Buch. Zustand: Neu. Neuware - Progress in molecular technology in recent years has caused an amazing growth of information about intercellular peptide messengers and their receptors. The number of characterized interleukins for example numbered just three six years ago and now there are at least 16. In addition, the number of described neutrophic peptides is around 30 and the number of receptors is ever increasing. Because many of these new peptide ligands and receptors were identified by 'reverse genetic' techniques the understanding of their biological roles falls behind the knowledge of their molecular structures. However a new strain of functional studies has begun and animal models are developed allowing for further research into the biological roles of these messenger peptides and their receptors. Cytokines, the theme of this volume, describes a group of proteins identified primarily within the immune and hematopoietic systems. As many cytokines as possible are included along with their receptors providing the reader with a guide to an ever-changing field of scientific research. …

Buch. Zustand: Neu. Neuware - The collection of chapters in the Handbook of Population and Family Economics and their organization reflect the most recent developments in economics pertaining to population issues and the family. The rationale, contents, and organization of the Handbook evolve from three premises. First, the family is the main arena in which population outcomes are forged. Second, there are important interactions and significant causal links across all demographic phenomena. Third, the study of the size, composition, and growth of a population can benefit from the application of economic methodology and tools. The diversity and depth of the work reviewed and presented in the Handbook conveys both the progress that has been made by economists in understanding the forces shaping population processes, including the behavior of families, and the many questions, empirical and theoretical, that still remain.For more information on the Handbooks in Economics series, please see our home page on elsevier.nl/locate/hes.…
