Bayesian analysis is one of the important tools for statistical modelling and inference. Bayesian frameworks and methods have been successfully applied to solve practical problems in reliability and survival analysis, which have a wide range of real world applications in medical and biological sciences, social and economic sciences, and engineering. In the past few decades, significant developments of Bayesian inference have been made by many researchers, and advancements in computational technology and computer performance has laid the groundwork for new opportunities in Bayesian computation for practitioners. Because these theoretical and technological developments introduce new questions and challenges, and increase the complexity of the Bayesian framework, this book brings together experts engaged in groundbreaking research on Bayesian inference and computation to discuss important issues, with emphasis on applications to reliability and survival analysis. Topics covered are timely and have the potential to influence the interacting worlds of biostatistics, engineering, medical sciences, statistics, and more. The included chapters present current methods, theories, and applications in the diverse area of biostatistical analysis. The volume as a whole serves as reference in driving quality global health research.
The biennial TNF-family conferences have been held over the past 20 years, from the time that TNF was cloned. These meetings have followed the enormous progress in this field. Much is now known about the members of the TNF ligand and receptor families, their signaling proteins, mechanisms of action and cellular functions. This volume is the proceedings of the 12th TNF International Conference, held in April 2009. This conference focuses on the physiological, pathophysiological, and medical significance of these important regulators. Sessions at the meeting specifically address their involvement in immunity, development, apoptosis, autoimmunity, cancer, and infection, the normal function and pathology of the neuronal system, as well as major unresolved questions about their mechanisms of action.

Primary Aldosteronism (PA) is a disease caused by the overproduction of aldosterone hormone from the adrenal glands. PA causes hypertension and the majority with this disease are undiagnosed for PA. There are new insights into this matter by using biochemistry as well as advanced radiology. In 2011, a breakthrough in the genetic derangements came, identifying a mutated potassium channel gene - KCNJ5 - in about 40% of PA with adenoma. Chapters in this book include a history of the disorder, epidemiology, genetics derangements, the KCNJ5 mutations and phenotype and more.
This book offers comprehensive information on the new and rapidly evolving science of identifying and targeting senescent cells, and on the exciting prospect of new diagnostic and therapeutic opportunities for stopping, and even reversing, the progression of disease and the deterioration of the human body due to ageing. According to recent United Nations data, by 2050 one in six people worldwide will be older than age 65, with peaks rising to one in four people in Europe and North America. Remarkably, the number of persons aged 80 years or older is expected to triple, from 143 million in 2019 to 426 million in 2050. First documented in the 1960s, the concept of cellular senescence as an underlying cause of ageing has been established in the course of the last decade. Using genetically engineered mouse models, researchers have demonstrated that the selective elimination of senescent cells can block and even reverse a number of age-related dysfunctions and pathologies, promoting both better health and longer life in the elderly. These include cardiovascular diseases; neurological disorders; type 1 and type 2 diabetes; inflammatory diseases; fibrosis; geriatric syndromes; chronic diseases resulting in organ dysfunction; the integrity of the musculoskeletal system; and cancer. Some senolytic agents have already progressed into trials. These include UBX0101 for the treatment of osteoarthritis (now in phase II), a cocktail of dasatinib and quercetin for the management of idiopathic pulmonary fibrosis and chronic kidney disease, and ABT-263 in combination with senescence-inducing chemotherapies for the treatment of advanced solid tumours. In addition, the book discusses pathways to early phase clinical trials and translational approaches in medicine and ageing, highlighting new opportunities as well as current limitations, challenges and alternatives. Given its scope, it will benefit a broad audience of advanced educators, researchers, graduate students and practitioners.

This book describes recent radiotherapy technologies including tools for measuring target position during radiotherapy and tracking-based delivery systems. This book presents a customized prediction of respiratory motion with clustering from multiple patient interactions. The proposed method contributes to the improvement of patient treatments by considering breathing pattern for the accurate dose calculation in radiotherapy systems. Real-time tumor-tracking, where the prediction of irregularities becomes relevant, has yet to be clinically established. The statistical quantitative modeling for irregular breathing classification, in which commercial respiration traces are retrospectively categorized into several classes based on breathing pattern are discussed as well. The proposed statistical classification may provide clinical advantages to adjust the dose rate before and during the external beam radiotherapy for minimizing the safety margin. In the first chapter following the Introduction to this book, we review three prediction approaches of respiratory motion: model-based methods, model-free heuristic learning algorithms, and hybrid methods. In the following chapter, we present a phantom study-prediction of human motion with distributed body sensors-using a Polhemus Liberty AC magnetic tracker. Next we describe respiratory motion estimation with hybrid implementation of extended Kalman filter. The given method assigns the recurrent neural network the role of the predictor and the extended Kalman filter the role of the corrector. After that, we present customized prediction of respiratory motion with clustering from multiple patient interactions. For the customized prediction, we construct the clustering based on breathing patterns of multiple patients using the feature selection metrics that are composed of a variety of breathing features. We have evaluated the new algorithm by comparing the prediction overshoot and the tracking estimation value. The experimental results of 448 patients' breathing patterns validated the proposed irregular breathing classifier in the last chapter.

Serendipitous discovery has played an important role m the identification of physiological mechanisms in central and peri- eral neurotransmission. In many cases, the subsequent followup of these discoveries has been substantially aided by previouslyiden- fied natural substances that interfered with these mechanisms. The site of neuromuscular blockade produced by curare extracts, for example, was shown in the 1850s by Claude Bernard, and Sir Henry H. Dale m 1906 discovered the reversal of the pressor effects of adrenal extracts by ergot alkaloids. These findings were the first clues that led eventually to the definition of mcotinic cholinergic receptors and the present classification of adrenergic receptors. In the 1950s many discoveries, including the identification of the catecholamines and 5-hydroxytryptamine in the central n- vous system, followed by the development of specific sensitive biochemical and histochemical methods and the introduction of modern psychotropic drugs led to our increased understanding of chemical transmission and the formulation of theories that attempt to explain the causes of some mental disorders. The finding that hydroxylated derivatives of noradrenaline and- hydroxytryptamine are readily taken up by catecholaminergic or serotonergic neurons, and that this is followed by poisoning and death of the cell, encouraged the use of these compounds for the mapping of central and peripheral catecholamine or- hydroxytryptamine systems, and the mvestigation of the re- vance of these pathways to receptor regulation or behavioral - sponses.

Over the past 25 years, biobanks of human specimens have become a cornerstone for research on human health and have empowered the "omics "revolution that characterizes biomedical science in the XXIst Century. Today, biobanking of human specimens is a critical component of the interface between clinical practice and translational research, supporting the discovery and validation of new biomarkers of disease etiology, risk, early detection, diagnosis, prognosis, prediction and relapse. With the development of personalized medicine, biobanking of cryopreserved specimens has become standard practice in order to investigate genetic, transcriptomic, proteomic, metabolomics and immunological biomarkers useful to inform caregivers for therapeutic decisions. Data generated from biobanked specimens represent a rapidly growing and highly valuable resource, participating in the emergence of Big Data Medicine. With the development of large computing capabilities and artificial intelligence, data associated with biobanked specimens constitute a unique resource for the discovery and validation of new biomarkers and therapeutically actionable targets. Interconnecting, interoperating and sharing this data have become major issues for national health systems, raising enormous stakes as well as major societal, legal and cybersecurity challenges in terms of compliance with the protection of personal sensitive information. This book project is the second part of an initiative launched in 2012 to produce a published corpus of knowledge encompassing all aspects of human biobanking as a central practice for research and medicine. The first volume, published in 2017, is entitled: Human Biobanking: Principles and Practice. This first volume compiled a series of high level contributions overseeing the main developments that carried the progression of human biobanking as a research and biotechnological field over the past two decades. This new book project will constitute de facto Volume 2 of the same initiative, under the title: Biobanking of Human Biospecimens: lessons from 25 years of biobanking experience. Hence, the two volumes will share the same generic title (Biobanking of Human Biospecimens), with different subtitles, making clear that the two volumes are interrelated while highlighting their specificities in terms of what they actually cover. As a result, the two books are "twins" but can also be used independently of each other. The overarching aim of the two volumes of Biobanking of Human Biospecimens is to provide a published "one-stop shop" for state-of-the-art information on what constitutes the field of human biobanking, from conception of a biobank, standard operating procedures, ethical and societal aspects, governance, networking, interoperability and economic sustainability. This inclusive publication concept meets the needs of a vast readership, including scientists, doctors and technical staffs who are directly involved in biobanking operations, scientists in other disciplines that heavily rely on biobanking (such as genomics or proteomics), stakeholders and policy makers, and of course students for whom biobanking is becoming an important part of the training curriculum. So far, there has been a lack of major textbooks on biobanking. Documentation for biobanking is widely available through numerous publications, regulatory documents published by International or Governmental Agencies, and sets of recommendations essentially accessible through the Internet. However, it is difficult to access a single, top-of-the shelf reference that provides at a glance a large coverage of all aspects of human biobanking. Fulfilling this need is the main origin of the concept for this back-to-back publication project. To our knowledge, there is currently no other publication project with the same breath and scope as this one in the field of biobanking.
