JIMD Reports publishes case and short research reports in the area
of inherited metabolic disorders. Case reports highlight some
unusual or previously unrecorded feature relevant to the disorder,
or serve as an important reminder of clinical or biochemical
features of a Mendelian disorder.
Hepatic Encephalopathy and Nitrogen Metabolism is an
interdisciplinary symposium bringing together basic science and
clinical applications. It contains up-to-date research findings at
the highest scientific level.
This is the first comprehensive volume on Dipeptidyl
Aminopeptidases that can be marketed to a wide variety of
disciplines, as well as to a variety of clinicians. Leading experts
in the field contribute to this state-of-the-art view on these
enzymes. This book comes at a time when our understanding of their
function is growing ever more rapidly and therapeutic options have
become imminent.
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.

Kernicterus (bilirubin encephalopathy) is a highly interesting
example of metabolic encephalopathy. It fills all the
characteristics of a metabolic encephalopathy in that it can
develop rapidly, produces signature signs and symptoms, and is
amenable to successful treatment. In the absence of treatment
kernicterus can produce devastating sequelae and death. The present
volume will examine the biochemistry and physiology of bilirubin as
well as its hepatic metabolism and renal excretion. Chapters will
elaborate bodily disposition of bilirubin and its neuropathology.
Both early treatments and current therapy will be discussed in
detail. Phototherapy will be presented, and its efficacy and
influence on incidence thoroughly examined.
Excess of homocysteine, a product of the metabolism of the
essential amino acid methionine, is associated with poor health, is
linked to heart and brain diseases in general human populations,
and accelerates mortality in heart disease patients. Neurological
and cardiovascular abnormalities occur in patients with severe
genetic hyperhomocysteinemia and lead to premature death due to
vascular complications. Although it is considered a non-protein
amino acid, studies over the past dozen years have discovered
mechanisms by which homocysteine becomes a component of proteins.
Homocysteine-containing proteins lose their normal biological
function and become auto-immunogenic and pro-thrombotic. In this
book, the author, a pioneer and a leading contributor to the field,
describes up-to date studies of the biological chemistry of
homocysteine-containing proteins, as well as pathological
consequences and clinical implications of their formation. This is
a comprehensive account of the broad range of basic science and
medical implications of homocysteine-containing proteins for health
and disease.

Recent developments in research on diabetes mellitus embrace basic
disciplines such as physiology, biochemistry, morphology and
evolving sub-specialities. Fundamental studies on the heterogeneous
diabetic syndrome are oriented towards regulatory principles of
cell metabolism, genetic control mechanisms of insulin biosynthesis
and secretion, as well as autoimmune events implicated in selective
destruction of pancreatic ss-cell. In parallel, efforts are made
for a better understanding of normal versus impaired biological
actions, both of insulin and insulin-like growth factor I, and the
translocation process of glucose transporters in insulin-responsive
target cells."
The scientific advances in the physiology and pathophysiology of
adipose tissue over the last two decades have been considerable.
Today, the cellular and molecular mechanisms of adipogenesis are
well known. In addition, adipose tissue is now recognized as a real
endocrine organ that produces hormones such as the leptin acting to
regulate food intake and energy balance in the central nervous
system, a finding that has completely revolutionized the paradigm
of energy homeostasis. Other adipokines have now been described and
these molecules are taking on increasing importance in physiology
and pathophysiology. Moreover, numerous works have shown that in
obesity, but also in cases of lipodystophy, adipose tissue was the
site of a local low-grade inflammation that involves immune cells
such as macrophages and certain populations of lymphocytes. This
new information is an important step in the pathophysiology of both
obesity and related metabolic and cardiovascular complications.
Finally, it is a unique and original work focusing on adipose
tissue, covering biology and pathology by investigating aspects of
molecular and cellular biology, general, metabolic, genetic and
genomic biochemistry.

The Fourteenth Midwest Conference on Endocrinology and Metab olism,
held at the University of Missouri - Columbia on September 28th and
29th, 1978, brought together several prominent researchers who are
authorities on various aspects of the renin-angiotensin system.
Each speaker presented an in-depth coverage of a topic related to
his own area of expertise, including recent findings from his own
research laboratory. Following each presentation thet:e was a
general discussion of the material by the speaker and the audience.
These presentations and the ensuing discussions are summarized in
these published Proceedings. Traditionally the Midwest Conferences
on Endocrinology and Metabolism have emphasized breadth as well as
depth of coverage of the selected topic; the present Conference is
no exception. Perusal of the titles of the presentations will
reveal that the Conference dea1th with many different facets of the
renin-angiotensin system, including the biochemistry, anatomy,
physiology, and comparative endocrinology of this hormonal system,
plus special areas of con sideration such as angiotensin receptors,
angiotensin-converting enzyme, the control of renin release,
angiotensin and aldosterone secretion, and the role of the
renin-angiotensin system in the central nervous system. The
selection of the renin-angiotensin system as the topic for the
present conference was very timely because of the many noteworthy
advances in this area in recent years, many by the participants in
the Conference. The Editors are very appreciative of the excellent
manuscripts which the speakers provided for these Proceedings.
The renewal of interest in excitatory amino acids in the 1980s has
altered the direction of neurobiology. L-Glutamate, widely regarded
as a general perpetu- ator of nonspecific excitation, has become
generally regarded as a widely dis- tributed and important
neurotransmitter in the CNS. In the past three decades evidence has
accumulated that excitatory amino acids are involved in many
neurological diseases and that pharmacological intervention may
offer pros- pects of novel and more effective therapies. Numerous
studies on experimen- tal animals demonstrate that excitatory amino
acid antagonists have anxio- lytic, antiepileptic and muscle
relaxant effects. Particular interest has developed in the possible
neuroprotective efficacy of excitatory amino acid receptor
antagonists in neurological diseases such as hypoxia/ischemia,
hypo- glycemia, epilepsy, and chronic neurodegenerative disorders
(Huntington's, Alzheimer's, and Parkinson's disease, amyotrophic
lateral sclerosis, and AIDS). Thus, the drugs changing
neurotransmission mediated by excitatory amino acids possess
potential therapeutic value. This volume is part of the Schering
Research Foundation Workshop Series. It is the goal of the Schering
Research Foundation to promote the asso- ciation between industrial
and basic research. The support and the organiza- tion of highly
qualified symposia belong to the armamentarium by which this
purpose is fulfilled, and we are convinced that the workshop
"Excitatory Amino Acids and Second Messenger Systems" has
contributed to this. Gunter Stock Ursula-F.
Stjarne: The present review puts the emphasis on two important
developments: the discovery that individual postganglionic
sympathetic neurons may secrete multiple transmitter substances
from different classes of vesicles and by different mechanisms, and
the introduction of new techniques which may permit for the first
time direct impulse by impulse analysis of transmitter secretion in
individual sympathetic nerve varicosities. Illes: Exogenous and
endogen opioid peptides elicit a number of effects in the organism,
usually by modifying the function of transmitter and hormone
systems, for example, activation of multiple opioid receptors. The
effects of opioids on transmitter and hormone release have
frequently been reviewed. This review gives a detailed overview on
the involvement of multiple opioid receptors in these processes.
Rothstein: This article gives an overview of the exchange in
acidification and transepithelial salt and water transfer in
nonepithelial cells. Delineating the exchanger's most important,
common features, and concentrating particularly on its role in cell
pH and volume regulation.
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.
These two volumes contain articles presented at the Vlth
International Symposium on Human Purine and Pyrimidine Metabolism
held in Hakone, Japan, July 17 trough 21, 1988. The first meeting
of this series of symposia convened in Tel Aviv, Israel, and since
then meetings have taken place every three years in various parts
of the world. The second meeting was held in Baden, Austria, the
third in Madrid, Spain, the fourth in Maastricht, the Netherlands,
and fifth in San Diego, California. The Vlth meeting in Hakone
marked the first such symposium held in Asia. On occasion of
publishing these books, I would like to describe how research in
this field has evolved in Japan. Early in the 1950s, I was engaged
in clinical practice treating various rheumatic diseases as an
orthopedicist, and found that a substantial percentage of our
patients had symptoms apparently compatible with gout. During the
1960s, the number of these gouty patients increased, and in the
1970s, research on the pathogenesis of gout was performed on the
basis of approximately 2,000 cases of this disease, together with
precise epidemiological studies concerning gouty and hyperuricemic
individuals. Data derived from the two kinds of study had greatly
changed the notion that gout was a rare disease among Japanese. My
clinical studies have been succeeded by research at the molecular
level on various purine metabolic abnormalities, including not only
gout but also other diseases with various symptoms of wide clinical
spectra.

Obesity is a risk factor for breast cancer in older women. A number
of adipose-derived and obesity-related factors have been shown to
affect tumour cell growth. These include adipokines, insulin, IGF-1
and oestrogens. The majority of obesity-related postmenopausal
breast cancers are oestrogen-dependent. Since the ovaries no longer
produce oestrogens after menopause, and that circulating levels are
negligible, it is evident that it is the oestrogens produced
locally within the breast adipose that are responsible for the
increased growth of breast cancer cells. Aromatase is the enzyme
that converts androgens into oestrogens and its regulation is
dependent on the activity of a number of tissue-specific promoters.
Targeting oestrogen biosynthesis in obesity may be useful for the
prevention of breast cancer. Aromatase inhibitors are efficacious
at treating postmenopausal breast cancer and recent studies suggest
that they may also be useful in the prevention setting. However,
these compounds inhibit the catalytic activity of aromatase and as
a consequence lead to a number of undesirable side-effects,
including arthralgia and possible cognitive defects due to
inhibition of aromatase in the bone and brain, respectively. Novel
therapies, such as those employed to treat obesity-associated
disease, including anti-diabetics, may prove successful at
inhibiting aromatase specifically within the breast. This
SpringerBrief will explore all of these issues in depth and the
authors are in a unique position to write about this topic, having
extensive experience in the field of aromatase research.
With the invitation to edit this volume, I wanted to take the
opportunity to assemble reviews on different aspects of circadian
clocks and rhythms. Although most c- tributions in this volume
focus on mammalian circadian clocks, the historical int- duction
and comparative clocks section illustrate the importance of various
other organisms in deciphering the mechanisms and principles of
circadian biology. Circadian rhythms have been studied for
centuries, but only recently, a mole- lar understanding of this
process has emerged. This has taken research on circadian clocks
from mystic phenomenology to a mechanistic level; chains of
molecular events can describe phenomena with remarkable accuracy.
Nevertheless, current models of the functioning of circadian clocks
are still rudimentary. This is not due to the faultiness of
discovered mechanisms, but due to the lack of undiscovered
processes involved in contributing to circadian rhythmicity. We
know for example, that the general circadian mechanism is not
regulated equally in all tissues of m- mals. Hence, a lot still
needs to be discovered to get a full understanding of cir- dian
rhythms at the systems level. In this respect, technology has
advanced at high speed in the last years and provided us with data
illustrating the sheer complexity of regulation of physiological
processes in organisms. To handle this information, computer aided
integration of the results is of utmost importance in order to d-
cover novel concepts that ultimately need to be tested
experimentally.
