This book was released on 2012-12-06 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human reproduction is the most dynamic of processes. The events which lead to the birth of a normal healthy infant have their origin long before actual fertilization. Indeed, the whole process can be looked upon as a continuum. Human fertilization and early development, once sequestered in the protective environment of the fallopian tubes and uterus, have now been exposed in the laboratory. These events have, over time, been extensively observed and catalogued in animal models. The tools of modem morphology and molecular biology have reopened issues long since considered settled as facets of early reproduction are reexplored. This volume, consisting of the proceedings of a workshop on uterine and embryonic factors in early pregnancy, has been designed to enhance that effort. Attention is focused largely on early embryonal development with special attention to the interrelationship between the embryo and the uterus in early pregnancy. Each of the contributing scientists brings with him or her the perspective of one specific discipline or another. The common denominator is the application of emerging techniques in modem molecular biology to problems pertaining to embryonal-uterine interaction. The goal is to consider specific areas of concern in a multidisciplinary way and to reexplore the factors behind early development and implantation. Uterine complement, the function of uterine macrophages immunoregulatory loops in the peri-implantation period, colony stimulating factors and interferon-like factors are reviewed and their interrelationship explored. Uterine angiogenesis factors as well as embryonic growth factors are also considered.
Book Synopsis Pregnancy After Assisted Reproductive Technology by : Eric Jauniaux
Download or read book Pregnancy After Assisted Reproductive Technology written by Eric Jauniaux and published by Cambridge University Press. This book was released on 2012-09-06 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that more than 4.5 million couples experience infertility each year, and more than 4 million babies have been born using IVF since 1978. However, assisted reproductive technologies continue to raise many medical, social, ethical, political and religious questions, often leading to controversial and sometimes inaccurate opinions about the outcomes of pregnancies resulting from these techniques. This is the first book dedicated to pregnancies arising from assisted reproductive technologies (ART). Chapters cover the most important management issues, from early pregnancy to outcome of children resulting from ART, including gynaecological, genetic and obstetric complications. Each chapter is written and edited by leading experts in the field of human reproduction. A timely, practical and evidence-based guide to the management of ART pregnancies, based on 30 years of clinical experience, this is essential reading for reproductive and maternal-fetal specialists as well as general obstetricians and gynaecologists.

Book Synopsis Immunological and Endometrial Changes of Early Pregnancy in Dairy Cattle by : Maria Da Silva
Download or read book Immunological and Endometrial Changes of Early Pregnancy in Dairy Cattle written by Maria Da Silva and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in bovine reproduction is crucial for enhancing fertility, efficiency, and sustainability in dairy production. Despite progress in breeding practices and herd health management, a significant number of bovine embryos do not survive past the first month of pregnancy. Factors like the immune system play a critical role in protecting against pathogens and tolerating the semiallogeneic embryo. Immune cells also mediate endometrial tissue remodeling and homeostasis during successful reproduction. However, little is known about immunological and endometrial changes during early pregnancy. To support pregnancy, the early conceptus secretes crucial proteins, including interferon tau (IFNT) that maintains the corpus luteum. Pregnancy-associated glycoproteins (PAGs) are another group of conceptus molecules abundantly secreted from the time of conceptus attachment until parturition, but their specific function remains unknown. In our first study (Chapter 2), we analyzed the transcriptome of the endometrium and blood leukocytes in cyclic heifers treated in vivo with intrauterine infusions of IFNT and PAG. IFNT activated interferon response, immune activation, inflammation, and cell death pathways in the endometrium, while downregulating genes related to vesicle transport and extracellular matrix (ECM) remodeling. Prolonged IFNT altered genes linked to cell invasion, retinoic acid (RA) signaling, and embryo implantation. In peripheral blood, PAG stimulated genes involved in leukocyte differentiation and TGFB signaling but had limited effects on endometrial genes. These findings shed light on how conceptus secretions impact endometrial and immune function during maternal recognition of pregnancy and embryo attachment/implantation. Shortly after attachment/implantation, the endometrium undergoes vascular remodeling to establish the maternal placenta. Adequate blood flow and vascular development are essential for successful embryo implantation, nutrient exchange, and overall fetal development. In the second study (Chapter 3), expression of HIF1A, AHR, and angiogenic factors were characterized in the cyclic and pregnant endometrium at the time of attachment/implantation. Contrary to our hypothesis, the expression of HIF1A, AHR, and angiogenic factors remains low during the attachment/implantation period. Moreover, our results suggest that IFNT may exert a suppressive effect on the expression of molecules of HIF signaling. Understanding the timing and mechanisms governing blood vessel growth, structure, and function in the placenta is crucial for the prevention of placental disorders that impact embryonic health and survival. Although the uterine environment undergoes major immunological adaptations to accommodate the developing embryo, the peripheral immune system is not isolated from pregnancy changes. Hormonal and metabolic signals associated with pregnancy have systemic effects on the immune response in the blood and extrauterine organs. It is generally accepted that systemic immunity must balance tolerance to the developing embryo while also remaining vigilant in eliminating pathogens and threats to pregnancy health. Understanding this delicate immunological balance can support efforts in the prevention of pregnancy loss and complications. In the third study (Chapter 4), we characterized changes in circulating leukocytes during early pregnancy and investigated peripheral immunity differences between lactating cows and heifers. In the first experiments, heifers and cows were studied separately, revealing both similarities and differences in the phenotype of blood leukocytes in response to early pregnancy. In the final experiment, we simultaneously compared samples from heifers and cows, and the results indicated that cows exhibited greater expression of proinflammatory cytokines and molecules associated with leukocyte migration and phagocytosis compared to heifers. Moreover, animals that failed to become pregnant showed altered expression of anti-inflammatory molecules compared to pregnant and cyclic animals. Overall, these findings support the notion that immune responses to early pregnancy differ in heifers and cows, which may contribute to the reduced fertility observed in lactating cows. During our experiments with PBL, we observed that some heifers experienced luteolysis between days 16 and 17 of the estrous cycle, while cows experienced it after day 18. Progesterone primarily regulates cell function via the nuclear progesterone receptor (PGR) and can also signal through membrane-associated receptors of the PAQR and PGRMC family. In cattle, progesterone secretion remains elevated throughout pregnancy, but there is conflicting evidence regarding the presence of PGR in leukocytes of both cattle and humans. In our last study (Chapter 5), we aimed to determine the expression of progesterone and estradiol receptors in bovine peripheral blood leukocytes (PBL) and if their expression was affected by reproductive status, parity, or the day of pregnancy. We also investigated the correlation between steroid hormone concentrations in plasma and the phenotype of blood leukocytes. The results revealed that bovine leukocytes lack PGR during early and mid-pregnancy but express nuclear ESR and membrane PGR (mPGR). Additionally, there was a positive correlation between plasma estradiol and a negative correlation of plasma progesterone with changes in the proportion of myeloid cells and the expression of molecules involved in leukocyte migration during proestrus. Contrary to some published literature, these findings suggest that bovine PBL do not express PGR, and instead, mPGR of the PAQR and PGRMC family may mediate progesterone effects on leukocyte function. In summary, the findings presented in this dissertation have expanded our understanding in several areas: (1) the effects of IFNT and PAG on gene expression in the endometrium and circulating leukocytes, (2) the expression of angiogenic factors in the uterus, (3) the peripheral immune response to early pregnancy in heifers and lactating cows, and (4) the expression of progesterone receptors in immune cells. Our results provide support for the hypothesis that uterine and peripheral immunity is regulated by conceptus and maternal signals to facilitate the establishment of successful pregnancies. The insights gained from this research can help identify immunological factors associated with embryo loss and offer valuable perspectives on the application of strategies to enhance fertility in dairy cattle, other domestic species, and potentially even in humans.

This book was released on 2020-05-01 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The delivery of high quality and equitable care for both mothers and newborns is complex and requires efforts across many sectors. The United States spends more on childbirth than any other country in the world, yet outcomes are worse than other high-resource countries, and even worse for Black and Native American women. There are a variety of factors that influence childbirth, including social determinants such as income, educational levels, access to care, financing, transportation, structural racism and geographic variability in birth settings. It is important to reevaluate the United States' approach to maternal and newborn care through the lens of these factors across multiple disciplines. Birth Settings in America: Outcomes, Quality, Access, and Choice reviews and evaluates maternal and newborn care in the United States, the epidemiology of social and clinical risks in pregnancy and childbirth, birth settings research, and access to and choice of birth settings.

Book Synopsis Recurrent Implantation Failure by : Jason M. Franasiak
Download or read book Recurrent Implantation Failure written by Jason M. Franasiak and published by Springer. This book was released on 2018-04-03 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique text discusses the wide range of causes and pathophysiologic conditions contributing to recurrent implantation failure (RIF) and the current treatment approaches to best approach this challenging patient population. Beginning with a presentation of the mechanism of normal implantation, the physiologic synchrony between embryo and endometrium, and the roles of both gametes and embryos in RIF, the book then examines the various genetic, immune and environmental factors involved. Abnormalities of the hematologic and endocrine system, as well as those of the anatomy and microbiome, are described in detail. Last but no less important, the psychological stress and treatment of patients experiencing RIF is discussed. Assisted reproductive technology (ART) success has increased substantially over the past three decades. However, despite these advances, recurrent implantation failure is still a common issue confronting patients and clinicians, and RIF represents one of the greatest challenges in ART and remains a source of frustration and disappointment for patients, clinicians, and researchers involved in the process. Providing an in-depth investigation into the pathophysiology and biological mechanisms of RIF and its clinical management, this will be an excellent resource for reproductive endocrinologists and infertility specialists.
Book Synopsis In Vitro Fertilization and Embryo Transfer in Primates by : Don P. Wolf
Download or read book In Vitro Fertilization and Embryo Transfer in Primates written by Don P. Wolf and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a genuine honor and a privilege of distinction to provide the foreword for the proceedings that follow. This marvelous symposium reflects the unique qualities of its two principal sponsors. Whenever the Oregon Regional Primate Research Center is involved in matters of science, we see a consistent record of exceptional quality in both the work is unequaled and the people who do it. Likewise, Serono Symposia, USA in assuring a world-class speakers' forum, utterly without taint of commercial influence. The proceedings published herein are a remarkable testimony, not only to the contributors, but to Drs. Brenner, Wolf, Stouffer, and Burnett, who have shepherded its conception, presentation, and publication. Readers will notice immediately one of the universal strengths of this total composition; that is, the diversity of investigational interests among attendees. Presentations on the core topic of primate in vitro fertilization and embryo transfer were joined by specialist presentations in related areas, including human-assisted reproductive technologies, reproductive physiology of the great apes, sperm biology, implantation mechanisms, cryobiology, coculture systems for embryogenesis, micromanipulation technologies, and genetic diagnosis of heritable diseases in the pre embryo. Even though pro-fertility issues understandably dominated this forum, there was significant attention given to fertility-control research, especially the role of primates in this endeavor (more on this subject below).
