Book excerpt: Nueva edición de la obra de referencia en la disciplina que recoge toda la información necesaria para entender el desarrollo del embrión humano, desde la concepción hasta el momento del nacimiento, con un enfoque claramente molecular. No obstante y a pesar de que se reflejan las últimas investigaciones en regulación génica, señales de transducción, receptores..., la obra no pretende ser un tratado enciclopédico. Cuando se hace referencia al nivel molecular no se hace en profundidad, ya que sólo en una ocasión (cap. 4 y a modo de ejemplo) se reproducen todos los pasos de las vías y las interacciones moleculares implicadas. Cuando se hace referencia a las correlaciones clínicas, el texto se organiza en forma de cuadro de texto y se utiliza siempre el mismo color (morado). Esta nueva edición presenta interesantes fotografías clínicas y dibujos muy claros que ayudan a memorizar de forma bastante fácil los conceptos pertenecientes tanto a un proceso de desarrollo normal como anormal. Como importante novedad, esta edición presenta un enfoque molecular mucho más profundo y facilita la comprensión e interpretación de todos los pasos del desarrollo embrionario a través de imágenes 3D. Al final de cada uno de los capítulos, se incluyen preguntas de autoevaluación para poder contrastar los conocimientos adquiridos. Otro recurso didáctico que presenta la obra es la inclusión al final de cada capítulo de un resumen estructurado en puntos y de preguntas de repaso. Igualmente, a lo largo del texto aparecen las llamadas 'Viñetas clínicas', que plantean un caso cuya respuesta se encuentra al final del libro junto con las de repaso. Se incluye también el recurso online Student Consult que cuenta con animaciones, aparte de todo el contenido extra que ofrece este recurso.

Available in PDF, EPUB and Kindle. Book excerpt: Nueva edicion de una obra muy popular entre los alumnos que revisa los conocimientos mas actualizados sobre embriologia humana y biologia del desarrollo. Recoge con una redaccion muy clara toda la informacion necesaria para entender el desarrollo del embrion humano, desde la concepcion al momento del nacimiento, desde un enfoque esencialmente molecular que explica el porque, ademas del como. Ofrece una vision integral del desarrollo, siguiendo una aproximacion morfologica clasica, y explica el desarrollo normal y el anormal en terminos de procesos celulares y moleculares. Presenta dos puntos fuertes fundamentales. En primer lugar, su marcado caracter didactico, que hace que hasta una disciplina dificil y, aunque muy interesante y necesaria para el alumno, muy ardua resulte asequible y facil de entender, para lo que utiliza, ademas de una redaccion muy clara, numerosas ilustraciones y esquemas a color que facilitan la comprension de los conceptos de desarrollo, recuadros de correlacion clinica, vinetas clinicas, calendarios del desarrollo, tablas sobre moleculas clave y resumenes al final de cada capitulo. En segundo lugar, el extraordinario grado de actualizacion que presenta y la inclusion de todos los mecanismos moleculares importantes que estan en la base del desarrollo. Esta edicion, que ha sido totalmente actualizada y renovada, describe, por ejemplo, algunos conceptos tan importantes como los genes que contienen la homeosecuencia, los miembros de la familia del factor de crecimiento transformante, la familia del factor de crecimiento de los fibroblastos y los genes Pax. Incluye tambien los ultimos avances sobre la asimetria izquierda-derecha, los principales centros de transmision de senales en el embrion inicial, la organizacion transversal del sistema nervioso central, la organizacion molecular del intestino y las bases para el establecimiento precoz del aparato vascular. Como temas nuevos destacan la inclusion de dos moleculas importantes para el desarrollo: la sonic hedgehog y el acido retinoico.

Book excerpt: Anyone wishing to tap the research potential of the hundreds of Drosophila species in addition to D.melanogaster will finally have a single comprehensive resource for identifying, rearing and using this diverse group of insects. This is the only group of higher eukaryotes for which the genomes of 12 species have been sequenced.The fruitfly Drosophila melanogaster continues to be one of the greatest sources of information regarding the principles of heredity that apply to all animals, including humans. In reality, however, over a thousand different species of Drosophila exist, each with the potential to make their own unique contributions to the rapidly changing fields of genetics and evolution. This book, by providing basic information on how to identify and breed these other fruitflies, will allow investigators to take advantage, on a large scale, of the valuable qualities of these other Drosophila species and their newly developed genomic resources to address critical scientific questions. * Provides easy to use keys and illustrations to identify different Drosophila species* A guide to the life history differences of hundreds of species* Worldwide distribution maps of hundreds of species* Complete recipes for different Drosophila diets* Offers an analysis on how to account for species differences in designing and conducting experiments* Presents useful ideas of how to collect the many different Drosophila species in the wild

Available in PDF, EPUB and Kindle. Book excerpt: This book provides complete, comprehensive, and broad subject-based reviews for students, teachers, researchers, policymakers, conservationists, and NGOs interested in the biodiversity and conservation of woody plants. Forests cover approximately 31 percent of the world’s total landmass; 93 percent is natural forest and only 7 percent consists of planted trees. Forest decline is progressing at an alarming rate worldwide. In addition to human activities (logging, deforestation, and exploiting forest lands for agriculture and industrial use), a number of other factors – including pests and diseases, drought, soil acidity, radiation, and ozone – are cumulatively contributing to global forest decline. The present situation forces us to focus on forest conservation strategies for the present and future. Gene conservation and maintaining genetic diversity in forest ecosystems are crucial to the preservation of forest genetic resources. This calls for integrated action to implement both the in situ (on site) preservation of forest stands and ex situ (distant from the original site) strategies for the conservation of woody plants’ genetic resources. Selected priority areas include: 1) assessing patterns of genetic diversity and threats, 2) understanding the biological processes regulating genetic diversity, 3) assessing the impact of human activities and climate change on genetic diversity, and 5) finding methods for prioritizing species and populations for the conservation of forest trees genetic resources. All chapters were written by leading scientists in their respective fields, which include: woody plant diversity, ecology and evolution; assessment of genetic diversity in forest tree populations; conservation planning under climate change; and in situ and ex situ strategies, including biotechnological approaches, for the conservation of woody plants genetic resources.

Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Hair Growth is based on a conference on The Biology of Hair Growth, sponsored by the British Society for Research on Ageing, held at the Royal College of Surgeons, in London, 7-9 August 1957. The papers presented at this conference, and a few others, have been gathered in this book to serve as a source reference for all those interested in research on hair and hair growth. The application of modern methods in histology, cytology, histochemistry, physiology, electron microscopy, the use of radioactive isotopes, and modern biochemical techniques have given greater insight into the phenomena of growth and differentiation of hair follicles than ever before. The book opens with a chapter on the embryology of hair. Separate chapters follow on the anatomy and histochemistry of the hair follicle; the electron microscopy of keratinized tissues; the chemistry of keratinization; the mitotic activity of the follicle; and the the vascularity and patterns of growth of hair follicles. Subsequent chapters deal with behavior of pigment cells and epithelial cells in the hair follicle; the nature of hair pigment; the effects of nutrition on hair growth; and effects of chemical agents, ionizing radiation, and particular illnesses on hair roots.
