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.
The second section focuses on molecular biological approaches to
control mycotoxin exposure. Topics covered include genomic
approaches, detoxification, structure-activity studies of
biosynthetic precursors, and mycotoxin biosynthesis. The success of
these strategies is supported by the reduction of mycotoxin
occurrence and incidence in foods. Accurate estimates of mycotoxin
concentration in foods are important for food safety and
wholesomeness.
The final section covers analytical approaches, including sampling
plans for foods and dietary supplements, extraction efficiency of
mycotoxins from naturally contaminated grains, traditional
detection methods such as chromatography/mass spectrometry, and
emerging techniques such as the use of molecularly imprinted
polymers for purification and isolation and cyclodextrins for
fluorescent enhancement of several mycotoxins.

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.
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

efficient and accurate prediction and characterization of
functional and structural aspects of proteins. It spotlights key
advances which include deep neural networks, natural language
processing-based sequence embedding and covers a wide range of
predictions which comprise of tertiary structure, secondary
structure, residue contacts, intrinsic disorder, protein, peptide
and nucleic acids-binding sites, hotspots, post-translational
modification sites, and protein function. This volume is loaded
with practical information that identifies and describes leading
predictive tools, useful databases, webservers, and modern software
platforms for the development of novel predictive tools.
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.
