Contraception and Pregnancy in Patients with Rheumatic Disease (Paperback, Softcover reprint of the original 1st ed. 2014):... Contraception and Pregnancy in Patients with Rheumatic Disease (Paperback, Softcover reprint of the original 1st ed. 2014)
Lisa R. Sammaritano, Bonnie L. Bermas
R4,228 Discovery Miles 42 280 Ships in 10 - 15 working days

Rheumatic (or systemic autoimmune) diseases disproportionately affect young women: the female-to-male ratio for patients with systemic lupus erythematosus during the reproductive years is approximately 9:1. In the mid- to late-twentieth century, women with rheumatic disease diagnoses were often advised to avoid pregnancy due to fear of disease exacerbation and adverse outcome. In more recent years, many women with rheumatic disease have deferred childbearing until a later age due to active disease or unsafe therapies. However, with advances in rheumatology therapies, obstetric monitoring, and reproductive medicine technologies, increasing numbers of women with rheumatic diseases are pursuing pregnancy. As a result, obstetricians and rheumatologists need to be aware of the current state of knowledge and the recommendations for management of pregnancy in these patients. Contraception and Pregnancy in Patients with Rheumatic Disease explains the basics of contraception, fertility treatment, and pregnancy in rheumatic disease patients and serves as a guide and reference tool for both rheumatologists and OB/GYNs. Most general rheumatologists and OB/GYNs have limited experience in caring for rheumatic disease patients during pregnancy, and many do not have ready access to expert colleagues in this area. This book summarizes the current state of knowledge and presents a general approach for assessment of the rheumatic disease patient considering pregnancy, hormonal contraception or infertility treatment.

R1,987 Discovery Miles 19 870 Ships in 10 - 15 working days

Advances in technology now offer promising solutions to deal with the chronological aging of the cell, tissue or organ to synchronize its existence and its use. This book covers the developments in and benefits of the latest vitrification technology and its extensive applications in reproductive medicine. Protocols of gametes (oocyte and sperm), embryos, blastocysts and ovarian tissue cryopreservation have been reviewed by leaders in the field. In order to address the escalation in cross-border reproductive tourism entailing the transfer of reproductive cells and tissues rather than the patient, the challenges, caution and emerging possibilities of nitrogen vapor shipment of vitrified cells have been discussed. Current perspectives on oocyte banking present the reader with options and solutions to effectively utilize these gametes despite the physiological deterrents.The versatile applications and potential of vitrification of human embryonic stem cells, discussed in the concluding chapter, is an exciting reality offered by vitrification to help overcome numerous stumbling blocks in the management of various disorders.

Oocyte Biology in Fertility Preservation (Paperback, Softcover reprint of the original 1st ed. 2013): S. Samuel Kim Oocyte Biology in Fertility Preservation (Paperback, Softcover reprint of the original 1st ed. 2013)
S. Samuel Kim
R3,292 Discovery Miles 32 920 Ships in 10 - 15 working days

Fertility preservation has become one of the most important and fast growing fields of reproductive medicine. Although there are several strategies for fertility preservation in female, most of them are still considered experimental. It is important to perfect the existing technologies, but also developing new strategies should be actively sought. The future development of fertility preservation strategies should be based on the sound scientific knowledge and principles. One of the main objectives of fertility preservation in females is prevention of oocyte depletion. The mechanisms of oocyte loss and survival in the ovary are complex, which include genetic control both in germ cells and in somatic cells, DNA damage and repair mechanism, apoptosis and autophagy, and other poorly understood molecular mechanisms. To develop clinically effective and safe strategies for fertility preservation, it is essential to know and understand the fundamentals of oocyte and ovarian biology at the molecular level. Thus, the purpose of this edition is to review the current progress in research related to molecular and genetic control of oocyte development that can be applied to fertility preservation. The main topics that are discussed in this publication include molecular signaling mechanisms of oocyte activation and loss, genomic integrity of oocytes, and epigenetics.

R4,449 Discovery Miles 44 490 Ships in 10 - 15 working days

In recent years, the advancing science and increasing availability of assisted reproduction have given new hope to infertile couples. However, the use of IVF and ART has also led to marked increases in the number of multiple-infant live births. This poses a public health concern, as these neonates have a higher rate of pre-term delivery, compromising their survival chances and increasing their risk of lifelong disability. By optimizing the selection of gametes and embryos with high probabilities of implantation, it is possible to reduce the number of embryos transferred and, by extension, the number of high-risk multiple gestations, while maintaining or increasing pregnancy rates. Human Gametes and Preimplantation Embryos: Assessment and Diagnosis provides a broad yet concise overview of established and developing methodologies for assessment of gamete and embryo viability in assisted reproduction. This book elucidates the best practices for precisely selecting viable specimens based on morphology and cleavage rate and covers the spectrum of emerging adjunctive technologies for predicting reproductive potential. The authors present their extensive knowledge of "omics" approaches (genomics, transcriptomics, proteomics, and metabolomics), with unbiased delineation of the associated advantages and potential pitfalls. This valuable clinical resource is well suited to infertility specialists, Ob/Gyn physicians, IVF laboratory technicians, and researchers in the fields of embryology and reproductive medicine.

R1,737 Discovery Miles 17 370 Ships in 9 - 15 working days

The ONLY textbook available on marine mammal physiology, a core topic in Marine Science undergrad teaching Builds on the unique overall theme 'How would you design a marine mammal?' which focuses on what an undergrad student would actually want to know. What would they ask? So rather than "What are the biochemical differences between marine and terrestrial mammals?" the book addresses "How can marine mammals dive for such a long time?" or "How do they stay warm in such cold water?" Organises the Table of Contents into common 'real' student questions. The book thus centres around the point of view of the student. This makes it accessible and student-focused. Consistency across all chapters Provides consistent Power Point slides that teachers can use when they don't know the field well AND that students can use as study guides. Offers Study Questions and future thinking/implications questions. A Driving Question for each chapter is highlighted in a box. A concluding chapter ties up loose ends and consolidates the driving questions from the individual chapters. Contains the contributions of well-respected, prominent scientists in the field. Author bios for each chapter showcase diversity in contributor pool. Focuses on physiological adaptations of marine mammals and connects them with the ecological context, including anthropogenic impacts. Discusses differences that might exist by type of marine mammal, development questions, and behavioral issues.

Developmental Juvenile Osteology was created as a core reference text to document the development of the entire human skeleton from early embryonic life to adulthood. In the period since its first publication there has been a resurgence of interest in the developing skeleton, and the second edition of Developmental Juvenile Osteology incorporates much of the key literature that has been published in the intervening time. The main core of the text persists by describing each individual component of the human skeleton from its embryological origin through to its final adult form. This systematic approach has been shown to assist the processes of both identification and age estimation and acts as a core source for the basic understanding of normal human skeletal development. In addition to this core, new sections have been added where there have been significant advances in the field.

determined by an inability to move in response to touch. C. elegans develop through four larval stages following hatching and prior to adulthood. Adult C. elegans are reproductive for about the rst week of adulthood followed by approximately two weeks of post-reproductive adulthood prior to death. Life span is most commonly measured in the laboratory by maintaining the worms on the surface of a nutrie- agar medium (Nematode Growth Medium, NGM) with E. coli OP50 as the bacterial food source (REF). Alternative culture conditions have been described in liquid media; however, these are not widely used for longevity studies. Longevity of the commonly used wild type C. elegans hermaphrodite (N2) varies ? from 16 to 23 days under standard laboratory conditions (20 C, NGM agar, E. coli OP50 food source). Life span can be increased by maintaining animals at lower ambient temperatures and shortened by raising the ambient temperature. Use of a killed bacterial food source, rather than live E. coli, increases lifespan by 2-4 days, and growth of adult animals in the absence of bacteria (axenic growth or bac- rial deprivation) increases median life span to 32-38 days [3, 23, 24]. Under both standard laboratory conditions and bacterial deprivation conditions, wild-derived C. elegans hermaphrodites exhibit longevity comparable to N2 animals [25].

The world's population is growing at an unsustainable rate. From a baseline ?gure of one billion in 1800, global population is predicted to exceed nine billion by 2050 and 87. 8% of this growth will be localized in less developed countries. Such uneven population growth will yield a harvest of poverty, malnutrition, disease and en- ronmental degradation that will affect us all. Amongst the complex mixture of political, social, cultural and technological changes needed to address this issue, the development of improved methods of fertility regulation will be critical. The inadequacy of current contraceptive technologies is indicated by recent data s- gesting that the contraceptive needs of over 120 million couples go unmet every year. As a direct consequence of this de?cit 38% of pregnancies are unplanned and more than 50% end in an abortion, generating a total of 46 million abortions per annum particularly among teenagers. If safe, effective contraceptives were ava- able to every couple experiencing an unmet family planning need, 1. 5 million lives would be saved each year (UNFPA 2003). Progress in contraceptive technology should not only generate more effective methods of regulating fertility, but should also provide a range of methods to meet the changing needs of the world's population. Contraceptive practice was revo- tionized in 1960 in the US and 1961 in Europe by the introduction of the oral contraceptive pill by Gregory Pincus, MC Chang and colleagues, based on fun- mental hormone research conducted in Germany.
