Através da história oral foram entrevistados lideranças e moradores antigos. As entrevistas seguiram um roteiro aberto considerando três eixos: histórias contadas pelos antigos, gênese do movimento quilombola e o significado de quilombo e quilombola. Tendo em vista os discursos dos entrevistados foram discutidos os conceitos de memória, identidade, poder e quilombo.

These new iminopyrrole ligand precursors, designed with increasing bulkiness and different electronic properties, and their corresponding nickel(ii) complexes were characterised by NMR spectroscopy and elemental analysis, and their structural features were analysed by single crystal X-ray diffraction. The nickel complexes were tested as aluminium-free catalysts for the polymerisation of ethylene, at low to moderate pressures and different temperatures and in the absence or presence of the phosphine scavenger [Ni(COD)2], giving rise to catalytic activities in the range of 3.61-73.12 kgPE molNi-1 h-1 bar-1. The polyethylene products formed in these catalytic...

Hypoxia also activates microglia, the myeloid resident cells of the brain parenchyma. Upon activation, microglia release high amounts of the neurotransmitter glutamate, contributing for neuronal excitotoxicity during brain insults. Here, we reveal a signaling pathway controlling glutamate release from human microglia during hypoxia. We show that hypoxia-mediated redox imbalance promotes the activation of endoplasmic reticulum inositol 1,4,5-trisphosphate (InsP) receptors leading to Ca mobilization into the cytosol. Increasing cytosolic Ca signaling in microglia activates the non-receptor protein tyrosine kinase Src at the plasma membrane. Src activation enhances the permeability of microglial gap junctions promoting the release of glutamate during hypoxia. Preventing the hypoxia-triggered redox imbalance, using the dietary antioxidants neochlorogenic acid or vitamin C, inhibits ...

O Sairé marca a identidade desses moradores que compartilham tradições construídas e socializadas através da oralidade e se materializa na ladainha, nos mastros, na procissão, nos símbolos e nas danças. Utilizando a História Oral pretende-se refletir as narrativas desses comunitários num momento de mudanças no Sairé, período de 1996 a 2004, quando se afloram de modo significativo suas percepções sobre cultura, lembrança, tradição e poder
