    Somatic hybridization is performed to obtain significant cytoplasmic male sterility (CMS) lines, whose CMS genes are derived either from the transfer of sterile genes from the mitochondrial genome of donor parent to the counterpart of receptor or production of new sterile genes caused by mitochondrial genome recombination of the biparent during protoplast fusion. In this study, a novel male sterile line, SaNa-1A, was obtained from the somatic hybridization between Brassica napus and Sinapis alba. The normal anther development of the maintainer line, SaNa-1B, and the abortive process of SaNa-1A were described through phenotypic observations and microtome sections. The lforal organ of the sterile line SaNa-1A was sterile with a shortened iflament and delfated anther. No detectable pollen grains were found on the surface of the sterile anthers. Semi-thin sections indicated that SaNa-1A aborted in the pollen mother cell (PMC) stage when vacuolization of the tapetum and PMCs began. The tapetum radically elongated and became highly vacuolated, occupying the entire locule together with the vacuolated microspores. Therefore, SaNa-1A is different from other CMS lines, such as ogu CMS, pol CMS and nap CMS as shown by the abortive process of the anther.

    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. PMID:26850149

    14 isoplasmic and allonuclear cytoplasmic male sterile lines were used as female parents, 8 tester lines as male parents, 101 F1 progenies were obtained. Fertility restoration response of 101 F1 progenies were investigated through field observation and pollen stainability examination under microscope. 14 isoplasmic and allonuclear cytoplasmic male sterile lines were developed by repeated backcross with recurrent male parent lines for more than 8 generations. The result shows: tester line Zifeng1 not only restored the isoplasmic and allonuclear sterile lines of group C backcrossed with Mo17, Yu30 and Heer, but also completely restored the isoplasmic and allonuclear cytoplasm male sterile lines of group T backcrossed with Mo17, HZS , 1792 ,292 and Yu30. Therefore, nuclear background limits the use of Zifeng1 as a tester for identification of cytoplasmic male sterility. Furthermore RFLPs of mitochondrial DNA of 6 isonuclear and alloplasmic cytoplasmic male sterile lines were analyzed with Bam H Ⅰ and Hind Ⅲ restriction endonuclease and mitochondrial DNA probes pBcmH3 and Cox Ⅱ. The same RFLPs were found within sterile cytoplasm of group C, including C,Chuan G, Lei 2 and Lei 3, but a different RFLP pattern was observed among sterile cytoplasm of group S, C,T and the normal cytoplasm. This result suggested that the RFLP markers tightly linked to sterile mitochondrial genes of different groups could be applied in the identifcation of cytoplasmic male sterility.

  4. The epididymis, cytoplasmic droplets and male fertility

    2011-01-01

    The potential of spermatozoa to become motile during post-testicular maturation,and the relationship between the cytoplasmic droplet and fertilizing capacity are reviewed.Post-testicular maturation of spermatozoa involves the autonomous induction of motility,which can occur in vivo in testes with occluded excurrent ducts and in vitro in testicular explants,and artefactual changes in morphology that appear to occur in the testis in vitro.Both modifications may reflect time-dependent oxidation of disulphide bonds of head and tail proteins.Regulatory volume decrease(RVD),which counters sperm swelling at ejaculation,is discussed in relation to loss of cytoplasmic droplets and consequences for fertility.It is postulated that:(i)fertile males possess spermatozoa with sufficient osmolytes to drive RVD at ejaculation,permitting the droplet to round up and pinch off without membrane rupture; and(ⅱ)infertile males possess spermatozoa with insufficient osmolytes so that RVD is inadequate,the droplet swells and the resulting flagellar angulation prevents droplet loss.Droplet retention at ejaculation is a harbinger of infertility caused by failure of the spermatozoon to negotiate the uterotubal junction or mucous and reach the egg.In this hypothesis,the epididymis regulates fertility indirectly by the extent of osmolyte provision to spermatozoa,which influences RVD and therefore droplet loss.Man is an exception,because ejaculated human spermatozoa retain their droplets.This may reflect their short midpiece,approximating head length,permitting a swollen droplet to extend along the entire midpiece; this not only obviates droplet migration and flagellar angulation but also hampers droplet loss.

    2003-01-01

    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.

    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.

    A glutathione S-transferase gene (gst) has been introduced into restorers of cytoplasmic male sterility in upland cotton ( Gossypium hirsutum L. ) using Agrobacterium-mediated transformation. A transviable pollens of hybrid (sterile line×restorer) F1. The hybrid gave 3.6 more bolls per plant, 10.1% less aborted seeds and 10.6% more lint yield when ‘Zheda strong restorer’ was used as male parent than when ‘DES-HAF277’ was. Southern and Northern bloting analysis showed that the foreign gst gene was detectable and highly expressed in ‘Zheda strong restorer’.

  8. Development of Japonica Male Sterile Lines Integrating Cytoplasmic Male Sterility and Photosensitive Genic Male Sterility

    2005-01-01

    It has been previously established that the BT type of cytoplasmic male sterility (CMS) is induced by high temperatures,while photosensitive genic male sterility (PGMS) seed sets by low temperatures induce. In the current study, we have bred photosensitive cytoplasmic male sterility (PCMS) lines (2308SA and 2310SA) by crossing the CMS line with the PGMS japonica line with maintainer genes. The sterility of PCMS japonica was consequently controlled by two groups of male sterile genes resulting from the integration of PGMS and CMS genes. The results on plant fertility, at different sowing times, were as follows: (a) Under conditions of natural long-day photoperiod and at temperatures above 35℃, the PGMS gene regulated PCMS japonica sterility - the higher the temperature, the lower the pollen fertility. However, bagged seed sets of PCMS japonica, not exposed to high temperatures, induced the CMS seed set. (b) Exposure to long-day photoperiod and temperature conditions between 35℃ and the critical sterility inducing temperature of PGMS resulted in both PGMS and CMS gene controlled sterility of PCMS japonica, which exhibited stable characteristics. (c) When exposed to critical sterility inducing temperatures or short-day photoperiod and daily high temperatures below 32℃, the BT type of the CMS gene regulated PCMS sterility. Under these conditions, the PGMS gene rendered male sterility insusceptible to occasional cool summer days when this PCMS line, adopted for hybrid seed production, develops into panicle differentiation stage.The present study also investigated the fertility restoration, seed production and combining ability of PCMS japonica so as to optimize its use.

    Reactive oxygen species (ROS) in plant cell, including superoxide (O2-·), hydrogen peroxide (H2O2), and malondialdehyde (MDA), are thought to be important inducible factors of cell apoptosis if excessively accumulated in cells. To elucidate the metabolic mechanism of ROS production and scavenging in anthers of the cytoplasmic male-sterile (CMS) cotton,CMS line, maintainer, and hybrid F1 anthers, were employed for studying the relationship between CMS and metabolism of ROS, by comparing ROS changes in the sterile and fertile anthers at different developmental stages. The results showed that during the abortion preliminary stage (sporogenous cell division stage), anthers of CMS line had higher contents of O2-·, H2O2, and MDA than those of maintainer or hybrid F1. Simultaneously, the higher activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) in scavenging ROS were measured in the anthers of the CMS line,indicating that an increase of ROS in anthers of abortion preliminary stage had an inducible effect on the antioxidant enzymes. But during the abortion peak of CMS anther (pollen mother cell meiosis stage), on the one hand, contents of O2-·,H2O2, and MDA were extraordinarily high in CMS anthers, on the other hand, the activities of SOD, CAT, and POD were excessively low, which disrupted the balance between the production and elimination of ROS and led to pollen mother cells apoptosis at this stage. In the following two stages (uninucleate microspore stage and mature pollen stage), the contents of O2-· and H2O2 in the aborted anthers were approximated to contents in the fertile anthers of the maintainer and hybrid F1. However, MDA contents were continuously raised and enzymic activities of SOD, CAT, and POD were consistently decreased in sterile anthers, which indicated that ROS still had harmful effects on the anthers after the apoptosis of the male cells. Excessive accumulation of O2-·, H2O2, and MDA and significant reduction of ROS

  10. Expression of ogu cytoplasmic male sterility in cybrids of Brassica napus.

    1992-03-01

    A light and electron microscopic investigation revealed that ogu cytoplasmic male sterility (CMS) in cybrids of Brassica napus is primarily a deficiency of the tapetum and clearly time and site specific. Three patterns of ogu CMS were found, and specific conclusions drawn. First, the partially male fertile cybrid 23 was highly variable. It sometimes produced heterogeneous stamens with an endothecium formed exclusively around the fertile locules, thus delineating each microsporangium as a functional unit. The second type, including cybrids 27, 58 and 85, on the contrary, was stable and completely male sterile. In the four locules of normal length, microspores were observed to die at the vacuolate polarized stage while the tapetum disappeared prematurely through excessive vacuolization by the end of meiosis followed by a rapid autolysis during the tetrad or early free microspore stage. The subepidermal layer of the locule wall failed to form characteristic thickenings. The male-sterile stamens were completely indehiscent. At the time of anthesis they contained only collapsed empty exines adhering to each other. These cybrids, 27, 58 and 85, were closest to the ogu CMS trait of radish and seemed to be the best suited for further use in plant breeding. The third pattern was found in cybrids 77 and 118, which besides showing abortion of the microsporangia also showed a feminization of the stamens. We suggest that this feminization might be due to an alloplasmic situation associating Brassica napus nuclear genes with the mitochondrial DNA of radish. PMID:24202671

  11. Genetic and molecular basis of cytoplasmic male sterility in maize

    Parvez A. Sofi

    2007-08-01

    Full Text Available Cytoplasmic male sterility is a maternally inherited trait that suppresses pollen production due to the interaction of nuclear and mitochondrial genomes. In maize three types of CMS systems, namely CMS-T, CMS-S and CMS-C, have been documented and are differentiated by the reaction to restorers, mitochondrial DNA restriction digest patterns, and complements of low molecular weight plasmids. CMS-T is restored fully by Rf-1 and Rf-2, CMS-S by Rf-3, and CMS-C by Rf-4. All restorer genes except Rf-2 restore fertility by affecting the transcript profile of CMS-associated locus. The sterility is caused by the disorganization of the tapetum and surrounding cell layers as a result of the expression of pollen specific genes. Even though such phenotypes are associated with gene dysfunction in mitochondria, the chloroplasts have emerged as ideal organs for engineering male sterility in crop plants. A number of systems such as barnase-barstar have been standardized in Brassica. Recently, polyhydroxy butyrate was identified as a potential candidate gene for engineering male sterility. Moreover, a broad group of proteins called PPR (pentatricopeptide repeat proteins has also shown to hold great promise for engineering male sterility in crop plants as most of the restorers belong to this category. In maize one such protein, CRP-1, has been identified

  13. 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.

  14. Abortion.

    Savage, A

    1979-09-15

    I refer for termination anyone who requests it for--pace Mr V Tunkel, (28 July, p 253)--the law is generally regarded as being one of "abortion on demand." I have some misgivings as I do not believe that women in early pregnancy are always in a fit state to make a considered decision, and they cannot in the nature of things be given time. I have, however, become increasingly worried about the morbidity arising from the procedure, and it is interesting that letters on the subject (25 August, pp 495 and 496) should be followed by one reporting rupture of the uterus during prostaglandin-induced abortion--yet another complication to add to those of cervical incompetence, pelvic sepsis, and permanent neurological damage. In so far as these tragedies usually follow late terminations Mr John Corrie's Bill is to be welcomed. A few further points. I am not so cynical as to think that every impregnation is the result of a thoughtless act of male lust. Unlike Professor Peter Huntingford (25 August, p 496), I listen to men as well as women, and many of them are deeply involved emotionally in the pregnancy they have helped to produce. Certainly I think a man should have the right to be consulted if his wife is to undergo a procedure that might damage her health. It is unfair contemptuously to dismiss as "whims" opinions that differ from ones own. These may result from genuine conscientious doubts or inability to cope from overwork and understaffing. Abortion is quite the most expensive form of contraception, and perhaps in these days of financial stringency this should be taken into account. "Bigotry" is defined in my dictionary as "blind zeal." This could be said of those who enthusiastically promote a course of action without regard to circumstances, safety, or cost. PMID:497770

  15. Genetics of Fertility Restoration in Cytoplasmic Male Sterile Pepper

    2006-01-01

    Pepper hybrid seeds production using male sterility could lower cost by reducing time and labour, and increase the genetic purity of the F1 seeds. To investigate the genetics of fertility restoration of the Peterson cytoplasmic sterility in pepper, a doubled haploid population of 115 pepper lines obtained from anther culture of the F1 hybrid between Yolo Wonder (sterility maintainer line) and Perennial (fertility restorer line) and the parental lines were test-crossed by 77013A (a strict cytoplasmic-genic male sterile line). The fertility of the test-crossed lines was assessed in greenhouse and open field with the following three criteria: pollen index (PI, visual estimation of pollen amount per flower), pollen number (PN, pollen counting under microscope), and seed number (SN, the number of seeds per fruit in open pollination). Correlations between the each couple of criteria within, as well as between the cultivation methods ranged from 0.55 to 0.84. Analysis of variance showed that the genotype (DH line) and environment were the significant sources of variation of the fertility.Narrow sense of heritance of fertility restoration ranged from 0.38 to 0.92, depending on the criteria and environment. The distribution of the progeny was continuous between the parental genotypes indicating the quantitative inheritance of fertility restoration. Inferred from segregation according to Snape et al.(1984), the number of segregating genes was estimated to be that three to four genetic factors were involved in pollen traits (PI and PN) and five to eight genetic factors in seed production (SN). The heredity analysis of the CMS will be helpful for understanding of the genetic mechanism of the fertility restoration and the exploitation of the CMS in hybrid seed production.

  17. Abortion.

    1993-09-01

    Vacuum aspiration, dilatation and curettage, hysterotomy, and, in some cases, hysterectomy comprise surgical methods of abortion. Oral administration of RU-486, epostane, prostaglandins E and F2 and vaginal suppositories of prostaglandins E and F2 are medical abortion methods. The traditional or clandestine methods are usually performed by unqualified persons and pregnant women themselves. These methods tend to be inefficient and harmful. They include oral preparations of herbs and drugs (e.g., quinine and ergot), introduction of fluids (e.g., household disinfectants) into the vagina, introduction of foreign bodies (e.g., twigs, stems, hollow tubes, needles, wire) into the uterus. Hospital records, death certificates, and community-based surveys are common sources of data on abortion. Worldwide, 40-70/1000 women of childbearing age undergo an abortion. 20-33% of all pregnancies are terminated. Abortion is always legal when it is performed to save a pregnant woman's life. In most countries, it is legal to protect the woman's physical or mental health against serious danger. The risk of death from a legal abortion is rare. On the other hand, when an abortion is performed by an unqualified, unskilled abortionist and/or under unhygienic conditions (all of which are common in countries who have a law against abortion) the risk of death is much higher. In fact, abortion is one of the leading causes of maternal death in many countries (25% and 86% of maternal deaths in Bangladesh and Romania, respectively). Common complications of abortion are incomplete abortion, trauma to pelvic organs (e.g., uterine perforation), tetanus, and infertility. In some developing countries, the cost of treating abortion complications account for up to 50% of maternity hospital budgets. Ways to reduce mortality from unsafe abortion include promoting contraceptive use, legalizing abortion, allowing trained practitioners to perform abortions for health reasons, and improving clinical management

  20. Effects of nuclear genomes on anther development in cytoplasmic male sterile chicories (Cichorium intybus L.): morphological analysis.

    Habarugira, Ildephonse; Hendriks, Theo; Quillet, Marie-Christine; Hilbert, Jean-Louis; Rambaud, Caroline

    2015-01-01

    The Cichorium intybus flower development in fertile, cytoplasmic male sterility (CMS 524) and various phenotypes carrying the 524 male sterile cytoplasm was investigated macroscopically and by light microscopy. The development was similar in fertile and in male sterile florets up to meiosis, and then it was affected in anther wall structure and pollen grain development in male sterile floret. In the male sterile plants, the tapetum intrusion after meiosis was less remarkable, the microspores started to abort at vacuolate stage, the connective tissue collapsed, and endothecium failed to expand normally and did not undergo cell wall lignification, which prevented anther opening since the septum and stomium were not disrupted. Crosses undertaken in order to introduce the CMS 524 into two different nuclear backgrounds gave rise to morphologically diversified progenies due to different nuclear-mitochondrial interactions. Macroscopic and cytological investigations showed that pollen-donor plants belonging to Jupiter population had potential capacity to restore fertility while the CC line could be considered as a sterility maintainer.

  2. Induction of cytoplasmic male sterility by gamma-ray and chemical mutagens in sugar beets

    Male sterile plants appeared in the population of N cytoplasm sugar beet strains, H-19 and H-2002, when their dry seeds were exposed to 50 kR gamma-ray, and the male sterility was maintained up to the M4 generation through the mother plants. Cytoplasmic inheritance was confirmed by the reciprocal crossings between plants with normal phenotype from gamma-strains (progeneis of the male mutants which transmitted male sterility through the mother plants) and H-19 or H-1001. The crossing experiments suggested that various kinds of cytoplasm were induced by gamma-ray irradiation, and that different nuclear genes were responsible for the respective cytoplasms. A specific relationship between the pollen restoring genes and the sterile cytoplasms was established, and was named ''one set of pollen restoring genes for one cytoplasm''. It is probable that the cytoplasmic mutation occurred in normal cytoplasm strains and the specific combination between the altered cytoplasm and the recessive nuclear gene produced male sterility. Ethyl methane sulphonate, ethidium bromide, acriflavine and streptomycin were also effective in inducing cytoplasmic mutation in sugar beets. (Kaihara, S.)

  3. Genetic variation among the male sterile cytoplasms induced by gamma irradiation in sugar beets

    In sugar beets, cytoplasmic male sterility was induced artificially by radiation treatment. In the present study, four kinds of male sterile strain made from the strain H-2002 with normal cytoplasms were used, and the mode of inheritance of the sterility maintained by these strains was confirmed. Also the hereditary mechanism of pollen fructification recovery was studied, and the newly induced heterotypic property of sterile cytoplasms was examined in comparison with naturally found sterile strains. In each of four produced strains, the male sterility was inherited down to M4 lines stably through mother plants, and it was presumed that the sterility was caused by highly stable cytoplasmic mutation. In each strain, two pairs of nuclear genes took part in the recovery of pollen fructification, but the mode of action of two genes was different. As the result of mating for verification with O type strain to S cytoplasm strain, it seemed that at least the function as O type was not shown to three strains of γ-60, γ-114 and γ-165, and in the sterile cytoplasms of these three strains, the action of fructification recovery genes different from X and Z arose. It was presumed that the genes of X locus did not take effect in these induced cytoplasms. The possibility that at least four kinds of male sterile cytoplasms different from S were induced from normal cytoplasms by artificial mutation was proved indirectly. (Kako, I.)

  5. Downy mildew incidence of pearl millet hybrids with different male-sterility inducing cytoplasms.

    Yadav, O P

    1996-02-01

    The use of different sources of cytoplasmic male sterility (CMS) in hybrid seed production of pearl millet [Pennisetum glaucum (L.) R. Br.] is advocated to avoid possible disease epidemics occurring due to cytoplasmic uniformity. The effects of commercially unexploited, but potentially exploitable, sources of CMS, like A2, A3 and A4, on downy mildew [Sclerospora graminicola (Sacc.) Schroet] incidence were studied by using the disease incidence of isonuclear hybrids with male-sterile and fertile cytoplasm. The mean downy mildew incidence of hybrids carrying different male-sterile cytoplasm was similar to that of hybrids retaining the fertile cytoplasm. The cytoplasm accounted for only 0.6% of the total variation and its effect was non-significant; pollinators could explain most of the variation in determining the disease incidence of hybrids. This suggested that these male-sterile cytoplasms are not linked to downy mildew susceptibility and thus can be exploited commercially to broaden the cytoplasmic base of the male-sterile lines and, ultimately, of hybrids.

    The practice of hybridization has greatly contributed to the increase in crop productivity. A major component that exploits heterosis in crops is the cytoplasmic male sterility (CMS)/nucleus-controlled fertility restoration (Rf) system. Through positional cloning, it is shown that heterozygous alleles (RsRf3-1/RsRf3-2) encoding pentatricopeptide repeat (PPR) proteins are responsible for restoring fertility to cytoplasmic male-sterile radish (Raphanus sativus L.). Furthermore, it was found tha...

  7. The genetic and molecular basis of cytoplasmic male sterility and fertility restoration in rice

    2009-01-01

    Cytoplasmic male sterility (CMS) is a maternally inherited characteristic found in many (>150) plant species. CMS/restoration systems are useful tools for hybrid seed production, and are ideal models for study of the interactions between nuclear and mitochondrial genomes. CMS/restoration systems in rice have been widely used for hybrid seed production, greatly contributing to the food supply.

  9. Relationship between ethylene and the occurrence of cytoplasmic male sterility in rice

    2000-01-01

    @@ It was found that exogenous ethylene or ethrel could induce rice male sterility and endogenous ethylene was negatively correlated with pollen fertility and play a key role in the occurrence of rice male sterility. However, it is unknown whether ethylene is related to the occurrence of CMS (cytoplasmic male sterility). In this study, a field experiment was conducted in Guangzhou, using CMS line Zhenshan 97A and its maintainer line Zhenshan 97B.

    Exploitation of novel cytoplasmic male sterility(CMS)is a main approach for widening the cytoplasmic genetic background of hybrid oilseed rape and avoiding epidemic risk in oilseed rape production.In this study,symmetric somatic hybrids between Brassicanapus var.Zhongshuang4 and Sinapis arvensis(Yeyou18)were produced by protoplast fusion.Two of the six established hybrids were male sterile showing trace or no pollen release upon flowering with non-or slightly extended stamens.Using Zhongshuang4 as a recurrent parent to pollinate the male sterile plants,the ratio of male sterile plants increased with the number of backcrosses.As early as in BC3 generation,most of the sterile families had nearly 100%sterile plants.Up to BC4 generation,the male sterility became stable and no fertility segregation was observed.All F1 progenies from tested crosses using restorer and maintainer lines of Polima CMS were 100%sterile,indicating that the established CMS by somatic hybridization is different from Polima CMS.The origin of the cytoplasm and potential use of this hovel CMS in oilseed rape breeding were discussed.Key wotds:Oilseed rape,Protoplast fusion,Cytoplasmic male sterility,Sinapis arvensis

    通过对核质互作型雄性不育系169A和核雄性不育两用系88_3的细胞形态解剖学观察表明,两个不育系在开花时雄性细胞均表现100%的败育,花药的表皮细胞均具有生活力,但败育形式、时期、特点各异。169A败育发生于孢原细胞前后,以孢原细胞退化,或转变成薄壁细胞为主要特点。88_3败育从小孢子母细胞至二核花粉粒皆有发生,高峰期在四分体前后(约占80%),小孢子母细胞不能进入减数分裂和不能完成减数分裂及小孢子不能正常发育是败育的主要形式,但败育特点均是败育一旦发生便是急剧而彻底的解体或凝集成一团。%The morphological anatomical characters of the anthers from nucleo-cytoplasmic interaction male sterile line 169A and genic male sterile line 88-3 were observed. The results showed that the epidermal cells of the anther had viability,while the male sex cell of the two sterile lines appeared 100% abortion at blooming date, however,their abortion form,duration and characters were different.The abortion of 169A occurred before to behind of the sporogonia,whose important characterization was that the sporogonia degenerated or transformed into the parenchyma cells. The abortion of 88-3 ocurred from the microspore mother cells to pollen grains of two-nucleus,while the high peak stage of abortion(80%) occurred before and after the tetrad phase. The main abortion forms of 88-3 were that the microspore mother cells were not able to enter meiosis process and to finish meiosis,and the microspores were not able to develop normally.The same abortion character of the two male sterile lines was that the microspore mother cells and microspores sharply and thoroughly disintegrated or aggregated when abortion occurred.

    Full Text Available Plants of the genus Brassica comprise a remarkably diverse group of crops and encompass varieties that are grown as oilseeds, vegetables, condiment mustards and forages. One of the basic requirements for developing hybrid varieties in oilseed Brassica is the availability of proven heterosis. The development of hybrid cultivars has been successful in many Brassica spp. Midparent heterosis and high-parent heterosis (heterobeltiosis have extensively been explored and utilized for boosting various quantity and quality traits in rapeseed. Heterosis is commercially exploited in rapeseed and its potential use has been demonstrated in turnip rape (B. rapa L. and Indian mustard (B. juncea L. for seed yield and most of the agronomic traits. The oilseed rape plant, B. napus, possesses two endogenous male sterile cytoplasms, nap and pol. Ogura type of cytoplasmic male sterility was first discovered in Japanese wild radish and other male-sterile Brassicas (Ogura bearing cytoplasm derived from interspecific crosses. Information concerning the allelic frequencies of restorers can be useful in trying to understand their evolutionary origins. The ogu, pol and nap cytoplasms of B. napus induce sterility in all, some, and only a few cultivars, respectively. In this study, different kinds of male sterility, combining ability and heterosis of qualitative and quantitative traits in different Brassica species will be reviеwed.

  1. Transcriptome sequencing and de novo analysis of a cytoplasmic male sterile line and its near-isogenic restorer line in chili pepper (Capsicum annuum L..

    Chen Liu

    Full Text Available BACKGROUND: The use of cytoplasmic male sterility (CMS in F1 hybrid seed production of chili pepper is increasingly popular. However, the molecular mechanisms of cytoplasmic male sterility and fertility restoration remain poorly understood due to limited transcriptomic and genomic data. Therefore, we analyzed the difference between a CMS line 121A and its near-isogenic restorer line 121C in transcriptome level using next generation sequencing technology (NGS, aiming to find out critical genes and pathways associated with the male sterility. RESULTS: We generated approximately 53 million sequencing reads and assembled de novo, yielding 85,144 high quality unigenes with an average length of 643 bp. Among these unigenes, 27,191 were identified as putative homologs of annotated sequences in the public protein databases, 4,326 and 7,061 unigenes were found to be highly abundant in lines 121A and 121C, respectively. Many of the differentially expressed unigenes represent a set of potential candidate genes associated with the formation or abortion of pollen. CONCLUSIONS: Our study profiled anther transcriptomes of a chili pepper CMS line and its restorer line. The results shed the lights on the occurrence and recovery of the disturbances in nuclear-mitochondrial interaction and provide clues for further investigations.

    2015-03-01

    Heritable phenotypic alterations occurring during plant ontogenesis under the influence of environmental factors are among the most intriguing genetic phenomena. It was found that male-sterile sorghum hybrids in the 9E cytoplasm from the F1 and F2 generations, which were obtained by crossing CMS lines with different fertile lines grown in field conditions, were transferred to greenhouse produce fertile tillers. Lines created by the self-pollination of revertant tillers exhibit complete male fertility upon cultivation under various environments (in the field, Tdry plot,(y) Tirrigated plot(y)). In a number of test-crosses of revertants to CMS lines in the 9E cytoplasm, restoration of male fertility in F1 hybrids was found, indicating that revertants possess functional fertility-restoring genes. A high positive correlation was found between the fertility level of the test-cross hybrids and the hydrothermal coefficient (the ratio of the sum of precipitation to the sum of temperatures) during the booting stage and pollen maturation (r = 0.75...0.91; Psorghum hybrids in the 9E cytoplasm. These data demonstrate that methylation of nuclear genes in sterility-inducing cytoplasm may be one of mechanisms causing the CMS phenomenon. PMID:26027370

  3. Wolbachia-induced cytoplasmic incompatibility is associated with decreased Hira expression in male Drosophila.

    Ya Zheng

    Full Text Available BACKGROUND: Wolbachia are obligate endosymbiotic bacteria that infect numerous species of arthropods and nematodes. Wolbachia can induce several reproductive phenotypes in their insect hosts including feminization, male-killing, parthenogenesis and cytoplasmic incompatibility (CI. CI is the most common phenotype and occurs when Wolbachia-infected males mate with uninfected females resulting in no or very low numbers of viable offspring. However, matings between males and females infected with the same strain of Wolbachia result in viable progeny. Despite substantial scientific effort, the molecular mechanisms underlying CI are currently unknown. METHODOLOGY/PRINCIPAL FINDINGS: Gene expression studies were undertaken in Drosophila melanogaster and D. simulans which display differential levels of CI using quantitative RT-PCR. We show that Hira expression is correlated with the induction of CI and occurs in a sex-specific manner. Hira expression is significantly lower in males which induce strong CI when compared to males inducing no CI or Wolbachia-uninfected males. A reduction in Hira expression is also observed in 1-day-old males that induce stronger CI compared to 5-day-old males that induce weak or no CI. In addition, Hira mutated D. melanogaster males mated to uninfected females result in significantly decreased hatch rates comparing with uninfected crosses. Interestingly, wMel-infected females may rescue the hatch rates. An obvious CI phenotype with chromatin bridges are observed in the early embryo resulting from Hira mutant fertilization, which strongly mimics the defects associated with CI. CONCLUSIONS/SIGNIFICANCE: Our results suggest Wolbachia-induced CI in Drosophila occurs due to a reduction in Hira expression in Wolbachia-infected males leading to detrimental effects on sperm fertility resulting in embryo lethality. These results may help determine the underlying mechanism of CI and provide further insight in to the important role

    2013-11-01

    Full Text Available Cytoplasmic male sterility (CMS, widely used in the production of hybrid seeds, is a maternally inherited trait resulting in a failure to produce functional pollen. In order to identify some specific proteins associated with CMS in pepper, two-dimensional gel electrophoresis (2-DE was applied to proteomic analysis of anthers/buds between a CMS line (designated NA3 and its maintainer (designated NB3 in Capsicum annuum L. Thirty-three spots showed more than 1.5-fold in either CMS or its maintainer. Based on mass spectrometry, 27 spots representing 23 distinct proteins in these 33 spots were identified. Proteins down-regulated in CMS anthers/buds includes ATP synthase D chain, formate dehydrogenase, alpha-mannosidas, RuBisCO large subunit-binding protein subunit beta, chloroplast manganese stabilizing protein-II, glutathione S-transferase, adenosine kinase isoform 1T-like protein, putative DNA repair protein RAD23-4, putative caffeoyl-CoA 3-O-methyltransferase, glutamine synthetase (GS, annexin Cap32, glutelin, allene oxide cyclase, etc. In CMS anthers/buds, polyphenol oxidase, ATP synthase subunit beta, and actin are up-regulated. It was predicted that male sterility in NA3 might be related to energy metabolism turbulence, excessive ethylene synthesis, and suffocation of starch synthesis. The present study lays a foundation for future investigations of gene functions associated with pollen development and cytoplasmic male sterility, and explores the molecular mechanism of CMS in pepper.

    2016-07-01

    To uncover the cytoplasmic male sterility (CMS)-associated mitochondrial genes of tobacco (Nicotiana tabacum), we determined the complete nucleotide sequence of Sua-CMS mitochondrial genome. The Sua-CMS mtDNA sequence is 522,731 bp in length and contains 34 protein-coding genes, 25 transfer RNA (tRNA) genes, and three ribosomal RNA (rRNA) genes. The nucleotide sequence data of 34 protein-coding genes of 14 mitochondrial genomes were used for constructing the phylogenetic tree. The results showed that Nicotiana tabacum Sua-CMS exhibits most close relationship with other solanaceae species. PMID:27158790

  7. Transcriptome sequencing and de novo analysis of cytoplasmic male sterility and maintenance in JA-CMS cotton.

    Peng Yang

    Full Text Available Cytoplasmic male sterility (CMS is the failure to produce functional pollen, which is inherited maternally. And it is known that anther development is modulated through complicated interactions between nuclear and mitochondrial genes in sporophytic and gametophytic tissues. However, an unbiased transcriptome sequencing analysis of CMS in cotton is currently lacking in the literature. This study compared differentially expressed (DE genes of floral buds at the sporogenous cells stage (SS and microsporocyte stage (MS (the two most important stages for pollen abortion in JA-CMS between JA-CMS and its fertile maintainer line JB cotton plants, using the Illumina HiSeq 2000 sequencing platform. A total of 709 (1.8% DE genes including 293 up-regulated and 416 down-regulated genes were identified in JA-CMS line comparing with its maintainer line at the SS stage, and 644 (1.6% DE genes with 263 up-regulated and 381 down-regulated genes were detected at the MS stage. By comparing the two stages in the same material, there were 8 up-regulated and 9 down-regulated DE genes in JA-CMS line and 29 up-regulated and 9 down-regulated DE genes in JB maintainer line at the MS stage. Quantitative RT-PCR was used to validate 7 randomly selected DE genes. Bioinformatics analysis revealed that genes involved in reduction-oxidation reactions and alpha-linolenic acid metabolism were down-regulated, while genes pertaining to photosynthesis and flavonoid biosynthesis were up-regulated in JA-CMS floral buds compared with their JB counterparts at the SS and/or MS stages. All these four biological processes play important roles in reactive oxygen species (ROS homeostasis, which may be an important factor contributing to the sterile trait of JA-CMS. Further experiments are warranted to elucidate molecular mechanisms of these genes that lead to CMS.

  8. Isolation and genetic characterization of a fertility-restoring revertant induced from cytoplasmic male sterile rice

    A male fertile revertant was isolated from M1 of a cytoplasmic male sterile indica rice line II-32A, the dry seeds of which were treated with 60Co-γ rays at a dose of 290 Gy. The acquired revertant T24 was morphologically and agronomically similar to II-32B, the maintainer of II-32A. Testcrosses of the revertant with II-32A and Zhenshan 97A showed that the revertant was able to restore the fertility of CMS lines. Genetic analysis of the progenies between T24 and II-32A, Zhenshan 97A XieqingzaoA and DZhenshan 97A, which have different cytoplasms, showed that the fertility restoration of four CMS lines by T24 involved one nuclear gene, indicating that T24 was a result of the mutation of one nuclear gene. The mechanism of the restoration of CMS line by T24 was obviously different from other restorers such as Minghui 63 and 20964, which were shown to behave in two gene mode in fertility restoration. The discovery of the revertant T24 contributes to the understanding of CMS and fertility restoration of CMS in rice. The T24 and its parent II-32A may constitute a pair of near isogenic lines for the restoring gene, which should be valuable materials for molecular genetic analysis of CMS

    2007-08-01

    A cytoplasmic male sterile (CMS) line of Brassica juncea was derived by repeated backcrossing of the somatic hybrid (Diplotaxis catholica + B. juncea) to B. juncea. The new CMS line is comparable to euplasmic lines for almost all characters, except for flowers which bear slender, needle-like anthers with aborted pollen. Detailed Southern analysis revealed two copies of coxI gene in the CMS line. One copy, coxI-1 is similar to the coxI gene of B. juncea, whereas the second copy, coxI-2 is present in a novel rearranged region. Northern analysis with eight mitochondrial gene probes showed altered transcript pattern only for the coxI gene. Two transcripts of 2.0 and 2.4 kb, respectively, were detected in the CMS line. The novel 2.4 kb transcript was present in floral bud tissue but absent in the leaf tissue. In plants where male sterility broke down under high temperature during the later part of the growing season, the 2.4 kb coxI transcript was absent, which suggested its association with the CMS. The two coxI genes from the CMS line showed two amino acid changes in the coding region. The novel coxI gene showed unique repeats in the 5′ region suggesting recombination of mitochondrial genomes of the two species. The possible role of the duplicated coxI gene in causing male sterility is discussed.

    Fang, Xianping; Fu, Hong-Fei; Gong, Zhen-Hui; Chai, Wei-Guo

    2016-01-01

    To explore the mechanisms of pepper (Capsicum annuum L.) cytoplasmic male sterility (CMS), we studied the different maturation processes of sterile and fertile pepper anthers. A paraffin section analysis of the sterile anthers indicated an abnormality of the tapetal layer and an over-vacuolization of the cells. The quantitative proteomics results showed that the expression of histidinol dehydrogenase (HDH), dihydroxy-acid dehydratase (DAD), aspartate aminotransferase (ATAAT), cysteine synthase (CS), delta-1-pyrroline-5-carboxylate synthase (P5CS), and glutamate synthetase (GS) in the amino acid synthesis pathway decreased by more than 1.5-fold. Furthermore, the mRNA and protein expression levels of DAD, ATAAT, CS and P5CS showed a 2- to 16-fold increase in the maintainer line anthers. We also found that most of the amino acid content levels decreased to varying degrees during the anther tapetum period of the sterile line, whereas these levels increased in the maintainer line. The results of our study indicate that during pepper anther development, changes in amino acid synthesis are significant and accompany abnormal tapetum maturity, which is most likely an important cause of male sterility in pepper.

  14. Somatic hybrids between Arabidopsis thaliana and cytoplasmic male-sterile radish (Raphanus sativus).

    Yamagishi, H; Glimelius, K

    2003-08-01

    Somatic hybrids were produced by protoplast fusion between Arabidopsis thaliana ecotype Columbia and a male-sterile radish line MS-Gensuke ( Raphanus sativus) with the Ogura cytoplasm. Forty-one shoots were differentiated from the regenerated calli and established as shoot cultures in vitro. About 20 of these shoots were judged to be hybrids based on growth characteristics and morphology. Molecular analyses of 11 shoots were performed, confirming the hybrid features. Of these 11 shoots, eight were established as rooted plants in the greenhouse. Polymerase chain reaction and randomly amplified polymorphic DNA analyses of the nuclear genomes of all analyzed shoots and plants confirmed that they contained hybrid DNA patterns. Their chromosome numbers also supported the hybrid nature of the plants. Investigations of the organelles in the hybrids revealed that the chloroplast (cp) genome was exclusively represented by radish cpDNA, while the mitochondrial DNA configuration showed a combination of both parental genomes as well as fragments unique to the hybrids. Hybrid plants that flowered were male-sterile independent of the presence of the Ogura CMS-gene orf138. PMID:12827437

    Radish cytoplasmic male sterility (CMS) has been widely used for breeding in Raphanus and Brassica genera. However, the detailed regulation network of the male sterility remains to be determined. Our previous work has shown that the abnormalities in a CMS radish appeared shortly after the tetrad stage when microspores were malformed and the tapetal cells grew abnormally large. In this work, histological analysis shows that anthers are at the tetrad stage when the radish buds are about 1.5 mm ...

  17. Reduced activity of ATP synthase in mitochondria causes cytoplasmic male sterility in chili pepper.

    Li, Jinjie; Pandeya, Devendra; Jo, Yeong Deuk; Liu, Wing Yee; Kang, Byoung-Cheorl

    2013-04-01

    Cytoplasmic male sterility (CMS) is a maternally inherited trait characterized by the inability to produce functional pollen. The CMS-associated protein Orf507 (reported as Orf456 in previous researches) was previously identified as a candidate gene for mediating male sterility in pepper. Here, we performed yeast two-hybrid analysis to screen for interacting proteins, and found that the ATP synthase 6 kDa subunit containing a mitochondrial signal peptide (MtATP6) specifically interacted with Orf507. In addition, the two proteins were found to be interacted in vivo using bimolecular fluorescence complementation (BiFC) and co-immunoprecipitation (Co-IP) assays. Further functional characterization of Orf507 revealed that the encoded protein is toxic to bacterial cells. Analysis of tissue-specific expression of ATP synthase 6 kDa showed that the transcription level was much lower in anthers of the CMS line than in their wild type counterparts. In CMS plants, ATP synthase activity and content were reduced by more than half compared to that of the normal plants. Taken together, it can be concluded that reduced ATP synthase activity and ATP content might have affected pollen development in CMS plants. Here, we hypothesize that Orf507 might cause MtATP6 to be nonfunctional by changing the latter's conformation or producing an inhibitor that prevents the normal functioning of MtATP6. Thus, further functional analysis of mitochondrial Orf507 will provide insights into the mechanisms underlying CMS in plants. PMID:23274393

  18. Pollen mitochondria in cytoplasmically male sterile tobacco zygotic and embryonic cells

    An attempt is being made to establish cytoplasmic organelles transmission during the process of fertilization, by using tobacco grain pollen labelled with leucine 14C and tritiated thymidine. Through autoradiography the fate of pollen germination and its entry into the embryo sac has been studied. A few days after fertilization, labelled cytoplasmic organelles - mainly mitochondria - were detected in the embryo sac. However, labelling was not observed in cytoplasmic organelles by using tritiated thymidine. For more conclusive results labelled DNA incorporated in cytoplasmic organelles have to be traced during the embryo and endosperm development

  19. Male Factors and socioeconomic indicators correlate with the risk of spontaneous abortion

    Olsen, Jørn; Basso, Olga; Christensen, Kaare

    1999-01-01

    No less than 10% of clinically recognised pregnancies end as spontaneous abortions and the recurrence risk is high. Due to lack of data and appropriate study design only little is known about preventable causes of miscarriage. The aim of this study was to estimate the effect of paternal and...... personal identification numbers and information stored in several population registers. Change of partner reduced the recurrence risk of spontaneous abortion substantially (OR = 0.59; 95 CI 0.52-0.67), but also changes in social status or job reduced the recurrence risk significantly.

    We previously discovered carpelloid stamens when breeding cytoplasmic male sterile lines in broccoli (Brassica oleracea var. italica). In this study, hybrids and multiple backcrosses were produced from different cytoplasmic male sterile carpelloid stamen sources and maintainer lines. Carpelloid stamens caused dysplasia of the flower structure and led to hooked or coiled siliques with poor seed setting, which were inherited in a maternal fashion. Using four distinct carpelloid stamens and twelve distinct normal stamens from cytoplasmic male sterile sources and one maintainer, we used 21 mitochondrial simple sequence repeat (mtSSR) primers and 32 chloroplast SSR primers to identify a mitochondrial marker, mtSSR2, that can differentiate between the cytoplasm of carpelloid and normal stamens. Thereafter, mtSSR2 was used to identify another 34 broccoli accessions, with an accuracy rate of 100%. Analysis of the polymorphic sequences revealed that the mtSSR2 open reading frame of carpelloid stamen sterile sources had a deletion of 51 bases (encoding 18 amino acids) compared with normal stamen materials. The open reading frame is located in the coding region of orf125 and orf108 of the mitochondrial genomes in Brassica crops and had the highest similarity with Raphanus sativus and Brassica carinata. The current study has not only identified a useful molecular marker to detect the cytoplasm of carpelloid stamens during broccoli breeding, but it also provides evidence that the mitochondrial genome is maternally inherited and provides a basis for studying the effect of the cytoplasm on flower organ development in plants.

    2009-01-01

    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.

    Cytoplasmic male sterility (CMS) is the failure to produce functional pollen, which is inherited maternally. And it is known that anther development is modulated through complicated interactions between nuclear and mitochondrial genes in sporophytic and gametophytic tissues. However, an unbiased transcriptome sequencing analysis of CMS in cotton is currently lacking in the literature. This study compared differentially expressed (DE) genes of floral buds at the sporogenous cells stage (SS) an...

    In sunflower plants carrying the PET1 cytoplasm male sterility (CMS) is associated with a new open reading frame (orfH522) in the 3'-flanking region of the atpA gene and an additional 16 kDa protein. Twenty-seven male-sterile cytoplasms of different origin were studied for the expression of the 16 kDa protein. In addition to the PET1 cytoplasm nine other male-sterile cytoplasms express the CMS-associated protein. These CMS sources originate from different interspecific crosses, from spontaneously occurring male-sterile plants in wild sunflower and from induced mutagenesis. Polyclonal antisera were raised against fusion proteins which contain 421 bp of the 3'-coding region of orfH522 to verify by immunological methods the identity of the other CMS cytoplasms. The anti-ORFH522 antiserum showed a positive reaction in the immunoblot with all CMS cytoplasms which expressing the 16 kDa protein. Investigations of the mitochondrial DNA demonstrated that all ten CMS cytoplasms which express the 16 kDa protein have the same organization at the atpA locus. OrfH522 as probes gave the same transcript pattern for the investigated CMS cytoplasms, just as for PET1. The MAX1 cytoplasm has an orfH522-related sequence but does not synthesize the 16 kDa protein. Using the sodium carbonate treatment the 16 kDa protein proved to be membrane-bound. Computer analyses predict that the hydrophobic N-terminal region of ORFH522 may form a transmembrane helix functioning as membrane anchor. PMID:8605303

    2012-07-01

    Full Text Available Abstract Background Plant mitochondrial genome has unique features such as large size, frequent recombination and incorporation of foreign DNA. Cytoplasmic male sterility (CMS is caused by rearrangement of the mitochondrial genome, and a novel chimeric open reading frame (ORF created by shuffling of endogenous sequences is often responsible for CMS. The Ogura-type male-sterile cytoplasm is one of the most extensively studied cytoplasms in Brassicaceae. Although the gene orf138 has been isolated as a determinant of Ogura-type CMS, no homologous sequence to orf138 has been found in public databases. Therefore, how orf138 sequence was created is a mystery. In this study, we determined the complete nucleotide sequence of two radish mitochondrial genomes, namely, Ogura- and normal-type genomes, and analyzed them to reveal the origin of the gene orf138. Results Ogura- and normal-type mitochondrial genomes were assembled to 258,426-bp and 244,036-bp circular sequences, respectively. Normal-type mitochondrial genome contained 33 protein-coding and three rRNA genes, which are well conserved with the reported mitochondrial genome of rapeseed. Ogura-type genomes contained same genes and additional atp9. As for tRNA, normal-type contained 17 tRNAs, while Ogura-type contained 17 tRNAs and one additional trnfM. The gene orf138 was specific to Ogura-type mitochondrial genome, and no sequence homologous to it was found in normal-type genome. Comparative analysis of the two genomes revealed that radish mitochondrial genome consists of 11 syntenic regions (length >3 kb, similarity >99.9%. It was shown that short repeats and overlapped repeats present in the edge of syntenic regions were involved in recombination events during evolution to interconvert two types of mitochondrial genome. Ogura-type mitochondrial genome has four unique regions (2,803 bp, 1,601 bp, 451 bp and 15,255 bp in size that are non-syntenic to normal-type genome, and the gene orf138

    Background The use of cytoplasmic male sterility (CMS) in F1 hybrid seed production of chili pepper is increasingly popular. However, the molecular mechanisms of cytoplasmic male sterility and fertility restoration remain poorly understood due to limited transcriptomic and genomic data.

    2012-01-01

    To investigate the spatial-temporal patterns and other characteristics of anther abortion in 0912A as a leaf mustard cytoplasmic male sterile line and its maintainer line 0912B,cytological observations of anther development were made by means of paraffin sections. The results showed that the abortion of male sterile line was diverse. The abortion mainly occurred at the differentiation stage of arches-porial cell, which lacked the formation of pollen sacs. Part of anther abortion occurred at the period from pollen mother cell to the mono-nuclear microspore: some pollen mother cells gathered and disintegrated gradually after vacuolization; some pollen mother cells disintegrated due to the hypertrophy of tapetal layer cells in the radial direction; some pollen mother cells could develop to tetrad, then disintegrated; part of the pollen mother cells could develop to the mono-nucleus microspores, however the mono-nucleus microspores broke when they were highly vacuolated. The stamens of 0912A were also found to degenerate as abortive filaments.%采用石蜡切片方法,对叶用芥菜细胞质雄性不育系0912A及其保持系0912B的花药发育过程进行细胞学观察,以确定其花药败育的时期、方式和特点.结果表明:0912A不育系的败育形式多样,主要有花药发育受阻于孢原细胞分化期,无花粉囊的形成;部分花药在花粉母细胞期至单核小孢子期出现发育异常:有的花粉母细胞液泡化后浓缩解体,还有的花粉母细胞因绒毡层细胞径向肥大或液泡化而受挤压解体;有的花粉母细胞虽能进行减数分裂,但发育到四分体时期或单核时期细胞解体,花粉败育.同时对0912A的花器官形态进行观察,发现其雄蕊退化为细丝状,败育彻底.

  8. Cytological observations on microspore degeneration in cytoplasmic male sterility induced by gamma-irradiation in sugar beets

    Meiotic behaviours and the abnormalities of microsporogenesis were investigated in the complete sterile plants from four kinds of γ-line, which are the progenies of the male sterile mutants induced by γ-irradiations from H-2002, and these sterile plants were compared with those of H-19 MS with S cytoplasms in spontaneous origin. In the meiosis, there was no chromosomal abnormality showing the association of nine bivalents and the regular distribution of chromosomes irrespective of the source of cytoplasms. After the liberation of quartets, the conspicuous deformity of tapetal cells occurred in the complete sterile plants throughout all kinds of γ-line and H-19 MS. The modified type of anther tapeta was newly found in several plants from γ-114. The tapetal cells surrounding anther cavity enlarged vadially without the formation of tapetal plasmodium in this type. It is suggested that the different mechanism on pollen sterility has something to do with the cytoplasmic types which are responsible for the expression of complete sterile plants. The starch reaction in the middle layer and the endothecium of the anther also correlated with the type of tapetal abnormality. (Kobatake, H.)

  12. Discovery of mitochondrial chimeric-gene associated with cytoplasmic male sterility of HL-rice

    2002-01-01

    The mitochondrial genome libraries of HL-type sterile line(A) and maintainer line(B) have been constructed.Mitochondrial gene, atp6, was used to screen libraries, due to the different Southern and Northern blot results between sterile and maintainer line. Sequencing analysis of positive clones proved that there were two copies of atp6 gene in sterile line and only one in maintainer line. One copy of atpt6 in sterile line was same to that in maintainer line; the other showed different flanking sequence from the 49th nucleotide downstream of the termination codon of atp6 gene. A new chimeric gene, orfH79, was found in the region. OrfH79 had homology to mitochondrial gene coxⅡ and orfl07, and was special to HL-sterile cytoplasm.``

  13. Ultra structure of wheat hybrid of cytoplasmic male sterile lines by irradiation

    Hybrids F1 of restores lines BPM15 and Yuanhui 3 crossed with CMS lines 85EA, 89 AR and TA were observed on the ultra structure of microspore at various developmental stage respectively. The main results showed as follows. At mono-nucleus microspore stage, cytoplasm were thick and organella, such as mitochondria, endoplasmic reticulum were abundant. At two-nucleus and three-nucleus stage, there were a lot of starch grains. In the CMS hybrid F1 of BPM15 and Yuanhui 3 crossed with 85EA and 89AR, there were more endoplasmic reticulum and ribosome at mono-nucleus microspore stage, which might be one of the causes that fertility of 85EA and 89AR were easier to restore than Tcms

    Male sterile NEA plants were identified in progenies of the radiated 92P×Aggregate-silique in Brassica napus L. In 1993. Their progeny plants from test crossing and open pollination were 100% male sterile. The double-low male sterile lines JL-4 and JL-18 were bred through successive backcrossing of the double -low variety No. 4 and No. 18 in Brassica napus L. To NEA. Restorer lines 6720 and 6722 with significant heterosis in F1 were developed. The results from investigating the restoring-maintaining relationship and inheritance of the restorer gene indicated that JL-4 and JL-18 were different from both PolCMS and Shan 2A type,and their restorer gene was controlled by a pair of dominant genic genes.

  16. The transfer of 'Polima' cytoplasmic male sterility from oilseed rape (Brassica napus) to broccoli (B. oleracea) by protoplast fusion.

    Yarrow, S A; Burnett, L A; Wildeman, R P; Kemble, R J

    1990-08-01

    Protoplast fusion was utilised to transfer Polima type cytoplasmic male sterility (CMS) from Brassica napus, canola cv. Polima Karat (Pol-Karat) to B. oleracea, broccoli, var. "Green Comet". Southern and RFLP analysis confirmed that four cybrids possessed nuclear genomes of broccoli with Polima mitochondria and chloroplasts. A fifth cybrid was a nuclear hybrid between broccoli and Pol-Karat, with Polima mitochondria and chloroplasts of broccoli. The broccoli type cybrids were morphologically similar to "Green Comet", while the hybrid type was an intermediate of the two fusion parents. Flowers on the cybrids were distinctive in that although they possessed a morphology typical of Polima, they had very reduced petals. The broccoli type cybrids exhibited some female fertility, albeit low, establishing potential for F1 hybrid production. PMID:24226699

    Cytoplasmic male sterility (CMS) is a maternally inherited trait producing abnormal pollen during anther development. To identify the critical genes and pathways that are involved in the sterility and to better understand the underlying mechanisms, cabbage anthers at different developmental stages were cytologically examined and the transcriptomes were analyzed in CMS line and its maintainer line using the next-generation sequencing (NGS) technology. Microscopy showed that anther development in the CMS line was abnormal in the tetrad stage and failed to produce fertile pollen. We obtained 55,663,594 and 54,801,384 raw transcriptome reads from the sterile and maintainer lines, respectively, and assembled these reads into 68,851 unigenes with an average size of 1028 bp. By using the fragments assigned per kilobase of target per million mapped reads (FPKM) method, 5592 differentially expressed genes were identified, consisting of 3403 up- and 2089 down-regulated genes. Furthermore, there were 1011 and 45 genes specifically expressed in the maintainer or sterile line, respectively. Gene Ontology (GO) functional annotation and enrichment analysis of metabolic pathways were performed to map and analyze the candidate genes that may be involved in male sterility. Expression of eighteen genes was examined using qRT-PCR and their expression patterns were found to be same as the sequencing data. A clear cytological difference exists between the sterile and maintainer lines. The differentially expressed genes are associated with carbohydrate and energy metabolisms, or encode transcription factors, heat shock proteins and other stress proteins. Identification of these candidate genes provides a comprehensive understanding of the mechanism underlying CMS in cabbage. PMID:27116370

  19. Mapping of Rice Fertility-Restoring Genes for ID-Type Cytoplasmic Male Sterility in a Restorer Line R68

    2008-01-01

    An F2 population derived from the cross Zhong 9NR68 was used to map the fertility-restoring (Rf) gene for ID-type cytoplasmic male sterility (CMS).Two bulks (a fertile bulk and a sterile bulk) were constructed by pooling equal amount of ten highly fertile lines and ten highly sterile lines,respectively.Four hundred and thirteen pairs of simple sequence repeat (SSR) primers,which evenly distributed on 12 chromosomes of rice,were selected for analyzing polymorphisms between the parents and between the two bulks.The primer RM283 on chromosome 1 and the primers RM5756,RM258,RM6100 and RM171 on chromosome 10 were found to be polymorphic between the parents and between the two bulks.These five SSR markers were linked to fertility-restoring genes.A total of 82 excessive sterile lines were selected from Zhong 9NR68 F2 population to estimate the genetic distance between five SSR markers and fertility-restoring genes respectively.The results indicated that one Rf gene was linked to RM283 located on chromosome 1 at a distance of 6.7 cM,and the other Rfgene was mapped to the long arm of chromosome 10 flanked by RM258 and RM6100 at the distances of 8.0 cM and 2.4 cM,respectively.

  20. Heritable effect of plant water availability conditions on restoration of male fertility in the ‘9E’ CMS-inducing cytoplasm of sorghum

    Lev Aleksandrovich Elkonin

    2012-05-01

    Full Text Available Heritable changes of phenotype arising in plant ontogenesis by the influence of environmental factors belong to the most intriguing genetic phenomena. Studying restoration of male fertility in the ‘9E’ type of CMS-inducing cytoplasm of sorghum and related CMS-inducing cytoplasms, A4 and M35-1A, in some hybrid combinations, we found an unusual inheritance pattern: the Rf-genes functioned in the self-pollinated progenies of F1 hybrids (up to F10 but did not or poorly expressed in backcrosses of these hybrids to CMS-lines with the same cytoplasm type. In experiments on parallel growing of the same F1 hybrid combinations in the ‘dry plot’ and in the ‘irrigated plot’, it was found that high level of plant water availability during panicle and pollen developmental stages significantly increased male fertility of F1 and testcross hybrid populations, in which fertility-restoring genes were in heterozygote state, whereas in F2 populations the influences of water availability conditions cause less pronounce effects. Similarly, male-sterile F1 plants, being transferred from the ‘dry plot’ to greenhouse, produced male-fertile panicles. In addition, male-sterile plants from F2 families, which segregated-out as recessives, being transferred to greenhouse also produced male-fertile panicles. In the progenies of these revertants that were grown in field conditions and in the ‘dry plot’, stable inheritance of male fertility for 3 cycles of self-pollination was observed, and a number of stable fertile lines in the ‘9E’ cytoplasm were obtained. However, in test-crosses of these fertile lines to CMS-lines with the ‘9E’ cytoplasm restoration of male fertility was not observed, except the progeny of one revertant that behaved as fertility-restorer line. These data suggest that the functional state of fertility-restoring genes for the ‘9E’ sorghum cytoplasm is epigenetically-regulated trait established by the influence of environmental

  1. Comparative analysis of mitochondrial genomes between a wheat K-type cytoplasmic male sterility (CMS line and its maintainer line

    Liu Dongcheng

    2011-03-01

    Full Text Available Abstract Background Plant mitochondria, semiautonomous organelles that function as manufacturers of cellular ATP, have their own genome that has a slow rate of evolution and rapid rearrangement. Cytoplasmic male sterility (CMS, a common phenotype in higher plants, is closely associated with rearrangements in mitochondrial DNA (mtDNA, and is widely used to produce F1 hybrid seeds in a variety of valuable crop species. Novel chimeric genes deduced from mtDNA rearrangements causing CMS have been identified in several plants, such as rice, sunflower, pepper, and rapeseed, but there are very few reports about mtDNA rearrangements in wheat. In the present work, we describe the mitochondrial genome of a wheat K-type CMS line and compare it with its maintainer line. Results The complete mtDNA sequence of a wheat K-type (with cytoplasm of Aegilops kotschyi CMS line, Ks3, was assembled into a master circle (MC molecule of 647,559 bp and found to harbor 34 known protein-coding genes, three rRNAs (18 S, 26 S, and 5 S rRNAs, and 16 different tRNAs. Compared to our previously published sequence of a K-type maintainer line, Km3, we detected Ks3-specific mtDNA (> 100 bp, 11.38% and repeats (> 100 bp, 29 units as well as genes that are unique to each line: rpl5 was missing in Ks3 and trnH was absent from Km3. We also defined 32 single nucleotide polymorphisms (SNPs in 13 protein-coding, albeit functionally irrelevant, genes, and predicted 22 unique ORFs in Ks3, representing potential candidates for K-type CMS. All these sequence variations are candidates for involvement in CMS. A comparative analysis of the mtDNA of several angiosperms, including those from Ks3, Km3, rice, maize, Arabidopsis thaliana, and rapeseed, showed that non-coding sequences of higher plants had mostly divergent multiple reorganizations during the mtDNA evolution of higher plants. Conclusion The complete mitochondrial genome of the wheat K-type CMS line Ks3 is very different from that of

    2015-07-01

    Genetic conflict between cytoplasmically inherited elements and nuclear genes arising from their different transmission patterns can be seen in cytoplasmic male sterility (CMS), the mitochondrion-encoded inability to shed functional pollen. CMS is associated with a mitochondrial open reading frame (ORF) that is absent from non-sterility inducing mitochondria (S-orf). Nuclear genes that suppress CMS are called restorer-of-fertility (Rf) genes. Post-transcriptional and translational repression of S-orf mediates the molecular action of Rf that encodes a class of RNA-binding proteins with pentatricopeptide repeat (PPR) motifs. Besides the PPR-type of Rfs, there are also non-PPR Rfs, but the molecular interactions between non-PPR Rf and S-orf have not been described. In this study, we investigated the interaction of bvORF20, a non-PPR Rf from sugar beet (Beta vulgaris), with preSatp6, the S-orf from sugar beet. Anthers expressing bvORF20 contained a protein that interacted with preSATP6 protein. Analysis of anthers and transgenic calli expressing a FLAG-tagged bvORF20 suggested the binding of preSATP6 to bvORF20. To see the effect of bvORF20 on preSATP6, which exists as a 250-kDa protein complex in CMS plants, signal bands of preSATP6 in bvORF20-expressing and non-expressing anthers were compared by immunoblotting combined with Blue Native polyacrylamide gel electrophoresis. The signal intensity of the 250-kDa band decreased significantly, and 200- and 150-kDa bands appeared in bvORF20-expressing anthers. Transgenic callus expressing bvORF20 also generated the 200- and 150-kDa bands. The 200-kDa complex is likely to include both preSATP6 and bvORF20. Post-translational interaction between preSATP6 and bvORF20 appears to alter the higher order structure of preSATP6 that may lead to fertility restoration in sugar beet. PMID:26031622

  3. R Region of S Type of Cytoplasmic Male Sterility in Maize Mitochondrial DNA is Transcribed in Both Directions and May Be Associated with Male Sterility

    ZHANGSai-Qun; ZHANGFang-Dong; XIAOHai-Lin; ZHENGYong-Lian

    2004-01-01

    It is well accepted that S type of cytoplasmic male sterility (CMS) in maize (Zea mays L.) isassociated with R region in mitochondrial genome. R region includes two open reading frames——orf355and orf77and it is speculated that orf77is an important candidate gene of CMS. RT-PCR showed that bothDNA strands of R region are transcribed. Nuclear background or developing stages of plant do not influencethe transcription of R region in the strand which also acts as template strand of cox Ⅰ/coxⅡ locating justupstream of R region, but they do influence the transcription of R region in the other strand (templatestrand of orf355-orf77). In tassel with nuclear background of rf3rf3, transcription of the template strand oforf355-orf77 is different from that in etiolated shoots with nuclear background of Rf3- or rf3rf3and tasselwith nuclear background of Rf3-. Compared to the same other three, it is truncated at about 238 base fromthe 5' end of R region. Rabbit antiserum against putative ORF77 expressed in Escherichia coliwas preparedbut Western blot did not detect ORF77 in plant materials. It seems that double-strand transcription of Rregion inhibits the translation of orf77and the transcribing mode of R region may be associated with malesterility.

    Broccoli (Brassica oleracea var. italica) is an important commercial vegetable crop. As part of an efficient pollination system, cytoplasmic male sterility (CMS) has been widely used for broccoli hybrid production. Identifying the original sources of CMS in broccoli accessions has become an important part of broccoli breeding. In this study, the diversity of the CMS sources of 39 broccoli accessions, including 19 CMS lines and 20 hybrids, were analyzed using mitochondrial markers. All CMS accessions contained the ogu orf138-related DNA fragment and the key genes of nap CMS, pol CMS, and tour CMS were not detected. The 39 CMS accessions were divided into five groups using six orf138-related and two simple sequence repeat markers. We observed that ogu CMS R3 constituted 79.49% of the CMS sources. CMS6 and CMS26 were differentiated from the other accessions using a specific primer. CMS32 was distinguished from the other accessions based on a 78-nucleotide deletion at the same locus as the orf138-related sequence. When the coefficient was about 0.90, five CMS accessions (13CMS6, 13CMS23, 13CMS24, 13CMS37, and 13CMS39) exhibiting abnormal floral organs with poor seed setting were grouped together. The polymerase chain reaction amplification profiles for these five accessions differed from those of the other accessions. We identified eight useful molecular markers that can be used to detect CMS types during broccoli breeding. Our data also provide important information relevant to future studies on the possible origins and molecular mechanisms of CMS in broccoli. PMID:27446156

    Full Text Available Plus-hybrid effect refere to a combined effect of cytoplasmic male sterility (CMS and xenia in maize (Zea mays L. It could be used in commercial production by growing a mixture of 80% CMS hybrid and 20% of another fertile hybrid. The aim of this research was to examine individual and combined CMS and xenia effects on two hybrids widely grown in Serbia. Sterile and fertile versions of ZP 1 and ZP 2 hybrids (three-way; Iodent x Lancaster dents were used as females, while ZP 1, ZP 2, ZP 3, ZP 4, and ZP 5 (three-way or single cross; Iodent (BSSS x Lancaster dents were used as pollinators. All of them belong to medium maturity group. The trial was set up at one location in Serbia (Zemun Polje in 2009, 2010, and 2011. Molecular analysis of the five genotypes was done using simple sequence repeat (SSR primers. Plus-hybrid effect on grain yield ranged from -6.2% to 6.2%; on thousand kernel weight from -1.7% to 5.2%; on number of kernels per area from -1.0% to 8.0%. The poor response could be due to a use of three-way instead of single cross hybrids in S type of sterility. Modified Rogers' distance between hybrids was in the range 0.211 to 0.378 and was not relevant for the effect, which depended mostly on the sterile hybrid genotype and the fertile hybrid pollinator ability. This approach should be more suitable for female hybrids with slightly poorer performance, already being produced on a sterile base.

    Broccoli (Brassica oleracea var. italica) is an important commercial vegetable crop. As part of an efficient pollination system, cytoplasmic male sterility (CMS) has been widely used for broccoli hybrid production. Identifying the original sources of CMS in broccoli accessions has become an important part of broccoli breeding. In this study, the diversity of the CMS sources of 39 broccoli accessions, including 19 CMS lines and 20 hybrids, were analyzed using mitochondrial markers. All CMS accessions contained the ogu orf138-related DNA fragment and the key genes of nap CMS, pol CMS, and tour CMS were not detected. The 39 CMS accessions were divided into five groups using six orf138-related and two simple sequence repeat markers. We observed that ogu CMS R3 constituted 79.49% of the CMS sources. CMS6 and CMS26 were differentiated from the other accessions using a specific primer. CMS32 was distinguished from the other accessions based on a 78-nucleotide deletion at the same locus as the orf138-related sequence. When the coefficient was about 0.90, five CMS accessions (13CMS6, 13CMS23, 13CMS24, 13CMS37, and 13CMS39) exhibiting abnormal floral organs with poor seed setting were grouped together. The polymerase chain reaction amplification profiles for these five accessions differed from those of the other accessions. We identified eight useful molecular markers that can be used to detect CMS types during broccoli breeding. Our data also provide important information relevant to future studies on the possible origins and molecular mechanisms of CMS in broccoli. PMID:27446156

    2016-01-01

    Radish cytoplasmic male sterility (CMS) has been widely used for breeding in Raphanus and Brassica genera. However, the detailed regulation network of the male sterility remains to be determined. Our previous work has shown that the abnormalities in a CMS radish appeared shortly after the tetrad stage when microspores were malformed and the tapetal cells grew abnormally large. In this work, histological analysis shows that anthers are at the tetrad stage when the radish buds are about 1.5 mm in length. Furthermore, a high throughput RNA sequencing technology was employed to characterize the transcriptome of radish buds with length about 1.5 mm from two CMS lines possessing the CMS-inducing orf138 gene and corresponding near-isogenic maintainer lines. A total of 67,140 unigenes were functionally annotated. Functional terms for these genes are significantly enriched in 55 Gene Ontology (GO) groups and 323 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. The transcriptome detected transcripts for 72 out of a total of 79 protein genes encoded in the chloroplast genome from radish. In contrast, the radish mitochondrial genome contains 34 protein genes, but only 16 protein transcripts were detected from the transcriptome. The transcriptome comparison between CMS and near-isogenic maintainer lines revealed 539 differentially expressed genes (DEGs), indicating that the false positive rate for comparative transcriptome profiling was clearly decreased using two groups of CMS/maintainer lines with different nuclear background. The level of 127 transcripts was increased and 412 transcripts were decreased in the CMS lines. No change in levels of transcripts except CMS-inducing orf138 was identified from the mitochondrial and chloroplast genomes. Some DEGs which would be associated with the CMS, encoding MYB and bHLH transcription factors, pentatricopeptide repeat (PPR) proteins, heat shock transcription factors (HSFs) and heat shock proteins (HSPs), are discussed.

    Taigu Genic Male Sterile Wheat (TGMSW; Triticum aestivum L.), a dominant genic male sterile germplasm, is of considerable value in the genetic improvement of wheat because of its stable inherence, complete male abortion, and high cross-fertilization rate. To identify specially transcribed genes in sterile anther, a suppression subtractive hybridization (SSH) library was constructed with sterile anther as the tester and fertile anther as the driver. A total of 2 304 SSH inserts amplified by polymerase chain reaction were arrayed using robotic printing. The cDNA arrays were hybridized with 32P-labeled probes prepared from the RNA of forward- and reverse-subtracted anthers. Ninety-six clones were scored as upregulated in sterile anthers compared with the corresponding fertile anthers and some clones were selected for sequencing and analysis in GenBank. Based on their putative functions, 87 non-redundant clones were classified into the following groups: (i) eight genes involved in metabolic processes; (ii) four material transportation genes;(iii) three signal transduction-associated genes; (iv) four stress response and senescence-associated protein genes; (v) seven other functional protein genes; (vi) five genes with no known function; and (vii)another 56 genes with no match to the databases. To test the hybridization efficiency, eight genes were selected and analyzed by Northern blot. The results of the present study provide a comprehensive overview of the genes and gene products involved in anther abortion in TGMSW.

  11. Comparative Transcriptome Analysis between the Cytoplasmic Male Sterile Line NJCMS1A and Its Maintainer NJCMS1B in Soybean (Glycine max (L. Merr..

    Jiajia Li

    Full Text Available The utilization of soybean heterosis is probably one of the potential approaches in future yield breakthrough as was the situation in rice breeding in China. Cytoplasmic male sterility (CMS plays an important role in the production of hybrid seeds. However, the molecular mechanism of CMS in soybean remains unclear.The comparative transcriptome analysis between cytoplasmic male sterile line NJCMS1A and its near-isogenic maintainer NJCMS1B in soybean was conducted using Illumina sequencing technology. A total of 88,643 transcripts were produced in Illumina sequencing. Then 56,044 genes were obtained matching soybean reference genome. Three hundred and sixty five differentially expressed genes (DEGs between NJCMS1A and NJCMS1B were screened by threshold, among which, 339 down-regulated and 26 up-regulated in NJCMS1A compared to in NJCMS1B. Gene Ontology (GO annotation showed that 242 DEGs were annotated to 19 functional categories. Clusters of Orthologous Groups of proteins (COG annotation showed that 265 DEGs were classified into 19 categories. Kyoto Encyclopedia of Genes and Genomes (KEGG analysis showed that 46 DEGs were assigned to 33 metabolic pathways. According to functional and metabolic pathway analysis combined with reported literatures, the relations between some key DEGs and the male sterility of NJCMS1A were discussed. qRT-PCR analysis validated that the gene expression pattern in RNA-Seq was reliable. Finally, enzyme activity assay showed that energy supply was decreased in NJCMS1A compared to in NJCMS1B.We concluded that the male sterility of NJCMS1A might be related to the disturbed functions and metabolism pathways of some key DEGs, such as DEGs involved in carbohydrate and energy metabolism, transcription factors, regulation of pollen development, elimination of reactive oxygen species (ROS, cellular signal transduction, and programmed cell death (PCD etc. Future research will focus on cloning and transgenic function validation of

  12. Influence of Genetic Drift of Restoring Gene (Rf) on Seed Purity of Yuetai A, a Honglian-Type Cytoplasmic Male Sterile Line in Hybrid Rice

    2008-01-01

    The seed samples of Yuetai A,a Honglian (HL) type cytoplasmic male sterile (CMS) line in hybrid rice were investigated to assess the seed purity and to analyze the cause of off-type plants by imitating the biological contaminant to Yuetai A in Nanjing,Jiangsu Province and Lingshui,Hainan Province during 2004-2006.The seed impurity of Yuotai A mainly resulted from the genetic drift of restoring fertility gene (Rt) after biological contamination but not from its sterility unstability.All of the ten maintainer lines,five restorer lines and three thermo-sensitive genic male sterile lines used in the study could pollinate Yuetai A and Yuetai B to produce F1 plants,directly or indirectly resulting in Rf-gene drifting into Yuetai A and generating 'iso-cytoplasm restoring-generations'.Furthermore,high outcrossing rate and similar heading date of Yuetai A with many varieties used in rice production might easily result in the biological contamination.After removing all plants with Rf-gene mixed in Yuetai A and preventing Rf-gene drifting into Yuetai A,the seed purity of Yuetai A and Yuetai B had been raised to 100%.

    We have previously reported correction of severe leaf chlorosis in the cytoplasmic male sterile Ogura (also called Ogu) Brassica juncea line carrying Ogura cytoplasm by plastid substitution via protoplast fusion. Two cybrids obtained from the fusion experiment, Og1 and Og2, were green and carried the plastid genome of B. juncea cv. RLM198. While Og1 displayed normal flower morphology comparable to that of its euplasmic B. juncea counterpart except for sterile anthers, Og2 retained homeotic-like floral modification of stamens to petal-like structures and several other floral deformities observed in the chlorotic (Ogu) B. juncea cv. RLM198 (or OgRLM). With respect to the mitochondrial genome, Og1 showed 81% genetic similarity to the fertile cultivar RLM while Og2 showed 93% similarity to OgRLM. In spite of recombination and rearrangements in the mitochondrial genomes in the cybrids, expression patterns of 10 out of 11 mitochondrial genes were similar in all the three CMS lines; the only exception was atp6, whose expression was altered. While Og1 showed normal atp6 transcript similar to that in RLM, in Og2 and OgRLM weak expression of a longer transcript was detected. These results suggest that the homeotic-like changes in floral patterning leading to petaloid stamens in Og2 and OgRLM may be associated with aberrant mitochondrial gene expression.

  14. Alterations of RNA Editing for the Mitochondrial ATP9 Gene in a New orf220-type Cytoplasmic Male-sterile Line of Stem Mustard (Brassica juncea var. tumida)

    Jing-Hua Yang; Ming-Fang Zhang; Jing-Quan Yu

    2007-01-01

    RNA editing for the mitochondrial ATP9 gene of encoding regions has been observed in both cytoplasmic malesterile and maintainer lines of stem mustard, where its editing capacity varied spatially and temporally in the cytoplasmic male sterility (CMS) line. There were four RNA editing sites for the mitochondrial ATP9 gene according to its normal editing sites in mustard, of which three sites occurred as C-to-U changes and one as a U-to-C change.As a result, the hydrophobicity of deduced ATP9 protein was reduced due to the conversions at its 17th, 45th and 64th positions. Meanwhile, the conservation of deduced ATP9 protein was enhanced by changes at the 56th position.Loss of a specific editing site for ATP9 was observed in juvenile roots, senile roots, senile leaves and floret buds of the CMS line. Comparatively, complete RNA editing for ATP9 gene was retained in juvenile roots, juvenile leaves and floret buds of its maintainer line; however, the loss of a specific editing site for ATP9 gene occurred at senile roots and senile leaves in its maintainer line. These observations allow us to produce a hypothesis that the dysfunction of a specific mitochondrisl gene arising from RNA editing could probably be a factor triggering CMS and organ senescence through unknown cross-talk pathways during development.

    Pollens of Sumian 22 were irradiated by 60Co γ-rays at a dose of 20Gy, then fertilized to pistil and harvested seed. Three male-sterile lines were selected from M1 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.

    The cytoplasm male sterile(CMS)line and its maintainer line of the newly-bred non-heading Chinese cabbage were taken as experimental materials.The production rate of superoxide anion radical(O2-),contents of malondialdehyde(MDA)and hydrogen peroxide(H2O2),and the activities of superoxide dismutase(SOD),peroxidase(POD),catalase(CAT)as well as ascorbate peroxidase(APX)were determined in buds of different developmental stages and leaves during vegetative and florescence stages.As showed by the results,there were higher levels of MDA and H2O2 contents,higher 02- production rate and higher activities of SOD,POD,and CAT in the buds of the CMS lines than that in the buds of the fertile lines,while the APX activity was different from the other three enzymes above.There were differences in activities of protective enzymes in leaves but no significant differences in MDA contents and O2- production rate,which showed that the differences in metabolism of active oxygen between CMS and its maintainer were mainly apparent in reproductive organs.

    To establish a simple and rapid method for isolating mitochondrial DNA (mtDNA) from Brassica vegetables, the effects of different factors on mtDNA extraction were investigated firstly. A new protocol includes five steps: organelle isolation, deoxyribonuclease treatment, lysis, RNase treatment, and deproteinization. Results indicate that a 15 min-lysis time can achieve higher mtDNA yields from etiolated seedlings. Moreover, it is found that the inflorescence of the cytoplasmic male sterile (CMS) line is unfit for the isolation of mtDNA. The mtDNA isolated using this method is intact and pure, and can be used for further molecular analysis. Subsequently, the genomic and transcriptional differences of atps and coxs genes on the mitochondria between the petaloid-type CMS line and its maintainer line have been identified. RFLP analysis revealed that out of the five atps and three coxs genes, except of atp4 and cox3, the others mtDNA protein coding genes exhibited polymorphisms, respectively. This results suggest that atps and coxs genes are located in a long mtDNA fragment, and the mtDNA evolves rapidly in structure between the CMS line and its maintainer line in tuber muster. Northern blot analysis showed that the expression level of these genes in flower bud is higher than that of leaf and flower, and that, alternative splicing have been found among the atp6, atp8 and cox3 genes, respectively. Our results modified a efficient protocol for isolating the mtDNA, and provided some novel molecular markers indicating the CMS trait in tuber mustard. The comparative analysis presented in this study allows a more comprehensive understanding of the molecular mechanism on CMS in Brassica crops. PMID:24385295

    2008-01-01

    [Objective] The study aimed to reveal the effect of photoperied and temperature on male fertility of cytoplasmic male sterile line Vtai911289a in wheat and discuss the mechanism of male fertility alteration. [Method] The sowing-date tests and designed conditions were conducted during 2003 - 2005. [Result] Fertility of Vtai911289acould alter under specific photopefiod and temperature conditions. Temperature is one of the main factors influencing male fertility of the male sterile lines. Vtai911289a showed stable sterility under the condition of the mean of daily temperature at fertility sensitive stage lower than 19 ℃ and presented partial fertility when the mean of daily temperature at fertility sensitive stage lower than 20 -22 ℃. Photoperiod to some extent affects the male fertility of Vtai911289a, long-day condition is helpful for the male fertility of the sterile line. [Conclusion] The application of pbotoperiod tempera- ture-sensitive cytoplasmic male sterile line in production has a higher safety than that of temperature sensitive sterile line.

  1. Space Shuttle ascent aborts

    Schmidgall, Richard A.

    1989-09-01

    Specific guidance functions and trajectory design of return to launch site (RTLS) and transoceanic abort landing (TAL) intact abort profiles, as well as the increasing emphasis on contingency aborts, are presented. Various systems failures including Space Shuttle main engine failures and detailed technical analyses, including the design of powered flight abort trajectories, are considered. The most critical of flight abort situations is the RTLS, while TAL is the preferred abort when uphill capability is no longer available. It is concluded that one principle must remain to ensure continuing success of Space Shuttle flights: namely that intact and contingency aborts necessitate development to ensure safe return of the vehicle, payload, and crew whenever possible.

  2. Should abortion be legalized?

    Sodhy, L S

    1968-01-01

    Abortion is an important means of family planning, especially when contraception is unavailable or when it fails. Morbidity associated with legal abortion is low, though illegal abortion is a common cause of maternal mortality. The Union of Soviet Socialist Republic, Hungary, Yugoslavia, Czechoslovakia, Romania, Poland, and the German Demogratic Republic all have laws legalizing abortion. Legalized abortion is the surest method of population control and should be promoted if the moral and religious objections can be overcome. PMID:12255647

  3. Abortion Before & After Roe

    Joyce, Ted; Tan, Ruoding; Zhang, Yuxiu

    2013-01-01

    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.

    2015-01-01

    A novel genetic male sterile germplasm was developed by successively crossing of (C. annuum x C. chinense) x C. pubescens and by chemical mutagenesis in pepper. The sterile anthers showed morphological abnormalities, but pistils developed normally with fine pollination capability. We investigated fertility segregation through sib-crossing of the same strains and test crossing by male sterile plants with 6 advanced inbred lines. The results showed that male fertility in the pepper was dominant in the F1 generation and segregated at a rate of 3:1 in the F2 generation, suggesting that monogenic male sterility was recessive and conformed to Mendelian inheritance. Cyto-anatomy analysis revealed that microspore abortion of sterile anthers occurred during telophase in the microspore mother cell stage when tapetal cells showed excessive vacuolation, resulting in occupation of the loculi. The microspore mother cells self-destructed and autolyzed with the tapetum so that meiosis in pollen mother cells could not proceed past the tetrad stage. PMID:25966098

  5. Abortion and psychiatric practice.

    Stotland, Nada L

    2003-03-01

    The subject of abortion is fraught with politics, emotions, and misinformation. A widespread practice reaching far back in history, abortion is again in the news. Psychiatry sits at the intersection of the religious, ethical, psychological, sociological, medical, and legal facets of the abortion issue. Although the religions that forbid abortion are more prominent in the media, many religions have more liberal approaches. While the basic right to abortion has been upheld by the U.S. Supreme Court, several limitations have been permitted, including parental notification or consent (with the possibility of judicial bypass) for minors, waiting periods, and mandatory provision of certain, sometimes biased, information. Before the Roe v. Wade decision legalizing abortion in 1973, many women were maimed or killed by illegal abortions, and psychiatrists were sometimes asked to certify that abortions were justified on psychiatric grounds. Currently, there are active attempts to convince the public and women considering abortion that abortion frequently has negative psychiatric consequences. This assertion is not borne out by the literature: the vast majority of women tolerate abortion without psychiatric sequelae. The psychiatric outcome of abortion is best when patients are able to make autonomous, supported decisions. Psychiatrists need to know the medical and psychiatric facts about abortion. Psychiatrists can then help patients prevent unwanted pregnancies, make informed decisions consonant with their own values and circumstances when they become pregnant, and find appropriate social and medical resources whatever their decisions may be.

  6. Legalized abortion in Czechoslovakia.

    Zidovsky, J; Zwinger, A

    1972-01-01

    A law legalizing abortion was passed nearly 20 years ago in Czechosl ovakia. The law aimed to give women the freedom to decide for themselves whether they want to be pregnant and to decrease the dangers of illegal abortion. The law resulted in a decreased number of abortions and of complications and deaths associated with abortion. Fertility in the country also declined. In 1968 there were more abortions than live births in the country. Since 1957, the law has been modified. The law still aims to prevent the birth of defective children and to protect the life and health of mothers. Each application for abortion is now examined on its own merits. Favorable economic circumstances, prolife social policies adopted by the government, and the new stricter interpretation of the abortion law have resulted in a r ising birthrate since 1969. Contraception is still stressed as preferab le to abortion. PMID:12256872

  10. Late-term abortion.

    Epner, J E; Jonas, H S; Seckinger, D L

    1998-08-26

    Recent proposed federal legislation banning certain abortion procedures, particularly intact dilatation and extraction, would modify the US Criminal Code such that physicians performing these procedures would be liable for monetary and statutory damages. Clarification of medical procedures is important because some of the procedures used to induce abortion prior to viability are identical or similar to postviability procedures. This article reviews the scientific and medical information on late-term abortion and late-term abortion techniques and includes data on the prevalence of late-term abortion, abortion-related mortality and morbidity rates, and legal issues regarding fetal viability and the balance of maternal and fetal interests. According to enacted American Medical Association (AMA) policy, the use of appropriate medical terminology is critical in defining late-term abortion procedures, particularly intact dilatation and extraction, which is a variant of but distinct from dilatation and evacuation. The AMA recommends that the intact dilatation and extraction procedure not be used unless alternative procedures pose materially greater risk to the woman and that abortions not be performed in the third trimester except in cases of serious fetal anomalies incompatible with life. Major medical societies are urged to collaborate on clinical guidelines on late-term abortion techniques and circumstances that conform to standards of good medical practice. More research on the advantages and disadvantages of specific abortion procedures would help physicians make informed choices about specific abortion procedures. Expanded ongoing data surveillance systems estimating the prevalence of abortion are also needed. PMID:9728645

    2007-01-01

    To study the feasibility of utilizing the heterosis of interspecific (Gossypium barbadense × G. hirsutum) hybrid cotton based on cytoplasmic male-sterility system, a G. barbadense male-sterility line HaiA with G. harknessii cytoplasm and its maintainer HaiB were developed by replacing nuclear genome from G. hirsutum to G. barbadense in a backcross breeding program. Its male cell abortion was observed using a light microscope through a paraffin slice for H.E staining technique.The results showed that the abortion characteristics in HaiA were not significantly changed at the cytological level,although G. hirsutum nuclear genome of sterile line was replaced by G. barbadense nuclear genome, and its abortion mainly took place at the stage of the microspore mother cell meiosis. HaiA sterility was very stable because of its early abortion and no-pollens in anthers. Hybrids between HaiA and G. hirsutum restorers were high in pollen viability, boll setting rate, boll weight and lint percentage which contributed to high yield heterosis. It is suggested that HaiA is of great value in the application of cotton interspecific hybrid seed production.

  12. Abortion in Ireland.

    Francome, C

    1992-08-22

    Substantial legal barriers to abortion persist in both the Irish Republic and Northern Ireland, despite growing popular support for abortion under certain conditions. A 1983 amendment to the republic's constitution guarantees the fetus the same right to life s the mother and bans the provision of information on abortion. Although a recent well publicized case of a pregnant, suicidal 14-year-old who travelled to England for an abortion resulted in an Irish Supreme Court ruling that abortion was acceptable in cases of "real and substantial risk" to a woman's life, uncertainty still surrounds the right to travel to England for the procedure. In Northern Ireland, the 1967 Abortion Act does not apply and abortions are denied even in cases of rape and incest. A total of 1766 women from Northern Ireland and 4158 from the republic travelled to England for abortions in 1991. Public opinion seems to have shifted toward support for less restrictive abortion laws, however. Whereas 80% of those surveyed in a 1980 Irish poll supported to ban on abortion in all cases, this statistic had dropped to 30% by 1990. Similarly, a 1991 poll taken in Northern Ireland found 80% of respondents to be a favor of abortion in cases where the procedure is necessary to maintain a woman's physical or mental health.

    2002-01-01

    Inter-simple sequence repeat (ISSR) analysis was carried out on a F2 population of 147 plants derived from a cross between a wheat male fertility restorer line 2114 and a male sterile line ND44A. Out of 43 primers examined, 18 primers produced distinguishable, polymorphic bands between the two parents. Linkage analysis in the mapping population showed that two markers UBC-808 and UBC-848 were closely linked with the restorer gene R f6 of the Triticum timopheevii CMS system. The distance between the two markers and the restorer gene was 7.9 cM and 4.9 cM, respectively. Also two parents were screened with 181 pairs of SSR primers, of which, 34.3% showed polymorphisms. But no locus was found linked with the restorer gene.Compared with the SSR technique, the ISSR approach used in the experiment provided more information and proved to be a valuable method to identify alien fragments.

  14. The moral significance of spontaneous abortion.

    Murphy, T F

    1985-01-01

    Spontaneous abortion is rarely addressed in moral evaluations of abortion. Indeed, 'abortion' is virtually always taken to mean only induced abortion. After a brief review of medical aspects of spontaneous abortion, I attempt to articulate the moral implications of spontaneous abortion for the two poles of the abortion debate, the strong pro-abortion and the strong anti-abortion positions. I claim that spontaneous abortion has no moral relevance for strict pro-abortion positions but that the ...

  15. Molecular classification of Maize cytoplasms in a breeding program

    2012-06-01

    Full Text Available Cytoplasmic male sterility (CMS is maternally inherited in most of higher plants species. Together with nuclear restorer genes (Rf, CMS cytoplasms contribute significantly to the efficient production of hybrid seed. Three main types of male sterile cytoplasms are known in maize: T, S and C, which can be distinguished by crossing with specific restorer lines. Recently, PCR markers have been developed allowing the identification of different cytoplasms quickly and accurately. Our objective was to classify the cytoplasm type of maize inbred lines used in our breeding program and F1s obtained from crosses between CMS lines and elite maize lines using PCR multiplex. A multiplex PCR protocol was optimized for our conditions. We obtained the molecular classification of the analyzed cytoplasms. The optimized protocol is a valuable tool to trace male sterile cytoplasms and determine hybrid seed purity in our maize breeding program.

  16. [Abortion law in Italy].

    Havránek, F

    1979-04-01

    On May 28, 1978, the Italian senate passed a law legalizing abortions. The law, passed against the will of the Christian Democrat party and the Vatican, is the most liberal in Western Europe. Any woman 18 or older is free to seek an abortion at a private or public institution during the first 90 days of pregnancy. Abortions can be sought on health, economic, social, family, or psychological grounds. A woman requests an abortion at a hospital or clinic, or from a physician. If termination is deemed urgent, the procedure may be performed immediately. If a request is denied, a woman may make another request 7 days later. Second trimester abortions are permitted only if grave danger to the woman or deformation of the fetus is suspected. Women under 18 meed the permission of their parents or legal guardians; a court may also grant permission. Passage of the law has facilitated open debate on the legal and medical aspects of abortion. It has also guaranteed women access to abortions. Physicians, who on grounds of conscience feel they can't perform abortions, may register to be exempt from having to perform them. They may not, however, deny a woman care before and after her abortion, and if they perform the procedure even once, their name is removed from the exempt register. Additionally, all physicians are bound to attempt to preserve the life of all women as well as any fetus which shows life outside the womb. PMID:445601

  17. "Conservative" views of abortion.

    Devine, P E

    1997-01-01

    The introduction to this essay, which presents and defends the "conservative" position on abortion, explains that this position holds that 1) abortion is wrong because it destroys the fetus; 2) the fetus has full personhood from conception (or very near conception); 3) abortion is only justified under special circumstances, such as when the pregnancy poses a threat to the woman's life; and 4) these conclusions should be reflected in law and public policy. Part 2 sets forth the moral foundations for this position. The third part considers the status of the fetus and reviews the various arguments that have been forwarded to resolve the question, such as the species principle, the potentiality principle, the sentience principle, and the conventionalist principle. Part 4 applies the conservative position to problems posed by hard cases, determines that abortion is a form of homicide from two weeks after fertilization (at the latest), reviews circumstances in which various legal definitions of homicide are applicable, argues for the denial of abortion funding by the state, and notes that violent militancy is not the appropriate response to a belief that abortion should be illegal. Section 5 refutes objections to the conservative position based on the fact that some opponents of abortion also oppose contraception, based on feminist ideals, and based on calls for religious freedom in a pluralistic society. In conclusion, the labels applied to the abortion debate are examined, and it is suggested that "communitarian" is the best term for the conservative position. PMID:12348327

  20. Abortion: the new debate.

    Callahan, D

    1986-06-01

    The course of the debate on abortion following the 1973 Supreme Court decision legalizing abortion has been marked by a variety of medical and scientific developments. Many of these new developments have important legal, psychologic, social, moral, and political implications. The cumulative impact of all these developments may pose a significant challenge to the social and legal foundations of Roe v. Wade. PMID:3523563

  1. Access to legal abortion.

    1993-10-01

    Countries are grouped by the nature and extent of access to legal abortion. The categories include abortion on demand, for social reasons, for health reasons, for rape or incest or to save a mother's life, and only to save a mother's life. Abortion on demand is available for about 40% of the world's population and may have restrictions, such as parental consent or approval of state committees or physicians. There are 22 countries in Europe, 12 in the former Soviet Union, four in Asia, four in the Americas, one in the Middle East (Turkey), and one in Africa (Tunisia) which provide access to early abortion on demand. Abortion for social and economic reasons is available to 21% of the world's population in five countries in Asia, three in Europe (Great Britain, Finland, and Hungary), and one in Africa (Zambia). Abortion for health reasons is available to 16% of the world's population located in 21 countries in Africa, eight in the Americas, seven in Asia, five in Europe, and four in the Middle East. Laws governing about 5% of the world's population permit abortion only in the case of rape, incest, or when a mother's life is in danger (Brazil, Mexico, and Sudan). 18% of the world's population is covered by laws which permit an abortion only when a mother's life is in danger; this includes 19 countries in Africa, 11 in the Americas, nine in Asia, seven in the Middle East, and one in Europe (Ireland).

  2. Abortion; 1 : 2 000 000

    The cartogram represents the crude rate of abortions (number of abortions per 1,000 inhabitants) in the individual districts, crude abortion rate in Slovakia: 0.54 %, number of all abortions (average of 1996 - 1998) is presented. The complicated mosaics reveals two main spatial cores of the highest abortion rate. The first is in the south-west of Slovakia, from Malacky to Komarno, and the second, the largest, is from Ziar nad Hronom and Velky Krtis as far as Michalovce. In contrary, the rate of abortions is registered in the northern districts of the eastern Slovakia, almost the whole region Presov and in the northern districts of the region of Zilina. The size of the sign expresses the absolute number of abortions and simultaneously the structure of abortions: spontaneous and induced abortions. The higher share of the spontaneous abortions (more than a quarter) generally occurs in the districts with the lowest abortion rate. (authors)

  3. Legalized Abortion in Japan

    Hart, Thomas M.

    1967-01-01

    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. PMID:6062283

    This study examines the effect restrictive state abortion laws have on the pregnancy resolution decisions of women with unintended pregnancies. The empirical results find that the abortion ratio and the abortion rate of unintended pregnancies are more sensitive to increases in the abortion price than previous estimates that analyzed total pregnancies (unintended and intended). A Medicaid funding restriction has very little effect on a state's abortion rate of unintended pregnancies, but cause...

  6. Abortion: the hidden plague.

    Tuckwell, S

    1974-05-01

    Abortion is called the invisible plague of all countries and cultures in the twentieth century. It is by far the most important method of birth control in the world today. For every 200 babies born there are at least 100 abortions. In the rich world, a woman who wants to end her pregnancy goes to an abortionist, but for millions of poor women, abortion happens spontaneously in their own homes induced by poor nutrition, sheer physical weakness, and too many pregnancies too close together. In countries where abortion is illegal, millions of women die each year as a result of severe illness or the botched handiwork of backyard operators. The most common complications are massive hemorrhaging, perforation of the uterus, laceration, sepsis, and renal failure. The experience of a great many countries shows that simply legalizing abortion can lead to a dramatic drop in death and illness. Relaxation of abortion laws can save lives, money, and misery for mothers and children. Illegal abortion has become a major problem in Africa there are 3 main types of women who enter hospitals with complications after abortions: 1) the teenager who is away from home; 2) the young woman, often educated, working, and with financial responsibilities, who is ambitious for herself, her husband, or her family; and 3) the woman in her thirties, illiterate, a rural worker, married most of her reproductive life, and pregnant most years. The third type of woman may abort because her system is utterly depleted. Such women must be shown that there is a good chance of survival for her children so that she will not have so many.

  7. The politics of abortion and contraception

    Drezgić Rada

    2004-01-01

    Full Text Available In this article the author challenges several dominant positions that are relevant for understanding demographic trends and contraceptive practices as well as their mutual relationship. First, the author rejects the assumed direct connection between high abortion rates and low fertility. Second, the author challenges the thesis according to which abortions come about because of the lack of contraception and proposes that high abortion rates result from failing contraception i.e. from high failing rates of coitus interruptus which is a preferred method of birth control by men and women in Serbia. Finally, the author argues that giving control over reproductive risk to men does not make women passive victims of male domination. Rather women are, it is argued, active agents in reproducing hegemonic gender roles and relations. In addition, the author shows how gender power relations formed at the micro level may be consequential for macro level politics.

  8. Induced abortion in Indonesia.

    Hull, T H; Sarwono, S W; Widyantoro, N

    1993-01-01

    Induced abortion is one of the most difficult sociomedical problems facing the Indonesian government. While well-known in traditional society, the practice was discouraged by all Indonesian religious groups, and forbidden by the Dutch colonial authorities. Although abortion was technically illegal under the criminal code, a judicial interpretation in the early 1970s permitted medical professionals to offer the procedure so long as they were discreet and careful. The numbers of medical abortions carried out in Indonesia rose dramatically, and there was evidence of matching declines in the incidence of morbidity and mortality caused by dangerous illegal procedures. Medical and community groups campaigned for a more liberal abortion law to protect legal practitioners and stamp out illegal traditional practices. Their efforts appeared to bear fruit in the draft Health Law, but when the law was passed by the legislature in late 1992, the issue was again clouded by contradictions and inconsistencies.

    The law legalizing abortion in France was passed in 1975. To group information of a social and medical nature and to publish reports on their activities, a questionnaire was designed to be filled by physicians and nurses working in centers and hospitals performing abortion. There were 19,000 abortions performed in 1976, and 30,000 are expected to be performed in 1979. The questionnaire contains 80 questions gathering information on socieconomic data, on medical history, on the procedure of the intervention, and on the follow-up visit. A study done on 5700 questionnaires filled between 1976 and 1977 show that most abortion seekers belong to the middle class, and that pregnancy was due in 20% of cases to pill failure, and in 34% of cases to failure of behavioral methods, or to lack of contraception. 88% of patients declared themselves satisfied with the procedure.

  11. Abortion in Present day Vietnam

    Nguyen Thanh Binh

    2012-01-01

    Full Text Available In recent years, the abortion rate in Vietnam has been likely rising. In rural area, this rate is a bit higher than in urban one. Young age groups’ abortion rate is relatively high and ofter higher than older age groups. The main reason is due to their limited awareness of contraceptive methods. Low education level also affects the abortion. The abortion of people at low education level is relatively high, but people with elementary school graduation has the lowest rate of abortion. The Northwest had the highest abortion rate, the lowest rate belonged to the South Central Coast. The abortion rate depends on each couple’s number of alive children. The highest abortion rate is of couples with 1 or 2 alive children. The majority of couples only have one time of abortion for 12 months before research timepoint.

    2015-01-01

    Cytoplasmic male sterility (CMS), a maternally inherited phenotype of pollen sterility in higher plants, is associated with special mitochondrial genes. Wheat K- and V- type CMS, respectively produced by the introduction of Aegilops kotschyi and Ae. ventricosa or Ae. variabilis cytoplasts into common wheat, are believed to be the most useful CMS resources of wheat, but their mechanism of male sterility is still unknown. Based on the mitochondrial genome sequences of a wheat K-type CMS line and its maintainer line, 33 mitochondrial genes and 22 open reading frames (orfs , unique genes in wheat K-type CMS line and believed to be candidate CMS genes) between wheat K-, V-type CMS lines and their maintainer line were compared. The results showed that except for atp6, nad6 and rps3 which had obvious differences between the CMS lines and their maintainer line, the rest 30 mitochondrial genes had over 98%identity between K-, V-type CMS lines and their maintainer line, atp6 and nad6 were also highly conserved between K-and V-type CMS lines. While among the 22 orfs, only orf249 showed 91% identity between K- and V- type CMS lines, other orfs had over 98% identity. These results suggest that mitochondrial genes are highly conserved in wheat K-and V-type CMS lines, and they may have similar CMS gene or mechanism of male sterility. These results lay a foundation for the utility of wheat K-and V-type CMS lines in wheat hybrid production.%细胞质雄性不育(cytoplasmic male sterility, MS)是高等植物中普遍存在的一种母性遗传现象,跟线粒体基因密切相关。小麦K型和V型细胞质雄性不育性是由于粘果山羊草和偏凸山羊草或易变山羊草的细胞质导入普通小麦中产生的,被认为是最有利用潜力的小麦不育种质,但是其不育性产生的机理还不清楚。本研究在已知小麦K型细胞质雄性不育系和保持系线粒体基因组序列的基础上,比较分析了K型,V型不育系和保持系中33

    Rice restorer lines were treated with 60Co γ-ray and 4 male sterile mutants obtained with the fertility of controlled by 4 non-allelic recessive genes, respectively. Sixty combinations were made by using male sterile plants/fertile plants as male parents, and 15 different cytoplasmic substitution lines of the same cell nucleus as female parents. The result showed that F1 spikelets were normal and fertile, and different numbers of male sterile plants were segregated in F2. Complete fertility genotype was not found among interactions between induced male sterile genes and alien-cytoplasms. (authors)

  17. Gene, protein and network of male sterility in rice

    Wang eKun

    2013-04-01

    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.

    2008-01-01

    In order to find out a new pathway for utilizing heterosis of Zinnia elegans and accelerate breeding process, the mechanism of anther development of a male sterile line was explored. Backcross, sibmating, selfing of fertile plants and testcross with inbred lines were analyzed and identified in the field, and cytology was observed. Recessive nucleus male sterile line AH209AB capable of being a maintainer was obtained by successive backcrosses with male sterile plants and fertile F, plants as male parents. Cytological and anatomical studies indicated that: (1) The wall of normal anther was constituted of four layers of cells such as epidermis, powder chamber wall, middle level and tapetum cells. The process in meiosis of pollen mother cell in Zinnia elegans was normal and cytoplasm divided simultanously. Mature pollen grain was tricellular type. (2) The petal of male sterile plant degraded as a thread-like structure, the stamens were villiform in appearance and no pollens were formed. The result showed that the anther of male sterile plant no longer proceed to differentiate spore mother cell and the pollen sac after the formation of the tissue of sporogenous cells, there was no evident boundary between tapetum cell, middle lamella and inner wall of PMC, tapetal cells did not develop from the very beginning. So the abortion type was completely structural male sterility. The male sterile line belongs to non-sporange male sterile type and is of great use in F1 seeds production.

  19. Can paternal leakage maintain sexually antagonistic polymorphism in the cytoplasm?

    Kuijper, B; Lane, N; Pomiankowski, A

    2015-02-01

    A growing number of studies in multicellular organisms highlight low or moderate frequencies of paternal transmission of cytoplasmic organelles, including both mitochondria and chloroplasts. It is well established that strict maternal inheritance is selectively blind to cytoplasmic elements that are deleterious to males - 'mother's curse'. But it is not known how sensitive this conclusion is to slight levels of paternal cytoplasmic leakage. We assess the scope for polymorphism when individuals bear multiple cytoplasmic alleles in the presence of paternal leakage, bottlenecks and recurrent mutation. When fitness interactions among cytoplasmic elements within an individual are additive, we find that sexually antagonistic polymorphism is restricted to cases of strong selection on males. However, when fitness interactions among cytoplasmic elements are nonlinear, much more extensive polymorphism can be supported in the cytoplasm. In particular, mitochondrial mutants that have strong beneficial fitness effects in males and weak deleterious fitness effects in females when rare (i.e. 'reverse dominance') are strongly favoured under paternal leakage. We discuss how such epistasis could arise through preferential segregation of mitochondria in sex-specific somatic tissues. Our analysis shows how paternal leakage can dampen the evolution of deleterious male effects associated with predominant maternal inheritance of cytoplasm, potentially explaining why 'mother's curse' is less pervasive than predicted by earlier work.

    BackgroundThe circumstances under which women obtain unsafe abortion vary and depend on the traditional methods known and the type of providers present. In rural Tanzania women often resort to traditional providers who use plant species as abortion remedies. Little is known about how these plants...... are used and their potential effect.MethodsData were obtained among women admitted with incomplete abortion at Kagera Regional Hospital during the period January - June, 2006. The women underwent an empathetic interview to determine if they had experienced an unsafe abortion prior to their admission....... In all 125/187 women revealed having had an unsafe abortion. The women identified as having had an unsafe abortion underwent a questionnaire interview where information about abortion provider and abortion method used was obtained through open-ended questions.

  2. [Spontaneous abortion. Etiologic survey. Results].

    Baaklini, N; Anguenot, J L; Boulanger, J C; Vitse, M

    1990-12-01

    The definition of repeated spontaneous abortions is subject to caution. For some, it corresponds to at least three repeated spontaneous abortions with no normal previous pregnancy; for others, it comprises the repeated spontaneous abortions occurring after a normal pregnancy. It is a frequent problem, especially if one tries to give a wider definition. The authors studied the frequency of repeated spontaneous abortions in a continuous series of 14,857 pregnancies which took place between January 1982 and December 1988. In the study of the aetiology of the repeated spontaneous abortions in the various groups of women defined according to the number of previous pregnancies and abortions, they find the classical causes of repeated spontaneous abortions in all the categories: therefore, it seems legitimate to them that a wider definition be given for repeated spontaneous abortions.

  3. Did Legalized Abortion Lower Crime?

    2001-01-01

    This paper examines the relationship between the legalization of abortion and subsequent decreases in crime. In a current study, researchers estimate that the legalization of abortion explains over half of the recent decline in national crime rates. The association is identified by correlating changes in crime with changes in the abortion ratio weighted by the proportion of the criminal population exposed to legalized abortion. In this paper, I use an alternative identification strategy. I an...

    Conclusions: Previous history of spontaneous abortion is associated with adverse pregnancy outcome. There is increased risk of abortion, preterm delivery, need for caesarean sections and fetal loss in cases of previous spontaneous abortions. These complications and fetal loss can be reduced by booking the patients and giving due antenatal care. [Int J Reprod Contracept Obstet Gynecol 2015; 4(6.000: 1891-1893

    Abstract Objective To determine the location of Canadian abortion services relative to where reproductive-age women reside, and the characteristics of abortion facilities and providers. Design An international survey was adapted for Canadian relevance. Public sources and professional networks were used to identify facilities. The bilingual survey was distributed by mail and e-mail from July to November 2013. Setting Canada. Participants A total of 94 abortion facilities were identified. Main outcome measures The number and location of services were compared with the distribution of reproductive-age women by location of residence. Results We identified 94 Canadian facilities providing abortion in 2012, with 48.9% in Quebec. The response rate was 83.0% (78 of 94). Facilities in every jurisdiction with services responded. In Quebec and British Columbia abortion services are nearly equally present in large urban centres and rural locations throughout the provinces; in other Canadian provinces services are chiefly located in large urban areas. No abortion services were identified in Prince Edward Island. Respondents reported provision of 75 650 abortions in 2012 (including 4.0% by medical abortion). Canadian facilities reported minimal or no harassment, in stark contrast to American facilities that responded to the same survey. Conclusion Access to abortion services varies by region across Canada. Services are not equitably distributed in relation to the regions where reproductive-age women reside. British Columbia and Quebec have demonstrated effective strategies to address disparities. Health policy and service improvements have the potential to address current abortion access inequity in Canada. These measures include improved access to mifepristone for medical abortion; provincial policies to support abortion services; routine abortion training within family medicine residency programs; and increasing the scope of practice for nurses and midwives to include abortion

  15. The consequences of abortion legislation.

    Braude, M

    1983-01-01

    This article examines the consequences of the 1973 US Supreme Court decision legalizing abortion as well as potential implications of proposed legilation aimed at nullifying this decision. In addition to giving women the right to determine their own reproduction, legal abortion had had beneficial health effects for both mothers and infants. The partial reversal of abortion gains due to restrictions on public funding and limitations on how and where abortions can be performed has produced a slight increase in abortion mortality, but the impact has not been dramatic. Moreover, each year since 1973, women have been obtaining abortions earlier in pregnancy. Abortion may be experienced as a loss by the mother, but there is no evidence of serious psychological sequelae. In contrast, a large body of evidence supports the physical, psychological, and social benefits of legal abortion to women, children, and families. However, proponents of the proposed Human Life Amendment place protection of the rights of the fetus over all other considerations. Their antiabortion actions have challenged the medical tradition of privacy and the confidentiality of the doctor-patient relationship. Most supporters of legal abortion would prefer that there be fewer abortions; such a decrease is more likely as a result of better education and contraceptive methods rather than coercion.

  16. Abortion: taking the debate seriously.

    Kottow Lang, Miguel Hugo

    2015-01-01

    Voluntarily induced abortion has been under permanent dispute and legal regulations, because societies invariably condemn extramarital pregnancies. In recent decades, a measure of societal tolerance has led to decriminalize and legalize abortion in accordance with one of two models: a more restricted and conservative model known as therapeutic abortion, and the model that accepts voluntary abortion within the first trimester of pregnancy. Liberalization of abortion aims at ending clandestine abortions and decriminalizes the practice in order to increase reproductive education and accessibility of contraceptive methods, dissuade women from interrupting their pregnancy and, ultimately, make abortion a medically safe procedure within the boundaries of the law, inspired by efforts to reduce the incidence of this practice. The current legal initiative to decriminalize abortion in Chile proposes a notably rigid set of indications which would not resolve the three main objectives that need to be considered: 1) Establish the legal framework of abortion; 2) Contribute to reduce social unrest; 3) Solve the public health issue of clandestine, illegal abortions. Debate must urgently be opened to include alternatives in line with the general tendency to respect women's decision within the first trimester of pregnancy. PMID:26057783

    Lima, Joana Madureira; Reeves, Aaron; Billari, Francesco; McKee, Martin; Stuckler, David

    2016-06-01

    Economic hardship accompanying large recessions can lead families to terminate unplanned pregnancies. To assess whether abortions have risen during the recession, we collected crude abortion data from 2000 to 2012 from Eurostat for countries that had legal abortions and complete data. Declining trends in abortion ratios between 2000 and 2009 have been reversing. Excess abortions between 2010 and 2012 totaled 10.6 abortions per 1000 pregnancies ending in abortion or birth or 6701 additional abortions (95% CI 1190-9240) with stronger effects in younger ages. Economic shocks may increase recourse to abortion. Further research should explore causal pathways and protective factors. PMID:27009038

  18. Immunologically mediated abortion (IMA).

    Giacomucci, E; Bulletti, C; Polli, V; Prefetto, R A; Flamigni, C

    1994-06-01

    Roughly 20% of all clinical pregnancies evolve into "spontaneous abortions". The causes of spontaneous abortion have been determined in under 60% of the total and comprise genetic, infectious, hormonal and immunological factors. In some cases the immune tolerance mechanism may be impaired and the foetus immunologically rejected (IMA, immunologically mediated abortion). The immunological mechanism implicated depends on the time in which pregnancy loss takes place. During preimplantation and up to the end of implantation (13th day) the cell-mediated immune mechanism (potential alloimmune etiologies) is responsible for early abortion. This mechanism involves immunocompetent decidual cells (eGL, endometrial granulated lymphocytes) already present during pre-decidualization (late luteal phase) and their production of soluble factors or cytokines. Once the implantation process is over, after blastocyst penetration of the stroma and the decidual reaction of uterine tissue, IMA could be caused by cell-mediated and humoral mechanism (anti-paternal cytotoxic antibodies or autoantibody etiology), by the production of paternal anti major histocompatibility complex antibodies, or even by an autoimmune disorder leading to the production of autoantibodies (antiphospholipid antibodies, antinuclear antibodies or polyclonal B cell activation). The diagnostic work-up adopted to select IMA patients is crucial and includes primary (karyotype of both partners, toxo-test, hysterosalpingography, endometrial biopsy, thyroid function tests, serum hprolactin, luteal phase dating) and secondary (full hemochromocytometric test, search for LE cells, lupus anticoagulant, anticardiolipin, antinuclear antibodies, Rheumatoid factor, blood complement VDRL) investigations. Therapeutical approaches vary. If autoimmune disorders are demonstrated therapies with different combinations of corticosteroids, aspirin and heparin or intravenous immunoglobulin are administered. Otherwise, therapy with paternal

  1. Abortion law reform in Nepal.

    Upreti, Melissa

    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. PMID:24890742

  2. Legal abortion and public health.

    Tietze, C

    1984-01-01

    Over 15 million abortions have been performed in the US since the process of abortion legalization began in 1967. Consequences of legalization have included a marked reduction of pregnancy-related mortality and the prevention in many cases of the birth of infants with major physical or mental defects. Prenatal diagnosis, backed up by selective abortion, has made procreation a possibility for many couples who might otherwise avoid childbearing. However, the number of abortions performed on the basis of prenatal diagnosis remains small, comprising only about .01% of all legal abortions. In recent months, the pro-choice movement in the US has been handed 2 important victories: the US Supreme Court reaffirmed the 1973 decision legalizing abortion and the US Senate defeated a constitutional amendment intended to reverse this decision. As a result of these victories, contributions to pro-choice groups have declined. Continued vigilance is needed to protect these victories. PMID:12267089

  3. The abortion debate in Australia.

    Read, Christine Margaret

    2006-09-01

    I recently watched a fascinating documentary about the crusade of Dr Bertram Wainer in the 1960s to bring the practice of illegal abortion in Victoria to an end. It documented the profound horror of the backyard abortion that so often ended in infection, sterility or death, and served as a potent reminder of a practice to which we must never return. Of course that cant happen again, abortion is legal now, isnt it? In Victoria in 1969 a Supreme Court judge ruled that an abortion is not unlawful if a doctor believed that: the abortion is necessary to preserve the woman from serious danger to her life or physical or mental health (Menhennit ruling). In Australia today however, abortion law remains conditional, unclear and inconsistent and, except in the ACT, is still part of criminal statutes. PMID:16969440

  4. Dworkin and Casey on abortion.

    Stroud, Sarah

    1996-01-01

    This article responds to two important recent treatments of abortion rights. I will mainly discuss Ronald Dworkin's recent writings concerning abortion: his article "Unenumerated rights: whether and how Roe should be overruled," and his book Life's Dominion. In these writings Dworkin presents a novel view of what the constitutional and moral argument surronding abortion is really about. Both debates actually turn, he argues, on the question of how to interpret the widely shared idea that human life is sacred. At the heart of the abortion debate is the essentially religious notion that human life has value which transcends its value to any particular person; abortion is therefore at bottom a religious issue. Dworkin hopes to use this analysis to show that the religion clauses of the First Amendment provide a "textual home" for a woman's right to choose abortion. I wish to scrutinize this suggestion here; I want to probe the precise consequences for abortion rights of such an understanding of their basis. I will argue that the consequences are more radical than Dworkin seems to realize. The other work I will examine here is the important 1992 Supreme Court decision on abortion, Planned Parenthood v. Casey. The controlling opinion in that case, written jointly by Justices Kennedy, O'Connor, and Souter, strongly reaffirmed Roe v. Wade, but also upheld most of the provisions of a Pennsylvania statute that had mandated various restrictions on abortion. The justices' basis for upholding these restictions was their introduction of a new constitutional standard for abortion regulations, an apparently weaker standard than those that had governed previous Supreme Court abortion decisions. I think there is a flaw in Casey's new constitutional test for abortion regulations, and I will explain, when we turn to Casey, what it is and why it bears a close relation to Dworkin's reluctance to carry his argument as far as it seems to go.

  6. On abortion: exploring psychological meaning and attitudes in a sample of Mexican gynecologists.

    Marván, Ma Luisa; Álvarez del Río, Asunción; Campos, Zaira

    2014-04-01

    Elective abortion has become an issue of ethical and political debate in many countries including Mexico. As gynecologists are directly involved in the practice of abortion, it is important to know the psychological meaning that the term 'elective abortion' has for them. This study explores the psychological meaning and attitudes toward elective abortion of one hundred and twenty-three Mexican gynecologists. We used the semantic networks technique, which analyzed the words the participants associated with the term 'elective abortion'. The defining words most frequently used by participants implied a negative sanction. There were important differences by gender and religiosity: male gynecologists, as well as those with strong religious beliefs (mainly Catholics), revealed a more negative psychological meaning and more negative attitudes than females or physicians with weak religious beliefs. A contribution of the present study is that it highlights the importance of psychology to enhancing understanding of the issue of elective abortion. PMID:23170806

However, the Shiite authorities have not accepted to legitimate abortion in unwanted pregnancies and even in pregnancies resulted from adultery (Zina or rape."nThe debate over abortion is still controversial as ever. There are some important and notable related Fatwas that make jurisprudical basis for some new and problem solving legal acts, showing the inherent and valuable flexibility of the Shiite jurisprudence in dealing with such important issues. Some related issues, such as the priority of saving the life of mother after ensoulment can be referred to jurisprudical authorities for more assessment.

  11. Living through some giant change: the establishment of abortion services.

    Schoen, Johanna

    2013-03-01

    This article traces the establishment of abortion clinics following Roe v Wade. Abortion clinics followed one of two models: (1) a medical model in which physicians emphasized the delivery of high quality medical services, contrasting their clinics with the back-alley abortion services that had sent many women to hospital emergency rooms prior to legalization, or (2) a feminist model in which clinics emphasized education and the dissemination of information to empower women patients and change the structure of women's health care. Male physicians and feminists came together in the newly established abortion services and argued over the priorities and characteristics of health care delivery. A broad range of clinics emerged, from feminist clinics to medical offices run by traditional male physicians to for-profit clinics. The establishment of the National Abortion Federation in the mid-1970s created a national forum of health professionals and contributed to the broadening of the discussion and the adoption of compromises as both feminists and physicians influenced each other's practices.

    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 argumen...

Exemplified are display vectors wherein the structural protein is the T7 bacteriophage capsid protein. More specifically, in the exemplified display vectors the C-terminal amino acid residue of the portion of the capsid protein is joined to the N-terminal residue of the protein or peptide of interest. The portion of the T7 capsid protein exemplified comprises an N-terminal portion corresponding to form 10B of the T7 capsid protein. The display vectors are useful for high copy number display or lower copy number display (with larger fusion). Compositions of the type described herein are useful in connection with methods for producing a virus displaying a protein or peptide of interest. 1 fig.

  14. Sociocultural determinants of induced abortion

    Objective: To determine the frequency of induced abortion and identity the role of sociocultural factors contributing to termination of pregnancy and associated morbidity and mortality in hospital setting. Subjects and Methods: 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. Results: 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 concentration. 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 (43.8%) abortion was carried out by Daiyan (traditional midwives). Serious complications like uterine perforation with or without bowel injury were encouraged in 25 (43.8%) of these women. During the study period illegally induced abortion accounted for 6 (10.5%) maternal deaths. Conclusion: Prevalence of poverty, illiteracy, grand multiparity and non-practice of contraception are strong determinants of induced abortion. (author)

  16. Birth, meaningful viability and abortion.

    Jensen, David

    2015-06-01

    What role does birth play in the debate about elective abortion? Does the wrongness of infanticide imply the wrongness of late-term abortion? In this paper, I argue that the same or similar factors that make birth morally significant with regard to abortion make meaningful viability morally significant due to the relatively arbitrary time of birth. I do this by considering the positions of Mary Anne Warren and José Luis Bermúdez who argue that birth is significant enough that the wrongness of infanticide does not imply the wrongness of late-term abortion. On the basis of the relatively arbitrary timing of birth, I argue that meaningful viability is the point at which elective abortion is prima facie morally wrong. PMID:25012846

  17. 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

  18. Cytoplasmic inheritance in Nicotiana tabacum L. autoradiography

    Tobacco pollen grains were labelled with leucine 14C, part then being used for artificial pollination of specific Nicotiana lines, while the rest were processed directly, as controls, for light and electron microscopy and autoradiography. The apparent differences in silver grain density observed in the controls may be related to the different physiological states of pollen grains during labelling. A radioactive precursor does not impair the viability and fertility of pollen grains. Samples taken and observed at successive intervals after pollination allowed the monitoring of cytoplasmic transmission to the embryo sac. The cytoplasmic materials remain confined within the micropylar canal and the embryo sac for several days after pollination. The tagged mitochondria found in the embryo sac are not necessarily of male origin, since the radioactive materials they contain might be products of metabolism. (author)

  19. Senate, 59-40, defeats move to strike limits on Medicaid abortion coverage.

    1993-10-01

    On September 24 1993, the US Senate voted to limit access to abortion services for poor women under Medicaid to cases of rape, incest, or where pregnancy poses a risk to a woman's health. The US House of Representatives had earlier adopted a similar amendment, so now the bill will be sent to the President. The original amendment limited abortion access under Medicaid to only poor women whose life was endangered. Its sponsor proposed to expand coverage to cases of rape and incest based on pragmatic political grounds and knowing that this expansion would include fewer than 100 abortions. Abortion rights groups considered this 1993 expansion of the amendment as a step toward restoring real equity in access to abortion. Nevertheless, like the antiabortion groups, they do not consider it progress. The 5 female Senators vowed to fight to obtain full abortion coverage under Medicaid. The also pointed out to their male colleagues that this amendment discriminates against poor women. Many senators voted for the amendment because they chose the lesser of 2 evils. Many people are concerned that this bill indicates how Congress will treat poor women when health care reform legislation arrives and its concern for all women's right to access to abortion services under government-sponsored programs. More than 40 Senators can clearly see the difference between direct federal funding of abortion and other forms of government involvement. Further, Congress did approve the bill granting federal employees access to abortion services, but it passed by only 1 vote. Abortion rights proponents and abortion opponents should consider these aforementioned facts when preparing for the debate over abortion coverage under health care reform. PMID:12286980

  1. New German abortion law agreed.

    Karcher, H L

    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. PMID:7613423

    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 ...

  6. Participation of nurses in abortions.

    Neustatter, P L

    1980-11-29

    Doctors for a Woman's Choice on Abortion would agree with 1 point in Lord Denning's ruling on the role of nurses in abortions induced by (PGS) prostaglandins (November 15, p. 1091). The nurse should not be doing a doctor's job, as Lord Denning indicated, and we sympathize with any nurse who is doing so (though the 1967 Abortion Act allows any nurse to abstain, on grounds of conscience). However, the ruling that nurses are not legally covered to participate in any way with the "procuring of a miscarriage" (using terminology of the 1861 Offenses against the Persons Act upon which the ruling is based) does not require a radical change in the practice of late abortions (constituting only 7% of the terminations) or any change in the law. PG abortion can be done without a nurse. With the extraamniotic technique, a very cheap pump can be used to give subsequent doses of the PG (a function normally performed by a nurse) through the catheter left inserted through the cervix after the 1st dose has been given by the doctor. Alternatively, the intraamniotic method can be used, where PG is instilled into the amniotic sac via a needle passed through the abdominal wall. This normally requires only 1 dose, given by the doctor. Rarely are subsequent doses needed; however they could be given by the doctor with very little addition to his or her workload. While the fact that PG abortion can be done without nurses is not realized, late abortion will be restricted, a situation which is entirely deplorable. Also deplorable are the comments of an antiabortion nature made by Lord Denning, over and above the legal ruling in his jurisdiction to make. His ruling, furthermore, seems to have been sufficiently confused for the Department of Health to withdraw its circular on abortion and await an interpretation before issuing another. PMID:6107800

    Ten years have passed since John Donohue and Steven Levitt initially proposed that legalized abortion played a major role in the dramatic decline in crime during the 1990s. Criminologists largely dismiss the association because simple plots of age-specific crime rates are inconsistent with a large cohort affect following the legalization of abortion. Economists, on the other hand, have corrected mistakes in the original analyses, added new data, offered alternative tests and tried to replicat...

  9. Abortion - a philosophical perspective

    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.

  10. Cellular Subcompartments through Cytoplasmic Streaming.

    Pieuchot, Laurent; Lai, Julian; Loh, Rachel Ann; Leong, Fong Yew; Chiam, Keng-Hwee; Stajich, Jason; Jedd, Gregory

    2015-08-24

    Cytoplasmic streaming occurs in diverse cell types, where it generally serves a transport function. Here, we examine streaming in multicellular fungal hyphae and identify an additional function wherein regimented streaming forms distinct cytoplasmic subcompartments. In the hypha, cytoplasm flows directionally from cell to cell through septal pores. Using live-cell imaging and computer simulations, we identify a flow pattern that produces vortices (eddies) on the upstream side of the septum. Nuclei can be immobilized in these microfluidic eddies, where they form multinucleate aggregates and accumulate foci of the HDA-2 histone deacetylase-associated factor, SPA-19. Pores experiencing flow degenerate in the absence of SPA-19, suggesting that eddy-trapped nuclei function to reinforce the septum. Together, our data show that eddies comprise a subcellular niche favoring nuclear differentiation and that subcompartments can be self-organized as a consequence of regimented cytoplasmic streaming.

  13. [Readers' position against induced abortion].

    1981-08-25

    Replies to the request by the Journal of Nursing on readers' positions against induced abortion indicate there is a definite personal position against induced abortion and the assistance in this procedure. Some writers expressed an emotional "no" against induced abortion. Many quoted arguments from the literature, such as a medical dictionary definition as "a premeditated criminally induced abortion." The largest group of writers quoted from the Bible, the tenor always being: "God made man, he made us with his hands; we have no right to make the decision." People with other philosophies also objected. Theosophical viewpoint considers reincarnation and the law of cause and effect (karma). This philosophy holds that induced abortion impedes the appearance of a reincarnated being. The fundamental question in the abortion problem is, "can the fetus be considered a human life?" The German anatomist Professor E. Bleckschmidt points out that from conception there is human life, hence the fertilized cell can only develop into a human being and is not merely a piece of tissue. Professional nursing interpretation is that nursing action directed towards killing of a human being (unborn child) is against the nature and the essence of the nursing profession. A different opinion states that a nurse cares for patients who have decided for the operation. The nurse doesn't judge but respects the individual's decision. Some proabortion viewpoints considered the endangering of the mother's life by the unborn child, and the case of rape. With the arguments against abortion the question arises how to help the woman with unwanted pregnancy. Psychological counseling is emphasized as well as responsible and careful assistance. Referral to the Society for Protection of the Unborn Child (VBOK) is considered as well as other agencies. Further reader comments on this subject are solicited. PMID:6913282

  14. House subcmte. tightens abortion language.

    1978-05-10

    Medicaid would help pay for abortion in fewer circumstances under the fiscal 1979 Department of Health, Education, and Welfare (HEW), appropriations bill approved May 4, 1978, by the House HEW Appropriations Subcommittee than it did in 1978. The new language would permit the funding only if the mother's life would be endangered if the pregnancy were carried to term. Current law permits abortion payments for this reason; if pregnancy results from rape or incest, or if the birth would cause the mother severe and long-lasting physical damage. Behind the scenes pressure probably will be applied to resolve the issue quickly this year since all House members are up for reelection and do not want to have such a sensitive issue intruding on their campaigns. 1 strategy being discussed is the inclusion of riders that would directly or indirectly provide federal funds for abortions in other appropriation measures such as funding for the Defense Department and federal employees health benefits. The House will have to contend with Senator Brooke (R-Massachusetts) ranking minority member on the Senate HEW Appropriations Subcommittee, who is determined to stand firm in favor of liberal abortion funding. With only minimal opposition for his Senate seat this year, Senate staffers say Brooke is not concerned with the possibility of abortion becoming a major campaign issue. It was Brooke who forced the House's hand last year and obtained a more relaxed abortion curb, much to the chagrin of the Carter Administration. The White House, with the President's popularity at a low ebb, would prefer not to be put in a position of taking sides publicly although it prefers the strict curbs. Carter is currently deciding which House members to assist during the campaign and such a no-win issue would only serve to complicate matters. He will have enough of a problem reconciling health spending increases without the added burden of abortion. PMID:12335662

  15. Study of karyotypes in Case of Recurrent Abortions in Gujarat

    N. Parikh

    2015-06-01

    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.

  16. Abortion and the law: the Supreme Court, privacy, and abortion.

    Marsh, F H

    1997-01-01

    This article examines the impact of the continuing politicization of the abortion issue in the US on the rights of women and on the emerging concept of fetal rights. The introduction 1) attributes the "final and total politicization" of a woman's right to control her reproduction to the "undue burden" standard introduced by the Supreme Court in its 1992 Casey decision and 2) claims that, if unchecked, the concept of fetal rights may give the state's interest in protecting potential life supremacy over women's rights. The next section presents an in-depth discussion of the politicization of the right to abortion that covers such topics as how the courts before Casey became the forum for debating abortion policy, how the "undue burden" standard fails to set definite parameters of acceptable state behavior, how the Casey decision in effect abandons the trimester-based framework of reference provided in Roe vs. Wade, how Casey allows states to subtly coerce women seeking abortions, how the Casey decision failed to reduce the intense politicization of abortion, and how the court failed to protect individual rights to health care and abortion funding from states. Part 3 of the article begins its exploration of the concept of "fetal rights" with a sketch of the history of this concept in the US courts starting in 1884 when damages for miscarriage were denied. Ways in which fetal rights compete with the rights of a pregnant woman are described, the Supreme Court is blamed for allowing states to develop this concept, and issues of patient confidentiality versus reporting requirements are considered. It is concluded that the Supreme Court will have to act to limit fetal rights. PMID:12348324

    2004-10-01

    The authors studied the association between female and male alcohol intakes at the time of conception and the risk of spontaneous abortion, including early pregnancy loss detected by urinary human chorionic gonadotropin. After a nationwide mailing to about 50,000 members of four trade unions in Denmark in 1992-1994, 430 couples without previous pregnancy attempts were enrolled when birth control was discontinued, and they were followed until a clinically recognized pregnancy or for six menstrual cycles. Alcohol intake and potential confounding factors were reported in monthly questionnaires. Women collected morning urine for 10 days from the first day of vaginal bleeding in each cycle. The authors detected 186 pregnancies: 131 resulted in childbirth, and 55 resulted in spontaneous abortion (34 detected by urinary human chorionic gonadotropin). Depending on the intake in the cycle of conception and the adjustment factors, female alcohol intake was associated with 2-3 times the adjusted risk of spontaneous abortion compared with no intake, and male alcohol intake was associated with 2-5 times the adjusted risk. Only the adjusted relative risks for 10 or more drinks/week compared with no intake were statistically significant. Both male and female alcohol intakes during the week of conception increased the risk of early pregnancy loss. PMID:15383410

  20. Abortion counseling and the school counselor.

    Duncan, J A; Moffett, C F

    1974-01-01

    The Supreme Court decision of January 22, 1973, legalizing abortion now requires school counselors to examine both their personal and professional positions on abortion information and abortion counseling. To date a review of school counseling literature reveals a failure to deal with abortion as a counseling issue. Also, schools have failed to develop official policies regarding abortion counseling and the distribution of abortion information. The counselors who have provided abortion information to date have done so at the request of a student or parent rather than by making the information generally available. A study in 1973 in Virginia, however, revealed that Virginia counselor educators believed that there was a need for counselors in training to be exposed to abortion information as part of their formal training experience. Generally, today's present exposure to abortion information makes it impossible for counselors to continue to ignore a growing demand for both abortion information and counseling. School counselors must deal with the following questions: 1) What course of action should school counselors take when a pregnant young seeks counseling on alternatives to pregnancy continuation? 2) What is the counselor's professional role in abortion counseling with respect to his or her personal feelings and beliefs? 3) What kind of training if any should school counselors receive regarding abortion counseling? 4) Is there a need for in-service training on abortion counseling for school counselors? 5) Should various professional organizations develop materials that would assist their members in providing abortion counseling? 6) Should institutions such as schools, churches, and community agencies establish policies concerning abortion counseling? Although the answers are not simple, the school counselors and their professional organizations must begin to develop the answers in order to provide good counseling services to young women exercising their right to

    1988-06-01

    "In this paper we first discuss the two-stage process of legalizing induced abortion in Singapore, the initial legalization to make it available on a restrictive basis in 1970 and the complete liberalization to make it available on demand from 1975 onwards. The incidence of abortions registered in the last seventeen years and the major characteristics of aborters are analysed. The impact of abortion on the rapid decline of fertility to below-replacement level is highlighted, and the need to reduce abortion by amending the more liberal aspects of the law are considered at the end of the paper."

  9. Sundhedspersonales holdninger til sene provokerede aborter varierer

    Christensen, Anne Vinggaard; Petersson, Birgit

    2012-01-01

    Internationale undersøgelser viser, at sene provokerede aborter skaber en større bekymring hos sundhedspersonale end tidlige aborter. Den største bekymring er risikoen for, at det aborterede foster udviser livstegn efter fødslen. Undersøgelser peger desuden på, at indikationen for abort, religiøs...... tilknytning og fagligt tilhørsforhold påvirker holdningerne. Antallet af sene provokerede aborter stiger i takt med, at fosterdiagnostikken udvikles, og der er derfor behov for forskning, der kan kaste lys over, hvordan det danske sundhedspersonale forholder sig til sene provokerede aborter....

  10. Unsafe abortion in Tanzania and the need for involving men in postabortion contraceptive counseling

    Rasch, Vibeke; Lyaruu, Mathias A

    2005-01-01

    Targeting male partners involved in unsafe abortions for contraceptive counseling could be an important strategy for decreasing the incidence of unwanted pregnancies, yet few postabortion-care programs have attempted to involve these men. To assess the need for and determine the content of...... postabortion contraceptive counseling for men, this study examined the contraceptive knowledge, attitudes, and practices of male partners of women who have had an unsafe abortion. A survey was administered to 213 men accompanying female partners receiving hospital care after having undergone an unsafe abortion...... their wives and 83 percent accompanying their girlfriends. In general, the men wished to support their partners in practicing contraception, and the majority were willing to participate in contraceptive counseling. These findings suggest that male partners should be included in postabortion...

  11. SELF - INDUCED MEDICAL ABORTION: A RISING CHALLENGE

    Bindoo

    2015-10-01

    Full Text Available In India medical abortion has become acceptable to the masses. As per the MTP Act 2003 medical abortion can be provided by certified providers at approved places or centres which have referral linkages even though the Centre is not approved for MTP. Despit e this in India a large number of abortions are still illegal. People are resorting to abortion without any pre - abortion checkup or counseling which is contrary to the MTP Act. This study was carried out to determine the reasons for resorting to self - induc ed abortion, assess the associated complications and acceptance of contraception after abortion. 77.7% of women in this study included those who reported to hospital following self - administered abortion so did not have any checkup, investigation or counsel ing. 23% women got the prescriptions from RMP, 42.85% from chemists and 30% from friend even though 55% of them were not residing far from the hospital. Following self - administered abortion, women reported with pain abdomen, retained products, pelvic infla mmatory disease and heavy bleeding requiring emergency suction evacuation. These women were not aware about the need for contraception and mistook self - induced abortion as a method for family planning. They resorted to self - induced abortions because they b elieved it to be safe, and presumed that a visit to the hospital is avoidable. 45 % of these women had undergone abortions in the past without any side effect. It is feared that if self - induced medical abortions continues unheeded the health system will get overburdened with resultant complications besides losing an opportunity for contraceptive counseling . It is recommended that the private practitioners may be brought into the system besides ensuring that regulations regarding prescription of drugs and the MTP Act are followed. Besides this masses should be made aware of the legality of medical abortion by using handouts and posters.

  12. Fertility Inheritance of Cytoplasmic Male Sterile Line of Chinese Sorghum “Jinong 105”%中国高粱胞质雄性不育系“吉农105”育性遗传特性的研究

    以中国高粱胞质雄性不育系“吉农105”为研究试材,用9个常用高粱恢复系与之杂交,并对其杂种后代F1、F2及BC1的育性分离比例进行了统计调查。结果表明:供试杂种在F1代全部表现育性恢复,在F2代发生了育性分离,其比例为可育:不育=3:1,同时在BC1代也发生了育性分离,其比例为可育:不育=1:1。根据孟德尔的遗传分离规律,可以推断控制“吉农105”的细胞核内的雄性不育基因为1对隐性基因。%The separation of fertility in F1, F2 and BC1 from crosses between cytoplasmic male sterile line of Chinese sorghum “Jinong 105” and 9 restoring lines of sorghum were statistically analysed. The results showed that the fertility of all hybrids in F1 were restored. However, F2 and BC1 segregated in fertility with respectively 3:1 and 1: 1 fertile to sterile ratio. This indicated that the male sterility of Chinese sorghum “Jinong 105” was controlled by a pair of recessive gene.

  15. Expectant Fathers, Abortion, and Embryos.

    Purvis, Dara E

    2015-01-01

    One thread of abortion criticism, arguing that gender equality requires that men be allowed to terminate legal parental status and obligations, has reinforced the stereotype of men as uninterested in fatherhood. As courts facing disputes over stored pre-embryos weigh the equities of allowing implantation of the pre-embryos, this same gender stereotype has been increasingly incorporated into a legal balancing test, leading to troubling implications for ART and family law.

    Treffers, P E; Van den Berg, G R; Jager-van Gelder, P A; Van Oenen, J J

    1976-12-18

    156 women, 12-20 weeks pregnant, applied for abortion at the Wilhelmo Clinic in Amsterdam; 102 abortions were granted. The 156 late-abortion seekers were compared with 282 early-abortion seekers and 490 pregnant women. The late-abortion seekers were significantly younger (P .05). A significantly greater number of women over 30 applied for early abortion (P .001). Unmarried or divorced women were more likely to apply to abortion (P .001). Nulliparae applied more frequently for late abortion, compared to early-abortion seekers (P .001). Women with only one child were more likely to be in the pregnancy group (p .05), with 2 children in the early-abortion group (p .001). Women from Surinam and the Antilles were more likely to be in the early abortion group (p .001). Of the late-abortion seekers, 9 had medical indications. Many had psychosocial problems; 91 had problems with partner relations. In 24 cases the delay in seeking abortion was due to a doctor. An ambivalent attitude toward the abortion existed in 22 of the patients. 83% of the late-abortion seekers and 11.3% of the early-abortion seekers had previously had an abortion. The contraceptive use of the late-abortion seekers was not regular. 1.3% of the late-abortion seekers and 9.9% of the early-abortion seekers were using IUDs at the time of conception. PMID:1012384

  17. Cytoplasmic inheritance of organelles in brown algae.

    Motomura, Taizo; Nagasato, Chikako; Kimura, Kei

    2010-03-01

    Brown algae, together with diatoms and chrysophytes, are a member of the heterokonts. They have either a characteristic life cycle of diplohaplontic alternation of gametophytic and sporophytic generations that are isomorphic or heteromorphic, or a diplontic life cycle. Isogamy, anisogamy and oogamy have been recognized as the mode of sexual reproduction. Brown algae are the characteristic group having elaborated multicellular organization within the heterokonts. In this study, cytoplasmic inheritance of chloroplasts, mitochondria and centrioles was examined, with special focus on sexual reproduction and subsequent zygote development. In oogamy, chloroplasts and mitochondria are inherited maternally. In isogamy, chloroplasts in sporophyte cells are inherited biparentally (maternal or paternal); however, mitochondria (or mitochondrial DNA) derived from the female gamete only remained during zygote development after fertilization. Centrioles in zygotes are definitely derived from the male gamete, irrespective of the sexual reproduction pattern. Female centrioles in zygotes are selectively broken down within 1-2 h after fertilization. The remaining male centrioles play a crucial role as a part of the centrosome for microtubule organization, mitosis, determination of the cytokinetic plane and cytokinesis, as well as for maintaining multicellularity and regular morphogenesis in brown algae.

  18. Abortion in Sri Lanka: The Double Standard

    2013-01-01

    In Sri Lanka, women do not have access to legal abortion except under life-saving circumstances. Clandestine abortion services are, however, available and quite accessible. Although safe specialist services are available to women who can afford them, others access services under unsafe and exploitative conditions. At the time of this writing, a draft bill that will legalize abortion in instances of rape, incest, and fetal abnormalities awaits approval, amid opposition. In this article, I explore the current push for legal reform as a solution to unsafe abortion. Although a welcome effort, this amendment alone will be insufficient to address the public health consequences of unsafe abortion in Sri Lanka because most women seek abortions for other reasons. Much broader legal and policy reform will be required. PMID:23327236

    2004-01-01

    The inverse relationship between abortion and crime has spurred new research and much controversy. If the relationship is causal, then polices that increased abortion have generated enormous external benefits from reduced crime. In previous papers, I argued that evidence for a casual relationship is weak and incomplete. In this paper, I conduct a number of new analyses intended to address criticisms of my earlier work. First, I examine closely the effects of changes in abortion rates between ...

The issue of abortion counselling in Britain has undergone a number of discursive shifts in response to political manoeuvring and changing socio-legal framing of abortion. In partic...

  2. The abortion battle: the Canadian scene.

    Sachdev, P

    1994-01-01

    In January 1988 the Supreme Court of Canada struck down the country's archaic abortion law on the ground that it imposed arbitrary delays and unfair disparities in access to abortion across the country. Since then, the conservative government of Canada has made a few attempts to introduce a new abortion policy, but it did not get passed in the parliament because the revised bills failed to protect women's right to 'life, liberty, and security of the person' within the meaning of the Canadian Charter. Canada has been without an abortion law for over four years and there has been a wide range of provincial policies and confusion in the country. Despite the legal vacuum, Canadian women are not frenziedly having abortions. However, the militancy of the anti-abortion groups has steadily intensified with continued assault on a woman's right to make reproductive choices. Since no law, short of banning abortions altogether, is going to satisfy abortion opponents, the abortion battle will rage on in Canada. PMID:8065237

  3. Abortion in Iranian legal system: a review.

    Mahmoud Abbasi

    2014-02-01

    Full Text Available 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.

  6. Influence of A1 cytoplasmic substitution on the downy-mildew incidence of pearl millet.

    Yadav, O P; Manga, V K; Gupta, G K

    1993-12-01

    Large-scale cultivation of pearl millet [Pennisetum glaucum (L.) R. Br. F1 hybrids in India has led to increased incidence of downy-mildew (Sclerospora graminicola). There is concern that the A1 male-sterile cytoplasm used in all the hybrids released so far is responsible for this increase. The influence of A1 malesterile cytoplasm on downy-mildew incidence in pearl millet was studied by comparing the disease reaction of 40 pairs of F1 hybrids, each pair carrying respectively a1 male-sterile and normal B cytoplasm. Mean downy-mildew incidence was similar in the hybrids carrying either A1 male-sterile or B cytoplasm. The general combining ability of lines with and without A1 cytoplasm was found to be similar for downy-mildew incidence. These results indicated that in pearl millet A1 cytoplasm is not associated with increased downymildew incidence. The possible danger of using only one source of cytoplasm has been briefly discussed.

  7. Responses of alloplasmic (cytoplasm=Triticum timopheevii) and euplasmic wheats (Triticum aestivum) to photoperiod and vernalization.

    Ward, R W; Heyne, E G; Paulsen, G M

    1983-07-01

    Studies were conducted to determine the influence of the male sterility-inducing cytoplasm of Triticum timopheevii (Zhuk.) Zhuk. on response of several common winter wheat (T. aestivum L.) nuclear genotypes to photoperiod and vernalization. Comparative studies of cytoplasmic substitution lines provide information on the role of the cytoplasmic genetic mechanism in growth and development. In the case of cytoplasmic male sterility-based hybrid production systems, ubiquity of sterility-inducing cytoplasm in derived hybrids warrants thorough characterization of its influence on plant phenotype. Factorial combinations of cytoplasm (T. timopheevii and T. aestivum), nuclear genotype, and photoperiod or vernalization treatments were evaluated under hydroponic conditions in controlled environment chambers. Interaction of cytoplasm, photoperiod, and nuclear genotype was significant in one or more experiments for days to anthesis and potential spikelet number, and interaction of cytoplasm, vernalization, and nuclear genotype was significant for days to spike emergence. Long day length was associated with increased percentage seed set in one study, but interactions of photoperiod and cytoplasm were not detected for percentage seed set. Interactions involving cytoplasm and photoperiod or vernalization were interpreted as evidence of the existence of genetic factors in cytoplsam of T. timopheevii which alter photoperiod or vernalization responses of alloplasmic plants relative to responses exhibited by euplasmic plants. Since photoperiod and vernalization responses are critical to adaptation, T. timopheevii cytoplasm can alter adaptability of T. aestivum. The specific effect would be nuclear genotype dependent, and does not appear to be of a magnitude greater than that induced by nuclear genetic variability at loci conditioning photoperiod or vernalization responses or other adaptation-determining characteristics. Normal multilocation/year testing of alloplasmic hybrids should

It focuses on countries w...

  11. The abortion debate in South Africa.

    Rees, H

    1991-01-01

    Before 1975 abortion was illegal in South Africa unless the life of the mother was at risk. The Abortion and Sterilization Act (ASA) of 1975 broadened the scope of legal abortion. The act allows abortion to save the life of the mother, in cases of severe fetal deformity, in cases or rape or incest, or if the woman is mentally incompetent. The procedure to get the abortion includes finding a doctor to recommend the procedure, then finding 2 other doctors to claim, in good faith, that abortion is indicated. At least 1 of these doctors must have been practicing for 4 years and neither can participate in the procedure. The operation must take place in a state controlled institution or an institution specifically designed for abortion. This law is currently not serving the needs of the women of South Africa, even among the women who are legally entitled to have an abortion. Annually only 40% of those that apply for abortion are approved and over 70% of the approved procedures are performed on psychological grounds. It is estimated that there are 200,000-300,000 illegal abortions every year. At Baragwanath there are 15,000 patients admitted for infection related to abortion every year. The ASA has failed to stop illegal abortion and failed to meet the needs of society. The abortion law should be liberalized for a variety of reasons. Women do not have adequate access to contraceptives in South Africa. This results in the birth of many unwanted children which are more likely to be abused and abandoned. Even if contraceptives were universally available, they all have associated failure rates. Since it is assumed that a women using contraceptives does not want to become pregnant, abortion needs to be available as a backup to contraceptives. Since South Africa is a patriarchal society, women must be given control over their reproduction if they are to achieve equal status. Thus for the reasons of preventing unwanted and unwanted and abused children, backing up contraceptives

  12. Irish women who seek abortions in England.

    Francome, C

    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. PMID:1483530

  13. J-2X Abort System Development

    Santi, Louis M.; Butas, John P.; Aguilar, Robert B.; Sowers, Thomas S.

    2008-01-01

    The J-2X is an expendable liquid hydrogen (LH2)/liquid oxygen (LOX) gas generator cycle rocket engine that is currently being designed as the primary upper stage propulsion element for the new NASA Ares vehicle family. The J-2X engine will contain abort logic that functions as an integral component of the Ares vehicle abort system. This system is responsible for detecting and responding to conditions indicative of impending Loss of Mission (LOM), Loss of Vehicle (LOV), and/or catastrophic Loss of Crew (LOC) failure events. As an earth orbit ascent phase engine, the J-2X is a high power density propulsion element with non-negligible risk of fast propagation rate failures that can quickly lead to LOM, LOV, and/or LOC events. Aggressive reliability requirements for manned Ares missions and the risk of fast propagating J-2X failures dictate the need for on-engine abort condition monitoring and autonomous response capability as well as traditional abort agents such as the vehicle computer, flight crew, and ground control not located on the engine. This paper describes the baseline J-2X abort subsystem concept of operations, as well as the development process for this subsystem. A strategy that leverages heritage system experience and responds to an evolving engine design as well as J-2X specific test data to support abort system development is described. The utilization of performance and failure simulation models to support abort system sensor selection, failure detectability and discrimination studies, decision threshold definition, and abort system performance verification and validation is outlined. The basis for abort false positive and false negative performance constraints is described. Development challenges associated with information shortfalls in the design cycle, abort condition coverage and response assessment, engine-vehicle interface definition, and abort system performance verification and validation are also discussed.

    Previous research has convincingly shown that abortion legalization in the early 1970s led to a significant drop in fertility at that time. But this decline may have either represented a delay in births from a point where they were have represented a permanent reduction in fertility. We combine data from the 1970 U.S. Census and microdata from 1968 to 1999 Vital Statistics records to calculate lifetime fertility of women in the 1930s through 1960s birth cohorts. We examine whether those women...

  1. [Scope of the indications for abortion].

    Martella, E

    1976-09-01

    Legalization of abortion in Italy generates never ending discussions. The problem should have been solved years ago with a national campaign for family planning, with the setting up of well organized family centers, and with contraception available and free to all. If it seems right and proper to perform abortion under certain circumstances, it does not seem proper to take into consideration socioeconomic conditions, and certainly not abortion on request; a new life must not be wasted because a woman does not feel like having a new child. Abortion, on the other hand, is certainly to be considered in case of danger for the mother, in case of fetal abnormalities, or when the pregnancy is result of incest or of rape. Abortion for psychological reasons is very valid if the reasons are real, evident, and have been thoroughly evaluated. PMID:1012595

  2. Ultrasonographic findings of early abortion: suggested predictors

    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

  3. [Therapeutic abortion, unjustified absence in health policy].

    Chávez-Alvarado, Susana

    2013-07-01

    Although abortion for health reasons is not considered a crime in Peru, the State does not allow its inclusion in public policy, thus violating women's right to terminate a pregnancy when it affects their health. When examining the article in the Criminal Code which decriminalizes this type of abortion, provisions are identified which protect women and set the conditions to offer this type of service. This document sets the debate about the arguments used by the Peruvian State for not approving a therapeutic abortion protocol which would regulate the provision and financing of therapeutic abortion in public services, and explains why this obligation should be complied with, based on the conceptual framework of "health exception" In addition, it presents two cases brought before the judicial court in which the Peruvian State was found guilty of violating the human rights of two adolescents to whom a therapeutic abortion was denied.

    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%).

  5. Medical abortion: the hidden revolution.

    Harvey, Phil

    2015-07-01

    While the medical abortion (MA) drugs, mifepristone and misoprostol, have radically altered reproductive health practices around the world, there has been little field research on the sales and use of these drugs, especially in developing countries. This leaves the family planning community with many unanswered questions. While good profiles of contraceptive use are available for many countries and we have good technical data on the MA drugs' efficacy, dosages and regimens such as home dosage of misoprostol versus clinic dosage, we have very little information about the quantities of MA drugs sold, how they are used, where they are used, and, in the case of misoprostol, for what purposes. Sales data are available from one excellent commercial survey and from social marketing sales of mifepristone and misoprostol and these are presented. Acknowledging the sensitivity of the issue, especially in countries where abortion is severely restricted, the author makes a plea for careful additional research to shed light on an important and growing part of the international reproductive health picture.

  6. Reproductive rights: Current issues of late abortion

    Mujović-Zornić Hajrija

    2009-01-01

    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. .

  7. [Induced abortion: a vulnerable public health problem].

    Requena, M

    1991-03-01

    Induced abortion is an urgent public health problem that can be controlled if it is approached in its true complexity and with a social and humanist perspective. Induced abortion has been discussed in Chile since the last century, but not always openly. Abortion is not just an individual and collective medical problem, it is also an ethical, religious, legal, demographic, political, and psychological problem. Above all it is a problem of human rights. In the past 60 years, more than 50 countries representing 76% of the world population have liberalized their abortion legislation. Around 980 million women have some degrees of access of legal abortion. The magnitude of illegal abortion is difficult to determine because of the desire of women to hide their experiences. Estimates of the incidence of abortion in Chile made some 25 years ago are no longer valid because of the numerous social changes in the intervening years. The number of abortions in Chile in 1987 was estimated using an indirect residual method at 195,441, of which 90%, or 175,897, were induced. By this estimate, 38.8% of pregnancies in Chile end in abortion. Data on hospitalizations for complications of induced abortion show an increase from 13.9/1000 fertile aged women in 1940 to 29.1 in 1965. By 1987, with increased contraceptive usage, the rate declined to 10.5 abortions per 1000 fertile aged women. The cost of hospitalization for abortion complications in 1987, despite the decline, was still estimated at US $4.3 million, a large sum in an era of declining health resources. The problem of induced abortion can be analyzed by placing it in the context of elements affecting the desire to control fertility. 4 complexes of variables are involved: those affecting the supply of contraceptive, the demand for contraceptives, the various costs of fertility control measure, and alternatives to fertility control for satisfying various needs. The analysis is further complicated when efforts are made to

    Fossil cytoplasm is a new research topic of interest in paleobotany. Atomic force microscope (AFM) is a new technology applied widely in physics and biology; however, it is rarely used in paleontology. Here we applied AFM for the first time to study fossil cytoplasm. The results indicate that the fossil cytoplasm is heterogeneous and full of ultrastructures, just like extant cytoplasm, and that the application of AFM, especially in combination with other techniques, can reveal the subcellular details of fossil plants with more confidence.

  9. Ireland: child rape case undermines abortion ban.

    1992-11-01

    Abortion has been illegal in Ireland since 1861. This position was written into the national Constitution in 1963 and reconfirmed by referendum in 1983. Contraception is also illegal in the country. The pregnancy of a 14-year old adolescent due to an alleged rape, however, has caused many in Ireland to voice their support for abortion in limited circumstances. Approximately 5000 pregnant women go from Ireland to the United Kingdom annually for abortions. This 14-year old youth also planned to make the crossing, but was blocked from leaving by the Irish police and later by an injunction of the Attorney-General. The Irish Supreme Court upheld the injunction even though the young woman was reportedly contemplating suicide. A national outcry ensued with thousands of demonstrators marching in Dublin to demand the availability of information on abortion and that Irish women be allowed to travel whenever and wherever they desire. 66% of respondents to recent public opinion polls favor abortion in certain circumstances. Ultimately, the Irish Supreme Court reversed their stance to allow pregnant Irish women to travel internationally and gave suicidal Irish women the right to abortions. These decisions were made shortly within the time frame needed for the young lady in question to received a legal abortion in the United Kingdom. PMID:12222235

  10. Bills to decriminalize abortion in Brazil.

    1994-01-01

    The National Congress in Brazil is currently considering 9 abortion bills, 2 of which were introduced by women. In this interview, the women senators--Jandira Feghall of the Communist Party and Eva Blay of the Social Democrat Party--discuss the likely outcome of the abortion debate. Although the Roman Catholic Church has announced its intentions to oppose any liberalization of the abortion law, there are divisions within the Church as evidenced by the existence of groups such as Catholics for a Free Choice. Both senators agree that decriminalization of abortion will depend upon the societal response and an effort must be made to reach the many people who are confused and undecided about the issue. Although the present debate fits within the broader current debate on population policies, it has been the insistence of the feminist movement that put abortion reform on the agenda. Blay's bill calls for the legalization of abortion on demand until the 12th week of pregnancy and in cases of rape or risk to the woman's life after that point. A controversial aspect of Feghall's bill is the inclusion of maternal human immunodeficiency virus (HIV) infection as a condition for abortion. Feghall notes that this is an option rather than a requirement, but she will eliminate this condition if it engenders discrimination against HIV-infected women. PMID:12318722

  13. SOCIO-DEMOGRAPHIC PROFILES OF SEPTIC ABORTION

    Manoj

    2014-05-01

    Full Text Available INTRODUCTION: Septic abortion is a significant contributor to maternal morbidity and mortality. Termination of pregnancy, although a safe and easy procedure in trained hands, can produce catastrophic outcomes when performed by unauthorized or untrained people and in improper settings. OBJECTIVE: To find out the association of various socio-demographic factors with septic abortion. MATERIAL AND METHODS: This was a longitudinal study, conducted in the indoor of obstetrics & gynaecology department of R.M.C.H & R.C, Ghaziabad district of Uttar Pradesh from the period of Feb-2013 to April-2013, after selecting 100 septic abortion cases by simple randomization, who were admitted during the study period. Information of all these cases regarding their age, marital status, socio-economic status, literacy, parity and gestational age was obtained, and their association with septic abortion was studied accordingly. OBSERVATION: Out of the 100 cases of septic abortion studied, maximum percentage (66% of the cases was seen from the age group of 26 to 35 years. Most of the cases (97% were married, maximum (40% were belonging from low socio-economic status group (Group-IV, maximum (60% number of cases were illiterate, maximum (53% number of cases belonged to women group having parity five and above, and maximum (86% number of women were in the 1st trimester of pregnancy at the time of abortion. CONCLUSION: Present study confirms that unsafe abortion is one of the greatest neglected healthcare problems in India and more so in rural India. So, there is the need to strengthen quality abortion services to reduce the maternal morbidity and mortality due to septic abortion

  14. The abortion debate: measuring gestational age.

    Santee, B; Henshaw, S K

    1992-01-01

    Abortion statistics are flawed by the lack of consistency in reporting gestational age. Several methods are generally used, and the number of abortions occurring before 12 weeks changes considerably depending upon the method used to determine gestational age. Pregnancy can be measured from the beginning of last menstruation or from fertilization, which is 14 days after the 1st day of the last menstrual period. Neither method accurately records pregnancy as determined by specialists in embryology and fetal development. Pregnancy actually begins with implantation, which begins 6-7 days after fertilization and ends 10-14 days later. Completion of fertilization and implantation occurs as much as 28 days after the 1st day of the last menstrual period. A report of an 8-week pregnancy is actually 6 weeks from fertilization and 4-5 weeks from implantation. The Centers for Disease Control and other abortion data collecting agencies use the 1st day of the last menstrual period. Statistics generally show that 50% of abortions occur before 8 weeks of gestation and 90% by 12 weeks. When gestation is considered at fertilization, 78% of abortions occur under 9 weeks, while 52% of abortions under 9 weeks are performed with data beginning at the 1st day of the last menstrual period. For abortions occurring under 12 weeks, 95% beginning at fertilization and 90% occur at the 1st day of the last menstrual period. 2/1000 vs. 5/1000 abortions occur under 20 weeks for data beginning at fertilization vs. at the onset of the last period. It is important to report abortion data accurately and to specify the method used to determine the gestational time period. PMID:1526273

  15. Radical surgery in septic abortion.

    Chatterjee, P; Ghosh, M; Ghosh, S

    1979-08-01

    At R.G. Kar Medical College Hospital, Calcutta, 10 cases of septic abortion from 1975-1977 were studied. Hysterectomies were preformed on 4 cases due to emergency situations including traumatised uterine fundus and perforated cervix, and on 6 cases after conservative treatment. Upon performing laparotomy in 9 cases, a uterine rent was detected; in 1 case there was a perforation in the posterior wall of the cervix, and in 5 cases mechanical obstructions due to internal adhesions to the uterine rent were found. 4 patients died primarily because of the patients seeking help too late. It is suggested that under high risk circumstances, laparotomy is advantageous to conservative medical management since bowel injuries and mechanical obstructions can only be detected by laparotomy. Radical surgery, however, should be undertaken before the patients general condition deteriorates to the point that the patient cannot tolerate surgical intervention. PMID:12336028

  16. How technology is reframing the abortion debate.

    Callahan, D

    1986-02-01

    Since the 1973 Supreme Court decision legalizing abortion, medical and scientific developments have focused greater public and professional attention on the status of the fetus. Their cumulative effect may influence legal, social, and moral thought and set the stage for a change in public opinion and a challenge to legalized abortion. There is as yet no inexorable convergence of medical data and legal opinion that would undermine the rational of Roe v. Wade. But the prochoice movement must find room for an open airing of the moral questions if abortion is to remain what it should be--a legally acceptable act. PMID:3514547

    To minimise 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.

  20. Public opinion about abortion-related stigma among Mexican Catholics and implications for unsafe abortion.

    McMurtrie, Stephanie M; García, Sandra G; Wilson, Kate S; Diaz-Olavarrieta, Claudia; Fawcett, Gillian M

    2012-09-01

    A nationally representative survey was conducted among 3000 Catholics in Mexico during 2009 and 2010. Respondents were presented with a hypothetical situation about a young woman who decided to have an abortion and were asked their personal opinion of her. On the basis of a stigma index, it was found that the majority (61%) had stigmatizing attitudes about abortion; however, 81% believed that abortion should be legal in at least some circumstances. Respondents were significantly more likely to stigmatize abortion if they disagreed with the Mexico City law legalizing the procedure (odds ratio 1.66; 95% CI, 1.30-2.11) and believed that abortion should be prohibited in all cases (odds ratio 3.13; 95% CI, 2.28-4.30). Such stigma can lead women to seek unsafe abortions to avoid judgment by society. PMID:22920621

    This document summarizes a sample of significant activities and events undertaken by Roman Catholics in response to the US Supreme Court's Roe vs. Wade decision legalizing induced abortion. The summaries begin with the 1966 creation of the National Right to Life Committee and cover opposition of Catholic bishops to the Roe decision, the organization of the National Committee for a Human Life Amendment (NCHLA), the mock investiture of a female pope by Catholics for a Free Choice, dismissal of a pro-life priest from the Jesuits, excommunication of various women because of their work with pro-choice agencies or ones that provided abortion services, meetings of the National Conference of Catholic Bishops (NCCB) with presidential candidates, NCHLA lobbying for the Hyde Amendment, open letters and advertisements published by CFC, the effort of Abortion Rights Mobilization to strip the Catholic church of its tax-exempt status, the Vatican order for all priests to leave political office, actions taken by nuns to support the pro-choice position, the proposal of the "seamless garment" argument under the principle of the "consistent ethic of life," initiation of the post-abortion reconciliation project, the actions of Catholic politicians, the filing of amicus curiae briefs, support of bishops for Operation Rescue, forums on abortion conducted by an Archbishop, the Catholic Statement on Pluralism and Abortion, targeting by bishops of pro-choice candidates for sanctions and excommunication, testimony and lobbying in opposition of the Freedom of Choice Act, false accusations about the 1994 International Conference on Population and Development leveled by bishops, lobbying by bishops in support of a ban on late-term abortions, lobbying to increase the access of low-income women to abortion, and consideration by the bishops of reinstituting "meatless Fridays" to express Catholic opposition to "attacks on human life and dignity."

As such, there is no legal barrier for the decriminalization of abortion in...

  10. South African parliament approves sweeping abortion reform.

    1996-11-22

    South Africa's National Assembly voted 209 to 87 for passage of the "Choice on Termination of Pregnancy Act" on October 30; it was passed in the Senate, 49 to 21 (20 abstentions), on November 5. The African National Congress strongly supported the Act, while the National Party opposed it. Under the law, abortions during the first 12 weeks of pregnancy may to be performed by physicians or trained midwives. From week 13 through week 20, a physician, in consultation with the mother, may terminate the pregnancy after determining that continuing the pregnancy would threaten the woman's health (physical or mental) or circumstances (social or economic), or that the fetus is at substantial risk of suffering severe physical or mental abnormalities. Abortion is permitted after 20 weeks if two doctors (or midwives) decide continuing the pregnancy would endanger the mother's life or result in injury or severe malformation of the fetus. Only the pregnant woman's consent is required. Although an abortion provider must advise a young client to consult with parents, guardian, family members, or friends before the procedure, she is not required to comply. All women are to be informed of their rights under the Act; criminal penalties (up to 10 years) are mandated for unauthorized abortion providers, for persons who prevent a lawful abortion, or for those who obstruct access to an abortion facility. The new statute repeals the more restrictive Abortion and Sterilization Act of 1975, which permitted abortion only in cases of maternal life or health endangerment, severe fetal abnormality, rape, incest, or mental incapacity. PMID:12292092

  11. Abortion and anxiety: what's the relationship?

    Steinberg, Julia Renee; Russo, Nancy F

    2008-07-01

    Using data from the United States National Survey of Family Growth (NSFG) and the National Comorbidity Survey (NCS), we conducted secondary data analyses to examine the relationship of abortion, including multiple abortions, to anxiety after first pregnancy outcome in two studies. First, when analyzing the NSFG, we found that pre-pregnancy anxiety symptoms, rape history, age at first pregnancy outcome (abortion vs. delivery), race, marital status, income, education, subsequent abortions, and subsequent deliveries accounted for a significant association initially found between first pregnancy outcome and experiencing subsequent anxiety symptoms. We then tested the relationship of abortion to clinically diagnosed generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD), and social anxiety disorder, using NCS data. Contrary to findings from our analyses of the NSFG, in the NCS analyses we did not find a significant relationship between first pregnancy outcome and subsequent rates of GAD, social anxiety, or PTSD. However, multiple abortions were found to be associated with much higher rates of PTSD and social anxiety; this relationship was largely explained by pre-pregnancy mental health disorders and their association with higher rates of violence. Researchers and clinicians need to learn more about the relations of violence exposure, mental health, and pregnancy outcome to avoid attributing poor mental health solely to pregnancy outcomes.

  12. The abortion debate in the Dominican Republic.

    1992-01-01

    Faced with a situation in which an estimated 60,000 illegal abortions (a major cause of maternal mortality) were performed annually, the Dominican Republic has adopted a new Health Code which contains a chapter dedicated to maternal health. Included in the new code are cases in which abortion is allowed: 1) when 2 specialists affirm that the pregnancy or childbirth constitutes a risk to the mother's health or life; 2) if the medical history of the parents and 2 doctors confirm the likelihood of the baby being born seriously disabled or deformed; or 3) if the mother's mental health is put in jeopardy by continuing the pregnancy. Despite the disapproval of church representatives, the legalization of abortion was unanimously approved by the Congress. The debate which surrounded the process was increased by a petition signed by more than 260 women decrying the lack of input that women had in the decision-making process. Women's action groups have been trying to widen the context in which the political discussion is taking place to stress the importance of viewing abortion from a reproductive rights perspective. The women's groups wish to prevent a situation in which the discussion surrounding the issue will be limited to legislators and church leaders. The women have pointed out that women should make the decisions about their lives and their bodies. In the meantime, the president of the Congress predicts that illegal abortion will continue in the Dominican Republic regardless of the current provisions for legal abortion. PMID:12286344

    Full Text Available Aim of this study was to study the incidence, demographic factors, clinical features, management, maternal morbidity, maternal mortality, surgical interventions with special emphasis on various contributing factors and unmet needs of septic abortion. In this study, 153 cases of septic abortions during six years periods, from January 2009 to December 2014 in the department of obstetrics and gynecology in Rajendra Institute of Medical Sciences, Ranchi, were included. All patients were evaluated with special reference to incidence, age incidence, marital status, socio economic status, residential distribution, gravida incidence, causes of septic abortion, grades of infection, clinical presentation, and management. Incidence of septic abortion was 3.88 % . Criminal interference was in 74 % of cases. Most of the cases (65 % were from low socioeconomic group. Sixty percent were from rural area. Fifty eight percent were tribal. Sixteen percent were admitted in septic shock. Laparotomy was required in seventeen percent of cases. Hysterectomy was require in five cases. Unfortunately, maternal death was nine. Cause of maternal death was septic shock in six and haemorrhagic shock in three. This incidence of septic abortion can be reduced by increasing awareness and making “safe abortion services” easily available, free of coast and also by providing family planning services.

  15. Abortion in Vietnam: measurements, puzzles, and concerns.

    Goodkind, D

    1994-01-01

    This report summarizes current knowledge about abortion in Vietnam, drawing upon government statistics, survey data, and fieldwork undertaken by the author in Vietnam throughout 1993 and part of 1994. The official total abortion rate in Vietnam in 1992 was about 2.5 per woman, the highest in Asia and worrisome for a country with a still-high total fertility rate of 3.7 children per woman. Vietnamese provinces exhibited substantial variation in both the rate of abortion and the type of procedures performed. Among the hypotheses explored to explain Vietnam's high rate of abortion are the borrowing of family planning strategies from other poor socialist states where abortion is common; current antinatal population policies that interact with a lack of contraceptive alternatives; and a rise in pregnancies among young and unmarried women in the wake of recent free-market reforms. Because family-size preferences are still declining, abortion rates may continue to increase unless the incidence of unwanted pregnancy can be reduced, a goal that Vietnamese population specialists are seeking to achieve.

    2006-01-01

    Full Text Available This study aimed to identify the factors associated with induced abortion in the first pregnancy in young women and in the first time young men got their partners pregnant. The methodology was a household survey with face-to-face interviews in a probabilistic sample in three stages with 4,634 subjects, aged 18 to 24 years of age residing in the cities of Salvador, Rio de Janeiro, and Porto Alegre, Brazil. Logistic regression analysis was used with a hierarchical strategy for entering variables into the model. Abortion was the reported outcome of the first pregnancy for 16.7% of the women and 45.9% of the men (in relation to their partners. Key factors associated with abortion included higher schooling and the occasional nature of the relationship with the male or female partner in the respective pregnancy. Inclusion of males in the study provided new elements for understanding the abortion phenomenon, including in the gender issues in discussion of the theme. The authors recommend greater public investment to warrant access to information and means for young people to achieve their reproductive plans in a security and healthy way, respecting their sexual and reproductive rights.

  17. Differences in Nuclear DNA Between Male-Sterile and Male-Fertile Lines of Sorghum bicolor

    Cytoplasmic male sterility (cms) is determined by nuclear-cytoplasmic interactions. Up tonow, most studies are focused on the comparison of cytoplasmic DNAs of male-sterile lines and male-fertilelines, and analysis of nuclear DNA has not been documented yet. In order to find out the possible difference innuclear genome of male-sterile line A1 Tx623 and corresponding male-fertile line Tx623 of sorghum, randomamplified polymorphic DNA (RAPD) approach was used to analyze their cytoplasmic and nuclear genomes.Total DNAs of them were amplified at first to screen primers, which were able to generate reproducible bandsspecific to male-sterile line or male-fertile line. Then the selected primers were used to amplify their mitochon-drial DNA (mtDNA) and chloroplast DNA (cpDNA). The origins of all the polymorphic fragments were ana-lyzed. After ruling out those amplified from cytoplasmic DNA, seventeen polymorphic fragments were deter-mined to be amplified from nuclear DNA. These fragments originated from nuclear DNA indicate that diffe-rences in sequence exist between the nuclear DNA of male-sterile line and male-fertile line of sorghum, whichdo not agree with the traditional standpoint that they have identical nucleus.

  18. Unsafe abortion and postabortion care-An overview

    Rasch, Vibeke

    2011-01-01

    Forty percent of the world's women are living in countries with restrictive abortion laws, which prohibit abortion or only allow abortion to protect a woman's life or her physical or mental health. In countries where abortion is restricted, women have to resort to clandestine interventions to have...... an unwanted pregnancy terminated. As a consequence, high rates of unsafe abortion are seen, such as in sub-Saharan Africa where unsafe abortion occurs at rates of 18-39/1 000 women. The circumstances under which women obtain unsafe abortion vary and depend on traditional methods known and type of...... providers present. Health professionals are prone to use instrumental procedures to induce the abortion, whereas traditional providers often make a brew of herbs to be drunk in one or more doses. In countries with restrictive abortion laws, high rates of maternal death must be expected and globally an...

  19. [Glimpses from the history of abortion].

    Holmdahl, B

    1992-05-01

    For a long time in human history, global population growth was checked by infant mortality, which ranged from 30-50% and did not start sinking until the beginning of the 1800s in the west. Child murder in the west was prohibited by law around the 1100-1200s, but it continued secretly. Among private people, induced abortion was allowed. In the holy scripts of Hinduism and Brahminism, abortion was prohibited. Hippocrates wrote that doctors should not give women abortifacient. The church father Augustinus stated that it was not within human power to discern when the soul entered the body, a circumstance that forbid abortion. A church meeting in 305 A.D. distanced itself from abortion, and this has been the stand of the Catholic Church ever since. In Sweden, exposing a child to the elements was practiced until the end of the 1200s, when it became prohibited. Protestants punished child murder by death. During 1759-78, 217 women were executed for child-killing. From the 1400s, church law punished abortion, and later, capital and punishment was meted out for it, but a distinction was made if the fetus was alive or stillborn. The law in 1734 punished abortion by the death of all concerned. The death penalty was abolished in 1864. In 1896, Anna Linholm reported to the policy in Uppsala that a midwife had been practicing clandestine abortions. Some of her patients were admitted to hospital for hemorrhaging. She was sentenced to hard labor. During 1851-1903, a total of 1408 abortions were reported to the health service. 90% of these became known because of death caused by obduction. Phosphorus was used for abortion in 1271 cases, arsenic in 62, and mechanical aids in 8 cases. About 1//2 of all female suicides at the end of the 1800s was performed by pregnant women who ate phosphorus. Almost all were unmarried, and 56% carried it out after the 5th month of pregnancy. In 1901, phosphorus was prohibited in Swedish homes. In 1875, free abortions became available. However, the

  20. Women's Private Conversations about Abortion: A Qualitative Study.

    Herold, Stephanie; Kimport, Katrina; Cockrill, Kate

    2015-01-01

    Abortion is a relatively frequent experience, yet public discourse about abortion is contentious and stigmatizing. Little literature is available on private conversations about abortion, which may be distinct from public discourse. We explored private discourse by documenting the nature of women's discussions about abortion with peers in a book club. We recruited thirteen women's book clubs in nine states. Participants (n = 119) read the book Choice: True Stories of Birth, Contraception, Infertility, Adoption, Single Parenthood, & Abortion, and participated in a book club meeting, which we audio-recorded and transcribed. Data collection occurred between April 2012 and April 2013. In contrast to public discourse of abortion, private discourse was nuanced and included disclosures of multiple kinds of experiences with abortion. Participants disclosed having abortions, considering abortion as an option for past or future pregnancies, and supporting others through an abortion. Distinguishing between public and private discourse enabled us to identify that an "abortion experience" could include personal decisions, hypothetical decisions, or connection with someone having an abortion. The book club atmosphere provided a rare opportunity for participants to explore their relationship to abortion. More research is needed to understand the role of private discourse in reducing abortion stigma. PMID:26086582

  1. [Conscientious objection in the matter of abortion].

    Serrano Gil, A; García Casado, M L

    1992-03-01

    The issue of conscientious objection in Spain has been used by pro-choice groups against objecting health personnel as one of the obstacles to the implementation of the abortion law, a misnomer. At present objection is massive in the public sector; 95% of abortions are carried out in private clinics with highly lucrative returns; abortion tourism has decreased; and false objection has proliferated in the public sector when the objector performs abortions in the private sector for high fees. The legal framework for conscientious objection is absent in Spain. Neither Article 417 of the Penal Code depenalizing abortion, nor the Ministerial Decree of July 31, 1985, nor the Royal Decree of November 21, 1986 recognize such a concept. However, the ruling of the Constitutional Court on April 11, 1985 confirmed that such objection can be exercised with independence. Some authors refer to the applicability of Law No. 48 of December 16, 1984 that regulates conscientious objection in military service to health personnel. The future law concerning the fundamental right of ideological and religious liberty embodied in Article 16.1 of the Constitution has to be revised. A draft bill was submitted in the Congress or Representatives concerning this issue on May 3, 1985 that recognizes the right of medical personnel to object to abortion without career repercussions. Another draft bill was introduced on April 17, 1985 that would allow the nonparticipation of medical personnel in the interruption of pregnancy, however, they would be prohibited from practicing such in the private hospitals. Neither of these proposed bills became law. Professional groups either object unequivocally, or do not object at all, or object on an ethical level but do not object to therapeutic abortion. The resolution of this issue has to be by consensus and not by imposition. PMID:1565971

  2. Abortion in Brazil: legislation, reality and options.

    Guedes, A C

    2000-11-01

    Abortion is illegal in Brazil except when performed to save the woman's life or in cases of rape. This paper gives a brief history of parliamentary and extra-parliamentary efforts to change abortion-related legislation in Brazil in the past 60 years, the contents of some of the 53 bills that have been tabled in that time, the non-governmental stakeholders involved and the debate itself in recent decades. The authorities in Brazil have never assumed full public responsibility for reproductive health care or family planning, let alone legal abortion; the ambivalence of the medical profession is an important obstacle. Most politicians avoid getting involved in the abortion debate, but the majority of bills in the 1990s have favoured less restrictive legislation. Incremental legislative and health service changes could help to improve the situation for women. Advocacy is probably the most important action, to promote an environment conducive to change. Clandestine abortion is a serious public health problem in Brazil, and the inadequacy of family planning services is one of the causes of this problem. The solutions should be made a priority for the Brazilian public health system. PMID:11424252

  3. Access to abortion services: abortions performed by mid-level practitioners.

    Kowalczyk, E A

    1993-01-01

    Because the number of physicians available to perform abortions in the US is dwindling, certified nurse-midwives, nurse practitioners, and physician assistants should be trained and permitted to perform abortions. Roadblocks to this change are the fact that the Supreme Court would likely allow states to prevent mid-level practitioners from performing abortions in the name of protecting the health of the mother. Also, existing statutes would probably not be interpreted by courts to allow mid-level practitioners to perform abortions. However, physician assistants have been performing abortions in Vermont since 1975, and a 1981-82 comparative study affirmed that physician assistants are well-equipped to perform abortions (of 2458 procedures, the complication rate/1000 was 27.4 for physician assistants and 30.8 for physicians). However, controversy surrounds the provision of abortion by these physician assistants in Vermont, since the relevant statute suggests that abortion is illegal unless performed by a physician. However, the statute has not been changed since Roe vs. Wade and is likely unconstitutional. Court cases in Missouri and Tennessee suggest that courts may be willing to include abortion within the scope of progressive nursing practice acts, but a recent similar case in Massachusetts resulted in a narrow interpretation of nursing practice statutes. Because the definition of professional nursing varies with each state statute, it will be a formidable task to convince every jurisdiction to include abortion as a permissible mid-level practice. Even in Vermont, the nursing practice statute defines in an exclusive list what services the professional nurse may perform (whereas the physician assistant regulations limit their scope of practice only to that delegated by a supervising physician). States could, of course, pass statutes which include abortion as a permissible practice for the mid-level practitioner. However, specific legislation would provide a clear

    2007-01-01

    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.

    Six-Quivy, M; Macaigne, M; Playoust, D; Zylberberg, G

    1980-01-01

    The French law legalizing abortion provided for a meeting between patient and social counselor prior to the intervention. Aim of this provision was to allow a women to see more clearly into herself, and to allow a social worker to help the patient make a personal and wise decision. Most women come to this encounter with feelings of guilt, anxiety, and depression; most of them want abortion because they know they can have one, and medical reasons for abortion are practacally nonexistant. The emotional situation of the couple, more than their socioeconomic condition, does have a great importance in making a final decision. A discussion can sometimes help, but the responsibility of the decision is with the women's alone. PMID:7401902

  8. Medical abortion. defining success and categorizing failures

    Rørbye, Christina; Nørgaard, Mogens; Vestermark, Vibeke;

    2003-01-01

    Medical abortion was performed in 461 consecutive women with gestational age LT /= 63 days using a regimen of mifepristone 600 mg followed 2 days later by gemeprost 1 mg vaginally. Success, defined as no surgical intervention, declined from 98.7% after 2 weeks to 94.6% after 15 weeks. The...... difference in short- and long-term success rates increased with increasing gestational age. The majority of failures (76%) were diagnosed more than 2 weeks after initiation of the abortion. At a 2-week follow-up visit, the women who turned out to be failures had a larger endometrial width, higher beta......-hCG values and smaller reductions of beta-hCG than those treated successfully. To optimize comparison of success rates after different medical abortion regimens, we suggest that the criteria for success are stated clearly, that the success rates are stratified according to gestational age and that the...

  9. Diagnostic categorization of post-abortion syndrome.

    Gómez Lavín, C; Zapata García, R

    2005-01-01

    Some psychopathological characteristics are frequently observed in women who have voluntarily aborted. However, some resistance currently remains to their recognition as a differentiated nosological category, known as Post-Abortion Syndrome (PAS). We tried to assign a diagnostic category to women with PAS by determining the extent by which they fulfilled the diagnostic criteria of international classifications. Criteria for Post-Traumatic Stress Disorder (PTSD) were met in the ten PAS cases studied. In addition, patients also showed other non-specific symptoms such as repeated and persistent dreams and nightmares related with the abortion, intense feelings of guilt and the "need to repair". PAS should be considered as an additional type of PTSD. It also has some specific characteristics that could help to understand the patient's life experience and to establish a psychotherapeutic intervention. PMID:15999304

  10. Access to abortion and secular liberties

    Roberto Arriada Lorea

    2007-01-01

    Full Text Available In Brazil, facing an issue like abortion requires a secular perspective since the freedom of conscience assured by the Federal Constitution places upon the State the need to regard not only different viewpoints of different religions, but more specifically assure the right to diversity existing within a same religion, as well as the right to exercise different views from those of the hierarchy of his/her own religion. As such, there is no legal barrier for the decriminalization of abortion in the country. It is up to legislators to reform the present law and decriminalize abortion, assuming the commitments Brazil has assumed with international human-rights organizations, thus assuring the efficacy of civil liberties.

  17. Development of abort trigger system for SuperKEKB

    We have developed the new abort trigger system for SuperKEKB. The abort trigger system collects more than 130 abort signals and issues the abort kicker trigger signal. Since the response time of the system is required to be less than 20 μs, the abort signals are transmitted as optical signals. The system also has the timestamp function to record the abort signal received time with a 0.1 μs time resolution. Based on the performance tests, the response time of the modules is considered to be much shorter than cable delay. In the new system, the timestamp information gives the order of the received abort signals. This paper describes the design and the result of the performance test of the new abort trigger system.

  20. Catholic options in the abortion debate.

    Maguire, D C

    1990-01-01

    The little-known Roman Catholic theological doctrine of probabilism, an ethical system explicated in all manuals of moral theology, is explained using as an example the dilemma of abortion. Probabilism is based on the notion that a doubtful moral obligation may not be imposed as though it were certain. "Ubi dubium, ibi libertas," means where there is doubt, there is freedom. There are 2 types of moral probability, intrinsic probability, where the individual, without the help of moral theologians, perceives the inapplicability of a particular moral teaching; and extrinsic probability, which involves reliance on the findings of 5 or 6 reputable moral theologians, who may hold a liberal view. Probabilism implies a reasonable doubt, and one's reasons must be cogent, but not necessarily conclusive. Today's abortion debate is an example of a respectable debate, where the liberal view has been endorsed by a number of reputable religious or other humanitarian bodies that in some cases abortion is not always immoral. Other examples in history are the view once taught by the church that taking interest on loans was immoral, that depriving slaves and women of civil rights on non-Catholics of religious or political freedom was moral. For today's legislators, there is a precedent throughout theological history for the state permitting an evil: both St. Augustine and St. Thomas Aquinas wrote that prostitution, although evil, should not be outlawed, because worse evils would occur with prohibition. Legislators who personally find abortion always immoral can support a Roe V. Wade decision because 1) it does not require anyone to have an abortion, and 2) the abortion debate, among Catholics, and non-Catholics is not settled. PMID:12178838

  1. Misoprostol and illegal abortion in Fortaleza, Brazil.

    Coêlho, H L; Teixeira, A C; Santos, A P; Forte, E B; Morais, S M; La Vecchia, C; Tognoni, G; Herxheimer, A

    1993-05-15

    Misoprostol, a prostaglandin E1 analogue indicated for ulcer treatment, has been widely used as an abortifacient by women in Brazil, where abortion is legal only in cases of rape or incest, or to save the woman's life. Because misoprostol is an inefficient abortifacient, many women who use it have incomplete abortions and need uterine evacuation. We reviewed the records of women admitted to the main obstetric hospital of Fortaleza, capital of Ceará state, Brazil, between January, 1990, and July, 1992, for uterine evacuation after induced abortion. The number of incomplete abortions induced by misoprostol increased substantially during the first half of 1990, and declined thereafter. Of the 593 cases in 1991, 75% were related to misoprostol, 10% to the use of other specified drugs, and 6% to unspecified drugs. For the remaining 9% the procedure used was not recorded; these included 3% in whom abortion had been induced by a clandestine abortionist. The number of uterine evacuations per month fell from 89 in August, 1990, to 62 in July, 1991, when sales of misoprostol in Ceará state were suspended. The fall continued after the sale of misoprostol ceased, to about 20 cases in December, 1991; numbers remained around this level until June, 1992, sustained by clandestine sales. The lack of access to contraception is the main reason for the large numbers of unplanned pregnancies and is a major public health issue for Brazilian women. The prohibition of abortion creates a void in which misuse of medicines is one extra complication, mainly because of the poor control of drug marketing. PMID:8098403

    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

    2012-01-01

    How do abortion costs affect non-marital childbearing? While greater access to abortion has the first-order effect of reducing childbearing among pregnant women, it could nonetheless lead to unintended consequences via effects on marriage market norms. Single motherhood could rise if lower-cost abortion makes it easier for men to avoid marriage. We identify the effect of abortion costs on separation, cohabitation and marriage following a birth by exploiting the "miscarriage-as-a-natural exper...

    2014-01-01

    Objective The relation between levels of contraceptive use and the incidence of induced abortion remains a topic of heated debate. Many of the contradictions are likely due to the fact that abortion is the end point of a process that starts with sexual activity, contraceptive use (or non-use), followed by unwanted pregnancy, a decision to terminate, and access to abortion. Trends in abortion rates reflect changes in each step of this process, and opposing trends may cancel each other out. Thi...

Although abortion itself is a relatively minor, safe procedure with minimal physical impact, controversy exists regarding the psychological risks associated with the termination of a pregnancy. A key argument within this debate is whether or not there is such a phenomenon as post-abortion syndrome. Therefore, this study aimed to examine t...

  9. [Religion, morality and politics: the abortion debate].

    Ladriere, P

    1982-01-01

    The views of morality enunciated by the Protestant and Catholic churches in the process of France's abortion law revision are examined through an analysis of the testimony of each church and its moral theologians during hearings held from July-November 1973 by the Commission of Cultural, Family, and Social Affairs of the National Assembly concerning the proposed abortion legislation. The offical Catholic Church position, which restated a neoscholastic philosophy with its theory of human nature, natural law, natural right, and natural morality, was opposed by 2 priests who participated as members of other organizations. The moral principles behind the official Catholic position included the sacred and absolute principle of respect for life, the beginning of human life at conception, and the responsibility to protect the fetus as a human being. Internal Catholic challenges to the official position appeared to rest principally on the question of when life begins but also touched on the inappropriateness of viewing unwanted pregnancy as a punishment for sexual activity, the constant recourse to authority of the church, and the reluctance to reexamine questions on new evidence. Faced with the likely replacement of abortion law consistent with Catholic morality by 1 seriously at variance, the French Church and state while justifying their organized opposition to any change. The right of the church to impose its views on the legislature and on society, the view of the cultural context of abortion as a degradation of public attitudes expressed in rejection of children, the necessary connections between sexuality and fertility, the necessity for women to be able to control their fertility if they were to participate fully in society, the debased conditions in which thousands of illegal abortions occurred or the exaggeration of such conditions were other issues. Proposed legislation on abortion was opposed by the official Catholic position, which instead called for a vaguely

    2000-01-01

    Existing studies of physical strain and spontaneous abortion are mainly retrospective or based only on pregnancies that have survived the first trimester. Furthermore, almost all studies have relied on averaged measures of physical strain, which tend to blur an effect if peak values during short...... pregnancy the women recorded physical strain prospectively in a structured diary. Physical strain around the time of implantation was associated with later spontaneous abortion. The adjusted risk ratio for women who reported physical strain higher than average at day 6 to 9 after the estimated date of...

    Francome, Colin

    1980-01-01

    This research analyses the social and political forces underlying the 1aws of abortion in Britain and the United States. It sets out to explain the apparent paradox that the United States now has an abortion law which is more liberal than Britain despite the fact that in many ways it is a more conservative society. Furthemore it aims to set this recent situation in a historical context and to examine recent and likely future developments. It analyses the major social forces on either si...

  12. A comment on Tooley's Abortion and Infanticide.

    Tushnet, Mark; Seidman, Louis Michael

    1986-01-01

    Tushnet and Seidman attempt to show that, even if Michael Tooley is correct that fetuses have no right to life, others may have a right to their continued existence. Rights-bearing third parties with an interest in the fetus might be biological fathers, prospective adoptive parents, or even society as a whole. Criteria for assessing the legitimacy of claims of interest must be developed and then balanced against the claims of those who support abortion. The authors also discuss principles of bodily autonomy, the destruction as well as the removal of the fetus, and the question of whether legislation prohibiting abortion is mandatory, permissible, or optional.

  13. Acute pancreatitis following medical abortion: Case report

    Amini Hashem

    2004-04-01

    Full Text Available Abstract Background Acute pancreatitis rarely complicates pregnancy. Although most pregnant women with acute pancreatitis have associated gallstones, less common causes such as drugs have been reported. Case presentation We report the case of a 34-year-old woman who underwent medical abortion with mifepristone and gemeprost and received codeine as pain-relief during the induction of abortion. She developed a severe acute necrotizing pancreatitis which required 14 days of intensive care. Other possible etiological factors, i.e. gallstone, alcohol intake and hyperlipidemia, were excluded. Conclusions The reported case of acute pancreatitis was most likely drug-induced.

  20. Consequences of Cytoplasmic Irradiation: Studies from Microbeam

    Zhou, Hongning; Hong, Mei; Chai, Yunfei; Hei, Tom K.

    2013-01-01

    The prevailing dogma for radiation biology is that genotoxic effects of ionizing radiation such as mutations and carcinogenesis are attributed mainly to direct damage to the nucleus. However, with the development of microbeam that can target precise positions inside the cells, accumulating evidences have shown that energy deposit by radiation in nuclear DNA is not required to trigger the damage, extra-nuclear or extra-cellular radiation could induce the similar biological effects as well. This review will summarize the biological responses after cytoplasm irradiated by microbeam, and the possible mechanisms involved in cytoplasmic irradiation. PMID:19346686

  4. [Putting decriminalization of abortion to a refendum].

    1997-09-01

    Surveys conducted in Mexico by GIRE in 1992, 1994, and 1995 reveal that over 80% of the national population believes only a woman or a woman and her partner should make abortion decisions. Neither the government, the Church, nor physicians should intervene. Public opinion and the documented social and public health consequences of illegal abortion demonstrate the obsolescence of laws penalizing abortion. Mexico does not have a direct means of converting the opinions of the population into votes and laws. In place of referendums, committees of specialists have been convened; they are limited in number and ability to represent diverse groups, and oriented above all to the losses and gains of political and parliamentary disputes. The electoral reform of 1995-96 was a good example of the question under debate getting lost in partisan maneuvering. The Federal District and four states have initiated development of the referendum process, but the procedures have been too cumbersome and the results disappointing. In the current day, opinions are often formed not by following a rational process, but by bombardment with advertising appealing to irrational emotions. The democratic effects of referendum should be furthered by guaranteeing fair and exhaustive exposure of all points of view before the vote is held. GIRE recommends that a referendum on decriminalization of abortion should be preceded by a period of at least two years for public debate and reflection, and that the Federal Electoral Institute should organize the debate and the referendum.

  5. [Social hygiene aspects of abortion in Odessa].

    Zakharchenko, E M; Popov, V E

    1988-02-01

    The birth rate is a major concern in contemporary society today. Socialist countries having the material wherewithal and cultural wealth to maintain their populations have a genuine interest in population growth and maternity is therefore encouraged. The decision to have children lies with each individual family and does not involve society directly, except for the significant number of women who regulate their family size by having an abortion. In connection with the severity of such an intervention, a study of social and hygienic aspects of induced abortion was conducted in Odessa. The information was gathered anonymously among women who came to the gynecological department of a city hospital. 6.1% of the women were under age 20 and this figure may increase in the future. In the U.S. that figure already constitutes 1/3 of all abortions. 47.5% said they had had 3 previous abortions. 13.4% had no children, and 48.8% had 1 child. None of the women with no children thought of that as being the ideal. As reason for the abortion 31.7% gave irregular housing and living conditions, 12.2% unsatisfactory material well-being, 17.1% health reasons, 7.3% enough children already in the family, and 7.3% sickness of children and husband. In 24.4% of cases the husband was indifferent, and in 35.4% insisted on, and in 40.1% was against the woman having an abortion. 60% were thus probably poorly informed about the harmfulness of the operation. 39% of women did not use any contraception. Only 20% had received any information regarding contraceptives. Only 1/3 of obstetricians regularly instruct their patients about the use of contraceptives. Half of the nurses do not touch upon the subject due to lack of time and since instruction in birth control methods is not considered obligatory. Nevertheless it is important for women's health that during clinical examinations risk factors of abortion and the purposefulness of contraception are pointed out. PMID:3367727

  6. Review on abort trajectory for manned lunar landing mission

    2010-01-01

    Abort trajectory is a passage that ensures the astronauts to return safely to the earth when an emergency occurs. Firstly,the essential elements of mission abort are analyzed entirely based on summarizing the existing studies. Then,abort trajectory requirement and rational selection for different flight phases of typical manned lunar mission are discussed specifically. Considering a trade-off between the two primary constrains of an abort,the return time of flight and energy requirement,a general optimizing method for mission abort is proposed. Finally,some suggestions are given for China’s future manned lunar landing mission.

    1980-01-01

    Between August 1969, when the amendment to the Criminal Code went into effect, and December 1978 about 397 000 legal abortions were performed in hospitals with therapeutic abortion committees in Canada. During the 5-year period 1974-78 abortions in females under 20 years of age accounted for 30.9% of all the legal abortions performed in Canada on Canadian residents, and the abortion rate per 1000 women aged 15 to 19 years increased from 13.6 to 16.3. During 1974-77 the proportion of women in ...

  8. Visualising abortion: emotion discourse and fetal imagery in a contemporary abortion debate.

    Hopkins, Nick; Zeedyk, Suzanne; Raitt, Fiona

    2005-07-01

    This paper presents an analysis of a recent UK anti-abortion campaign in which the use of fetal imagery--especially images of fetal remains--was a prominent issue. A striking feature of the texts produced by the group behind the campaign was the emphasis given to the emotions of those viewing such imagery. Traditionally, social scientific analyses of mass communication have problematised references to emotion and viewed them as being of significance because of their power to subvert the rational appraisal of message content. However, we argue that emotion discourse may be analysed from a different perspective. As the categorisation of the fetus is a social choice and contested, it follows that all protagonists in the abortion debate (whether pro- or anti-abortion) are faced with the task of constructing the fetus as a particular entity rather than another, and that they must seek to portray their preferred categorisation as objective and driven by an 'out-there' reality. Following this logic, we show how the emotional experience of viewing fetal imagery was represented so as to ground an anti-abortion construction of the fetus as objective. We also show how the arguments of the (pro-abortion) opposition were construed as totally discrepant with such emotions and so were invalidated as deceitful distortions of reality. The wider significance of this analysis for social scientific analyses of the abortion debate is discussed. PMID:15893054

Detecting types and frequent psychological side effects of abortion among post abortion care seeking women in Tehran was the main objective of the present study. "n Method: 278 women of reproductive age (15-49 interviewed as study population. Response rate was 93/8. Data collected through a questionnaire with 2 parts meeting broad socio-economic characteristics of the respondents and health- related abortion consequences. Tehran hospitals were the site of study. "nResults: The results revealed that at least one-third of the respondents have experienced psychological side effects. Depression, worrying about not being able to conceive again and abnormal eating behaviors were reported as dominant psychological consequences of abortion among the respondents. Decreased self-esteem, nightmare, guilt, and regret with 43.7%, 39.5%, 37.5%, and 33.3% prevalence rates have been placed in the lower status, respectively. "nConclusion: Psychological consequences of abortion have considerably been neglected. Several barriers made findings limited. Different types of psychological side effects, however, experienced by the study population require more intensive attention because of chronic characteristic of psychological disorders, and women's health impact on family and population health.

  10. Herbal infusions used for induced abortion.

    Ciganda, Carmen; Laborde, Amalia

    2003-01-01

    Plants and herbs have been used to induce abortions but there is very little published information describing the commonly used ones. The purpose of this report is to describe the herbal products used to induce abortions, and to enhance awareness and understanding of their toxic effects. A descriptive retrospective survey was conducted on the calls received by the Montevideo Poison Centre between 1986 and 1999 concerning the ingestion of herbal infusions with abortive intent. A total of 86 cases involving 30 different plant species were identified. The species most frequently involved were ruda (Ruta chalepensis/graveolens), cola de quirquincho (Lycopodium saururus), parsley (Petroselinum hortense), and an over-the-counter herbal product named Carachipita. The components of Carachipita are pennyroyal (Mentha pulegium), yerba de la perdiz (Margiricarpus pinnatus), oregano (Origanum vulgare), and guaycuri (Statice brasiliensis). Abortion occurred in 23 cases after the ingestion of parsley, ruda, Carachipita, celery, Cedron, francisco alvarez, floripon, espina colorada. Out of the 23 cases, 15 involved the only the ingestion of plants, 4 cases used injected drugs (presumably hormones), and in 4 cases there was associated self-inflicted instrumental manipulation. Multiple organ system failure occurred in those patients who had ingested ruda (alone or in combination with parsley or fennel), Carachipita, arnica, or bardana. Deaths occurred in one case of Carachipita ingestion and in 4 cases of ruda ingestion (2 cases of ruda alone, 2 cases of ruda with parsley and fennel). Self-inflicted instrumental manipulations were found in 4 of the patients with multiple organ system failure and in one of those who died. The results of this report are not conclusive, but it appears that the ingestion of plants to induce abortion involves the risk of severe morbidity and mortality. PMID:12807304

  11. [Induced abortions in the Third Reich. Legal basis and provision].

    Link, G

    2000-01-01

    This article analyses, after introductory comments on the legal situation in the German Empire and the Weimar Republic, the legal basis for induced abortions during National Socialist rule in Germany. During this period the first legal definition for eugenically and medically indicated abortions was established. At the same time the prohibition of induced abortions outside these criteria was controlled more strictly and violations were punished more severely. This concerned abortions mainly for social reasons. The intention was to legalize abortion for those deemed "less worthy" while, at the same time, to minimise the number of abortions of those considered as "more valuable" to society. The main thrust of this policy was to increase the birth rate of "valuable" citizens. The second part of this paper focuses on eugenic and medical abortions at the University of Freiburg's Maternity Hospital. PMID:11050762

  12. Eliminating the phrase "elective abortion": why language matters.

    Janiak, Elizabeth; Goldberg, Alisa B

    2016-02-01

    The phrase "elective abortion" is often used to describe induced abortions performed for reasons other than a direct, immediate threat to maternal physical health. We argue that the term "elective abortion" is variably defined, misrepresents the complexity and multiplicity of indications for abortion and perpetuates stigma. In practice, restricting access to abortion at the legal, regulatory or institutional level based on subjective perceptions of patient need constrains health care providers' ability to act according to their best clinical judgments and limits patient access to care. The phrase "elective abortion" should be eliminated from scientific and medical discourse to prevent further damage to the public understanding of the variety of indications for which women require expeditious and equitable access to induced abortion.

    A male sterile germplasm of Chinese jujube(Ziziphus jujuba Mill.),named 'male sterile No.1'(JMS1),was firstly identified from a natural population through studies of pollen amount and vitality and its anatomy.Its microspores got massed and then disaggregated after the tetrad stage during pollen development.Then its anthers became empty,or only pollen vestiges remained in the yellow buds.The pollen became abortive after the tetrad stage.Hypertrophy and hyperplasia of tapetum at the tetrad stage were related to pollen abortion.In view of its moderate could be used as a worthwhile female parent in the cross breeding of Chinese jujube.

  15. Detection of cytoplasmic glycosylation associated with hydroxyproline.

    West, Christopher M; van der Wel, Hanke; Blader, Ira J

    2006-01-01

    A special class of glycosylation occurs on a proline residue of the cytoplasmic/nuclear protein Skp1 in the social amoeba Dictyostelium. For this glycosylation to occur, the proline must first be hydroxylated by the action of a soluble prolyl 4-hydroxylase acting on the protein. Cytoplasmic prolyl 4-hydroxylases are dioxygen-dependent enzymes that have low affinity for their O2 substrate and, therefore, have been implicated in O2-sensing in Dictyostelium, as well as in vertebrates and invertebrates. The sugar-hydroxyproline linkage has low abundance, is resistant to alkali cleavage and known glycosidases, and does not bind known lectins. However, initial screens for this modification can be made by assessing changes in electrophoretic mobility of candidate proteins after treatment of cells with prolyl hydroxylase inhibitors, and/or by metabolic labeling with [3H]sugar precursors. In addition, cytoplasmic hydroxylation/glycosylation can be assessed by assaying for cytoplasmic glycosyltransferases. Here we describe these methods and examples of their use in analyzing Skp1 glycosylation in Dictyostelium and the apicomplexan Toxoplasma gondii, the causative agent of toxoplasmosis in humans.

  17. Physician provision of abortion before Roe v. Wade.

    Joffe, C

    1991-01-01

    With the possibility of the Supreme Court overturning the landmark Roe v. Wade (1973) case legalizing abortion, a review of abortion practices pre-Roe is instructive. Abortion became criminalized in the US around 1870, yet many abortions were performed. While estimates for the yearly number of pre-Roe illegal abortions roughly resemble today's number of legal abortions, the difference between legal and illegal abortion rests in the difference between the large number of women who died or were injured then, and the very few women who now die from illegal abortions. Along with the self-induced abortion, different categories of providers performed illegal abortions: physicians, nonphysicians, nurses, midwives, and lay people; all with varying skill, experience, and motives. While there were "butchers" and sexual exploiters, there were also competent, beloved physicians. There were the financially motivated physicians providing abortions full time, and the occasional providers acting with a sense of conscience, risking successful practices and jail. Within this "conscience" group of 44 interviewees gathered through personal networks, ads, etc., abortions were: performed outside of hospitals, reducing the risk of discovery, but creating greater medical risks; begun outside of a hospital with the intrusion into the uterus of an object, provoking a "spontaneous abortion" (miscarriage) needing completion by D and C (dilation and curettage) within a hospital, but only a limited number of such patients could be referred before arousing suspicion; and in a hospital under disguised circumstances, a very tricky undertaking with severe limitations, available only a few times before risking detection. Avoidance and lack of training by today's physicians and the well organized antiabortion groups will undoubtedly make illegal abortions even more difficult to engage in than the pre-Roe days.

  18. The primary structure of rat brain (cytoplasmic) dynein heavy chain, a cytoplasmic motor enzyme.

    Zhang, Z.; Tanaka, Y.; Nonaka, S; Aizawa, H.; Kawasaki, H; Nakata, T; Hirokawa, N

    1993-01-01

    Overlapping cDNA clones encoding the heavy chain of rat brain cytoplasmic dynein have been isolated. The isolated cDNA clones contain an open reading frame of 13,932 bp encoding 4644 aa (M(r), 532,213). The deduced protein sequence of the heavy chain of rat brain dynein shows significant similarity to sea urchin flagellar beta-dynein (27.0% identical) and to Dictyostelium cytoplasmic dynein (53.5% identical) throughout the entire sequence. The heavy chain of rat brain (cytoplasmic) dynein con...

  19. An integrated model for the nucleo-cytoplasmic transport of cytoplasmic poly(A)-binding proteins.

    Burgess, Hannah M; Gray, Nicola K

    2012-05-01

    Cytoplasmic poly(A)-binding proteins (PABPs) regulate mRNA stability and translation. Although predominantly localized in the cytoplasm, PABP proteins also cycle through the nucleus. Recent work has established that their steady-state localization can be altered by cellular stresses such as ultraviolet (UV) radiation, and infection by several viruses, resulting in nuclear accumulation of PABPs. Here, we present further evidence that their interaction with and release from mRNA and translation complexes are important in determining their sub-cellular distribution and propose an integrated model for regulated nucleo-cytoplasmic transport of PABPs.

  20. Biblical views on abortion: an Episcopal perspective.

    Wilson-kastner, P; Blair, B

    1985-01-01

    Much scholarly work has been done to determine the biblical and traditional attitudes about abortion. One must ask what was said and why, what was its context, and inquire about what was not said as well. This discussion identifies some of the conclusions reached in scholarly literature. The word "abortion" is not mentioned in the Bible, but much in the Bible speaks to the issue. The most obvious passage is from Exodus 21:22-25. This part of the Covenant Code legislates the case of a pregnant woman who becomes involved in a brawl between 2 men and has a miscarriage. A distinction is then made between the penalty that is to be exacted for the loss of the fetus and injury to the woman. For the fetus, a fine is paid as determined by the husband and the judges. However, if the woman is injured or dies, "lex talionis" is applied -- life for life, eye for eye, etc. The story has somewhat limited application to the current abortion debate since it deals with accidental and not willful pregnancy termination. Even so, the distinction made between the woman and the fetus is important. The woman is valued as a person under the convenant; the fetus is valued as property. Its status is certainly inferior to that of the woman. This passage gives no support to the parity argument that gives equal religious and moral worth to woman and fetus. The bibilical portrait of person does not begin with an explanation of conception but with a portrayal of the creation of Adam and Eve. Thus, the biblical portrait of a person is that of a complex, many-sided creature with the god-like ability and responsibility to make choices. The fetus does not meet those criteria. When considering the issue of abortion, the one who unquestionably fits this portrait of personhood is the pregnant woman. The abortion question focuses on the personhood of the woman, who in turn considers the potential personhood of the fetus in terms of the multiple dimensions of her own history and the future. In biblical

  1. Adolescent male reproductive responsibility.

    Fox, L S

    1983-01-01

    A sample of 100 adolescent males enrolled in 2 high schools in suburban New Jersey completed a 30 item questionnaire in 1980 to explore further the attitudes and intended behavior of white, middle-class adolescent males regarding their reproductive responsibility. Data were sought on attitudes toward sex, contraception, pregnancy, and fatherhood. Also questioned were preferences about contraceptive use as well as anticipated behavior in the event of a partner's pregnancy. The study also was designed to obtain information on responses the subjects anticipated from their paretns on preferred pregnancy outcome. All respondents were white. 94%, based on data on the subjects' fathers, were ranked middle class and higher according to Hollingshead's Two Factor Index of Social Position. Ages ranged from 15-19 with a mean age of 16. 88% were living in households with both parents. Only 4% agreed that there was nothing wrong with telling a girl that you love her (even if you do not) so that she will agree to have sexual relations. This contrasts markedly with 61% of Vadies and Hale's lower-class sample of adolescent males who felt that deception was acceptable to obtain sex. 59% of the study group agreed that contraceptive use "shows concern for the girl," but the percentage dropped slightly to 53% regarding attitude toward using "protection whenever possible." The subjects demonstrated a contrast between attitude and intended behavior with 67% indicating an intention to use contraception when participating in sex regularly. 62% thought that for most of their peers would have sex and count on luck. 54% assumed that the "girl will protect herself." Respondents were more often willing either to help the close girlfriend range an abortion (28%), to marry her (21%), or to help her seek an adoption (20%). They were less likely to do the same for a casual girlfriend except in the case of abortion. A double standard was significantly evident on the basis of several preferred types

    Full Text Available In this study, we are presenting the results of cytogenetic analysis and molecular cytogenetic analysis of the couple and their family, who were referred to our genetic diagnostic laboratory with two abortions in their reproductive history. We found a normal karyotype (46,XX in female, and balanced reciprocal translocation [46,XY,t(3;18(p25;p11.3] in the male. To determine the parental origin of translocation, we examined the individuals of the family, and we found that the translocation: [46,XY,t(3;18(p25;p11.3] is paternally inherited. We concluded that the abortions in the history of this carrier family might be due to the unbalanced distribution of translocation, during gamete formation, prenatal diagnosis recommended for their further pregnancies.

  4. Medical abortion: Modern method for termination of pregnancy

    2010-01-01

    Full Text Available Introduction. Modern methods of medically induced abortions are being used in many countries all over the world. These methods are safe and effective when used in an appropriate way. Drugs used for medical abortion. The most widely used regimens for drug induced abortions include antiprogestogen mifepriston followed by administration of a synthetic prostaglandin analogue - gemeprost vaginally or misoprostol orally or vaginally. When used for abortions up to 9 and 7 weeks of pregnancy, this method has efficacy up to 98%. The regimen between 9 and 12 completed weeks is still under investigation. Methods for medical abortion after 12 completed weeks since last menstrual period include several regimens and medications - combination of mifepriston and repeated doses of misoprostol, misoprostol or gemeprost alone, methotrexate, synthetic prostaglandin analogues, oxytocin and some others. Medical abortions at our Department of Obstetrics and Gynecology, Novi Sad, Clinical Center Vojvodine, Serbia. Medical abortions in the second trimester were introduced at our Department of Obstetrics and Gynecology Novi Sad, Serbia, in early 1980s using prostaglandin analogues. This method was improved in year 2000 introducing two dinoprostone gels intracervically/extraamnially instead of just one, for cervical preparation before intramuscular application of carboprost thrometamine, which led to significantly shorter abortion interval. During the years 2003/2004 we took part successfully in one of the multicentric WHO projects for investigating new regimens on early medical abortions with mifepriston and misoprostol. Conclusions. Modern methods of medical abortions are safe and effective for termination of unwanted pregnancies in the first and second trimester.

  5. Induced abortion among Brazilian female sex workers: a qualitative study

    2015-02-01

    Full Text Available Prostitutes are vulnerable to unplanned pregnancies and abortions. In Brazil, abortion is a crime and there is no data about unsafe abortions for this population. The study describes how prostitutes perform illegal abortions and the health consequences thereof. Semi-structured interviews with 39 prostitutes from three cities in Brazil with previous induced abortion experience were conducted. Sixty-six abortions, with between one and eight occurrences per woman, were recorded. The majority of the cases resulted from sexual activity with clients. The inconsistent use of condoms with regular clients and the consumption of alcohol during work were indicated as the main causes of unplanned pregnancies. The main method to perform abortion was the intravaginal and oral use of misoprostol, acquired in pharmacies or on the black market. Invasive measures were less frequently reported, however with more serious health complications. The fear of complaint to the police meant that most women do not inform the health team regarding induced abortion. The majority of prostitutes aborted with the use of illegally-acquired misoprostol, ending abortion in a public hospital with infection and hemorrhagic complications. The data indicate the need for a public policy focusing on the reproductive health of prostitutes.

  7. [On the question of the illegality of abortion].

    Salton, J A

    1985-08-01

    The illegality of abortion in Brazil is questioned more and more. It would seem obvious that the prohibition of abortion would result in a decrease in the number of abortions, but upon closer observation, the opposite is true. Abortion related legislation in Brazil is among the most severe in the world. Both the physician and the patient are equally punishable, but this did not stop Brazilian women from having 3.5 million abortions/year. Countries with less severe laws have a much lower abortion rate. There have been extreme physiological and social consequences in Brazil as a result of abortion's illegality. The woman is not only a criminal, she is also a sinner in the eyes of the Church. In most cases, especially in low-income areas, abortion can lead to complications and death. Although there are no statistical data on the number of deaths due to illegal abortion, they would no doubt be alarming. An unwanted, unterminated pregnancy can have disastrous effects upon the mother, the child, and their relationship. These negative effects have been well documented. Prohibition will keep abortion out of the mainstream of national debate and aggravate the situation. A person's sexuality cannot be suppressed and considered evil. In lower income levels, unwanted pregnancy should not be a punishment for being poor. The legalization movement will grow, as it has in developed nations. The members of the Brazilian Society for Scientific Progress must remain active in the debate, because they cannot ignore something of such national importance. PMID:12314816

  8. Ugandan opinion-leaders' knowledge and perceptions of unsafe abortion.

    Moore, Ann M; Kibombo, Richard; Cats-Baril, Deva

    2014-10-01

    While laws in Uganda surrounding abortion remain contradictory, a frequent interpretation of the law is that abortion is only allowed to save the woman's life. Nevertheless abortion occurs frequently under unsafe conditions at a rate of 54 abortions per 1000 women of reproductive age annually, taking a large toll on women's health. There are an estimated 148,500 women in Uganda who experience abortion complications annually. Understanding opinion leaders' knowledge and perceptions about unsafe abortion is critical to identifying ways to address this public health issue. We conducted in-depth, semi-structured interviews with 41 policy-makers, cultural leaders, local politicians and leaders within the health care sector in 2009-10 at the national as well as district (Bushenyi, Kamuli and Lira) level to explore their knowledge and perceptions of unsafe abortion and the potential for policy to address this issue. Only half of the sample knew the current law regulating abortion in Uganda. Respondents understood that the result of the current abortion restrictions included long-term health complications, unwanted children and maternal death. Perceived consequences of increasing access to safe abortion included improved health as well as overuse of abortion, marital conflict and less reliance on preventive behaviour. Opinion leaders expressed the most support for legalization of abortion in cases of rape when the perpetrator was unknown. Understanding opinion leaders' perspectives on this politically sensitive topic provides insight into the policy context of abortion laws, drivers behind maintaining the status quo, and ways to improve provision under the law: increase education among providers and opinion leaders.

  9. Efforts underway to impose harsh regulations on abortion providers.

    Sollom, T

    1996-09-01

    Legislators or regulators in Mississippi, South Carolina, and Missouri have imposed burdensome and unnecessary clinic requirements on abortion providers. In each case, the legislators or regulators designed the requirements to make abortions more difficult to obtain. Mississippi, a state with only two licensed abortion clinics, already had restrictive abortion laws. In August 1996, it implemented stringent regulations on private physicians who provide abortion services in their offices. Some requirements include purchasing specific equipment, widening hallways, and hiring more staff. Several physicians have filed a lawsuit to stop enforcement of the regulations because they make the provision of abortion services so cumbersome and expensive as to discourage physicians from offering abortions. Antiabortion groups testified before the legislature that the Department of Health had been negligent in monitoring private practices for compliance with Mississippi's many abortion laws, particularly counseling requirements. The Republican governor signed the legislation in March 1996. In July 1996, a federal judge prohibited the South Carolina Department of Health from enforcing a new regulation making physicians who perform as few as five abortions a month to meet strict specifications for their office (e.g., disclosure of patient records and medical agreements). The regulation was a response to a 1995 law targeting private physicians who perform abortions in their offices. The judge held that the substantial changes in terms of privacy and expense could bring an undue burden on women seeking abortions. The state denied that the regulation would close clinics or would increase costs so much as to make abortions inaccessible. In September 1996, the House did not override the Democratic governor's veto of a bill that would have required all facilities where abortions are done to be licensed and undergo annual inspections and that would have required all physicians to have

  10. ABORTED GAMETOPHYTE 1 is required for gametogenesis in Arabidopsis.

    2015-12-01

    In flowering plants, the male and female gametogenesis is a crucial step of sexual reproduction. Although many genes have been identified as being involved in the gametogenesis process, the genetic mechanisms underlying gametogenesis remains poorly understood. We reported here characterization of the gene, ABORTED GAMETOPHYTE 1 (AOG1) that is newly identified as essential for gametogenesis in Arabidopsis thaliana. AOG1 is expressed predominantly in reproductive tissues including the developing pollen grains and ovules. The AOG1 protein shares no significant amino acid sequence similarity with other documented proteins and is located mainly in nuclei of the cells. Mutation in AOG1 caused degeneration of pollen at the uninucleate microspore stage and severe defect in embryo sacs, leading to a significant reduction in male and female fertility. Furthermore, the molecular analyses showed that the aog1 mutant significantly affected the expression of several genes, which are required for gametogenesis. Our results suggest that AOG1 plays important roles in gametogenesis at the stage prior to pollen mitosis I (PMI) in Arabidopsis, possibly through collaboration with other genes. PMID:25693728

    Astete A, Carmen; Beca I, Juan Pablo; Lecaros U, Alberto

    2014-11-01

    Abortion and its diverse possible legal regulations is one of the major and toughest social controversies. This debate is even more problematic due to biases, prejudgments, different ideologies, beliefs, religious doctrines and political pressures. Chile has recently begun a new national discussion with an evident confusion, both in juridical and clinical terminology, which makes very difficult to achieve the necessary plural debate for a social and political consensus. The authors structured an academic collaborative project to create a glossary as a contribution for a discussion based on clearly defined notions about the different terms used in the abortion debate. Twenty-two concepts were selected and their definitions were reviewed and discussed by more than 50 different specialists. The final version of this glossary in Spanish language is presented.

    Pregnancy interruption before fetal viability limit is inherent to a multidisciplinary reflection, due to the conflicts involved. Portuguese laws have been altered along time in the way of women's health protection, allowing the needed information and support towards a free, informed and enlightened decision. Deontological determinants about health professionals towards abortion indicate the practice accordingly the law. Nevertheless, it is safeguarded their right to consciousness objection. Ethical discussion about abortion, in its different ways, includes the concern about the value of intrauterine human life, and also the respect for individual autonomy. Even though the debate about intrauterine human life moral status is viewed from different theories and points of view, it is concluded that different perspectives about this matter are acceptable, in an interpersonal diversity valorization point of view.

  13. Orion Launch Abort System (LAS) Propulsion on Pad Abort 1 (PA-1)

    Jones, Daniel S.

    2015-01-01

    This presentation provides a concise overview of the highly successful Orion Pad Abort 1 (PA-1) flight test, and the three rocket motors that contributed to this success. The primary purpose of the Orion PA-1 flight was to help certify the Orion Launch Abort System (LAS), which can be utilized in the unlikely event of an emergency on the launchpad or during mission vehicle ascent. The PA-1 test was the first fully integrated flight test of the Orion LAS, one of the primary systems within the Orion Multi-Purpose Crew Vehicle (MPCV). The Orion MPCV is part of the architecture within the Space Launch System (SLS), which is being designed to transport astronauts beyond low-Earth orbit for future exploration missions. Had the Orion PA-1 flight abort occurred during launch preparations for a real human spaceflight mission, the PA-1 LAS would have saved the lives of the crew. The PA-1 flight test was largely successful due to the three solid rocket motors of the LAS: the Attitude Control Motor (ACM); the Jettison Motor (JM); and the Abort Motor (AM). All three rocket motors successfully performed their required functions during the Orion PA-1 flight test, flown on May 6, 2010 at the White Sands Missile Range in New Mexico, culminating in a successful demonstration of an abort capability from the launchpad.

  14. Molecular analyses of nuclear-cytoplasmic interactions affecting plant growth and yield. Final technical report

    Newton, K.J.

    1998-11-01

    Mitochondria have a central role in the production of cellular energy. The biogenesis and functioning of mitochondria depends on the expression of both mitochondrial and nuclear genes. One approach to investigating the role of nuclear-mitochondrial cooperation in plant growth and development is to identify combinations of nuclear and mitochondrial genomes that result in altered but sublethal phenotypes. Plants that have certain maize nuclear genotypes in combination with cytoplasmic genomes from more distantly-related teosintes can exhibit incompatible phenotypes, such as reduced plant growth and yield and cytoplasmic male sterility, as well as altered mitochondrial gene expression. The characterization of these nuclear-cytoplasmic interactions was the focus of this grant. The authors were investigating the effects of two maize nuclear genes, RcmI and Mct, on mitochondrial function and gene expression. Plants with the teosinte cytoplasms and homozygous for the recessive rcm allele are small (miniature) and-slow-growing and the kernels are reduced in size. The authors mapped this locus to molecular markers on chromosome 7 and attempted to clone this locus by transposon tagging. The effects of the nuclear-cytoplasmic interaction on mitochondrial function and mitochondrial protein profiles were also studied.

  16. Therapeutic abortion and Chlamydia trachomatis infection.

    Qvigstad, E; Skaug, K; Jerve, F; Vik, I S; Ulstrup, J C

    1982-01-01

    Chlamydia trachomatis was isolated from the cervix of 30 of 218 (13.8%) women admitted for legal termination of pregnancy. During the first two weeks after the abortion seven of the 30 (23.3%) patients developed pelvic inflammatory disease. Four of these had serological evidence of recent active chlamydial infection. Thus, routine examination of patients for genital chlamydial infection before termination of pregnancy is recommended.

  17. Endogenous Candida endophthalmitis after induced abortion.

    Chen, S J; Chung, Y M; Liu, J H

    1998-06-01

    Reported, in this article, are the cases of two young women who developed endogenous Candida endophthalmitis after induced abortion. Both women experienced transient fever, chills, and abdominal pain after the abortion and were given antibiotics. The diagnosis of endophthalmitis was established on the basis of typical fundus appearance, positive vaginal culture, and (in one case) positive vitreous culture. In the first woman, who received vitrectomy and intravitreal amphotericin B injection, the affected eye had a best corrected visual acuity of 20/200. In the second woman, who was given systemic corticosteroid treatment before the correct diagnosis was reached, recurrent retinal detachment developed and the best corrected visual acuity was counting fingers. It appears that Candida organisms harbored in the genital tract are directly inoculated into the venous system during induced abortion. Once in the blood, if sufficient fungal load is present, Candida albicans tends to localize in the choroid and to spread toward the retina and vitreous cavity. The immunosuppressive effect of corticosteroids further increases the risk of endophthalmitis. PMID:9645729

  18. US poised to outlaw late abortion technique.

    Bozalis, D

    1995-11-18

    The House of Representatives passed a bill, by a two-thirds majority (288-139), prohibiting late (at 19-20 weeks gestation) abortion using intrauterine cranial decompression. The bill now awaits judgment from the Senate Judiciary Committee for hearings. If the bill becomes law, physicians performing the procedure could face up to two years in prison. Chris Smith, Republican cochairman of the House Pro-Life Caucus, who introduced the bill in the House, described the vote as historic. During his emotional speech, the procedure was described in order to desanitize a form of abortion that he called barbaric torture. Patricia Schroeder, Colorado House Representative, argued that the wording of the bill allowed the procedure only when it was the only possible way of saving the mother's life; the woman's health and future fertility were, in effect, set aside. There is no exception clause for when the woman's life or health is endangered. Schroeder fears women will be forced to choose more dangerous methods of abortion and believes more discussion is required regarding health risks and a more precise definition of when the procedure may be used. She is joined by the California Medical Association, the American Medical Women's Association, the American College of Obstetricians and Gynaecologists, and the American Medical Association.

    Retroviral capsid (CA) cores undergo uncoating during their retrograde transport (toward the nucleus), and/or after reaching the nuclear membrane. However, whether HIV-1 CA core uncoating is dependent upon its transport is not understood. There is some evidence that HIV-1 cores retrograde transport involves cytoplasmic dynein complexes translocating on microtubules. Here we investigate the role of dynein-dependent transport in HIV-1 uncoating. To interfere with dynein function, we depleted d...

  2. 25 years later, US abortion war still drags on.

    Rovner, J

    1998-01-31

    In the 25 years since the US Supreme Court's landmark Roe vs. Wade decision legalizing abortion, activists on both sides of the issue have drawn further apart as they have vied for the support of the majority of US voters who express ambivalence towards the law. These voters believe that abortion may be murder but that it must be legal. The Roe vs. Wade anniversary has sparked new legislative priorities on both sides. Abortion-rights activists will seek legislation that attempts to decrease the need for abortion by increasing funding for family planning services in the US and abroad, supporting funding for contraceptive research, and requiring health insurers to pay for contraceptives. Abortion opponents will continue to press for "partial birth" abortion bans and will support efforts to make it a federal crime for an adult to transport a minor across state lines to evade state parental notification or consent laws.

  3. U.S. tries to defuse abortion debate.

    Struck, D

    1994-09-01

    In an apparent attempt to defuse acrimony at the International Conference on Population and Development, underway in Cairo, the US delegation is softening its stance on abortion decriminalization. US Vice President Al Gore, the head of the delegation, has stated, "The United States does not seek to establish a new international right to abortion, and we do not believe that abortion should be encouraged as a method of family planning." The Vatican and Muslim fundamentalists remain concerned, however, that the Cairo gathering represents an opportunity for the US to impose its abortion rights agenda on other countries. The draft prepared for presentation to the conference makes no explicit mention of legal abortion. Rather, it advocates safe motherhood, complete reproductive health care, and fertility control-- phrases the Vatican insists mask an intent to promote the use of abortion for family planning.

  4. Measuring abortion-related mortality: challenges and opportunities.

    Gerdts, Caitlin; Tunçalp, Ozge; Johnston, Heidi; Ganatra, Bela

    2015-01-01

    Two recent efforts to quantify the causes of maternal deaths on a global scale generated divergent estimates of abortion-related mortality. Such discrepancies in estimates of abortion-related mortality present an important opportunity to explore unique challenges and opportunities associated with the generation and interpretation of abortion-related mortality estimates. While innovations in primary data collection and estimation methodologies are much needed, at the very least, studies that seek to measure maternal deaths due to abortion should endeavor to improve transparency, acknowledge limitations of data, and contextualize results. As we move towards sustainable development goals beyond 2015, the need for valid and reliable estimates of abortion-related mortality has never been more pressing. The post-MDG development agenda that aims to improve global health, reduce health inequities, and increase accountability, requires new and novel approaches be tested to improve measurement and estimation of abortion-related mortality, as well as incidence, safety and morbidity.

  5. How Danes evaluate moral claims related to abortion

    Uldall, Sigurd Wiingaard

    2015-01-01

    OBJECTIVE: To investigate how Danish citizens evaluate four moral claims related to abortion issues, regarding the moral status of the fetus, autonomy, harm and possible negative consequences of allowing abortion and to explore the association between moral beliefs and attitudes towards abortion......-two responded to at least one moral claim. Two hundred and fifty-eight responded to all four claims without using the option 'neither agree nor disagree' and were classified as 'morally engaged responders'. A majority of these had a pro-abortion moral. The general relationship between moral beliefs and...... attitudes towards abortion was morally sound. Being 'morally engaged' did not increase the likelihood of reaching moral judgement on whether requests for abortion should be permitted. Education, religion and parenthood were statistically associated with the investigated issues. DISCUSSION: The direction of...

  6. Diagnostic studies of abortion in Danish dairy herds

    Agerholm, J.S.; Willadsen, C. M.; Nielsen, Thomas Krogh; Giese, Steen Bjørck; Holm, Elisabeth; Jensen, L.; Agger, J. F.

    Diagnostic findings in 218 aborted bovine foetuses are reported. The materials were examined in a matched case-control study of 69 Danish dairy herds with a sudden increase in the number of abortions and a corresponding 69 control herds. Foetuses aborted during the subsequent 6-month period were...... examined to identify the cause of abortion if possible. A total of 186 specimens were submitted from case herds and 32 from control herds. A likely cause of abortion was diagnosed in 73 foetuses. The most common cause was bovine viral diarrhoea virus (BVDV: 13%) followed by Neospora caninum infection (10......%), mycosis (5%) and Bacillus licheniformis infection (4%). Foetal and/or placental lesions were found in a further 27 cases. Only BVDV infection and neosporosis were diagnosed in more than one foetus per herd and only protozoal associated abortions occurred significantly more frequently in the case, rather...

  7. Stewardship challenges abortion: A proposed means to mitigate abortion's social divisiveness.

    Tardiff, Robert G

    2015-08-01

    Since 1973 the legislated constitutional right to abortion has produced a political dichotomy (anti-abortion versus pro-abortion) within the United States, even while witnessing a gradual decline in the rate of abortions. A third paradigm, moral stewardship, is advanced as an effective means to ameliorate this social divisiveness. Incorporating the concept of stewardship into deliberations of pregnancy termination would require recognition, through fact-based education programs, of the life circumstances that prompt the consideration to terminate a pregnancy. Based on collective responsibility, policies, and programs are needed to foster social justice for parents and for the offspring brought to term, without creating excessive burdens on women faced with an unwanted pregnancy. Moral stewardship is perceived as humanitarian to family and community and advantageous to society overall. It also offers a serious opportunity to reshape our society from divisiveness to inclusiveness, and to guide science policy judgment that enhances and strengthens social justice. Lay summary: Differing opinions over the ethics of human abortion have been legion since Roe v. Wade (1973). The disputes between pro- and anti-abortion factions have segregated society with few improvements in social justice. This study offers an alternative approach, one capable of social assimilation and justice for unwanted offspring and pregnant mothers bearing them. It promotes moral stewardship toward the unborn whose humanity and personhood are recognized genetically and supported philosophically by long-standing ethical principles. Stewardship incorporates all people at all levels of society based on collective responsibility, supported by government policies, yet not restricting a mother's choices for the future of her unborn offspring.

    Full Text Available Background: Recurrent abortion is defined as three or moreconsecutive pregnancy losses. We aimed to determine the relationshipbetween male sperm parameters and hypo-osmoticswelling score and recurrent abortion. We also studiedwhether washing of spermatozoa and intrauterine inseminationin patients with recurrent miscarriage and low score hypoosmoticswelling test in male partners could improve the outcomeof pregnancy.Methods: Between February 2003 and September 2006 ingynecology clinics affiliated to Shiraz University of MedicalSciences, 176 women with a history of recurrent abortionand their male partners were selected as study group. And159 healthy and fertile couples without a history of recurrentabortion were selected as control group. The relationship betweenmale sperm parameters and hypo-osmotic swelling testand recurrent spontaneous abortion in their female partnerswas evaluated after intrauterine insemination for those withabnormal hypo-osmotic swelling test. Outcome of pregnancyin patients with recurrent abortion whose male partners hadlow score hypo-osmotic swelling test was evaluated afterintrauterine insemination.Results: Low scores of hypo-osmotic swelling test weremore frequently seen in the study group than the controls:116 (65% versus 24 (15%. The mean hypo-osmotic swellingscore was significantly lower in the study group(P< 0.001. The outcome of pregnancy improved after intrauterineinsemination in those with low score hypoosmoticswelling test. The pregnancy success rate in thetreated group (pregnant with intrauterine insemination was77.77% while in the untreated group (pregnant without intrauterineinsemination was 30.76% with a success rateratio of 2.04.Conclusion: There was a positive relationship between lowhypo-osmotic swelling test score in male partners and recurrentabortion in their wives. Intrauterine insemination improvedthe outcome of pregnancy in these couples.

    The debate about the introduction and form of abortion legislation in Ireland is rife with floodgate arguments, suggesting (either implicitly or expressly) that the introduction of abortion legislation within current constitutional boundaries would only be a starting point, following which so-called ‘abortion on demand’ would flow. The recent discussions at the Oireachtas Committee on Health and Children showed little prospect of a break from this pattern. At those hearings, a number of parli...

    2014-01-01

    Among issues related to reproductive health, none has more controversial connotations than abortion nor carries a heavier burden of stigmatization. Abortion, is a universal phenomenon and is defined as and has existed throughout recorded history, yet it continues to be a highly charged, controversial issue, raising extreme passions among lay people, as well as politicians, religious leaders, and health and rights advocates. Although abortion services in India were liberalized more than three ...

  15. Childhood adversities and subsequent risk of one or multiple abortions

    Steinberg, Julia R.; Tschann, Jeanne M

    2012-01-01

    Although many studies have found an association between childhood adversities and mental health disorders, few have examined whether childhood adversities are linked to having abortions. This research investigates the association between a range of childhood adversities and risk of abortion in part to identify which adversities should be considered when examining the association between abortion and subsequent mental health. Using the U.S. National Comorbidity Survey-Replication (NCS-R), we t...

  17. Why women seek abortion? a qualitative study on perspectives of rural women on abortion and contraception

    Fatima Shanthini Navis

    2015-08-01

    Conclusion: These findings highlight the need to improve rural women's knowledge of fertility and contraception. Media and service providers should use every possible opportunity to educate women regarding the legal status of abortion and to promote contraceptive usage by creating awareness regarding safety and free availability of various contraceptives thereby clearing misconceptions regarding contraception. There is a need to educate rural women that use of a regular contraceptive method is better than undergoing repeated abortions. [Int J Reprod Contracept Obstet Gynecol 2015; 4(4.000: 1153-1157

  18. The transmission of cytoplasmic genes in Aspergillus nidulans.

    Coenen, A

    1997-01-01

    IntroductionThis manuscript concerns the spread of selfish cytoplasmic genes in the fungus Aspergillus nidulans. A.nidulans is a common soil fungus that grows vegetatively by forming a network (mycelium) of hyphae and reproduces via sexual ascospores and asexual conidiospores. Cytoplasmic genes are genes that are located in the cell cytoplasm and not in the cell nucleus where most genes are situated. The cytoplasmic genes investigated in this research are the genomes of mitochondria and virus...

  19. The Composition and Organization of Cytoplasm in Prebiotic Cells

    Trevors, Jack T.

    2011-01-01

    This article discusses the hypothesized composition and organization of cytoplasm in prebiotic cells from a theoretical perspective and also based upon what is currently known about bacterial cytoplasm. It is unknown if the first prebiotic, microscopic scale, cytoplasm was initially contained within a primitive, continuous, semipermeable membrane, or was an uncontained gel substance, that later became enclosed by a continuous membrane. Another possibility is that the first cytoplasm in prebio...

  20. Single and repeated elective abortions in Japan: a psychosocial study.

    Kitamura, T; Toda, M A; Shima, S; Sugawara, M

    1998-09-01

    Despite its social, legal and medical importance, termination of pregnancy (TOP) (induced abortion) has rarely been the focus of psychosocial research. Of a total of 1329 women who consecutively attended the antenatal clinic of a general hospital in Japan, 635 were expecting their first baby. Of these 635 women, 103 (16.2%) had experienced TOP once previously (first aborters), while 47 (7.4%) had experienced TOP two or more times (repeated aborters). Discriminant function analysis was performed using psychosocial variables found to be significantly associated with either first abortion or repeated abortion in bivariate analyses. This revealed that both first and repeated aborters could be predicted by smoking habits and an unwanted current pregnancy while the repeated aborters appear to differ from first aborters in having a longer pre-marital dating period, non-arranged marriages, smoking habits, early maternal loss experience or a low level of maternal care during childhood. These findings suggest that both the frequency of abortion and its repetition have psychosocial origins. PMID:9844843

  1. The abortion-crime link: evidence from England and Wales

    L H Kahane; Paton, D; Simmons, R.

    2005-01-01

    We use panel data from 1983 to 1997 for the 42 police force areas in England and Wales to test the hypothesis that legalizing abortion contributes to lower crime rates. We provide an advance on previous work by focusing on the impact of possible endogeneity of effective abortion rates with respect to crime. Our use of U.K. data allows us to exploit regional differences in the provision of free abortions to identify abortion rates. When we use a similar model and estimation methodology, we are...

  2. Do Induced Abortions Affect the First Birth Probability?

    Hansen, Marie-Louise H; Stage, Louise; Knudsen, Lisbeth B.;

    Objective: The focus of this paper is to study, on a national basis, how the event of an induced abortion modifies the transition to first birth for Danish women aged 20-39 years in the period 1982-2001, taking into account also educational level, family situation, and urbanisation. Data and...... abortion is examined by cumulative first birth probabilities, derived from a life table analysis. Main findings and conclusion: Previous abortions increased the first birth probability, though this effect was almost entirely confined to single women. For cohabiting and married women, previous abortions had...

  3. [Decriminalization of abortion: a common purpose in Latin America].

    1993-12-01

    In the conviction that abortion is a fundamental right of women and that its illegal practice constitutes a serious threat to life, several Latin American women's groups have united to work for decriminalization. The groups have been attempting to increase public awareness of the consequences of illegal abortion. Official silence on the topic appears to deny the existence of a problem. Proposals in the different Latin American countries are adapted to their political and legal circumstances. In Argentina, a campaign has been underway for nearly two years to collect signatures for a petition for a law concerning contraception and abortion. The National Network for Women's Health and other groups have held regional and national workshops on the issue. In Bolivia, radio and television programs have been broadcast in Spanish and indigenous languages on the right to choose, reproductive health, and sex education. Abortion was debated in Brazil during the process of constitutional reform, but it remains illegal. Illegal abortion continues to be a reality and women's groups are lobbying for decriminalization. Abortion is considered a crime in Colombia's penal code. Attempts to legalize abortion have been rejected by the legislature without debate. The practice of abortion under the circumstances has become a lucrative business whose lack of regulation has resulted in a growing number of maternal deaths. Attempts are underway in Costa Rica to legalize abortion in cases of rape or incest. Studies show that illegal abortion is the third most important cause of maternal death. A bill to legalize abortion is under study in Chile's Parliament but has not been approved. Abortion is illegal but common in Ecuador. Efforts are underway in Mexico and Nicaragua to encourage debate on abortion. Peru's Health Commission was recently prevented from classifying abortion for any reason other than grave congenital anomaly as homicide. Abortion has been legal in Puerto Rico since 1974, but

  6. Are all abortions equal? Should there be exceptions to the criminalization of abortion for rape and incest?

    Cohen, I Glenn

    2015-01-01

    Politics, public discourse, and legislation restricting abortion has settled on a moderate orthodoxy: restrict abortion, but leave exceptions for pregnancies that result from rape and incest. I challenge that consensus and suggest it may be much harder to defend than those who support the compromise think. From both Pro-Life and Pro-Choice perspectives, there are good reasons to treat all abortions as equal. PMID:25846041

  8. Effects of Abortion Legalization in Nepal, 2001–2010

    2013-01-01

    Background Abortion was legalized in Nepal in 2002, following advocacy efforts highlighting high maternal mortality from unsafe abortion. We sought to assess whether legalization led to reductions in the most serious maternal health consequences of unsafe abortion. Methods We conducted retrospective medical chart review of all gynecological cases presenting at four large public referral hospitals in Nepal. For the years 2001–2010, all cases of spontaneous and induced abortion complications were identified, abstracted, and coded to classify cases of serious infection, injury, and systemic complications. We used segmented Poisson and ordinary logistic regression to test for trend and risks of serious complications for three time periods: before implementation (2001–2003), early implementation (2004–2006), and later implementation (2007–2010). Results 23,493 cases of abortion complications were identified. A significant downward trend in the proportion of serious infection, injury, and systemic complications was observed for the later implementation period, along with a decline in the risk of serious complications (OR 0.7, 95% CI 0.64, 0.85). Reductions in sepsis occurred sooner, during early implementation (OR 0.6, 95% CI 0.47, 0.75). Conclusion Over the study period, health care use and the population of reproductive aged women increased. Total fertility also declined by nearly half, despite relatively low contraceptive prevalence. Greater numbers of women likely obtained abortions and sought hospital care for complications following legalization, yet we observed a significant decline in the rate of serious abortion morbidity. The liberalization of abortion policy in Nepal has benefited women’s health, and likely contributes to falling maternal mortality in the country. The steepest decline was observed after expansion of the safe abortion program to include midlevel providers, second trimester training, and medication abortion, highlighting the importance

  9. [Prevention of habitual abortion by buffycoat transfusions].

    Neumeyer, H; Kuhn, W; Götze, O; Hinney, B

    1985-01-01

    From an immunological point of view the product of pregnancy may be regarded as a haplo-different allotransplant. A system possibly closely linked to the HLA-region is postulated to lead to the immunological recognition of the fetus by the mother and, paradoxically, to a take of the "transplant". The postulated system apparently codes for antigens present on both trophoblast and adult lymphocytes (TLX = trophoblast-lymphocyte-crossreacting). The prevention of rejection is thought to be effected by blocking factors (BF) present in the serum or plasma of the mother. There may be different kinds of BF: a specific BF (detectable only in an autologous assay system), appearing late in pregnancy, which inhibits several lymphocyte-dependent reactions (e.g. production of MIF, MLC). This BF has been identified as an IgG-class antibody. a nonspecific BF, appearing early in pregnancy which inhibits the MLC in vitro. c) may be a third BF, also specific, which is found only in plasma but not in serum. All described BF-activities were absent in women with habitual abortions. HLA-identity or partial identity could imply TLX-identity. The consequence of such an identity could be: non-detection of the trophoblast by the immune system of the mother, no production of BF, abortion. However several investigators could not find any HLA-identity of the partners with habitual abortions. A protective effect on the fetus has been seen when pregnant women were immunised with adult leukocytes, using either buffycoats from various HLA-different but bloodgroup-compatible donors or isolated leukocytes from the spouse.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:4072314

  10. Decision making by single women seeking abortion.

    Quinn, M

    1980-01-01

    30 single women attending the Auckland Medical Aid Center (AMAC) for an abortion during a 3-week period in May 1977 were interviewed about the factors leading up to the pregnancy, the impact of the pregnancy on their relationships with relevant others, and the process of obtaining an abortion. The prospective subjects were divided into 2 age groups, 16-20 and 21-25 years and 2 residence groups, Auckland city area or beyond this area. The proportion of the sample selected from each category was intended to approximate proportions as reported for all AMAC clientele. Of the 30 women interviewed, half were aged less than 20 years and half were more than 20. 24 of the women were European and the remainder Polynesian. 3 women had previously been married, in 2 cases resulting in children. 3 women had given birth; 2 of these women were solo parents while 1 woman had had her child adopted. All those who had either married or given birth were in the 21-25 year age group. In 20 cases the women had decided on abortion either before pregnancy even occurred or as soon as it was confirmed. This along with the fact that only 2 women in this sample actually made the decision to seek an abortion after arriving at the clinic suggests that counseling directed at helping women decide the future of the pregnancy after arrival at the hospital is largely superfluous. Other major problems of the women which caused considerable stress included obtaining a doctor's referral to AMAC, the physical difficulties in getting to AMAC, changes the pregnancy precipitated in relationships between women and those they confided in. 2/3 of the younger group made little or no use of contraception. None gave ignorance as a reason for nonuse. Women in the older age group tended to use more sophisticated techniques, such as oral contraception (OC), IUD, or diaphragm; the younger women relied on condoms or used nothing at all. In addition to the 7 women who had never used contraception, a further 12 women

    Full Text Available Abstract Background We evaluated cytogenetic results occurring with first trimester pregnancy loss, and assessed the type and frequency of chromosomal abnormalities after assisted reproductive treatment (ART and compared them with a control group. We also compared the rate of chromosomal abnormalities according to infertility causes in ICSI group. Methods A retrospective cohort analysis was made of all patients who were referred to the Genetics Laboratory of Fertility Center of CHA Gangnam Medical Center from 2005 to 2009 because of clinical abortion with a subsequent dilation and evacuation (D&E performed, and patients were grouped by type of conception as follows: conventional IVF (in vitro fertilization (n = 114, ICSI (intracytoplasmic sperm injection (n = 140, and control (natural conception or intrauterine insemination [IUI] (n = 128. Statistical analysis was performed using SPSS software. Results A total 406 specimens were referred to laboratory, ten abortuses were excluded, and in 14 cases, we did not get any spontaneous metaphase, chromosomal constitutions of 382 specimens were successfully obtained with conventional cytogenetic methods. Overall, 52.62% of the miscarriages were found to be cytogenetically abnormal among all patients, the frequency was 48.4% in the control group, 54.3% of miscarriages after ICSI and 55.3% after conventional IVF (p = 0.503. The most prevalent abnormalities were autosomal trisomy, however, nine (11.69% sex chromosome aneuploidy were noted in the ICSI group vs. four (6.45% and two (3.23% cases in the conventional IVF group and control group. We compared chromosomal abnormalities of miscarriages after ICSI according to infertility factor. 55.71% underwent ICSI due to male factors, 44.29% due to non-male factors. ICSI group having male factors showed significantly higher risk of chromosomal abnormalities than ICSI group having non-male factors (65.8% vs. 34.2%, p = 0.009, odds ratio = 1.529, 95% CI = 1

  12. [Abortion: a public health or a family planning problem].

    Aguayo Hernandez, J R

    1991-01-01

    This work discusses various views of abortion and presents data on the legal aspects and incidence of abortion in Mexico as a contribution to a more productive dialogue on the problems of abortion. It is very difficult to deter women who have decided to seek an abortion, regardless of whether the procedure is legal or even safe. In the state of Sinaloa, Mexico, an abortion has not been punishable since 1939 if it caused by "imprudence", if the woman is a victim of rape, or if the woman's life is endangered by pregnancy. The penal codes of most Mexican states and the Federal District contain similar provisions. In October 1990, the state of Chiapas decriminalized abortion for most indications in the 1st 90 days of pregnancy on the basis that the fertility and growth rates were too high, many children were in situations of extreme poverty, and the widespread practice of illegal abortion led to high rates of maternal morbidity and mortality. The decree legalizing abortion in Chiapas was suspended in early 1991 by the Congress of Chiapas and is currently under further study by the National Commission on Human Rights. UNICEF estimates that in 1990, some 100,000 illegal abortions occurred daily in the world. 150,000-200,000 women may die each year as a result of illegal abortions. Today some 300 million couples throughout the world do not want more children but lack access to family planning. UNICEF estimates that the world rate of population growth would decline by 30% if all couples not desiring children practiced effective contraception. A large number of illegal abortions are believed to occur annually in Mexico. Abortions in Mexico are most common among married women of lower or lower middle class who already have children and who wish to avoid the economic hardships of a new baby. Perhaps because of their illegality, abortions represent a significant expense for a household. Unsafe abortions may cause serious health and fertility problems for women. The Mexican

  13. Wolbachia age-sex-specific density in Aedes albopictus: a host evolutionary response to cytoplasmic incompatibility?

    Pablo Tortosa

    Full Text Available BACKGROUND: Wolbachia bacteria have invaded many arthropod species by inducing Cytoplasmic Incompatibility (CI. These symbionts represent fascinating objects of study for evolutionary biologists, but also powerful potential biocontrol agents. Here, we assess the density dynamics of Wolbachia infections in males and females of the mosquito Aedes albopitcus, an important vector of human pathogens, and interpret the results within an evolutionary framework. METHODOLOGY/PRINCIPAL FINDINGS: Wolbachia densities were measured in natural populations and in age controlled mosquitoes using quantitative PCR. We show that the density dynamics of the wAlbA Wolbachia strain infecting Aedes albopictus drastically differ between males and females, with a very rapid decay of infection in males only. CONCLUSIONS/SIGNIFICANCE: Theory predicts that Wolbachia and its hosts should cooperate to improve the transmission of infection to offspring, because only infected eggs are protected from the effects of CI. However, incompatible matings effectively lower the fertility of infected males, so that selection acting on the host genome should tend to reduce the expression of CI in males, for example, by reducing infection density in males before sexual maturation. The rapid decay of one Wolbachia infection in Aedes albopictus males, but not in females, is consistent with this prediction. We suggest that the commonly observed reduction in CI intensity with male age reflects a similar evolutionary process. Our results also highlight the importance of monitoring infection density dynamics in both males and females to assess the efficiency of Wolbachia-based control strategies.

  15. Demographic and clinical profile of patients with complicated unsafe abortion

    To describe the demographic and clinical profile of patients admitted as a result of complicated unsafe abortion. The study was carried out in the Department of Obstetrics and Gynaecology, Jinnah Hospital, Lahore from August 2001 to July 2002. Patients admitted with complicated unsafe abortion were evaluated regarding age, parity, marital and educational status, indication for abortion, method used, qualification of abortion providers, contraceptive usage, complications and death rate in abortion seekers. Descriptive statistics was used for describing variables. Fiftynine patients were admitted with complicated unsafe abortion. The mean age was 29 years, 95% were married and multiparous, 40% had secondary and higher education, 85% approached unqualified abortion providers who used instrumentation in more than 40% of cases for termination of pregnancy resulting in visceral trauma. More than 50% were using contraception and 5% died due to postabortion complications. Unsafe abortion is a major health problem. The associated morbidity is much higher than mortality. This study focus on the need of postabortion care and easy accessibility to contraception to improve quality of health. (author)

  16. International comparison of regulations on abortion after radiation exposure

    Possible factors to consider when assessing the necessity of an abortion are: 1) Exposure in the highly sensitive phase (e.g. organogenesis); 2) after intake of radioactive substances, accumulation of this radioactive substance in critical organs; 3) doses higher than the dose limit of 1 rem; 4) the wish of the pregnant woman to have an abortion.

  18. The American abortion debate: culture war or normal discourse?

    Dillon, M

    1995-01-01

    This paper investigates whether James Hunter's culture war thesis is an apt characterization of the American abortion debate. The author focuses on three arguments central to Hunter's analysis: 1) that the abortion debate involves two paradigmatically opposed world views; 2) that debate about abortion, since it involves moral discourse, is structurally different than other political debates; and 3) that the new alignments in abortion politics are culturally significant. Examining existing research in each of these three domains, the author finds that the debate over abortion is more complex than suggested by Hunter. World views of pro-life and pro-choice activists, for example, share a commitment to some overlapping values; the argumentative structure of abortion discourse has a pattern rather similar to that of political debate more generally, and new alignments on abortion, such as that between the Catholic Church and the Southern Baptist Convention, do not displace historically embedded differences in symbolic resources and cultural orientation. As suggested by the author, it may be more helpful, therefore, to think of the abortion debate as an ongoing public conversation about America's cultural tradition and how it should be variously expressed in contemporary laws and practices.

  5. Medicine and abortion law: complicating the reforming profession.

    McGuinness, Sheelagh; Thomson, Michael

    2015-01-01

    The complicated intra-professional rivalries that have contributed to the current contours of abortion law and service provision have been subject to limited academic engagement. In this article, we address this gap. We examine how the competing interests of different specialisms played out in abortion law reform from the early twentieth-century, through to the enactment of the Abortion Act 1967, and the formation of the structures of abortion provision in the early 1970s. We demonstrate how professional interests significantly shaped the landscape of abortion law in England, Scotland, and Wales. Our analysis addresses two distinct and yet related fields where professional interests were negotiated or asserted in the journey to law reform. Both debates align with earlier analysis that has linked abortion law reform with the market development of the medical profession. We argue that these two axes of debate, both dominated by professional interests, interacted to help shape law's treatment of abortion, and continue to influence the provision of abortion services today.

    Carter, J. F.; Bown, R. L.

    1975-01-01

    A Return-to-Launch-Site (RTLS) abort with three Space Shuttle Main Engines (SSME) operational was examined. The results are trajectories and main engine cutoff conditions that are approximately the same as for a two SSME case. Requiring the three SSME solution to match the two SSME abort eliminates additional crew training and is accomplished with negligible software impact.

  7. Commercial availability of misoprostol and induced abortion in Brazil.

    Costa, S H

    1998-12-01

    In Brazil, abortion is only permitted to save the woman's life or in cases of rape. The principal effect of legal restrictions is not to make induced abortion practice less prevalent but to force poor women to resort to abortions performed under unhygienic conditions or attempt self-induced abortion. Within this context, misoprostol, a synthetic analogue of prostaglandin E1, was introduced in the country in 1986. Purchased over the counter in pharmacies, misoprostol has became a popular abortifacient method among Brazilian women. By 1990, about 70% of women hospitalized with abortion-related diagnoses reported use of the drug. In 1991, the Ministry of Health restricted the sale of misoprostol, and in some states its use was totally banned. While the proportion of abortions induced with misoprostol has decreased, the drug continues to be sold on the black market at an inflated value. Research indicates that women have acquired more experience with the drug over time, resulting in lower doses and more effective administration. Several studies show that the rate and severity of complications are significantly less among women who used misoprostol compared with women who used invasive methods. Research also suggests that about half of the women have complete abortion with misoprostol, but seek medical care as soon as they have vaginal bleeding. The experience of Brazilian women with misoprostol is an example of how women when faced with unwanted pregnancy will resort to illegal abortion whatever the costs are to their health. PMID:10075223

  8. Making legal abortion available in Brazil: partnerships in practice.

    Villela, W V; Araújo, M J

    2000-11-01

    This article describes the participation of feminist groups who work in the area of women's reproductive health and rights in campaigns for the provision of legal abortion in public hospitals in Brazil. Brazilian criminal law permits therapeutic abortion in cases where pregnancy is the result of rape or poses a serious risk to the life of the woman. Today, as a result of the combined efforts of feminists, health professionals and policymakers, more than 20 hospitals in Brazil are officially permitted to perform therapeutic abortions within the existing law. A model programme has also been developed to train service providers to do legal abortions, where the agreement of a hospital board can be obtained. This training has also improved care for illegally obtained, incomplete abortions in those hospitals but not in hospitals where doctors have not been trained. Problems with lack of access and concerns about the lack of public acceptance of abortion remain. Women not only need the right to abortion but also more services and health professionals who are trained to perform abortions across the whole country. PMID:11424253

    2012-09-01

    Iran has had replacement fertility since 2000. Upholding a small family size has led some couples to terminate unwanted pregnancies. Abortion is, however, permitted only on medical grounds in Iran. Using data from the Iran Low Fertility Survey, this study assessed sociodemographic correlates of abortion among a random sample of 5526 ever-married women aged 15-54 years, and used in-depth interviews to explore reasons for and psychological consequences of abortion among 40 women who had experienced an unintended pregnancy. Although social and economic concerns were the main reasons cited for seeking abortion, women experienced anxiety and depression when seeking pregnancy termination and thereafter. Social stigmatization arose from a belief that abortion is sinful and that misfortune experienced thereafter is punishment. Inadequate knowledge and misunderstanding of relevant Sharia laws discouraged women from seeking care when they experienced complications. Iran's reproductive health policies should be revised to integrate pre- and postabortion counseling. PMID:22920623

  10. Self-management of medical abortion: a qualitative evidence synthesis.

    Wainwright, Megan; Colvin, Christopher J; Swartz, Alison; Leon, Natalie

    2016-05-01

    Medical abortion is a method of pregnancy termination that by its nature enables more active involvement of women in the process of managing, and sometimes even administering the medications for, their abortions. This qualitative evidence synthesis reviewed the global evidence on experiences with, preferences for, and concerns about greater self-management of medical abortion with lesser health professional involvement. We focused on qualitative research from multiple perspectives on women's experiences of self-management of first trimester medical abortion (administration of medical abortion. We highlight particular considerations when offering self-management options, and identify key areas for future research. Further qualitative research is needed to strengthen this important evidence base. PMID:27578349

  11. Acquired Immune Deficiency Syndrome, Risky Sexual Behavior and Abortion

    Marshall H. Medoff

    2012-01-01

    Full Text Available Problem statement: incidence of abortion in the United States has steadily declined since 1990. The question is why? Approach: This study, using multiple linear regression, examines whether women’s unprotected sexual activity is deterred by the risk of contracting AIDS as reflected in decreased abortion rates. Results: The empirical evidence consistently finds that the prevalence of AIDS reduces the risky (unprotected sexual activity of women of childbearing ages 15-44 as reflected in their abortion rates. The empirical results remain robust for the abortion rates of teens ages 15-17 and for teens ages 15-19. Conclusion: The empirical results suggest that the behavioral modification induced by the prevalence of AIDS accounted for 21% of the decrease in abortion rates over the time period 1992-2005.

  12. Stumbling on status: abortion, stem cells, and faulty reasoning.

    Lebacqz, Karen

    2012-02-01

    Common arguments from the abortion debate have set the stage for the debate on stem cell research. Unfortunately, those arguments demonstrate flawed reasoning-jumping to unfounded conclusions, using value laden language rather than careful argument, and ignoring morally relevant aspects of the situation. The influence of flawed abortion arguments on the stem cell debate results in failures of moral reasoning and in lack of attention to important morally relevant differences between abortion and human embryonic stem cells. Among those differences are whose interests are at stake and the difference between an embryo in and out of the womb. Stem cell research differs from abortion in morally relevant ways and should be freed from the abortion debate and its flawed reasoning. PMID:22209889

  13. Surrogate Motherhood and Abortion for Fetal Abnormality.

    Walker, Ruth; van Zyl, Liezl

    2015-10-01

    A diagnosis of fetal abnormality presents parents with a difficult - even tragic - moral dilemma. Where this diagnosis is made in the context of surrogate motherhood there is an added difficulty, namely that it is not obvious who should be involved in making decisions about abortion, for the person who would normally have the right to decide - the pregnant woman - does not intend to raise the child. This raises the question: To what extent, if at all, should the intended parents be involved in decision-making? In commercial surrogacy it is thought that as part of the contractual agreement the intended parents acquire the right to make this decision. By contrast, in altruistic surrogacy the pregnant woman retains the right to make these decisions, but the intended parents are free to decide not to adopt the child. We argue that both these strategies are morally unsound, and that the problems encountered serve to highlight more fundamental defects within the commercial and altruistic models, as well as in the legal and institutional frameworks that support them. We argue in favour of the professional model, which acknowledges the rights and responsibilities of both parties and provides a legal and institutional framework that supports good decision-making. In particular, the professional model acknowledges the surrogate's right to decide whether to undergo an abortion, and the intended parents' obligation to accept legal custody of the child. While not solving all the problems that arise in surrogacy, the model provides a framework that supports good decision-making. PMID:25688455

  14. Making legal abortion accessible in Brazil.

    Faúndes, Anibal; Leocádio, Elcylene; Andalaft, Jorge

    2002-05-01

    Abortion is legal in Brazil if it is the only means to save the woman's life or if the pregnancy is the result of rape. Although this has been the law for over 60 years, it has almost never been applied until recent years. In the past five years, the number of hospitals providing care to women victims of sexual violence has increased from 4 to 63, of which 40 are currently providing legal abortions. This paper describes a sensitization project and advocacy work carried out from within the obstetric and gynaecology establishment which has succeeded in motivating many key individuals and hospital staff to provide services for pregnancy termination in cases of rape. The dialogue between medical leaders and women's rights advocates and the emphasis on comprehensive care of women who have suffered sexual violence are key elements in the success of this initiative. The support of medical professionals, the organization and strength of the women's health and rights movement, the political support at federal, state and city government levels, including from the Federal Ministry of Health, and ongoing advocacy within the medical establishment have all been important elements in making the provision of services a reality.

  15. Characteristics of Induced Abortion in China in the 1990s

    Xiao-chun QIAO

    2007-01-01

    Objective To understand the characteristics of induced abortion in China in the 1990s,and to find out the influential factors.Methods The overall number of induced abortions, calculate cohort induced abortion frequency, explore the impact of a child's sex and the number of previous children on induced abortions were estimated by using the data from the "National Population and Reproductive Health Survey" conducted by the National Family Planning Commission in November 1997.Results Induced abortions in China had their own characteristics, which were far different from other countries. The main difference was led by the fact that the country was driven by an implemented family planning program and nationwide population policies. The key cause of induced abortions was due to an inconsistency with the requirements of the family planning policy. However, as a result of effective and prevalent contraception, the rates of induced abortions were not quite high in the 1990s,when compared with other countries. Even though, in the early 1990s, the government had reinforced the family planning program through administration and legislation,unlike during the early 1980s when the one-child policy was implemented, the induced abortion rate and the number of induce abortions did not increase as the fertility rate substantially decreased.Concltsion This finding implies that the fertility declines in the 1990s were not caused by the number of induced abortions. The transition of the fertility ideology of the people has played an important role in the fertility decline, as institutional reform and socioeconomic development are implemented.

  17. Induction, maintenance and utilization of male sterility in leek (Allium ampeloprasum L.).

    Silvertand, B.C.H.J.

    1996-01-01

    This thesis describes research work performed in leek in relation to efforts to obtain or exploit a male sterility system for hybrid leek breeding. Male sterile plants can be found in every leek cultivar. The male sterility trait can be explained by a nuclear monogenic inheritance or by a nucleo-cytoplasmic inheritance. The existence of a nucleo-cytoplasmic inheritance remains speculative unless the maintainer genotype will be identified. No source of CMS has been found, sofar, in leek or rel...

  18. Structural biology of cytoplasmic and axonemal dyneins.

    Ishikawa, Takashi

    2012-08-01

    Dyneins are microtubule-based, ATP-driven motor proteins with six tandemly linked AAA+ domains, a long N-terminal tail and a coiled-coil stalk. Cytoplasmic dyneins function as individual homodimers and are responsible for minus-end-oriented transport along microtubules. Axonemal dyneins of flagella/cilia are anchored in arrays to peripheral microtubule doublets by their N-terminal tails, and generate sliding motions of adjacent microtubule doublets toward the plus end. The coiled-coil stalk is responsible for communication between the AAA+ domains and the microtubule binding domain. A number of isoforms of axonemal dyneins are integrated to generate bending motion. In this article I will review recent structural studies and address the question as to how dyneins generate force and cause bending in flagella/cilia. PMID:22664481

  19. Model for bidirectional movement of cytoplasmic dynein

    Sumathy, S

    2014-01-01

    Cytoplasmic dynein exhibits a directional processive movement on microtubule filaments and is known to move in steps of varying length based on the number of ATP molecules bound to it and the load that it carries. It is experimentally observed that dynein takes occasional backward steps and the frequency of such backward steps increases as the load approaches the stall force. Using a stochastic process model, we investigate the bidirectional movement of single head of a dynein motor. The probability for backward step is implemented based on Crook's fluctuation theorem of non-equilibrium statistical mechanics. We find that the movement of dynein motor is characterized with negative velocity implying backward motion beyond stall force. We observe that the motor moves backward for super stall forces by hydrolyzing the ATP exactly the same way as it does while moving forward for sub stall forces.

  20. Inborn errors of cytoplasmic triglyceride metabolism.

    Wu, Jiang Wei; Yang, Hao; Wang, Shu Pei; Soni, Krishnakant G; Brunel-Guitton, Catherine; Mitchell, Grant A

    2015-01-01

    Triglyceride (TG) synthesis, storage, and degradation together constitute cytoplasmic TG metabolism (CTGM). CTGM is mostly studied in adipocytes, where starting from glycerol-3-phosphate and fatty acyl (FA)-coenzyme A (CoA), TGs are synthesized then stored in cytoplasmic lipid droplets. TG hydrolysis proceeds sequentially, producing FAs and glycerol. Several reactions of CTGM can be catalyzed by more than one enzyme, creating great potential for complex tissue-specific physiology. In adipose tissue, CTGM provides FA as a systemic energy source during fasting and is related to obesity. Inborn errors and mouse models have demonstrated the importance of CTGM for non-adipose tissues, including skeletal muscle, myocardium and liver, because steatosis and dysfunction can occur. We discuss known inborn errors of CTGM, including deficiencies of: AGPAT2 (a form of generalized lipodystrophy), LPIN1 (childhood rhabdomyolysis), LPIN2 (an inflammatory condition, Majeed syndrome, described elsewhere in this issue), DGAT1 (protein loosing enteropathy), perilipin 1 (partial lipodystrophy), CGI-58 (gene ABHD5, neutral lipid storage disease (NLSD) with ichthyosis and "Jordan's anomaly" of vacuolated polymorphonuclear leukocytes), adipose triglyceride lipase (ATGL, gene PNPLA2, NLSD with myopathy, cardiomyopathy and Jordan's anomaly), hormone-sensitive lipase (HSL, gene LIPE, hypertriglyceridemia, and insulin resistance). Two inborn errors of glycerol metabolism are known: glycerol kinase (GK, causing pseudohypertriglyceridemia) and glycerol-3-phosphate dehydrogenase (GPD1, childhood hepatic steatosis). Mouse models often resemble human phenotypes but may diverge markedly. Inborn errors have been described for less than one-third of CTGM enzymes, and new phenotypes may yet be identified.

  1. House vote on Hyde changes dynamic of Congressional abortion debate.

    1993-07-27

    US Congressional action is summarized for actions taken on abortion amendments and abortion funding amendments during the month of July 1993. The Hyde Amendment was passed in the House on July 1, 1993; by a margin of 255 to 178; the Senate version will be voted on in August. The amendment was a victory for anti-abortion supporters, because it limited coverage of abortions under Medicaid to cases involving only life endangerment, rape, or incest. Both sides of the abortion debate were energized by the vote. The national Campaign for Abortion and Reproductive Equity (CARE) was launched on July 13 through support from a coalition of 130 organizations and Representatives Maxine Waters, Cynthia McKinney, and Nita Lowey. CARE aims to restore federal funding of abortion services for poor women and others using federally funded health care. The Freedom of Choice Act (FOCA) leaves abortion funding and parental involvement to the discretion of individual states. FOCA was characterized by Senator Carol Moseley-Braun, who withdrew her sponsorship of the bill, as not meeting the needs of the "marginalized, disrespected, and ignored population." 4 other Democratic women senators followed suit and promised to very strongly oppose all efforts to restrict abortions through amendments to appropriations bills. Senate appropriations bills were also considered during July. On July 15 the Senate Veterans Affairs (VA) Committee defeated an amendment that would have barred the use of federal funds for abortion services at VA hospitals, except in cases of rape, incest, or the saving of maternal life. Senate Committee members John Rockefeller and Tom Daschle contributed to the bill's defeat. Federal employee health insurance plans will continue to ban the coverage of abortion services due to passage by the Subcommittee on Treasury, Postal Service, and General Government. An amendment introduced by Senator Bond to allow abortions in cases of rape, incest, or risk to maternal life was adopted

  2. The perspective of rural physicians providing abortion in Canada: qualitative findings of the BC Abortion Providers Survey (BCAPS.

    Jennifer Dressler

    Full Text Available BACKGROUND: An increasing proportion of Canadian induced abortions are performed in large urban areas. For unknown reasons the number of rural abortion providers in Canadian provinces, such as British Columbia (BC, has declined substantially. This study explored the experiences of BC rural and urban physicians providing abortion services. METHODS: The mixed methods BC Abortion Providers Survey employed self-administered questionnaires, distributed to all known current and some past BC abortion providers in 2011. The optional semi-structured interviews are the focus of this analysis. Interview questions probed the experiences, facilitators and challenges faced by abortion providers, and their future intentions. Interviews were transcribed and analyzed using cross-case and thematic analysis. RESULTS: Twenty interviews were completed and transcribed, representing 13/27 (48.1% rural abortion providers, and 7/19 (36.8% of urban providers in BC. Emerging themes differed between urban and rural providers. Most urban providers worked within clinics and reported a supportive environment. Rural physicians, all providing surgical abortions within hospitals, reported challenging barriers to provision including operating room scheduling, anesthetist and nursing logistical issues, high demand for services, professional isolation, and scarcity of replacement abortion providers. Many rural providers identified a need to "fly under the radar" in their small community. DISCUSSION: This first study of experiences among rural and urban abortion providers in Canada identifies addressable challenges faced by rural physicians. Rural providers expressed a need for increased support from hospital administration and policy. Further challenges identified include a desire for continuing professional education opportunities, and for available replacement providers.

  3. Constructing the meaning of ultrasound viewing in abortion care.

    Kimport, Katrina; Weitz, Tracy A

    2015-07-01

    As ultrasound scanning becomes increasingly routine in abortion care, scholars and activists have forwarded claims about how viewing the ultrasound image will affect pregnant women seeking abortion, speculating that it will dissuade them from abortion. These accounts, however, fail to appreciate how viewing is a social process. Little research has investigated how ultrasound workers navigate viewing in abortion care. We draw on interviews with twenty-six ultrasound workers in abortion care for their impressions and practices around ultrasound viewing. Respondents reported few experiences of viewing dissuading women from abortion, but did report that it had an emotional effect on patients that they believed was associated with gestational age. These impressions informed their practices, leading many to manage patient viewing based on the patient's gestational age. Other aspects of their accounts, however, undercut the assertion that the meaning of ultrasound images is associated with gestation and show the pervasiveness of cultural ideas associating developing foetal personhood with increasing gestational age. Findings demonstrate the social construction of ultrasound viewing, with implications in the ongoing contestation over abortion rights in the US. PMID:25688650

  4. Effectiveness of family planning policies: the abortion paradox.

    Nathalie Bajos

    Full Text Available The relation between levels of contraceptive use and the incidence of induced abortion remains a topic of heated debate. Many of the contradictions are likely due to the fact that abortion is the end point of a process that starts with sexual activity, contraceptive use (or non-use, followed by unwanted pregnancy, a decision to terminate, and access to abortion. Trends in abortion rates reflect changes in each step of this process, and opposing trends may cancel each other out. This paper aims to investigate the roles played by the dissemination of contraception and the evolving norms of motherhood on changes in abortion rates.Drawing data from six national probability surveys that explored contraception and pregnancy wantedness in France from 1978 through 2010, we used multivariate linear regression to explore the associations between trends in contraceptive rates and trends in (i abortion rates, (ii unwanted pregnancy rates, (iii and unwanted birth rates, and to determine which of these 3 associations was strongest.The association between contraceptive rates and abortion rates over time was weaker than that between contraception rates and unwanted pregnancy rates (p = 0.003. Similarly, the association between contraceptive rates and unwanted birth rates over time was weaker than that between contraceptive rates and unwanted pregnancy rates (p = 0.000.

  5. [Abortion among female students and employees of a Brazilian university].

    Hardy, E; Rebello, I; Faúndes, A

    1993-04-01

    In Brazil, the subject of induced abortion is controversial and considered by some to be a serious public health problem. On the other hand there are little data available as to its frequency and general characteristics. The difficulty encountered in obtaining reliable information is to be explained by the illegality of abortion that inhibits women from talking about their experience, and most studies are carried out in hospitals and thus succeed in identifying only those women who have complications. A study was carried out in 1990, involving all the female graduate students and employees of a Brazilian university. Data was obtained through a questionnaire that was returned by mail, anonymously. This paper presents some of the results relating to the frequency of miscarriage and abortion in this population. Significantly more students than employees were less than 25 years old (85% and 13.7% respectively); fewer students were married or in a common-law union (11% of students as against 56% of employees) and four times fewer students than employees had never been pregnant (15% and 65%). Nine percent of the students and 14% of the employees had had at least one abortion. When only sometime pregnant women were taken into consideration, over half the students (59%) and 20% of the employees had had an abortion. Differences between the two groups were maintained when considered by age, both for miscarriage and abortion. Students of less than 25 years of age presented the highest percentage of abortion.

  6. Legal abortion services in Brazil--a national study.

    Madeiro, Alberto Pereira; Diniz, Debora

    2016-02-01

    This article presents the results of a mixed methods study of 68 legal abortion services in Brazil. The services were analyzed in two stages. The first stage was a census, in which all the institutions were sent an electronic questionnaire about the organization of the legal abortion services. The second stage was conducted in a sample of 5 reference services, one for each region of the country. In this stage, a form was used to collect data about the women and the abortions in the medical records, and 82 interviews with health professionals were conducted. Thirty-seven of the services informed they performed legal abortions, and the services were inactive in 7 states. Police reports, forensic reports, and court orders were required by 14%, 8% and 8% of the services, respectively. Women who underwent abortions were predominantly aged 15-29, single and Catholic. Most abortions were performed until 14 weeks in the case of rape-related pregnancy, by means of manual vacuum aspiration. According to the health professionals, the main difficulties faced in the services are the low availability of physicians to perform abortions and the insufficient training of the staff. The data reveal a discrepancy between the legal provision and the reality of the services. The implementation of more services and the strengthening of the existing services available are necessary.

  7. THE OUTCOME OF PREGNANCY IN PATIENTS WITH THREATENED ABORTION

    Prathap

    2015-10-01

    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

    Campbell, Edward M.; Dodding, Mark P.; Yap, Melvyn W.; Wu, Xiaolu; Gallois-Montbrun, Sarah; Malim, Michael H.; Stoye, Jonathan P.; Hope, Thomas J.

    2007-01-01

    Tripartite motif (TRIM)5α has recently been identified as a host restriction factor that has the ability to block infection by certain retroviruses in a species-dependent manner. One interesting feature of this protein is that it is localized in distinct cytoplasmic clusters designated as cytoplasmic bodies. The potential role of these cytoplasmic bodies in TRIM5α function remains to be defined. By using fluorescent fusion proteins and live cell microscopy, we studied the localization and dyn...

  10. The clustered protocadherin endolysosomal trafficking motif mediates cytoplasmic association

    Shonubi, Adam; Roman, Chantelle; Phillips, Greg R.

    2015-01-01

    Background Clustered protocadherins (Pcdhs) are a large family of neural cadherin-like proteins encoded by individual exons located within three gene clusters. Each exon codes an extracellular, transmembrane, and proximal cytoplasmic domain. These “variable” regions may be spliced to a constant cytoplasmic moiety encoded at the end of a cluster. Pcdh extracellular domains mediate homophilic cell-cell binding but their cytoplasmic domains cause intracellular retention and may negatively regula...

  11. The individual level cost of pregnancy termination in Zambia: a comparison of safe and unsafe abortion.

    Leone, Tiziana; Coast, Ernestina; Parmar, Divya; Vwalika, Bellington

    2016-09-01

    Zambia has one of the most liberal abortion laws in sub-Saharan Africa. However, rates of unsafe abortion remain high with negative health and economic consequences. Little is known about the economic burden on women of abortion care-seeking in low income countries. The majority of studies focus on direct costs (e.g. hospital fees). This article estimates the individual-level economic burden of safe and unsafe abortion care-seeking in Zambia, incorporating all indirect and direct costs. It uses data collected in 2013 from a tertiary hospital in Lusaka, (n = 112) with women who had an abortion. Three treatment routes are identified: (1) safe abortion at the hospital, (2) unsafe clandestine medical abortion initiated elsewhere with post-abortion care at the hospital and (3) unsafe abortion initiated elsewhere with post-abortion care at the hospital. Based on these three typologies, we use descriptive analysis and linear regression to estimate the costs for women of seeking safe and unsafe abortion and to establish whether the burden of abortion care-seeking costs is equally distributed across the sample. Around 39% of women had an unsafe abortion, incurring substantial economic costs before seeking post-abortion care. Adolescents and poorer women are more likely to use unsafe abortion. Unsafe abortion requiring post-abortion care costs women 27% more than a safe abortion. When accounting for uncertainty this figure increases dramatically. For safe and unsafe abortions, unofficial provider payments represent a major cost to women.This study demonstrates that despite a liberal legislation, Zambia still needs better dissemination of the law to women and providers and resources to ensure abortion service access. The policy implications of this study include: the role of pharmacists and mid-level providers in the provision of medical abortion services; increased access to contraception, especially for adolescents; and elimination of demands for unofficial provider

    2011-01-01

    This analysis examines whether the legalization of abortion changed high school graduation rates among the children selected into birth. Unless women in all socio-economic circumstances sought abortions to the same extent, increased use of abortion must have changed the distribution of child development inputs. I find that higher abortion ratios…

    2016-01-01

    Abstract Objective To understand the current availability and practice of first-trimester medical abortion (MA) in Canada. Design Using public sources and professional networks, abortion facilities across Canada were identified for a cross-sectional survey on medical and surgical abortion. English and French surveys were distributed by surface or electronic mail between July and November 2013. Setting Canada. Participants A total of 94 abortion facilities were identified. Main outcome measures Descriptive statistics on MA practice and facility and provider characteristics, as well as comparisons of MA practice by facility and provider characteristics using χ2 and t tests. Results A total of 78 of 94 (83.0%) facilities responded. Medical abortion represented 3.8% of first-trimester abortions reported (2706 of 70 860) in 2012. Among the facilities offering MA, 45.0% performed fewer than 500 first-trimester abortions a year, while 35.0% performed more than 1000. More MAs were performed in private offices or ambulatory health centres than in hospitals. Sixty-two physicians from 28 of 78 facilities reported providing first-trimester MA; 87.1% also provided surgical abortion. More than three-quarters of MA physicians were female and 56.5% were family physicians. A preponderance (85.2%) of providers offered methotrexate with misoprostol. Nearly all physicians (90.3%) required patients to have an ultrasound before MA, and 72.6% assessed the completion of the abortion with ultrasonography. Most physicians (74.2%) offered MA through 49 days after the onset of the last menstrual period, and 21.0% offered MA through 50 to 56 days; 37.1% reported providing MA to patients who lived more than 2 hours away. Four physicians from 1 site provided MA via telemedicine. Conclusion In Canada, MA provision using methotrexate and misoprostol is consistent with best-practice guidelines, but MA is rare and its availability is unevenly distributed.

  14. Response to Wisniewski on Abortion, Round Two

    Walter E. Block

    2011-03-01

    Full Text Available The two main views on the abortion controversy are pro life and pro choice. In my many previous writings on this subject (Block, 1977, 1978, 2001, 2004, 2008, 2010A, 2010B, 2010C, forthcoming; Block and Whitehead, 2005 I have offered a third alternative, evictionism. Wisniewski (2010A has offered criticisms of this perspective. In Block (2010C I argued against Wisniewski (2010A, claiming that evictionism was the correct libertarian analysis of this vexing question. Wisniewski (2010B constituted a rejoinder to Block (2010C, insisting that evictionism constituted an incorrect analysis. The present paper is a response to Wisniewski (2010B, in which I again attempt to defend evictionism against his attacks on this doctrine.

  15. Septic abortion caused by Campylobacter jejuni bacteraemia.

    Skuhala, Tomislava; Škerk, Višnja; Markotić, Alemka; Bukovski, Suzana; Desnica, Boško

    2016-08-01

    A 20-year-old female patient, 14 weeks pregnant, was admitted to hospital with anamnestic and clinical features of acute pyelonephritis. Clinical signs of septic abortion developed and after obstetric examination the therapy was changed to ampicillin, gentamicin and clindamycin. Campylobacter jejuni was isolated from blood cultures. Pathohistological findings confirmed diagnosis of purulent chorioamnionitis. After 2 weeks of ciprofloxacin administration the patient fully recovered. Campylobacter jejuni was not isolated from stool culture and no signs of acute enteritis were registered during the illness. Invasive forms of Campylobacter disease without enteritis are not unusual in immunocompromised hosts but they are restricted to C. fetus rather than C. jejuni isolates. PMID:25872616

  16. Shuttle abort landing site emergency medical services

    Mckenas, David K.; Jennings, Richard T.

    1991-01-01

    NASA and DOD studies of medical-planning and logistical problems are reviewed as applicable to providing emergency medical care at remote transoceanic abort landing (TAL) sites. Two options are analyzed including a modified surgical response team and a combination physician/medical technician team. The two concepts are examined in terms of cost-effectiveness, specific types of medical support such as blood procurement, and search-and-rescue requirements. It is found that the physician/technician team is more economically efficient, and the description of the concept permits the development of an effective TAL-site astronaut medical-support system. A balance is struck between the competing problems of cost and medical capability by planning for on-scene medical stabilization and air evacuation to DOD tertiary medical centers.

  17. Response to Block on Abortion, Round Three

    Jakub Bożydar Wiśniewski

    2011-03-01

    Full Text Available Block (2011 has offered a second round of counterarguments to my criticisms (Wisniewski 2010a, 2010b of the claim that his theory of evictionism is compatible with libertarianism. In this paper I attempt to demonstrate that my critique still stands. In particular, I focus on analyzing the argumentative weight of such issues mentioned in Block’s latest response as, among others, the distinction between proper ex post punishment and proper ex ante defense, the question of whether my causal analyses of trespass imply a commitment to positive obligations, Rothbard’s distinction between contracts and premises, the supposed irrelevance of the principle of pacta sunt servanda in the context of abortion, and the extent to which custom can qualify the ambit of applicability of the non-aggression principle.

  18. Solution structure of the dimeric cytoplasmic domain of syndecan-4

    Shin, J; Lee, W; Lee, D;

    2001-01-01

    cytoplasmic domain is dependent on its oligomeric status, the conformation of the syndecan-4 cytoplasmic domain itself is important in the understanding of its biological roles. Gel filtration results show that the syndecan-4 cytoplasmic domain (4L) itself forms a dimer stabilized by ionic interactions...... is affected by the presence of C1 and C2 regions. Therefore, we propose that although the 4V region in the full cytoplasmic domain has a tendency for strong peptide--peptide interaction, it may not be enough to overcome the repulsion of the C1 regions of syndecan-4L....

  20. Sodium kinetics in hypertonic saline abortion

    The sodium kinetics of hypertonic saline abortions have been followed by measuring the radioactivity and the sodium concentrations in amniotic fluid, maternal plasma, urine, the foetus and placenta after intrauterine installation of 20% hypertonic saline labelled with 22Na in order to determine the reason for abortion of a dead foetus in 24 to 48 hours, and reasons for sodium reactions. There is dilution of the 300 ml of amniotic fluid to a maximum of 1.5 to 2.0 litres in an exponential fashion, by the influx of mainly maternal water, slowing after 8 hours. There is an exponential type of increase in plasma radioactivity, also slowing after 8 hours. However, equilibration is never reached, the specific activity of the amniotic fluid remaining 10 times that of the plasma, and the sodium concentration 3 times that of the plasma. The urine equilibrates with the plasma, and about 3% of the administered dose is lost in 22 hours. The largest foetus and placenta picked up the least radioactivity. Thus, a more mature foetus may be protected to some degree against the hypertonic saline action; this has been observed clinically. Hyperkaliaemia was found in all four subjects, and hypoglycaemia occurred sporadically. These were not accompanied by any symptoms. Factors associated with expulsion of the dead foetus are dehydration and decreased circulation associated with fibrinoid necrosis of the placenta, which may also account for cessation of equilibration between maternal plasma and amniotic fluid. Although no saline reactions occurred, the role of extrauterine deposition of hypertonic saline, as shown in one subject, might be considered. (author)

  1. The 'more-abortions' objection to fetal tissue transplantation.

    Gillam, L

    1998-06-01

    One common objection to fetal tissue transplantation (FTT) is that, if it were to become a standard form of treatment, it would encourage or entrench the practice of abortion. This claim is at least factually plausible, although it cannot be definitively established. However, even if true, it does not constitute a compelling ethical argument against FTT. The harm allegedly brought about by FTT, when assessed by widely accepted non-consequentialist criteria, has limited moral significance. Even if FTT would cause more abortions to be performed, and abortion is taken to be a serious moral wrong, this is not sufficient in itself to make FTT wrong. PMID:9831285

  3. Orion Launch Abort System Performance During Exploration Flight Test 1

    McCauley, Rachel; Davidson, John; Gonzalez, Guillo

    2015-01-01

    The Orion Launch Abort System Office is taking part in flight testing to enable certification that the system is capable of delivering the astronauts aboard the Orion Crew Module to a safe environment during both nominal and abort conditions. Orion is a NASA program, Exploration Flight Test 1 is managed and led by the Orion prime contractor, Lockheed Martin, and launched on a United Launch Alliance Delta IV Heavy rocket. Although the Launch Abort System Office has tested the critical systems to the Launch Abort System jettison event on the ground, the launch environment cannot be replicated completely on Earth. During Exploration Flight Test 1, the Launch Abort System was to verify the function of the jettison motor to separate the Launch Abort System from the crew module so it can continue on with the mission. Exploration Flight Test 1 was successfully flown on December 5, 2014 from Cape Canaveral Air Force Station's Space Launch Complex 37. This was the first flight test of the Launch Abort System preforming Orion nominal flight mission critical objectives. The abort motor and attitude control motors were inert for Exploration Flight Test 1, since the mission did not require abort capabilities. Exploration Flight Test 1 provides critical data that enable engineering to improve Orion's design and reduce risk for the astronauts it will protect as NASA continues to move forward on its human journey to Mars. The Exploration Flight Test 1 separation event occurred at six minutes and twenty seconds after liftoff. The separation of the Launch Abort System jettison occurs once Orion is safely through the most dynamic portion of the launch. This paper will present a brief overview of the objectives of the Launch Abort System during a nominal Orion flight. Secondly, the paper will present the performance of the Launch Abort System at it fulfilled those objectives. The lessons learned from Exploration Flight Test 1 and the other Flight Test Vehicles will certainly

    Q-fever is a zoonotic infection. Pregnant women constitute a specific risk group as the infection may cause spontaneous abortion, intrauterine death, growth retardation, oligohydramnios and premature birth. A 39 year-old veterinarian had a spontaneous abortion in pregnancy week seven. During the...... first weeks of her pregnancy, she handled birth by-products from cows with Q-fever. The Q-fever titres revealed that she was most likely infected in very early pregnancy. According to the literature, infection in the first trimester constitutes a specific risk of spontaneous abortion....

    2015-01-01

    Ireland has some of the most restrictive abortion laws in the world. Abortion has been criminalised since 1861, and the passage of the 8th Amendment in 1983 introduced ‘the right to life of the unborn’ into the Constitution. The effects of the 8th Amendment are felt on a daily basis by women leaving Ireland for abortion, by pregnant women receiving maternal care, by doctors caring for pregnant women, and by lawyers working for the health service. As predicted by the then-Attorney General Pete...

  7. Correlates of Social Work Students' Abortion Knowledge and Attitudes: Implications for Education and Research.

    Begun, Stephanie; Bird, Melissa; Ramseyer Winter, Virginia; Massey Combs, Katie; McKay, Kimberly

    2016-07-01

    Researchers have established that individuals' abortion knowledge is positively associated with their support of abortion rights. However, social workers' personal beliefs regarding abortion are under-researched, even though social workers are often employed in health promotion and education roles in which the topic of abortion is encountered. The current study examines the results of a nationwide survey of social work students (N = 504) and explores the relationship between social work students' abortion knowledge and abortion attitudes. Less abortion knowledge was significantly associated with antichoice attitude endorsement. Implications for social work research, training, and education are subsequently discussed. PMID:27092856

  8. [Abortion in Brazil: a household survey using the ballot box technique].

    Diniz, Debora; Medeiros, Marcelo

    2010-06-01

    This study presents the first results of the National Abortion Survey (PNA, Pesquisa Nacional de Aborto), a household random sample survey fielded in 2010 covering urban women in Brazil aged 18 to 39 years. The PNA combined two techniques, interviewer-administered questionnaires and self-administered ballot box questionnaires. The results of PNA show that at the end of their reproductive health one in five women has performed an abortion, with abortions being more frequent in the main reproductive ages, that is, from 18 to 29 years old. No relevant differentiation was observed in the practice of abortion among religious groups, but abortion was found to be more common among people with lower education. The use of medical drugs to induce abortion occurred in half of the abortions, and post-abortion hospitalization was observed among approximately half of the women who aborted. Such results lead to conclude that abortion is a priority in the Brazilian public health agenda. PMID:20640252

    Faúndes, Aníbal; Duarte, Graciana Alves; de Sousa, Maria Helena; Soares Camargo, Rodrigo Paupério; Pacagnella, Rodolfo Carvalho

    2013-11-01

    Unsafe abortions remain a major public health problem in countries with very restrictive abortion laws. In Brazil, parliamentarians - who have the power to change the law - are influenced by "public opinion", often obtained through surveys and opinion polls. This paper presents the findings from two studies. One was carried out in February-December 2010 among 1,660 public servants and the other in February-July 2011 with 874 medical students from three medical schools, both in São Paulo State, Brazil. Both groups of respondents were asked two sets of questions to obtain their opinion about abortion: 1) under which circumstances abortion should be permitted by law, and 2) whether or not women in general and women they knew who had had an abortion should be punished with prison, as Brazilian law mandates. The differences in their answers were enormous: the majority of respondents were against putting women who have had abortions in prison. Almost 60% of civil servants and 25% of medical students knew at least one woman who had had an illegal abortion; 85% of medical students and 83% of civil servants thought this person(s) should not be jailed. Brazilian parliamentarians who are currently reviewing a reform in the Penal Code need to have this information urgently. PMID:24315072

  10. Induced mutant for male-sterility of lentil

    Full text: Lentil has very small flowers which pose problems in emasculation for cross-breeding. To induce mutations, seeds of variety LL-78 were irradiated with gamma rays 5 to 20 krad. In M2 some male-sterile plants were observed. Male-sterile plants could easily be identified at the start of maturity. They remain green and continue flowering when other plants mature. Due to natural outcrossing a few seeds formed on these male-sterile plants. These were grown in M2 for progeny testing. Some M3 lines were having both normal seed set and male-sterile plants in the ratio of 3 normal : 1 male-sterile, whereas in other lines all the plants were male-sterile. The former are assumed to be genic male-sterile and the latter cytoplasmic male-sterile. When the putative cytoplasmic male-sterile plants were selfed, there was no seed setting. Cytoplasmic male-sterility has not yet been reported in lentil. its use could make cross-breeding easier. (author)

    2012-01-01

    The widespread reliance on abortion in the Soviet Union, occasionally even referred to as an “abortion culture”, has been documented in a number of studies. However, the notoriously high abortion rates are not the only reason why the Soviet case stands out in the global history of abortion. Having decriminalised abortion by decree in 1920, Soviet Russia became the first country in the world where the termination of pregnancy was discussed as a legalised phenomenon. Russian discussions on ...

  13. Evolution of Wolbachia cytoplasmic incompatibility types.

    Dobson, Stephen L

    2004-10-01

    The success of obligate endosymbiotic Wolbachia infections in insects is due in part to cytoplasmic incompatibility (CI), whereby Wolbachia bacteria manipulate host reproduction to promote their invasion and persistence within insect populations. The observed diversity of CI types raises the question of what the evolutionary pathways are by which a new CI type can evolve from an ancestral type. Prior evolutionary models assume that Wolbachia exists within a host individual as a clonal infection. While endosymbiotic theory predicts a general trend toward clonality, Wolbachia provides an exception in which there is selection to maintain diversity. Here, evolutionary trajectories are discussed that assume that a novel Wolbachia variant will co-exist with the original infection type within a host individual as a superinfection. Relative to prior models, this assumption relaxes requirements and allows additional pathways for the evolution of novel CI types. In addition to describing changes in the Wolbachia infection frequency associated with the hypothesized evolutionary events, the predicted impact of novel CI variants on the host population is also described. This impact, resulting from discordant evolutionary interests of symbiont and host, is discussed as a possible cause of Wolbachia loss from the host population or host population extinction. The latter is also discussed as the basis for an applied strategy for the suppression of insect pest populations. Model predictions are discussed relative to a recently published Wolbachia genome sequence and prior characterization of CI in naturally and artificially infected insects. PMID:15562682

  14. Cytoplasmic dynein promotes HIV-1 uncoating.

    Pawlica, Paulina; Berthoux, Lionel

    2014-11-01

    Retroviral capsid (CA) cores undergo uncoating during their retrograde transport (toward the nucleus), and/or after reaching the nuclear membrane. However, whether HIV-1 CA core uncoating is dependent upon its transport is not understood. There is some evidence that HIV-1 cores retrograde transport involves cytoplasmic dynein complexes translocating on microtubules. Here we investigate the role of dynein-dependent transport in HIV-1 uncoating. To interfere with dynein function, we depleted dynein heavy chain (DHC) using RNA interference, and we over-expressed p50/dynamitin. In immunofluorescence microscopy experiments, DHC depletion caused an accumulation of CA foci in HIV-1 infected cells. Using a biochemical assay to monitor HIV-1 CA core disassembly in infected cells, we observed an increase in amounts of intact (pelletable) CA cores upon DHC depletion or p50 over-expression. Results from these two complementary assays suggest that inhibiting dynein-mediated transport interferes with HIV-1 uncoating in infected cells, indicating the existence of a functional link between HIV-1 transport and uncoating.

  16. A physical perspective on cytoplasmic streaming (invited)

    Goldstein, Raymond E

    2015-01-01

    Organisms show a remarkable range of sizes, yet the dimensions of a single cell rarely exceed $100$ $\\mu$m. While the physical and biological origins of this constraint remain poorly understood, exceptions to this rule give valuable insights. A well-known counterexample is the aquatic plant $Chara$, whose cells can exceed $10$ cm in length and $1$ mm in diameter. Two spiraling bands of molecular motors at the cell periphery drive the cellular fluid up and down at speeds up to $100$ $\\mu$m/s, motion that has been hypothesized to mitigate the slowness of metabolite transport on these scales and to aid in homeostasis. This is the most organized instance of a broad class of continuous motions known as "cytoplasmic streaming", found in a wide range of eukaryotic organisms - algae, plants, amoebae, nematodes, and flies - often in unusually large cells. In this overview of the physics of this phenomenon, we examine the interplay between streaming, transport and cell size, and discuss the possible role of self-organi...

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

    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.

  18. Orion Pad Abort 1 GN and C Design and Development

    Medina, Edgar A.; Stachowiak, Susan J.

    2010-01-01

    The first flight test of the Orion Abort Flight Test project is scheduled to launch in Spring 2010. This flight test is known as Pad Abort 1 (PA-1) and it is intended to accomplish a series of flight test objectives, including demonstrating the capability of the Launch Abort System (LAS) to propel the Crew Module (CM) to a safe distance from a launch vehicle during a pad abort. The PA-1 Flight Test Article (FTA) is actively controlled by a guidance, navigation, and control (GN&C) system for much of its flight. The purpose of this paper is to describe the design, development, and analysis of the PA-1 GN&C system. A description of the technical solutions that were developed to meet the challenge of satisfying many competing requirements is presented. A historical perspective of how the Orion LAV compares to the Apollo Launch Escape Vehicle (LEV) design will also be included.

  19. Incidence of legal abortion in Sweden after the Chernobyl accident

    The number of legal abortions in Sweden increased around the time of the Chernobyl accident, particularly in the summer and autumn of 1986. Although there was no recording of reasons for legal abortions, one might have suspected this increase to be a result of fear and anxiety after the accident. However, seen over a longer time perspective, the increase in the number of abortions started before and continued far beyond the time of the accident. There was also a simultaneous and pronounced increase in the number of births during the years subsequent to the accident. Therefore, it seems unlikely that fear of the consequences of radioactive fall-out after the Chernobyl accident resulted in any substantial increase of the number of legal abortions in Sweden

  1. Integrated Flight Performance Analysis of a Launch Abort System Concept

    Tartabini, Paul V.

    2007-01-01

    This paper describes initial flight performance analyses conducted early in the Orion Project to support concept feasibility studies for the Crew Exploration Vehicle s Launch Abort System (LAS). Key performance requirements that significantly affect abort capability are presented. These requirements have implications on sizing the Abort Motor, tailoring its thrust profile to meet escape requirements for both launch pad and high drag/high dynamic pressure ascent aborts. Additional performance considerations are provided for the Attitude Control Motor, a key element of the Orion LAS design that eliminates the need for ballast and provides performance robustness over a passive control approach. Finally, performance of the LAS jettison function is discussed, along with implications on Jettison Motor sizing and the timing of the jettison event during a nominal mission. These studies provide an initial understanding of LAS performance that will continue to evolve as the Orion design is matured.

  2. Induced first-trimester abortion and risk of mental disorder

    Background Concern has been expressed about potential harm to women's mental health in association with having an induced abortion, but it remains unclear whether induced abortion is associated with an increased risk of subsequent psychiatric problems. Methods We conducted a population-based cohort...... study that involved linking information from the Danish Civil Registration system to the Danish Psychiatric Central Register and the Danish National Register of Patients. The information consisted of data for girls and women with no record of mental disorders during the 1995–2007 period who had a first......-trimester induced abortion or a first childbirth during that period. We estimated the rates of first-time psychiatric contact (an inpatient admission or outpatient visit) for any type of mental disorder within the 12 months after the abortion or childbirth as compared with the 9-month period preceding the event...

    2007-01-01

    Background Inhibition of the key costimulatory signals results in T cell anergy, indicating the alloantigen-specific immunologic unresponsiveness. In this study, the effect of blockage of costimulatory signal CD86 on murine abortion-prone model was studied.Methods Thirty CBA/J female mice cohabitated with DBA/2 male or BALB/c male mice were investigated. CBA/J ×DBA/2 matings were used as the abortion-prone model, and CBA/J × BALB/c matings were used as the normal pregnant model. The abortion-prone models were divided into experimental and control groups, and the normal pregnant models were set as a normal group (10 mice in each group). The mice in the experimental group were treated with anti-mouse CD86 monoclonal antibody (mAb) (100 μg) on day 4.5 of gestation, while the controls received irrelevant-isotype matched rat IgG2b. As for the normal group, nothing was given to the mice. The mice were killed on day 13.5 of gestation, embryo resorption rate and the expression of transforming growth factor β1 (TGF-β1), plasminogen activator inhibitor 1 (PAI-1), and matrix metalloproteinase 9 (MMP-9) were detected. Then the data were analyzed by Chi-square test and Fisher's exact test.Results The embryo resorption rate in the experimental (8.2%) and normal groups (7.7%) was significantly lower than that of the control (23.5%, P<0.05). No significant difference was detected between the experimental and normal groups (P>0.05). The positive expression rates of TGF-β1 and PAI-1 proteins in the experimental and normal groups were significantly higher than those in the control group (P<0.05). The positive expression rate of MMP-9 protein in the experimental and normal groups was significantly lower than that in the control group (P<0.05). No significant difference in the positive expression rates of the three proteins was detected between the experimental and normal groups (P>0.05).Conclusions Blockage of costimulatory signal CD86 at early pregnancy can treat

    Problem statement: incidence of abortion in the United States has steadily declined since 1990. The question is why? Approach: This study, using multiple linear regression, examines whether womens unprotected sexual activity is deterred by the risk of contracting AIDS as reflected in decreased abortion rates. Results: The empirical evidence consistently finds that the prevalence of AIDS reduces the risky (unprotected) sexual activity of women of childbearing ages 15-44 as reflected in their a...

  9. The abortion debate: can this chronic public illness be cured?

    Callahan, D

    1992-12-01

    Abortion has provided one of the most noxious, disturbing, and unending of all American moral and legal struggles. The issue forces us to think about the most difficult kind of ethical issues, e.g., the moral status of the fetus and the meaning of human "life" and "personhood." The win-at-all-costs attitude among the leading advocacy groups has created gross stereotypes. While most arguments heard today were also heard prior to the Roe vs. Wade decision, the tone has radically changed. Better organization has meant hotter rhetoric and a nastier public style. We need to move the abortion debate along; it is now as stagnate as it is nasty. We need creative discussion and realistic compromise. The pre-Roe arguments in favor of choice have changed. Then, the movement to legalize abortion rested on the following: 1) illegal abortions were killing and maiming women; 2) women should have a backup to ineffective contraception; 3) the number of unwanted pregnancies should be reduced; only wanted children should be born, as a matter of child welfare; 4) women should have the right to make the abortion decision; 5) everything possible should be done to change the economic and domestic circumstances forcing women into unwanted pregnancies. The argument benefited women, children, and society. The many abortion myths that have since taken prominence cloud an already difficult issue. The ongoing tension rests with the conflict between the moral and legal issues. Is it possible to combine legal freedom and seriousness about the moral questions? Only if we recognize the equality of both positions' moral traditions, accept public discussion, the need for compromise, the need to do everything possible to change the economic and social circumstance leading to the abortion choice, and the need for meaningful counseling of women considering abortion.

  10. Misperceptions about contraceptives keep abortion incidence high in Ghana.

    1994-01-01

    Only 13% of couples in Ghana practiced contraception in 1988. During the period of nursing following childbirth, it is traditional for the new mother to abstain from sexual intercourse. She is subject to considerable social scorn should she conceive too soon after a previous delivery. Conceiving in short order, nonetheless, women long resorted to clandestine, unsafe abortions during the postpartum interval. The government of Ghana legalized the practice of induced abortion in 1985 so that women could limit their fertility in safety with registered and certified medical practitioners. The author studied 900 women seeking an induced abortion or reporting complications resulting from induced abortion performed outside a hospital setting to see why, in spite of high knowledge of contraception, Ghanaian women resort to abortion instead of using contraception. Subjects were recruited from the KorleBu Teaching Hospital in Accra, the Tema General Hospital of Tema, the Nsawam Hospital of Nsawam, and two abortion clinics in Accra. 55% were married, 25% were teenagers, and 56% were residents of Accra, while the rest were from rural areas. Among those who were married, 45% were the third wives. Most of the women had some formal education and some degree of economic independence. 99% knew of at least one method of contraception, only 21% had ever used a modern method, 6% had used a condom, 4% had used withdrawal sometimes, and 3% had used the rhythm method. The women reported not using modern contraceptives mainly because of the belief that they cause harmful side-effects. For example, it was commonly thought that the oral contraceptive pill causes infertility and withdrawal causes stroke in men. Women also viewed contraceptives as messy, complicated, and/or difficult to use. 54% said they decided to abort their fetus because the pregnancy was out of wedlock; single parenthood is stigmatized in Ghana. 25% decided to abort to better space their children.

  11. The abortion-crime link: evidence from England and Wales

    Simmons, R.; L H Kahane; Paton, D.

    2008-01-01

    Using data from England and Wales, we test the hypothesis that legalizing abortion reduces crime. The timing of changes in crime rates in aggregate data is generally inconsistent with this hypothesis. Using panel data on recorded crime from 1983 to 2001, we are able to replicate the negative association between abortion rates and reported crime that J. J. Donohue and S. D. Levitt found for the United States. However, this association breaks down under the scrutiny of robustness checks and is ...

    2012-01-01

    The hypothesis that the legalisation of abortion contributed significantly to the reduction of crime in the United States in 1990s is one of the most prominent ideas from the recent “economics-made-fun” movement sparked by the book Freakonomics. This paper expands on the existing literature about the computational stability of abortion-crime regressions by testing the sensitivity of coefficients’ estimates to small amounts of data perturbation. In contrast to previous studies, we use a new da...

    江静; 傅曼芬; 王德芬

    2001-01-01

    Objective To examine the relationship between spontaneous abortion and chromosomal abnormalities. Methods Couples who had one or more consecutive spontaneous abortions and had normal genitals were enrolled for cytogenetic karyotype analysis. Results In the 61 couples, the detected incidence was 11.5%, with five Robertsonian translocations, one reciprocal translocation, and one pericentric inversion of chromosome 7. Conclusion Chromosomal abnormalities may play an important role in fetal wastage.

  15. Abortion in America: A Consumer-Behavior Perspective.

    Patterson, Maggie Jones; Hill, Ronald Paul; Maloy, Kate

    1995-01-01

    Abortion is the most frequently performed surgical procedure in this country, yet its provision to consumers remains one of the most contentious issues within our society. The purpose of this article is to broaden our understanding of this problem by examining abortion from a consumer-behavior perspective. The phenomenological study described in this article revealed that (1) a wide gap exists between the language of the public debate and that of private decision making, (2) the language of p...

  16. The Abortion Issue in the Development Agenda of Latin American

    Marta Lamas

    2008-01-01

    This article, which offers a regional overview of the feminist struggle for abortion rights in Latin America, begins by reminding the reader of the context, characterized by poverty and marginalization, in which the region's women become mothers, as well as the deadly consequences of illegal abortion. It subsequently outlines the political tension between some state governments and feminists, particularly the friction that results from interference by the Catholic church hierarchy. The articl...

  17. Human rights and the right to abortion in Latin America

    Alejandra Zúñiga-Fajuri

    2014-01-01

    The scope of this study is to question the fact that in some countries in Latin America (Chile, El Salvador, Nicaragua, Honduras and the Dominican Republic) abortion is still forbidden in all situations. Even after all the debate on this thorny issue, the theory of human rights is not often used in the defense of abortion. This is clearly related to the pervasive, albeit unspoken belief that, due to their condition, pregnant women inherently lose their full human rights and should surrender a...

  18. Balanced Chromosomal Rearrangement in Recurrent Spontaneous Abortions: A Case Report

    Zarifian, Ahmadreza; Farhoodi, Zeinab; Amel, Roya; Mirzaee, Salmeh; Hassanzadeh-Nazarabadi, Mohammad

    2012-01-01

    One of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. We report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. Chromosomal studies were performed on the basis of G-banding technique at high resolution and revealed 46, XX, t (16; 6) (p12; q26) and 46, XY, t (16; 6) (p12; q26) in both partners, which induced such pregnancy complications. Chromosomal ...

  19. Women's Awareness and Knowledge of Abortion Laws: A Systematic Review.

    Anisa R Assifi

    Full Text Available Incorrect knowledge of laws may affect how women enter the health system or seek services, and it likely contributes to the disconnect between official laws and practical applications of the laws that influence women's access to safe, legal abortion services.To provide a synthesis of evidence of women's awareness and knowledge of the legal status of abortion in their country, and the accuracy of women's knowledge on specific legal grounds and restrictions outlined in a country's abortion law.A systematic search was carried for articles published between 1980-2015. Quantitative, mixed-method data collection, and objectives related to women's awareness or knowledge of the abortion law was included. Full texts were assessed, and data extraction done by a single reviewer. Final inclusion for analysis was assessed by two reviewers. The results were synthesised into tables, using narrative synthesis.Of the original 3,126 articles, and 16 hand searched citations, 24 studies were included for analysis. Women's correct general awareness and knowledge of the legal status was less than 50% in nine studies. In six studies, knowledge of legalization/liberalisation ranged between 32.3%-68.2%. Correct knowledge of abortion on the grounds of rape ranged from 12.8%-98%, while in the case of incest, ranged from 9.8%-64.5%. Abortion on the grounds of fetal impairment and gestational limits, varied widely from 7%-94% and 0%-89.5% respectively.This systematic review synthesizes literature on women's awareness and knowledge of the abortion law in their own context. The findings show that correct general awareness and knowledge of the abortion law and legal grounds and restrictions amongst women was limited, even in countries where the laws were liberal. Thus, interventions to disseminate accurate information on the legal context are necessary.

  20. Abortion in Brazil: Contending Discourses and Women's Experiences

    Tussi, Fernanda P.

    2010-01-01

    It is a common practice for anthropologists to explore connections where scholars from different disciplines do not expect to search and find them. This is the theoretical and methodological orientation in which I was trained as an anthropologist and from which I approach the practice of abortion in Brazil in hope to reach an understanding of the constituent dimensions of this social fact. Before I move on the to discussion, I would like to provide some background on the practice of abortion ...

  1. Child-bearing after induced abortion: reassessment of risk.

    Seidman, D S; Ever-Hadani, P.; Slater, P E; Harlap, S; Stevenson, D K; Gale, R.

    1988-01-01

    We reviewed 1791 singleton pregnancies of women with a history of previous induced abortion and compared them with 14,857 pregnancies in mothers with no previous induced abortions. Therapeutic termination of pregnancy was associated with a statistically significant increase in the incidence of low birth weight infants and bleeding in the first trimester of pregnancy. When other variables were examined, no significant differences were found between the two groups, except for a significantly hi...

  2. Screening for genetic disorders: therapeutic abortion and IVF.

    Michael, M.; Buckle, S

    1990-01-01

    This paper examines a proposal to make use of IVF techniques to provide an alternative to therapeutic abortion of fetuses with genetic abnormalities. We begin by describing the proposed procedure, and then show that, considered in itself, it is morally on a par with therapeutic abortion. However, once the wider practical implications are brought into view, the proposed new procedure loses its initial appeal. The pros and cons are not sufficiently clear-cut entirely to rule out the IVF procedu...

  3. Long Non-coding RNAs in the Cytoplasm

    Farooq Rashid; Abdullah Shah; Ge Shan

    2016-01-01

    An enormous amount of long non-coding RNAs (lncRNAs) transcribed from eukaryotic genome are important regulators in different aspects of cellular events. Cytoplasm is the residence and the site of action for many lncRNAs. The cytoplasmic lncRNAs play indispensable roles with multiple molecular mechanisms in animal and human cells. In this review, we mainly talk about functions and the underlying mechanisms of lncRNAs in the cytoplasm. We highlight relatively well-studied examples of cytoplasmic lncRNAs for their roles in modulating mRNA stability, regulating mRNA translation, serving as competing endogenous RNAs, functioning as precursors of microRNAs, and mediating protein modifications. We also elaborate the perspectives of cytoplasmic lncRNA studies.

  4. Serine phosphorylation of syndecan-2 proteoglycan cytoplasmic domain

    Oh, E S; Couchman, J R; Woods, A

    1997-01-01

    Protein kinase C (PKC) is involved in cell-matrix and cell-cell adhesion, and the cytoplasmic domain of syndecan-2 contains two serines (residues 197 and 198) which lie in a consensus sequence for phosphorylation by PKC. Other serine and threonine residues are present but not in a consensus...... sequence. We investigated phosphorylation of syndecan-2 cytoplasmic domain by PKC, using purified GST-syndecan-2 fusion proteins and synthetic peptides corresponding to regions of the cytoplasmic domain. A synthetic peptide encompassing the entire cytoplasmic domain of syndecan-2 was phosphorylated by PKC...... cytoplasmic domain peptides were monomeric, with 2 mol/mol serine phosphorylation. At higher concentrations, however, the peptides formed dimers, with only 0.5 mol/mol phosphorylation. Concentration-dependent dimerization was not altered by phosphorylation. Phosphorylation is, therefore, dependent on the...

  5. Abortion in Islamic countries--legal and religious aspects.

    Asman, Oren

    2004-01-01

    The debate over abortion is still controversial as ever. As one of every four people in the world is of the Muslim religion, it is important to learn more about the Islamic point of view toward this dilemma in medical ethics. The first part of this paper gives a general view of the sources of Islamic law and discusses modern developments in Islamic medical ethics regarding abortion. The second part focuses on the legal aspects of abortion in different Islamic states, dealing with the need to supply solutions to women who for different reasons wish to abort and at the same time enact laws that would not contradict Islamic principles. A study of three Muslim states (Egypt, Kuwait and Tunisia) demonstrates three different approaches toward legalizing abortion--a conservative approach, a more lenient approach, and a liberal one--all within Islamic oriented states. This leads to a conclusion that a more liberal attitude regarding abortion is possible in Islamic states, as long as traditional principles are taken into account. PMID:15163077

  6. From pragmatism to politics: a qualitative study of abortion providers.

    Wear, Delese

    2002-01-01

    Twenty-eight years after the United State Supreme Court issued its landmark Roe v. Wade, the struggle continues to ensure that all women have the full range of reproductive choices, including abortion. While the struggle can be addressed through its political, religious, and medical dimensions, it also can be examined through the perspectives of those who actually provide abortions. This paper examines the perspectives of physician abortion providers to understand more fully their motivations, the quality of their personal and professional lives, their views on the future of abortion services, and their recommendations for undergraduate and residency medical education. Such questions are often best answered through qualitative inquiry, particularly when the subject at hand has had little interpretive scrutiny, lacks theoretical understandings, and remains in general an under-investigated phenomenon. Because abortion providers and the work they do fit those criteria, a qualitative study of physician providers in Ohio was undertaken. This paper is divided into the following sections: a literature review of abortion services in the United States, methods, interview data and discussion, and last, recommendations and conclusions. PMID:12555805

  7. Research on lidocaine in the application of induced abortion

    Hai-Tao Tong

    2015-01-01

    Objective:To observe the effect of lidocaine in the application of induced abortion.Methods:A total of 120 pregnant women with 6-10 week gestational age and ASA I-II level who were volunteered to receive induced abortions from January, 2010 to January, 2013 were included in the study, among which 60 cases were given lidocaine during the operation and served as the observation group, while 60 cases were not given lidocaine during the operation and served as the control group. The heart rate, blood pressure, the change of oxygen saturation, pain, and the occurrence of abortion syndrome before and after operation between the two groups were compared.Results:The fineness rates of analgesia and anesthesia evaluation in the observation group were significantly higher than those in the control group (P0.05). The postoperative heart rate and blood pressure in the control group were significantly lower than those before operation and in the observation group with a slow recovery (P0.05). The occurrence rate of abortion syndrome in the observation group was significantly lower than that in the control group (P<0.05). Conclusions:Application of lidocaine in the induced abortion can relieve the pain and reduce the occurrence rate of abortion syndrome with a simple and safe operation; therefore, it deserves to be widely recommended.

  8. Nation's most onerous abortion restrictions challenged in Mississippi court.

    1994-02-25

    A lawsuit was filed in Mississippi on February 17, 1994, which challenges several aspects of Mississippi's abortion law. The case, Pro-choice Mississippi vs. Fordice, will seek to determine if the state's 24-hour delay and mandated information for abortion-seekers, 2-parent consent or court approval for young women, and licensing requirements for abortion providers violate the state Constitution both as written and as applied. At issue here are rights of privacy, bodily integrity, freedom of conscience, and the right to make a medical decision free from government interference. The 24-hour delay went into effect in August 1992. The parental consent was enacted in 1986 and went into effect in May 1993 because of another lawsuit, and the licensing requirements have been effective since their passage in November 1991 and have prevented qualified abortion providers from practicing in the State. The effect of these measures has been to reduce the number of abortions performed, especially for women with less than a high school education and to increase by an estimated 18% the number of second trimester abortions performed. PMID:12345514

  9. Abortion in Chile: the practice under a restrictive regime.

    Casas, Lidia; Vivaldi, Lieta

    2014-11-01

    This article examines, from a human rights perspective, the experience of women, and the practices of health care providers regarding abortion in Chile. Most abortions, as high as 100,000 a year, are obtained surreptitiously and clandestinely, and income and connections play a key role. The illegality of abortion correlates strongly with vulnerability, feelings of guilt and loneliness, fear of prosecution, physical and psychological harm, and social ostracism. Moreover, the absolute legal ban on abortion has a chilling effect on health care providers and endangers women's lives and health. Although misoprostol use has significantly helped to prevent greater harm and enhance women's agency, a ban on sales created a black market. Against this backdrop, feminists have taken action in aid of women. For instance, a feminist collective opened a telephone hotline, Linea Aborto Libre (Free Abortion Line), which has been crucial in informing women of the correct and safe use of misoprostol. Chile is at a crossroads. For the first time in 24 years, abortion law reform seems plausible, at least when the woman's life or health is at risk and in cases of rape and fetal anomalies incompatible with life. The political scenario is unfolding as we write. Congressional approval does not mean automatic enactment of a new law; a constitutional challenge is highly likely and will have to be overcome.

  10. Five-Segment Booster (FSB) Abort to Orbit (ATO) Studies

    Tobias, Mark; Sauvageau, Donald R.; Hines, Mark; Geiser, Norman L.; Cash, Steve (Technical Monitor)

    2002-01-01

    The Five Segment Booster (FSB) concept has been evolving for a number of years as a means to enhance the overall safety and reliability of the Space Shuttle system by minimizing the need to fly the more challenging Return to Launch Site (RTLS) and Transoceanic Abort Landing (TAL) abort profiles. The initial evaluation of the FSB concept was conducted in 1996 to determine the feasibility of the FSB in achieving transatlantic abort leading TAL from the pad, thus eliminating the return to launch site (RTLS) abort mode. The initial study was conducted by ATK Thiokol and did show the potential for the FSB to eliminate the RTLS abort mode. Later Rockwell (now Boeing) conducted a similar study utilizing FSB performance characteristics and verified that the FSB could indeed achieve TAL from the pad, thereby eliminating the necessity for the RTLS abort. The purpose of this paper is to discuss the details of the enhancements achieved through the internally funded study conducted by Boeing and ATK Thiokol. To better understand the enhancements that were addressed as part of this follow-on study, some background on what was achieved in the Phase A study is appropriate.

  11. [Abortion in Colombia. Medical, legal and socioeconomic aspects].

    Umaña, A O

    1973-01-01

    Abortion is a social problem and criminal sanctions are very ineffective in limiting it and are seldom applied (133 legal actions vs. 65,600 cases of induced abortion in 1965). Abortion is a social disease, as are prostitution, juvenile delinquency, drug abuse, and so far has been an insoluble problem. Colombian laws should be modified to reflect reality. Sex education must be emphasized, because ignorance is one of the main causes of abortion. Leniency should be applied toward women who cooperate with the authorities in identifying the person who performed an abortion. Legalization of abortion and enforcement of strict laws against it are considered as possible solutions, but both are rejected. The former is regarded as morally unacceptable and as imposing an excessive burden on scarce health services, the latter as even worse, imposing an equivalent burden on the court system, without s olving either health or social problems. The best and probably only solution is to improve education in family planning, to promote knowledge and motivation to enable the population to make sound and responsible decisions. PMID:4804875

  12. Why Governments That Fund Elective Abortion Are Obligated to Attempt a Reduction in the Elective Abortion Rate.

    Dumsday, Travis

    2016-03-01

    If elective abortion is publicly funded, then the government is obligated to take active measures designed to reduce its prevalence. I present two arguments for that conclusion. The first argument is directed at those pro-choice thinkers who hold that while some or all elective abortions are morally wrong, they still ought to be legally permitted and publicly subsidized. The second argument is directed at pro-choice thinkers who hold that there is nothing morally wrong with elective abortion and that it should be both legally permitted and publicly subsidized. The second argument employs premises that generalize beyond the abortion debate and that may serve to shed light on broader questions concerning conscience and the requirements of political compromise in a democracy.

  13. Continuous Improvements to East Coast Abort Landings for Space Shuttle Aborts

    Butler, Kevin D.

    2003-01-01

    Improvement initiatives in the areas of guidance, flight control, and mission operations provide increased capability for successful East Coast Abort Landings (ECAL). Automating manual crew procedures in the Space Shuttle's onboard guidance allows faster and more precise commanding of flight control parameters needed for successful ECALs. Automation also provides additional capability in areas not possible with manual control. Operational changes in the mission concept allow for the addition of new landing sites and different ascent trajectories that increase the regions of a successful landing. The larger regions of ECAL capability increase the safety of the crew and Orbiter.

  15. Knowledge Level of Gynecologists and Midwives of Yazd Concerning Rules and Regulations of Therapeutic Abortion(Legal and Criminal Abortion

    M Ghadipasha

    2011-05-01

    Full Text Available Introduction: Abortion has always been a controversial issue and all religions, humanistic and medical communities have opposed it . The complications of illegal abortion are one of the most common reasons of hospital admission in developing countries. W.H.O estimates that the one eight of all pregnancy deaths is due to illegal abortion. Lack of knowledge of the medical team about the abortion regulations and rules can endanger the pregnant mothers life and also create certain problems for medical communities . Methods: This cross- sectional study was conducted in 2007 and included 110 gynecologists and midwives in Yazd who were studied by census method. Data was collected via self-made questionnaire and data analysis was done by software SPSS program and statistical tests included square K and T test. Results : Of the total of 110 patients, 16.4% were gynecologists and 83.3% were midwives, 31.8% worked in academic centers and 68.2% were employed at other centers. The awareness level of 25.5% was good. There was a meaningful difference between the awareness level of academic employed and nonacademic employed and also between those who had studied abortion rules regulations. Conclusion: As 74.5% of the study population had low levels of awareness about the abortion rules, education of midwives & gynecologists about rules & regulations is strongly recommended as it not only helps women's health, but also decreases their legal problems.

  16. Structural determinants of the abortion rate: a cross-societal analysis.

    Trent, K; Hoskin, A W

    1999-01-01

    Data for a sample of 89 countries are used to examine societal-level predictors of the legal status of abortion and its incidence as indicated by abortion rates. Measures of socioeconomic development, women's labor force participation, and dominant religion are considered as predictors of abortion. Logistic regression analysis reveals that socioeconomic development has a positive effect on the probability of abortion being legal. Both a greater dominance of Catholicism and Islam in a society reduce the probability that abortion is legal. Results of tobit analyses show that development has curvilinear effects on abortion rates, with lower rates of abortion at both the lower and higher ends of development. Findings also indicate a positive effect of female labor force participation on the abortion rate that initially grows stronger with increases in socioeconomic development, but weakens with further increases. Finally, a greater proportion of Catholics in a population lowers the abortion rate. PMID:10842502

    2012-12-01

    Full Text Available A luta pela legalização do aborto pouco tem avançado no Brasil. O artigo observa a importância política da questão. Por um lado, é um índice da laicidade do Estado, que, por sua vez, é condição necessária para a vigência da democracia. Por outro, na ausência desse direito a cidadania das mulheres é incompleta. O forte peso da Igreja Católica na vida política brasileira não é suficiente para explicar a paralisia no que se refere à questão.The struggle to legalize abortion in Brazil has advanced very little. The article focuses on the political importance of the issue. On the one hand, it is an index of the laicism of the State, which in turn is a necessary condition for the exercise of democracy. On the other hand, in the absence of this right, the citizenship of women is incomplete. The weight of the Catholic Church in Brazilian political life is not enough to explain the paralysis with regard to the question.

  18. Mechanisms for independent cytoplasmic inheritance of mitochondria and plastids in angiosperms.

    Nagata, Noriko

    2010-03-01

    The inheritance of mitochondria and plastids in angiosperms has been categorized into three modes:maternal, biparental and paternal. Many mechanisms have been proposed for maternal inheritance, including: (1) physical exclusion of the organelle itself during pollenmitosis I (PMI); (2) elimination of the organelle by formation of enucleated cytoplasmic bodies (ECB); (3) autophagic degradation of organelles during male gametophyte development; (4) digestion of the organelle after fertilization; and (5)--the most likely possibility--digestion of organellar DNA in generative cells just after PMI. In detailed cytological observations, the presence or absence of mitochondrial and plastid DNA in generative cells corresponds to biparental/paternal inheritance or maternal inheritance of the respective organelle examined genetically. These improved cytological observations demonstrate that the replication or digestion of organellar DNA in young generative cells just after PMI is a critical point determining the mode of cytoplasmic inheritance. This review describes the independent control mechanisms in mitochondria and plastids that lead to differences in cytoplasmic inheritance in angiosperms. PMID:20196234

  19. CTP synthase forms cytoophidia in the cytoplasm and nucleus

    CTP synthase is an essential metabolic enzyme responsible for the de novo synthesis of CTP. Multiple studies have recently showed that CTP synthase protein molecules form filamentous structures termed cytoophidia or CTP synthase filaments in the cytoplasm of eukaryotic cells, as well as in bacteria. Here we report that CTP synthase can form cytoophidia not only in the cytoplasm, but also in the nucleus of eukaryotic cells. Both glutamine deprivation and glutamine analog treatment promote formation of cytoplasmic cytoophidia (C-cytoophidia) and nuclear cytoophidia (N-cytoophidia). N-cytoophidia are generally shorter and thinner than their cytoplasmic counterparts. In mammalian cells, both CTP synthase 1 and CTP synthase 2 can form cytoophidia. Using live imaging, we have observed that both C-cytoophidia and N-cytoophidia undergo multiple rounds of fusion upon glutamine analog treatment. Our study reveals the coexistence of cytoophidia in the cytoplasm and nucleus, therefore providing a good opportunity to investigate the intracellular compartmentation of CTP synthase. - Highlights: • CTP synthase forms cytoophidia not only in the cytoplasm but also in the nucleus. • Glutamine deprivation and Glutamine analogs promotes cytoophidium formation. • N-cytoophidia exhibit distinct morphology when compared to C-cytoophidia. • Both CTP synthase 1 and CTP synthase 2 form cytoophidia in mammalian cells. • Fusions of cytoophidia occur in the cytoplasm and nucleus

Using live imaging, we have observed that both C-cytoophidia and N-cytoophidia undergo multiple rounds of fusion upon glutamine analog treatment. Our study reveals the coexistence of cytoophidia in the cytoplasm and nucleus, therefore providing a good opportunity to investigate the intracellular compartmentation of CTP synthase. - Highlights: • CTP synthase forms cytoophidia not only in the cytoplasm but also in the nucleus. • Glutamine deprivation and Glutamine analogs promotes cytoophidium formation. • N-cytoophidia exhibit distinct morphology when compared to C-cytoophidia. • Both CTP synthase 1 and CTP synthase 2 form cytoophidia in mammalian cells. • Fusions of cytoophidia occur in the cytoplasm and nucleus.
