The distinction between mechanisms that generate biological variation and mechanisms that modify it has been important in contemporary Biology, especially since the establishment of the Evolutionary Synthesis (ES) in the ...

Most neurodegenerative diseases involve the accumulation of misfolded proteins in the nervous system. Impairment of protein degradation pathways such as autophagy is emerging as a consistent and transversal pathological ...

The kinetic mechanisms of Escherichia coli phosphofructokinase-2 (Pfk-2) and of the mutant enzyme Pfk-2* were investigated. Initial velocity studies showed that both enzymes have a sequential kinetic mechanism, indicating ...

Under the assumption that neurogenesis is a fully random process then some laws such as the ones belonging to quantum mechanics might be applied. In this paper, it is assumed that along the process of creation of new ...

The reproductive biology, reward production and pollination mechanism of Trichocentrum pumilum were studied in a gallery forest in the interior of the State of Sao Paulo, southeast Brazil. The floral visitors and pollination ...

Dimensional analysis and the theory of biological similarities were applied to the mammalian respiratory system. Through dimensional and solution matrices a set of 9 Pi-numbers of Buckingham was obtained. Products of ...
