Найти книгу: "Centros y cuerpos sutiles"

Desde hace miles de anos los hombres se estan ejercitando para multiplicar y amplificar sus sensaciones y percepciones mediante el uso de los cinco sentidos, y este juego sobre el teclado de los cinco sentidos es lo que llaman cultura y civilizacion. Pues bien, eso es algo pobre. A pesar del grado de refinamiento que puedan alcanzar, los cinco sentidos siempre estaran limitados, porque solo pertenecen al plano fisico y no exploraran otra cosa que el plano fisico. Mientras los seres humanos no comprendan que hay otros campos a explorar, ver, tocar, respirar, no podran experimentar nuevas sensaciones, mas amplias, mas ricas, mas sutiles. Cada organo esta especializado: cumple una determinada funcion y solo produce sensaciones de acuerdo a su naturaleza. Para experimentar sensaciones nuevas, hay que dirigirse a otros organos, a otros centros sutiles que tambien poseemos.

Discovered over a century ago, the centrosome is the major microtubule organizing center of the animal cell. It is a tiny organelle of surprising structural complexity. Over the last few years our understanding of the structure and composition of centrosomes has greatly advanced, and the demonstration of frequent centrosome anomalies in most common human tumors has sparked additional interest in the role of this organelle in a broader scientific community. The centrosome controls the number and distribution of microtubules – a major element of the cell cytoskeleton – and hence influences many important cellular functions and properties. These include cell shape, polarity, and motility, as well as the intracellular transport and positioning of various organelles. Of particular interest, centrosome function is critical for chromosome segregation and cell division. This book is meant to summarize our current knowledge of the structure, function and evolution of microtubule organizing centers, primarily centrosomes. Emphasis is on the role of these organelles in development and disease (particularly cancer).
