Neuroprotection is conceived as one of the potential tool to prevent or slow neuronal death and hence a therapeutic hope to treat neurodegenerative diseases, like Parkinson’s and Alzheimer’s diseases. Increase of oxidative stress, mitochondrial dysfunction, excitotoxicity, inflammatory changes, iron accumulation, and protein aggregation have been identified(More)
The mating system of seven sympatric taxa of Chamaecrista occurring in the Chapada Diamantina Mountains, northeastern Brazil, was studied to determine the occurrence of self-incompatibility and interspecific genetic isolation mechanisms within the group. Self- and cross-pollination experiments and inter-taxon bidirectional crosses were performed. All of the(More)
Introduction Sugarcane biomass can be exploited in order to increase the production of bioethanol, produced in Brazil from sugarcane juice. The second generation process, whichever technology is selected to be implemented, must be integrated to the first generation production process, in order to reduce costs and increase biofuel competitiveness.(More)
