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. - Provides updated information on a complex and changing subject in five sections - Reviews historical perspectives and developments over the last 100 years - Includes novel insights into the structure, function and detection of hCG in pregnancy and cancer - Includes chapters on the use of mass spectrometry to detect and quantify hCG as well as traditional immunoassays and over the counter pregnancy tests - Describes the role of hCG in pregnancy, endometrial receptivity and embryo implantation and the use in fertility treatment - Addresses the specific hyperglycosylated hCG test that can distinguish a normal term from a failing pregnancy and also screen for preeclampsia and gestational hypertension in pregnancy as well as its use as a marker and treatment target in cancer. - Includes chapters on the development and use of hCG vaccines - Includes a section on hCG and in subunits in cancer
Human chorionic gonadotropin (hCG) is produced during pregnancy by the embryo. It promotes progesterone production by corpus luteal cells. It also functions in pregnancy to promote angiogenesis in uterine vasculature, it immuno-blands the invading placental tissue so it is not rejected by the maternal uterine tissues, promotes the growth of the uterus in line with the growth of the fetus, promotes the differentiation of growing cytotrophoblast cells, promotes the quiescence of contractions in the uterine myometrium during the course of pregnancy, and also has function in growth and development of fetal organs. The book describes the detailed biology, clinical chemistry, and clinical perspectives of hCG and associated molecules, and examines hCG, hyperglycosylated hCG and hCG free ß-subunit, 3 separate and independent molecules with totally sovereign physiological functions. It provides comprehensive information on hCG from basic science to clinical medicine Written by specialists in the field
Human Gonadotropins is a must-have reference for basic science researchers looking to maximize their knowledge in this specific field of study. Luteinizing hormone, follicle-stimulating hormone, and human chorionic gonadotropin are essential for reproduction and outlined in detail in this work, covering topics ranging from antibodies and immunoassays, to commercial products and standards, genetics, and receptors and intermediaries for gonadotropins. Dr. Laurence Cole has been recognized for his outstanding research throughout his illustrious career. He has received awards from the Institute for Anticancer Research, Biannual Prize for best research; American Association for Clinical Chemistry, Most Outstanding Research Contributor to Clinical Chemistry Prize; Gynecology Oncology, Outstanding Speaker Award; and International Society for Study of Trophoblastic Disease, Gold Medal for most outstanding research. This detailed resource compiles all the recent research together into one volume, with one consistent voice. - Covers the evolution, structure, synthesis, and functions of gonadotropins in meticulous detail - Includes sections on Degradation, Antibodies and Immunoassays, Commercial Products and Standards, and Receptors and Intermediaries - Details a section on Reproduction and Cancer, covering gestational trophoblastic diseases, ovarian cystic disorders, and hCG and cancer
This important new publication summarises the recent exciting advances in screening for Down's syndrome. It addresses important clinical questions such as: risk assessment, who to screen, when to screen, which techniques to use, and the organisation of screening programmes nationally and internationally. An international and authoritative team of authors has been invited to assess the latest developments in this rapidly advancing area. The volume provides a critical and much needed evaluation of the potential and limitations of new and established techniques for screening for Down's syndrome. It will serve as an essential source of information for all those involved in pre-natal diagnosis and the provision of obstetric care.
Presents almost 100 common and uncommon gynecologic problems encountered in urgent and emergency settings with an emphasis on practical management.
HOWARD W. JONES, JR. (1910-2015) was one of the most charismatic and ingenious figures of his generation in American medicine. From before his World War II service as a battlefield surgeon, he was pioneering advances in surgery and gynecological oncology and endocrinology at Johns Hopkins University Medical School alongside his distinguished wife and collaborator, GEORGEANNA SEEGAR JONES, M.D. (1912-2005). After reaching the mandatory age for retirement, they moved from Baltimore to Norfolk, Virginia, where they launched the nation's first in vitro fertilization (IVF) program for patients with infertility. Dr. Jones' humanity, longevity, and industriousness were legendary; he published three books after becoming a centenarian. This last book includes a chapter from his late wife's unpublished lectures, another chapter by his longtime assistant Nancy Garcia, and a prologue by the editors, Drs. Lucinda Veeck Gosden and Roger G. Gosden, who were his former colleagues. Includes illustrations, family memories, and short tributes to the Joneses from over a hundred friends, colleagues, and patients around the world.
This book covers the entire spectrum of gestational trophoblastic disease from the most benign to the most malignant form. It addresses etiopathogenesis, molecular basis of the disease, risk assessment, management and follow-up. Management in the form of surgical, medical and supportive care is discussed in detail to help the practitioner in making treatment decisions. Special and rare varieties of the disease are be dealt separately. A separate section in each chapter covers critical conditions arising from the disease. Case based discussions make the chapters more lively and interesting. The recent trials and studies are also covered in the book. Topics such as fertility preservation, gestational trophoblastic diseases registry and development of voluntary organizations for supporting patients are value additions to this book. This book is meant for the general obstetrician and gynecologist and for the gynaecologic oncologist as well.
Human chorionic gonadotropin (hCG) is produced during pregnancy by the embryo. It promotes progesterone production by corpus luteal cells. It also functions in pregnancy to promote angiogenesis in uterine vasculature, it immuno-blands the invading placental tissue so it is not rejected by the maternal uterine tissues, promotes the growth of the uterus in line with the growth of the fetus, promotes the differentiation of growing cytotrophoblast cells, promotes the quiescence of contractions in the uterine myometrium during the course of pregnancy, and also has function in growth and development of fetal organs. The first edition described the detailed biology, clinical chemistry, and clinical perspectives of hCG and associated molecules, and examines hCG, hyperglycosylated hCG and hCG free ß-subunit, 3 separate and independent molecules with totally sovereign physiological functions. The second edition will include coverage of the many new discoveries that have been made in the last five years: hCG analogues may be the actual driving signal of all human cancers. The editor estimates that 40% of the out of date material will be excluded and replaced with 40% of the exciting new findings. The book will also have a much clearer pregnancy and cancer focus.
It is widely understood that stem cell treatments have the potential to revolutionize medicine. Because of this potential, in 2004 California voters approved Proposition 71 to set up a 10-year, $3 billion program to fund research on stem cells. Under the direction of the California Institute for Regenerative Medicine, this program will pay to build facilities for stem cell research and will fund doctors and scientists to carry out research with the ultimate goal of helping to develop therapies based on stem cells. For this research to move forward, however, will require a steady supply of stem cells, particularly human embryonic stem cells. Those stem cells are collected from developing human embryos created from eggs-or oocytes-harvested from the ovaries of female donors. Thus much of the promise of stem cells depends on women choosing to donate oocytes to the research effort. The oocyte donation process is not without risk, however. Donors are given doses of hormones to trigger the production of more eggs than would normally be produced, and this hormone treatment can have various side effects. Once the eggs have matured in the ovary, they must be retrieved via a surgical procedure that is typically performed under anesthesia, and both the surgery and the anesthesia carry their own risks. Furthermore, given the very personal nature of egg donation, the experience may carry psychological risks for some women as well. With this in mind, in 2006 the California Institute for Regenerative Medicine contracted with the National Academies to organize a workshop that would bring together experts from various areas to speak about the potential risks of oocyte donation and to summarize what is known and what needs to be known about this topic. The Committee on Assessing the Medical Risks of Human Oocyte Donation for Stem Cell Research was formed to plan the workshop, which was held in San Francisco on September 28, 2006. This report is a summary and synthesis of that workshop.
