Reports observations and findings using PET, SPECT, and other imaging technologies to identify tissue that is not getting sufficient oxygen, which can enhance the development and progress of disease and increase the resistance of tumors to radiation therapy. Nine papers from a workshop in Tubingen-Buhl, Germany in 1995 consider such aspects as the biology of technetium-based hypoxic tissue localizing compounds, molecular design approaches of hypoxia tracers, pre-clinical and clinical studies of quantifying hypoxia with radiolabeled fluoromisonidazole, and evaluating hypoxia in diabetes.

This open access book describes marked advances in imaging technology that have enabled the visualization of phenomena in ways formerly believed to be completelyimpossible. These technologies have made major contributions to the elucidation of the pathology of diseases as well as to their diagnosis and therapy. The volume presents various studies from molecular imaging to clinical imaging. It also focuses on innovative, creative, advanced research that gives full play to imaging technology inthe broad sense, while exploring cross-disciplinary areas in which individual research fields interact and pursuing the development of new techniques where they fuse together. The book is separated into three parts, the first of which addresses the topic of visualizing and controlling molecules for life. Th e second part is devoted to imaging of disease mechanisms, while the final part comprises studies on the application of imaging technologies to diagnosis and therapy. Th e book contains the proceedings of the 12th Uehara International Symposium 2017, “Make Life Visible” sponsored by the Uehara Memorial Foundation and held from June 12 to 14, 2017. It is written by leading scientists in the field and is an open access publication under a CC BY 4.0 license.
The present book is an attempt to provide a detailed review of studies that clarify our current understanding of the role of hypoxia in the progression of primary cancer to metastatic disease. It will enable researchers to discover the critical cellular changes that occur under hypoxic conditions and play a role in metastatic dissemination, from the activation of hypoxia-inducible factors, HIF-1 and HIF-2, to the transcriptional profile changes that occur in cancer cells and promote cancer cell survival under detrimental conditions. Readers will discover the methods and challenges involved in imaging and quantifying the degree of hypoxia in a primary tumor. We will provide an understanding of the hypoxia-induced phenotypes that influence heterogeneity, alter the secretome and tumor microenvironment, modify cellular metabolism, and promote immune suppression and resistance to chemotherapy. Finally, we will uncover the therapeutic strategies that are being devised to target the hypoxic microenvironment in the hopes of preventing metastasis and improving the efficacy of standard-of-care cancer treatments. This work is an up to date source of information on the challenges and complexity of the hypoxic tumor microenvironment. Basic and translational scientists, post-doctoral fellows, graduate students, and those interested in how tumors metastasize will find this book a reference that details how hypoxia influences metastatic disease.
Heat shock proteins are emerging as important molecules in the development of cancer and as key targets in cancer therapy. These proteins enhance the growth of cancer cells and protect tumors from treatments such as drugs or surgery. However, new drugs have recently been developed particularly those targeting heat shock protein 90. As heat shock protein 90 functions to stabilize many of the oncogenes and growth promoting proteins in cancer cells, such drugs have broad specificity in many types of cancer cell and offer the possibility of evading the development of resistance through point mutation or use of compensatory pathways. Heat shock proteins have a further property that makes them tempting targets in cancer immunotherapy. These proteins have the ability to induce an inflammatory response when released in tumors and to carry tumor antigens to antigen presenting cells. They have thus become important components of anticancer vaccines. Overall, heat shock proteins are important new targets in molecular cancer therapy and can be approached in a number of contrasting approaches to therapy.
This book provides an essential overview of existing state-of-the-art quantitative imaging methodologies and protocols (intensity-based ratiometric and FLIM/ PLIM). A variety of applications are covered, including multi-parametric quantitative imaging in intestinal organoid culture, autofluorescence imaging in cancer and stem cell biology, Ca2+ imaging in neural ex vivo tissue models, as well as multi-parametric imaging of pH and viscosity in cancer biology. The current state-of-the-art of 3D tissue models and their compatibility with live cell imaging is also covered. This is an ideal book for specialists working in tissue engineering and designing novel biomaterial.
Hypoxia, i.e. insufficient availability of oxygen within the tissue, is a more serious problem than realized in clinical routine work, although a large variety of theoretical and experimental data give clearly proven indications. During incidences and progress of many types of diseases hypoxia may enhance development and progress of the disease and, furthermore, decrease chances of efficient treatment of, e.g., tumors. Hypoxic tumor cells are up to three times more resistant towards radiation therapy than normoxic cells. With a diagnostic tool such as provided by hypoxia tracers suitable for PET and SPECT imaging, the particular tissue situation becomes detectable and, thus, treatable. Although the clinical importance of hypoxia imaging is obviously great, to date neither the clinical nor the scientific community at an international level has focused many research activities on the hypoxia problem. As the result of a workshop held by the Section for Radiopharmacy in Tübingen, this book collects observations and findings in order to stimulate the on-going research resulting in important clinical applications. Hypoxia imaging is needed in areas of cardiology, neurology and oncology. Additional applications are to be expected in the field of diabetes, infections and organ transplantation. Therefore, the book addresses those who are basically involved in research in radiochemistry and radiopharmacy as well as those dealing with all biological aspects and facing direct clinical applications.
This book describes the methods of analysis and determination of oxidants and oxidative stress in biological systems. Reviews and protocols on select methods of analysis of ROS, RNS, oxygen, redox status, and oxidative stress in biological systems are described in detail. It is an essential resource for both novices and experts in the field of oxidant and oxidative stress biology.
This book describes the basics, the challenges and the limitations of state of the art brain tumor imaging and examines in detail its impact on diagnosis and treatment monitoring. It opens with an introduction to the clinically relevant physical principles of brain imaging. Since MR methodology plays a crucial role in brain imaging, the fundamental aspects of MR spectroscopy, MR perfusion and diffusion-weighted MR methods are described, focusing on the specific demands of brain tumor imaging. The potential and the limits of new imaging methodology are carefully addressed and compared to conventional MR imaging. In the main part of the book, the most important imaging criteria for the differential diagnosis of solid and necrotic brain tumors are delineated and illustrated in examples. A closing section is devoted to the use of MR methods for the monitoring of brain tumor therapy. The book is intended for radiologists, neurologists, neurosurgeons, oncologists and other scientists in the biomedical field with an interest in neuro-oncology.
Design of Pulse Oximeters describes the hardware and software needed to make a pulse oximeter, and includes the equations, methods, and software required for them to function effectively. The book begins with a brief description of how oxygen is delivered to the tissue, historical methods for measuring oxygenation, and the invention of the pulse oximeter in the early 1980s. Subsequent chapters explain oxygen saturation display and how to use an LED, provide a survey of light sensors, and review probes and cables. The book closes with an assessment of techniques that may be used to analyze pulse oximeter performance and a brief overview of pulse oximetry applications. The book contains useful worked examples, several worked equations, flow charts, and examples of algorithms used to calculate oxygen saturation. It also includes a glossary of terms, instructional objectives by chapter, and references to further reading.
The collection of chapters in this proceeding volume reflects the latest research presented at the Aegean meeting on Tumor Microenvironment and Cellular Stress held in Crete in Fall of 2012. The book provides critical insight to how the tumor microenvironment affects tumor metabolism, cell stemness, cell viability, genomic instability and more. Additional topics include identifying common pathways that are potential candidates for therapeutic intervention, which will stimulate collaboration between groups that are more focused on elucidation of biochemical aspects of stress biology and groups that study the pathophysiological aspects of stress pathways or engaged in drug discovery.
