O uso e a ocupação das regiões úmidas no Estado do Ceará, intensificou a dinâmica geomorfológica nas Serras úmidas de Uruburetama ao longo dos 973,43 km². Para compreender a organização dos sistemas ambientais aplicou-se a compartimentação geomorfológica e Geossistemica de Bertrand (1968), classificando em unidades inferiores de paisagens em Geofáceis de (Topo, Vertente e Vale) nos quadrantes I e II, com área de 12,43 km². Assim, observou-se nos dados da produção agrícola do milho uma concentração de acidez favorável com pH 6,0 nas áreas de Quadrante I mais concentra em relação ao Quadrante II, propondo-se um zoneamento da paisagem com base nos critérios agrícolas.
Biopólis, necrópolis, ‘blackpolis’: notas para un nuevo léxico político en los análisis socio-espaciales del racismo
Authors: Alves Jaime Amparo
Published: May 2020

Este artículo de reflexión propone algunos conceptos para una agenda de estudios urbanos comprometida con la justicia espacial en dos sociedades de la diáspora africana. Tomando como referencia los patrones de segregación racial en Salvador, Rio de Janeiro, Santiago de Cali y Bogotá, sugiero un nuevo léxico político en los estudios sobre el racismo y sus dimensiones espaciales a partir de los conceptos de bipolis, necrópolis y negrópolis (blackpolis). Sostengo que los referenciales teóricos del “derecho a la ciudad” son importantes pero insuficientes para dar cuenta de la experiencia unica de las gentes negras con las ingeniarías macabras que producen la ciudad multicultural. Negrópolis es, entonces, presentada como una comunidad política alternativa fundada en una ética negra que resignifica lo que entendemos como humanidad, que reorganiza el mundo de la producción y que reconfigura radicalmente el vivir urbano de los condenados y condenadas de la ciudad.
Para valorizar a dimensão da vida cotidiana: articulações ao debate das sustentabilidades
Authors: Martins Gabriel Dos Santos
Published: May 2020

Propomos a valorização da dimensão do cotidiano enquanto enfoque de análise que exerce  importância para o debate que constrói a necessidade de novos padrões de sustentabilidades frente às segregações socioambientais. A discussão ambiental comumemente está relacionada ao privilégio das grandes dimensões, dos grandes eventos (catástrofes) ambientais, relacionadas aos resultados sociais advindos dos mesmos. A supervalorização de tais processos são entendidos, aqui, enquanto produtores de alienações que negam e camuflamam processos de injustiças ambientais promovidas no dia-a-dia. Valorizar o cotidiano, nos embasamentos de Lefebvre e Heller, para a compreensão mais sólida da realidade, se faz de suma importância para entrelaçar redes e propostas de sustentabilidades que privilegiam o plano da vida comum, a autonomia territorial e a participação ativa dos sujeitos.

Published: May 2020

The N6-methyladenosine (m6A) RNA modification is essential during embryonic development of various organs. However, its role in embryonic and early postnatal islet development remains unknown. Mice in which RNA methyltransferase-like 3/14 (Mettl3/14) were deleted in Ngn3+ endocrine progenitors (Mettl3/14nKO) developed hyperglycemia and hypoinsulinemia at 2 weeks after birth. We found that Mettl3/14 specifically regulated both functional maturation and mass expansion of neonatal β-cells before weaning. Transcriptome and m6A methylome analyses provided m6A-dependent mechanisms in regulating cell identity, insulin secretion, and proliferation in neonatal β-cells. Importantly, we found that Mettl3/14 were dispensable for β-cell differentiation but directly regulated essential transcription factor MafA expression at least partially via modulating its mRNA stability. Failure to maintain this modification impacted the ability to fulfill β-cell functional maturity. In both diabetic db/db mice and patients with type 2 diabetes (T2D), decreased Mettl3/14 expression in β-cells was observed, suggesting its possible role in T2D. Our study unraveled the essential role of Mettl3/14 in neonatal β-cell development and functional maturation, both of which determined functional β-cell mass and glycemic control in adulthood.

Diabetes-induced
oxidative stress is one of the major contributors to dysfunction of endothelial
progenitor cells (EPCs) and impaired endothelial regeneration. Thus, we tested
whether increasing antioxidant protein metallothionein (MT) in EPCs promotes
angiogenesis in a hind limb ischemia (HLI) model in endothelial MT transgenic
(JTMT) mice with high fat diet and streptozocin-induced diabetes. Compared with
littermate wild-type (WT) diabetic mice, JTMT diabetic mice had improved blood
flow recovery and angiogenesis after HLI. Similarly, transplantation of JTMT
bone marrow-derived mononuclear cells (BM-MNCs) stimulated greater blood flow recovery
in db/db mice with HLI than did WT
BM-MNCs. The improved recovery was associated with augmented EPC mobilization
and angiogenic function. Further, cultured EPCs from diabetic patients exhibited
decreased MT expression, increased
cell apoptosis and impaired tube formation; while cultured JTMT-EPCs had enhanced cell survival, migration, and tube
formation in hypoxia/hyperglycemic conditions compared with WT-EPCs.
Mechanistically, MT overexpression enhanced hypoxia-inducible factor 1α
(HIF-1α), stromal cell-derived factor (SDF-1) and vascular endothelial growth
factor (VEGF) expression, and reduced oxidative stress in ischemic tissues.
MT’s pro-EPC effects were abrogated by siRNA knockdown of HIF-1α without
affecting MT’s anti-oxidant action. These results indicate that endothelial MT
overexpression is sufficient to protect against diabetes-induced impairment of
angiogenesis by promoting EPC functions most likely through upregulation of
HIF-1α/SDF-1/VEGF signaling and reducing oxidative stress.
