For many years, it has been known that when rats and mice are given a reduced amount of food, their life span is increased and they remain healthy and vigorous at advanced ages.

What is the reason for this change in the usual pattern of aging? The evidence is overwhelming that the life extension results from a slowing of aging processes. And the factor responsible is the decrease in caloric intake. The obvious question: How does this factor work? A good question - and the reason that research on the anti-aging action of caloric restriction is today one of the most studied research areas in biological gerontology. For it is felt that if the biological mechanisms of the anti-aging action of caloric restriction can be uncovered, we would gain an understanding of the basic nature of aging processes, which would, in turn, yield possible interventions in human aging. This book aims to provide the growing number of researchers in this field (faculty, postdoctoral trainees, and graduate students) with a detailed knowledge of what is known about caloric restriction within the frame of gerontology, as well as insights on future of this field.

This thesis describes a series of investigations designed to assess the value of metalloenzymes in systems for artificial and adapted photosynthesis. The research presented explores the interplay between inherent enzyme properties such as structure, rates and thermodynamics, and the properties of the semiconducting materials to which the enzyme is attached. Author, Andreas Bachmeier provides a comprehensive introduction to the interdisciplinary field of artificial photosynthesis, allowing the reader to grasp the latest approaches being investigated, from molecular systems to heterogeneous surface catalysis. Bachmeier's work also uses metalloenzymes to highlight the importance of reversible catalysts in removing the burden of poor electrocatalytic rates and efficiencies which are common characteristics for most artificial photosynthesis systems. Overall, this thesis provides newcomers and students in the field with evidence that metalloenzymes can be used to establish new directions in artificial photosynthesis research.

The work described in this book is an excellent example of interdisciplinary research in systems biology. It shows how concepts and approaches from the field of physics can be efficiently used to answer biological questions and reports on a novel methodology involving creative computer-based analyses of high-throughput biological data. Many of the findings described in the book, which are the result of collaborations between the author (a theoretical scientist) and experimental biologists and between different laboratories, have been published in high-quality peer-reviewed journals such as Molecular Cell and Nature. However, while those publications address different aspects of post-transcriptional gene regulation, this book provides readers with a complete, coherent and logical view of the research project as a whole. The introduction presents post-transcriptional gene regulation from a distinct angle, highlighting aspects of information theory and evolution and laying the groundwork for the questions addressed in the subsequent chapters, which concern the regulation of the transcriptome as the primary functional carrier of active genetic information.

This volume presents a collection of reviews derived from work presented at the Aegean Conference: "5th Crossroads Between Innate and Adaptive Immunity". This meeting was the fifth in a series, and assembled a team of scientists working on mechanisms by which the innate immune system of the host senses pathogens, the cellular and signaling networks that orchestrate the innate response and antigen presentation and adaptive immunity. The importance of the crosstalk between innate immunity and the adaptive immune response has only recently started to be appreciated. Although it is well recognized that dendritic cells, NK cells, NK-T cells and T cells are all critical for the host response to pathogens, the respective fields that study the biology of these immune cells tend to exist in parallel worlds with minimum exchange of information and ideas. This fragmentation hinders the integration of these fields towards a unified theory of host response. The Aegean Conference "Crossroads between Innate and Adaptive Immunity" brought together leading international scientists and experts to address critical areas of Innate and Adaptive Immunity, a necessary step in the development of more efficient scientific exchange and crosspollination between these fields. This conference attracted scientists from all over the world to discuss their latest findings on the various aspects of Innate and Adaptive Immunity, and maximized scientific interchange through lecture presentations, poster sessions and informal discussions.

The discovery of vitamins in the early 1900s, their later chemical characterization and the clarification of pivotal metabolic functions are sequential aspects of a brilliant chapter in the history of modern nutritional sciences and medicine. The name, derived from "vital-amines", indicates their elementary metabolic key functions in human metabolism. Vitamins are truly families of compounds, which include precursors and various free and bound forms, all with individual roles in metabolism and function. A more recent approach therefore searches for the components, the understanding of their roles in physiology and pathology as well as looking for novel pharmacological applications. When used properly, vitamins are, indeed, "magical" substances. Due to their efficacy, they should therefore be regarded as drugs with effects and side effects to be weighted against each other. Today, it is not the previously fatal deficiency-associated diseases that are in the focus of interest, but rather the relation of suboptimal vitamin bioavailability to chronic disease. This is complicated by genetic susceptibility, lifestyle, and the presence or absence of health-compromising habits, such as smoking. In turn, the development and application of new and more sensitive and specific assays further enable us to look more closely into the many functions of vitamins. Water soluble vitamins are complex molecular structures and even today, many areas in vitamin biochemistry are not yet fully understood. Novel effects and functions of vitamins remain and continue to be discovered. This book presents most recent research results and fascinating new knowledge on the role and effects of the water soluble vitamins in man. Some of the most distinguished chemists, biochemists, biologists and clinicians have contributed valuable chapters sharing unexpected novel insights into the biochemistry, (epi)genetics, metabolism, and function of water soluble vitamins, with their potential for clinical applications. Thus, physicians, clinicians, scientists, researchers, epidemiologists. nutritional specialists and health professionals alike will find stimulating and fascinating new insight in the many roles that water soluble vitamins play in human health and disease.

There is no other comparable book; MILS-6, written by 17 experts, summarizes the most recent insights into this fascinating topic.

This book reviews the fundamental aspects of quinoxaline chemistry: synthesis, reactions, mechanisms, structure, properties, and uses. The first four chapters present a survey of the developments in quinoxaline chemistry since the publication of the monograph on "Condensed Pyrazines" by Cheeseman and Cookson in 1979. These chapters give comprehensive coverage of all the methods of the synthesis of quinoxalines and the important quinoxaline-containing ring systems such as thiazolo[3,4-a]-, pyrrolo[1,2-a]-, and imidazo[1,5-a]quinoxalines. Chapter five describes many new methods for the construction of quinoxaline macrocycles, which are important in applications such as optical devices and materials. The final chapter reviews all previously known rearrangements of heterocyclic systems that lead to benzimidazole derivatives. Mamedov critically analyses these transformations to reveal a novel acid-catalyzed rearrangement of quinoxalinones giving 2-heteroarylbenzimidazoles and 1-heteroarylbenzimidazolones in the presence of nucleophilic reactants (MAMEDOV Heterocycle Rearrangement). This book is of interest to researchers in the fields of heterocyclic and synthetic organic chemistry.
