Structure
The Bacteria: Volume I: Structure deals with the structure of bacteria and covers topics ranging from the composition and organization of the bacterial protoplasm to the movement of bacteria, morphology of bacterial spores, and bacterial protoplasts. The internal structure and surface layers of the bacterial cell are also discussed together with L-forms of bacteria, bacterial viruses, and localization of bacterial enzymes. This volume is comprised of 10 chapters and begins with an overview of cell theory and the theory of the unity of biochemistry, followed by an analysis of the composition and organization of the bacterial protoplasm. The next chapter explores the internal structure of bact...
Bacterial Chromatin
This book brings together various contributions aimed at the elucida tion of the structural and functional organization of the bacterial nucleoid. Most of these papers, spanning the fields of physical chemistry through biochemistry to genetics, were presented at the session on bac terial chromatin during the Symposium "Selected topics on chromatin structure and function" held at the University of Camerino, Italy, at the end of May 1985. Times when the bacterial DNA was regarded as "naked" or, at most, complexed with polyamines, and when the absence of histones and organized chromatin was considered to be a distinct feature of the pro karyotic cell, now appear remote. Our concepts of how DNA is packaged in bacteria are changing rapidly. Studies on the structure of the bacterial nucleoid are not new. Recently, however, investigations in this field have flourished again, leading to some important contributions such as the elucidation of the three-dimensional structure of what appears to be the major protein constituent of the bacterial nucleoid or the development of methods to titrate the extent of DNA supercoiling within the bacterial cell.
Cryotechniques in Biological Electron Microscopy
To preserve tissue by freezing is an ancient concept going back pre sumably to the practice of ice-age hunters. At first glance, it seems as simple as it is attractive: the dynamics of life are frozen in, nothing is added and nothing withdrawn except thermal energy. Thus, the result should be more life-like than after poisoning, tan ning and drying a living cell as we may rudely call the conventional preparation of specimens for electron microscopy. Countless mishaps, however, have taught electron microscopists that cryotechniques too are neither simple nor necessarily more life-like in their outcome. Not too long ago, experts in cryotechniques strictly denied that a cell could truly be vitrified, i.e. that all the solutes and macro molecules could be fixed within non-crystalline, glass-like solid water without the dramatic shifts and segregation effects caused by crystallization. We now know that vitrification is indeed pos sible. Growing insight into the fundamentals of the physics of water and ice, as well as increasing experience of how to cool cells rapidly enough have enlivened the interest in cryofixation and pro duced a wealth of successful applications.
Principles of Biomolecular Organization
The Novartis Foundation Series is a popular collection of the proceedings from Novartis Foundation Symposia, in which groups of leading scientists from a range of topics across biology, chemistry and medicine assembled to present papers and discuss results. The Novartis Foundation, originally known as the Ciba Foundation, is well known to scientists and clinicians around the world.
EJB Reviews 1990
In the mid-1980s the European Journal of Biochemistry set out to publish review articles. The enterprise proved successful resulting in high-level reviews written by well-known scientists appearing in the Journal. The reviews represent emerging and rapidly growing fields of research in fundamental as well as applied areas of biochemistry, such as medicine, biotechnology, agriculture and nutrition. Novel methodological and technological approaches which stimulate biochemical research are also included. The authors of the reviews are explicitly asked to be critical, selective, evaluative and interdisciplinarily oriented. The reviews should encourage young scientists toward independent and creative thinking, and inform active investigators about the state of the art in a given field.
Progress in Nucleic Acid Research and Molecular Biology
Nucleic acids are the fundamental building blocks of DNA and RNA and are found in virtually every living cell. Molecular biology is a branch of science that studies the physicochemical properties of molecules in a cell, including nucleic acids, proteins, and enzymes. Increased understanding of nucleic acids and their role in molecular biology will further many of the biological sciences including genetics, biochemistry, and cell biology. Progress in Nucleic Acid Research and Molecular Biology provides a forum for discussion of new discoveries, approaches, and ideas in molecular biology. It contains contributions from leaders in their fields and abundant references.

The Biochemistry and Physiology of Bone
The Biochemistry and Physiology of Bone focuses on the advancements of techniques, methodologies, and approaches involved in bone studies, including general anatomy, tissues, collagen fibers, and calcification. The selection first offers information on the general anatomy and histology of bone and bone as a mechanical engineering problem. Topics include strength of healing fractures, nervous influences on bone, growth of the skull, bone strength, primary constituents of bony tissue, and types and organization of bony tissue. The text then elaborates on the ground substance of connective tissue and cartilage, organic matrix of bone, and collagen fibers of connective tissue. The publication ta...
