This book was released on 1991 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis aims to demonstrate the usefulness of Nuclear Magnetic Resonance Spectroscopy in understanding normal human placental and uterine metabolism as well as its application in the study of gestational and gynecological disorders. We have used phosphorus-31 NMR spectroscopy on isolated samples of placenta and uterus (myometrium and endometrium). Our studies have revealed interesting correlations between spectral characteristics and the type of tissue studied, normal and abnormal. The $sp{31}$P spectrum of placenta changes as it matures with increasing gestational age. In addition, complications of pregnancy, including intrauterine growth-retardation and hydatidiform mole, are associated with significant changes in the placental spectrum. Absolute volume of intracellular water and intracellular concentrations of normal placental phosphorus metabolites were obtained. The effects of pregnancy are manifested in the NMR spectra of normal pregnant myometria. Experiments on nonpregnant diseased uterus have revealed presence of disease in histologically normal tissue obtained close to a uterine lesion. We have also demonstrated feasibility and cost-effectiveness of evaluation of endometrial biopsies by NMR prior to histopathological examination.
Download or read book Placental Pharmacology written by B. V. Rama Sastry and published by CRC Press. This book was released on 1996-05-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Placenta plays a very significant role in the development of secretory and regulatory functions for the maintenance of pregnancy and in the nutrition of the embryo. It shares many functions of the heart, lung, liver, endocrines, and other organs. In Placental Pharmacology, fourteen expert authors discuss how placenta and its component parts can be used effectively in drug development research and in the study of transfer mechanisms across membranes. This reference begins by describing the use of modern biophysical methods to study placental function and prospects for their application in pharmacological research. The next three chapters deal with placental hemodynamics, use of placental tissues and cells in pharmacological assays, and placental transfer of drugs used in pregnancy. Three more chapters contain up-to-date information on molecular biological aspects of placenta currently receiving lots of attention - phospholipase A2 isozymes, imprinted genes and embryogenesis, and placental growth factors. The final chapter describes the clinically relevant topics of placental metabolism and toxicity of homocysteine in placenta. Easy to understand, thorough, and complete, Placental Pharmacology is the perfect resource for scientists interested in placenta and its uses in drug development and testing.
Download or read book Uterine Function written by M.E. Carsten and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frontispiece, Leonardo da Vinci's drawing of the embryo in the womb, was chosen as a starting point for this book. It was Leonardo who in his notebooks and drawings combined artistic composition and accurate recording of the anatomy of the human body. Leonardo studied human anatomy in order to execute artistic drawings. His aim was to clarify form and function of human organs including reproductive organs. He followed up his extensive research with graphic representa tion and thereby initiated record keeping as a basis of scientific investigation. His records, accurate three-dimensional drawings, allowed others to reproduce his find ings and to test for correctness. Results could be updated and refined. Only after these steps can abnormalities be ascertained and defined as pathology. Though Leonardo was both artist and scientist, it is assumed that his anatomic drawings were used to improve his art, and thus scientific endeavor was at the service of his art. Anatomy, the offspring of science and art, is an integration of the two and became an accepted branch of the natural sciences. Although art and science continued to interact throughout the Renaissance, art was often placed in the service of science. In the course of history that followed, art and science in creasingly followed separate ways.

Download or read book SILENT RISK written by Jason H. Collins, MD, MSCR and published by Xlibris Corporation. This book was released on 2013-10 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an estimated 8,000 deaths per year in the United States from complications of UCA, an initial goal of 50% reduction of loss is possible. To achieve this goal requires the recognition by the obstetrical community of the issue. Recent research into circadian rhythms may help explain why UCA stillbirth is an event between 2:00 a.m. and 4:00 a.m. Melatonin has been described as stimulating uterine contractions through the M2 receptor. Melatonin secretion from the pineal gland begins around 10:00 p.m. and peaks to 60 pg at 3:00 a.m. Serum levels decline to below 10 pg by 6:00 a.m. Uterine stimulation intensifies during maternal sleep, which can be overwhelming to a compromised fetus, especially one experiencing intermittent umbilical cord compression due to UCA. It is now time for the focus to be on screening for UCA, managing UCA prenatally, and delivery of the baby in distress defined by the American College of Obstetricians and Gynecologists as a heart rate of 90 beats per minute for 1 minute on a recorded nonstress test. The ability of ultrasound and magnetic resonance imaging (MRI) to visualize UCA is well documented. The 18 20 week ultrasound review should include the umbilical cord, its characteristics, and description of its placental and fetal attachment. The American Association of Ultrasound Technologists has defined these parameters for umbilical cord abnormalities: B.1.4 Abnormal insertion B.1.5 Vasa previa B.1.6 Abnormal composition B.1.7 Cysts, hematomas, and masses B.1.8 Umbilical cord thrombosis B.1.9 Coiling, collapse, knotting, and prolapse B.1.10 Umbilical cord evaluation with sonography includes the appearance, composition, location, and size of the cord Cord Events: Although many stillbirths are attributed to a cord accident, this diagnosis should be made with caution. Cord abnormalities, including a Nuchal Cord, are found in approximately 30% of normal births and may be an incidental finding. (American College of Obstetrics and Gynecology Practice Bulletin 2009) According to NICHD's recent stillbirth study, UCA is a significant cause of mortality (10%). This finding is in agreement with other international UCA studies. (Bukowski et al. 2011) These histologic criteria identify cases of cord accident as a cause of stillbirth with very high specificity. (Dilated fetal vessels, thrombosis in fetal vessels, avascular placental villi.) (Pediatr Dev Pathol 2012) Finally, defining the morbidity (injury) of cord compression, such as fetal neurologic injury or heart injury identified with umbilical cord blood troponin T levels or pulmonary injury, is the next major area of investigation.

Download or read book Uterus Transplantation written by Mats Brännström and published by Springer Nature. This book was released on 2019-11-30 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses all aspects of the uterus transplantation procedure in women who are childless because of a dysfunctional or missing uterus, from initial pre-operative investigations to follow-up after the uterine graft has been removed. All the international experts who are engaged in clinical activities and/or research in this field have contributed one or more of the book’s chapters. Since the first live birth following uterus transplantation was reported in Sweden in September 2014, the field has been rapidly evolving around the globe: the first cases in USA, Germany, China, Brazil, and Czech Republic were performed in 2016 and several other centres are preparing for clinical trials of uterus transplantation. Uterus transplantation is a subject that attracts the attention of many bioethicists, and like all other major procedures in transplantation surgery and assisted reproduction techniques, it is a complex process that requires a multidisciplinary team if it is to be successful. As such the book is a valuable resource not only for clinicians from many disciplines, but also for nurses, ethicists, psychologists and researchers.
