Book Description
International Review of Cytology presents current advances and comprehensive reviews in cell biology--both plant and animal. Authored by some of the foremost scientists in the field, each volume provides up-to-date information and directions for future research. This volume looks at water movements from a wide range of levels. It examines how water interacts with the major components of the cell, including proteins and lipids. It discusses how water moves across cell membranes by diffusion, how it is chanelled across these membranes or, in certain cases, pumped across, and how water movements are controlled. This book demonstrates how water and ion movements are closely linked in order to provide a better understanding of their behavior. *Essential Physical chemistry of water at biological interfaces *Up-to-date reviews of water behavior in cells *Water in integrated systems *Current information on water channels across membranes

Book Description
The main purpose of this book is to provide in-depth presentation of physical techniques for measuring water transport and their applications to a variety of biological membranes, from model membrane systems to cell membranes, and then from isolated cells to multicellular barrier systems, such as epithelia or even whole organisms. This survey of water transport in such a broad range of membrane systems will hopefully contribute to understanding of the structure-function relationships and molecular mechanisms of water permeation. Moreover, the description of various techniques, together with a review of literature will enable the readers to assess whether a technique would be useful in helping to solve his or her particular problem of research and will also expand their competence in these techniques. The book consists of two volumes.

Book Description
Aquaporins are channel proteins that facilitate the diffusion of water and small uncharged solutes across cellular membranes. Plant aquaporins form a large family of highly divergent proteins that are involved in many different physiological processes. This book will summarize the recent advances regarding plant aquaporins, their phylogeny, structure, substrate specificity, mechanisms of regulation and roles in various important physiological processes related to the control of water flow and small solute distribution at the cell, tissue and plant level in an ever-changing environment.

Book Description
There is a general agreement that investigating the permeability characterises of biological membranes not only has intrinsic value but could also contribute to our understanding of the function and structure of membranes. The main purpose of this book is to provide in-depth presentations of physical techniques for measuring water transport and their applications to a variety of biological membranes, from model membrane systems to cell membranes, and then from isolated cells to multicellular barrier systems, such as epithelia or even whole organisms. This survey of water transport in such a broad range of membrane systems will hopefully contribute to understanding of the structure-function relationships and molecular mechanisms of water permeation.

Book Description
Water Relations in Membrane Transport in Plants and Animals contains the presentations in a symposium dealing with Water Relations in Membranes in Plants and Animals, during the 27th Annual Fall Meeting of the American Physiological Society held at The University of Pennsylvania, 17-19 August 1976. The purpose of the symposium was to explore the common modes of water regulation in plants and animals. In these proceedings, the mechanisms employed to restrict water flow across plant and metazoan animal cells are described. Putative differences in mechanisms of water regulation retained by plant versus animal cells become inconsequential in the light of the numerous similarities: dependence upon bioelectric potentials maintained across cell membranes, energy dependence of uphill water movement, and solute coupling during water transport. The presentations can be organized into four. The first takes up specific mechanisms of water transport in plants. The second and third parts deal with specific mechanisms in invertebrates and vertebrates, respectively. The fourth part covers generalized mechanisms common to plants and animals.

Book Description
Superlubricity is defined as a sliding regime in which friction or resistance to sliding vanishes. It has been shown that energy can be conserved by further reducing/removing friction in moving mechanical systems and this book includes contributions from world-renowned scientists who address some of the most fundamental research issues in overcoming friction. Superlubricity reviews the latest methods and materials in this area of research that are aimed at removing friction in nano-to-micro scale machines and large scale engineering components. Insight is also given into the atomic-scale origins of friction in general and superlubricity while other chapters focus on experimental and practical aspects or impacts of superlubricity that will be very useful for broader industrial community. * Reviews the latest fundamental research in superlubricity today * Presents 'state-of-the-art' methods, materials, and experimental techniques * Latest developments in tribomaterials, coatings, and lubricants providing superlubricity

Book Description
The interface between a living cell and the surrounding world plays a critical role in numerous complex biological processes. Sperm/egg fusion, virus/cell fusion, exocytosis, endocytosis, and ion permeation are a few examples of processes involving membranes. In recent years, powerful tools such as X-ray crystal lography, electron microscopy, nuclear magnetic resonance, and infra-red and Raman spectroscopy have been developed to characterize the structure and dy namics of biomembranes. Despite this progress, many of the factors responsible for the function of biomembranes are still not well understood. The membrane is a very complicated supramolecular liquid-crystalline structure that is largely composed of lipids, forming a bilayer, to which proteins and other biomolecules are anchored. Often, the lipid bilayer environment is pictured as a hydropho bic structureless slab providing a thermodynamic driving force to partition the amino acids of a membrane protein according to their solubility. However, much of the molecular complexity of the phospholipid bilayer environment is ignored in such a simplified view. It is likely that the atomic details of the polar head group region and the transition from the bulk water to the hydrophobic core of the membrane are important. An understanding of the factors responsible for the function of biomembranes thus requires a better characterization at the molec ular level of how proteins interact with lipid molecules, of how lipids affect protein structure and of how lipid molecules might regulate protein function.
