This book discusses the maximal power and capacity of the three
major biochemical pathways - aerobic (oxygen consumption),
anaerobic lactic (muscle lactate accumulation in absence of oxygen
consumption), and anaerobic alactic (phosphocreatine hydrolysis)
metabolism - as well as the factors that limit them. It also
discusses the metabolic and cardio-pulmonary mechanisms of the
dynamic response to exercise. The way and extent to which the power
and capacity of the three major energy metabolisms are affected
under a number of different conditions, such as training, hypoxia
and microgravity, are also described.
As discussed in this book, a large body of evidence indicates that
selenium is a cancer chemopreventive agent. Further evidence points
to a role of this element in reducing viral expression, in
preventing heart disease, and other cardiovascular and muscle
disorders, and in delaying the progression of AIDS in HIV infected
patients. Selenium may also have a role in mammalian development,
in male fertility, in immune function and in slowing the aging
process. The mechanism by which selenium exerts its beneficial
effects on health may be through selenium-containing proteins.
Selenium is incorporated into protein as the amino acid
selenocysteine. Selenocysteine utilizes a specific tRNA, a specific
elongation factor, a specific set of signals, and the codeword,
UGA, for its cotranslational insertion into protein. It is indeed
the 21st naturally occurring amino acid to be incorporated into
protein and marks the first and only expansion of the genetic code
since the code was deciphered in the mid 1960s.
The role of oxidative stress in human disease has become an area of
intense interest. Free radicals, a normal product of metabolism,
exist in all aerobic cells in balance with biochemical
antioxidants. Environmental stress increases the levels of free
radicals drastically, thereby disturbing the equilibrium between
free radical production and the antioxidant capability causing
oxidative stress. Over the years, ROS has been implicated in the
pathologies of various diseases like cancer, neurological disorder,
cardiovascular diseases rheumatoid arthritis, diabetes etc. This
book provides an in depth critical state-of-art reviews from
established investigators on free radicals, ROS associated
pathogenesis of human diseases, biomarkers of oxidative damage,
antioxidants, phytonutrients and other related health concerns of
modern society. The present book is aimed at graduate students,
researchers in academia, industry and clinicians with the interest
in redox biology. Special attention has been devoted to the topic
of ROS signalling, oxidative stress induced human pathologies &
antioxidative therapies. The book consists of four parts in
specified topics based on the current literatures for the better
understanding of the readers with respect to their subject-wise
interests. The first section of the book provides an overview about
the ROS production and their measuring tools and techniques
followed by the mechanisms involved in the oxidative stress in the
second section. The third section describes the involvement of
oxidative stress in different human diseases and the last section
focuses on the different strategies to ameliorate oxidative stress
induced stress.
Exploring behaviour through bones has always been a fascinating
topic to those that study human remains. Human bodies record and
store vast amounts of information about the way we move, where we
live, and our experiences of health and socioeconomic
circumstances. We see it every day, and experience it, but when it
comes to past populations, understanding behaviour is largely
mediated by our ability to read it in bones. Behaviour in Our
Bones: How Human Behaviour Influences Skeletal Morphology examines
how human physical and cultural actions and interactions can be
read through careful analyses of skeletal human remains. This book
synthesises the latest research on reconstructing behaviour in the
past. Each chapter is dedicated to a specific region of the human
body, guiding the reader from head to toe and highlighting how
evidence found on the skull, shoulder, thorax, spine, pelvis, and
the upper and lower limbs has been used to infer patterns of
activity and other behaviour. Chapter authors expertly summarise
and critically discuss a range of methodological, theoretical, and
interpretive approaches used to read skeletal remains and interpret
a wide variety of behaviours, including tool use, locomotion,
reproduction, health, pathology, and beyond.
The most recent developments in research on hepatic encephalopathy,
inborn hyperammonaemic syndromes and nitrogen metabolism, including
clinical aspects, were presented by international acknowledged
experts in this active research field at the 12th International
Symposium on Hepatic Encephalopathy, which was held from June 1 to
4, 2005 in Solingen, Schloss Burg, Germany. This book
comprehensively summarizes the most important novel issues on
hepatic encephalopathy and nitrogen metabolism and is of interest
not only for scientists in the field, but also for interested
clinicians. This update of present knowledge will provide a
platform for future research in the field of hepatic encephalopathy
and nitrogen metabolism.
The nitrogen-containing ring structures are at the hub of
metabolism and include ATP, nucleic acids, many coenzymes,
metabolic regulators and integrators such as adenosine and GTP,
signalling compounds such as cyclic nucleotides and plant
cytokinins and biochemically functional pigmets of which
haemoglobin, the cytochromes and chlorophyll are examples. This
important book collates and integrates current knowledge of all the
biologically important N-heterocyclic compounds, covering the
relationship between their chemical structures and physiological
functions within this key group of compounds. Few biochemical
reaction sequences do not involve one of these compounds as a
substrate, product or coenzyme and a full understanding of the
interrelationship between their structure and function is vital for
all those woorking in the field of biochemistry. Professor Eric
Brown who has a huge wealth of experience in teaching and research
on these compounds has written a very comprehensible and thorough
book which will be of great value for advanced students and
researchers in biochemistry and those at the interfacing subject
areas of chemistry, biology and pharmacology including all those
employed in researching biological function within pharmaceutical
companies.
Research over the years has demonstrated that free radicals
mediated oxidative stress lies at the helm of almost all
patho-physiological phenomena. These findings emphasize on the need
to understand the underlying molecular mechanism(s) and their
critical role in the pathogenesis. This book aims to focus on these
areas to provide readers a comprehensive outlook about the major
redox sensitive pathways and networks involved in various disease
conditions. In the first chapter of the book, basic information
about the oxidative stress, its generation, its biomarkers and its
role in body are discussed. In the next three chapters, the role of
oxidative stress in various pathologies ranging from neurological
disorders, to cardiovascular diseases, cancers, metabolic diseases
and ageing have been described. Chapter 5 cumulatively describes
the most important molecular signaling pathways that are affected
by reactive oxygen species (ROS). These are the mechanisms which
are common denominators in various pathological states. In the next
part of the book, various antioxidant strategies to target and
mitigate ROS have been discussed with details on the mechanisms.
Selenium, being the research focus and interest of the authors for
years, the role of selenium as an antioxidant as part of
selenoproteins has been included in the book. Finally, the book
culminates with authors' perspective on the future of the redox
biology field. Throughout the book, efforts have been made to use
simplified language and suitable figures for ease to understand the
contents. Although the authors have tried to touch on all the
different aspects of oxidative stress in detail, the fact that it
is a continuously growing field with updates coming every day,
there might be some areas which might not be described in depth.
This book is designed for students, young scientists to get
acquainted with the redox biology. Overall, this book is a
reference to understand the redox regulation of cellular signaling
pathways involved in pathogenesis.

syndrome, thyroid disease, and hypoglycemia; the evaluation of
endocrine-induced hypertension; the assessment of dyslipidemia and
obesity; and approaches to diagnosing hyper- and hypocalcemia.
There are also discussions of osteoporosis, hypogonadism and
erectile dysfunction, and hyperandrogenism in women. The authors
each review the complex physiological basis of the relevant
endocrine processes and provide richly instructive recommendations
for followup and long-term management of patients.
Atherosclerosis leading to coronary heart disease and to
cerebrovascular disorders is the number one cause of death in
industrialized societies. For the last two decades, great ad vances
have been made in understanding the pathogenesis of those
disorders. Recent studies have revealed that the earliest event in
atherogenesis is the adhesion of circulating leukocytes to the
vascular endothelial cells and their migration into the
subendothelial space. These cells are known to playa central role
in the formation of a fatty streak consist ing of lipid-laden foam
cells. As pathological events continue, the lesion is converted to
a more fibrous lesion associated with vascular smooth muscle cells.
To solve the enigma of this complicated process, intensive studies
in molecular biology have disclosed the genes involved in those
events. Some of the genes have been verified by creation of novel
animal models, which have led to novel therapeutic strategies for
subjects with atherosclerosis. This volume contains papers
presented at the International Symposium on Lipoprotein Metabolism
and Atherogenesis held in Kyoto December 5-8, 1998, supported in
part by the Japan Intractable Diseases Research Foundation. The
following three topics were the focus of the three-day program: I)
The molecular approach to studying risk factors and prevention 2)
The creation of novel animal models 3) Lipoprotein disorder as a
cause of activation of vascular endothelial cells Thirty
distinguished researchers from the United States, the United
Kingdom, Austria, Finland, Australia, and Japan were invited.

biochemistry to their physiological consequences in both health and
illness. The distinguished contributors integrate a wide range of
topics, including the basic biochemistry of EFAs and lipid
metabolism, the role of EFAs in the neuronal membrane, the effects
of EFAs and lipids in various diseases, and the effects of normal
levels and EFA deficiencies on cognition and behavior. The book's
consolidation of our knowledge of the biology and metabolism of the
EFAs lays the groundwork for dramatic advances in our understanding
of these ubiquitous biochemicals and their role in health and
illness.
Systems Metabolic Engineering is changing the way microbial cell
factories are designed and optimized for industrial
production.

from synthetic biology enables the global analysis and engineering
of microorganisms and bioprocesses at super efficiency and
versatility otherwise not accessible. Without doubt, systems
metabolic engineering is a major driver towards bio-based
production of chemicals, materials and fuels from renewables and
thus one of the core technologies of global green growth. In this
book, Christoph Wittmann and Sang-Yup Lee have assembled the world
leaders on systems metabolic engineering and cover the full story
from genomes and networks via discovery and design to industrial
implementation practises.
This book is a comprehensive resource for students and researchers
from academia and industry interested in systems metabolic
engineering. It provides us with the fundaments to targeted
engineering of microbial cells for sustainable bio-production and
stimulates those who are interested to enter this exiting research
field.
The metabolic syndrome is a common syndrome affecting about 20 % of
the adult population in Europe, and probably the prevalence is of
the same magnitude in other industrialised countries worldwide. It
is mainly caused by western lifestyle resulting in abdominal
obesity, but also a genetic predisposition plays a role. This
syndrome, which is linked to leisure lifestyle and
overeating/obesity, can develop into type 2 diabetes,
cardiovascular disease and cancer. Therefore, proper treatment and
prevention are heavily needed. This book discusses lifestyle
intervention and treatment, specifically with pharmacological
compounds, in order to formulate a strategy for treating the
metabolic syndrome in the daily clinic.
The heart has a very high energy demand but very little energy
reserves. In order to sustain contractile function, the heart has
to continually produce a large amount of ATP.The heart utilizes
free fatty acids mainly and carbohydrates to some extent as
substrates for making energy and any change in this energy supply
can seriously compromise cardiac function.It has emerged that
alterations in cardiac energy metabolism are a major contributor to
the development of a number of different forms of heart disease.It
is also now known that optimizing energy metabolism in the heart is
a viable and important approach to treating various forms of heart
disease.
"Cardiac Energy Metabolism in Health and Disease" describes the
research advances that have been made in understanding what
controls cardiac energy metabolism at molecular, transcriptional
and physiological levels.It also describes how alterations in
energy metabolism contribute to the development of heart
dysfunction and how optimization of energy metabolism can be used
to treat heart disease.The topics covered include a discussion of
the effects of myocardial ischemia, diabetes, obesity, hypertrophy,
heart failure, and genetic disorders of mitochondrial oxidative
metabolism on cardiac energetics.The treatment of heart disease by
optimizing energy metabolism is also discussed, which includes
increasing overall energy production as well as increasing the
efficiency of energy production and switching energy substrate
preference of the heart. This book will be a valuable source of
information to graduate students, postdoctoral fellows, and
investigators in the field of experimental cardiology as well as
biochemists, physiologists, pharmacologists, cardiologists,
cardiovascular surgeons and other health professionals."
The book focuses on the latest discoveries on calreticulin,
calnexin and other endoplasmic reticulum proteins. Calreticulin has
been implicated to affect diverse cellular function and play a role
in many pathologies including protein folding disorders, cardiac
pathologies, cancer and autoimmunity. This book contains
contributions from the world leaders in the area of endoplasmic
reticulum function, protein folding, Calcium homeostasis and
autoimmunity. It raises many intriguing questions about
calreticulin, calnexin and the endoplasmic reticulum and gives a
unique opportunity to realize the significance of these
calcium-binding chaperones. The book is unique in every respect and
we are not aware of any other publication focusing on these aspects
of endoplasmic reticulum biology. Because of a central role of
endoplasmic reticulum, calreticulin and calnexin in virtually all
cellular functions, the book should be of interest to everyone in
the biological sciences.
The utilization of herbal medicine to treat endocrine and metabolic
disorders has garnered much attention within the past few decades.
Specifically, the popularity of using dietary supplements for the
management of chronic disorders has drastically increased, with a
wide variety of these products available over the counter. They
represent an attractive adjuvant to traditional therapy for their
lower toxicity and their easy accessibility. The identification of
such dietary compounds has prompted researchers to explore the vast
array of their beneficial effects. However, despite their
widespread use, there is still limited data on the safety and
efficacy of the products currently on the market. Current research
on the side effects and safe usage of herbal medicines is necessary
for providing optimal care and counseling for patients. Treating
Endocrine and Metabolic Disorders With Herbal Medicines is a
comprehensive reference book focused on spreading awareness on the
safety, potential harmful effects, and rational use of herbal
medicines. The chapters within explore and provide insight on the
effectiveness, versatility, and side effects of various herbal
medicines across a range of different diseases and conditions.
While highlighting herbal medicine in areas such as diabetes,
cancer, infertility, and endocrine disorders, this publication is
ideally intended for clinical practitioners, pharmaceutical
scientists, doctors, practitioners, stakeholders, researchers,
academicians, and students interested in enhancing their knowledge
and awareness in the field of complementary medicine.
