Dombrock Genotyping In Brazilian Blood Donors Reveals Different Regional Frequencies Of The Hy Allele.
Dombrock blood group system genotyping has revealed various rearrangements of the Dombrock gene and identified new variant alleles in Brazil (i.e., DO*A-SH, DO*A-WL and DO*B-WL). Because of the high heterogeneity of the Brazilian population, interregional differences are expected during the investigation of Dombrock genotypes. The present study aims to determine the frequencies of Dombrock genotypes in blood donors from Minas Gerais and compare the frequencies of the HY and JO alleles to those of another population in Brazil. The frequencies of the DO alleles in Minas Gerais, a southeastern state of Brazil, were determined from the genotyping of 270 blood donors. Genotyping involved polymerase chain reaction and restriction fragment length polymorphism analysis to identify the 323G>T, 350C>T, 793A>G, and 898C>G mutations, which are related to the HY, JO, DO*A/DO*B, and DO*A-WL/DO*B-WL alleles, respectively. Moreover, the frequencies of rare HY and JO alleles were statistically compared using the chi-square test with data from another Brazilian region. The HY allele frequency in Minas Gerais (2.4%) was almost twice that of the JO allele (1.5%). The frequency of the HY allele was significantly higher (p-value = 0.001) than that in another Brazilian population and includes a rare homozygous donor with the Hy- phenotype. In addition, the DO*A-WL and DO*B-WL alleles, which were first identified in Brazil, were found in the state of Minas Gerais. The data confirm that the frequencies of DO alleles differ between regions in Brazil. The population of Minas Gerais could be targeted in a screening strategy to identify the Hy- phenotype in order to develop a rare blood bank.35400-
CONTRIBUIÇÃO DA EXTENSÃO NA EDUCAÇÃO AMBIENTAL VOLTADA À GESTÃO DE RECURSOS HÍDRICOS
A Educação Ambiental (EA) é essencial para concretizar a gestão dos recursos hídricos numa bacia hidrográfica e a Extensão é o canal de interação dialógica, pois suas ações protagonizam a interação necessária para a troca de saberes (BRASIL, 2007), com desenvolvimento de inter-relações entre universidade, comunidade da bacia e atores sociais envolvidos nesta gestão. A participação social destes atores na gestão descentralizada, integrada e participativa dos recursos hídricos é garantida pelos comitês de bacia, parceiros naturais nas ações de EA. Buscando contribuir para a concretização desta gestão nas bacias dos rios Araranguá e Urussanga, comprometidas na qualidade de suas águas, elaborou-se, em parceria com os comitês destas bacias, o projeto de extensão “A gestão de recursos hídricos nas bacias dos rios Araranguá e Urussanga: conscientização e capacitação de seus atores sociais”, vinculado à Unidade Acadêmica Humanidades, Ciência e Educação (UNA HCE) da Universidade do Extremo Sul Catarinense (UNESC), entidade membro destes comitês. Desenvolvido ao longo dos anos de 2014 e 2015, o projeto teve como objetivo geral planejar, organizar e acompanhar as atividades dos planos de trabalho dos Comitês de bacia dos rios Araranguá e Urussanga. A Educação Ambiental voltada à gestão dos recursos hídricos perpassa a maioria das atividades desenvolvidas pelo projeto, ressaltando-se os cursos de capacitação de atores sociais e comunidade da bacia e os cursos nas escolas dos municípios integrantes da bacia do rio Araranguá, por ser a escola referência importante na comunidade e ter relevante papel na formação das pessoas e no incentivo à cidadania ambiental
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

Trajetórias da Educomunicação nas Políticas Públicas e a Formação de seus Profissionais
Esta obra é composta com os trabalhos apresentados no primeiro subtema, TRAJETÓRIA – Educação para a Comunicação como Política pública, nas perspectivas da Educomunicação e da Mídia-Educação, do II Congresso Internacional de Comunicação e Educação. Os artigos pretendem propiciar trocas de informações e produzir reflexões com os leitores sobre os caminhos percorridos, e ainda a percorrer, tendo como meta a expansão e a legitimação das práticas educomunicativas e/ou mídia-educativas como política pública para o atendimento à formação de crianças, adolescentes, jovens e adultos, no Brasil e no mundo
