  • This volume is the first book-length survey of caveolae and lipid rafts. Interest has developed rapidly in the role of these surface microdomains in such diverse fields as transmembrane signaling, cell locomotion, vascular relaxation, senescence, and the uptake and exit from cells of viruses and bacteria. Individual chapters in this volume cover areas as diverse as the forces that induce and maintain membrane invaginations, and the clinical relevance of multiprotein complexes at the cell surface, defects in which are associated with cancer, and Alzheimer’s and prion-dependent diseases....

  • The concept of 'biotech' or 'biotechnology' encompasses a wide range of procedures (and history) for modifying living organisms according to human purposes — going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies.

  • Biotechnology (sometimes shortened to "biotech") is generally accepted as the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use" (UN Convention on Biological Diversity)[1] . For thousands of years, humankind has used biotechnology in agriculture, food production and medicine.[2] The term itself is largely believed to have been coined in 1919 by Hungarian engineer Karl Ereky.

  • The extracellular matrix (ECM) represents a complex organization of macromolecules that surrounds the cell and comprises the substratum onto which the cell may be attached. The properties and functions of the ECM depend ultimately on its structure, molecular components, architecture, and dynamic modulation. Because the critical role of ECM involved in cell biology and physiology has long been recognized, the structure and biology of the ECM have been extensively studied (Yurchenco and Birk 1994 ; Ayad et al. 1998 ; Robert 2001 ) .

  • Using the broadest possible definition, a lipid (Greek lipos = fat ) may be defined as a compound of low or intermediate molecular weight (5000), a substantial proportion of which is made up of hydrocarbons. Included are diverse compounds such as fatty acids; soaps; detergents; steroids; mono-, di-, and triacylglycerols; and more complex compounds such as phospholipids, sphingolipids, glycolipids, and lipopolysaccharides.

  • Almost since their inception, the natural sciences, those fields that use the scientific method to study nature, have been divided into two branches: the biological sciences and the physical sciences. In part, this division can be viewed as a convenient social contrivance. However, over time it has also served more functional purposes. Physical scientists, when seeking the fundamental laws, have found it necessary to focus on the simplest of systems—elementary particles, atoms, and molecules—items clearly not alive.

  • From microorganisms to whales, from single cells to complex organisms, from plants to animals to fungi, from body plans to behavior, the diversity of life is amazing. Living organisms have a profound impact on our physical world of ocean, landscape, and climate; around us is a multitude of diverse ecosystems that provide a livable environment and many valuable resources. The study of life—biology—is a multifaceted endeavor that uses observation, exploration, and experiments to gather information and test hypotheses about topics ranging from climate change to stem cells.
