This book introduces the UTCI (Universal Thermal Climate Index) and summarizes progress in this area. The UTCI was developed as part of the European COST Action Program and first announced to the scientific community in 2009. Since then, a decade has followed of applicability tests and research results, as well as knowledge gained from applying the UTCI in human adaptation and thermal perception. These findings are of interest to researchers in the interdisciplinary areas of biometeorology, climatology and urban planning. The book summarizes this progress, discussing the limitations found and provides pointers to future developments. It also discusses UTCI applications in the areas of human biometeorology and urban planning including possibilities of using UTCI and similar indices in climate-responsive urban planning. The book's message is illustrated with many case studies from the real world. Chapter 10 is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
This book focuses on C-type lectin receptors, a newly emerging family of pattern-recognition receptors (PRRs) and a crucial part of the human innate immune system. Above all, the authors highlight these receptors' role in the recognition of pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) - one of the first steps in responding to foreign and potentially dangerous structures in the human body. The respective chapters chiefly examine various C-type lectin receptors, their corresponding ligands, and signalling. In addition to offering immunologists and clinicians important insights from the latest research, they may also provide novel points of departure for future drug development.
This book focuses on a development for assessing mental changes using eye pupil reactions, namely extracting emotional change from the response to evaluate the viewer's interest in visual information. The pupil of the eye reacts to both brightness and emotional state, including interest, enjoyment, and mental workload. Because pupillary change is a biological signal, various artifacts influence measurements of eye images. Technical procedures are required to extract mental activities from pupillary changes, and they are summarized here step by step, although some procedures contain earlier techniques such as analog video processing. This study examines the possibility of estimating the viewer's interest and enjoyment of viewing movies by measuring the dynamic pupillary changes, blinking, and subjective interest responses. In evaluation of pupil size, there was a significant difference in pupil size between the higher and the lower shot for the degree of subject interest response in each kind of movies. The first part of the book shows a pupil reaction model for brightness changes to extract mental activities. Pupil reactions were observed for various visual stimuli in brightness changes. With regard to the characteristics of pupillary changes, a model with a three-layer neural network was developed and the performance was evaluated. Characteristics of pupil reactions during model development are summarized here. The second part examines the possibility of estimating the viewer's interest and enjoyment of television programs by measuring dynamic pupillary changes, blinking, and subjective interest responses. The final part describes a development of estimation model of pupil size for blink artifact. The model development was able to estimate pupillary changes and pupil size while the viewer was blinking and was applied to pupillary changes in viewing television programs.

Vaccines against antigenically stable pathogens, or pathogens that only exist in a limited number of serotypes, have been very successful in the past and have drastically decreased the incidence and lethality of many diseases. However, when it comes to highly variable pathogens or viruses that exist in multiple serotypes, the traditional methods for vaccine development have reached their limits. This volume highlights the development of vaccines against such challenging pathogens. Novel approaches for immunogen design, including structure-guided vaccine development and vaccines targeting glycans, as well as adjuvants and animal models used for testing possible vaccine candidates are outlined and discussed in detail. Given its scope, the book will appeal to scientists in the fields of infectious diseases, microbiology and medicine.

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.
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.

The face circulates through most things of this world: anything that has presence, that presents itself, that has a front, a surface, an appearance, an aspect, a reputation, or honor - anything that confronts, opposes, or defies - has a face. And the face is a front: from the back it is just a head, a radically different entity. In this exciting new book - and sadly his last before his untimely death - distinguished philosopher Marty Roth pursues considerations of the human face in art, literature, philosophy, and other manifestations of human culture.

An enthralling exploration that upends the prevailing view of consciousness and demonstrates how intelligence is literally embedded in the palms of our hands If you think that intelligence emanates from the mind and that reasoning necessitates the suppression of emotion, you'd better think again-or rather not "think" at all. In his provocative new book, Guy Claxton draws on the latest findings in neuroscience and psychology to reveal how our bodies-long dismissed as mere conveyances-actually constitute the core of our intelligent life. From the endocrinal means by which our organs communicate to the instantaneous decision-making prompted by external phenomena, our bodies are able to perform intelligent computations that we either overlook or wrongly attribute to our brains. Embodied intelligence is one of the most exciting areas in contemporary philosophy and neuropsychology, and Claxton shows how the privilege given to cerebral thinking has taken a toll on modern society, resulting in too much screen time, the diminishment of skilled craftsmanship, and an overvaluing of white-collar over blue-collar labor. Discussing techniques that will help us reconnect with our bodies, Claxton shows how an appreciation of the body's intelligence will enrich all our lives.

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.

The central nervous system, which includes the brain and spinal cord, has a high metabolic demand. The physiology of the brain is such that it is easily affected by alterations in other systems, which in turn can compromise cerebral blood flow and oxygenation. Together the brain and spinal cord control the automatic function of our body systems. While other systems of body controls individual functions, central nervous system at the same time does many different functions, especially, controlling the function of other systems. This interaction between the brain and other systems is important when it comes to understanding how injuries to the brain can, at times, produce complications in remote organs or systems of the body, such as the lungs. This book explains the lesser-known crosstalks between acutely or chronically affected brain and lung, describing the pathophysiology of the lung following brain injury and discussing in detail the conflicts between the brain and lungs in relation to the tidal volumes, positive end-expiratory pressures, arterial carbon dioxide and oxygen levels, recruitment maneuvers and positioning, as well as potential therapeutic targets.
