    BACKGROUND: Spontaneous abortion is the most commonly observed adverse pregnancy outcome. The angiogenic factors soluble Fms-like kinase 1 and placental growth factor are critical for normal pregnancy and may be associated to spontaneous abortion. OBJECTIVE: We investigated the association between...... maternal serum concentrations of soluble Fms-like kinase 1 and placental growth factor, and subsequent spontaneous abortion. STUDY DESIGN: In the prospective observational Odense Child Cohort, 1676 pregnant women donated serum in early pregnancy, gestational week ..., interquartile range 71-103). Concentrations of soluble Fms-like kinase 1 and placental growth factor were determined with novel automated assays. Spontaneous abortion was defined as complete or incomplete spontaneous abortion, missed abortion, or blighted ovum

    The spontaneous abortion is a common type of pregnant outcomes. The spontaneous abortion rate can be used to indicate the women's fecundity and the level of the reproductive health. It is also a sensitive indicator for determing the social, economic, and health status and prenatal care. To explore the preventive method for spontaneous abortion and improve women's health level, it is important to evaluate the status of spontaneous abortion and to determine the factors affecting

    Full Text Available Background: Spontaneous abortion is the most common adverse pregnancy outcome. We aimed to investigate a possible link between nutrient deficiencies and the risk of spontaneous abortion. Materials and Methods: This case-control study included the case group (n=331 experiencing a spontaneous abortion before 14 weeks of pregnancy and the control group (n=331 who were healthy pregnant women over 14 weeks of pregnancy. The participants filled out Food Frequency Questionnaire (FFQ, in which they reported their frequency of consumption for a given serving of each food item during the past three months, on a daily, weekly or monthly basis. The reported frequency for each food item was converted to a daily intake. Then, consumption of nutrients was compared between the two groups. Results: There are significant differences between the two groups regarding consumed servings/day of vegetables, bread and cereal, meat, poultry, fish, eggs, beans, fats, oils and dairy products (P=0.012, P<0.001, P=0.004, P<0.001, P=0.019, respectively. There are significant differences between the two groups in all micronutrient including folic acid, iron, vitamin C, vitamin B6, vitamin B12 and zinc (P<0.001. Conclusion: Poor nutrientions may be correlated with increased risk of spontaneous abortion

    Does the incidence of spontaneous abortion correlate positively over conception cohorts with the incidence of non-clinically indicated induced abortion as predicted by shared risk aversion? We find that the number of spontaneous and non-clinically indicated induced abortions correlates in conception cohorts, suggesting that risk aversion affects both the conscious and non-conscious mechanisms that control parturition. Much literature speculates that natural selection conserved risk aversion because the trait enhanced Darwinian fitness. Risk aversion, moreover, supposedly influences all decisions including those that individuals can and cannot report making. We argue that these circumstances, if real, would manifest in conscious and non-conscious decisions to invest in prospective offspring, and therefore affect incidence of induced and spontaneous abortion over time. Using data from Denmark, we test the hypothesis that monthly conception cohorts yielding unexpectedly many non-clinically indicated induced abortions also yield unexpectedly many spontaneous abortions. The 180 month test period (January 1995 through December 2009), yielded 1 351 800 gestations including 156 780 spontaneous as well as 233 280 induced abortions 9100 of which were clinically indicated. We use Box-Jenkins transfer functions to adjust the incidence of spontaneous and non-clinically indicated induced abortions for autocorrelation (including seasonality), cohort size, and fetal as well as gestational anomalies over the 180-month test period. We use cross-correlation to test our hypothesized association. We find a positive association between spontaneous and non-clinically indicated induced abortions. This suggests, consistent with our theory, that mothers of conception cohorts that yielded more spontaneous abortions than expected opted more frequently than expected for non-clinically indicated induced abortion. Limitations of our work include that even the world's best registration system

    Objective To investigate the effects of allograft inflammatory factor-1(AIF-1)and (RANTES) in sera and deciduas on unexplained early spontaneous abortion.Methods AIF-1 and RANTES were examined in sera and deciduas/endometria of 43 unexplained early spontaneous abortion women (group A),40 healthy women with early pregnancy(group B)and 20 healthy women with no pregnancy (group C). Immunohistochemistry and enzyme linked immunosorbent assay (ELISA) were used in this study. Results AIF-1 protein was expressed both in deciduas of group A and in endometria of group C.In group A, H scores in the recurrent abortion deciduas specimens were significantly greater than those in the first abortion;in endometrium,expression of AIF-1 was greater in the secretory than in proliferative phase of group C.In group B,concentrations of RANTES in sera were higher in 7th-8th week of pregnancy than in 6th-7th and >8th week of pregnancy;expression of AIF-1 protein showed a negative correlation with RASNTES concentration;a significant increase of the RANTES levels in sera and tissue was observed in group B. Conclusion These results demonstrate, for the first time,that AIF-1 are expressed in deciduas of unexplained spontaneous abortion suggesting that AIF-1 involve in alloimmune abortion; RANTES might act as a novel blocking antibody;AIF-1 and RANTES might act as reliable markers for diagnosis of early alloimmune abortion.

    Full Text Available This paper analyzes the attitudes of low-income women towards abortion and contraception. A survey was conducted in 1992 with a total of 3,149 childbearing-age women living on the outskirts of the Greater Metropolitan São Paulo Area. The study focuses on a sub-sample of 583 women. Attitudes of sterilized and non-sterilized women are compared. Women, especially those sterilized, found the most important attribute of a contraceptive method to be its effectiveness. Women currently taking the pill were less likely than those sterilized to agree that sterilization was the best method because of its effectiveness. Sterilized women were less likely than non-sterilized women to trust the pill. Sterilized women were more likely than non-sterilized to have reported adverse effects from the pill. Most women found abortion unacceptable except in the case of risk to the woman's life. Women using more effective methods showed stronger negative attitudes towards abortion. The tendency to be sterilized while still young was associated with more negative attitudes towards abortion. Family planning activities in basic health care services should include individual counseling for contraceptive use.

    Recurrent spontaneous abortion (RSA) is defined as three or more sequential abortions before the twentieth week of gestation. There are evidences to support an allo-immunologic mechanism for RSA. One of the methods for treatment of RSA is leukocyte therapy; however there is still controversy about effectiveness of this method. To evaluate the effectiveness of leukocyte therapy for treatment of RSA. Ninety two non-pregnant women with at least three sequential abortions (60 primary & 32 secondary aborters) recognized as RSA were referred to our Laboratory for immunotherapy. All the cases were immunized by isolated lymphocytes from their husbands. Fifty to 100 million washed and resuspended mononuclear cells were injected by I.V., S.C., and I.D. route. The result of each injection was checked by WBC cross matching between couples after four weeks of injections. Immunization was repeated in fifth week to a maximum of 3 times if needed. Eighty one age-matched non-pregnant RSA women (52 primary and 29 secondary aborters) with at least three sequential abortions were also included in this study as controls. The control group was not immunized. 67 out of 92 (72.8%) immunized cases and 44 out of 81 controls (54.3%) showed a successful outcome of pregnancy (pRSA patients. Despite the current controversy and limitation of leukocyte therapy in RSA, the results of our investigation provide evidence supporting the use of allo-immunization in improving the outcome of pregnancy in primary RSA patients.

  1. Spontaneous abortion and unexpected death: a critical discussion of Marquis on abortion.

    Science.gov (United States)

    Coleman, Mary Clayton

    2013-02-01

    In his classic paper, 'Why abortion is immoral', Don Marquis argues that what makes killing an adult seriously immoral is that it deprives the victim of the valuable future he/she would have otherwise had. Moreover, Marquis contends, because abortion deprives a fetus of the very same thing, aborting a fetus is just as seriously wrong as killing an adult. Marquis' argument has received a great deal of critical attention in the two decades since its publication. Nonetheless, there is a potential challenge to it that seems to have gone unnoticed. A significant percentage of fetuses are lost to spontaneous abortion. Once we bring this fact to our attention, it becomes less clear whether Marquis can use his account of the wrongness of killing to show that abortion is the moral equivalent of murder. In this paper, I explore the relevance of the rate of spontaneous abortion to Marquis' classic anti-abortion argument. I introduce a case I call Unexpected Death in which someone is about to commit murder, but, just as the would-be murderer is about to strike, his would-be victim dies unexpectedly. I then ask: what does Marquis' account of killing imply about the moral status of what the would-be murderer was about to do? I consider four responses Marquis could give to this question, and I examine what implications these responses have for Marquis' strategy of using his account of the wrongness of killing an adult to show that abortion is in the same moral category.

    Objective To investigate the factors resulting in spontaneous abortion after transferring frozen-thawing blastocysts. Methods A total of 108 cases transferring vitrified blastocysts were divided into two groups: abortion group (n =20) and ongoing group (n=88). Cytogenetic analysis of apoblemas was performed in 12 cases of the abortion.Results The overall spontaneous abortion rate was 18.50%(20/108) and the early spontaneous rate was 16.67%(18/108). ,4 significant difference in maternal age was observed (abortion group: 33.3±4.0 years, ongoing group: 31.0±3.6 years, P=0.02). No difference in other parameters was found. Cytogenetic analysis of apoblemas was obtained for 12 cases, and 2 specimens were contaminated. Seven of ten patients had abnormal karyotypes. Conclusion The underlying cause of spontaneous abortion after transferring frozen thawing blastocysts appears to be abnormal karyotypes.Advancing maternal age seems to increase the risk of spontaneous abortion.

    Full Text Available Reproductive health is exquisitely sensitive to characteristics of an individual’s environment including physical, biological, behavioral, cultural and socioeconomic factors. This study was launched to elucidate the effect of the exposure to chemical pollutants as aromatic amines viz. (benzidine, mono-acetyl benzidine, diacetyl benzidine, α,β-naphthylamine as well as the biological pollutants e.g., human cytomegalovirus (HCMV as risk factors for recurrent spontaneous abortion (RSA through determination of MDA as a marker of oxidative stress and determination of some antioxidant markers. The results of the current study revealed that the aborter mothers were being exposed to environmental pollutants as aromatic amines which were manifested by the presence of benzidine, mono-acetyl-benzidine, di-acetyl-benzidine, α,β-naphthylamine in most of their urine samples, where the level of aromatic amines were more 13.6, 10, 15, and 4-folds than the control group, respectively. Also, the data suggest that in early pregnancy failure there is an increase in markers of oxidative stress and a probable decrease in maternal antioxidant defenses (22 nmol/ml and 17 mg/l, 550 U/l, respectively. Generation of ROS in large quantities, in the first trimester placenta which has limited antioxidant defenses may cause DNA damage, oxidation of protein and lipid resulting in extensive cell death. Also, it was demonstrated that high elevation of HCMV inhibits cytotrophoblasts proliferation, migration invasion and matrix metalloproteins (MMP expression. Obviously, placental toxicological responses are partly due to pharmaco/toxico dynamic responses to the chemicals. Conclusively, the aforementioned findings emphasis that, the exposures to environmental chemical and/or biological risk factors are implicated in the pathogenesis of recurrent spontaneous abortion.

    Full Text Available Background: Carriers of structural chromosomal rearrangements such as Robertsonian or reciprocal translocations have an increased risk of spontaneous abortion and producing offspring with genetic abnormalities. Case Report: We report a man with balanced chromosomal translocations located at 6p22, and 7q22. His wife has a history of four spontaneous abortions. Conclusion: Couples with a history of abortions should be investigated cytogenetically, after other causes of miscarriages are excluded. The possibility of spontaneous abortions can be reduced with preimplantation genetic diagnosis (PGD before embryo transfer.

    Research in contraceptive technology, investments in family planning programs, and the availability of safe abortion are essential not only to control population growth and improve the health of mothers and children, but also to improve the status of women. At present, however, it is estimated that 25% of married women in sub-Saharan Africa, 18% in Latin America and the Caribbean, and 13% in Asia, the Middle East, and North Africa have an unmet need for contraception. Without rapid advances in access to family planning, more women will die during this decade from pregnancy, childbirth, and abortion than in any other decade in history. Although the 1994 Cairo Conference achieved consensus on a range of reproductive health issues, strategies for implementing and funding these programs remain undefined.

    To investigate membrane tumor necrosis factor receptor 1 protein expression level in decidua andconcentration of soluble tumor necrosis factor receptor 1 in serum in women with unexplained early spontaneous abortion,threatened abortion, and compare the levels with healthy pregnant women. Methods: Thirty-seven women with unexplainedearly spontaneous abortion, 27 women with threatened abortion, and 34 healthy pregnant women undergoing artificial abortionof pregnancy at 6 - 10 weeks of gestation were selected. Decidual samples were collected when women were undergoing arti-ficial abortion, and blood samples were collected at the same time. The level of membrane tumor necrosis factor receptor 1 indecidua was detected by flow cytometer, and the concentration of soluble tumor necrosis factor receptor 1 in sera was mea-sured with an enzyme-linked immunosorbent assay. Results: The ercentages of membrane tumor necrosis factor receptor 1positive decidual cells were 16.42 ± 7.10 Mean ± SD for women with unexplained early spontaneous abortion and 13.14 ±6.30 for healthy pregnant women ( P < 0.05). Serum oncentration of soluble tumor necrosis factor receptor 1 was signifi-cantly higher in women with unexplained early spontaneous abortion than in healthy pregnant women and in women withthreatened abortion, and no difference was found between healthy pregnant women and women with threatened abortion.Conclusion: Women with unexplained early spontaneous abortion present significantly higher expression of tumor necrosisfactor receptor 1 than healthy pregnant women, suggesting that over-expression of tumor necrosis factor receptor 1 may cont-ribute to the development of early spontaneous abortion.

    A repeated or habitual miscarriage (PSP) is defined as three or more consecutive losses of pregnancy. In the first three months of pregnancy, habitual miscarriages occur in about 1% of pregnant women, out of which 50% are of an unknown etiology. It is believed that among them, the greatest number is the consequence of an inadequate alloimmune response of a women to the pregnancy. The endocrine and immune systems are in a close interaction during the implantation and maintaining of pregnancy. This communication is the most obvious on endometrium of pregnancy decidua. The aim of the study was to identify the number and the subpopulation distribution of the decidual NK cells in the decidua by using an immunohistochemical method. The research included a group of 30 women who had had two spontaneous miscarriages consecutively in the first three months of their pregnancy, while the curettage after the third spontaneous abortion was histopathologically and immunohistochemically analyzed. The control group consisted of 20 women without a problematic reproductive anamnesis, who had had their pregnancy terminated for social reasons. The criteria for the eliminating from the research were the diagnosed uterus anomalies, positive screening on thrombophilia, as well as women suffering from diabetes melitus and the ones with the thyroid gland function disorder. The number and the phenotype structure of the uterus NK cells were significantly different between the decidua of a normal pregnancy and that in PSP. In the decidua in PSP, there were much more NK cells with the phenotype of the peripheral circulation CD57 and CD56dim, while in the decidua of the control group the dominant cells were the typical uNK cell subpopulation CD56bright. The above mentioned results show that the disregulation of the immunocompetent cells of the decidua, by creating an inadequate cytokine milieu, is one of the mechanism of rejecting the semiallogeneic blastocyst.

    The concepts, methods, and problems of measuring spontaneous abortion risk are reviewed. The problems touched on include the process of pregnancy verification, the changes in risk by gestational age and maternal age, and the presence of induced abortions. Methods used in studies of spontaneous...... abortion risk include biochemical assays as well as life table technique, although the latter appears in two different forms. The consequences of using either of these are discussed. It is concluded that no study design so far is appropriate for measuring the total risk of spontaneous abortion from early...... conception to the end of the 27th week. It is proposed that pregnancy may be considered to consist of two or three specific periods and that different study designs should concentrate on measuring the conditional risk within each period. A careful estimate using this principle leads to an estimate of total...

    Nurses working in selected departments of general hospitals in Finland were collected from a central register on health personnel in Finland. Using the Hospital Discharge Register and the Register of Congenital Malformations, case nurses were selected who had had a spontaneous abortion (N = 217) or a malformed child (N = 46) between the years 1973 and 1979. Controls consisted of three nurses who had had a normal birth; the control nurses were matched for age and hospital of employment. Information on exposure in the first trimester of pregnancy was sought through the head nurses of the hospitals. No significant increase in risk of spontaneous abortion or of malformation was observed after exposure to anaesthetic gases (odds ratio for spontaneous abortion 1.2), sterilizing gases and soaps, or x-rays. Handling of cytostatic drugs did not affect the frequency of spontaneous abortion but was associated with malformations in the offspring. The odds ratio, based on eight cases, was 4.7 (p = 0.02) when the logistic model was adopted. The results suggest that the exposures investigated, other than cytostatic drugs, do not cause a strong reproductive risk. Further studies are needed, particularly on cytostatic drugs.

  15. Immunoexpression of CD30 and CD30 ligand in deciduas from spontaneous abortions

    Full Text Available In the present study, using immunohistochemistry, we studied the expression of CD30 and CD30-L in 35 deciduas obtained from women following elective abortion during normal physiological gestation and in 60 deciduas obtained from women after spontaneous abortion with or without signs of inflammation. The main difference was noticed in the first trimester of gestation in which was found a decrease in CD30/CD30-L-positive decidual glandular and stromal cells in a greater number of cases of spontaneous abortions with respect to cases of physiological pregnancies (70% vs 50%, p<0.05. In addition, deciduas from spontaneous abortions with inflammation and without inflammation reacted similarly. The reduced expression of CD30 and CD30-L and their cellular pattern detected in the deciduas from spontaneous abortions suggest that the CD30/CD30-L system is crucial for preventing abortions in the first trimester. And furthermore, the distinctive expression of CD30/CD30- L in deciduas from physiological pregnancies may indicate that the CD30/CD30-L system exerts its main role in the first trimester.

    Human parvovirus B19 is a very common viral infection especially in school-aged children. The infection during pregnancy can affect the fetus due to lack of mother's immunity. Although, there is still no evidence of fetal teratogenic effects with parvovirus B19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. This study was aimed to assess the prevalence of parvovirus B19-specific antibody (IgM) in pregnant women who had a spontaneous abortion. This cross-sectional study was carried out in all pregnant women who referred due to a spontaneous abortion. All demographic information such as age, occupation, and gestational age, last history of abortion, gravity, and presence of children below the age of six was recorded and a blood sample was provided for all the women. Then, the blood samples were tested to assay parvovirus B19-specific antibody (IgM) by EuroImmune ELISA kit. Among 94 pregnant women with the mean age of 28.4 years who had a spontaneous abortion, parvovirus B19 specific antibody (IgM) was detected in 17 participants (18.1%). Meanwhile, 14 women (14.9%) were suspected for presence of the antibody in their blood sample. There was no significant difference between the presence of antibody and age of pregnant women, occupation, gestational age, number of previous abortion, presence of children below the age of six and number of pregnancy. These findings revealed that a high percentage of pregnant women are probably non-immune against parvovirus B19, and also there might be a number of spontaneous abortions in which parvovirus infection caused fetal death.  However, more studies are needed to prove the absolute role of parvovirus B19 in these abortions.

    Full Text Available Introduction & Objective: Nowadays, some studies indicate the adverse effects of exposure to chemicals, especially organic solvents on the reproductive system of females. This study aimed to assess the relationship between spontaneous abortion with occupational exposure to organic solvents in pharmaceutical industry. Materials & Methods: This is a cross-sectional and descriptive-analytical study which was carried out in 2010 in one of the pharmaceutical factories located in the suburbs of Tehran. During the study, married women who were working in the factory laboratory units and were exposed to mixed organic solvents were compared with married women who were working in the packing units of the factory without occupational exposure to organic solvents. Frequency of spontaneous abortion and duration of pregnancy were assessed in both two groups. Collected data were analyzed with the SPSS software using t-test, logistic regression, and chi-square test. Results: In the present study, the frequency of spontaneous abortion in employees with exposure to organic solvents mixture was 10.7%. This study showed that even after adjustment for confounding factors, there was a significant correlation between spontaneous abortion and occupational exposure to organic solvents mixture and this correlation increased with increasing levels of exposure to organic solvents. Moreover, a significant correlation was observed between occupational exposure to mixed organic solvents and waiting time to become pregnant (TTP. Furthermore, this study showed that even after adjustment for confounding variables, shift workers were significantly more affected by spontaneous abortion compared to daytime workers (P < 0.001. Conclusion: According to the results of this study, since there is probability of spontaneous abortion resulting from occupational exposure to various chemicals including organic solvents, review of the status of occupational exposure of workers can be helpful

  20. Abortion.

    If you are pregnant and near 40 years old there is 1/137 chance that your child may have Down's syndrome, or 1/65 chance he will have a physical or mental problem. There are tests that can indicate these problems but they increase the risk of spontaneous abortion. A woman should not be forced to carry an unwanted child, and the needs of childless couples should not be addressed in abortion discussions. The Roe v. Wade case made the distinction of not having to determine when life begins, but when it can be sustained outside the body. The Missouri statute states that human life begins at conception, an unborn child has protectable life interests and the parents of that child have protectable life interests of the unborn child in relation to life, health and its well being. States that are really concerned with the interests of unborn children should improve prenatal care, educate teens on contraception, AIDS, and be concerned about violent behavior and smoking. Voters in Michigan and Arkansas approved a law to stop the use of public funds for abortion, other than saving the mother's life. Pro- choice advocates are concerned that the conservative appointees to the supreme court will reverse the previous decision.

    Full Text Available Context: Bacterial vaginosis (BV is related to the increased risk of miscarriage, preterm labor, and postpartum endometritis. Aims: The aim of this study was to evaluate the association between BV and the history of spontaneous abortion and recurrent pregnancy losses. We also examined periods of gestation, including the first and second trimester miscarriages. Materials and Methods: The study population consisted of 200 fertile women. Sixty one (30.5% of 200 women had the history of a spontaneous abortion in the last six months (N = 30 and at least three recurrent pregnancy losses (N = 31. BV was diagnosed either by using Papanicolaou staining, Gram staining, or by culturing with BV-associated bacteria, Gardnerella vaginalis. Results: The presence of BV was statistically associated with the history of a spontaneous abortion in the last 6 months (P 0.05. These women were also evaluated in view of periods of gestation. Forty-seven (77% of 61 women had first trimester miscarriage (≤12 weeks and 14 (23% of 61 women had second trimester miscarriage (>12 weeks. There was a statistically significant relationship between BV and second trimester miscarriage (P 0.05. Conclusion: BV may contribute to spontaneous abortion and second trimester miscarriage.

    This study investigated the relationship between job type and the risk for spontaneous abortion to assess the reproductive toxicity of female workers in the semiconductor industry. A questionnaire survey was administered to current female workers of two semiconductor manufacturing plants in Korea. We included female workers who became pregnant at least 6 months after the start of their employment with the company. The pregnancy outcomes of 2,242 female workers who experienced 4,037 pregnancies were investigated. Personnel records were used to assign the subjects to one of three groups: fabrication process workers, packaging process workers, and clerical workers. To adjust for within-person correlations between pregnancies, a generalized estimating equation was used. The logistic regression analysis was limited to the first pregnancy after joining the company to satisfy the assumption of independence among pregnancies. Moreover, we stratified the analysis by time period (pregnancy in the years prior to 2008 vs. after 2009) to reflect differences in occupational exposure based on semiconductor production periods. The risk for spontaneous abortion in female semiconductor workers was not significantly higher for fabrication and packaging process workers than for clerical workers. However, when we stratified by time period, the odds ratio for spontaneous abortion was significantly higher for packaging process workers who became pregnant prior to 2008 when compared with clerical workers (odds ratio: 2.21; 95% confidence interval: 1.01-4.81). When examining the pregnancies of female semiconductor workers that occurred prior to 2008, packaging process workers showed a significantly higher risk for spontaneous abortions than did clerical workers. The two semiconductor production periods in our study (prior to 2008 vs. after 2009) had different automated processes, chemical exposure levels, and working environments. Thus, the conditions prior to 2008 may have increased the

    Morphologic changes in the placental barrier in spontaneous early abortions under the maternal-embryonic immune conflict, and the role of maternal immunoglobulins (Igs) in these changes. We examined chorionic villi and other tissues obtained from 54 aborts between weeks 3.5 and 8 of pregnancy. Material was divided into two groups. Group 1 (control) contained 15 medically recommended and spontaneous early aborts with no signs of inflammations or pathologic immune processes. Group 2 contained 39 spontaneous early aborts with acute chorionic villitis. Immunohistochemical and morphometric methods were used to study the Igs, different types of immunocompetent cells, and apoptosis-related components of the placental barrier. Acute villitis was found to be characterized by the destruction of all components of the chorionic villi, thrombovasculitis with apoptosis of the endothelium of capillaries and erythroblasts, mucous swelling of the basal membrane, and coagulation of the blood proteins. Due to destruction of the capillaries, the number of avasculate villi increased, and the average number of capillaries per villus decreased. The extremely high number of phagolysosomes with IgG and IgA in the villous monocytes in the group 2 indicates an increase in the phagocytic activity of monocytes against maternal Igs and may reflect the presence of mother-embryo immune conflict. Apoptosis of monocytes and a high number of promonocytes were seen accompanied by a high concentration of p53 protein. A large disturbance in the trophoblast occurred with disappearance of bcl-2 and the appearance of Fas ligand. Massive destruction of maternal Igs in embryonic monocytes and acute villitis in the placental barrier are manifested during the mother-embryo immune conflict, and this may be one of the reasons of spontaneous early abortions.

    Objective:To analyze and investigate the change state of T, B lymphocyte subsets and Th1/Th2 indexes of patients with recurrent spontaneous abortion. Methods: A total of 92 patients with recurrent spontaneous abortion in our hospital from June 2013 to July 2015 were selected as the observation group and 92 women with health delivery history at the same time were selected as the control group,then the peripheral blood T, B lymphocyte subsets and Th1/Th2 indexes of two groups were detected and compared and the peripheral blood T, B lymphocyte subsets and Th1/Th2 indexes of patients with different gestational age at abortion and abortion times were compared too. Results:The peripheral blood T, B lymphocyte subsets and Th1/Th2 indexes of observation group and control group all had obvious differences,and those blood indexes levels' differences of patients with different gestational age at abortion and abortion times were obvious too, all P<0.05 and the differences were significant. Conclusions: The T, B lymphocyte subsets and Th1/Th2 indexes of patients with recurrent spontaneous abortion show abnormal state and the differences of detection results of patients with different gestational age at abortion and abortion times are relatively obvious,so those indexes should be monitored and improved intentinonally.

    Objectives Pregnancy loss in women suffering from hyperthyroidism has been described in case reports, but the risk of pregnancy loss caused by maternal hyperthyroidism in a population is unknown. We aimed to evaluate the association between maternal hyperthyroidism and pregnancy loss in a population-based cohort study. Study Design All pregnancies in Denmark from 1997 to 2008 leading to hospital visits (n = 1,062,862) were identified in nationwide registers together with information on maternal hyperthyroidism for up to 2 years after the pregnancy [hospital diagnosis/prescription of antithyroid drug (ATD)]. The Cox proportional hazards model was used to estimate adjusted hazard ratio (aHR) with 95% confidence interval (CI) for spontaneous abortion (gestational age hyperthyroidism was diagnosed before/during the pregnancy (n = 5,229), spontaneous abortion occurred more often both in women treated before the pregnancy alone [aHR 1.28 (95% CI 1.18-1.40)] and in women treated with ATD in early pregnancy [1.18 (1.07-1.31)]. When maternal hyperthyroidism was diagnosed and treated for the first time in the 2-year period after the pregnancy (n = 2,361), there was a high risk that the pregnancy under study had terminated with a stillbirth [2.12 (1.30-3.47)]. Conclusions Both early (spontaneous abortion) and late (stillbirth) pregnancy loss were more common in women suffering from hyperthyroidism. Inadequately treated hyperthyroidism in early pregnancy may have been involved in spontaneous abortion, and undetected high maternal thyroid hormone levels present in late pregnancy may have attributed to an increased risk of stillbirth.

    The aim of this trial was to investigate the efficacy of massive i.v. immunoglobulin (MIVIg) treatment for women with a history of recurrent spontaneous abortion (RSA) due to unexplained aetiology. The study included nine women (11 pregnancies) with a history of four or more consecutive RSA with unexplained aetiology and no live births. The mean number of fetal losses was 4.5 (range 4-6 abortions). Over the course of 5 days, immunoglobulin (20 g/day) was infused i.v. at gestational weeks 4-7. No additional infusions were carried out. Two pregnancies out of the 11 conceptions resulted in missed abortions at gestational weeks 6 and 7 respectively. Mosaicism (46XX/ 48XX, +16, +20), and tetraploidy (92XXXX) were found by chromosome analyses of the two aborti. Eight out of the other nine pregnancies resulted in full term deliveries of healthy neonates. One pregnancy developed intrauterine growth retardation and fetal distress, resulting in a premature delivery (30 gestational weeks) by Caesarean section. Thus, excluding the two abortions with chromosome aberrations, the MIVIg treatment was effective in all nine pregnancies of RSA women with unexplained aetiology. This MIVIg treatment (100 g administered in early gestation) may be a beneficial alternative to previous IVIg infusion methods, and should be further evaluated in a multicentric, placebo-controlled study, employing a larger number of homogeneous patients who fall into a high risk category of first trimester abortions.

    Full Text Available Varicocele is still an enigma. Its effects on semen analysis, fertility and, more re-cently, early ejaculation and spontaneous abortion in spouses are not yet fully understood. In this retrospective study, we evaluated these four parameters (semen analysis, fertility, early ejacu-lation and spontaneous abortion among spouses in relation to varicocele and varicocelectomy during a 13-year period. A total of 1,711 patients with varicocele underwent varicocelectomy by high inguinal method (251 cases, subinguinal method (1,375 cases, scrotal method (34 cases, and subinguinal method with local anesthesia (38 cases. Our complication rate was acceptable. Sperm count, motility and morphology increased three months post operation in 55, 51, and 46%, respectively (P value 0.000, 0.000, and 0.015, respectively. Paternity was 56% after one year of post varicocelectomy follow-up. Only 7 out of 82 azoospermic men had sperm in their semen after varicocelectomy and only one of them with mild spermatogenic hypoplasia became a father. The spontaneous abortion rate in the spouses of respondents was 59%. Early ejaculation improved in 75% of the respondents. In conclusion, varicocelectomy does not improve sperm parameters in all men, but it improves pregnancy rate, early ejaculation, and scrotal pain.

    Arsenic is an abundant toxicant in ground water and soil around areas with extractive industries. Human epidemiological studies have shown that arsenic exposure is linked to developmental defects and miscarriage. The placenta is known to utilize vasculogenesis to develop its circulation. The hypothesis tested here states the following: arsenic exposure causes placental dysmorphogenesis and defective placental vasculogenesis resulting in placental insufficiency and subsequent spontaneous abortion. To test this hypothesis, pregnant mice were exposed to sodium arsenite (AsIII) through drinking water from conception through weanling stages. Neonatal assessment of birth rates, pup weights, and litter sizes in arsenic exposed and control mothers revealed that AsIII-exposed mothers had only 40% the fecundity of controls. Preterm analysis at E12.5 revealed a loss of fecundity at E12.5 from either 20 ppm or greater exposures to AsIII. There was no loss of fecundity at E7.5 suggesting that spontaneous abortion occurs during placentation. Histomorphometry on E12.5 placentae from arsenic-exposed mice revealed placental dysplasia especially in the vasculature. These results suggest that arsenic toxicity is causative for mammalian spontaneous abortion by virtue of aberrant placental vasculogenesis and placental insufficiency.

    A study was conducted to determine whether the incidence of spontaneous abortion was greater than expected near the Three Mile Island (TMI) nuclear power plant during the months following the March 28, 1979 accident. All persons living within five miles of TMI were registered shortly after the accident, and information on pregnancy at the time of the accident was collected. After one year, all pregnancy cases were followed up and outcomes ascertained. Using the life table method, it was found that, given pregnancies after four completed weeks of gestation counting from the first day of the last menstrual period, the estimated incidence of spontaneous abortion (miscarriage before completion of 16 weeks of gestation) was 15.1 per cent for women pregnant at the time of the TMI accident. Combining spontaneous abortions and stillbirths (delivery of a dead fetus after 16 weeks of gestation), the estimated incidence was 16.1 per cent for pregnancies after four completed weeks of gestation. Both incidences are comparable to baseline studies of fetal loss.

    2000-01-01

    To investigate the relationship between inducible nitric oxide synthase (iNOS) and the early spontaneous abortion. , in situ hybridization and immunohistochemistry were used to detect the expression of iNOS in trophoblasts in the early pregnancy with and without spontaneous abortion (group Ⅰ and group Ⅱ ). By light microscopy and computer color magic image analysis system (CMIAS), light density (D) and the positive cell number per statistic square (N/S) in situ hybridization were used to analyze the positive cell index, while total positive cells (N) and the positive unit (Pu) were used in immunohistochemistry. By in situ hybridization, D and N/S in trophoblasts were 0. 35±0. 028, 0. 07±0. 011 respectively in group Ⅰ and 0. 18±0. 016,0. 015±0. 003 in group Ⅱ . In terms of immunohistochemical staining, N and Pu were 0. 058±±0. 007, 11. 94±2. 01 in group Ⅰ and 0. 013±0. 009, 1. 08±0. 35 in group Ⅱ in trophoblasts. Significant differences existed between two groups. It is concluded that the higher nitric oxide produced by the higher expression of iNOS in trophoblasts might play an important role in the early spontaneous abortion.

    Full Text Available Bovine Herpesvirus type 5 (BoHV-5 has not been conclusively demonstrated to cause bovine abortion. Brain lesions produced by Neospora caninum and Bovine Herpesvirus type 1 (BoHV-1 exhibit common features. Therefore, careful microscopic evaluation and additional diagnostic procedures are required to achieve an accurate final etiological diagnosis. The aim of the present work was to investigate the occurrence of infections due to BoHV-1, BoHV-5 and N. caninum in 68 cases of spontaneous bovine abortions which showed microscopic lesions in the fetal central nervous system. This study allowed the identification of 4 (5.9% fetuses with dual infection by BoHV-5 and N. caninum and 33 (48.5% cases in which N. caninum was the sole pathogen identified. All cases were negative to BoHV-1. The results of this study provide evidence that dual infection by BoHV-5 and N. caninum occur during pregnancy in cattle; however, the role of BoHV-5 as a primary cause of bovine abortion needs further research. Molecular diagnosis of BoHV-5 and N. caninum confirmed the importance of applying complementary assays to improve the sensitivity of diagnosing bovine abortion.

    Photoperiod-sensitive genic male-sterile (PSGMS) rice (Oryza sativa L.), a natural mutant found in the rice cultivar Nongken 58, is very useful for the development of hybrid rice cultivars. Despite its widespread use in breeding programs, the initial stage of the abortive development of PSGMS rice and the possible cytological mechanisms of pollen abortion have not been determined. In the present study, a systematic cytological comparison of the anther development of PSGMS rice with its normal fertile counterpart is conducted. The results show that pollen abortion in PSGMS rice first occurs before the pollen mother cell (PMC) stage, and continues during the entire process of pollen development until pollen degradation. The abortive process was closely associated with the abnormal behavior of the tapetum. Although tapetum degeneration in PSGMS rice initiates already at the PMC stage, it proceeds slowly and does not complete until the breakdown of the pollen. Such cytological observations were supported by the results of the TUNEL (TdT-mediated dUTP Nick End Labeling) assay, which detects DNA fragmentation resulting from programmed cell death (PCD), indicating that the premature tapetum degeneration is in the process of PCD.

    BACKGROUND: Consumption of caffeine and alcohol is suspected to affect pregnancy outcome. Use of both stimulants is widespread and even minor effects on fetal viability are of public health interest. METHODS: We performed a nested case-control study using prospective data from a population.......72 (1.00-2.96) for a pre-pregnancy intake on 75-300, 301-500, 501-900 and >900 mg caffeine per day respectively (P = 0.05 for trend). A pre-pregnancy intake of alcohol was not a predictor for spontaneous abortion. CONCLUSIONS: A high intake of caffeine prior to pregnancy seems to be associated......-based cohort comprising 11088 women aged 20-29 years. From this cohort, women who experienced either a spontaneous abortion (n = 303) or who gave birth (n = 1381) during follow-up [mean time: 2.1 years (range: 1.6-3.4)] were selected. Associations between self-reported exposures to caffeine and/or alcohol...

  19. Methylenetetrahydrofolate reductase and transcobalamin genetic polymorphisms in human spontaneous abortion: biological and clinical implications

    2004-02-01

    Full Text Available Abstract The pathogenesis of human spontaneous abortion involves a complex interaction of several genetic and environmental factors. The firm association between increased homocysteine concentration and neural tube defects (NTD has led to the hypothesis that high concentrations of homocysteine might be embryotoxic and lead to decreased fetal viability. There are several genetic polymorphisms that are associated with defects in folate- and vitamin B12-dependent homocysteine metabolism. The methylenetetrahydrofolate reductase (MTHFR 677C>T and 1298A>C polymorphisms cause elevated homocysteine concentration and are associated with an increased risk of NTD. Additionally, low concentration of vitamin B12 (cobalamin or transcobalamin that delivers vitamin B12 to the cells of the body leads to hyperhomocysteinemia and is associated with NTD. This effect involves the transcobalamin (TC 776C>G polymorphism. Importantly, the biochemical consequences of these polymorphisms can be modified by folate and vitamin B12 supplementation. In this review, I focus on recent studies on the role of hyperhomocysteinemia-associated polymorphisms in the pathogenesis of human spontaneous abortion and discuss the possibility that periconceptional supplementation with folate and vitamin B12 might lower the incidence of miscarriage in women planning a pregnancy.

    The Weathering Effect is a theory that links stress exposure, over the life-course, with racial disparities in reproductive outcomes, through the effects of social adversity on a woman's body. The concept of maternal "weathering" captures cumulative somatic and psychological adversities that can exacerbate the effects of aging. Much of the evidence for weathering comes from observational studies linking self-report measures with reproductive outcomes. The purpose of this review is to explore biological mechanisms that underlie these observations. We focus on spontaneous abortion because this event is understudied despite evidence of racial disparities in this outcome. Spontaneous abortion is the most common pregnancy failure, and it happens early in pregnancy. Early pregnancy is a time most susceptible to the harmful effects of immune dysregulation that may, in part, result from adversities experienced before pregnancy begins. In exploring these mechanisms, we draw on well-defined signaling processes observed in the stressor-depression relationship. Pro-inflammatory dysregulation, for example, has particular relevance to immunological control occurring early in pregnancy. Early pregnancy immunologic changes affect the trajectories of pregnancy via control of trophoblastic invasion. Within the first few weeks of pregnancy, uterine derived cytokines operate within cytokine networks and play a critical role in this invasion. Programming for pro-inflammatory dysregulation can occur before conception. This dysregulation, brought into early pregnancy, has implications for viability and success of the index pregnancy. These patterns suggest early pregnancy health is susceptible to stress processing pathways that influence this immunologic control in the first six to eight weeks of pregnancy. In this review, we discuss the known mediating role of immune factors in the stressor-depression relationship. We also discuss how adversity experienced before the index pregnancy, or

    Objective To investigate the aberrant expressions of TNF-α and TGF-β1 in peripheral blood mononuclear cells (PBMCs) and placental tissues in patients with early spontaneous abortionMethods Using the technique of semi-quantitative reverse transcript-polymerase chain reaction (RT-PCR), TNF-α mRNA and TGF-β1 mRNA in PBMCs were measured in spontaneous abortion group (30 cases), normal pregnancy group (25 cases) and nonpregnant group (25 cases). The expressive intension of TNF-α protein and TGF-β1 protein in placental tissues was also identified by immunohistochemistry.Results Both levels of TNF-α mRNA and TGF-β1 mRNA expressed in PBMCs were significantly different between the three groups respectively (P<0. 05). Levels of TNF-α in syncytiotrophoblastic and cytotrophoblastic cells of the two aborted groups were substantially higher than those of the non-pregnant group (P<0. 01), but the levels of TGF-β1 in syncytiotrophoblastic cells of the two aborted groups were markedly lower than those of the non-pregnant group (P<0. 01).Conclusion There is potential relation between TGF-β1 at the fetomaternal interface and spontaneous abortion. TGF-β1 may contribute to the maintenance of pregnancy,and low-level expression of TGF-β1 may be associated with pregnancy failure.

  2. Oxidative Stress and Aberrant Programmed Cell Death Are Associated With Pollen Abortion in Isonuclear Alloplasmic Male-Sterile Wheat

    Full Text Available Cytoplasmic male sterility is crucial for the utilization of hybrid heterosis and it possibly occurs in parallel with tapetal programmed cell death (PCD and oxidative metabolism responses. However, little is known about the mechanisms that underlie pollen abortion in wheat. Therefore, we obtained two isonuclear alloplasmic male sterile lines (IAMSLs with Aegilops kotschyi and Ae. juvenalis cytoplasm. Compared with the maintainer line, cytochemical analyses of the anthers demonstrated that the IAMSLs exhibited anomalous tapetal PCD and organelles, with premature PCD in K87B1-706A and delayed PCD in Ju87B1-706A. We also found that the dynamic trends in reactive oxygen species (ROS were consistent in these two IAMSLs during anther development and they were potentially associated with the initiation of tapetal PCD. In addition, the activities of ROS-scavenging enzymes increased rapidly, whereas non-enzymatic antioxidants were downregulated together with excess ROS production in IAMSLs. Real-time PCR analysis showed that the expression levels of superoxide dismutase, catalase, and ascorbate peroxidase genes, which encode important antioxidant enzymes, were significantly upregulated during early pollen development. Thus, we inferred that excessive ROS and the abnormal transcript levels of antioxidant enzyme genes disrupted the balance of the antioxidant system and the presence of excess ROS may have been related to aberrant tapetal PCD progression, thereby affecting the development of microspores and ultimately causing male sterility. These relationships between the mechanism of PCD and ROS metabolism provide new insights into the mechanisms responsible for abortive pollen in wheat.

    Objective: To explore the relationship between recurrent spontaneous abortion (RSA) and anti-β 2 - glycoprotein I (anti-β 2 -GP I) antibody. Methods: The levels of anti-β 2 -GP I antibody in serum from 81 RSA patients and 39 normal women were detected by ELISA. Results: The positive rate of anti-β 2 -GP I in RSA patients (42.0%) was obviously higher than that in normal women (7.7 %) (P 2 -GP I IgG in statistics between RSA patients (40.8%) and normal women (7.7%) (P 2 -GP I IgM in statistics between RSA patients and normal women (P>0.05). There was no difference of the positive rate of anti-β 2 -GP I in statistics between early and late, as well as between 2 times and more than 2 times abortions of RSA (P>0.05). Conclusion: The anti-β 2 -GP I antibody is related to RSA, and it may be regarded as a immunological assistant diagnostic index for RSA. (authors)

    Full Text Available Although a history of first-trimester recurrent spontaneous abortion (FRSA is regarded as a risk factor in antenatal care, the characteristic of subsequent pregnancy outcome is not clearly elucidated. Here, a retrospective analysis was performed on the clinical data of 492 singleton pregnant women. 164 of them with the history of FRSA were enrolled in study group, compared to 328 deliveries without the history of FRSA. For maternal outcomes, patients in the study group delivered earlier with mean gestational age and the incidences of cesarean section and postpartum hemorrhage were higher compared to the control group. For placental outcomes, the incidence of placenta-mediated pregnancy complications (PMPC in the study group increased in terms of late-onset preeclampsia, oligohydramnios, early-onset fetal growth restriction, and second-trimester abortion. Patients in the study group were more likely to suffer from placenta accreta, placenta increta, and placenta percreta. For perinatal outcomes, the proportion of birth defects of newborns in the study group was greater. At last, logistic regression analyses showed that the history of FRSA was an independent risk factor for cesarean section and pregnancy complications. In conclusion, women with the history of FRSA are often exposed to an elevated incidence of maternal-placental-perinatal adverse pregnancy outcomes.

    Infection with parvovirus B19 may cause fetal losses including spontaneous abortion, intrauterine fetal death and non-immune hydrops fetalis. The aim of this study is to determine the frequency of parvovirus B19 in formalin fixed placental tissues in lost fetuses using real-time PCR method. In this cross-sectional study, 100 formalin fixed placental tissues with unknown cause of fetal death were determined using real-time PCR method after DNA extraction. Six out of 100 cases (6%) were positive for parvovirus B19 using real-time PCR. Gestational age of all positive cases was less than 20 weeks with a mean of 12.3 weeks. Three cases have a history of abortion and all of positive cases were collected in spring. Mean age of positive cases were 28 years. Parvovirus B19 during pregnancy can infect red precursor cells and induces apoptosis or lyses these cells that resulting in anemia and congestive heart failure leading to fetal death. Management of parvovirus B19 infection in pregnant women is important because immediate diagnosis and transfusion in hydropsic fetuses can decrease the risk of fetal death.

    The New York State Department of Health was asked in September 1978 of investigate a cluster of leukemias and lymphomas in a rural town in western New York State of less than 1,000 people. Four cases of these diseases had been diagnosed in the town's population in the previous 10 months. Residents were concerned about environmental hazards such as background radiation and contamination of their water supply. A total environmental study of the area was not feasible or warranted, but certain environmental studies of the area were conducted. No environmental health hazards were identified. Incidence rates for towns in the four-county area (population 281,000) surrounding the study town were analyzed, based on data from the New York State Cancer Registry. These four counties had been severely affected by the flood following the 1972 Hurricane Agnes. Examination of annual leukemia and lymphoma incidence rates for these counties for 1966--77 revealed that the rates for towns in the river valley (population 102,000), but not for nonriver-valley towns, were 20 to 50 percent above the statewide rates for 1972--77. All other cancer rates remained level throughout both periods. An analysis of spontaneous abortion rates for the four counties for 1968--77 showed a significant peak in 1973, but not for the rest of upstate New York. The peak was concentrated in the towns in the river valley. The apparent time-space cluster of leukemias and lymphomas in conjunction with a marked increase in the spontaneous abortion rate suggests an unidentified flood-related environmental exposure

    Abortion is the interruption of a dynamic process in a final and irreversible form. The legalization of abortion is applied to human ontogenesis, that is, the development of the human being. However, the embryo that is growing in the uterus is not a human being because a human being is a complex organism with differentiated systems, its own identity and intrinsic autonomy in its process of development. There are basically four levels of the analysis of the problem of abortion: 1) fundamental emotional arguments; 2) profound ignorance of technical and scientific facts; 3) rational positions obfuscated by the dramatic intensity of everyday situations; and 4) the conjunction of deliberated position where culpability is avoided with solidarity for all subjects of the process with a socially oriented view. The phenomenon of abortion from an epidemiological point of view summons the facts with which it is associated: poverty, illiteracy, shortage or lack of community health resources, absence of centers for adolescents, degradation of the environment, and precariousness of employment.

    Recurrent spontaneous abortion (RSA) is defined as three or more consecutive abortions before the 20th week of gestation. There is increasing evidence to support an immunological mechanism for the occurrence of RSA. The purpose of our study was to examine whether single-nucleotide polymorphisms (SNPs) of the interleukin-4 receptor gene IL4R influence susceptibility to, recurrent spontaneous abortion. This is a case-control study. We recruited 200 patients with RSA (case group) using established diagnostic criteria and 200, normal individuals (control group) at the fertility and infertility center in Yazd city and Isfahan city during 2012 to 2013. We screened the I50V variant in IL-4R in patients and controls by PCR-RFLF method, and we performed an association analysis between I50V variant and RSA.the data was analyzed by spss 16 software using Chi-square test. No differences in the genotype and allele frequencies of the I50V SNPs were identified between patients with RSA and healthy controls. The frequency of SNP in IL-4 receptor (I50V) in patients with recurrent spontaneous abortion did not differ significantly compared with the control group. Analysis of IL4R SNP haplotypes or complex alleles suggested no dominant protection in patients with RSA.

    Insulin resistance (IR) has been reported to play an important role in recurrent spontaneous abortion (RSA) among patients with polycystic ovary syndrome (PCOS). However, scanted materials exist regarding the independent effect of IR on RSA. The aim of this study is to investigate the status of IR in first trimester pregnant patients with normal pre-pregnant glucose tolerance and history of RSA. This two-center case-control study enrolled totally 626 first trimester pregnant women including 161 patients with a history of recurrent spontaneous abortion, who were pre-pregnantly glucose-tolerant according to oral glucose tolerance test (OGTT), and 465 women with no history of abnormal pregnancies of any kind. Clinical, biochemical and hormonal parameters were simultaneously measured in all participants. Serum beta-HCG, estradiol, progesterone, fasting plasma glucose and fasting plasma insulin levels, as well, the calculated homeostasis model assessment of insulin resistance index (HOMA-IR), fasting plasma glucose/insulin ratio(G/I) and pregnancy outcome were analyzed and compared. Serum beta-HCG and progesterone were found to be significantly lower in RSA group compared to controls. Subjects in RSA group were found to have higher HOMA-IR and lower G/I ratio than those in control group. Serum beta-HCG and progesterone were negatively correlated with HOMA-IR, and positively with G/I ratio even after adjustment for BMI. The spontaneous abortion rate within first trimester pregnancy of RSA patients was significantly higher than that in controls. In conclusion, woman with recurrent spontaneous abortion and normal pre-pregnant glucose metabolism tends to be more insulin resistant during first trimester pregnancy than healthy controls, no matter whether she has PCOS or not. Insulin resistance might be one of the direct causes that lead to recurrent abortion.

    Having read Professor Peter Huntingford's letter (25 August, p 496), I am more convinced than ever that reduction to the simplest possible terms will always clarify an issue, and I am at one with him in deploring the terms "serious," "grave," and "substantial." His last paragraph approximates to such clarify when he says "the right of women to choose freely whether or not they bear a child"--but I fear that the phrase is slanted and ignores an essential ingredient in the abortive act. Whereas the secondary effect of abortion is certainly that the woman will not bear a child, the primary effect is the killing of that child, admittedly small and defenceless. Maybe there are many who will seek to justify the killing of their fellow members of the human race on the grounds that they are not wanted, or might be handicapped; if so, let them proclaim these views "in good set terms." But if the principle of getting rid of the unwanted by killing them is to expand its application further, who among us will be safe when someone else can decide our fate? Even the advocates of euthanasia usually insist that it be voluntary. Who yet has asked a fetus whether it wants to live or be killed?

    A major cause of spontaneous abortions is chromosomal abnormality of foetal cells. We report the generation of an induced pluripotent stem cell line from the fibroblasts isolated from chorionic villi of an early spontaneously aborted foetus with Turner syndrome. The Turner syndrome villus induced pluripotent stem cell line is transgene free, retains the original XO karyotype, expresses pluripotency markers and undergoes trilineage differentiation. This pluripotent stem cell model of Turner syndrome should serve as a tool to study the developmental abnormalities of foetus and placenta that lead to early embryo lethality and profound symptoms like infertility in 45 XO survivors.

    To determine the origin of the extra chromosome in trisomy 8 in spontaneous abortions. We analyzed 4 cases of nonmosaic trisomy 8 in 1st-trimester spontaneous abortions and their parents with DNA polymorphism analysis using microsatellite DNA markers. In 3 cases the extra chromosome was maternal in origin and in 1 case paternal in origin. In 2 of the cases the nondisjunction had occurred in maternal meiosis, while the other 2 cases were consistent with a postzygotic (mitotic) origin of the additional chromosome. Although a small number of cases studied, these results suggest differences from the common autosomal trisomies 21, 18, 16, and 13 where the vast majority of cases are due to errors in maternal meiosis.

    The UK Health and Safety Executive (HSE) conducted a study to examine the risk of spontaneous abortion (SAB) in British female semiconductor industry workers, following reports from the USA which suggested an association between risk of SAB and work in fabrication rooms and/or exposure to ethylene glycol ethers. A nested case-control study based on 2,207 women who had worked at eight manufacturing sites during a 5-year retrospective time frame was established; 36 cases were matched with 80 controls. The overall SAB rate in the industry was 10.0%. (65 SABs/651 pregnancies) The crude odds ratio (OR) for fabrication work was 0.65 (95% CI 0.30-1.40). This was essentially unchanged after adjustment for a range of potential confounding factors in the first 3 months of pregnancy and was reduced to 0.58 (95% CI 0.26-1.30) after adjustment for smoking in the previous 12 months. There were no statistically significantly elevated ORs for any work group or any specific chemical or physical exposure in the industry. There is no evidence of an increased risk of SAB in the British semiconductor industry. Am. J. Ind. Med. 36:557-572, 1999. Published 1999 Wiley-Liss, Inc.

    Full Text Available BACKGROUND: Studies on the risk of chromosomal abnormalities in early spontaneous abortion after assisted reproductive technology (ART are relatively controversial and insufficient. Thus, to obtain a more precise evaluation of the risk of embryonic chromosomal abnormalities in first-trimester miscarriage after ART, we performed a meta-analysis of all available case-control studies relating to the cytogenetic analysis of chromosomal abnormalities in first-trimester miscarriage after ART. METHODS: Literature search in the electronic databases MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL based on the established strategy. Meta-regression, subgroup analysis, and Galbraith plots were conducted to explore the sources of heterogeneity. RESULTS: A total of 15 studies with 1,896 cases and 1,186 controls relevant to the risk of chromosomal abnormalities in first- trimester miscarriage after ART, and 8 studies with 601 cases and 602 controls evaluating frequency of chromosome anomaly for maternal age≥35 versus <35 were eligible for the meta-analysis. No statistical difference was found in risk of chromosomally abnormal miscarriage compared to natural conception and the different types of ART utilized, whereas the risk of fetal aneuploidy significantly increased with maternal age≥35 (OR 2.88, 95% CI: 1.74-4.77. CONCLUSIONS: ART treatment does not present an increased risk for chromosomal abnormalities occurring in a first trimester miscarriage, but incidence of fetal aneuploidy could increase significantly with advancing maternal age.

    We tested whether antihistamine exposure during early pregnancy is associated with spontaneous abortion (SAB) or preterm birth (PTB). Women were enrolled in Right from the Start (2004-2010), a prospective pregnancy cohort. Data about first-trimester antihistamine use were obtained from screening and first-trimester interviews. Self-reported outcomes included SAB and PTB and were verified by medical records. Cox proportional hazards models were used to test for an association between antihistamine use and each outcome, both performed adjusting for confounders. Among the 2685 pregnancies analyzed, 14% (n = 377) reported use of antihistamines. Among antihistamine users, 12% (n = 44) experienced SABs, and 6% (n = 21) had PTBs. Antihistamine exposure was not associated with SAB (adjusted hazard ratio [aHR] = 0.88, 95% confidence interval [CI] 0.64, 1.21) or PTB, which was modified by maternal race (aHR = 1.03, 95%CI 0.61, 1.72 among White women and aHR = 0.43, 95%CI 0.14, 1.34 among Black women). Despite the biologic plausibility that antihistamine use may influence pregnancy outcomes, we did not detect evidence of an association with SAB or PTB. These data demonstrate the utility of large prospective cohorts for evaluating drug safety in pregnancy when concerns are raised from animal models. Copyright © 2014 John Wiley & Sons, Ltd.

    Human leukocyte antigen-E (HLA-E)is a non-classical major histocompatibility complex (MHC) class I antigens which expressed on extra villous cytotrophoblast, which interacts with NKG2A, is an inhibitory receptor on natural killer (NK) cells and leading to down regulation of immune response in the maternal-fetal interface and provides maternal immune tolerance of the fetus. This study was designated to investigate the gene frequencies of E0101 and E0103 in HLA-E gene in Iranian women with recurrent spontaneous abortion (RSA). Amplification Refractory Mutation System (ARMS-PCR) technique was carried out to detect polymorphism in exon 3 of the HLA-E gene in women with RSA and controls (n=200). Differences between groups were analyzed by SPSS19 software using (2) test. There was no significant difference in the allele frequencies of the HLA-E polymorphism between RSA and fertile controls but HLA-E 0101/0103 heterozygous genotype was found to be significantly higher in RSA group (p=0.006, OR=1.73), so this genotype might confer susceptibility to RSA. Our results suggest that HLA-E 0101/0103 heterozygous genotype leads to increase of RSA risk. It seems that by genotyping of HLA-E polymorphism, we can predict the risk of RSA in infertile women.

    . Conclusão: para uma investigação completa dos fatores associados ao aborto espontâneo recorrente faz-se necessária a inclusão do fator aloimune, sem a qual a maior parte dos casos não terá etiologia esclarecida.Purpose: to identify recurrent spontaneous abortion- associated factors. Subjects: one hundred seventy-five outpatients were investigated from March 1993 to March 1997 at the "Ambulatório de Aborto Recorrente CAISM/UNICAMP". All of them had had three or more consecutive spontaneous abortions and/or two abortions and were 35 years or more old. Methods: the investigation protocol included: couple's karyotype; hysterosalpingography, serial plasma progesterone levels and/or endometrial biopsy; toxoplasmosis, listeriosis, brucelosis, lues and cytomegalovirus serum tests; Chlamydia trachomatis and Mycoplasma hominis cultures of cervical discharge; TSH and thyroid hormone levels; fasting glucose; autoantibody panel, anti-HLA antibody search by microlymphocytotoxicity crossmatch and one-way mixed lymphocyte culture with inhibitor factor detection. Husband's evaluation included: physical evaluation, lues, Chagas' disease, B and C hepatitis and AIDS serum tests, microlymphocytotoxicity crossmatch and one-way mixed lymphocyte culture with inhibitor factor detection. Results: alloimmune etiology was the most frequently found factor (86.3% of studied patients, represented by negative crossmatch and one-way mixed lymphocyte culture with inhibitor factor below 50%. The second most frequently found factor was cervical incompetence (22.8%, followed by hormonal factor (21.2%, mainly represented by luteal insufficiency. Some patients were found to have more than one etiologic factor. Conclusion: the investigation of recurrent spontaneous abortion-associated factors must include alloimmune etiology. Most cases will remain unexplained without this investigation.

    Living in areas with high air pollution may have adverse effects on human health. There are few studies about the association between breathing polluted air and adverse pregnancy outcomes in the Middle East. The aim of this study was to determine the relationship between air pollution and spontaneous abortion, premature birth, and stillbirth in Ahvaz. A time-series study was conducted. Data about spontaneous abortion, premature deliveries, and stillbirth was collected from Ahvaz Imam Khomeini Hospital. Air pollution data including NO, CO, NO 2 , PM 10 , SO 2 , O 3 , and climate data were, respectively, collected from the Environmental Protection Agency and the Khuzestan Province Meteorology Office from March 2008 until March 2015. The relationship between air pollutants with the number of abortions, premature births, and stillbirths was found using a quasi-Poisson distributed lag model, adjusted by trend, seasonality, temperature, relative humidity, weekdays, and holidays. The average daily dust in Ahvaz on 7.2% days of the year was higher than 500 μg/m 3 (very dangerous). Findings from this study indicate a significant association between each 10-unit increase in SO 2 and spontaneous abortion in lag 0 and 9 days. There was a significant relation between each 10-unit increase in NO 2 and CO, and premature birth in lag 0. Also, we found a significant association between each 10-unit increase in CO and premature delivery in lag 1; PM 10 and premature delivery in lags 10, 11, and 12; and NO and premature delivery in lags 3, 4, 10, 11, 12, and 13 (p value polluted air during pregnancy may increase adverse pregnancy outcomes and stillbirth. Pregnant women should avoid polluted air.

    Alcohol consumption during pregnancy is one potential risk factor for spontaneous abortion (SAb). Prior research suggested that heavy drinking during pregnancy was associated with significantly increased rates of SAb, but results for lower levels of drinking have been inconsistent. We examined the association between different levels and patterns of prenatal alcohol consumption and SAb in a high-risk inner-city sample. We hypothesized that higher levels, binge patterns, and more frequent drinking would be associated with increased rates of SAb. The quantity and frequency of self-reported peri-conceptional and repeated in-pregnancy maternal drinking volumes per beverage type were assessed with semi-structured interviews in a prospective subsample of 302 African-American mothers. Relations between various measures of prenatal alcohol exposure and SAb were assessed using logistic regression. After controlling for various potential confounders, there was a significant positive relation between average absolute alcohol use per day across pregnancy and SAb. Greater frequency of drinking episodes also predicted SAb: an average of even one day of drinking per week across pregnancy was associated with an increase in the incidence of SAb. However, contrary to our hypothesis, neither the amount of alcohol drunk per drinking day nor a measure of binge drinking was significantly related to SAb after controlling for confounders. Differences in when women who drank at risk levels initiated antenatal care may have under-estimated the impact of alcohol on SAb in this low-SES urban African-American sample. Some drinking measures averaged across pregnancy may have under-estimated consumption and overestimated risk of SAb, but other risk drinking measures that avoid this limitation show similar relations to SAb. Identifying fetal risk drinking in pregnant women is critical to increasing the effectiveness of interventions that reduce risk level alcohol consumption and protect from

    Full Text Available Abstract Background Research on the potentially adverse effects of occupational pesticide exposure on risk of spontaneous abortion (SAB is limited, particularly among female agricultural workers residing in developing countries. Methods Reproductive histories were obtained from 217 Ecuadorian mothers participating in a study focusing on occupational pesticide exposure and children's neurobehavioral development. Only women with 2+ pregnancies were included in this study (n = 153. Gravidity, parity and frequency of SAB were compared between women with and without a history of working in the cut-flower industry in the previous 6 years. Logistic regression analysis was conducted to assess the relation between SAB and employment in the flower industry adjusting for maternal age. Results In comparison to women not working in the flower industry, women working in the flower industry were significantly younger (27 versus 32 years and of lower gravidity (3.3 versus 4.5 and reported more pregnancy losses. A 2.6 (95% CI: 1.03-6.7 fold increase in the odds of pregnancy loss among exposed women was observed after adjusting for age. Odds of reporting an SAB increased with duration of flower employment, increasing to 3.4 (95% CI: 1.3, 8.8 among women working 4 to 6 years in the flower industry compared to women who did not work in the flower industry. Conclusion This exploratory analysis suggests a potential adverse association between employment in the cut-flower industry and SAB. Study limitations include the absence of a temporal relation between exposure and SAB, no quantification of specific pesticides, and residual confounding such as physical stressors (i.e., standing. Considering that approximately half of the Ecuadorian flower laborers are women, our results emphasize the need for an evaluating the reproductive health effects of employment in the flower industry on reproductive health in this population.

    Although it is well known that post-abortion contraceptive use is high when family planning services are provided following spontaneous or induced abortions, this relationship remains unclear in Brazil and similar settings with restrictive abortion laws. Our study aims to assess whether contraceptive use is associated with access to family planning services in the six-month period post-abortion, in a setting where laws towards abortion are highly restrictive. This prospective cohort study recruited 147 women hospitalized for emergency treatment following spontaneous or induced abortion in Brazil. These women were then followed up for six months (761 observations). Women responded to monthly telephone interviews about contraceptive use and the utilization of family planning services (measured by the utilization of medical consultation and receipt of contraceptive counseling). Generalized Estimating Equations were used to analyze the effect of family planning services and other covariates on contraceptive use over the six-month period post-abortion. Women who reported utilization of both medical consultation and contraceptive counseling in the same month had higher odds of reporting contraceptive use during the six-month period post-abortion, when compared with those who did not use these family planning services [adjusted aOR = 1.93, 95 % Confidence Interval: 1.13-3.30]. Accessing either service alone did not contribute to contraceptive use. Age (25-34 vs. 15-24 years) was also statistically associated with contraceptive use. Pregnancy planning status, desire to have more children and education did not contribute to contraceptive use. In restrictive abortion settings, family planning services offered in the six-month post-abortion period contribute to contraceptive use, if not restricted to simple counseling. Medical consultation, in the absence of contraceptive counseling, makes no difference. Immediate initiation of a contraceptive that suits women's pregnancy

    This article examines the struggle over abortion law reform that preceded the enactment in 1975 of the first statutory law on abortion in South Africa. The ruling National Party government produced legislation intended to eliminate access to doctors willing to procure abortions in an attempt to prevent young, unmarried white women from engaging in premarital (hetero) sexual activity. It was also aimed at strictly regulating the medical profession’s actions with regards to abortion. The production of the abortion legislation was directly influenced by international struggles for accessible abortion and, more broadly, sexual liberation. The regime believed South Africa was being infiltrated by Western "immorality" and the abortion law was an attempt to buttress racist heteropatriarchal apartheid culture. Examining the abortion controversy highlights the global circulation of ideas about reproduction in the twentieth century and foregrounds a neglected dimension of the history of sexual regulation in apartheid South Africa: the disciplining and regulation of white female reproductive sexuality.

    Cytoplasmic male sterility (CMS) is an important agricultural trait characterized by lack of functional pollen, and caused by ectopic and defective mitochondrial gene expression. The pollen function in CMS plants is restored by the presence of nuclear-encoded restorer of fertility (Rf) genes. Previously, we cloned Rf2, which restores the fertility of Lead Rice (LD)-type CMS rice. However, neither the function of Rf2 nor the identity of the mitochondrial gene causing CMS has been determined in LD-CMS rice. Here, we show that the mitochondrial gene orf79 acts as a CMS-associated gene in LD-CMS rice, similar to its role in BT-CMS rice originating from Chinsurah Boro II, and Rf2 weakly restores fertility in BT-CMS rice. We also show that RF2 promotes degradation of atp6-orf79 RNA in a different manner from that of RF1, which is the Rf gene product in BT-CMS rice. The amount of ORF79 protein in LD-CMS rice was one-twentieth of the amount in BT-CMS rice. The difference in ORF79 protein levels probably accounts for the mild and severe pollen defects in LD-CMS and BT-CMS rice, respectively. In the presence of Rf2, accumulation of ORF79 was reduced to almost zero and 25% in LD-CMS and BT-CMS rice, respectively, which probably accounts for the complete and weak fertility restoration abilities of Rf2 in LD-CMS and BT-CMS rice, respectively. These observations indicate that the amount of ORF79 influences the pollen fertility in two strains of rice in which CMS is induced by orf79. © 2016 The Authors The Plant Journal © 2016 John Wiley & Sons Ltd.

    Abortion is the termination of pregnancy prior to the 180th day, during which time the fetus is not yet viable outside the womb. Spontaneous abortion is the body's expulsion of a fetus during the 1st months of pregnancy. It is usually not very painful, does not involve much bleeding, and is rarely complicated by infection. Spontaneous abortion is much more frequent at the outset of pregnancy and may occur unnoticed. Its causes are unknown in over half of cases. The most important causes are developmental problems in the products of conception. Causes of spontaneous abortions of maternal etiology are most frequently uterine malposition or malformation. Serious illness in the mother is a less common cause of spontaneous abortion than once believed. Induced abortion is caused by the destruction of a normally implanted and healthy embryo. Its complications are related to the amount of bleeding or the introduction of germs from outside which can spread rapidly. Placental retention is a danger of all induced abortions. Induced abortion is common and in some countries it even creates demographic problems. Abortion is legal in many countries as an expression of the right to choose, but in others it is only legal on therapeutic grounds. Defenders and detractors of abortion have written extensively about it, with some works being sincere and some only tactical. The great majority of moralists are opposed to abortion, while biologists and scientists are divided on the question. The Spanish penal code punishes all persons who cause the death of a fetus or impede the process of gestation. The Catholic Church has considered abortion a homicide and against divine and natural laws. Legal or illegal, it is certain that the number of abortions increases each day. In the face of this reality, the need is for measures to avoid abortion whenever possible. Sex education in schools, full information on contraceptive methods and creation of family planning centers are some means of

    Insulin resistance (IR) was recognized as a risk factor for the occurrence of abortion in patients with polycystic ovary syndrome (PCOS). Chemerin was an adipokine which could induce IR and associated with reproductive process closely. However, few studies have inquired the relativity between chemerin and the occurrence of abortion in patients with PCOS. The aim of this study was to evaluate the relationship between serum chemerin and the occurrence of abortion in women with PCOS. We recruited 198 women with PCOS to participate in our study. On the third day of menstrual cycle or a random day in women with amenorrhea, we obtained their venous blood and measured the fasting insulin, fasting plasma glucose, total cholesterol, high density lipoprotein cholesterol, triglyceride, chemerin, and hormones including FSH, E2, P, PRL, LH, and T. Additionally, BMI, HOMA-IR and LH/FSH of each subject were calculated. Finally, 58 of them were included in the study, in which 30 of them had normal pregnancy and the other 28 had an early miscarriage. We compared the biochemical characteristics between the normal pregnancy group and abortion group by independent-samples t test. In our study, those with a normal pregnancy had a lower level of BMI, FINs, HOMA-IR, and chemerin compared to abortion patients (p PCOS patients (p PCOS. Thus, serum chemerin may serve as a biomarker to identify pregnant women with PCOS who are at particular risk for later abortion, and who may benefit from prevention strategies.

    Over-expression of the unedited mitochondrial orfB gene product generates male sterility in fertile indica rice lines in a dose-dependent manner. Cytoplasmic male sterility (CMS) and nuclear-controlled fertility restoration are widespread developmental features in plant reproductive systems. In self-pollinated crop plants, these processes often provide useful tools to exploit hybrid vigour. The wild abortive CMS has been employed in the majority of the "three-line" hybrid rice production since 1970s. In the present study, we provide experimental evidence for a positive functional relationship between the 1.1-kb unedited orfB gene transcript, and its translated product in the mitochondria with male sterility. The generation of the 1.1-kb unedited orfB gene transcripts increased during flowering, resulting in low ATP synthase activity in sterile plants. Following insertion of the unedited orfB gene into the genome of male-fertile plants, the plants became male sterile in a dose-dependent manner with concomitant reduction of ATPase activity of F1F0-ATP synthase (complex V). Fertility of the transgenic lines and normal activity of ATP synthase were restored by down-regulation of the unedited orfB gene expression through RNAi-mediated silencing. The genetic elements deciphered in this study could further be tested for their use in hybrid rice development.

    The relationship between viral infections and first-trimester spontaneous abortions is not well-understood. The study aim was to investigate the prevalence of cytomegalovirus (CMV), human parvovirus B19 (B19V), and herpes simplex virus-1/2 (HSV-1/2) infection by molecular and serological techniques in women experiencing spontaneous miscarriage in the first trimester of pregnancy. Plasma samples were examined for CMV, B19V, and HSV-1/2 DNA using real-time quantitative polymerase chain reaction (Real-time qPCR), and for specific IgG antibodies against B19V, CMV, and HSV-1/2 using serological assays. The abortion group consisted of women (n = 1,716) with a history of two or more first-trimester spontaneous abortions. Women younger than 30 years possess higher portion to experience spontaneous abortion. No specimens were positive for B19V or CMV DNA. Seven out of the 1,716 specimens were positive for HSV-1/2 DNA. By serology, 47.24% of patients were positive for B19V IgG, 39.66% for HSV IgG, 79.31% for CMV IgG, and 9.31% for B19V IgM. The high rate of positivity for CMV IgG suggests that the majority of women with first-trimester spontaneous abortions are not susceptible to primary CMV infection. The lack of virus DNA in the majority of cases indicates that B19V, CMV, and HSV-1/2 infection is not commonly associated with first-trimester spontaneous abortion. © 2015 Wiley Periodicals, Inc.

    The researchers conducted a cross-sectional survey to determine the relationship between handling heavy items during pregnancy and spontaneous abortion among working women in South Korea. One thousand working women were selected from a database of those eligible for maternity benefits under the National Employment Insurance Plan. Study results showed that handling heavy items during pregnancy was associated with an increased risk of spontaneous abortion after adjusting for general characteristics of the participants and their work environment. A collective effort is needed on the parts of employers, employees, occupational health nurses, and the government to protect working women from lifting heavy items while pregnant.

    Humans are widely exposed to phthalates, bisphenol A and nonylphenol owing to the ubiquitous use of these chemicals in consumer products. Increasing attention has been paid to exposure to phthalates, bisphenol A and nonylphenol because of their potential adverse effects on human fertility. A validated method was developed to investigate the three classes of environmental estrogen, mentioned above, in the urine of Chinese women of Nanjing area with unexplained recurrent spontaneous abortion. Solid-phase extraction coupled with ultra performance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS) was used. In this method, amounts of bisphenol A (BPA), nonylphenol (NP) and four phthalate metabolites, mono-n-butyl phthalate (MBP), mono-isobutyl phthalate (MiBP), mono-benzyl phthalate (MBzP) and mono-2-ethylhexyl phthalate (MEHP), along with their isotope labeled internal standards, were measured using UPLC-MS/MS operated in negative electrospray ionization multiple reaction monitoring mode. The limits of detection were 0.3 ng/mL for the four phthalate metabolites, and 0.5 ng/mL for bisphenol A and nonylphenol. For women with unexplained recurrent spontaneous abortion, the mean concentrations of MBP, MiBP, MBzP, MEHP, BPA and 4-n-NP were 6.52±6.04, 5.51±4.19, 0.53±0.42, 10.12±4.16, 7.13±7.42, 0.41±0.49 ng/mL (mean±SD), respectively. For the control group, the mean concentrations of the corresponding analytes were 4.15±3.57, 2.96±3.30, 0.46±0.49, 6.50±2.81, 4.43±2.23,0.48±0.43 ng/mL (mean±SD), respectively. Levels of MiBP and MEHP were significantly different between the two groups, using Wilcoxon rank sum tests. This method can be applied in epidemiological studies to explore the association between exposure to environmental estrogens and relevant adverse outcomes. - Highlights: • Studied on the exposure level of six analytes in Chinese women with unexplained recurrent spontaneous abortion. • Differences in MEHP and MiBP urine levels were

    Results: Out of 51 subjects, 18 had positive Anti-TPO-Ab, of which -10 were among the cases and 8 belonged to the controls. Out of 18 women with positive AntiTG-Ab, 11 cases were in the control group and 7 were in the cases. The differences between the control group and the amounts of Anti-TPO-Abs (P=0.468 and Anti-TG-Abs (P=0.675 were not swignificant. Conclusion: The results revealed that there is no association between abortion and presence of antithyroid antibodies in mother’s serum. Other abortion causes such as various kinds of infections and smoking might be involved which requires more research.

    Introduction Adenosine and deoxyadenosine metabolism is influenced by adenosine deaminase (ADA) enzyme. ADA increases in different diseases and is considered as one of the markers for cell-mediated immunity. Pregnancy is associated with depressed cell-mediated immunity. The level of ADA expression, which seems to play a key role in maintaining pregnancy, is influenced by adenosine deaminase G22A gene polymorphism. We aimed in our study to evaluate the association of ADA G22A gene polymorphism with recurrent spontaneous abortion (RSA) in Egyptian women. Material and methods Adenosine deaminase G22A gene polymorphism was genotyped in 40 patients (age range 22-39 years) with a history of RSA, selected from those attending the Gynaecology and Obstetrics Clinic of Beni-Suef University Hospital, and 20 age-matched healthy women as a control group, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Results In our study, no statistically significant difference was found between RSA patients and control group as regards ADA G22A genotypes (p = 0.653) and alleles (p = 0.697). A comparison of the frequencies of ADA alleles in RSA patients as regards the below-35-years-old age group revealed that ADA 2(A) allele was associated with a low risk for RSA in patients aged 35 years old or younger (p = 0.008). Conclusions In conclusion, our study revealed an age-dependent protective value of ADA 2(A) allele in recurrent spontaneous abortions among the Egyptian population. PMID:29204093

    The aim of this study was to explore the association of the DNA-methyltransferase (DNMT)-3A and DNMT3B promoter polymorphisms with the risk of human spontaneous abortion after assisted reproduction techniques (ARTs) and natural conception. We collected tissues from women who underwent abortion procedures: (a) chorionic villus samples (CVS) and muscle samples (MS) from spontaneous abortions conceived by ART and natural cycle (study group), n = 152; and (b) CVS and MS from normal early pregnancy and second trimester (control group), n = 155. The single-nucleotide polymorphism (SNP) -448A > G in the DNMT3A promoter region and -149C/T polymorphism of DNMT3B were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and confirmed by sequencing. The allele frequency of -448A among pregnancy loss group and control group was 34.2 % vs. 16.5 %, respectively. Compared with GG carriers, the DNMT3A -448AA homozygotes had an about 16-fold increased risk of spontaneous abortion [odds ratio (OR) = 16.130, 95 % confidence interval (CI), 3.665-70.984], and AG heterozygotes had an OR of 2.027 (95 % CI, 1.247-3.293). However, the distribution of -448A > G in individuals derived from ART pregnancies was not statistically significantly compared with those derived from spontaneous pregnancies (P = 0.661). For DNMT3B, we observed genotype frequencies of 100 % (TT) in the study group and the control group. The DNMT3A -448A > G polymorphism may be a novel functional SNP and contribute to its genetic susceptibility to spontaneous abortion in Chinese women, and ART may not affect the distribution of -448A > G in pregnancy loss and normal pregnancy. The observed TT genotype of DMNT3B suggests that this is the predominant genotype of this population. The findings provide new insights into the etiology of human spontaneous abortion.

    Full Text Available Variability of male fertility expression in the AS-1 line, a somaclonal variant obtained from tissue culture of CMS-plant, and in the progeny of revenant '124-1' obtained from fertile tiller, which developed on CMS-plant transferred from the field to the greenhouse, was investigated. Both revertants were characterized by similar expression of male fertility during plant ontogenesis: the panicle on the main tiller was almost completely sterile whereas formation of fertile pollen grains and seed set were observed on the panicles of the shoot tillers. A clear basipetal gradient of male fertility was manifested on all panicles: the base had significantly higher per cent of fertile pollen grains in comparison with the middle part, while in the top the anthers were either absent or had few sterile pollen grains. Such an ontogenetically-regulated restoration of male fertility was controlled by nuclear genes and could be transferred through the pollen in crosses with progenitor CMS-line. Growing of AS-1 plants in the growth chambers simultaneously under a long (16/8 and a short (12/12 daylength conditions demonstrated that differences of fertility level in different tillers was not caused by change of photoperiod during plant ontogenesis and functioning of photoperiod-sensitive fertility restoring gene. Whereas, the ontogenetically-regulated expression of male fertility in both revenants was temperature-dependent and was clearly manifested under relatively cool conditions during 2-week period before the beginning of anthesis of the first panicle (average daily temperature 21°C. The increase of the average daily temperature by 2-3 С resulted in sharp increase of male fertility level. Possibility of using AS-1 line in a new "two-line system" of hybrid seed production, which require only two lines (sterile mutant and fertility restorer, is discussed.

    Fertility is high in Nigeria and contraceptive use is low. Little is known about how urban Nigerians perceive the risk of contraceptive use in relation to pregnancy and birth. This study examines and compares the risk perception of family planning methods and pregnancy related scenarios among urban Nigerians. A total of 26 focus group discussions with 243 participants were conducted in September and October 2010 in Ibadan and Kaduna. The groups were stratified by sex, age, family planning use, and city. Study participants were asked to identify the risk associated with six different family planning methods and four pregnancy related risks. The data were coded in ATLAS.ti 6 and analyzed using the thematic content analysis approach. The ten family planning and pregnancy related items ranked as follows from most to least risky: sterilization, abortion, getting pregnant soon after having a baby (no birth spacing), pill, IUD, injectable, having a birth under 18 years of age (teenage motherhood), condom use, having six children, and fertility awareness methods. Risk of family planning methods was often categorized in terms of side effects and complications. Positive perceptions of teenage motherhood and having many children influenced the low ranking of these items. Inadequate birth spacing was rated as more risky than all contraceptive methods and pregnancy related events except for sterilization and abortion. Some of the participants' risk perceptions of contraceptives and pregnancy related scenarios does not correspond to actual risk of methods and practices. Instead, the items' perceived riskiness largely correspond with prevailing social norms. However, there was a high level of understanding of the risks of inadequate birth spacing. This study is not a randomized control trial so the study has not been registered as such.

    It has been proposed that transcobalamin 2 (TCN2) and the transcobalamin 2 receptor (TCN2R) are associated with idiopathic recurrent spontaneous abortion (RSA). The aim of the present study was to investigate the impact of TCN2 rs1801198 and TCN2R rs2336573 polymorphism on RSA in a sample of Iranian population. This case-control study was done on 92 RSA patients and 93 normal, fertile women. Genotyping of the TCN2 rs1801198 and TCN2R rs2336573 variants was done by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). The findings showed no significant association between the TCN2 rs1801198 and TCN2R rs2336573 polymorphisms and the risk/protection of RSA. Our results did not support an association between the TCN2 polymorphism and the risk of RSA in a sample of southeast Iranian population. Larger studies with different ethnicities are needed to evaluate the possible impact of TCN2 and TCN2R polymorphisms on the pathogenesis of RSA. Impact statement What is already known on this subject? Recurrent spontaneous abortion (RSA), a multifactorial condition, is one of the most common complications of pregnancy. It has been proposed that genetic polymorphisms play a role in the pathogenesis of RSA. Few studies have examined the association between TNC2 and TCN2R polymorphisms and the RSA risk and the findings were inconsistent. The aim of the current study was to determine the possible association between the TCN2 rs1801198 and TCN2R rs2336573 polymorphisms and the RSA in a sample of the southeast Iranian population. What do the results of the study add? The findings of the present case-control study did not support an association between the TCN2 rs1801198 and TCN2R rs2336573 polymorphisms and the risk of RSA in a sample of the Iranian population. What are the implications of these findings for clinical practice and future research? The findings of this study may provide a basis for future studies with larger sample sizes and different ethnicities

    CMS, which refers to the inability to generate functional pollen grains while still producing a normal gynoecium, has been widely used for pepper hybrid seed production. Pepper line 8214A is an excellent CMS line exhibiting 100% male sterility and superior economic characteristics. A TUNEL assay revealed the nuclear DNA is damaged in 8214A PMCs during meiosis. TEM images indicated that the 8214A PMCs exhibited asynchronous meiosis after prophase I, and some PMCs degraded prematurely with morphological features typical of PCD. Additionally, at the end of meiosis, the 8214A PMCs formed abnormal non-tetrahedral tetrads that degraded in situ. To identify the genes involved in the pollen abortion of line 8214A, the transcriptional profiles of the 8214A and the 8214B anthers (i.e., from the fertile maintainer line) during meiosis were analyzed using an RNA-seq approach. A total of 1355 genes were determined to be differentially expressed, including 424 and 931 up- and down- regulated genes, respectively, in the 8214A anthers during meiosis relative to the expression levels in the 8214B. The expression levels of ubiquitin ligase and cell cycle-related genes were apparently down-regulated, while the expression of methyltransferase genes was up-regulated in the 8214A anthers during meiosis, which likely contributed to the PCD of these PMCs during meiosis. Thus, our results may be useful for revealing the molecular mechanism regulating the pollen abortion of CMS pepper. Copyright © 2017. Published by Elsevier B.V.

    From early pregnancy, maternal hemodynamic profile begins to change. The absence of these changes leads to increased risk of complication during the gestation. Aim of this study is to understand in early pregnancy the behaviour of total vascular resistances (TVR) as a sign of maternal cardiovascular adaptation to pregnancy. A cross section study was conducted. We followed 160 healthy women with singleton pregnancy during the first trimester of gestation. We evaluated cardiac output (CO) and TVR at 7, 9 and 11 weeks of gestation. We obtained the following haemodynamic measurements with the USCOM system, a non invasive method: heart rate (HR), systolic and diastolic blood pressure (SBP, DBP), CO and TVR. 160 healthy pregnant women were selected, 8 patients, were excluded for a bad signal. Absolute values of the haemodynamic measures are shown in Fig. 1. 41 patients underwent spontaneous embryonic demise. This last group of patients showed in 54% (group A) TVR values within the normal limits (TVR1200) and CO values below the normal adaptation to pregnancy. Table 1 shows hemodynamic measures for the group A and group B; we found differences in term of CO, TVR and PAS between the two groups. Elevated TVR might indicate an abnormal vascular adaptation already in first weeks of pregnancy. Moreover, in women who undergo to abortion, elevated TVR could be use to distinguish genetic or environmental causes of miscarriage. Copyright © 2013. Published by Elsevier B.V.

    To investigate the association between the polymorphisms of signal transducer and activator of transcription 4 (STAT4) gene and the susceptibility to unexplained recurrent spontaneous abortion(URSA). PCR-restriction fragment length polymorphism (PCR-RFLP) was used to detect genotype 3 loca (rs7574865 G/T, rs10181656 C/G and rs16833431 C/T) polymorphism of STAT4 in 246 URSA cases (URSA group) and 183 normal controls (control group) . (1)The frequencies of rs7574865 were genotype G/G of 36.2% (89/246) in URSA group and 46.4% (85/183) in control group, genotype G/T of 47.2% (116/246) in URSA group and 45.4% (83/183) in control group, and genotype T/T of 16.7% (41/246) in URSA group and 8.2% (15/183) in control group, which reached statistical difference (P rs7574865 T allele and rs10181656 G allele increased the risk of URSA (OR = 1.51, 1.44, all P rs7574865 G/T and rs10181656 C/G showed haplotype G-T conferring the susceptibility to URSA (OR = 1.49, P < 0.01), but haplotype C-G could provide protection on URSA (OR = 0.68, P < 0.01). Polymorphisms of STAT4 gene might confer the susceptibility to URSA by altering STAT4 function and (or) its expression.

    Recurrent spontaneous abortion (RSA) is defined as three or more consecutive spontaneous abortions before the 20th week of gestation. The purpose of the present study was to investigate the association between a functional single nucleotide polymorphism (SNP) in the interleukin (IL)-23 receptor gene (IL-23R; rs11209026, 1142 G wild type → A reduced function, Arg381Gln, R381Q) and RSA. For the study, 200 RSA patients (confirmed using established diagnostic criteria) and 200 normal individuals in fertility and infertility centers in the cities of Yazd and Isfahan were recruited during a period from 2012-2013. Using PCR-RFLP, the R381Q variant was screened for in the IL-23R gene of the patients and controls. The results indicated there were significant differences in the frequency of this genetic variant in the patients versus the healthy controls, i.e. 2% and 7.5%, respectively (p value = 0.01; odds ratio = 0.25; CI = 95%). No significant difference was found for the G allelic frequency in patients with RSA and in the control group (p = 0.60). The A allelic frequency was significantly different between the two groups (p = 0.01). Based on these findings, it is concluded that the frequency of single nucleotide polymorphism in the IL-23 receptor (R381Q) in patients with recurrent spontaneous abortion (RSA) is less than that found in normal control women.

    Full Text Available Background: Disorders in immune system regulation may result in pregnancy abnormalities such as recurrent spontaneous abortion (RSA. This study aims to determine the ratio of regulatory T (Treg and T helper (Th 17 cells in unexplained RSA (URSA women during proliferative and secretory phases of their menstrual cycles compared to healthy non-pregnant women. Materials and Methods: In this case control study, 25 women with URSA and 35 healthy, non-pregnant women were enrolled. The percentage of Th17 and Treg cells in participants peripheral blood were determined by flow cytometry. Results: The percentage of Th17 cells and their related cytokines in serum (IL-17A were higher in the proliferative and secretory phases of the menstrual cycles of URSA women compared to the control women. However, a lower percentage of Treg cells and their related cytokines in serum, transforming growth factor (TGF β1 and interleukin (IL-10 were detected in the proliferative but not the secretory phase of the URSA group. The ratio of Th17/CD4+ Treg was higher in the URSA group than the control group. We observed an increased ratio of Th17/CD4+ Treg during the proliferative and secretory phases in URSA women. Conclusion: The imbalance between Th17 and Treg cells during the proliferative phase of menstrual cycles in the URSA group may be considered a cause for spontaneous abortion.

    To comprehensively evaluate the association of paternal smoking and spontaneous abortion. We conducted a population-based retrospective cohort study among 5 770 691 non-smoking rural Chinese women, along with their husbands, participating in the National Free Pre-Pregnancy Checkups Project, regarding outcome events that occurred in 2010-2016. The main outcome was spontaneous abortion (SA). Multivariable logistic regression was used to estimate OR and 95% CI, and restricted cubic spline was used to estimate the non-linear relationship. The multivariable-adjusted OR of exposure to paternal smoking for SA was 1.17 (95% CI 1.16 to 1.19), compared with women without exposure to paternal smoking; and corresponding OR of exposure to preconception paternal smoking for SA was 1.11 (95% CI 1.08 to 1.14), compared with women without exposure to preconception paternal smoking. The ORs of preconception paternal smoking also increased with increases in paternal smoking (p nonlinear 0.05). In addition, periconception paternal smoking cessation was associated with an 18% (15%-22%) lower risk of SA. Paternal smoking was associated with SA. The importance of tobacco control, specifically pertaining to paternal smoking, should be emphasised during preconception and pregnancy counselling. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Recurrent spontaneous abortion (RSA) is a common health problem affecting women of reproductive age. Altered expression of vascular endothelial growth factor ( VEGF ) has been associated with spontaneous abortion. The present case-control study aimed to evaluate the impact of the 18-bp insertion/deletion (ins/del) polymorphism (rs35569394) in the promoter region of the VEGF gene on idiopathic RSA. Genomic DNA from 93 patients with RSA and 93 healthy fertile women of southeastern Iran was isolated using the salting-out method. Genotyping of the rs35569394 variant was performed by a polymerase chain reaction (PCR) method. The findings indicated that the VEGF 18-bp ins/del variant significantly increased the risk of RSA under codominant (ins/ins vs. del/del; OR=2.85, 95% CI=1.31-6.22, P=0.019), dominant (del/ins+ins/ins vs. del/del; OR=2.19, 95% CI=1.20-4.01, P=0.015) and allelic (ins vs. del; OR=1.90, 95% CI=1.25-2.88, P=0.003) inheritance models. In summary, the findings propose a significant association between the VEGF 18-bp ins/del polymorphism and risk of RSA in a sample of the southeast Iranian population. Further studies on larger sample sizes and different ethnicities are required to validate the present findings.

    The objective was to investigate the subsets of natural killer T (NKT)-like cells and the expression of Th1/Th2 cytokines in the peripheral blood (PB) and/or decidual tissue of patients with unexplained recurrent spontaneous abortion (URSA). The percentages of NKT-like cells in the PB and deciduas of URSA patients in early pregnancy and in the PB of nonpregnant women were analyzed by flow cytometry. The expression of interferon (IFN)-γ (Th1 cytokine) and Th2 cytokines, interleukin (IL)-4 and IL-10, in the PB and decidual tissue was measured by quantitative RT-PCR and enzyme-linked immunosorbent assay (ELISA). Most percentages of subsets of NKT-like cells (CD3(+)CD56(+), CD3(+)CD56(+)CD16(+)) in the PB and deciduas were significantly greater in URSA patients than in normal pregnant and nonpregnant women. A cut-off value of 3.75% for the increased percentage of CD3(+)CD56(+)CD16(+) NKT-like cells in the PB appeared to be predictive of pregnancy failure. Moreover, we found that in the decidua, IFN-γ expression was significantly higher, while IL-4 and IL-10 expression was significantly lower in URSA patients compared with those with a normal pregnancy. The ratio of decidual Th1/Th2 cytokines in URSA patients was significantly increased compared with that in normal pregnant women. Decidual IL-4 expression correlated negatively with the percentages of blood CD3(+)CD56(+)CD16(+) NKT-like cells and the decidual CD3(+)CD56(+) and CD3(+)CD56(+)CD16(+) NKT-like cells. NKT-like cells may play an important role in maintaining normal pregnancy. Measurement of CD3(+)CD56(+)CD16(+) NKT-like cells in the PB may provide a potential tool for assessing patients' risk of spontaneous abortion. Copyright © 2015. Published by Elsevier Ireland Ltd.

The results demonstrated that SSRIs increase the risk of spontaneousabortion and major malformations during pregnancy while they don’t increase the risk of cardiovascular malformations and minor malformations. Our previous meta-analysis only showed an increase in the risk of spontaneous abortion following the use of SSRIs duringpregnancy. This might be due to increase in the number of studies included or addition of two new SSRIs (citalopram and escitalopram. The message to researchers is to try considering SSRIs individually during pregnancy to reduce heterogeneity, although all are aware ofinevitable limitations to study on pregnant mothers.

    Three completely-sterile cowpea mutants IT85D-3625, IT85D-3628, IT85D-3641 obtained from spontaneous mutation and gamma irradiation were-characterized. Reciprocal crosses between them and fertile plants failed to set pods. These lines showed significant differences with respect to various traits such as number of pollen grain per anther, anther length and width, plant height, anther indehiscence,unopened flower buds, and premature abortion of pods and seeds. The major cause of sterility was chromosome aberrations. Complete sterility in each of the three lines was conditioned by a simple recessive gene pair. Sterility in each of the three mutants was associated with floral aberrations. The symbols cs 1 , cs 2 and cs 3 are being assigned to IT85D-3625, IT85D-2628 and IT85D-3641 respectively. The three mutants were homogeneous with reference to sterility inheritance. (au)

    Meerkats are group-living, insectivorous herpestids in which subordinate members provide extensive care for the dominant female's young. In contrast to some cooperative breeders, subordinate female meerkats are physiologically able to reproduce and occasionally do so successfully; their attempts are more frequently 'suppressed' via eviction or infanticide by the dominant female. Spontaneous abortion and neonatal loss occur with some regularity, further negatively impacting reproductive success. Here, we compared the reproductive outcomes and endocrine profiles, including of serum progesterone (P 4 ), serum estradiol (E 2 ), and fecal glucocorticoid metabolites (fGCm), of dominant and subordinate dams residing within their clans in the Kalahari Desert of South Africa. Our study spanned years of drought, which reduced insect abundance and represented a substantial environmental stressor. Meerkat pregnancies were identified at mid-term and culminated either in spontaneous abortions or full-term deliveries, after which pups were either lost prior to emergence from the natal den (usually within 2days of birth) or emerged at 2-3weeks. Neonatal loss exceeded fetal loss for all females, and contributed to narrowing the status-related disparity in female reproductive output seen during less arid periods. Although E 2 concentrations were significantly lower in subordinate than dominant females, they were sufficient to support gestation. Absolute E 2 concentrations may owe to androgenic precursors that also attain highest concentrations in dominant dams and may mediate aggression underlying female reproductive skew. Pregnancies terminating in fetal loss were marked by significantly lower P 4 concentrations in mid-gestation and modestly lower E 2 concentrations overall. Consistently high fGCm concentrations further increased across trimesters, particularly (but not consistently) in subordinates and in aborted pregnancies. Environmental stressors may modulate reproductive

  16. Legalized abortion in Japan.

    The enactment of the Eugenic Protection Act in Japan was followed by many changes. The population explosion was stemmed, the birth rate was halved, and while the marriage rate remained steady the divorce rate declined. The annual total of abortions increased until 1955 and then slowly declined. The highest incidence of abortions in families is in the 30 to 34 age group when there are four children in the family. As elsewhere abortion in advanced stages of pregnancy is associated with high morbidity and mortality. There is little consensus as to the number of criminal abortions. Reasons for criminal abortions can be found in the legal restrictions concerning abortion: Licensing of the abortionist, certification of hospitals, taxation of operations and the requirement that abortion be reported. Other factors are price competition and the patient's desire for secrecy. Contraception is relatively ineffective as a birth control method in Japan. Oral contraceptives are not yet government approved. In 1958 alone 1.1 per cent of married women were sterilized and the incidence of sterilization was increasing.

    Prior to 1976, voluntary female sterilization was 1 of the regular family planning services offered in Chile. After that the Ministry of Public Health declared that it could not be considered a fertility regulation activity and could thus be performed only for health reasons. Between 1971-75, there was almost a 6-fold increase in the number of sterilizations performed at the Valdivia Regional Hospital, with a rise to 2400 procedures. Such an unprecedented increase in voluntary sterilization prompted this study. The results are based on a 1976 survey of women sterilized between 1971-75 at the Valdivia Regional Hospital. Personal interviews were conducted. The number of voluntary sterilizations there during the aforementioned period showed a sustained upward trend; the number of births increased only moderately during that time. The data on sterilization in the Valdivia area is compared to that collected by the Santiago study. Age, marital status, place of origin or residence, education, and religion were compared. Socioeconomic and occupational data were also examined. 9 of 10 women in Valdivia were from low-income families. This agrees closely with the Santiago data. About 1/4 of the women in both samples were employed outside the home. Also in both samples, about 1/2 of the spouses of sterilized women were blue collar workers; only 1/5 or less were white collar, and very few were professionals. About 52% in Valdivia and 45% in Santiago had borne 7 or more viable offspring. The average number of spontaneous abortions was also similar. A significantly higher percentage (P0.01) of Valdivia women used contraceptives. There are some general trends apparent in both groups as to the reasons for sterilization; most were prompted by difficult socioeconomic conditions. 37.9% of the Santiago women felt their families were complete and 27.3% of the other group cited the same reason. Other reasons were medical, failure of contraception, problems with spouse, and other. Medical

  20. Active suppression of host-vs-graft reaction in pregnant mice. VII. Spontaneous abortion of allogeneic CBA/J x DBA/2 fetuses in the uterus of CBA/J mice correlates with deficient non-T suppressor cell activity

    The mammalian fetus has been viewed as an unusually successful type of allograft and unexplained spontaneous abortion as a possible example of maternal rejection. Previous studies have shown the presence of small lymphocytic suppressor cells in the murine decidua which block the generation and reactivation of anti-paternal cytotoxic T lymphocytes (CTL) and lymphokine-activated killer cells (LAK) by elaborating a factor that inhibits the response to interleukin 2 (IL 2). A deficiency of these suppressor cells was associated with implants of xenogeneic Mus caroli embryos in the Mus musculus uterus which are infiltrated by maternal lymphoid cells and aborted. A deficiency of such suppressor cells in the lymph nodes draining the uterus of CBA/J females in the process of aborting their semi-allogeneic CBA x DBA/2 F 1 progeny has also been shown. CBA/J females possess significantly lower levels of decidua-associated non-T suppressor cells on day 8.5 to 10.5 of allopregnancy than do mothers that will produce large litters of live babies. The F 1 embryos are infiltrated by maternal lymphocytes prior to abortion, and the infiltration and abortion rate appears to be augmented by pre-immunization with paternal DBA/2 spleen cells. The CBA/J x DBA/2J mating combination provides a model of spontaneous abortion in which immunologic factors play an important role and demonstrates that the association between deficiency of decidua-associated suppressor cells and xenopregnancy failure also holds true for the failure of allopregnancies resulting from natural within-species mating

    Systemic monitoring of immune system may not precisely outline the local immune status in the uterus. This survey is a continuation of our previous studies on potential usefulness of menstrual blood (MB) immunophenotyping as a tool for investigation of immunological disturbances in pregnancy-related disorders. Peripheral blood (PB) and MB from healthy fertile (n = 15), unexplained recurrent spontaneous abortion (URSA; n = 15), and unexplained infertile women (n = 8) were collected simultaneously in the second day of their menstrual cycle and frequency of natural killer T (NKT)-like cell subpopulations were assessed by flow cytometry. Menstrual blood of all experimental groups contained higher percentage of TCRαβ + , CD45RO + , and CD16 - NKT-like cells compared to corresponding PB. Frequency of MB NKT-like cells in unexplained infertile participants was lower than fertile and URSA groups. Compared to normal participants, patients with URSA had lower frequency of PB TCRαβ + and higher CD16 + , while in infertile woman frequencies of PB CD45RO + , CD45RO - , CD16 - , IL17 + , and MB CD45RO + NKT-like cells were lower. Although, PB and MB seemingly have the same histological nature, our results showed that MB contained different composition of NKT-like subsets with different cytokine profiles and could be viewed as one potential biological sample for evaluation of patients with infertility and URSA.

    The aim of the present study was to investigate the role of CAG repeat polymorphism and X-chromosome Inactivation (XCI) pattern in Recurrent Spontaneous Abortions among Indian women which has not been hitherto explored. 117 RSA cases and 224 Controls were included in the study. Cases were recruited from two different hospitals - Lakshmi Fertility Clinic, Nellore and Fernandez Maternity Hospital, Hyderabad. Controls were roughly matched for age, ethnicity and socioeconomic status. The CAG repeats of the Androgen Receptor gene were genotyped using a PCR-based assay and were analysed using the GeneMapper software to determine the CAG repeat length. XCI analysis was also carried out to assess the inactivation percentages. RSA cases had a significantly greater frequency of allele sizes in the polymorphic range above 19 repeats (p = 0.006), which is the median value of the controls, and in the biallelic mean range above 21 repeats (p = 0.002). We found no evidence of abnormal incidence of skewed X-inactivation. We conclude that longer CAG repeat lengths are associated with increased odds for RSA with statistical power estimated to be ∼90%.

    The establishment and maintenance of successful pregnancy mainly depends on trophoblast cells. Their dysfunction has been implicated in recurrent spontaneous abortion (RSA), a major complication of pregnancy. However, the underlying mechanisms of trophoblasts dysfunction remain unclear. DNA-damage-induced cell apoptosis has been reported to play a vital role in cell death. In this study, we identified a novel microRNA (miR-520) in RSA progression via regulating trophoblast cell apoptosis. Microarray analysis showed that miR-520 was highly expressed in villus of RSA patients. By using flow cytometry analysis, we observed miR-520 expression was correlated with human trophoblast cell apoptosis in vitro, along with decreased poly (ADP-ribose) polymerase-1 (PARP1) expression. With the analysis of clinic samples, we observed that miR-520 level was negatively correlated with PARP1 level in RSA villus. In addition, overexpression of PARP1 restored the miR-520-induced trophoblast cell apoptosis in vitro. The status of chromosome in trophoblast implied that miR-520-promoted DNA-damage-induced cell apoptosis to regulate RSA progression. These results indicated that the level of miR-520 might associate with RSA by prompting trophoblast cell apoptosis via PARP1 dependent DNA-damage pathway.

    The relationship between T cell immunoglobulin domain and mucin domain protein 3 (Tim-3)/Galectin (Gal)-9 pathway and recurrent spontaneous abortion (RSA) was studied. Thirty-one pregnant women with RSA and 27 normal early gravidas were investigated to detect the levels of Tim-3 and Gal-9 in villi and deciduas by Western blotting. Meanwhile, the concentration of interleukin (IL)-4 and IL-12 in peripheral blood plasma was determined by ELISA in 25 healthy fertile non-pregnant controls, the normal early gravidas and pregnant women with RSA mentioned above, respectively. It was found that the relative expression levels of Tim-3 and Gal-9 in villi and deciduas were significantly increased in pregnant women with RSA as compared with those in the normal early gravidas. The concentration of IL-4 in peripheral blood plasma of pregnant women with RSA was lower than that of the normal early gravidas (Ppregnant controls (Ppregnant women with RSA was significantly higher than that of the normal early gravidas (Ppregnant controls (P<0.05). It was suggested that the overexpression of Tim-3/Gal-9 pathway may be related to the pathogenesis of RSA.

    Objectives Despite the global expansion of supply chains and changes to the production process, few studies since the mid-1990s and 2000s have examined reproductive risks of the microelectronics industry; we examined the reproductive risks among female microelectronics workers in South Korea. Methods Based on claim data from the National Health Insurance (2008–2012), we estimated age-specific rates of spontaneous abortion (SAB) and menstrual aberration (MA) among women aged 20 to 39 years. We compared data between microelectronics workers and three different control groups: economically inactive women, the working population as a whole, and workers employed in the bank industry. For an effect measure, age-stratified relative risks (RRs) were estimated. Results Female workers in the microelectronics industry showed significantly higher risk for SAB and MA compared to control groups. The RRs for SAB with reference to economically inactive women, working population, and bank workers in their twenties were 1.57, 1.40, and 1.37, respectively, and the RRs for MA among females in their twenties were 1.54, 1.38, and 1.48, respectively. For women in their thirties, RRs for SAB were 1.58, 1.67, and 1.13, and those for MA were 1.25, 1.35, and 1.23 compared to the three control populations, respectively. All RRs were statistically significant at a level of 0.05, except for the SAB case comparison with bank workers in their thirties. Conclusions Despite technical innovations and health and safety measures, female workers in microelectronics industry in South Korea have high rates of SAB and MA, suggesting continued exposure to reproductive hazards. Further etiologic studies based on primary data collection and careful surveillance are required to confirm these results. PMID:25938673

    Threatened abortion is the most common complication in the first half of pregnancy. Most of these pregnancies continue to term with or without treatment. Spontaneous abortion occurs in less than 30% of these women. Threatened abortion had been shown to be associated with increased incidence of antepartum haemorrhage, preterm labour and intra uterine growth retardation. This study was to asses the outcome of threatened abortion following treatment. This prospective study was carried out in Dhulikhel Hospital - Kathmandu University Hospital from January 2009 till May 2010. Total 70 cases of threatened abortion were selected, managed with complete bed rest till 48 hrs of cessation of bleeding, folic acid supplementation, uterine sedative, and hormonal treatment till 28 weeks of gestation. Ultrasonogram was performed for diagnosis and to detect the presence of subchorionic hematoma. Patients were followed up until spontaneous abortion or up to delivery of the fetus. The measures used for the analysis were maternal age, parity, gestational age at the time of presentation, previous abortions, presence of subchorionic hematoma, complete abortion, continuation of pregnancy, antepartum hemorrhage, intrauterine growth retardation and intrauterine death of fetus. Out of 70 cases subchorionic haematoma was found in 30 (42.9%) cases. There were 12 (17.1%) patients who spontaneously aborted after diagnosis of threatened abortion during hospital stay, 5 (7.1%) aborted on subsequent visits while 53 (75.8%) continued pregnancy till term. Among those who continued pregnancy intrauterine growth retardation was seen in 7 (13.2%), antepartum hemorrhage in 4 (7.5%), preterm premature rupture of membrane in 3 (5.66%) and IUD in 3 (5.66%). Spontaneous abortion was found more in cases with subchorionic hematoma of size more than 20 cm2. In cases of threatened abortion with or without the presence of subchorionic hematoma, prognostic outcome is better following treatment with bed rest

  15. Sterilization in Finland: from eugenics to contraception.

    The purpose of this paper was to describe the transition of sterilization in Finland from an eugenic tool to a contraceptive. Historical data were drawn from earlier reports in Finnish. Numbers of and reasons for sterilizations since 1950 were collected from nationwide sterilization statistics. Prevalence, characteristics of sterilized women, and women's satisfaction with sterilizations were studied from a 1994 nationwide survey (74% response rate). Logistic regression was used for adjustments. In the first half of the 20th century, eugenic ideology had influence in Finland as in other parts of Europe, and the 1935 and 1950 sterilization laws had an eugenic spirit. Regardless of this, the numbers of eugenic sterilizations remained low, and in practice, family planning was the main reason for sterilization. Nonetheless, prior to 1970 not all sterilizations were freely chosen, because sterilizations were sometimes used as a precondition for abortion. Female sterilizations showed remarkable fluctuation over time. Male sterilizations have been rare. The reasons stipulated by the law did not explain the numbers of sterilizations. In a 1994 survey, 9% of Finnish women reported they were using sterilization as their current contraceptive method (n = 189). Compared to women using other contraceptive methods, sterilized women were older, had had more births and pregnancies, and came from lower social classes. Sterilized women were satisfied with their sterilization, but there were women (8.5%) who regretted it. In conclusion, sterilizations have been and are likely to continue to be an important family planning method in Finland. The extreme gender ratio suggests a need for promoting male sterilizations, and women's expressed regrets suggest consideration of a higher age limit.

    . The narrative analysis was the research method. The narratives of seventeen men were analysed. The spontaneous abortion related feelings were the loss related anguish and, the provoked abortion, the culpability related feelings and its consequences. Men who share the abortion experience with their partners require sensibility and professionals involvement. Their main care demands were related to the desire of favorable reception, to get emotional support as well as a whole and correct information about the process.

    1989-01-01

    In view of the application of ionizing radiation to sterilize pharmaceutical products, and the particular advantages of using this mode of sterilization for powders for injection, which cannot be sterilized by more conventional methods, it is important to recognise the possibility of modification of radiation response of bacteria when in close contact with various drug powders. For this study, bacterial spores, which lend themselves to dessication, and which can be dried onto an inert powder matrix, were chosen as the test system. The results of this work indicate that the additives tested have a modest protective effect on the spores. However, when considering a bacterial inactivation for sterilization purposes of between six and ten orders of magnitude, that is, a desired sterility assurance level of an expected maximum probability of a product item being non-sterile of 10 -6 , then the slight protective effect observed in this study approaches insignificance

    Results are presented of a literature review to identify social and psychological aspects of abortion. The literature does not provide a true profile of women requesting abortions, but some characteristics emerge. Reasons for requesting abortion include economic problems, difficult previous pregnancies, general medical contraindications to pregnancy, marital conflicts, feelings of loneliness, professional aspirations, problems with existing children, and feelings of insecurity about the future. However, the same feelings are found among women carrying their pregnancies to term. Unplanned pregnancies are more common during periods of depression. Most authors have found about 1/2 of women seeking abortions to be single and about 1/2 to be under 25 years old. Religion does not appear to be a determining factor. 1 study of psychological factors in abortion seekers found that a large number of single women seeking abortion had suffered traumatic experiences in childhood and were seeking security in inappropriate amorous relationships. Helene Deutsch stressed the destructive impulses latent in all pregnancies. Others have cited the ambivalence of the desire for pregnancy and feelings of loss after abortion. Studies published after legalization of abortion in the US and France however have stressed the nearly total absence of moderate or severe psychiatric symptoms after abortion. Responses immediately after the abortion may include feelings of relief, guilt, indifference, or ambivalence. Secondary affects appear minor to most authors. Psychological effects do not appear to be influenced by age, marital status, parity, intelligence, occupation, existence of a later pregnancy, or concommitant sterilization. "Premorbidity" and coercion by spouse or family were most closely associated with psychological symptoms. Numerous authors have found about twice as many negative reactions among women undergoing abortion for medical reasons. Most patients undergoing abortions for

  2. Abortion ethics.

    Fromer, M J

    Nurses have opinions about abortion, but because they are health professionals and their opinions are sought as such, they are obligated to understand why they hold certain views. Nurses need to be clear about why they believe as they do, and they must arrive at a point of view in a rational and logical manner. To assist nurses in this task, the ethical issues surrounding abortion are enumerated and clarified. To do this, some of the philosophic and historic approaches to abortion and how a position can be logically argued are examined. At the outset some emotion-laden terms are defined. Abortion is defined as the expulsion of a fetus from the uterus before 28 weeks' gestation, the arbitrarily established time of viability. This discussion is concerned only with induced abortion. Since the beginning of recorded history women have chosen to have abortions. Early Jews and Christians forbade abortion on practical and religious grounds. A human life was viewed as valuable, and there was also the practical consideration of the addition of another person to the population, i.e., more brute strength to do the necessary physical work, defend against enemies, and ensure the continuation of the people. These kinds of pragmatic reasons favoring or opposing abortion have little to do with the Western concept of abortion in genaeral and what is going on in the U.S. today in particular. Discussion of the ethics of abortion must rest on 1 or more of several foundations: whether or not the fetus is a human being; the rights of the pregnant woman as opposed to those of the fetus, and circumstances of horror and hardship that might surround a pregnancy. Viability is relative. Because viability is not a specific descriptive entity, value judgments become part of the determination, both of viability and the actions that might be taken based on that determination. The fetus does not become a full human being at viability. That occurs only at conception or birth, depending on one's view

    Skewed male:female ratios at birth have been observed among certain immigrant groups. Data on abortion practices that might help to explain these findings are lacking. We examined 1 220 933 births to women with up to 3 consecutive singleton live births between 1993 and 2012 in Ontario. Records of live births, and induced and spontaneous abortions were linked to Canadian immigration records. We determined associations of male:female infant ratios with maternal birthplace, sex of the previous living sibling(s) and prior spontaneous or induced abortions. Male:female infant ratios did not appreciably depart from the normal range among Canadian-born women and most women born outside of Canada, irrespective of the sex of previous children or the characteristics of prior abortions. However, among infants of women who immigrated from India and had previously given birth to 2 girls, the overall male:female ratio was 1.96 (95% confidence interval [CI] 1.75-2.21) for the third live birth. The male:female infant ratio after 2 girls was 1.77 (95% CI 1.26-2.47) times higher if the current birth was preceded by 1 induced abortion, 2.38 (95% CI 1.44-3.94) times higher if preceded by 2 or more induced abortions and 3.88 (95% CI 2.02-7.50) times higher if the induced abortion was performed at 15 weeks or more gestation relative to no preceding abortion. Spontaneous abortions were not associated with male-biased sex ratios in subsequent births. High male:female ratios observed among infants born to women who immigrated from India are associated with induced abortions, especially in the second trimester of pregnancy. © 2016 Canadian Medical Association or its licensors.

  5. Voluntary sterilization in Serbia: Unmet need?

    2002-01-01

    Full Text Available Is voluntary sterilization as a birth control method accepted in Serbia? This is certainly a question that is being imposed for research, regardless of the fact that voluntary sterilization is neither accessible nor promoted. Most importantly because there is no understanding in the social nor political sphere for legalization of voluntary sterilization as a form of birth control, apart from the clear necessity for this, first, step. They are: the recognition that voluntary sterilization is an efficient and safe birth control method, respectability of basic human as well as sexual and reproductive rights, spreading of sterilization as a form of birth control among population of both developed and developing countries and an epidemic diffusion of repeated induced abortions in Serbia. Thus individual recognition of the advantages of relying on voluntary sterilization, in a non-encouraging atmosphere, certainly represents one more argument to enable couples to prevent conception by sterilization. Since it was impossible to carry out a representative research among the population of men and women who are at risk for conception, an attempt was made to obtain a reply to the set question among women who decided to induce abortion. It was done out of at least two reasons. The first being that women with induced abortion in their reproductive history were the target group for voluntary sterilization. The second reason was based on the assumption that bringing a decision on induced abortion is preceded by the reconsideration of an earlier adopted strategy regarding children, giving birth and contraception and thus its rational component is revealed more and therefore more easily measurable. The research was carried out in the University Clinic of Obstetrics and Gynecology 'Narodni front' in Belgrade from January 21st o March 1st 2002, and included 296 women. By comparing the social and demographic characteristics of the female respondents, as well as

Majority know abortion is legalized and majority have positive attitude about legalization of abortion, however majority are not aware of abortion service in CAC sites and none knew the cost of abortion service. Proper and adequate advocacy of the new abortion law and CAC service is essential.

    Full Text Available Abstract Background The application of hybrid rice technology has significantly increased global rice production during the last three decades. Approximately 90% of the commercially cultivated rice hybrids have been derived through three-line breeding involving the use of WA-CMS lines. It is believed that during the 21st century, hybrid rice technology will make significant contributions to ensure global food security. This study examined the poorly understood molecular basis of the WA-CMS system in rice. Results RFLPs were detected for atp6 and orfB genes in sterile and fertile rice lines, with one copy of each in the mt-genome. The RNA profile was identical in both lines for atp6, but an additional longer orfB transcript was identified in sterile lines. 5' RACE analysis of the long orfB transcript revealed it was 370 bp longer than the normal transcript, with no indication it was chimeric when compared to the genomic DNA sequence. cDNA clones of the longer orfB transcript in sterile lines were sequenced and the transcript was determined unedited. Sterile lines were crossed with the restorer and maintainer lines, and fertile and sterile F1 hybrids were respectively generated. Both hybrids contained two types of orfB transcripts. However, the long transcript underwent editing in the fertile F1 hybrids and remained unedited in the sterile lines. Additionally, the editing of the 1.1 kb orfB transcript co-segregated with fertility restoring alleles in a segregating population of F2 progeny; and the presence of unedited long orfB transcripts was detected in the sterile plants from the F2 segregating population. Conclusion This study helped to assign plausible operative factors responsible for male-sterility in the WA cytoplasm of rice. A new point of departure to dissect the mechanisms governing the CMS-WA system in rice has been identified, which can be applied to further harness the opportunities afforded by hybrid vigor in rice.

    Some evidence has shown a relationship between primary human cytomegalovirus (CMV) infection and pregnancy loss. The impact of CMV infection reactivation during pregnancy on adverse pregnancy outcomes is not completely understood. It is proposed that altered immune response, and therefore, recurrence or reactivation of latent CMV infection may relate to recurrent spontaneous abortion (RSA); however, few data are available in this regard. To find out about any cell mediated defect and reactivation of latent CMV infection in women with RPL, cellular immunity to the virus has been evaluated by specific cytotoxic T lymphocyte (CTL) response to CMV. In a case control study, CTL CD107a expression and in- tercellular IFN-γ production in response to CMV pp65 antigen and staphylococcus enterotoxin B (SEB) in women with RSA were assessed by flow cytometric analysis. Forty-four cases with history of recurrent pregnancy and forty-four controls with history of successful pregnancies were included. The FACSCaliber flow cytometer were used for analysis. No significant difference was observed between CD107a expression and IFN-γ production in response to CMV PP65 antigen in RPL patients and control group. How- ever, the cytotoxic response to SEB antigen in patients with RPL was significantly lower than control group (p=0.042). The results of this study show that impaired CD107a expression and IFN-γ production as CTL response to CMV does not appear to be a major contrib- uting and immune incompetence factor in patients with RPL, but cytotoxic T cell response defect to other antigens requires to be assessed further in these patients.

    Prior to legalization of abortion, induced abortions were performed in an illegal manner and that resulted in many complications hence abortion was legalized in India in 1971 and the number of induced abortions has been gradually increasing since then. One way of preventing abortions is to provide family planning services to these abortion seekers so that same is not repeated. The study was performed to find out the acceptance of contraception after abortion. A prospective study was performed over a period of five years from 2010 to 2014. The study group included all the cases reporting for abortion. A proforma was filled in detail to find out the type of contraception being used before pregnancy and acceptance of contraception after abortion. The existing facilities were also evaluated. 1228 abortions were performed over a period of five years. 94.5% of abortions were during the first trimester. 39.9% had not used any contraceptive before, contraceptives used were natural and barrier which had high failure. The main indication for seeking abortion was failure of contraception and completion of family. 39.6% of patients accepted sterilization as a method of contraception. The existing post abortion family planning services are inadequate. Post abortion period is one which is important to prevent subsequent abortions and family planning services after abortion need to be strengthened.

    The essay discusses abortion in Puerto Rico from 1937 to 1970, concentrating in its legal status as well as its social practice. The research documents the contradictions between the legality of the procedure and a social practice characterized by secrecy. The essay discusses the role of the Clergy Consultation Service on Abortion in promoting the legal practice of absortion in Puerto Rico. It also discusses the ambivalent role of medical doctors who, despite being legally authorized to perform abortions to protect the life and health of women, refused to perform the procedure arguing abortion was illegal. The essay concludes with a brief discussion on perceptions of illegality regarding abortion, emphasizing the contradictions between the practice of abortion and that of sterilization in Puerto Rico.

    Over six million induced abortions were reported in Africa in 2008 with over two million induced abortions occurring in Eastern Africa. Although a significant proportion of women in the region procure more than one abortion during their reproductive period, there is a dearth of research on factors associated with repeat abortion. Data for this study come from the Magnitude and Incidence of Unsafe Abortion Study conducted by the African Population and Health Research Center in Kenya in 2012. The study used a nationally-representative sample of 350 facilities (level II to level VI) that offer post-abortion services for complications following induced and spontaneous abortions. A prospective morbidity survey tool was used by health providers in 328 facilities to collect information on socio-demographic charateristics, reproductive health history and contraceptive use at conception for all patients presenting for post-abortion services. Our analysis is based on data recorded on 769 women who were classified as having had an induced abortion. About 16 % of women seeking post abortion services for an induced abortion reported to have had a previous induced abortion. Being separated or divorced or widowed, having no education, having unwanted pregnancy, having 1-2 prior births and using traditional methods of contraception were associated with a higher likelihood of a repeat induced abortion. The findings point to the need to address the reasons why women with first time induced abortion do not have the necessary information to prevent unintended pregnancies and further induced abortions. Possible explanations linked to the quality of post-abortion family planning and coverage of long-acting methods should be explored.

    We assessed the risk of spontaneous abortion (SA) after inadvertent exposure to HPV-16/18-vaccine during pregnancy using an observational cohort design. The study population included women aged 15-25 years registered with the Clinical Practice Research Datalink General Practice OnLine Database in the United Kingdom (UK), who received at least one HPV-16/18-vaccine dose between 1st September 2008 and 30th June 2011. Exposed women had the first day of gestation between 30 days before and 45 days (90 days for the extended exposure period) after any HPV-16/18-vaccine dose. Non-exposed women had the first day of gestation 120 days-18 months after the last dose. SA defined as foetal loss between weeks 1 and 23 of gestation (UK definition). The frequency of SA was 11.6% (among 207 exposed) and 9.0% (632 non-exposed), women: hazard ratio (HR) adjusted for age at first day of gestation 1.30 (95% confidence interval: 0.79-2.12). Sensitivity analysis per number of doses administered (-30 to +45-day risk period) showed a HR for SA of 1.11 (0.64-1.91) for 18/178 women with one dose during the risk period versus 2.55 (1.09-5.93) in 6/29 women with two doses within a 4-5 weeks period. The proportion of pre-term/full-term/postterm deliveries, small/large for gestational age infants, and birth defects was not significantly different between exposed and non-exposed women. Results were consistent using a (United States) SA definition of foetal loss between weeks 1-19 and/or the extended risk period. There was no evidence of an increased risk of SA and other adverse pregnancy outcomes in young women inadvertently HPV-16/18-vaccinated around gestation. Nevertheless, women who are pregnant or trying to become pregnant are advised to postpone vaccination until completion of pregnancy. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    Full Text Available Abstract Background Corynebacterium aurimucosum is a slightly yellowish, non-lipophilic, facultative anaerobic member of the genus Corynebacterium and predominantly isolated from human clinical specimens. Unusual black-pigmented variants of C. aurimucosum (originally named as C. nigricans continue to be recovered from the female urogenital tract and they are associated with complications during pregnancy. C. aurimucosum ATCC 700975 (C. nigricans CN-1 was originally isolated from a vaginal swab of a 34-year-old woman who experienced a spontaneous abortion during month six of pregnancy. For a better understanding of the physiology and lifestyle of this potential urogenital pathogen, the complete genome sequence of C. aurimucosum ATCC 700975 was determined. Results Sequencing and assembly of the C. aurimucosum ATCC 700975 genome yielded a circular chromosome of 2,790,189 bp in size and the 29,037-bp plasmid pET44827. Specific gene sets associated with the central metabolism of C. aurimucosum apparently provide enhanced metabolic flexibility and adaptability in aerobic, anaerobic and low-pH environments, including gene clusters for the uptake and degradation of aromatic amines, L-histidine and L-tartrate as well as a gene region for the formation of selenocysteine and its incorporation into formate dehydrogenase. Plasmid pET44827 codes for a non-ribosomal peptide synthetase that plays the pivotal role in the synthesis of the characteristic black pigment of C. aurimucosum ATCC 700975. Conclusions The data obtained by the genome project suggest that C. aurimucosum could be both a resident of the human gut and possibly a pathogen in the female genital tract causing complications during pregnancy. Since hitherto all black-pigmented C. aurimucosum strains have been recovered from female genital source, biosynthesis of the pigment is apparently required for colonization by protecting the bacterial cells against the high hydrogen peroxide concentration in

Five (17 per cent) of the 29 women with detected twin pregnancy aborted spontaneously, these are compared...... in at least one sac aborted, while 3 of 20 twin pregnancies with one puncture in each sac aborted (15 per cent). One of 18 (6 per cent) twin pregnancies, where only one sac was punctured, because the twin pregnancies were undetected, aborted. Amniocentesis of both sacs in twin pregnancies seems associated...... with an increased risk of spontaneous abortion. The indications for amniocentesis in twin pregnancies should be critically evaluated....

    Perez Duarte, A E

    1991-01-01

    Analysis of abortion in Mexico from a juridical perspective requires recognition that Mexico as a national community participates in a double system of values. Politically it is defined as a liberal, democratic, and secular state, but culturally the Judeo-Christian ideology is dominant in all social strata. This duality complicates all juridical-penal decisions regarding abortion. Public opinion on abortion is influenced on the 1 hand by extremely conservative groups who condemn abortion as homicide, and on the other hand by groups who demand legislative reform in congruence with characteristics that define the state: an attitude of tolerance toward the different ideological-moral positions that coexist in the country. The discussion concerns the rights of women to voluntary maternity, protection of health, and to making their own decisions regarding their bodies vs. the rights of the fetus to life. The type of analysis is not objective, and conclusions depend on the ideology of the analyst. Other elements must be examined for an objective consideration of the social problem of abortion. For example, aspects related to maternal morbidity and mortality and the demographic, economic, and physical and mental health of the population would all seem to support the democratic juridical doctrine that sees the clandestine nature of abortion as the principal problem. It is also observed that the illegality of abortion does not guarantee its elimination. Desperate women will seek abortion under any circumstances. The illegality of abortion also impedes health and educational policies that would lower abortion mortality. There are various problems from a strictly juridical perspective. A correct definition of the term abortion is needed that would coincide with the medical definition. The discussion must be clearly centered on the protected juridical right and the definition of reproductive and health rights and rights to their own bodies of women. The experiences of other

    We use unique data on abortions performed in New York State from 1971–1975 to demonstrate that women travelled hundreds of miles for a legal abortion before Roe. A100- mile increase in distance for women who live approximately 183 miles from New York was associated with a decline in abortion rates of 12.2 percent whereas the same change for women who lived 830 miles from New York lowered abortion rates by 3.3 percent. The abortion rates of nonwhites were more sensitive to distance than those of whites. We found a positive and robust association between distance to the nearest abortion provider and teen birth rates but less consistent estimates for other ages. Our results suggest that even if some states lost all abortion providers due to legislative policies, the impact on population measures of birth and abortion rates would be small as most women would travel to states with abortion services.

    Most states regulate abortion differently than other health care services. Examples of these regulations include mandating waiting periods and the provision of state-authored information, and prohibiting private and public insurance coverage for abortion. The primary purpose of this paper is to explore abortion patients' perspectives on these regulations. We recruited 20 participants from three abortion providing facilities located in two states in the U.S. South and Midwest. Using a survey and semistructured interview, we collected information about women's knowledge of abortion regulation and policy preferences. During the interviews, women weighed the pros and cons of abortion regulations. We used grounded theory analytical techniques and matrix analysis to organize and interpret the data. We discovered five themes in these women's considerations of regulation: responsibility, empathy, safe and accessible health care, privacy, and equity. Women in the study generally supported policies that they felt protected women or informed decisions. However, most women also opposed laws mandating two-day abortion appointments for women who were traveling long distances. Women tended to favor financial coverage of abortion, arguing that it could help poor women afford abortion or reduce state expenditures. Overall the study participants' opinions on abortion policy reflect key values for advocates and policy makers to consider: responsibility, empathy, safe and accessible health care, privacy, and equity. Future work should examine abortion regulations in light of these shared values. Laws that promote misinformation or prohibit accommodations of unique circumstances are not consistent the positions articulated by the subjects in our study.

    Induced abortion has been legal in India on a broad range of medical and social grounds since 1980s. Often, induced abortion is resorted to as a means for contraception, and has a potential to be misused for sex selective feticide. We assessed the rates, trends, causes and determinants of induced abortions from 2008-12 in a rural community of northern India. Present study is a secondary data analysis of pregnancy outcomes at Ballabgarh Health and Demographic Surveillance System from 2008-12. The data was retrieved from the Health and Management Information System maintained at Ballabgarh. Cause of abortion was self-reported by the women who underwent abortion. Of the 11,102 pregnancies, 1,226 (11%) culminated as abortions of which 425 (3.8%) were induced abortions. Spontaneous abortion rate (7.2%) was twice that of induced abortion rate (3.8%). Both abortion rates had an increasing trend during the course of the study period. Self-reported reasons for opting for induced abortions were bleeding per vaginum (23%), unwanted pregnancy (16%), and unviable fetus diagnosed by ultrasonography (11%). Eight percent of the induced abortions were due to the female sex of the fetus. About 11% of the abortions were performed beyond 20 weeks of gestation which was the upper legal permissible gestational age for performing induced abortions in India. About 10% of the abortions were performed by unqualified practitioners. Caste, wealth index, birth order and size of the village population were the factors that were significantly associated with induced abortion. Though the abortion rate was low, the proportionate contribution of induced abortion was more than what could be expected. Unsafe and sex selective abortion, though illegal, was prevalent. Upper caste and higher socio-economic status families were more likely to opt for induced abortion.

  4. Update on abortion policy.

    To review the status of antiabortion restrictions enacted over the last 5 years in the United States and their impact on abortion services. In recent years, there has been an alarming rise in the number of antiabortion laws enacted across the United States. In total, various states in the union enacted 334 abortion restrictions from 2011 to July 2016, accounting for 30% of all abortion restrictions since the legalization of abortion in 1973. Data confirm, however, that more liberal abortion laws do not increase the number of abortions, but instead greatly decrease the number of abortion-related deaths. Several countries including Romania, South Africa and Nepal have seen dramatic decreases in maternal mortality after liberalization of abortion laws, without an increase in the total number of abortions. In the United States, abortions are incredibly safe with very low rates of complications and a mortality rate of 0.7 per 100 000 women. With increasing abortion restrictions, maternal mortality in the United States can be expected to rise over the coming years, as has been observed in Texas recently. Liberalization of abortion laws saves women's lives. The rising number of antiabortion restrictions will ultimately harm women and their families.

    Full Text Available Many human males produce dysfunctional sperm. Various plants frequently abort pollen. Hybrid matings often produce sterile males. Widespread male sterility is puzzling. Natural selection prunes reproductive failure. Puzzling failure implies something that we do not understand about how organisms are designed. Solving the puzzle reveals the hidden processes of design.

    Background Maternal mortality due to abortion complications stands among the three leading causes of maternal death in Botswana where there is a restrictive abortion law. This study aimed at assessing the patterns and determinants of post-abortion complications. Methods A retrospective institution based cross-sectional study was conducted at four hospitals from January to August 2014. Data were extracted from patients’ records with regards to their socio-demographic variables, abortion complications and length of hospital stay. Descriptive statistics and bivariate analysis were employed. Result A total of 619 patients’ records were reviewed with a mean (SD) age of 27.12 (5.97) years. The majority of abortions (95.5%) were reported to be spontaneous and 3.9% of the abortions were induced by the patient. Two thirds of the patients were admitted as their first visit to the hospitals and one third were referrals from other health facilities. Two thirds of the patients were admitted as a result of incomplete abortion followed by inevitable abortion (16.8%). Offensive vaginal discharge (17.9%), tender uterus (11.3%), septic shock (3.9%) and pelvic peritonitis (2.4%) were among the physical findings recorded on admission. Clinically detectable anaemia evidenced by pallor was found to be the leading major complication in 193 (31.2%) of the cases followed by hypovolemic and septic shock 65 (10.5%). There were a total of 9 abortion related deaths with a case fatality rate of 1.5%. Self-induced abortion and delayed uterine evacuation of more than six hours were found to have significant association with post-abortion complications (p-values of 0.018 and 0.035 respectively). Conclusion Abortion related complications and deaths are high in our setting where abortion is illegal. Mechanisms need to be devised in the health facilities to evacuate the uterus in good time whenever it is indicated and to be equipped to handle the fatal complications. There is an indication for

  9. Trying to prevent abortion.

    It is known that, since antiquity, women confronted with an unwanted pregnancy have used abortion as a means of resolving their dilemma. Although undoubtedly widely used in all historical ages, abortion has come to be regarded as an event preferably avoided because of the impact on the women concerned as well as considerations for fetal life. Policies to reduce numbers and rates of abortion must acknowledge certain observations. Criminalization does not prevent abortion but increases maternal risks. A society's 'openness' in discussing sexual matters inversely correlates with abortion rates. Correlation between contraceptive use and abortion is also inverse but relates most closely to the efficacy of contraceptive methods used. 'Revolution' in the range of contraceptive methods used will have an equivalent impact on abortion rates. Secondary or emergency contraceptive methods have a considerable role to play in the reduction of abortion numbers. Good sex (and 'relationships') education programs may delay sexual debut, increase contraceptive usage and be associated with reduced abortion. Finally, interaction between socioeconomic factors and the choice between abortion and ongoing pregnancy are complex. Abortion is not necessarily chosen by those least able to support a child financially.

    Science.gov (United States)

    Lalli, Chiara

    Abortion has become something to hide, something you can't tell other people, something you have to expiate forever. Besides, abortion is more and more difficult to achieve because of the raising average of consciencious objection (from 70 to 90% of health care providers are conscientious objectors, 2014 data, Ministero della Salute) and illegal abortion is "coming back"from the 70s, when abortion was a crime (Italian law n. 194/1978). Abortion is often blamed as a murder, an unforgivenable sin, even as genocide. Silence against shouting "killers!" to women who are going to have an abortion: this is a common actual scenario. Why is it so difficult to discuss and even to mention abortion?

  11. Two neutral alleles of improving male gamete abortion in indica-japonica hybrid rice

    2000-01-01

    @@It was difficult to use the pronounced heterosis of indica-japonica hybrids rice due to the panicle sterility caused by male and female gamete abortion. The female gamete abortion in most of subspecific hybrids could be solved by using an abortion-neutral gene S5-n, a wide compatibility gene. The problem of male gamete abortion indicated by distorted segregation of marker genes remained to be studied. Segregation distortion via male gamete had been reported on chromosomes 3, 7, 8, 11, and 12.

    Induced abortion is widely practised in Taiwan; however, it had been illegal until 1985. It was of interest to investigate induced abortion practices in Taiwan after its legalization in 1985 in order to calculate the prevalence rate and ratio of induced abortion to live births and to pregnancies in Taiwan. A study using questionnaires through personal interviews was conducted on more than seventeen thousand women who attended a family planning service in Taipei metropolitan areas between 1991 and 1992. The reproductive history and sexual behaviour of the subjects were especially focused on during the interviews. Preliminary findings showed that 46% of the women had a history of having had an induced abortion. Among them, 54.8% had had one abortion, 29.7% had had two, and 15.5% had had three or more. The abortion ratio was 379 induced abortions per 1,000 live births and 255 per 1,000 pregnancies. The abortion ratio was highest for women younger than 20 years of age, for aboriginal women and for nulliparous women. When logistic regression was used to control for confounding variables, we found that the number of previous live births is the strongest predictor relating to women seeking induced abortion. In addition, a significant positive association exists between increasing number of induced abortions and cervical dysplasia.

    To review updates in how abortion care is depicted and analysed though various media outlets: news, television, film, and social media. A surge in recent media-related abortion research has recognized several notable and emerging themes: abortion in the news media is often inappropriately sourced and politically motivated; abortion portrayal in US film and television is frequently misrepresented; and social media has a new and significant role in abortion advocacy. The portrayal of abortion onscreen, in the news, and online through social media has a significant impact on cultural, personal, and political beliefs in the United States. This is an emerging field of research with wide spread potential impact across several arenas: medicine, policy, public health.

    Full text: To diversify the sources of cytoplasmic male sterility for hybrid seed production in rice (Oryza sativa L.) attempts were made to induce this character in a popular indica cultivar PR 106 through chemical mutagens. Seeds were treated with 0.4% ethidium bromide (EB) for 24 or 48h at 10 deg. C, with 0.4% ethyl methanesulphonate (EMS) for 24 or 48h at 10 deg. C for 16 hr at 20 deg. C or with 0.2% streptomycin sulphate (SM) for 24 or 48 hr at 10 deg. C. In M{sub 2} male sterile plants were detected in eleven different progenies, one from SM treatment and the remaining from EMS treatments. All the sterile plants had 100% non-stainable aborted pollen. Seed set upon open-pollination of the male sterile plants with the variety PR 106 ranged from 0.03 to 4.93 per cent whereas no seed formed in bagged panicles. In M{sub 3}, open-pollinated progenies of the male sterile plants and their fertile sibs were further studied. Two progenies segregated for male sterility, all others had only fertile plants. In one of the segregating progenies, five out of six and in the other nine out of fourteen plants were male sterile. The progenies of fertile sibs did not have any male sterile plant. The results indicate that sterility of cytoplasmic type has been induced by EMS. The parental variety PR 106 acts as the maintainer. (author)

    Full Text Available Rice is one of the most important model crop plants whose heterosis has been well exploited in commercial hybrid seed production via a variety of types of male sterile lines. Hybrid rice cultivation area is steadily expanding around the world, especially in Southern Asia. Characterization of genes and proteins related to male sterility aims to understand how and why the male sterility occurs, and which proteins are the key players for microspores abortion. Recently, a series of genes and proteins related to cytoplasmic male sterility, photoperiod sensitive male sterility, self-incompatibility and other types of microspores deterioration have been characterized through genetics or proteomics. Especially the latter, offers us a powerful and high throughput approach to discern the novel proteins involving in male-sterile pathways which may help us to breed artificial male-sterile system. This represents an alternative tool to meet the critical challenge of further development of hybrid rice. In this paper, we reviewed the recent developments in our understanding of male sterility in rice hybrid production across gene, protein and integrated network levels, and also, present a perspective on the engineering of male sterile lines for hybrid rice production.

    to analyze women's perception in relation to their partner's reaction and behavior during the abortion process in two Brazilian capitals, associating the variables from women who suffered a spontaneous abortion with those from women who induced it. semi-structured, questionnaire-based interviews were conducted with 285 women who underwent spontaneous abortion and 31 who reported having induced it. The data were analyzed using the thematic analysis technique, and, subsequently, by the IBM SPSS Statistics Standard Edition software program. The significance level was set at p women who induced an abortion referred to the partner as the person who could not find out about the abortion (pindependence, women still regard male participation in the abortion process as an important factor. The specifics of each capital denote the influence of the geographic and cultural dimension, indicating the need to take into account the particulars of each region in Brazil while considering a holistic approach to women's health.

  18. [Bioethics and abortion. Debate].

    Diniz, D; Gonzalez Velez, A C

    1998-06-01

    Although abortion has been the most debated of all issues analyzed in bioethics, no moral consensus has been achieved. The problem of abortion exemplifies the difficulty of establishing social dialogue in the face of distinct moral positions, and of creating an independent academic discussion based on writings that are passionately argumentative. The greatest difficulty posed by the abortion literature is to identify consistent philosophical and scientific arguments amid the rhetorical manipulation. A few illustrative texts were selected to characterize the contemporary debate. The terms used to describe abortion are full of moral meaning and must be analyzed for their underlying assumptions. Of the four main types of abortion, only 'eugenic abortion', as exemplified by the Nazis, does not consider the wishes of the woman or couple--a fundamental difference for most bioethicists. The terms 'selective abortion' and 'therapeutic abortion' are often confused, and selective abortion is often called eugenic abortion by opponents. The terms used to describe abortion practitioners, abortion opponents, and the 'product' are also of interest in determining the style of the article. The video entitled "The Silent Scream" was a classic example of violent and seductive rhetoric. Its type of discourse, freely mixing scientific arguments and moral beliefs, hinders analysis. Within writings about abortion three extreme positions may be identified: heteronomy (the belief that life is a gift that does not belong to one) versus reproductive autonomy; sanctity of life versus tangibility of life; and abortion as a crime versus abortion as morally neutral. Most individuals show an inconsistent array of beliefs, and few groups or individuals identify with the extreme positions. The principal argument of proponents of legalization is respect for the reproductive autonomy of the woman or couple based on the principle of individual liberty, while heteronomy is the main principle of

    To find the latest and most accurate information on aspects of induced abortion. A literature survey was carried out in which five aspects of abortion were scrutinised: risk to life, risk of breast cancer, risk to mental health, risk to future fertility, and fetal pain. Abortion is clearly safer than childbirth. There is no evidence of an association between abortion and breast cancer. Women who have abortions are not at increased risk of mental health problems over and above women who deliver an unwanted pregnancy. There is no negative effect of abortion on a woman's subsequent fertility. It is not possible for a fetus to perceive pain before 24 weeks' gestation. Misinformation on abortion is widespread. Literature and websites are cited to demonstrate how data have been manipulated and misquoted or just ignored. Citation of non-peer reviewed articles is also common. Mandates insisting on provision of inaccurate information in some US State laws are presented. Attention is drawn to how women can be misled by Crisis Pregnancy Centres. There is extensive promulgation of misinformation on abortion by those who oppose abortion. Much of this misinformation is based on distorted interpretation of the scientific literature.

    Abstract Oral contraceptives (OCs) following induced abortion offer a reliable method to avoid repeated abortion. However, limited data exist supporting the effective use of OCs postabortion. We conducted this systematic review and meta-analysis in the present study reported immediate administration of OCs or combined OCs postabortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, increase endometrial thickness 2 to 3 weeks after abortion, and reduce the risk of complications and unintended pregnancies. A total of 8 major authorized Chinese and English databases were screened from January 1960 to November 2014. Randomized controlled trials in which patients had undergone medical or surgical abortions were included. Chinese studies that met the inclusion criteria were divided into 3 groups: administration of OC postmedical abortion (group I; n = 1712), administration of OC postsurgical abortion (group II; n = 8788), and administration of OC in combination with traditional Chinese medicine postsurgical abortion (group III; n = 19,707). In total, 119 of 6160 publications were included in this analysis. Significant difference was observed in group I for vaginal bleeding time (P = 0.0001), the amount of vaginal bleeding (P = 0.03), and menstruation recovery period (P abortion (P abortion, and reduce the risk of complications and unintended pregnancies.

The ISO standards are voluntary standards which detail both the validation and routine control of the sterilization process. ISO 11137 was approved in 1994 and published in 1995. When reviewing the standard you will note that less than 20% of the standard is devoted to requirements and the remainder is guidance on how to comply with the requirements. Future standards developments in radiation sterilization are being focused on providing additional guidance. The guidance that is currently provided in informative annexes of ISO 11137 includes: device/packaging materials, dose setting methods, and dosimeters and dose measurement, currently, there are four Technical Reports being developed to provide additional guidance: 1. AAMI Draft TIR, 'Radiation Sterilization Material Qualification' 2. ISO TR 13409-1996, 'Sterilization of health care products - Radiation sterilization - Substantiation of 25 kGy as a sterilization dose for small or infrequent production batches' 3. ISO Draft TR, 'Sterilization of health care products - Radiation sterilization Selection of a sterilization dose for a single production batch' 4.

    Both induced and spontaneously arising male sterility mutants exist in a number of important plant species. These mutants are somewhat unique in that they effect procedures for breeding improved varieties. They allow for the possibility of easily obtaining large numbers of hybrids, population breeding systems and the production of hybrid varieties. These mutants are normally classified as cytoplasmic mutants or chromosomal mutants, the latter also being referred to as nuclear or genic mutants. Specific examples of these types of sterility are examined in relation to the breeding system of the species and their potential use for varietal development. Male sterility in diploid and polyploid species is compared, with reference to gene duplication in polyploids. The mechanism of male sterility is examined in the various species at the anatomical and biochemical levels. Methods of isolating male sterility mutants are compared and a specific example is outlined for hexaploid wheat. Future use of male sterility mutants for improving varieties of various crops is examined. (author)

  9. [Demand for abortion. Pre-abortion discussion].

    1994-03-01

    The preabortion interview required by French law takes place between the medical consultation and the aspiration or administration of RU-486. The three marriage counselors at the Center for Social Gynecology in Marseilles have each undertaken a course of personal therapy to enable them to understand their own reactions and motivations as a way of improving their effectiveness with clients. The preabortion interview is an opportunity to listen to and support women who may be experiencing anguish, sadness, ambivalence, or aggressivity. Each client determines the content of the interview. Often the reason for the abortion is given, frequently in terms of economic problems, unemployment, or other justification. The women almost always state that they "cannot", not that they "do not want", to continue the pregnancy, as if external circumstances had made their decision. The decision is usually made with little discussion. Young adolescents are often astounded to find themselves pregnant. Among young girls, the pregnancy may represent an appeal to the parents for attention or understanding. Sometimes the abortion represents a repetition or a reminder of some difficult event in the past, such as a previous abortion or the death of a child. Often the abortion exacerbates problems in the couple's relationship. The mother often experiences rejection of the pregnancy by the father as rejection of herself. Repeat abortions raise questions about whether some aspect of counseling was neglected. The abortion request always occasions a great feeling of guilt, both for being pregnant and for refusing the pregnancy. The interview permits the client to express her feelings and may help her make sense of the experience.

  10. Abortion: a history.

    1985-01-01

    This review of abortion history considers sacred and secular practice and traces abortion in the US, the legacy of the 19th century, and the change that occurred in the 20th century. Abortion has been practiced since ancient times, but its legality and availability have been threatened continuously by forces that would denigrate women's fundamental rights. Currently, while efforts to decrease the need for abortion through contraception and education continue, access to abortion remains crucial for the well-being of millions of women. That access will never be secure until profound changes occur in the whole society. Laws that prohibit absolutely the practice of abortion are a relatively recent development. In the early Roman Catholic church, abortion was permitted for male fetuses in the first 40 days of pregnancy and for female fetuses in the first 80-90 days. Not until 1588 did Pope Sixtus V declare all abortion murder, with excommunication as the punishment. Only 3 years later a new pope found the absolute sanction unworkable and again allowed early abortions. 300 years would pass before the Catholic church under Pius IX again declared all abortion murder. This standard, declared in 1869, remains the official position of the church, reaffirmed by the current pope. In 1920 the Soviet Union became the 1st modern state formally to legalize abortion. In the early period after the 1917 revolution, abortion was readily available in state operated facilities. These facilities were closed and abortion made illegal when it became clear that the Soviet Union would have to defend itself against Nazi Germany. After World War II women were encouraged to enter the labor force, and abortion once again became legal. The cases of the Catholic church and the Soviet Union illustrate the same point. Abortion legislation has never been in the hands of women. In the 20th century, state policy has been determined by the rhythms of economic and military expansion, the desire for cheap

  11. Rewriting abortion: deploying medical records in jurisdictional negotiation over a forbidden practice in Senegal

    Boundary work refers to the strategies deployed by professionals in the arenas of the public, the law and the workplace to define and defend jurisdictional authority. Little attention has been directed to the role of documents in negotiating professional claims. While boundary work over induced abortion has been extensively documented, few studies have examined jurisdictional disputes over the treatment of abortion complications, or post-abortion care (PAC). This study explores how medical providers deploy medical records in boundary work over the treatment of complications of spontaneous and induced abortion in Senegal, where induced abortion is prohibited under any circumstance. Findings are based on an institutional ethnography of Senegal’s national PAC program over a period of 13 months between 2010 and 2011. Data collection methods included in-depth interviews with 36 health care professionals, observation of PAC services at three hospitals, a review of abortion records at each hospital, and a case review of illegal abortions prosecuted by the state. Findings show that health providers produce a particular account of the type of abortion treated through a series of practices such as the patient interview and the clinical exam. Providers obscure induced abortion in medical documents in three ways: the use of terminology that does not differentiate between induced and spontaneous abortion in PAC registers, the omission of data on the type of abortion altogether in PAC registers, and reporting the total number but not the type of abortions treated in hospital data transmitted to state health authorities. The obscuration of suspected induced abortion in the record permits providers to circumvent police inquiry at the hospital. PAC has been implemented in nearly 50 countries worldwide. This study demonstrates the need for additional research on how medical professionals negotiate conflicting medical and legal obligations in the daily practice of treating abortion

    While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated to be about 630 maternal deaths per 100,000 live births. Recent evidences have shown that a major factor in this trend is the high incidence of abortion in the country. The objective of this paper is, therefore, to investigate the factors determining the demand for abortion and post-abortion care in Ibadan city of Nigeria. The study employed data from a hospital-based/exploratory survey carried out between March to September 2010. Closed ended questionnaires were administered to a sample of 384 women of reproductive age from three hospitals within the Ibadan metropolis in South West Nigeria. However, only 308 valid responses were received and analysed. A probit model was fitted to determine the socioeconomic factors that influence demand for abortion and post-abortion care. The results showed that 62% of respondents demanded for abortion while 52.3% of those that demanded for abortion received post-abortion care. The findings again showed that income was a significant determinant of abortion and post-abortion care demand. Women with higher income were more likely to demand abortion and post-abortion care. Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers' education was only statistically significant in determining abortion demand but not post-abortion care demand. The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this in the absence of proper post-abortion

    Cervical abortion is a spontaneous abortion of an intrauterine pregnancy into the cervical canal where the abortus is retained by a closed external os, causing distension of the cervical canal. Cervical abortion should be distinguished from the cervical pregnancy. We present a case of cervical abortion diagnosed preoperatively by transvaginal sonography and color doppler imaging, and treated by dilatation and curettage. Charateristic transvaginal sonographic findings and identification of subtrophoblastic blood flow by color doppler imaging could allow differentiation of the cevical aborition from the cervical pregnancy

    Full Text Available OBJECTIVE: To assess the Outcome of pregnancy in patients with threatened abortion. METHODS: A Prospective observational study was done on 106 pregnant women with threatened abortion. Out comes in the form of antenatal complications, mode of delivery and postnatal co mplications were noted. Analysis of the data was done using SPSS version 13. RESULTS: In the study of 106 patients 18% had spontaneous abortion. Pre - labour rupture of membranes were seen in 20% of patients and 21% had preterm labour. Threatened abortion di d not affect mode of delivery. PPROM, preterm births were more in women presenting with first trimester bleeding; PIH, PROM, and postpartum complications were more in women presenting beyond 20 weeks gestation though statistically not significant. 13.2% of women had heavy bleeding at admission out of which 50% aborted subsequently – significantly higher than the light bleeding group. CONCLUSION: The overall maternal and perinatal outcome in women with threatened abortion is suboptimal. Women with heavy blee ding are more likely to abort than women with light bleeding. Among the prognostic factors, only the amount of bleeding had significant prognostic accuracy

  20. Post abortion syndrome?

    Science.gov (United States)

    1987-12-01

    There is general agreement that uncertainty persists regarding the psychological sequelae of abortion. Inconsistencies of interpretation stem from a lack of consensus about the symptoms, severity, and duration of mental disorder. In addition, opinions differ based on individual case studies and there is no national reporting system or adequate follow up system. Frequently, reviews combine studies conducted prior to and after the 1973 Supreme Court decision, mix elective abortion with those induced for medical reasons, or fail to distinguish between abortions performed early or late in gestation. The literature reveals methodological problems, a lack of controls, and sampling inadequacies. A review of the available literature and the files of "Abortion Research Notes" suggests that women at particular risk for postabortion stress reactions are those who terminate an originally wanted pregnancy, are strongly ambivalent, come very late in their pregnancy, or lack the support of significant others.

    The book presents a survey of the principles of cold sterilization by radiation or gas, and also of the problems involved. The reader who has to do with sterilization of some kind or other, as e.g. sterilization of medicaments, medical supplies, medical device, drugs, grafts, or food, will find comprehensive information on the various available methods and their effects, as well as on monitoring procedures and techniques, together with proposals for efficient documentation and validation of partial sterilization processes. The introduction summarizes the potentials of sterilization by radiation, and the subsequent by radiation, and the subsequent chapters explain the specific applicabilities of radiosterilization along with the most important criteria for evaluating the sterilizing efficiency. The information on the legal situation and requirements takes into account the second amendment of the Medical Preparations Act. With 38 figs., 14 tabs [de

    Accurate measurement of induced abortion levels has proven difficult in many parts of the world. Health care workers and policymakers need information on the incidence of both legal and illegal induced abortion to provide the needed services and to reduce the negative impact of unsafe abortion on women's health. Numbers and rates of induced abortions were estimated from four sources: official statistics or other national data on legal abortions in 57 countries; estimates based on population surveys for two countries without official statistics; special studies for 10 countries where abortion is highly restricted; and worldwide and regional estimates of unsafe abortion from the World Health Organization. Approximately 26 million legal and 20 million illegal abortions were performed worldwide in 1995, resulting in a worldwide abortion rate of 35 per 1,000 women aged 15-44. Among the subregions of the world, Eastern Europe had the highest abortion rate (90 per 1,000) and Western Europe to the lowest rate (11 per 1,000). Among countries where abortion is legal without restriction as to reason, the highest abortion rate, 83 per 1,000, was reported for Vietnam and the lowest, seven per 1,000, for Belgium and the Netherlands. Abortion rates are no lower overall in areas where abortion is generally restricted by law (and where many abortions are performed under unsafe conditions) than in areas where abortion is legally permitted. Both developed and developing countries can have low abortion rates. Most countries, however, have moderate to high abortion rates, reflecting lower prevalence and effectiveness of contraceptive use. Stringent legal restrictions do not guarantee a low abortion rate.

  3. Inherited sterility in insects

    The unique genetic phenomena responsible for inherited sterility (IS) in Lepidoptera and some other arthropods, as compared with full sterility, provide advantages for pest control. Lepidopteran females are usually more sensitive to radiation than males of the same species. This allows the radiation dose to be adjusted to suit programme requirements. When partially sterile males mate with wild females, the radiation-induced deleterious effects are inherited by the F 1 generation. As a result, egg hatch is reduced and the resulting offspring are both highly sterile and predominately male. Compared with the high radiation required to achieve full sterility in Lepidoptera, the lower dose of radiation used to induce F 1 sterility increases the quality and competitiveness of the released insects as measured by improved dispersal after release, increased mating ability, and superior sperm competition. F 1 sterile progeny produced in the field enhance the efficacy of released partially sterile males, and improve compatibility with other pest control strategies. In addition, F 1 sterile progeny can be used to increase the production of natural enemies, and to study the potential host and geographical ranges of exotic lepidopteran pests. (author)

  4. Catholic attitudes toward abortion.

    Science.gov (United States)

    Smith, T W

    1984-01-01

    In the US attitudes toward abortion in the 1980s seem to have reached a more liberal plateau, much more favored than in the 1960s or earlier, but not longer moving in a liberal direction. Catholic attitudes basically have followed the same trend. Traditionally Catholic support has been slightly lower than Protestant, and both are less inclined to support abortion than Jews or the nonreligious. During the 1970s support among non-black Catholics averaged about 10 percentage points below non-black Protestants. Blacks tend to be anti-abortion and thereby lower support among Protestants as a whole. A comparison of Protestants and Catholics of both races shows fewer religious differences -- about 7 percentage points. There are some indications that this gap may be closing. In 1982, for the 1st time, support for abortions for social reasons, such as poverty, not wanting to marry, or not wanting more children, was as high among Catholics as among Protestants. 1 of the factors contributing to this narrowing gap has been the higher level of support for abortion among younger Catholics. Protestants show little variation on abortion attitudes, with those over age 65 being slightly less supportive. Among Catholics, support drops rapidly with age. This moderate and possibly vanishing difference between Catholics and Protestants contrasts sharply with the official positions of their respective churches. The Catholic Church takes an absolute moral position against abortion, while most Protestant churches take no doctrinaire position on abortion. Several, such as the Unitarians and Episcopalians, lean toward a pro-choice position as a matter of social policy, though fundamentalist sects take strong anti-abortion stances. Few Catholics agree with their church's absolutist anti-abortion position. The big split on abortion comes between what are sometimes termed the "hard" abortion reasons -- mother's health endangered, serious defect in fetus, rape, or incest. Support among Catholics

    Roe v. Wade was heralded as an end to unequal access to abortion care in the United States. However, today, despite being common and safe, abortion is performed only selectively in hospitals and private practices. Drawing on 61 interviews with obstetrician-gynecologists in these settings, we examine how they determine which abortions to perform. We find that they distinguish between more and less legitimate abortions, producing a narrative of stratified legitimacy that privileges abortions for intended pregnancies, when the fetus is unhealthy, and when women perform normative gendered sexuality, including distress about the abortion, guilt about failure to contracept, and desire for motherhood. This stratified legitimacy can perpetuate socially-inflected inequality of access and normative gendered sexuality. Additionally, we argue that the practice by physicians of distinguishing among abortions can legitimate legislative practices that regulate and restrict some kinds of abortion, further constraining abortion access. © American Sociological Association 2016.

  7. Unsafe abortion: the silent scourge.

    2003-01-01

    An estimated 19 million unsafe abortions occur worldwide each year, resulting in the deaths of about 70,000 women. Legalization of abortion is a necessary but insufficient step toward improving women's health. Without skilled providers, adequate facilities and easy access, the promise of safe, legal abortion will remain unfulfilled, as in India and Zambia. Both suction curettage and pharmacological abortion are safe methods in early pregnancy; sharp curettage is inferior and should be abandoned. For later abortions, either dilation and evacuation or labour induction are appropriate. Hysterotomy should not be used. Timely and appropriate management of complications can reduce morbidity and prevent mortality. Treatment delays are dangerous, regardless of their origin. Misoprostol may reduce the risks of unsafe abortion by providing a safer alternative to traditional clandestine abortion methods. While the debate over abortion will continue, the public health record is settled: safe, legal, accessible abortion improves health.

  8. On the Wrongfulness of abortion

    2017-07-01

    Full Text Available Abortion is seen as an immoral and unjust act by many. Nonetheless these views are under pressure to conform to the learned opinion on abortion. A variety of prestigious in the field of applied ethics support abortion in one way or another. And it is a dogma of modern liberalism that even if one is personally opposed to abortion, one must accept the neutral solution of its public permissibility. The present article defends the thesis that abortion is immoral and unjust against these contentions. With regards to the moral status of abortion, it argues that the prohibition of abortion is off a piece with the prohibition of killing generally, which is characterized by protecting all human beings equally. With regards to the compatibility of abortion permissibility with liberalism, the article argues that such a compromise is not neutral, but heavily rigged in favor of the interests and world-views of abortion proponents.

    The discussion considers the current status of reversibility of sterilization in the US and describes clinical and experimental efforts for developing techniques designed for reversibility. It focuses on regret following sterilization, reversal potential of current sterilization techniques, patient selection, current reversal techniques, results of sterilization procedures, experimental approaches to reversal of current techniques of sterilization, and sterilization procedures devised for reversibility, in humans and in animals. Request is the 1st stage of reversal, but a request for sterilization reversal (SR) does not always mean regret for a decision made at the time. Frequently it is a wish to restore fertility because life circumstances have changed after a sterilization that was ppropriate at the time it was performed. Schwyhart and Kutner reviewed 22 studies published between 1949-69 in which they found that the percentage of patients regretting the procedure ranged from 1.3-15%. Requests for reversal remain low in most countries, but if sterilization becomes a more popular method of contraception, requests will also increase. The ideal operation considered as a reversaible method of sterilization should include an easy, reliable outpatient method of tubal occlusion with miniml risk or patient discomfort that subsequently could be reversed without the need for a major surgical intervention. Endoscopic methods have progressed toward the 1st objective. A recent search of the literature uncovered few series of SR of more than 50 cases. The 767 operations found were analyzed with regard to pregnancy outcome. The precent of live births varied from 74-78.8%, and the occurance of tubal pregnancies ranged from 1.7-6.5%. All of the confounding variables in patient selection and small numbers of reported procedures preclude any conclusion about the different techniques or the number of operations that give a surgeon a level of expertise. Few authors classify their

    The prevalence of domestic violence and abortion in India is high, yet little is known about the relationship between these experiences. Data from two linked data sets, India's 1998-1999 National Family Health Survey (NFHS-2) and a follow-up survey in 2002-2003, were analyzed. The analysis examines how the experience of physical violence affects the subsequent uptake of abortion, and how the experience of abortion affects subsequent experience of physical, sexual, and verbal violence. Women who experienced physical violence have significantly higher odds of reporting a subsequent induced abortion, whereas women who had an induced abortion have significantly higher odds of reporting subsequent sexual and verbal violence. There was no significant relationship between domestic violence and spontaneous abortion. © The Author(s) 2016.

  11. Late induced abortion.

    Science.gov (United States)

    Savage, W

    1990-09-01

    In the UK in 1988, 13.3% of abortions were performed at 13 weeks' gestation or later. Reasons for this delay, in addition to the diagnosis through amniocentesis of a fetal abnormality, include late recognition of pregnancy, a change of mind about completing the pregnancy, a failure of primary care physicians to entertain the diagnosis of pregnancy, travel or financial problems, and referral difficulties and scheduling delays. Women with little education and very young women are most likely to present for late abortions. From 13-16 weeks, dilatation and evacuation is the safest method of pregnancy termination. The procedure can be made easier through preparation of the cervix with a prostaglandin pessary or Foley catheter. After 16 weeks, an instillation method is recommended; prostaglandin administration can be intro- or extra-amniotic. Complication rates at 13-19 weeks are 14.5/1000 for vaginal methods of abortion and 7.2/1000 for prostaglandin methods. The risk of complications is 3 times higher for women who have 2nd-trimester abortions through the National Health Service. Although it is not realistic to expect that late abortions ever can be eliminated, improved sex education and contraceptive reliability as well as reforms in the National Health Service could reduce the number substantially. To reduce delay, it is suggested that the National Health Service set up satellite day care units and 1-2 central units in each region to deal quickly with midtrimester abortions. Delays would be further reduced by legislation to allow abortion on request in at least the 1st trimester of pregnancy.

    Pollens of Sumian 22 were irradiated by 60 Co γ-rays at a dose of 20Gy, then fertilized to pistil and harvested seed. Three male-sterile lines were selected from M 1 plants, their anther observed by paraffin slice technique. Although there were some different characteristics during the abortion anther development, the abortion was consistent: the abortion stage from the development periods of pollen mother cells to microspore, pollen mother cells, tapetum, middle layer cells and the shape of anther were affected, the results contained micronucleus and double nucleus, cytoplasm expansion during the period of meiosis, tapetum and middle layer cells and so on were abnormal.

    In Papua New Guinea abortion is restricted under the Criminal Code Act. While safe abortions should available in certain situations, frequently they are not available to the majority of women. Sepsis from unsafe abortion is a leading cause of maternal mortality. Our findings form part of a wider, mixed methods study designed to identify complications requiring hospital treatment for post abortion care and to explore the circumstances surrounding unsafe abortion. Through a six month prospective study we identified all women presenting to the Eastern Highlands Provincial Hospital following spontaneous and induced abortions. We undertook semi-structured interviews with women and reviewed individual case notes, extracting demographic and clinical information. Case notes were reviewed for 56% (67/119) of women presenting for post abortion care. At least 24% (28/119) of these admissions were due to induced abortion. Women presenting following induced abortions were significantly more likely to be younger, single, in education at the time of the abortion and report that the baby was unplanned and unwanted, compared to those reporting spontaneous abortion. Obtained illegally, misoprostol was the method most frequently used to end the pregnancy. Physical and mechanical means and traditional herbs were also widely reported. In a country with a low contraceptive prevalence rate and high unmet need for family planning, all reproductive age women need access to contraceptive information and services to avoid, postpone or space pregnancies. In the absence of this, women are resorting to unsafe means to end an unwanted pregnancy, putting their lives at risk and putting an increased strain on an already struggling health system. Women in this setting need access to safe, effective means of abortion.

    Significant changes are shown to occur in the level of sex hormones in blood at the risk of spontaneous abortion, missed abortion, or the mole. Determining the levels of estradiol, progesterone, chorial gonadotropin and testosterone in the blood serum using RIA yields immediate information on the hormonal function of the fetoplacental unit. This has diagnostic significance and can be used as a criterion for the application of complementary hormonal therapy when there is a risk of abortion or premature delivery. (author)

  17. [Abortion: towards worldwide legalization].

    Science.gov (United States)

    1998-09-01

    A table showing the current status of abortion in the world based on two recent and detailed studies is presented. Countries are categorized according to whether they totally prohibit abortion, permit it to save the mother's life, permit it to preserve her physical health or mental health, permit it for maternal socioeconomic reasons, or provide it at the mother's request. The countries are grouped into 5 geographic areas: America and the Caribbean; Central Asia, Middle East, and North Africa; East and South Asia and the Pacific; Europe; sub-Saharan Africa. The trend toward liberalization of laws is clear. The development of abortion laws is moving in the direction of complete legalization, that is, the creation of health norms that facilitate abortion for all women, with guarantees of medical safety. There are still countries that move to restrict access to abortion, and in a few cases, such as Colombia and Poland, legalization and prohibition have alternated depending on the social and political circumstances of the moment. In the past 12 years, 28 countries liberalized their laws in some way, while 4 countries with close ties to the Vatican restricted or prohibited access.

  18. Jewish views on abortion.

    Science.gov (United States)

    Jakobovits, I

    1968-01-01

    In Jewish law right and wrong, good and evil, are absolute values which transcend time, place, and environment. They defy definition by human intuition or expediency. Jewish law derives from the Divine revelation at Mount Sinai as expounded by sages faithful to, and authorized by, its writ. The Talmud rules that if a woman is in hard travail, and her life must be saved, the child must be aborted and extracted. The mother's life comes first. The fetus is not a human life until it is born. But 19th century Rabbinical works state that it is immoral to destroy a monster child. Modern rabbis are unanimous in condemning abortion, feticide, or infanticide as an unconscionable attack on human life. However, Jewish law allows abortion if the pregnancy will cause severe psychological damage to the mother. No civilized society could survive without laws which occasionally cause some suffering or personal anguish. One human life is worth a million lives, because each life is infinite in value. In cases of rape or incest Jewish law still does not sanction abortion. Man's procreative responsibilities are serious and carry rights and obligations which would be upset by liberalized abortion laws. If a person kills a person who is mortally wounded, the killer is guilty of a moral offense.

  19. Defining minors' abortion rights.

    Science.gov (United States)

    Rhodes, A M

    1988-01-01

    The right to abortion is confirmed in the Roe versus Wade case, by the US Supreme Court. It is a fundamental right of privacy but not an absolute right, and must consider state interests. During the first trimester of pregnancy abortion is a decision of the woman and her doctor. During the second trimester of pregnancy the state may control the abortion practice to protect the mothers health, and in the last trimester, it may prohibit abortion, except in cases where the mother's life or health are in danger. The states enacted laws, including one that required parents to give written consent for a unmarried minor's abortion. This law was struck down by the US Court, but laws on notification were upheld as long as there was alternative procedures where the minor's interests are upheld. Many of these law have been challenged successfully, where the minor was judged mature and where it served her best interests. The state must enact laws on parental notification that take into consideration basic rights of the minor woman. Health professionals and workers should be aware of these laws and should encourage the minor to let parents in on the decision making process where possible.

    Full Text Available Introduction: - The biological definition of miscarriage is the expulsion of the conceptus before viability has been achieved. The definition of recurrent miscarriage is three or more consecutive spontaneous abortions. The risk factors for recurrent miscarriage are epidemiological, genetic, anatomical disorders, endocrinal, reproductive tract infections, thrombophilic disorders, disorders of materno-fetal alloimmune relationships, environmental effects and psychological causes. About 50% to 60% of all first trimester abortions are associated with derangement of one or more chromosomal complements. Aim: - The aim of this study was to assess frequency and increasing the awareness of physician about the nature of chromosomal aberration that contribute to the occurrence of repeated abortions. Material & Methods: - Patient of recurrent abortion was investigated by history taking, examination and investigations. For present study 20 women having two or more consecutive spontaneous abortions, who attended outdoor & indoor patient department, were selected and karyotyping was done. In 10 of the above cases karyotype study of both partners was done. So in total 30 individuals (20 females & 10 males were selected for Cytogenetic study. In all cases relevant history and clinical findings and other investigations were noted. Blood samples were obtained and karyotype study was performed at Genetic Laboratory, B. J. Medical College, Ahmedabad. Results and Conclusions: - Cytogenetic evaluation by karyotypes revealed robertsonian translocation in one (5% female; this patient had a history of 2 spontaneous abortions and two times IVF failure, she had history of chocolate cyst of ovary and family history of infertility. No numerical anomaly; mosaicism or inversions were found in this study; 23 cases had normal karyotype and remaining 6 cases came out inconclusive.

    To establish an effective and safe clinical fertility strategy by investigating the relationship between abortion history and pregnancy outcomes of in vitro fertilization (IVF) treatment. In the present retrospective cohort study, data from IVF treatment cycles performed at a reproductive center in China between October 1, 2014, and October 31, 2015, were assessed. Outcomes were compared between women with a history of induced abortion and those without. There were 1532 IVF treatment cycles included; 454 patients had a history of induced abortion and 1078 did not. The spontaneous abortion rate was significantly higher (30/170 [17.6%] vs 41/420 [9.8%]; P=0.002) and the endometrium was significantly thinner (8.8 ± 1.8 vs 9.7 ± 1.8 cm; P=0.001) among patients with a history of induced abortion compared with those without. In a subgroup analysis of patients with a history of induced abortion, women who had undergone surgical abortions had a lower live delivery rate compared with medical abortions (29/76 [38%] vs 101/378 [27%]; P=0.039). Further, women who had a history of more than two surgical abortions had lower live delivery and clinical pregnancy rates (both Pabortion was associated with worse IVF outcomes, especially a history of more than two surgical abortions. © 2018 International Federation of Gynecology and Obstetrics.

    In this article we address the issue, with a tentative empirical application to the Italian data, of the relationship, very debated mainly in north America, between abortion legalization and reduction of crime rates of youth. The rationale of this relationship is that there is a causal factor at work: the more unwanted pregnancies aborted, the less unwanted children breeding their criminal attitude in an hostile/deprived family environment. Many methodological and empirical criticisms have been raised against the proof of the existence of such a relationship: our attempt to test if this link is valid for Italy cannot endorse its existence. The data we used made necessary some assumptions and the reliability of official estimates of crime rates was debatable (probably downward biased). We conclude that, at least for Italy, the suggested relationship is unproven: other reasons for the need of legal abortion have been and should be put forward.

    To assess the contraceptive information received and methods chosen, received, and used among women having abortions one decade after legalization of abortion in Nepal. We examined postabortion contraception with questionnaires at baseline and six months among women obtaining legal abortions (n=838) at four facilities in 2011. Multivariate regression analysis was used to measure factors associated with method information, choice, receipt, and use. One-third of participants received no information on effective methods, and 56% left facilities without a method. The majority of women who chose to use injectables and pills were able to do so (88% and 75%, respectively). However, only 44% of women choosing long-acting reversible contraceptives and 5% choosing sterilization had initiated use of the method by six months. Levels of contraceptive use after medical abortion were on par with those after aspiration abortion. Nulliparous women were far less likely than parous women to receive information and use methods. Women living without husbands or partners were also less likely to receive information and supplies, or to use methods. Improvements in postabortion counseling and provision are needed. Ensuring that women choosing long-acting and permanent contraceptive methods are able to obtain either them or interim methods is essential.

  7. On being a certifying abortion consultant: an ethical dilemma.

    Science.gov (United States)

    Clarkson, S E

    1980-05-14

    The medical profession was relieved when the Contraceptive, Sterilization and Abortion Act was passed in New Zealand in 1977, but it now appears that there are continuing problems with the implementation of the law. Most of the law's clauses are concerned with the practical aspects of the performance of abortions in New Zealand. Outlined in the law are requirements for licenses of hospitals, certifying consultants and operating surgeons, and the tasks of the supervising committee are specified. Thus, the medical profession accepted the impossible job of becoming the arbiter of morals of New Zealand society. There have been problems, since passage of the law, with inadequate numbers of certifying consultants being recruited, the resignation of the chair of the Abortion Supervisory Committee, a lack of resources to provide the required counseling services, and local variation in interpretations resulting in inconsistent treatment of abortion requests in different parts of the country. The basis of the problem is the fact that this law requires a moral rather than a medical decision to be made. Although at 1st glance the phrase serious risk to mental health would appear to be easily interpreted, this is not so. The morality of an act of abortion depends on the right afforded the fetus, and no society has as yet achieved a consensus on this. Thus, this must remain the conviction of each separate individual. Some guidance may come from medidal and legal advisers in this moral decision, but it is impossible to delegate personal moral decisions.

    The term "eugenics" was coined by Francis Galton in 1883 and was defined as the science of the improvement of the human race by better breeding. "Positive eugenics" referred to methods of encouraging the "most fit" to reproduce more often, while "negative eugenics" was related to ways of discouraging or preventing the "less fit" from reproducing by birth control and sterilization. Many western countries adopted eugenics programs including Britain, Canada, Norway, Australia, Switzerland and others. In Sweden more then 62,000 "unfits" were forcibly sterilized. Many states in the U.S.A. had adopted marriage laws with eugenics criteria including forced sterilization. Approximately 64,000 individuals were sterilized. Eugenics considerations also lay behind the adoption of the Immigration Restriction Act of 1924. The Largest plan on eugenics was adopted by the Nazi regime in Germany. Hundreds of thousands of people, who were viewed as being "unfit", were forcibly sterilized by different methods: Surgical sterilization or castration with severe complications and high mortality rates. X-ray irradiation. The method was suggested by Brack, and tested by Schuman using prisoners in Block No. 10 in Auschwitz and Birkenau. Experiments were also performed by Brack on prisoners using the "window method". "Klauberg method"--injection of irritating materials into the uterus. Experiments were conducted using the plant Caladium Seguinum which was believed to have sterilization and castration properties.

    By using the technology of microscopy,electron microscopy and enzyme cytochemical localization, comparison was made of the cytomorphology, ATPase and cytochrome oxidase activity in pollens during microspore formation and pollen development, for K-type cytoplasmic male sterile (CMS) lines, T-type CMS lines and their maintainer lines on wheat. The results indicated that pollen abortion of the T-type CMS lines mainly occurred at the later mononucleate pollen stage, and cytomorphological changes of the abortive pollen began with a vacuolar membrane, and pollen aborting was related to a lack of ATPase activity in the nucleus and nucleolus during the mononucleate pollen stage. Pollen abortion of the K-type CMS lines took place mainly during the later binucleate and trinucleate stages, and cytomorphological changes of the abortion first began with mitochondria. The abortion was related to intine disruption.

    Sterilization in Yugoslavia is no population policy measure. Decision about the birth of children is free, a private problem of any individual, a basic right guaranteed by the Constitution. However, according to certain laws in Slovenia and Croatia, sterilization is allowed as a family planning method in persons over 35 year old. Only exceptionally can sterilization be applied in persons younger than 35 years: according to the Slovenian law, in cases when a person lacks the capacity of reasoning and also when there are medical indications, and according to the Croatian law, when there are medical and eugenic reasons (if the child is supposed to be born with negative congenital properties).

    A question of great interest in sterile and clean room technology is how can we devise a standard for the guarantee of sterility? Sterility is of widespread importance: it gives the life-time of our daily milk or yogurt, dominates the nature of food packing, and determines the feasibility of the miniaturization of biotechnology plants. All these phenomena are based on the principle of bioadhesion. Bioadhesion is also the basis of the biomimetic material technologies, like the attachment of selected protein layers that can be used for nanomasking. (orig.)

    The intersubspecific hybrids of autotetraploid rice has many features that increase rice yield, but lower seed set is a major hindrance in its utilization. Pollen sterility is one of the most important factors which cause intersubspecific hybrid sterility. The hybrids with greater variation in seed set were used to study how the F(1) pollen sterile loci (S-a, S-b, and S-c) interact with each other and how abnormal chromosome behaviour and allelic interaction of F(1) sterility loci affect pollen fertility and seed set of intersubspecific autotetraploid rice hybrids. The results showed that interaction between pollen sterility loci have significant effects on the pollen fertility of autotetraploid hybrids, and pollen fertility further decreased with an increase in the allelic interaction of F(1) pollen sterility loci. Abnormal ultra-structure and microtubule distribution patterns during pollen mother cell (PMC) meiosis were found in the hybrids with low pollen fertility in interphase and leptotene, suggesting that the effect-time of pollen sterility loci interaction was very early. There were highly significant differences in the number of quadrivalents and bivalents, and in chromosome configuration among all the hybrids, and quadrivalents decreased with an increase in the seed set of autotetraploid hybrids. Many different kinds of chromosomal abnormalities, such as chromosome straggling, chromosome lagging, asynchrony of chromosome disjunction, and tri-fission were found during the various developmental stages of PMC meiosis. All these abnormalities were significantly higher in sterile hybrids than in fertile hybrids, suggesting that pollen sterility gene interactions tend to increase the chromosomal abnormalities which cause the partial abortion of male gametes and leads to the decline in the seed set of the autotetraploid rice hybrids. © 2011 The Author(s).

    Radiation sterilization is the best method of sterilization, essentially for single use medical and surgical products. Pakistan has established a commercial gamma irradiation plant for this purpose. This article overviews the advantages and benefits of radiation sterilization to stimulate the interest of industrialists and the users in this technology. This technology can give a better medical care in the country and the growing demand can only be met by bulk sterilization. The radiation sterilized medical products can also compete well with the products sterilized by other methods in the international market, gamma sterilization is accepted internationally and if adopted it can boost our export of medical products.

    The radiation sterilization of livestock feeds is not much used presently because the process is not known well, and the cost is relatively high. However, its effect of sterilization is absolute, the radiation-sterilized feeds are safe in both nutrition and toxicity, and do not affect the appetite of livestocks, and the radiation energy required is small. In the future, as in the sterilization of medical supplies, feed radiation sterilization plants should be established, to stabilize livestock industry and to contribute to the health control of experimental animals. The following matters are described: radiation, comparison between radiation sterilization and other sterilization methods, the practice of feed radiation sterilization, the adverse effects of radiation sterilization, economic aspect, and the situation of feed radiation sterilization in various countries.

  8. Transcriptomic Profiling Reveals Complex Molecular Regulation in Cotton Genic Male Sterile Mutant Yu98-8A.

    Directory of Open Access Journals (Sweden)

    Weiping Fang

    Full Text Available Although cotton genic male sterility (GMS plays an important role in the utilization of hybrid vigor, its precise molecular mechanism remains unclear. To characterize the molecular events of pollen abortion, transcriptome analysis, combined with histological observations, was conducted in the cotton GMS line, Yu98-8A. A total of 2,412 genes were identified as significant differentially expressed genes (DEGs before and during the critical pollen abortion stages. Bioinformatics and biochemical analysis showed that the DEGs mainly associated with sugars and starch metabolism, oxidative phosphorylation, and plant endogenous hormones play a critical and complicated role in pollen abortion. These findings extend a better understanding of the molecular events involved in the regulation of pollen abortion in genic male sterile cotton, which may provide a foundation for further research studies on cotton heterosis breeding.

    Full text: In 1973, a photoperiod-sensitive genic male-sterile plant was discovered in Nongken 58. It is male sterile under long day conditions and fertile under short day conditions. Under the natural photoperiod in Wuhan, plants heading before September 2 are male sterile, showing typical pollen abortion. The fertility is gradually restored after September 2. About 50% of pollen grains are normal after September 6. F 1 using 30 different varieties was fertile regardless of daylength, F 2 segregated into 3 fertile: 1 sterile types under long day condition in some crosses, less clearly in other crosses. It is concluded that photoperiod depending male sterility is monogenic recessive inherited with some influence of modifier genes. Any normal variety can be used as restorer, therefore strong heterosis combinations can easily be bred. (author)

  10. Religion and attitudes toward abortion and abortion policy in Brazil.

    This study examines the association between religion and attitudes toward the practice of abortion and abortion policy in Brazil. Drawing upon data from the 2002 Brazilian Social Research Survey (BSRS), we test a number of hypotheses with regard to the role of religion on opposition to the practice of abortion and its legalization. Findings indicate that frequently attending Pentecostals demonstrate the strongest opposition to the practice of abortion and both frequently attending Pentecostals and Catholics demonstrate the strongest opposition to its legalization. Additional religious factors, such as a commitment to biblical literalism, were also found to be significantly associated with opposition to both abortion issues. Ultimately, the findings have implications for the future of public policy on abortion and other contentious social issues in Brazil.

    The field of abortion counseling originated in the abortion rights movement of the 1970s. During its evolution to the present day, it has faced significant challenges, primarily arising from the increasing politicization and stigmatization of abortion since legalization. Abortion counseling has been affected not only by the imposition of antiabortion statutes, but also by the changing needs of patients who have come of age in a very different era than when this occupation was first developed. One major innovation--head and heart counseling--departs in significant ways from previous conventions of the field and illustrates the complex and changing political meanings of abortion and therefore the challenges to abortion providers in the years following Roe v Wade.

  12. Male sterility in chestnuts

    1982-01-01

    A tentative plan was proposed for chestnuts based on their pollination system, male sterility and restoration. The studies on the male sterility of 1,063 cultivars and clones suggested that there were three types of male sterility. The first type (S-1) was characterized by antherless florets. In the second type (S-2), the catkins fell before anthesis, and the third type (S-3) appeared to develop normally in gross floral morphology, but the pollen grains were abnormal in shape and did not have germinating power. In an interspecific hybrid clone CS which belonged to S-1, fertility was restored in an open pollinated progeny. The use of CS and CSO-3 with its restored fertility, permitted the planning of breeding the chestnut hybrid cultivars propagated by seeds. The inbred clones with either male sterility or restorer genes are first bred mainly by back crossing with parents with favorable pollen. The clones are selected individually for early bearing, wasp and disease resistance, and restoration. Then, the hybrid seedling lines between male sterile and restorer inbreds are evaluated for homogenity in nut characters and tree habits. Next, the hybrid seedling lines selected will be examined for crop yield, vigor and cross compatibility. The superior seedling lines are finally selected, and the parental inbreds are grafted to be propagated for seed production orchards. (Kaihara, S.)

  14. Public funding of abortions and abortion counseling for poor women.

    Edwards, R B

    1997-01-01

    This essay seeks to reveal the weakness in arguments against public funding of abortions and abortion counseling in the US based on economic, ethico-religious, anti-racist, and logical-consistency objections and to show that public funding of abortion is strongly supported by appeals to basic human rights, to freedom of speech, to informed consent, to protection from great harm, to justice, and to equal protection under the law. The first part of the article presents the case against public funding with detailed considerations of the economic argument, the ethico/religious argument, the argument that such funding supports racist genocide or eugenic quality control, and arguments that a logical inconsistency exists between the principles used to justify the legalization of abortions and arguments for public funding. The second part of the article presents the case for public funding by discussing the spending of public funds on morally offensive programs, arguments for public funding of abortion counseling for the poor, and arguments for public funding of abortions for the poor. It is concluded that it is morally unacceptable and rationally unjustifiable to refuse to expend public funds for abortions for low income women, because after all most money for legal abortions for the poor comes from welfare payments made to women. If conservative forces want to insure that no public funds pay for abortions, they must stop all welfare payments to pregnant women.

  15. Crime, Teenage Abortion, and Unwantedness

    2015-01-01

    This article disaggregates Donohue and Levitt’s (DL’s) national panel-data models to the state level and shows that high concentrations of teenage abortions in a handful of states drive all of DL’s results in their 2001, 2004, and 2008 articles on crime and abortion. These findings agree with previous research showing teenage motherhood is a major maternal crime factor, whereas unwanted pregnancy is an insignificant factor. Teenage abortions accounted for more than 30% of U.S. abortions in the 1970s, but only 16% to 18% since 2001, which suggests DL’s panel-data models of crime/arrests and abortion were outdated when published. The results point to a broad range of future research involving teenage behavior. A specific means is proposed to reconcile DL with previous articles finding no relationship between crime and abortion. PMID:28943645

  17. Sterility induction in tsetse

    1982-01-01

    The first laboratory and field experiments on genetic control were with tsetse flies, and they made use of the sterility in crosses and hybrids between closely related species of the Glossina morsitans complex. Backcrosses indicate that there are two separate sterility mechanisms involved: (a) genetic incompatibility between a mother and the products of alien genes in the embryo or larva in the uterus; (b) inability of hybrid males to inseminate due to incompatibility of their X-chromosomes with an alien Y or autosomes. The two largest sterile male release programmes have been in Tanzania and Upper Volta, and have used irradiation at the pupal or adult stage, respectively, for the production of sterility. Male tsetse are remarkably resistant to radiosterilization and, with the doses required to induce dominant lethals in more than 95% of sperms, premature senescence and lethargic behaviour of the males tends to result. With G. morsitans irradiated at the puparial stage these effects can be alleviated by the use of a nitrogen atmosphere during irradiation. If the puparia are then transferred to air at 11/sup 0/C for transport to the release site, immediate emergence occurs on re-warming after arrival. This advantageous procedure was used for the releases in Tanzania. In addition to dominant lethals, irradiation also produces chromosome translocations which cause inherited partial sterility. A homozygous translocation line was selected but this example did not have sufficient fitness to be used in a mass rearing programme. Chemosterilants can be applied by pupal dipping, adult contact with deposits or in aerosols. Studies are now in progress on their use in association with odour-baited traps or pheromone-baited decoys as a means of sterilizing the wild population and thus avoiding the costly and difficult process of mass rearing tsetse.

  18. Abortion in a just society.

    Science.gov (United States)

    Hunt, M E

    1993-01-01

    A female Catholic theologian imagines a just society that does not judge women who decide to undergo an abortion. The Church, practitioners, and the courts must trust that women do make person-enhancing choices about the quality of life. In the last 15 years most progress in securing a woman's right to abortion has been limited to white, well-educated, and middle or upper middle class women. A just society would consider reproductive options a human right. Abortion providers are examples of a move to a just society; they are committed to women's well-being. There are some facts that make one pessimistic about achieving abortion in a just society. The US Supreme Court plans to review important decisions establishing abortion as a civil right. Further, some men insist on suing women who want to make their own reproductive decisions--an anti-choice tactic to wear away women's right to reproductive choice. Bombings of abortion clinics and harassment campaigns by anti-choice groups are common. These behaviors strain pro-choice proponents emotionally, psychically, and spiritually. Their tactics often lead to theologians practicing self-censorship because they fear backlash. Abortion providers also do this. Further, the reaction to AIDS is that sex is bad. Anti-abortion groups use AIDS to further their campaigns, claiming that AIDS is a punishment for sex. Strategies working towards abortion in a just society should be education and persuasion of policymakers and citizens about women's right to choose, since they are the ones most affected by abortion. Moreover, only women can secure their rights to abortion. In a just society, every health maintenance organization, insurance company, and group practice would consider abortion a normal service. A just society provides for the survival needs of the most marginalized.

    Informed consent mandates for abortion providers may infringe the First Amendment's freedom of speech. On the other hand, they may reinforce the physician's duty to obtain informed consent. Courts can promote both doctrines by ensuring that compelled physician speech pertains to medical facts about abortion rather than abortion ideology and that compelled speech is truthful and not misleading. © 2015 American Society of Law, Medicine & Ethics, Inc.

  20. Access to abortion: what women want from abortion services.

    Whether Canadian physicians can refuse to refer women for abortion and whether private clinics can charge for abortions are matters of controversy. We sought to identify barriers to access for women seeking therapeutic abortion and to have them identify what they considered to be most important about access to abortion services. Women presenting for abortion over a two-month period at two free-standing abortion clinics, one publicly funded and the other private, were invited to participate in the study. Phase I of the study involved administration of a questionnaire seeking information about demographics, perceived barriers to access to abortion, and what the women wanted from abortion services. Phase II involved semi-structured interviews of a convenience sample of women to record their responses to questions about access. Responses from Phase I questionnaires were compared between the two clinics, and qualitative analysis was performed on the interview responses. Of 423 eligible women, 402 completed questionnaires, and of 45 women approached, 39 completed interviews satisfactorily. Women received information about abortion services from their physicians (60.0%), the Internet (14.8%), a telephone directory (7.8%), friends or family (5.3%), or other sources (12.3%). Many had negative experiences in gaining access. The most important issue regarding access was the long wait time; the second most important issue was difficulty in making appointments. In the private clinic, 85% of the women said they were willing to pay for shorter wait times, compared with 43.5% in the public clinic. Physicians who failed to refer patients for abortion or provide information about obtaining an abortion caused distress and impeded access for a significant minority of women requesting an abortion. Management of abortion services should be prioritized to reflect what women want: particularly decreased wait times for abortion and greater ease and convenience in booking appointments

  1. Second trimester abortions in India.

    2008-05-01

    This article gives an overview of what is known about second trimester abortions in India, including the reasons why women seek abortions in the second trimester, the influence of abortion law and policy, surgical and medical methods used, both safe and unsafe, availability of services, requirements for second trimester service delivery, and barriers women experience in accessing second trimester services. Based on personal experiences and personal communications from other doctors since 1993, when I began working as an abortion provider, the practical realities of second trimester abortion and case histories of women seeking second trimester abortion are also described. Recommendations include expanding the cadre of service providers to non-allopathic clinicians and trained nurses, introducing second trimester medical abortion into the public health system, replacing ethacridine lactate with mifepristone-misoprostol, values clarification among providers to challenge stigma and poor treatment of women seeking second trimester abortion, and raising awareness that abortion is legal in the second trimester and is mostly not requested for reasons of sex selection.

  2. Psychiatric sequelae of induced abortion.

    1984-03-01

    An attempt is made to identify and document the problems of comparative evaluation of the more recent studies of psychiatric morbidity after abortion and to determine the current consensus so that when the results of the joint RCGP/RCOG study of the sequelae of induced abortion become available they can be viewed in a more informed context. The legalization of abortion has provided more opportunities for studies of subsequent morbidity. New laws have contributed to the changing attitudes of society, and the increasing acceptability of the operation has probably influenced the occurrence of psychiatric sequelae. The complexity of measuring psychiatric sequelae is evident from the many terms used to describe symptomatology and behavioral patterns and from the number of assessment techniques involved. Numerous techniques have been used to quantify psychiatric sequelae. Several authors conclude that few psychiatric problems follow an induced abortion, but many studies were deficient in methodology, material, or length of follow-up. A British study in 1975 reported a favorable outcome for a "representative sample" of 50 National Health Service patients: 68% of these patients had an absence of or only mild feelings of guilt, loss, or self reproach and considered abortion as the best solution to their problem. The 32% who had an adverse outcome reported moderate to severe feelings of guilt, regret, loss, and self reproach, and there was evidence of mental illness. In most of these cases the adverse outcome was related to the patient's environment since the abortion. A follow-up study of 126 women, which compared the overall reaction to therapeutic abortion between women with a history of previous mild psychiatric illness and those without reported that a significantly different emotional reaction could not be demonstrated between the 2 groups. In a survey among women seeking an abortion 271 who were referred for a psychiatric opinion regarding terminations of pregnancy

It is used to synchronize BPM processor Libera logging beam position data to identify beam abort source and improve the stability of accelerator. The concept design and engineering design of beam abort trigger module are introduced in this paper, and lab test results of this module using RF signal source also presented. Online beam test results show that this module has achieved design goal, could be used to log beam position data before beam abort. (authors)

  4. Psychosocial aspects of induced abortion.

    Stotland, N L

    1997-09-01

    US anti-abortion groups have used misinformation on the long-term psychological impact of induced abortion to advance their position. This article reviews the available research evidence on the definition, history, cultural context, and emotional and psychiatric sequelae of induced abortion. Notable has been a confusion of normative, transient reactions to unintended pregnancy and abortion (e.g., guilt, depression, anxiety) with serious mental disorders. Studies of the psychiatric aspects of abortion have been limited by methodological problems such as the impossibility of randomly assigning women to study and control groups, resistance to follow-up, and confounding variables. Among the factors that may impact on an unintended pregnancy and the decision to abort are ongoing or past psychiatric illness, poverty, social chaos, youth and immaturity, abandonment issues, ongoing domestic responsibilities, rape and incest, domestic violence, religion, and contraceptive failure. Among the risk factors for postabortion psychosocial difficulties are previous or concurrent psychiatric illness, coercion to abort, genetic or medical indications, lack of social supports, ambivalence, and increasing length of gestation. Overall, the literature indicates that serious psychiatric illness is at least 8 times more common among postpartum than among postabortion women. Abortion center staff should acknowledge that the termination of a pregnancy may be experienced as a loss even when it is a voluntary choice. Referrals should be offered to women who show great emotional distress, have had several previous abortions, or request psychiatric consultation.

    Updated clinical recommendations for medical induced abortion procedure. A systematic review of French and English literature, reviewing the evidence relating to the provision of medical induced abortion was carried out on PubMed, Cochrane Library and international scientific societies recommendations. The effectiveness of medical abortion is higher than 95% when the protocols are adjusted to gestational age (EL1). Misoprostol alone is less effective than a combination of mifepristone and misoprostol (EL1). Gemeprost is less effective than misoprostol (EL2). The dose of 200mg of mifepristone should be preferred to 600mg (NP1, Rank A). Mifepristone can be taken at home (professional agreement). The optimum interval between mifepristone and misoprostol intake should be 24 to 48 hours (EL1, grade A). Before 7 weeks LMP, the dose of 400μg misoprostol should be given orally (EL1, grade A) eventually repeated after 3hours if no bleeding occurs. For optimal effectiveness between 7 and 14 LMP, the interval between mifepristone and misoprostol should not be shortened to less than 8hours (grade 1). An interval of 24 to 48hours will not affect the effectiveness of the method provided misoprostol dosage is 800μg (EL1). Vaginal, sublingual or buccal routes of administration are more effective and better tolerated than the oral route, which should be abandoned (EL1). An amount of 800μg sublingual or buccal misoprostol route has the same effectiveness than the vaginal route but more gastrointestinal side effects (EL1, grade A). Between 7 and 9 LMP, it does not seem necessary to repeat misoprostol dose whereas it should be repeated beyond 9 SA (grade B). Between 9 and 14 LMP, the dose of 400μg misoprostol given either vaginally, buccally or sublingually should be repeated every 3hours if needed (with a maximum of 5 doses) (EL2, grade B). There is no strong evidence supporting routine antibiotic prophylaxis for medical abortion (professional agreement). Rare contraindications

    The fertility of M 1 plants, which developed from dried rice (c.v. Zhe9248) seeds treated with γ-rays at the dosage of 300 Gy, decreased dramatically, and some of the M 1 plants showed completely male sterile. There were still fertile and sterile plants in the M 2 F 1 population of artificially emasculated high sterile Zhe9248 M 1 plants crossed to normal variety G93-89, and consequently, Zhe9248 was back crossed to the sterile plants successively as recurrent parent. In all the above back cross populations, fertile and sterile plants segregated in a 1 : 1 ratio. The M 4 BC 2 male sterile plants were crossed to various rice materials, e.g. early season indica rice (Zhefu 504, H416), middle season indica rice (Chuan-si-ran-zhan, Yu-Zhan), maintainer lines (Fu-Nan B, 351 B) and restorer lines (IR36, 20964). In all the above F 1 populations, male sterile and fertile plants again segregated in a 1 : 1 ratio. In addition, sib-crossing were made in the back crosses and hybrid crosses between male sterile and fertile plants, male sterile and fertile plants appeared in a similar fashion as in test crosses. However, no male sterile plants were recovered from fertile plants either of back crosses or test crosses. The anthers of male sterile plants appeared small and poorly developed, the pollen showed typical abortion or round abortion, the seed set in bagged panicles was very low. The experimental data showed that this male sterile rice mutant was inherited in a single-gene mode

  7. Mental health consequences of abortion and refused abortion.

    Watter, W W

    1980-02-01

    There is no scientific evidence to support the hypothesis put forth by Dr. Philip Ney in a recent article published in the Canadian Journal of Psychiatry that induced abortion is associated with an increase in child abuse. There are, however, numerous studies which support the contention that mandatory motherhood adversely affects the mental health of both the mother and the offspring. Studies conducted in Sweden, Scotland, and Czechoslovakia revealed that women who were refused abortions frequently experienced serious psychosocial difficulties for long periods of time following abortion refusal. Case controlled follow-up studies, conducted in Sweden and Czechoslovakia, of offspring born to women who were refused abortions demonstrated that a higher proportion of the unwanted children required psychiatric services, engaged in criminal behavior, and did less well in school than the controlled children. These studies have implications for the current Canadian law which permits a woman to obtain an abortion if pregnancy continuation will endanger her health. In view of the above statistical evidence, and the fact that mortality and morbidity are known to be lower for abortion than for childbirth, any person who denies a woman the right to have an abortion is increasing the risk that the health of the woman will be endangered. By law, therefore, all abortion requests should be honored.

    We offer evidence that legalized abortion has contributed significantly to recent crime reductions. Crime began to fall roughly 18 years after abortion legalization. The 5 states that allowed abortion in 1970 experienced declines earlier than the rest of the nation, which legalized in 1973 with Roe v. Wade. States with high abortion rates in the 1970s and 1980s experienced greater crime reductions in the 1990s. In high abortion states, only arrests of those born after abortion legaliz...

    Koskinen, David Jason [Univ. College London, Bloomsbury (United Kingdom)

    2009-02-01

    The Main Injector Neutrino Oscillation Search (MINOS) is a long-baseline accelerator neutrino experiment designed to measure properties of neutrino oscillation. Using a high intensity muon neutrino beam, produced by the Neutrinos at Main Injector (NuMI) complex at Fermilab, MINOS makes two measurements of neutrino interactions. The first measurement is made using the Near Detector situated at Fermilab and the second is made using the Far Detector located in the Soudan Underground laboratory in northern Minnesota. The primary goal of MINOS is to verify, and measure the properties of, neutrino oscillation between the two detectors using the v μ→ Vτ transition. A complementary measurement can be made to search for the existence of sterile neutrinos; an oft theorized, but experimentally unvalidated particle. The following thesis will show the results of a sterile neutrino search using MINOS RunI and RunII data totaling ~2.5 x 1020 protons on target. Due to the theoretical nature of sterile neutrinos, complete formalism that covers transition probabilities for the three known active states with the addition of a sterile state is also presented.

    Nyong'o, D; Oodit, G

    1996-01-01

    Despite a contraceptive prevalence rate of 75% Mauritius has a high incidence of unsafe abortions because of unprotected intercourse experienced by many young women in a rapidly industrializing environment. The Mauritius Family Planning Association (MFPA) tackled the issue of unsafe abortion in 1993. Abortion is illegal in the country, and the Catholic Church also strongly opposes modern family planning methods, thus the use of withdrawal and/or calendar methods have been increasing. The MFPA organized an advocacy symposium in 1993 on unsafe abortion with the result of revealing the pressure the Church was exerting relative to abortion and contraceptives. The advocacy campaign of the MFPA consists of having abortion legalized on health grounds and improving family planning services, especially for young unmarried women and men. The full support of the media was secured on the abortion issue: articles appeared, meetings were attended by the press, and public relations support was also received from them. The MFPA worked closely with parliamentarians. A motion was tabled in 1994 in the National Assembly which called for legalization of abortion on health grounds, but the Church squelched its debate. In March 1994 MFPA hosted the IPPF African Regional Conference on Unsafe Abortion in Mauritius with the participation of over 100 representatives from 20 countries, and subsequently a second motion was tabled without parliamentary debate. The deliberations were covered by the media and the Ministry of Women's Rights recognized abortion as an urgent issue as outlined in a white paper prepared for the Fourth World Conference on Women held in Beijing in 1995. The campaign changed the policy climate favorably making the public more conscious of unsafe abortion. The Ministry of Health decided to collect more data and the newly elected government seems to be more open about this issue.

    To determine the frequency of induced abortion and identify the role of sociocultural factors contributing to termination of pregnancy and associated morbidity and mortality in hospital setting. Prospective observational study. The study was conducted in the Department of Obstetrics and Gynaecology, Jinnah Postgraduate Medical Centre, Karachi from January 1999 to June 2001. The patients who were admitted for induced abortion were interviewed in privacy. On condition of anonymity they were asked about the age, parity, family setup and relationships, with particular emphasis on sociocultural reasons and factors contributing to induction of abortion. Details of status of abortionist and methods used for termination of pregnancy, the resulting complications and their severity were recorded. Out of total admissions, 57(2.35%) gave history of induced abortion. All women belonged to low socioeconomic class and 59.6% of them were illiterate. Forty-three (75.5%) of these women had never practiced contraception. Twenty-four (42%) were grandmultiparae and did not want more children. In 29 women (50.9%) the decision for abortion had been supported by the husband. In 25 women (43.8%) abortion was carried out by Daiyan (traditional midwives). Serious complications like uterine perforation with or without bowel injury were encountered in 25 (43.8%) of these women. During the study period illegally induced abortion accounted for 6 (10.5%) maternal deaths. Prevalence of poverty, illiteracy, grand multiparity and non-practice of contraception are strong determinants of induced abortion.

    1979-08-01

    A federal appeals court has affirmed lower court rulings that substantial portions of the Illinois' 1975 Abortion Act and 1977 Abortion Parental Consent Act are unconstitutional. The 7th Court adopted an April 12, 1978 district court opinion that invalidated several sections of the Illinois 1975 abortion statute, including parental and spousal consent requirements and provisions requiring that a woman be informed of the "physical competency" of the fetus at the time the abortion was to be performed. The appeals court specifically addressed the statute's provision making a liveborn fetus resulting from an abortion a ward of the state, unless the abortion was performed to save the woman's life. Regarding the 1977 Parental Consent Act, the 7th Circuit reaffirmed its August 1978 ruling that it is unconstitutional to require an unmarried minor to have the consent of both parents or, if they refused consent, a circuit court judge before undergoing an abortion. The appeals court also agreed with the lower court's November 2nd ruling that the Act's requirement of a 48-hour delay between the time the minor gives her consent and the performance of an abortion violated the equal protection clause of the 14th amendment.

  1. Attitudes toward abortion in Zambia.

    Despite Zambia's relatively progressive abortion law, women continue to seek unsafe, illegal abortions. Four domains of abortion attitudes - support for legalization, immorality, rights, and access to services - were measured in 4 communities. A total of 668 people were interviewed. Associations among the 4 domains were inconsistent with expectations. The belief that abortion is immoral was widespread, but was not associated with lack of support for legalization. Instead, it was associated with belief that women need access to safe services. These findings suggest that increasing awareness about abortion law in Zambia may be important for encouraging more favorable attitudes.

    1987-01-01

    This article presents current estimates of the number, rate, and proportion of abortions for all countries which make such data available. 76% of the world's population lives in countries where induced abortion is legal at least for health reasons. Abortion is legal in almost all developed countries. Most developing countries have some laws against abortion, but it is permitted at least for health reasons in the countries of 67% of the developing world's population. The other 33%--over 1 billion persons--reside mainly in subSaharan Africa, Latin America, and the most orthodox Muslim countries. By the beginning of the 20th century, abortion had been made illegal in most of the world, with rules in Africa, Asia, and Latin America similar to those in Europe and North America. Abortion legislation began to change first in a few industrialized countries prior to World War II and in Japan in 1948. Socialist European countries made abortion legal in the first trimester in the 1950s, and most of the industrialized world followed suit in the 1960s and 1970s. The worldwide trend toward relaxed abortion restrictions continues today, with governments giving varying reasons for the changes. Nearly 33 million legal abortions are estimated to be performed annually in the world, with 14 million of them in China and 11 million in the USSR. The estimated total rises to 40-60 million when illegal abortions added. On a worldwide basis some 37-55 abortions are estimated to occur for each 1000 women aged 15-44 years. There are probably 24-32 abortions per 100 pregnancies. The USSR has the highest abortion rate among developed countries, 181/1000 women aged 15-44, followed by Rumania with 91/1000, many of them illegal. The large number of abortions in some countries is due to scarcity of modern contraception. Among developing countries, China apparently has the highest rate, 62/1000 women aged 15-44. Cuba's rate is 59/1000. It is very difficult to calculate abortion rates in countries

    Researchers have described the difficulties of doing abortion work, including the psychosocial costs to individual providers. Some have discussed the self-censorship in which providers engage in to protect themselves and the pro-choice movement. However, few have examined the costs of this self-censorship to public discourse and social movements in the US. Using qualitative data collected during abortion providers' discussions of their work, we explore the tensions between their narratives and pro-choice discourse, and examine the types of stories that are routinely silenced - narratives we name "dangertalk". Using these data, we theorize about the ways in which giving voice to these tensions might transform current abortion discourse by disrupting false dichotomies and better reflecting the complex realities of abortion. We present a conceptual model for dangertalk in abortion discourse, connecting it to functions of dangertalk in social movements more broadly. Copyright © 2017 Elsevier Ltd. All rights reserved.

    1973-01-01

    A study was carried out at the Adolescent Unit of The Montreal Children's Hospital from September 1970 to December 1972, the focus of which evolved from the pregnant teenager in general to the short- and long-term effects of her abortion. Answers to a questionnaire administered to 65 pregnant girls to determine the psychosocial characteristics of the pregnant teenager indicated that these girls are not socially or emotionally abnormal. A follow-up study of 50 girls who had an abortion determined that the girls do not change their life styles or become emotionally unstable up to one year post-abortion, although most have a mild, normal reaction to the crisis. During the study period the clinic services evolved from mainly prenatal care to mainly abortion counselling, and then to providing the abortion with less counselling, placing emphasis on those cases which require other than medical services.

    Twelve different Cytoplasmic Male-Sterile (CMS) lines were crossed with 18 rice varieties. From the hybrid with japonica rice Nongken 58, twelve homokaryotic-heteroplasmic male sterile lines were developed in B7F1 after successive back crossing and selection for stable male sterility and desirable agronomic traits such as flowering habit and high out crossing rate. The experimental results demonstrated that expression of the CMS factors were influenced by the corresponding nuclear genes. Three pollen abortion types, including the typical, the spherical and the stained abortion, were observed in the homokaryotic-heteroplasmic male sterile lines. Formation of the aborted pollen grains was influenced by the interaction among specific cytoplasmic and the corresponding nuclear genes. As the CMS carriers, these homokaryotic-heteroplasmic lines will have significant impact on the utilization of multiple types of CMS in hybrid rice breeding. What is more important is that these CMS lines are the invaluable materials for the investigation of the molecular mechanism of CMS formation in rice. (author)

    Sterility is common in hybrids between divergent populations, such as the indica and japonica subspecies of Asian cultivated rice (Oryza sativa). Although multiple loci for plant hybrid sterility have been identified, it remains unknown how alleles of the loci interact at the molecular level. Here we show that a locus for indica-japonica hybrid male sterility, Sa, comprises two adjacent genes, SaM and SaF, encoding a small ubiquitin-like modifier E3 ligase-like protein and an F-box protein, respectively. Most indica cultivars contain a haplotype SaM(+)SaF(+), whereas all japonica cultivars have SaM(-)SaF(-) that diverged by nucleotide variations in wild rice. Male semi-sterility in this heterozygous complex locus is caused by abortion of pollen carrying SaM(-). This allele-specific gamete elimination results from a selective interaction of SaF(+) with SaM(-), a truncated protein, but not with SaM(+) because of the presence of an inhibitory domain, although SaM(+) is required for this male sterility. Lack of any one of the three alleles in recombinant plants does not produce male sterility. We propose a two-gene/three-component interaction model for this hybrid male sterility system. The findings have implications for overcoming male sterility in inter-subspecific hybrid rice breeding.

    In intraspecific crosses between cultivated rice (Oryza sativa) subspecies indica and japonica, the hybrid male sterility gene S24 causes the selective abortion of male gametes carrying the japonica allele (S24-j) via an allelic interaction in the heterozygous hybrids. In this study, we first examined whether male sterility is due solely to the single locus S24. An analysis of near-isogenic lines (NIL-F(1)) showed different phenotypes for S24 in different genetic backgrounds. The S24 heterozygote with the japonica genetic background showed male semisterility, but no sterility was found in heterozygotes with the indica background. This result indicates that S24 is regulated epistatically. A QTL analysis of a BC(2)F(1) population revealed a novel sterility locus that interacts with S24 and is found on rice chromosome 2. The locus was named Epistatic Factor for S24 (EFS). Further genetic analyses revealed that S24 causes male sterility when in combination with the homozygous japonica EFS allele (efs-j). The results suggest that efs-j is a recessive sporophytic allele, while the indica allele (EFS-i) can dominantly counteract the pollen sterility caused by S24 heterozygosity. In summary, our results demonstrate that an additional epistatic locus is an essential element in the hybrid sterility caused by allelic interaction at a single locus in rice. This finding provides a significant contribution to our understanding of the complex molecular mechanisms underlying hybrid sterility and microsporogenesis.

  8. Abortion in Croatia and Slovenia.

    Science.gov (United States)

    1992-01-01

    In Slovenia abortion will continue to be available during the first 10 weeks of pregnancy as it has been since 1978. The Slovenian Constitutional Court passed this decision in December, 1991 calling the right to abortion a basic human right. T he ruling was a setback both for the government's conservative parties and the Catholic church. In Croatia, where the Catholic church is campaigning against abortion, the situation is quite different. Zagreb is full of stickers and posters with anti-abortion messages branding abortion murder and spreading inaccurate information in announcements. In 1990, there were 56,000 abortions. For every child that was born, one was aborted. The largest Croatian newspaper publicizes the Catholic view. They want pro-choice women of the volunteer group Tresnjevka to stop their struggle. The church and conservative women's groups press for inclusion of abortion in the Constitution. They are very powerful, and the fear is that might soon succeed in restricting or outlawing abortion. Tresnjevka is making efforts to organize a coordination and information center for women in Zagreb where there are 350,000 women and children refugees. Informative brochures are printed on natural healing methods in gynecology, as drugs are very scarce, and addresses for gynecological emergency care are also provided. Abortion has been legally available on demand during the 1st 10 weeks of pregnancy since 1978. Fore year Tresnjevka has worked for women, trying to raise funds from personal donations and from the government for their activities. Funds from foreign countries have never been received. At present many of the group's activities are on hold because of lack of funds, nevertheless the determination to continue fighting is alive.

    Although stigma has been identified as a potential risk factor for the well-being of women who have had abortions, little attention has been paid to the study of abortion-related stigma. A systematic search of the databases Medline, PsycArticles, PsycInfo, PubMed and Web of Science was conducted; the search terms were "(abortion OR pregnancy termination) AND stigma * ." Articles were eligible for inclusion if the main research question addressed experiences of individuals subjected to abortion stigma, public attitudes that stigmatize women who have had abortions or interventions aimed at managing abortion stigma. To provide a comprehensive overview of this issue, any study published by February 2015 was considered. The search was restricted to English- and German-language studies. Seven quantitative and seven qualitative studies were eligible for inclusion. All but two dated from 2009 or later; the earliest was from 1984. Studies were based mainly on U.S. samples; some included participants from Ghana, Great Britain, Mexico, Nigeria, Pakistan, Peru and Zambia. The majority of studies showed that women who have had abortions experience fear of social judgment, self-judgment and a need for secrecy. Secrecy was associated with increased psychological distress and social isolation. Some studies found stigmatizing attitudes in the public. Stigma appeared to be salient in abortion providers' lives. Evidence of interventions to reduce abortion stigma was scarce. Most studies had limitations regarding generalizability and validity. More research, using validated measures, is needed to enhance understanding of abortion stigma and thereby reduce its impact on affected individuals. Copyright © 2016 by the Guttmacher Institute.

  10. Teenage pregnancies and abortion.

    Morgenthau, J E

    1984-01-01

    The issue of abortion, except when it is rendered moot because the fetus endangers the life of the mother, is not really a medical issue. The physician's role is to help patients achieve and maintain their maximum potential for physical, mental, and social well-being. To accomplish this, the physician must acquire a constantly evolving database of scientific knowledge, must evaluate this information in a critical and ethical manner, and must be prepared to apply what is learned. In the realm of applied ethics, no particular religion, profession, culture, class, or sex should be thought of as having all the answers in the realm of applied ethics. This physician's actions are predicated on the belief that, to a large extent, ethical precepts reflect the broader social and economic issues of the period in which they are articulated. If this is the case, then in today's world the population explosion, the postindustrial society, the women's rights movement, inequality of access, and the ability to perform prenatal diagnosis are all factors which have molded the approach to the issue of abortion. Only the last 3 of these can in any way be considered as medical. When considering the role of a physician in dealing with the issue of abortion in the adolescent, this individual relies on the concept articulated by the World Health Association (WHA): promoting the physical, emotional, and social well-being of one's patients. Each year in the US over 1 million 15-19 year olds become pregnant, resulting in over 600,000 births. Most of these pregnancies are unintentional, yet approximately 90% of the infants are kept in the home by mothers who are ill prepared to be parents. What is most disturbing is that the pregnancy rate for the younger mother, 16 years or under, is accounting for an ever increasing percentage of the total. Studies at the Adolescent Health Center of the Mount Sinai Hospital in New York City as well as national studies suggest that the younger teens are more

  11. Youth often risk unsafe abortions.

    1993-10-01

    The topic of this article is the use of unsafe abortion for unwanted pregnancies among adolescents. The significance of unsafe abortion is identified as a high risk of serious health problems, such as infection, hemorrhage, infertility, and mortality, and as a strain on emergency room services. The World Health Organization estimates that at least 33% of all women seeking hospital care for abortion complications are aged under 20 years. 50 million abortions are estimated to be induced annually, of which 33% are illegal and almost 50% are performed outside the health care system. Complications are identified as occurring due to the procedure itself (perforation of the uterus, cervical lacerations, or hemorrhage) and due to incomplete abortion or introduction of bacteria into the uterus. Long-term complications include an increased risk of ectopic pregnancy, chronic pelvic infection, and infertility. Mortality from unsafe abortion is estimated at 1000/100,000 procedures. Safe abortion mortality is estimated at 0.6/100,000. When infertility results, some cultures ascribe an outcast status or marriages are prevented or prostitution is assured. The risk of complications is considered higher for adolescents. Adolescents tend to delay seeking an abortion, lack knowledge on where to go for a safe procedure, and delay seeking help for complications. Peer advice may be limited or inadequate knowledge. Five studies are cited that illustrate the impact of unsafe abortion on individuals and health care systems. Abortions may be desired due to fear of parental disapproval of the pregnancy, abandonment by the father, financial and emotional responsibilities of child rearing, expulsion from school, or inability to marry if the child is out of wedlock. Medical, legal, and social barriers may prevent women and girls from obtaining safe abortion. Parental permission is sometimes a requirement for safe abortion. Fears of judgmental or callous health personnel may be barriers to

    Despite the universal recognition of unsafe abortion as a major public health problem, very little research has been conducted to document its precipitating factors in Burkina Faso. Our aim was to investigate the key determinants of induced abortion in a sample of women who sought postabortion care. A cross-sectional household survey was carried out from February to September 2012 in Ouagadougou, Burkina Faso. Data of 37 women who had had an induced abortion and 267 women who had had a spontaneous abortion were prospectively collected on sociodemographic characteristics, pregnancy and birth history, abortion experience, including previous abortion experience, and selected clinical information, including the type of abortion. A two-step regression analysis consisting of a univariate and a multivariate logistic regression was run on Stata version 11.2 in order to identify the key determinants of induced abortion. The findings indicated that 12% of all abortions were certainly induced. Three key factors were significantly and positively associated with the probability of having an induced abortion: whether the woman reported that her pregnancy was unwanted (odds ratio [OR] 10.45, 95% confidence interval [CI] 3.59-30.41); whether the woman reported was living in a household headed by her parents (OR 6.83, 95% CI 2.42-19.24); and if the woman reported was divorced or widowed (OR 3.47, 95% CI 1.08-11.10). On the contrary, being married was protective against induced abortion, with women who reported being married having an 83% (OR 0.17, CI 0.03-0.89) lower chance of having an induced abortion, even when the pregnancy was unwanted. This study has identified three major determinants of induced abortion in Ouagadougou, Burkina Faso. Improved targeted programs on family planning counseling, methods of contraception, and availability of contraceptives should be widely promoted.

    This study aimed to assess the association between perceived social support and induced abortion among young women in Lima, Peru. In addition, prevalence and incidence of induced abortion was estimated. A cross-sectional study enrolling women aged 18-25 years from maternal health centers in Southern Lima, Peru, was conducted. Induced abortion was defined as the difference between the total number of pregnancies ended in abortion and the number of spontaneous abortions; whereas perceived social support was assessed using the DUKE-UNC scale. Prevalence and incidence of induced abortion (per 100 person-years risk) was estimated, and the association of interest was evaluated using Poisson regression models with robust variance. A total of 298 women were enrolled, mean age 21.7 (± 2.2) years. Low levels of social support were found in 43.6% (95%CI 38.0%-49.3%), and 17.4% (95%CI: 13.1%- 21.8%) women reported at least one induced abortion. The incidence of induced abortion was 2.37 (95%CI: 1.81-3.11) per 100 person-years risk. The multivariable model showed evidence of the association between low perceived social support and induced abortion (RR = 1.94; 95%CI: 1.14-3.30) after controlling for confounders. There was evidence of an association between low perceived social support and induced abortion among women aged 18 to 25 years. Incidence of induced abortion was similar or even greater than rates of countries where abortion is legal. Strategies to increase social support and reduce induced abortion rates are needed.

  14. Genetically conditioned male sterility

    International Nuclear Information System (INIS)

    Gottschalk, W.

    1976-01-01

    A survey is given of two different types of genetically controlled male sterility in higher plants. 'Functional' male sterility is due to the action of mutated genes causing a misdifferentiation of the growing points in different specific ways. Under the influence of the genes of this group either the stamens or the archespore tissues are not differentiated. In other mutants functionable male germ cells are produced but cannot be used for fertilizing the egg cells because the anthers remain closed or anthers and stigma become spatially separated from each other. Other genes of the group are responsible for the transformation of stamens into carpels, i.e. for a change of the hermaphrodite flower into a unisexually female one. A second type of male sterility is due to the action of ms genes influencing the course of micro-sporogenesis directly. They cause the breakdown of this process in a specific meiotic stage characteristic for each gene of the group. This breakdown is introduced by the degeneration of PMCs, microspores, or pollen grains preventing the production of male germ cells. The female sex organs remain uninfluenced. (author)

    The use of polymeric medical devices has stimulated the development of new sterilization methods. The traditional techniques rely on ethylene oxide, but there are many questions concerning the carcinogenic properties of the ethylene oxide residues adsorbed on the materials after processing. Another common technique is the gamma irradiation process, but it is costly, its safe operation requires an isolated site and it also affects the bulk properties of the polymers. The use of a gas plasma is an elegant alternative sterilization technique. The plasma promotes an efficient inactivation of the micro-organisms, minimises the damage to the materials and presents very little danger for personnel and the environment. Pure oxygen reactive ion etching type of plasmas were applied to inactivate a biologic indicator, the Bacillus stearothermophilus, to confirm the efficiency of this process. The sterilization processes took a short time, in a few minutes the mortality was complete. In situ analysis of the micro-organisms' inactivating time was possible using emission spectrophotometry.

    1982-02-01

    In order to gain insight into the characteristics of sterilized women evaluating at the same time the effects of sterilization, 70 patients who underwent sterilization in an Obstetrics Unit were studied. The clinical records were analyzed and a questionnaire comprising general knowledge, attitudes, and conduct was applied. Women over 30 and with a parity of 4 or more predominated. There was a low frequency of abortions reported but this information is not reliable. The educational level was lower than the average for the Metropolitan Region and pointed to a more precocious initiation in sexual relationships than was found in a previous similar study. Religion proved to be no obstacle for sterilization nor was attendance to church subsequently diminished. A negative moral feeling towards the operation nearly disappeared following surgery. The fear of sexual dissatisfaction in husbands decreased following surgery and a similar effect was seen with regard to negative self-image. There were no changes in marital relations nor in their satisfaction. (author's modified)

  18. Why do women have abortions?

    Torres, A; Forrest, J D

    1988-01-01

    Most respondents to a survey of abortion patients in 1987 said that more than one factor had contributed to their decision to have an abortion; the mean number of reasons was nearly four. Three-quarters said that having a baby would interfere with work, school or other responsibilities, about two-thirds said they could not afford to have a child and half said they did not want to be a single parent or had relationship problems. A multivariate analysis showed young teenagers to be 32 percent more likely than women 18 or over to say they were not mature enough to raise a child and 19 percent more likely to say their parents wanted them to have an abortion. Unmarried women were 17 percent more likely than currently married women to choose abortion to prevent others from knowing they had had sex or became pregnant. Of women who had an abortion at 16 or more weeks' gestation, 71 percent attributed their delay to not having realized they were pregnant or not having known soon enough the actual gestation of their pregnancy. Almost half were delayed because of trouble in arranging the abortion, usually because they needed time to raise money. One-third did not have an abortion earlier because they were afraid to tell their partner or parents that they were pregnant. A multivariate analysis revealed that respondents under age 18 were 39 percent more likely than older women to have delayed because they were afraid to tell their parents or partner.

    Although abortion has been legal under broad criteria in Nepal since 2002, a significant proportion of women continue to obtain illegal, unsafe abortions, and no national estimates exist of the incidence of safe and unsafe abortions. Data were collected in 2014 from a nationally representative sample of 386 facilities that provide legal abortions or postabortion care and a survey of 134 health professionals knowledgeable about abortion service provision. Facility caseloads and indirect estimation techniques were used to calculate the national and regional incidence of legal and illegal abortion. National and regional levels of abortion complications and unintended pregnancy were also estimated. In 2014, women in Nepal had 323,100 abortions, of which 137,000 were legal, and 63,200 women were treated for abortion complications. The abortion rate was 42 per 1,000 women aged 15-49, and the abortion ratio was 56 per 100 live births. The abortion rate in the Central region (59 per 1,000) was substantially higher than the national average. Overall, 50% of pregnancies were unintended, and the unintended pregnancy rate was 68 per 1,000 women of reproductive age. Despite legalization of abortion and expansion of services in Nepal, unsafe abortion is still common and exacts a heavy toll on women. Programs and policies to reduce rates of unintended pregnancy and unsafe abortion, increase access to high-quality contraceptive care and expand safe abortion services are warranted.

  1. New German abortion law agreed.

    1995-07-15

    The German Bundestag has passed a compromise abortion law that makes an abortion performed within the first three months of pregnancy an unlawful but unpunishable act if the woman has sought independent counseling first. Article 218 of the German penal code, which was established in 1871 under Otto von Bismarck, had allowed abortions for certain medical or ethical reasons. After the end of the first world war, the Social Democrats tried to legalize all abortions performed in the first three months of pregnancy, but failed. In 1974, abortion on demand during the first 12 weeks was declared legal and unpunishable under the social liberal coalition government of chancellor Willy Brandt; however, the same year, the German Federal Constitution Court in Karlsruhe ruled the bill was incompatible with article 2 of the constitution, which guarantees the right to life and freedom from bodily harm to everyone, including the unborn. The highest German court also ruled that a pregnant woman had to seek a second opinion from an independent doctor before undergoing an abortion. A new, extended article 218, which included a clause giving social indications, was passed by the Bundestag. When Germany was unified, East Germans agreed to be governed by all West German laws, except article 218. The Bundestag was given 2 years to revise the article; however, in 1993, the Federal Constitution Court rejected a version legalizing abortion in the first 3 months of the pregnancy if the woman sought counsel from an independent physician, and suggested the recent compromise passed by the Bundestag, the lower house of the German parliament. The upper house, the Bundesrat, where the Social Democrats are in the majority, still has to pass it. Under the bill passed by the Bundestag, national health insurance will pay for an abortion if the monthly income of the woman seeking the abortion falls under a certain limit.

  2. Abortion: Defending Life

    Full Text Available This essay will analyze some of the debates around abortion in the National Congress due to the Constitutional Amendment Bill – PEC25/95, by Deputy Severino Cavalcanti (PPB/PE, where the main issue was precisely life defense. The discursive blocks that present the debate in relation to pregnancy interruption, the religious principles or biological determinism on which those debates are based, and the ways in which such discourses are maintained will be identified. Distinct understandings of life, as a result of the points used in such discourses, which are aligned with the position of the Catholic Church and the Feminist Movement - the social actors of this debate- are also discussed here.

  3. Psychological sequelae of induced abortion.

    1989-12-01

    This article reviews the scientific literature on the psychological sequelae of induced abortion. The methodology and results of studies carried out over the last twenty-two years are examined critically. The unanimous consensus is that abortion does not cause deleterious psychological effects. Women most likely to show subsequent problems are those who were pressured into the operation against their own wishes, either by relatives or because their pregnancy had medical or foetal contraindications. Legislation which restricts abortion causes problems for women with unwanted pregnancies and their doctors. It is also unjust, as it adversely most affects lower socio-economic class women.

    To determine whether or not a previous abortion has a deleterious effect on the outcome of a subsequent pregnancy, 6443 delivery records at Ramathibodi hospital between January and December 1982 were reviewed. The 2 study groups consisted of 143 women who had previously had an induced abortion and 315 women who had previously had a spontaneous abortion. Control groups were women having a 2nd child after a normal 1st pregnancy. The 1st study group had fewer women under 19 and over 35 and a lower educational level. Group 2 had more women with a pregnancy interval of less than 2 years. There was no difference between the study groups and the controls in premature rupture of fetal membranes, placenta previa, cesarean sections, manual removal of placenta, retained secundine, postpartum hemorrhage, low birth weight, Apgar score less than 6, congenital abnormalities, or perinatal mortality. The only difference between both study groups and the controls was that there was a higher percentage of assisted deliveries in both study groups. This finding is probably the result of the fact that these were 1st births and is totally unrelated to previous abortion.

    Biochemical research of biological systems is highly developed, and it has disclosed a spectrum of chemical reactions, genetic processes, and the pathological development of various diseases. The fundamental hypothesis of physical processes in biological systems, in particular of coherent electrically polar vibrations and electromagnetic activity, was formulated by H. Fröhlich; he assumed connection of cancer process with degradation of coherent electromagnetic activity. But the questions of cellular structures capable of the coherent electrical polar oscillation, mechanisms of energy supply, and the specific role of the endogenous electromagnetic fields in transport, organisation, interactions, and information transfer remained open. The nature of physical disturbances caused by some diseases (including the recurrent abortion in humans and the cancer) was unknown. We have studied the reasons of recurrent abortions in humans by means of the cell mediated immunity (using immunologic active RNA prepared from blood of inbred laboratory mice strain C3H/H2K, infected with the lactate dehydrogenase elevating virus-LD V) and the cytogenetic examination from karyotype pictures. The recurrent abortion group contained women with dg. spontaneous abortion (n = 24) and the control group was composed of 30 healthy pregnant women. Our hypothesis was related to quality of endometrium in relation to nidation of the blastocyst. The energetic insufficiency (ATP) inhibits normal development of fetus and placenta. We hope that these ideas might have impact on further research, which could provide background for effective interdisciplinary cooperation of malignant and non-malignant diseases.

    Bhatti, Khadijah Z; Nguyen, Antoinette T; Stuart, Gretchen S

    2018-03-01

    Medical abortion is a safe, effective, and acceptable option for patients seeking an early nonsurgical abortion. In 2014, medical abortion accounted for nearly one third (31%) of all abortions performed in the United States. State-level attempts to restrict reproductive and sexual health have recently included bills that require physicians to inform women that a medical abortion is reversible. In this commentary, we will review the history, current evidence-based regimen, and regulation of medical abortion. We will then examine current proposed and existing abortion reversal legislation. The objective of this commentary is to ensure physicians are armed with rigorous evidence to inform patients, communities, and policy makers about the safety of medical abortion. Furthermore, given the current paucity of evidence for medical abortion reversal, physicians and policy makers can dispel bad science and misinformation and advocate against medical abortion reversal legislation.

    To determine whether induced abortion (IA) increases breast cancer (BC) risk. A population-based case-control study was performed from Dec, 2000 to November, 2004 in Shanghai, China, where IA could be verified through the family planning network and client medical records. Structured questionnaires were completed by 1,517 cases with primary invasive epithelial breast cancer and 1,573 controls frequency- matched to cases for age group. The information was supplemented and verified by the family planning records. Statistical analysis was conducted with SAS 9.0. After adjusting for potential confounders, induced abortions were not found to be associated with breast cancer with OR=0.94 (95%CI= 0.79-1.11). Compared to parous women without induced abortion, parous women with 3 or more times induced abortion (OR=0.66, 95%CI=0.46 to 0.95) and women with 3 or more times induced abortion after the first live birth (OR=0.66, 95%CI =0.45 to 0.97) showed a lower risk of breast cancer, after adjustment for age, level of education, annual income per capita, age at menarche, menopause, parity times, spontaneous abortion, age at first live birth, breast-feeding, oral contraceptives, hormones drug, breast disease, BMI, drinking alcohol, drinking tea, taking vitamin/calcium tablet, physical activity, vocation, history of breast cancer, eating the bean. The results suggest that a history of induced abortions may not increase the risk of breast cancer.

    Full Text Available Objective: to analyze women's perception in relation to their partner's reaction and behavior during the abortion process in two Brazilian capitals, associating the variables from women who suffered a spontaneous abortion with those from women who induced it. Methods: semi-structured, questionnaire-based interviews were conducted with 285 women who underwent spontaneous abortion and 31 who reported having induced it. The data were analyzed using the thematic analysis technique, and, subsequently, by the IBM SPSS Statistics Standard Edition software program. The significance level was set at p < 0.05. Results: in both capitals, the women who induced an abortion referred to the partner as the person who could not find out about the abortion (p<0.01 in Natal; p = 0.02 in São Paulo-SP and, simultaneously, as the one who could have avoided it (p < 0.01 in Natal; p = 0.03 in São Paulo. In Natal-RN, induced abortion was associated with the partner's absence at the time pregnancy was confirmed (p = 0.02 and, in Sao Paulo-SP, with their negative reaction to news of the pregnancy (p = 0.04 and lack of participation in the abortion process (p < 0.01. Conclusion: despite having achieved independence, women still regard male participation in the abortion process as an important factor. The specifics of each capital denote the influence of the geographic and cultural dimension, indicating the need to take into account the particulars of each region in Brazil while considering a holistic approach to women's health.

    The standards for quality management systems recognize that, for certain processes used in manufacturing, the effectiveness of the process cannot be fully verified by subsequent inspection and testing of the product. Sterilization is an example of such a process. For this reason, sterilization processes are validated for use, the performance of sterilization process is monitored routinely and the equipment is maintained according to ISO 13 485. Different aspects of this norm are presented

  12. Sterilizing insects with ionizing radiation

    International Nuclear Information System (INIS)

    Bakri, A.; Mehta, K.; Lance, D.R.

    2005-01-01

    Exposure to ionizing radiation is currently the method of choice for rendering insects reproductively sterile for area-wide integrated pest management (AW-IPM) programmes that integrate the sterile insect technique (SIT). Gamma radiation from isotopic sources (cobalt-60 or caesium-137) is most often used, but high-energy electrons and X-rays are other practical options. Insect irradiation is safe and reliable when established safety and quality-assurance guidelines are followed. The key processing parameter is absorbed dose, which must be tightly controlled to ensure that treated insects are sufficiently sterile in their reproductive cells and yet able to compete for mates with wild insects. To that end, accurate dosimetry (measurement of absorbed dose) is critical. Irradiation data generated since the 1950s, covering over 300 arthropod species, indicate that the dose needed for sterilization of arthropods varies from less than 5 Gy for blaberid cockroaches to 300 Gy or more for some arctiid and pyralid moths. Factors such as oxygen level, and insect age and stage during irradiation, and many others, influence both the absorbed dose required for sterilization and the viability of irradiated insects. Consideration of these factors in the design of irradiation protocols can help to find a balance between the sterility and competitiveness of insects produced for programmes that release sterile insects. Many programmes apply 'precautionary' radiation doses to increase the security margin of sterilization, but this overdosing often lowers competitiveness to the point where the overall induced sterility in the wild population is reduced significantly.

  13. Induced pollen sterility in petunia. Mode of inheritance and tapetal behavior

    1975-01-01

    A study was undertaken to investigate the characteristics of different mutants for induced pollen sterility in Petunia hybrida Hort. The F 1 hybrid zygotes (TL-h 1 #female# x Sf-la #male#) were exposed to a 0.2% solution of ethyl methane sulfonate and to 0.75kR of 60 Co gamma rays. Their seeds were sown and pollen sterile plants were observed in the M 1 . The pattern of inheritance in the F 2 and the backcrosses of some selected pollen sterile M 1 mutants showed that sterility mutations had been induced. Whether the mutations are recessive or dominant is not yet known, but it has been shown that they act through the sporophytic tissues. Morphological and cytological observations on four highly sterile M 1 plants showed a similar abnormal behavior of the tapetum. The tapetum of the pollen sterile anthers was thicker, more vacuolated and did persist until a later stage than those in fertile anthers. It is suggested that the persistence of the tapetum after a certain stage blocks the trophic process required for the development of the microspore into viable pollen, and the cause of pollen abortion is sporophytic even when no inheritance of the sterility is observed [fr

    A male sterile mutant was obtained after injection of exogenous λ DNA into wheat line 814527. Meiosis of pollen mother cells (PMC) of the mutant and its receptor (line 814527) were observed. The results showed that the frequency of chromosomal variation of the sterile line was 18%, and that of the receptor was 0.8%. The main types of variation included univalent, chromosome lagging, chromosome fragment, chromosome bridge, micronucleus, abnormal ditrad and tetrad. The fragment of DNA injected into the receptor may influence the normal genetic process of chromosomes in pollen mother cells, and this may cause variations of chromosomes. The chromosome variation in meiosis may cause a part of pollen mother cells to abort, but it is not the main cause of abortion

  15. Psychiatric aspects of induced abortion.

    2011-08-01

    Approximately one third of the women in the United States have an abortion during their lives. In the year 2008, 1.21 million abortions were performed in the United States (Jones and Koolstra, Perspect Sex Reprod Health 43:41-50, 2011). The psychiatric outcomes of abortion are scientifically well established (Adler et al., Science 248:41-43, 1990). Despite assertions to the contrary, there is no evidence that abortion causes psychiatric problems (Dagg, Am J Psychiatry 148:578-585, 1991). Those studies that report psychiatric sequelae suffer from severe methodological defects (Lagakos, N Engl J Med 354:1667-1669, 2006). Methodologically sound studies have demonstrated that there is a very low incidence of frank psychiatric illness after an abortion; women experience a wide variety of feelings over time, including, for some, transient sadness and grieving. However, the circumstances that lead a woman to terminate a pregnancy, including previous and/or ongoing psychiatric illness, are independently stressful and increase the likelihood of psychiatric illness over the already high baseline incidence and prevalence of mood and anxiety disorders among women of childbearing age. For optimal psychological outcomes, women, including adolescents, need to make autonomous and supported decisions about problem pregnancies. Clinicians can help patients facing these decisions and those who are working through feelings about having had abortions in the past.

    2014-08-01

    Across four decades of political and social action, Nepal changed from a country strongly enforcing oppressive abortion restrictions, causing many poor women's long imprisonment and high rates of abortion-related maternal mortality, into a modern democracy with a liberal abortion law. The medical and public health communities supported women's rights activists in invoking legal principles of equality and non-discrimination as a basis for change. Legislative reform of the criminal ban in 2002 and the adoption of an Interim Constitution recognizing women's reproductive rights as fundamental rights in 2007 inspired the Supreme Court in 2009 to rule that denial of women's access to abortion services because of poverty violated their constitutional rights. The government must now provide services under criteria for access without charge, and services must be decentralized to promote equitable access. A strong legal foundation now exists for progress in social justice to broaden abortion access and reduce abortion stigma. Copyright © 2014 International Federation of Gynecology and Obstetrics.

    2014-03-01

    Misinformation about the risks and sequelae of abortion is widespread. The purpose of this study was to examine whether women having an abortion who believe that there should be restrictions to abortion (i.e., that some other women should not be allowed to have an abortion) also believe this misinformation about the health risks associated with abortion. We carried out a cross-sectional survey of women presenting consecutively for an abortion at an urban abortion clinic in Vancouver, British Columbia, between February and September 2012. Of 1008 women presenting for abortion, 978 completed questionnaires (97% response rate), and 333 of these (34%) favoured abortion restrictions. More women who favoured restrictions believed that the health risk of an abortion was the same as or greater than the health risk of childbirth (84.2% vs. 65.6%, P abortion caused mental health problems (39.1% vs. 28.3%, P abortion caused infertility (41.7% vs. 21.9%, P abortion should not be restricted was found to be a significantly correlated with correct answers about health risks, mental health problems, and infertility. Misinformed beliefs about the risks of abortion are common among women having an abortion. Women presenting for abortion who favoured restrictions to abortion have more misperceptions about abortion risks than women who favour no restrictions.

  18. Laparoscopic female sterilization.

    Filshie, G M

    1989-09-01

    An overview of laparoscopic sterilization techniques from a historical and practical viewpoint includes instrumentation, operative techniques, mechanical occlusive devices, anesthesia, failure rates, morbidity and mortality. Laparoscope was first reported in 1893, but was developed simultaneously in France, Great Britain, Canada and the US in the 1960s. There are smaller laparoscopes for double-puncture procedures, and larger, single-puncture laparoscopes. To use a ring or clip, a much larger operating channel, up to 8 mm is needed. Insufflating gas may be CO2, which does not support combustion, but is more uncomfortable, NO2, which is also an anesthetic, and room air often used in developing countries. Unipolar electrocautery is now rarely used, in fact most third party payers do not allow it. Bipolar cautery, thermal coagulation and laser photocoagulation are safer methods. Falope rings, Hulka-Clemens, Filshie, Bleier, Weck and Tupla clips are described and illustrated. General anesthesia, usually a short acting agent with a muscle relaxant, causes 33% of the mortality of laparoscope, often due to cardiac arrest and arrhythmias, preventable with atropine. Local anesthesia is safer and cheaper and often used in developing countries. Failure rates of the various laparoscopic tubal sterilization methods are reviewed: most result from fistula formation. Mortality and morbidity can be caused by bowel damage, injury or infection, pre- existing pelvic infection, hemorrhage, gas embolism (avoidable by the saline drip test), and other rare events.

  19. Virtue theory and abortion.

    Hursthouse, Rosalind

    1991-01-01

    The sort of ethical theory derived from Aristotle, variously described as virtue ethics, virtue-based ethics, or neo-Aristotelianism, is becoming better known, and is now quite widely recognized as at least a possible rival to deontological and utilitarian theories. With recognition has come criticism, of varying quality. In this article I shall discuss nine separate criticisms that I have frequently encountered, most of which seem to me to betray an inadequate grasp either of the structure of virtue theory or of what would be involved in thinking about a real moral issue in its terms. In the first half I aim particularly to secure an understanding that will reveal that many of these criticisms are simply misplaced, and to articulate what I take to be the major criticism of virtue theory. I reject this criticism, but do not claim that it is necessarily misplaced. In the second half I aim to deepen that understanding and highlight the issues raised by the criticisms by illustrating what the theory looks like when it is applied to a particular issue, in this case, abortion.

  20. Abortion - a philosophical perspective

    Directory of Open Access Journals (Sweden)

    MN Jali

    2001-09-01

    Full Text Available The central issue in the abortion debate is the moral status of the conceptus. There are two positions that argue this issue. At one extreme are the views of the pro-life group which argues that human life begins at the moment of conception whilst at the other are views of the pro-choice group that argues in favour of a woman’s right to self-determination. Two basic principles come into conflict in this debate, namely the Value of Life and that of Self-determination. In this paper the arguments forwarded by each group in justification of its position are presented. Also discussed is the moderate developmental viewpoint which accepts that the genetic basis of an individual is established at conception. Some development, however, has to occur before the conceptus can be called a person. The fact that an entity is a potential person is a prima facie reason for not destroying it. On the other hand, we need not conclude that a person has a right to life by virtue of that potentiality. Simultaneously we should recognise that the right a potential entity has, may be nullified by the woman’s right to self-determination.

A significant number of induced abortions (22.2% were incidentally caused by inappropriate use of contraceptives by providers. Sexual activities start as early as 9 years in Katete. Most youths with induced abortions were involved in unstable relationships, desired to continue with education, feared to ruin their future, and had limited knowledge and inconsistent use of contraceptive methods. The major determinants for induced abortions amongst participants were unplanned/unintended pregnancies. Other determinants such as illiteracy, lack of information, young age, poverty, and unsafe sex need to be addressed. There is need to promote consistent and correct use of contraceptives, to strengthen the health care delivery system and maintain the cold chain of contraceptive supply for sustainable availability and accessibility. Conjugated efforts by health care providers, community leaders, policy makers and politicians are needed to extirpate negative believes (on modern contraceptives and cultural norms that promote unhealthy sexual and reproductive life.

  2. Late Abortion: A Comprehensive Review

    Full Text Available Late termination of pregnancy (LTOP is defined as an abortion carried out beyond 24 gestational weeks, when the fetus has arguably attained viability. In Taiwan, the current abortion law, bearing a eugenic title, allows LTOP on certain medical grounds. However, the fetal and maternal conditions that constitute medical grounds are not clarified and remain legally untested. Professional debate on the abortion issue is also lacking in academia in Taiwan, despite societal concerns. With the advent of technology to detect fetal abnormalities, obstetricians are now confronted more frequently with acute dilemmas regarding LTOP. Quite often, they sail in an uncharted sea with no clinical guidelines from their professional societies or affiliated hospitals. Recently, LTOP at 35 gestational weeks for a fetus with Down syndrome, complicated with polyhydramnios and tetralogy of Fallot, triggered media scrutiny and aroused much public attention. Although the clinical decision making for pregnancies with fetal abnormalities entails increasingly balanced information and consideration in terms of the medical, ethical, legal, psychologic, and societal aspects, society at large is unaware of the complexity and intertwined nature of various abortion issues, especially LTOP. Obstetricians are now in a vulnerable position in Taiwanese society, where litigations relevant to the practice of early abortions are not rare. Therefore, a global and in-depth look into abortion issues from legal and ethical dimensions is indispensable for modern obstetric practice. This review considers the core issues in LTOP, including what conditions constitute a “serious” fetal abnormality to justify LTOP, the incidence of LTOP, legislation regarding LTOP in Western countries, and recent research on ambivalent fetal pain. It will also present procedures, some under the auspices of the ethical committee of a Presbyterian hospital in Taiwan, for clinical decision making, particularly

    Sterile neutrinos produced through oscillations are a well motivated dark matter candidate, but recent constraints from observations have ruled out most of the parameter space. We analyze the impact of new interactions on the evolution of keV sterile neutrino dark matter in the early Universe. Based on general considerations we find a mechanism which thermalizes the sterile neutrinos after an initial production by oscillations. The thermalization of sterile neutrinos is accompanied by dark entropy production which increases the yield of dark matter and leads to a lower characteristic momentum. This resolves the growing tensions with structure formation and x-ray observations and even revives simple nonresonant production as a viable way to produce sterile neutrino dark matter. We investigate the parameters required for the realization of the thermalization mechanism in a representative model and find that a simple estimate based on energy and entropy conservation describes the mechanism well.

  6. Sterile Endophthalmitis after Intravitreal Injections

    Joaquín Marticorena

    2012-01-01

    Full Text Available Sterile endophthalmitis appears as an infrequent complication of intravitreal injections and seems to develop mainly in the context of the off-label use of drugs that have not been conceived for intravitreous administration. The aetiology of sterile endophthalmitis, independently of the administered drug, remains uncertain and a multifactorial origin cannot be discarded. Sterile inflammation secondary both to intravitreal triamcinolone acetonide and to intravitreal bevacizumab share many characteristics such as the acute and painless vision loss present in the big majority of the cases. Dense vitreous opacity is a common factor, while anterior segment inflammation appears to be mild to moderate. In eyes with sterile endophthalmitis, visual acuity improves progressively as the intraocular inflammation reduces without any specific treatment. If by any chance the ophthalmologist is not convinced by the sterile origin of the inflammation, this complication must be treated as an acute endophthalmitis because of the devastating visual prognosis of this intraocular infection in the absence of therapy.

    The present disclosure provides methods, recombinant DNA molecules, recombinant host cells containing the DNA molecules, and transgenic plant cells, plant tissue and plants which contain and express at least one antisense or interference RNA specific for a thiamine biosynthetic coding sequence or a thiamine binding protein or a thiamine-degrading protein, wherein the RNA or thiamine binding protein is expressed under the regulatory control of a transcription regulatory sequence which directs expression in male and/or female reproductive tissue. These transgenic plants are conditionally sterile; i.e., they are fertile only in the presence of exogenous thiamine. Such plants are especially appropriate for use in the seed industry or in the environment, for example, for use in revegetation of contaminated soils or phytoremediation, especially when those transgenic plants also contain and express one or more chimeric genes which confer resistance to contaminants.

    Insect pests have caused an increasing problem in agriculture and human health through crop losses and disease transmission to man and livestock. Intervention to ensure food security and human health has relied on Integrated Pest Management (IPM) strategies to keep the pests population below economic injury levels. IPM integrate a variety of methods, but there has been over-reliance on chemical control following the discovery of insecticidal properties of DDT. It is now realized that, maintaining pest populations at controlled levels is unsustainable and eradication options is now being considered. Although the Sterile Insect Technique(SIT) could be used for insect suppression, it is gaining favour in the elimination (eradication) of the target pest population through Areawide-based IPM (Author)

    This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.

    1977-01-15

    On the basis of a survey is attempted to describe mode of development, symptomatology, individual forms and the different possibilities of therapy of the spontaneous hypoglycaemias. A particularly broad range was devoted to the cerebral sequelae, since in these cases--according to our experience--on account of simulation of neurologico-psychiatric symptoms at the soonest wrong diagnoses are to be expected. Furthermore, it is attempted to classify the hypoglycemias according to their development, in which cases their incompleteness was evident from the very beginning. The individual forms of appearance are treated according their to significance. Out of the inducible hypoglycaemias a particular attention is devoted to the forms caused by insulin and oral antidiabetics, since these most frequently participate in the development. Finally the author inquires into diagnostic measures for recognition of special forms of hypoglycaemia. In this place the diagnostics of hyperinsulinism conditioned by adenomatosis or tumours of other kinds is of particular importance. Finally conservative and operative possibilities of the therapy of these tumours are discussed,whereby the only recently tested treatment with streptotocin is mentioned.

    The decision to seek an abortion is never easy. Women have different reasons for choosing an abortion and their social, economic and religious background may influence how they cope. Furthermore, once pregnant, the alternatives of childbirth and adoption or keeping the baby may not be psychologically neutral. Research studies in this area have been hampered by methodological problems, but most of the better-quality studies have shown no increased risk of mental health problems in women having an abortion. A consistent finding has been that of pre-existing mental illness and subsequent mental health problems after either abortion or childbirth. Furthermore, studies have shown that only a minority of women experience any lasting sadness or regret. Risk factors for this include ambivalence about the decision, level of social support and whether or not the pregnancy was originally intended. More robust, definitive research studies are required on mental health after abortion and alternative outcomes such as childbirth. Copyright 2010 Elsevier Ltd. All rights reserved.

    A case of inversion of the uterus following abortion is reported. The 35-year old patient, admitted October 10, 1978 to the Medical College and Hospitals in Calcutta, India was referred by a private practitioner with a history of amenorrhea for 16 weeks, bleeding for 3 days, expulsion of the fetus 3 days earlier, and something coming down per vaginum for 2 days. The patient was para 4+0 (all full term normal deliveries) and home delivery for the last child 1 1/2 years earlier. She had a history of regular menstrual periods. Her general condition was poor. The examination revealed a gangrenous mass coming out of the vulva with a very offensive smell. There was a raw surface on which placenta like tissue was attached. No active bleeding was seen. Fundus and cervix of the uterus could not be felt. On rectal examination the uterus could not be felt, a cup-like depression was felt at the site of the uterus. The provision diagnosis was inversion of uterus following abortion. Treatment was started with sedatives and antibiotics, and arrangements were made for a blood transfusion. The vaginal mass was covered with glycerine and acriflavine gauze, and a hysterectomy was decided upon after improvement of her general condition and control of the infection. On October 14th, the patient was placed in knee chest position and posterior vaginal wall was retracted with Sims' speculum when the inverted lump was spontaneously reduced within the vagina. The inverted uterus was felt in the region of the vaginal vault. Glycerine acriflavine pack was given which was taken out and repack was given daily until the operation. The hysterectomy was performed on October 23rd. The abdomen was opened up by a transverse incision and the pelvis was explored. In the region of the uterus a cup-shaped depression was noted. Tubes and ovaries of both sides were seen hanging laterally from the cupped area. The left tube was found congested and thickened. Reduction of uterus was done by making a vertical

    Abortion, spontaneous or induced, is a common complication of pregnancy and exploration of available and safe regimens for medical abortion in developing countries seems crucial. The present study was aimed to assess the effect of letrozole in combination with misoprostol in women eligible for legal therapeutic abortion with gestational age ≤14weeks. This clinical randomized trial was conducted on 78 women who were candidate of medical abortion and eligible for legal abortion with gestational age ≤14 weeks that were randomly divided into two groups of case and controls. Case group received daily oral dose of 10mg letrozole for three days followed by vaginal misoprostol. In control group the patients received only vaginal misoprostol. The rate of complete abortion, induction-of-abortion time, and side-effects were assessed. Complete abortion was observed in 30 patients (76.9%) in case group and 9 (23.1%) cases were failed. In control group there was 16 (41.03%) complete abortions and 23 (58.97%) cases were failed to abort. Patients with gestational age of between 6 and 10 weeks did not show significant difference in both groups (P=0.134). Regarding pregnancy remnants there were significant differences between two groups (P=0.034). The time form admission to discharge in case groups were significantly shorter than those in control group (P=0.001). The indication for curettage in case group was significantly less than control group (P=0.001). A 3-day course of letrozole (10mg/daily) followed by misoprostol was associated with a higher complete abortion and lower curettage rates and reduction in time from admission to discharge in women with gestational age ≤14 weeks compared to misoprostol alone.

    2007-01-01

    Background and Objectives: The safety and efficacy of female hysteroscopic sterilization using the Essure system has been well documented. Given the marked differences in the execution of hysteroscopic and laparoscopic sterilization, the objective of this study was to assess the experience of pain postprocedure between the 2. Secondary end-points included postoperative pain medication, time to return to normal activities, postprocedure bleeding, and patient satisfaction. Methods: Twenty cases each of laparoscopic sterilization (LS) and hysteroscopic sterilization (HS) were performed. Patients were surveyed regarding their experience of pain immediately postoperatively, 1 week, and 4 weeks post-procedure. Results: The average pain score immediately postprocedure was significantly lower among HS patients than among LS patients (t=−8.17, P<.0001). One-week post-procedure, none of the patients in the HS group reported any pain, while the average pain score among the LS patients was 2.65 (t =−9.67, P<.0001). Four weeks post-procedure, women in the HS group continued to report no pain, 35% of the LS group continued to report some pain (t=−3.04, P=.004). Conclusions: Hysteroscopic sterilization offers a minimally invasive, less painful, equally efficacious modality for sterilization than laparoscopic sterilization and should be available to all women seeking permanent birth control.

  17. Sterile neutrinos as dark matter

    1994-01-01

    The simplest model that can accommodate a viable nonbaryonic dark matter candidate is the standard electroweak theory with the addition of right-handed (sterile) neutrinos. We consider a single generation of neutrinos with a Dirac mass μ and a Majorana mass M for the right-handed component. If M much-gt μ (standard hot dark matter corresponds to M=0), then sterile neutrinos are produced via oscillations in the early Universe with energy density independent of M. However, M is crucial in determining the large scale structure of the Universe; for M∼100 eV, sterile neutrinos make an excellent warm dark matter candidate

  19. Legalized abortion: a public health success story.

    1999-06-01

    60% of more than 2000 women surveyed by the Picker Institute who underwent induced abortion procedures rated the quality of their care as excellent. Another third reported their care as being either very good or good. The survey also found that the quality of abortion care is comparable to other outpatient surgery. However, the high quality of care women receive from abortion providers is lost in the hostile anti-abortion climate created by threatening protesters outside of clinics and the murder of 7 clinic workers and physicians who performed abortions. Abortion opponents fail to acknowledge that legal abortion is a medical procedure which protects women's health and saves their lives. Before abortion was legalized in the US, countless women were either rendered unable to reproduce or died from abortion-related complications. Efforts to outlaw abortion persist despite it being widely recognized by medical experts as one of the most safe medical procedures currently performed in the US. When state legislatures target abortion providers with unduly strict regulations, abortion becomes prohibitively expensive and difficult to obtain.

    cancer was associated with a spontaneous abortion (RR = 0.9; 95% CI = 0.7-1.2). Our data support the hypothesis that an induced abortion can adversely influence a woman's subsequent risk of breast cancer. However, the results across all epidemiologic studies of this premise are inconsistent--both overall and within specific subgroups. The risk of breast cancer should be reexamined in future studies of women who have had legal abortion available to them throughout the majority of their reproductive years, with particular attention to the potential influence of induced abortion early in life.

    Terminal deletions induced by ionizing radiations in Petunia are not sexually transmitted. Cytogenetic study of plants with a heterozygous deletion and their progenies shows that this lack of transmission is accompanied by a gametic semi-sterility due to the fact that gametes carrying the deleted chromosome are not viable. The interest of such a male sterility with a gametophytic determinism for the study of sporophyte-gametophyte relationships is underlined.

  2. [About da tai - abortion in old Chinese folk medicine handwritten manuscripts].

    2013-01-01

    Of 881 Chinese handwritten volumes with medical texts of the 17th through mid-20th century held by Staatsbibliothek zu Berlin and Ethnologisches Museum Berlin-Dahlem, 48 volumes include prescriptions for induced abortion. A comparison shows that these records are significantly different from references to abortion in Chinese printed medical texts of pre-modern times. For example, the percentage of recipes recommended for artificial abortions in handwritten texts is significantly higher than those in printed medical books. Authors of handwritten texts used 25 terms to designate artificial abortion, with the term da tai [see text], lit.: "to strike the fetus", occurring most frequently. Its meaning is well defined, in contrast to other terms used, such as duo tai [see text], lit: "to make a fetus fall", xia tai [see text], lit. "to bring a fetus down", und duan chan [see text], lit., to interrupt birthing", which is mostly used to indicate a temporary or permanent sterilization. Pre-modern Chinese medicine has not generally abstained from inducing abortions; physicians showed a differentiating attitude. While abortions were descibed as "things a [physician with an attitude of] humaneness will not do", in case a pregnancy was seen as too risky for a woman she was offered medication to terminate this pregnancy. The commercial application of abortifacients has been recorded in China since ancient times. A request for such services has continued over time for various reasons, including so-called illegitimate pregnancies, and those by nuns, widows and prostitutes. In general, recipes to induce abortions documented in printed medical literature have mild effects and are to be ingested orally. In comparison, those recommended in handwritten texts are rather toxic. Possibly to minimize the negative side-effects of such medication, practitioners of folk medicine developed mechanical devices to perform "external", i.e., vaginal approaches.

  3. Food irradiation and sterilization

    Science.gov (United States)

    Josephson, Edward S.

    Radiation sterilization of food (radappertization) requires exposing food in sealed containers to ionizing radiation at absorbed doses high enough (25-70 kGy) to kill all organisms of food spoilage and public health significance. Radappertization is analogous to thermal canning is achieving shelf stability (long term storage without refrigeration). Except for dry products in which autolysis is negligible, the radappertization process also requires that the food be heated to an internal temperature of 70-80°C (bacon to 53°C) to inactivate autolytic enzymes which catalyze spoilage during storage without refrigeration. To minimize the occurence of irradiation induced off-flavors and odors, undesirable color changes, and textural and nutritional losses from exposure to the high doses required for radappertization, the foods are vacuum sealed and irradiated frozen (-40°C to -20°C). Radappertozed foods have the characteristic of fresh foods prepared for eating. Radappertization can substitute in whole or in part for some chemical food additives such as ethylene oxide and nitrites which are either toxic, carcinogenic, mutagenic, or teratogenic. After 27 years of testing for "wholesomeness" (safety for consumption) of radappertized foods, no confirmed evidence has been obtained of any adverse effecys of radappertization on the "wholesomeness" characteristics of these foods.

    Tanzania has one of the highest maternal mortality ratios in the world, and unsafe abortion is one of its leading causes. Yet little is known about its incidence. To provide the first ever estimates of the incidence of unsafe abortion in Tanzania, at the national level and for each of the 8 geopolitical zones (7 in Mainland plus Zanzibar). A nationally representative survey of health facilities was conducted to determine the number of induced abortion complications treated in facilities. A survey of experts on abortion was conducted to estimate the likelihood of women experiencing complications and obtaining treatment. These surveys were complemented with population and fertility data to obtain abortion numbers, rates and ratios, using the Abortion Incidence Complications Methodology. In Tanzania, women obtained just over 405,000 induced abortions in 2013, for a national rate of 36 abortions per 1,000 women age 15-49 and a ratio of 21 abortions per 100 live births. For each woman treated in a facility for induced abortion complications, 6 times as many women had an abortion but did not receive care. Abortion rates vary widely by zone, from 10.7 in Zanzibar to 50.7 in the Lake zone. The abortion rate is similar to that of other countries in the region. Variations by zone are explained mainly by differences in fertility and contraceptive prevalence. Measures to reduce the incidence of unsafe abortion and associated maternal mortality include expanding access to post-abortion care and contraceptive services to prevent unintended pregnancies.

  9. Food packaging and radiation sterilization

    International Nuclear Information System (INIS)

    Kawamura, Yoko

    1998-01-01

    Radiation sterilization has several merits that it is a positively effective sterilization method, it can be used to sterilize low heat-resistant containers and high gas barrier films, and there is no possibility of residual chemicals being left in the packages. It has been commercially used in 'Bag in a Box' and some food containers. The γ ray and an electron beam are commonly used in radiation sterilization. The γ ray can sterilize large size containers and containers with complex shapes or sealed containers due to its strong transmission capability. However, since the equipment tends to be large and expensive, it is generally used in off production lines. On the other hand, it is possible to install and electron beam system on food production lines since the food can be processed in a short time due to its high beam coefficient and its ease of maintenance, even though an electron beam has limited usage such as sterilizing relatively thin materials and surface sterilization due to the weak transmission. A typical sterilization dose is approximately 10-30 kGy. Direct effects impacting packaging materials, particularly plastics, include scission of polymer links, cross-linkage between polymers, and generating radiolysis products such as hydrogen, methane, aliphatic hydrocarbons, etc. Furthermore, under the existence of oxygen, the oxygen radicals generated by the radiation will oxidize and peroxidize polymer chains and will generate alcohol and carbonyl groups, which shear polymer links, and generate oxygen containing low molecular compounds. As a result, degradation of physical strength such as elongation and seal strength, generating foreign odor, and an increase in global migration values shown in an elution test are sometimes evident. The food packages have different shapes, materials, additives, number of microorganisms and purpose. Therefor the effects of radiation, the optimum dose and so on must be investigated on the individual package. (J.P.N.)

  10. Spontaneous Pneumothorax

    Full Text Available History of present illness: A 16-year-old male with asthma was brought to the emergency department by his parents for increasing right-sided chest pain associated with cough and mild dyspnea over the past week. Albuterol inhaler did not provide relief. He denied recent trauma, fever, sweats, and chills. The patient’s vitals and oxygen saturations were stable. Physical exam revealed a tall, slender body habitus with no signs of chest wall injuries. Bilateral breath sounds were present, but slightly diminished on the right. A chest radiograph was ordered to determine the etiology of the patient’s symptoms. Significant findings: Initial chest radiograph showed a 50% right-sided pneumothorax with no mediastinal shift, which can be identified by the sharp line representing the pleural lung edge (see arrows and lack of peripheral lung markings extending to the chest wall. While difficult to accurately estimate volume from a two-dimensional image, a 2 cm pneumothorax seen on chest radiograph correlates to approximately 50% volume.1 The patient underwent insertion of a pigtail pleural drain on the right and repeat chest radiograph showed resolution of previously seen pneumothorax. Ultimately the pigtail drain was removed and chest radiograph showed clear lung fields without evidence of residual pneumothorax or pleural effusion. Discussion: Pneumothorax is characterized by air between the lungs and the chest wall.2 Spontaneous pneumothorax (SP occurs when the pneumothorax is not due to trauma or any discernable etiology. 3 SP is multifactorial and may be associated with subpleural blebs, bullae, and other connective tissue changes that predispose the lungs to leak air into the pleural space.4 SP can be further subdivided into primary (no history of underlying lung disease or secondary (history of chronic obstructive pulmonary disease, tuberculosis, cystic fibrosis, lung malignancy, etc..2 It is estimated that the incidence of SP among US pediatric

    Comparisons of the efficacy of different regimens of medical abortion are difficult because of the widely varying protocols (even for testing identical regimens), divergent definitions of success and failure, and lack of a standard method of analysis. In this article we review the current efficacy literature on medical abortion, highlighting some of the most important differences in the way that efficacy has been analyzed. We then propose a standard conceptual approach and the accompanying statistical methods for analyzing clinical trials of medical abortion and to explain how clinical investigators can implement this approach. Our review reveals that research on the efficacy of medical abortion has closely followed the conceptual model used for analysis of surgical abortion. The problem, however, is that, whereas surgical abortion is a discrete event occurring in the space of a few minutes or less, medical abortion is a process typically lasting from several days to several weeks. In this process, two events may occur that are not possible with surgical abortion. First, the woman can opt out of the process before a fair determination of efficacy can be made. Second, the process of medical abortion allows time for surgical interventions that may be convenient for the clinician but not strictly necessary from a medical perspective. Another difference from surgical abortions is that, for medical abortions, different medical abortion protocols specify different waiting periods, giving the drugs less time to work in some studies than in others before a determination of efficacy is made. We argue that, when analyzing efficacy of medical abortion, researchers should abandon their close reliance on the analogy to surgical abortion. In fact, medical abortion is more appropriately analyzed by life table procedures developed for the study of another fertility regulation technology; contraception. As with medical abortion, a woman initiating use of a contraceptive method can

  12. Abortion trends from 1996 to 2011 in Estonia: special emphasis on repeat abortion

    Background The study aimed to describe the overall and age-specific trends of induced abortions from 1996 to 2011 with an emphasis on socio-demographic characteristics and contraceptive use of women having had repeat abortions in Estonia. Methods Data were retrieved from the Estonian Medical Birth and Abortion Registry and Statistics Estonia. Total induced abortion numbers, rates, ratios and age-specific rates are presented for 1996–2011. The percentage change in the number of repeat abortions within selected socio-demographic subgroups, contraception use and distribution of induced abortions among Estonians and non-Estonians for the first, second, third, fourth and subsequent abortions were calculated for the periods 1996–2003 and 2004–2011. Results Observed trends over the 16-year study period indicated a considerable decline in induced abortions with a reduction in abortion rate of 57.1%, which was mainly attributed to younger cohorts. The percentage of women undergoing repeat abortions fell steadily from 63.8% during 1996–2003 to 58.0% during 2004–2011. The percentage of women undergoing repeat abortions significantly decreased over the 16 years within all selected socio-demographic subgroups except among women with low educational attainment and students. Within each time period, a greater percentage of non-Estonians than Estonians underwent repeat abortions and obtained third and subsequent abortions. Most women did not use any contraceptive method prior to their first or subsequent abortion. Conclusion A high percentage of women obtaining repeat abortions reflects a high historical abortion rate. If current trends continue, a rapid decline in repeat abortions may be predicted. To decrease the burden of sexual ill health, routine contraceptive counselling, as standard care in the abortion process, should be seriously addressed with an emphasis on those groups - non-Estonians, women with lower educational attainment, students and women with children

    In the treatment of burns or accidental loss of skin, cadaveric skin allografts provide an alternative to temporarily cover a wounded area. The skin bank facility is indispensable for burn care. The first human skin bank was established in Argentina in 1989; later, 3 more banks were established. A careful donor selection is carried out according to the national regulation in order to prevent transmissible diseases. As cadaveric human skin is naturally highly contaminated, a final sterilization is necessary to reach a sterility assurance level (SAL) of 10 -6. The sterilization dose for 106 batches of processed human skin was determined on the basis of the Code of Practice for the Radiation Sterilization of Tissue Allografts: Requirements for Validation and Routine Control (2004) and ISO 11137-2 (2006). They ranged from 17.6 to 33.4 kGy for bioburdens of >10-162.700 CFU/100 cm 2. The presence of Gram negative bacteria was checked for each produced batch. From the analysis of the experimental results, it was observed that the bioburden range was very wide and consequently the estimated sterilization doses too. If this is the case, the determination of a tissue-specific dose per production batch is necessary to achieve a specified requirement of SAL. Otherwise if the dose of 25 kGy is preselected, a standardized method for substantiation of this dose should be done to confirm the radiation sterilization process.

    An on-going debate of whether or not to legalize abortion has not stopped the number of abortion cases decreases. New practices of abortion such as online abortion has been a growing trend among teenagers. This study aims to determine how teenagers use social media such as Facebook, YouTube and Wikipedia for the practice of abortion. This study adopted online research methods (ORMs), a qualitative approach 2.0 by hacking analytical perspective developed. This study establishes online teen abortion as a research subject. This study finds patterns of online abortions among teenagers covering characteristics of teenagers as perpetrators, styles of communication, and their implication toward policy, particularly Electronic Transaction Information (ETI) regulation. Implications for online abortion behavior among teenagers through social media. The potential abortion client especially girls find practical, fast, effective, and efficient solutions that keep their secret. One of prevention patterns that has been done by some people who care about humanity and anti-abortion in the online world is posting a anti-abortion text, video or picture, anti-sex-free (anti -free intercourse before marriage) in an interesting, educative, and friendly ways.

    Since the legalization of abortion services in the United States, provision of abortions has remained a controversial issue of high political interest. Routine abortion training is not offered at all obstetrics and gynecology (Ob-Gyn) training programs, despite a specific training requirement by the Accreditation Council for Graduate Medical Education. Previous studies that described Ob-Gyn programs with routine abortion training either examined associations by using national surveys of program directors or described the experience of a single program. We set out to identify enablers of and barriers to Ob-Gyn abortion training in the context of a New York City political initiative, in order to better understand how to improve abortion training at other sites. We conducted in-depth qualitative interviews with 22 stakeholders from 7 New York City public hospitals and focus group interviews with 62 current residents at 6 sites. Enablers of abortion training included program location, high-capacity services, faculty commitment to abortion training, external programmatic support, and resident interest. Barriers to abortion training included lack of leadership continuity, leadership conflict, lack of second-trimester abortion services, difficulty obtaining mifepristone, optional rather than routine training, and antiabortion values of hospital personnel. Supportive leadership, faculty commitment, and external programmatic support appear to be key elements for establishing routine abortion training at Ob-Gyn residency training programs.

    From 1980 through 1991, the number of legal induced abortions reported to CDC remained stable, varying each year by 1969, CDC has compiled abortion data received from 52 reporting areas: 50 states, the District of Columbia, and New York City. In 1991, 1,388,937 abortions were reported--a 2.8% decrease from 1990. The abortion ratio was 339 legal induced abortions per 1,000 live births, and the abortion rate was 24 per 1,000 women 15-44 years of age. Women who were undergoing an abortion were more likely to be young, white, and unmarried; most had had no previous live births and had been obtaining an abortion for the first time. More than half (52%) of all abortions were performed at or before the 8th week of gestation, and 88% were before the 13th week. Younger women (i.e., women may partially account for this decline. An accurate assessment of the number and characteristics of women who obtain abortions in the United States is necessary both to monitor efforts to prevent unintended pregnancy and to identify and reduce preventable causes of morbidity and mortality associated with abortions.

    This survey of studies which relate to the emotional sequelae of induced abortion, draws attention to the need for more long-term, in-depth prospective studies. The literature to this point finds no psychiatric indications for abortion, and no satisfactory evidence that abortion improves the psychological state of those not mentally ill; abortion is contra-indicated when psychiatric disease is present, as mental ill-health has been shown to be worsened by abortion. Recent studies are turning up an alarming rate of post-abortion complications such as P.I.D., and subsequent infertility. The emotional impact of these complications needs to be studied. Other considerations looked at are the long-term demographic implications of abortion on demand and the effect on the medical professions.

  20. [Legal and illegal abortion in Switzerland].

    Aspects of legal and illegal abortion in Switzerland are discussed. About 110,000 births, 25,000 therapeutic abortions (75% for psychiatric indications) and an estimated 50,000 illegal abortions occur annually in Switzerland. Although the mortality and morbidity of therapeutic aborti on are similar to those of normal births (1.4 per 1000 and 11%, respectively) the mortality and morbidity of criminal abortions are far greater (3 per 1000 and 73%, respectively). In the author's view, too strict an interpretatiok of Swiss abortion law (which permits abortion to avoid serious harm to the mother's health) does not take into account the severe and lasting emotional and psychological damage which may be caused by unwanted pregnancy, birth, and childraising. In the present social situation, the social and psychological support required by these women is not available; until it is, abortion is to be preferred.

    The early medical literature on mental health outcomes following abortion is fraught with methodological flaws that can improperly influence clinical practice. Our goal is to review the current medical literature on depression and other mental health outcomes for women obtaining abortions. The Turnaway Study prospectively enrolled 956 women seeking abortion in the USA and followed their mental health outcomes for 5 years. The control group was comprised of women denied abortions based on gestational age limits, thereby circumventing the major methodological flaw that had plagued earlier studies on the topic. Rates of depression are not significantly different between women obtaining abortion and those denied abortion. Rates of anxiety are initially higher in women denied abortion care. Counseling on decision-making for women with unintended pregnancies should reflect these findings.

  2. Induced abortion and contraception in Italy.

    1991-09-01

    This article discusses the legal and epidemiologic status of abortion in Italy, and its relationship to fertility and contraception. Enacted in May 1978, Italy's abortion law allows the operation to be performed during the 1st 90 days of gestation for a broad range of health, social, and psychological reasons. Women under 18 must receive written permission from a parent, guardian, or judge in order to undergo an abortion. The operation is free of charge. Health workers who object to abortion because of religious or moral reasons are exempt from participating. Regional differences exist concerning the availability of abortion, easy to procure in some places and difficult to obtain in others. After an initial increase following legalization, the abortion rate was 13.5/1000 women aged 15-44 and the abortion ratio was 309/1000 live births -- an intermediate rate and ratio compared to other countries. By the time the Abortion Act of 1978 was adopted, Italy already had one of the lowest fertility levels in Europe. Thus, the legalization of abortion has had no impact on fertility trends. Contrary to initial fears that the legalization of abortion would make abortion a method of family planning, 80% of the women who sought an abortion in 1983-88 were using birth control at the time (withdrawal being the most common method used by this group). In fact, most women who undergo abortions are married, between the ages of 25-34, and with at least one child. Evidence indicates widespread ignorance concerning reproduction. In a 1989 survey, only 65% of women could identify the fertile period of the menstrual cycle. Italy has no sex education in schools or national family planning programs. Compared to most of Europe, Italy still has low levels of reliable contraceptive usage. This points to the need to guarantee the availability of abortion.

    Intersubspecific autotetraploid rice (Oryza sativa ssp. indica × japonica) hybrids have greater biological and yield potentials than diploid rice. However, the low fertility of intersubspecific autotetraploid hybrids, which is largely caused by high pollen abortion rates, limits their commercial utility. To decipher the cytological and molecular mechanisms underlying allelic interactions in autotetraploid rice, we developed an autotetraploid rice hybrid that was heterozygous (S(i)S(j)) at F1 pollen sterility loci (Sa, Sb, and Sc) using near-isogenic lines. Cytological studies showed that the autotetraploid had higher percentages (>30%) of abnormal chromosome behavior and aberrant meiocytes (>50%) during meiosis than did the diploid rice hybrid control. Analysis of gene expression profiles revealed 1,888 genes that were differentially expressed between the autotetraploid and diploid hybrid lines at the meiotic stage, among which 889 and 999 were up- and down-regulated, respectively. Of the 999 down-regulated genes, 940 were associated with the combined effect of polyploidy and pollen sterility loci interactions (IPE). Gene Ontology enrichment analysis identified a prominent functional gene class consisting of seven genes related to photosystem I (Gene Ontology 0009522). Moreover, 55 meiosis-related or meiosis stage-specific genes were associated with IPE in autotetraploid rice, including Os02g0497500, which encodes a DNA repair-recombination protein, and Os02g0490000, which encodes a component of the ubiquitin-proteasome pathway. These results suggest that polyploidy enhances epistatic interactions between alleles of pollen sterility loci, thereby altering the expression profiles of important meiosis-related or meiosis stage-specific genes and resulting in high pollen sterility. © 2015 American Society of Plant Biologists.

    Usable male sterility systems have immense potential in developing hybrid varieties in crop plants, which can also be used as a biological safety containment to prevent horizontal transgene flow. Barnase-Barstar system developed earlier was the first approach to engineer male sterility in plants. In an analogous situation, we have evolved a system of inducing pollen abortion and male sterility in transgenic tobacco by expressing a plant gene coding for a protein with known developmental function in contrast to the Barnase-Barstar system, which deploys genes of prokaryotic origin, i.e., from Bacillus amyloliquefaciens. We have used a plant pathogen-induced gene, cysteine protease for inducing male sterility. This gene was identified in the wild peanut, Arachis diogoi differentially expressed when it was challenged with the late leaf spot pathogen, Phaeoisariopsis personata. Arachis diogoi cysteine protease (AdCP) was expressed under the strong tapetum-specific promoter (TA29) and tobacco transformants were generated. Morphological and histological analysis of AdCP transgenic plants showed ablated tapetum and complete pollen abortion in three transgenic lines. Furthermore, transcript analysis displayed the expression of cysteine protease in these male sterile lines and the expression of the protein was identified in western blot analysis using its polyclonal antibody raised in the rabbit system.

    This study aims to assess the prevalence of and factors associated with induced abortion among married women in rural areas of Anhui Province, China. A multistage probability sampling method was used to identify a representative sample of 53,652 married women aged 18-49 years in rural areas of Anhui Province, China. All women were interviewed in the form of a standardized questionnaire. We found that 32.0% (16,800) of these women had had at least one induced abortion: 21.1% (11,090) of women had had one; 7.6% (3976) of women had had two; and 4.1% (1734) of women had had at least three. The number of induced abortions per 100 pregnancies was found to be 22.0. Multivariate analysis showed that education, the age of a woman at her first marriage, number of total births, number of total pregnancies, and contraceptive methods were significant predictors for induced abortion after controlling for women's current age, employment and family yearly income. The study shows that the prevalence of induced abortion is still very high among married women in rural China, and highly effective methods of contraception (sterilization, intrauterine device) decrease women's recourse to induced abortion. © 2014 The Authors.

    Popular discourse on abortion in film and television assumes that abortions are under- and misrepresented. Research indicates that such representations influence public perception of abortion care and may play a role in the production of social myths around abortion, with consequences for women's experience of abortion. To date, abortion plotlines in American film and television have not been systematically tracked and analyzed. A comprehensive online search was conducted to identify all representations of pregnancy decision making and abortion in American film and television through January 2013. Search results were coded for year, pregnancy decision and mortality outcome. A total of 310 plotlines were identified, with an overall upward trend over time in the number of representations of abortion decision making. Of these plotlines, 173 (55.8%) resulted in abortion, 80 (25.8%) in parenting, 13 (4.2%) in adoption and 21 (6.7%) in pregnancy loss, and 16 (5.1%) were unresolved. A total of 13.5% (n=42) of stories ended with the death of the woman who considered an abortion, whether or not she obtained one. Abortion-related plotlines occur more frequently than popular discourse assumes. Year-to-year variation in frequency suggests an interactive relationship between media representations, cultural attitudes and policies around abortion regulation, consistent with cultural theory of the relationship between media products and social beliefs. Patterns of outcomes and rates of mortality are not representative of real experience and may contribute to social myths around abortion. The narrative linking of pregnancy termination with mortality is of particular note, supporting the social myth associating abortion with death. This analysis empirically describes the number of abortion-related plotlines in American film and television. It contributes to the systematic evaluation of the portrayal of abortion in popular culture and provides abortion care professionals and

Our aim was to investigate the key determinants of induced abortion in a sample of women who sought postabortion care. Materials and methods: A cross-sectional household survey was carried out from February to September 2012 in Ouagadougou, Burkina Faso. Data of 37 women who had had an induced abortion and 267 women who had had a spontaneous abortion were prospectively collected on sociodemographic characteristics, pregnancy and birth history, abortion experience, including previous abortion experience, and selected clinical information, including the type of abortion. A two-step regression analysis consisting of a univariate and a multivariate logistic regression was run on Stata version 11.2 in order to identify the key determinants of induced abortion. Results: The findings indicated that 12% of all abortions were certainly induced. Three key factors were significantly and positively associated with the probability of having an induced abortion: whether the woman reported that her pregnancy was unwanted (odds ratio [OR] 10.45, 95% confidence interval [CI] 3.59–30.41; whether the woman reported was living in a household headed by her parents (OR 6.83, 95% CI 2.42–19.24; and if the woman reported was divorced or widowed (OR 3.47, 95

  12. Anti-abortion policy leads to more abortions.

    In 1984, the Reagan administration announced in Mexico City a reversal in the US international family planning policy. The new policy strictly forbids any international family planning group that receives US funds from providing abortion services or counseling. An immediate impact on family planning programs in developing countries was that it prevented the opening of much needed clinics in the poorest, most rapidly growing countries in the world, such as Bangladesh. The University of Michigan School of Public Health estimates an additional 380,000 unwanted pregnancies, resulting in 311,000 births, 69,000 abortions, and 1200 maternal deaths in the next 3 years. Not only did the US change its policy, but congress decreased funding for international family planning programs 20% between 1985 and 1987. The majority of the funding goes to the US Agency for International Development (USAID), and in 1988 the Reagan administration allowed USAID to funnel about $75 million of this money to other projects, e.g. general African development fund. Fewer contraceptives are available due to the reduced funding, and therefore more women seek an abortion as a last resort against unwanted pregnancy. An additional effect of this 1984 policy reversal is that fewer nongovernmental organizations (NGOs) are eligible for grants, so USAID gives its family planning funds to government agencies who are not the most effective users of funds and are not always trusted by the people served.

    Unsafe abortion is affecting a lot, in health, socio-economic and health care cost of many countries. Despite invention of simple technology and scientifically approved safe abortion methods, women and girls are still using unsafe abortion practices. Since 2002, Nepal has achieved remarkable progress in developing policies, guidelines, task shifting, training human resources and increasing access to services. However, more than half of abortion in Nepal are performed clandestinely by untrained or unapproved providers or induced by pregnant woman herself. Knowledge on legalization and availability of safe abortion service among women is still very poor. Stigma on abortion still persists among community people, service providers, managers, and policy makers. Access to safe abortion, especially in remote and rural areas, is still far behind as compared to their peers from urban areas. The existing law is not revised in the spirit of current Constitution of Nepal and rights-based approach. The existence of abortion stigma and the shifting of the government structure from unitary system to federalism in absence of a complete clarity on how the safe abortion service gets integrated into the local government structure might create challenge to sustain existing developments. There is, therefore, a need for all stakeholders to make a lot of efforts and allocate adequate resources to sustain current achievements and ensure improvements in creating a supportive social environment for women and girls so that they will be able to make informed decisions and access to safe abortion service in any circumstances.

  14. Is Induced Abortion Really Declining in Armenia?

    2016-06-01

    As in other post-Soviet settings, induced abortion has been widely used in Armenia. However, recent national survey data point to a substantial drop in abortion rates with no commensurate increase in modern contraceptive prevalence and no change in fertility levels. We use data from in-depth interviews with women of reproductive age and health providers in rural Armenia to explore possible underreporting of both contraceptive use and abortion. While we find no evidence that women understate their use of modern contraception, the analysis suggests that induced abortion might indeed be underreported. The potential for underreporting is particularly high for sex-selective abortions, for which there is growing public backlash, and medical abortion, a practice that is typically self-administered outside any professional supervision. Possible underreporting of induced abortion calls for refinement of both abortion registration and relevant survey instruments. Better measurement of abortion dynamics is necessary for successful promotion of effective modern contraceptive methods and reduction of unsafe abortion practices. © 2016 The Population Council, Inc.

    Lack of sewage treatment and adequate sanitation conditions can contribute to the proliferation of numerous parasitic and infectious diseases in addition to water degradation. Approximately fifty types of infections can be transmitted from a sick to a healthy person through different pathways involving human excreta. Untreated sewage can contaminate water, food, hands, soil, etc. Epidemics of certain diseases such as typhoid, cholera, dysenteries, etc., and countless cases of worms are responsible for high mortality rates in third world countries. In the work the different techniques of sewage treatment by disinfestation and sterilization were analyzed, highlighting the use and the advantages of the gamma radiation as well as the aspects of the radiological protection involved. The technique of sewage sterilization using gamma radiation is a method of controlling bacteria and microorganisms. It is estimated that more than 200 large irradiators are in operation worldwide, of which 5 are in Brazil, for general sterilization use. These facilities use a large amount of radioactive material, in the order of millions of Becquerel, for sterilization with high doses of radiation, which can generate lethal doses in a few minutes. These industrial facilities use Cobalt-60, being classified by the International Atomic Energy Agency - IAEA as Category 1 of high risk, and must possess a high level of radiological protection to carry out the sterilization, standing out the defense in depth. Specific legislation on radiological protection should be drafted for safe work and avoid future radiation accidents

    The sterilization of medical products by ionizing radiation is a well-established industrial process in a number of technologically advanced countries. It is indeed encouraging to note the rate of growth experienced during the past fifteen years. Starting with the first commercial plant in the early sixties in the USA there are to date more than sixty large facilities of this kind located in USA, Canada, Australia and the countries of Europe including USSR. The geographical distribution of these sterilization plants is rather unbalanced. In this respect Europe is far ahead of the other continents of the world, with about 65% of all sterilization plants, followed by North and South America with 17%, Asia with 8%, Australia and New Zealand with 9% and Africa with only 1%. During the last 10 years the IAEA has actively contributed to the development of radiation sterilization practices and technology in the Member States, with particular emphasis on the developing countries. Such promotional efforts have been made by (a) supporting co-ordinated research to accumulate relevant technical information, (b) organizing scientific meetings and training courses, (c) providing technical expertise in the form of fellowships and expert services, (d) providing technical assistance to conduct market surveys and economic feasibility assessment, (e) scientific publications, including technical manuals and proceedings reports, and (f) assistance in the formulation of an international 'Code of Practice' for standardization of the manufacturing practices for radiation sterilized medical products to meet the specified requirements of the various national Pharmacopoeias and of the international consumer market.

    1992-01-01

    Since radiation sterilization was first introduced in the United States in 1956 in the field of disposable medical devices, it has become an indispensable technique for sterilization because of the following reasons: (1) introduction into dialyzers, (2) introduction in medical device makers, (3) development of disposable medical devices associated with developing both high molecular chemistry and cool sterilization, (4) rationality of sterilization process, and (5) problems of sterilization with ethylene oxide gas. To promote the further development of radiation sterilization, the following items are considered necessary: (1) an increase in the number of facilities for radiation sterilization, (2) recommendation of the international standardization of sterilization method, (3) decrease in radiation doses associated with sterilization, (4) development of electron accelerators and bremsstrahlung equipments for radiation sources, and (5) simplification of sterilization process management. Factors precluding the development of radiation sterilization are: (1) development of other methods than radiation sterilization, (2) development of technique for sterile products, (3) high facility cost, (4) high irradiation cost, (5) benefits and limits of sterilization markets, and (6) influences of materials.

  18. Accounting for abortion: Accomplishing transnational reproductive governance through post-abortion care in Senegal.

    Science.gov (United States)

    2018-06-01

    Reproductive governance operates through calculating demographic statistics that offer selective truths about reproductive practices, bodies, and subjectivities. Post-abortion care, a global reproductive health intervention, represents a transnational reproductive regime that establishes motherhood as women's primary legitimate reproductive status. Drawing on ethnographic fieldwork conducted in Senegal between 2010 and 2011, I illustrate how post-abortion care accomplishes reproductive governance in a context where abortion is prohibited altogether and the US is the primary bilateral donor of population aid. Reproductive governance unfolds in hospital gynecological wards and the national health information system through the mobilization and interpretation of post-abortion care data. Although health workers search women's bodies and behavior for signs of illegal abortion, they minimize police intervention in the hospital by classifying most post-abortion care cases as miscarriage. Health authorities deploy this account of post-abortion care to align the intervention with national and global maternal health policies that valorize motherhood. Although post-abortion care offers life-saving care to women with complications of illegal abortion, it institutionalizes abortion stigma by scrutinizing women's bodies and masking induced abortion within and beyond the hospital. Post-abortion care reinforces reproductive inequities by withholding safe, affordable obstetric care from women until after they have resorted to unsafe abortion.

  19. Population Group Abortion Rates and Lifetime Incidence of Abortion: United States, 2008-2014.

    2017-12-01

    To assess the prevalence of abortion among population groups and changes in rates between 2008 and 2014. We used secondary data from the Abortion Patient Survey, the American Community Survey, and the National Survey of Family Growth to estimate abortion rates. We used information from the Abortion Patient Survey to estimate the lifetime incidence of abortion. Between 2008 and 2014, the abortion rate declined 25%, from 19.4 to 14.6 per 1000 women aged 15 to 44 years. The abortion rate for adolescents aged 15 to 19 years declined 46%, the largest of any group. Abortion rates declined for all racial and ethnic groups but were larger for non-White women than for non-Hispanic White women. Although the abortion rate decreased 26% for women with incomes less than 100% of the federal poverty level, this population had the highest abortion rate of all the groups examined: 36.6. If the 2014 age-specific abortion rates prevail, 24% of women aged 15 to 44 years in that year will have an abortion by age 45 years. The decline in abortion was not uniform across all population groups.

    2002-09-01

    The Soviet legacy of widespread reliance on induced abortion is of critical importance to reproductive trends and policies in post-Soviet nations, especially as they strive to substitute contraception for abortion. Using data from two Demographic and Health Surveys conducted in 1995 and 1999, this study analyzes and compares trends in abortion and contraception, women's attitudes toward abortion, and their perceptions of problems associated with abortion and contraception in Kazakhstan. Despite an overall decline in abortion and an increase in contraceptive use since Kazakhstan's independence in 1991, abortion has remained a prominent part of the country's reproductive culture and practices. This study shows how abortion-related views reflect the long-standing ethnocultural differences between the indigenous Kazakhs and Kazakhstan's residents of European roots, as the latter continue to have significantly higher levels of abortion. The study, however, also reveals the internal diversity among Kazakhs with respect to abortion experiences and views, stemming from decades of the Soviet sociocultural influence in Kazakhstan. In addition, the analysis points to some generational differences in views concerning abortion and contraception. Finally, the study demonstrates parallels in attitudes toward abortion and toward contraception, thereby questioning straightforward assumptions about the replacement of abortion with contraception.

    During the RHIC Au-run in 2001 the 200 MHz storage cavity system was used for the first time. The rebucketing procedure caused significant beam debunching in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam could account for approximately 30%-40% of the total beam intensity. Some of it will be in the abort gap. In order to minimize the risk of magnet quenching due to uncontrolled beam losses at the time of a beam dump, a combination of a fast transverse kicker and copper collimators were used to clean the abort gap. This report gives an overview of the gap cleaning procedure and the achieved performance

    Full Text Available I have published more than just a few papers on the abortion issue. Instead of taking either the pro choice or the pro life position, I offer a third alternative: evictionism. I claim that this perspective, which, as it happens is a principled compromise between the other two positions, is the only one compatible with libertarianism. Wisniewski (2010 offers several not unreasonable challenges to my thesis. The present paper is my attempt to refute each and every one of them.

  3. Politics and abortion in Bulgaria.

    Science.gov (United States)

    Sirakova, K

    1992-01-01

    Political change in Bulgaria has meant the beginning of the recognition of the reproduction rights of women. Abortion, for example, was legalized in 1990. Women in Bulgaria, however, still lack the information they need on basic hygiene and sex. It is impossible to promulgate a progressive strategy in Bulgaria if one ignores the isolation of the Turkish and Gypsy ethnic communities. In addition, an economic crisis exists, and no real measures have been undertaken to mitigate the situation. The new democratic institutions have settled comfortably into the structures of the former communist rule, even to the point of adopting the same extensive demagogic terminology which perpetrates the old gap between words and deeds. For example, although a new birth control strategy and plan for sex education was announced 2 years ago, nothing definite has been done. One development, however, has been the legalization of abortion, which was accompanied by an immediate drop in the abortion rate (still 1.5 abortions/birth). Because of a lack of sex education, 900 children are born to girls under age 15 each year. Bulgaria is just starting to embrace modern values and must update its attitudes towards women. Bulgaria's formal institutions seem to be unable to face this issue, and many societies and foundations have emerged to work for women's rights, to protect out-of-wedlock children, and to fight disease (including AIDS) and drug addiction. However, these organizations are not producing real results and are simply providing shelter to representatives of the old nomenclature. Real efforts to overcome these problems will continue despite the current discouraging state of affairs.

  5. [Abortion. Spain: the keys to the controversy].

    Science.gov (United States)

    1983-01-01

    For many years, illegal abortion has been denounced in Spain. The estimate of 300,000 abortions annually is widely quoted but poorly founded in fact. Weekend "charters" to London and Amsterdam for women seeking abortions have been commented upon, denounced, and caricatured. The evidence indicates that abortions occur in Spain despite their illegality, just as they occur in every other country and have always occurred. Poor women abort in a poor way, with traditional healers, while rich women abort in a rich way, with physicians. "Charters" are the solution of the middle class. Proposed legislation in Spain would permit abortion on 3 grounds: rape, fetal malformation, and risk to the woman's life if the pregnancy continued. Excesses have been committed both by those opposing abortion and by those struggling for liberalization of laws. Defenders of abortion, such as radical feminists, appear to forget that abortion is a medical procedure with possible dangerous psychophysical consequences, and that preventive measures such as sex education and diffusion of contraception or social measures such as assistance for unwed mothers and their children would be preferrable to abortion. There is the question of whether medical personnel should be excused from assisting in abortions on grounds of conscience and whether those who do assist in abortions automatically become "progressive" by doing so. The staunchest defenders of fetal life are not moved to contribute anything beyond words to improvement of the plight of the many millions of already born who live in miserable conditions of hunger and want. Abortion is a violent act against the fetus and the pregnant woman. Its criminalization is a violent act against the woman and a social intrusion into matters better left to personal ethics. The government which proposes abortion on a few grounds fails to initiate a program to promote life through social protection of single mothers and their children or of families in general

    2011-06-01

    Misoprostol was used by women across Mexico to induce abortion even before 2007, when first-trimester abortion was legalized in Mexico City. Pharmacy vendors' misoprostol recommendation practices across subregions of Mexico after abortion legalization warrant examination. Overall, 192 pharmacies in four regions of Mexico were randomly selected and visited by simulated clients presenting three scenarios (a young woman, an adult woman and a male partner). Bivariate and multivariate analyses were used to explore associations between pharmacy, vendor and client characteristics and drug access. In 558 encounters with simulated clients, 78% of vendors provided information about misoprostol-18% recommended it spontaneously and 60% recommended it only after the client asked specifically for the drug. Fifteen percent of vendors recommended a potentially effective misoprostol dosing regimen. Mexico City-based pharmacies and those in the Central region were significantly less likely than those in the North region to require a prescription to sell misoprostol (odds ratios, 0.2 and 0.3, respectively). Independent pharmacies and those from low-?income areas were significantly more likely to sell misoprostol by the pill than chain pharmacies and those in medium-income areas (3.2 and 2.7, respectively). Access to misoprostol is influenced by neighborhood socioeconomic level, pharmacy location and pharmacy type. The frequently inaccurate and incomplete information provided to clients about using misoprostol for abortion suggests the need to improve pharmacy vendor training in medication abortion options and to develop ways to directly inform women about misoprostol use.

    2015-05-01

    Although unsafe abortion continues to be a leading cause of maternal mortality in many countries in Asia, the right to safe abortion remains highly stigmatized across the region. The Asia Safe Abortion Partnership, a regional network advocating for safe abortion, produced an animated short film entitled From Unwanted Pregnancy to Safe Abortion to show in conferences, schools and meetings in order to share knowledge about the barriers to safe abortion in Asia and to facilitate conversations on the right to safe abortion. This paper describes the making of this film, its objectives, content, dissemination and how it has been used. Our experience highlights the advantages of using animated films in addressing highly politicized and sensitive issues like abortion. Animation helped to create powerful advocacy material that does not homogenize the experiences of women across a diverse region, and at the same time emphasize the need for joint activities that express solidarity.

    The feasibility of using high energy ionizing radiation for the sterilization of hydrocortisone acetate was investigated. Hydrocortisone acetate in the form of powder was exposed to different dose levels of gamma radiation using a Cobalt-60 source. The irradiated samples were examined by various physico-chemical techniques in order to detect possible radiolysis products. It was of interest to know if one could insure sterility and retain biological properties of the drug by suitable choice of radiation dose. The results showed that a 10 KGy radiation dose causes no change in the physico-chemical properties of the drug and is sufficient to obtain contaminant-free product

    KEY MESSAGE: oxa CMS is a new cytoplasmic male sterility type in Brassica juncea. oxa CMS is a cytoplasmic male sterility (CMS) line that has been widely used in the production and cultivation of stem mustard in the southwestern China. In this study, different CMS-type specific mitochondrial markers were used to confirm that oxa CMS is distinct from the pol CMS, ogu CMS, nap CMS, hau CMS, tour CMS, Moricandia arvensis CMS, orf220-type CMS, etc., that have been previously reported in Brassica crops. Pollen grains of the oxa CMS line are sterile with a self-fertility rate of almost 0% and the sterility strain rate and sterility degree of oxa CMS is 100% due to a specific flower structure and flowering habit. Scanning electron microscopy revealed that most pollen grains in mature anthers of the oxa CMS line are empty, flat and deflated. Semi-thin section further showed that the abortive stage of anther development in oxa CMS is initiated at the late uninucleate stage. Abnormally vacuolated microspores caused male sterility in the oxa CMS line. This cytological study combined with marker-assisted selection showed that oxa CMS is a novel CMS type in stem mustard (Brassica juncea). Interestingly, the abortive stage of oxa CMS is later than those in other CMS types reported in Brassica crops, and there is no negative effect on the oxa CMS line growth period. This study demonstrated that this novel oxa CMS has a unique flower structure with sterile pollen grains at the late uninucleate stage. Our results may help to uncover the mechanism of oxa CMS in Brassica juncea.

  16. Prolonged grieving after abortion: a descriptive study.

    Science.gov (United States)

    Brown, D; Elkins, T E; Larson, D B

    1993-01-01

    Although flawed by methodological problems, the research literature tends to provide support for the assumption that induced abortion in the 1st trimester is not accompanied by enduring negative psychological sequelae. In cases where such sequelae are reported, the morbidity is attributed to a pre-existing psychiatric condition or circumstances precipitating the choice of abortion. However, detailed descriptive letters from 45 women prepared in response to a request by a pastor of an upper-middle-class Protestant congregation in Florida indicate that prolonged grieving after abortion may be more widespread phenomenon than previously believed. Letter writers ranged in age from 25-60 years; 75% were unmarried at the time of the procedure and 29% aborted before the legalization of abortion in the US. The most frequently cited long-term sequela, especially among those who felt coerced to abort, was a continued feeling of guilt. Fantasies about the aborted fetus was the next most frequently mentioned experience. Half of the letter writers referred to their abortions, as "murder" and 44% voiced regret about their decision to abort. Other long-term effects included depression (44%), feelings of loss (31%), shame (27%), and phobic responses to infants (13%). For 42% of these women, the adverse psychological effects of abortion endured over 10 years. Since letter-writers came from a self-selected population group with a known bias against abortion and only negative experiences were solicited, these experiences must be regarded as subjectives and anecdotal. However, they draw attention to the need for methodologically sound studies of a possible prolonged grief syndrome among a small percentage of women who have abortions, especially when coercion is involved.

  17. Abortion checks at German-Dutch border.

    Von Baross, J

    1991-05-01

    The commentary on West German abortion law, particularly in illegal abortion in the Netherlands, finds the law restrictive and in violation of the dignity and rights of women. The Max-Planck Institute in 1990 published a study that found that a main point of prosecution between 1976 and 1986, as reported by Der Spiegal, was in border crossings from the Netherlands. It is estimated that 10,000 annually have abortions abroad, and 6,000 to 7,000 in the Netherlands. The procedure was for an official to stop a young person and query about drugs; later the woman would admit to an abortion, and be forced into a medical examination. The German Penal Code Section 218 stipulates abortion only for certain reasons testified to by a doctor other than the one performing the abortion. Counseling on available social assistance must be completed 3 days prior to the abortion. Many counseling offices are church related and opposed to abortions. Many doctors refuse legally to certify, and access to abortion is limited. The required hospital stay is 3-4 nights with no day care facilities. Penal Code Section 5 No. 9 allows prosecution for uncounseled illegal abortion. Abortion law reform is anticipated by the end of 1992 in the Bundestag due to the Treaty or the Unification of Germany. The Treaty states that the rights of the unborn child must be protected and that pregnant women relieve their distress in a way compatible with the Constitution, but improved over legal regulations from either West or East Germany, which permits abortion on request within 12 weeks of conception without counseling. It is hoped that the law will be liberalized and Penal Code Section 5 No. 9 will be abolished.

    Full Text Available Background: Population measures of sterility are traditionally constructed for women, despite fertility and sterility being conditions of the couple. Estimates of male sterility provide insight into population-level sterility, and complement estimates based solely on women. Objective: This study seeks to estimate male sterility for the Gwembe Tonga of Zambia using male birth histories collected by the Gwembe Tonga Research Project from 1957 to 1995, while providing context by estimating female sterility for the Gwembe Tonga, as well as female sterility in all of Zambia, from Zambian DHS data (1992, 1997, 2001-02, and 2007. Methods: Sterility is measured using the Larson-Menken subsequently infertile indicator. Estimates are produced using discrete time event history analysis. Results: The odds of sterility were higher for women than men, though women's odds of sterility were only 1.5 times that of men's in the middle reproductive years. The odds of sterility increased steadily with age for both men and women, and across all datasets. However, women's sterility increased much more sharply with age than men's did, and women's odds of sterility were higher than men's at all reproductive ages.

    Clandestine induced abortions are a public health problem in many developing countries where access to abortion services is legally restricted. We estimated the prevalence and incidence of, and risk factors for, clandestine induced abortions in a Latin American country. We conducted a large population-based survey of women aged 18-29 years in 20 cities in Peru. We asked questions about their history of spontaneous and induced abortions, using techniques to encourage disclosure. Of 8242 eligible women, 7992 (97.0%) agreed to participate. The prevalence of reported induced abortions was 11.6% (95% confidence interval [CI] 10.9%-12.4%) among the 7962 women who participated in the survey. It was 13.6% (95% CI 12.8%-14.5%) among the 6559 women who reported having been sexually active. The annual incidence of induced abortion was 3.1% (95% CI 2.9%-3.3%) among the women who had ever been sexually active. In the multivariable analysis, risk factors for induced abortion were higher age at the time of the survey (odds ratio [OR] 1.11, 95% CI 1.07-1.15), lower age at first sexual intercourse (OR 0.87, 95% CI 0.84-0.91), geographic region (highlands: OR 1.56, 95% CI 1.23-1.97; jungle: OR 1.81, 95% CI 1.41-2.31 [v. coastal region]), having children (OR 0.82, 95% CI 0.68-0.98), having more than 1 sexual partner in lifetime (2 partners: OR 1.61, 95% CI 1.23-2.09; > or = 3 partners: OR 2.79, 95% CI 2.12-3.67), and having 1 or more sexual partners in the year before the survey (1 partner: OR 1.36, 95% CI 1.01-1.72; > or = 2 partners: OR 1.54, 95% CI 1.14-2.02). Overall, 49.0% (95% CI 47.6%-50.3%) of the women who reported being currently sexually active were not using contraception. The incidence of clandestine, potentially unsafe induced abortion in Peru is as high as or higher than the rates in many countries where induced abortion is legal and safe. The provision of contraception and safer-sex education to those who require it needs to be greatly improved and could potentially

    There has been continued interest in the extent to which women have positive and negative reactions to abortion. To document emotional reactions to abortion, and to examine the links between reactions to abortion and subsequent mental health outcomes. Data were gathered on the pregnancy and mental health history of a birth cohort of over 500 women studied to the age of 30. Abortion was associated with high rates of both positive and negative emotional reactions; however, nearly 90% of respondents believed that the abortion was the right decision. Analyses showed that the number of negative responses to the abortion was associated with increased levels of subsequent mental health disorders (Pabortion and reporting negative reactions had rates of mental health disorders that were approximately 1.4-1.8 times higher than those not having an abortion. Abortion was associated with both positive and negative emotional reactions. The extent of negative emotional reactions appeared to modify the links between abortion and subsequent mental health problems.

    To determine the long-range psychological effects of therapeutic abortion, 50 women (aged from 13-44 years), who were granted abortions between 1967 and 1968 Because of possible impairment of mental and/or physical health, were analyzed by use of demographic questionnaires, psychological tests, and interviews. Testing revealed that 44 women had psychiatric problems at time of abortion. 43 patients were followed for 3-6 months. The follow-up interviews revealed that 29 patients reacted positively after abortion, 10 reported no significant change and 4 reacted negatively. 37 would definitely repeat the abortion. Women under 21 years of age felt substantially more ambivalent and guilty than older patients. A study of 36 paired pre- and post-abortion profiles showed that 15 initially abnormal tests had become normal. There was a significant increase in contraceptive use among the patients after the abortion, but 4 again became pregnant and 8 were apparently without consistent contraception. It is concluded that the abortions were therapeutic, but physicians are encouraged to be aware of psychological problems in abortion cases. Strong psychological and contraceptive counselling should be exercised.

    This study analyzes the involvement of men in abortion in Vietnam, where induced abortion is legal and abortion rates are among the highest in the world. Twenty men were interviewed in 1996 about the role they played in their wives' abortions and about their feelings and ethical views concerning the procedure. The results showed that both husbands and wives considered the husband to be the main decisionmaker regarding family size, which included the decision to have an abortion, but that, in fact, some women had undergone an abortion without consulting their husbands in advance. Parents and in-laws were usually not consulted; the couples thought they might object to the decision on moral grounds. Respondents' ethical perspectives on abortion are discussed. When faced with an unwanted pregnancy, the husbands adopted an ethics of care and responsibility toward family and children, although some felt that abortion was immoral. The study highlights the importance of understanding husbands' perspectives on their responsibilities and rights in reproductive decisionmaking and their ethical and other concerns related to abortion.

  3. Two steps back: Poland's new abortion law.

    After the fall of Communism in Poland, the Catholic church exerted pressure to increase its influence in public life. One way in which this pressure has manifested itself has been in the passing of a restrictive abortion bill which was signed into law on February 15, 1993. Abortion had been legalized in Poland in 1956 and was used as a means of birth control because of a lack of availability and use of contraceptives. The number of abortions performed was variously reported as 60,000 - 300,000/year. In 1990, the Ministry of Health imposed restrictions on abortions at publicly funded hospitals, and 3 deaths were reported from self-induced abortions. In 1 year (1989-90), the number of induced abortions at 1 hospital dropped from 71 to 19, while the number of self-induced abortions increased from 48 to 85. Further restrictions were introduced in May 1992 as part of the "Ethical Code for Physicians," which allows abortions only in cases where the mother's life or health is in danger or in cases or rape. This code brought abortions to a halt at publicly funded hospitals and doubled or even tripled the cost of private abortions. Women have been refused abortions in tragic and life=threatening situations since the code was adopted. When an outright anti family planning bill was drafted in November 1992, the Polish citizenry collected 1,300,000 signatures to force a referendum. The referendum was not held, but the bill was defeated. The amended bill which passed allows abortions in publicly funded hospitals only when the mother's life or health is in danger and in cases of rape, incest, or incurable deformity of the fetus. The implications of this law remain unclear, since its language is strange and vague. The reproductive rights of Polish women face a further threat because the Catholic church is working to limit the availability of contraceptive methods which they deem to be "early abortives." On the other side of the issue, the Federation for Women and Planned

    "This paper uses econometric multiple regression techniques in order to analyze the socioeconomic factors affecting the demand for abortion for the year 1985. A cross-section of the 50 [U.S.] states and Washington D.C. is examined and a household choice theoretical framework is utilized. The results suggest that average price of abortion, disposable personal per capita income, percentage of single women, whether abortions are state funded, unemployment rate, divorce rate, and if the state is located in the far West, are statistically significant factors in the determination of the demand for abortion." excerpt

    Unsafe abortion causes 13% of maternal deaths worldwide. Safe abortion can only be offered under conditions where legislation has been passed for legal termination of unwanted pregnancy. Where such legislation exists, accessibility of safe abortion depends on the attitudes of doctors and other healthcare workers to induced abortion. Medical students as future doctors may have attitudes to abortion that will affect the provision of safe abortion. Little is known about the attitudes of South African medical students to abortion. To assess sexual practices and attitudes of medical students to induced abortion and to determine some of the factors that may influence these attitudes. A cross-sectional analytic study involving the self-administration of an anonymous questionnaire. The questionnaire was administered to medical students at a small, but growing, medical school situated in rural South Africa. Demographic data, sexual practices and attitudes to induced abortion. Two hundred and forty seven out of 300 (82.3%) medical students responded. Their mean age was 21.81 +/- 3.36 (SD) years, and 78.8% were Christians, 17.1% Hindus and 2.6% Muslims. Although 95% of the respondents were single, 68.6% were already sexually experienced, and their mean age at coitarche was 17.24+/-3.14 (SD) years. Although overall 61.2% of the respondents felt abortion is murder either at conception or later, the majority (87.2%) would perform or refer a woman for abortion under certain circumstances. These circumstances, in descending order of frequency, include: threat to mother's life (74.1%), in case of rape (62.3%), the baby is severely malformed (59.5%), threat to mother's mental health (53.8%) and parental incompetence (21.0%). Only 12.5% of respondents would perform or refer for abortion on demand, 12.8% would neither perform nor refer for abortion under any circumstances. Religious affiliation and service attendance significantly influenced some of these attitudes and beliefs

    2017-07-01

    On the fourth day of his presidency, Donald Trump reinstated and greatly expanded the "Mexico City policy," which imposes antiabortion restrictions on U.S. foreign health aid. In general, the policy has prohibited U.S. funding of any family-planning groups that use even non-U.S. funds to perform abortions; prohibited aid recipients from lobbying (again, even with non-U.S. money) for liberalization of abortion laws; prohibited nongovernment organizations from creating educational materials on abortion as a family-planning method; and prohibited health workers from referring patients for legal abortions in any cases other than rape, incest, or to save the life of the mother. The policy's prohibition on giving aid to any organization that performs abortions is aimed at limiting alleged indirect funding of abortions. The argument is that if U.S. money is used to fund nonabortion programs of an abortion-providing NGO, then the NGO can simply shift the money thus saved into its abortion budget. Outside the context of abortion, we do not reason this way. And the policy's remaining three prohibitions are deeply troubling. © 2017 The Hastings Center.

    Abortion traditionally means, "to miscarry" and is still known as a problem which societies has been trying to reduce its rate by using legal means. Despite the pregnant women and fetuses have being historically supported; abortion was firstly criminalized in 1926 in Iran, 20 years after establishment of modern legal system. During next 53 years this situation changed dramatically, so in 1979, the time of Islamic Revolution, aborting fetuses before 12 weeks and therapeutic abortion (TA) during all the pregnancy length was legitimate, based on regulations that used medical justification. After 1979 the situation changed into a totally conservative and restrictive approach and new Islamic concepts as "Blood Money" and "Ensoulment" entered the legal debates around abortion. During the next 33 years, again a trend of decriminalization for the act of abortion has been continuing. Reduction of punishments and omitting retaliation for criminal abortions, recognizing fetal and maternal medical indications including some immunologic problems as legitimate reasons for aborting fetuses before 4 months and omitting the fathers' consent as a necessary condition for TA are among these changes. The start point for this decriminalization process was public and professional need, which was responded by religious government, firstly by issuing juristic rulings (Fatwas) as a non-official way, followed by ratification of "Therapeutic Abortion Act" (TAA) and other regulations as an official pathway. Here, we have reviewed this trend of decriminalization, the role of public and professional request in initiating such process and the rule-based language of TAA.

    Unbunched beam is a potentially serious issue in the LHC as it may quench the superconducting magnets during a beam abort. Unbunched particles, either not captured by the RF system at injection or leaking out of the RF bucket, will be removed by using the existing damper kickers to excite resonantly the particles in the abort gap. Following beam simulations, a strategy for cleaning the abort gap at different energies was proposed. The plans for the commissioning of the beam abort gap cleaning are described and first results from the beam commissioning are presented.

    To explore Swedish women's experiences of clinical abortion care in relation to their need for existential support. Individual in-depth interviews with 24 women with previous experience of unwanted pregnancy and abortion. Participants were recruited between 2006 and 2009. Interviews were analysed by latent content analysis. Although the women had similar experiences of the abortion care offered, the needs they expressed differed. Swedish abortion care was described as rational and neutral, with physical issues dominating over existential ones. For some women, the medical procedures triggered existential experiences of life, meaning, and morality. While some women abstained from any form of existential support, others expressed a need to reflect upon the existential aspects and/or to reconcile their decision emotionally. As women's needs for existential support in relation to abortion vary, women can be disappointed with the personnel's ability to respond to their thoughts and feelings related to the abortion. To ensure abortion care personnel meet the physical, psychological and existential needs of each patient, better resources and new lines of education are needed to ensure abortion personnel are equipped to deal with the existential aspects of abortion care.

    Abortion stigma may cause psychological distress in women who are considering having an abortion or have had one. This phenomenon has been relatively underexplored in low-income women, who may already be at an increased risk for poor abortion-related outcomes because of difficulties accessing timely and safe abortion services. A qualitative study conducted between 2010 and 2013 used semistructured interviews to explore pregnancy intentions among low-income women recruited from six reproductive health clinics in Western Pennsylvania. Transcripts from interviews with 19 participants who were planning to terminate a pregnancy or had had an abortion in the last two weeks were examined through content analysis to identify the range of attitudes they encountered that could contribute to or reflect abortion stigma, the sources of these attitudes and women's responses to them. Women commonly reported that partners, family members and they themselves held antiabortion attitudes. Such attitudes communicated that abortion is morally reprehensible, a rejection of motherhood, rare and thus potentially deviant, detrimental to future fertility and an irresponsible choice. Women reacted to external and internal negative attitudes by distinguishing themselves from other women who obtain abortions, experiencing negative emotions, and concealing or delaying their abortions. Women's reactions to antiabortion attitudes may perpetuate abortion stigma. Further research is needed to inform interventions to address abortion stigma and improve women's abortion experiences.

  17. Tapetal-Delayed Programmed Cell Death (PCD and Oxidative Stress-Induced Male Sterility of Aegilops uniaristata Cytoplasm in Wheat

    Full Text Available Cytoplasmic male sterility (CMS plays a crucial role in the utilization of hybrid vigor. Pollen development is often accompanied by oxidative metabolism responses and tapetal programmed cell death (PCD, and deficiency in these processes could lead to male sterility. Aegilops uniaristata cytoplasmic male sterility (Mu-CMS wheat is a novel male-sterile line in wheat, which possess important potential in hybrid wheat breeding. However, its CMS mechanisms remain poorly understood. In our study, U87B1-706A, with the Aegilops uniaristata cytoplasm, and the maintainer line 706B were used to explore the abortive reason. Compared with 706B, histological analysis and PCD detection of the anther demonstrated that U87B1-706A appeared as delayed tapetal PCD as well as a disorganized organelle phenotype in the early uninucleate stage. Subsequently, a shrunken microspore and disordered exine structure were exhibited in the late uninucleate stage. While the activities of antioxidase increased markedly, the nonenzymatic antioxidant contents declined obviously following overacummulation of reactive oxygen species (ROS during pollen development in U87B1-706A. Real-time quantitative PCR testified that the transcript levels of the superoxide dismutase (SOD, catalase (CAT, and ascorbate peroxidase (APX genes, encoding pivotal antioxidant enzymes, were up-regulated in early pollen development. Therefore, we deduce excess ROS as a signal may be related to the increased expression levels of enzyme genes, thereby breaking the antioxidative system balance, resulting in delayed tapetal PCD initiation, which finally led to pollen abortion and male sterility in U87B1-706A. These results provide evidence to further explore the mechanisms of abortive pollen in CMS wheat.

  18. Evidence supporting broader access to safe legal abortion.

    Science.gov (United States)

    Faúndes, Anibal; Shah, Iqbal H

    2015-10-01

    Unsafe abortion continues to be a major cause of maternal death; it accounts for 14.5% of all maternal deaths globally and almost all of these deaths occur in countries with restrictive abortion laws. A strong body of accumulated evidence shows that the simple means to drastically reduce unsafe abortion-related maternal deaths and morbidity is to make abortion legal and institutional termination of pregnancy broadly accessible. Despite this evidence, abortion is denied even when the legal condition for abortion is met. The present article aims to contribute to a better understanding that one can be in favor of greater access to safe abortion services, while at the same time not be "in favor of abortion," by reviewing the evidence that indicates that criminalization of abortion only increases mortality and morbidity without decreasing the incidence of induced abortion, and that decriminalization rapidly reduces abortion-related mortality and does not increase abortion rates.

    2015-01-01

    MINOS, Main Injector Neutrino Oscillation Search, is a long-baseline neutrino oscillation experiment in the NuMI muon neutrino beam at the Fermi National Accelerator Laboratory in Batavia, IL. It consists of two detectors, a near detector positioned 1 km from the source of the beam and a far detector 734 km away in Minnesota. MINOS is primarily designed to observe muon neutrino disappearance resulting from three flavor oscillations. The Standard Model of Particle Physics predicts that neutrinos oscillate between three active flavors as they propagate through space. This means that a muon-type neutrino has a certain probability to later interact as a different type of neutrino. In the standard picture, the neutrino oscillation probabilities depend only on three neutrino flavors and two mass splittings, Δm 2 . An anomaly was observed by the LSND and MiniBooNE experiments that suggests the existence of a fourth, sterile neutrino flavor that does not interact through any of the known Standard Model interactions. Oscillations into a theoretical sterile flavor may be observed by a deficit in neutral current interactions in the MINOS detectors. A distortion in the charged current energy spectrum might also be visible if oscillations into the sterile flavor are driven by a large mass-squared difference, Δm s 2 ~ 1 eV 2 . The results of the 2013 sterile neutrino search are presented here.

    A new dimension has been added to the use of radiation in the medical field with the introduction of radiation as a sterilizing agent. Its use in diagnosis through radioactive tracers or X-rays and in therapy administered with the most sophisticated of electrical machines or radioisotope units, is familiar in the hospital world, being well established therein. In contrast, the application of radiation sterilization is in industry where the installation of large radiation sources is already commonplace in many countries. The beginnings in the early 1950's centered on the Van de Graaff machine and linear accelerators and the pioneering efforts of Ethicon Inc. here in the United States must be recognized. However, although sterilization with electron beams is still current practice in a number of plants, the use of gamma rays from cobalt-60 is preferred. The first steps in this direction were taken by the U.K.A.E.A. which, in common with similar organizations elsewhere, was attempting to exploit the tremendous potential for cobalt-60 production arising through the rapid construction of nuclear reactors. The first full-scale commercial gamma plant was commissioned in the U.K. in 1960. It reached a loading of 500,000 curies before its demolition after twelve years of operation. The process gained rapid acceptance within industry and approval by health authorities because it provided a ''cold'' sterilization method combining the property of lethal effect with penetration. Its immediate impact occurred in the introduction of disposable products making it possible, for example, to use heat-labile plastics and new packaging materials and package designs. Certainly, the technique has proved complementary to sterilization methods based on heat and to the use of chemical agents, in particular ethylene oxide gas

    Measurements of neutrino oscillations at short baselines contain an intriguing set of experimental anomalies that may be suggestive of new physics such as the existence of sterile neutrinos. This three-part thesis presents research directed towards understanding these anomalies and searching for sterile neutrino oscillations. Part I contains a theoretical discussion of neutrino coherence properties. The open-quantum-system picture of neutrino beams, which allows a rigorous prediction of coherence distances for accelerator neutrinos, is presented. Validity of the standard treatment of active and sterile neutrino oscillations at short baselines is verified, and non-standard coherence loss effects at longer baselines are predicted. Part II concerns liquid argon detector development for the MicroBooNE experiment, which will search for short-baseline oscillations in the Booster Neutrino Beam at Fermilab. Topics include characterization and installation of the MicroBooNE optical system; test-stand measurements of liquid argon optical properties with dissolved impurities; optimization of wavelength-shifting coatings for liquid argon scintillation light detection; testing and deployment of high-voltage surge arrestors to protect TPC field cages; and software development for optical and TPC simulation and reconstruction. Part III presents a search for sterile neutrinos using the IceCube neutrino telescope, which has collected a large sample of atmospheric-neutrino-induced events in the 1-10 TeV energy range. Sterile neutrinos would modify the detected neutrino flux shape via MSW-resonant oscillations. Following a careful treatment of systematic uncertainties in the sample, no evidence for MSW-resonant oscillations is observed, and exclusion limits on 3+1 model parameter space are derived. Under the mixing assumptions made, the 90% confidence level exclusion limit extends to sin 2 2θ 24 ≤ 0.02 at m 2 ~ 0.3 eV 2 , and the LSND and MiniBooNE allowed regions are excluded at

    We investigate the process of reionization in a model in which the dark matter is a warm elementary particle such as a sterile neutrino. We focus on models that are consistent with the dark matter decay interpretation of the recently detected line at 3.5 keV in the X-ray spectra of galaxies and clusters. In warm dark matter models, the primordial spectrum of density perturbations has a cut-off on the scale of dwarf galaxies. Structure formation therefore begins later than in the standard cold dark matter (CDM) model and very few objects form below the cut-off mass scale. To calculate the number of ionizing photons, we use the Durham semi-analytic model of galaxy formation, GALFORM. We find that even the most extreme 7 keV sterile neutrino we consider is able to reionize the Universe early enough to be compatible with the bounds on the epoch of reionization from Planck. This, perhaps surprising, result arises from the rapid build-up of high redshift galaxies in the sterile neutrino models which is also reflected in a faster evolution of their far-UV luminosity function between 10 > z > 7 than in CDM. The dominant sources of ionizing photons are systematically more massive in the sterile neutrino models than in CDM. As a consistency check on the models, we calculate the present-day luminosity function of satellites of Milky Way-like galaxies. When the satellites recently discovered in the Dark Energy Survey are taken into account, strong constraints are placed on viable sterile neutrino models.

    Abortion has been legalized in Nepal since September 2002 by 11th amendment to the Muluki Ain. The present study was conducted in Paropakar Shree Panch Indra Rajya Laxmi Devi Maternity Hospital to assess the magnitude of induced abortion, its causes and the types of complications, in the post legalization phase. Prospective descriptive analyses of the patients who were admitted with history of induced abortion from 16th Dec 2003 to 13th March 2004 was carried out. A total of 305 cases of abortion complications were admitted during the three-month study period, which is 39.7% of the total gynaecological admissions (768). Of these 31 (10.25%) patients had history of induced abortion. Half of the induced abortion cases (52%) were of age group 21-29 yrs and 42% had three or more children. 39% of the cases had history of induced abortion at more than 12 weeks and almost half of the cases (48%) had history of family planning. The most common reason for seeking abortion was too many children (59%) followed by illegitimate pregnancy (16%). Twenty-one patients gave history of abortion being performed by doctors and the most common method used was D and C (75%). 77% of cases presented as incomplete abortion and one case presented with uterine perforation, bowel injury and peritonitis. Twenty patients had evacuation under sedation while five had manual vacuum aspiration (MVA); one patient required laparatomy. In two third of the patients intravenous fluid and antibiotics were used. Four patients required blood transfusion. Abortion complications constitute almost 40% of the total gynaecological admissions. Ten percent of the abortion cases had history of induced abortion. Medical persons, mainly doctors, performed most of the cases of induced abortion and D and C was the most commonly used method. However the patients had faced various types of complications. Untrained provider, resulting in serious life threatening injuries, performed more than a third of the cases of

  9. The Roman Catholic position on abortion.

    1997-01-01

    This article presents the history and grounds of the official position of the Roman Catholic Church that abortion under any circumstances, including abortion to save the life of the mother, should be prohibited. After an introduction that deplores the lack of mercy shown to killers of abortionists while Catholic priests threatened by pro-abortion forces are not offered protection, the article traces the historic development of the Catholic abortion policy and rebuts arguments that abortion was permitted in the early Christian Church. The next section explains Catholic views on the personhood of a conceptus and refutes the contentions of Joseph Donceel that early abortion should be permitted because of uncertainty about the nature of the conceptus and the possibility of delayed animation. The fourth section of the paper debates the points raised by Susan Teft Nicholson who maintains that the Catholic position regarding abortion rests on the Church's animosity towards sexual pleasure. The paper goes on to criticize Nicholson's claims that the Roman Catholic position on abortion is inconsistent with the Church's own understanding of the Principle of Double Effect because the Church fails to allow abortion in many cases where it would be permissible under the Principle. Section 6 describes the underlying motive of the Roman Catholic Church's abortion position as an attempt to protect the innocent fetus from deliberate death and to justify the Church's application of protection from deliberate killing to those who are innocent of aggressive action. This discussion is followed by a justification of the Church's prohibition of abortion in cases of aggression, such as the aggression ascribed to a fetus when a pregnancy imperials the life of a mother. It is concluded that the US will likely legalize suicide and mercy killing as it has the killing of innocent fetuses who are probably ensouled with personhood and are not formal aggressors.

  10. Irish women who seek abortions in England.

    1992-01-01

    In 1991, 4158 women from Ireland and 1766 from Northern Ireland traveled to England for abortions. This situation has been ignored by Irish authorities. The 1992 case of the 14-year old seeking an abortion in England finally caught legal attention. This study attempts to help define who these abortion seekers are. Questionnaires from 200 Irish abortion seeking women attending private Marie Stopes clinics in London and the British Pregnancy Advisory Services clinic in Liverpool between September 1988 and December 1990 were analyzed. Findings pertain to demographic characteristics, characteristics of first intercourse, family discussion of sexual activity, and contraceptive use. From this limited sample, it appears that Irish women are sexually reserved and without access to modern methods of birth control and abortion. Sex is associated with shame and guilt. 23% had intercourse before the age of 18 years and 42% after the age of 20. 76% were single and 16% were currently married. 95% were Catholic; 33% had been to church the preceding Sunday and 68% within the past month. Basic information about menstruation is also limited and procedures such as dilatation and curettage may be performed selectively. 28% of married women were uninformed about menstruation prior to its onset. Only 24% had been using birth control around the time of pregnancy. The reason for nonuse was frequently the unexpectedness of intercourse. 62% of adults and 66% of women believe in legalizing abortion in Ireland. British groups have tried to break through the abortion information ban by sending telephone numbers of abortion clinics to Irish firms for distribution to employees. On November 25, 1992, in the general election, there was approval of constitutional amendments guaranteeing the right to travel for abortions and to receive information on abortion access. The amendment to allow abortion to save the life of the mother was not accepted.

  11. Clandestine abortions are not necessarily illegal.

    1991-01-01

    It is common to find the term illegal abortion misused. Often times this misuse is perpetrated by antiabortion advocates who wish to reinforce negative stereotypes and thus apply pressure on doctors to refrain from performing abortions. Until a practitioner is prosecuted and convicted of performing an abortion contrary to the law, the procedure should not be referred to as illegal. Instead the legally neutral term, abortion, should be used instead. This would better serve the interests of women's reproductive health. There is no legal system that makes abortion illegal in all circumstances. For example, abortion is often legal if the life of the mother in danger. This includes a perception on behalf of the practitioner that the women may be suicidal or attempt to terminate the pregnancy by herself. A practitioner performing an abortion in such circumstances is not doing so illegally. The use of the term illegal abortion ignores the fact that in criminal law one is presumed innocent until proven guilty. A prosecutor must prove 1st that an intervention was performed and 2nd that a criminal intent accompanied the intervention. It is this 2nd criterion that is often the hardest to prove, since the practitioner must only testify that the intervention was indicated by legally allowed circumstances to be innocent. The prosecutor must show bad faith in order to gain a justified conviction. Even abortion by unqualified practitioners may not be illegal if doctors refuse to perform the intervention because it is still indicated. Accurate description of abortions would clarify situations in which abortion can be legally provided.

    Full Text Available The debates and feminist actions in favor of the legalization of abortion in Brazil were characterized by progresses and regressions, and above all by countless political negotiations. From the omission of the word “abortion”, in the mid-seventies, to the political choice of decriminalization and application of the cases foreseen by law, Brazilian feminism has been marked by the choice of negotiation. The article concludes that these negotiations have succeeded politically but failed to reach society and heighten public awareness at a large scale.

    To evaluate the associations between birth order, maternal abortion and mode of delivery and childhood acute leukemia risk. Multiple electronic databases were searched to identify relevant studies up to March 2013 using the search terms "childhood leukemia", "acute lymphoblastic leukemia", "acute myeloid leukemia","birth order", "abortion", "miscarriage", "cesarean", "birth characteristics" and "prenatal risk factor". Data from cohort and case-control studies were analyzed using the Stata software. Twenty-three studies were included in this meta-analysis according to the selection criteria. No significant associations were identified for birth order and mode of delivery (birth order = 2: OR = 0.97, 95%CI: 0.89-1.05; birth order = 3: OR = 1.00, 95%CI: 0.91-1.11; birth order ≥ 4: OR = 1.02, 95%CI: 0.87-1.20; mode of delivery: OR = 1.05, 95%CI: 0.96-1.15). However, there was a significant association between maternal abortion and childhood acute leukemia risk (spontaneous abortion: OR = 1.21, 95%CI: 1.05-1.41; induced abortion: OR = 1.23, 95%CI: 1.07-1.43). Furthermore, the stratified analysis by disease subtypes showed that spontaneous and induced abortions were significantly associated with the risks of childhood acute myeloid leukemia (OR = 1.71, 95%CI: 1.09-2.70) and acute lymphoblastic leukemia (OR = 1.23, 95%CI: 1.05-1.42), respectively. This meta-analysis revealed that maternal abortion might contribute to the childhood acute leukemia risk.

    The risk of spontaneous abortion in 1-12 week gestation term among Kiev region women with desired pregnancy is considered. If cumulative dose of total irradiation among Kiev region women was more than 5.0 mSv, spontaneous abortion risk increased. Mother's age more than 34, smoking, chronic infections and sterility treatment in anamnesis also increased spontaneous abortion risk. The material well being does not influence spontaneous abortion risk among women

  17. Framing a 'social problem': Emotion in anti-abortion activists' depiction of the abortion debate.

    Social psychological research on activism typically focuses on individuals' social identifications. We complement such research through exploring how activists frame an issue as a social problem. Specifically, we explore anti-abortion activists' representation of abortion and the abortion debate's protagonists so as to recruit support for the anti-abortion cause. Using interview data obtained with UK-based anti-abortion activists (N = 15), we consider how activists characterized women having abortions, pro-abortion campaigners, and anti-abortion campaigners. In particular, we consider the varied ways in which emotion featured in the representation of these social actors. Emotion featured in different ways. Sometimes, it was depicted as constituting embodied testament to the nature of reality. Sometimes, it was depicted as blocking the rational appraisal of reality. Our analysis considers how such varied meanings of emotion shaped the characterization of abortion and the abortion debate's protagonists such that anti-abortion activists were construed as speaking for women and their interests. We discuss how our analysis of the framing of issues as social problems complements and extends social psychological analyses of activism. © 2018 The British Psychological Society.

  18. Mitochondrial Dysfunction Causes Oxidative Stress and Tapetal Apoptosis in Chemical Hybridization Reagent-Induced Male Sterility in Wheat

    Full Text Available Male sterility in plants has been strongly linked to mitochondrial dysfunction. Chemical hybridization agent (CHA-induced male sterility is an important tool in crop heterosis. Therefore, it is important to better understand the relationship between mitochondria and CHA-induced male sterility in wheat. This study reports on the impairment of mitochondrial function duo to CHA-SQ-1, which occurs by decreasing cytochrome oxidase and adenosine triphosphate synthase protein levels and theirs activities, respiratory rate, and in turn results in the inhibition of the mitochondrial electron transport chain (ETC, excessive production of reactive oxygen species (ROS and disruption of the alternative oxidase pathway. Subsequently, excessive ROS combined with MnSOD defects results in damage to the mitochondrial membrane, followed by ROS release into the cytoplasm. The microspores underwent severe oxidative stress during pollen development. Furthermore, chronic oxidative stress, together with the overexpression of type II metacaspase, triggered premature tapetal apoptosis, which resulted in pollen abortion. Accordingly, we propose a metabolic pathway for mitochondrial-mediated male sterility in wheat, which provides information on the molecular events underlying CHA-SQ-1-induced abortion of anthers and may serve as an additional guide to the practical application of hybrid breeding.

    The authors evaluated empirical research addressing the relationship between induced abortion and women's mental health. Two issues were addressed: (a) the relative risks associated with abortion compared with the risks associated with its alternatives and (b) sources of variability in women's responses following abortion. This article reflects and updates the report of the American Psychological Association Task Force on Mental Health and Abortion (2008). Major methodological problems pervaded most of the research reviewed. The most rigorous studies indicated that within the United States, the relative risk of mental health problems among adult women who have a single, legal, first-trimester abortion of an unwanted pregnancy is no greater than the risk among women who deliver an unwanted pregnancy. Evidence did not support the claim that observed associations between abortion and mental health problems are caused by abortion per se as opposed to other preexisting and co-occurring risk factors. Most adult women who terminate a pregnancy do not experience mental health problems. Some women do, however. It is important that women's varied experiences of abortion be recognized, validated, and understood. 2009 APA.

  20. Comment: unethical ethics investment boycotts and abortion.

    Ethical investment funds have traditionally boycotted the arms industry, companies known to pollute the environment, and those involved in animal research. However, recent newspaper reports suggest that some investment funds plan to also boycott hospitals and pharmaceutical companies involved in abortion-related activities. Ethical Financial, anti-abortion independent financial advisors, are encouraging a boycott of investment in private hospitals and manufacturers of equipment involved in abortions, and pharmaceutical firms which produce postcoital contraception or conduct embryo research. Ethical Financial claims that Family Assurance has agreed to invest along anti-abortion lines, Aberdeen Investment is already boycotting companies linked to abortion, and Hendersons ethical fund plans to follow suit. There is speculation that Standard Life, the largest mutual insurer in Europe, will also refuse to invest in abortion-related concerns when it launches its ethical fund in the spring. Managers of ethical funds should, however, understand that, contrary to the claims of the anti-choice lobby, there is extensive public support for legal abortion, emergency contraception, and embryo research. Individuals and institutions which contribute to the development of reproductive health care services are working to alleviate the distress of unwanted pregnancy and infertility, laudable humanitarian goals which should be encouraged. Those who try to restrict the development of abortion methods and services simply show contempt for women, treating them as people devoid of conscience who are incapable of making moral choices.

  1. Opposition to legal abortion: challenges and questions.

    1993-01-01

    An analysis of the Roman Catholic Church's arguments against abortion rights suggests that its opposition is grounded more in outmoded views regarding women's roles than in concern for protecting fetal life. The 1st argument raised by Catholics and other anti-abortion forces is that abortion represents the unjustifiable destruction of a human life. A 2nd argument focuses on the status of the fetus as a person from the moment of conception, making abortion murder. A 3rd equates the fetus's potential for personhood with the pregnant woman's actual personhood. Despite the vehement sentiments expressed by Catholic leaders against abortion, the majority of Catholics support legal abortion. The assignment of personhood status to the fetus is contraindicated by actual practice in the Church, where aborted or miscarried products of early pregnancy are not baptized. Also, the Church does not forbid the taking of human life in war or to preserve political freedom. Finally, in countries such as Poland where abortion has been made illegal through religious pressure, there have been drastic cuts in health care and child care programs.

    Complications following spontaneous or induced abortion are a major cause of maternal morbidity. To manage these complications, post-abortion care (PAC) services should be readily available and easy to access. Standard PAC treatment includes surgical interventions that are highly effective but require surgical providers and medical centers that have the necessary space and equipment. Misoprostol has been shown to be an effective alternative to surgical evacuation and can be offered by lower level clinicians. This study sought to assess whether 400 mcg sublingual misoprostol could effectively evacuate the uterus after incomplete abortion and to confirm its applicability for use at lower level settings. All women presenting with incomplete abortion at one of three hospitals in Vietnam were enrolled. Providers were not asked to record if the abortion was spontaneous or induced. It is likely that all were spontaneous given the legal status and easy access to abortion services in Vietnam. Participants were given 400 mcg sublingual misoprostol and instructed to hold the pills under their tongue for 30 minutes and then swallow any remaining fragments. They were then asked to return one week later to confirm their clinical status. Study clinicians were instructed to confirm a complete expulsion clinically. All women were asked to complete a questionnaire regarding satisfaction with the treatment. Three hundred and two women were enrolled between September 2009 and May 2010. Almost all participants (96.3%) had successful completions using a single dose of 400 mcg misoprostol. The majority of women (87.2%) found the side effects to be tolerable or easily tolerable. Most women (84.3%) were satisfied or very satisfied with the treatment they received; only one was dissatisfied (0.3%). Nine out of ten women would select this method again and recommend it to a friend (91.0% and 90.0%, respectively). This study confirms that 400 mcg sublingual misoprostol effectively evacuates

  5. Radiosterilization or sterilization by steam. Procedures for sterilization of spices

    Warmbold, J.

    1994-01-01

    The article compares two different methods for the sterilization of spices, namely radiosterilization and sterilization with steam. The first method applies ionizing radiation which can alter the chemical composition of the products. Tests have shown, however, that radiation doses up to 10 kGy will not induce the formation of carcinogenic agents in the foodstuffs, or of toxic substances, and thus are a wholesome method of preservation. Any modifications of taste, color or smell, or loss of vitamins, can be avoided by proper dose control and standard irradiation conditions. Sterilization by steam is a method achieving substantial suppression of the formation of germs, aerobic spores, yeasts, mould, and gramnegative germs, while preserving in most cases the essential oils. It may result in sensoric alterations, i.e affect the color, smell or taste, but in general the spices thus treated preserved their characteristic properties. The method is a good alternative to radiosterilization. The article adds some concluding information on mandatory labelling of irradiated food imported from third countries

    CONTEXT Abortion is highly restricted by law in Senegal. Although women seek care for abortion complications, no national estimate of abortion incidence exists. METHODS Data on postabortion care and abortion in Senegal were collected in 2013 using surveys of a nationally representative sample of 168 health facilities that provide postabortion care and of 110 professionals knowledgeable about abortion service provision. Indirect estimation techniques were applied to the data to estimate the incidence of induced abortion in the country. Abortion rates and ratios were calculated for the nation and separately for the Dakar region and the rest of the country. The distribution of pregnancies by planning status and by outcome was estimated. RESULTS In 2012, an estimated 51,500 induced abortions were performed in Senegal, and 16,700 (32%) resulted in complications that were treated at health facilities. The estimated abortion rate was 17 per 1,000 women aged 15–44 and the abortion ratio was 10 per 100 live births. The rate was higher in Dakar (21 per 1,000) than in the rest of the country (16 per 1,000). Poor women were far more likely to experience abortion complications, and less likely to receive treatment for complications, than nonpoor women. About 31% of pregnancies were unintended, and 24% of unintended pregnancies (8% of all pregnancies) ended in abortion. CONCLUSIONS Unsafe abortion exacts a heavy toll on women in Senegal. Reducing the barriers to effective contraceptive use and ensuring access to postabortion care without the risk of legal consequences may reduce the incidence of and complications from unsafe abortion.

    To investigate predictable ultrasonographic findings of early abortion. To investigate objective rules for the screening of abortion. Ultrasonographic examination of 111 early pregnancies between the sixth and ninth week in women who had regular 28 day menstrual cycles was performed. Ultrasonographic measurements of the gestational sac, crown rump length and fetal heart rate were performed using a linear array real time transducer with doppler ultrasonogram. All measurements of 17 early abortions were compared to those of 94 normal pregnancies. Most of early aborted pregnancies were classified correctly by discriminant analysis with G-SAC and CRL (G-SAC=0.5 CRL + 15, sensitivity 76.5%, specificity 96.8%). With the addition of FHR, 94.1% of early abortions could be predicted. In conclusion, ultrasonographic findings of early intrauterine growth retardation, small gestational sac and bradycardia can be predictable signs suggestive of poor prognosis of early pregnancies

METHODS: A cross-sectional questionnaire study was conducted in 2 phases at 3 hospitals in Tanzania. Phase 1 included 302 patients with a diagnosis of incomplete abortion......, and phase 2 included 823 such patients. RESULTS: In phase 1, in which cases were classified by clinical criteria and information from the patient, 3.9% to 16.1% of the cases were classified as induced abortion. In phase 2, in which the structured interview was changed to an empathetic dialogue...... and previously used clinical criteria were omitted, 30.9% to 60.0% of the cases were classified as induced abortion. CONCLUSIONS: An empathetic dialogue improves the quality of data collected among women with induced abortion....

  10. Reproductive rights: Current issues of late abortion

    Directory of Open Access Journals (Sweden)

    Full Text Available This article considers the legal issues surrounding induced late abortion in cases when severe medical, therapeutic or ethical reasons have not been in dispute. Generally discussing the essential question about abortion today, it means not anymore legality of abortion but, in the first place, safety of abortion. From the aspect of woman health the most important aim is to detect and avoid possible risks of medical intervention, such as late abortion present. This is the matter of medical law context and also the matter of the woman's reproductive rights, here observed through legislation and court practice. The gynecologist has an obligation to obtain the informed consent of each patient. Information's should be presented in reasonably understandable terms and include alternative modes of treatment, objectives, risks, benefits, possible complications, and anticipated results of such treatment. Pregnant woman should receive supportive counseling before and particularly after the procedure. The method chosen for all terminations should ensure that the fetus is born dead. This should be undertaken by an appropriately trained practitioner. Reform in abortion law, making it legally accessible to woman, is not necessarily the product of a belief in woman's rights, but can be a means of bringing the practice of abortion back under better control. Counseling and good medical practice in performing late abortion are the instruments to drive this point even further home. It does not undermine the woman who wants to make a positive decision about her life and its purpose is not to produce feelings of insecurity and guilt. It concludes that existing law should not be changed but that clear rules should be devised and board created to review late term abortion. In Serbia, this leads to creation and set up guidelines for reconciling medical justification for late abortion with existing law, especially with solutions which brings comparative law. .

  11. The abortion issue in the 1980 elections.

    The political opponents of legal abortion achieved considerable gains in the 1980 American elections. A president who was committed to a strong antiabortion position was elected, and antiabortion candidates prevailed in six out of seven Senate races that pitted supporters against opponents of legal abortion and in seven out of nine similar confrontations in the House races. However, it is not clear that abortion was an overriding or decisive factor in determining those outcomes. Democrats and Republicans, Carter voters and Reagan voters did not differ significantly in their attitudes toward abortion. The presidential voter groups were divided on several other issues, and along income and racial lines, to a far greater extent than they were on abortion. Voters were not likely to name abortion as one of the more important problems facing the nation. Carter supporters rated abortion as more important than did Reagan supporters. Although the party platforms and the presidential candidates were clearly differentiated in their abortion stands, these differences were not well communicated to the citizenry. When voters attempted to describe the position of each candidate on abortion, they displayed a great deal of uncertainty, error and confusion. In the key Senate races, those who voted for the prochoice candidates held more liberal abortion attitudes than those who voted for the right-to-life candidates. This difference, although statistically significant, was not great, and was smaller than the differences related to several other issues--such as attitudes toward the role of government, women's rights and economic policies.(ABSTRACT TRUNCATED AT 250 WORDS)

  12. If war is "just," so is abortion.

    Kissling, F

    1991-01-01

    Currently Catholic bishops are applying an inconsistent ethical paradigm to the issues of war and abortion. Based on the seamless garment theory war, abortion and capital punishment are all immoral acts because they are of the same garment. They are all "killing acts" and as such they are immoral. However there is within the Catholic paradigm the idea of a just war. The just war theory states that the destruction of human life in war is justified if it is for a greater good. However abortion has no exceptions, there is no just abortion in the rules of the Catholic Church. The author takes the just war doctrine as presented by the Catholic Church and shows how it could easily apply to abortion. Both war and abortion involve the taking of a human life, but in the case of war the taking of a life is justified if it is done to protect your own life. The same exception in abortion would be to allow abortion when the mother's life is in danger. yet no such exception exists. The just war theory further states that was is necessary to protect national integrity, particularly if the violation erodes the quality of life for its citizens. The same exception for abortion would include allowing abortions for women who already have more children then they can care for or if having the child would erode the quality of life for the woman. Other aspects of the just war theory include the competence and goals of the national leaders. Women must also be allowed to be competent moral agents. Proponents of the seamless garment theory will bring up the fact that in a just war only combatants die yet the fetus is innocent. But no war has ever been fought without the loss of innocent civilians.

    1987-01-01

    Eleven male-sterile mutants were induced from a rice variety Sasanishiki by ethyleneimine and γ-ray treatments of seeds. Nine of them produced no pollen grains or only abortive ones and the other two showed extremely low pollen fertilities. The eleven mutants were crossed with the original variety. All F 1 hybrids were fertile, i.e., normal in both pollen and seed fertilities. In eight of their F 2 progenies, fertile and male-sterile plants segregated in a ratio of 3 to 1, indicating that the male sterility of the eight mutants was controlled by a single recessive gene. In one of the other three, segregation ratio suggested the participation of two recessive genes, while in the remaining two, the number of the genes responsible for male sterility could not be determined.

    Spontaneous perforation of the gallbladder is one complication of cholelithiasis. There is a greater occurence of free perforation in the peritoneal cavity with bilary pertonitis, followed by the perforation into the stomach, small intestine and colon. A single case of the nowadays rare spontaneous perforation in and through the abdominal wall will be reported. Spontaneous gallbladder perforation appears nearly asymptomatic in its clinical course because of absent biliary peritonitis. (orig.) [de

    To determine the prevalence and correlates of having a regular physician among women presenting for induced abortion. We conducted a retrospective review of women presenting to an urban, university-based family planning clinic for abortion between January 2008 and September 2011. We conducted bivariate analyses, comparing women with and without a regular physician, and multivariable regression modeling, to identify factors associated with not having a regular physician. Of 834 women, 521 (62.5%) had a regular physician and 313 (37.5%) did not. Women with a prior pregnancy, live birth, or spontaneous abortion were more likely than women without these experiences to have a regular physician. Women with a prior induced abortion were not more likely than women who had never had a prior induced abortion to have a regular physician. Compared with women younger than 18 years, women aged 18 to 26 years were less likely to have a physician (adjusted odds ratio [aOR], 0.25; 95% confidence interval [CI], 0.10-0.62). Women with a prior live birth had increased odds of having a regular physician compared with women without a prior pregnancy (aOR, 1.89; 95% CI, 1.13-3.16). Women without medical/fetal indications and who had not been victims of sexual assault (self-indicated) were less likely to report having a regular physician compared with women with medical/fetal indications (aOR, 0.55; 95% CI, 0.17-0.82). The abortion visit is a point of contact with a large number of women without a regular physician and therefore provides an opportunity to integrate women into health care.

  17. Mirror model for sterile neutrinos

    2003-01-01

    Sterile neutrinos are studied as subdominant contribution to solar neutrino physics. The mirror-matter neutrinos are considered as sterile neutrinos. We use the symmetric mirror model with gravitational communication between mirror and visible sectors. This communication term provides mixing between visible and mirror neutrinos with the basic scale μ=v EW 2 /M Pl =2.5x10 -6 eV, where v EW =174 GeV is the vacuum expectation value of the standard electroweak group and M Pl is the Planckian mass. It is demonstrated that each mass eigenstate of active neutrinos splits into two states separated by small Δm 2 . Unsuppressed oscillations between active and sterile neutrinos (ν a ↔ν s ) occur only in transitions between each of these close pairs ('windows'). These oscillations are characterized by very small Δm 2 and can suppress the flux and distort spectrum of pp-neutrinos in detectable way. The other observable effect is anomalous seasonal variation of neutrino flux, which appears in LMA solution. The considered subdominant neutrino oscillations ν a ↔ν s can reveal itself as big effects in observations of supernova neutrinos and high-energy (HE) neutrinos. In the case of HE neutrinos they can provide a very large diffuse flux of active neutrinos unconstrained by the e-m cascade upper limit

    Evidence from developed countries has shown that abortion-related mortality and morbidity has decreased with the liberalization of the abortion law. This study aimed to assess the trend of hospital-based abortion complications during the transition of legalization in Ethiopia in May 2005. Medical records of women with abortion complications from 2003 to 2007 were reviewed (n = 773). Abortion and its complications with regard to legalization were described by rates and ratios, and predictors of fatal outcomes were analyzed by logistic regression. The overall and abortion-related maternal mortality ratios (AMMRs) showed a non-statistically significant downward trend over the 5-year period. However, the case fatality rate of abortion increased from 1.1% in 2003 to 3.6% in 2007. Late gestational age, history of interference and presenting after new abortion legislation passed have been found to be significant predictors of mortality. Decreased trends of abortion ratio and the AMMR were identified, but the severity of abortion complications and the case fatality rate increased during the transition of legal revision.

    Induced abortion contributes significantly to maternal mortality in developing countries yet women still seek repeat induced abortion in spite of availability of contraceptive services. The aim of this study is to determine the rate of abortion and contraceptive use among women seeking repeat induced abortion in Western Nigeria. A prospective cross-sectional study utilizing self-administered questionnaires was administered to women seeking abortion in private hospitals/clinics in four geopolitical areas of Ogun State, Western Nigeria, from January 1 to December 31 2012. Data were analyzed using SPSS 17.0. The age range for those seeking repeat induced abortion was 15 to 51 years while the median age was 25 years. Of 2934 women seeking an abortion, 23% reported having had one or more previous abortions. Of those who had had more than one abortion, the level of awareness of contraceptives was 91.7% while only 21.5% used a contraceptive at their first intercourse after the procedure; 78.5% of the pregnancies were associated with non-contraceptive use while 17.5% were associated with contraceptive failure. The major reason for non-contraceptive use was fear of side effects. The rate of women seeking repeat abortions is high in Nigeria. The rate of contraceptive use is low while contraceptive failure rate is high.

  1. Simulating sterilization, vaccination, and test-and-remove as brucellosis control measures in bison

    Brucella abortus, the causative agent of bovine brucellosis, infects wildlife, cattle, and humans worldwide, but management of the disease is often hindered by the logistics of controlling its prevalence in wildlife reservoirs. We used an individually based epidemiological model to assess the relative efficacies of three management interventions (sterilization, vaccination, and test-and-remove). The model was parameterized with demographic and epidemiological data from bison in Yellowstone National Park, USA. Sterilization and test-and-remove were most successful at reducing seroprevalence when they were targeted at young seropositive animals, which are the most likely age and sex category to be infectious. However, these approaches also required the most effort to implement. Vaccination was less effective (even with a perfect vaccine) but also required less effort to implement. For the treatment efforts we explored (50–100 individuals per year or 2.5–5% of the female population), sterilization had little impact upon the bison population growth rate when selectively applied. The population growth rate usually increased by year 25 due to the reduced number of Brucella-induced abortions. Initial declines in seroprevalence followed by rapid increases (>15% increase in 5 years) occurred in 3–13% of simulations with sterilization and test-and-remove, but not vaccination. We believe this is due to the interaction of superspreading events and the loss of herd immunity in the later stages of control efforts as disease prevalence declines. Sterilization provided a mechanism for achieving large disease reductions while simultaneously limiting population growth, which may be advantageous in some management scenarios. However, the field effort required to find the small segment of the population that is infectious rather than susceptible or recovered will likely limit the utility of this approach in many free-ranging wildlife populations. Nevertheless, we encourage

    Until 2006, legal induced abortion was completely banned in Colombia. Few facilities are equipped or willing to offer abortion services; often adolescents experience even greater barriers of access in this context. We examined post abortion care (PAC) and legal induced abortion in two large public hospitals. We tested the association of hospital site, procedure type (manual vacuum aspiration vs. sharp curettage), and age (adolescents vs. women 20 years and over) with service type (PAC or legal induced abortion). Retrospective cohort study using 2010 billing data routinely collected for reimbursement (N=1353 procedures). We utilized descriptive statistics, multivariable logistic regression and predicted probabilities. Adolescents made up 22% of the overall sample (300/1353). Manual vacuum aspiration was used in one-third of cases (vs. sharp curettage). Adolescents had lower odds of documented PAC (vs. induced abortion) compared with women over age 20 (OR=0.42; 95% CI=0.21-0.86). The absolute difference of service type by age, however, is very small, controlling for hospital site and procedure type (.97 probability of PAC for adolescents compared with .99 for women 20 and over). Regardless of age, PAC via sharp curettage is the current standard in these two public hospitals. Both adolescents and women over 20 are in need of access to legal abortion services utilizing modern technologies in the public sector in Colombia. Documentation of abortion care is an essential first step to determining barriers to access and opportunities for quality improvement and better health outcomes for women. Following partial decriminalization of abortion in Colombia, in public hospitals nearly all abortion services are post-abortion care, not induced abortion. Sharp curettage is the dominant treatment for both adolescents and women over 20. Women seek care in the public sector for abortion, and must have access to safe, quality services. Copyright © 2014.

    Measurements of neutrino oscillations at short baselines contain an intriguing set of experimental anomalies that may be suggestive of new physics such as the existence of sterile neutrinos. This three-part thesis presents research directed towards understanding these anomalies and searching for sterile neutrino oscillations. Part I contains a theoretical discussion of neutrino coherence properties. The open-quantum-system picture of neutrino beams, which allows a rigorous prediction of coherence distances for accelerator neutrinos, is presented. Validity of the standard treatment of active and sterile neutrino oscillations at short baselines is verified, and non-standard coherence loss effects at longer baselines are predicted. Part II concerns liquid argon detector development for the MicroBooNE experiment, which will search for short-baseline oscillations in the Booster Neutrino Beam at Fermilab. Topics include characterization and installation of the MicroBooNE optical system; test-stand measurements of liquid argon optical properties with dissolved impurities; optimization of wavelength-shifting coatings for liquid argon scintillation light detection; testing and deployment of high-voltage surge arrestors to protect TPC field cages; and software development for optical and TPC simulation and reconstruction. Part III presents a search for sterile neutrinos using the IceCube neutrino telescope, which has collected a large sample of atmospheric-neutrino-induced events in the 1-10 TeV energy range. Sterile neutrinos would modify the detected neutrino flux shape via MSW-resonant oscillations. Following a careful treatment of systematic uncertainties in the sample, no evidence for MSW-resonant oscillations is observed, and exclusion limits on 3+1 model parameter space are derived. Under the mixing assumptions made, the 90% confidence level exclusion limit extends to sin224 ≤ 0.02 at m2 ~ 0.3 eV2, and the LSND and Mini

    The available scientific literature on the health effects of abortion on women in the US neither supports nor refutes the premise that abortion contributes to psychological problems. The 250 studies that have considered the psychological aspects of abortion are all flawed methodologically. Needed to resolve this issue is a prospective study of a cohort of US women of childbearing age focused on the psychological effects of failure to conceive, as well as the physical and mental sequelae of pregnancy whether carried to delivery, miscarried, or terminated by abortion. The most desirable such study could be conducted for about US$100 million over a 5-year period; a less expensive yet satisfactory study could be conducted for $10 million over the same time frame. Before such a study can be undertaken, a survey instrument must be designed to eliminate the discrepancy between the number of abortions on record and the number of women who admit to having an abortion on survey. Another issue is that the health effects of abortion cannot easily be separated from the controversial social issues surrounding pregnancy termination.

    Oryza longistaminata originates from African wild rice and contains valuable traits conferring tolerance to biotic and abiotic stress. However, interspecific crosses between O. longistaminata and Oryza sativa cultivars are hindered by reproductive barriers. To dissect the mechanism of interspecific hybrid sterility, we developed a near-isogenic line (NIL) using indica variety RD23 as the recipient parent and O. longistaminata as the donor parent. Both pollen and embryo sac semi-sterility were observed in F 1 hybrids between RD23 and NIL. Cytological analysis demonstrated that pollen abortion in F 1 hybrids occurred at the early bi-nucleate stage due to a failure of the first mitosis in microspores. Partial embryo sacs in the F 1 hybrids were defective during the functional megaspore formation stage. Most notably, nearly half of the male or female gametes were aborted in heterozygotes S40 i S40 l , regardless of their genotypes. Thus, S40 was indicated as a one-locus sporophytic sterility gene controlling both male and female fertility in hybrids between RD23 and O. longistaminata. A population of 16 802 plants derived from the hybrid RD23/NIL-S40 was developed to fine-map S40. Finally, the S40 locus was delimited to an 80-kb region on the short arm of chromosome 1 in terms with reference sequences of cv. 93-11. Eight open reading frames (ORFs) were localized in this region. On the basis of gene expression and genomic sequence analysis, ORF5 and ORF8 were identified as candidate genes for the S40 locus. These results are helpful in cloning the S40 gene and marker-assisted transferring of the corresponding neutral allele in rice breeding programs.

    Hybrid sterility locus S37 between Oryza glaberrima and Oryza sativa results in both pollen and embryo sac sterility. Interspecific crossing between African cultivated rice Oryza glaberrima and Oryza sativa cultivars is hindered by hybrid sterility. To dissect the mechanism of interspecific hybrid sterility, we developed a near-isogenic line (NIL)-S37 using Dianjingyou1 (DJY1) as the recipient parent and an African cultivated rice variety as the donor parent. Empty pollen and embryo sac sterility were observed in F1 hybrids between DJY1 and NIL-S37. Cytological analyses showed that pollen abortion in the F1 hybrids occurred at the late binucleate stage due to a failure of starch accumulation in pollen grains. In addition, partial abortion of the embryo sac in the F1 hybrid was observed during function megaspore developing into mature embryo sac. Molecular analysis revealed that the semi-sterility was largely caused by the abortion of male and female gametophytes carrying the S37 allele from DJY1. A population of 25,600 plants derived from the hybrid DJY1/NIL-S37 was developed to fine map S37. Based on the physical location of molecular markers, S37 locus was finally delimited to a region of 205 kb on the short arm of chromosome 1 in terms of reference sequences of cv. Nipponbare. Interestingly, an about 97-kb DNA segment was deleted in the NIL-S37 based on BAC clone information of O. glaberrima. Fifty-four open reading frames (ORF) were predicted in this 205-kb region of DJY1, whereas only 31 ORFs were in that of NIL-S37. These results are valuable for cloning of S37 gene and further breaking reproductive isolation between Oryza glaberrima and Oryza sativa cultivars, as well as marker-assisted transferring of the corresponding neutral allele in rice breeding programs.

    Clothing is perceived to be second skin to the human body since it is in close contact with the human skin most of the times. In hospitals, use of textile materials in different forms and sterilization of these materials is an essential requirement for preventing spread of germs. The need for appropriate disinfection and sterilization techniques is of paramount importance. There has been a continuous demand for novel sterilization techniques appropriate for use on various textile materials as the existing sterilization techniques suffer from various technical and economical drawbacks. Plasma sterilization is the alternative method, which is friendlier and more effective on the wide spectrum of prokaryotic and eukaryotic microorganisms. Basically, the main inactivation factors for cells exposed to plasma are heat, UV radiation and various reactive species. Plasma exposure can kill micro-organisms on a surface in addition to removing adsorbed monolayer of surface contaminants. Advantages of plasma surface treatment are removal of contaminants from the surface, change in the surface energy and sterilization of the surface. Plasma sterilization aims to kill and/or remove all micro-organisms which may cause infection of humans or animals, or which can cause spoilage of foods or other goods. This review paper emphasizes necessity for sterilization, essentials of sterilization, mechanism of plasma sterilization and the parameters influencing it.

    To estimate the regret rate and risk factors for regret among women who have undergone sterilization. A retrospective study was conducted among all women who underwent a sterilization procedure at the University Medical Center Maribor, Maribor, Slovenia, in 2008-2012. Identified women were contacted and asked to complete an online questionnaire assessing regret and symptoms associated with depression. Among 714 identified women, 308 (43.1%) completed the questionnaire. Four (1.3%) participants reported regret, and 9 (2.9%) reported that they would not opt for sterilization again, all of whom had post-sterilization problems. Such problems were significantly associated with participants reporting that they would not opt for sterilization again (P=0.003). Additionally, women who would not choose sterilization again had significantly higher scores on the depressive scale used than did those who would undergo sterilization again (P=0.028). Few women report regret after tubal sterilization in Slovenia. However, an additional consultation on post-sterilization problems and depressive disorder before sterilization might minimize the risk of regret.

  12. Women plan condom use after sterilization.

    Sexual sterilization is highly effective in preventing pregnancy, but it does not protect against sexually transmitted diseases (STDs). People who accept sterilization as their method of family planning therefore need to be encouraged to protect themselves against HIV/AIDS and STDs even after they have been sterilized. Since women return less often to family planning providers following their sterilization procedure, they need to be advised to protect themselves against HIV and STDs before the sterilization is performed. 42% of the 2782 women who underwent tubal sterilizations at the Baylor College of Medicine in Houston during 1991-96 indicated their intention in a cross-sectional study to use condoms after sterilization. 20% of all respondents, aged 18-51 years, had a known risk factor for HIV, and almost 25% reported regular condom use for contraception or disease protection during the 3 months before sterilization. Planned condom use increased from 32% in 1991 to 51% in 1996, irrespective of age, marital status, or ethnic background. Of the 646 women who used condoms before being sterilized, almost half indicated no plans to do so after the procedure. The following factors were associated with condom use: relatively younger age, black ethnicity, unmarried status, history of previous STD, no steady partner, having a higher number of previous sex partners, past use of condoms to prevent disease transmission, and lack of partner involvement in the decision to undergo sterilization.

    Galectins are galactose binding proteins and, in addition, factors for a wide range of pathologies in pregnancy. We have analyzed the expression of prototype (gal-1, -2, -7, -10) and chimera-type (gal-3) galectins in the placenta in cases of spontaneous abortions (SPA) and recurrent abortions (RA) in the first trimester. Fifteen placental samples from healthy pregnancies were used as a control group. Nine placentas were examined for spontaneous abortions, and 12 placentas for recurrent abortions. For differentiation and evaluation of different cell types of galectin-expression in the decidua, immunofluorescence was used. For all investigated prototype galectins (gal-1, -2, -7, -10) in SPA and RA placenta trophoblast cells the expression is significantly decreased. In the decidua/extravillous trophoblast only gal-2 expression was significantly lowered, which could be connected to its role in angiogenesis. In trophoblasts in first-trimester placentas and in cases of SPA and RA, prototype galectins are altered in the same way. We suspect prototype galectins have a similar function in placental tissue because of their common biochemical structure. Expression of galectin 3 as a chimera type galectin was not found to be significantly altered in abortive placentas.

  14. Adolescent males, fatherhood, and abortion.

    The event of elective abortion to terminate unplanned pregnancies brought to the fore and allowed exploration of issues of fatherliness normally latent and, therefore, not observable in adolescence. This is consistent with the psychoanalytic view that fatherly development is an ongoing process begun long before actual parenthood, encompassing an array of conflicts and themes which are conscious to varying degrees in different developmental stages. Issues expressed by the group of adolescent boys studied were compared with those described in the psychoanalytic literature. Most prominent were regressive wishes for nurturance, competition with one's own father, and efforts to meet paternal ego ideals of maturity and responsibility. Parturition envy and strivings for immortality through offspring were not expressed in this group. Themes of fatherliness were not exclusive; they became intertwined with normal tasks of adolescence and individual dynamics as is illustrated with a clinical case.

    Between December 1990 and May 1991 in Malaysia, clinicians at the Sultanah Aminah Hospital in Johor Bahru screened 200 women with a diagnosis of threatened miscarriage with ultrasound to determine whether ultrasound could evaluate the viability of the fetus and thus the outcome of pregnancy in cases of threatened abortion. A fetal heartbeat was absent in 65% of cases with the remaining 35% of cases having a fetal heartbeat. Nonviability of the fetus or an abnormal or very early pregnancy may have accounted for an absent fetal heartbeat. The pregnancy of 46% of cases continued while 41% experienced spontaneous abortion. Just 6.2% of cases with a fetal heartbeat suffered from spontaneous abortion compared with 69.7% of those without a fetal heartbeat. 93.8% of cases with a fetal heartbeat continued their pregnancies compared with 30.3% of those without a fetal heartbeat. Inability of ultrasound to detect fetal heartbeats during early pregnancy probably accounted for the somewhat high percentage of those without a fetal heartbeat who continued their pregnancies. Among patients with a fetal heartbeat, the number of pregnancies that continued. Ultrasound detected 13% abnormal pregnancies (i.e., molar pregnancy or ectopic pregnancy). Surgery on these cases confirmed the ultrasound findings. These results showed that ultrasound should be used in every case of threatened miscarriage and that a fetal heartbeat does indicate the viability of the fetus.

    To minimize the beam losses at the moment of an LHC beam dump the 3 μs long abort gap should contain as few particles as possible. Its population can be minimised by abort gap cleaning using the LHC transverse damper system. The LHC Run 1 experience is briefly recalled; changes foreseen for the LHC Run 2 are presented. They include improvements in the observation of the abort gap population and the mechanism to decide if cleaning is required, changes to the hardware of the transverse dampers to reduce the detrimental effect on the luminosity lifetime and proposed changes to the applied cleaning algorithms.

    Unsafe abortion remains a huge problem in Nepal even after legalization of abortion. Various myths and misconceptions persist which prompt women towards unsafe abortive practices. A qualitative study was conducted among different groups of women using focus group discussions and in depth interviews. Perception and understanding of the participants on abortion, methods and place of abortion were evaluated. A number of misconceptions were prevalent like drinking vegetable and herbal juices, and applying hot pot over the abdomen could abort pregnancy. However, many participants also believed that health care providers should be consulted for abortion. Although majority of the women knew that they should seek medical aid for abortion, they were still possessed with various misconceptions. Merely legalizing abortion services is not enough to reduce the burden of unsafe abortion. Focus has to be given on creating awareness and proper advocacy in this issue.

    Unsafe abortion continues to be a major cause of maternal death; it accounts for 14.5% of all maternal deaths globally and almost all of these deaths occur in countries with restrictive abortion laws. A strong body of accumulated evidence shows that the simple means to drastically reduce unsafe abortion-related maternal deaths and morbidity is to make abortion legal and institutional termination of pregnancy broadly accessible. Despite this evidence, abortion is denied even when the legal con...

  2. Birth planning and sterilization in China.

    Sterilization is the most prevalent method of contraception in China. Approximately half of all women of reproductive age report that they or their husbands are sterilized. Using data from the China Health and Nutrition Survey we describe patterns of sterilization in eight Chinese provinces. With a discrete-time event history model we investigate the link between characteristics of local birth planning policy and the risk of sterilization. After controlling for parity, the risk of sterilization is highest in communities where birth planning policy is least strong as measured by exceptions to the one-child policy. These results suggest that couples with more flexibility in family building may have less control over contraceptive method use. Other factors affecting the risk of sterilization are a woman's age, parity, and whether or not she has a son. Our results emphasize the importance of taking into account multiple dimensions of reproductive behaviour when assessing one-child policy changes.

    To assess whether a social marketing initiative focusing on medicated abortion via a mifepristone/misoprostol "combipack" has contributed to reducing unsafe abortion in Cambodia. In a questionnaire-based cross-sectional study, annual household surveys were conducted across 13 Cambodian provinces in 2010, 2011, and 2012. One married woman of reproductive age who was not pregnant and did not wish to be within the next 2 years in each randomly selected household was approached for inclusion. Participants were interviewed using a structured questionnaire. The questionnaire was completed by 1843 women in 2010, 2068 in 2011, and 2059 in 2012. Manual vacuum aspiration was reported by 61 (72.6%) of 84 women surveyed in 2010 who reported an abortion in the previous 12 months, compared with only 28 (52.8%) of 53 in 2012 (P=0.001). The numbers of women undergoing medicated abortion increased from 22 (26.2%) of 84 in 2010 to 27 (49.1%) of 53 in 2012 (P=0.003), whereas the numbers undergoing unsafe abortion decreased from 4 (4.8%) in 2010 to 0 in 2012 (P=0.051). Social marketing of medication abortion coupled with provider training in clinical and behavioral change could have contributed to a reduction in the prevalence of unsafe abortion and shifted the types of abortion performed in Cambodia, while not increasing the overall number of abortions. © 2016 International Federation of Gynecology and Obstetrics.

    In this paper, we introduce a food irradiation with low energetic, lower than 300keV, electrons (so-called SOFT ELECTRON) as a rather new method of food sterilization. It is also a physical sterilization method, and free from the problems mentioned above. Low energetic electrons have small penetration power (50-200micron) through raw materials, and by selecting a proper energy of electrons we can sterilize only the surfaces or skins of target materials

  6. Stigma and abortion complications in the United States.

    2012-12-01

    Abortion is highly stigmatized in the United States and elsewhere. As a result, many women who seek or undergo abortion keep their decision a secret. In many regions of the world, stigma is a recognized contributor to maternal morbidity and mortality from unsafe abortion, even when abortion is legal. Women may self-induce abortion in ways that are dangerous, or seek unsafe clandestine abortion from inadequately trained health care providers out of fear that their sexual activity, pregnancy, or abortion will be exposed if they present to a safe, licensed facility. However, unsafe abortion rarely occurs in the United States, and accordingly, stigma as a cause of unsafe abortion in the United States context has not been described. I consider the relationship of stigma to two serious abortion complications experienced by U.S. patients. Both patients wished to keep their abortion decision a secret from family and friends, and in both cases, their inability to disclose their abortion contributed to life-threatening complications. The experiences of these patients suggest that availability of legal abortion services in the United States may not be enough to keep all women safe. The cases also challenge the rhetoric that "abortion hurts women," suggesting instead that abortion stigma hurts women.

    This study analyzes ethnic differences in induced abortion among ever-married women in Kazakstan, drawing on data from the 1995 Kazakstan Demographic and Health Survey. Instead of conventional ethnic markers, such as "Kazak" or "Russian," it focuses on more complex ethnocultural identities that combine ascribed ethnicity with language use. Because of the history of russification in Kazakstan, three ethnocultural groups are defined and compared--Kazak women who chose to be interviewed in Kazak, Kazak women who chose to be interviewed in Russian, and women of European background interviewed in Russian. Whereas women of European origin were the most likely to undergo induced abortion, the Russian-interviewed Kazaks had higher abortion ratios and were more likely to terminate their pregnancies than were the Kazak-interviewed Kazaks, net of other characteristics. The implications of the results for induced abortion trends and family planning policy in Kazakstan are discussed in addition to other findings.

    2004-01-01

    Safe operation of the LHC beam dump relies on the possibility of firing the abort kicker at any moment during beam operation. One of the necessary conditions for this is that the number of particles in the abort gap should be below some critical level defined by quench limits. Various scenarios can lead to particles filling the abort gap. Time scales associated with these scenarios are estimated for injection energy and also coast where synchrotron radiation losses are not negligible for uncaptured particle motion. Two cases are considered, with RF on and RF off. The equilibrium distribution of lost particles in the abort gap defines the requirements for maximum tolerable relative loss rate and as a consequence the minimum acceptable longitudinal lifetime of the proton beam in collision.

    Full Text Available This study was conducted to develop and characterize a novel cytoplasmic male sterile (CMS source which was identified from Dongxiang wild rice (Oryza rufipogon by crossing Dongxiang wild rice as female with Zhongzao 35, an indica inbred variety, as male and continuous backcrossing with Zhongzao 35. Observation under optical microscope manifested that this novel CMS belonged to typical abortion type with less pollen compared with wild abortive type cytoplasm (CMS-WA. Sequential planting showed that this novel CMS has complete and stable male sterility. Testcross experiment showed that all the 24 tested materials including maintainer and restorer lines of CMS-WA and Honglian type cytoplasm (CMS-HL and other indica inbred varieties are the maintainers with complete maintaining ability, suggesting that this novel CMS has fertility restoration totally different from CMS-WA and CMS-HL and belongs to a novel type of CMS. So far, we only discovered a unique fertility restoration source for this novel CMS. Inheritance analysis showed that the fertility restoration of this CMS was governed by three pairs of independent dominant genes. Prospect for application of this novel CMS system in hybrid rice breeding was also discussed.

    The new approach of radiation sterilization -cryoradiosterilization with programmed freezing - was developed for pharmaceutical solutions. Both scientific and technical problems are solved, the results are discussed. Programmed freezing of vials with the drug's solutions provides the high stability of soluted components with biological activity at sterilizing irradiation without significant change of sterilization doses. Physical, chemical, biological and pharmacological properties of a lot of drug solutions for injection satisfy official requirements after cryoradiation sterilization treatment. This method seems to be especially important for the protein systems which could be infected by dangerous viruses (VIH, hepatitis B): blood plasma, diagnostic sera, protein preparations manufactured from donor's blood, etc. (Author)

The possibility of approximation q(m) by Poisson distribution is demonstrated. The diagrams are presented permitting to evaluate the dose which provides the defined reliability of sterilization of food for chicken-gnotobionts

    Sterile neutrino dark matter, a popular alternative to the WIMP paradigm, has generally been studied in non-supersymmetric setups. If the underlying theory is supersymmetric, we find that several interesting and novel dark matter features can arise. In particular, in scenarios of freeze-in production of sterile neutrino dark matter, its superpartner, the sterile sneutrino, can play a crucial role in early Universe cosmology as the dominant source of cold, warm, or hot dark matter, or of a subdominant relativistic population of sterile neutrinos that can contribute to the effective number of relativistic degrees of freedom Neff during big bang nucleosynthesis.

    Sterilization is now the method of family planning most commonly used in the world. Over the last 150 years, research has evolved in the search for the ideal method of female sterilization. The procedure should ideally have high efficacy, be readily accessible and be personally and culturally acceptable. The method should be simple, quick, easily learned and be able to be performed in an outpatient setting without general anesthesia. The most common and effective method for sterilization has, thus far, been via the laparoscopic route. Hysteroscopic sterilization, however, potentially fulfills many of these ideal criteria, but until recently has remained more of a concept than a reality.

  17. Genetic basis of the sterile insect technique

    2014-01-01

    The use of the sterile insect technique for insect control relies on the introduction of sterility in the females of the wild population. This sterility is produced following the mating of these females with released males carrying, in their sperm, dominant lethal mutations that have been induced by ionizing radiation. As well as radiation-induced sterility, natural mechanisms can be recruited, especially the use of hybrid sterility. Radiation is usually one of the last procedures that insects undergo before leaving mass-rearing facilities for release in the field. It is essential that the dosimetry of the radiation source be checked to ensure that all the insects receive the required minimum dose. A dose should be chosen that maximizes the level of introduced sterility in the wild females in the field. Irradiation in nitrogen can provide protection against the detrimental somatic effects of radiation. Currently, the development of molecular methods to sterilize pest insects in the field, by the release of fertile insects carrying trans genes, is very much in vogue. It is concluded that using a physical process, such as radiation, will always have significant advantages over genetic and other methods of sterilization for the large-scale application of the sterile insect technique.

Courts should consider evidence of stigma when evaluating laws regulating abortion or surrogacy to determine whether these laws are based on impermissible gender stereotyping. © 2015 American Society of Law, Medicine & Ethics, Inc.

  20. The triviality of abortion in Greece.

    Science.gov (United States)

    Naziri, D

    1991-09-01

    In Greece modern contraceptive methods are used only in a very limited manner and abortion is the primary form of birth control. There are several social and psychological issues that are considered to be responsible. A 1985 study done for the Family Planning Center of Thessaloniki found that the ratio of live births is 1.3 and the ratio of abortion is 1.8/woman. 88% of women in the study had had an abortion while practicing coitus interruptus. 90% of the women never bought condoms. In a 1989 study only 6% of women had a positive attitude about condoms. Abortion is used as the primary method of birth control regardless of a woman's socioeconomic status. Further it was found that abortion did not correlate with other modern attitudes or the emancipation of women. The decision to abort was related to difficulties and constraints inherent in bring up a child. However positive attitudes toward contraception were related to educational and occupational levels. To complicate matters the information concerning contraceptives was problematic and related to the women's own lack of initiative to find out, and a lack of correct information offered from gynecologists. A 1990 study on knowledge, attitudes, beliefs and practices in relation to HIV infection indicated that the most favored method of contraception was condoms, but 60.8% of the men reported use versus 33.7% of the women. However these figures are not very representative because the survey was given in the context of HIV prevention and no attempt was made to distinguish between regular and irregular use patterns. Abortions is not a moral issue in Greece. It was legalized in 1986 only because it came to the attention of the government that the previous prohibition was being completely ignored. Abortion is strongly affected by social and psychological factors that are complex and result from cultural view points about fertility, maternal value, and life itself that are unique to the Greek culture.
