    Are the main principles of international water law, as reflected in the Watercourses Convention, sufficiently equipped to motivate States to sustainably manage their freshwater resources? This article suggests that a more pronounced sustainable approach to these principles is desirable. The

  2. Tunisia: high fertility stalls development.

    Despite government policy enacted in 1964 to reduce fertility in order to hasten socioeconomic progress, population pressures continue to impair development in Tunisia. The birth rate fell 20% over the last 2 decades, but this accomplishment has been outweighed by a 50% decline in mortality rates. As a result, the rate of natural population increase has remained relatively constant at 2.5%/year. The initial decline in fertility that followed introduction of the national family planning program appears to have reached a plateau, explained in part by the resurgence of conservatism and religious fundamentalism and the consequent emphasis on women's childbearing roles. Unemployment in rural areas has led to widespread migration and unemployment is as high as 20% in the nonagricultural sector. Many young Tunisians lack adequate educational preparation to enter the labor force; in 1982, 27% of new job entrants could not read or write. The government's plan to decentralize development to stabilize population and achieve equilibrium between regions has been thwarted by the pace of population growth and limited resources. The rural regions where population is increasing the fastest are also the most difficult to reach with family planning programs. On the other hand, there have been some successes in this area when services have been adapted to the lifestyle and traditions of those in these isolated rural villages.

    Plant reproduction meetings often deal either with pre-fertilization processes such as flowering and pollen biology or post-fertilization processes such as embryogenesis and seed development. The Biochemical Society Focused Meeting entitled 'Regulation of Fertilization and Early Seed Development' was organized to close this gap and to discuss mechanistic similarities and future research directions in the reproductive processes shortly before, during and after fertilization. As an outcome of the workshop, invited speakers and a few selected oral communication presenters contributed focused reviews and technical articles for this issue of Biochemical Society Transactions. We provide here a short overview of the contents and highlights of the various articles.

  4. Intergenerational fertility correlations in contemporary developing counties.

    Murphy, Michael

    2012-01-01

    To estimate the magnitude of intergenerational continuities in total and effective fertility among women in a group of 46 contemporary developing countries. Information collected from 93,000 women aged 45-49 for estimation of maternal mortality in the demographic and health surveys (DHS) program is analyzed using Pearson product moment intergenerational fertility correlations. A positive but usually small intergenerational correlation is found for both completed fertility (CFS, total number of children born) and effective fertility (EFS, number of children surviving to age of reproduction). Although the developing countries are mainly located in sub-Saharan Africa, a similar pattern appears to hold for the Asian and Latin American countries included. Women in the second generation with no education have a stronger relationship with their parents' fertility than women with some education. The relationship is also stronger in rural than in urban areas and in countries with lower levels of development. Intergenerational correlations of completed fertility in both generations are marginally stronger than for effective fertility largely because the number of a woman's total sibs is more strongly related to her subsequent childbearing than her number of adult sibs. Values of intergenerational correlations for these countries are similar to published values for a number of Western pretransitional populations, but well below values in contemporary developed societies.

  5. Marriage and fertility in the developed countries.

    Science.gov (United States)

    Westoff, C F

    1978-12-01

    Most developed countries have reached zero population growth or less and, while population projections have often proved badly off-target, it seems that currently low fertility levels are the result of a long-term trend, which was interrupted in the last 100 years only by the still-unexplained postwar baby boom, and which will probably continue. The declining trend has accompanied economic development and modernization, which have transformed the economic value of children, making them a drain on resources rather than a source of income. The concomitant social changes seem largely irreversible: urban economy, the decline in traditional authority, universal, prolonged education, equality of women, low infant mortality, high consumer demands and sophisticated birth control technology are all here to stay. The theory that fertility exhibits a cyclical pattern based on people's perception of their degree of economic and social opportunity ignores the other elements affecting fertility behavior, especially the radical change in the status and expectations of women. Several trends in marriage and reproductive behavior in the U.S., Denmark and Sweden reinforce the presumption that fertility will remain low: declining number of marriages; postponement of marriage; increased tendency for unmarried couples to live together; instability of marriage shown by high divorce rates and declining remarriage rates; and increasing economic activity by women. The traditional institution of marriage is losing its economic, sexual, sociological and parenting rationales. Thus, declining fertility is both cause and consequence of changes in marriage. In Europe, where the decline is more advanced than in the U.S., governments are concerned that population growth will be too low and have instituted social welfare measures to induce and facilitate childbearing and childrearing. As women become more career-oriented, greater incentives will have to be provided. Manipulating immigration quotas

  6. Fertilizer application and root development analyzed by neutron imaging

    2013-01-01

    We studied the development of the soybean root system under different application of fertilizer applying neutron imaging technique. When neutron beam was irradiated, the root image as well as fertilizer imbedded in a thin aluminum container was clearly projected, since water amount in roots are higher than that in soil. Through image analysis, the development of root system was studied under different application of the fertilizer. The development of a main root with lateral roots was observed without applying fertilizer. When the fertilizer was homogeneously supplied to the soil, the morphological development of the root showed the similar pattern to that grown without fertilizer, in different to the amount of the fertilizer. In the case of local application of the fertilizer, lateral position or downward to the main root, the inhibition of the root growth was observed, suggesting that the localization of the fertilizer is responsible for reduction of the soybean yield.

  10. Development policy and the projects for fertility decline in Bangladesh.

    Cain, M; Lieberman, S S

    1983-09-01

    This paper reviews Bangladesh's government policy and suggests which development measures other than family planning services would increase contraceptive usage. It develops a framework for policy analysis by reviewing the fertility determinants literature in general, and that on Bangladesh. Conventional approaches, based on demographic transition theory (which presupposes economic development in the Third World will follow the historical path of the West, with attendant rates of urbanization and industrialization) and the microeconomic theory of consumer choice (whereby costs of children are measured only in the context of the internal workings of the household without regard to outside influences) are rejected in favor of an institutional framework, which emphasizes the productive value of children in the context of the institutional underpinnings of the costs and benefits of children. The analysis identifies the extremely harsh environment of risk, and the absence of effective forms of risk insurance, as crucial to understanding the persistence of Bangladesh's high fertility. It concludes that to ensure the country's fertility transition, the positive reproductive incentive associated with children as insurance against risk must be eliminated or reduced. Therefore policies with the greatest impact on reproductive behavior would either alter the environment of risk or introduce other effective means of adjusting to risk. Among the components of the development program in the Second Five Year Plan, rural public employment measures hold the greatest promise for reducing fertility. Such current initiatives have had program limitations, such as relief rather than long-term orientation and bottlenecks in communication and transportation. However, these efforts form a basis for developing a policy of guaranteed public works employment. This policy's potential flexibility, broad base, and success in other parts of South Asia (particularly Maharashtra State, India) make

    1992-08-01

    Rwanda's high fertility rate and very rapid population growth have a negative impact on the welfare of women. Traditionally, women in Rwanda won the respect of their in-laws by having many children, on whom they depended for social status, help in agricultural work, and support in old age. Women also played a very important role in agricultural production in addition to their daily household activities. Migration of men and young people to urban areas has left many women totally in charge of agricultural production and has further deprived them of their limited leisure time. Low income, legal obstacles, literacy, custom and other factors limit women's resulting from their inferior social and juridical status conditions their reproductive behavior despite the development of a family planning program dating to 1981. The low level of female education is an important factor; 33% of women vs. 61% of men are literate. 25% of Rwanda's budget is devoted to education, but population growth has impeded progress Illiteracy implies a lack of receptivity to new ideas, including family planning. A 1983 fertility study in Rwanda showed that marriage age increased with education, from 18.8 years for illiterate women to 19.5 for those within 3-5 years. The number of children declined with the educational attainment of the mother, as did infant mortality rates. Considering the physical labor that women carry out, their repeated pregnancies are a handicap to the promotion of their own and their family's health. The prevailing high fertility exacerbates nutritional problems; some 20% of infants weigh less that 2.5 kg at birth. Efforts have recently been made to recognize the contribution of women and to elevate their status, such as improving their access to education, raising the legal marriage to 21, and prohibiting polygamy. The National Office of Population was created in 1981 to study population problems and take action to resolve them. The national population policy adopted in

    Fertility was examined in 199 women exposed to internal and external radiation while employed in the radium watch-dial painting industry in Illinois between 1916 and 1929. In women with at least one live birth, mean log live-birth rate was significantly lower in the highest (estimated) ovarian-dose group (i.e., greater than or equal to 20 rem) than in the lowest group (<5 rem). In multiple regression analysis, intake dose (proportional to alpha-particle dose to ovaries) but not duration of employment (relevant to external gamma-ray dose to ovaries) was a statistically significant predictor of log live-birth rate. There was no evidence for an increase in fetal deaths with increasing ovarian dose level (rem). This suggests that the findings on live-birth rate may not involve post-implantation dominant lethal mutations, but pre-implantation losses could not be evaluated. Some possible explanations for these findings are discussed

    chambers exposed to 1 g will be removed and observed within the GPWS using a dissecting microscope and camera system. On the basis of egg rotation and egg appearance, the 'best' and 'second best' frogs will be selected to contribute additional eggs. Using the two best frogs, 22 egg chambers will be loaded with eggs and fertilized. Eleven chambers wil be incubated at microgravity and eleven will be incubated on the centrifuge. At various times during the flight, chambers will be removed from the FEU and transferred to the GPWS where a formaldehyde-based fixative will be injected in order to preserve important developmental stages for in depth study following the flight. Five of the 22 chambers plus the eight fertilization test chambers will be returned to Earth with live tadpoles. The swimming behavior of these free swimming tadpoles will be examined within several hours of landing and some will be fixed for a detailed analysis of their inner ear, the otolity, the animals 'balance system.' Lychakov and Vinikov reported an increase in otolith size in tadpoles that developed (but were not fertilized) in space. Live tadpoles from the SL-J flight will be raised through metamorphsis for studies of maturation including an analysis of the effects of space flight on their ability to produce normal progency. Following the flight, the fixed embryos will be serially sectioned and stained using procedures that were developed for this experiment. The embroys fixed at the 2-4 cell stage will be examined for the distribution of cytoplasmic contents, including the various classes of yolk platelets, and the location and shape of the cleavage furrows. The gastrulae will be assessed for the normality of the complex cellular rearrangements that constitute blastopore formation and involution, i.e., the differentiation of the embryo into its specialized body parts. Using a new procedure, the gastrulae will be bleached which will enable the initial sperm entry point (SEP) to be located. The

    We extend the literature on endogenous lifetime and economic growth by Chakraborty (2004) and Bunzel and Qiao (2005) to endogenous fertility. We show that development traps due to underinvestments in health cannot appear when fertility is an economic decision variable and the costs of children are represented by a constant fraction of the parents' income used for their upbringing.

  17. Economic recession and fertility in the developed world.

    Science.gov (United States)

    Sobotka, Tomáš; Skirbekk, Vegard; Philipov, Dimiter

    2011-01-01

    This article reviews research on the effects of economic recessions on fertility in the developed world. We study how economic downturns, as measured by various indicators, especially by declining GDP levels, falling consumer confidence, and rising unemployment, were found to affect fertility. We also discuss particular mechanisms through which the recession may have influenced fertility behavior, including the effects of economic uncertainty, falling income, changes in the housing market, and rising enrollment in higher education, and also factors that influence fertility indirectly such as declining marriage rates. Most studies find that fertility tends to be pro-cyclical and often rises and declines with the ups and downs of the business cycle. Usually, these aggregate effects are relatively small (typically, a few percentage points) and of short durations; in addition they often influence especially the timing of childbearing and in most cases do not leave an imprint on cohort fertility levels. Therefore, major long-term fertility shifts often continue seemingly uninterrupted during the recession—including the fertility declines before and during the Great Depression of the 1930s and before and during the oil shock crises of the 1970s. Changes in the opportunity costs of childbearing and fertility behavior during economic downturn vary by sex, age, social status, and number of children; childless young adults are usually most affected. Furthermore, various policies and institutions may modify or even reverse the relationship between recessions and fertility. The first evidence pertaining to the recent recession falls in line with these findings. In most countries, the recession has brought a decline in the number of births and fertility rates, often marking a sharp halt to the previous decade of rising fertility rates.

  1. Development of Malaysian women fertility index: Evidence from Shannon's entropy

    Science.gov (United States)

    2017-11-01

    A fertility rate is a measure of the average number of children a woman will have during her childbearing years. Malaysia is now facing a population crisis and the fertility rate continues to decline. This situation will have implications for the age structure of the population where percentages of senior citizens are higher than percentages of people aged below 5 years old. Malaysia is expected to reach aging population status by the year 2035. As the aging population has a very long average life expectancy, the government needs to spend a lot on medical costs for senior citizens and need to increase budgets for pensions. The government may be required to increase tax revenues to support the growing older population. The falling fertility rate requires proper control by relevant authorities, especially through planning and implementation of strategic and effective measures. Hence, this paper aims to develop a fertility index using Shannon's entropy method. The results show that Selangor, Johor, and Sarawak are among the states with the highest values of the fertility index. On the other end of the spectrum, Terengganu, W.P. Labuan, and Perlis are ranked in the last positions according to the fertility index. The information generated from the results in this study can be used as a primary source for the government to design appropriate policies to mitigate dwindling fertility rates among Malaysian women.

    2014-05-01

    To review the management of postvasectomy fertility options by urologists with vs without andrology fellowship and compare the features of practice in the USA vs UK. We conducted an audit of all American Urological Association-affiliated urologists regarding their practice in managing men requesting vasectomy reversal (VR). Standards of practice were assessed against 10 index parameters deemed, by 1 UK study, to reflect best practice. Fisher exact test was used to test the hypothesis that management of postvasectomy fertility options and practice of VR are no different when undertaken by urologists with vs without andrology training and no different in the USA vs UK. Three hundred twenty-five of 645 US respondents (50.4%) practiced VR vs 178 of 213 (83.6%) in the UK; only 11.9% in the US and 10% in the UK performed >25 and >15 (P <.0001) VR/year, respectively. Compared with the UK urologists the US urologists offered more detailed information on all fertility options and/or outcomes, used microsurgical techniques more often, but less frequently counseled couples together, and referred patients to specialist centers for in vitro fertilization with intracytoplasmic sperm injection (P <.0001-.05). Only 74 of the US and 61 of the UK urologists were fellowship-trained in andrology. Most non-fellowship-trained urologists, in both the countries, performed <5 VR/year and were, statistically, significantly less likely to counsel couples about all fertility options, be conversant in in vitro fertilization with intracytoplasmic sperm injection, provide individualized outcomes data, and use microsurgical techniques (P <.0001-.05). Significant differences exist in the standards of practice between both the US and UK urologists performing VR. Concordance with the indices of "best practice" improves with andrology training and increasing number of procedures performed. Copyright © 2014 Elsevier Inc. All rights reserved.

  4. Fertility behavior in developing economies: an investment approach.

    Science.gov (United States)

    Chernichovsky, D

    1982-01-01

    By studying intergenerational benefits from children, this paper shows that the economic analysis of fertility behavior in developing economics can provide a systematic discussion of this behavior. The major hypotheses set forth are: 1) the effect of income on fertility depends on the source and timing of income; 2) in a lifetime context, parents, or would-be parents, who have higher incomes at young ages compared with the income they anticipate at old age, are expected to have a higher demand for children; and 3) the reverse of the latter is predicted for parents who anticipate relatively higher incomes at old age. These hypotheses follow the idea that, in the absence of other appropriate means for intertemporal transfers of wealth, parents even out the lifetime welfare through fertility behavior. Under these circumstances, fertility rates are expected to increase in communities where children abandon their traditional commitments to their aging parents, as may happen during periods of economic and cultural transition. A decline in mortality rates will induce lower fertility. This model suggests that a tax-financed social security scheme along with family planning will be conducive to a reduction in fertility. A test on data from an Indian village in 1968-69 suggests that in a traditional setting there is a correlation between household welfare, measured by income or assets, and the presence of grown children. Income has a positive effect on fertility when the parents' incomes comes from labor rather than human and nonhuman capital which provides income at later stages of life. Longitudinal data depicting income, savings, and fertility patterns over time should prove more promising in exploring the issues discussed.

The aim of this study was tocompare fertilization and embryo development in frozen-thawed oocytes to their fresh siblings inwomen undergoing in vitro fertilization (IVF and embryo transfer (ET.Materials and Methods: Eleven infertile women undergoing infertility treatment, between theages of 24 to 37 years (mean ± SD = 31.6 ± 3.5, were included in this study. Mature oocytesfrom each patient were randomized into cryopreserved and fresh groups prior to intracytoplasmicsperm injection (ICSI. One hundred and thirty nine oocytes were retrieved, of which 105 were atmetaphase II (MII. Forty- five fresh MII oocytes were kept in culture whereas their sibling 60 MIIoocytes were cryopreserved using a slow cooling protocol. The frozen oocytes remained in LN2for 2 hours before thawing. ICSI was performed 1-2 hours after thawing for frozen oocytes and 4-5hours after retrieval for fresh oocytes. Fertilization and embryo development were compared.Results: Following thawing, 31 oocytes (51.6 % survived and 22 fertilized (79% while 32 freshoocytes fertilized upon ICSI (71%. The mean ± SE scores for embryos developing from frozenthawedoocytes were significantly lower at 48 and 72 hours post-ICSI than for embryos resultingfrom fresh oocytes (p<0.05.Conclusion: Our data demonstrated that oocyte freezing resulted in acceptable survival ratesfollowing cryopreservation, and similar fertilization rates following ICSI as compared to the freshsibling oocytes. However the number of blastomeres and the embryo quality on day three wassuperior in embryos from fresh oocytes when compared to the frozen oocytes.

The first part of this international round table of the French gas association's annual conference was devoted to whether they have all necessary assets, especially in terms of know-how and new technologies. In the second part of this round table, gas industry leaders presented their ambitions and strategies on the international scene. The questions discussed related to the main areas of development from both business and geographic viewpoints; to the underlying factors such as expertise, technological know-how, market risks and potential, strategic alliances.

    Personas have become a popular method in new product development. Personas have traditionally, and are still, primarily created to represent users from a single national culture at a time during the design process. This, however, is unsatisfactory for companies operating on a global market...... as they show an increasing interest in international personas. However, research on personas in a global context is limited. To address this gap, this paper provides an overview of extant research on international personas. Secondly, it presents an empirical study on challenges Danish IT companies experience...... when using the persona method to collect and present insights about their international users. A key finding in both the literature review and the empirical study was the ambiguity concerning the concept of culture. Therefore, the paper draws on theories about culture, and especially practice theory...

    Genome editing technology, including zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeat (CRISPR)/Cas, has enabled far more efficient genetic engineering even in non-human primates. This biotechnology is more likely to develop into medicine for preventing a genetic disease if corrective genome editing is integrated into assisted reproductive technology, represented by in vitro fertilization. Although rapid advances in genome editing are expected to make germline gene correction feasible in a clinical setting, there are many issues that still need to be addressed before this could occur. We herein examine current status of genome editing in mammalian embryonic stem cells and zygotes and discuss potential issues in the international regulatory landscape regarding human germline gene modification. Moreover, we address some ethical and social issues that would be raised when each country considers whether genome editing-mediated germline gene correction for preventive medicine should be permitted.

    We report mutants in Arabidopsis thaliana (fertilization-independent seed: fis) in which certain processes of seed development are uncoupled from the double fertilization event that occurs after pollination. These mutants were isolated as ethyl methanesulfonate-induced pseudo-revertants of the pistillata phenotype. Although the pistillata (pi) mutant has short siliques devoid of seed, the fis mutants in the pi background have long siliques containing developing seeds, even though the flowers remain free of pollen. The three fis mutations map to loci on three different chromosomes. In fis1 and fis2 seeds, the autonomous endosperm nuclei are diploid and the endosperm develops to the point of cellularization; the partially developed seeds then atrophy. In these two mutants, proembryos are formed in a low proportion of seeds and do not develop beyond the globular stage. When FIS/fis plants are pollinated by pollen from FIS/FIS plants, ≈50% of the resulting seeds contain fully developed embryos; these seeds germinate and form viable seedlings (FIS/FIS). The other 50% of seeds shrivel and do not germinate; they contain embryos arrested at the torpedo stage (FIS/fis). In normal sexual reproduction, the products of the FIS genes are likely to play important regulatory roles in the development of seed after fertilization. PMID:9108133

    Full Text Available This study reviewed and analyzed the specific practices, implementation effects and applicable conditions of fertilizer reduction policies in the EU, US and Japan, explored the common laws and general conditions in the formulation of environmental orientation, and pro vided feasible policy recommendations for the formulation of fertilizer reduction policies in China. This study showed that fertilizer reduction policies in each country had their own advantages and disadvantages, and the applicable conditions were different. The EU's command and control policy was applicable to the situation of less farm households and the same agricultural planting type or farm type. The economic in centive policy in the US was applicable to the situation of more farm households, relatively perfect agricultural market system and sensitive price formation mechanism, while the public participation policy in Japan was applicable to regions with more relevant agricultural groups and strong economy. China should learn from each of these policies and make a comprehensive choice in the formulation of fertilizer reduc tion policies. Therefore, China should proceed from improving the agricultural price mechanism and the pollution-free agricultural products certification system as well as encouraging and supporting the development of large scale production units, and then promote the adoption of environmentally friendly technology through the guidance of market mechanism, ensure the effective implementation of environmental stan dards through farmers' integration and improve farmers' environmental awareness through propaganda guidance, so as to ensure the effective implementation of different types(command and control policy, economic incentive policy and public participation policyof fertilizer reduc tion policies.

    For more than a decade, sodium cooled breeder reactors have now been in the focus of advanced nuclear power development in the major industrialized countries. In the sixties, a total of seven small experimental nuclear power stations were commissioned. Two of these have been shut down in the meantime, the others continue to work satisfactorily, their main purpose being the development of fuel elements. The years 1972-1974 saw the commissioning of the prototype power stations in the 300 MWe power category in France, the United Kingdom and the Soviet Union. Presently, other experimental reactors are under construction in the Federal Republic of Germany, Italy, Japan, the United States, plus another Soviet 600 MWe prototype reactor and the SNR 300 DeBeNeLux prototype at Kalkar. A comparison of the technological features either implemented or planned in the prototype and experimental power plants and of their fuel elements reveals a remarkable similarity in the basic concepts pursued in different countries. The two types of breeder reactors, viz. the loop and the pool types, show a closer resemblance to each other than do pressurized and boilling water reactors. The growing awareness of administrative problems emerging in the approaching phase of the introduction of large breeder power stations in a number of European countries has recently led to a streamlining effort in the structure of industries and to tentative steps towards international cooperation on a broad basis.

    Infertility is one of the most difficult life experiences that a couple might encounter. Infertility as a bio-psycho-social phenomenon, could influence all aspects of life. While paying special attention to the psychological aspects of infertility in couples; many studies have investigated the non-clinical aspects of infertility, however, they rarely have evaluated the psychosocial development of infertile versus fertile men. We aimed to study the effects of infertility on psychosocial development in men. In fact, we designed the study based on "Erikson's theory of psychosocial development". We focused on the relationship between psychosocial development and some self-conceived indices. For this purpose, we divided the participants volunteers into two groups of cases (80 infertile men) and controls (40 fertile men) and asked them to complete a 112 (questions questionnaire based on "self description"). The statistical analysis was performed by SPSS (version 13) using independent t-test, Pearson correlation coefficient and analysis of covariance. A p-value stages (p stages. Infertility as a phenomenon had its own effects on the psychosocial development of infertile men. However, good coping skills are powerful tools to manage these myriad of feelings surrounding infertile men.

    Sever, D M; Moriarty, E C; Rania, L C; Hamlett, W C

    2001-04-01

    This study provides the first descriptions of sperm storage at the tissue and cellular levels in a female frog or toad. Oviducal anatomy was studied by light and electron microscopy in Ascaphus truei from north coastal California. Ascaphus truei is one of the few species of anurans in which fertilization is internal. Unlike other anurans with internal fertilization, however, mating in A. truei consists of a unique combination of amplectic and copulatory mechanisms that we term "copulexus." Posterior to a short, aglandular infundibular region, the oviduct possesses: 1) a proximal, convoluted ampullary region where intrinsic tubular glands secrete gelatinous envelopes around eggs; 2) a middle ovisac region where fertilization occurs; and 3) a distal oviducal sinus formed by medial junction of the ovisacs. Sperm storage tubules (SSTs) occur in the anterior portions of the ovisacs and consist of simple tubular glands. SSTs and the rest of the oviducal lining stain positively with the periodic acid-Schiff's procedure for neutral carbohydrates and this reaction is especially intense in reproductively active females. Sperm were found in the SSTs of gravid females as well as some nonvitellogenic females. The sperm are in orderly bundles in the SSTs, and although occasionally sperm nuclei were embedded in the epithelium, no evidence for spermiophagy was found. Oviducal sperm storage in A. truei is homoplastic, with closest structural similarities to squamate reptiles. Oviduct/sperm design constraints appear to limit the options for expression of features associated with oviducal sperm storage. Copyright 2001 Wiley-Liss, Inc.

    Smith, C C; Ryan, M J

    2010-08-01

    Species with alternative reproductive strategies are characterized by discrete differences among males in suites of traits related to competition for fertilizations. Models predict sneaker males should allocate more resources to their ejaculates because they experience sperm competition more frequently and often occupy a disfavoured 'role' owing to subordinance in intramale competition and female preferences for larger males. We examined whether sperm number and quality differed between male strategies in the internally fertilized fish Xiphophorus nigrensis and explored the relationship between sperm morphology and performance. We found sneaker males had similar testes sizes compared to courting males but ejaculates with both more viable and longer lived sperm. Sneaker sperm also had longer midpieces, which was positively correlated with both velocity and longevity. Our study suggests that the evolution of sperm quantity and quality can be decoupled and that the sperm morphology is likely to play an important role in mediating sperm competition through its effects on sperm performance.

    Female labor supply has been changed dramatically in the recent yr. In this study, we examined the effects of development on the relationship between fertility and female labor supply. We used data of population and housing census of Iran and estimated three separate models. To do this we employed Logistic Regressions (BLR). The estimation results of our study showed that there was a negative relationship between fertility rate and female labor supply and there are some differences for this relationship in three models. When fertility rate increases, FLS would decreases. In addition, for higher fertility rates, the woman might be forced to work more because of the economic conditions of her family; and negative coefficients of the fertility rate effects on FLS would increase with a diminishing rate.

    2017-09-01

    What progress has been made in fertility preservation (FP) over the last decade? FP techniques have been widely adopted over the last decade and therefore the establishment of international registries on their short- and long-term outcomes is strongly recommended. FP is a fundamental issue for both males and females whose future fertility may be compromised. Reproductive capacity may be seriously affected by age, different medical conditions and also by treatments, especially those with gonadal toxicity. There is general consensus on the need to provide counselling about currently available FP options to all individuals wishing to preserve their fertility. An international meeting with representatives from expert scientific societies involved in FP was held in Barcelona, Spain, in June 2015. Twenty international FP experts belonging to the American Society of Reproductive Medicine, ESHRE and the International Society of Fertility Preservation reviewed the literature up to June 2015 to be discussed at the meeting, and approved the final manuscript. At the time this manuscript was being written, new evidence considered relevant for the debated topics was published, and was consequently included. Several oncological and non-oncological diseases may affect current or future fertility, either caused by the disease itself or the gonadotoxic treatment, and need an adequate FP approach. Women wishing to postpone maternity and transgender individuals before starting hormone therapy or undergoing surgery to remove/alter their reproductive organs should also be counselled accordingly. Embryo and oocyte cryopreservation are first-line FP methods in postpubertal women. Metaphase II oocyte cryopreservation (vitrification) is the preferred option. Cumulative evidence of restoration of ovarian function and spontaneous pregnancies after ART following orthotopic transplantation of cryopreserved ovarian tissue supports its future consideration as an open clinical application.

  7. The impact of development and population policies on fertility in India.

    Science.gov (United States)

    Jain, A K

    1985-01-01

    This article examines the impact of development and population policies on fertility decline and regional variations in India during the 1970s. Indicators of development at the household level include female literacy and education, infant mortality, and poverty; at the village level they include availability of such social services as schools, medical facilities, and transportation and communication facilities. Multiple regression analysis of data aggregated at the state level demonstrates that conditions conducive to fertility decline include high adult female literacy and low infant mortality as indicators of social development, and high contraceptive use and, to a lesser extent, high female age at marriage as proximate determinants of fertility. There are reasons to believe that India's national family planning program contributed to the decline in fertility observed since the 1960s. The pace of fertility decline in the future will depend upon the pace of infant mortality decline, enhancement in female education, and improvements in family planning programs.

  9. Sperm-attractant peptide influences the spermatozoa swimming behavior in internal fertilization in Octopus vulgaris.

    Marine invertebrates exhibit both chemokinesis and chemotaxis phenomena, induced in most cases by the release of water-borne peptides or pheromones. In mollusks, several peptides released during egg-laying improve both male attraction and mating. Unlike other cephalopods, Octopus vulgaris adopts an indirect internal fertilization strategy. We here report on the identification and characterization of a chemoattractant peptide isolated from mature eggs of octopus females. Using two-chamber and time-lapse microscopy assays, we demonstrate that this bioactive peptide is able to increase sperm motility and induce chemotaxis by changing the octopus spermatozoa swimming behavior in a dose-dependent manner. We also provide evidence that chemotaxis in the octopus requires the presence of extracellular calcium and membrane protein phophorylation at tyrosine. This study is the first report on a sperm-activating factor in a non-free-spawning marine animal.

This point is widely recognised by analysts and policy makers, but is greatly underestimated in its qualitative and quantitative significance, and in the investment allocations of many developing country and donor governments."--Commission on Macroeconomics and Health The international health development scene has changed rapidly during the past 5 years. From being a merely bilateral effort together with a few multilateral organisations and many NGOs new global partnerships have entered the scene and become major funding agencies. The provision of aid has also changed from small-scale project basis to financial support of large programmes. The purpose of this article is to describe some of the major transformations taken place in the organising, delivery and objective of international health development. But before presenting the new international health development agenda, a short introduction to the challenges inducing the need for renewed thinking about international aid is shortly presented.

    The emergence of open networked models made possible by digital technology has the potential to transform international development. Open network structures allow people to come together to share information, organize, and collaborate. Open development harnesses this power, to create new organizational forms and improve people's lives; it is not only an agenda for research and practice but also a statement about how to approach international development. In this volume, experts explore a variety of applications of openness, addressing challenges as well as opportunities. Open development requires new theoretical tools that focus on real world problems, consider a variety of solutions, and recognize the complexity of local contexts. After exploring the new theoretical terrain, the book describes a range of cases in which open models address such specific development issues as biotechnology research, improving education, and access to scholarly publications.

    McArthur, John W; McCord, Gordon C

    2017-07-01

    This paper estimates the role of agronomic inputs in cereal yield improvements and the consequences for countries' processes of structural change. The results suggest a clear role for fertilizer, modern seeds and water in boosting yields. We then test for respective empirical links between agricultural yields and economic growth, labor share in agriculture and non-agricultural value added per worker. The identification strategy includes a novel instrumental variable that exploits the unique economic geography of fertilizer production and transport costs to countries' agricultural heartlands. We estimate that a half ton increase in staple yields generates a 14 to 19 percent higher GDP per capita and a 4.6 to 5.6 percentage point lower labor share in agriculture five years later. The results suggest a strong role for agricultural productivity as a driver of structural change.

  17. Fertility of Czech Females Could Be Lower than Expected: Trends in Future Development of Age-Specific Fertility Rates up to the Year 2050

    Directory of Open Access Journals (Sweden)

    Ondřej Šimpach

    2015-03-01

    Full Text Available Fertility is an essential aspect of reproduction or population replacement of each country. The challenge for demographers is to model fertility and also to estimate its potential future level for the purposes of population projections. In the case of the Czech Republic we have the population projections provided by the Czech Statistical Office (CZSO with overlooking of the total fertility rate in low, medium and high variant. These estimates despite being based on expert judgments, seem to be too positive compared to the past development of the time series of age-specific fertility rates. The aim of this paper is to assess the situation of fertility in the Czech Republic, to analyse the past development of the time series of age-specific fertility rates using one-dimensional Box-Jenkins models and multidimensional stochastic Lee-Carter approach. Together with found trend in time series and principal components estimated by Lee-Carter’s model a forecasts of age-specific fertility rates up to the year 2050 is constructed. Th ese rates are lower than those provided by CZSO in its three variants of the Czech Republic’s population projection, and therefore we discuss the causes at the end of the paper. We would like to point out that the potential future development of Czech females fertility could be lower than which are currently expected.

  18. Impact of fertilizers on background radioactivity level of two newly developed farms in Western Desert, Egypt

    Ahmad, F.

    2006-01-01

    A survey of soil and plants were carried out to determine the environmental gamma background radiation levels of two newly developed farms in western desert area, Egypt. The materials and the standards were analyzed by gamma spectroscopy in which a shielded high purity germanium detector has been used to measure the natural concentration of 238 U, 232 Th and 40 K activities in the samples. The radionuclide contents in some commercial fertilizers have been determined. The results of analysis of specific activities in the fertilizers under study were 1.27-950.09 Bq/Kg for 238 U, 0.73 -162.16 Bq/Kg for 232 Th and 10.22- 23845.24 Bq/Kg for 40 K. All natural soil samples showed low activity concentrations. The concentrations of 238 U (6.13-38.84 Bq/Kg) and 232 Th (2.58-25.69 Bq/Kg) were quite similar, while that of 40 K (113.91-9314.11 Bq/Kg) was the highest for plant samples. Some of the results obtained were higher than the permissible international radioactivity levels. It is suitable in this regard to compare the activity values for the imported fertilizers and that fabricated in Egypt. The absorbed dose rate and the radium equivalent activity concentration were found to be 1.91-1027 n Gy/h and 4.02-1840.98 Bq/Kg, respectively, for fertilizers samples. For soil and plant samples, the results were 11.86-415.29 n Gy/h and 24.20-750.52 Bq/Kg for the absorbed dose rate and the radium equivalent activity concentration, respectively, and the banana plant contained the largest values. The present study presents actual data from investigations of the plant-soil transfer of the primordial radio nuclides for some fruits growing at these soils. The transfer factors of 0.35-1.821 for 238 U, 0.227-0.480 for 232 Th and 1.95-31.85 for 40 K were obtained. The increase of the transfer of 40 K reflected its great uptake to the fruits. The observed plant-soil factors were varied widely, mainly as a result of different soil, vegetation types and environmental conditions. Taking into

To improve awareness about the potentially modifiable factors that affect fertility and reproductive outcomes, ‘Your Fertility’, a fertility health promotion programme funded by the Australian Government, was established in 2011. This paper describes the development and evaluation of the reach of the Your Fertility programme from its inception in 2011 to June 2016. Systematically recorded outcomes for the programme’s key focus areas and Google Analytics data were collated. Key achievements include developing and maintaining an internationally renowned website that experiences high growth and demand for fertility-related information; by 2016, over 5 million users had viewed more than 10 million webpages, and over 96,000 users had engaged in programme messages across social media. Programme messages have reached more than 4 million Australian social media users, and a potential audience of 150 million through media coverage across more than 320 media features. More than 4200 education and health professionals have completed online learning modules, and external partnerships have been established with 14 separate organizations. Data collected over 5 years indicate that the Your Fertility programme meets a need for targeted, evidence-based, accessible fertility-related information.

    The development of bio fertilizer products, which involve incorporation of known microorganisms with desired functions, requires sterilisation of the carriers or substrates. Conventional sterilisation method using heat treatment or autoclaving has its limitations, especially in mass production of bio fertilizers. The Forum for Nuclear Cooperation in Asia (FNCA) through its Bio fertilizer Project Group encourages the use of gamma irradiation for carrier sterilisation, capitalising on the quality of the final products following proper sterilisation. Gamma irradiation at doses of 30 to 50 kGy was found suitable for sterilisation, depending on the carrier materials. More deliberation is needed for bio fertilizer companies far away from the gamma irradiation facilities to utilise gamma irradiation services for their bio fertilizer carriers, on aspects of cost of transportation, sterilisation, storage and convenience of use. Evaluation of bio fertilizer products on crops in the field need to be conducted to assess their efficacy. Several isotope-aided trials have been conducted to evaluate nutrient use efficiency of several formulations of Nuclear Malaysia bio fertilizer products, involving vegetable and herbal crops, with varying results. The paper highlights trials in Nuclear Malaysia and Cameron Highlands. Presently, product evaluation is limited to use of the stable isotope, nitrogen-15, in particular when considering radiation safety in field trials. Having joint trials involving potential end users is still a challenge. (author)

    The aim of this paper is to present a synthesis of the main developments and drivers of international bioenergy trade in IEA Bioenergy Task 40 member countries, based on various country reports written by Task 40 members. Special attention is given to pellet and ethanol trade. In many European countries such as Belgium, Finland, the Netherlands, Sweden and the UK, imported biomass contributes already significantly (between 21% and 43%) to total biomass use. Wood pellets are currently exported by Canada, Finland and (to a small extent) Brazil and Norway, and imported by Sweden, Belgium, the Netherlands, and the UK. In the Netherlands and Belgium, pellet imports nowadays contribute to a major share to total renewable electricity production. Trade in bio-ethanol is another example of a rapidly growing international market. With the EU-wide target of 5.75% biofuels for transportation in 2010 (and 10% in 2020), exports from Brazil and other countries to Europe are likely to rise as well. Major drivers for international bioenergy trade in general are the large resource potentials and relatively low production costs in producing countries such as Canada and Brazil, and high fossil fuel prices and various policy incentives to stimulate biomass use in importing countries. However, the logistic infrastructure both in exporting and importing countries needs to be developed to access larger physical biomass volumes and to reach other (i.e. smaller) end-consumers. It is concluded that international bioenergy trade is growing rapidly, far beyond what was deemed possible only a few years ago, and may in the future in some Task 40 countries surpass domestic biomass use, especially for specific applications (e.g. transport fuels).

    The author investigates the extent to which both absolute and relative poverty affect population growth in developing countries. Aggregate data from U.N. sources for 26 countries at various stages of the fertility transition are used. The results indicate that the most significant steps in reducing fertility would be more effective provision of basic human needs and reforms in land tenure. The need to distinguish between absolute and relative poverty in formulating population policies is noted.

    In his Fourth Report on the Identification of Customary International Law (2016), Special Rapporteur Michael Wood confirmed that ‘[i]n certain cases, the practice of international organizations also contributes to the expression, or creation, of rules of customary international law.......’ That the practice of international organizations can be relevant when identifying customary international law is relatively uncontroversial. The practice of states within international organizations such as the UN General Assembly, for example, may contribute to the development of custom. Yet, there is little...... discussion about whether and how the practice of international organizations as such may contribute to the development of customary international law. This contribution discusses the organization that is the most capable of contributing to the development of customary international law in its own right...

    1988-01-01

    Programs for the development of high-temperature gas-cooled reactor (HTGR) technology over the past 30 years in eight countries are briefly described. These programs have included both government sector and industrial sector participation. The programs have produced four electricity-producing prototype/demonstration reactors, two in the United States, and two in the Federal Republic of Germany. Key design parameters for these ractors are compared with the design parameters planned for follow-on commercial-scale HTGRs. The development of HTGR technology has been enhanced by numerous cooperative agreements over the years, involving both government-sponsored national laboratories and industrial participants. Current bilateral cooperative agreements are described. A relatively new component in the HTGR international cooperation is that of multinational industrial alliances focused on supplying commercial-scale HTGR power plants. Current industrial cooperative agreements are briefly discussed

    In mature fruit trees, internal recycling is an important source of N for the growth of new wood, leaves and fruits. Using 15 N-depleted fertilizer, i.e. 14 N-enriched, N-uptake efficiency and the magnitude of internal N cycling were studied in mature walnut trees. Two kg of 14 N-labelled ammonium sulfate N were applied per tree, and compartmentation of N was followed over a period of 6 years by analyzing catkins, pistillate flowers, leaves and fruits each year for total N content and isotopic composition. Subsequently, two of the six labelled trees were excavated and analyzed for labelled-N content. The data indicate that mature walnut uses most of the N accumulated from soil and fertilizer for storage purposes, to be remobilized for new growth within 2 years, and about half of the total-N pool in a mature tree is present as non-structural compounds, available for recycling.

    Full Text Available Agricultural land is decreasing day by day due to erosion, environmental pollution, unconscious irrigation and fertilization. On the other hand, it is necessary to increase agricultural production in order to meet the needs of the developing industry as well as the nutritional needs of the growing population. In the recent years, nano fertilizers have begun to be produced to obtain the highest amount and quality of production from the unit area. Previous research shows that nano fertilizers cause an increase in the use efficiency of plant nutrients, reduce soil toxicity, minimize the potential adverse effects of excessive chemical fertilizer use, and reduce fertilizer application frequency. Nano fertilizers are important in agriculture to increase crop yield and nutrient use efficiency, and to reduce excessive use ofchemical fertilizers. The most important properties of these fertilizers are that they contain one or more of macro and micronutrients, they can be applied frequently in small amounts and are environmentally friendly. However, when applied at high doses, they exhibit decreasing effects on plant growth and crop yields, similar to chemical fertilizers. In this review, the definition, importan ce, and classification of nano fertilizers, their application in plant production, advantages and disadvantages and the results obtained in this field were discussed.

    A field experiment with 15 N isotope tracing micro-plots was carried out to study the effects of basal N fertilizer application time (15 d, 30 d before the transplanting) of flue-cured tobacco (FCT) seedlings and nitrogen fertilization (with N and without N) on growth and development, nicotine concentrations and sources of nicotine N of FCT in Laowan (N 31 degree 27', E 111 degree 14', 1 130 m above sea level), a main tobacco production area of Xiangfan city, Hubei province. The results showed that both dry matter accumulation and nicotine concentrations of different parts of FCT increased with growing of plants. The concentrations of nicotine decreased with the ascending of leaf position before topping period, but just opposite after the removal of apex. The proportion of nicotine N from fertilizer to total nicotine N decreased with growing of FCT plants and the rising of leaf position. Applying N fertilizer significantly increased dry matter accumulation of shoot and the nicotine concentrations of different poisional tobacco leaves by 2.1-2.7 fold and 0.1-0.7 fold respectively. Compared with the basal fertilization time 15 d before transplanting, applying basal fertilizer 30 d before transplanting increased the dry matter accumulation and nicotine concentrations of flue-cured tobacco by 2.2%-8.0% and 6.3%-18.5% respectively. There was no significant effects of basal N fertilization time on the proportion of nicotine-N from fertilizer in organs of FCT plants at mature stage. These results suggested that properly putting forward the basal N fertilization time before transplanting make for decrease of nicotine concentrations and improvement of quality of FCT leaves, so as to improve its industrial utilities.

    2014-02-01

    Full Text Available Soil is not only an important foundation for agricultural production, but also is the safeguard of human survival. Soil quality is close-ly related with food safety and argo-ecological environment. Soil fertility is the support of modern agricultural development. Multiple disci-plines and specialties are involved in researches of soil cultivating process. Nowadays, the understanding of soil fertility has changed from a-gricultural production to environmental security and resource exploitation, even larger scales to ecological health and global soil change. In this review, the characteristics and inherent link between soil and agriculture were comprehensive expounded from the aspects of long-term fertilization trials, soil cultivation techniques, and modern agriculture development. The challenge and prospect faced in soil science research field were also analyzed. Finally, several suggestions and countermeasures were proposed to the researches of soil science in future.

    Nuclear Energy enters a renaissance era. Several countries consider nuclear as one of their energy resources. For example at the present Vietnam just sign an agreement with Russia for their first nuclear power plants, Malaysia expected that the first nuclear power plant will be operated and commercially available in around the year of 2021. Thailand, Singapore and Indonesia also consider having nuclear power plant in the time frame around 2025. Each country recently tries to prepare their regulatory infrastructure for their first nuclear power plant. The problems are each country doesn't have enough human resource and experience in preparing the nuclear power plant regulations infrastructure. The remains regulations resource is from IAEA which are too general to implement and USNRC which are too detail and difficult to implement for the lack of human resources. Therefore this International Regulatory Development Partnership (IRDP) could be the solutions for the demand of regulatory infrastructure preparations for those countries who's want to emerging nuclear power plant in their country

    An expert system for prediction the impact of nitrogen fertilizer on groundwater pollution potential was established by using CLIPS (NASA's Jonson Space Centre). The knowledge base could be extracted from FAO reports, ministry of agriculture and rural development Malaysia report, established literature and domain expert for preparing an expert system skeleton. An expert system was used to correlate the availability of nitrogen fertilizer with the vulnerability of groundwater to pollution in Peninsula Malaysia and to identify potential groundwater quality problems. An n-fertilizer groundwater pollution potential index produced b using the vulnerability of groundwater to pollution yields a more accurate screening toll for identifying potential pollution problems than by considering vulnerability alone. An expert system can predict the groundwater pollution potential under several conditions of agricultural activities and existing environments. (authors)

    2011-10-01

    Stamen development is governed by a conserved genetic pathway, within which the role of hormones has been the subject of considerable recent research. Our understanding of the involvement of gibberellin (GA) signalling in this developmental process is further advanced than for the other phytohormones, and here we review recent experimental results in rice (Oryza sativa) and Arabidopsis (Arabidopsis thaliana) that have provided insight into the timing and mechanisms of GA regulation of stamen development, identifying the tapetum and developing pollen as major targets. GA signalling governs both tapetum secretory functions and entry into programmed cell death via the GAMYB class of transcription factor, the targets of which integrate with the established genetic framework for the regulation of tapetum function at multiple hierarchical levels.

    2014-01-15

    Intracytoplasmic sperm injection (ICSI) technology in birds has been hampered due to opacity of oocyte. We developed ICSI-assisted fertilization and gene transfer in quail. This paper reviews recent advances of our ICSI experiments. The oocyte retrieved from the oviduct and a quail sperm was injected into the oocyte under a stereomicroscope. The oocyte was cultured for 24h at 41°C under 5% CO2 in air. The fertilization and development was assessed by microscopic observation. The fertility rate ranged 12-18% and development varied from stage II to V in trials. To improve the fertility rate, phospholipase C (PLC) zeta was injected with a sperm. It was increased to 37-50%. Furthermore, injection of inositol trisphosphate increased to over 85%. Quail oocyte can be fertilized with chicken sperm and so can testicular elongated spermatid. To extend embryonic development, chicken eggshell was used as a surrogate culture at 37°C after the 24h incubation at 41°C under 5% CO2 in air. It survived up to 2days thereafter. Finally, gene transfer was attempted in quail egg. The sperm membrane was disrupted with Triton X-100 (TX-100) and was injected with PLCzeta cRNA and enhanced green fluorescent protein (EGFP) gene in oocyte. The GFP expression was evaluated at 24h incubation at 41°C under 5% CO2 in air in the embryos. While the expression was not detected in the control oocytes, the experimental treatment induced blastoderm development (44%) of the oocytes and 86% of blastoderm showed fluorescent emission. In addition, PCR analysis detected EGFP fragments in 50% of GFP-expressing blastoderm. Our ICSI method may be the first step toward the production of transgenic birds. Copyright © 2013 Elsevier Inc.

    Addressing current and future food security is not just a matter of producing more food globally. Agricultural productivity must increase where food is most needed, and where both rural and urban populations are expected to increase the fastest in the near future. This is the situation in most of sub-Saharan Africa and in several other regions of Latin America, Asia and the Pacific. There are some common denominators to these regions. In the first place, the inability of the majority of farmers to access and/or to afford agricultural inputs. Second, the severity with which climate change impacts on some of these regions. Third, the extent of soil degradation, which is estimated at 25% of the arable land in the world. And finally, the fact that some of these regions are hosting valuable biodiversity and/or delivering ecosystem services of global or regional importance, which often leads to competing claims between the local and international communities. It has been repeatedly shown that the technologies of industrial agriculture as practiced in developed regions are ineffective at sustaining soil productivity in the context of smallholder family agriculture. Restoring soil productivity and ecosystem functions in these contexts requires new ways of managing soil fertility. These include: (i) innovative forms of 'precision' agriculture that consider the diversity, heterogeneity and dynamics of smallholder farming systems; (ii) a systems approach to nutrient acquisition and management; (iii) agroecological strategies for the restoration of degraded soils and the maintenance of soil physical properties; and (iv) to capitalize on the recent and growing understanding on soil trophic networks to increase nutrient and water use efficiency. I will provide examples on advances in these fronts, and discuss the challenges ahead their broad implementation by farmers in developing regions.

  19. Rapamycin Influences the Efficiency of Fertilization and Development in the Mouse: A Role for Autophagic Activation

    Directory of Open Access Journals (Sweden)

    Geun-Kyung Lee

    2016-08-01

    Full Text Available The mammalian target of rapamycin (mTOR regulates cellular processes such as cell growth, metabolism, transcription, translation, and autophagy. Rapamycin is a selective inhibitor of mTOR, and induces autophagy in various systems. Autophagy contributes to clearance and recycling of macromolecules and organelles in response to stress. We previously reported that vitrified-warmed mouse oocytes show acute increases in autophagy during warming, and suggested that it is a natural response to cold stress. In this follow-up study, we examined whether the modulation of autophagy influences survival, fertilization, and developmental rates of vitrified-warmed mouse oocytes. We used rapamycin to enhance autophagy in metaphase II (MII oocytes before and after vitrification. The oocytes were then subjected to in vitro fertilization (IVF. The fertilization and developmental rates of vitrified-warmed oocytes after rapamycin treatment were significantly lower than those for control groups. Modulation of autophagy with rapamycin treatment shows that rapamycin-induced autophagy exerts a negative influence on fertilization and development of vitrified-warmed oocytes.

  20. Effects of Simulated Mobile Phone Electromagnetic Radiation on Fertilization and Embryo Development.

    This study investigated the effects of 935-MHz electromagnetic radiation (ER) on fertilization and subsequent embryonic development in mice. Ovulating mice were irradiated at three ER intensities for 4 h/day (d) or 2 h/d for three consecutive days; the ova were then harvested for in vitro fertilization to observe the 6-h fertilization rate (6-FR), 72-h morula rate (72-MR), and 110-h blastula rate (110-BR). Compared with the control group, the 6-FR, 72-MR, and 110-BR were decreased in the low ER intensity group, but the differences were not significant; in the mid- and high-intensity ER groups, 72-MR and 110-BR in the 4 h/d and 2 h/d subgroups were decreased, showing significant differences compared with the control group. Moreover, the comparison between 4 h/d and 2 h/d subgroups showed significant differences. Mid- and high-intensity ER at 935 MHz can reduce the fertilization rate in mice, and reduce the blastulation rate, thus reducing the possibility of embryo implantation.

    To determine the effects of sildenafil citrate, a cyclic monophosphate-specific type 5 phosphodiesterase inhibitor known to affect sperm function, on fertilization and early embryo cleavage. This acute mammal study included male and female mice assigned randomly, the females sacrificed after mating and their oocytes/embryos evaluated at four time periods after treatment. Academic research environment. Male and female CBAB(6) mice. Female mice were injected intraperitoneally with 5 IU gonadotropin (hCG) to stimulate follicular growth and induce ovulation. They were each caged with a male that had been gavaged with sildenafil citrate (0.06 mg/0.05 mL) and allowed to mate. After 12, 36, 60, and 84 h, females were killed, their oviducts were dissected out, and retrieved embryos were assessed for blastomere number and quality. Fertilization rates and numbers of embryos were evaluated after treatment. Fertilization rates (day 1) were markedly reduced (-33%) in matings where the male had taken sildenafil citrate. Over days 2-4, the numbers of embryos developing in the treated group were significantly fewer than in the control group. There was also a trend for impaired cleavage rates within those embryos, although this did not reach significance. The impairments to fertility caused by sildenafil citrate have important implications for infertility centers and for couples who are using this drug precoitally while attempting to conceive.

  2. Impact of mineral fertilizers on common winter barley (Hordeum vulgare L. agrophytocenosis development

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available In 2011 to 2013 a study was completed for the impact of varying rates of fertilizing onto the indices of productivity for barley agrophytocenosis of Helios and Commandor, in particular, such its components as a number of productive stems, number of seeds per ear, potential biological activity of ear and photosynthetic apparatus. It is found that the level of spring barley agrophytocenosis productivity is subject both to varietal peculiarities and the rate of mineral fertilizer application. When applying N 60P 60K 60 і N 90P 90K 90 the highest potential and biological productivity of Helios and Commandor was recorder as compared against the control. Impact of varying application rates for fertilizers onto the components of ear biological productivity has been scrutinized. The qualitative composition of ear is a clear expression of variety phenotype and identifies the level of biological yield for spring barley. Application of N 60 P 60 K 60 і N 90 P 90 K 90 mineral fertilizers fairly increased the average leaf surface, photosynthetic lead capacity of varieties in 2 to 2.5 times, as well as FAR efficiency coefficient in 1.5 to 2.0 times as against control that thus contributed to the development of highest biological yield of Helios variety phytomass at the level of 14.9 to 15.0, grain – 7.8 to 8.0 ton per ha and, respectively, 12.7 and 7.5 tons per ha for Comandor variety.

  3. GPR56 is essential for testis development and male fertility in mice.

    2010-12-01

    Testis development is critical for male fertility and continuation of the mammalian species. Essential structural components of testes are seminiferous tubules, which are lined by Sertoli cells and provide nutrients and physical protection for the maturation of sperm. Seminiferous tubule formation is initiated in embryos as testis cords and relies on their remodeling for maturation during development. Recently, three-dimensional image analyses showed that testis cords in different parts of embryonic gonads undergo distinct remodeling processes. How this asymmetric remodeling is regulated has not been investigated. We report here that the absence of an adhesion G protein-coupled receptor, GPR56, leads to partial disruption of seminiferous tubules and reduced fertility in male mice. The defects appear to originate asymmetrically in embryonic gonads, but subsequent to the initial establishment of testis cords, suggesting that GPR56 might act to establish a spatial and/or temporal cue for asymmetric cord remodeling during male gonad development. © 2010 Wiley-Liss, Inc.

  4. Quantitative estimates of uptake and internal cycling of {sup 15}N-depleted fertilizer in mature walnut trees

    In mature fruit trees, internal recycling is an important source of N for the growth of new wood, leaves and fruits. Using {sup 15}N-depleted fertilizer, i.e. {sup 14}N-enriched, N-uptake efficiency and the magnitude of internal N cycling were studied in mature walnut trees. Two kg of {sup 14}N-labelled ammonium sulfate N were applied per tree, and compartmentation of N was followed over a period of 6 years by analyzing catkins, pistillate flowers, leaves and fruits each year for total N content and isotopic composition. Subsequently, two of the six labelled trees were excavated and analyzed for labelled-N content. The data indicate that mature walnut uses most of the N accumulated from soil and fertilizer for storage purposes, to be remobilized for new growth within 2 years, and about half of the total-N pool in a mature tree is present as non-structural compounds, available for recycling.

    To improve survivors' awareness and knowledge of fertility preservation counseling and treatment options, this study engaged survivors and providers to design, develop, and field-test Pathways: a fertility preservation patient decision aid website for young women with cancer©. Using an adapted user-centered design process, our stakeholder advisory group and research team designed and optimized the Pathways patient decision aid website through four iterative cycles of review and revision with clinicians (n = 21) and survivors (n = 14). Field-testing (n = 20 survivors) assessed post-decision aid scores on the Fertility Preservation Knowledge Scale, feasibility of assessing women's decision-making values while using the website, and website usability/acceptability ratings. Iterative stakeholder engagement optimized the Pathways decision aid website to meet survivors' and providers' needs, including providing patient-friendly information and novel features such as interactive value clarification exercises, testimonials that model shared decision making, financial/referral resources, and a printable personal summary. Survivors scored an average of 8.2 out of 13 (SD 1.6) on the Fertility Preservation Knowledge Scale. They rated genetic screening and having a biological child as strong factors in their decision-making, and 71% indicated a preference for egg freezing. Most women (> 85%) rated Pathways favorably, and all women (100%) said they would recommend it to other women. The Pathways decision aid is a usable and acceptable tool to help women learn about fertility preservation. The Pathways decision aid may help women make well-informed values-based decisions and prevent future infertility-related distress.

    To investigate fertility outcome in individuals with different forms of disorders of sex development (DSD), if assisted reproductive technology (ART) was used, and the patients' satisfaction with the information they had received. A cross-sectional multicenter study, dsd-LIFE. Not applicable. A total of 1,040 patients aged ≥16 years with different DSD diagnoses participated. A web-based questionnaire was filled out by all participants. The participants could chose to take part in somatic investigations including ultrasonography. Information on partner, number of children, ART, adoption and step-children, general health, presence of gonads and uterus, current education and economic situation, received information on fertility issues, and satisfaction with the information, was collected. In the total cohort, mean age 32 years, 33% lived with a partner, but only 14% reported having at least one child including 7% with ART, 4% adopted. Only 3.5% of the total cohort had been able to reproduce without ART, most frequently women with congenital adrenal hyperplasia, and only 0.7% of participants with other diagnoses. Of the participants, 72% had received information on fertility, but 17% were not satisfied with the information. Fertility outcome is significantly reduced in all types of DSD; however, fertility potential should be assessed individually. The satisfaction with how fertility problems have been discussed can be improved. The care of patients with DSD is complex, should be individualized, and new treatment possibilities incorporated. A close collaboration in multidisciplinary teams is therefore essential to improve the situation for individuals with DSD. Copyright © 2017 American Society for Reproductive Medicine.

  3. Fertility treatment: long-term growth and mental development of the children.

    Science.gov (United States)

    Bay, Bjørn

    2014-10-01

    Fertility treatment has been associated with obstetrical and perinatal complications. It is, however, uncertain whether fertility treatment or parental subfertility is associated with long-term development of the children. We aimed to assess the growth and mental health of children and adolescents conceived after fertility treatment compared to spontaneously conceived controls. First, we evaluated all previous studies comparing neurodevelopmental outcomes between children conceived after fertility treatment and spontaneous conceived controls. The systematic review clarified methodological limitations in the existing literature on the long-term development of children conceived after medical assisted reproduction. Although several studies had been published, large, well-controlled studies with long-term follow-up and thorough statistical adjustments were still few. Second, we evaluated the children's mental health by assessing the risk of mental disorders. We studied a population of 555,828 children conceived after spontaneous conception and 33,139 children conceived after fertility treatment with follow-up in 2012 when the children were 8-17 years old. The absolute risk and hazard ratio of overall and specific mental disorders were estimated while adjusting for potential confounding variables. Further, we estimated the association between subtypes of procedures, hormonal treatment, gamete types and cause of infertility on the one hand and the risk of mental disorders on the other. Children conceived after ovulation induction had a low, but significantly increased risks of autism spectrum disorders, hyperkinetic disorders, conduct, emotional, or social disorders, and tic disorders. Children conceived after IVF or ICSI showed no increased risk, except for a small risk of tic disorders. There was no risk systematically related to any specific type of hormone drug treatment. Thus, the increased risks may rely on residual confounding such as unknown parental factors

    This paper studies the perspectives of breeder reactors development. The near term context has led some experts to the conclusion that breeder reactor technology is too far ahead of its time. Some have compared breeders to the supersonic airplane, Concorde: good technical performance but failure in its economic dimensions. In this paper, the author points out the major shortcomings of such an assessment which may be valid in the short time. However, with a short-term market-dominated perspective that uses an 8% discount rate, one can neglect every thing that is going to happen in 50 years. 6 refs., 11 figs

  9. International financial markets and development

    Directory of Open Access Journals (Sweden)

    2009-11-01

    Full Text Available The current financial crisis has not come about by chance. It is the result of a system that has emerged over the last 30 years and which Keynes may well have called the ‘casino economy’. The dominance of finance over real economy characterises the financial crisis, while finance itself is dominated by the all-encompassing target of maximum profit at all times. Other aims of economic activity such as job creation, social welfare and development have fallen by the wayside. In response, new actors are surfacing, e.g. the institutional investor (hedge funds, private equity funds, etc., while new instruments are leading to highly leveraged and destabilising derivatives. The casino system has been promoted by governments and intergovernmental institutions to liberalise and deregulate financial markets. Although developing countries have not participated in the casino system, they have been suffering most from the spill-over into the real economy. The main lesson learnt is that the casino has to be closed.

    This article reports on the implications and benefits of Internet technology among women from developing countries. Cyberfeminism is the practice of feminism in cyberspace. Feminists believe that women should take control and augment Internet technologies to empower themselves. Learning to use the computers, getting "connected," and surfing the Internet are encouraged among all women with the aim of advancing feminist causes and empowering women. The Internet has been observed to cause radical changes in the way business and social activities are conducted. A description of how two women have engaged in cyberfeminism and worked in development and technology programs is included. One contributor, Annapurna Mamipudi, is involved in a non-governmental organization working with traditional handloom weavers in India Another contributor is Radhika Gajjala, who works in academia and creates on-line "discussion lists" and Web sites from her North American geographical location. Her job is to create spaces that provide opportunities for dialogue and collaboration among women with Internet access all over the world.

  11. US agency for international development

    Pumfrey, R.

    1997-12-01

    The author addresses the following questions in his presentation: what is USAID; where does the money go and who makes the decisions; where does USAID fund energy programs, and especially renewable energy; who are their `partners`; what is the approach to renewable energy; what in summary, has USAID funded that is relevant to village power. USAID is the foreign aid agency of the US Government. Approximately 75 countries receive regular assistance. The fiscal year 97 budget for the agency is approximately $5.8 billion. About half of the total budget goes to Israel, Egypt, and the countries of the former Soviet Union. These budgeting decisions are geopolitical. Congress earmarks total budgets for a few sectors or subjects, such as family planning. The goal of USAID`s renewable energy programs is simple: They are interested in accelerating the market penetration of commercial technologies. They do not engage in technology R&D. Developing countries have energy needs now, and commercial technologies are available now. USAID has taken note of the interest taken by subsidiaries of US utilities in the past couple of years in bringing their expertise and resources to bear on meeting the challenge of rural energy needs in developing countries. They believe that the entry into the market of these players could be one of the most important catalysts for making the rural energy revolution happen.

  12. RESTORATION OF FERTILITY IN A MAN WITH AZOOSPERMIA DEVELOPED IN RESPONSE TO TREATMENT WITH TESTOSTERONE GEL (A CASE REPORT

    Directory of Open Access Journals (Sweden)

    I. A. Korneev

    2017-01-01

    Full Text Available Testosterone replacement therapy (TRT allows to combat the symptoms of age-related androgen deficiency (AAD; however, it may have side effects, including the reduction in sperm count and even complete cessation of spermatogenesis and development of azoospermia. The fertility may not be restored even within 18 month after treatment completion. Russian researcher explored the impact of TRT with gel on the ejaculate parameters in men with hypogonadism and observed no negative effects on spermatogenesis within 3 months after treatment initiation. We describe a clinical case of reversible azoospermia induced by a relatively short course of TRT with gel. Fertilizing capacity of sperm was finally restored, which was confirmed by a clinical pregnancy obtained by in vitro fertilization. Physicians prescribing TRT should inform their patients that such treatment is contraindicated to those men who would like to preserve their fertility and explain that the restoration of fertility will take some time after treatment completion.

  18. Effects of simulated weightlessness on meiosis. Fertilization, and early development in mice

    Wolgemuth, D. J.

    1986-01-01

    The initial goal was to construct a clinostat which could support mammalian cell culture. The clinostat was selected as a means by which to simulate microgravity conditions within the laboratory, by constant re-orientation of cells with respect to the gravity vector. The effects of this simulated microgravity on in-vitro meiotic maturation of oocytes, using mouse as the model system, was investigated. The effects of clinostat rotation on fertilization in-vitro was then examined. Specific endpoints included examining the timely appearance of male and female pronuclei (indicating fertilization) and the efficiency of extrusion of the second polar body. Particular attention was paid to detecting anomalies of fertilization, including parthenogenetic activation and multiple pronuclei. Finally, for the preliminary studies on mouse embryogenesis, a key feature of the clinostat was modified, that of the position of the cells during rotation. A means was found to immobilize the cells during the clinostat reotation, permitting the cells to remain at the axis of rotation yet not interfering with cellular development.

    Full Text Available Introduction: Tamoxifen is steroidal drug, which mainly treats breast cancer and also used to stimulate ovulation. The purpose of the present study was the evaluation of sperm parameters and fertility of mice whose mothers had received tamoxifen during pregnancy. Methods: In this study, 30 female and 15 male mice of NMRI were selected for mating. After mating female mice were randomly divided into two groups, the first group (control and second group (experimental. All of which contained 15 mice. From the day 13th day of pregnancy, experimental group has received tamoxifen with the dosage of 5 mg/kg for 7 days. After childbirth of the mated mice, male infants were selected. After reaching the age of puberty (6-8Weeks, adult mice were sacrificed by the cervical dislocation. After take sperm, sperm parameters (count, normality and motility, and sperm fertility was performed. In this study SPSS software and statistical t-test was used (p <0.001. Results: Studies showed that sperm parameters and sperm fertilization were significantly different. The number of sperm in the control group was 83.50±28.20 million, and in the experimental group was 60±14.14 million. There was a decrease in average sperm count in the experimental group compared with the control group (p <0.001. Our findings from in vitro fertilization culture media showed that embryos formation and oocyte disruption between control and experimental groups significantly different (p <0.001. Conclusion: The results showed that tamoxifen exposure during development can cause histological changes in the seminiferous tubules, which can lead to infertility.

    Full Text Available There was analyzed the effect of selected essential oils (orange, lemon, vanilla, linden blossom, thyme, geranium and tea oils on the development and fertility of the most dangerous cereal grain storage pest, grain weevil. Based on the results obtained, it was observed that a strong effect limiting the population of grain weevil was found for vanilla and orange oils. In the experiment combinations which involved essential oils, there was observed a prolonged pest development cycle and a higher mortality of maternal individuals than in the other tests. On the other hand, the lowest fecundity rate was recorded in the combination in which thyme oil was tested.

    Schatten, Heide

    1996-01-01

    The overall objectives of this project are to explore the role of microgravity during fertilization, early development, cytoskeletal organization, and skeletal calcium deposition in a model development system: the sea urchin eggs and embryos. While pursuing these objectives, we have also helped to develop, test, and fly the Aquatic Research Facility (ARF) system. Cells were fixed at preselected time points to preserve the structures and organelles of interest with regards to cell biology events during development. The protocols used for the analysis of the results had been developed during the earlier part of this research and were applied for post-flight analysis using light and (immuno)fluorescence microscopy, scanning electron microscopy, and transmission electron microscopy. The structures of interest are: microtubules during fertilization, cell division, and cilia movement; microfilaments during cell surface restructuring and cell division; centrosomes and centrioles during cell division, cell differentiation, and cilia formation and movement; membranes, Golgi, endoplasmic reticulum, mitochondria, and chromosomes at all stages of development; and calcium deposits during spicule formation in late-stage embryos. In addition to further explore aspects important or living in space, several aspects of this research are also aimed at understanding diseases that affect humans on Earth which may be accelerated in space.

    The objective of this study was to improve the ability of sporulation production of Trichoderma guizhouense NJAU4742 under solid state fermentation by using rice straw and amino acids as resources, and the fermentation products were used as inoculants of the organic fertilizers adding with different ratios of amino acids solution to develop a new type of biological organic fertilizer. The results indicated that the optimal condition for sporulation by T. guizhouense NJAU4742 was soaking in 30 times diluted amino acid solution for one whole night, with initial pH 3.5, 75% of moisture content and 30% of corn powder, under which the sporulation reached to 2.40×10 10 CFU·g -1 . The fermentation products were inoculated at 2% into the mature organic fertilizer containing 20% of amino acids solution, and the sporulation and IAA content were 6.40×10 9 CFU·g -1 and 38.66 mg·kg -1 , which were 1142.30 and 1.42 times higher than that of CK after 7 days, respectively. Pot experiment showed that biological organic fertilizer could significantly promote the growth of tomato, and the height of the tomato increased by 98.8% and 23.8%, respectively, compared with CK. The stem diameters of AT (amino acids + mature organic fertilizer + T. guizhouense NJAU4742) and AA (amino acids + mature organic fertilizer) were increased by 58.9% and 10.3%, respectively, compared with CK. As for the chlorophyll, leaf length and leaf width, the values also increased significantly. The highest spore content was obtained by using amino acids and rice straw as substrates under solid state fermentation (SSF), which overcame the difficulties of producing new type of biological organic fertilizer during the large scale industrial production. Biological organic fertilizer and amino acids organic fertilizer could significantly promote the growth of tomato compared with the chemical fertilizer, and had a good application prospect in intensive agriculture.

    Internal radiation dose assessment involves biokinetic models, the corresponding parameters, measured data, and many assumptions. Every component considered in the internal dose assessment has its own uncertainty, which is propagated in the intake activity and internal dose estimates. For research or scientific purposes, and for retrospective dose reconstruction for accident scenarios occurring in workplaces having a large quantity of unsealed radionuclides, such as nuclear power plants, nuclear fuel cycle facilities, and facilities in which nuclear medicine is practiced, a quantitative uncertainty assessment of the internal dose is often required. However, no calculation tools or computer codes that incorporate all the relevant processes and their corresponding uncertainties, i.e., from the measured data to the committed dose, are available. Thus, the objective of the present study is to develop an integrated probabilistic internal-dose-assessment computer code. First, the uncertainty components in internal dosimetry are identified, and quantitative uncertainty data are collected. Then, an uncertainty database is established for each component. In order to propagate these uncertainties in an internal dose assessment, a probabilistic internal-dose-assessment system that employs the Bayesian and Monte Carlo methods. Based on the developed system, we developed a probabilistic internal-dose-assessment code by using MATLAB so as to estimate the dose distributions from the measured data with uncertainty. Using the developed code, we calculated the internal dose distribution and statistical values (e.g. the 2.5{sup th}, 5{sup th}, median, 95{sup th}, and 97.5{sup th} percentiles) for three sample scenarios. On the basis of the distributions, we performed a sensitivity analysis to determine the influence of each component on the resulting dose in order to identify the major component of the uncertainty in a bioassay. The results of this study can be applied to various

  8. Understanding the development of international environmental agreements

    DEFF Research Database (Denmark)

    Stærdahl, Jens

    There are many different theoretical schools concerned with how international regimes develop, and each supplies its own interpretation focusing on one or a few aspects of the process. Such ‘one shot’ explanations may be fruitful for scientific debate, but less useful as conceptual frameworks...... for practitioners and planners manoeuvring in a complex world. On the basis of a review of selected theories of international and environmental regulation, this article initiates the development of a conceptual framework for understanding the development of internationalenvironmental agreements. The point...... of departure for developing the model is the actor-structure debate within social science and theory of international relations. Based on critical realism, a framework is developed specifying the relation between collective action problem situations and negotiation situations. It is argued that the main...

  9. Diversity of arbuscular mycorrhizal fungi in grassland spontaneously developed on area polluted by a fertilizer plant

    International Nuclear Information System (INIS)

    Renker, C.; Blanke, V.; Buscot, F.

    2005-01-01

    Mycorrhizal colonization and diversity of arbuscular mycorrhizal fungi (AMF) were analyzed in a calcareous grassland with residual phosphate contamination 10 years after the closure of a pollutant fertilizer plant in Thuringia (Germany). AMF were detected in 21 of 22 plant species analyzed. Mean mycorrhization levels reached up to 74.5% root length colonized. AMF diversity was analyzed based on 104 sequences of the internal transcribed spacer (ITS) of the ribosomal DNA. Phylogenetic analyses revealed a total of 6 species all belonging to the genus Glomus. There was no overlap between species detected as active mycorrhizas on roots (2 taxa) or as spores (4 taxa). Compared to the regional context, the diversity of AMF at our field site was reduced, which may reflect a residual disturbance effect. However, none of the detected species was exclusive to the polluted site as they are commonly found in the region. - Almost all plant species were mycorrhizal

  10. An Agent-Based Dynamic Model of Politics, Fertility and Economic Development

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available In the political economy of development, government policy choices at a single point in time can dramatically affect a country's development path by impacting fertility, economic and political decisions across generations. Combining system dynamics and agent-based modeling approaches in a complex adaptive system, a simulation framework of the Politics of Fertility and Economic Development (POFED is formalized to understand the relationship between politics, economic, and demography change at both macro and micro levels. First, a new political capacity measurement is used; and the system dynamics model is validated with the latest data. Second, the endogenous attributes are fused with non-cooperative game theory in an agent-based framework to simulate the interactive political economic dynamics of individual intra-societal transactions. Finally, macro and micro levels are connected with policy levers of political capacity and political instability by merging system dynamics and agent-based components. This paper also explores the agent-based model's behavioral dynamics via simulation methods to identify paths towards economic development and political stability. This model demonstrates micro level human agency can act, react and interact, thus driving macro level dynamics, while macro structures provide political, social and economic environments that constrain or incentivize micro level human behavior.

  6. ECONOMIC DEVELOPMENT THROUGH AID OR INTERNATIONAL TRADE

    Directory of Open Access Journals (Sweden)

    Ana Mihei

    2010-12-01

    Full Text Available Economic development is the supreme goal of modern civilization. This phenomenon is seen not just in terms of growth, but rather as an overall improvement in living standards. Economic development is a national goal, but also an objective of international economic bodies. Talks about development are held in the context of the opposition between developed countries and developing countries.In this article, we discuss whether development aid that originates from industrialized states supports sustainable economic rise of the countries lagging behind and whether it is preferable to let market operate freely, through the liberalization of international trade. Our conclusion is that economic development through the promotion of free trade would be achieved faster and more efficiently, based on net gains from trade and the pride of the peoples who would have won by themselves their daily bread and a place in the global market.

  7. Injurious Effects of Curcumin on Maturation of Mouse Oocytes, Fertilization and Fetal Development via Apoptosis

    Directory of Open Access Journals (Sweden)

    Wen-Hsiung Chan

    2012-04-01

    Full Text Available Curcumin, a common dietary pigment and spice, is a hydrophobic polyphenol derived from the rhizome of the herb Curcuma longa. Previously, we reported a cytotoxic effect of curcumin on mouse embryonic stem cells and blastocysts and its association with defects in subsequent development. In the present study, we further investigated the effects of curcumin on oocyte maturation and subsequent pre- and post-implantation development, both in vitro and in vivo. Notably, curcumin induced a significant reduction in the rate of oocyte maturation, fertilization, and in vitro embryonic development. Treatment of oocytes with curcumin during in vitro maturation (IVM led to increased resorption of postimplantation embryos and decreased fetal weight. Experiments with an in vivo mouse model disclosed that consumption of drinking water containing 40 μM curcumin led to decreased oocyte maturation and in vitro fertilization as well as early embryonic developmental injury. Finally, pretreatment with a caspase-3-specific inhibitor effectively prevented curcumin-triggered injury effects, suggesting that embryo impairment by curcumin occurs mainly via a caspase-dependent apoptotic process.

  8. [International conference on population and development in Cairo].

    The UN Conference on Population and Development was held in Cairo in September 1994, and dealt with a range of sensitive issues that were eventually recorded in an action program. In addition, a sort of shadow conference was also held by various organizations. The precedents of this conference were the conferences held in Bucharest in 1974, which stressed the world crisis and population explosion, and in Mexico in 1984, where the first signs of the slackening of population growth induced less emphasis on family planning programs and more on the status of women. At Cairo again a crisis atmosphere reigned because rapid population growth has not been followed by rapid development. Birth control discussions also focused on ethical and religious norms, human rights, and emancipation problems. Most of all, the sustainability of development programs was stressed. Global decline of mortality combined with a continuing high birth rate has resulted in a population growth of 3% or more. In the course of 40 years the growth was 46% in industrialized countries as compared to 161% in the poorest lands. The total world population has reached 5 billion, of which only 20% live industrial countries. The influence of the AIDS epidemic on the demographic figures is not likely to be as much as anticipated a few years ago. Other problems are demographic aging, population decline (a below replacement fertility rate in Japan, Spain, and Italy), and uncontrolled internal and international migration (refugees in developing countries and flight to major cities). In the next 30 years almost two-thirds of the population of developing countries will be living in shabby, sprawling megacities. In 1989, in preparation for the Cairo conference, an international forum was held in Amsterdam on population. It dealt with the reproductive rights of women, the negative impact of structural readjustment programs on family planning, and the priority of women's education.

  9. Long-term effects of prenatal X ray on development and fertility of human females

    1976-01-01

    This continuing epidemiologic study investigates possible effects of X-ray exposure during foetal life on the subsequent development and fertility of human females and on their offspring. The study population comprises 1458 females exposed in utero to maternal diagnostic X ray such as pelvimetry, and 1458 unexposed controls matched by hospital of birth, parity, race and birthdate (1947-1952). Phase I of the study showed a 10-15% increase in fertility in young exposed women, based on ascertainment of live births and foetal deaths registered in Baltimore City. This statistically significant difference (p=0.011) remained after adjustment for differences between exposed and control women in economic, social and medical factors. Phase II of the study, a direct follow-up of exposed control pairs of women now aged 22-28, continues to show more total pregnancies among exposed women. Exposed-in-utero women had 15% more total pregnancies than controls in 1960-1969, and 7% more in 1970-1975. Exposed and control women are similar in number of siblings, number of children wanted, contraceptive use, and frequency of therapeutic abortion. Other findings suggest possible exposed-control differences in growth, development and behaviour. Exposed women have completed fewer grades of school, have poorer general health, more menstrual problems, more of certain diseases and accidents, and are heavier for height than controls. (author)

    2015-01-01

    Full Text Available The article analyzes the main internal problems of the Shanghai Cooperation Organization. Particular attention is paid to the conflict of interests of the participating countries, as well as identifying obstacles to strengthen the organization and increase its influence in the international arena. The international organizations are created by the states to meet mutual problems in the course of interstate relations requiring regular cooperation mechanism. Given the background of the Organization, it is important to emphasize that the main reason for the establishment of the Shanghai organization was the need for the united front against the strengthening of the region at the turn of centuries against dangerous trends of terrorism, extremism, separatism, the growth of organized crime. Despite the conflict of interests and the internal and external development challenges thirteen-year history of evolution of the SCO, to some extent proves its effectiveness, moreover, there are the preconditions for its consistent transition to a more comprehensive organization.

    The increasing number of people living with multiple chronic conditions in addition to an index condition has become an international healthcare priority. Health education curricula have been developed alongside single condition frameworks in health service policy and practice and need redesigning to incorporate optimal management of multiple conditions. Our aims were to evaluate current teaching and learning about comorbidity care amongst the global population of healthcare students from different disciplines and to develop an International Comorbidity Education Framework (ICEF) for incorporating comorbidity concepts into health education. We surveyed nursing, medical and pharmacy students from England, India, Italy and Sweden to evaluate their understanding of comorbidity care. A list of core comorbidity content was constructed by an international group of higher education academics and clinicians from the same disciplines, by searching current curricula and analysing clinical frameworks and the student survey data. This list was used to develop the International Comorbidity Education Framework. The survey sample consisted of 917 students from England (42%), India (48%), Italy (8%) and Sweden (2%). The majority of students across all disciplines said that they lacked knowledge, training and confidence in comorbidity care and were unable to identify specific teaching on comorbidities. All student groups wanted further comorbidity training. The health education institution representatives found no specific references to comorbidity in current health education curricula. Current clinical frameworks were used to develop an agreed list of core comorbidity content and hence an International Comorbidity Education Framework. Based on consultation with academics and clinicians and on student feedback we developed an International Comorbidity Education Framework to promote the integration of comorbidity concepts into current healthcare curricula.

  13. ISO: international standards development for nuclear technology

    International Nuclear Information System (INIS)

    Becker, K.

    1981-01-01

    The importance of internationally recognized standards for nuclear technology and safety is rapidly increasing for technical as well as economical and political reasons such as public acceptance and nuclear technology transfer to developing countries. The need for such standards is also evident because of the large number of nuclear installations sited close to international borders, and the export of nuclear installations from relatively few supplier countries to a large number of user countries. It is the purpose of this report to describe briefly the history, organizational structures and procedures, goals, accomplishments, problems, and future needs of the relevant activities of the International Organization for Standardization (ISO). ISO is composed of the partly governmental, partly non-governmental national standards bodies of 86 countries including China. The work of its Technical Committee (TC) 85 'Nuclear Energy' is mostly concerned with industrial applications, contractual aspects and international communication, for the benefit of both developed and developing countries. It works in close liaison with IAEA, which develops Codes and Guides addressed mainly to the regulatory aspects of nuclear power plants in developing countries. ISO/TC 85 has four sub-committees dealing with: (a) Terminology, Definitions, Units and Symbols (Secretariat USA, four working groups (WGs)); (b) Radiation Protection (Secretariat France, ten WGs); (c) Power Reactor Technology (Secretariat Sweden, nine WGs); (d) Nuclear Fuel Technology (Secretariat F.R. Germany, seven WGs). (author)

  14. "International regime for advancing lunar development"

    Science.gov (United States)

    Beldavs, VZ

    2017-09-01

    A specific concern regarding the Moon Treaty is the provision for sharing the wealth gained from space with developing countries that have not invested and taken risks in making possible space materials utilization. Article 11, par. 7 states "The main purposes of the international regime to be established shall include: (a) The orderly and safe development of the natural resources of the moon; (b) The rational management of those resources; (c) The expansion of opportunities in the use of those resources; (d) An equitable sharing by all States Parties in the benefits derived from those resources, whereby the interests and needs of the developing countries, as well as the efforts of those countries which have contributed either directly or indirectly to the exploration of the moon, shall be given special consideration." Whether the Moon Treaty in its present form or modified to be acceptable to more parties or the Moon Treaty is ignored, the language of Article 11, paragraph 7 can be used to construct an international regime for lunar development that can meet the requirements of commercial business as well as of states that provide support for lunar development as well as developing countries that may have played a modest role in making lunar development possible. This paper will consider options for constructing an international regime for lunar development.

  15. A small population of hypothalamic neurons govern fertility: the critical role of VAX1 in GnRH neuron development and fertility maintenance.

    Science.gov (United States)

    Hoffmann, Hanne M; Mellon, Pamela L

    2016-01-01

    Fertility depends on the correct maturation and function of approximately 800 gonadotropin-releasing hormone (GnRH) neurons in the brain. GnRH neurons are at the apex of the hypothalamic-pituitary-gonadal axis that regulates fertility. In adulthood, GnRH neurons are scattered throughout the anterior hypothalamic area and project to the median eminence, where GnRH is released into the portal vasculature to stimulate release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary. LH and FSH then regulate gonadal steroidogenesis and gametogenesis. Absence of GnRH neurons or inappropriate GnRH release leads to infertility. Despite the critical role of GnRH neurons in fertility, we still have a limited understanding of the genes responsible for proper GnRH neuron development and function in adulthood. GnRH neurons originate in the olfactory placode then migrate into the brain. Homeodomain transcription factors expressed within GnRH neurons or along their migratory path are candidate genes for inherited infertility. Using a combined in vitro and in vivo approach, we have identified Ventral Anterior Homeobox 1 ( Vax1 ) as a novel homeodomain transcription factor responsible for GnRH neuron maturation and fertility. GnRH neuron counts in Vax1 knock-out embryos revealed Vax1 to be required for the presence of GnRH-expressing cells at embryonic day 17.5 (E17.5), but not at E13.5. To localize the effects of Vax1 on fertility, we generated Vax1 flox mice and crossed them with Gnrh cre mice to specifically delete Vax1 within GnRH neurons. GnRH staining in Vax1 flox/flox :GnRH cre mice show a total absence of GnRH expression in the adult. We performed lineage tracing in Vax1 flox/flox :GnRH cre :RosaLacZ mice which proved GnRH neurons to be alive, but incapable of expressing GnRH. The absence of GnRH leads to delayed puberty, hypogonadism and complete infertility in both sexes. Finally, using the immortalized model GnRH neuron cell lines, GN11 and

    Full Text Available Currently, the management of urban waste streams in developing countries is not optimized yet, and in many cases these wastes are disposed untreated in open dumps. This fact causes serious environmental and health problems due to the presence of contaminants and pathogens. Frequently, the use of specific low-cost strategies reduces the total amount of wastes. These strategies are mainly associated to the identification, separate collection and composting of specific organic waste streams, such as vegetable and fruit refuses from food markets and urban gardening activities. Concretely, in the Chimborazo Region (Ecuador, more than 80% of municipal solid waste is dumped into environment due to the lack of an efficient waste management strategy. Therefore, the aim of this study was to develop a demonstration project at field scale in this region to evaluate the feasibility of implanting the composting technology not only for the management of the organic waste fluxes from food market and gardening activities to be scaled-up in other developing regions, but also to obtain an end-product with a commercial value as organic fertilizer. Three co-composting mixtures were prepared using market wastes mixed with pruning of trees and ornamental palms as bulking agents. Two piles were created using different proportions of market waste and prunings of trees and ornamental palms: pile 1 (50:33:17 with a C/N ratio 25; pile 2: (60:30:10 with C/N ratio 24 and pile 3 (75:0:25 with C/N ratio 33, prepared with market waste and prunings of ornamental palm. Throughout the process, the temperature of the mixtures was monitored and organic matter evolution was determined using thermogravimetric and chemical techniques. Additionally, physico-chemical, chemical and agronomic parameters were determined to evaluate compost quality. The results obtained indicated that all the piles showed a suitable development of the composting process, with a significant organic matter

    Jakeline R. de Oliveira

    2016-02-01

    Full Text Available ABSTRACT The cultivation of upland rice (Oryza sativa in Brazil occurs mainly in the Cerrado, a region with adverse weather conditions. The use of silicon in its cultivation becomes important, since this nutrient provides higher rigidity, lower transpiration and higher resistance to dry spells in rice plants. The objective of the present study was to evaluate the effect of silicon fertilization and soil water tensions on upland rice development and yield in a Cerrado Oxisol. A 5 x 5 fractionated factorial with five soil water tensions (0, 15, 30, 45 and 60 kPa and five silicon doses (0, 120, 240, 480 and 960 mg dm-3 was used, which were distributed in a randomized block design, with four replicates. Plant height, number of tillers, number of panicles, number of grains per panicle, numbers of full and empty grains and percentage of empty grains were evaluated. Silicon fertilization promotes increased tillering in rice plants at the dose of 960 mg dm-3. The numbers of tillers and panicles decreased with the application of silicon up to the doses of 460 and 490 mg dm-3, respectively. The increase in soil water tensions reduced plant height and the number of full grains, and increased the percentage of empty grains of upland rice.

    Micromanipulator is a mechanical device used for manipulating miniature objects in the order of micron. It is widely used in In-Vitro Fertilization (IVF) in which sperms will be held in a micro-needle and penetrate to an oocyte for fertilization. IVF needs to be performed by high skill embryologists to control the movement of the needle accurately due to the lack of tactile perception of the user. Haptic device is a device that can transmit and simulate position, velocity and force in order to enhance interaction between the user and system. However, commercially available haptic devices have unnecessary degrees of freedom and limited workspace which are inappropriate for IVF process. This paper focuses on development of a haptic device for using in IVF process. It will be used as a master arm for the master-slave system for IVF process in order to enhance the ability of users to control the micromanipulator. As a result, the embryologist is able to carry out the IVF process more effectively with having tactile perception.

  18. The effects of migrant remittances on population–environment dynamics in migrant origin areas: international migration, fertility, and consumption in highland Guatemala

    Science.gov (United States)

    Lopez-Carr, David

    2010-01-01

    International migration impacts origin regions in many ways. As examples, remittances from distant migrants may alter consumption patterns within sending communities, while exposure to different cultural norms may alter other behaviors. This paper combines these insights to offer a unique lens on migration’s environmental impact. From an environmental perspective, we ask the following question: is the likely rise in consumption brought about by remittances counterbalanced by a reduction in fertility in migrant households following exposure to lower fertility cultures? Based on ethnographic case studies in two western highland Guatemalan communities, we argue that the near-term rise in consumption due to remittances is not counterbalanced by rapid decline in migrant household fertility. However, over time, the environmental cost of consumption may be mitigated at the community level through diffusion of contraception and family planning norms yielding lower family size.

  20. Future fertility for individuals with differences of sex development: Parent attitudes and perspectives about decision-making.

    Johnson, Emilie K; Rosoklija, Ilina; Shurba, Angela; D'Oro, Anthony; Gordon, Elisa J; Chen, Diane; Finlayson, Courtney; Holl, Jane L

    2017-08-01

    Children, adolescents, and young adults (children/youth) with differences/disorders of sex development (DSD) face challenges related to future fertility; this may be due to variations in gonadal development, and, for some, gonadectomy performed to reduce the risk of malignancy. Childhood may be the only time for preservation of biological fertility potential for children/youth who undergo gonadectomy or have early gonadal failure. Fertility-related decision-making for these patients is particularly complicated, due to the need for parental proxy decision-making, potential discordance between gender identity and gonadal type, and uncertain future assisted reproductive technologies. This study aimed to assess: (1) attitudes regarding future fertility, and (2) healthcare needs for fertility-related decision-making among parents of children/youth with DSD. Semi-structured qualitative interviews about future fertility were conducted with parents of children/youth with DSD. Parents who had never discussed fertility with a healthcare provider were excluded. Grounded theory methodology was used to identify emergent themes and patterns. Demographics and clinical characteristics were assessed via survey and medical chart review. Nineteen parents were interviewed (participation rate: 60%, 14 mothers/5 fathers, median patient age at diagnosis 6 months (range 0-192), eight DSD diagnoses). The most common emergent themes are summarized in the Summary Table. Most parents identified fertility as a key concern, both at time of diagnosis and throughout development. Parents expressed difficulty with timing of disclosure about potential infertility to their children. Multiple preferences related to medical decision-making about future fertility and fertility preservation were expressed, including: a desire for step-by-step decision-making, and use of medically vetted information and research to guide decisions. This qualitative study provided new information about the perspectives of

  1. Does Embryo Culture Medium Influence the Health and Development of Children Born after In Vitro Fertilization?

    Full Text Available In animal studies, extensive data revealed the influence of culture medium on embryonic development, foetal growth and the behaviour of offspring. However, this impact has never been investigated in humans. For the first time, we investigated in depth the effects of embryo culture media on health, growth and development of infants conceived by In Vitro Fertilization until the age of 5 years old. This single-centre cohort study was based on an earlier randomized study. During six months, in vitro fertilization attempts (No. 371 were randomized according to two media (Single Step Medium--SSM group or Global medium (Global group. This randomized study was stopped prematurely as significantly lower pregnancy and implantation rates were observed in the SSM group. Singletons (No. 73 conceived in the randomized study were included (42 for Global and 31 for SSM. The medical data for gestational, neonatal and early childhood periods were extracted from medical records and parental interviews (256 variables recorded. The developmental profiles of the children in eight domains (social, self-help, gross motor, fine motor, expressive language, language comprehension, letter knowledge and number knowledge--270 items were compared in relation to the culture medium. The delivery rate was significantly lower in the SSM group than in the Global group (p<0.05. The culture medium had no significant effect on birthweight, risk of malformation (minor and major, growth and the frequency of medical concerns. However, the children of the Global group were less likely than those of the SSM group to show developmental problems (p = 0.002, irrespective of the different domains. In conclusion, our findings showed that the embryo culture medium may have an impact on further development.

    Studies investigating fertility decline in developing countries often adopt measures of determinants of fertility behavior developed based on observations from developed countries, without adapting them to the realities of the study setting. As a result, their findings are usually invalid, anomalous or statistically non-significant. This commentary draws on the research article by Moeeni and colleagues, as an exemplary work which has not adapted measures of two key economic determinants of fertility behavior, namely gender inequality and opportunity costs of childbearing, to the realities of Iran's economy. Measurement adaptations that can improve the study are discussed.

  5. Development of lucerne (Medicago sativa L.) treated with mineral fertilizer and manure at optimal and water deficit conditions.

    Vasileva, V; Kostov, O; Vasilev, E

    2006-01-01

    A study on the effect of different rates of mineral fertilizer and manure on yield parameters of lucerne under optimal and water deficit conditions was carried out. Leached chernozem soil and lucerne cultivar Victoria were used. The soil was treated with ammonium nitrate and fully matured cattle manure. The plants were grown under optimum moisture content of 80% and 40% of field capacity. The water deficit stress decreased top and root biomass by 11-75% and 3-29% at mineral and organic fertilization, respectively. The applied mineral and organic N strongly depressed nodules development. Both mineral fertilizer and organic manure at dose of 210 mg N kg(-1) soil completely inhibited the appearance of nodules. Next to nitrogen, water deficit stress further inhibited the development of nodules. Nitrogen fertilization increased seed productivity in the two experimental moisture conditions. The water deficit stress decreased seed productivity by 18 to 33% as compared to optimum conditions. The plant treatments with manure were much more resistant to water deficit and recovering ability of plants was faster as compared to treatments with mineral fertilizer. The application of manure stimulates development of drought-stress tolerance in lucerne. However, the results obtained can be considered for the soil type and experimental conditions used.

    in shortening of the anogenital distance in adult offspring, suggesting that fetal hormone signaling had been disturbed. Female offspring of paracetamol-exposed mothers had ovaries with diminished follicle reserve and reduced fertility. Fetal gonads of exposed animals had also reduced gonocyte numbers......, suggesting that the reduced follicle count in adults could be due to early disruption of germ cell development. However, ex vivo cultures of ovaries from 12.5 days post coitum fetuses showed no decrease in proliferation or expression following exposure to paracetamol. This suggests that the effect...... of paracetamol occurs prior to this developmental stage. Accordingly, using embryonic stem cells as a proxy for primordial germ cells we show that paracetamol is an inhibitor of cellular proliferation, but without cytotoxic effects. Collectively, our data show that intrauterine exposure to paracetamol at levels...

    The authors analyze internal migration trends in Nigeria by examining individual household strategies and how they have adapted to structural changes brought about by colonial rule and capitalist development. The first section of this article describes the structural changes that started the process of labor migration. The second section deals with post-independence industrialization and the consequent rural-urban migration. The final section analyzes the consequences of these migration patterns for urban growth and rural productivity.

    Four kinds of organic-inorganic cementing and coating materials were prepared by a coating method using water as the solvent, and the corresponding cemented and coated fertilizers (B2, PS, F2, and F2F) were produced by disc pelletizer. The tests on the properties of these fertilizers showed that the granulation rate, compression strength, and film-forming rate were B2 > PS > F2 > F2F. Soil column leaching experiment showed that the curve of accumulated nitrogen-dissolving rate was the gentlest for B2. In 48 days, the accumulated nitrogen-dissolving rate was in the order of B2, 54.65% fertilizers had better effects on corn yield, among which, B2 was the best, with the corn yield and fertilizer use efficiency increased by 19.72% and 20.30%, respectively. The yield-increasing effect of other test fertilizers was in the order of PS > F2 > F2F.

    The US Department of Energy (DOE) and the Nuclear Energy Agency of the Organization for Economic Cooperation and Development/Nuclear Energy Agency (OECD/NEA) began to act on their recognition of the importance of education in nuclear literacy, specifically in radioactive waste management (RWM), several years ago. To address this Goal for nuclear literacy, the US DOE; through the Information and Education Division of the Office of Civilian Radioactive Waste Management (OCRWM) and in cooperation with the OECD/NEA, organized an ''International Workshop on Education in the Field of Radioactive Waste Management'' in Engelberg, Switzerland in June of 1991. To this end, a grant to support nuclear literacy and RWM was written and funded by the OCRWM and the education division of the DOE Yucca Mountain Office in 1990. The over-riding Goal of that workshop and the DOE grant was to find ways of raising the level of nuclear literacy in the general public through educational programs in radioactive waste management (RWM). The two Main Objectives of the workshop were: first, to contribute to an information base for education systems, on global aspects of radioactive waste management; and second, to achieve international consensus on the basic tools and methods required to develop the information base. These two objectives also became the principal objectives of the DOE International Workshops grant. In other words, the global and local (Nevada) objectives were one and the same. Workshop overviews and accomplishments are summarized in this report

  3. Development of a definitive internal dosimetry code

    International Nuclear Information System (INIS)

    Miller, G.; Inkret, W.C.; Schillaci, M.E.

    1996-01-01

    Internal dosimetry may be divided into tow main problems: (1) the forward (scientific) problem of determining biokinetics models that describe how radionuclides are taken into the body, distributed in body tissues, and excreted, and (2) the inverse (mathematical) problem: given the measured amounts in excreta and assuming a biokinetic model, to determine the times and amounts of intakes into the body. The inverse problem of internal dosimetry is, in fact, a generic problem studied in other fields (e.g., image reconstruction, spectral deconvulution, and model parameter fitting). We have developed a code for plutonium internal dosimetry using the maximum entropy method, a method for solving underdetermined inverse problems with a positivity constraint. Within the framework of Bayesian statistics, we believe the definitive approach is to examine the Bayesian posterior probability describing the probability of an intake scenario (X i ) read ( ... ) as open-quotes the set of,close quotes where X i denotes the intake amount that occurs on the with day. For plutonium, for a worker with a long employment history, this is a very high dimensional probability space, since there may be on the order of 10,000 days when intakes may have occurred. Within this high dimensional space, we calculate the mean intake scenario as i > where denotes the expectation value over the posterior probability distribution. Similarly, we calculate uncertainties and other relevant quantities, such as X 2 , as expectation values over the posterior distribution. Thanks to a recent breakthrough in describing the mathematical structure of the intake process (a Poisson sum representation of intakes), we have developed the initial version of a Bayesian expectation-value algorithm for internal dosimetry reconstructions

  4. Evaluation of internal alpha-particle radiation exposure and subsequent fertility among a cohort of women formerly employed in the radium dial industry

    Schieve, L.A.; Davis, F.; Freels, S.

    1997-01-01

    This study examined the effect of internal exposure to α-particle radiation on subsequent fertility among women employed in radium dial industry prior to 1930, when appreciable amounts of radium were often ingested through the practice of pointing the paint brush with the lips. The analysis was limited to women for whom a radium body burden measurement had been obtained and who were married prior to age 45 (n = 603). Internal radiation dose to the ovary was calculated based on initial intakes of radium-226 and radium-228, average ovarian mass, number and energy of α particles emitted, fraction of energy absorbed within the ovary, effective retention integrals and estimated photon irradiation. Time between marriage and pregnancy, number of pregnancies and number of live births served as surrogates for fertility. Radiation appeared to have no effect on fertility at estimated cumulative ovarian dose equivalents below 5 Sv; above this dose, however, statistically significant declines in both number of pregnancies and live births were observed. These trends persisted after multivariable adjustment for potential confounding variables and after exclusion of subjects contributing a potential classification or selection bias to the study. Additionally, the high-dose group experienced fewer live births than would have been expected based on population rates. There were no differences in time to first pregnancy between high- and low-dose groups. These results are consistent with earlier studies of γ-ray exposures and suggest that exposure to high doses of radiation from internally deposited radium reduces fertility rather than inducing sterility. 42 refs., 5 tabs

  5. Technical developments in international satellite business services

    Tan, P. P.

    At the conception of International Satellite Business Services (ISBS), it was a primary objective to provide flexibility for accommodating a variety of service requirements which might be established by mutual agreement between users. The design guidelines are to ensure that the space segment is efficiently utilized, while other satellite services are protected from interference. Other considerations are related to an acceptable earth segment cost, maximum connectivity in worldwide services, the capability of growth and a reasonably smooth transition into future systems, and the maintenance of high performance objectives. Attention is given to a system overview, the characteristics of satellites for ISBS, and technological developments with some application possibilities for ISBS.

    Molecular mechanisms underlying coral larval competence, the ability of larvae to respond to settlement cues, determine their dispersal potential and are potential targets of natural selection. Here, we profiled competence, fluorescence and genome-wide gene expression in embryos and larvae of the reef-building coral Acropora millepora daily throughout 12 days post-fertilization. Gene expression associated with competence was positively correlated with transcriptomic response to the natural settlement cue, confirming that mature coral larvae are "primed" for settlement. Rise of competence through development was accompanied by up-regulation of sensory and signal transduction genes such as ion channels, genes involved in neuropeptide signaling, and G-protein coupled receptor (GPCRs). A drug screen targeting components of GPCR signaling pathways confirmed a role in larval settlement behavior and metamorphosis. These results gives insight into the molecular complexity underlying these transitions and reveals receptors and pathways that, if altered by changing environments, could affect dispersal capabilities of reef-building corals. In addition, this dataset provides a toolkit for asking broad questions about sensory capacity in multicellular animals and the evolution of development.

  8. Development of space-fertilized eggs and formation of primordial germ cells in the embryos of medaka fish

    Science.gov (United States)

    Ijiri, K.

    In the second International Microgravity Laboratory (IML-2) mission in 1994, four small Japanese killifish (Medaka, Oryzias latipes) made a space travel of 15 days aboard a space shuttle. These four adult Medaka fish successfully mated in space for the first time among vertebrate animals. Moreover, the eggs they laid developed normally, at least in their external appearance, hatching as fry (baby fish) in space. Fish mated and laid eggs every day during the first week. Near the end of the mission most of the eggs had a well-developed body with two pigmented eyes. In total, 43 eggs were laid (detected), out of which 8 fry hatched in space, as truly `space-originated' babies. A further 30 fry hatched within 3 days after landing. This is the normal hatching rate, compared with the ground-based data. Among the 8 space-originated fry, four were killed for histological sections, and germ cells at the gonadal region were counted for each fry. Their numbers were in the range of the germ cells of the normal control fry (ground-kept samples). Thus, as embryos developed normally in their external appearance, inside the embryos the formation of primordial germ cells took place normally in space, and their migration to the genital ridges was not hindered by microgravity. The two of the remaining space-originated fry have grown up and been creating their offspring in the laboratory. This proved that the primordial germ cells formed in space were also normal from a functional point of view. The four space-travelled adult fish re-started mating and laying eggs on the 7th day after landing and continued to do so every day afterward. Fertilization rate and hatchability of these eggs were as high as the eggs laid by the laboratory-kept fish. This fact implies that in gametogenesis of adult fish, there are no specific stages of germ cells extremely susceptible to microgravity.

    Full Text Available Capitalism started as a consequence of the urban phenomena development, as well as of the commercial activities development. Thus, over this period of time, the attitude towards business also changed. This change was based also on certain economic reasons. The term „business” is defined in numerous dictionaries released until the present day in a restrictive and subjective manner, both from the perspective of the totalitarian communist ideology, which happened up to the year 1989, and also from the perspective of the different categories of meanings that were taken into consideration when compiling dictionaries in different international circulation languages. If an enterprise conducts business at an international level, then it will take into consideration the performance of different types of activities which differ greatly from the activities conducted at a national level. All these elements must be carefully studied by the company's management, in order to be able to act with high economic efficiency. It must be said that, in contemporary times, that „invisible hand of the market” from the past is none other than competition. As a consequence of the competitive phenomenon's manifestation, the prices are lower, the services are of a better quality and they are increasingly more diverse. Because of these positive arguments, Adam Smith was named „the father of economy”.

    The relationship between growth and fertilizer nitrogen recovery by perennial crops such as coffee is poorly understood and improved understanding of such relations is important for the establishment of rational crop management practices. In order to characterize the growth of a typical coffee crop in Brazil and quantify the recovery of 15 N labeled ammonium sulfate, and improve information for fertilizer management practices this study presents results for two consecutive cropping years, fertilized with 280 and 350 kg ha -1 of N, respectively, applied in four splittings, using five replicates. Shoot dry matter accumulation was evaluated every 60 days, separating plants into branches, leaves and fruits. Labeled sub-plots were used to evaluate N-total and 15 N abundance by mass spectrometry. During the first year the aerial part reached a recovery of 71% of the fertilizer N applied up to February, but this value was reduced to 34% at harvest and 19% at the beginning of the next flowering period due to leaf fall and fruit export. For the second year the aerial part absorbed 36% of the fertilizer N up to March, 47% up to harvest and 19% up to the beginning of the next flowering period. The splitting into four applications of the used fertilizer rates was adequate for the requirements of the crop at these growth stages of the coffee crop. (author)

  12. Pro-apoptotic Effect of Pifithrin-α on Preimplantation Porcine Fertilized Embryo Development

    2012-12-01

    Full Text Available The aim of this study was to investigate the impact of a reported p53 inhibitor, pifithrin-α (PFT-α, on preimplantation porcine in vitro fertilized (IVF embryo development in culture. Treatment of PFT-α was administered at both early (0 to 48 hpi, and later stages (48 to 168 hpi of preimplantation development, and its impact upon the expression of five genes related to apoptosis (p53, bak, bcl-xL, p66Shc and caspase3, was assessed in resulting d 7 blastocysts, using real-time quantitative PCR. Total cell numbers, along with the number of apoptotic nuclei, as detected by the in situ cell death detection assay, were also calculated on d 7 in treated and non-treated control embryos. The results indicate that PFT-α, when administered at both early and later stages of porcine IVF embryo development, increases the incidence of apoptosis in resulting blastocysts. When administered at early cleavage stages, PFT-α treatment was shown to reduce the developmental competence of porcine IVF embryos, as well as reducing the quality of resulting blastocysts in terms of overall cell numbers. In contrast, at later stages, PFT-α administration resulted in marginally increased blastocyst development rates amongst treated embryos, but did not affect cell numbers. However, PFT-α treatment induced apoptosis and apoptotic related gene expression, in all treated embryos, irrespective of the timing of treatment. Our results indicate that PFT-α may severely compromise the developmental potential of porcine IVF embryos, and is a potent apoptotic agent when placed into porcine embryo culture media. Thus, caution should be exercised when using PFT-α as a specific inhibitor of p53 mediated apoptosis, in the context of porcine IVF embryo culture systems.

  13. Gadd45g is essential for primary sex determination, male fertility and testis development.

    Directory of Open Access Journals (Sweden)

    Heiko Johnen

    Full Text Available In humans and most mammals, differentiation of the embryonic gonad into ovaries or testes is controlled by the Y-linked gene SRY. Here we show a role for the Gadd45g protein in this primary sex differentiation. We characterized mice deficient in Gadd45a, Gadd45b and Gadd45g, as well as double-knockout mice for Gadd45ab, Gadd45ag and Gadd45bg, and found a specific role for Gadd45g in male fertility and testis development. Gadd45g-deficient XY mice on a mixed 129/C57BL/6 background showed varying degrees of disorders of sexual development (DSD, ranging from male infertility to an intersex phenotype or complete gonadal dysgenesis (CGD. On a pure C57BL/6 (B6 background, all Gadd45g(-/- XY mice were born as completely sex-reversed XY-females, whereas lack of Gadd45a and/or Gadd45b did not affect primary sex determination or testis development. Gadd45g expression was similar in female and male embryonic gonads, and peaked around the time of sex differentiation at 11.5 days post-coitum (dpc. The molecular cause of the sex reversal was the failure of Gadd45g(-/- XY gonads to achieve the SRY expression threshold necessary for testes differentiation, resulting in ovary and Müllerian duct development. These results identify Gadd45g as a candidate gene for male infertility and 46,XY sex reversal in humans.

    The zona pellucida (ZP) is a unique extracellular coat surrounding the maturing oocyte, during ovulation, fertilization, and early embryo development. It is formed by three/four glycoproteins. Ultrastructural data obtained with transmission (TEM) and scanning electron microscopy (SEM) were compared with molecular data on the glycoproteins network from ovulation to blastocyst formation. Molecular models are quite different to the morphology obtained with TEM, which shows a microfibrillar architecture, or with SEM, which shows a spongy or smooth surface. The saponin-ruthenium red-osmium tetroxide-thiocarbohydrazide technique allows to show the ZP real microfilamentous structure and the related functional changes. These results support an ultrastructural supramolecular model, more similar and comparable to molecular models related with the glycoprotein network. A detailed mapping of single mammalian ZP proteins and their relationship within the supramolecular architecture of the zona matrix would clearly supply insights into the molecular basis of sperm-egg recognition. Differences in ZP glycoproteins among mammals do not affect structural morphology; further studies are needed to clarify the relationships between ultrastructural and molecular organizations.

    Full Text Available This study was designed to evaluate the efficacy of different somatic cell types and media in supporting in vitro maturation (IVM, in vitro fertilization (IVF and early embryonic development competence of buffalo follicular oocytes. Cumulus oocyte complexes were collected for maturation from follicles (>6mm of buffalo ovaries collected at the local abattoir. Oocytes were co-cultured in tissue culture medium (TCM-199 with either granulosa cells, cumulus cells, or buffalo oviductal epithelial cells (BOEC @ 3x106 cells/ml or in TCM-199 without helper cells (control at 39°C and 5%CO2 in humidified air. Fresh semen was prepared in modified Ca++ free Tyrode medium. Fertilization was carried out in four types of media: i Tyrode lactate albumin pyruvate (TALP, ii TALP+BOEC, iii modified Ca++ free Tyrode and iv modified Ca++ free Tyrode+BOEC. Fertilized oocytes were cultured for early embryonic development in TCM-199 with and without BOEC. Higher maturation rates were observed in the granulosa (84.24% and cumulus cells (83.44% than BOEC co culture system (73.37%. Highest fertilization rate was obtained in modified Ca++ free Tyrode with BOEC co culture (70.42%, followed by modified Ca++ free Tyrode alone (63.77%, TALP with BOEC (36.92% and TALP alone (10.94%. Development of early embryos (8-cell stage improved in TCM-199 with BOEC co culture than TCM-199 alone. From the results of this study, it can be concluded that addition of somatic cells (granulosa cells, cumulus cells results in higher maturation rates of buffalo follicular oocytes than BOEC co culture system, while fertilization rate improved in modified Ca++ free Tyrode with and without BOEC. Addition of BOEC to TCM-199 improved the developmental capacity of early embryo.

  18. A review of international underground laboratory developments

    2011-01-01

    Underground laboratories are essential for various important physics areas such as the search for dark matter, double beta decay, neutrino oscillation, and proton decay. At the same time, they are also a very important location for studying rock mechanics, earth structure evolution,and ecology. It is essential for a nation's basic research capability to construct and develop underground laboratories. In the past, China had no high-quality underground laboratory,in particular no deep underground laboratory,so her scientists could not work independently in major fields such as the search for dark matter,but had to collaborate with foreign scientists and share the space of foreign underground laboratories. In 2009, Tsinghua university collaborated with the Ertan Hydropower Development Company to construct an extremely deep underground laboratory, the first in China and currently the deepest in the world, in the Jinping traffic tunnel which was built to develop hydropower from the Yalong River in Sichuan province. This laboratory is named the China Jinping Underground Laboratory (CJPL) and formally opened on December 12, 2010. It is now a major independent platform in China and can host various leading basic research projects. We present a brief review of the development of various international underground laboratories,and especially describe CJPL in detail. (authors)

    Full Text Available Education has been a priority sector when considering foreign aid allocationsince the 1970s. The stated objective has been to ensure universal access to basic education, with a more recent emphasis on quality and outcomes. Aware that these goals will not be met universally, the major actors involved in the post-2015 debate are turning back to the concept of learning. In this chapter, we briefly review major scholarly work and strategic papers that have shaped the discourse and policies of international development organisations and national actors over the past four decades. We discuss how the central notions of skills, learning, and both formal and non-formal education have evolved in conjunction with ideological shifts. We examine the tensions between public and private education as well as between individualised and standardised delivery modes. We further look at (big data and online education promises. To conclude, we question the current focus of major stakeholders on post-2015, post-EFA agendas. As several articles in this special issue underscore, national policies and local practices are largely driven by persistent political economy dynamics while the influence of ‘the global agenda’ tends to remain confined to the international cooperation community itself.

  1. Below Replacement-Level Fertility in Conditions of slow Social and Economic Development: A Review of the Evidence from South-India

    Directory of Open Access Journals (Sweden)

    Minna Säävälä

    2010-01-01

    Full Text Available Demographic interest in the explanations of the first fertility transition has receded considerably during the last decade. Despite the empirical evidence of global convergence in fertility, there is still no consensus on the factors which explain the swiftness of the change in some contexts and its deceleration in some others. From the policy perspective, it remains pivotal to locate the factors that affect the momentum of fertility transition. In this essay the fast decline to below replacement-level period Total Fertility Rate in South India will be examined as an example of fertility transition despite slow social and/or economic development. The analysis is based on a literature review of empirical studies on the determinants of regional fertility differentials in India. Some southern states, most particularly Andhra Pradesh, manifest below replacement-level fertility (TFR 1.79 despite low average age at marriage even in Indian terms, the resilience of womens universal marriage, and heavy reliance on a terminal family planning method, female sterilization. The case of Andhra Pradesh shows that below-replacement level fertility can occur despite slow social development, widespread poverty and gender asymmetries. Geographical and social diffusion effects are partly responsible of the speed of the decline, although they are difficult to measure or test in the level of fertility decision-making.

  12. From Fertilization to Birth: Representing Development in High School Biology Textbooks

    Science.gov (United States)

    Wellner, Karen L.

    Biology textbooks are everybody's business. In accepting the view that texts are created with specific social goals in mind, I examined 127 twentieth-century high school biology textbooks for representations of animal development. Paragraphs and visual representations were coded and placed in one of four scientific literacy categories: descriptive, investigative, nature of science, and human embryos, technology, and society (HETS). I then interpreted how embryos and fetuses have been socially constructed for students. I also examined the use of Haeckel's embryo drawings to support recapitulation and evolutionary theory. Textbooks revealed that publication of Haeckel's drawings was influenced by evolutionists and anti-evolutionists in the 1930s, 1960s, and the 1990s. Haeckel's embryos continue to persist in textbooks because they "safely" illustrate similarities between embryos and are rarely discussed in enough detail to understand comparative embryology's role in the support of evolution. Certain events coincided with changes in how embryos were presented: (a) the growth of the American Medical Association (AMA) and an increase in birth rates (1950s); (b) the Biological Sciences Curriculum Study (BSCS) and public acceptance of birth control methods (1960s); (c) Roe vs. Wade (1973); (d) in vitro fertilization and Lennart Nilsson's photographs (1970s); (e) prenatal technology and fetocentrism (1980s); and (f) genetic engineering and Science-Technology-Society (STS) curriculum (1980s and 1990s). By the end of the twentieth century, changing conceptions, research practices, and technologies all combined to transform the nature of biological development. Human embryos went from a highly descriptive, static, and private object to that of sometimes contentious public figure. I contend that an ignored source for helping move embryos into the public realm is schoolbooks. Throughout the 1900s, authors and publishers accomplished this by placing biology textbook embryos and

  14. Mortality-fertility synergies during the demographic transition in the developed world.

    Science.gov (United States)

    Sánchez-Barricarte, Jesús J

    2017-07-01

    The classic theory used to explain the demographic transition assumes that mortality is the key explanatory variable influencing the decline in fertility. However, the empirical results obtained in what is known as the Princeton European Fertility Project have led many specialists to question this assumption. Using both national and provincial aggregated data for 25 countries over a long time span, the analysis reported in this paper found that mortality does indeed play a fundamental role in accounting for the main demographic changes that occurred both before and during the transitional period. Others' research based on individual data has shown clearly that the number of surviving children was indeed an important factor for reproductive decisions. My analysis, using aggregated data, reached largely similar conclusions regarding the role of mortality in changing reproductive trends, via its impact on nuptiality and marital fertility at different stages of the demographic transition.

    Sources of mineral phosphorus (P) fertilizers are non-renewable. Although the longevity of P mines and the risk of future P depletion are highly debated P scarcity may be detrimental to agriculture in various ways. Some of these impacts include increasing food insecurity and nitrogen (N) and P imbalances, serious fluctuations in the global fertilizer and crop market prices, and contribution in geopolitical conflicts. P-rich waste produced from livestock production activities (i.e. manure) are an alternative to mineral P fertilizer. The substitution of mineral fertilizer with manure (1) delays the depletion of phosphate rock stocks, (2) reduces the vulnerability of P fertilizer importing countries to sudden changes in the fertilizer market, (3) reduces the chances of geopolitical conflicts arising from P exploitation pressures, (4) avoids the need for environmental protection policies in livestock systems, (5) is an opportunity for the boosting of crop yields in low nutrient input agricultural systems, and (6) contributes to the inflow of not only P but also other essential nutrients to agricultural soils. The Environmental Policy Integrated Climate model (EPIC) is a widely used process-based, crop model integrating various environmental flows relevant to crop production as well as environmental quality assessments. We simulate crop yields using a powerful computer cluster infra-structure (known as EPIC-IIASA) in combination with spatially-explicit EPIC input data on climate, management, soils, and landscape. EPIC-IIASA contains over 131,000 simulation units and it has 5 arc-min resolution. In this work, we implement two process-based models of manure biogeochemistry into EPIC-IIASA, i.e. SurPhos (for P) and Manure DNDC (for N and carbon) and a fate model model describing nutrient outflows from fertilizer via runoff. For EGU, we will use EPIC-IIASA to quantify the potential of mineral P fertilizer substitution with manure. Specifically, we will estimate the relative

    Improving in vitro maturation could increase the rate of pregnancy from oocytes matured in vitro. Consequently, patients will be prevented from using gonadotropin with its related side effects. In this study, the maturation medium was enriched by platelet lysate (PL), then maturation and subsequent developments were monitored. Oocytes at germinal vesicle stage with cumulus cells (cumulus-oocyte complex) and without cumulus cells (denuded oocytes) were obtained from mature female mice. The maturation medium was enriched by 5 and 10 % PL and 5 % PL + 5 % fetal bovine serum (FBS) as experimental groups; the control groups' media consisted of 5 and 10 % FBS. After 18 h, the matured oocytes were collected and, after fertilization, subsequent development was monitored. The rates of maturation, fertilization and 2-cell embryo development for the denuded oocyte groups in experimental media 5 % PL and 5 % PL + 5 % FBS were significantly higher than those of the control groups ( P platelet lysate could improve the maturation rate in the absence of granulosa cells compared to media with FBS. This extract also had positive effects on fertilization and embryo development.

  19. Toward developing recombinant gonadotropin-based hormone therapies for increasing fertility in the flatfish Senegalese sole.

    Directory of Open Access Journals (Sweden)

    François Chauvigné

    Full Text Available Captive flatfishes, such as the Senegalese sole, typically produce very low volumes of sperm. This situation is particularly prevalent in the first generation (F1 of reared sole males, which limits the development of artificial fertilization methods and the implementation of selective breeding programs. In this study, we investigated whether combined treatments with homologous recombinant follicle-stimulating (rFsh and luteinizing (rLh hormones, produced in a mammalian host system, could stimulate spermatogenesis and enhance sperm production in Senegalese sole F1 males. In an initial autumn/winter experiment, weekly intramuscular injections with increasing doses of rFsh over 9 weeks resulted in the stimulation of gonad weight, androgen release, germ cell proliferation and entry into meiosis, and the expression of different spermatogenesis-related genes, whereas a subsequent single rLh injection potentiated spermatozoa differentiation. In a second late winter/spring trial corresponding to the sole's natural prespawning and spawning periods, we tested the effect of repeated rLh injections on the amount and quality of sperm produced by males previously treated with rFsh for 4, 6, 8 or 10 weeks. These latter results showed that the combination of rFsh and rLh treatments could increase sperm production up to 7 times, and slightly improve the motility of the spermatozoa, although a high variability in the response was found. However, sustained administration of rFsh during spawning markedly diminished Leydig cell survival and the steroidogenic potential of the testis. These data suggest that in vivo application of rFsh and rLh is effective at stimulating spermatogenesis and sperm production in Senegalese sole F1 males, setting the basis for the future establishment of recombinant gonadotropin-based hormone therapies to ameliorate reproductive dysfunctions of this species.

    Full Text Available Business Logistics and Supply Chain Management (SCM are relatively new terms that emerged in recent years concerning to be modern terms compared to the more traditional fields of production, marketing or finance. By opening new stores globally, from which to source products, by increasing the number of retailers, wholesalers, agents and distributers in the global supply chain, as well as easing global transport, these events dramatically changed the way business looked at managing its physical operations. Therefore, this paper offers deep understanding of the main characteristics, new trends and evaluation of global logistics which referred to as global supply chain management. Global logistics plays critical role in the growth and development of world trade, and in the integration of business operations on a worldwide scale. This paper also emphasizes the differences between traditional and global supply chains, by explaining several alternative types of distribution channels that are part of the international distribution channels. Also, real world examples of global organizations and their global supply chain management processes are accurately described in the end of this paper.

  5. Development of new historical global Nitrogen fertilizer map and the evaluation of their impacts on terrestrial N cycling and the evaluation of their impacts on terrestrial N cycling

    2015-12-01

    The use of synthetic nitrogen fertilizer was rapidly growing up after the birth of Haber-Bosch process in the early 20th century. The recent N loading derived from these sources on terrestrial ecosystems was estimated 2 times higher than biogenic N fixation in terrestrial ecosystems (Gruber et al., 2009). However, there are still large uncertainties in cumulative N impacts on terrestrial impact at global scale. In this study, to assess historical N impacts at global scale, we made a new global N fertilizer input map, which was a spatial-temporal explicit map (during 1960-2010) and considered the fraction of NH4+ and NO3- in the N fertilizer inputs. With the developed N fertilizer map, we evaluated historical N20 cycling changes by land-use changes and N depositions in N cycling using ecosystem model 'VISIT'. Prior to the downscaling processes for global N fertilizer map, we applied the statistical data imputation to FAOSTAT data due to there existing many missing data especially in developing countries. For the data imputation, we used multiple data imputation method proposed by Honaker & King (2010). The statistics of various types of synthetic fertilizer consumption are available in FAOSTAT, which can be sorted by the content of NH4+ and NO3-, respectively. To downscaling the country by country N fertilizer consumptions data to the 0.5˚x 0.5˚ grid-based map, we used historical land-use map in Earthstat (Rumankutty et al., 1999). Before the assignment of N fertilizer in each grid, we weighted the double cropping regions to be more N fertilizer input on to these regions. Using M3-Crops Data (Monfreda et al., 2008), we picked up the dominant cropping species in each grid cell. After that, we used Crop Calendar in SAGE dataset (Sacks et al., 2010) and determined schedule of N fertilizer input in each grid cell using dominant crop calendar. Base fertilizer was set to be 7 days before transplanting and second fertilizer to be 30 days after base fertilizer application

    1992-01-01

    Egg rotation and centrifugation experiments strongly suggest a role for gravity in the determination of the spatial structure of amphibian embryos. Decisive experiments can only be made in Space. Eggs of Xenopus laevis, the South African clawed toad, were the first vertebrate eggs which were successfully fertilized on Sounding Rockets in Space. Unfixed, newly fertilized eggs survived reentry, and a reasonable number showed a seemingly normal gastrulation but died between gastrulation and neurulation. Only a few reached the larval stage, but these developed abnormally. In the future, we intend to test whether this abnormal morphogenesis is due to reentry perturbations, or due to a real microgravity effect, through perturbation of the reinitiation of meiosis and other processes, or started by later sperm penetration.

    2016-01-01

    Full Text Available Purpose. This study was aimed to investigate the reproductive toxicity of Zishen Yutai Pill (ZYP on fertility and early embryonic development in rats. Methods. SD rats were randomly divided into 5 groups: vehicle control group (distilled water, i.g., positive control group (80 mg/kg of cyclophosphamide, i.p., and three ZYP-treated groups (3, 6, and 12 g/kg/d, i.e., 12x, 24x, and 48x clinical doses, i.g.. The high dose was set as the maximum gavage dosage. Results. Cyclophosphamide showed diverse hazards, such as decreased weight of male reproductive organs and sperm density (P<0.05. However, there were no obvious effects of ZYP on physical signs, animal behavior, and survival rate, as well as on weight and food intake during the premating and gestation periods. Importantly, there were no significant adverse effects of ZYP on indexes of copulation, fecundity and fertility indexes, weights and coefficients of male reproductive organs, epididymal sperm number and motility, estrous cycle, preimplantation loss rate, and implantation rate. Besides, the numbers of live and resorbed fetuses per litter were not significantly altered. Conclusions. ZYP had no reproductive toxicities on fertility and early embryonic development in rats at 48x equivalent clinical doses.

  18. The functional role of insulin in fertility and embryonic development-What can we learn from the bovine model?

    Insulin is a key metabolic hormone that plays a crucial role in regulating energy homeostasis in the body. In addition, insulin-dependent signaling has important functions in reproduction and early embryo development. As metabolism and reproduction are closely linked, metabolic challenges may be the source of reproductive disorders and decreased fertility. This is known for the dairy cow and for other species including the human. Although metabolic disorders in the dairy cow often derive from a failure to adapt to a high milk production, the situation in the human is often linked to emerging conditions and associated diseases in our modern society such as obesity and diabetes, where an excess energy intake causes decreased fertility in women. Both energy excess and energy deficit are associated with a deviation of insulin concentrations in serum and follicular fluid from normal levels. Although many studies have shown that extreme variation in energy supply can negatively influence early embryo development by inducing changes in circulating concentrations of several metabolites or hormones like insulin, several in vitro culture media are still supplemented with insulin in high concentrations. In this review, direct and indirect effects of insulin on fertility will be described. Differences between the in vivo and in vitro situations will also be discussed. Copyright © 2016 Elsevier Inc.

  19. Development of a High Irradiance LED Configuration for Small Field of View Motion Estimation of Fertilizer Particles

    Directory of Open Access Journals (Sweden)

    Simon Cool

    2015-11-01

    Full Text Available Better characterization of the fertilizer spreading process, especially the fertilizer pattern distribution on the ground, requires an accurate measurement of individual particle properties and dynamics. Both 2D and 3D high speed imaging techniques have been developed for this purpose. To maximize the accuracy of the predictions, a specific illumination level is required. This paper describes the development of a high irradiance LED system for high speed motion estimation of fertilizer particles. A spectral sensitivity factor was used to select the optimal LED in relation to the used camera from a range of commercially available high power LEDs. A multiple objective genetic algorithm was used to find the optimal configuration of LEDs resulting in the most homogeneous irradiance in the target area. Simulations were carried out for different lenses and number of LEDs. The chosen configuration resulted in an average irradiance level of 452 W/m2 with coefficient of variation less than 2%. The algorithm proved superior and more flexible to other approaches reported in the literature and can be used for various other applications.

So today one can easily familiarize with foreign laws on intellectual property, due to their increasing uniformity and homogeneity. This is the result of numerous international treaties and two international organizations. At the multilateral level, the World Intellectual Property Organization (WIPO) administers 24 treaties on intellectual property, and for its part, the World Trade Organization (WTO) is i...

    A short overview is given of the most important international conventions relating to civil liability for damage to, or loss of, life of persons or property, caused by nuclear incidents during the operation of stationary and non-stationary nuclear installations or transport of nuclear material. In accord with the international provisions, in the German Democratic Republic too, nuclear operators are exclusively liable for such damage unless it has been caused intentionally by the injury party.

  20. Effects of the toxic benthic dinoflagellate Ostreopsis cf. ovata on fertilization and early development of the sea urchin Lytechinus variegatus.

    Science.gov (United States)

    Neves, Raquel A F; Contins, Mariana; Nascimento, Silvia M

    2018-04-01

    Blooms of the benthic dinoflagellate Ostreopsis cf. ovata have been recorded with increasing frequency, intensity and geographic distribution. This dinoflagellate produces potent toxins that may cause mortality of marine invertebrates. Adults of sea urchins are commonly affected by O. cf. ovata exposure with evidence of spines loss and high mortality during periods of high dinoflagellate abundances. Here, we report on the effects of the toxic dinoflagellate O. cf. ovata on fertilization and early development of the sea urchin Lytechinus variegatus, a key ecological herbivore. Lytechinus variegatus eggs and sperm were experimentally exposed to different concentrations of Ostreopsis cf. ovata (4, 40, 400, and 4000 cells ml -1 ) to test the hypothesis that fertilization success, embryonic and larval development of the sea urchin are negatively affected by the toxic dinoflagellate even at low abundances. Reduced fertilization, developmental failures, embryo and larval mortality, and occurrence of abnormal offspring were evident after exposure to O. cf. ovata. Fertilization decreased when gametes were exposed to high O. cf. ovata abundances (400 and 4000 cells ml -1 ), but just the exposure to the highest abundance significantly reduced fertilization success. Sea urchin early development was affected by O. cf. ovata in a dose-dependent way, high dinoflagellate abundances fully inhibited the early development of L. variegatus. Ostreopsis cf. ovata significantly increased the mortality of sea urchin eggs and embryos in the first hours of exposure (∼1-3 h), regardless of dinoflagellate abundance. Abundances of 400 and 4000 O. cf. ovata cells ml -1 induced significantly higher mortality on sea urchin initial stages in the first hours, and no egg or embryo was found in these treatments after 18 h of incubation. The early echinopluteus larva was only reached in the control and in treatments with low Ostreopsis cf. ovata abundances (4 and 40 cells ml -1 ). The

    Full Text Available Abstract Although much is known about the reproductive biology of pond-breeding frogs, there is comparatively little information about terrestrial-breeding anurans, a highly successful and diverse group. This study investigates the activation and in vitro fertilization of eggs of the Puerto Rican coqui frog obtained by hormonally induced ovulation. We report that spontaneous activation occurs in 34% of eggs, probably in response to mechanical stress during oviposition. Artificial activation, as evidenced by the slow block to polyspermy and the onset of zygote division, was elicited both by mechanical stimulation and calcium ionophore exposure in 64% and 83% of the cases, respectively. Finally, one in vitro fertilization protocol showed a 27% success rate, despite the fact that about one third of all unfertilized eggs obtained by hormone injection auto-activate. We expect these findings to aid in the conservation effort of Eleutherodactylus frogs, the largest vertebrate genus.

  4. Use of Bio-Organic Fertilizers to Develop N Uptake Using 15N Technique

    International Nuclear Information System (INIS)

    Galal, Y.G.M.

    2008-01-01

    Experimental work either in field scale or in green house conditions were conducted using 15 N technique to evaluate the role of different bio fertilizers and different plant residues as organic amendments on enhancement of plant N nutrition. Nitrogen fixation by a symbiotic bacteria has been observed in greenhouse and field experiments under dry land cropping systems. Biological N 2 fixation associated with crop residues (legumes or cereals) was investigated in pot experiments with wheat and chickpea cultivars. In these experiments, labelled wheat and rice straw were used as organic N sources in comparison with either 15 N-labelled ammonium sulfate or ammonium nitrate as chemical nitrogen fertilizers. Rhizobium inoculation extended to be used with wheat gave the best results of N uptake and N 2 fixation when combined with Azospirillum brasilense as heterotrophic diazotrophs. The nitrogen uptake by wheat plants was significantly increased by application of soybean residues and inoculation with Azospirillum brasilense. From the field trial we can conclude that soybean residue as enriched N material, and Azospirillum brasilense inoculation enhanced N yields of wheat cultivars grown in poor fertile sandy soil

  5. Ultrastructural dynamics of human reproduction, from ovulation to fertilization and early embryo development.

    This study describes the updated, fine structure of human gametes, the human fertilization process, and human embryos, mainly derived from assisted reproductive technology (ART). As clearly shown, the ultrastructure of human reproduction is a peculiar multistep process, which differs in part from that of other mammalian models, having some unique features. Particular attention has been devoted to the (1) sperm ultrastructure, likely "Tygerberg (Kruger) strict morphology criteria"; (2) mature oocyte, in which the MII spindle is barrel shaped, anastral, and lacking centrioles; (3) three-dimensional microarchitecture of the zona pellucida with its unique supramolecular filamentous organization; (4) sperm-egg interactions with the peculiarity of the sperm centrosome that activates the egg and organizes the sperm aster and mitotic spindles of the embryo; and (5) presence of viable cumulus cells whose metabolic activity is closely related to egg and embryo behavior in in vitro as well as in vivo conditions, in a sort of extraovarian "microfollicular unit." Even if the ultrastructural morphodynamic features of human fertilization are well understood, our knowledge about in vivo fertilization is still very limited and the complex sequence of in vivo biological steps involved in human reproduction is only partially reproduced in current ART procedures.

  6. Development of a rapid and efficient microinjection technique for gene insertion into fertilized salmonid eggs

    Energy Technology Data Exchange (ETDEWEB)

    Chandler, D.P.; Welt, M.; Leung, F.C.

    1990-10-01

    An efficient one-step injection technique for gene insertion into fertilized rainbow trout (Oncorhynchus mykiss) eggs is described, and basic parameters affecting egg survival are reported. Freshly fertilized rainbow trout eggs were injected in the perivitelline space with a recombinant mouse metallothionein-genomic bovine growth hormone (bGH) DNA construct using a 30-gauge hypodermic needle and a standard microinjection system. Relative to control, site of injection and DNA concentration did not affect the egg survival, but injections later than 3--4 hours post fertilization were detrimental. The injection technique permitted treatment of 100 eggs/hr with survivals up to 100%, resulting in a 4% DNA uptake rate as indicated by DNA dot blot analysis. Positive dot blot results also indicated that the injected DNA is able to cross the vitelline membrane and persist for 50--60 days post hatching, obviating the need for direct injection into the germinal disk. Results are consistent with previous transgenic fish work, underscoring the usefulness of the technique for generating transgenic trout and salmonids. 24 refs., 6 figs., 3 tabs.

    Full Text Available Aim: The effects of N-P-K fertilizers in the form of urea, single super phosphate and muriate of potash on development of free-living stages of Haemonchus contortus were studied. Materials and Methods: Five parasite free experimental plots of 1 mx1 m area, each of paddy leaves (15-day-old and an equal number of Cynodon dactylon grass were infested with about 10x104 eggs/ml phosphate buffer saline along with the application of the calculated amount of fertilizers solution. On the 10th day of posttreatment, the pasture was cut, processed, larvae recovered by Baermann method and counted, which was expressed as number of L3 per kg dry matter (DM of pasture. Results: The average recovered population of L3 of H. contortus per kg DM varied significantly (p0.05. Conclusion: This study shown that when N-P-K fertilizers administered at recommended level, significantly reduced larval translation of H. contortus minimizing pasture infectivity for the free range grazing animals.

  9. International Convention on the Rights of Persons with Disability: Disability Inclusive Development and International Development Cooperation

    Directory of Open Access Journals (Sweden)

    Full Text Available The adoption of the International Convention on the Rights of Persons with Disabilities is a historical momentum for disabled persons and their associates, as well as ODA workers in the development cooperation field all over the world. For the last two decades, persons with disabilities, their associates and professionals working in this field have promoted their human rights, equality, nondiscrimination and full participation. This Convention is beyond the concept of non-discrimination, and it is very comprehensive in its structure, scope and coverage, promoting developmental activities too in order to realize disabled people’s socio-economic rights. Furthermore it calls for international and regional development cooperation. Prior to its adoption, in September 2000 at the Millennium Summit the Member States of the Untied Nations issued the Millennium Declaration, committing themselves to a series of development targets, most of which are to be achieved by 2015. Known as the Millennium Development Goals (MDGs, they represent a framework for achieving sustainable and "just" human development through broadening the benefits of development for all categories individuals, women and men, the poor and the rich, the disabled and the non-disabled. The very first goal of the MDG is the eradication of extreme poverty and hunger. Poverty is both a cause and consequence of disability. Poverty and disability reinforce one another. Thus, it is necessary to ensure that persons with disabilities be an integral part of efforts to achieve MDGs, particularly in the areas of poverty alleviation, primary education, gender, employment and international development cooperation. In the Asian and Pacific region, the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP has proclaimed two decades of disabled persons 1993-2002, and 2003-2013 (to which Iran became a signatory in 1994, and promoted the inclusive, barrier-free and rights
