La gripe es una enfermedad producida por un grupo de virus que no conocen otras fronteras que la susceptibilidad de sus huéspedes. Este hecho hace que las contribuciones científicas en el mundo de la gripe se hagan desde muchas aproximaciones de distintas especialidades academicas.La gripe y los virus de la gripe son capaces de integrar a veterinarios y biologos con medicos, a virologos y a microbiologos con sanitarios, y a estos con enfermeras y gestores de la salud. Por esa razon nace este libro dedicado a los virus de la gripe, pandemias, epidemias y vacunas. En el se pretende aportar y compilar de una forma didactica el conocimiento actual en distintas parcelas de la biologia, la estructura, la evolucion, el tratamiento, las vacunas, etc.Todos los autores del libro tienen nacionalidad española, esten trabajando o no en España. Este hecho obedece a dos factores. En nuestro pais existe sobrada experiencia y talento en muchos de los temas relacionados con la virologia, la epidemiologia y otros aspectos relacionados con la ecologia y distribucion del virus de la gripe en la naturaleza. Segundo, no existe hasta ahora ningun libro de estas caracteristicas escrito en lengua española, y esto puede servir para que esta obra tenga una mayor difusion en otros paises de habla hispana.En muchas ocasiones, las barreras linguisticas contribuyen a hacer menos entendibles aspectos realmente complejos de la biologia, la evolucion y la terapia de los virus de la gripe, por citar solo algunos de ellos se redactan en este libro de forma didactica y comprensible, todo ello debe ayudar al lector a obtener el maximo partido de su lectura.Esperamos que una obra de estas caracteristicas goce de la aceptacion academica del publico y los lectores a los que va dirigido. Esta es una obra pensada para formar e informar no solo a profesionales que ya tienen una trayectoria academica definida, como veterinarios, biologos, medicos, quimicos, con relacion o sin ella con el virus, sino tambien para estudiantes o personas de toda indole y formacion, que quieran tener un conocimiento cientifico veraz, de la mano de especialistas, sobre la gripe y los virus de la gripe.

El herpes zóster (HZ) es una enfermedad que acompaña desde antiguo a la humanidad, si bien es cierto que los clásicos no diferenciaban entre herpes zóster y otras enfermedades eruptivas de la piel en sus escritos. No fue hasta finales del s. XVIII cuando se establecio una forma de diferenciar el herpes zoster de la viruela, y a finales del siglo XIX se distinguio de la erisipela.El HZ esta causado por el virus herpes tipo 3 o virus varicela-zoster (VVZ), uno de los ocho virus conocidos de la familia Herpesviridae. Tiene distribucion mundial y la susceptibilidad es universal. El unico reservorio es el ser humano, y la transmision se produce de persona a persona por contacto directo a traves de la piel, por via respiratoria o por via conjuntiva.Se produce por la reactivacion endogena del VVZ. Es decir, para desarrollar un HZ, es preciso haber sufrido una primoinfeccion, generalmente en la infancia, que aparecera en forma de varicela (clinica o subclinica). Una vez superada la primoinfeccion, el VVZ queda acantonado en los ganglios sensitivos hasta su eventual reactivacion.

Superb... A testament to just how beautiful and wonderful life on Earth isTimes Literary SupplementFascinatingGuardianBrilliant Daily MailFrom scorching deserts to frozen seabeds, from the highest peaks of the Himalaya to the hadal depths of the oceans, there are habitats on this Earth that appear inimical to life - yet in which it flourishes nevertheless.

Este libro integra distintas aproximaciones sobre la química de las especies utilizadas como colorantes tradicionales en Nabusímake, Sierra Nevada de Santa Marta, con el fin de mostrar, interdisciplinarmente, diferentes facetas del estudio y empleo de los colorantes. Las especies fueron identificadas y se establecio la composicion en metabolitos responsables de la propiedad tintorea, en dos de estas especies se determino por primera vez su fitoquimica. Se reprodujeron y sistematizaron tecnicas de teñido en fibras de fique y algodon con la participacion de la comunidad ika de Nabusimake, en particular con la del grupo de mujeres Aty kinchukwa. A partir de la informacion sobre los colorantes determinados en textiles arqueologicos y el estudio de colecciones de textiles etnograficos del norte de Colombia, se obtuvo evidencia sobre la continuidad en el empleo de las fuentes de colorantes en esta region. La obra resalta la importancia cultural del teñido para los indigenas ika y la necesidad de continuar con la implementacion de proyectos en el territorio relacionados con el conocimiento y manejo de los colorantes tradicionales.
