Lipids in Health and Disease

Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.

Limnology and Aquatic Birds ; Proceedings of the Fourth Conference Working Group on Aquatic Birds of Societas Internationalis Limnologiae (SIL), Sackville, New Brunswick, Canada, August 3-7, 2003

The importance of habitat conservation for the protection of birds has become widely acknowledged and accepted by natural resource managers and the general public. Papers presented in this volume further our understanding of the important role that limnology has in determining habitat suitability for waterbirds. Long-term population monitoring of waterbirds is an important tool in our quest to understand the role waterbirds play in their environment. Continued population declines of many species of aquatic birds indicate the need for additional understanding of how human activities negatively impact water quality and bird populations and what mitigative actions can be taken. The main objective of the Working Group on Aquatic Birds of the International Limnological Society (SIL) is to integrate waterbirds into hydrobiology and treat waterbird studies in a limnological context. To achieve this goal, the Working Group organizes conferences to facilitate communications among limnologists interested in aquatic birds and ornithologists interested in the aquatic habitat. The efforts of the SIL Working Group on aquatic birds has resulted in a new emphasis on the links between aquatic birds and their environment

Light Scattering by Optically Soft Particles: Theory and Applications

Deals with a particular class of approximation methods in the context of light scattering by small particles. This class of approximations has been termed as eikonal or soft particle approximations. The eikonal approximation was studied extensively in the potential scattering and then adopted in optical scattering problems. In this context, the eikonal and other soft particle approximations pertain to scatterers whose relative refractive index compared to surrounding medium is close to unity. The study of these approximations is very important because soft particles occur abundantly in nature. For example, the particles that occur in ocean optics, biomedical optics, atmospheric optics and in many industrial applications can be classified as soft particles. This book was written in recognition of the long-standing and current interest in the field of scattering approximations for soft particles. It should prove to be a useful addition for researchers in the field of light scattering.

Life in Extreme Environments

Investigating life processes under extreme conditions can also bring clues for understanding and predicting ecosystems' responses to global changes. Furthermore, this area of research has a wide application potential in the fields of (bio)technoloty, chemical industry, pharmaceutics, biomedicine or cosmetics.

Life as We Know It

Life As we Know It ["LAKI"] covers several aspects of Life, ranging from the prebiotic level, origin of life, evolution of prokaryotes to eukaryotes and finally to various affairs of human beings. Although it is hard to define Life, one can, however, characterize it and describe its features. Topics treated are categories of bacteria, algae and fungi, conscience, philosophy, theology, aesthetics, appearance of sport and life destiny, life after clinical death, and thoughts of the world to come ("Olam Haba"). The various chapters have been written so that they are accessible to all - from the avid lay reader to the specialist – and make available multidisciplinary sources of information about Life. This volume will interest open minded scholars, students at all levels of general sciences, natural and Life science, researchers of philosophy, theology, history of Life, astrobiology, and those who wish to widen their knowledge about "who are we in the universe".

Life - As a Matter of Fat : The Emerging Science of Lipidomics

Lipids are as important for life as proteins, sugars, and genes. The present book gives a multi-disciplinary perspective on the physics of life and the particular role played by lipids and the lipid-bilayer component of cell membranes. The book is aimed at undergraduate students and young research workers within physics, chemistry, biochemistry, molecular biology, nutrition, as well as pharmaceutical and biomedical sciences. The emphasis is on the physical properties of lipid membranes seen as soft and molecularly structured interfaces. By combining and synthesizing insights obtained from a variety of recent studies, an attempt is made to clarify what membrane structure is and how it can be quantitatively described. Furthermore, it is shown how biological function mediated by membranes is controlled by lipid membrane structure and organization on length scales ranging from the size of the individual molecule, across molecular assemblies of proteins and lipid domains in the range of nanometers, to the size of whole cells. Applications of lipids in nano-technology and biomedicine are also described.

Lessons Learned : Risk Management Issues in Genetic Counseling

The only book devoted exclusively to this specialty, Lessons Learned details the risk management issues involved in genetic counseling practice, and offers solid strategies for minimizing the risk of costly, career-damaging malpractice suits. Schmerler clearly identifies areas of practitioner liability and demonstrates how they may be averted, so counselors can better manage their practice while lowering the risk of legal action. Examples drawn from relevant court cases illustrate typical issues in malpractice, negligence, and breach of contract suits. With this in-depth knowledge, readers can refine their goals toward increased self-protection as well as client care.

Left-right asymmetry in vertebrate development

A host of studies has unravelled the involvement of many genes in the left right patterning pathway. Based on this knowledge the genetic basis of human laterality defects are beginning to be revealed. It is a major challenge now to understand how all these genes control left right development as well as the complex set of interactions established between them.

Lectins

In the intervening years well over 10,000 articles have appeared with lectins as the main subject, and more than twice as many in which they were touched upon, as well as around 20 books. In particular, great strides have been made in several areas of lectin research, about which little was known until the late 1980s. One prominent example is animal lectins, many of which have been discovered only during the last decade and the functions of several of which have been clarified, especially as to their key role in innate immunity.

Landscapes, Genomics and Transgenic Conifers

What is the future of genetically modified (or transgenic) conifer plantations? The content of this edited volume Landscapes, Genomics and Transgenic Conifers addresses this question directly - and indirectly - using language drawn from policy, forest history, genomics, metabolism, pollen dispersal and gene flow, landscape ecology, evolution, economics, technology transfer and regulatory oversight. Although the book takes its title from a Nicholas School Leadership forum held November 17-19, 2004 at Duke University, its de novo contents move past the forum’s deliberations. The result is a trans-disciplinary book composed of 14 chapters written by a total of 31 authors working in North America, South America, Europe and Africa.
