100 years of Human Chorionic Gonadotropin: Reviews and New
Perspectives is a collection of articles written by some of the
world's leading experts on the pregnancy hormone and cancer marker
hCG. In 2019 it is difficult to ignore the effect that our
understanding of hCG has had on the lives of millions of people
worldwide. The hCG immunoassay, in one form or another, is now one
of the most common medical tests conducted and is often the first
indication that a mother-to-be is pregnant. Not only a marker of
pregnancy, hCG is utilized in the diagnosis and monitoring in
oncology and presents a potential target for novel cancer
therapeutics. 100 years ago, in 1919, Hirose was demonstrating
gonadotropic functions which resulted from a chorionic factor. Over
the last century this factor has become defined as hCG and more
recently explored as not one molecule but a group of molecules with
variable structure and variable functions in both pregnancy and
cancer. hCG is a multi-faceted molecule that has clinical and
therapeutic implications but can be a challenging topic for
researchers and physicians alike. This text covers the different
structures and functions of hCG exploring the genes and evolution
of the molecule, the different protein and glycosylation structures
which can exist and their effect on structure, detection and
quantification. 100 Years of hCG is not an attempt to recount the
history of every publication on hCG, but rather a collection of
reviews and new perspectives by "hCG-ologists", the term used by
Hussa to describe biochemists working on HCG in the first book
written on the topic over 30 years ago. Some of the authors have
been around a while, some not so long, but others are just
beginning their journey with a most beguiling molecule.
The Human Hypothalamus: Neuroendocrine Disorders, Volume 181 in the
Handbook of Clinical Neurology series, provides comprehensive
summaries of recent research on the brain and nervous system as
they relate to clinical neurology. This volume summarizes the role
of the hypothalamus in neuroendocrine disorders, identifying the
mechanism of action, disorder etiology, and best practices for
assessment and treatment. Disorders covered include pituitary
hypothalamic disorders of development and growth, hypothalamic
tumor related disorders, hypothalamic autoimmune disorders and
infection, disorders of vasopressin, water and sodium homeostasis,
eating disorders, and gonadotropic hormone regulation disorders.
This issue of Critical Care Clinics, Guest Edited by Dr. Rinaldo
Bellomo, focuses on Modern Critical Care Endocrinology. Article
topics include: Diabetes insipidus and SIADH in the ICU; Estrogen
therapy in ICU patients; The angiotensin family, ACE and ACE 2;
Angiotensin II in vasodilatory shock; Vasopressin in vasodilatory
shock; Hydrocortisone in vasodilatory shock; Erythropoietin in
trauma and critical illness; HbA1c and permissive hyperglycemia in
diabetic ICU patients; Osteoporosis and the critically ill patient;
New oral agents for the treatment of diabetes; Melatonin in
critical care; The incretins in ICU patients; Hepcidin; Thyroid
hormone therapy in the ICU; and Hormonal therapy in organ donors.
Obesity and diabetes develop as a complex result of genetic,
metabolic and environmental factors and are characterized by
increased lipogenesis and lipid accumulation in many tissues.
Stearoyl-CoA desaturase (SCD) genes are a critical regulator of
lipogenesis and catalyzes the synthesis of monounsaturated fatty
acids (MUFA), mainly oleoyl- (18:1n9) and palmitoleoyl-CoA
(16:1n7). These MUFAs are the major fatty acid substrates for the
synthesis of triglycerides, cholesterol esters, wax esters and
membrane phospholipids. There are 4 SCD isoforms (SCD1-4) in mice
and two (hSCD1 and hSCD5) expressed in humans. At first glance,
stearoyl-CoA desaturase enzyme would be considered a housekeeping
enzyme because it synthesizes oleate a well-known fatty acid that
is abundant in many dietary sources. However numerous studies have
shown that SCD is a very highly regulated enzyme that features in
so many physiological processes ranging from fat differentiation,
carbohydrate and fat metabolism, inflammation and cancer. The
editor's studies using stearoyl-CoA desaturase knockout (SCD1-/-)
mice and studies of other investigators using pharmacological
approaches to reduce SCD1 expression in mouse tissues have all
established that the expression of SCD1 gene isoform represents a
key step in partitioning of lipids between storage and oxidation.
High SCD expression favors fat storage leading to obesity while
reduced SCD expression favors fat burning and leanness. Although
these studies clearly illustrated that SCD1 expression is involved
in the development of obesity and insulin resistance, questions
remain in the elucidation of the mechanisms involved and role of
SCD1. This book includes chapters by leading researchers on SCD
Genes in the brain, heart, muscle, liver metabolism, Colitis, and
more.
Maternal-Fetal and Neonatal Endocrinology: Physiology,
Pathophysiology, and Clinical Management systematically examines
the normal and abnormal endocrinology of the pregnant and lactating
female and of the fetus and neonate. This reference volume expands
coverage of specific disorders and diseases beyond the current
endocrinology content on the market, which in most cases has a
paragraph or no mention at all about pregnancy or aspects of
fetal/neonatal development.
