type 40 and 41 are commonly associated with acute diarrheal disease (ADD) across the world. Despite being the largest state in southeastern Brazil and having the second largest number of inhabitants, there is no information in the State of Minas Gerais regarding the role of HAdV-F in the etiology of ADD. This study was performed to determine the prevalence, to verify the epidemiological aspects of infection, and to characterize the strains of human adenoviruses (HAdV) detected. A total of 377 diarrheal fecal samples were obtained between January 2007 and August 2011 from inpatient and outpatient children of age ranging from 0 to 12 years. All samples were previously tested for rotavirus, norovirus, and astrovirus, and 314 of 377 were negative. The viral DNA was extracted, amplified using the polymerase chain reaction and the HAdV-positive samples were sequenced and phylogenetically analyzed. Statistical analyses were performed using the Chi-square test (p < 0.05), considering two conditions: the total of samples tested (377) and the total of negative samples for the remaining viruses tested (314). The overall prevalence of HAdV was 12.47% (47/377); and in 76.60% (36/47) of the positive samples, this virus was the only infectious agent detected. The phylogenetic analysis of partial sequences of 32 positive samples revealed that they all clustered with the HAdV-F type 41. The statistical analysis showed that there was no correlation between the onset of the HAdV infection and the origin of the samples (inpatients or outpatients) in the two conditions tested: the total of samples tested (p = 0.598) and the total of negative samples for the remaining viruses tested (p = 0.614). There was a significant association in the occurrence of infection in children aged 0&#8211;12 months for the condition 1 (p = 0.030) as well as condition 2 (p = 0.019). The occurrence of infections due to HAdV did not coincide with a pattern of seasonal distribution. These data indicate the significant involvement of HAdV-F type 41 in the etiology of ADD in Minas Gerais, which demonstrates the importance of other viral agents in the development of the disease after the introduction of rotavirus vaccine immunization

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
