Applications of microbial nanotechnology are currently emerging with new areas being explored. Biosynthesis of nanomaterials by microorganisms is a recently attracting interest as a new, exciting approach towards the development of 'greener' nanomanufacturing compared to traditional chemical and physical approaches. This book will cover recent advances of microbial nanotechnology in agriculture, industry, and health sectors.
The ubiquitin system has two major functions in eukaryotic cells: it r- ulates protein degradation, which is essential for normal cellular fu- tion and for the removal of potentially harmful, damaged, or misfolded proteins, and it controls protein activity by regulating protein-protein interactions and subcellullar localization. The ubiquitin system is thus involved in processes as diverse as cell cycle progression, signal tra- duction, gene transcription, and DNA repair. Not surprisingly, defects in the ubiquitin system have been linked with numerous diseases such as cancer, in?ammation, central nervous system disorders, and metabolic dysfunction. Ubiquitin is a highly conserved 76-amino acid protein which is transferred to its target protein in an ATP-dependent manner. This post-translational modi?cation takes place in a hierarchical, three-step fashion involving an E1 ubiquitin-activating enzyme, an E2 ubiquit- conjugating enzyme, and an E3 ubiquitin ligase. Substrate speci?city is predominantly controlled by members of a large family of E3 - zymes, which form complexes with the proteins that will be modi?ed. This ultimately leads to the covalent attachment of the C-terminus of ubiquitin to usually an?-amino group of a lysine residue in the targeted protein. Additional ubiquitin transfer to lysine-48 of ubiquitin itself will form a polyubiquitin chain, which usually targets the conjugate for degradation by the proteasome. By contrast, mono- or polyubiquityla- VI Preface tion involving lysine-63 is normally involved in the control of protein activity. Ubiquitylation can be reverted by deubiquitylating enzymes, of which approximately 95 exist in mammals.
Membrane processes today play a signifi cant role in the replacement therapy for acute and chronic organ failure diseases. Current extracorporeal blood purifi cation and oxygenation devices employ membranes acting as selective barriers for the removal of endogeneous and exogeneous toxins and for gas exchange, respectively. Additionally, membrane technology offers new interesting opportunities for the design of bioartificial livers, pancreas, kidneys, lungs etc. This book reviews the latest developments in membrane systems for bioartificial organs and regenerative medicine, investigates how membrane technology can improve the quality and efficiency of biomedical devices, and highlights the design procedures for membrane materials covering the preparation, characterization, and sterilization steps as well as transport phenomena. The different strategies pursued for the development of membrane bioartifi cial organs, including crucial issues related to blood/cell-membrane interactions are described with the aim of opening new and exciting frontiers in the coming decades. The book is a valuable tool for tissue engineers, clinicians, biomaterials scientists, membranologists as well as biologists and biotechnologists. It is also a source of reference for students, academic and industrial researchers in the topic of biotechnology, biomedical engineering, materials science and medicine.
The presentation and interpretation of visual information is essential to almost every activity in human life and most endeavors of modern technology. This book examines the current status of what is known (and not known) about human vision, how human observers interpret visual data, and how to present such data to facilitate their interpretation and use. Written by experts who are able to cross disciplinary boundaries, the book provides an educational pathway through several models of human vision; describes how the visual response is analyzed and quantified; presents current theories of how the human visual response is interpreted; discusses the cognitive responses of human observers; and examines such applications as space exploration, manufacturing, surveillance, earth and air sciences, and medicine. The book is intended for everyone with an undergraduate-level background in science or engineering with an interest in visual science. This second edition has been brought up to date throughout and contains a new chapter on "Virtual reality and augmented reality in medicine."
This uniquely accessible volume challenges professionals to understand-and help correct-health disparities, both at the patient level and in their larger social contexts. Dedicated to eradicating this ongoing injustice, contributors focus on marginalized populations, the role of healthcare systems in perpetuating inequities, the need for deeper engagement and listening by professionals, and the need for advocacy within professional education and the political/policy arena. The compelling case narratives at the core of the book illustrate the interrelated biopsychosocial components of patients' health problems and the gradations of learning needed for practitioners to address them effectively. The book's tools for developing a health disparities curriculum include a selection of workshop exercises, facilitator resources, and a brief guide to writing effective case narratives. A sampling of the narratives: "Finding the Person in Patient-Centered Health Care" (race/ethnicity/culture). "The Annual Big Girl / Big Boy Exchange" (gender). "Just Give Me Narcan and Let Me Go" (poverty/addiction). "Everyone Called Him Crazy" (immigration). "Adrift in the System" (disability). "Aging out of Pediatrics" (mental illness and stigma). "Time to Leave" (LGBT) A work of profound compassion, Health Disparities will be of considerable interest to researchers and practitioners interested in public health, population health, health disparities, and related fields such as sociology, social work, and narrative medicine. Its wealth of educational features also makes it a quality training text. "I was impressed when I read Health Disparities: Weaving a New Understanding through Case Narratives. As a patient who has experienced unpleasant situations in health care, I was moved to see that it was emotional and personal for the writers. The book confirms for me that the time is now for change to take place in our health care systems. I see this book as a light that can shine bright in the darkest places of health care. The editors have assembled a powerful book that provides all health professionals with specific steps they can take towards addressing and then eventually eliminating health disparities. A few steps that I really connected with were improving critical awareness, delivering quality care, listening and empathizing with patients and families, and advocating for changes. I recommend that anyone interested in working to improve health care obtain a copy of this book-it's filled with useful information that every medical professional should know. The book reminds me of a quote by Wayne Dyer, 'When you change the way you look at things, the things you look at change.'" -Delores Collins, Founder and Executive Director, A Vision of Change Incorporated, Certified Community Health Worker.

For one-semester courses in human anatomy. A functional approach to human anatomy Human Anatomy, the #1 best-selling textbook for the human anatomy course, is widely regarded as the most readable and visually accessible book on the market. Using a functional anatomy theme, the text presents human anatomy as a well-illustrated "story" with the right amount of detail that learners can understand at an introductory level. Analogies and comparative descriptions make anatomical structures more memorable and understandable and explain how the shape and composition of structures allow them to perform their functions. The 9th Edition features new exercises and questions that help students learn and use anatomical language and interpret real-world medical images while learning basic human anatomy. Building on the functional anatomy approach of previous editions, selected illustrated tables have been enhanced to tell a more cohesive and logical "story" of human anatomy.
Animal cells present an extreme variability in their shapes in relation to their physiological properties. For instance, fibroblastic cells are tightly attached to the extra-cellular matrix and display a flattened, spindle-shaped morphology. Neuronal cells self-organize as a network through a complex branching of dendrites and a long axonal extension. Resting peripheral blood lymphocytes are poorly adhesive and maintain a spherical, smooth shape, while macroph- ages produce many pseudopodal extensions involved in the recognition of foreign molecules. In addition to the variability of the morphology of the cells that constitute different organs, many cell types also modify dynamically their morphology in response to environmental changes, leading to differential cell motility, migration, adhesion, polarity or intercellular contacts. This wide plasticity of cell morphology is promoted and maintained by the cytoskeleton, which is composed of the three interconnected actin micro filaments, tubulin microtubules and intermediate filaments networks, all capable of assembly and disassembly. Over the past few years, the Rho family of Ras-like GTPases emerged as key proteins that mediate extracellular signalling pathways leading to the forma- tion of polymerized actin-containing structures such as ruffles, lamellipodia and filopodia. Since the discovery of the first member RhoA in 1985, 13 mem- bers have so far been characterized in human cells. Most of Rho proteins are highly conserved between species as distant as yeast, slime mold, insects and mammals, which points to their fundamental role in cellular physiology.

This volume illustrates the extent to which the traditional
distinction between biochemical and physiological processes is
being obliterated by molecular biology. It can hardly be doubted
that the revolution in cell and molecular biology is leading to
core knowledge that provides an outline of the integrative and
reductionist approach. We view this as the beginning of a new era,
that of the integration of learning.

Membrane Receptors, Channels and Transporters in Pulmonary Circulation is a proceeding of the 2008 Grover Conference (Lost Valley Ranch and Conference Center, Sedalia, Colorado; September 3-7, 2008), which provided a forum for experts in the fields of those receptors, channels and transporters that have been identified as playing key roles in the physiology and pathophysiology of the pulmonary circulation. The book rigorously addresses: i) recent advances in our knowledge of receptors, channels and transporters and their role in regulation of pulmonary vascular function; ii) how modulation of expression and function of receptors, channels and transporters and their interrelationships contribute to the pathogenesis of pulmonary vascular disease; and iii) the therapeutic opportunities that may be revealed by enhancing our understanding of this area. The overall goal was to explore the mechanisms by which specific receptors, channels and transporters contribute to pulmonary vascular function in both health and disease, and how this knowledge may lead to novel interventions in lung dysplasia, pulmonary edema, lung injury, and pulmonary and systemic hypertension to reduce and prevent death from lung disease. Membrane Receptors, Channels and Transporters in Pulmonary Circulation is divided into six parts. Part 1 (Ion Channels in the Pulmonary Vasculature: Basics and New Findings) is designated for basic knowledge and recent findings in the research field of ion channels in pulmonary circulation. There are five chapters in Part I discussing the function, expression, distribution and regulation of various ion channels present in pulmonary vascular smooth muscle cells and how these channels are integrated to regulate intracellular Ca2+ and cell functions. Part II (TRP Channels in the Pulmonary Vasculature: Basics and New Findings) is composed of five chapters that are exclusively designed to discuss the role of a recently identified family of cation channels, transient receptor potential (TRP) channels, in the regulation of pulmonary vascular tone and arterial structure. Part III (Pathogenic Role of Ion Channels in Pulmonary Vascular Disease) includes four chapters that discuss how abnormal function and expression of various ion channels contribute to changes in cell functions and the development of pulmonary hypertension. Part IV (Receptors and Signaling Cascades in Pulmonary Arterial Hypertension) consists of five chapters devoted to the role of bone morphogenetic protein receptors, Notch receptors, serotonin receptors, Rho kinase and vascular endothelial growth factor receptors in the development of pulmonary arterial hypertension. Part V (Receptors and Transporters: Role in Cell Function and Hypoxic Pulmonary Vasoconstriction) includes four chapters designed to illustrate the potential mechanisms involved in oxygen sensing and hypoxia-induced pulmonary vasoconstriction and hypertension. Part VI (Targeting Ion Channels and Membrane Receptors in Developing Novel Therapeutic Approaches for Pulmonary Vascular Disease) consists five chapters which discuss the translational research involving on membrane receptors, channels and transporters, including their potential as novel drug targets. We hope that Membrane Receptors, Channels and Transporters in Pulmonary Circulation will allow readers to foster new concepts and new collaborations and cooperations among investigators so as to further understand the role of receptors, channels and transporters in lung pathophysiology. The ultimate goal is to identify new mechanisms of disease, as well as new therapeutic targets for pulmonary vascular diseases. An additional outcome should be enhanced understanding of the role of these entities in systemic vascular pathophysiology, since the conference will include researchers and clinicians with interests in both pulmonary and systemic circulations.
Cancer is an incredibly diverse and difficult disease to treat, and even after decades of research there is no definitive cure. Therefore, it is highly crucial to search for novel and new organic molecules with high potency, low toxicity, and low mutagenicity with selective anticancer properties that are able to overcome frequently developed resistance to available drugs. Heterocyclic anticancer agents are an important class of drugs for cancer therapies. This book explores different heterocycles and their use as anticancer therapies. Topics covered include different heterocyclic derivatives, the impact of heterocycles on anticancer agent development, and naturally occurring heterocycles.
It is argued that a critical approach to health studies with an eye of social sciences, particularly benefited from the fields of economics, law, and politics, contributes to the literature on health studies. This edited book comprises seven parts which contain chapters on the field of health studies from the perspectives of economics, law, and politics in Turkey. In this said framework, chapters are organized under seven thematic parts as "economic and public policy perspective in the health sector", "the impact of Europeanization in health law and policy", "gender in health policies and law", "legal and public policy perspective to vaccination application", "reflections of covid-19 in law and economics", "current thematic discussions in health studies", and "noticeable issues in health law". The book contributes to the literature by illustrating discussions and cases from Turkey.
This is the first of a 4-volume module that is an introduction to
the study of cell chemistry and physiology. It is not intended to
be encyclopedic in nature but rather a general survey of the
subject with an emphasis on those topics that are central to an
understanding of cell biology and those that are certain to become
of increasing importance in the teaching of modern medicine.
Physical oncology has the potential to revolutionize cancer research and treatment. The fundamental rationale behind this approach is that physical processes, such as transport mechanisms for drug molecules within tissue and forces exchanged by cancer cells with tissue, may play an equally important role as biological processes in influencing progression and treatment outcome. This book introduces the emerging field of physical oncology to a general audience, with a focus on recent breakthroughs that help in the design and discovery of more effective cancer treatments. It describes how novel mathematical models of physical transport processes incorporate patient tissue and imaging data routinely produced in the clinic to predict the efficacy of many cancer treatment approaches, including chemotherapy and radiation therapy. By helping to identify which therapies would be most beneficial for an individual patient, and quantifying their effects prior to actual implementation in the clinic, physical oncology allows doctors to design treatment regimens customized to each patient's clinical needs, significantly altering the current clinical approach to cancer treatment and improving the outcomes for patients. |
