  1. Assisted Reproductive Technology in Iran: The First National Report on Centers, 2011

    PubMed Central

    Abedini, Mehrandokht; Ghaheri, Azadeh; Omani Samani, Reza

    2016-01-01

    Background: Due to the worldwide increase in infertility, it is both necessary and important to have assisted reproductive technology (ART) registries. In Iran, donation and surrogacy programs are approved by decrees from religious scholars. ART has been used since 1984 in Iran and the first Iranian infant conceived by gamete intra-fallopian transfer (GIFT) was born in 1989. This report, however, is the first national report on Iranian ART centers. Materials and Methods: This cross-sectional study, conducted under the supervision of the Iranian Ministry of Health, presented a summary of the numbers and percentages of centers that provided infertility services in Iran, as well as the status of ART in Iran during 2011. Results: A total of 52 centers reported treatment cycles and performed approximately 29000 intrauterine insemination (IUI), in addition to 35000 in vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI) cycles. Conclusion: Iran has considerable potential to provide IVF services for both Iranians as well as other nationalities throughout the region. This proves the need for a national center that will implement a registry system. PMID:27695610

    ... Rowland is a social scientist and a radical feminist, and she has undertaken the task of making readers think twice about reproductive technologies. If a reader isn't thinking twice, it will not do to blame it on Rowland and the shortcomings of her book. She has a good deal to say that is extremely important and that needs to be considered by anyone who is interested in the moral issues, in general, and the issues for women and children, in particular, that are raised by the new and emerging reproductive technologies. Her book should be widely read. And it should generate the worries it is written to generate. PMID:11644539

    2015-12-01

    The human microbiome has gained much attention recently for its role in health and disease. This interest has come as we have begun to scratch the surface of the complexity of what has been deemed to be our "second genome" through initiatives such as the Human Microbiome Project. Microbes have been hypothesized to be involved in the physiology and pathophysiology of assisted reproduction since before the first success in IVF. Although the data supporting or refuting this hypothesis remain somewhat sparse, thanks to sequencing data from the 16S rRNA subunit, we have begun to characterize the microbiome in the male and female reproductive tracts and understand how this may play a role in reproductive competence. In this review, we discuss what is known about the microbiome of the reproductive tract as it pertains to assisted reproductive technologies.

    The progress achieved during the last 25 years in the assisted reproductive technology field has been phenomenal. Many countries currently practice genetic material donation, human embryo cryopreservation, selective embryo reduction, preimplantation genetic diagnosis, and surrogacy. While embryo research and therapeutic cloning are carried out only in a few centers, thus far human cloning has been universally condemned. Nonetheless, the rapid evolution and progress of these various techniques of assisted reproduction has opened a Pandora's box of ethical issues that must be urgently addressed.

    Are there any ethical concerns about reproductive technologies that are specific or unique to developing countries? Three ethical concerns often mentioned specifically in regard to developing countries are (1), the "overpopulation argument"; (2) the limited resources argument; and (3) the ethical problem of poorly trained practitioners offering their services to unsuspecting and uninformed infertile individuals or couples. Each argument is explored in some detail, with the conclusion that ethical problems do, in fact, exist but are not unique to developing countries. Nevertheless, the difficulties relating to reproductive technologies are likely to be greater in developing countries than in developed ones because of limited resources and a larger number of poor people residing there.

    1987-06-01

    As part of a Hastings Center Report series of six articles on reproductive technologies around the world, three Japanese scholars report on the situation in their country. At present, artificial insemination and in vitro fertilization are offered to infertile married couples, and research is performed on early embryos up to 14 days after fertilization. Neither surrogate mothers nor donated gametes are used in Japan. Bai, Shirai, and Ishii identify several issues that they believe merit further public debate, among them the legal status of AID children, the experimental nature of in vitro fertilization, genetic manipulation of embryos, and gender selection. They summarize the findings of four opinion surveys that show a lack of consensus among the Japanese on the acceptability of reproductive technologies, which in the words of the authors "create a tension and a link between traditional belief and contemporary practice."

  10. Possibilities with today's reproductive technologies.

    PubMed

    Johnson, S K

    2005-08-01

    Reproductive efficiency is critical to economic viability for cow/calf producers; however, very few producers take advantage of available reproductive technologies that can increase profitability. Today, more opportunities are available for producers who want to capture value from known genetics. Through the use of artificial insemination (AI), the average producer has access to a wide range of high-accuracy sires that can be selected to match production goals. Systems to synchronize estrus and ovulation can now produce pregnancy rates to a single fixed-timed AI that are 10-15% greater than those of the previous generation. Increased age and weight of calves at weaning is sufficient in some situations to pay for the cost of synchronization and AI. As a result of synchronization, more cows calve early the next year and in subsequent years of synchronization. The breeding season can be shortened without reducing end-of-season pregnancy rates, since synchronized cows have one more chance to conceive than unsynchronized cows in a 22-25 day interval. Cow nutrition can be more economically and precisely managed with a shorter breeding period. Producers that establish AI programs now will be prepared to take advantage of newly identified superior genetics or other technologies, e.g. sexed semen, when they become available. Trends towards more value-based marketing and improvements in pregnancy rates from synchronization systems, make this a key time to be aware of the possibilities using reproductive technologies.

  13. Center for Healthcare Technologies

    Carrano, A.V.

    1994-03-01

    In the U.S., we now spend about 13% of the gross domestic product (CDP) on healthcare. This figure represents nearly $3000 per year per man, woman, and child. Moreover, this expenditure is projected to grow to about 20% of the GDP by the year 2000. Medical research and development accounts for only about 3% of national healthcare spending, and technology development represents only a small fraction of that 3%. New technologies that are far more cost-effective than previous ones - such as minimally invasive surgical procedures, advanced automated diagnostics, and better information systems - could save the nation billions of dollars per year to say nothing of the potential reductions in pain and suffering. A center is described that will coordinate ongoing Laboratory research aimed at developing more cost-effective tools for use by the healthcare community. The new Center for Healthcare Technologies will have many long-term benefits for the region and the nation.

    Epigenetic modification controls gene activity without changes in the DNA sequence. The genome undergoes several phases of epigenetic programming during gametogenesis and early embryo development, coinciding with assisted reproductive technologies (ART) treatments. Imprinting disorders have been associated with ART techniques, but disentangling the influence of the ART procedures per se from the effect of the reproductive disease of the parents is a challenge. Epidemiological human studies have shown altered birthweight profiles in ART compared with spontaneously conceived singletons. Conception with cryopreserved/thawed embryos results in a higher risk of large-for-gestational-age babies, which may be due to epigenetic modification. Further animal studies have shown altered gene expression profiles in offspring conceived by ART related to altered glucose metabolism. It is controversial whether human adolescents conceived by ART have altered lipid and glucose profiles and thereby a higher long-term risk of cardiovascular disease and diabetes. This commentary describes the basic concepts of epigenetics and gives a short overview of the existing literature on the association between imprinting disorders, epigenetic modification and ART.

  15. Ultrasound in assisted reproductive technology.

    PubMed

    Porter, Misty Blanchette

    2008-05-01

    Transvaginal ultrasound-guided oocyte retrieval is the gold standard for in vitro fertilization (IVF) treatment. Despite its relative safety, oocyte retrieval is associated with risk to the adjacent pelvic organs, bleeding, and pelvic infection. The embryo transfer (ET) procedure is considered a crucial step in an IVF cycle. The success of the ET is dependent upon multiple factors including embryo quality, proper endometrial receptivity, and the technique by which the embryos are transferred. Optimizing the technique of ET would therefore provide the best chance for pregnancy. No standard evidence-based protocol exists, but ET with ultrasound guidance has been shown to significantly increase the chance of embryo implantation, an ongoing pregnancy, and a live birth and to improve the ease of transfer. Identifying appropriate ultrasound-guided simulation training techniques in ET would ensure adequate fellowship training without affecting the outcome of assisted reproductive technology cycles.

    Seidel, George E

    2015-01-01

    A plethora of assisted reproductive technologies (ARTs) have come into routine use over the past half century. Some of these procedures were used much earlier experimentally. For example, Spallanzani performed artificial insemination in the dog in the late 1700s, and Heape did successful embryo transfer in the rabbit in 1890. Truly revolutionary tools and concepts important for ART occur at approximately half-decade intervals, for example, recombinant DNA procedures, transgenic technology, somatic cell nuclear transplantation, the polymerase chain reaction, and microRNAs. Similarly, obvious technologies sometimes take decades to come into practical use, such as sexing sperm and in vitro fertilization. I have categorized ARTs into five somewhat arbitrary categories in terms of perceived difficulty and feasibility: (a) when the seemingly possible turns out to be (essentially) impossible, e.g., homozygous, uniparental females; (b) when the seemingly impossible becomes possible, e.g., cryopreservation of embryos and transgenesis; (c) when the seemingly difficult turns out to be relatively easy, e.g., cryopreservation of sperm; (d) when the seemingly easy turns out to be difficult in key species, e.g., in vitro fertilization; and (e) when the seemingly difficult remains difficult, e.g., making true embryonic stem cells. The adage that "it is easy when you know how" applies repeatedly. The boundaries between what appears impossible/possible and difficult/easy change constantly owing to new tools and insights, one of the more important lessons learned. ARTs frequently are synergistic with each other. For example, somatic cell nuclear transplantation has made many kinds of experiments feasible that otherwise were impractical. Another example is that sexing sperm is useless for application without artificial insemination or in vitro fertilization. ARTs frequently are perceived as neat tricks and stimulate further thinking. This is useful for both teaching and research. PMID

    The Department of Energy, Golden Field Office, awarded a grant to the UNLV Research Foundation (UNLVRF) on August 1, 2005 to develop a solar and renewable energy information center. The Solar Technology Center (STC) is to be developed in two phases, with Phase I consisting of all activities necessary to determine feasibility of the project, including design and engineering, identification of land access issues and permitting necessary to determine project viability without permanently disturbing the project site, and completion of a National Environmental Policy Act (NEPA) Environmental Assessment. Phase II is the installation of infrastructure and related structures, which leads to commencement of operations of the STC. The STC is located in the Boulder City designated 3,000-acre Eldorado Valley Energy Zone, approximately 15 miles southwest of downtown Boulder City and fronting on Eldorado Valley Drive. The 33-acre vacant parcel has been leased to the Nevada Test Site Development Corporation (NTSDC) by Boulder City to accommodate a planned facility that will be synergistic with present and planned energy projects in the Zone. The parcel will be developed by the UNLVRF. The NTSDC is the economic development arm of the UNLVRF. UNLVRF will be the entity responsible for overseeing the lease and the development project to assure compliance with the lease stipulations established by Boulder City. The STC will be operated and maintained by University of Nevada, Las Vegas (UNLV) and its Center for Energy Research (UNLV-CER). Land parcels in the Eldorado Valley Energy Zone near the 33-acre lease are committed to the construction and operation of an electrical grid connected solar energy production facility. Other projects supporting renewable and solar technologies have been developed within the energy zone, with several more developments in the horizon.

  1. Reproductive technology in animal production.

    PubMed

    Shelton, J N

    1990-09-01

    Research into physiology and embryology has provided a basis for the development of technologies that increase productivity of farm animals through enhanced control of reproductive function. Progestagens, alone or in combination with luteolysins, are used to control the time of oestrus in cattle, sheep and pigs, thus permitting better use of artificial insemination, providing synchronised recipients for embryos and facilitating management strategies. Treatment with progestagens and pregnant mare serum gonadotrophin (PMSG) or with gonadotrophin releasing hormone induces breeding activity in sheep and goats before the commencement of the breeding season and reduces the duration of postpartum anoestrus in cattle. In pigs, gonadotrophins are used to hasten puberty in gilts, control the time of oestrus in sows and gilts and reduce the interval between farrowing and oestrus. Implants of melatonin hasten the onset of the breeding season in sheep and goats. Success in increasing litter size in sheep and cattle with PMSG has been limited because of the large variation in response between animals. Likewise, immunisation against steroids has not given consistent results. Immunisation against inhibin appears to offer the possibility of increasing farm animal fecundity. Induction of twinning in cattle by embryo transfer is practicable, and recent developments suggest that in vitro fertilisation may provide a source of embryos for this purpose. Real-time ultrasonic scanning has proved to be a reliable method for diagnosing pregnancy in small ruminants and pigs. The identification of pregnancy-specific proteins in cattle and sheep may provide a cheap and practical serological test for pregnancy in these species. Partial segregation of spermatozoa into X- and Y-bearing components has been reported, but the method is not yet practicable for use in conventional artificial insemination of farm animals. The sex of bovine and ovine embryos can be determined reliably by DNA probes

    The recent development of genomic selection induces dramatic changes in the way genetic selection schemes are to be conducted. This review describes the new context and corresponding needs for genomic based selection schemes and how reproductive technologies can be used to meet those needs. Information brought by reproductive physiology will provide new markers and new improved phenotypes that will increase the efficiency of selection schemes for reproductive traits. In this context, the value of the reproductive techniques including assisted embryo based reproductive technologies (Multiple Ovaluation Embryo Transfer and Ovum pick up associated to in vitro Fertilization) is also revisited. The interest of embryo typing is discussed. The recent results obtained with this emerging technology which are compatible with the use of the last generation of chips for genotype analysis may lead to very promising applications for the breeding industry. The combined use of several embryo based reproductive technologies will probably be more important in the near future to satisfy the needs of genomic selection for increasing the number of candidates and to preserve at the same time genetic variability.

    In modern agriculture, assisted reproductive technologies are being used for out of season oestrus induction, enhancement of reproductive performance and genetic improvement. In addition, they can have substantial contribution in preservation of endangered species or breeds, as well as in eradication programs of various diseases. While their applications are widespread in cattle, in small ruminants it is almost restricted to artificial insemination. The main limitations of a wider application in small ruminants are the naturally occurring anoestrus period, the variability of response to superovulatory treatments, the fertilisation failure and the need of surgery for collection and transfer of gametes and embryos. Nonetheless, during the last 30 years, considerable progress has been made in sheep and goat embryo technologies, especially in the fields of oestrus synchronisation, superovulation and in vitro embryo production. This paper reviews the status of assisted reproductive technologies in sheep, analysing the prospects offered by recent advances in in vivo and in vitro embryo production from mature and juvenile lambs.

Analysis of the data sourced from manual searches of bibliographies from key articles showed that this technology in KSA is practiced in a strictly religious manner and certain aspects of the technology are completely forbidden. It further showed that lack of an official government in-vitro fertilization (IVF) registry to gather information on the activities of IVF clinics has limited the data available for international comparisons. Sharing information internationally could allow religiously concerned infertile couples to have access to the reproductive services in the Kingdom. It would further improve the quality of care, enhance certain techniques like in-vitro maturation and experimentation on embryos, by providing resources that are currently unavailable, keeping in view the religious beliefs and avoiding conflicts.

    The convergence of the fields of clinical genetics and assisted reproductive technologies is providing couples at risk for transmitting a genetic disorder to their children with new reproductive alternatives. The ability to test the preimplantation embryo for genetic anomalies, sort for X- and Y-bearing sperm, and improve genetic screening of gamete donors and couples at risk for a genetic disorder, are examples of these alternatives. The scope of nursing practice will be affected by the integration of these technologies into the health care offered to consumers. Opportunities also will exist for nurses to assist in the redefinition of health and illness that will be the serendipitous outcome of these scientific advances. PMID:7965254

As a result, there is a strong interest in the factors that affect the efficient production of viable embryos and offspring in the pig using either in vivo or in vitro production methods. The application of assisted reproductive technologies (ART) has the potential to increase reproductive efficiency in livestock. These technologies include, but are not limited to: artificial insemination (AI), fixed-time AI, embryo transfer, cryopreservation of sperm/oocytes/embryos, in vitro fertilization and somatic cell nuclear transfer (cloning). However, the application of ART is much less efficient in the pig than in many other mammalian species such as cattle. Until recently, the underlying causes of these inefficiencies have been difficult to study, but advances in molecular biology techniques for studying gene expression have resulted in the availability of a variety of options for gene expression profiling such as microarrays, and next generation sequencing technologies. Capitalizing on these technologies the effects of various ARTs on the porcine embryonic transcriptome has been determined and the impact on the related biological pathways and functions been evaluated. The implications of these results on the efficiency of ARTs in swine, as well potential consequences for the developing embryo and resulting offspring, are reviewed.

    The Vatican Instruction on reproductive technologies and the OTA report, Infertility, both use "rights" language to advance quite different views of the same subject matter. The former focuses on the rights and welfare of the embryo, and the protection of the family, while the latter stresses the freedom and rights of couples. This essay uses the work of Alasdair MacIntyre and Jeffrey Stout to consider the different traditions grounding these definitions of rights. It is proposed that a potentially effective mediating language could be that of "human nature", and argued that donor methods raise more serious moral objections than homologous ones. PMID:2691613

    NASA's Kennedy Space Center (KSC) is developing as a world-class Spaceport Technology Center (STC). From a process engineering (PE) perspective, the facilities used for flight hardware processing at KSC are NASA's premier factories. The products of these factories are safe, successful shuttle and expendable vehicle launches carrying state-of-the-art payloads. PE is devoted to process design, process management, and process improvement, rather than product design. PE also emphasizes the relationships of workers with systems and processes. Thus, it is difficult to speak of having a laboratory for PE at KSC because the entire facility is practically a laboratory when observed from a macro level perspective. However, it becomes necessary, at times, to show and display how KSC has benefited from PE and how KSC has contributed to the development of PE; hence, it has been proposed that a Process Engineering Technology Center (PETC) be developed to offer a place with a centralized focus on PE projects, and a place where KSC's PE capabilities can be showcased, and a venue where new Process Engineering technologies can be investigated and tested. Graphics for showcasing PE capabilities have been designed, and two initial test beds for PE technology research have been identified. Specifically, one test bed will look into the use of wearable computers with head mounted displays to deliver work instructions; the other test bed will look into developing simulation models that can be assembled into one to create a hierarchical model.

    History of marital infertility is as long as history of human :ivilization. Becoming aware about the importance of procreation, as well as the problems with which people may confront, has been the subject of interest since the moment of the first human community creation. Historically, each stage of social development, hence the development of science, has carried within itself certain findings more or less acceptable from today's point of view. The development of human awareness and acquisition of findings based on empirical evidence have contributed to understanding and solution of the problem which was considered to be a result of force majeure until that moment and therefore could not be influenced. This paper deals with the previously mentioned issues through the review of historical development of assisted reproductive technology and its importance. The authors' intention was to present the developmental road of assisted reproductive technology through history succinctly with a special emphasis on the moments which have been of the crucial importance and which have marked certain stages of its development.

    The choice of adoption over genetic parenthood was investigated in 105 women retrospectively by questionnaire. Participants were divided into four groups: female/male subfertility; female subfertility; male subfertility; and female/male fertility. Half the sample (59/105) answered the question about the importance of a genetic link. Women who failed to adopt thought a genetic link was important, as did those who were less likely to disclose alternative reproductive conceptions to their child. First thoughts following diagnosis were more focused and actions more centered on adoption in the female/male subfertile group compared to the other groups. Communication of the child's origins was least prevalent in the female/male subfertile group, followed by the male subfertile group, although all groups would disclose adoption. The choice of adoption was determined by a number of factors, not all associated with infertility resolution. Although it is unlikely that resolution to infertility can be achieved in any population attempting to overcome infertility, the cognitive dissonance identified in this population is likely to be generalizable to those choosing other options to overcome infertility. Cultural and counselling acknowledgement of postmodern family theory principles is likely to ease cognitive consistency regarding the status of adoptive familyhood, and dispel the importance of reproductive options emphasizing a genetic link.

    1. Reproductive ability requires both endocrine and behavioural components. 2. Most reproductive behaviour is dependent upon the presence of sufficient circulating concentrations of the gonadal steroids, which in turn are synthesised and secreted in individuals who are in good reproductive condition. Mating behaviour patterns are thus not only essential for reproduction, but can provide excellent indices of the reproductive ability of an individual. 3. A number of factors can suppress or enhance reproductive behaviour in poultry, including management practices, flock social interactions, environmental variables, stressors, and disease. 4. Aspects of the regulation of reproductive behaviour and the endocrine control of reproductive processes in the male and in the female are reviewed in this paper. 5. An understanding of the impact of social and environmental stressors on reproductive physiology and behaviour is extremely important, both in order to improve breeding efficiency in natural mating systems and to facilitate the most effective application of artificial insemination technology.

  6. Commentary on women-centered reproductive health services.

    PubMed

    Toro, O L

    1989-01-01

    From women's perspectives, the primary principles of a reproductive health framework in the developing world are as follows: Family planning is a basic human right to which all human beings are entitled. Provision of family planning services must be comprehensive, including safe and low cost methods, freedom of choice about both contraception and pregnancy termination, timely and honest information, privacy and confidentiality, individual needs assessment, and counseling of women, men or the couple. Wide contraceptive choice requires more research on methods that are less invasive of women's anatomy and physiology and more supportive of women's control of their own bodies. These parameters of quality care in family planning must be centered on women's needs, desires and expectations. The concept of conscious contraception implies an attitude of conscious sexuality. When a woman accepts that sexual gratification independent of reproduction is a legitimate right, she is better prepared to engage in the pursuit of her own health and happiness. If family planning programs do not include sexuality as a key issue to discuss with clients, all long-term strategies will fall short in modifying people's attitudes, especially women's reluctance to contracept. Sexual and reproductive health includes emotional health. As Dr. Sai points out, the effects of underdevelopment and poverty strike women in dramatic ways, and quite often all the pressures to which they are exposed lead to precarious emotional health. They become victims of violence and repeat the cycle of violence with their children. We, as advocates of sexual and reproductive rights, must also consider the psychological and emotional implications of sexuality and reproduction, and learn to deal with them in our clinics and services.(ABSTRACT TRUNCATED AT 250 WORDS)

    2004-07-01

    Assisted reproduction technologies (ART) are reviewed with special emphasis on goat genetic improvement programs. Estrous synchronization and artificial insemination are the most commonly used ART worldwide because of their simplicity and excellent cost/benefit, especially when proven sires are used. Multiple ovulation and embryo transfer (MOET) has not become widely used due to its unpredictability. In vitro embryo production using oocytes collected by laparoscopy from valuable donors has the potential to improve the results obtained from MOET and expand its applications (for example, using prepubertal donors). However, the costs and inefficiencies of the system might restrict its use to special situations. Finally, transgenesis and cloning are expected to have a significant impact on the future genetic improvement of livestock. However, because of low efficiencies and high costs, their present use is restricted to applications with high returns such as the production of recombinant proteins of pharmaceutical and biomedical interest.

    Infertile women suffer chronic stress, which may negatively impact their parenting relationships if they later succeed in bearing children. The purpose of this study was to explore the parenting stress of mothers attending assisted an reproductive program and to compare it with the parenting stress of mothers with natural pregnancies. A purposive sampling method was used to recruit 54 mothers attending an In Vitro Fertilization/Embryo Transfer and Tubal Embryo Transfer program at an infertility center in central Taiwan. Three instruments were used to collect data: the Demographic Data Form, Parenting Stress Index-Short Form and Family Adaptation Partnership Growth Affective Relation Index. The data were analyzed by descriptive and inferential statistical methods. (1) The results indicated that the highest average score in parenting stress for mothers receiving reproductive technology was for "parental distress". These results revealed that the main source of parenting stress was their parental role. (2) Family function varied significantly with parenting stress. (3) Parenting stress was significantly greater in mothers with natural pregnancy than in mothers attending the assisted reproductive program. Recommendations for clinical application and future research are also made. The implications of the study may be used to assist infertile women in coping with parenting roles. Furthermore, a qualitative study is suggested to understand the factors which cause parenting stress.

    What motivates the global movements of infertile people searching for assisted reproductive technologies (ARTs)? In this article, we attempt to answer this question by exploring infertile patients' practices of so-called "fertility tourism." Based on ethnographic research carried out with nearly 300 infertile travelers in two major ART centers--one in the global hub of the United Arab Emirates and the other at a major East Coast Ivy League university--we examine a diverse set of reasons for reproductive travel. We argue that reproductive "tourism" should be reconceptualized as reproductive "exile" in that infertile couples feel barred from accessing ARTs in their home countries. Listening to reproductive travel stories is key to understanding infertile couples' transnational "quests for conception." Stories of two couples, one from Lebanon and one from Italy, demonstrate the poignancy of these quests and begin to shed light on the complex calculus of factors governing this global movement of reproductive actors.

    The U.S. is the largest producer of mining products in the world. In 2011, U.S. mining operations contributed a total of $232 billion to the nation’s GDP plus $138 billion in labor income. Of this the coal mining industry contributed a total of $97.5 billion to GDP plus $53 billion in labor income. Despite these contributions, the industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Originally set up by Virginia Tech and West Virginia University, CAST is now a five-university consortium – Virginia Tech, West Virginia University, University of Kentucky, University of Utah and Montana Tech, - that is supported through U.S. DOE Cooperative Agreement No. DE-FE0000699, Center for Advanced Separation Technology. Much of the research to be conducted with Cooperative Agreement funds will be longer term, high-risk, basic research and will be carried out in two broad areas: Advanced Pre-Combustion Clean Coal Technologies and Gas-Gas Separations. Distribution of funds is handled via competitive solicitation of research proposals through Site Coordinators at the five member universities. These were reviewed and the selected proposals were forwarded these to the DOE/NETL Project Officer for final review and approval. The successful projects are listed below by category, along with abstracts from their final reports.

    Standardized, high-quality training in reproductive endocrinology, infertility, and assisted reproductive technologies (REI-ART) faces challenges owing to the high-tech nature of ART and the important country-to-country differences in clinical practice and regulations overseeing training. Moreover, while the training capacity of the classical by-fellowship training platforms is shrinking, an increasing demand for REI-ART specialists is coming from emerging countries. To meet this expanding need for REI-ART specialists, we propose a novel by-network model linking a reference training center to satellite practical training sites. Simulation should be used more extensively to achieve competency before initiating live clinical experience, analogous to the highly effective training systems that have been used in aviation for decades. Large ART databases that exist because of obligations to report ART activity and results constitute unique yet so far untapped sources for developing by-scenario simulation training models. Online training materials incorporating these state-of-the-art information technology tools could be developed as a means of fulfilling training needs worldwide.

  16. Reproduction of ON-center and OFF-center self-rotations.

    PubMed

    2005-06-01

    In self-rotation reproduction tasks, subjects appear to estimate the displacement angle and then reproduce this angle without necessarily replicating the entire temporal velocity profile. In contrast, subjects appear to reproduce the entire temporal velocity profile during linear motion stimulating the otoliths. To investigate what happens during combined rotation and translation, we investigated in darkness the central processing of vestibular cues during eccentric rotation. Controlling a centrifuge with a joystick, nine healthy subjects were asked to reproduce the angle of the previously imposed rotation. Rotations were either ON-center, or 50 cm OFF-center with inter-aural centripetal acceleration. Rotation duration was either variable (proportional to the traveled angle), or constant. We examined whether the stimulation of the otoliths during OFF-center rotation changes self-rotation reproduction, and whether rotation duration is processed differently by the nervous system with and without otolith stimulation. As postulated, the subjects indeed reproduced more closely the stimulus velocity profile when OFF-center. But the primary result is that the additional supra-threshold linear acceleration cues, measured by the otoliths, did not improve performance. More specifically, to our surprise, the ability to reproduce rotation angle degraded slightly in the presence of additional information from the otolith organs, with the linear acceleration cues appearing to interfere with the reproduction of movement duration.

    Collier, Abby C.; Miyagi, Shogo J.; Yamauchi, Yasuhiro; Ward, Monika A.

    2009-01-01

    The placenta plays a vital role in pregnancy by facilitating steroid passage from maternal to fetal circulation and/or direct production of hormones. Using a murine model, we demonstrated the differences in placental steroid metabolism between pregnancies conceived naturally and with assisted reproduction technologies (ART): in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). While the ovarian steroid production was similar (estrone, 17β-estradiol) or higher (estriol) in ART pregnancies compared to mating, the levels of placental estriol were significantly lower in ART group. Placentas from ART had significantly higher activities of the steroid metabolizing enzymes UDP-glucuronosyltransferase (UGT) and sulfotransferase (SULT), which in ICSI were also coupled with decreased activity of the steroid regenerating enzymes β-glucuronidase (β-G) and Aryl sulfatase (AS). Levels of steroid metabolites androstane-3α-17β-diol glucuronide and dehydroepiandrosterone sulfate were higher in fetal compared to maternal blood in ART, but not in mating. This study demonstrates that in murine ART pregnancies, higher metabolism and clearance of steroids by the placenta may seriously affect the passage of essential hormones to the fetus. If a similar phenomenon exists in humans, this could provide a plausible explanation for obstetric and neonatal complications associated with ART, including the higher incidence of low birth weight babies.

    This paper highlights a number of theoretical issues relevant to this special issue of Culture, Health & Sexuality on the quality of offspring, including gender selection, ecofeminism, eugenics, reproductive agency, moral pioneering and reproductive pragmatism in China, India and Japan. First, it discusses various approaches to choice in sex selection, focusing on an instrumentalist and an ecofeminist approach. Second, it discusses issues of reproductive choice in the light of various concepts of eugenics and power, which have been used to characterise the relationship between the state, the individual and prenatal genetic testing. Third, it queries Foucault's notion of biopower in relation to reproductive agency. In reviewing the evidence, the chapter raises questions about how women and parents in Asian societies can be understood in terms of 'reproductive pragmatism', 'empowerment' and/or 'moral pioneering' when faced with the use of new reproductive technologies in modern societies.

    The purpose of this study was to assess reproductive health professionals' familiarity with and use of various electronic technologies to support health promotion. The study also examined the relationship between demographic characteristics and attitudes and beliefs of the effectiveness of new technologies and perceived barriers for usage. A total of 165 reproductive health professionals at two conferences related to reproductive health in the United States completed the study survey. Personal and organizational factors affected the adoption of electronic technologies for health promotion. This included lack of knowledge, skills, and confidence as well as privacy concerns. The results of the study also suggested that being from an older generation was associated with having lower levels of knowledge, skills, and confidence in using new media. These findings highlight the importance of creating learning opportunities on the use of new technology for health promotion as well as addressing specific perceived barriers among reproductive health professionals in order to promote the adoption of these technologies.

    2014-10-01

    The regulation of assisted reproductive technologies is a contested area. Some jurisdictions, such as the UK and a number of Australian states, have comprehensive regulation of most aspects of assisted reproductive technologies; others, such as the USA, have taken a more piecemeal approach and rely on professional guidelines and the general regulation of medical practice to govern this area. It will be argued that such a laissez-faire approach is inadequate for regulating the complex area of assisted reproductive technologies. Two key examples, reducing multiple births and registers of donors and offspring, will be considered to illustrate the effects of the regulatory structure of assisted reproductive technologies in the USA on practice. It will be concluded that the regulatory structure in the USA fails to provide an adequate mechanism for ensuring the ethical and safe conduct of ART services, and that more comprehensive regulation is required.

Some jurisdictions, such as the UK and a number of Australian states, have comprehensive regulation of most aspects of assisted reproductive technologies; others, such as the USA, have taken a more piecemeal approach and rely on professional guidelines and the general regulation of medical practice to govern this area. It will be argued that such a laissez-faire approach is inadequate for regulating the complex area of assisted reproductive technologies. Two key examples, reducing multiple births and registers of donors and offspring, will be considered to illustrate the effects of the regulatory structure of assisted reproductive technologies in the USA on practice. It will be concluded that the regulatory structure in the USA fails to provide an adequate mechanism for ensuring the ethical and safe conduct of ART services, and that more comprehensive regulation is required.

    New synergies across anthropology, science and technology studies (STS), legal studies and sociology, bring fresh theoretical perspectives to the study of reproduction. Recent works on reproduction trace some of the changing rationalities: from the tactics of feminist self-help health movements in 1970s and 1980s in the US, to the commercialized experience of pregnancy and the various configurations, policies and legalities addressing globalized genetic and assisted reproductive technologies. Reproductive decision-making is deeply entangled with neoliberalism, welfare reforms, racial and geographic disparities, economic stratification and cultural rationalities to produce inequalities. Studies of reproduction remain central to basic anthropological questions: what it means to be human, what constitutes life, how we live our lives, and how societies value particular lives.

    Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea in the year of 1985. However, it deserve to say that the invaluable data from fertility centers may serve as a useful source to find out which factors affect successful IVF outcome and to offer applicable information to infertile patients and fertility clinics. This article intended to report the status of ART in 2009 Korean Society of Obstetrics and Gynecology surveyed. The current survey was performed to assess the status and success rate of ART performed in Korea, between January 1 and December 31, 2009. Reporting forms had been sent out to IVF centers via e-mail, and collected by e-mail as well in 2012. With International Committee Monitoring Assisted Reproductive Technologies recommendation, intracytoplasmic sperm injection (ICSI) and non-ICSI cases have been categorized and also IVF-ET cases involving frozen embryo replacement have been surveyed separately. Seventy-four centers have reported the treatment cycles initiated in the year of 2009, and had performed a total of 27,947 cycles of ART treatments. Among a total of 27,947 treatment cycles, IVF and ICSI cases added up to 22,049 (78.9%), with 45.3% IVF without ICSI and 54.7% IVF with ICSI, respectively. Among the IVF and ICSI patients, patients confirmed to have achieved clinical pregnancy was 28.8% per cycle with oocyte retrieval, and 30.9% per cycle with embryo transfer. The most common number of embryos transferred in 2009 is three embryos (40.4%), followed by 2 embryos (28.4%) and a single embryo transferred (13.6%). Among IVF and ICSI cycles that resulted in multiple live births, twin pregnancy rate was 45.3% and triple pregnancy rate was 1.1%. A total of 191 cases of oocyte donation had been performed to result in 25.0% of live birth rate. Meanwhile, a total of 5,619 cases of frozen embryo replacement had been performed with 33.7% of clinical

    Objective Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea. This study was designed to report on the current status of ART therapy in South Korea between January 1 and December 31 of 2010. Methods A revised survey, originally developed by the International Committee Monitoring Assisted Reproductive Technologies, was sent to all available ART centers via email in 2013. Fresh embryo transfer (FET) cases were categorized into standard IVF or intracytoplasmic sperm injections. These cases, the thawing embryo transfer (TET) cases, and other related procedures were surveyed. Results Data from 30,785 ART procedures were provided by 78 clinics. Of the 28,200 cycles in which oocytes were retrieved, 92.2% of these cycles were completely transferred. In addition, 8,075 cycles were confirmed to be clinical pregnancies in the FET cycles, which represent a pregnancy rate of 28.6% per oocyte pick-up and 31.1% per embryo transfer. The most common number of embryos transferred in the FET was three embryos (37.3%) followed by two embryos (36.3%) and one embryo (14.0%). Of the 6,648 TET cycles transferred, 2,356 clinical pregnancies were confirmed by ultrasonography. The most common number of embryos in the TET group was two embryos (43.4%) followed by three embryos (25.4%) and one embryo (18.9%). Conclusion The clinical pregnancy rate per transfer in the FET cycles was similar in 2009 and 2010. Among the FET cycles where one or two embryos were transferred, the clinical pregnancy rate per transfer slightly increased from 2009 (28.7%) to 2010 (32.9%). PMID:25874168

The Center has established itself as an agent for technology transfer and economic development in- the Clear Lake community, and is positioned to continue as a stand-alone operation. This report presents data on the experimental JTCC program, including all objective measures tracked over its duration. While the metrics are all positive, the data indicates a shortage of NASA technologies with strong commercial potential, barriers to the identification and transfer of technologies which may have potential, and small financial return to NASA via royalty-bearing licenses. The Center has not yet reached the goal of self-sufficiency based on rental income, and remains dependent on NASA funding. The most important issues raised by the report are the need for broader and deeper community participation in the Center, technology sourcing beyond JSC, and the form of future funding which will be appropriate.

This approach contrasts with the ethical views of secular philosophers on human embryo research for therapeutic purposes. The challenges for Catholic healthcare institutions is to find ethical ways of using suitable pluripotent stem cells for therapies without creating or destroying human embryos. Catholic teaching on infertility treatment and reproductive technology are presented with emphasis given to the ethical need for children to be conceived and born of the marriage union compared with alterative ethical approaches for the use of infertility treatment and reproductive technology.

    2010-02-01

    Cross-border reproductive care, also called reproductive tourism, refers to the travelling of citizens from their country of residence to another country in order to receive fertility treatment through assisted reproductive technology. Several reasons account for cross-border reproductive care: (i) a certain kind of treatment is forbidden by law in the couple's own country or is inaccessible to the couple because of their demographic or social characteristics; (ii) foreign centres report higher success rates compared with those of the centres in the country of residence; (iii) a specific treatment may be locally unavailable because of a lack of expertise or because the treatment is considered experimental or insufficiently safe; and (iv) limited access to the treatment in the couple's home country because of long waiting lists, excessive distance from a centre or high costs. Although cross-border reproductive care can be viewed as a safety valve, the phenomenon is often associated with a high risk of health dangers, frustration and disparities. Solutions to these problematic effects need to be considered in the light of the fact that cross-border reproductive care is a growing phenomenon.

    This article critically evaluates the central claims of the various feminist responses to new reproductive arrangements and technologies. Proponents of a "progressivism" object to naive technological optimism and raise questions about the control of such technology. Others, such as the FINRRAGE group, raise concerns about the potentially damaging consequences of the new technologies for women. While a central concern is whether these technologies reinforce harmful biologically determinist stereotypes of women, it may be that these critiques function with a devastating gender blindness that puts women at risk in other, heretofore unnoticed, ways.

    The centering of an optical lens is the grinding of its edge profile or contour in relationship to its optical axis. This is required to ensure that the lens vertex and radial centers are accurately positioned within an optical system. Centering influences the imaging performance and contrast of an optical system. Historically, lens centering has been a purely manual process. Along its 62 years of assembling centering machines, Satisloh introduced several technological milestones to improve the accuracy and quality of this process. During this time more than 2.500 centering machines were assembled. The development went from bell clamping and diamond grinding to Laser alignment, exchange chuckor -spindle systems, to multi axis CNC machines with integrated metrology and automatic loading systems. With the new centering machine C300, several improvements for the clamping and grinding process were introduced. These improvements include a user friendly software to support the operator, a coolant manifold and "force grinding" technology to ensure excellent grinding quality and process stability. They also include an air bearing directly driven centering spindle to provide a large working range of lenses made of all optical materials and diameters from below 10 mm to 300 mm. The clamping force can be programmed between 7 N and 1200 N to safely center lenses made of delicate materials. The smaller C50 centering machine for lenses below 50 mm diameter is available with an optional CNC loading system for automated production.

    The Princeton Plasma Physics Laboratory (PPPL) demonstration of the diamond wire cutting technology on the surrogate of the Tokamak Fusion Test Reactor (TFTR), Figure 1, was performed from August 23-September 3, 1999. The plated diamond wire, Figure 2, was successful in cutting through all components of the TFTR surrogate including stainless steel, inconel and graphite. The demonstration tested three different void fill materials (mortar with sand, Rheocell-15, and foam) and three cooling systems (water, air, and liquid nitrogen). The optimum combination was determined to be the use of the low-density concrete void fill, Rheocell-15 with an average density of 52 lbs/ft{sup 3}, using a water coolant. However, the liquid nitrogen performed better than expected with only minor problems and was considered to be a successful demonstration of the Bluegrass Concrete Cutting, Inc. proprietary liquid-nitrogen coolant system. Data from the demonstration is being calculated and a summary of the technology demonstration will be included in the October monthly report. An ITSR will be written comparing the diamond wire saw to the plasma arc (baseline) technology. The MTR Chemical Protective Suit, a proprietary new suit from Kimberly Clark, was evaluated from 8/9/99 to 8/12/99 at Beaver, WV. This particular suit was tested on subjects performing three different tasks: climbing through a horizontal confined space, vertical confined space (pit), and loading and unloading material using a wheel barrow. Multiple test subjects performed each task for 20 minutes each. Performance of the innovative suit was compared to two commonly used types of protective clothing.

  2. Just another reproductive technology? The ethics of human reproductive cloning as an experimental medical procedure.

    2006-10-01

    Human reproductive cloning (HRC) has not yet resulted in any live births. There has been widespread condemnation of the practice in both the scientific world and the public sphere, and many countries explicitly outlaw the practice. Concerns about the procedure range from uncertainties about its physical safety to questions about the psychological well-being of clones. Yet, key aspects such as the philosophical implications of harm to future entities and a comparison with established reproductive technologies such as in vitro fertilisation (IVF) are often overlooked in discussions about HRC. Furthermore, there are people who are willing to use the technology. Several scientists have been outspoken in their intent to pursue HRC. The importance of concerns about the physical safety of children created by HRC and comparisons with concerns about the safety of IVF are discussed. A model to be used to determine when it is acceptable to use HRC and other new assisted reproductive technologies, balancing reproductive freedom and safety concerns, is proposed. Justifications underpinning potential applications of HRC are discussed, and it is determined that these are highly analogous to rationalisations used to justify IVF treatment. It is concluded that people wishing to conceive using HRC should have a prima facie negative right to do so.

    The Online Measurement of Decontamination project team received a commitment for a demonstration in May from the Sacramento (California) Municipal Utility District (SMUD) Rancho Seco site. Since this site is a member of the DOE Commercial Utilities Consortium, the demonstration will fulfill the DOE and commercial technology demonstration requirements. Discussion on deployment of the Integrated Vertical and Overhead Decontamination (IVOD) System at Rancho Seco was conducted; date for deployment tentatively scheduled for early spring. Based upon fictional requirements from SRS for a shiny monitor in a high-level waste tank, FIU-HCET developed and delivered a draft slurry monitor design and draft test plan. Experiments measuring slurry settling time for SRS slurry simulant at 10 wt% have been completed on FIU-HCET'S flow loop with SRS dip. The completed design package of the test mockup for evaluating Non-Intrusive Location of Buried Items Technologies was sent to Fluor Fernald and the Operating Engineers National Hazmat Program for review. Comments are due at the end of January. Preliminary experiments to determine size distribution of aerosols generated during metal cutting were performed. A 1/4-inch-thick iron plate was cut using a plasma arc torch, and the size distribution of airborne particles was measured using a multistage impactor. Per request of DOE-Ohio, FIU-HCET participated in a weeklong value engineering study for the characterization, decontamination, and dismantlement of their critical path facility.

    Reproduction in domestic animals is under control by man and the technologies developed to facilitate that control have a major impact on the efficiency of food production. Reproduction is an energy-intensive process. In beef cattle, for example, over 50 % of the total feed consumption required to produce a unit of meat protein is consumed by the dam of the meat animal (Anim Prod 27:367-379, 1978). Sows are responsible for about 20 % of the total feed needed to produce animals for slaughter (Adv Pork Prod 19:223-237, 2008). Accordingly, energy input to produce food from animal sources is reduced by increasing number of offspring per unit time a breeding female is in the herd. Using beef cattle as an example again, life-cycle efficiency for production of weaned calves is positively related to early age at puberty and short calving intervals (J Anim Sci 57:852-866, 1983). Reproductive technologies also dictate the strategies that can be used to select animals genetically for traits that improve production. Of critical importance has been artificial insemination (AI) (Anim Reprod Sci 62:143-172, 2000; Stud Hist Philos Biol Biomed Sci 38:411-441, 2007; Reprod Domest Anim 43:379-385, 2008; J Dairy Sci 92:5814-5833, 2009) and, as will be outlined in this chapter, emerging technologies offer additional opportunities for improvements in genetic selection. Given the central role of reproduction as a determinant of production efficiency and in genetic selection, improvements in reproductive technologies will be crucial to meeting the challenges created by the anticipated increases in world population (from seven billion people in 2011 to an anticipated nine billion by 2050; World population prospects: the 2010 revision, highlights and advance tables.

    2014-01-01

    The Food and Agriculture Organization of the United Nations (FAO) estimates that in 2012 aquaculture production of fish will meet or exceed that of the capture fisheries for the first time. Thus, we have just turned the corner from a predominantly hunting gathering approach to meeting our nutritional needs from fish, to a farming approach. In 2012, 327 finfish species and five hybrids were covered by FAO aquaculture statistics, although farming of carps, tilapias, salmonids, and catfishes account for most of food-fish production from aquaculture. Although for most major species at least part of production is based on what might be considered domesticated animals, only limited production in most species is based on farming of improved lines of fish or is fully independent of wild seedstock. Consistent with the infancy of most aquaculture industries, much of the development and implementation of reproductive technologies over the past 100 years has been directed at completion of the life cycle in captivity in order to increase seed production and begin the process of domestication. The selection of species to farm and the emphasis of selective breeding must also take into account other ways to modify performance of an animal. Reproductive technologies have also been developed and implemented to affect many performance traits among fishes. Examples include technologies to control gender, alter time of sexual maturation, and induce sterilization. These technologies help take advantage of sexually dimorphic growth, overcome problems with growth performance and flesh quality associated with sexual maturation, and genetic containment. Reproductive technologies developed to advance aquaculture and how these technologies have been implemented to advance various sectors of the aquaculture industry are discussed. Finally, we will present some thoughts regarding future directions for reproductive technologies and their applications in finfish aquaculture. PMID:24170354

  11. Reproductive technologies relevant to the genome resource bank in Carnivora.

    PubMed

    Amstislavsky, S; Lindeberg, H; Luvoni, Gc

    2012-02-01

    Carnivora is one of the most species-rich order of Mammalia. Some species, e.g. domestic cats, dogs and ferrets, are among the most popular pets; others, such as minks and farmed foxes, have economic value for the fur breeding industry. Still others, such as tigers, bears and other top predators, have great impact on the health of natural ecosystems. Most if not all Carnivora species have great cultural and aesthetic importance for man. There are enormous differences between mammalian species in reproductive physiology, and it is not surprising that reproductive technologies can be used with high efficiency with some animal groups, e.g. most farm animals and laboratory rodents, but are very laborious when used with Carnivora species, which often possess unique reproductive traits. The efficiency of assisted reproductive technology (ART) applied to semi-domestic, non-domestic and especially to endangered species of Carnivora remains extremely low in most cases, and often the first positive result reported is the only instance when ART has been successful with that species. Although there are approximately 270 species in the Carnivora order, to the best of our knowledge, successful published attempts to apply ART have been reported for only four families: Mustelidae, Felidae, Canidae and Ursidae. The main achievements in ART, embryo technology in particular, for these families of Carnivora, together with challenges and problems, are reviewed in the relevant sections.

  12. Applied reproductive technologies and genetic resource banking for amphibian conservation.

    PubMed

    Kouba, Andrew J; Vance, Carrie K

    2009-01-01

    As amphibian populations continue to decline, both government and non-government organisations are establishing captive assurance colonies to secure populations deemed at risk of extinction if left in the wild. For the most part, little is known about the nutritional ecology, reproductive biology or husbandry needs of the animals placed into captive breeding programs. Because of this lack of knowledge, conservation biologists are currently facing the difficult task of maintaining and reproducing these species. Academic and zoo scientists are beginning to examine different technologies for maintaining the genetic diversity of founder populations brought out of the wild before the animals become extinct from rapidly spreading epizootic diseases. One such technology is genetic resource banking and applied reproductive technologies for species that are difficult to reproduce reliably in captivity. Significant advances have been made in the last decade for amphibian assisted reproduction including the use of exogenous hormones for induction of spermiation and ovulation, in vitro fertilisation, short-term cold storage of gametes and long-term cryopreservation of spermatozoa. These scientific breakthroughs for a select few species will no doubt serve as models for future assisted breeding protocols and the increasing number of amphibians requiring conservation intervention. However, the development of specialised assisted breeding protocols that can be applied to many different families of amphibians will likely require species-specific modifications considering their wide range of reproductive modes. The purpose of this review is to summarise the current state of knowledge in the area of assisted reproduction technologies and gene banking for the conservation of amphibians.

    Many couples present fertility problems at their reproductive age, and although in the last years, the efficiency of assisted reproduction techniques has increased, these are still far from being 100% effective. A key issue in this field is the proper assessment of germ cells, embryos and endometrium quality, in order to determine the actual likelihood to succeed. Currently available analysis is mainly based on morphological features of oocytes, sperm and embryos and although these strategies have improved the results, there is an urgent need of new diagnostic and therapeutic tools. The emergence of the - OMICS technologies (epigenomics, genomics, transcriptomics, proteomics and metabolomics) permitted the improvement on the knowledge in this field, by providing with a huge amount of information regarding the biological processes involved in reproductive success, thereby getting a broader view of complex biological systems with a relatively low cost and effort.

  14. An ethical issue for reproductive technologies.

    Poplawski, N K

    The establishment of "new birth technologies" (such as ovulation induction, in vitro fertilization and gamete intrafallopian transfer) has raised many ethical issues. One such issue is "selective fetal reduction", a process advocated in the management of excessive multiple pregnancy. The ethics of "selective fetal reduction" involve consideration of not only the efficacy of the process and the destruction of fetuses per se, but more specifically consideration of the moral dilemma of destroying some fetuses for the probable benefit of the remainder. The latter I consider here. Following from this ethical analysis it is suggested that the law regarding abortion should permit selective reduction in high multiple pregnancies, that is pregnancies of 4 or above. I contend that the law should prohibit deliberate exposure (in an infertility programme) to significant risk of high multiple pregnancy, when there is full intention to reduce any subsequent pregnancy of high multiple size.

    The Graduate Automotive Technology Education (GATE) Center at the University of Tennessee, Knoxville has completed its sixth year of operation. During this period the Center has involved thirteen GATE Fellows and ten GATE Research Assistants in preparing them to contribute to advanced automotive technologies in the center's focus area: hybrid drive trains and control systems. Eighteen GATE students have graduated, and three have completed their course work requirements. Nine faculty members from three departments in the College of Engineering have been involved in the GATE Center. In addition to the impact that the Center has had on the students and faculty involved, the presence of the center has led to the acquisition of resources that probably would not have been obtained if the GATE Center had not existed. Significant industry interaction such as internships, equipment donations, and support for GATE students has been realized. The value of the total resources brought to the university (including related research contracts) exceeds $4,000,000. Problem areas are discussed in the hope that future activities may benefit from the operation of the current program.

    Objective The number of assisted reproductive technology (ART) clinics, ART cycles, clinical pregnancy rate (CPR), and number of newborns conceived using ART have steadily increased in South Korea. This aim of this study was to describe the status of ART in South Korea between January 1 and December 31, 2011. Methods A localized online survey was created and sent to all available ART centers via email in 2015. Fresh embryo transfer (FET) cases were categorized depending on whether standard in vitro fertilization, intracytoplasmic sperm injection (ICSI), or half-ICSI procedures were used. Thawed embryo transfer (TET) and other related procedures were surveyed. Results Data from 36,990 ART procedures were provided by 74 clinics. Of the 30,410 cycles in which oocytes were retrieved, a complete transfer was performed in 91.0% (n=27,683). In addition, 9,197 cycles were confirmed to be clinical pregnancies in the FET cycles, representing a pregnancy rate of 30.2% per oocyte pick-up and 33.2% per ET. The most common number of embryos transferred in the FET procedures was three (38.1%), followed by two (34.7%) and one (14.3%). Of the 8,826 TET cycles, 3,137 clinical pregnancies (31.1%) were confirmed by ultrasonography. Conclusion While the overall clinical pregnancy rate for the TET cycles performed was lower than the rate reported in 2010 (31.1% vs. 35.4%), the overall CPR for the FET cycles was higher than in 2010 (33.2% in 2011 and 32.9% in 2010). The most common number of embryos transferred in FET cycles was three, as was the case in 2010. PMID:27104156

  17. What would an environmentally sustainable reproductive technology industry look like?

    PubMed

    Richie, Cristina

    2015-05-01

    Through the use of assisted reproductive technologies (ARTs), multiple children are born adding to worldwide carbon emissions. Evaluating the ethics of offering reproductive services against its overall harm to the environment makes unregulated ARTs unjustified, yet the ART business can move towards sustainability as a part of the larger green bioethics movement. By integrating ecological ethos into the ART industry, climate change can be mitigated and the conversation about consumption can become a broader public discourse. Although the impact of naturally made children on the environment is undeniable, I will focus on the ART industry as an anthropogenic source of carbon emissions which lead to climate change. The ART industry is an often overlooked source of environmental degradation and decidedly different from natural reproduction as fertility centres provide a service for a fee and therefore can be subject to economic, policy and bioethical scrutiny. In this article, I will provide a brief background on the current state of human-driven climate change before suggesting two conservationist strategies that can be employed in the ART business. First, endorsing a carbon capping programme that limits the carbon emissions of ART businesses will be proposed. Second, I will recommend that policymakers eliminate funded ARTs for those who are not biologically infertile. I will conclude the article by urging policymakers and all those concerned with climate change to consider the effects of the reproductive technologies industry in light of climate change and move towards sustainability.

  1. Application of reproductive technology to the Australian livestock industries.

    PubMed

    Evans, G

    1991-01-01

    Current use of reproductive technology in the Australian livestock industries is limited, though it increased in line with higher prices for beef and wool through the 1980s. The required techniques, many of which were developed in Australia, are available and the level of expertise is comparable to the best in the world. However, the extensive pastoral industries do not readily lend themselves to these procedures. Only in the dairy industry is artificial insemination used to a significant degree. On the other hand, application of the technology in the pastoral industries is confined largely to studs and breeding cooperatives which provide breeding animals for producer flocks and herds. Hence the impact of applied technology may be more widespread than first appears. Until recently, little regard was paid to application of the technology along sound breeding principles. Artificial insemination and multiple ovulation and embryo transfer (MOET) have not been used so much in planned breeding programmes aimed at local improvement of stock, but more to proliferate genes of reputedly superior stock, imported either from overseas or elsewhere in Australia. This is particularly true of MOET, where the incentive to use it is commonly a short term cash gain made from proliferating breeding stock of a particularly valuable and usually novel strain or breed. Recent technological improvements which render the use of reproductive technology cheaper and more effective will lead to its more widespread use in commercial practice. Techniques for embryo freezing and splitting have been greatly simplified and quickly put into practice. The novel livestock technologies of in vitro oocyte maturation and fertilization have already found commercial application overseas. Fecundity-enhancing products have also been adopted by the livestock industries. There is potential value for greater use of reproductive technology in the livestock industries provided it is implemented according to sound

To implement this mission, JSC has focused on developing the infrastructure and partnerships that enable the technology development for future NASA programs. In our efforts to develop key technologies, we have found that collaborative relationships with private industry and academia strengthen our capabilities, infuse innovative ideas, and provide alternative applications for our development projects. The American public has entrusted NASA with the responsibility for space--technology development, and JSC is committed to the transfer of the technologies that we develop to the private sector for further development and application. It is our belief that commercialization of NASA technologies benefits both American industry and NASA through technology innovation and continued partnering. To this end, we present the 1998-1999 JSC Research and Technology Report. As your guide to the current JSC technologies, this report showcases the projects in work at JSC that may be of interest to U.S. industry, academia, and other government agencies (federal, state, and local). For each project, potential alternative uses and commercial applications are described.

    This review, is a synopsis of advanced reproductive technologies in farm animals, including the discussion of their limiting factors as revealed by the study of offspring derived from embryos produced in vitro and through cloning. These studies show that the problems of epigenetic mis-programming, which were reported in the initial stages of assisted reproduction, still persist. The importance of whole-genome analyses, including the methylome and transcriptome, in improving embryo biotechnologies in farm animals, are discussed. Genome editing approaches for the improvement of economically-relevant traits in farm animals are also described. Efficient farm animal embryo biotechnologies, including cloning and the most recent technologies such as genome editing, will effectively complement the latest strategies to accelerate genetic improvement of farm animals.

    Radical feminists have argued for both the radical potential of assisted reproductive technology (ART) and its oppressive and damaging effects for women. This paper will address the question of what constitutes a radical feminist position on ART; I will argue that the very debate over whether ART liberates or oppresses women is misguided, and that instead the issue should be understood dialectically. Reproductive technologies are neither inherently liberating nor entirely oppressive: we can only understand the potential and effects by considering how they are actually taken up within a culture. The internal contradictions, tensions, and inconsistencies within ART and the way it is addressed within the law points to a dialectic that resists a simple reductivist understanding. PMID:19076939

    Although semiconductor manufacturers have provided temporary relief with lower-power multi-core microprocessors, OEMs and data center operators continue to push the limits for individual rack power densities. It is not uncommon today for data center operators to deploy multiple 20 kW racks in a facility. Such rack densities are exacerbating the major issues of power and cooling in data centers. Data center operators are now forced to take a hard look at the efficiencies of their data centers. Malone and Belady (2006) have proposed three metrics, i.e., Power Usage Effectiveness (PUE), Data Center Efficiency (DCE), and the Energy-to-Acquisition Cost ratio (EAC), to help data center operators quickly quantify the efficiency of their data centers. In their paper, Malone and Belady present nominal values of PUE across a broad crosssection of data centers. PUE values are presented for data centers at four levels of optimization. One of these optimizations involves the use of Computational Fluid Dynamics (CFD). In the current paper, CFD is used to conduct an in-depth investigation of a liquid-cooled data center that would potentially be housed at the Pacific Northwest National Labs (PNNL). The boundary conditions used in the CFD model are based upon actual measurements on a rack of liquid-cooled servers housed at PNNL. The analysis shows that the liquid-cooled facility could achieve a PUE of 1.57 as compared to a PUE of 3.0 for a typical data center (the lower the PUE, the better, with values below 1.6 approaching ideal). The increase in data center efficiency is also translated into an increase in the amount of IT equipment that can be deployed. At a PUE of 1.57, the analysis shows that 91% more IT equipment can be deployed as compared to the typical data center. The paper will discuss the analysis of the PUE, and will also explore the impact of the raising data center efficiency via the use of multiple cooling technologies and CFD analysis.

    The accurate reproduction of the form and surface details of missing body structures is an essential part of any successful prosthetic rehabilitation. It helps mask the prosthesis and gives confidence to the patient. This clinical report details the integration of multiple in-house digital technologies of laser scanning, rapid prototyping, and digital color scanning and formulating to improve the shape, texture, orientation, and color of auricular prostheses for 3 patients with missing unilateral ears. A structured light laser scanner was used to digitize the patient's nondefect ear. The digitized data were then manipulated in specialist software and mirrored to reflect the opposing side. A rapid prototyping machine was used to manufacture a 3-dimensional (3D) model of the soft tissue required. This 3D mirrored ear model allowed the accurate reproduction of missing soft tissue. A color spectrometer was used to accurately reproduce the skin tones digitally and physically.

    The Integrated Technology Assessment Center (ITAC) has developed a flexible systems analysis framework to identify long-term technology needs, quantify payoffs for technology investments, and assess the progress of ASTP-sponsored technology programs in the hypersonics area. For this, ITAC has assembled an experienced team representing a broad sector of the aerospace community and developed a systematic assessment process complete with supporting tools. Concepts for transportation systems are selected based on relevance to the ASTP and integrated concept models (ICM) of these concepts are developed. Key technologies of interest are identified and projections are made of their characteristics with respect to their impacts on key aspects of the specific concepts of interest. Both the models and technology projections are then fed into the ITAC's probabilistic systems analysis framework in ModelCenter. This framework permits rapid sensitivity analysis, single point design assessment, and a full probabilistic assessment of each concept with respect to both embedded and enhancing technologies. Probabilistic outputs are weighed against metrics of interest to ASTP using a multivariate decision making process to provide inputs for technology prioritization within the ASTP. ITAC program is currently finishing the assessment of a two-stage-to-orbit (TSTO), rocket-based combined cycle (RBCC) concept and a TSTO turbine-based combined cycle (TBCC) concept developed by the team with inputs from NASA. A baseline all rocket TSTO concept is also being developed for comparison. Boeing has recently submitted a performance model for their Flexible Aerospace System Solution for Tomorrow (FASST) concept and the ISAT program will provide inputs for a single-stage-to-orbit (SSTO) TBCC based concept in the near-term. Both of these latter concepts will be analyzed within the ITAC framework over the summer. This paper provides a status update of the ITAC program.

    Background Public interest in Assisted Reproductive Technology (ART) has remained high since the birth of the world’s first in vitro fertilization baby, Louise Brown, in the United Kingdom. ART allows scientists to manipulate the fertilization process in order to bypass some pathological obstacles such as blocked fallopian tubes and non-functioning ovaries in the females, and blocked vas deferens and low sperm count in the males. The purpose was to provide a historical outline and identify the researches that most contributed to ART. Methods A review of published experimental and clinical studies of assisted reproduction carried out at the University of Bristol library website (MetaLib®). A cross-search of seven different medical databases (AMED-Allied and Complementary Medicine Database, BIOSIS Previews on Web of Knowledge, Cochrane Library, Embase, and the Medline on Web of Knowledge, OvidSP and PubMed) was completed by using the key words to explore the major milestones and progress in the development and implementation of ART. Results A speedy advancement in the development of different assisted reproductive techniques makes infertility problem more treatable than it ever had been. Conclusion Although no other field in the medicine has integrated new knowledge into the daily practice more quickly than ART yet, there is a need for social research to counterbalance the dominance of biomedical one, in particular the people’s actual experiences and expectations of ART.

    Assisted reproductive technology (ART) programs are complex organizations requiring the integration of multiple disciplines. ISO 9001:2008 is a quality management system that is readily adaptable to an ART program. The value that ISO brings to the entire organization includes control of documents, clear delineation of responsibilities of staff members, documentation of the numerous processes and procedures, improvement in tracking and reducing errors, and overall better control of systems. A quality ART program sets quality objectives and monitors their progress. ISO provides a sense of transparency within the organization and clearer understanding of how service is provided to patients. Most importantly, ISO provides the framework to allow for continual improvement.

    The rapid development of assisted reproductive technologies (ART) raises complex ethical and social problems. This article explores how to perform ethical governance in ART and evaluates the social consequences. In order to urge doctors and patients to abide by medical ethics and moral norms and to ensure the successful development of ART, we argue that ethics committees must be robust and that their guidelines must be followed. Specifically, it is necessary to improve awareness of the fundamentals of ART and related ethical principles among doctors and patients. This includes the need to intensify mechanisms to fully monitor the implementation and enforcement of medical ethical principles and doctrines, such as informed consent. PMID:19492723

    This publication highlights the capabilities and achievements of the Savannah River Technology Center in the field of sensor technology. Sensors are developed to provide solutions for environmental and chemical analysis. Most of their sensor systems are based upon fiber optics. Fiber optic probes function in three main modes: as a reflected light probe, from opaque samples; as a transreflectance probe, which sample light reflected back from samples which can pass light; and a flow cell, which monitors light transmitted through a path which passes the process stream being tested. The sensor group has developed fiber optic based temperature probes, has combined fiber optics with sol-gel technology to monitor process streams using chemical indicators, has done development work on slip stream on-line sampling of chemical process streams, has developed software to aid in the analysis of chemical solutions, and has applied this technology in a wide range of emerging areas.

    This Technical Progress Report describes progress made on the seventeen subprojects awarded in the first year of Cooperative Agreement DE-FC26-02NT41607: Crosscutting Technology Development at the Center for Advanced Separation Technologies. This work is summarized in the body of the main report: the individual sub-project Technical Progress Reports are attached as Appendices. Due to the time taken up by the solicitation/selection process, these cover the initial 6-month period of project activity only. The U.S. is the largest producer of mining products in the world. In 1999, U.S. mining operations produced $66.7 billion worth of raw materials that contributed a total of $533 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Originally set up by Virginia Tech and West Virginia University, this endeavor has been expanded into a seven-university consortium--Virginia Tech, West Virginia University, University of Kentucky, University of Utah, Montana Tech, New Mexico Tech and University of Nevada, Reno--that is supported through U.S. DOE Cooperative Agreement No. DE-FC26-02NT41607: Crosscutting Technology Development at the Center for Advanced Separation Technologies. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (1) Solid-solid separation (2) Solid-liquid separation (3) Chemical/Biological Extraction (4) Modeling and Control, and (5) Environmental Control.

    2015-12-01

    This paper explores the limitations of epistemic scientism for understanding the role the concept of race plays in assisted reproductive technology (ART) practices. Two major limitations centre around the desire to use scientific knowledge to bring about social improvement. In the first case, undue focus is placed on debunking the scientific reality of racial categories and characteristics. The alternative to this approach is to focus instead on the way the race idea functions in ART practices. Doing so reveals how the race idea (1) helps to define the reproductive "problems" different groups of women are experiencing and to dictate when and how they should be "helped"; (2) helps to resolve tensions about who should be considered the real parents of children produced by reproductive technologies; and (3) is used to limit ART use where that use threatens to denaturalize the very sociopolitical landscape the race idea has created. In the second case, scientific knowledge regarding reproduction is thought to call for technological control over that reproduction. This leads to an overemphasis on personal responsibility and a depoliticization of racialized social inequalities.

    The Morgantown Energy Technology Center (METC), is an US Department of Energy (DOE) facility in Morgantown, West Virginia. It is responsible for conducting research and managing research contracts dealing with coal and gas technology. The purpose of the audit was to evaluate the effectiveness of METC's internal control systems for major contracts and small purchases. Improved internal controls are needed over major contracts and small purchases. Specifically, METC's contracting officer's representatives were not formally approving invoices prior to payment to document that the contracted services or materials were received. Additionally, METC's systems of internal controls for small purchases was not effective in the areas of funding authorization, acquisition planning, and invoice processing. These internal control weaknesses precluded METC from assuring that (1) its small purchase needs were fully funded and satisfied requirements most effectively and economically, and (2) its major contracts and small purchases were received and correctly paid. The audit recommends improved internal controls over these functions.

    1995-12-01

    The development of integrated gasification combined cycle (IGCC) and pressurized fluidized-bed combustion (PFBC) power systems has made it possible to use coal while still protecting the environment. Such power systems significantly reduce the pollutants associated with coal-fired plants built before the 1970s. This superior environmental performance and related high system efficiency is possible, in part, because particulate gas-stream cleanup is conducted at high-temperature and high-pressure process conditions. A main objective of the Particulate Cleanup Program at the Morgantown Energy Technology Center (METC) is to ensure the success of the CCT demonstration projects. METC`s Particulate Cleanup Program supports research, development, and demonstration in three areas: (1) filter-system development, (2) barrier-filter component development, and (3) ash and char characterization. The support is through contracted research, cooperative agreements, Cooperative Research And Development Agreements (CRADAs), and METC`s own in-house research. This paper describes METC`s Particulate Cleanup Program.

    Birth is not merely a biological event; it is also a social event in that it creates relationships. As a consequence of reproductive technologies, the boundaries between the biological and social basis of kinship have become blurred. Reproductive technologies challenge previously held cultural constructions of kinship and bring about new kinds of social relations in that kinship boundaries are redefined. This paper discusses the societal effects that reproductive technologies have had in challenging previously held notions of parenthood, kinship and relatedness. PMID:16234204

    Introduction This study illustrated the global contribution to assisted reproductive technologies (ARTs) research in MEDLINE database from 1998 to 2014. Methods In March 2015, the MEDLINE database was searched for research publications indexed under ‘reproductive techniques, assisted’ (including the following MeSH headings: in vitro fertilization [IVF]; intracytoplasmic sperm injections; cryopreservation; and ovulation induction), with the following expressions in the fields of title or abstract: intrauterine insemination; sperm donation; embryo/egg donation and surrogate mothers. The number of publications in MEDLINE database was recorded for each individual year, 1998–2014, and for each country. The following countries were arbitrarily selected for data retrieval: United States, United Kingdom, France, Germany, Canada, Italy, Japan (G7 countries), Brazil, Russia, India, China (BRIC countries), Egypt, Turkey, Israel and Iran. Results The absolute number of publications for each country from 1998 to 2014 ranged from 75 to 16453, with a median of 2024. The top five countries were the US (16453 publications), the UK (5427 publications), Japan (4805), China (4660) and France (3795). ART (20277), cryopreservation (11623) and IVF (11209) were the most researched areas. Conclusion Global research on ARTs were geographically distributed and highly concentrated among the world’s richest countries. Cryopreservation and IVF were the most productive research domains among ARTs. PMID:26813255

    Sperm selection plays an important role in assisted reproductive technology. In recent years, sperm evaluation is not limited to the assessment of sperm motility and morphology, but involves more other sperm characteristics such as sperm ultrastructure, DNA integrity, apoptosis and membrane. Assessment based on these characteristics is becoming the aim of sperm selection. This article gives an overview on several newly developed techniques for sperm selection according to different technical principles, such as electrophoretic separation, zeta potential, HA binding, Annexin V binding, intracytoplasmic morphologically selected sperm injection (IMSI) and microfluidic sperm sorter, which have all been applied to IVF or ICSI with the exception of microfluidic sperm sorter. It also introduces the advantages, disadvantages and application effects of these techniques.

    After the rapid increase in reports, bills, and regulations on assisted reproductive technologies (ART) in the 1980s, the first 3 years of the 1990s reveal a continuation of this trend notably in three major aspects. First, a certain consistency has developed in terms of the conditions of accessibility to ART, the definition of infertility, the terms of donation, and the primacy of social filiation, so that anonymity remains controversial. Second, the importance of protection of genetic material has been reaffirmed with regard to gamete and embryo conservation, embryo research, and, in particular, the acceptability of preimplantation diagnosis. Finally, the framework of practices concerning accreditation and control, organization of national data, and management of nominative information has been increasingly refined. PMID:8241439

    Background Women have been able to delay childbearing since effective contraception became available in the 1960s. However, fertility decreases with increasing maternal age. A slow but steady decrease in fertility is observed in women aged between 30 and 35 years, which is followed by an accelerated decline among women aged over 35 years. A combination of delayed childbearing and reduced fecundity with increasing age has resulted in an increased number and proportion of women of greater than or equal to 35 years of age seeking assisted reproductive technology (ART) treatment. Methods Literature searches supplemented with the authors' knowledge. Results Despite major advances in medical technology, there is currently no ART treatment strategy that can fully compensate for the natural decline in fertility with increasing female age. Although chronological age is the most important predictor of ovarian response to follicle-stimulating hormone, the rate of reproductive ageing and ovarian sensitivity to gonadotrophins varies considerably among individuals. Both environmental and genetic factors contribute to depletion of the ovarian oocyte pool and reduction in oocyte quality. Thus, biological and chronological ovarian age are not always equivalent. Furthermore, biological age is more important than chronological age in predicting the outcome of ART. As older patients present increasingly for ART treatment, it will become more important to critically assess prognosis, counsel appropriately and optimize treatment strategies. Several genetic markers and biomarkers (such as anti-Müllerian hormone and the antral follicle count) are emerging that can identify women with accelerated biological ovarian ageing. Potential strategies for improving ovarian response include the use of luteinizing hormone (LH) and growth hormone (GH). When endogenous LH levels are heavily suppressed by gonadotrophin-releasing hormone analogues, LH supplementation may help to optimize treatment

    Managing scientific data has been identified by the scientific community as one of the most important emerging needs because of the sheer volume and increasing complexity of data being collected. Effectively generating, managing, and analyzing this information requires a comprehensive, end-to-end approach to data management that encompasses all of the stages from the initial data acquisition to the final analysis of the data. Fortunately, the data management problems encountered by most scientific domains are common enough to be addressed through shared technology solutions. Based on community input, we have identified three significant requirements. First, more efficient access to storage systems is needed. In particular, parallel file system and I/O system improvements are needed to write and read large volumes of data without slowing a simulation, analysis, or visualization engine. These processes are complicated by the fact that scientific data are structured differently for specific application domains, and are stored in specialized file formats. Second, scientists require technologies to facilitate better understanding of their data, in particular the ability to effectively perform complex data analysis and searches over extremely large data sets. Specialized feature discovery and statistical analysis techniques are needed before the data can be understood or visualized. Furthermore, interactive analysis requires techniques for efficiently selecting subsets of the data. Finally, generating the data, collecting and storing the results, keeping track of data provenance, data post-processing, and analysis of results is a tedious, fragmented process. Tools for automation of this process in a robust, tractable, and recoverable fashion are required to enhance scientific exploration. The SDM center was established under the SciDAC program to address these issues. The SciDAC-1 Scientific Data Management (SDM) Center succeeded in bringing an initial set of advanced

    In Canada, the Assisted Human Reproduction Act received royal assent on 29 March 2004. The approach proposed by the federal government responds to Canadians' strong desire for an enforceable legislative framework in the field of reproduction technologies through criminal law. As a result of the widening gap between the rapid pace of technological change and governing legislation, a distinct need was perceived to create a regulatory framework to guide decisions regarding reproductive technologies. In this article the three main topics covered in the new legislation are commented on: cloning, germline therapy, and purchase of gametes and embryos. Some important issues also covered in the new legislation, such as privacy and access to information, data protection, identity of donors, and inspection, will not be addressed.

    Assisted reproductive technology (ART) has grown by leaps and bounds in the last few years. India has one of the highest growths in the ART centers and the number of ART cycles performed every year. Very soon India will be the leader in the world of ART in terms of a number of cycles. With the advances of technology and availability of techniques even in tier II and tier III cities our country, the results still vary dramatically. There is no standardization of protocols and reporting is very inadequate. Furthermore, there are only ART guidelines and no law still exists. Our first and the biggest challenge is to document the tremendous work being done in India and on the basis of analysis of this work, a proper registry can be made and guidance given to all on standardization and improvement. This is the 8th edition of National ART Registry of India being presented and analyzed. PMID:24672161

    Therapeutic advances in oncology have improved the prognosis for long-term survival of children and young adults. As well as other couples or because of adverse side effects of cancer treatments on reproductive function, some cancer survivors will therefore be brought to use assisted reproductive technologies (intrauterine inseminations, in vitro fertilization, intracytoplasmic sperm injection, oocyte or sperm donation…). The purpose of this review is to summarize available scientific datas regarding success rate of assisted reproductive technologies in cancer survivors.

    The U.S. is the largest producer of mining products in the world. In 2003, U.S. mining operations produced $57 billion worth of raw materials that contributed a total of $564 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (1) Solid-solid separation; (2) Solid-liquid separation; (3) Chemical/Biological Extraction; (4) Modeling and Control; and (5) Environmental Control.

To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Originally set up by Virginia Tech and West Virginia University, this endeavor has been expanded into a seven-university consortium -- Virginia Tech, West Virginia University, University of Kentucky, University of Utah, Montana Tech, New Mexico Tech and University of Nevada, Reno - that is supported through U.S. DOE Cooperative Agreement No. DE-FC26-02NT41607: Crosscutting Technology Development at the Center for Advanced Separation Technologies. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (1) Solid-solid separation; (2) Solid-liquid separation; (3) Chemical/biological extraction; (4) Modeling and control; and (5) Environmental control. Distribution of funds is handled via competitive solicitation of research proposals through Site Coordinators at the seven member universities. These were first reviewed and ranked by a group of technical reviewers (selected primarily from industry). Based on these reviews, and an assessment of overall program requirements, the CAST Technical Committee made an initial selection/ranking of proposals and forwarded these to the DOE/NETL Project Officer for final review and approval. The successful projects are listed by category, along with brief abstracts of their aims and objectives.

    Assisted reproductive technologies (ART) have changed life for the past 25 years and many ethical and social issues have emerged following this new method of conception. In order to protect individuals against scientific and ethical abuses without inhibiting scientific progress, a specific legal framework is necessary. The first French law on Bioethics was voted after an extensive debate in 1994 then reviewed in 2004. This review previously scheduled every five years is currently being discussed. Legal provisions applying to ART are part of a large framework including the protection of the patients' rights and biomedical research. The key principles consist of respect for human life and ban on commercial practices of human body parts, eugenic practices and any kind of cloning. These key principles apply to ART. Donation is anonymous and free. Created in 2004, the Agence de la biomédecine is a government agency and one of the main tools of the French regulations. The missions focus on improving the quality and the safety of the management of ART. Evaluation of activities is available to all from the annual report. The agency represents the French competent authority for medical and scientific aspects of ART. Substantial differences in European legislations exist from the open-up "laissez faire" to the most restrictive one. As a consequence a large reproductive tourism has developed particularly for egg donation or surrogacy. The medical and ethical conditions of management of patients and donors represent the main critical points. In order to avoid ethical abuses, homogenization regarding the key principles is necessary in Europe. It is an opportunity to reassert that human body parts should not be a source of financial gain.

    Diseases in end stage typically occur with hypothalamic-pituitary-ovarian axis disorders, with consequent anovulation and infertility. The solid organ transplantation increased survival of patients with end-stage organs disease and the vast majority of women improve their reproductive capacity after transplantation. Although adoption can always be a possibility, the transplanted infertile woman has the right to self-reproductive determination using assisted reproductive techniques. While it is known that pregnancies in transplantedwomen are at high risk, there is no evidence of differences in pregnancy outcome in pregnant transplanted subject to technical, compared with spontaneous pregnancies. The use of assisted reproductive techniques in transplanted women is a medical, ethical and psychosocial challenge, whose approach must be multidisciplinary, to ensure reproductive success without compromising the function of the transplanted organ or maternal health, allowing the birth of a healthy child. The literature remains scarce. Three clinical cases are presented.

    Birds have been useful in environmental monitoring within forest ecosystems and at a variety of industrial sites. Growth analyses have been shown to be a sensitive measure of environmental stress in gulls, eagles, and in passerine birds. As part of an intensive year-long baseline ecological study investigations were initiated in late spring 1987 in order to characterize growth and reproductive success in Mourning Doves (Zenaida macroura) and American Robins (Turdus migratorius) at the Feed Materials Production Center (FMPC). The current study was initiated in order to determine whether the pattern of suppressed growth and reproduction in FMPC birds still existed onsite. We selected only American robins (Turdus migratorius) for study because they appeared the most severely affected in 1987. 44 refs., 3 figs., 3 tabs.

    With the passage of The American Reinvestment and Recovery Act of 2009 that includes the Health Care Information Technology for Economic & Clinical Health Act, the opportunity for states to develop a Health Information Technology Center (THITC) has emerged. The Center provides the intellectual, financial, and technical leadership along with the governance and oversight for all health information technology-related activities in the state. This Center would be a free-standing, not-for-profit, public-private partnership that would be responsible for operating one or more (in large states) Regional Health Information Technology Extension Centers (Extension Centers) along with several Regional Health Information Exchanges (HIEs) and one or more Regional Health Information Data Centers (Data Centers). We believe that if these features and functions could be developed, deployed, and integrated statewide, the health and welfare of the citizens of the state could be improved while simultaneously reducing the costs associated with the provision of care.

    According to the WHO, infertility and sterility will be the third-most serious disease worldwide in the 21st century, after cancer and cardiovascular diseases. In contrast to developed countries, assisted reproductive technology (ART) were not offered in China until the mid-1980s with the first in vitro fertilization (IVF) infant born in Taiwan in 1985, then Hong Kong in 1986, and mainland China in 1988, respectively. Since those inceptions, the practice of ART in China has evoked a variety of social, cultural, political and one-child policy responses that have resulted in restrictions on the number of IVF cycles performed annually. According to recent survey, an estimate 40-50 million women and 45 million men suffered from infertility, which is estimated that more than ten million Chinese infertile couples require ART treatment. However, it has limited access to ART facilities, many of them may not have a child are whirling to all types of fertility therapies. Exposure to radiation, pesticides and other environmental pollutants, work-related stress and unhealthy lifestyles are believed to contribute to the increasing incidence of infertility in China. The aim of this first report is to provide China nationwide ART data and government policy in compliance and 
non-compliance, particularly related to family plan policy in China. PMID:26835327

    2013-01-01

    The cardiometabolic health of children conceived by assisted reproductive technologies (ART) compared with children conceived without medical assistance is unclear. Although the majority of published studies evaluating height, weight, and body mass index have not found differences by method of conception, some studies have indicated differences in adiposity by more direct measures such as skinfolds and dual X-ray absorptiometry. Far fewer studies have investigated other cardiometabolic characteristics, such as blood pressure and measures of lipid and glucose metabolism. Of these studies, some indications of increased blood pressure and recent findings of vascular dysfunction among children conceived by ART compared with children conceived without ART warrant further investigation. Epigenetic differences may be the global mechanism at work, resulting from different aspects of ART treatment, such as ovarian stimulation, in vitro culture, and manipulation of sperm, among other considerations. Fetal growth and placental development may serve as mediators of these effects. Future studies should consider recruiting sufficient numbers of ART and non-ART conceived multiples and collect information on indicators of cardiometabolic health in the parents. Despite some advantages of sibling cohorts in developmental origins research, its feasibility and utility for investigating health of children conceived by ART remains debatable. PMID:23312226

    Each amphibian species is evolutionarily distinct, having developed highly specialized and diverse reproductive strategies in both terrestrial and aquatic environments. These unique reproductive patterns and mechanisms, key to species propagation, have only been explored in a limited number of laboratory models. Although the development of applied reproductive technologies for amphibians has proven useful for a few threatened species, the real benefit of this technology has been new insights into the reproductive adaptations, behavior, endocrinology, and physiological mechanisms that have evolved over millions of years. As the basic fundamental database on amphibian reproductive physiology has grown, so has the applied benefit for species conservation. In particular, technologies such as non-invasive fecal and urinary hormone assays, hormone treatments for induced breeding or gamete collection, in vitro fertilization, and the ability to establish genome resource banks have all played important roles in monitoring or managing small populations of captive species. Amphibians have the ability to produce a large excess of germplasm (up to 10,000 ovulated eggs in a single reproductive event) that if not collected and preserved, would represent a wasted valuable resource. We discuss the current state of knowledge in assisted reproductive technologies for amphibians and why their extinction crisis means these available tools can no longer be implemented as small-scale, last-ditch efforts. The reproductive technologies must be established early as a key component of large-scale species recovery.

    Establishing a holistic approach for the enrollment of subjects into clinical trials that includes strategies for the recruitment of non-traditional and minority populations has been an elusive task. The existence of such a design, that is understood and embraced by investigators and the target communities, would streamline the current level of commitment of time, energy and resources. This is necessary to successfully encourage individual and community participation in research studies. The Center for Research in Reproduction at Meharry set out to recruit a large number of African American women volunteers of reproductive age into clinical trials. The experience, of recruiting volunteers from the African American community for clinical trials in the Meharry Medical College/Pennsylvania State University (MMC/PSU)'s Cooperative Center for Research in Reproduction at Meharry, is presented.

    OBJECTIVE To assess trends of tubal factor infertility and to evaluate risk of miscarriage and delivery of preterm or low birth weight (LBW) neonates among women with tubal factor infertility using assisted reproductive technology (ART). METHODS We assessed trends of tubal factor infertility among all fresh and frozen, donor, and nondonor ART cycles performed annually in the United States between 2000 and 2010 (N=1,418,774) using the National ART Surveillance System. The data set was then limited to fresh, nondonor in vitro fertilization cycles resulting in pregnancy to compare perinatal outcomes for cycles associated with tubal compared with male factor infertility. We performed bivariate and multivariable analyses controlling for maternal characteristics and calculated adjusted risk ratios (RRs) and 95% confidence intervals (CI). RESULTS The percentage of ART cycles associated with tubal factor infertility diagnoses decreased from 2000 to 2010 (26.02–14.81%). Compared with male factor infertility, tubal factor portended an increased risk of miscarriage (14.0% compared with 12.7%, adjusted RR 1.08, 95% CI 1.04–1.12); risk was increased for both early and late miscarriage. Singleton neonates born to women with tubal factor infertility had an increased risk of pre-term birth (15.8% compared with 11.6%, adjusted RR 1.27, 95% CI 1.20–1.34) and LBW (10.9% compared with 8.5%, adjusted RR 1.28, 95% CI 1.20–1.36). Significant increases in risk persisted for early and late preterm delivery and very low and moderately LBW delivery. A significantly elevated risk was also detected for twin, but not triplet, pregnancies. CONCLUSION Tubal factor infertility, which is decreasing in prevalence in the United States, is associated with an increased risk of miscarriage, preterm birth, and LBW delivery as compared with couples with male factor infertility using ART.

    Routine analysis of urinary metabolites of estrogen and progesterone provided substantial information about the estrous cycle of bears. However, these data alone were not adequate to determine the precise timing of ovulation needed to maximize AI success rates, or to distinguish between pregnancy and pseudopregnancy. Therefore, there is a critical need to develop technologies that will enhance understanding of the reproductive mechanisms of ursids. Using the domestic dog as a model, three techniques were investigated for potential application to the propagation of captive endangered bears. In a modification of standard staining of bitch vaginal cells, trichrome staining of giant panda cells revealed two consistent chromic shifts 9 and 2 days prior to the periovulatory decrease in urinary estrone sulfate, enhancing the ability to predict ovarian events preceding ovulation. To further define the relationship between the decrease in estrogen and ovulation, the utility of a rapid immunochromatographic LH assay was investigated for giant pandas using a commercial LH kit canine serum. Serum collected during estrus exhibited positive test results, indicating the cross-reactivity of giant panda LH with canine LH antibodies, and preliminary data supported further development of the LH kit for the detection of LH in bear urine. Due to the limitations of hormone analysis for distinguishing pregnancy from pseudopregnancy in canids and ursids, forward-looking infrared thermography was evaluated as a method to visualize proliferating placental tissue, fetuses, or both. While further investigation is needed to confirm the utility of thermal imaging for pregnancy diagnosis in the domestic bitch, pregnancy and pseudopregnancy were successfully detected in two giant pandas.

    Objective Nowadays, many infertile couples can have child by assistant reproductive technology (ART). Always the undesirable effects of these methods on newborn are considered and are evaluated. The aim of this study is to describe the impact of ART on ocular and visual performances of infants born by these methods. Materials and methods In a cross-sectional descriptive study, 479 infants aged three-nine months presented to an optometry clinic of Child Health and Development Research Department (CHDRD), Tehran, Iran. Static retinoscopy, qualitative fixation evaluation, Hirschberg test, red reflex assessment and external eye examination were carried out. Other information such as birth weight and maturity of the infants was recorded. Results It was possible to assess only 320 out of 479 infants due to general condition of some participants. Comparison of mean refractive error in infants’ right and left eyes did not show any significant difference. Our findings confirmed that 20.3% had poor fixation, while 2.9% revealed manifest strabismus. The results also revealed the prevalences of myopia, hyperopia and emmetropia are 2.9%, 87%, and 10.1%, respectively. Red reflex abnormalities were significantly found in boys and in preterm infants (p < 0.05). Failure of fixation control was seen more frequently with increasing refractive error, which significantly developed in preterm infants (p < 0.001). Conclusion These results reflect the necessity of more comprehensive assessments and further follow-up of infants born by ART, especially for premature male ART infants. These results also suggest the probability of fixation condition and visual deficiencies in these infants. It is recommended to pay close attention to this preliminary report about the refractive and fixation condition of the infants born after ART. PMID:24971123

    Infertility is a problem of global proportions, affecting on average 8-12 percent of couples worldwide. In some societies, however-particularly those in the "infertility belt" of sub-Saharan Africa-as many as one-third of all couples are unable to conceive. Factors causing high rates of tubal infertility in parts of the developing world include sexually transmitted, postpartum, and postabortion infections; however, male infertility, which is rarely acknowledged, contributes to more than half of all cases. Unfortunately, the new reproductive technologies (NRTs) such as in vitro fertilization (IVF), which are prohibitively expensive and difficult to implement in many parts of the developing world, represent the only solution to most cases of tubal and male infertility. Not surprisingly, these technologies are rapidly globalizing to pronatalist developing societies, where children are highly desired, parenthood is culturally mandatory, and childlessness socially unacceptable. Using Egypt as an illustrative case study, this paper examines five of the major forces fueling the global demand for NRTs; these include demographic and epidemiological factors, the fertility-infertility dialectic, problems in health care seeking, gendered suffering, and adoption restrictions. Following this overview, a detailed examination of the implications of the rapid global spread of NRTs to the developing world will be offered. By focusing on Egypt, where nearly 40 IVF centers are in operation, this article will demonstrate the considerable constraints on the practice and utilization of NRTs in a developing country on the "receiving end" of global reproductive technology transfer. The article concludes by stressing the need for primary prevention of infections leading to infertility, thereby reducing global reliance on NRTs.

  13. Natural gas technologies at Kennedy Space Center

    In 1994 Kennedy Space Center`s local gas distribution company (LDC), City Gas Company of Florida, undertook the construction of over 25 miles of high pressure natural gas piping to provide natural gas service to Kennedy Space Center (KSC). The Space Center, originally constructed in the 1960`s had used various grades of fuel oil throughout its history. But in the 1990`s concern about sulfur oxide emissions from hot water boilers, fuel spills, fuel prices, energy security, and federal mandates to use alternative fuels prompted KSC to investigate using natural gas as its primary fuel. Since completion of the pipeline in mid 1994, almost 4.5 million therms of natural gas have been used, displacing 2.9 million gallons of No. 2 fuel oil, and avoiding over 140 tons of air pollution. Another indicator of KSC`s effective switch to natural gas is that in 1993, KSC was by far the largest single consumer of petroleum fuel in NASA consuming 341 billion BTU`s, over 37% of all the petroleum fuel used by all NASA sites combined. In 1995, KSC petroleum fuel use had dropped to only 29 billion BTU`s while natural gas consumption was 308 billion BTU`s. These successes have encouraged KSC to explore other options for the use of natural gas at the Space Center. Under study at the present is natural gas cooling, fuel cells, and off road equipment fueling.

    The U.S. is the largest producer of mining products in the world. In 1999, U.S. mining operations produced $66.7 billion worth of raw materials that contributed a total of $533 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (a) Solid-solid separation (b) Solid-liquid separation (c) Chemical/Biological Extraction (d) Modeling and Control, and (e) Environmental Control. Distribution of funds is being handled via competitive solicitation of research proposals through Site Coordinators at the seven member universities. The first of these solicitations, referred to as the CAST II-Round 1 RFP, was issued on October 28, 2002. Thirty-eight proposals were received by the December 10, 2002 deadline for this RFP-eleven (11) Solid-Solid Separation, seven (7) Solid-Liquid Separation, ten (10) Chemical/Biological Extraction, six (6) Modeling & Control and four (4) Environmental Control. These were first reviewed and ranked by a group of technical reviewers (selected primarily from industry). Based on these reviews, and an assessment of overall program requirements, the CAST Technical Committee made an initial selection/ranking of proposals and forwarded these to the DOE/NETL Project Officer for final review and approval. This process took some 7 months to complete but 17 projects (one joint) were in place at the constituent universities (three at Virginia Tech, two at West Virginia University, three at University of Kentucky

    The meiotic spindle in the oocyte is composed of microtubules and plays an important role during chromosome alignment and separation at meiosis. Polarized light microscopy (PLM) could be useful for a non-invasive evaluation of the meiotic spindle and may allow removal of nuclear structures without fluorochrome staining and ultraviolet exposure. In this study, PLM was used to assess its potential application in porcine reproductive technologies. The objectives of the present study were to assess the efficiency of PLM to detect microtubule-polymerized protein in in vitro-matured porcine oocytes; to examine its effects on the oocyte developmental competence; to select oocytes based on the presence of the meiotic spindle detected by PLM; and to assess the efficiency oocyte enucleation assisted with PLM. In the first experiment, the presence of microtubule-polymerized protein was assessed and confirmed in oocytes (n = 117) by immunostaining and chromatin detection. In the second experiment, oocytes (n = 160) were exposed or not (controls) to PLM for 10 minutes, and then parthenogenetically activated and cultured in vitro. In the third experiment, development competence of oocytes with a positive or negative signal to PLM was analyzed after in vitro fertilization. Finally, oocytes (n = 54) were enucleated using PLM as a tool to remove the meiotic spindle. A positive PLM signal was detected in 98.2 % of the oocytes, which strongly correlated (r = 1; p < 0.0001) with the presence of microtubule-polymerized protein as confirmed by immunostaining. Oocytes exposed to PLM did not differ significantly from controls on cleavage, total blastocyst, expanded blastocyst rates and total cell numbers. The percentage of oocytes at the MII stage and blastocyst formation rate in the negative PLM group significantly differed from control and PLM positive groups. Overall efficiency of spindle removal using the PLM-Oosight system was 92.6%. These results suggest that polarized light

  2. Cryopreservation and delayed embryo transfer-assisted reproductive technology registry and reporting implications.

    PubMed

    Doody, Kevin J

    2014-07-01

    Clinics performing assisted reproductive technology (ART) procedures have collected data via registry and publicly reported pregnancy outcomes for more than 25 years. During this time, the practice of ART has changed considerably with frozen embryo transfer (FET) procedures contributing an increasing proportion of live births. Cycles initiated with the intent of embryo banking for the purpose of fertility preservation have been excluded from these public reports, because pregnancy outcomes are not immediately available. An unintended consequence of the common sense handling of fertility preservation has been that cycles performed with intentional short-term cryopreservation of all embryos for other indications have also been excluded from the report. Over the last few years, cryopreservation with short-term delayed transfer increasingly has been performed for reasons other than fertility preservation. The pregnancy outcomes of these cycles are expected within a reasonable time frame and should be transparently reported. The Society for Assisted Reproductive Technology has collaborated with the Centers for Disease Control and Prevention to "recapture" these cycles for the public reports. This recapture is done by linking the FET cycles to the stimulation cycles from which the embryos were derived and by changing the labels of the outcome success metrics. Stimulations using ART, initiated for the purpose of transferring embryos within 1 year will be included in the report despite any prospective intent to freeze all eggs or embryos. A positive outcome will be reported when a live birth results from the first embryo transfer following stimulation ("primary transfer"). Linkage of ovarian stimulation and egg-retrieval procedures to FET will also allow development of other success metrics to further benefit fertility patients.

    Background Assisted Reproductive Technology (ART) reports generated by the Centers for Disease Control and Prevention (CDC) exclude embryo banking cycles from outcome calculations. Methods We examined data reported to the CDC in 2013 for the impact of embryo banking exclusion on national ART outcomes by recalculating autologous oocyte ART live birth rates. Inflation of reported fresh ART cycle live birth rates was assessed for all age groups of infertile women as the difference between fresh cycle live births with reference to number of initiated fresh cycles (excluding embryo banking cycles), as typically reported by the CDC, and fresh cycle live births with reference to total initiated fresh ART cycles (including embryo banking cycles). Results During 2013, out of 121,351 fresh non-donor ART cycles 27,564 (22.7%) involved embryo banking. The proportion of banking cycles increased with female age from 15.5% in women <35 years to 56.5% in women >44 years. Concomitantly, the proportion of thawed cycles decreased with advancing female age (P <0.0001). Exclusion of embryo banking cycles led to inflation of live birth rates in fresh ART cycles, increasing in size in parallel to advancing female age and utilization of embryo banking, reaching 56.3% in women age >44. The inflation of live birth rates in thawed cycles could not be calculated from the publically available CDC data but appears to be even greater. Conclusions Utilization of embryo banking increased during 2013 with advancing female age, suggesting a potential age selection bias. Exclusion of embryo banking cycles from national ART outcome reports significantly inflated national ART success rates, especially among older women. Précis Exclusion of embryo banking cycles from US National Assisted Reproductive Technology outcome reports significantly inflates reported success rates especially in older women. PMID:27159215

    STUDY QUESTION Do women who give birth after assisted reproductive technology (ART) have an increased risk of cancer compared with women who give birth without ART? SUMMARY ANSWER Without correction, the results indicate an increase in overall cancer risk, as well as a 50% increase in risk of CNS cancer for women giving birth after ART, however the results were not significant after correcting for multiple analyses. WHAT IS KNOWN ALREADY Studies regarding the effects of hormonal treatments involved with ART on subsequent cancer risk have provided inconsistent results, and it has also been suggested that infertility itself could be a contributory factor. STUDY DESIGN, SIZE, DURATION A population-based cohort consisting of all women registered in the Medical Birth Registry of Norway as having given birth between 1 January 1984 and 31 December 2010 was assembled (n = 812 986). Cancers were identified by linkage to the Cancer Registry of Norway. Study subjects were followed from start of first pregnancy during the observational period until the first cancer, death, emigration, or 31 December 2010. PARTICIPANTS/MATERIALS, SETTING, METHODS Of the total study population (n = 806 248), 16 525 gave birth to a child following ART. Cox regression analysis computed hazard ratios (HR) and 95% confidence intervals (CI) comparing cancer risk between ART women and non-ART women; for overall cancer, and for cervical, ovarian, uterine, central nervous system (CNS), colorectal and thyroid cancers, and for malignant melanoma. MAIN RESULTS AND THE ROLE OF CHANCE A total of 22 282 cohort members were diagnosed with cancer, of which 338 were ART women and 21 944 non-ART women. The results showed an elevated risk in one out of seven sites for ART women. The HR for cancer of the CNS was 1.50 (95% CI 1.03– 2.18), and among those specifically subjected to IVF (without ICSI) the HR was 1.83 (95% CI 1.22–2.73). Analysis of risk of overall cancer gave an HR of 1.16 (95% CI 1.04–1

    2013-01-01

    This paper analyses the disparities in risks associated with biomedical technology focusing on the results of assisted reproductive technology (ART). ART among biomedical technologies transferred to Asia is a representative case that reveals in its clinical use and related scientific research the global politics of technology. This study notes the global politics at work in the recognition of and reaction to such risks. While many Asian countries aggressively pursue technological development, weak legislative and administrative regulations have created various problems and controversial cases. This study asserts that risks associated with technology are characterised as social facts not natural ones or mere 'side effects', since technological development and risk are closely intertwined.

    Objectives. We assessed the association between assisted reproductive technology (ART) and diagnosed autistic disorder in a population-based sample of California births. Methods. We performed an observational cohort study using linked records from the California Birth Master Files for 1997 through 2007, the California Department of Developmental Services autism caseload for 1997 through 2011, and the Centers for Disease Control and Prevention’s National ART Surveillance System for live births in 1997 through 2007. Participants were all 5 926 251 live births, including 48 865 ART-originated infants and 32 922 cases of autism diagnosed by the Department of Developmental Services. We compared births originated using ART with births originated without ART for incidence of autism. Results. In the full population, the incidence of diagnosed autism was twice as high for ART as non-ART births. The association was diminished by excluding mothers unlikely to use ART; adjustment for demographic and adverse prenatal and perinatal outcomes reduced the association substantially, although statistical significance persisted for mothers aged 20 to 34 years. Conclusions. The association between ART and autism is primarily explained by adverse prenatal and perinatal outcomes and multiple births. PMID:25790396

    The aim of this study was to determine whether homocysteine (hcy) concentrations in embryo culture media correlate with pregnancy outcome in assisted reproductive technology (ART) cycles. Forty patients who underwent single embryo transfer at the infertility clinic of a tertiary care center were recruited for this case-control study. Spent embryo culture media from all patients were collected after single embryo transfer on day 3 (n = 40). Hcy concentrations in embryo culture media were analyzed by enzyme cycling method. Patients were grouped according to the diagnosis of a clinical pregnancy. Sixteen patients were pregnant while 24 patients failed to achieve conception. Mean Hcy levels in the culture media were significantly different between the groups (p < 0.003), as 4.58 ± 1.31 μmol/l in the non-pregnant group and 3.37 ± 0.92 μmol/l in the pregnant group. Receiver operator curve analysis for determining the diagnostic potential of Hcy for pregnancy revealed an area under the curve of 0.792 (confidence interval: 0.65-0.94; p < 0.05). A cut-off value of 3.53 μmol/l was determined with a sensitivity of 83.3%, and a specificity of 68.8%. Lower hcy levels were associated with a better chance of pregnancy and better embryo grades. Hcy may be introduced as an individual metabolomic profiling marker for embryos.

    Objective To study the relation of dietary phytoestrogens intake and clinical outcomes of women undergoing infertility treatment with assisted reproductive technology (ART). Design Prospective cohort study. Setting Fertility center in an academic hospital. Participants 315 women who collectively underwent 520 ART cycles between 2007 and 2013. Interventions None Outcomes Primary outcomes were implantation, clinical pregnancy and live birth rates per initiated cycle. Results Soy isoflavones intake was positively related to live birth rates in ART. Compared to women who did not consume soy isoflavones, the multivariable-adjusted odds ratios of live birth (95% confidence interval) for women in increasing categories of soy isoflavone intake were 1.32 (0.76–2.27) for women consuming 0.54–2.63 mg/d, 1.87 (1.12–3.14) for women consuming 2.64- 7.55 mg/d, and 1.77 (1.03–3.03) for women consuming 7.56- 27.89 mg/d. Conclusions Dietary soy intake was positively related to the probability of having a live birth during infertility treatment with ART. PMID:25577465

    Current RFID technology deployment is limited by safety, procedural and physical limitations in healthcare field. It is important to define and ensure safe operation of technologies without actual deployment in real operation. Potential problems could arise due to the consequences of technical and physical characteristics of RFID technology and its improper location. This article deals with manipulation of blood products and the definition of suitable places for radio identification. Each suitable place must undergo laboratory experiments and tests. The results can provide a convenient base for defining efficient and safe deployment of RFID technology in Blood Centers with substantial financial savings for Czech healthcare.

    In this work, we studied the main characteristics of flowering, reproductive system and diversity of pollinators for the biofuel plant Jatropha curcas (L.) in a site of tropical southeastern Mexico, within its center of origin. The plants were monoecious with inflorescences of unisexual flowers. The male flowers produced from 3062-5016 pollen grains (266-647 per anther). The plants produced fruits with both geitonogamy and xenogamy, although insect pollination significantly increased the number and quality of fruits. A high diversity of flower visiting insects (36 species) was found, of which nine were classified as efficient pollinators. The native stingless bees Scaptotrigona mexicana (Guérin-Meneville) and Trigona (Tetragonisca) angustula (Latreille) were the most frequent visitors and their presence coincided with the hours when the stigma was receptive. It is noteworthy that the female flowers open before the male flowers, favoring xenogamy, which may explain the high genetic variability reported in J. curcas for this region of the world.

    The Center's primary function is to facilitate technology transfer within DoD, other government agencies and industry. The DoD has recognized the importance of technology transfer, not only to support specific weapon system manufacture, but to strengthen the industrial base that sustains DoD. MTIAC uses an experienced technical staff of engineers and information specialists to acquire, analyze, and disseminate technical information. Besides ManTech project data, MTIAC collects manufacturing technology from other government agencies, commercial publications, proceedings, and various international sources. MTIAC has various means of disseminating this information. Much of the technical data is on user accessible data bases. The Center researches and writes a number of technical reports each year and publishes a newsletter monthly. Customized research is performed in response to specific inquiries from government and industry. MTIAC serves as a link between Government and Industry to strengthen the manufacturing technology base through the dissemination of advanced manufacturing information.

    This article tracks the growth of medical anthropology in the United States in the decades since the 1970s, as it has intersected the expansion of feminist activism and scholarship. I argue that feminist attention to embodied inequalities quickly focused on reproduction as a site of investigation and intervention. Medical anthropology has benefited from feminist concern with stratified reproduction, especially its interrogation of nonnormative and stigmatized fertility and childbearing. When reproduction becomes problematic, it provides a lens through which cultural norms, struggles, and transformations can be viewed. Examples drawn from prenatal diagnosis are particularly revelatory of the diverse interests and stakes we all hold in reproduction. PMID:11794871

  19. How maya women respond to changing technology : The effect of helping behavior on initiating reproduction.

    Kramer, K L; McMillan, G P

    1998-06-01

    In the mid 1970s labor-saving technology was introduced into a Maya subsistence agricultural community that markedly increased the efficiency with which maize could be ground and water collected. This increased efficiency introduces a possible savings in the time that women allocate to work, which can be reapportioned to child care, food production, domestic work, or leisure. An earlier study suggested that this labor-saving technology had a positive effect in decreasing the age at which these Maya women begin their reproductive careers. Although there is a statistical association between the age at which women bear their first child and the introduction of modern technology, this association does not demonstrate that the decline in age at first birth is causally related to the presence of technology. This paper pursues two objectives to evaluate this potential causal relationship in greater detail. First, a theory relating technological change to the initiation of a reproductive career is briefly developed in order to make qualitative predictions about behavioral changes as a response to changing technology. Second, these predictions are then tested against time allocation data recently collected in this same Maya community.We suggest that both of the conditions necessary to initiate reproduction-fecundity and access to mates-fundamentally depend on the amount of help that a girl provides to her family. Further, the help that a girl provides can be affected by technological changes. Analyses show that when modern technology is available, unmarried young women do not change the time allocated to domestic tasks and child care, and allocate more time to low-energy leisure activities. This lack of perceived benefit to working more and a potential concomitant shift towards a positive energy balance may in part explain why Maya women leave home and initiate reproduction at a younger age after labor-saving technology is introduced.

    Stirling Radioisotope Power Systems (RPS) are under development to provide power on future space science missions where robotic spacecraft will orbit, flyby, land or rove using less than a quarter of the plutonium the currently available RPS uses to produce about the same power. Glenn Research Center's (GRC's) newly formulated Stirling Cycle Technology Development Project (SCTDP) continues development of Stirling-based systems and subsystems, which include a flight-like generator and related housing assembly, controller, and convertors. The project also develops less mature technologies under Stirling Technology Research, with a focus on demonstration in representative environments to increase the technology readiness level (TRL). Matured technologies are evaluated for selection in future generator designs. Stirling Technology Research tasks focus on a wide variety of objectives, including increasing temperature capability to enable new environments, reducing generator mass and/or size, improving reliability or system fault tolerance, and developing alternative designs. The task objectives and status are summarized.

    2013-06-01

    This review provides an update on what is currently known about wombat reproductive biology and reports on attempts made to manipulate and/or enhance wombat reproduction as part of the development of artificial reproductive technology (ART) in this taxon. Over the last decade, the logistical difficulties associated with monitoring a nocturnal and semi-fossorial species have largely been overcome, enabling new features of wombat physiology and behaviour to be elucidated. Despite this progress, captive propagation rates are still poor and there are areas of wombat reproductive biology that still require attention, e.g. further characterisation of the oestrous cycle and oestrus. Numerous advances in the use of ART have also been recently developed in the Vombatidae but despite this research, practical methods of manipulating wombat reproduction for the purposes of obtaining research material or for artificial breeding are not yet available. Improvement of the propagation, genetic diversity and management of wombat populations requires a thorough understanding of Vombatidae reproduction. While semen collection and cryopreservation in wombats is fairly straightforward there is currently an inability to detect, induce or synchronise oestrus/ovulation and this is an impeding progress in the development of artificial insemination in this taxon.

    The successful development and application of an assisted breeding program in any animal relies primarily on a thorough understanding of the fundamental reproductive biology (anatomy, physiology and behaviour) of the species in question. Surely, the ultimate goal and greatest hallmark of such a program is the efficacious establishment of a series of reliable techniques that facilitate the reproductive and genetic management of fragmented populations, both in captivity and in the wild. Such an achievement is all the more challenging when the reproductive biology of that species is essentially rudimentary and without adequate reproductive models to compare to. Using the koala (Phascolarctos cinereus) as a case study, this chapter provides some personal insights into the evolution of a concept that began as a small undergraduate student project but that subsequently evolved into the first-ever successful artificial insemination of a marsupial. Apart from this historical perspective, we also provide a brief review of the current reproductive biology of the koala, discuss technical elements of current assisted breeding technology of this species, its potential application to the wombat, and the future role it might play in helping to conserve wild koala populations. There is little doubt that the unique reproductive biology and tractability of the koala has in this case been a benefit rather than a hindrance to the success of artificial breeding in this species.

    2015-01-01

    OBJECTIVE To estimate trends in good perinatal outcomes (singleton live births at term with birthweight more than 2,500 g) among live births after assisted reproductive technology in the United States from 2000 to 2008, and associated factors among singletons in 2008. METHODS Using retrospective cohort data from the National Assisted Reproductive Technology Surveillance System from 2000 to 2008, we calculated relative change and χ2 tests for trend in the proportion of good perinatal outcomes among assisted reproductive technology live births (n=444,909) and liveborn singletons (n=222,500). We conducted univariable analyses followed by multiple logistic regression to estimate the effects of various characteristics on the outcome among singletons born in 2008 after fresh, nondonor assisted reproductive technology cycles (n=20,780). RESULTS The proportion of good perinatal outcomes among all liveborn neonates increased from 38.6% in 2000 to 42.5% in 2008, whereas it declined marginally among singletons from 83.6% to 83.4%. One previous birth, transfer of fewer than three embryos, and the presence of fewer than three fetal hearts on 6-week ultrasound examination were associated with good perinatal outcome among singletons. Non-Hispanic black race, tubal factor infertility, uterine factor infertility, ovulatory disorder, and 5-day embryo culture were associated with reduced odds for a good outcome. The strongest association was the presence of one fetal heart compared with more than two (adjusted odds ratio 2.43, 95% confidence interval 1.73–3.42). CONCLUSION From 2000 to 2008, good perinatal outcomes increased among assisted reproductive technology live births. Among singleton live births, odds for good outcome were greatest with the presence of a single fetal heart and lowest in women of non-Hispanic black race. LEVEL OF EVIDENCE: II PMID:22996102

    1994-12-31

    The challenges posed by remediating closing bases offers a special opportunity for California`s environmental technology companies, former defense contractors and Californians in general. One of the most important factors in the successful remediation and reuse of closing bases is the development of new cleanup technologies. At present, there is no method for effectively remediating some kinds of contamination found at military bases. Cal/EPA is in the process of working with the Western Governors` Association Wastes at Military Bases Workgroup to create a strategic plan that will integrate federal, state and local technology development programs. The proposed strategic plan will include a blueprint to help guide proposed technology development centers in California to a portion of the market yet to be addressed by other centers within the state, thus eliminating intra-state competition for the same market. By addressing this issue in a proactive manner, California will demonstrate to the federal government that tax dollars utilized to support technology development centers sited at closing California bases will be present in an efficient and cost effective manner.

    The aim of the article was to investigate the relationship between pregnancy complications, infertility and assisted reproductive technologies (ART). The study was conducted on 1331 couples with complicated reproductive history. It is found that miscarriage and other complications of pregnancy depend rather on the etiopathogenesis of infertility than on the technique of ART. The highest frequency of complications of pregnancy was diagnosed in women with endocrine disorders. In case of congenital malformations in the fetus the frequency of birth defects was 3.6% after in vitro fertilization (IVF) and 1.8% in case of spontaneous pregnancy. It was found an increased risk of birth defects in singleton boys conceived by IVF.

    Background Personality traits affect human relationships, social interactions, treatment procedures, and essentially all human activities. The purpose of this study is to investigate the personality traitsincluding sensation seeking, flexibility, and happiness among a variety of infertile women who were apt to choose assisted reproductive technology (ART) or surrogacy. Materials and Methods This is a cross-sectional study that was performed on 251 infertile women who visited Isfahan and Tehran Reproductive Medicine Center. These fertility clinics are located in Isfahan and Tehran, Iran. In this study, 201 infertile women who underwent treatment using ART and 50 infertile women who tended to have surrogacy were chosen by convenience sampling. Zuckerman’s Sensation Seeking Scale Form V (SSS-V), Psychological Flexibility Questionnaire (adapted from NEO Personality Inventory-Revised) and Oxford Happiness Questionnaire (OHQ) were used as research instruments. All participants had to complete the research instruments in order to be included in this study. Data were analyzed by descriptive-analytical statistics and statistical tests including multivariate analysis of variance (MANOVA) and Z Fisher. Statistically significant effects were accepted for P<0.05. Results In the sensation-seeking variable, there was a meaningful difference between under-study groups. However, the flexibility and happiness variables did not have a significant difference between under-study groups (P<0.001). Interaction between education, employment, and financial status was effective in happiness of infertile women underwent ART (P<0.05), while age, education and financial status were also effective in happiness of infertile women sought surrogacy (P<0.05). A positive meaningful relationship was seen between sensation seeking and flexibility variables in both groups (P<0.05). And a negative meaningful relationship was seen between sensation seeking and happiness in infertile women who sought

    Mid-atlantic Technology Application Center (MTAC) pursued a number of initiatives designed to enhance the strategic position of the Langley Research Center (LaRC) and NASA in industry. Among these was a closer association with the ISA, International Society for Measurement and Control. During 1997, MTAC placed articles regarding NASA-developed technologies in each In Tech magazine. The monthly magazine is sent to 46,000 sensors and instrumentation professionals. In addition, MTAC coordinated NASXs participation in the ISA Tech 97 Conference, securing $112,000 of free exhibit space, 1500 NASA sensors posters at no cost to NASA, and thousands of dollars of free publicity. MTAC was awarded a contract by ISA to operate its Technical Resource Center (TRC). The goal of this project is to determine what user needs are in order to identify opportunities for collaboration between NASA centers and companies. In addition, the TRC work will lay the groundwork for the Technology Development Consortium (TDC) proposed by MTAC. The purpose of the TDC is to: match current industry needs with NASA technologies available now, and to identify future needs of NASA and industry which may lead to dual use projects. The goal of these activities is twofold: to infuse NASA technologies into the sensors and instrumentation industry and to secure industry funds to support NASA technology development projects. The instrumentation and sensors industry is valued at $30 billion worldwide, with $12 billion in sales in the United States. The growth rate averages 13.5%, so that by the year 2000, the industry will produce products worth $49 billion. More than 80% of instruments, sensors and control systems are currently manufactured in the United States. NASA and the industry do not have a history of collaborative projects; MTAC's initiatives in this area are designed to foster working relationships between the two parties that will help maintain U.S. leadership in this field.

    The Italian parliament passed the law on assisted reproduction after a heated debate. The promulgation of this law (Law 40/2004) is the end point of a long and troubled journey that has seen many bills come and go, all of which have failed. The law consists of a whole set of regulations that will have a great impact on health and on society in general. The law is against many of the technical practices of assisted reproduction; several such practices are banned. This paper outlines ethical and medicolegal issues arising in connection with the law. The law states that no more than three embryos must be created at any one time and all the embryos created must be transferred together even if the couple does not need all the embryos. Embryo cryopreservation is also forbidden, as is assisted reproductive technology (ART), which uses a third party in any way, and the screening of embryos for genetic defects. PMID:16131556

    2014-01-01

    Reproductive technologies have dramatically changed the way pigs are raised for pork production in developed and developing countries. This has involved such areas as pigs produced/sow, more consistent pig flow to market, pig growth rate and feed efficiency, carcass yield and quality, labor efficiency, and pig health. Some reproductive technologies are in widespread use for commercial pork operations [Riesenbeck, Reprod Domest Anim 46:1-3, 2011] while others are in limited use in specific segments of the industry [Knox, Reprod Domest Anim 46:4-6, 2011]. Significant changes in the efficiency of pork production have occurred as a direct result of the use of reproductive technologies that were intended to improve the transfer of genes important for food production [Gerrits et al., Theriogenology 63:283-299, 2005]. While some technologies focused on the efficiency of gene transfer, others addressed fertility and labor issues. Among livestock species, pig reproductive efficiency appears to have achieved exceptionally high rates of performance (PigCHAMP 2011) [Benchmark 2011, Ames, IA, 12-16]. From the maternal side, this includes pigs born per litter, farrowing rate, as well as litters per sow per year. On the male side, boar fertility, sperm production, and sows served per sire have improved as well [Knox et al., Theriogenology, 70:1202-1208, 2008]. These shifts in the efficiency of swine fertility have resulted in the modern pig as one of the most efficient livestock species for global food production. These reproductive changes have predominantly occurred in developed countries, but data suggests transfer and adoption of these in developing countries as well (FAO STAT 2009; FAS 2006) [World pig meat production: food and agriculture organization of the United Nations, 2009; FAS, 2006) Worldwide Pork Production, 2006].

    The present research effort was the first phase of a study to forecast whether technological obsolescence will be a problem for the engineers, scientists, and technicians at NASA Langley Research Center (LaRC). There were four goals of the research: to review the literature on technological obsolescence; to determine through interviews of division chiefs and branch heads Langley's perspective on future technological obsolescence; to begin making contacts with outside industries to find out how they view the possibility of technological obsolescence; and to make preliminary recommendations for dealing with the problem. A complete description of the findings of this research can be reviewed in a technical report in preparation. The following are a small subset of the key findings of the study: NASA's centers and divisions vary in their missions and because of this, in their capability to control obsolescence; research-oriented organizations within NASA are believed by respondents to keep up to date more than the project-oriented organizations; asked what are the signs of a professional's technological obsolescence, respondents had a variety of responses; top performing scientists were viewed as continuous learners, keeping up to date by a variety of means; when asked what incentives were available to aerospace technologists for keeping up to data, respondents specified a number of ideas; respondents identified many obstacles to professionals' keeping up to date in the future; and most respondents expressed some concern for the future of the professionals at NASA vis a vis the issue of professional obsolescence.

    In recent years, the development of aerodynamic technology for rotorcraft has continued successfully at NASA LaRC. Though the NASA Langley Research Center is not the lead NASA center in this area, the activity was continued due to facilities and individual capabilities which are recognized as contributing to helicopter research needs of industry and government. Noteworthy accomplishments which contribute to advancing the state of rotorcraft technology in the areas of rotor design, airfoil research, rotor aerodynamics, and rotor/fuselage interaction aerodynamics are described. Rotor designs were defined for current helicopters and evaluated in wind tunnel testing. These designs have incorporated advanced airfoils defined analytically and also proven in wind tunnel tests. A laser velocimetry system has become a productive tool for experimental definition of rotor inflow/wake and is providing data for rotorcraft aerodynamic code validation.

    In January 2005, the Assisted Reproductive Technologies (ART) Workshop: Evaluation of Genetic and Epigenetic Risks Associated with Assisted Reproductive Technologies and Infertility was convened to evaluate current data on genetic and epigenetic risks to offspring conceived after a period of infertility and/or via ARTs. Formal presentations and workshop breakout groups reviewed the information from a broad range of disciplines and discussed issues regarding study design, molecular approaches, animal model systems, clinical outcomes, and ethical, legal, and psychosocial issues. The key recommendations of the workshop are that: [1] ART research and education should flow from clinical and basic science studies of the fundamental biology of early mammalian embryonic development, with a focus on how infertility and/or ART might disrupt such processes; [2] such research should include the emerging area of epigenetics and its potential role in reproductive health outcomes; [3] methods for the standardization of data collection and for handling and analysis should be employed, including precise definitions of obstetric and perinatal terminology; [4] much greater awareness and ongoing evaluation of the psychosocial impact of ART and ART research on women, their partners, and their offspring are required; and [5] effective methods of knowledge transfer need to be developed and delivered to healthcare providers and to the general public regarding reproductive planning, infertility, and ART, including the potential risks associated with each.

    Funding will support the continuation of the Center for Advanced Bio-based Binders and Pollution Reduction Technology Center (CABB) in the development of bio-based polymers and emission reduction technologies for the metal casting industry. Since the formation of the center several new polymers based on agricultural materials have been developed. These new materials have show decreases in hazardous air pollutants, phenol and formaldehyde as much as 50 to 80% respectively. The polymers termed bio-polymers show a great potential to utilize current renewable agricultural resources to replace petroleum based products and reduce our dependence on importing of foreign oil. The agricultural technology has shown drastic reductions in the emission of hazardous air pollutants and volatile organic compounds and requires further development to maintain competitive costs and productivity. The project will also research new and improved inorganic binders that promise to eliminate hazardous emissions from foundry casting operations and allow for the beneficial reuse of the materials and avoiding the burdening of overcrowded landfills.

Over the past year we have offered three teacher professional development workshops that showcase NASA Lewis-developed educational products and NASA educational Internet sites. In order to determine the direction of our involvement with distance learning, the LTP staff conducted a survey of 500 U.S. schools. We received responses from 72 schools that either currently use distance learning or will be using distance learning in 98-99 school year. The results of the survey are summarized in the article. In addition, the article provides information on distance learners, distance learning technologies, and the NASA Lewis LTP videoconferencing workshops. The LTP staff will continue to offer teacher development workshops through videoconferencing during the 98-99 school year. We hope to add workshops on new educational products as they are developed at NASA Lewis.

    Academic culture has a set of norms, expectations, and values that are sometimes tacit and sometimes very explicit. In medical school and other health professions educational settings, probably the most common norm includes placing a high value on peer-reviewed research publications, which are seen as the major evidence of scholarly productivity. Other features of academic culture include encouraging junior faculty and graduate students to share their research results at professional conferences and lecturing with slides as a major way to convey information. Major values that faculty share with journal editors include responsible conduct of research and proper attribution of others' words and ideas. Medical school faculty also value technology and are often quick to embrace technological advances that can assist them in their teaching and research. This article addresses the effects of technology on three aspects of academic culture: education, presentations at professional meetings, and research publications.The technologies discussed include online instruction, dissemination of conference proceedings on the Internet, plagiarism-detection software, and new technologies deployed by the National Center for Biotechnology Information, the home of PubMed. The author describes how the ease of deploying new technologies without faculty changing their norms and behavior in the areas of teaching and research can lead to conflicts of values among key stakeholders in the academic medical community, including faculty, journal editors, and professional associations. The implications of these conflicts and strategies for managing them are discussed.

    Estimations of world population growth indicate that by the year 2050 we will reach nine billion habitants on earth. These estimates impose a tremendous challenge in the current agricultural systems as food supply will need to increase by 100 % in the next 40 years (Food and Agriculture Organization of the United Nations 2009). Beef will be a primary protein source that will assist in meeting the requirements for a portion of the protein in diets of this expanding global populace. Beef is a high-quality protein that contains all essential amino acids for the human body and also contains additional essential nutrients such as iron, zinc, B vitamins, riboflavin, selenium, choline, and conjugated linoleic acid (CLA). Adopting reproductive technologies at greater rates than currently used is a viable method to dramatically enhance production efficiency of beef cattle enterprises.Artificial insemination (AI), estrous synchronization and fixed-time AI (TAI), semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of beef operations. In many cases, the development of these technologies is responsible for significant changes to traditional livestock production practices. However, adoption of these technologies appears to has not grown at the same rate in the United States as other formidable beef producing nations. For example, sales of beef semen for AI increased from 3.3 to 11.9 million units between 1993 and 2011 in Brazil, whereas that in the United States has increased from 2.9 to 3.8 million units during the same period. The significant increases in adoption of reproductive technologies in developing countries is likely as a result of the development of practical estrous synchronization and TAI systems that have allowed beef producers the opportunity to eliminate detection of estrus in their

    Creation of both gametes, sperm and oocyte, and their fusion during fertilization are essential step for beginning of life. Although molecular mechanisms regulating gametogenesis, fertilization, and early embryonic development are still subjected to intensive study, a lot of phenomena remain unclear. Based on our best knowledge and own results, we consider gasotransmitters to be essential for various signalisation in oocytes and embryos. In accordance with nitric oxide (NO) and hydrogen sulfide (H2S) physiological necessity, their involvement during oocyte maturation and regulative role in fertilization followed by embryonic development have been described. During these processes, NO- and H2S-derived posttranslational modifications represent the main mode of their regulative effect. While NO represent the most understood gasotransmitter and H2S is still intensively studied gasotransmitter, appreciation of carbon monoxide (CO) role in reproduction is still missing. Overall understanding of gasotransmitters including their interaction is promising for reproductive medicine and assisted reproductive technologies (ART), because these approaches contend with failure of in vitro assisted reproduction.

    The escalation of Assisted Reproductive Technologies (ARTs) in India into a veritable fertility industry is the result of a multitude of reasons. This paper places the bio-genetic industry within the larger political economy framework of globalisation and privatisation, thus employing a framework that is often omitted from discussions on ARTs, but has direct and significant bearings on the ART industry in India. As markets for human organs, tissues and reproductive body parts experience unprecedented growth, the limits of what can or should be bought and sold continue to be pushed. As such, bodies have emerged as sale-worthy economic capital. Commercial flows of reproductive material create and deploy the division of the body into parts over which ownership is claimed, in the process following 'modern routes of capital' and raising issues of structural inequality.This paper presents a brief picture of India's fertility industry with specific focus on its ground-level operation, nature and growth. It aims to explore the industry dimensions of ARTs, by highlighting the macro picture of health care markets and medical tourism in India, the proliferation of the ART industry, market features such as the social imperative to mother, costs, promotion and marketing, unverified claims, inflated success rates, deals and offers, actors and collaborations in the field, and finally, the absence of standards.

    The Small Business Innovation Research (SBIR) Program increases opportunities for small businesses to participate in research and development (R&D), increases employment, and improves U.S. competitiveness. Specifically the program stimulates U.S. technological innovation by using small businesses to meet federal R&D needs, increasing private-sector commercialization of innovations derived from federal R&D, and fostering and encouraging the participation of socially disadvantaged businesses. In 2000, the Small Business Technology Transfer (STTR) Program extended and strengthened the SBIR Program, increasing its emphasis on pursuing commercial applications by awarding contracts to small business concerns for cooperative R&D with a nonprofit research institution. Modeled after the SBIR Program, STTR is nevertheless a separately funded activity. Technologies that have resulted from the Johnson Space Center SBIR STTR Program include: a device for regenerating iodinated resin beds; laser-assisted in-situ keratomileusis or LASIK; a miniature physiological monitoring device capable of collecting and analyzing a multitude of real-time signals to transmit medical data from remote locations to medical centers for diagnosis and intervention; a new thermal management system for fibers and fabrics giving rise to new line of garments and thermal-enhancing environments; and a highly electropositive material that attracts and retains electronegative particles in water.

    A new cryogenic optical testing capability exists at Marshall Space Flight Center's Space Optics Manufacturing Technology Center (SOMTC). SOMTC has been performing optical wavefront testing at cryogenic temperatures since 1999 in the X-ray Cryogenic Test Facility's (XRCF's) large vacuum chamber. Recently the cryogenic optical testing capability has been extended to a smaller vacuum chamber. This smaller horizontal cylindrical vacuum chamber has been outfitted with a helium-cooled liner that can be connected to the facility's helium refrigeration system bringing the existing kilowatt of refrigeration capacity to bear on a 1 meter diameter x 2 meter long test envelope. Cryogenic environments to less than 20 Kelvin are now possible in only a few hours. SOMTC's existing instruments (the Instantaneous Phase-shifting Interferometer (IPI) from ADE Phase-Shift Technologies and the PhaseCam from 4D Vision Technologies) view the optic under test through a 150 mm clear aperture BK-7 window. Since activation and chamber characterization tests in September 2001, the new chamber has been used to perform a cryogenic (less than 30 Kelvin) optical test of a 22.5 cm diameter x 127 cm radius of curvature SiO2 mirror, a cryogenic survival (less than 30 Kelvin) test of an adhesive, and a cryogenic cycle (less than 20 Kelvin) test of a ULE mirror. A vibration survey has also been performed on the test chamber. Chamber specifications and performance data, vibration environment data, and limited test results will be presented.

  10. Building Irish families through surrogacy: medical and judicial issues for the advanced reproductive technologies

    2008-01-01

    Surrogacy involves one woman (surrogate mother) carrying a child for another person/s (commissioning person/couple), based on a mutual agreement requiring the child to be handed over to the commissioning person/couple following birth. Reasons for seeking surrogacy include situations where a woman has non-functional or absent reproductive organs, or as a remedy for recurrent pregnancy loss. Additionally, surrogacy may find application in any medical context where pregnancy is contraindicated, or where a couple consisting of two males seek to become parents through oocyte donation. Gestational surrogacy is one of the main issues at the forefront of bioethics and the advanced reproductive technologies, representing an important challenge to medical law. This analysis reviews the history of surrogacy and clinical and legal issues pertaining to this branch of reproductive medicine. Interestingly, the Medical Council of Ireland does not acknowledge surrogacy in its current practice guidelines, nor is there specific legislation addressing surrogacy in Ireland at present. We therefore have developed a contract-based model for surrogacy in which, courts in Ireland may consider when confronted with a surrogacy dispute, and formulated a system to resolve any potential dispute arising from a surrogacy arrangement. While the 2005 report by the Commission on Assisted Human Reproduction (CAHR) is an expert opinion guiding the Oireachtas' development of specific legislation governing assisted human reproduction and surrogacy, our report represents independent scholarship on the contractual elements of surrogacy with particular focus on how Irish courts might decide on surrogacy matters in a modern day Ireland. This joint medico-legal collaborative also reviews the contract for services arrangement between the commissioning person/s and the surrogate, and the extent to which the contract may be enforced.

    Despite the prominence of the disability civil rights model--with its values of inclusion and empowerment--the majority of social and policy research conducted to date has not sufficiently included the perspective of persons with disabilities in the research process and as uniquely qualified researchers themselves. This article describes a new project, "Technology for Independence: A Community-Based Resource Center" (CBRC). Over a five-year period, the CBRC will attempt to enhance community and consumer-directed disability organizations to design, implement, and disseminate research that promotes access to and use of assistive technology (AT). The CBRC will use strategies such as leadership training, participatory action research, technical assistance, web-assisted training, and annual symposia. A primary goal of the CBRC is to increase the capacity of community organizations to conduct research on AT that is scientifically rigorous and relevant to disability services, policy, and law.

    2012-08-01

    With the benefits of automation, sensitivity and precision, microfluidics has enabled complex and otherwise tedious experiments. Lately, lab-on-a-chip (LOC) has proven to be a useful tool for enhancing non-invasive assisted reproductive technology (ART). Non-invasive gamete and embryo assessment has largely been through periodic morpohological assessment using optical microscopy and early LOC ART was the same. As we realize that morphological assessment is a poor indication of gamete or embryo health, more advanced biophotonics has emerged in LOC ART to assay for metabolites or gamete separation via optoelectrical tweezers. Off-chip, even more advanced biophotonics with broad spectrum analysis of metabolites and secretomes has been developed that show even higher accuracy to predicting reproductive potential. The integration of broad spectrum metabolite analysis into LOC ART is an exciting future that merges automation and sensitivity with the already highly accurate and strong predictive power of biophotonics.

    The success of assisted reproductive technologies relies on accurate assessment of reproductive viability at successive stages of development for oocytes and embryos. The current scoring system used to select good-quality oocytes relies on morphologically observable traits and hence is indirect and subjective. Biodynamic imaging may provide an objective approach to oocyte and embryo assessment by measuring physiologically-relevant dynamics. Biodynamic imaging is a coherence-gated approach to 3D tissue imaging that uses digital holography to perform low-coherence speckle interferometry to capture dynamic light scattering from intracellular motions. The changes in intracellular activity during cumulus oocyte complex maturation, before and after in vitro fertilization, and the subsequent development of the zygote and blastocyst provide a new approach to the assessment of preimplant candidates.

  15. Impact of reproductive technologies on dairy food production in the dairy industry.

    Stevenson, Jeffrey S

    2014-01-01

    Reproductive technologies drive the efficiency of managing dairy cows because the lactation cycle of the dairy cow depends on regular calving to renew lactation yields. Achieving timely pregnancies to allow calving every 12-14 months, therefore, is critical in modern dairy production. To meet the demands to produce sufficient milk for fluid and dairy products, various technologies are applied to enhance efficiencies on the dairy farm. Artificial insemination (AI), embryo transfer, ultrasonographic and chemical detection of pregnancy, various monitors that detect or predict estrus, and handheld communication and testing devices allow managers to retrieve information to make cow-side decisions about health and reproductive status. Genomic testing of young potential sires or young heifers is now possible and can provide information about their genetic merit years before any progeny tests can be completed. In many countries, the challenge faced by dairy producers is their ability to afford these technologies in the face of rising feed and labor costs and volatile milk prices received at the farm gate. Government policies often place obstacles, trade barriers, and unfunded mandates that preclude operations from making a modest profit. Unlike nearly all other manufacturing industries, agriculture producers have little control over the price received for their products. Therefore, dairy production is vulnerable to many uncontrolled factors including climate, government policy, economic conditions, and skilled labor shortages. It is clear that the impact of emerging and current reproductive technologies is critical to the management of dairy cattle to produce sufficient milk to meet consumer demands for quality fluid and dairy products.

    1989-01-01

    Much of the technology planned for use in NASA's Flight Telerobotic Servicer (FTS) and the Demonstration Test Flight (DTF) is relatively new and untested. To provide the answers needed to design safe, reliable, and fully functional robotics for flight, NASA/GSFC is developing a robotics technology testbed for research of issues such as zero-g robot control, dual arm teleoperation, simulations, and hierarchical control using a high level programming language. The testbed will be used to investigate these high risk technologies required for the FTS and DTF projects. The robotics technology testbed is centered around the dual arm teleoperation of a pair of 7 degree-of-freedom (DOF) manipulators, each with their own 6-DOF mini-master hand controllers. Several levels of safety are implemented using the control processor, a separate watchdog computer, and other low level features. High speed input/output ports allow the control processor to interface to a simulation workstation: all or part of the testbed hardware can be used in real time dynamic simulation of the testbed operations, allowing a quick and safe means for testing new control strategies. The NASA/National Bureau of Standards Standard Reference Model for Telerobot Control System Architecture (NASREM) hierarchical control scheme, is being used as the reference standard for system design. All software developed for the testbed, excluding some of simulation workstation software, is being developed in Ada. The testbed is being developed in phases. The first phase, which is nearing completion, and highlights future developments is described.

    Nearly all industrial facilities have been responsible for introducing synthetic chemicals into the environment. The Savannah River Site is no exception. Several areas at the site have been contaminated by chlorinated volatile organic chemicals. Because of the persistence and refractory nature of these contaminants, a complete clean up of the site will take many years. A major focus of the mission of the Environmental Sciences Section of the Savannah River Technology Center is to develop better, faster, and less expensive methods for characterizing, monitoring, and remediating the subsurface. These new methods can then be applied directly at the Savannah River Site and at other contaminated areas in the United States and throughout the world. The Environmental Sciences Section has hosted field testing of many different monitoring technologies over the past two years primarily as a result of the Integrated Demonstration Program sponsored by the Department of Energy`s Office of Technology Development. This paper provides an overview of some of the technologies that have been demonstrated at the site and briefly discusses the applicability of these techniques.

    1996-11-01

    The National Renewable Energy Laboratory (NREL), the nation`s primary solar and renewable energy research laboratory, proposes to expand its wind technology research and development program activities at its National Wind Technology Center (NWTC) near Golden, Colorado. NWTC is an existing wind energy research facility operated by NREL for the US Department of Energy (DOE). Proposed activities include the construction and reuse of buildings and facilities, installation of up to 20 wind turbine test sites, improvements in infrastructure, and subsequent research activities, technology testing, and site operations. In addition to wind turbine test activities, NWTC may be used to support other NREL program activities and small-scale demonstration projects. This document assesses potential consequences to resources within the physical, biological, and human environment, including potential impacts to: air quality, geology and soils, water resources, biological resources, cultural and historic resources, socioeconomic resources, land use, visual resources, noise environment, hazardous materials and waste management, and health and safety conditions. Comment letters were received from several agencies in response to the scoping and predecisional draft reviews. The comments have been incorporated as appropriate into the document with full text of the letters contained in the Appendices. Additionally, information from the Rocky Flats Environmental Technology Site on going sitewide assessment of potential environmental impacts has been reviewed and discussed by representatives of both parties and incorporated into the document as appropriate.

    The relationship between information and communication technology (ICT) and trauma work coordination has long been recognized. The purpose of the study was to investigate the type and frequency of use of various ICTs to activate and organize trauma teams in level I/II trauma centers. In a cross-sectional survey, questionnaires were mailed to trauma directors and clinicians in 457 trauma centers in the United States. Responses were received from 254 directors and 767 clinicians. Communication with pre-hospital care providers was conducted predominantly via shortwave radio (67.3%). The primary communication methods used to reach trauma surgeons were manual (56.7%) and computerized group page (36.6%). Computerized group page (53.7%) and regular telephone (49.8%) were cited as the most advantageous devices; e-mail (52.3%) and dry erase whiteboard (52.1%) were selected as the least advantageous. Attending surgeons preferred less overhead paging and more cellular phone communication than did emergency medicine physicians and nurses. Cellular phones have become an important part of hospital-field communication. In high-volume trauma centers, there is a need for more accurate methods of communicating with field personnel and among hospital care providers. PMID:16434331

    The Marshall Space Flight Center is continuing its vigorous efforts in space-related research and technology. Extensive activities in advanced studies have led to the approval of the Orbital Maneuvering Vehicle as a new start. Significant progress was made in definition studies of liquid rocket engine systems for future space transportation needs and the conceptualization of advanced laucnch vehicles. The space systems definition studies have brought the Advanced X-ray Astrophysics Facility and Gravity Probe-B to a high degree of maturity. Both are ready for project implementation. Also discussed include significant advances in low gravity sciences, solar terrestrial physics, high energy astrophysics, atmospheric sciences, propulsion systems, and on the critical element of the Space Shuttle Main Engine in particular. The goals of improving the productivity of high-cost repetitive operations on reusable transportation systems, and extending the useful life of such systems are examined. The research and technology highlighted provides a foundation for progress on the Hubble Space Telescope, the Space Station, all elements of the Space Transportation System, and the many other projects assigned to this Center.

    2014-01-01

    Industries based on small ruminants are major contributors to world food supply but, in extensive grazing systems, reproductive technology is not directly relevant to most enterprises. More important is the need to respond to demand in high-profit export markets for products that are 'clean, green and ethical' (CGE). This combination of issues led to the concept of CGE management of reproduction that is based on scientific evidence but does not require complex technology. Nutrition is the major challenge because we are limited primarily to the grazing of forages and pastures, but responding to this challenge opens up opportunities-new forages can supply energy and protein whilst improving animal health and welfare, and reducing carbon emissions. A second major factor is the need for accurate coordination of nutritional inputs with reproductive events to ensure that the metabolic signals are appropriate. To control of the timing of reproduction, we need to move beyond simply managing the presence of the male and seek more precision. Our ultimate CGE package is thus based on manipulation of male socio-sexual signals as well as nutrition, in combination with greater use of ultrasound and birth-site management to prevent neonatal mortality. Finally, genetics is critical in the development of the CGE package.It would be difficult to incorporate the entire package in one hit-adaptations are needed to cover variations in genotype and the geographical and socio-economic environment, and some concepts need research and development. Therefore, we have suggested staged introduction of the elements of the package.CGE management can be simple and cost-effective, and improve productivity whilst safeguarding the future of the industries in society and the marketplace. Reproductive technology might not be used by many farmers but it will be an essential tool for realizing the vision because it underpins the acceleration of genetic progress in otherwise tardy grazing industries

  6. The German IVF Register as an Instrument to Document Assisted Reproductive Technologies

    2016-01-01

    The German IVF Register (Deutsches IVF-Register [D.I.R]) has been collecting and publishing data on the use of IVF and related methods in Germany since 1982. It is the only institution which provides information for all of Germany on procedures and their success rates. For this reason it plays an important role in the provision of information to the public, to patients, political decision-makers and the scientific community. However, the register does not have the data of all centers offering treatment in Germany nor does it have complete datasets on all reported treatments. The register accepts retrospective data entries, it does not publish the success rates of individual centers and up until 2015 it did not provide a summary of information which was suitable for non-specialists. The D.I.R has been the focus of criticism in the past. Even today, the information it provides to the scientific community, the public, political decision-makers and potential patients on the outcomes of assisted reproduction is insufficient. The documentation of reproductive medicine procedures in other countries is much more meaningful. PMID:27365538

    1997-01-01

    An overview of NASA's Mars Pathfinder Program is given and the development and role of three technology experiments from NASA's Lewis Research Center and carried on the Mars Pathfinder rover is described. Two recent missions to Mars were developed and managed by the Jet Propulsion Laboratory, and launched late last year: Mars Global Surveyor in November 1996 and Mars Pathfinder in December 1996. Mars Global Surveyor is an orbiter which will survey the planet with a number of different instruments, and will arrive in September 1997, and Mars Pathfinder which consists of a lander and a small rover, landing on Mars July 4, 1997. These are the first two missions of the Mars Exploration Program consisting of a ten year series of small robotic martian probes to be launched every 26 months. The Pathfinder rover will perform a number of technology and operational experiments which will provide the engineering information necessary to design and operate more complex, scientifically oriented surface missions involving roving vehicles and other machinery operating in the martian environment. Because of its expertise in space power systems and technologies, space mechanisms and tribology, Lewis Research Center was asked by the Jet Propulsion Laboratory, which is heading the Mars Pathfinder Program, to contribute three experiments concerning the effects of the martian environment on surface solar power systems and the abrasive qualities of the Mars surface material. In addition, rover static charging was investigated and a static discharge system of several fine Tungsten points was developed and fixed to the rover. These experiments and current findings are described herein.

  8. The construction of meaning by experts and would-be parents in assisted reproductive technology.

    Silva, Susana; Machado, Helena

    2011-09-01

    This article explores the construction of meaning regarding assisted reproductive technology by legal framers, medical practitioners and would-be parents, through the concept of ecology of knowledge. It is argued that these inter-relationships between experts and lay people can be understood in terms of the formation of a social structure of ecology of knowledge, which depends on local and emotional knowledge co-produced by medical doctors, jurists and lay people in dynamic ways without compromising the autonomy of medical, legal and lay knowledge and skills. The assessment of the benefits and risks of assisted reproductive technology partially represents negotiations of knowledge between these social and professional groups, aiming to reproduce existing relations and practices, particularly the social power of medicine and technology, the dominant perceptions about women's and men's bodies and the geneticisation of genealogy. These negotiations of knowledge generate new rights, new social actors, new scientific fields and new ways of thinking and talking about individual and institutional responsibilities. Ecology of knowledge comes imbued with hope, trust, power, credibility of institutions and moralisation whereby some citizens' rights may be weakened.

  9. Fertility tourism: circumventive routes that enable access to reproductive technologies and substances.

    2011-01-01

    “Fertility tourism” is a journalistic eye‐catcher focusing on the phenomenon of patients who search for a reproductive treatment in another country in order to circumvent laws, access restrictions, or waiting lists in their home country. In Europe, the reasons why people seek reproductive treatments outside their national boundaries are quite diverse, in part because regulations differ so much among countries. Beginning with four examples of people who crossed borders for an in vitro fertilization (IVF) treatment with gamete donation, this article provides some insight into these transnational circumvention practices based on material from ethnographic fieldwork and interviews in Spain, Denmark, and the Czech Republic. In all three countries, gamete donation is made strictly anonymous. Clinical practices such as egg donor recruitment and phenotypical matching between donors and recipients serve to naturalize the substitution of gametes and to install social legitimacy through resemblance markers with the prospective child. In comparison to other areas of medical tourism, which are subjects of debate as a consequence of neoliberal health politics and international medical competition, mobility in the area of reproductive technologies is deeply intertwined with new forms of doing kinship. For prospective parents, it holds a promise of generating offspring who could pass as biogenetically conceived children. Therefore, IVF with gamete donation is mostly modeled after conceptions of nature. Through anonymity and concealment it creates forms of nonrelatedness that leave space for future imaginings and traces of transnational genetic creators. PMID:21114072

    The use of Assisted Reproductive Technologies (ARTs) in modern cattle breeding is an important tool for improving the production of dairy and beef cattle. A frequently employed ART in the cattle industry is in vitro production of embryos. However, bovine in vitro produced embryos differ greatly from their in vivo produced counterparts in many facets, including developmental competence. The lower developmental capacity of these embryos could be due to the stress to which the gametes and/or embryos are exposed during in vitro embryo production, specifically ovarian hormonal stimulation, follicular aspiration, oocyte in vitro maturation in hormone supplemented medium, sperm handling, gamete cryopreservation, and culture of embryos. The negative effects of some ARTs on embryo development could, at least partially, be explained by disruption of the physiological epigenetic profile of the gametes and/or embryos. Here, we review the current literature with regard to the putative link between ARTs used in bovine reproduction and epigenetic disorders and changes in the expression profile of embryonic genes. Information on the relationship between reproductive biotechnologies and epigenetic disorders and aberrant gene expression in bovine embryos is limited and novel approaches are needed to explore ways in which ARTs can be improved to avoid epigenetic disorders.

    Many factors negatively affect pregnancy establishment and subsequent fetal growth and development, including maternal factors such as nutritional stress, age, body mass index, and genetic background, and external factors including environmental stress, psychosocial stress, multiple fetuses, medical conditions (e.g., polycystic ovary syndrome), lifestyle choices (e.g., alcohol consumption, smoking), and assisted reproductive technologies. These same factors have similar consequences for placental growth and development, including vascular development. We and others have shown that placental vascular development begins very early in pregnancy and determines, to a large extent, placental function-that is, the magnitude of the increase in placental blood flow and thus nutrient transport to the fetus. During the peri-implantation period and also later in pregnancy, cloned (somatic cell nuclear transfer) embryos exhibit a variety of placental defects including reduced vascularization and altered expression of angiogenic factors. Although placental defects are less pronounced in pregnancies resulting from the transfer of in vitro fertilized embryos, we and others have recently demonstrated that vascularization, expression of angiogenic factors, sex steroid receptors, several epigenetic markers, and growth of utero-placental tissues all were altered during early pregnancy after transfer of embryos obtained through natural mating, in vitro fertilization, or other assisted reproductive techniques. These observations are in agreement with the recent reports that in humans even singleton pregnancies established with assisted reproductive techniques are at increased risk of preterm delivery and low birth weight, and seem especially relevant considering the rapidly expanding use of these techniques in humans and animals.

    This paper describes how grid technology can support the ability of NASA data centers to provide customized data products. A combination of grid technology and commodity processors are proposed to provide the bandwidth necessary to perform customized processing of data, with customized data subsetting providing the initial example. This customized subsetting engine can be used to support a new type of subsetting, called phenomena-based subsetting, where data is subsetted based on its association with some phenomena, such as mesoscale convective systems or hurricanes. This concept is expanded to allow the phenomena to be detected in one type of data, with the subsetting requirements transmitted to the subsetting engine to subset a different type of data. The subsetting requirements are generated by a data mining system and transmitted to the subsetter in the form of an XML feature index that describes the spatial and temporal extent of the phenomena. For this work, a grid-based mining system called the Grid Miner is used to identify the phenomena and generate the feature index. This paper discusses the value of grid technology in facilitating the development of a high performance customized product processing and the coupling of a grid mining system to support phenomena-based subsetting.

    The NASA Glenn Research Center has been developing advanced energy-conversion technologies for use with both radioisotope power systems and fission surface power systems for many decades. Under NASA's Science Mission Directorate, Planetary Science Theme, Technology Program, Glenn is developing the next generation of advanced Stirling convertors (ASCs) for use in the Department of Energy/Lockheed Martin Advanced Stirling Radioisotope Generator (ASRG). The next-generation power-conversion technologies require high efficiency and high specific power (watts electric per kilogram) to meet future mission requirements to use less of the Department of Energy's plutonium-fueled general-purpose heat source modules and reduce system mass. Important goals include long-life (greater than 14-yr) reliability and scalability so that these systems can be considered for a variety of future applications and missions including outer-planet missions and continual operation on the surface of Mars. This paper provides an update of the history and status of the ASC being developed for Glenn by Sunpower Inc. of Athens, Ohio.

    With the development of assisted reproductive technology (ART), more and more hepatitis B virus (HBV)-infected couples have their own children successfully; however,vertical transmission of HBV in ART, especially father-to-child transmission, cannot be avoided. The mechanism of attachment and penetration of HBV into human sperm is still not known. Therefore, understanding the state and mechanism of HBV infection of sperm and the impact of HBV on sperm parameters, following up the ART outcome in man with HBV infection are helpful to solve the fertility problem and to control father-to-child vertical HBV infection.

    In recent years, the US defense industrial base spawned the aerospace industry, among other successes, and served as the nation`s technology seed bed. However, as the defense industrial base shrinks and public and private resources become scarcer, the merging of the commercial and defense communities becomes necessary to maintain national technological competencies. Cooperative efforts such as technology transfer provide an attractive, cost-effective, well-leveraged alternative to independently funded research and development (R and D). The sharing of knowledge, resources, and innovation among defense contractors and other public sector firms, academia, and other organizations has become exceedingly attractive. Recent legislation involving technology transfer provides for the sharing of federal laboratory resources with the private sector. The Army Research, Development and Engineering Center (ARDEC), Picatinny Arsenal, NJ, a designer of weapons systems, is one of the nation`s major laboratories with this requirement. To achieve its important technology transfer mission, ARDEC reviewed its capabilities, resources, intellectual property, and products with commercial potential. The purpose of the review was to develop a viable plan for effecting a technology transfer cultural change within the ARDEC, Picatinny Arsenal and with the private sector. This report highlights the issues identified, discussed, and resolved prior to the transformation of a temporarily vacant federal building on the Picatinny installation into a business incubator. ARDEC`s discussions and rationale for the decisions and actions that led to the implementation of the Picatinny Technology Transfer Innovation Center are discussed.

    1997-09-04

    Operations and maintenance continued this month at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC). Testing for the month involved continued investigations into the Clear Liquor Scrubbing Process for the production of Anhydrous Calcium Sulfate (Anhydrite). The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit and the Carbon Injection System (the Pulse-jet Fabric Filter) remained idle this month in a cold-standby mode and were inspected regularly. From May 3-18, the NYSEG Kintigh Station and the ECTC were off-line for a two-week scheduled Station outage. During the ECTC outage, the major systems of the Center were inspected, and several preventive maintenance activities were completed. A listing of the major O&M outage activities completed during this period is presented in the Pilot/Mini-Pilot section of this report. In May 1997, an extension to the Anhydrite Production test block was started following the NYSEG outage. The extension to the Anhydrite Production test block is being funded by the Electric Power Research Institute (EPRI) after promising results from the original test program. Both EPRI and the Department of Energy (DOE) funded the original test program as part of the DOE`s Advanced Power Systems Program, whose mission is to accelerate the commercialization of affordable, high- efficiency, low-emission, coal-fueled electric generating technologies. While the pilot portion of the Anhydrite project was conducted on the 4.0 MW wet FGD pilot unit at EPRI`s Environmental Control Technology Center (ECTC) in Barker, New York, the extension mainly used the 0.4 MW Mini-Pilot wet FGD unit to reduce operating costs. The project is designed to develop an advanced FGD process that produces a useable byproduct, anhydrite (anhydrous calcium sulfate). The original CLS/Anhydrite process included three steps: chloride removal, clear liquor scrubbing, and anhydrite production. The final step in the process involved

    2015-09-01

    The rise of the Internet Age has brought a host of sweeping changes to the landscape of third-party reproduction. What began as a dyadic relationship between doctor and patient has evolved into a more complex system in which patients are able to access information online from a variety of external sources. Patients often seek to play a more active role in their third-party reproductive care, and the Internet allows them to do so. Further, demand for both medical and psychosocial information about donors and donor-conceived siblings, available online through patient forums and genetic registries, has altered the perception of gamete donation from a one-time event to an ongoing relationship. The advantages and disadvantages for patients and providers of this freer flow of information between third-party participants are examined. Search motivations of recipients and offspring, as well as types of information sought, are detailed. Recommendations are made regarding strategies fertility programs can use to optimally support their patients and navigate this new landscape. PMID:26070518

    Transrectal ultrasonography, electroejaculation and cryopreservation of spermatozoa were applied to the African wild dog (Lycaon pictus) to establish non-invasive protocols for assessing the reproductive health of one of the most endangered African canids. Transrectal ultrasonography was performed on immobilized male (n = 2) and female (n = 5) captive wild dogs. The testes and epididymides of the male dogs were imaged transcutaneously, followed by electrostimulation and cryopreservation of spermatozoa. The sonomorphology of the female and male urogenital tracts was characterized. In females, the vagina, cervix, non-pregnant uterus and ovary were imaged and the reproductive health of each female was evaluated. The sonographic assessment helped to identify one pyometra and extensive abdominal fat deposits in two other individuals in which pyometra had been suspected. Images of the adrenal glands showed differences in size among individuals of the same breeding group. Whether these differences were related to the dominance hierarchy remains to be determined. In males, visualization of the prostate gland, testis and epididymis indicated sexual maturity. Three ejaculatory fractions (1.0, 1.5 and 0.5 ml, with 50, 95 and 95% motility, respectively; 1.125 x 10(8) spermatozoa per ejaculate) were collected from one male. The motility of each of these fractions after thawing was 0, 30 and 40%, respectively. Electrostimulation of the second male, in which a cystic structure in a testis had been identified by sonography, resulted in an aspermic ejaculate (0.5 and 1.0 ml). These technologies provided basic data on reproduction in female and male African wild dogs and were an efficient way to evaluate reproductive health.

Owing to the magnitude of the problem, they have implications not only at the individual and family levels but also at the community level. This leads to an increasing demand for access to assisted reproduction technology (ART) and genetic services, especially when the cause of infertility may be genetic in origin. The increasing application of genetics in reproductive medicine and vice versa requires closer collaboration between the two disciplines. ART and genetics are rapidly evolving fields where new technologies are currently introduced without sufficient knowledge of their potential long-term effects. As for any medical procedures, there are possible unexpected effects which need to be envisaged to make sure that the balance between benefits and risks is clearly on the benefit side. The development of ART and genetics as scientific activities is creating an opportunity to understand the early stages of human development, which is leading to new and challenging findings/knowledge. However, there are opinions against investigating the early stages of development in humans who deserve respect and attention. For all these reasons, these two societies, European Society of Human Genetics (ESHG) and European Society of Human Reproduction and Embryology (ESHRE), have joined efforts to explore the issues at stake and to set up recommendations to maximize the benefit for the couples in need and for the community.

    A resounding success of the Scientific Discover through Advanced Computing (SciDAC) program is that high-performance computational science is now universally recognized as a critical aspect of scientific discovery [71], complementing both theoretical and experimental research. As scientific communities prepare to exploit unprecedened computing capabilities of emerging leadership-class machines for multi-model simulations at the extreme scale [72], it is more important than ever to address the technical and social challenges of geographically distributed teams that combine expertise in domain science, applied mathematics, and computer science to build robust and flexible codes that can incorporate changes over time. The Center for Technology for Advanced Scientific Component Software (TASCS) tackles these issues by exploiting component-based software development to facilitate collaborative hig-performance scientific computing.

The purpose of the OCS is to measure in a quantitative and objective way the notion of culture;'' that is, the values, attitudes, and beliefs of the individuals working within the organization. In addition, through the OCS, a broad sample of individuals can be reached that would probably not be interviewed or observed during the course of a typical assessment. The OCA also provides a descriptive profile of the organization at one point in time that can then be compared to a profile taken at a different point in time to assess changes in the culture of the organization. 9 refs., 33 figs., 6 tabs.

    Assisted reproduction technology laboratories have a very high degree of complexity. Mismatches of gametes or embryos can occur, with catastrophic consequences for patients. To minimize the risk of error, a multi-institutional working group applied failure mode and effects analysis (FMEA) to each critical activity/step as a method of risk assessment. This analysis led to the identification of the potential failure modes, together with their causes and effects, using the risk priority number (RPN) scoring system. In total, 11 individual steps and 68 different potential failure modes were identified. The highest ranked failure modes, with an RPN score of 25, encompassed 17 failures and pertained to "patient mismatch" and "biological sample mismatch". The maximum reduction in risk, with RPN reduced from 25 to 5, was mostly related to the introduction of witnessing. The critical failure modes in sample processing were improved by 50% in the RPN by focusing on staff training. Three indicators of FMEA success, based on technical skill, competence and traceability, have been evaluated after FMEA implementation. Witnessing by a second human operator should be introduced in the laboratory to avoid sample mix-ups. These findings confirm that FMEA can effectively reduce errors in assisted reproduction technology laboratories.

    Midlife, once a focus of particular interest to gerontologists because of its implications for later life, has recently received little attention. But as new reproductive technologies have expanded in the United States, motherhood is occurring at older ages. While older motherhood is not a new social practice, what is unique is that an increasing number of women are becoming pregnant through technological means, often for the first time, at the end of their reproductive cycle. These women can be understood as part of a new middle age, engaging in new life course possibilities that respond to changing social, cultural, physical, and economic realities, and potentially extending much later in the life course. Drawing on interviews with 79 couples, we utilize symbolic interactionist conceptualizations of identity and stigma to consider how women negotiate the shifting social identities associated with older motherhood. We conclude that older motherhood will be one phenomenon contributing to an enduring change in views of what constitutes old age, and that it will be seen as occurring much later in the life course.

  19. Long-term outcomes in children conceived with assisted reproductive technologies.

    2014-10-01

    Over five million children have been born worldwide through assisted reproductive technology (ART) and access to ART treatment is increasing yearly. Investigations of the health, disease, cognitive, developmental and behavioral outcomes in the children conceived with ART are often confounded by parental and other social, environmental and medical factors, including multiplicity, prematurity and low birth weight. Reports of the long-term health and psychosocial adjustment of children conceived with ART show generally good outcomes. Many of the major long-term conditions observed in the children may be associated with multiple gestations, preterm delivery and low birth weight, or with subfertility of the parents. Evidence in the male infants conceived with the aid of intracytoplasmic injection (ICSI) suggests an increased risk of reproductive tract anomalies such as hypospadias. Health-related outcomes of children born after cryopreservation of cleavage stage embryos are reassuring. Currently, our knowledge and understanding of the long-term health risks and/or benefits to the children conceived is incomplete. Measuring long-term outcomes is the first step to improving and optimizing health in the offspring conceived with medical and technological assistance. PMID:25245993

Testing for the Hazardous Air Pollutant (HAP) test block was conducted using the Carbon Injection System (the 4.0 MW Spray Dryer Absorber and the Pulse-jet Fabric Filter). Testing also continued across the B&W/CHX Heat Exchanger this month as the effects of increased particulate loading are being studied. The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit and the 4.0 MW Pilot Wet Scrubber remained idle this month in a cold-standby mode and were inspected regularly. Testing in October at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC) included tests from the Pilot Trace Elements Removal (TER) test block as part of EPRI`s overall program to develop control technology options for reduction of trace element emissions. This experimental program investigates mercury removal and mercury speciation under different operating conditions. The 1996 program is being performed on the 4.0 MW wet FGD pilot unit and the spray dryer/pulse jet fabric filter (SDA/PJFF) pilot units. The 1996 Trace Elements Removal (TER) test block is a continuation of the 1995 TER test block and will focus on up to five research areas, depending on experimental results. These areas are: (1) Mercury speciation methods; (2) Effect of FGD system operating variables on mercury removal; (3) Novel methods for elemental mercury control; (4) Catalytic methods for converting elemental mercury to oxidized mercury; and (5) Electrostatic charging of particulate material in the FGD inlet flue gas stream. The work during October continued to focus on catalytic oxidation of elemental mercury. These tests included the evaluation of two different loadings of catalyst CT-9 (carbon-based material) over extended periods (8-10 days) and an evaluation of FAB-2B (bulk bituminous fly ash taken from the first hopper of the

The Phase I DOE/PRDA testing of the B&W/Condensing Heat Exchanger (CHE) also continued this month as the inlet particulate control system (installed September 1996) is maintaining the inlet particulate mass loading to the unit at an average value of 0.2 lb./MMBTU. The one-year tube wear analysis project conducted across this unit will be completed in the early part of March. At the completion of testing, a final inspection will be conducted before the unit is cleaned, disassembled, and returned to B&W and CH Corp. for additional analysis. Once the unit is removed from the ECTC, the 0.4 MW Mini-Pilot Wet Scrubber unit will be assembled and configured back into the flue gas path for future testing. The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit and the Carbon Injection System (the Pulse-jet Fabric Filter configuration) remained idle this month in a cold-standby mode and were inspected regularly. In February 1997, the Clear Liquor Scrubbing with Anhydrite Production test block continued.

Also, the test plan for July (Dry Sorbent Injection with the Carbon Injection System) was developed and reconfiguration activities were initiated. The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit and the 0.4 MW Mini-Pilot Wet Scrubber remained idle this month in a cold-standby mode and were inspected regularly. These units remain available for testing as future project work is identified. In June 1997, the extension to the Anhydrite Production test block was completed. The extended Anhydrite test block was funded by the Electric Power Research Institute (EPRI) after reviewing the promising results from the original test program. Both EPRI and the Department of Energy (DOE) funded the original PRDA test program as part of the DOE`s Advanced Power Systems Program, whose mission is to accelerate the commercialization of affordable, high-efficiency, low-emission, coal-fueled electric generating technologies. The project is designed to develop an advanced FGD process that produces a usable byproduct, anhydrite (anhydrous calcium sulfate). While the pilot portion of the Anhydrite PRDA project was conducted on the 4-MW wet FGD pilot unit at EPRI`s Environmental Control Technology Center (ECTC) in Barker, New York, the extension testing mainly used the 0.4 MW wet FGD pilot unit to reduce operating costs. As discussed in previous progress reports, the original CLS/Anhydrite process included three steps: chloride removal, clear liquor scrubbing, and anhydrite production. The final step in the process involved sending the calcium sulfite slurry from the sludge bed reactor to the anhydrite reaction tank for conversion to anhydrous calcium sulfate (anhydrite).

    INTRODUCTION Deleterious mutations in the BRCA1/BRCA2 genes elevate lifetime risk of breast and ovarian cancer. Each child of a mutation-positive parent has a 50% chance of inheriting it. Pre-implantation genetic diagnosis (PGD) permits prospective parents to avoid transmitting a BRCA1/2 mutation to a child, introducing predictability into a process historically defined by chance. This investigation explored how BRCA1/2 mutation carriers understand genetic inheritance and consider a child’s inheritance of a BRCA1/2 mutation, given the opportunities that exist to pursue PGD. METHOD 39 female and male BRCA1/2 mutation carriers of reproductive age were recruited from urban cancer and reproductive medical centers. Participants completed a standardized educational presentation on PGD and prenatal diagnosis, with pre- and post-test assessments. An interdisciplinary team of qualitative researchers analyzed data using grounded theory techniques. FINDINGS Participants expressed the belief that reproduction yields children with unique genetic strengths and challenges, including the BRCA1/2 mutation, family traits for which predictive tests do not exist, and hypothetical genetic risks. Participants expressed preference for biologically-related children, yet stated their genetically ‘well’ partner’s lineage would be marred through reproductive merger, requiring the well partner to assume the burden of the BRCA1/2 mutation via their children. Participants expressed diverse views of genetically ‘well’ partners’ participation in family planning and risk management decisions. DISCUSSION Pressure to use reprogenetic technology may grow as genetic susceptibility testing becomes more widely available. Work with individuals and couples across the disease spectrum must be attuned to they ways beliefs about genetic inheritance play into reproductive decision making. PMID:22709328

    Certain restrictions on public funding for assisted reproductive technology (ART) are articulated and defended by recourse to a distinction between medical infertility and social infertility. We propose that underlying the prioritization of medical infertility is a vision of medicine whose proper role is to restore but not to improve upon nature. We go on to mark moral responses that speak of investments many continue to make in nature as properly an object of reverence and gratitude and therein (sometimes) a source of moral guidance. We draw on the work of Ludwig Wittgenstein in arguing for the plausibility of an appeal to nature in opposition to the charge that it must contain a logical fallacy. We also invite consideration of the moral plausibility of some appeal to nature. Finally, we examine what follows in the case of ART. Should medicine respect as natural limits that should not be overcome: the need for a man and a woman in reproduction; menopause; and even declining fertility with age? We must first ask ourselves to what degree we should defer to nature in the conduct of medicine, at least in the particular if not the general case. This will involve also asking ourselves what we think is natural and in what instances and spirit might we defy nature. Divergent opinions and policies concerning who should receive ART treatment and public funding are more easily understood in view of the centrality, complexity and fundamental nature of these questions.

    Objective: To investigate the relationship between male’s body mass index (BMI) and the outcome of assisted reproductive technology (ART). In this retrospective study, we analyzed the data from 729 cycles of female patients aged 38 years or less, with normal BMI and who received IVF treatments between January, 2013 and June, 2014. The patients were divided into normal weight (n = 358), overweight (n = 267), and obese (n = 104) groups according to the BMI of their male partners. Embryonic development and pregnancy outcomes in these three groups were compared. Results: With increasing BMI, fertilization rates decreased proportionately (P < 0.05); but embryonic cleavage rates and effective embryo rates were not significantly affected (P > 0.05). There was no significant difference in implantation rates, pregnancy rates, or early miscarriage rates (P > 0.05) among the three groups. Conclusions: High male BMI affects fertilization rate with ART; and we recommend that men of reproductive age adjust their lifestyles accordingly and make efforts to control their weight.

    Africa for the largest part is still regarded as part of the developing world and has a history of political instability, natural disasters, floods and droughts that all had an effect on the development of livestock production systems and the potential application of biotechnologies.

There is therefore pressure to increase sustainable productivity of livestock. Reproductive technologies such as Artificial Insemination in Africa were driven primarily by the need to control or prevent venereal diseases like Trichomoniases and Campylobacter fetus in cattle.

    Certain restrictions on public funding for assisted reproductive technology (ART) are articulated and defended by recourse to a distinction between medical infertility and social infertility. We propose that underlying the prioritization of medical infertility is a vision of medicine whose proper role is to restore but not to improve upon nature. We go on to mark moral responses that speak of investments many continue to make in nature as properly an object of reverence and gratitude and therein (sometimes) a source of moral guidance. We draw on the work of Ludwig Wittgenstein in arguing for the plausibility of an appeal to nature in opposition to the charge that it must contain a logical fallacy. We also invite consideration of the moral plausibility of some appeal to nature. Finally, we examine what follows in the case of ART. Should medicine respect as natural limits that should not be overcome: the need for a man and a woman in reproduction; menopause; and even declining fertility with age? We must first ask ourselves to what degree we should defer to nature in the conduct of medicine, at least in the particular if not the general case. This will involve also asking ourselves what we think is natural and in what instances and spirit might we defy nature. Divergent opinions and policies concerning who should receive ART treatment and public funding are more easily understood in view of the centrality, complexity and fundamental nature of these questions.

    The advent of innovative techniques for addressing infertility has made for exciting times in the arena of andrology. The success of microTESE for retrieving sperm has enabled azoospermic men to have the opportunity to father biological children when it was previously impossible. The ability to offer a variety of assisted reproductive techniques that includes intracytoplasmic sperm injection has opened the door for couples with male factor infertility who were otherwise untreatable. With the multitude of options available to infertile couples, however, comes an unsurprising degree of controversy regarding what treatments should be offered and when. Complicating the picture is the question of if and when varicocele repair should be undertaken, and the financial implications of the treatment decisions that are made. The infertile couple with varicocele warrants careful consideration. The overall efficacy of varicocele repair as well as cost-effectiveness of repair compared to immediate microTESE in azoospermic men and assisted reproductive technology in men with suboptimal semen parameters will be reviewed.

    2014-01-01

    Gonadotropins extracted from the urine of post-menopausal women have traditionally been used to stimulate folliculogenesis in the treatment of infertility and in assisted reproductive technology (ART). Products, such as human menopausal gonadotropin (hMG), consist not only of a mixture of the hormones, follicle-stimulating hormone (FSH), luteinising hormone (LH) and human chorionic gonadotropin (hCG), but also other biologically active contaminants, such as growth factors, binding proteins and prion proteins. The actual amount of molecular LH in hMG preparations varies considerably due to the purification process, thus hCG, mimicking LH action, is added to standardise the product. However, unlike LH, hCG plays a different role during the natural human menstrual cycle. It is secreted by the embryo and placenta, and its main role is to support implantation and pregnancy. More recently, recombinant gonadotropins (r-hFSH and r-hLH) have become available for ART therapies. Recombinant LH contains only LH molecules. In the field of reproduction there has been controversy in recent years over whether r-hLH or hCG should be used for ART. This review examines the existing evidence for molecular and functional differences between LH and hCG and assesses the clinical implications of hCG-supplemented urinary therapy compared with recombinant therapies used for ART.

    The article presents a literature review over the last few years devoted to the health status and development peculiarities of children born using assisted reproductive technologies (ART) procedures. The statistics shows an explosive increase in the frequency of ART application as a fertility treatment method. The presented data analysis reflects the perinatal outcomes after ART in children, the frequency of congenital malformations and genetic diseases in this population, possible long-term malconditions and pathologies in children born using ART. The overwhelming majority of investigators consider the adverse effect of ART on a child's body to be the result of prematurity and multiple pregnancy (transfer multiple embryos followed by partial reduction). It is stated that the widespread introduction of ART may contribute to the vertical transmission of parental infertility factors in the population. The application of ARTprocedures in some cases is associated with controversial ethical and legal issues (surrogacy, oocyte donation). Further improvements in ART procedures (preimplantation training, medical and genetic diagnosis, reducing the frequency of multiple pregnancy) cannot be stated as an alternative to the general medical and social prevention of reproductive disorders in adolescents and youth.

    As seafood consumption shifts from fisheries harvests to artificially propagated aquatic species, the increase of aquaculture activities poses a biological threat to our environment. Selectively bred, non-native and (eventually) genetically engineered farmed fish may escape from aquaculture operations, propagate and/or interbreed with wild stocks and subsequently alter the genetic makeup of populations in the environment. Thus, an effective strategy for bio-containment of farmed fish is critically needed. Farming reproductively sterile fish is the most environmentally sustainable approach to ensure complete bio-containment in large-scale aquaculture operations. Chromosome set manipulations to produce sterile fish, including polyploidy and hybridization, are currently the most common practices in the aquaculture industry. However, they do not always result in 100% sterility of the treated fish. Moreover, triploid fish typically do not perform as well as the non-manipulated diploids under commercial culture conditions. In the last half decade, several genetic engineering methods have been developed to produce sterile fish. In this review, we will address the latest technologies that use transgenic approaches to eliminate germ cells, resulting in the production of sterile fish. These latest advances also led us to the development of egg/embryo immersion methodologies to deliver and screen compounds that can be used to eliminate primordial germ cells and produce sterile fish. This emerging non-transgenic strategy for the production of reproductively sterile fish in aquaculture will also be discussed.

The Survey is being conducted by an interdisciplinary team of environmental specialists, led and managed by the Office of Environment, Safety and Health's Office of Environmental Audit. Individual team specialists are outside experts being supplied by a private contractor. The objective of the Survey is to identify environmental problems and areas of environmental risk associated with PETC. The Survey covers all environmental media and all areas of environmental regulation. It is being performed in accordance with the DOE Environmental Survey Manual. This phase of the Survey involves the review of existing site environmental data, observations of the operations carried on at PETC, and interviews with site personnel. The Survey team developed a Sampling and Analysis (S A) Plan to assist in further assessing certain environmental problems identified during its on-site Survey activities at PETC. The S A Plan will be executed by the Oak Ridge National Laboratory (ORNL). When completed, the Plan's results will be incorporated into the PETC Survey findings for inclusion into the Environmental Survey Summary Report. 64 refs., 23 figs., 29 tabs.

    Operations and maintenance continued this month at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC). Testing for the month involved the EPRI Integrated SO{sub x}/NO{sub x} removal process, the DOE PRDA testing of the B&W/Condensing Heat Exchanger (CHX), and support for the Semi-Continuous On-line Mercury Analyzer. The test configuration utilized in the EPRI Integrated SO{sub x}/NO{sub x} removal process included the 4.0 MW Spray Dryer Absorber (SDA), the Pulse-jet Fabric Filter (PJFF), and a new Selective Catalytic Reduction (SCR) reactor installed at the ECTC. During this testing, O&M support was also required to conclude the test efforts under the EPRI Hazardous Air Pollutant (HAP) test block. This included the on-site development efforts for the Semi-Continuous On-line Mercury Analyzer. In the DOE PRDA project with the B&W/Condensing Heat Exchanger (CHX), the effects of the increased particulate loading to the unit were monitored throughout the month. Also, the 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit and the 4.0 MW Pilot Wet Scrubber remained idle this month in a cold-standby mode and were inspected regularly.

    Utility-scale wind turbines operate in dynamic flows that can vary significantly over timescales from less than a second to several years. To better understand the inflow to utility-scale turbines, two inflow towers were installed and commissioned at the National Renewable Energy Laboratory's (NREL) National Wind Technology Center near Boulder, Colorado, in 2011. These towers are 135 m tall and instrumented with a combination of sonic anemometers, cup anemometers, wind vanes, and temperature measurements to characterize the inflow wind speed and direction, turbulence, stability and thermal stratification to two utility-scale turbines. Herein, we present variations in mean and turbulent wind parameters with height, atmospheric stability, and as a function of wind direction that could be important for turbine operation as well as persistence of turbine wakes. Wind speed, turbulence intensity, and dissipation are all factors that affect turbine performance. Our results shown that these all vary with height across the rotor disk, demonstrating the importance of measuring atmospheric conditions that influence wind turbine performance at multiple heights in the rotor disk, rather than relying on extrapolation from lower levels.

    As a number of children born by assisted reproductive technology (ART) are increasing each year across the developed world, the health of such offspring is a matter of public concern. Does the integrity of the paternal genome impact on offspring health? In societal terms, as birth rates fall, and the Western population become unsustainable, do the benefits outweigh the costs of creating and providing for this ART conceived subpopulation? There are little data to date to answer these questions. The long-term health of such children has largely been ignored, and success measured only by early (prebirth) outcomes such as embryo quality or pregnancy. However, there are powerful paradigms such as ageing and smoking that give vital clues as to the potential impact of unhealthy spermatozoa on disease risk, mental and physical health, fertility and mortality of these offspring.

    Fertility in cattle is a major component of many agricultural enterprises and there is pressure to devise methods to improve this. A number of approaches are ongoing, one of which is to better understand the cellular and molecular events of the development of reproductive tissues and to use these as targets for developing new strategies. Microarray technologies now allow us the potential to determine the transcriptional profile of expressed genes in a given tissue. This review focuses on the types of microarrays available for studies in cattle and concludes that genes associated with one or more of the cellular processes of cell survival/death, intracellular signalling, transcription and translation, cell division and proliferation and cellular metabolism are the main transcriptional pathways that control the development of ovarian follicles, oocytes, early embryos and the uterine endometrium about the time of the establishment of pregnancy.

    Children conceived via assisted reproductive technologies (ART) are nowadays a substantial proportion of the population. It is important to follow up these children and evaluate whether they have elevated health risks compared to naturally conceived (NC) children. In recent years there has been a lot of work in this field. This review will summarize what is known about the health of ART-conceived children, encompassing neonatal outcomes, birth defects, growth and gonadal developments, physical health, neurological and neurodevelopmental outcomes, psychosocial developments, risk for cancer, and epigenetic abnormalities. Most of the children conceived after ART are normal. However, there is increasing evidence that ART-conceived children are at higher risk of poor perinatal outcome, birth defects, and epigenetic disorders, and the mechanism(s) leading to these changes have not been elucidated. Continuous follow-up of children after ART is of great importance as they progress through adolescence into adulthood, and new ART techniques are constantly being introduced. PMID:23645173

    Listening to other cultures offers challenges to our fundamental assumptions and worldviews. In New Zealand public policy on Assisted Reproductive Technology (ART) is being worked out in a society committed to the development of bicultural partnership honouring the Treaty of Waitangi, a treaty with the indigenous people. Strong claims to the cultural significance of genetic heritage by Maori have made apparent to non-Maori (Pakeha) their own assumptions. These claims also resist reductive understandings of genetics. In this paper I review, as a Pakeha ethicist, initiatives taken in New Zealand, and the impact of bicultural development on public policy on ART. I also discuss some of the issues this raises for western bioethics as it relates to non-western approaches and include reference to the significance of genetic heritage as it is affecting guidelines for donor insemination and surrogacy.

    We compared the symptoms of 91 Taiwanese women, 50 pregnant by assisted reproductive technology (ART), with those of 41 women, pregnant without assistance. They completed a self-administered demographic questionnaire and symptomatology inventory (SI) during each trimester. The ART group had a higher frequency of complications and hospitalizations than the unassisted women. No significant differences were found in physical and affective symptoms in the ART group across three trimesters, but significant differences were found in the unassisted group. In addition, ART and non-ART women differed in types of individual symptoms experienced each trimester. These findings suggest the need for nurses to assess each group for the presence of specific symptoms throughout pregnancy and to provide individualized symptom management.

    Infertility is a common yet complex problem affecting approximately 10-15% of couples attempting to conceive a baby. Especially, 40-50% of these factors are known as male-related disorders. Unlike female infertility, the cause of which is often easily identified, diagnosing male factors can be difficult. Male infertility is due to low sperm production, abnormal sperm function or blockages of sperm transport. Classical semen analysis in laboratory, which include sperm concentration, motility and morphology gives an approximate evaluation of the functional competence of spermatozoa, but does not always reflect the quality of sperm DNA. The fertilizing potential of sperm depends not only on the functional competence of spermatozoa but also on sperm DNA integrity. The most commonly used techniques to assess sperm DNA integrity are the TUNEL assay, Comet assay, SCSA assay and hallo sperm assay. Recent studies have highlighted the significance of sperm DNA integrity as an important factor which affects functional competence of the sperm. Sperm DNA damage has been closely associated with numerous indicators of reproductive health including fertilization, embryo quality, implantation, spontaneous abortion, congenital malformations. To overcome male infertility, there are variety of surgical and non-surgical urological procedures and medical-pharmacological interventions, and advanced assisted reproductive technologies (ART). Among the surgically retrieved methods, there are TESE, TFNA, PESA and MESA that is used with ICSI. The ART, augmented with ICSI in moderate to serve cases, efficiently treat a variety of male infertility disorders by constituting validated and successfully treatment methods. Also, this technique is employed because the limited numbers and functional capacity of motile sperm that can be obtained. Especially, there are technologies such as IMSI and PICSI that are used to select healthy sperms.

    An Organizational Cultural Assessment (OCA) was performed at the Energy Technology Engineering Center (ETEC) by administering an Organizational Culture Survey (OCS) that queried employees on the subjects of organizational culture, various species of communication, employee commitment to ETEC, work group cohesion, coordination of work, environmental, safety and health concerns, hazardous nature of work, and overall job satisfaction. A description of each of the scales used to assess these subjects is discussed. The primary purpose of administering the survey was to attempt to measure, in a more quantitative and objective way the notion of organizational culture, '' that is, the values, attitudes, and beliefs of the individuals working within the organization. In particular, those aspects of the working environment which are believed to be important influences on the operations of a facility and on the safety issues relevant to the organization were assessed. In addition, by conducting a survey, a broad sampling of the individuals in the organization can be obtained. This is especially important when the survey is utilized in conjunction with an assessment or inspection team which typically has only a limited amount of resources to address many issues. The OCS provides a broad, but more comprehensive picture of the organization by querying a much larger number of individuals than could be reached through the assessment team alone. Finally, the OCS provides a descriptive profile of the organization at one point in time. This profile can then can be used as a baseline point against which comparisons of other points in time can be made. Such comparisons may prove valuable and would help to assess changes in the organizational culture. Comparisons of the profiles can also be made across similar facilities. 9 refs., 22 figs., 6 tabs.

  19. Incidence of abnormal offspring from cloning and other assisted reproductive technologies.

    PubMed

    Hill, Jonathan R

    2014-02-01

    In animals produced by assisted reproductive technologies, two abnormal phenotypes have been characterized. Large offspring syndrome (LOS) occurs in offspring derived from in vitro cultured embryos, and the abnormal clone phenotype includes placental and fetal changes. LOS is readily apparent in ruminants, where a large calf or lamb derived from in vitro embryo production or cloning may weigh up to twice the expected body weight. The incidence of LOS varies widely between species. When similar embryo culture conditions are applied to nonruminant species, LOS either is not as dramatic or may even be unapparent. Coculture with serum and somatic cells was identified in the 1990s as a risk factor for abnormal development of ruminant pregnancies. Animals cloned from somatic cells may display a combination of fetal and placental abnormalities that are manifested at different stages of pregnancy and postnatally. In highly interventional technologies, such as nuclear transfer (cloning), the incidence of abnormal offspring continues to be a limiting factor to broader application of the technique. This review details the breadth of phenotypes found in nonviable pregnancies, together with the phenotypes of animals that survive the transition to extrauterine life. The focus is on animals produced using in vitro embryo culture and nuclear transfer in comparison to naturally occurring phenotypes.

It also speaks to the meanings of and approaches which may be used to study biopolitics. Biopolicy is the approach used in the course. The second part addresses the problem of finding a unifying concept which would bring cohesion to the multiple and diverse materials and issues. It also includes the statement of purpose and course objectives. It is here that the development of identifying and demonstrating the nexus between the reproductive technologies and public policy begins. It also discusses methodologies used in the course. The third part lists the activities that served as a guide in designing the course and cites remaining caveats in course development. The paper concludes with statements about required reading materials, review materials, audio-visual aids, and a broad outline of the course. PMID:17153268

    OBJECTIVES The main objective of the report is to review the evidence on the impact of health information technology (IT) that supports patient-centered care (PCC) on: health care processes; clinical outcomes; intermediate outcomes (patient or provider satisfaction, health knowledge and behavior, and cost); responsiveness to needs and preferences of patients; shared decisionmaking and patient-clinician communication; and access to information. Additional objectives were to identify barriers and facilitators for using health IT to deliver PCC, and to identify gaps in evidence and information needed by patients, providers, payers, and policymakers. DATA SOURCES MEDLINE®, Embase®, Cochrane Library, Scopus, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, INSPEC, and Compendex databases through July 31, 2010. METHODS Paired members of our team reviewed citations to identify randomized controlled trials of PCC-related health IT interventions and studies that addressed barriers and facilitators for health IT for delivery of PCC. Independent assessors rated studies for quality. Paired reviewers abstracted data. RESULTS The search identified 327 eligible articles, including 184 articles on the impact of health IT applications implemented to support PCC and 206 articles addressing barriers or facilitators for such health IT applications. Sixty-three articles addressed both questions. The study results suggested positive effects of PCC-related health IT interventions on health care process outcomes, disease-specific clinical outcomes (for diabetes mellitus, heart disease, cancer, and other health conditions), intermediate outcomes, responsiveness to the needs and preferences of patients, shared decisionmaking, patient-clinician communication, and access to medical information. Studies reported a number of barriers and facilitators for using health IT applications to enable PCC. Barriers included: lack of usability; problems with access to the health IT

    Background Teens and young adults in the United States are in need of sexual and reproductive health information, as evidenced by elevated rates of sexually transmitted infections (STIs), pregnancy, and births among this population. In-person sexuality education programs are helpful, but they are unlikely to rapidly accommodate teens and young adults in a moment of crisis. Evidence suggests that technologies such as instant messaging (IM) and text messaging may be effective ways to provide teens and young adults with sexual and reproductive health information. In September 2010, Planned Parenthood Federation of America launched a text and IM program designed to provide immediate answers to urgent sexual and reproductive health questions from a reliable and confidential source and to link young people to sexual and reproductive health services if needed. Objective To assess whether this program is successful in reaching the target population, whether user characteristics vary by mode (IM vs text), and whether mode is associated with reaching individuals with high levels of worry or reducing worry postchat. Methods Data were collected from prechat and postchat surveys for all IM and text message conversations between September 2010 and August 2011. A bivariate analysis was conducted using chi-square tests for differences in the main covariates by mode of conversation. In the multivariable analysis, logistic regression was used to identify factors that were independently associated with prechat levels of worry and changes in worry postchat. Results A total of 32,589 conversations occurred during the program’s first year. The odds of feeling very worried prechat were highest for IM users (adjusted odds ratio [AOR] 1.43, 95% CI 1.20-1.72), users 17 years and younger (AOR 1.62, 95% CI 1.50-1.74), Latino/Hispanic users (AOR 1.36, 95% CI 1.27-1.46), and black users (AOR 1.40, 95% CI 1.30-1.50). After controlling for the study covariates, there was no significant

    This report summarizes the technical and educational achievements of the Graduate Automotive Technology Education (GATE) Center at West Virginia University (WVU), which was created to emphasize Advanced Hybrid Vehicle Technology. The Center has supported the graduate studies of 17 students in the Department of Mechanical and Aerospace Engineering and the Lane Department of Computer Science and Electrical Engineering. These students have addressed topics such as hybrid modeling, construction of a hybrid sport utility vehicle (in conjunction with the FutureTruck program), a MEMS-based sensor, on-board data acquisition for hybrid design optimization, linear engine design and engine emissions. Courses have been developed in Hybrid Vehicle Design, Mobile Source Powerplants, Advanced Vehicle Propulsion, Power Electronics for Automotive Applications and Sensors for Automotive Applications, and have been responsible for 396 hours of graduate student coursework. The GATE program also enhanced the WVU participation in the U.S. Department of Energy Student Design Competitions, in particular FutureTruck and Challenge X. The GATE support for hybrid vehicle technology enhanced understanding of hybrid vehicle design and testing at WVU and encouraged the development of a research agenda in heavy-duty hybrid vehicles. As a result, WVU has now completed three programs in hybrid transit bus emissions characterization, and WVU faculty are leading the Transportation Research Board effort to define life cycle costs for hybrid transit buses. Research and enrollment records show that approximately 100 graduate students have benefited substantially from the hybrid vehicle GATE program at WVU.

    In France as in other countries, more and more single women and lesbian couples wish to become mothers. To carry through their parenting project they may consult a physician in France and often go abroad in order to get Assisted Reproductive Technologies with donor sperm (ARTD). Should ARTD be available to those women in France? The physician has not to take the decision. In such situations ARTD has no medical indication or contraindication. This assisted procreation raises many questions on children development and well-being. The results of studies made in other countries are often reassuring but their methodologies do not allow any conclusion to be drawn and grey areas persist. Therefore it should be necessary to develop a research effort in the field as it recently started in France. Would ARTD access to women without a male partner be legalized, the law should respect the ethical principles of non-payment and anonymity associated with donation of all body components. In any case, it should also allow an efficient medical care to be performed to ensure under the best conditions the well-being of the children and their mothers. PMID:26753417

    The aim of this review was to examine studies describing the psychological stress and adjustment in pregnancy after an assisted reproductive technology (ART) treatment. A systematic search of the electronic databases was performed. This review considered only quantitative, primary studies in the English language, published during the period 2000-2014 and relevant to the objective. The population of interest was previously infertile pregnant women. Outcome variables were general anxiety, depressive symptoms, pregnancy-specific anxiety, quality of life, self-esteem, pregnancy attitudes and adjustment, and maternal-fetal attachment. Twenty studies met the inclusion and methodological criteria and were included in the review. The review revealed that compared to women who conceive naturally or to general norms, women who conceive after an in vitro fertilization treatment had greater pregnancy-specific anxiety, poorer quality of life, either the same or less depressive symptomatology, the same level of self-esteem, more positive attitudes toward pregnancy demands, and higher levels of maternal-fetal attachment. However, the evidence regarding the general anxiety levels in pregnancy after an ART treatment was inconclusive. Methodological limitations and differences across studies may explain the inconsistencies in their findings regarding the impact of ART. This review provides an insight into psychological reactions and adjustment in pregnancy after an ART treatment.

    Intake of full-fat dairy has been linked to lower semen quality but whether this leads to decreased fertility is unknown. To address this question, we prospectively evaluated the association of men's dairy intake with treatment outcomes of subfertile couples undergoing assisted reproductive technology (ART). We followed 142 men from couples undergoing infertility treatment with ART at an academic fertility centre between 2007 and 2014. Couples completed dietary assessments prior to treatment, and the female partners underwent a total of 248 ART cycles. Multivariable generalized linear mixed models were used to examine the association of dairy intake with fertilization, implantation, clinical pregnancy and live birth rates adjusting for age, body mass index, smoking status, total exercise time, dietary patterns, alcohol, caffeine, total energy intake, and female dairy intake. Intake of dairy foods, regardless of their fat content, was not associated with fertilization, implantation, clinical pregnancy or live birth rates. The adjusted live birth rates (95% confidence interval) for couples in increasing quartiles of men's dairy intake were 0.42 (0.25, 0.60), 0.25 (0.13, 0.42), 0.26 (0.15, 0.41), and 0.44 (0.27, 0.63) (p linear trend = 0.73). Results remained similar after adjustment for female partner intake of dairy foods. Overall, men's dairy intake was not associated with treatment outcomes of couples undergoing ART.

  9. Corpus luteal contribution to maternal pregnancy physiology and outcomes in assisted reproductive technologies.

    Investigations in the rat model of pregnancy indicate an important role for the corpus luteal (CL) hormone relaxin in the maternal circulatory and osmoregulatory changes in pregnancy, which are epitomized by profound vasodilation and modest hypoosmolality, respectively. In a pilot study of infertile women who became pregnant through donor eggs, in vitro fertilization, and embryo transfer, the gestational rise in glomerular filtration and fall in plasma osmolality were markedly subdued. Because these women were infertile, they lacked a CL and circulating relaxin (and possibly other vasoactive CL hormones). Based on these findings in pregnant rats and women, we hypothesize that infertile women conceiving through donor eggs will have overall subdued circulatory changes (e.g., attenuated reduction in systemic vascular resistance and subdued increase in cardiac output) particularly during early pregnancy when CL hormones predominate before the full development and maturation of the placenta. In contrast, infertile women conceiving by autologous eggs retrieved after ovarian stimulation and fresh embryo transfer may have a relatively hyperdynamic circulation due to the presence of many CL (up to 20 or more) and higher circulating levels of vasodilatory ovarian hormones such as relaxin. Emerging evidence suggests that women undergoing Assisted Reproductive Technologies (ART) have increased risk for adverse pregnancy outcomes such as preeclampsia and small for gestational-age babies. This increased risk may be partly caused by the maternal milieu, which is not physiological in ART pregnancies due to the abnormal status of the CL.

    Epidemiological studies in humans have demonstrated a relationship between pathological events during fetal development and increased cardiovascular risk later in life and have led to the so called "Fetal programming of cardiovascular disease hypothesis". The recent observation of generalised vascular dysfunction in young apparently healthy children conceived by assisted reproductive technologies (ART) provides a novel and potentially very important example of this hypothesis. This review summarises recent data in ART children demonstrating premature subclinical atherosclerosis in the systemic circulation and pulmonary vascular dysfunction predisposing to exaggerated hypoxia-induced pulmonary hypertension. These problems appear to be related to the ART procedure per se. Studies in ART mice demonstrating premature vascular aging and arterial hypertension further demonstrate the potential of ART to increase cardiovascular risk and have allowed to unravel epigenetic alterations of the eNOS gene as an underpinning mechanism. The roughly 25% shortening of the life span in ART mice challenged with a western style high-fat-diet demonstrates the potential importance of these alterations for the long-term outcome. Given the young age of the ART population, data on cardiovascular endpoints will not be available before 20 to 30 years from now. However, already now cohort studies of the ART population are needed to early detect cardiovascular alterations with the aim to prevent or at least optimally treat cardiovascular complications. Finally, a debate needs to be engaged on the future of ART and the consequences of its exponential growth for public health. PMID:24964004

    This study was carried out to explore associations between assisted reproductive technology (ART) and maternal and neonatal outcomes compared with similar outcomes following spontaneously conceived births. We conducted a retrospective cohort study of pregnancies conceived by ART (N = 2641) during 2006–2014 compared to naturally conceived pregnancies (N = 5282) after matching for maternal age and birth year. Pregnancy complications, perinatal complications and neonatal outcomes of enrolled subjects were investigated and analysed by multivariate logistic regression. We found that pregnancies conceived by in vitro fertilization (IVF) were associated with a significantly increased incidence of gestational diabetes mellitus, gestational hypertension, preeclampsia, intrahepatic cholestasis of pregnancy, placenta previa, placental abruption, preterm premature rupture of membranes, placental adherence, postpartum haemorrhage, polyhydramnios, preterm labour, low birth weight, and small-for-date infant compared with spontaneously conceived births. Pregnancies conceived by intracytoplasmic sperm injection (ICSI) showed similar elevated complications, except some of the difference narrowed or disappeared. Singleton pregnancies or nulliparous pregnancies following ART still exhibited increased maternal and neonatal complications. Therefore, we conclude that pregnancies conceived following ART are at increased risks of antenatal complications, perinatal complications and poor neonatal outcomes, which may result from not only a higher incidence of multiple pregnancy, but also the manipulation involved in ART processes.

    The assisted reproductive technologies, particularly in vitro fertilization (IVF), represent the most efficient and successful means of overcoming infertility associated with endometriosis. Although older studies suggest that IVF outcomes are compromised in endometriosis patients, more contemporary reports show no differences compared to controls. The exception may be evidence of poorer outcomes and diminished ovarian response in women with advanced disease, particularly those with significant ovarian involvement or prior ovarian surgery. Prolonged pre-IVF cycle suppressive medical therapy, particularly gonadotropin releasing hormone agonists, appears to improve success rates in a subset of endometriosis patients. However, as of yet, there is no diagnostic marker to specifically identify those who would most benefit from this approach. Pre-IVF cycle surgical resection of nonovarian disease has not been consistently shown to improve outcomes with the possible exception of resection of deeply invasive disease, although the data is limited. Precycle resection of ovarian endometriomas does not have benefit and should only be performed for gynecologic indications. Indeed, there is a large body of evidence to suggest that this procedure may have a deleterious impact on ovarian reserve and response. A dearth of appropriately designed trials makes development of definitive treatment paradigms challenging. PMID:26240824

    The efficiency of assisted reproductive technologies (ARTs) in nonhuman primates is low due to no screening criterions for selecting sperm, oocyte, and embryo as well as its surrogate mothers. Here we analyzed 15 pairs of pregnant and non-pregnant cynomolgus monkeys, each pair of which received embryos from one batch of fertilized oocytes, and found ratio of endometrial to myometrial thicknesses in abdominal ultrasonic transverse section of uterus is a reliable indicator for selection of recipients for embryo transfer. We performed 305 ovarian stimulations in 128 female cynomolgus monkeys and found that ovarian stimulation can be performed in a whole year and repeated up to six times in the same monkey without deteriorating fertilization potential of eggs until a poor response to stimulation happened. Fertilization can be efficiently achieved with both conventional and piezo-driven intracytoplasmic sperm injection procedures. In semen collection, semen quality is higher with the penile robe electrical stimulus method compared with the rectal probe method. Moreover, caesarean section is an effective strategy for increasing baby survival rates of multiple pregnancies. These findings provide a practical guidance for the efficient use of ARTs, facilitating their use in genetic engineering of macaque monkeys for basic and translational neuroscience research.

    Reproductive genetic technologies (RGTs) allow parents to decide whether their future children will have or lack certain genetic predispositions. A popular model that has been proposed for regulating access to RGTs is the ‘genetic supermarket’. In the genetic supermarket, parents are free to make decisions about which genes to select for their children with little state interference. One possible consequence of the genetic supermarket is that collective action problems will arise: if rational individuals use the genetic supermarket in isolation from one another, this may have a negative effect on society as a whole, including future generations. In this article we argue that RGTs targeting height, innate immunity, and certain cognitive traits could lead to collective action problems. We then discuss whether this risk could in principle justify state intervention in the genetic supermarket. We argue that there is a plausible prima facie case for the view that such state intervention would be justified and respond to a number of arguments that might be adduced against that view.

    The chorionicity–based evaluation of the perinatal risk in twin pregnancies after assisted reproductive technology (ART) is lacking. A retrospective review was performed of all twin pregnancies monitored prenatally and delivered at our hospital between 2010 and 2014. Chorionicity was diagnosed by ultrasound examination at first trimester and confirmed by postnatal pathology. Pregnancy and perinatal outcomes were prospectively recorded. Adjusted odds ratios (aOR) with 95% confidence intervals (CI) were calculated in a logistic regression model. A total of 1153 twin pregnancies were analyzed. The occurrence of preterm premature rupture of membranes (PPROM) was 3 times as frequent in monochorionic diamniotic (MCDA) twin pregnancies after ART as in those spontaneous counterparts (aOR 3.0; 95%CI 1.1–3.2). The prevalence of intrahepatic cholestasis of pregnancies (ICP) was significantly higher in dichorionic diamniotic (DCDA) twin pregnancies following ART compared to spontaneous DCDA pregnancies (aOR 3.3; 95%CI 1.3–5.6). Perinatal outcomes did not differ between two conception methods, either in MCDA or DCDA twin pregnancies. Based on differentiation of chorionicity, ART is associated with the increased risk of PPROM in MCDA twin pregnancies and with a higher rate of ICP in DCDA twin gestations. ART does not increase adversity of perinatal outcomes in twin pregnancies. PMID:27243373

    Female infertility rates have increased by approximately 4% since the 1980s. There is evidence of adverse effects on female fertility in relation to exposure of chemical pollution in recent years. Follicular fluid samples were collected from 127 woman patients (aged 20-35) who underwent assisted reproductive technologies (ART) and had no records indicating occupational exposure to OCPs. Seventeen OCPs were analyzed in this study. The results showed that methoxychlor was dominant, accounted for 13.4% of total OCPs with a mean concentration of 167.9 ± 33.9 ng/g lipid weight (lw), followed by heptachlor-epoxide, hexachlorocyclohexanes, endrin and DDT. The concentrations of OCPs in the follicular fluid samples in the present study were moderate in comparison with those reported from developed or industrialized countries. All these pollutants can accumulate in different tissues of human body through diet, drinking water and respiration. No correlation between patient age and OCP concentrations was observed in this study. PMID:26412266

    Artificial insemination and embryo transfer programs are dependent on efficient and accurate detection of estrus. Visual observation is accurate at detecting animals in estrus, but efficiency ranges from approximately 50 to 70%. Electronic technologies have been developed in attempts to improve estrus detection efficiency. Commercially available electronic devices for estrus detection are based on changes in physical activity (pedometers), changes in electrical resistance of reproductive tract secretions (intravaginal resistance probes) or mounting activity (mount detectors). All of the commercially available electronic estrus detection devices can improve the efficiency of estrus detection in cattle. Pedometers are most applicable to lactating dairy cattle and have greater accuracy and efficiency when combined with visual observation. Intravaginal resistance measurement is perhaps the least practical method of estrus detection because of labor and animal handling requirements. Individual resistance measurement may have practical application for confirming other inconclusive signs of estrus. Mount monitors have the broadest application to beef and dairy cattle. HeatWatch, the only real-time radiotelometric system available, requires the least labor and animal handling and provides data on the time and duration of each mount. The less expensive stand-alone mount monitors also provide the necessary information for optimum timing of insemination and embryo transfer, but are more labor intensive. PMID:11775966

    Over the course of the past 35 years, assisted reproductive technologies (ARTs) have been increasingly used worldwide, while debates on their safety have been generated. Birth defects and imprinting disorders were reported in previous research. Thus, the psychological development of children born following ARTs has become a major concern nowadays. This review gives a systematic view of psychological well-being of children conceived by different types of ART, including in vitro fertilization, intracytoplasmic sperm injection (ICSI), preimplantation genetic diagnosis/screening, and in vitro maturation. The previous studies are analyzed in three sections: (1) cognitive, motor, and language developments, (2) behavior problems and socio-emotional development, and (3) parent-child relationship. We conclude that although the majority of the studies on cognitive, motor, and language developments reported comparable achievements in the ART group vs. the naturally conceived group, lower intelligence quotient (IQ) scores, worse visual-motor ability or locomotor development, and delayed receptive language competence were found in the ART group. The results on the socio-emotional development were reassuring. As for the behavior problems, a higher prevalence of behavior problems existed in ART children; moreover, ICSI children were found to be at a higher risk of autism than the general population. Meanwhile, ART parents tended to have positive parental attitudes and be more protective of their children. Some suggestions for further research are also given in this review. PMID:24190441

    2011-11-01

    Unexplained recurrent miscarriage (RM) is a significant health problem for which no effective treatment is available yet. In only 50% of couples with RM a cause can be found. In clinical practice, a frequently asked question is whether assisted reproductive technology (ART) is a treatment option. The scientific rationale and the chances of success for ART in couples with unexplained RM are still controversial. Presently, there is not enough evidence to justify IVF or intrauterine insemination (IUI) as a treatment option. Research on oocyte donation has been reported in one article. It is questionable whether couples with unexplained RM would undergo the potential risks and emotional aspects of ART. There is insufficient data on whether preimplantation genetic diagnosis improves the live birthrate in carriers of a structural chromosome rearrangement with a history of RM. No randomized controlled trials are available for preimplantation genetic screening (PGS) for unexplained RM. A recently published review concluded that the live birthrate for IVF/PGS and natural conception groups appears to be quite similar. Because evidence is lacking, we recommend refraining from ART in couples with recurrent miscarriage. PMID:22161467

    During treatments with assisted reproductive technologies (ART), some men may have difficulties in producing spermatozoa on demand at the time of insemination, either for intrauterine insemination (IUI) or for in-vitro fertilization (IVF). This situation imposes tremendous stress on the couple and may cause cancellation of the treatment. Here we describe, for the first time, the use of sildenafil citrate (ViagraTM) for temporary erectile dysfunction in couples undergoing ART. The first case was a man who could not produce spermatozoa for the first IVF treatment after an exhausting trial for 12 h, despite the fact that he never had problems in providing sperm samples during previous IUI cycles. Using Viagra enabled him to provide spermatozoa, but the delay in oocyte insemination resulted in no embryonic development. This prompted us to be more alert to this option and to suggest the use of Viagra to men who had a history of erectile dysfunction during previous ART cycles. In these cases, the use of Viagra was planned in advance and it successfully solved any unpredictable erectile dysfunction on the day of insemination. Such cases emphasize the need to think in advance of this potential use of Viagra during ART. PMID:10402389

    Although in the UK the upper age limit for National Health Service (NHS) provision of in vitro fertilisation (IVF) is 39 years of age there has been an increase in number of women having fertility treatment in their 40s. However, the success rates of IVF and intra-uterine insemination (IUI) in this group remain low. Human Fertilisation and Embryology Authority (HFEA) data from 2006 showed that the live-birth rate from IVF in the UK was 11% in the age group 40-42, 4.6% in the age group 43-44 and less than 4% in women over 44. We performed a literature search for studies using terms and combinations of terms in online databases and published meta-analyses reporting the outcome of interventions in older women. This review showed that assisted reproduction technologies (ARTs) continue to have low live-birth rates in women over 40. Trials showed that assisted hatching may increase the chance of pregnancy in women with poor history. Blastocyst transfer is associated with better outcome, whereas application of pre-implantation genetic screening (PGS) in older women has not increased the success rates. It appears that, with the exception of egg-donation, ART has no answer yet to age-related decline of female fertility. PMID:21329469

    2013-11-01

    The early embryonic environment has been shown to be remarkably influential on the developing organism, despite the relative brevity of this developmental stage. The cells of the zygote and cleavage-stage embryo hold the potential to form all cell lineages of the embryonic and extra-embryonic tissues, with gradual fate restriction occurring from the time of compaction and blastocyst formation. As such, these cells carry with them the potential to influence the phenotype of all successive cell types as the organism grows, differentiates and ages. The implication is, therefore, that sublethal adverse conditions which alter the developmental trajectory of these cells may have long-term implications for the health and development of the resulting offspring. One confirmed mechanism for the translation of environmental cues to phenotypic outcome is epigenetic modification of the genome to modulate chromatin packaging and gene expression in a cell- and lineage-specific manner. The influence of the periconceptional milieu on the epigenetic profile of the developing embryo has become a popular research focus in the quest to understand the effects of environment, nutrition and assisted reproduction technology on human development and health.

    Background The field of infertility medicine has witnessed a surge of scientific developments in recent years, but research on public attitudes towards infertility treatments has remained minimal. This study examined the social and demographic factors that affect women’s attitudes towards assisted reproductive technology (ART) in general, as well as their opinions of specific issues related to ART. Materials and Methods This cross-sectional study was conducted from March 2011 to April 2011 by means of an online survey administered to a sample of 287 women. Results Women with a longer length of awareness of ART had significantly greater attitudinal favorability towards ART. Political affiliation was also significantly related to general attitudes, as well as several specific aspects of ART issues. Conclusion The results of this study suggest that several factors influence attitudes that women hold in regards to ART. Identifying some of these factors serves as a crucial starting point for devising strategies to increase public acceptance of ART. PMID:27110326

    Purpose Prader-Willi syndrome (PWS) is an imprinting disorder characterized by typical facial, physical and cognitive/behavioral features, resulting from lack of paternally-expressed genes on chromosome 15q11.2-q13. Studies have suggested an increased risk of other imprinting disorders in children conceived by assisted reproductive techniques (ART). This study was designed to determine the association between ART and PWS. Methods Data on individuals with PWS were collected from three distinct sources and the proportion of ART-births analyzed. Results The proportion of ART-births in the Prader-Willi Syndrome Association [PWSA (USA)], Rare Diseases Clinical Research Network (RDCRN), and University of California, Irvine Medical Center (UCIMC) populations was 1.0% (18/1,736), 1.0% (1/98), and 2.0% (1/50), respectively (overall 1.1%; population frequency for the U.S was 1.0%). Interestingly, 2.4% (45/1,898) of participants were co-twins (eleven born after ART procedures); U.S. twin frequency is 1.6% (p=0.007). The proportion of individuals with maternal disomy 15/imprinting defects born after ART was higher than in the total sample, 55.6% (10/18) and 34.5% (431/1,250), respectively. Conclusion This study found no association between ART and PWS. There was an increased frequency of twinning. The number of individuals with maternal disomy 15/imprinting defect was nearly double in the ART group compared to the total PWS participants. PMID:23928912

    Advanced Scientific Computing Research Computer Science FY 2010Report Center for Technology for Advanced Scientific Component Software: Distributed CCA State University of New York, Binghamton, NY, 13902 Summary The overall objective of Binghamton's involvement is to work on enhancements of the CCA environment, motivated by the applications and research initiatives discussed in the proposal. This year we are working on re-focusing our design and development efforts to develop proof-of-concept implementations that have the potential to significantly impact scientific components. We worked on developing parallel implementations for non-hydrostatic code and worked on a model coupling interface for biogeochemical computations coded in MATLAB. We also worked on the design and implementation modules that will be required for the emerging MapReduce model to be effective for scientific applications. Finally, we focused on optimizing the processing of scientific datasets on multi-core processors. Research Details We worked on the following research projects that we are working on applying to CCA-based scientific applications. 1. Non-Hydrostatic Hydrodynamics: Non-static hydrodynamics are significantly more accurate at modeling internal waves that may be important in lake ecosystems. Non-hydrostatic codes, however, are significantly more computationally expensive, often prohibitively so. We have worked with Chin Wu at the University of Wisconsin to parallelize non-hydrostatic code. We have obtained a speed up of about 26 times maximum. Although this is significant progress, we hope to improve the performance further, such that it becomes a practical alternative to hydrostatic codes. 2. Model-coupling for water-based ecosystems: To answer pressing questions about water resources requires that physical models (hydrodynamics) be coupled with biological and chemical models. Most hydrodynamics codes are written in Fortran, however, while most ecologists work in MATLAB. This

    1994-12-31

    This paper presents a conceptual framework and approach for establishing the US Environmental Protections Agency`s (EPA) environmental technology cooperation center. The topic is introduced with background information on events leading to the development and implementation of the center and brief overviews of the domestic and global environmental industries. The paper assesses several US environmental technology transfer programs and identifies significant, innovative, and instructive technology transfer methods which offer constructive models for the center. This examination focuses on several modes of public-private interaction required to facilitate the transfer of US environmental technologies into the international marketplace. Specific case studies of environmental technology cooperation initiatives include: the US-Asian Environmental Partnership (AEP), the US Environmental Training Institute (US ETI) and the recent International Environmental Technology Business Action Conference, which took place in Moscow last month. This information forms a basis for defining the needs, gaps and opportunities for the technology cooperation center. Technology transfer and cooperation programs must respond to a range of changing needs and requirements in the increasingly competitive and sophisticated global economy of the 1990`s. The environmental technology cooperation center concept developed by the US EPA offers an approach for enhancing public-private sector partnerships to improve domestic industry collaborations and enhance trans-national team-building. An innovative approach by EPA, in collaboration with other agencies and the private sector, can lead to the rapid introduction of a global network of national and regional centers to foster international environmental cooperation and team-building in the years ahead.

    Information technologies are evolving at a rapid pace in today's world. But the electronic technologies needed to transform today's libraries and information centers into electronic 'libraries without walls', where an end-user has instantaneous access to all the information needed from a desktop workstation, have not yet arrived. Even so, there are many technologies available today that can be applied in the library/information center environment to yield increased productivity. However, not all technologies are right for or successful in every environment. Mission, budget, infrastructure, client profiles, and staff skills are a few of the 'environmental' issues that must be considered when selecting and introducing new technologies into a particular information center. Key technologies used in libraries today are reviewed; it can be used as background for targeting technologies that could be successfully implemented in your own environment to further service goals. Before focusing on a selection of technologies, you must first focus on the strategic goal of your organization. The same technology is not right for every library/information center. An overview of technologies that are readily available and can be applied today is presented.

    2016-01-01

    The Society for Assisted Reproductive Technology (SART) method of embryo grad- ing is unique, simple, and widely practiced, and its use has been mandatory for SART membership programs since 2010. Developed by SART in 2006, the current embryo grading system categories, “good, fair, and poor,” are limited because they do not describe the best 1-2 embryos in the interest of keeping pace with the shift in clinical practice to be more selective and to transfer fewer embryos. This inspired us to conduct a review on the SART embryo grading system. In this retrospective study, the literature on evaluation of human embryo quality in gen- eral, and the SART method of evaluation in particular, were reviewed for the period of 2000 to 2014. A multifaceted search pertaining to methods of embryo grading and trans- fer using a combination of relevant terms [embryo, mammalian, embryo transfer, grade, grading, morphology, biomarkers, SART, and in vitro fertilization (IVF)] was performed. The inclusion and exclusion in this review were dictated by the aim and scope of the study. Two investigators independently assessed the studies and extracted information. A total of 61 articles were reviewed. Very few studies have evaluated the efficacy of the SART embryo grading method. The present study suggests the necessity for revision of the current SART grading system. The system, as it is now, lacks criteria for describing the cohort specific best embryo and thus is of limited use in single embryo transfer. The study foresees heightened descriptive efficiency of the SART system by implementing the proposed changes. Strengths and weaknesses of the SART embryo grading were identified. Ideas for selecting the best cohort-specific embryo have been discussed, which may trigger methodological improvement in SART and other embryo grading systems. PMID:27441045

    The purpose of this study was to examine whether dichorionic twins conceived by assisted reproductive technology (ART; intracytoplasmic sperm injection [ICSI], in vitro fertilization [IVF], gamete-intrafallopian tube transfer [GIFT]) have a higher risk of birth defects compared to dichorionic twins conceived naturally. We reviewed the medical records of 406 mothers with dichorionic twin pregnancies, who received continuous antenatal care from < or = 20 weeks of gestation and gave birth to infants after > or = 24 weeks of gestation in our institute. Birth defects were diagnosed at the time of hospital discharge according to the International Classification of Diseases, 10th Revision. Occurrence of birth defects was compared between twins conceived by ART and those conceived naturally using logistic regression analysis. Overall, 51 of 812 infants (51/812 = 6.2%) had birth defects. The incidence of birth defects in ART-conceived twins was significantly higher than that of naturally conceived twins with an odds ratio of 6.9 (95% confidence interval [CI] 2.1, 22.5), 3.7 (95% CI 1.2, 12.0), and 4.3 (95% CI 1.4, 14.3) for ICSI, IVF, and GIFT, respectively. The higher frequency of birth defects in ART-conceived twins was still significant after adjusting for higher maternal age in the ART group, with an adjusted odds ratio of 6.7 (95% CI 2.1, 21.9), 3.6 (95% CI 1.1, 11.5), and 3.7 (95% CI 1.2-11.8) for ICSI, IVF, and GIFT, respectively. Dichorionic twins conceived by ART, compared to dichorionic twins conceived naturally, had a much higher risk for birth defects diagnosed at hospital discharge. PMID:15193165

    Objective To investigate the risk of preterm birth among liveborn singletons to primiparas who conceived with assisted reproductive technology (ART) using four mutually exclusive categories of infertility (female infertility only, male infertility only, female and male infertility, and unexplained infertility) and to examine preterm birth risk along the gestational age continuum. Design Retrospective cohort study. Setting Not applicable. Patient(s) Singletons born to primiparas who conceived with or without ART. Intervention(s) None. Main Outcome Measure(s) Preterm (<37 weeks’ gestation) and preterm/early term birth <39 weeks’ gestation). Result(s) For the male infertility only, female infertility only, combined male and female infertility, and unexplained infertility groups, ART-conceived singletons were significantly more likely than non-ART singletons to be born preterm: adjusted odds ratio (aOR) 1.24 (95% CI, 1.13, 1.37), aOR 1.60 (95% CI, 1.50, 1.70), aOR 1.49 (95% CI, 1.35, 1.64), and aOR 1.26 (1.12, 1.43) respectively. Among infants whose mothers were diagnosed with infertility, the odds of preterm birth were highest between 28–30 weeks [female infertility only, aOR 1.95 (95% CI, 1.59, 2.39); male and female infertility: 2.21 (95% CI, 1.62, 3.00)] compared with infants in the general population. Within the ART population, singletons of couples with female infertility only were more likely to be born preterm than singletons born to couples with other infertility diagnoses. Conclusion(s) Among singleton births to primiparas, those conceived with ART had an increased risk for preterm birth, even when only the male partner had been diagnosed with infertility. The risk of preterm birth for ART-conceived infants whose mothers were diagnosed with infertility included the earliest deliveries. PMID:25707336

    Whether the type of culture media utilized in assisted reproductive technology has impacts on laboratory outcomes and birth weight of newborns in in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) was investigated. A total of 673 patients undergoing IVF/ICSI and giving birth to live singletons after fresh embryo transfer on day 3 from Jan. 1, 2010 to Dec. 31, 2012 were included. Three types of culture media were used during this period: Quinn's Advantage (QA), Single Step Medium (SSM), and Continuous Single Culture medium (CSC). Fertilization rate (FR), normal fertilization rate (NFR), cleavage rate (CR), normal cleavage rate (NCR), good-quality embryo rate (GQER) and neonatal birth weight were compared using one-way ANOVA and χ (2) tests. Multiple linear regression analysis was performed to determine the impact of culture media on laboratory outcomes and birth weight. In IVF cycles, GQER was significantly decreased in SSM medium group as compared with QA or CSC media groups (63.6% vs. 69.0% in QA; vs. 71.3% in CSC, P=0.011). In ICSI cycles, FR, NFR and CR were significantly lower in CSC medium group than in other two media groups. No significant difference was observed in neonatal birthweight among the three groups (P=0.759). Multiple linear regression analyses confirmed that the type of culture medium was correlated with FR, NFR, CR and GQER, but not with neonatal birth weight. The type of culture media had potential influences on laboratory outcomes but did not exhibit an impact on the birth weight of singletons in ART.

    BACKGROUND This 11th European IVF-monitoring report presents the results of assisted reproductive technology (ART) treatments initiated in Europe during 2007. METHODS From 33 countries, 1029 clinics reported 493 184 treatment cycles: IVF (120 761), ICSI (256 642), frozen embryo replacement (91 145), egg donation (15 731), preimplantation genetic diagnosis/preimplantation genetic screening (4638), in vitro maturation (660) and frozen oocytes replacements (3607). Overall, this represents a 7.6% increase since 2006, mostly related to an increase in all registers. IUI using husband/partner's (IUI-H) and donor (IUI-D) semen was reported from 23 countries: 142 609 IUI-H (+6.2%) and 26 088 IUI-D (+7.2%). RESULTS In 18 countries where all clinics reported, 376 971 ART cycles were performed in a population of 425.6million (886 cycles per million). The clinical pregnancy rates per aspiration and per transfer were 29.1 and 32.8% for IVF, and 28.6 and 33.0% for ICSI. Delivery rate after IUI-H was 10.2% in women aged < 40 years. In IVF/ICSI cycles, 1, 2, 3 and ≥4 embryos were transferred in 21.4, 53.4, 22.7 and 2.5% of cycles, with no decline in the number of embryos per transfer since 2006. The proportion of multiple deliveries (22.3: 21.3% twin and 1.0% triplet), did not decrease compared with 2006 (20.8%) and 2005 (21.8%). In women < 40 years undergoing IUI-H, twin deliveries occurred in 11.7% and triplets in 0.5%. CONCLUSIONS In comparison with previous years, the reported number of ART cycles in Europe increased in 2007; pregnancy rates increased marginally, but the earlier decline in the number of embryos transferred and multiple births did not continue.

    Today, there is growing interest in the potential epigenetic risk related to assisted reproductive technologies (ART). Much evidence in the literature supports the hypothesis that adverse pregnancy outcomes linked to ART are associated with abnormal trophoblastic invasion. The aim of this review is to investigate the relationship between epigenetic dysregulation caused by ART and subsequent placental response. The dialogue between the endometrium and the embryo is a crucial step to achieve successful trophoblastic invasion, thus ensuring a non-complicated pregnancy and healthy offspring. However, as described in this review, ART could impair both actors involved in this dialogue. First, ART may induce epigenetic defects in the conceptus by modifying the embryo environment. Second, as a result of hormone treatments, ART may impair endometrial receptivity. In some cases, it results in embryonic growth arrest but, when the development of the embryo continues, the placenta could bring adaptive responses throughout pregnancy. Amongst the different mechanisms, epigenetics, especially thanks to a finely tuned network of imprinted genes stimulated by foetal signals, may modify nutrient transfer, placental growth and vascularization. If these coping mechanisms are overwhelmed, improper maternal-foetal exchanges occur, potentially leading to adverse pregnancy outcomes such as abortion, preeclampsia or intra-uterine growth restriction. But in most cases, successful placental adaptation enables normal progress of the pregnancy. Nevertheless, the risks induced by these modifications during pregnancy are not fully understood. Metabolic diseases later in life could be exacerbated through the memory of epigenetic adaptation mechanisms established during pregnancy. Thus, more research is still needed to better understand abnormal interactions between the embryo and the milieu in artificial conditions. As trophectoderm cells are in direct contact with the environment, they deserve

    DNA methylation is a key epigenetic modification which is essential for normal embryonic development. Major epigenetic reprogramming takes place during gametogenesis and in the early embryo; the complex DNA methylation patterns are established and maintained by DNA methyltransferases (DNMTs). However, the influence of assisted reproductive technologies (ART) on DNA methylation reprogramming enzymes has predominantly been studied in mice and less so in human oocytes and embryos. The expression and localization patterns of the four known DNMTs were analysed in human oocytes and IVF/ICSI embryos by immunocytochemistry and compared between a reference group of good quality fresh embryos and groups of abnormally developing embryos or embryo groups after cryopreservation. In humans, DNMT1o rather than DNMT1s seems to be the key player for maintaining methylation in early embryos. DNMT3b, rather than DNMT3a and DNMT3L, appears to ensure global DNA remethylation in the blastocysts before implantation. DNMT3L, an important regulator of maternal imprint methylation in mouse, was not detected in human oocytes (GV, MI and MII stage). Our study confirms the existence of species differences for mammalian DNA methylation enzymes. In poor quality fresh embryos, the switch towards nuclear DNMT3b expression was delayed and nuclear DNMT1, DNMT1s and DNMT3b expression was less common. Compared with the reference embryos, a smaller number of cryopreserved embryos showed nuclear DNMT1, while a delayed switch to nuclear DNMT3b and an extended DNMT1s temporal expression pattern were also observed. The spatial and temporal expression patterns of DNMTs seem to be disturbed in abnormally developing embryos and in embryos that have been cryopreserved. Further research must be performed in order to understand whether the potentially disturbed embryonic DNMT expression after cryopreservation has any long-term developmental consequences.

    CONTEXT: Ovulation induction in patients with hypogonadotropic hypogonadism (HH) is a challenge to the treating physician. The threshold for ovarian response in HH may differ substantially from that of normal patients. To reach that threshold levels of follicle stimulating hormone, in a step-up protocol longer duration of stimulation is required in some cases so as to prevent multiple pregnancy and to eliminate the risk of ovarian hyperstimulation syndrome. AIM: To evaluate the duration of stimulation, quality of oocytes, and embryo, and the pregnancy outcome in the assisted reproductive technology (ART) cycles in patients with HH. MATERIALS AND METHODS: Over the period of 4 years, we had 14 patients with HH in whom 21 cycles of ovulation induction were done. Of these 7 patients underwent oocyte retrieval and intracytoplasmic sperm injection (ICSI). We present a retrospective study of these 7 patients who underwent ART to evaluate the duration of stimulation, quality of oocytes and embryo, and the pregnancy outcome. RESULTS: In the study group on ovulation induction with gonadotropins, only one patient had the duration of stimulation of the standard 12 days, the remaining 6 patients took ≥12 days to respond to stimulation (maxium being 54 days). Mean ET in these patients was 8.9 mm. Six patients had >70% good quality MII oocytes. One patient responded poorly and had only 2 good quality MII oocytes (50%). After ICSI procedure, resultant embryos were of grade 1 and 2 in all the patients irrespective of the duration of stimulation. Fertilization rate in these patients was 85% (except in one 50% fertilization rate), and the cumulative pregnancy rate was 68.6%. CONCLUSION: In the patients with HH the quality of oocytes and embryos, and the pregnancy rate is not affected even if the duration of stimulation is prolonged. PMID:26538857

    The vast amount of digital spatial data often required by a single user has created a demand for media alternatives to 1/2" magnetic tape. One such medium that has been recently adopted at the U.S. Geological Survey's EROS Data Center is the compact disc (CD). CD's are a versatile, dynamic, and low-cost method for providing a variety of data on a single media device and are compatible with various computer platforms. CD drives are available for personal computers, UNIX workstations, and mainframe systems, either directly connected, or through a network. This medium furnishes a quick method of reproducing and distributing large amounts of data on a single CD. Several data sets are already available on CD's, including collections of historical Landsat multispectral scanner data and biweekly composites of Advanced Very High Resolution Radiometer data for the conterminous United States. The EROS Data Center intends to provide even more data sets on CD's. Plans include specific data sets on a customized disc to fulfill individual requests, and mass production of unique data sets for large-scale distribution. Requests for a single compact disc-read only memory (CD-ROM) containing a large volume of data either for archiving or for one-time distribution can be addressed with a CD-write once (CD-WO) unit. Mass production and large-scale distribution will require CD-ROM replication and mastering.

The present article reports findings from the Center for Research and Education on Aging and Technology Enhancement (CREATE) on the use of technology among community-dwelling adults. The sample included 1,204 individuals ranging in age from 18–91 years. All participants completed a battery that included measures of demographic characteristics, self-rated health, experience with technology, attitudes toward computers, and component cognitive abilities. Findings indicate that the older adults were less likely than younger adults to use technology in general, computers, and the World Wide Web. The results also indicate that computer anxiety, fluid intelligence, and crystallized intelligence were important predictors of the use of technology. The relationship between age and adoption of technology was mediated by cognitive abilities, computer self-efficacy, and computer anxiety. These findings are discussed in terms of training strategies to promote technology adoption. PMID:16768579

    The provision of reproductive health services (RHS) by school-based health centers (SBHCs) is the subject of much controversy. Ideological differences about the role of schools in health care and the sexual activity of youth frame this debate. The purpose of this study was to determine the perspectives of key stakeholders related to access to RHS in SBHCs. Individual, semistructured interviews were conducted with 50 adult stakeholders. Template analysis yielded rich answers to the interview questions. Nine overarching themes emerged during thematic analysis. Subthemes and exemplar quotes revealed important insights into public opinion about RHS at SBHCs. Findings reflect strong stakeholder support for the inclusion of RHS in SBHCs as a way to promote teen sexual health. Nurses have an important role in influencing policies related to teen reproductive health such as those addressed in this study.

    In its search for higher level computer interfaces and more realistic electronic simulations for measurement and spatial analysis in human factors design, NASA at MSFC is evaluating the functionality of virtual reality (VR) technology. Virtual reality simulation generates a three dimensional environment in which the participant appears to be enveloped. It is a type of interactive simulation in which humans are not only involved, but included. Virtual reality technology is still in the experimental phase, but it appears to be the next logical step after computer aided three-dimensional animation in transferring the viewer from a passive to an active role in experiencing and evaluating an environment. There is great potential for using this new technology when designing environments for more successful interaction, both with the environment and with another participant in a remote location. At the University of North Carolina, a VR simulation of a the planned Sitterson Hall, revealed a flaw in the building's design that had not been observed during examination of the more traditional building plan simulation methods on paper and on computer aided design (CAD) work station. The virtual environment enables multiple participants in remote locations to come together and interact with one another and with the environment. Each participant is capable of seeing herself and the other participants and of interacting with them within the simulated environment.

    PubMed

    1999-04-01

    This article explores the reproductive health status of China. Since 1990, China has stepped up its efforts in promoting reproductive health and maternal and child health. Several studies demonstrated a remarkable progress made in this area. By 1997, maternal and infant mortality rates have declined, while the penetration rate for the immunization program and inpatient delivery rate increased. Despite these achievements, however, much remains to be done such as the lack of client-centered approaches to meet the increasingly diverse needs of the population for family planning services. A survey conducted in 1995 showed that the country's family planning program was focused primarily on demographic issues while little attention was given to reproductive health objectives. The situation improved when the State Planning Commission implemented its pilot program called the Quality of Care in Family Planning in China. The program yielded encouraging results including a reoriented philosophy towards reproductive health services, enhanced service facilities, informed choices for family planning methods, and the development of an operational information system. Another strategy adopted to address fertility and reproductive health issues was the implementation of adolescent reproductive health education as a required course for senior middle schools. Lastly, this article provided a brief overview of China's HIV/AIDS situation.

  6. From biopolitics to bioethics: church, state, medicine and assisted reproductive technology in Ireland.

    PubMed

    McDonnell, Orla; Allison, Jill

    2006-09-01

    This paper examines the emerging bioethical debate on assisted reproductive technology (ART) in Ireland, which is shaped by the long-standing contentious issue of abortion and the constitutional protection afforded to the 'unborn'. The focus of the paper is on the way in which the terms of this debate are shaped and constrained by the historical relations of power between church, state and medicine. Since the representation of Ireland as a post-Catholic, plural republic is becoming increasingly mainstream to cultural and political discourse, we pay particular attention to how the Catholic Church embraces bioethics as a meta frame or code for refocusing questions of values, beliefs and meanings to sustain the ideal of Ireland as a 'pro-life' and essentially Catholic nation. The Catholic Church is not simply asserting its voice of dissent in the context of public debate as one voice amongst a plurality of other voices, but to shape the emerging debate as a powerful, institutional actor. The opportunity to do so is afforded by the lack of public debate on bioethical issues and the exceedingly slow pace at which bioethics is moving towards an institutionalised framework in Ireland. These events can be explained by the legacy of the social power of the Catholic Church in Ireland and the direct and indirect influence it has long exercised over public policy vis-à-vis the state and its institutions, including medicine. There are two interconnected threads to the contextual analysis presented in our case study: first, the legacy of the social power wielded by the Catholic Church, and its slow and incremental demise reflected in the pace of secularisation in Ireland and the privatisation of morality; second, the emergence of a bioethical regulatory debate on ART, which is mired in the abortion controversy. Our analysis focuses on a number of key contradictions and tensions in the way in which the key institutions of church, state and medicine navigate their own positions

  7. Oocyte activation and phospholipase C zeta (PLCζ): diagnostic and therapeutic implications for assisted reproductive technology

    PubMed Central

    2012-01-01

    Infertility affects one in seven couples globally and has recently been classified as a disease by the World Health Organisation (WHO). While in-vitro fertilisation (IVF) offers effective treatment for many infertile couples, cases exhibiting severe male infertility (19–57%) often remain difficult, if not impossible to treat. In such cases, intracytoplasmic sperm injection (ICSI), a technique in which a single sperm is microinjected into the oocyte, is implemented. However, 1–5% of ICSI cycles still fail to fertilise, affecting over 1000 couples per year in the UK alone. Pregnancy and delivery rates for IVF and ICSI rarely exceed 30% and 23% respectively. It is therefore imperative that Assisted Reproductive Technology (ART) protocols are constantly modified by associated research programmes, in order to provide patients with the best chances of conception. Prior to fertilisation, mature oocytes are arrested in the metaphase stage of the second meiotic division (MII), which must be alleviated to allow the cell cycle, and subsequent embryogenesis, to proceed. Alleviation occurs through a series of concurrent events, collectively termed ‘oocyte activation’. In mammals, oocytes are activated by a series of intracellular calcium (Ca2+) oscillations following gamete fusion. Recent evidence implicates a sperm-specific phospholipase C, PLCzeta (PLCζ), introduced into the oocyte following membrane fusion as the factor responsible. This review summarises our current understanding of oocyte activation failure in human males, and describes recent advances in our knowledge linking certain cases of male infertility with defects in PLCζ expression and activity. Systematic literature searches were performed using PubMed and the ISI-Web of Knowledge. Databases compiled by the United Nations and World Health Organisation databases (UNWHO), and the Human Fertilization and Embryology Authority (HFEA) were also scrutinised. It is clear that PLCζ plays a fundamental role in

    Managing scientific data has been identified by the scientific community as one of the most important emerging needs because of the sheer volume and increasing complexity of data being collected. Effectively generating, managing, and analyzing this information requires a comprehensive, end-to-end approach to data management that encompasses all of the stages from the initial data acquisition to the final analysis of the data. Based on community input, we have identified three significant requirements. First, more efficient access to storage systems is needed. In particular, parallel file system and I/O system improvements are needed to write and read large volumes of data without slowing a simulation. Second, scientists require technologies to facilitate better understanding of their data, in particular the ability to effectively perform complex data analysis and searches over extremely large data sets. Furthermore, exploratory analysis requires techniques for efficiently selecting subsets of the data. Third, generating the data, collecting and storing the results, keeping track of data provenance, data post-processing, and analysis of results is a tedious, fragmented process. Tools for automation of this process in a robust, tractable, and recoverable fashion are required to enhance scientific exploration.

    To perform the ultra-precision centering and leveling operation of large surface under test in optical and mechanical precision measurements, a novel automatic centering and leveling turntable based on the aerostatic bearing technology is developed. In the functional module of centering, a planar aerostatic bearing and two micro-displacement actuators are utilized to achieve centering operation, and in the leveling functional module, a spherical aerostatic bearing, two microdisplacement actuators and a spring pivot are employed to realize the leveling operation. In the paper, the mathematical models of centering and leveling operation are obtained using coordinate transformation, and coupling between the centering and leveling operation is also analyzed. Furthermore, by using distance-measuring interferometer and autocollimator, the resolutions of centering and leveling operation are measured. Finally, errors of the centering and leveling operation are analyzed and the performance evaluation of the turntable is given. The experimental results show that, with 50Kg load, the leveling operation resolution is better than 1.2″; leveling operation range is +/-1° the centering operation resolution is better than 0.05μm centering operation range is about +/-5mm. The developed turntable can satisfy the requirements of ultra-precision, high resolution, wide range, frictionless, high load stiffness, stabilization and small driving force.

    This paper accompanies a poster that is being presented atthe SciDAC 2006 meeting in Denver, CO. This project focuses on leveragingscientific visualization and analytics software technology as an enablingtechnology for increasing scientific productivity and insight. Advancesincomputational technology have resultedin an "information big bang,"which in turn has createda significant data understanding challenge. Thischallenge is widely acknowledged to be one of the primary bottlenecks incontemporary science. The vision for our Center is to respond directly tothat challenge by adapting, extending, creating when necessary anddeploying visualization and data understanding technologies for ourscience stakeholders. Using an organizational model as a Visualizationand Analytics Center for Enabling Technologies (VACET), we are wellpositioned to be responsive to the needs of a diverse set of scientificstakeholders in a coordinated fashion using a range of visualization,mathematics, statistics, computer and computational science and datamanagement technologies.

    Incorporating technology with research is becoming increasingly important to enhance animal welfare in zoological settings. Video technology is used in the management of avian populations to facilitate efficient information collection on aspects of avian reproduction that are impractical or impossible to obtain through direct observation. Disney's Animal Kingdom(®) maintains a successful breeding colony of Northern carmine bee-eaters. This African species is a cavity nester, making their nesting behavior difficult to study and manage in an ex situ setting. After initial research focused on developing a suitable nesting environment, our goal was to continue developing methods to improve reproductive success and increase likelihood of chicks fledging. We installed infrared bullet cameras in five nest boxes and connected them to a digital video recording system, with data recorded continuously through the breeding season. We then scored and summarized nesting behaviors. Using remote video methods of observation provided much insight into the behavior of the birds in the colony's nest boxes. We observed aggression between birds during the egg-laying period, and therefore immediately removed all of the eggs for artificial incubation which completely eliminated egg breakage. We also used observations of adult feeding behavior to refine chick hand-rearing diet and practices. Although many video recording configurations have been summarized and evaluated in various reviews, we found success with the digital video recorder and infrared cameras described here. Applying emerging technologies to cavity nesting avian species is a necessary addition to improving management in and sustainability of zoo avian populations.

    Insights and recommendations arising from a study of the feasibility of combining the NASA Regional Dissemination Center (RDC) and Technology Application Team (Tateam) roles to form Regional Application Centers (RADC's) are presented. The apparent convergence of the functions of RDC's and Tateams is demonstrated and strongly supportive of the primary recommendation that an applications function be added to those already being performed by the RDC's. The basis of a national network for technology transfer and public and private sector problem solving is shown to exist, the skeleton of which is an interactive network of Regional Application Centers and NASA Field Centers. The feasibility of developing and extending this network is considered and the detailed ramifications of so doing are discussed and the imperatives emphasized. It is hypothesized that such a national network could become relatively independent of NASA funding within five years.

    The proliferation of online searching capabilities among its industrial clients, changes in marketing staff and direction, use of Dun and Bradstreet marketing service files, growth of the Annual Service Package program, and services delivered to clients at the NASA funded North Carolina Science and Technology Research Center are described. The library search service was reactivated and enlarged, and a survey was conducted on the NC/STRC Technical Bulletin's effectiveness. Several quotations from clients assess the overall value of the Center's services.

  19. Canada's Assisted Human Reproductive Act: is it scientific censorship, or a reasoned approach to the regulation of rapidly emerging reproductive technologies?

    After more than a decade of study, discussion and debate, the Canadian House of Commons and Senate have approved the Assisted Human Reproduction Act. Building on the earlier Bill C-47, which died on the order paper in 1997, the Act bans human cloning for reproductive or therapeutic purposes, payment for surrogacy arrangements, and trading in human reproductive materials or their use without informed consent. In addition, the Act significantly restricts research using human reproductive materials. This article compares the Act to legislative regimes in other nations with advanced human reproductive science. It concludes that while the Act has many laudable goals, it is flawed in that it tries to cover too much legislative ground. As a result it unreasonable impairs the ability of Canadian scientists to compete in areas such as stem cell research, and area that is expected to yield significant new approaches to treating human disease.
