The ability of cells to sense and respond to changes in oxygenation underlies a multitude of developmental, physiological, and pathological processes. This volume provides a comprehensive compendium of experimental approaches to the study of oxygen sensing in 48 chapters that are written by leaders in their fields.
In the liver, nutrients taken up from food are utilized for the synthesis of different components of the body, and the waste matter and harmful substances produced are disposed or detoxicated. These functions of the liver must be regulated in accordance with the state of the body. The nervous system plays this regulatory role, one which is reminiscent of the production management system in a factory.
This is the fifth symposium on Experimental and Clinical Hepatology to be convened by the organisers, and, in common with the previous four, reflects the importance placed upon continuing discussion by clinical investigators as well as basic physiological and pharmacological researchers. Previous meetings which were held at the Surgical Department of the Philipps University in Marburg were dedicated to problems of direct clinical application, such as haemodynamics of portal hypertension, surgical approach to hepatic tumours, liver regeneration and temporary hepatic support. Clinical investigation was a subject which frequently came under discussion and some of these investigations have since...
International experts are brought together in this book to give basic as well as clinical data on obesity and cachexia, and an integrated picture of the regulation of intermediary metabolism in both situations. The data provide evidence that tissue catabolism and anabolism are regulated by similar mechanisms, which again are the target of different hormonal and metabolic factors. This joint discussion of the similarities evident in both areas will greatly benefit future understanding and research in obesity and cachexia.
Global warming, pollution, food and water shortage, cyberspace insecurity, over-population, land erosion, and an overburdened health care system are major issues facing the human race and our planet. These challenges have presented a mandate to develop “natural” or “green” technologies using nature and the living system as a guide to rationally design processes, devices, and systems. This approach has given rise to a new paradigm, one in which innovation goes hand-in-hand with less waste, less pollution, and less invasiveness to life on earth. Bioinspiration has also led to the development of technologies that mimic the hierarchical complexity of biological systems, leading to novel ...
self-assembly and responsiveness of cellular systems; the biomineral formation in bacteria, plants, invertebrates, and vertebrates; the multi-layer structure of skin; the organization of tissue fibers; DNA structures with metal-mediated artificial base pairs; and the anisotropic microstructure of jellyfish mesogloea. In this volume, sensor and microfluidic technologies combined with surface patterning are explored for the diagnosis and monitoring of diseases. The high throughput combinatorial testing of biomaterials in regenerative medicine is also covered. The second volume presents nature-oriented studies and developments in the field of electromechanical devices and systems.
In aerobic tissues such as heart, brain, kidney, liver and brown fat, mitochon dria account for more than 20% of cell protein and play an essential role in res piration, ATP formation, ketogenesis, gluconeogenesis, amino acid metabolism, ureagenesis, thermogenesis and a variety of other metabolic activities. The mecha nisms by which these activities are integrated and regulated within the overall context of cellular physiology is of much current research interest. In order to bring together scientists examining the various diverse aspects of this overall pro blem, an International Conference on INTEGRATION OF MITOCHONDRIAL FUNC TION was held June 4-7, 1987 at the Hanes Art Center on the campus of the Uni versity of North Carolina at Chapel Hill. The chapters of this volume derive from presentations made at this conference. The focus of INTEGRATION OF MITOCHONDRIAL FUNCTION is on signifi cant new experimental and theoretical advances concerning integration of mito chondrial function at the organelle, cell, tissue and whole organism levels of organization.
The meeting on experimental hepatocarcinogenesis which took place in Spa, Belgium at the end of May 1987 was the Second European Meeting. About 100 scientists, mostly from Europe but also from the United States, met there for three days in a very friendly atmosphere to exchange knowledge and ideas on experimental and human liver carcinogenesis. The main topics discussed during the meeting included general reviews on hepatocarcinogenesis, experimental models of hepa tocarcinogenesis, biology of hepatocarcinogenesis, and in vitro studies in hepatocarcinogenesis. They are all covered by the various chapters of this proceedings volume, which reflects the present state of knowledge in this import...
The hepatocyte adapts its metabolic and excretory function to changes in nutrient supply, xenobiotics, cytokines and hormones, which provides a basis for the role of the liver in the maintenance of the body's homeostasis. Such adaptations of hepatocellular function to the environment require not only structures for recognition of signal molecules and for the sensing of environmental alterations, but also machineries which transfer this information to intracellular effector sites. Considerable progress has been made during recent years with respect to the understanding of membrane-associated receptor systems and the molecular mechanisms by which signals are transduced from these receptors to ...
MILS-14 provides a most up-to-date view of the exciting biogeochemistry of gases in our environment as driven mostly by microorganisms. These employ a machinery of sophisticated metalloenzymes, where especially transition metals (such as Fe, Ni, Cu, Mo, W) play a fundamental role, that is, in the activation, transformation and syntheses of gases like dihydrogen, methane, carbon monoxide, acetylene and those of the biological nitrogen and sulfur cycles. The Metal-Driven Biogeochemistry of Gaseous Compounds in the Environment is a vibrant research area based mainly on structural and microbial biology, inorganic biological chemistry and environmental biochemistry. All this is covered in an auth...
