  • A global research community of scientists is teasing out the biochemical mechanisms that regulate normal cellular physiology in a variety of organisms. Much of current research aims to understand the network of molecular reactions that regulate cellular homeostasis, and to learn what allows cells to sense stress and activate appropriate biochemical responses.

  • The fact that there is a reciprocal relation between mental states and bodily conditions, acting both for good and ill, is nothing new in human experience. Even among the most crude and unobserving, traditions and incidents have given witness to this knowledge. For centuries stories of the hair turning white during the night on account of fright or sorrow, the cause and cure of diseases through emotional disturbances, and death, usually directly by apoplexy, caused by anger, grief, or joy, have been current and generally accepted.

  • WATER PLAYS A CRUCIAL ROLE in the life of the plant. For every gram of organic matter made by the plant, approximately 500 g of water is absorbed by the roots, transported through the plant body and lost to the atmosphere. Even slight imbalances in this flow of water can cause water deficits and severe malfunctioning of many cellular processes. Thus, every plant must delicately balance its uptake and loss of water. This balancing is a serious challenge for land plants. To carry on photosynthesis, they need to draw carbon dioxide from the atmosphere, but doing so exposes them to...

  • 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 ) .

  • Within the last decade the interest in lipases has increased dramatically, and no doubt, this interest will be maintained in the future. Novel and powerful tools of molecular biology, crystallography, NMR technology and molecular modeling will continue to reveal new amino acid sequences and three-dimensional structures of lipases. In addition, transgenic and knockout animal models as well as the use of specific inhibitors will add knowledge about their mode of interaction with lipid substrates, cleavage mechanism and physiological roles in humans....

  • The basic precepts underlying previous editions of Clinical Drug Therapy continue to guide the writing of this seventh edition. The overall purpose is to promote safe, effective, and rational drug therapy by: • Providing information that accurately reflects current practices in drug therapy. • Facilitating the acquisition, comprehension, and application of knowledge related to drug therapy. Application requires knowledge about the drug and the client receiving it.

  • PHOTOSYNTHESIS PROVIDES the organic building blocks that plants (and nearly all other life) depend on. Respiration, with its associated carbon metabolism, releases the energy stored in carbon compounds in a controlled manner for cellular use. At the same time it generates many carbon precursors for biosynthesis. In the first part of this chapter we will review respiration in its metabolic context, emphasizing the interconnections and the special features that are peculiar to plants.

  • THE CYTOKININS WERE DISCOVERED in the search for factors that stimulate plant cells to divide (i.e., undergo cytokinesis). Since their discovery, cytokinins have been shown to have effects on many other physiological and developmental processes, including leaf senescence, nutrient mobilization, apical dominance, the formation and activity of shoot apical meristems, floral development, the breaking of bud dormancy, and seed germination.

  • Alternative oxidase (AOX) is a ubiquitous respiratory enzyme found in plants, fungi, protists and some bacterial species. One of the major ques-tions about this enzyme is related to its metabolic role(s) in cellular physi-ology, due to its capacity to bypass the proton-pumping cytochrome pathway, and as a consequence it has great energy-wasting potential.

  • Metabolomics is the scientific study of chemical processes involving metabolites. Specifically, metabolomics is the "systematic study of the unique chemical fingerprints that specific cellular processes leave behind", the study of their small-molecule metabolite profiles.[1] The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, which are the end products of cellular processes.

  • If one asks what neuroscience is, the answer can be found in this book. Neuroscience embraces not only anatomical and physiological studies but also cell biology, computer science, and biochemistry. Equally important for neuroscientific research are other disciplines, such as psychology, psychiatry, neurology and additional recent ones, such as neuroeconomics and social neuroscience. This book comprises chapters on diverse topics in neuroscience ranging from cellular, computational, cognitive, and clinical neuroscience.

  • Nutritional Biochemistry takes a scientific approach to nutrition. It covers not just "whats"--nutritional requirements--but why they are required for human health, by describing their function at the cellular and molecular level. Each case study either leads to a subsequent discovery or enables an understanding of the physiological mechanisms of action of various nutrition-related processes. The text is "picture-oriented" and the commentary is directed towards explaining graphs, figures, and tables. ...
