      Natural Hosts of SIV: Implications in AIDS thoroughly reviews the possible mechanisms by which African nonhuman primate natural hosts of lentiviruses remain essentially disease-free while other hosts exhibit disease and death. The book ultimately indicates directions for further research and potential translations of this compelling phenomenon into novel approaches to treat and prevent HIV. When Asian non-human primate non-natural hosts are experimentally infected with viruses isolated from African species, disease and death normally results. Meanwhile, these African nonhuman primate natural hosts maintain similar levels of plasma and cellular viremia and exhibit compellingly different, essentially disease-free, states. This work attempts to answer the question of how the natural host remains disease resistant.

      Feeding Everyone No Matter What presents a scientific approach to the practicalities of planning for long-term interruption to food production. The primary historic solution developed over the last several decades is increased food storage. However, storing up enough food to feed everyone would take a significant amount of time and would increase the price of food, killing additional people due to inadequate global access to affordable food. Humanity is far from doomed, however, in these situations - there are solutions. This book provides an order of magnitude technical analysis comparing caloric requirements of all humans for five years with conversion of existing vegetation and fossil fuels to edible food. It presents mechanisms for global-scale conversion including: natural gas-digesting bacteria, extracting food from leaves, and conversion of fiber by enzymes, mushroom or bacteria growth, or a two-step process involving partial decomposition of fiber by fungi and/or bacteria and feeding them to animals such as beetles, ruminants (cows, deer, etc), rats and chickens. It includes an analysis to determine the ramp rates for each option and the results show that careful planning and global cooperation could ensure the bulk of humanity and biodiversity could be maintained in even in the most extreme circumstances.

      Cis-Trans Isomeric Carotenoids, Vitamins A, and Arylpolyenes focuses on the reactions, characteristics, and properties of cis-trans isomeric carotenoids, vitamins A, and arylpolyenes. The publication first takes a look at carotenoids, number, types, and properties of cis carotenoids, and cis-trans isomerism and UV spectra. Discussions focus on simple theoretical interpretation of spectral phenomena, spectra at extremely low temperatures, relative stabilities, melting points, rotatory power, and historical remarks on the stereoisomerism of polyenes. The text then ponders on the preparation of cis carotenoids by direct rearrangement of the all-trans form and total synthesis and naturally occurring cis and polycis carotenoids. The manuscript examines some general remarks on configurational assignments, configurational assignments in certain stereoisomeric sets, and lower-molecular weight carotenoid-carboxyli... acids. Topics include bixin set, stereoisomeric sets with two aromatic terminal groups, stereoisomeric sets with one hydroaromatic and one aliphatic terminal group, configuration and infrared spectrum, and stereoisomeric types. The manuscript also elaborates on vitamins A and retinenes, cumulenes with aromatic terminal groups, and polyene azines. The publication is a dependable source of information for researchers interested in cis-trans isomeric carotenoids, vitamins A, and arylpolyenes.

      In complex macromolecules, minor modifications can generate major changes, due to self-assembling capacities of macromolecular or supramolecular networks. Controlled Drug Delivery highlights how the multifunctionality of several materials can be achieved and valorized for pharmaceutical and biopharmaceutical applications. Topics covered in this comprehensive book include: the concept of self-assembling; starch and derivatives as pharmaceutical excipients; and chitosan and derivatives as biomaterials and as pharmaceutical excipients. Later chapters discuss polyelectrolyte complexes as excipients for oral administration; and natural semi-synthetic and synthetic materials. Closing chapters cover protein-protein associative interactions and their involvement in bioformulations; self-assembling materials, implants and xenografts; and provide conclusions and perspectives.

Chapters detail the characteristics of light sources and object colour and appearance attributes. They encompass the complexities of human visual perception, including the various causes and types of colour blindness, and other unusual visual phenomena. The book also covers colour measurement instruments and methods, as well as fluorescence and whiteness. Principles of Colour Appearance and Measurement is a comprehensive resource for designers, colour technologists, colour quality inspectors, product developers, and anyone who uses colour in their work.

      Metabolic Conjugation and Metabolic Hydrolysis, Volume I is a comprehensive account of the main conjugation mechanisms and hydrolytic reactions. Topics covered range from the metabolic conjugates of steroids and N-hydroxy compounds to the effects of conjugated steroids on enzymes. The glucuronic acid pathway is also discussed, along with sulfoconjugation and sulfohydrolysis. Comprised of eight chapters, this volume first looks at the history of conjugation mechanisms before proceeding to developments in metabolic conjugations. The isolation, recognition, enzymic formation and hydrolysis, and the possible significance of steroid N-acetylglucosaminid... and glucosides are considered. The book also examines the mechanisms involved in the enzymic formation of N-hydroxy compounds; the pathways by which N-hydroxy compounds may be further metabolized in vivo; and the chemical properties of conjugates of N-hydroxy compounds, particularly as these properties are related to the generation of reactive cations or free radicals in vivo. The possible role of conjugates of N-hydroxy compounds in the mechanism of carcinogenesis by aromatic amines and their N-acyl derivatives is also analyzed. Finally, glycoprotein and mucopolysaccharide hydrolysis and the role of hydrolases in cellular death are described. This monograph will be a useful resource for biologists, biochemists, physiologists, and pharmacologists.

      Advances in Lipid Research, Volume 23 provides information pertinent to mammalian as well as plant metabolism. This book presents important data on apoproteins, which may offer a foothold for further probes of the genetics underlying increased susceptibility to ischemic heart disease. Organized into seven chapters, this volume begins with an overview of the molecular biology of human apolipoproteins B and E. This text then explains the lipid metabolism of dermatophytes and describes their lipid composition and how it may be modulated. Other chapters consider the function, distribution, and biosynthesis of the sterols of fungi and examine the influences of fungal sterols on membrane fluidity. This book discusses as well the biosynthesis and degradation of platelet-activating factor (PAF) as well as its physiological function. The final chapter deals with one specific area of PAF activity, namely, renal processes. This book is a valuable resource for biologist, biochemists, chemists, and clinicians.
