Book Description
The fluid-mosaic model of membrane structure formulated by Singer and Nicolson in the early 1970s has proven to be a durable concept in terms of the principles governing the organization of the constituent lipids and proteins. During the past 30 or so years a great deal of information has accumulated on the composition of various cell membranes and how this is related to the dif ferent functions that membranes perform. Nevertheless, the task of explaining particular functions at the molecular level has been hampered by lack of struc tural detail at the atomic level. The reason for this is primarily the difficulty of crystallizing membrane proteins which require strategies that differ from those used to crystallize soluble proteins. The unique exception is bacteriorhodopsin of the purple membrane of Halobacterium halobium which is interpolated into a membrane that is neither fluid nor in a mosaic configuration. To date only 50 or so membrane proteins have been characterised to atomic resolution by diffraction methods, in contrast to the vast data accumulated on soluble proteins. Another factor that has been difficult to explain is the reason why the lipid compliment of membranes is often extremely complex. Many hundreds of different molecular species of lipid can be identified in some membranes. Remarkably, the particular composition of each membrane appears to be main tained within relatively narrow limits and its identity distinguished from other morphologically-distinct membranes.

Book Description
A Comprehensive Guide to Crucial Attributes of Therapeutic Proteins in Biological Pharmaceuticals With this book, Dr. Raju offers a valuable resource for professionals involved in research and development of biopharmaceutical and biosimilar drugs. This is a highly relevant work, as medical practitioners have increasingly turned to biopharmaceutical medicines in their search for safe and reliable treatments for complex diseases, while pharmaceutical researchers seek to expand the availability of biopharmaceuticals and create more affordable biosimilar alternatives. Readers receive a thorough overview of the major co-translational modifications (CTMs) and post-translational modifications (PTMs) of therapeutic proteins relevant to the development of biotherapeutics. The majority of chapters detail individual CTMs and PTMs that may affect the physicochemical, biochemical, biological, pharmacokinetic, immunological, toxicological etc. properties of proteins. In addition, readers are guided on the methodology necessary to analyze and characterize these modifications. Thus, readers gain not only an understanding of CTMs/PTMs, but also the ability to design and assess their own structure-function studies for experimental molecules. Specific features and topics include: Discussion of the research behind and expansion of biopharmaceuticals Twenty chapters detailing relevant CTMs and PTMs of proteins, such as glycosylation, oxidation, phosphorylation, methylation, proteolysis, etc. Each chapter offers an introduction and guide to the mechanisms and biological significance of an individual CTM or PTM, including practical guidance for experiment design and analysis An appendix of biologic pharmaceuticals currently on the market, along with an assessment of their PTMs and overall safety and efficacy This volume will prove a key reference on the shelves of industry and academic researchers involved in the study and development of biochemistry, molecular biology, biopharmaceuticals and proteins in medicine, particularly as biopharmaceuticals and biosimilars become ever more prominent tools in the field of healthcare.

Book Description
Chagas disease causes severe socioeconomic impact and a high medical cost in Latin America. WHO and the World Bank consider Chagas disease as the fourth most transmittable disease to have a major impact on public health in Latin America: 120 million persons are potentially exposed, 16 to 18 million of whom are presently infected, causing 45,000 to 50,000 deaths per year. It has been calculated that approximately 2.4 million potential working years are lost because of incapacity and mortality due to the disease, for an annual cost estimated at 20 billion Euros. American Trypanosomiasis provides a comprehensive overview of Chagas disease and discusses the latest discoveries concerning the three elements that compose the transmission chain of the disease: - The host: human and mammalian reservoirs - The insect vectors: domestic and sylvatic vectors - The causative parasite: Trypanosoma cruzi - Informs and updates on all the latest developments in the field - Contributions from leading authorities and industry experts

Book Description
Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.
