  • Physiology plays a major role in the scientific foundation of medicine and other subjects related to human health and physical performance. Pharmacology is the science which deals with the effects of drugs on living systems and their use in the treatment of disease. This book is designed to enhance students’ understanding of physiology and pharmacology via a series of case studies involving human disease and its treatment. Traditional university teaching methods focus on informing students in terms of physiological and pharmacological theory.

  • The field of molecular biophysics is introduced in the following pages. The presentation focuses on the simple underlying concepts and demonstrates them using a series of up to date applications. It is hoped that the approach will appeal to physical scientists who are confronted with biological questions for the first time as they become involved in the current biotechnological revolution. The field of biochemistry is vast and it is not the aim of this textbook to encompass the whole area.

  • We live in the age of biology—the human and many other organisms’ genomes have been sequenced and we are starting to understand the function of the metabolic machinery responsible for life on our planet. Thousands of new genes have been discovered, many of these coding for enzymes of yet unknown function. Understanding the kinetic behavior of an enzyme provides clues to its possible physiological role. From a biotechnological point of view, knowledge of the catalytic properties of an enzyme is required for the design of immobilized enzyme-based industrial processes.

  • Plant response to reduced water availability and other abiotic stress (e.g. metals) have been analysed through changes in water absorption and transport mechanisms and also by molecular and genetic approach. A relatively new aspects of fruit nutrition are presented in order to provide the basis for the improvement of some fruit quality traits. The involvement of hormones, nutritional and proteomic plant profiles together with some structure/function of sexual components have also been addressed.

  • A wealth of information has accumulated on the subject of hypertension, and the number of publications dedicated to topics in this field of study continues to increase. It has become nearly impossible for medical professionals to absorb all of the diverse information and to gather the information into a coherent theoretical concept and practical approach to treating the disease, even for those of us who are actively involved in this research specialty on a daily basis.

  • The stomach is located in the epigastrium and the main physiological function of stomach is reservoir of food and drink, then food and drink are fermenting and grinding by action of the stomach so disturbance of these functions of the stomach will cause poor appetite, capacity for only small amount of food, and pain in the epigastric region. Of course, only in cooperation with the spleen's function digesting and transforming food and drink can be performed successfully by the stomach's function of receiving, to receive, digest and transform the food and drink.

  • This compact and concise monograph lays a foundation for the understanding of normal cardiovascular function. Students welcome the book as a practical partner or alternative to a more mechanistically oriented approach or an encyclopedic physiology text. Especially clear explanations, ample illustrations, clinical cases and problems, and chapter-opening learning objectives provide guidance for self-directed learning and help fill the gap in many of today's abbreviated physiology blocks. A focus on well-established cardiovascular principles reflects recent, widely accepted research....

  • The advances in ultra-large-scale integration (ULSI) technology mainly have been based on downscaling of the minimum feature size of complementary metal-oxide semiconductor (CMOS) transistors. The limit of scaling is approaching and there are unsolved problems such as the number of electrons in the device’s active region. If this number is reduced to less than 10 electrons (or holes), quantum fluctuation errors will occur and the gate insulator thickness will become too small to block quantum mechanical tunneling, which may result in unacceptably large leakage currents....

  • SECTION I ECOLOGY OF INDIVIDUAL INSECTS THE INDIVIDUAL ORGANISM IS A FUNDAMENTAL unit of ecology. Organisms interact with their environment and affect ecosystem processes largely through their cumulative physiological and behavioral responses to environmental variation. Individual success in finding and using necessary habitats and resources to gain reproductive advantage determines fitness.

  • The goal of this book is to show how usability metrics can be a powerful tool for successfully evaluating the user experience for any product. When some people think about usability metrics, they feel overwhelmed by complicated formulas, contradictory research, and advanced statistical methods. We hope to demystify much of the research and focus on the practical application of usability metrics. We’ll walk you through a step-by-step approach to collecting, analyzing, and presenting usability metrics.

  • This edited volume contains a selection of chapters that are an outgrowth of the European Conference on Mathematical and Theoretical Biology (ECMTB05, Dresden, Germany, July 2005). The peer-reviewed contributions show that mathematical and computational approaches are absolutely essential for solving central problems in the life sciences, ranging from the organizational level of individual cells to the dynamics of whole populations.

  • In food matrices, bioactivity of polyphenols like all dietary antioxidants in the human body, depends firstly on their bioaccessibility (i.e. the release from the food matrix) and bioavailability (i.e. absorbable fraction that can be used for specific physiological functions in organs). Polyphenols of comparatively high bioavailability include isoflavonids (absorption cover 50%, Bohn, 2010), while e.g. anthocyanins are of very low bioavailability, usually ca. 1.7% (Sakakibara et al., 2009). The prerequisite for bioavailability of any compound is its bioaccessibility in the gut.

  • While it has been demonstrated that these materials have good sensitivity to polar VOCs, such as alcohols and acetone, 11,12 their rather poor response to nonpolar analytes has been viewed as a major drawback. In this report, we explored two ways to improve the sensor performance of regioregular polythiophene. The first approach is to add a second polymer at the end of the polythiophene chain to form a block copolymer. This second polymer interacts with the analytes in different ways, thus adding another dimensionality to the sensing response of the material.

  • Forty years ago there was hardly a field called ‘behavioral sciences’. In fact, psychology largely was the behavioral sciences, with some help from group theory in sociology and decision- making in economics. Now, of course, psychology has expanded and developed in a myriad of ways, to the point where ‘behavioral sciences’ is often the more useful term. Physiological psychology has become neuroscience, covering areas not previously part of psychology. Decision-making has become decision science, involving people from economics, marketing, and other disciplines.

  • The spirit of the DIT community of academic and non-academic members of staff is something which defines the Institute and has been key to its successful development throughout its history. Circa 2,500 people are employed in DIT in many different roles. Although currently dispersed across so many locations around the city, there has been a concerted effort to develop a ‘One DIT’ approach to delivery of teaching and support to students.

  • A major physiological adaptation of the camel is its ability to allow its body temperature to fluctuate. The normal diurnal variation in a fully hydrated camel does not exceed 2°C and is in the range of about 36 to 38°C. In a 500 kg animal the heat stored as a result of diurnal variation of this order would be about 4.2 x 106 (joules). In dehydrated camels, when considerations of energy and water conservation become more important, temperature variation can be as much as 8°C in the range of 34 to 42°C, but a more normal range is 6°C...

This will be both expensive and time-consuming; however, at least in selected cases (e.g., cases of aging and dementia with brain atrophy), such an interaction will be essential. More speculative will be the use of MRI to further constrain PET data by defining gray-white matter differences.
