Book Synopsis La piel de la vida by : Barco Ríos, John

Download or read book La piel de la vida written by Barco Ríos, John. This book was released on 2024-07-09. Available in PDF, EPUB and Kindle. Book excerpt: Es sorprendente que una estructura tan diminuta, de dimensiones ultramicroscópicas y con una organización estructural aparentemente sencilla, pueda desempeñar funciones tan decisivas e importantes para la vida de las células. Me refiero a la membrana citoplasmática; esa delicada y finísima piel que recubre y aísla la célula de su entorno natural y le confiere la individualidad necesaria para funcionar, en muchos casos, como un organismo independiente, capaz de alimentarse a través de ella, de comunicarse con las demás células por intermedio de ella y de desencadenar multitud de mecanismos fisiológicos por virtud de ella. A pesar de haber transcurrido poco más de un siglo desde que el botánico inglés Ernest Overton determinara, por métodos indirectos, que las membranas estaban conformadas por una mezcla de lecitinas y colesterol, a pesar de los avances en microscopía y de los novedosos instrumentos y técnicas de laboratorio, aún no ha sido posible develar por completo o, si se quiere, corroborar de una buena vez la organización estructural que presentan realmente las membranas biológicas y, de paso, dar explicación a ciertos mecanismos fisiológicos que todavía no se comprenden bien. He aquí el enorme atractivo que tiene esta diminuta estructura para los biólogos moleculares. He aquí la desbordante fascinación que sigue despertando en mí desde aquellos primeros años como estudiante universitario, la misma que he tratado de despertar siempre en mis estudiantes y que ahora espero despertar en aquellos lectores que deseen incursionar y aprender algo de esta maravillosa piel de la vida.

Book Synopsis Human Physiology by : Gillian Pocock

Download or read book Human Physiology written by Gillian Pocock. This book was released on 2004. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of Human Physiology - an Oxford Core Text continues to meet the needs of preclinical medical students and is also of value to those following undergraduate courses in physiology and other health-related disciplines. It adopts a student-friendly style with an emphasis on clarity, explanation and understanding complemented by full-color illustrations. The book has a hierarchical organization, beginning with aspects of cell and tissue function before proceeding to a consideration of the communication systems of the body including the endocrine and nervous systems. The heart of the text concerns the physiology of the main body systems. The new edition has been significantly revised to include an expanded problem section at the end of each chapter with more quantitative examples and some clinical problems where appropriate. Each chapter has been updated and new material includes a section on the physiology of itch; more detailed treatment of colour vision, deafness and vestibular blindness; increased emphasis on neurology disorders; discussion of the physiology of respiratory failure and pulmonary embolism; a discussion of malabsorption disorders; extensive revision to cover the wider aspects of material physiology not just lactation, and extended treatment of fever. The Clinical Physiology chapter is now broken into several short chapters and includes a discussion of cardiovascular pathophysiology and organ failure.
