Cell Culture

  • 1st Edition
  • Volume 2
  • P. Michael Conn
  • English
The ability to assess the response of neural cells is an important goal of research in the neurosciences. The means to measure responses in a chemically defined medium is a positive feature of the use of cell culture and is the major reason its use is so important in this discipline.Techniques for the purification of cells for culture, for large-scale isolation, for assessing differentiated function, and for tracing lineage are included. Many of the methods can easily be adapted to other systems.

Photosynthetic Reaction Center, Two-Volume Set

  • 1st Edition
  • J. R. Norris + 1 more
  • English
The availability of the photosynthetic reaction center's structure at an atomic resolution of less than three angstroms has revolutionized research. This protein is the first integral membrane protein whose structure has been determined with such precision. Each volume of The Photosynthetic Reaction Center contains original research, methods, and reviews. Together, these volumes cover our current understanding of The availability of the photosynthetic reaction center's structure at an atomic resolution of less than three angstroms has revolutionized research. This protein is the first integral membrane protein whose structure has been determined with such precision. Each volume of the Photosynthetic Reaction Center contains original research, methods, and reviews. Together, these volumes cover our current understanding of how photosynthesis converts light energy into stored chemical energy.Volume I:Volume I describes the chemistry and biochemistry of photosynthesis, including green plant photosynthesis; it is devoted to the overall features and implications of the bacterial reaction center for green plant research. It features a new description of the structure of the reaction center, followed by coverage of the antenna and light functions. Volume I also details new manipulations of the reaction center including chemical and genetic modifications. It describes how the reaction center provides reducing power via electron transfer chemistry coupled to proton uptake and release; coupling of electron transport between the oxidized reaction center and the aqueous periplasm; and the general operation of membrane-bound proteins. Additionally, this volume contains five chapters detailing facets of green plant photosynthesis important for future research.Volume II:Volume II details the electron transfer process; it is oriented to the physical aspects of photosynthesis. It thus primarily discusses bacterial photosynthesis and model compounds. Volume II features the very complex and rapidly evolving issues associated with the theory of electron transfer in the bacterial reaction center, and explores picosecond and femtosecond spectroscopy. This volume also covers holeburning spectroscopy; primary events of bacterial photosynthesis with emphasis on the application of large, external electric fields designed to manipulate and probe mechanisms of the initial chemistry; the role of accessory carotenoid pigments; the techniques of infrared spectroscopy and magnetic resonance as applied to photosynthesis; and the interplay between natural and artificial photosynthesis.

Neurofibromatosis Type I

  • 1st Edition
  • M. Upadhyaya + 1 more
  • English
Neurofibromatosis type 1 (NF1) is one of the most common dominantly inherited neurogenetic disorders. Affecting 1 in 4000 individuals worldwide. Symptoms include facial and body disfigurement, mental retardation and abnormalities of the cardiovascular, renal and endocrine systems.This book is written for a broad readership ranging from students to professionals. It provides the reader with a basic overview of the disease before discussing the most recent research and therapeutic developments in detail. It is essential reading for medical geneticists, molecular biologists, dermatologists, oncologists, neurologists, genetic counsellors, general practitioners and research students.The volume attempts to cover clinical aspects of the disease; gene structure, expression and mutation; structural and functional aspects of the encoded protein, neurofibromin; the role of the NF1gene as a tumour suppressor, the emerging genotype-phenotype relationship for NF1, animal models of the disease and future prospects for disease treatment and prevention.

Encyclopedia of Birds

  • 2nd Edition
  • Joseph Forshaw
  • English
Humans have long been captivated by birds; they have been featured prominently in art, mythology, and folklore as symbols of wisdom and truth, strength and power, beauty and death. Humans are perhaps most in awe of birds' ability to fly. Flight has enabled them to colonize virtually every habitat. Birds also display a great diversity of color and form. They are united by the possession of feathers--the defining characteristic of birds.Many species are threatened by habitat destruction and extinction, and their survival is dependent on our appreciation and understanding and the preservation of their habitats. This beautifully illustrated book, with more than 200 magnificent color photographs and 150 original paintings, maps, and diagrams, presents an up-to-date and comprehensive survey of the natural history of birds. The authoritative text has been written by the world's leading ornithologists and includes the most recent scientific findings in a stimulating presentation.

The Black Eagle

  • 1st Edition
  • Bozzano G Luisa
  • English
This long-awaited and important volume comprises the most detailed, comprehensive, and prolonged single study of an eagle species ever undertaken. Thousands of hours of observation in the field during a 21-year period and more than 12,000 written records by a team of voluntary birdwatchers, have gone into the investigation of the behavior and breeding of some 60 pairs of Black Eagles in their natural environment-the Matobo Hills of Zimbabwe.Exquisite paintings by renowned bird artist Graeme Arnott, and a series of behavioral sketches by eagle-student Robert Davies, add an extra dimension to an appreciation of the Black Eagle. Their inclusion, together with a selection of color photographs,both from the authors unique and extensive collection and by photographers of note, makes this a volume to be treasured by collectors of Africana as well as by all birds of prey enthusiasts.

Encyclopedia of Mammals

  • 2nd Edition
  • Edwin Gould + 1 more
  • English
Mammals are our closest relatives in the animal kingdom; most are beautiful, and many are highly intelligent and have intricate social systems. They are found in all kinds of habitats; they may have fur, scales, or spines; they move by hopping, swimming, running, or flying. What all mammals share, apart from certain anatomical similarities, is the unique ability to nourish their young with milk from mammary glands.Many species of mammals are severely threatened by habitat destruction and encroachment, and some face extinction within the near future. A better understanding and appreciation of mammals by humans is essential to their survival.This lavishly illustrated book presents in a lively and visually stimulating way the most recent findings of scientific research. Authoritative text written by the world's leading mammalogists is enhanced by over 200 superb photographs and over 100 original paintings, diagrams, and maps to give an up-to-date overview of our knowledge of the fascinating lives of animals.
