Fulcrum and Torsion of the Helical Myocardium
In this new book, Trainini and his team attempt a step forward and make a series of proposals that come to complete cardiac anatomy, physiology and mechanics. Reading this new investigation is a pleasure that demands continuous attention, so that our "neuronal boxes" do not rebel against the effort it means to sometimes destroy what we have firmly installed in them. The text should be read slowly, as it was never easy to tread in swamp-limited grounds and, as in the ascent to the summit of a difficult mountain, stop now and then to take a breath and enjoy the view as we get near the peak, where we will see the final landscape of the new vision. Then we will be conscious that the effort was worthwhile.
Myocardial torsion
Myocardial Torsion is a book different from others, simply because this book is unique, unusual, and I dare say with admiration, it is a curious book, partly magical, full of personality, for initiatory readers, revealing, provocative, challenging. The book has the infrequent peculiarity of being based, to a great extent, on original personal and multidisciplinary investigations, granting it an important extra value. The authors define their purpose since the firsts pages of the book: to provide solidity, validity and even more to Torrent Guasp's concepts. This is certainly a different book in its structure, content and elaboration. It is a text that the reader may admire or criticize, that may create skepticism or surprise at the new data it propose, but wich undoudtedly will leavenobody indifferent, and that is something few books can achieve.
Savage and civilized
On a sunny January morning in 1833, through one of the Southern Channels of Tierra del Fuego, a British vessel sails alongside a smaller boat. The natives of the area, through screams and smoke, quickly communicate with each other the novelty, and dozens of canoes with hundreds of natives emerge to observe the peculiar event. Curious and friendly for the most part, somewhat aggressive at times, they observe the smallest boat approaching the shore with three Fuegians (two men and one woman) returning to their homeland after almost a year in London. To the surprise of their compatriots, who receive them almost naked, these three Fuegians dressed in European clothes, with short hair, speak Engl...
En busca del fulcro cardíaco
La pregunta inevitable de la investigación surgió porque los segmentos musculares que conforman las cavidades ventriculares debían contar con un punto de apoyo para poder torsionarse, al igual que un músculo esquelético lo hace en una inserción firme, ¿había entonces un punto de apoyo en el corazón? Si existía, ¿cómo se insertaba el miocardio en dicha estructura? ¿Es posible que el corazón (un músculo continuo plegado en helicoide) se considere desde siempre péndulo en el mediastino, vertical, sin ataduras, cuando todo músculo se halla inserto en algún sitio para cumplir su papel con la fuerza necesaria? Esta situación anatómica sin duda obliga al corazón, del tamaño equivalente a un puño humano, a tener un punto de apoyo para poder cumplir con una función de bomba que impulsa un volumen de 4 a 6 litros/minuto a una velocidad de 200 cm/s contra la ley de gravedad; tener un consumo de solo 10 vatios, y que le permita trabajar en continuidad durante 80 años sin mantenimiento en una tarea ni siquiera alcanzada por máquinas construidas por el hombre. Era evidente que necesitaba de un soporte y esta era la pregunta que esperaba ser indagada.
Fisiología de la succión cardiaca
Todo conocimiento es una secuencia de lo previo pero no está exento de ser considerado una tempestad. Sucede cuando los cimientos que se intentan reformar están muy anclados en el tiempo y en la praxis. La historia de la circulación de la sangre evolucionó a través de tres saltos fundamentales. El inicial, obrade Claudio Galeno (siglo II d.C.) perduró hasta 1628, cuando William Harvey publica Exercitatio anatomica motu cordis et sanguinis in animalibus, sentandola moderna fisiología ciculatoria. A pesar de su principio de razón suficienteno le fue sencillo alconocimiento de Harvey destronar los catorce siglos de la hegemonía impuesta por el sistema circulatorio de Galeno. La sangre ...
The Happiness Advantage
Most people want to be successful in life. And of course, everyone wants to be happy. When it comes to the pursuit of success and happiness, most people assume the same formula: if you work hard, you will become successful, and once you become successful, then you'll be happy. The only problem is that a decade of cutting-edge research in the field of positive psychology has proven that this formula is backwards. Success does not beget happiness. Based on the largest study ever conducted on happiness and human potential (a survey conducted by the author of more than 1,600 students), Harvard lecturer Shawn Achor shares seven core principles of positive psychology that each one of us can use to improve our performance, grow our careers, and gain a competitive edge at work. He reveals how happiness actually fuels success and performance, not the other way around. Why? Because when we are happier and more positive we are more engaged, creative, resilient to stress, and productive. The Happiness Advantage will appeal to anyone who wants practical advice on how to become happier and also more successful.
