Bioelectric Power and Work in Gastro intestinal Tissue

Gastrointestinal Tissue: Oxidative Stress and Dietary Antioxidants brings together leading experts from world renowned institutions, combining the basic mechanisms of gastrointestinal diseases with information regarding new and alternative treatments. The processes within the science of oxidative stress are described in concert with other processes, including apoptosis, cell signaling and receptor mediated responses, further recognizing that diseases are often multifactorial with oxidative stress as a component. By combining the critical molecular processes underlying free radical mediated pathologies and the role of

This, the fifth volume in the Proteases in Biology and Disease series, is devoted to Proteases in Gastrointestinal Tissues. Of course, proteases play an important role in the digestion and utilization of ingested proteins, but besides that they elicit a wide range of physiological and pathological effects. Proteases have been recognized as essential regulators, acting both locally and systemically, of normal development, growth and functioning. Dysregulation of protease expression and/or enzymatic activity is often associated with the onset or

The microcirculation of the gastrointestinal tract is under the control of both myogenic and metabolic regulatory systems. The myogenic mechanism contributes to basal vascular tone and the regulation of transmural pressure, while the metabolic mechanism is responsible for maintaining an appropriate balance between O2 demand and O2 delivery. In the postprandial state, hydrolytic products of food digestion elicit a hyperemia, which serves to meet the increased O2 demand of nutrient assimilation. Metabolically linked factors (e.g., tissue pO2, adenosine) are

In recent years, there have been significant advances both in understanding the mechanisms involved in gastrointestinal mucosal injury and protection, as well as in the development of successful strategies for prevention and treatment of gastrointestinal injury. Nevertheless, many people worldwide still suffer from gastrointestinal damage.This book contains contributions by an international panel of researchers in the form of up-to-date reviews on the mechanisms of gastrointestinal injury and protection. These are complemented by papers discussing how these new findings about

This issue should serve as a primer to endoscopists who are seeking state-of-the-art clinical guidance on endoscopic ultrasound tissue acquisition. Authors address the changing paradigm in EUS-guided tissue acquisition and when does the oncologist require core tissue? Articles offer a comprehensive look at the core topics, including definitions in tissue acquisition, selection of FNA needles, and techniques for EUS-guides FNA and FNB. Expert authors also give their recommendations for overcoming technical challenges in EUS-guided tissue acquisition and what the pitfalls

Biomechanics of the Gastrointestinal Tract is an up-to-date book for researchers on the study of the mechanical properties and the motor system of the gastrointestinal tract. A well-illustrated book, it provides a comprehensive overview to relevant tissue geometry, morphology and biomechanical theory. Separate chapters cover smooth muscle and nerve function including the application to animal and human studies of motility, symptoms and pain, determination of the true resting state, history-dependent properties, and tissue remodelling in disease. Several methods and diagnostic
