The investigation and management of infertility has progressed
radically since the advent of in vitro fertilization. It has ceased
to be the province of the gynecologist alone, and often requires
the co-operation of gynecologists, andrologists, endocrinologists,
embryologists, geneticists, general scientists, psychologists,
radiologists, nurses, ultrasonographers, social workers, medical
administrators, and lawyers. Many of these do not have a medical
background and fewer still have knowledge of the gynecological
terms which are still in predominant use. Furthermore, scientific
advances have led to the introduction of techniques and terms
unfamiliar to the non-scientist, including the gynecologist. This
dictionary of reproductive medicine, the first of its kind, has
been conceived to address the concerns of all of these groups.
The success of Assisted Reproductive Technology is critically
dependent upon the use of well optimized protocols, based upon
sound scientific reasoning, empirical observations and evidence of
clinical efficacy. Recently, the treatment of infertility has
experienced a revolution, with the routine adoption of increasingly
specialized molecular biological techniques and advanced methods
for the manipulation of gametes and embryos. This textbook -
inspired by the postgraduate degree program at the University of
Oxford - guides students through the multidisciplinary syllabus
essential to ART laboratory practice, from basic culture techniques
and micromanipulation to laboratory management and quality
assurance, and from endocrinology to molecular biology and research
methods. Written for all levels of IVF practitioners, reproductive
biologists and technologists involved in human reproductive
science, it can be used as a reference manual for all IVF labs and
as a textbook by undergraduates, advanced students, scientists and
professionals involved in gamete, embryo or stem cell biology.
Selecting the best embryo to transfer to the uterus is key to
successful in vitro fertilization (IVF). A huge amount of research
has been devoted to this topic and there are numerous methods used,
from simple morphological assessment to molecular biological
techniques to assess the genome and metabolism of the newly
fertilized embryo. For many of these techniques, an adequate
evidence base is lacking, and expert opinion is valuable. Clinical
imperatives require ranking all embryos in a cohort according to
their viability, thereby enabling the selection of the best embryo
to optimize live birth outcome: a key indicator used to measure and
rate IVF Clinics worldwide. This clear and informative manual will
provide embryologists and clinicians with an overview of the tools
now available to assist in embryo selection, as well as evidence
for their efficacy and safety and the broader considerations that
must underlie these important clinical decisions.
This comprehensive review of the factors that affect the harvesting
and preparation of oocytes and the management of embryos will allow
practitioners to make evidence-based decisions for successful IVF.
The book reviews and re-considers the value of strategies and
outcomes in the management of fertility and conception rates,
centred on the production of oocytes, and successful development of
the embryo. Authored by leading experts in the field, chapters
engage with treatments and strategies that affect the production of
oocytes and embryos, optimizing outcomes in the management of
female fertility, conception rates, and live births. This vital
guide covers controlled ovarian hyperstimulation, the role of AMH
in determining ovarian reserve, and primary stimulation agents and
the use of adjuncts. Integral for all clinicians and embryologists
working in reproductive medicine units, readers are provided with
evidence-based, comprehensive advice and review of all factors
affecting the management of oocytes and the embryo that are vital
for successful IVF cycles.
Asserting that there are many more organic codes in nature than just the genetic code, Marcello Barbieri states that the existence of these codes and their corresponding organic memories can be used to explain the key steps in the evolutionary history of life. With major events corresponding to the appearance of new codes, the organic codes and their corresponding organic memories can also shed new light on the problems of epigenesis and how embryos generate their own complexity.
Leading gender and science scholar Sarah S. Richardson charts the
untold history of the idea that a woman's health and behavior
during pregnancy can have long-term effects on her descendants'
health and welfare. The idea that a woman may leave a biological
trace on her gestating offspring has long been a commonplace folk
intuition and a matter of scientific intrigue, but the form of that
idea has changed dramatically over time. Beginning with the advent
of modern genetics at the turn of the twentieth century, biomedical
scientists dismissed any notion that a mother-except in cases of
extreme deprivation or injury-could alter her offspring's traits.
Consensus asserted that a child's fate was set by a combination of
its genes and post-birth upbringing. Over the last fifty years,
however, this consensus was dismantled, and today, research on the
intrauterine environment and its effects on the fetus is emerging
as a robust program of study in medicine, public health,
psychology, evolutionary biology, and genomics. Collectively, these
sciences argue that a woman's experiences, behaviors, and
physiology can have life-altering effects on offspring development.
Tracing a genealogy of ideas about heredity and maternal-fetal
effects, this book offers a critical analysis of conceptual and
ethical issues-in particular, the staggering implications for
maternal well-being and reproductive autonomy-provoked by the
striking rise of epigenetics and fetal origins science in
postgenomic biology today.
Developmental biologists have been driven to investigate growth
factor signaling in embryos in order to understand the regulatory
mechanisms underlying a given developmental process. Thus, it is
critical to explore the technical methods and experimental designs
for growth factor signaling in embryos.
Focusing on specific pathways or pathway components, Analysis of
Growth Factor Signaling in Embryos provides the methods and
guidelines for experimental design to study major aspects of cell
signaling in vertebrate embryos. The book covers a broad range of
topics in signaling and a variety of current model organisms.
Section I explores specific signaling pathways or pathway
components. In this section, some chapters highlight the
biochemistry of signaling pathways during development, which is
often distinctive from that observed in cell culture systems.
Section II discusses ionic regulatory mechanisms and the two
chapters in Section III examine ways of investigating gene
regulation in response to extracellular signals. Finally, Section
IV addresses emerging strategies that facilitate integrated
analyses of cell signaling" in vivo" in embryonic systems.
Featuring contributions from expert researchers, Analysis of
Growth Factor Signaling in Embryos will provide a foundation for
further explorations of the cellular regulatory mechanisms
governing vertebrate embryonic development.
Biopolitics and posthumanism have been passe theories in the
academy for a while now, standing on the unfashionable side of the
fault line between biology and liberal thought. These days, if
people invoke them, they do so a bit apologetically. But, as Ruth
Miller argues, we should not be so quick to relegate these terms to
the scholarly dustbin. This is because they can help to explain an
increasingly important (and contested) influence in modern
democratic politicsthat of nostalgia. Nostalgia is another somewhat
embarrassing concept for the academy. It is that wistful sense of
longing for an imaginary and unitary past that leads to an
impossible future. And, moreover for this book, it is ordinarily
considered bad for democracy. But, again, Miller says, not so fast.
As she argues in this book, nostalgia is the mode of engagement
with the world that allows thought and life to coexist,
productively, within democratic politics. Miller demonstrates her
theory by looking at nostalgia as a nonhuman mode of thought,
embedded in biopolitical reproduction. To put this another way, she
looks at mass democracy as a classically nonhuman affair and
nostalgic, nonhuman reproduction as the political activity that
makes this democracy happen. To illustrate, Miller draws on the
politics surrounding embryos and the modernization of the Turkish
alphabet. Situating this argument in feminist theories of
biopolitics, this unusual and erudite book demonstrates that
nostalgia is not as detrimental to democratic engagement as
scholars have claimed.
