Free Radical Biology in Digestive Diseases

There is a growing body of experimental and clinical data to suggest that the organs of the digestive system may be subjected to considerable oxidative stress associated with acute and chronic inflammation. Although inflammation and ischemia play a key role in producing oxygen-derived free radicals in the digestive tract, the contribution of other factors, such as transition metal imbalances, lipid and glucose metabolic disturbance, and the interaction with gaseous molecules including nitric oxide and carbon monoxide, has also been suggested. Recent studies have demonstrated that several biomarkers indicating oxidative stress-mediated damage may help in monitoring the degree of disease and p...

Oxygen Transport to Tissue XXXI

The International Society on Oxygen Transport to Tissue (ISOTT, www. isott. info) is an interdisciplinary society comprising about 250 members worldwide. Its purpose is to further the understanding of all aspects of the processes involved in the transport of oxygen from the air to its ultimate consumption in the cells of the various organs of the body. The annual meeting brings together scientists, engineers, clinicians and mathematicians in a unique int- national forum for the exchange of information and knowledge, the updating of participants on latest developments and techniques, and the discussion of controversial issues within the field of oxygen transport to tissue. Founded in 1973, th...

Molecular Basis for Microcirculatory Disorders

A large number of cardiovascular diseases are accompanied by inflammation. This volume on the molecular basis of microcirculatory disorders gives a comprehensive summary of key steps in the inflammatory cascade. Leading investigators present a state-of-the-art analysis of the molecular determinants of leukocyte-endothelial cell adhesion, mechanotransduction in endothelial and inflammatory cells, mechanisms of cell activation, microvascular apoptosis with applications to ischemia-reperfusion in the brain, the heart and in venous disease, diabetes and hypertension. The book provides the latest thinking in these important cardiovascular problems, with the most contemporary literature and a look at the increasingly complex events during inflammation. Molecular biology tools, microvascular and modern bioengineering analysis are seamlessly integrated into the analysis of clinical problems. The book helps not only newcomers to gain entry into the interesting problems associated with microvascular disorders, but lays the foundation for the design of new therapeutic interventions.

Oxidative Stress and Digestive Diseases

In the 1980s, biochemists and biologists were attracted by the role of reactive oxygen species in the irreversible damage or modification of the structure of biological molecules. However, in the 1990s, reactive oxygen species have been recognized to be involved in reversible structural alterations of molecules: The homeostatic modulation of oxidant levels is a highly efficient mechanism that allows all cells to tightly control their redox status within a very narrow range. Especially the activity of the Rel/NF-kB family of transcriptional factors that regulate responses in inflammation, reperfusion injury and apoptosis is controlled by intracellular reactive oxygen species levels. Our understanding of how these transcriptional factors are negatively or positively regulated by oxidative stress has since greatly increased. Questions for future investigation center on the modulation of oxidative stress by personal genome information for the prevention of several pathologic states.

Organ Microcirculation

The concept of microcirculation means not only the assembly of small vessels-those of less than 100 um in diameter, but also its functional circulatory and metabolic units. Its principal function is to permit the transfer of substances between the tissues and the circulation, making it a fundamental factor in disease processes, including the spread of cancer, delayed healing, circulatory shock, and complications of diabetes . Organ Microcirculation: A Gateway to Diagnostic and Therapeutic Interventions covers the latest developments in nano-biotechnology for microvascular interventions, gastroduodenal microcirculation and disease, liver microvascular research, cell adhesion and traffic in micmcirculation, and the sensing and bioregulation of gaseous molecules in microcirculation . It provides invaluable information for those engaged in microvascular research in the fields of pharmacology, physiology, gastroenterology, and bioengineering.

Gas Biology Research in Clinical Practice

An overview on the role of various gaseous molecules in health and disease The substantial biological importance of gaseous mediators in various physiological-pathological conditions has been realized only recently, but to date, the detailed mechanisms involved remain elusive. The publication at hand contains 16 overviews written by a panel of experts who summarize the current knowledge and provide fundamental insights into the roles of gaseous molecules in signal transduction in biological systems. The first part provides a comprehensive overview on gaseous mediators in health and disease. In the second part, the medical application of various molecules such as nitric oxide, carbon monoxide, hydrogen sulfide, hydrogen, acetone and phytoncide are discussed. Furthermore, articles on skin gas biology and Carbon-13 (13C), especially clinical applications of 13C-labeled substrate are included. This book provides valuable information not only for basic researchers in physiology and biochemistry, but also for gastroenterologists and clinicians who wish to learn more about the role of gaseous mediators.

Vascular Endothelium in Health and Disease

In recent years there has been rapid progress in research on vascular endothelium. This has led to significant advances in our understanding of the structure and function of vascular endothelium in health and disease, including such aspects as the permeability of endothelium in relation to its ultrastructural correlates, theoretical basis, regulatory factors, and role in atherogenesis; the interaction between endothelium and blood cells; the endothelial release and processing of a number of important physiological agents, such as eicosanoids, hemostatic factors, and histamine; the cell biology of endothelium with respect to the cytoskeletal apparatus, cell activation, and cell locomotion; an...
