Food research (and funding) is becoming more and more focused on
health. While researchers and product developers have made great
strides in food engineering, there needs to be increased focus on
what happens when the food is actually digested. How is the food
absorbed? Do the benefits remain? Digestion is a complex topic, and
this will be the first book aimed at food researchers. Authored by
a physiologist and a food engineer, the book willbe a welcome
addition to the literature.

Recent research, which Bone- Metabolic Function and Modulators
expands on, has added new support to the idea that bone not only
serves as a support system, but also functions as an integrating
organ, with a significant regulatory role for lipid and energy
metabolism. Links between physical activity and the skeleton are
also becoming increasingly clear. This fully illustrated volume
contains up-to-date information on the metabolic role of the
skeleton and what this can mean for the treatment of metabolic as
well as skeletal and auditory diseases. Bone- Metabolic Function
and Modulators is of particular interest to clinician scientists,
clinical and basic bone researchers, orthopedists,
endocrinologists, internists, dentists, nurse practitioners,
medical and dental residents and physiotherapists as well as
students of the musculoskeletal system. Bone- Metabolic Function

This text covers the basic principles of mitochondrial dynamics in
cardiovascular medicine, with particular emphasis on their
functional roles in physiology and disease. The book will include
articles pertaining to mitochondrial fitness on a global basis,
providing therefore an update on the progress made in several
aspects in the field. Thus, it will assist scientists and
clinicians alike in furthering basic and translational research.
Organized in sections focusing on: basic science, mitochondrial
dysfunction in cardiac disorders, in vascular disorders, in
metabolic disorders, in kidney disease, therapeutic challenges and
options, this essential volume fills imperative gaps in
understanding and potentially treating several cardiovascular
disorders.
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.
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.
Experienced physicians concisely explain the pathophysiology and
clinical manifestations of endocrine disorders and survey all the
latest laboratory diagnostics. Topics range widely from an overview
of the diagnosis of diabetes and the long-term monitoring of its
complications to the evaluation of menstrual dysfunction. Coverage
is also given to the diagnosis of pituitary tumors, Cushing's
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.
This book discusses the relationship between cellular immunity and
tryptophan metabolism, as well as its products, serotonin and
melatonin, in the development of several diseases and reappraises
the common signal transduction pathways of the neurodegenerative
diseases, carcinogenesis, immune tolerance, inflammation,
hypersensitivity reactions, neuropsychiatric disorders, in addition
to bacterial tryptophan biosynthesis and novel antimicrobials.
Tryptophan Metabolism: Implications for Biological Processes,
Health and Disease presents fundamental information on tryptophan
related metabolic pathways and metabolites, implications of these
products for specific biological processes, diseases and
conditions. This book focuses on effects of tryptophan metabolites
on human health and will appeal to researchers, clinicians and
students within this field.
Internationally eminent scientists illuminate the most important
scientific aspects of essential fatty acids (EFAs)-from their
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.
Integrating systems biology and biotechnology with new concepts
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.
