RESUMEN
Though introduced recently, complex networks research has grown steadily because of its potential to represent, characterize and model a wide range of intricate natural systems and phenomena. Because of the intrinsic complexity and systemic organization of life, complex networks provide a specially promising framework for systems biology investigation. The current article is an up-to-date review of the major developments related to the application of complex networks in biology, with special attention focused on the more recent literature. The main concepts and models of complex networks are presented and illustrated in an accessible fashion. Three main types of networks are covered: transcriptional regulatory networks, protein-protein interaction networks and metabolic networks. The key role of complex networks for systems biology is extensively illustrated by several of the papers reviewed.
RESUMEN
Este trabalho apresenta os resultados referentes à aplicação de um novo descritor multi-escala de formas, chamado Energia de Dobramento (ED), para problemas de neuromorfometria. O descritor é introduzido, e resultados demonstrando: (1) a capacidade de discriminação da complexidade da forma das células neurais e (2) invariância à transformações geométricas, são apresentados.
