    O movimento por justiça ambiental surgiu nos EUA na década de 1970 quando pesquisas revelaram que os resíduos tóxicos eram destinados de forma desproporcional à populações afrodescendentes. A agroecologia, campo de produção científico interdisciplinar, também se consolidou na década de 1970, oriunda da fusão das ciências naturais e sociais, com o propósito de permitir o estilos de agricultura com maiores níveis de sustentabilidade, socialmente justa e economicamente viável. Esse trabalho situa-se no campo da pesquisa teórica, de caráter exploratório sobre as concepções e convergências da área da justiça ambiental e da agroecologia, utilizando-se de uma pesquisa bibliográfica com abordagem qualitativa. Ao fortalecer os modos de vida camponeses, a agroecologia tem contribuído na luta por justiça ambiental. Nesse sentido, podemos perceber a relação entre o movimento agroecológico e o movimento por justiça ambiental, dada suas convergências no objetivo de promover a justiça social.The movement for environmental justice emerged in the US in the 1970s when research revealed that toxic waste was allocated proportional to the Afro-descendant populations. Agroecology, interdisciplinary scientific production field, also consolidated in the 1970s, derived from the fusion of natural and social sciences, in order to allow the farming styles with higher levels of sustainability, socially just and economically viable. This work lies in the field of theoretical research, exploratory on the concepts and similarities of the area of environmental justice and agroecology, using a literature research with qualitative approach. By strengthening livelihoods farmers, agroecology has contributed in the struggle for environmental justice. In this sense, we can see the relationship between agro-ecological movement and the movement for environmental justice, given their convergence in order to promote social justice.Eje A6: Desarrollo Rural, Movimientos Sociales, Estado y AgroecologíaFacultad de Ciencias Agrarias y Forestale

    The Barretos Cancer Hospital Animal Facility (BCHAF) is a unique facility in Brazil exclusively dedicated to working with animal models for cancer research. In this article, we briefly present our modern facility and the main experiments performed, focusing on mutant strains of mice (PTCH-knockout and ApcMin mice), xenograft models, and patient-derived xenografts (PDXs). Our results show the progress and challenges in establishing these models and the need for having an appropriate representation of our cancer population to better understand tumor biology and to identify cancer biomarkers, which could be putatively targeted, allowing for personalized therapy.This study was funded by the Public Ministry of Labor Campinas (Research, Prevention and Education of Occupational Cancer) and by Pio XII Foundation, Barretos Cancer Hospital internal funds, Grant Number: 13/2021

    Objective: To assess mortality during the COVID-19 pandemic according to social vulnerability by areas of Belo Horizonte (BH), aiming at strategies for vaccination. Methods: Ecological study with mortality analysis, according to census tracts classified by the Health Vulnerability Index, a composite indicator that includes socioeconomic and sanitation variables. Deaths due to natural causes and COVID-19 were obtained from the “Mortality Information System”, between the 10th and 43rd epidemiological weeks (EW) of 2020. Excess mortality was calculated by a time series model, considering observed deaths by EW, between 2015 and 2019, for census tracts. Mortality rates (MR) were calculated and age-standardized =using population estimates from 2010 census. Results: Excess mortality in BH was 16.1% (n =1524): 11.0%, 18.8% and 17.3% in the low, intermediate and high vulnerability areas, respectively. The differences between observed and expected age-standardized MR by natural causes were equal to 59/100,000 inhabitants in BH, increasing from 31 to 77 and 95/100,000 inhabitants, in the areas of low, intermediate and high vulnerability, respectively. There was an aging gradient in COVID-19 MR, ranging from 4 to 611/100,000 inhabitants among individuals of 20-39 years and 75+ years. The COVID-19 MR per 100,000 elderly (60+ years) was 292 in BH, increasing from 179 to 354 and 476, in the low, intermediate and high vulnerability areas, respectively. Conclusion: Inequalities in mortality, particularly among the elderly, combined with the limited supply of doses, demonstrate the importance of prioritizing socially vulnerable areas during vaccination against COVID-19.Objetivo: Avaliar a mortalidade por áreas de Belo Horizonte (BH) durante a pandemia de COVID-19 conforme vulnerabilidade social, visando estratégia de vacinação. Métodos: Estudo ecológico com análise de mortalidade, segundo setores censitários classificados pelo Índice de Vulnerabilidade da Saúde, composto por indicadores de saneamento e socioeconômicos. Óbitos por causas naturais e COVID-19 foram obtidos do Sistema de Informação sobre Mortalidade, entre a 10ª e 43ª semana epidemiológica (SE) de 2020. Calculou-se o excesso de mortalidade por modelo de série temporal, considerando as mortes observadas por SE, entre 2015 e 2019, por setor censitário. Taxas de mortalidade (TM) foram calculadas e padronizadas por idade a partir de estimativas populacionais do IBGE. Resultados: Houve 16,1% (n=1524) de excesso de mortalidade em BH: 11,0%, 18,8% e 17,3% nas áreas de baixa, média e elevada vulnerabilidade, respectivamente. As diferenças entre TM observadas e esperadas por causas naturais, padronizadas por idade, foi igual a 59/100.000 habitantes em BH, aumentando de 31 para 77 e 95/100.000, nas áreas de baixa, média e elevada vulnerabilidade, respectivamente. Houve gradiente de aumento com a idade nas TM por COVID-19, variando de 4 a 611/100.000 habitantes entre as idades de 20-39 anos e 75+ anos. A TM por COVID-19 por 100.000 idosos (60+ anos) foi igual a 292, aumentando de 179 para 354 e 476, nos setores de baixa, média e elevada vulnerabilidade, respectivamente. Conclusão: Desigualdades na mortalidade, mesmo entre idosos, aliadas à baixa oferta de doses, demonstram importância de priorizar áreas socialmente vulneráveis durante a vacinação contra COVID-19

    It is an unequivocal fact that Amazonian tropical forest is the largest remaining primary forest in the world. The ecosystem in the region is e tremely comple with high biodiversity (Peres et al. 2010). Conservation and protection of the dynamic forest and river regions is e tremely important not only for the natural environments, but also for the economy and social dependence of benefits from such abundant natural environments. Important natural parameters that affect status of the natural environments include light (natural sunlight), soil, and water, which abundantly e ist in the Amazon region. Solar energy is the primary energy source for the majority of living organisms in both terrestrial and aquatic ecosystems, and drives the diurnal and seasonal cycles of biogeochemical processes (Monteith & Unsworth 2013). In particular, in situ light data remains one of the most underappreciated data measurements although having a significant impact on the physical, chemical and biological processes in the ecosystem (Johnsen 2012). Soil provides the fundamental basis for all terrestrial living organisms including the Amazonian forests as well as life-sustaining infrastructure for human society. Water is the most essential single entity to constitute all organisms from a single cell to the earth. Understanding of importance and roles of each factor and interaction of such comple dynamics in the natural environments can serve as fundamental platform for natural scientists, particularly for young scientists such as university students. The objective of this workshop was to provide hand- on scientific and environmental education for university students in Manaus, Amazonas, Brazil through practical field measurements using the three most important parameters in the natural ecosystem composed of natural sunlight, soil, and water. The workshop was divided into a series of lectures, in situ field sampling, and data processing, analysis and interpretation with the ultimate goal of empowering the undergraduate students with research-centered environmental education and e perience of developing international collaboration.departmental bulletin pape
