PEGylation technology and key applications are introduced by this topical volume. Basic physical and chemical properties of PEG as basis for altering/improving in vivo behaviour of PEG-conjugates such as increased stability, improved PK/PD, and decreased immunogenicity, are discussed. Furthermore, chemical and enzymatic strategies for the coupling and the conjugate characterization are reported. Following chapters describe approved and marketed PEG-proteins and PEG-oligonucleotides as well as conjugates in various stages of clinical development.

Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.

"Sun Protection in Man" looks at the beneficial and harmful effects of solar radiation. The physiological consequences of sun exposure have been systematically studied starting at the end of the nineteenth century and we now have accumulated knowledge about how Caucasian and Asian skins reacts to solar radiation. The chemical effects of solar ultraviolet radiation have been analyzed with particular emphasis during the second half of the twentieth century. Research on micro-organisms has allowed us to understand the mechanisms of UV-induced mutagenesis and photosensitization. Studies with laboratory rodents have opened the path to the understanding of UV-induced immune-depression, carcinogenesis, photo-damage and photo-aging. The results of these studies have enabled other scientists to investigate the same phenomena in human organs such as the skin and the eye. UV radiation damages hair, as well. The present knowledge in these fields is summarized in some of the chapters of this monograph.Mass phenomenon in Europe with the generalization of summer vacations which were a consequence of social reforms introducing the concept of "paid vacations". This created a need for protection and opened a market for sunscreens. This monograph is concerned with sun protection as a whole and is not just "another book on sunscreens". Nonetheless, in these days of general concern, it is important to learn about the efficiency of sunscreens. Several authors discuss how to reduce the number of impinging photons and explain why sunscreens seem to offer less protection than expected. Guidelines are given on how to use sunscreens in everyday life, which are expressed rigorously though clearly, for access to the common reader.Our knowledge on the relationship between sun and humans is at the early stages of development. Industrial and commercial activities are concerned by the development of this knowledge, and rules have been and will be promulgated to guarantee efficacy and safety of sun-products. It is hoped that this monograph will be of interest to the scholar, the layman and the legislator.

The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.

This unique book will provide an up to date and comprehensive account of the potential of peptides and proteins from animal venoms as possible therapeutics. The pharmaceutical industry has become increasingly interested in biologics from animal venoms as a potential source for therapeutic agents in recent years, with a particularly emphasis on peptides. To date six drugs derived from venom peptides or proteins have been approved by the FDA, with nine further agents currently being investigated in clinical trials. In addition to these drugs in approved or advanced stages of development, many more peptides and proteins are being studied in varying stages of preclinical development. Topics covered include chemistry and structural biology of animal venoms, proteomic and transcriptomic approaches to drug discovery, bioassays, high-throughput screens and target identification, and reptile, scorpion, spider and cone snail venoms as a platform for drug development. Case studies are used to illustrate methods and successes and highlight issues surrounding administration and other important lessons that have been learnt from the development of approved therapeutics based on venoms. The first text to focus on this fascinating area and bridging an important gap, this book will provide the reader with essential and current knowledge on this fast-developing area. Venoms to Drugs will find wide readership with researchers working in academia and industry working in all medicinal and pharmaceutical areas.

Antibody-drug conjugates (ADCs) stand at the verge of a transformation. Scores of clinical programs have yielded only a few regulatory approvals, but a wave of technological innovation now empowers us to overcome past technical challenges. This volume focuses on the next generation of ADCs and the innovations that will enable them. The book inspires the future by integrating the field’s history with novel strategies and cutting-edge technologies. While the book primarily addresses ADCs for solid tumors, the last chapter explores the emerging interest in using ADCs to treat other diseases. The therapeutic rationale of ADCs is strong: to direct small molecules to the desired site of action (and away from normal tissues) by conjugation to antibodies or other targeting moieties. However, the combination of small and large molecules imposes deep complexity to lead optimization, pharmacokinetics, toxicology, analytics and manufacturing. The field has made significant advances in all of these areas by improving target selection, ADC design, manufacturing methods and clinical strategies. These innovations will inspire and educate scientists who are designing next-generation ADCs with the potential to transform the lives of patients.
