This is the story of a race - not against other vaccines or other scientists, but against a deadly and devastating virus. On 1 January 2020, Sarah Gilbert, Professor of Vaccinology at Oxford University, read an article about four people in China with a strange pneumonia. Within two weeks, she and her team had designed a vaccine against a pathogen that no one had ever seen before. Less than 12 months later, vaccination was rolled out across the world to save millions of lives from Covid-19. In Vaxxers, we hear directly from Professor Gilbert and her colleague Dr Catherine Green as they reveal the inside story of making the Oxford AstraZeneca vaccine and the cutting-edge science and sheer hard work behind it. This is their story of fighting a pandemic as ordinary people in extraordinary circumstances. Sarah and Cath share the heart-stopping moments in the eye of the storm; they separate fact from fiction; they explain how they made a highly effective vaccine in record time with the eyes of the world watching; and they give us hope for the future. Vaxxers invites us into the lab to find out how science will save us from this pandemic, and how we can prepare for the inevitable next one.
Levels of mycotoxin contamination in agricultural commodities are
regulated in more than 100 countries, and exposure to these
naturally occurring toxins presents serious risks to the health of
humans and animals with negative impacts to commodity values. This
symposium series book presents significant scientific developments
in the multifaceted approach to reducing exposure to these
naturally occurring toxins. A broad-spectrum of subject matter of
the multidisciplinary field of mycotoxin research is conveniently
compiled in this single volume, and general themes include
prevention, control, exposure, molecular biology, biosynthesis,
analytical methodology, and emerging techniques. The book opens
with an overview of prevention of mycotoxin production by means of
biological control and human exposure to contaminated foods,
including tofu, apples, figs, and a broad range of fruits.

Bioinspiration is recognized by the World Health Organization as having great promise in transforming and democratizing health systems while improving the quality, safety, and efficiency of standard healthcare in order to offer patients the tremendous opportunity to take charge of their own health. This phenomenon can enable great medical breakthroughs by helping healthcare providers improve patient care, make accurate diagnoses, optimize treatment protocols, and more. Unfortunately, the consequences can be serious if those who finance, design, regulate, or use artificial intelligence (AI) technologies for health do not prioritize ethical principles and obligations in terms of human rights and preservation of the private life. Advanced Bioinspiration Methods for Healthcare Standards, Policies, and Reform is the fruit of the fusion of AI and medicine, which brings together the latest empirical research findings in the areas of AI, bioinspiration, law, ethics, and medicine. It assists professionals in optimizing the potential benefits of AI models and bioinspired algorithms in health issues while mitigating potential dangers by examining the complex issues and innovative solutions that are linked to healthcare standards, policies, and reform. Covering topics such as genetic algorithms, health surveillance cameras, and hybrid classification algorithms, this premier reference source is an excellent resource for AI specialists, hospital administrators, health professionals, healthcare scientists, students and educators of higher education, government officials, researchers, and academicians.
Biology: A Historical Perspective Volume I introduces students to key concepts of the science curriculum and the scientists responsible for the significant discoveries and developments within the discipline. The text also provides readers with a unique historical perspective into the accomplishments of often underrepresented scientists such as Jean Vance, Friedrich Miescher, Walther Flemming, and Edith Rebecca Saunders, among others. Each chapter begins with a brief biographical sketch of a scientist who helped shape the current understanding of a particular scientific concept. The opening chapter introduces science and its main components, including the scientific method. It also defines biology and presents the scientists who were instrumental in classifying life. Additional chapters explore the basic concepts of chemistry, macromolecules, cells, metabolism, and energy flow between organisms. Students learn about the structure of DNA and chromosomes, the cell cycle, theories regarding inheritance, the fixity of species, the Hardy-Weinberg principle, evolution, and more. Biology is the first textbook in a two-volume series that celebrates the scientists behind significant findings and principles. It is ideal for foundational courses in biology.
Moving away from the long-established paradigm which holds that all political behavior is learned via socialization, this Handbook assesses the contributions of biology to political science, illustrating that behavior is in actual fact shaped by the interplay between learning and biological influences. Describing how a more biologically-oriented approach expands and enriches political science, both conceptually and in terms of its research capabilities, key chapters focus on general biological approaches to politics, biopolitical contributions to mainstream areas within political science, and linkages between biology and public policy. Providing specific examples of how Neo-Darwinism can contribute to more successful public policies, the Handbook further emphasizes the close ties between a realistic understanding of human political behavior and the likelihood that our species successfully resolves the problems that now threaten its welfare. Original and thought-provoking, this Handbook will prove an enriching read for political scientists starting to consider the value of biological factors in influencing political behavior, as well as for behavioural scientists in other areas experiencing the same paradigm shifts. Biologists will also find further grounding for their research into biological and behavioral science. Contributors include: K.Blanchard, Jr., R.H. Blank, D. Boisvert, E. Bucy, K. Butts, P.A.

The lymphatic system develops and functions in parallel with the blood circulatory system (termed the "hemovasculature") and accomplishes transport of interstitial fluids, dietary lipids, and reverse transport of cholesterol, immune cells, and antigens-providing a critical homeostatic fluid balance and transmission of immune cells and mediators back to the cardiovascular system. Although the daily flow of lymph (normally 1-2 L/day under unstressed conditions) is far lower than that of daily blood flow (which is 7,500 L/day), without the adequate functioning of the lymphatics, virtually all organs and tissues would acutely suffer many different physical and inflammatory stresses ranging from edema to organ system failure. Although blood and lymphatic vessels often form in anatomic parallels to one another, our knowledge of the workings of the lymphatic system, the fine structure of lymphatic networks, how they function in different organs, and how they are regulated physiologically and immunologically are far from parallel; our knowledge of the lymphatic system still remains at only a tiny fraction of what is understood about the cardiovascular system. Although both the cardiovascular and lymphatic systems are important transport systems, what they transport and how they transport and propel these very different cargoes could not be more dissimilar. This book provides an overview of the history of the discovery (and re-discovery) of the components of the lymphatic system, lymphatic anatomy, physiological functions of lymphatics, molecular features of the lymphatic system, and clinical perspectives involving lymphatics which may be of interest to scientists, clinicians, patients, and the lay public. We provide a current understanding of some of the more important structural similarities and differences between lymphatics and the blood vascular system, their coordinated control by angiogenic and hemangiogenic growth factors and other modulators, the fate and lineage determinants which control lymphatic development, and the roles that lymphatics may play in several different diseases.
This collaboration of two physiologists and a gastroenterologist provides medical and graduate students, medical and surgical residents, and subspecialty fellows a comprehensive summary of digestive system physiology and addresses the pathophysiological processes that underlie some GI diseases. The textual approach proceeds by organ instead of the traditional organization followed by other GI textbooks. This approach lets the reader track the food bolus as it courses through the GI tract, learning on the way each organ's physiologic functions as the bolus directly or indirectly contacts it. The book is divided into three parts: (1) Chapters 1-3 include coverage of basic concepts that pertain to all (or most) organs of the digestive system, salivation, chewing, swallowing, and esophageal function, (2) Chapters 4-6 are focused on the major secretory organs (stomach, pancreas, liver) that assist in the assimilation of a meal, and (3) Chapters 7 and 8 address the motor, transport, and digestive functions of the small and large intestines. Each chapter includes its own pathophysiology and clinical correlation section that underscores the importance of the organ's normal function.
Clathrin-mediated endocytosis (CME) is a ubiquitous internalization process in eukaryotic cells. It consists of the formation of an approximately 50-nm diameter vesicle out of a flat membrane. Genetics, biochemistry, and microscopy experiments performed in the last four decades have been instrumental to discover and characterize major endocytic proteins in yeast and mammals. However, due to the highly dynamic nature of the endocytic assembly and its small size, many questions remain unresolved: how are endocytic proteins organized spatially and dynamically? How are forces produced and how are their directions controlled? How do the biochemical activities of endocytic proteins and the membrane shape and mechanics regulate each other? These questions are virtually impossible to visualize or measure directly with conventional approaches but thanks to new quantitative biology methods, it is now possible to infer the mechanisms of endocytosis in exquisite detail. This book introduces quantitative microscopy and mathematical modeling approaches that have been used to count the copy number of endocytic proteins, infer their localization with nanometer precision, and infer molecular and physical mechanisms that are involved in the robust formation of endocytic vesicles.
Environmental heat stress is associated with a marked decrease in orthostatic tolerance (OT), which is defined as the ability to stand or sit upright without symptoms of dizziness, lightheadedness, presyncope, or fainting. In most healthy humans, the autonomic nervous system makes rapid and balanced adjustments to heart rate and peripheral blood flow, such that most people are able to stand up "successfully" most of the time, in most environments. The goal of this book is to discuss various aspects of the sympathetic neural response to heat stress, how the sympathetic nervous system coordinates the successful integrative physiological response to orthostasis, and what happens when it encounters both challenges simultaneously. We include overviews of mechanisms of thermoregulation and blood pressure regulation in humans, with particular focus on control of cardiac output and neurovascular control mechanisms during heat stress. We discuss the implications that these changes have for distribution of peripheral blood flow and, in particular, for blood flow to the cerebral circulation. The added stressor of dehydration is also discussed, as it so often goes hand in hand with heat stress. We end with a brief presentation of countermeasures against the decreases in OT with heat stress.
The kidney is innervated with efferent sympathetic nerve fibers reaching the renal vasculature, the tubules, the juxtaglomerular granular cells, and the renal pelvic wall. The renal sensory nerves are mainly found in the renal pelvic wall. Increases in efferent renal sympathetic nerve activity reduce renal blood flow and urinary sodium excretion by activation of 1-adrenoceptors and increase renin secretion rate by activation of 1-adrenoceptors. In response to normal physiological stimulation, changes in efferent renal sympathetic nerve activity contribute importantly to homeostatic regulation of sodium and water balance. The renal mechanosensory nerves are activated by stretch of the renal pelvic tissue produced by increases in renal pelvic tissue of a magnitude that may occur during increased urine flow rate. Under normal conditions, the renal mechanosensory nerves activated by stretch of the sensory nerves elicits an inhibitory renorenal reflex response consisting of decreases in efferent renal sympathetic nerve activity leading to natriuresis. Increasing efferent sympathetic nerve activity increases afferent renal nerve activity which, in turn, decreases efferent renal sympathetic nerve activity by activation of the renorenal reflexes. Thus, activation of the afferent renal nerves buffers changes in efferent renal sympathetic nerve activity in the overall goal of maintaining sodium balance. In pathological conditions of sodium retention, impairment of the inhibitory renorenal reflexes contributes to an inappropriately increased efferent renal sympathetic nerve activity in the presence of sodium retention. In states of renal disease or injury, there is a shift from inhibitory to excitatory reflexes originating in the kidney. Studies in essential hypertensive patients have shown that renal denervation results in long-term reduction in arterial pressure, suggesting an important role for the efferent and afferent renal nerves in hypertension.
