Unstable angina, myocardial infarction and stroke, precipitated by thrombosis, are the leading causes of death in the western world. In response to such vascular trauma, platelets rapidly adhere to the exposed subendothelial matrix. Platelet activation through agonist and adhesion receptors leads to a cascade of intracellular events including cytoskeletal reorganization and secretion of platelet dense bodies, ultimately resulting in platelet aggregation.;This text aims to highlight the key areas of platelet function in the regulation of haemostasis and thrombosis. The volume covers areas such as platelet production, interaction of platelets with leukocytes, and mechanisms of cross-talk between platelets, leukocytes, and endothelium. The two major clinical causes of thrombosis, anti-phospholipid antibodies and genetic predisposition, are also addressed.
Asthma is a chronic relapsing airways disease that represents a major public health problem worldwide. Intermittent exacerbations are provoked by airway mucosal exposure to pro-inflammatory stimuli, with RNA viral infections or inhaled allergens representing the two most common precipitants. In this setting, inducible signaling pathways the airway mucosa play a central role in the initiation of airway inflammation through production of antimicrobial peptides (defensins), cytokines, chemokines and arachidonic acid metabolites that coordinate the complex processes of vascular permeability, cellular recruitment, mucous hyper-secretion, bronchial constriction and tissue remodeling. These signals also are responsible for leukocytic infiltration into the submucosa, T helper-lymphocyte skewing, and allergic sensitization. Currently, it is well appreciated that asthma is a heterogeneous in terms of onset, exacerbants, severity, and treatment response. Current asthma classification methods are largely descriptive and focus on a single aspect or dimension of the disease. An active area of investigation on how to collect, use and visualize multidimensional profiling in asthma. This book will overview multidimensional profiling strategies and visualization approaches for phenotyping asthma. As an outcome, this work will facilitate the understanding of disease etiology, prognosis and/or therapeutic intervention. "
Proper nutrition is the single most important component of preventative health care. Heart disease, diabetes, and other ailments are all linked to dietary habits. Accurate nutritional assessment can be a matter of life or death.
The French physiologist Claude Bernard was responisble for investigating the chemical phenomena of digestion. This text reproduces his research into experimental medicine. A new introduction looks at his impact on the world of medicine.
This text begins with an in-depth overview into the human organism at the molecular, cellular, tissue and organ levels, and develops into a discussion of the objectives and features of organ systems of the evolved human. The book also covers the relationship between the human body and the environment in which it exists including other organisms that co-habitate the environment. Discussions of the nature of other organisms such as various animals, plants, and micro-organisms makes later information about food science, nutrient density in various food sources, and nutraceuticals easier to comprehend.
The human pancreas consists of two organs in one: the exocrine gland made up of pancreatic acinar cells and duct cells that produce digestive enzymes and sodium bicarbonate, respectively; the endocrine gland made up of four islet cells, namely alpha-, beta-, delta- and PP-cells that produce glucagon, insulin, somatostatin and pancreatic polypeptide, respectively. While the physiological role of exocrine p- creas is to secrete digestive enzyme responsible for our normal digestion, absorption and assimilation of nutrients, the endocrine pancreas is to secrete islet peptide h- mones maintaining our glucose homeostasis. The pancreatic functions are nely regulated by neurocrine, endocrine, paracrine and/or intracrine mechanisms. Thus, dysregulation of these pathways should have signi cant impacts on our health and disease. Nevertheless, the underlying mechanisms by which pancreatic functions are regulated remain poorly understood. Recent basic science and clinical studies con rm myriad physiological and pathophysiological roles of the tissue renin-angiotensin systems (RAS). Of parti- lar interest is the recent identi cation of a local and functional RAS in the pancreas, which in uences both its exocrine and endocrine function. Its role in the pat- genesis of pancreatic diseases including diabetes and pancreatitis is increasingly recognized, as is the therapeutic potential of RAS antagonism: RAS blockade l- its disease progression of type 2 diabetes mellitus and impaired glucose tolerance, and may also protect against pancreatic in ammation.
A rapid development in diverse areas of molecular biology and genetic engineering resulted in emergence of variety of tools. These tools are not only applicable to basic researches being carried out world over, but also exploited for precise detection of abnormal conditions in plants, animals and human body. Although a basic researcher is well versed with few techniques used by him/her in the laboratory, they may not be well acquainted with methodologies, which can be used to work out some of their own research problems. The picture is more blurred when the molecular diagnostic tools are to be used by physicians, scientists and technicians working in diagnostic laboratories in hospitals, industry and academic institutions. Since many of them are not trained in basics of these methods, they come across several gray areas in understanding of these tools. The accurate application of molecular diagnostic tools demands in depth understanding of the methodology for precise detection of the abnormal condition of living body. To meet the requirements of a good book on molecular diagnostics of students, physicians, scientists working in agricultural, veterinary, medical and pharmaceutical sciences, it needs to expose the reader lucidly to: Give basic science behind commonly used tools in diagnostics Expose the readers to detailed applications of these tools and Make them aware the availability of such diagnostic tools The book will attract additional audience of pathologists, medical microbiologists, pharmaceutical sciences, agricultural scientists and veterinary doctors if the following topics are incorporated at appropriate places in Unit II or separately as a part of Unit-III in the book. Molecular diagnosis of diseases in agricultural crops Molecular diagnosis of veterinary diseases. Molecular epidemiology, which helps to differentiate various epidemic strains and sources of disease outbreaks. Even in different units of the same hospital, the infections could be by different strains of the same species and the information becomes valuable for infection control strategies. Drug resistance is a growing problem for bacterial, fungal and parasitic microbes and the molecular biology tools can help to detect the drug resistance genes without the cultivation and in vitro sensitivity testing. Molecular diagnostics offers faster help in the selection of the proper antibiotic for the treatment of tuberculosis, which is a major problem of the in the developing world. The conventional culture and drug sensitivity testing of tuberculosis bacilli is laborious and time consuming, whereas molecular diagnosis offers rapid drug resistant gene detection even from direct clinical samples. The same approach for HIV, malaria and many more diseases needs to be considered. Molecular diagnostics in the detection of diseases during foetal life is an upcoming area in the foetal medicine in case of genetic abnormalities and infectious like TORCH complex etc. The book will be equally useful to students, scientists and professionals working in the field of molecular diagnostics.

The transplantation of organs such as the heart, kidney, and lungs is an important means of replacing seriously damaged or diseased body parts. However, a transplanted organ may fail if the recipient's immune system mounts a response to it. Transplant patients are usually prescribed a life-long course of immunosuppressive medication, but these drugs can have adverse effects, including increased risk of infection and cancer. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine provides a current and comprehensive review of the molecular mechanisms behind graft rejection and how they may be overcome. Contributors discuss immunosuppressive drug therapies and tolerance induction strategies, including the use of regulatory T cells, mesenchymal stromal cells, and lymphodepletion. They describe how mouse and non-human primate models have been used to gain insight into the immunobiology of transplantation and to test therapeutic approaches. Clinical considerations, such as donor selection, organ preservation, surgery, and post-operative care, are also covered. This volume includes discussion of the emerging field of regenerative medicine and the bioethical issues surrounding organ transplantation, and provides historical background to the field. It is an essential reference for immunologists, pharmacologists, clinicians, and all who are working to improve this remarkable medical procedure.

Measurement of Cardiac Function presents detailed descriptions of how to set up and use several classical cardiac preparations from scratch. The preparations include whole heart, atrial, ventricular, and papillary muscles and in vivo small animal preparations. Methods for monitoring contraction and contractility are fully described. Flow charts and step-by-step instructions make it easy to understand, even for the first time investigator.
This book summarizes present knowledge of different mechanisms involved in the development of positive and negative consequences of cardiac adaptation. Particular attention is paid to the still underestimated adaptive cardiac responses during development, to adaptation to the frequently occurring pressure and volume overload as well as to cardiac changes, induced by enduring exercise and chronic hypoxia. "Cardiac Adaptations" will be of great value to cardiovascular investigators, who will find this book highly useful in their cardiovascular studies for finding solutions in diverse pathological conditions; it will also appeal to students, fellows, scientists, and clinicians interested in cardiovascular abnormalities."
The rapidly evolving field of protein science has now come to realize the ubiquity and importance of protein-protein interactions. It had been known for some time that proteins may interact with each other to form functional complexes, but it was thought to be the property of only a handful of key proteins. However, with the advent of high throughput proteomics to monitor protein-protein interactions at an organism level, we can now safely state that protein-protein interactions are the norm and not the exception. Thus, protein function must be understood in the larger context of the various binding complexes that each protein may form with interacting partners at a given time in the life cycle of a cell. Proteins are now seen as forming sophisticated interaction networks subject to remarkable regulation. The study of these interaction networks and regulatory mechanism, which I would like to term "systems proteomics," is one of the thriving fields of proteomics. The bird-eye view that systems proteomics offers should not however mask the fact that proteins are each characterized by a unique set of physical and chemical properties. In other words, no protein looks and behaves like another. This complicates enormously the design of high-throughput proteomics methods. Unlike genes, which, by and large, display similar physico-chemical behaviors and thus can be easily used in a high throughput mode, proteins are not easily amenable to the same treatment. It is thus important to remind researchers active in the proteomics field the fundamental basis of protein chemistry. This book attempts to bridge the two extreme ends of protein science: on one end, systems proteomics, whichdescribes, at a system level, the intricate connection network that proteins form in a cell, and on the other end, protein chemistry and biophysics, which describe the molecular properties of individual proteins and the structural and thermodynamic basis of their interactions within the network. Bridging the two ends of the spectrum is bioinformatics and computational chemistry. Large data sets created by systems proteomics need to be mined for meaningful information, methods need to be designed and implemented to improve experimental designs, extract signal over noise, and reject artifacts, and predictive methods need to be worked out and put to the test. Computational chemistry faces similar challenges. The prediction of binding thermodynamics of protein-protein interaction is still in its infancy. Proteins are large objects, and simplifying assumptions and shortcuts still need to be applied to make simulations manageable, and this despite exponential progress in computer technology. Finally, the study of proteins impacts directly on human health. It is an obvious statement to say that, for decades, enzymes, receptors, and key regulator proteins have been targeted for drug discovery. However, a recent and exciting development is the exploitation of our knowledge of protein-protein interaction for the design of new pharmaceuticals. This presents particular challenges because protein-protein interfaces are generally shallow and interactions are weak. However, progress is clearly being made and the book seeks to provide examples of successes in this area.
This volume, based on the International Congress Creatine: From Basic Science to Clinical Application, held in Milan on June 4, 1999, outlines the physiological role of creatine in the human body as well as its possible role in different pathological conditions. Creatine is already used as a dietary supplement to augment muscle performance in healthy individuals and inpatients with immobilizing diseases, such as complex fractures. There is also an increasing interest in its administration in a growing number of clinical conditions. A specific deficit of endogenous synthesis of creatine which responds to high dosage exogenous supplementation has been described. In cardiac failure and in chronic obstructive pulmonary disease, creatine improves the contractility of the muscular system. Promising effects of this substance have also been described in animal models of neurodegenerative disorders, such as amyotrophic lateral sclerosis, and in some mitochondrial cytopathies. This volume is of obvious interest to basic scientists working on the physiology of creatine and to clinicians interested in its medical indications.

There's a silent epidemic in western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Modern orthodontics has persuaded us that braces and oral devices can correct these problems. While teeth can certainly be straightened, what about the underlying causes of this rapid shift in oral evolution and the health risks posed by obstructed airways? Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis, as well as a major alternative to orthodontics that promises more significant long-term relief. Jaws will change your life. Every parent should read this book.
