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

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

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

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

    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.

    Rice with LD-type cytoplasmic male sterility (CMS) possesses the cytoplasm of 'Lead Rice' and its fertility is recovered by a nuclear fertility restorer gene Rf1. Rf1 promotes processing of a CMS-associated mitochondrial RNA of atp6-orf79, which consists of atp6 and orf79, in BT-CMS with the cytoplasm of 'Chinsurah Boro II'. In this study, we found that LD-cytoplasm contained a sequence variant of orf79 downstream of atp6. Northern blot analysis showed that atp6-orf79 RNA of LD-cytoplasm was co-transcribed and was processed in the presence of Rf1 in the same manner as in BT-cytoplasm. Western blot analysis showed that the ORF79 peptide did not accumulate in an LD-CMS line, while ORF79 accumulated in a BT-CMS line and was diminished by Rf1. These results suggest that accumulation of ORF79 is not the cause of CMS in LD-cytoplasm and the mechanism of male-sterility induction/fertility restoration in LD-CMS is different from that in BT-CMS.

    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.

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

    A comprehensive understanding of CMS/Rf system enabled by modern omics tools and technologies considerably improves our ability to harness hybrid technology for enhancing the productivity of field crops. Harnessing hybrid vigor or heterosis is a promising approach to tackle the current challenge of sustaining enhanced yield gains of field crops. In the context, cytoplasmic male sterility (CMS) owing to its heritable nature to manifest non-functional male gametophyte remains a cost-effective system to promote efficient hybrid seed production. The phenomenon of CMS stems from a complex interplay between maternally-inherited (mitochondrion) and bi-parental (nucleus) genomic elements. In recent years, attempts aimed to comprehend the sterility-inducing factors (orfs) and corresponding fertility determinants (Rf) in plants have greatly increased our access to candidate genomic segments and the cloned genes. To this end, novel insights obtained by applying state-of-the-art omics platforms have substantially enriched our understanding of cytoplasmic-nuclear communication. Concomitantly, molecular tools including DNA markers have been implicated in crop hybrid breeding in order to greatly expedite the progress. Here, we review the status of diverse sterility-inducing cytoplasms and associated Rf factors reported across different field crops along with exploring opportunities for integrating modern omics tools with CMS-based hybrid breeding.

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

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

    Although cytoplasmic male sterility (CMS) is widely used for developing pepper hybrids, its molecular mechanism remains unclear. In this study, we used a high-throughput proteomics method called label-free to compare protein abundance across a pepper CMS line (A-line) and its isogenic maintainer line (B-line). Data are available via ProteomeXchange with identifier PXD006104. Approximately 324 differentially abundant protein species were identified and quantified; among which, 47 were up-accumulated and 140 were down-accumulated in the A-line; additionally, 75 and 62 protein species were specifically accumulated in the A-line and B-line, respectively. Protein species involved in pollen exine formation, pyruvate metabolic processes, the tricarboxylic acid cycle, the mitochondrial electron transport chain, and oxidative stress response were observed to be differentially accumulated between A-line and B-line, suggesting their potential roles in the regulation of pepper pollen abortion. Based on our data, we proposed a potential regulatory network for pepper CMS that unifies these processes. Artificial emasculation is a major obstacle in pepper hybrid breeding for its high labor cost and poor seed purity. While the use of cytoplasmic male sterility (CMS) in hybrid system is seriously frustrated because a long time is needed to cultivate male sterility line and its isogenic restore line. Transgenic technology is an effective and rapid method to obtain male sterility lines and its widely application has very important significance in speeding up breeding process in pepper. Although numerous studies have been conducted to select the genes related to male sterility, the molecular mechanism of cytoplasmic male sterility in pepper remains unknown. In this study, we used the high-throughput proteomic method called "label-free", coupled with liquid chromatography-quadrupole mass spectrometry (LC-MS/MS), to perform a novel comparison of expression profiles in a CMS pepper line

    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 M/sub 4/ 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.

    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 M 4 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.)

    @@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.

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

    A wild-abortive-type (WA) cytoplasmic male sterility (CMS) has been almost exclusively used for breeding three-line hybrid rice. Many indica cultivars are known to carry restorer genes for WA-CMS lines and cannot be used as maintainer lines. Especially elite indica cultivars IR24 and IR64 are known to be restorer lines for WA-CMS lines, and are used as male parents for hybrid seed production. If we develop CMS IR24 and CMS IR64, the combination of F1 pairs in hybrid rice breeding programs will be greatly broadened. For production of CMS lines and restorer lines of IR24 and IR64, we employed Chinese wild rice (CW)-type CMS/Restorer of fertility 17 (Rf17) system, in which fertility is restored by a single nuclear gene, Rf17. Successive backcrossing and marker-assisted selection of Rf17 succeeded to produce completely male sterile CMS lines and fully restored restorer lines of IR24 and IR64. CW-cytoplasm did not affect agronomic characteristics. Since IR64 is one of the most popular mega-varieties and used for breeding of many modern varieties, the CW-CMS line of IR64 will be useful for hybrid rice breeding.

    Full Text Available Cytoplasmic male sterility (CMS is a cornerstone of hybrid production in many crops. In three-line hybrid systems, use of CMS, maintainer, and fertility restorer lines is necessary for production of hybrid seeds. Limited resources of CMS and low variation of CMS lines cause genetic vulnerability to pathogens. Therefore, diversifying the CMS sources is indispensible for a sustainable production system of hybrid seed. In this study, we attempted for the first time to transfer CMS into maintainer line Yosen B in restricted generations using the marker-assisted backcrossing (MABC method. The resultant F hybrid of IR68897 A/Yosen B cross was backcrossed to Yosen B, and CMS plants in each backcross generation (from BCF to BCF were selected based on phenotyping test and MABC. Molecular assessment of backcross progenies was conducted using a mitochondrial CMS-specific marker and 34 polymorphic nuclear simple-sequence repeat (SSR markers in early generations (from BCF to BCF and was continued using 9 additional SSRs and 82 inter-simple sequence repeat (ISSR markers in BCF. A MABC strategy could successfully recover the recurrent parent genome (RPG in BCF generation, and decreased heterozygosity of final CMS plants. Restorability test with known wild-abortive restorer lines (viz. IR36 and IR24 showed that combination of Yosen A × IR24 could produce highly fertile F hybrid. Evaluation of some important agronomic traits of the final CMS line (BCF at field condition showed that it was comparable to the original maintainer fertile counterpart. Phenotypic and marker-assisted selections could considerably decrease the time needed for full recovery of RPG so that final CMS line could show a high similarity to original fertile counterpart.

    Full Text Available Bacterial blight (BB, caused by Xanthomonas oryzae pv.oryzae is one among the major diseases in rice, which in severe condition cause losses up to 60% in total yield. Marker assisted pyramiding of three broad spectrum BB resistance genes (xa5, xa13, and Xa21 in prominent rice varieties is the most economical and effective strategy for the management of the BB disease. We report here the pyramiding of three genes (xa5, xa13, and Xa21 in maintainer lines (CO 2B, CO 23B, and CO 24B of three promising wild abortive cytoplasmic male sterile lines (CO 2A, CO 23A, and CO 24A through functional markers assisted back cross breeding. IRBB60 with xa5, xa13, and Xa21 genes is used as a donor parent. BC2F1 and BC2F2 generations from a cross of CO 2B, CO 23B, and CO 24B with IRBB60 were evaluated for bacterial blight and non-fertility restoration. In BC2F1, plants with all three resistance genes (xa5, xa13, and Xa21 and high parent genome recovery was identified. In BC2F2, plants with all resistance genes and without fertility restorer (Rf3 and Rf4 were selected. Based on agronomic traits, BB resistance and maintenance of sterility, two plants each in CO 2B × IRBB60, CO 24B × IRBB60 and one plant in CO 23B × IRBB60 combinations were identified. The identified lines were crossed with respective male sterile lines for conversion of improved B line into CMS line through back-crossing, in addition to selfing. The plants with high recurrent genome and phenotypically similar to parental lines and sterile are being used for the hybrid rice development program. Currently, using these lines (improved CMS line, test crosses were made to develop new rice hybrids. Hybrids combinations viz., CO 23A × AD08009R and CO 24A × IET20898R were found to be stable at different locations with high yield. The R line used in this study has been introgressed with xa5, xa13, and Xa21 genes in a separate breeding program. These new hybrids with resistance against bacterial blight

    Full Text Available Cytoplasm has substantial genetic effects on progeny and is important for yield improvement in rice breeding. Studies on the cytoplasmic effects of cytoplasmic male sterility (CMS show that most types of CMS have negative effects on yield-related traits and that these negative effects vary among CMS. Some types of genic male sterility (GMS, including photo-thermo sensitive male sterility (PTMS, have been widely used in rice breeding, but the cytoplasmic effects of GMS remain unknown. Here, we identified a GMS mutant line, h2s, which exhibited small, white anthers and failed to produce mature pollen. Unlike CMS, the h2s had significant positive cytoplasmic effects on the seed set rate, weight per panicle, yield, and general combining ability (GCA for plant height, seed set rate, weight per panicle, and yield. These effects indicated that h2s cytoplasm may show promise for the improvement of rice yield. Genetic analysis suggested that the phenotype of h2s was controlled by a single recessive locus. We mapped h2s to a 152 kb region on chromosome 6, where 22 candidate genes were predicted. None of the 22 genes had previously been reported to be responsible for the phenotypes of h2s. Sequencing analysis showed a 12 bp deletion in the sixth exon of Loc_Os06g40550 in h2s in comparison to wild type, suggesting that Loc_Os06g40550 is the best candidate gene. These results lay a strong foundation for cloning of the H2S gene to elucidate the molecular mechanism of male reproduction.

    In crosses between evolutionarily diverged populations, genomic incompatibilities may result in sterile hybrids, indicating evolution of reproductive isolation. In several plant families, crosses within a population can also lead to male sterile progeny because of conflict between the maternally and biparentally inherited genomes. We examined hybrid fertility between subspecies of the perennial outcrossing self-incompatible Lyrate rockcress (Arabidopsis lyrata) in large reciprocal F2 progenies and three generations of backcrosses. In one of the reciprocal F2 progenies, almost one-fourth of the plants were male-sterile. Correspondingly, almost one-half of the plants in one of the four reciprocal backcross progenies expressed male sterility. In an additional four independent F2 and backcross families, three segregated male sterility. The observed asymmetrical hybrid incompatibility is attributable to male sterility factors in one cytoplasm, for which the other population lacks effective fertility restorers. Genotyping of 96 molecular markers and quantitative trait locus mapping revealed that only 60% of the plants having the male sterile cytoplasm and lacking the corresponding restorers were phenotypically male-sterile. Genotyping data showed that there is only one restorer locus, which mapped to a 600-kb interval at the top of chromosome 2 in a region containing a cluster of pentatricopeptide repeat genes. Male fertility showed no trade-off with seed production. We discuss the role of cytoplasm and genomic conflict in incipient speciation and conclude that cytoplasmic male sterility-lowering hybrid fitness is a transient effect with limited potential to form permanent reproductive barriers between diverged populations of hermaphrodite self-incompatible species.

    Full Text Available The results of our experiments executed to obtain tobacco male sterile lines through interspecific hybridization are summarized. Ten wild species from the genus Nicotiana: N. excelsior (exc, N. amplexicaulis (amp, N. rustica (rus, Nicotianaglauca (gla, N. velutina (vel, N. benthamiana (ben, N. maritima (mar, N. paniculata (pan, N. longiflora (lon and N. africana (afr were used as cytoplasmic donors and N. tabacum, cv. HarmanliiskaBasma (HB as a donor of the nucleus. Genetic effects of cytoplasmic-nuclear interaction of the studied species are discussed. Our results suggested that cytoplasmic male sterility (CMS was expressed when the cytoplasms of the above mentioned wild Nicotiana species were combined with the nucleus of N. tabacum. The 10 sources of CMS obtained in tobacco were characterized by altered flower phenotypes. Flowers are classified into types according the stamen, pistil and corolla modification. All these CMS sources were backcrossed to Oriental tobaccos, cvs. Tekne, Nevrokop B-12, Kroumovgrad 90 and Djebel 576, to develop corresponding CMS lines. The investigated cytoplasms produced compete male sterility in all those cultivars. The CMS lines preserved flower types, specific for every “sterile” cytoplasm. The extent of male organ modifications varied from apparently normal (but pollenless stamens in CMS (pan, (afr, some plants of (vel (mar through different degrees of malformations (shriveled anther on shortened filaments (lon, pinnate-like anthers on filaments of normal length (amp, petal - (ben, pistil- or stigma-like structures (rus, (gla to lack of male reproductive organs in (exc and in some plants of (vel, (mar, (rus and (gla. Most of the above mentioned cytoplasms had normal female gametophyte and good seed productivity. Alterations of the pistils were observed in CMS (rus, (exc and (ben causing reduction of the seed set. Electrophoresis of seed proteins of the tobacco cultivars and their CMS lines also suggested that

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

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

    Weedy rice infests paddy fields worldwide at an alarmingly increasing rate. There is substantial evidence indicating that many weedy rice forms originated from or are closely related to cultivated rice. There is suspicion that the outbreak of weedy rice in China may be related to widely grown hybrid rice due to its heterosis and the diversity of its progeny, but this notion remains unsupported by direct evidence. We screened weedy rice accessions by both genetic and molecular marker tests for the cytoplasmic male sterility (CMS) genes (Wild abortive, WA, and Boro type, BT) most widely used in the production of indica and japonica three-line hybrid rice as a diagnostic trait of direct parenthood. Sixteen weedy rice accessions of the 358 tested (4.5%) contained the CMS-WA gene; none contained the CMS-BT gene. These 16 accessions represent weedy rices recently evolved from maternal hybrid rice derivatives, given the primarily maternal inheritance of this trait. Our results provide key direct evidence that hybrid rice can be involved in the evolution of some weedy rice accessions, but is not a primary factor in the recent outbreak of weedy rice in China.

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

    A novel open reading frame (ORF) identified and cloned from the A4 cytoplasm of Cajanus cajanifolius induced partial to complete male sterility when introduced into Arabidopsis and tobacco. Pigeonpea (Cajanus cajan L. Millsp.) is the only legume known to have commercial hybrid seed technology based on cytoplasmic male sterility (CMS). We identified a novel ORF (orf147) from the A4 cytoplasm of C. cajanifolius that was created via rearrangements in the CMS line and co-transcribes with the known and unknown sequences. The bi/poly-cistronic transcripts cause gain-of-function variants in the mitochondrial genome of CMS pigeonpea lines having distinct processing mechanisms and transcription start sites. In presence of orf147, significant repression of Escherichia coli growth indicated its toxicity to the host cells and induced partial to complete male sterility in transgenic progenies of Arabidopsis thaliana and Nicotiana tabacum where phenotype co-segregated with the transgene. The male sterile plants showed aberrant floral development and reduced lignin content in the anthers. Gene expression studies in male sterile pigeonpea, Arabidopsis and tobacco plants confirmed down-regulation of several anther biogenesis genes and key genes involved in monolignol biosynthesis, indicative of regulation of retrograde signaling. Besides providing evidence for the involvement of orf147 in pigeonpea CMS, this study provides valuable insights into its function. Cytotoxicity and aberrant programmed cell death induced by orf147 could be important for mechanism underlying male sterility that offers opportunities for possible translation for these findings for exploiting hybrid vigor in other recalcitrant crops as well.

    Nuclear genome substitutions between subspecies can lead to cytoplasmic male sterility (CMS) through incompatibility between nuclear and mitochondrial genomes. Boro-Taichung (BT)-type CMS rice was obtained by substituting the nuclear genome of Oryza sativa subsp. indica cultivar Chinsurah Boro II with that of Oryza sativa subsp. japonica cultivar Taichung 65. In BT-type CMS rice, the mitochondrial gene orf79 is associated with male sterility. A complete sequence of the Boro-type mitochondrial genome responsible for BT-type CMS has not been determined to date. Here, we used pyrosequencing to construct the Boro-type mitochondrial genome. The contiguous sequences were assembled into five circular DNA molecules, four of which could be connected into a single circle. The two resulting subgenomic circles were unable to form a reliable master circle, as recombination between them was scarcely detected. We also found an unequal abundance of DNA molecules for the two loci of atp6. These results indicate the presence of multi-partite DNA molecules in the Boro-type mitochondrial genome. Expression patterns were investigated for Boro-type mitochondria-specific orfs, which were not found in the mitochondria from the standard japonica cultivar Nipponbare. Restorer of fertility 1 (RF1)-dependent RNA processing has been observed in orf79-containing RNA but was not detected in other Boro-type mitochondria-specific orfs, supporting the conclusion that orf79 is a unique CMS-associated gene in Boro-type mitochondria.

    A global view of differential expression of genes in CMS-D8 of cotton was presented in this study which will facilitate the understanding of cytoplasmic male sterility in cotton. Cytoplasmic male sterility (CMS) is a maternally inherited trait in higher plants which is incapable of producing functional pollen. However, the male fertility can be restored by one or more nuclear-encoded restorer genes. A genome-wide transcriptome analysis of CMS and restoration in cotton is currently lacking. In this study, Affymetrix GeneChips© Cotton Genome Array containing 24,132 transcripts was used to compare differentially expressed (DE) genes of flower buds at the meiosis stage between CMS and its restorer cotton plants conditioned by the D8 cytoplasm. A total of 458 (1.9 %) of DE genes including 127 up-regulated and 331 down-regulated ones were identified in the CMS-D8 line. Quantitative RT-PCR was used to validate 10 DE genes selected from seven functional categories. The most frequent DE gene group was found to encode putative proteins involved in cell wall expansion, such as pectinesterase, pectate lyase, pectin methylesterase, glyoxal oxidase, polygalacturonase, indole-3-acetic acid-amino synthetase, and xyloglucan endo-transglycosylase. Genes in cytoskeleton category including actin, which plays a key role in cell wall expansion, cell elongation and cell division, were also highly differentially expressed between the fertile and CMS plants. This work represents the first study in utilizing microarray to identify CMS-related genes by comparing overall DE genes between fertile and CMS plants in cotton. The results provide evidence that many CMS-associated genes are mainly involved in cell wall expansion. Further analysis will be required to elucidate the molecular mechanisms of male sterility which will facilitate the development of new hybrid cultivars in cotton.

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

    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.

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

    Directory of Open Access Journals (Sweden)

    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

    Male-sterile (S) cytoplasm of onion is an alien cytoplasm introgressed into onion in antiquity and is widely used for hybrid seed production. Owing to the biennial generation time of onion, classical crossing takes at least 4 years to classify cytoplasms as S or normal (N) male-fertile. Molecular markers in the organellar DNAs that distinguish N and S cytoplasms are useful to reduce the time required to classify onion cytoplasms. In this research, we completed next-generation sequencing of the chloroplast DNAs of N- and S-cytoplasmic onions; we assembled and annotated the genomes in addition to identifying polymorphisms that distinguish these cytoplasms. The sizes (153 538 and 153 355 base pairs) and GC contents (36.8%) were very similar for the chloroplast DNAs of N and S cytoplasms, respectively, as expected given their close phylogenetic relationship. The size difference was primarily due to small indels in intergenic regions and a deletion in the accD gene of N-cytoplasmic onion. The structures of the onion chloroplast DNAs were similar to those of most land plants with large and small single copy regions separated by inverted repeats. Twenty-eight single nucleotide polymorphisms, two polymorphic restriction-enzyme sites, and one indel distributed across 20 chloroplast genes in the large and small single copy regions were selected and validated using diverse onion populations previously classified as N or S cytoplasmic using restriction fragment length polymorphisms. Although cytoplasmic male sterility is likely associated with the mitochondrial DNA, maternal transmission of the mitochondrial and chloroplast DNAs allows for polymorphisms in either genome to be useful for classifying onion cytoplasms to aid the development of hybrid onion cultivars.

    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; Pmale fertility are due to up-regulation of fertility-restoring genes by a high level of water availability. Comparative MSAP-analysis of DNA of male-sterile and male-fertile test-cross hybrids using HpaII/MspI restrictases and primers to polygalacturonase gene ADPG2, which is required for cell separation during reproductive development, and gene MYB46, the transcription factor regulating secondary wall biosynthesis, revealed differences in the number and the length of amplified fragments. Changes in the methylation of these genes in conditions of drought stress are apparently the reason for male sterility of sorghum 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.

    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.

    Pigeonpea [Cajanus cajan (L.) Millsp.] is a unique food legume because of its partial (20-30%) outcrossing nature, which provides an opportunity to breed commercial hybrids. To achieve this, it is essential to have a stable male-sterility system. This paper reports the selection of a cytoplasmic-nuclear male-sterility (CMS) system derived from an interspecific cross between a wild relative of pigeonpea (Cajanus sericeus Benth. ex. Bak.) and a cultivar. This male-sterility source was used to breed agronomically superior CMS lines in early (ICPA 2068), medium (ICPA 2032), and late (ICPA 2030) maturity durations. Twenty-three fertility restorers and 30 male-sterility maintainers were selected to develop genetically diverse hybrid combinations. Histological studies revealed that vacuolation of growing tetrads and persistence of tetrad wall were primary causes of the manifestation of male sterility. Genetic studies showed that 2 dominant genes, of which one had inhibitory gene action, controlled fertility restoration in the hybrids. The experimental hybrids such as TK 030003 and TK 030009 in early, ICPH 2307 and TK 030625 in medium, and TK 030861 and TK 030851 in late maturity groups exhibited 30-88% standard heterosis in multilocation trials.

    Full Text Available Cytoplasmic male sterility (CMS has been exploited in the commercial pigeonpea [ (L. Millsp.] hybrid breeding system; however, the molecular mechanism behind this system is unknown. To understand the underlying molecular mechanism involved in A CMS system derived from (Haines Maesen, 34 mitochondrial genes were analyzed for expression profiling and structural variation analysis between CMS line (ICRISAT Pigeonpea A line, ICPA 2039 and its cognate maintainer (ICPB 2039. Expression profiling of 34 mitochondrial genes revealed nine genes with significant fold differential gene expression at ≤ 0.01, including one gene, , with 1366-fold higher expression in CMS line as compared with the maintainer. Structural variation analysis of these mitochondrial genes identified length variation between ICPA 2039 and ICPB 2039 for (subunit of gene. Sanger sequencing of and genes in the CMS and the maintainer lines identified two single nucleotide polymorphisms (SNPs in upstream region of and a deletion of 10 bp in in the CMS line. Protein structure evaluation showed conformational changes in predicted protein structures for between ICPA 2039 and ICPB 2039 lines. All above analyses indicate association of gene with the CMS for A cytoplasm in pigeonpea. Additionally, one polymerase chain reaction (PCR based Indel marker ( has been developed and validated for testing genetic purity of A derived CMS lines to strengthen the commercial hybrid breeding program in pigeonpea.

    Full Text Available Male sterility enabled commercialization of heterosis in rice but low seed set remains a constraint on hybrid dissemination. We evaluated 216 F6 maintainer lines for agronomic and floral characteristics in augmented design and selected 15 maintainer lines, which were testcrossed with IR58025A. Five backcrosses were conducted to transfer cytoplasmic male sterility (CMS to select maintainer lines. Newly-bred BC5:6 CMS lines were evaluated for outcrossing rates and agronomic characteristics. There were highly significant differences among 216 F6 maintainer lines for characteristics whose genotypic variance was higher than environmental variance. The phenotypic coefficient of variation was almost the same as the genotypic coefficient of variation, indicating that most phenotypic variation was due to genetics. There were highly significant differences among CMS lines for number of days to 50% flowering and maturity; stigma exertion; panicle exertion, length and weight; spikelet fertility; tillers per plant; plant height; grains per panicle; grain yield per plant; and 1000-grain weight, but not for pollen and panicle sterility during dry and wet seasons. Three CMS lines (CMS3, CMS12, and CMS14, exhibited high outcrossing rates (56.17%, 51.42% and 48.44%, respectively, which had a highly significant, positive correlation with stigma exertion (0.97, spikelet opening angle (0.82, and panicle exertion (0.95.

    An attempt is being made to establish cytoplasmic organelles transmission during the process of fertilization, by using tobacco grain pollen labelled with leucine 14 C 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

    Full Text Available A total of seven maize inbred lines of different origin and maturity group were used in the trial set up according to the split-plot randomized complete block design in five environments. Each inbred was observed in five variants: original inbred (N; cytoplasmic male sterile C-type (CMS-C; restorer for CMS-C (RfC; cytoplasmic male sterile S-type (CMS-S and restorer for CMS-S (RfS. The objective was to compare grain yield of original inbreds and their CMS and Rf variants and to apply Isoelectric focusing (IEF to determine whether the conversion of original inbreds to their CMS and Rf counterparts have been done completely. Protein markers have shown that conversion of almost all inbreds was done good and completely. Only original inbreds ZPL2 and ZPL5 did not concur on banding patterns with their RfC variants. The type of cytoplasm had a very significant impact on grain yield. Namely, CMS-C counterparts significantly out yielded their CMS-S versions, while the inbreds with C and S cytoplasm over yielded inbreds with N cytoplasm, as well as their RfC and RfS versions.

    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.

    Full Text Available Five suitable maintainer varieties were identifi ed through testcrosses with IR58025A and the transfer of wild abortive cytoplasm was carried out by seven successive backcrosses. Five new CMS lines were developed by this approach in well adapted high yielding improved varietal background such as ‘Nemat’, ‘Neda’, ‘Dasht’, ‘Amol3’ and ‘Champa’. Agronomical characterization and allogamy-associated traits of the fi ve newly developed CMS lines were studied for their interrelationship. Anther length had a signifi cant positive correlation with the duration of glume opening (0.759 and high correlation of (0.698 with the angle between lemma and palea. The results indicated that ‘Nemat’ A, ‘Neda’ A, ‘Dasht’ A are more suitable as parents for hybrid seed production due to their favorable and superior fl oral characteristics in comparison to IR58025A.

    Full Text Available Cabbage (Brassica oleracea L. var. capitata, an important vegetable crop in the Brassicaceae family, is economically important worldwide. In the process of hybrid seed production, Ogura cytoplasmic male sterility (OguCMS, controlled by the mitochondrial gene orf138, has been extensively used for cabbage hybrid production with complete and stable male sterility. To identify the critical genes and pathways involved in the sterility and to better understand the underlying molecular mechanisms, the anther of OguCMS line R2P2CMS and the fertile line R2P2 were used for RNA-seq and iTRAQ (Isobaric Tags for Relative and Absolute Quantitation proteome analysis. RNA-seq analysis generated 13,037,109 to 13,066,594 SE50-clean reads, from the sterile and fertile lines, which were assembled into 36,890 unigenes. Among them, 1,323 differentially expressed genes (DEGs were identified, consisting of 307 up- and 1016 down-regulated genes. For ITRAQ analysis, a total of 7,147 unique proteins were identified, and 833 were differentially expressed including 538 up- and 295 down-regulated proteins. These were mainly annotated to the ribosome, spliceosome and mRNA surveillance pathways. Combined transcriptomic and proteomic analyses identified 22 and 70 genes with the same and opposite expression profiles, respectively. Using KEGG analysis of DEGs, gibberellin mediated signaling pathways regulating tapetum programmed cell death and four different pathways involved in sporopollenin synthesis were identified. Secretion and translocation of the sporopollenin precursors were identified, and the key genes participating in these pathways were all significantly down-regulated in R2P2CMS. Light and transmission electron (TE microscopy revealed fat abnormal tapetum rather than vacuolization and degradation at the tetrad and microspore stages of the OguCMS line. This resulted in the failed deposition of sporopollenin on the pollen resulting in sterility. This study provides a

    Chiasma frequency was recorded in normal and treated [10, 20, 30 Kr γ-rays, 0.2% ethyl methane-sulphonate (EMS) and 10 Kr γ-rays + 0.2% EMS] populations of 7 inbreds and 3 hybrids of pearl millet. Inbreds in general showed lower chiasma frequency than hybrids. However, inbred Bi13B showed the highest chiasma frequency. The male sterile cytoplasm reduced the chaisma frequency and increased the among-plant-variability in the inbreds and, therefore, possibly in the hybrids which had male sterile cytoplasm. γ-rays were more effective than EMS in reducing chiasma frequency. In most of the genotypes 10Kr γ-rays and 0.2% EMS promoted chiasma frequency. The combination treatments showed greater effect than γ-rays and EMS applied individually. Hybrids as a group, showed lower variation for chiasma number than inbreds in response to the mutagenic treatments. (author)

    Hybrid breeding can exploit heterosis and thus offers opportunities to maximize yield quality and resistance traits in crop species. Cytoplasmic male sterility (CMS) is a widely applied tool for efficient hybrid seed production. Encoded in the mitochondrial genome CMS is maternally inherited and thus it can be challenging to apply in breeding schemes of allogamous self incompatible plant species such as perennial ryegrass.

    Full Text Available A “two-line hybrid system” was developed, previously based on thermo-sensitive cytoplasmic male sterility in Aegilops kotschyi (K-TCMS, which can be used in wheat breeding. The K-TCMS line exhibits complete male sterility and it can be used to produce hybrid wheat seeds during the normal wheat-growing season; it propagates via self-pollination at high temperatures. Isobaric tags for relative and absolute quantification-based quantitative proteome and bioinformatics analyses of the TCMS line KTM3315A were conducted under different fertility conditions to understand the mechanisms of fertility conversion in the pollen development stages. In total, 4639 proteins were identified, the differentially abundant proteins that increased/decreased in plants with differences in fertility were mainly involved with energy metabolism, starch and sucrose metabolism, phenylpropanoid biosynthesis, protein synthesis, translation, folding, and degradation. Compared with the sterile condition, many of the proteins that related to energy and phenylpropanoid metabolism increased during the anther development stage. Thus, we suggest that energy and phenylpropanoid metabolism pathways are important for fertility conversion in K-TCMS wheat. These findings provide valuable insights into the proteins involved with anther and pollen development, thereby, helping to further understand the mechanism of TCMS in wheat.

    Full Text Available Use of cytoplasmic male sterility (CMS in hybrid breeding requires effective male fertility-restoring lines. In sorghum, very few restoring lines that can restore fertility in A3 CMS have been reported. To identify the reasons for this deficiency, F1 and F2 hybrids of an A3 CMS line crossed with the line IS1112C, a donor of fertility-restoring (Rf genes for A3 cytoplasm, and testcrosses of fertile plants to A3 CMS lines were grown under contrasting water availability regimes in dryland and irrigated field plots. In the irrigated plots the frequency of fertile plants in testcrosses was twice that in dryland plots (P < 0.05. Fertile plants from the F2 family grown in the irrigated plots showed significantly higher restoration ability than fertile plants from the same family grown in dryland plots. F3 plants from the F2 family grown in irrigated plots yielded on average a sixfold higher frequency of fertile plants in testcrosses than F3 plants derived from dryland plots (P < 0.01. Fertility of testcross hybrids correlated negatively with air vapor pressure deficit (VPD at flowering (r = −0.96; P < 0.01 suggesting that VPD is a trigger for downregulation of Rf genes for A3 cytoplasm.

    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

  4. The impact of Wolbachia, male age and mating history on cytoplasmic incompatibility and sperm transfer in Drosophila simulans.

    Most insects harbour a variety of maternally inherited endosymbionts, the most widespread being Wolbachia pipientis that commonly induce cytoplasmic incompatibility (CI) and reduced hatching success in crosses between infected males and uninfected females. High temperature and increasing male age are known to reduce the level of CI in a variety of insects. In Drosophila simulans, infected males have been shown to mate at a higher rate than uninfected males. By examining the impact of mating rate independent of age, this study investigates whether a high mating rate confers an advantage to infected males through restoring their compatibility with uninfected females over and above the effect of age. The impact of Wolbachia infection, male mating rate and age on the number of sperm transferred to females during copulation and how it relates to CI expression was also assessed. As predicted, we found that reproductive compatibility was restored faster in males that mate at higher rate than that of low mating and virgin males, and that the effect of mating history was over and above the effect of male age. Nonvirgin infected males transferred fewer sperm than uninfected males during copulation, and mating at a high rate resulted in the transfer of fewer sperm per mating irrespective of infection status. These results indicate that the advantage to infected males of mating at a high rate is through restoration of reproductive compatibility with uninfected females, whereas uninfected males appear to trade off the number of sperm transferred per mating with female encounter rate and success in sperm competition. This study highlights the importance Wolbachia may play in sexual selection by affecting male reproductive strategies. © 2013 The Authors.

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

These proteins may comprise a network that regulates male sterility in wheat. Quantitative real time polymerase chain reaction (qRT-PCR analysis, ATP assays and total sugar assays validated the iTRAQ results. These DAPs could be associated with abnormal pollen grain formation and male sterility. Our findings provide insights into the molecular mechanism related to male sterility in wheat.

    Full Text Available Four cytoplasmic male sterile (cms F1flue-cured hybrids cv. Wiaelica × cv. Virginia Golta (VG, the male fertile analogue and the parental varieties were tested at two locations in Poland in a replicated field trial. The cms sources in the hybrids wereN. suaveolens,N. amplexicaulis,N. bigeloviiand aN. tabacumcms mutant. Under the slight to moderate pressure from black root rot present at the trial sites the hybrids showed a moderate tolerance of the disease characteristic of VG as opposed to medium strong susceptibility of Wislica. Apart from the effect of black root rot tolerance the vegetative vigor of the hybrids (plant height, leaf size, earliness was affected by cytoplasm source. The F1hybrid withN. suaveolens cytoplasm flowered approximately three days later than the remaining hybrids. Of the cms hybrids tested cmsN. bigelovii produced the tallest plants with largest mid-position leaves. Yields of cured leaves were largely influenced by black root rot and were generally higher in VG and in the hybrids than in Wislica. Leaf yields and curability were generally little affected by cms source under low pressure from black root rot. At the site with a relatively high level of black root rot infestation the yields of cmsN. suaveolens were slightly lower but the percentage of light grades slightly higher compared to those of other cms hybrids. CmsN. suaveolens was the best hybrid in terms of money returns at the low black root rot field but it was the poorest hybrid performer under high pressure from the disease. Contents of nitrogen, sugars, nicotine and ash was little affected by source of cms. There was an increased incidence of potato virus Y (PVY and white spots in cmsN. suaveolens and, to a lesser extent, in cmsN. bigelovii as compared to the remaining disease-free entries.

    A new non-heading Chinese cabbage CMS line M119A was characterized and specific molecular markers were developed to classify different CMS types. One new non-heading Chinese cabbage (Brassica rapa L.) cytoplasmic male sterile (CMS) line M119A was obtained by interspecific crosses between the recently discovered hau CMS line of Brassica juncea and B. rapa. Furthermore, the line was characterized and compared with other five isonuclear-alloplasmic CMS lines. The M119A line produced six stamens without pollen and only two stamen fused together in fewer flowers. Tissue section indicated that anther abortion in M119A may have occurred during differentiation of the archesporial cells without pollen sac. All the six CMS lines were grouped into three types based on the presence of three PCR fragments of 825, 465 and 772 bp amplified with different mitochondrial genes specific primers. The 825-bp fragment was amplified both in 09-10A and H201A using the specific primer pair P-orf224-atp6, and showed 100 % identity with the mitochondrial gene of pol CMS. The 465-bp fragment was amplified in 30A and 105A using the primer pair P-orf138 and shared 100 % identity with the mitochondrial gene of ogu CMS. The 772-bp fragment was amplified in M119A and H203A using the primer pair P-orf288 and showed 100 % identity with the mitochondrial gene of hau CMS. Therefore, these markers could efficiently distinguish different types of isonuclear-alloplasmic CMS lines of non-heading Chinese cabbage, which were useful for improving the efficiency of cross-breeding and heterosis utilization in cruciferous vegetables.

    To elucidate the metabolic mechanism of Ascorbic Acid (ASA) in the CMS-pepper anthers, the metabolism changes in the reactive oxygen species (ROS) contents, antioxidants contents and ROS scavenging enzymatic activities were investigated in the anther mitochondria of CMS-9704A and maintainer-9704B. At the abortion stage, anthers of CMS-9704A had higher contents of ROS than those of the maintainer. Simultaneously, there were lower contents of ASA and glutathione (GSH) in stage 2 and 3, and the lower activities of ascorbate peroxidase (APX) and glutathione perodixase (GPX) in stage 3 in scavenging ROS in the anthers of the CMS line than maintainer. The expression level of APX and GPX in stage 3 in anthers of CMS-9704A was obviously inhibited when ROS produced with a great deal during anther stage; however the gene expression kept normal in the maintainer. Excessive accumulation of ROS, significant reduction activities and gene expression level of ROS-scavenging enzyme were coinstantaneous with CMS. (author)

    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.

    Analysis of ISSR (Inter-Simple Sequence Repeat) and DDRT-PCR (Differential Display Reverse Transcriptase Polymerase Chain Reaction) was performed between cytoplasmic male sterility cauliflower ogura-A and its corresponding maintainer line ogura-B. Totally, 306 detectable bands were obtained by ISSR using thirty oligonucleotide primers. Commonly, six to twelve bands were produced per primer. Among all these primers only the amplification of primer ISSR3 was polymorphic, an 1100 bp specific band was only detected in maintainer line, named ISSR3(1100). Analysis of this sequence indicated that ISSR3(1100) was high homologous with the corresponding sequences of mitochondrial genome in Brassica napus and Arabidopsis thaliana,which suggested that ISSR3(1100) may derive from mitochondrial genome in cauliflower. To carry out DDRT-PCR analysis, three anchor primers and fifteen random primers were selected to combine. Totally, 1122 bands from 1 000 bp to 50 bp were detected. However, only four bands, named ogura-A 205, ogura-A383, ogura-B307 and ogura-B352, were confirmed to be different display in both lines. This result was further identified by reverse Northern dot blotting analysis. Among these four bands, ogura-A205 and ogura-A383 only express in cytoplasmic male sterility line, while ogura-B307 and ogura-B352 were only detected in maintainer line. Analysis of these sequences indicated that it was the first time that these four sequences were reported in cauliflower. Interestingly, ogura-A205 and ogura-B307 did not exhibit any similarities to other reported sequences in other species, more investigations were required to obtain further information. ogura-A383 and ogura-B352 were also two new sequences, they showed high similarities to corresponding chloroplast sequences of Arabidopsis thaliana and Brassica rapa subsp. pekinensis. So we speculated that these two sequences may derive from chloroplast genome. All these results obtained in this study offer new and

    The hybrid pigeonpea (Cajanus cajan) breeding technology based on cytoplasmic male sterility (CMS) is currently unique among legumes and displays major potential for yield increase. CMS is defined as a condition in which a plant is unable to produce functional pollen grains. The novel chimeric open reading frames (ORFs) produced as a results of mitochondrial genome rearrangements are considered to be the main cause of CMS. To identify these CMS-related ORFs in pigeonpea, we sequenced the mitochondrial genomes of three C. cajan lines (the male-sterile line ICPA 2039, the maintainer line ICPB 2039, and the hybrid line ICPH 2433) and of the wild relative (Cajanus cajanifolius ICPW 29). A single, circular-mapping molecule of length 545.7 kb was assembled and annotated for the ICPA 2039 line. Sequence annotation predicted 51 genes, including 34 protein-coding and 17 RNA genes. Comparison of the mitochondrial genomes from different Cajanus genotypes identified 31 ORFs, which differ between lines within which CMS is present or absent. Among these chimeric ORFs, 13 were identified by comparison of the related male-sterile and maintainer lines. These ORFs display features that are known to trigger CMS in other plant species and to represent the most promising candidates for CMS-related mitochondrial rearrangements in pigeonpea.

    Cytoplasmic male sterility (CMS) and nucleus-controlled fertility restoration are widespread plant reproductive features that provide useful tools to exploit heterosis in crops. However, the molecular mechanism underlying this kind of cytoplasmic-nuclear interaction remains unclear. Here, we show in rice (Oryza sativa) with Boro II cytoplasm that an abnormal mitochondrial open reading frame, orf79, is cotranscribed with a duplicated atp6 (B-atp6) gene and encodes a cytotoxic peptide. Expression of orf79 in CMS lines and transgenic rice plants caused gametophytic male sterility. Immunoblot analysis showed that the ORF79 protein accumulates specifically in microspores. Two fertility restorer genes, Rf1a and Rf1b, were identified at the classical locus Rf-1 as members of a multigene cluster that encode pentatricopeptide repeat proteins. RF1A and RF1B are both targeted to mitochondria and can restore male fertility by blocking ORF79 production via endonucleolytic cleavage (RF1A) or degradation (RF1B) of dicistronic B-atp6/orf79 mRNA. In the presence of both restorers, RF1A was epistatic over RF1B in the mRNA processing. We have also shown that RF1A plays an additional role in promoting the editing of atp6 mRNAs, independent of its cleavage function.

    Maize is one of the first crops to produce hybrids using cytoplasmic male sterile lines. The C-type cytoplasmic male sterile (CMS-C) line is vital for hybrid seed production, and the fertility-restoration reaction along with its stability has a direct bearing on its applications. However, fertility restoration mechanism of CMS-C is complex and is still not clear so far. To further explore the factors affecting the fertility restoration of maize CMS, a series of test crosses were carried out by pollinating the isocytoplasm allonuclear CMS-C lines C48-2, Chuangzaosi and C478 with the test lines 18 bai, zi 330, 5022 and the restorer line A619, respectively. Four F 2 populations and six double-cross combinations were obtained from the self-cross of fertility restored F 1 and pollinating male-sterility-maintained F 1 with the male-fertility-restored F 1 , respectively. Meanwhile, we developed the incomplete diallel-cross combinations using the isocytoplasm allonuclear male sterile lines as maternal parents and their respective maintainer lines 48-2, huangzaosi and 478 as paternal parents. All the F 1 , F 2 and double-cross populations were planted at distinct locations in different years, and the fertility-restoration reaction was scored by field investigation and pollen staining with I 2 -IK. The results were as follows: 1) The same test line could restore the CMS-C line at a certain genetic background, but failed to restore the CMS-C line at the other genetic backgrounds, suggesting that the genetic background of CMS-C lines plays an important role in the fertility restoration. 2) The fertile-to-sterile segregation ratio of (C48-2×A619) F 2 population planted in both Sichuan and Yunnan fited well to 15:1 by the χ 2 test. However, the fertility level of individuals in Yunnan mainly belonged to the 3 and 4grades, but which in Sichuan mainly belonged to the 5 grade, indicating the environmental factors had effect on the fertility-restoration reaction of (C48-2×A619) F

    Tritium-labeled toxin analogs were prepared by reduction with NaB 3 H 4 of either the toxin from Helminthosporium maydis race T or a toxin component from Phyllosticta maydis. These reduced analogs had high radiochemical specific activities, high biological activities, and plant specificities identical to the native toxins. A filtration assay was developed to test the binding of these labeled analogs to isolated mitochondria. Binding was not energy dependent nor was there measurable matrical uptake. The analogs were shown to be lipophilic, a characteristic which gave rise to considerable nondisplaceable binding. Under conditions limiting nondisplaceable binding, the displaceable binding was shown to be linear with respect to toxin concentration and unsaturable. No significant differences were observed in the binding characteristics between the mitochondria from normal and male-sterile (Texas) cytoplasm maize. The findings suggest that, at physiologically relevant concentrations, these toxin analogs permeate the membranes of susceptible and resistant mitochondria alike. The lack of demonstrable specific binding does not rule out the involvement of a classical receptor site but does indicate that other kinds of molecular interactions may be involved in the mechanisms for toxicity and specificity

    A novel cytoplasmic male sterility (CMS) in Brassica napus (inap CMS) was selected from the somatic hybrid with Isatis indigotica (Chinese woad) by recurrent backcrossing. The male sterility was caused by the conversion of tetradynamous stamens into carpelloid structures with stigmatoid tissues at their tips and ovule-like tissues in the margins, and the two shorter stamens into filaments without anthers. The feminized development of the stamens resulted in the complete lack of pollen grains, which was stable in different years and environments. The pistils of inap CMS displayed normal morphology and good seed-set after pollinated by B. napus . Histological sections showed that the developmental alteration of the stamens initiated at the stage of stamen primordium differentiation. AFLP analysis of the nuclear genomic composition with 23 pairs of selective primers detected no woad DNA bands in inap CMS. Twenty out of 25 mitochondrial genes originated from I. indigotica , except for cox2-2 which was the recombinant between cox2 from woad and cox2-2 from rapeseed. The novel cox2-2 was transcribed in flower buds of inap CMS weakly and comparatively with the fertile B. napus addition line Me harboring one particular woad chromosome. The restorers of other autoplasmic and alloplasmic CMS systems in rapeseed failed to restore the fertility of inap CMS and the screening of B. napus wide resources found no fertility restoration variety, showing its distinct origin and the related mechanism of sterility. The reasons for the mitochondrial rearrangements and the breeding of the restorer for the novel CMS system were discussed.

    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. 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. The complete mitochondrial genome of the wheat K-type CMS line Ks3 is very different from that of its maintainer line Km3, especially in non

    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

    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.

    Cytoplasmic male sterility (CMS) and nucleus-controlled fertility restoration are widespread plant reproductive features that provide useful tools to exploit heterosis in crops. However, the molecular mechanism underlying this kind of cytoplasmic–nuclear interaction remains unclear. Here, we show in rice (Oryza sativa) with Boro II cytoplasm that an abnormal mitochondrial open reading frame, orf79, is cotranscribed with a duplicated atp6 (B-atp6) gene and encodes a cytotoxic peptide. Expression of orf79 in CMS lines and transgenic rice plants caused gametophytic male sterility. Immunoblot analysis showed that the ORF79 protein accumulates specifically in microspores. Two fertility restorer genes, Rf1a and Rf1b, were identified at the classical locus Rf-1 as members of a multigene cluster that encode pentatricopeptide repeat proteins. RF1A and RF1B are both targeted to mitochondria and can restore male fertility by blocking ORF79 production via endonucleolytic cleavage (RF1A) or degradation (RF1B) of dicistronic B-atp6/orf79 mRNA. In the presence of both restorers, RF1A was epistatic over RF1B in the mRNA processing. We have also shown that RF1A plays an additional role in promoting the editing of atp6 mRNAs, independent of its cleavage function. PMID:16489123

    Full Text Available 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

    Alterations of mitochondrial-encoded subunits of the F(o)F(1)-ATP synthase are frequently associated with cytoplasmic male sterility (CMS) in plants; however, little is known about the relationship of the nuclear encoded subunits of this enzyme with CMS. In the present study, the full cDNA of the gene TaF(A)d that encodes the putative F(A)d subunit of the F(o)F(1)-ATP synthase was isolated from the wheat (Triticum aestivum) fertility restorer '2114' for timopheevii cytoplasm-based CMS. The deduced 238 amino acid polypeptide is highly similar to its counterparts in dicots and other monocots but has low homology to its mammalian equivalents. TaF(A)d is a single copy gene in wheat and maps to the short arm of the group 6 chromosomes. Transient expression of the TaF(A)d-GFP fusion in onion epidermal cells demonstrated TaF(A)d's mitochondrial location. TaF(A)d was expressed abundantly in stem, leaf, anther, and ovary tissues of 2114. Nevertheless, its expression was repressed in anthers of CMS plants with timopheevii cytoplasm. Genic male sterility did not affect its expression in anthers. The expression of the nuclear gene encoding the 20 kDa subunit of F(o) was down-regulated in a manner similar to TaF(A)d in the T-CMS anthers while that of genes encoding the 6 kDa subunit of F(o) and the gamma subunit of F(1) was unaffected. These observations implied that TaF(A)d is under mitochondrial retrograde regulation in the anthers of CMS plants with timopheevii cytoplasm.

    Full Text Available 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 Yuetai A mainly resulted from the genetic drift of restoring fertility gene (Rf 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%.

    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

    The transcriptional patterns of mitochondrial respiratory related genes were investigated in cytoplasmic male-sterile and fertile maintainer lines of stem mustard, Brassica juncea. There were numerous differences in nad2 (subunit 2 of NADH dehydrogenase) between stem mustard CMS and its maintainer line. One novel open reading frame, hereafter named orfB gene, was located at the downstream of mitochondrial nad2 gene in the CMS. The novel orfB gene had high similarity with YMF19 family protein, orfB in Raphanus sativus, Helianthus annuus, Nicotiana tabacum and Beta vulgaris, orfB-CMS in Daucus carota, atp8 gene in Arabidopsis thaliana, 5' flanking of orf224 in B. napus (nap CMS) and 5' flanking of orf220 gene in CMS Brassica juncea. Three copies probed by specific fragment (amplified by primers of nad2F and nad2R from CMS) were found in the CMS line following Southern blotting digested with HindIII, but only a single copy in its maintainer line. Meanwhile, two transcripts were shown in the CMS line following Northern blotting while only one transcript was detected in the maintainer line, which were probed by specific fragment (amplified by primers of nad2F and nad2R from CMS). Meanwhile, the expression of nad2 gene was reduced in CMS bud compared to that in its maintainer line. We thus suggested that nad2 gene may be co-transcripted with CMS-associated orfB gene in the CMS. In addition, the specific fragment that was amplified by primers of nad2F and nad2R just spanned partial sequences of nad2 gene and orfB gene. Such alterations in the nad2 gene would impact the activity of NADH dehydrogenase, and subsequently signaling, inducing the expression of nuclear genes involved in male sterility in this type of cytoplasmic male sterility.

    Full Text Available Wheat (Triticum aestivum L. is a major crop worldwide. The utilization of heterosis is a promising approach to improve the yield and quality of wheat. Although there have been many studies on wheat cytoplasmic male sterility, its mechanism remains unclear. In this study, we identified two MADS-box genes from a wheat K-type cytoplasmic male sterile (CMS line using homology-based cloning. These genes were localized on wheat chromosomes 3A and 3B and named TaAG-A and TaAG-B, respectively. Analysis of TaAG-A and TaAG-B expression patterns in leaves, spikes, roots, and stems of Chinese Spring wheat determined using quantitative RT-PCR revealed different expression levels in different tissues. TaAG-A had relatively high expression levels in leaves and spikes, but low levels in roots, while TaAG-B had relatively high expression levels in spikes and lower expression in roots, stems, and leaves. Both genes showed downregulation during the mononucleate to trinucleate stages of pollen development in the maintainer line. In contrast, upregulation of TaAG-B was observed in the CMS line. The transcript levels of the two genes were clearly higher in the CMS line compared to the maintainer line at the trinucleate stage. Overexpression of TaAG-A and TaAG-B in Arabidopsis resulted in phenotypes with earlier reproductive development, premature mortality, and abnormal buds, stamens, and stigmas. Overexpression of TaAG-A and TaAG-B gives rise to mutants with many deformities. Silencing TaAG-A and TaAG-B in a fertile wheat line using the virus-induced gene silencing (VIGS method resulted in plants with green and yellow striped leaves, emaciated spikes, and decreased selfing seed set rates. These results demonstrate that TaAG-A and TaAG-B may play a role in male sterility in the wheat CMS line.

  16. Abortion: a history.

    1985-01-01

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

  18. Identification of Genes Potentially Associated with the Fertility Instability of S-Type Cytoplasmic Male Sterility in Maize via Bulked Segregant RNA-Seq.

    Directory of Open Access Journals (Sweden)

    Aiguo Su

    Full Text Available S-type cytoplasmic male sterility (CMS-S is the largest group among the three major types of CMS in maize. CMS-S exhibits fertility instability as a partial fertility restoration in a specific nuclear genetic background, which impedes its commercial application in hybrid breeding programs. The fertility instability phenomenon of CMS-S is controlled by several minor quantitative trait locus (QTLs, but not the major nuclear fertility restorer (Rf3. However, the gene mapping of these minor QTLs and the molecular mechanism of the genetic modifications are still unclear. Using completely sterile and partially rescued plants of fertility instable line (FIL-B, we performed bulk segregant RNA-Seq and identified six potential associated genes in minor effect QTLs contributing to fertility instability. Analyses demonstrate that these potential associated genes may be involved in biological processes, such as floral organ differentiation and development regulation, energy metabolism and carbohydrates biosynthesis, which results in a partial anther exsertion and pollen fertility restoration in the partially rescued plants. The single nucleotide polymorphisms (SNPs identified in two potential associated genes were validated to be related to the fertility restoration phenotype by KASP marker assays. This novel knowledge contributes to the understanding of the molecular mechanism of the partial fertility restoration of CMS-S in maize and thus helps to guide the breeding programs.

    The expression of the protamines, the predominant nuclear proteins of mammalian spermatozoa, is regulated translationally during male germ-cell development. The 3' untranslated region (UTR) of protamine 1 mRNA has been reported to control its time of translation. To understand the mechanisms controlling translation of the protamine mRNAs, we have sought to identify cis elements of the 3' UTR of protamine 2 mRNA that are recognized by cytoplasmic factors. From gel retardation assays, two sequence elements are shown to form specific RNA-protein complexes. Protein binding sites of the two complexes were determined by RNase T1 mapping, by blocking the putative binding sites with antisense oligonucleotides, and by competition assays. The sequences of these elements, located between nucleotides + 537 and + 572 in protamine 2 mRNA, are highly conserved among postmeiotic translationally regulated nuclear proteins of the mammalian testis. Two closely linked protein binding sites were detected. UV-crosslinking studies revealed that a protein of about 18 kDa binds to one of the conserved sequences. These data demonstrate specific protein binding to a highly conserved 3' UTR of translationally regulated testicular mRNA

    Full Text Available Abstract Background Plant mitochondrial genomes are known for their complexity, and there is abundant evidence demonstrating that this organelle is important for plant sexual reproduction. Cytoplasmic male sterility (CMS is a phenomenon caused by incompatibility between the nucleus and mitochondria that has been discovered in various plant species. As the exact sequence of steps leading to CMS has not yet been revealed, efforts should be made to elucidate the factors underlying the mechanism of this important trait for crop breeding. Results Two CMS mitochondrial genomes, LD-CMS, derived from Oryza sativa L. ssp. indica (434,735 bp, and CW-CMS, derived from Oryza rufipogon Griff. (559,045 bp, were newly sequenced in this study. Compared to the previously sequenced Nipponbare (Oryza sativa L. ssp. japonica mitochondrial genome, the presence of 54 out of 56 protein-encoding genes (including pseudo-genes, 22 tRNA genes (including pseudo-tRNAs, and three rRNA genes was conserved. Two other genes were not present in the CW-CMS mitochondrial genome, and one of them was present as part of the newly identified chimeric ORF, CW-orf307. At least 12 genomic recombination events were predicted between the LD-CMS mitochondrial genome and Nipponbare, and 15 between the CW-CMS genome and Nipponbare, and novel genetic structures were formed by these genomic rearrangements in the two CMS lines. At least one of the genomic rearrangements was completely unique to each CMS line and not present in 69 rice cultivars or 9 accessions of O. rufipogon. Conclusion Our results demonstrate novel mitochondrial genomic rearrangements that are unique in CMS cytoplasm, and one of the genes that is unique in the CW mitochondrial genome, CW-orf307, appeared to be the candidate most likely responsible for the CW-CMS event. Genomic rearrangements were dynamic in the CMS lines in comparison with those of rice cultivars, suggesting that 'death' and possible 'birth' processes of the

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

    Three-line Oryza sativa (ssp. japonica) hybrids have been developed mainly using Chinsurah Boro II (BT)-type cytoplasmic male sterility (CMS). The Rf1 gene restores the fertility of BT-type CMS lines, and is the only fertility restorer gene (Rf) that has been used to produce three-line japonica hybrids. Using more Rf genes to breed BT-type restorer lines may broaden the genetic diversity of the restorer lines, and represents a viable approach to improve the heterosis level of BT-type japonica hybrids. We identified two major Rf genes from '93-11' that are involved in restoring the fertility of BT-type CMS plants. These genes were identified from resequenced chromosome segment substitution lines derived from a cross between the japonica variety 'Nipponbare' and the indica variety '93-11'. Molecular mapping results revealed that these genes were Rf5 and Rf6, which are the Rf genes that restore fertility to Honglian-type CMS lines. The BT-type F 1 hybrids with either Rf5 or Rf6 exhibited normal seed setting rates, but F 1 plants carrying Rf6 showed more stable seed setting rates than those of plants carrying Rf5 under heat-stress conditions. Furthermore, the seed setting rates of F 1 hybrids carrying both Rf5 and Rf6 were more stable than that of F 1 plants carrying only one Rf gene. Rf6 is an important genetic resource for the breeding of BT-type japonica restorer lines. Our findings may be useful for breeders interested in developing BT-type japonica hybrids.

    Full Text Available Anomalous left coronary artery arising from the pulmonary artery (ALCAPA is a rare type of congenital coronary abnormality that may be associated with early infant mortality and sudden adult cardiac death. We report a case regarding a 23-year-old male who collapsed during a marathon race and was resuscitated with cardiopulmonary resuscitation. Subsequent workups verified the diagnosis of ALCAPA. The patient underwent surgical intervention with obliteration of the ALCAPA orifice and coronary artery bypass grafting with left internal mammary artery to left anterior descending coronary artery. The procedure was done smoothly, and he was discharged uneventfully.

  5. Abortion ethics.

    Fromer, M J

    1982-04-01

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

    Iso-cytoplasmic restorers possess the same male sterile cytoplasm as the cytoplasmic male sterile (CMS) lines, thereby minimizing the potential cyto-nuclear conflict in the hybrids. Restoration of fertility of the wild abortive CMS is governed by two major genes namely, Rf3 and Rf4 . Therefore, assessing the allelic status of these restorer genes in the iso-cytoplasmic restorers using molecular markers will not only help in estimating the efficiency of these genes either alone or in combination, in fertility restoration in the hybrids in different environments, but will also be useful in determining the efficacy of these markers. In the present study, the efficiency of molecular markers in identifying genotypes carrying restorer allele of the gene(s) Rf3 and Rf4, restoring male fertility of WA cytoplasm in rice was assessed in a set of 100 iso-cytoplasmic rice restorers using gene linked as well as candidate gene based markers. In order to validate the efficacy of markers in identifying the restorers, a sub-set of selected 25 iso-cytoplasmic rice restorers were crossed with four different cytoplasmic male sterile lines namely, IR 79156A, IR 58025A, Pusa 6A and RTN 12A, and the pollen and spikelet fertility of the F 1 s were evaluated at three different locations. Marker analysis showed that Rf4 was the predominant fertility restorer gene in the iso-cytoplasmic restorers and Rf3 had a synergistic effect on fertility restoration. The efficiency of gene based markers, DRCG-RF4-14 and DRRM-RF3-10 for Rf4 (87%) and Rf3 (84%) genes was higher than respective gene-linked SSR markers RM6100 (80%) and RM3873 (82%). It is concluded that the gene based markers can be effectively used in identifying fertility restorer lines obviating the need for making crosses and evaluating the F 1 s. Though gene based markers are more efficient, there is a need to identify functional polymorphisms which can provide 100% efficiency. Three iso-cytoplasmic restorers namely, PRR 300, PRR 363

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

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

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

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

    Cytoplasmic male sterility (CMS) is not only important for exploiting heterosis in crop plants, but also as a model for investigating nuclear-cytoplasmic interaction. CMS may be caused by mutations, rearrangement or recombination in the mitochondrial genome. Understanding the mitochondrial genome is often the first and key step in unraveling the molecular and genetic basis of CMS in plants. Comparative analysis of the mitochondrial genome of the hau CMS line and its maintainer line in B. juneca (Brassica juncea) may help show the origin of the CMS-associated gene orf288. Through next-generation sequencing, the B. juncea hau CMS mitochondrial genome was assembled into a single, circular-mapping molecule that is 247,903 bp in size and 45.08% in GC content. In addition to the CMS associated gene orf288, the genome contains 35 protein-encoding genes, 3 rRNAs, 25 tRNA genes and 29 ORFs of unknown function. The mitochondrial genome sizes of the maintainer line and another normal type line "J163-4" are both 219,863 bp and with GC content at 45.23%. The maintainer line has 36 genes with protein products, 3 rRNAs, 22 tRNA genes and 31 unidentified ORFs. Comparative analysis the mitochondrial genomes of the hau CMS line and its maintainer line allowed us to develop specific markers to separate the two lines at the seedling stage. We also confirmed that different mitotypes coexist substoichiometrically in hau CMS lines and its maintainer lines in B. juncea. The number of repeats larger than 100 bp in the hau CMS line (16 repeats) are nearly twice of those found in the maintainer line (9 repeats). Phylogenetic analysis of the CMS-associated gene orf288 and four other homologous sequences in Brassicaceae show that orf288 was clearly different from orf263 in Brassica tournefortii despite of strong similarity. The hau CMS mitochondrial genome was highly rearranged when compared with its iso-nuclear maintainer line mitochondrial genome. This study may be useful for studying the

  15. Breeding and characterization of homokaryotic heteroplasmic male sterile lines in rice (oryza sativa)

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

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

    Genotyping by sequencing (GBS) is an efficient method of genotyping in numerous plant species. One of the crucial steps toward the application of GBS markers in crop improvement is anchoring them on particular chromosomes. In rye (Secale cereale L.), chromosomal localization of GBS markers has not yet been reported. In this paper, the application of GBS markers generated by the DArTseq platform for extending the high-density map of rye is presented. Additionally, their application is used for the localization of the Rfc1 gene that restores male fertility in plants with the C source of sterility-inducing cytoplasm. The total number of markers anchored on the current version of the map is 19,081, of which 18,132 were obtained from the DArTseq platform. Numerous markers co-segregated within the studied mapping population, so, finally, only 3397 unique positions were located on the map of all seven rye chromosomes. The total length of the map is 1593 cM and the average distance between markers is 0.47 cM. In spite of the resolution of the map being not very high, it should be a useful tool for further studies of the Secale cereale genome because of the presence on this map of numerous GBS markers anchored for the first time on rye chromosomes. The Rfc1 gene was located on high-density maps of the long arm of the 4R chromosome obtained for two mapping populations. Genetic maps were composed of DArT, DArTseq, and PCR-based markers. Consistent mapping results were obtained and DArTs tightly linked to the Rfc1 gene were successfully applied for the development of six new PCR-based markers useful in marker-assisted selection.

  1. Trying to prevent abortion.

    1997-06-01

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

    Science.gov (United States)

    Lalli, Chiara

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

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

    Specific immunochemical probes for Z-RNA were generated and characterized to search for possible Z-RNA-like double helices in cells. Z-RNA was detected in the cytoplasm of fixed protozoan cells by immunofluorescence microscopy using these anti-Z-RNA IgCs. In contrast, autoimmune or experimentally elicited anti-DNA antibodies, specifically reactive with B-DNA or Z-DNA, stained the nuclei. Pre-or nonimmune IgGs did not bind to the cells. RNase A or T1 digestion eliminated anti-Z-RNA IgG binding to cytoplasmic determinants; however, DNase I or mung bean nuclease had no effect. Doxorubicin and ethidium bromide prevented anti-Z-RNA antibody binding; however, actinomycin D, which does not bind double-stranded RNA, did not. Anti-Z-RNA immunofluorescence was specifically blocked in competition assays by synthetic Z-RNA but not Z-DNA, A-RNA, or single-stranded RNAs. Thus, some cytoplasmic sequences in fixed cells exist in the left-handed Z-RNA conformation

    Rice restorer lines were treated with 60 Co 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 F 1 spikelets were normal and fertile, and different numbers of male sterile plants were segregated in F 2 . Complete fertility genotype was not found among interactions between induced male sterile genes and alien-cytoplasms. (authors)

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

  7. [Bioethics and abortion. Debate].

    Diniz, D; Gonzalez Velez, A C

    1998-06-01

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

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

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

Seed set upon open-pollination of the male sterile plants with the variety PR 106 ranged from 0.03 to 4.93 per cent whereas no seed formed in bagged panicles. In M{sub 3}, open-pollinated progenies of the male sterile plants and their fertile sibs were further studied. Two progenies segregated for male sterility, all others had only fertile plants. In one of the segregating progenies, five out of six and in the other nine out of fourteen plants were male sterile. The progenies of fertile sibs did not have any male sterile plant. The results indicate that sterility of cytoplasmic type has been induced by EMS. The parental variety PR 106 acts as the maintainer. (author)

    1994-03-01

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

    1967-10-01

    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.

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

  20. Post abortion syndrome?

    Science.gov (United States)

    1987-12-01

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

  1. The incidence of abortion worldwide.

    1999-01-01

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

  2. Catholic attitudes toward abortion.

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

  3. The Stratified Legitimacy of Abortions.

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

  4. Unsafe abortion: the silent scourge.

    Grimes, David A

    2003-01-01

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

  5. On the Wrongfulness of abortion

    2017-07-01

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

    In 2010, following its approval by the Ministry of Health, the medical abortion combination pack Medabon (containing mifepristone and misoprostol) was made available at pharmacies and in a restricted number of health facilities in Cambodia. The qualitative study presented in this paper was conducted in 2012 as a follow-up to longer-term ethnographical research related to reproductive health and fertility regulation between 2008 and 2012. Observations were carried out at several clinic and pharmacy sites and in-depth interviews were conducted with a purposive sample of 20 women who attended two MSI Cambodia centres and 10 women identified through social networks; six men (women's male partners); eight health care providers at the two MSI centres and four pill sellers at private or informal pharmacies (who also provided health care services in private clinics). Although the level of training among the drug sellers and providers varied, their knowledge about medical abortion regimens, correct usage and common side effects was good. Overall, women were satisfied with the services provided. Medical abortion was not always a women-only process in this study as some male partners were also involved in the care process. The study illustrates positive steps forward being taken in making abortion safe and preventing and reducing unsafe abortion practices in Cambodia. Copyright © 2015 Reproductive Health Matters.

  7. Late induced abortion.

    Science.gov (United States)

    Savage, W

    1990-09-01

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

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

    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.

  9. [Abortion: towards worldwide legalization].

    Science.gov (United States)

    1998-09-01

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

  10. Jewish views on abortion.

    Science.gov (United States)

    Jakobovits, I

    1968-01-01

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

  11. Defining minors' abortion rights.

    Science.gov (United States)

    Rhodes, A M

    1988-01-01

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

    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.

    2011-01-01

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

    Science.gov (United States)

    Misago, C

    1994-12-01

    The continued illegality of induced abortion in Latin America has led to substantial, preventable maternal mortality and morbidity. The first strategy for preventing unsafe clandestine abortion is to reduce the incidence of unwanted pregnancy through measures such as improved access to effective contraception, post-abortion family planning counseling, health education campaigns aimed at promoting condom use among young people, involvement of men in family planning decision making, biomedical research on safer and more effective male and female contraceptive methods, and empowering women to demand the use of condoms or avoid unwanted intercourse. The second strategy is to reduce abortion-related mortality and morbidity through more effective clinical management of incomplete illegal abortions, introduction of menstrual regulation services, formation of women's solidarity groups aimed at discouraging the practice of self-induced abortion, and, ultimately, abortion legalization.

    Social manifestations of abortion stigma depend upon cultural, legal, and religious context. Abortion stigma in Mexico is under-researched. This study explored the sources, experiences, and consequences of stigma from the perspectives of women who had had an abortion, male partners, and members of the general population in different regional and legal contexts. We explored abortion stigma in Mexico City where abortion is legal in the first trimester and five states-Chihuahua, Chiapas, Jalisco, Oaxaca, and Yucatán-where abortion remains restricted. In each state, we conducted three focus groups-men ages 24-40 years (n = 36), women 25-40 years (n = 37), and young women ages 18-24 years (n = 27)-and four in-depth face-to-face interviews in total; two with women (n = 12) and two with the male partners of women who had had an abortion (n = 12). For 4 of the 12 women, this was their second abortion. This exploratory study suggests that abortion stigma was influenced by norms that placed a high value on motherhood and a conservative Catholic discourse. Some participants in this study described abortion as an "indelible mark" on a woman's identity and "divine punishment" as a consequence. Perspectives encountered in Mexico City often differed from the conservative postures in the states.

    To evaluate the representation of abortion in contemporary hip-hop music, gaining insight into the myriad of attitudes of abortion in the black community. We used Genius, an online storehouse for lyrical content, to identify songs by querying the database for search terms related to family planning, including slang terms. We then cross-referenced identified songs using an online list of songs about abortion. We analyzed eligible songs using grounded theory in order to identify key themes. Of 6577 songs available, a total of 101 songs performed by 122 individual artists met inclusion criteria. The majority of artists were Black men; five artists were Black women. Key themes were: use of abortion as braggadocio; equating abortion with sin, genocide, or murder; male pressure for women to seek abortion; and the specific association of Planned Parenthood services with abortion. The moral and ethical themes surrounding abortion in hip-hop lyrics reveal a unique perspective within a marginalized community. The overall negative context of abortion in hip-hop lyrics needs to be reconciled with the gendered, economic, historical, political, racial and ethnic background of hip-hop and rap music in America. This study is the first to evaluate lyrical content from contemporary popular music in relation to abortion and family planning. Examining the intersection of reproductive rights and popular culture can provide a unique insight into the limited knowledge of the perspectives of abortion in the black community.

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

  8. The politicization of abortion and the evolution of abortion counseling.

    2013-01-01

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

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

    1997-01-01

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

It is unusual for the antineutrophil cytoplasmic antibody with cytoplasmic pattern (cANCA to present in patients with inflammatory bowel disease (IBD without vasculitis. The purpose of this study was to describe the occurrence and characteristics of pediatrics IBD with cANCA. Methods. A retrospective review of pediatric IBD associated with cANCA serology in patients from King Abdulaziz University Hospital, Saudi Arabia, between September 2002 and February 2012. Results. Out of 131 patients with IBD screened for cANCAs, cANCA was positive in 7 (5.3% patients of whom 4 had ulcerative colitis and 3 had Crohn's disease. The median age was 8.8 years (2–14.8 years. Six (86% were males. Of the 7 patients, 5 (71% were Saudi Arabians and 2 were of Indian ethnicity. The most common symptoms were diarrhea, abdominal pain, weight loss, and rectal bleeding. None had family history or clinical features suggestive of vasculitis involving renal and respiratory systems. No difference in the disease location or severity was observed between cANCA positive and cANCA negative patients apart from male preponderance in cANCA positive patients. Conclusion. The occurrence of cANCA in pediatric IBD is rare. Apart from male preponderance, there were no peculiar characteristics for the cANCA positive patients.

  13. Crime, Teenage Abortion, and Unwantedness

    Shoesmith, Gary L.

    2015-01-01

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

  14. Abortion in a just society.

    Science.gov (United States)

    Hunt, M E

    1993-01-01

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

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

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

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

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

  18. Psychiatric sequelae of induced abortion.

    1984-03-01

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

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

  20. Psychosocial aspects of induced abortion.

    1997-09-01

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

The data were analyzed using the thematic analysis technique, and, subsequently, by the IBM SPSS Statistics Standard Edition software program. The significance level was set at p women who induced an abortion referred to the partner as the person who could not find out about the abortion (pindependence, women still regard male participation in the abortion process as an important factor. The specifics of each capital denote the influence of the geographic and cultural dimension, indicating the need to take into account the particulars of each region in Brazil while considering a holistic approach to women's health.

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

  3. Mental health consequences of abortion and refused abortion.

    1980-02-01

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

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

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

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

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

    1979-08-01

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

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

    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.

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

    Henshaw, S K

    1987-01-01

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

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

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

  17. Abortion in Croatia and Slovenia.

    Science.gov (United States)

    1992-01-01

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

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

    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

  20. Mechanisms for cytoplasmic organization: an overview.

    One of the basic characteristics of life is the intrinsic organization of cytoplasm, yet we know surprisingly little about the manner in which cytoplasmic macromolecules are arranged. It is clear that cytoplasm is not the homogeneous "soup" it was once envisioned to be, but a comprehensive model for cytoplasmic organization is not available in modern cell biology. The premise of this volume is that phase separation in cytoplasm may play a role in organization at the subcellular level. Other mechanisms for non-membrane-bounded intracellular organization have previously been proposed. Some of these will be reviewed in this chapter. Multiple mechanisms, involving phase separation, specific intracellular targeting, formation of macromolecular complexes, and channeling, all could well contribute to cytoplasmic organization. Temporal and spatial organization, as well as composition, are likely to be important in defining the characteristics of cytoplasm.

  1. Youth often risk unsafe abortions.

    Science.gov (United States)

    Barnett, B

    1993-10-01

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

  2. TEN RILLINGTON PLACE AND THE CHANGING POLITICS OF ABORTION IN MODERN BRITAIN.

    Science.gov (United States)

    Jones, Emma L; Pemberton, Neil

    2014-12-01

    This article addresses the social, cultural, and political history of backstreet abortion in post-war Britain, focusing on the murders of Beryl Evans and her daughter Geraldine, at Ten Rillington Place in 1949. It shows how the commonplace connection of John Christie to abortion and Beryl Evan's death was not a given in the wider public, legal, political, and forensic imagination of the time, reflecting the multi-layered and shifting meanings of abortion from the date of the original trials in the late 1940s and 1950s, through the subsequent judicial and literary reinvestigations of the case in the 1960s, to its cinematic interpretation in the 1970s. Exploring the language of abortion used in these different contexts, the article reveals changes in the gendering of abortionists, the increasing power and presence of abortion activists and other social reformers, the changing representation of working-class women and men, and the increasing critique of the practice of backstreet abortion. The case is also made for a kind of societal blind spot on abortion at the time of both the Evans and Christie trials; in particular, a reluctance to come to terms with the concept of the male abortionist, which distorted the criminal investigations and the trials themselves. Only when public acceptance for legalizing abortion grew in the more liberal climate of the 1960s and beyond did a revisionist understanding of the murder of Beryl Evans, in which abortion came to be positioned as a central element, gain a sustained hearing.

  3. [Psychological aspects of induced abortion].

    1982-06-01

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

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

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

    Science.gov (United States)

    1993-10-05

    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.

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

  8. New German abortion law agreed.

    1995-07-15

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

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

    1989-12-01

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

    2018-03-01

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

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

  15. Psychiatric aspects of induced abortion.

    Science.gov (United States)

    Stotland, Nada L

    2011-08-01

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

    2014-08-01

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

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

    Hursthouse, Rosalind

    1991-01-01

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

  20. Abortion - a philosophical perspective

    Directory of Open Access Journals (Sweden)

    MN Jali

    2001-09-01

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

  1. Late Abortion: A Comprehensive Review

    Directory of Open Access Journals (Sweden)

    Sheng Chiang

    2005-12-01

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

    To understand beliefs about unintended pregnancy and abortion, and perceptions about male roles related to pregnancy decision-making among men in the Philippines. Qualitative data were collected during in-depth interviews and focus group discussions with men in an urban area of the Philippines between October 2007 and July 2008. Interview participants were purposively sampled from a local survey based on their having reported being "afraid or troubled" or "afraid and planned to terminate" in response to a recent pregnancy. Focus group participants were selected from the same communities. Data were analyzed using the constant comparative method. In-depth interview data from 15 men-each interviewed twice-and five focus group discussions were included. Male interview participants reported feeling morally responsible for the pregnancy and as wanting to avoid the "sin" of induced abortion; however, they were concerned about being able to support a family financially. Participants expressed resentment towards partners who attempted or completed an induced abortion without their knowledge. In such cases, men would disparage their partner and cease interacting with them to avoid the "sin" of induced abortion. Participants described negative feelings towards women seeking induced abortions, and their own desire to avoid associated "sin". This highlights the effects of unintended pregnancy and induced abortion on young Filipino men, including their own experience of abortion stigma. © 2017 International Federation of Gynecology and Obstetrics.

Experiment ED-63 was to observe the effect of zero-gravity on cytoplasmic streaming in the aquatic plant named Elodea, commonly called water weed or water thyme. The phenomenon of cytoplasmic streaming is not well understood, but it is recognized as the circulation mechanism of the internal materials or cytoplasm of a cell. Cytoplasm is a gelatinous substance that has the ability to change its viscosity and flow, carrying various cell materials with it. The activity can be stimulated by sunlight or heat. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab.

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

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.

    Cytoplasmic streaming is a type of intracellular transport widely seen in nature. Cytoplasmic streaming in Caenorhabditis elegans at the one-cell stage is bidirectional; the flow near the cortex (“cortical flow”) is oriented toward the anterior, whereas the flow in the central region (“cytoplasmic flow”) is oriented toward the posterior. Both cortical flow and cytoplasmic flow depend on non-muscle-myosin II (NMY-2), which primarily localizes in the cortex. The manner in which NMY-2 proteins drive cytoplasmic flow in the opposite direction from remote locations has not been fully understood. In this study, we demonstrated that the hydrodynamic properties of the cytoplasm are sufficient to mediate the forces generated by the cortical myosin to drive bidirectional streaming throughout the cytoplasm. We quantified the flow velocities of cytoplasmic streaming using particle image velocimetry (PIV) and conducted a three-dimensional hydrodynamic simulation using the moving particle semiimplicit method. Our simulation quantitatively reconstructed the quantified flow velocity distribution resolved through PIV analysis. Furthermore, our PIV analyses detected microtubule-dependent flows during the pronuclear migration stage. These flows were reproduced via hydrodynamic interactions between moving pronuclei and the cytoplasm. The agreement of flow dynamics in vivo and in simulation indicates that the hydrodynamic properties of the cytoplasm are sufficient to mediate cytoplasmic streaming in C. elegans embryos.

    Discussing the abortion theme in Brazil is highly problematic since it involves ethical, moral and legal precepts. The criminalization of abortion in Brazil favors a clandestine and unsafe practice and can lead to serious consequences to women´s health. In this perspective, this research deals with the legal context in which the abortion problem is inscribed in Brazil, coupled to the specific aims in pinpointing complications caused by the criminalization of clandestine abortion besides deali...

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

  11. Abortion research: attitudes, sexual behavior, and problems in a community college population.

    1993-02-01

    150 (80 females and 70 males) community college students were surveyed regarding their attitudes toward abortion, their sexual behavior, and their problems. The profile of the students was Caucasian (95%), young (18-24 years = 87%), single (87%), middle and lower middle class, and Catholic (70%). 82% supported abortion choice, 86% had engaged in premarital sex, 70% used contraception, and 26% had premarital pregnancies. The hard reasons for abortion (rape, the woman's life, is endangered, and the fetus is defective) received high support. The soft reasons (the family cannot afford more children or the woman does not want to marry the man) received lower support. The students were divided into 3 groups of 50 students based on the number of abortion reasons they supported out of 43 reasons. The low-group that accepted 0-10 reasons was called anti-abortion. 50% of them still believed a woman has a right to an abortion vs. 97% of the pro-abortion students. The students reported many problems in their families: alcoholic home (39%), loss of a parent through death, divorce, or separation (33%), victims of severe corporal punishment (31%), one or more family members physically abused (20%), and deprived of parental affection while growing up (20%). When the anti-abortion females (N=30) were compared with the pro-abortion females (N=50), they reported significantly (p.01) more hospitalization, a greater number of physical handicaps, and more shyness (p.1). When the anti-abortion males (N=20) were compared with the pro-abortion males (N=50), they reported significantly more obesity and agoraphobia (p.05) and more convictions for a crime (p.1). Comparison of women who had abortion (N=13) with the women who had their baby (N=8) indicated that the latter reported significantly (p.01) more battering by their boyfriend or husband, significantly (p.05) more battering in their family of origin and childhood sexual abuse, and a greater tendency (p.1) to have been raped.

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

  13. Sexy sons: a dead end for cytoplasmic genes.

    2004-08-07

    Critics of sexual conflict theory argue that females may gain a net reproductive benefit from mating with manipulative males because the direct costs that they suffer may be offset by the production of sexy, i.e. manipulative, sons. However, this exclusive focus on nuclear gene effects represents an incomplete view of female fitness. Females differ fundamentally from males in transmitting not only nuclear genes but also a wide range of cytoplasmic genetic elements (CGEs) that can have profound effects, from male killing to influencing development of the nervous system and cognitive ability. Maternal transmission of CGEs has two major implications for sexual selection. First, the evolution of male fitness traits, such as sperm competitive ability, may be constrained because response to selection on mitochondrial genomes can occur only through the female line. Second, CGEs bear the direct costs of male manipulation but gain no indirect benefits when females produce sexy sons. This should result in perpetual antagonistic coevolution between nuclear genes involved in male manipulation and CGEs that promote female resistance to male sexually selected traits. Explicit consideration of the consequences of selection acting on CGEs is therefore necessary for a better understanding of the relationship between sexual selection and sexual conflict.

  14. Evidence mounts for sex-selective abortion in Asia.

    Westley, S B

    1995-01-01

    In Korea, China, and Taiwan--countries where son preference persists--the availability of prenatal screening techniques and induced abortion has produced an imbalance in the naturally occurring sex ratios of 104-107 male births for every 100 female births. Policy responses to sex-selective abortion were the focus of a 1994 International Symposium on Sex Preference for Children in the Rapidly Changing Demographic Dynamics in Asia sponsored by the United Nations Population Fund and the Government of the Republic of Korea. Modern technology (i.e., amniocentesis, ultrasound, and chorionic villi sampling) enables couples to control both family size and sex selection. According to data from the 1990 Korean Census, 80,000 female fetuses were aborted from 1986-90 as a result of son preference. In the late 1980s, the Governments of Korea, China, and India imposed bans on the use of medical technology for prenatal sex determination, but many observers maintain that regulations have served only to make the procedures clandestine and more expensive. To remedy the problems underlying sex-selective abortion, the Symposium recommended the following government actions: 1) implement policies and programs to diminish gender discrimination; 2) establish guidelines for the monitoring and regulation of prenatal testing; 3) utilize mass and folk media, interpersonal channels, and school curricula to promote gender equality; 4) strengthen the ethics curriculum of medical schools to address son preference; and 5) increase the capability of statistical and research organizations to collect gender-disaggregated data.

    1999-09-01

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

    目的:研究无痛人工流产和传统人工流产术式选择对重复流产的影响。方法:选择2011年6-12月在本院妇产科要求行人工流产术妇女共180例(无痛人工流产100例、传统人工流产80例)进行跟踪调查一年。调查内容涉及是否有重复流产,前后两次流产心理状态等。结果:前次行无痛人工流产者重复流产率明显高于传统人工流产组(P<0.05),两组半年内重复流产及前后两次流产的心理状态差异均有统计学意义(P<0.05)。结论:无痛人工流产术虽然解决了术中妇女疼痛问题,但术后存在重复流产率较高的问题,在强调优质流产后计划生育服务时应着重于对无痛人工流产者的术后主动宣教,进行面对面咨询并提供辅助资料、免费药具,以及要求男伴参与,必要时转诊等。%Objective:To study the influence of painless artificial abortion and the traditional artificial abortion on repeat abortion. Method:From June to December 2011,a total of 180 cases of induced abortion women(100 cases of painless artificial abortion and 80 cases of traditional abortion)in the hospital maternity line were selected and followed up one year. The investigation related to whether there was a repeat abortion,both before and after the abortion mental state. Result:Repeat abortion rate of previous painless artificial abortion group was significantly higher than that of the traditional artificial abortion group(P<0.05),significant difference existed before and after six months of repeated abortion and two abortion mental state. Conclusion:Although induced abortion surgery pain problems for women,but duplicate after the higher abortion rate,the emphasis on quality abortion family planning services should focus on postoperative induced abortion initiative education,face-to-face consultation,and provide supporting information,free contraceptives,and the requirements of the male partner to

    Science.gov (United States)

    2014-01-01

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

  19. Reducing abortion-related mortality in South Asia: a review of constraints and a road map for change.

    2002-01-01

    South Asia (Bangladesh, India, Nepal, Pakistan, and Sri Lanka) is home to 28% of the world's people and accounts for about a third (30%) of the world's maternal deaths. Thirteen percent of all maternal deaths in South Asia are attributed to complications of unsafe abortion and are almost entirely preventable. This article reviews the legal, health system, and sociocultural barriers to safe abortion and suggests strategies to reduce abortion-related morbidity and mortality. Restrictive laws hamper safe abortion in most of the region, but even where laws are more liberal, limited awareness of the law has been a barrier to access. Such health system barriers as an insufficient number of trained providers, inequitable distribution of services, and excessive costs have contributed to death from unsafe abortion. Sociocultural attitudes, including the right of male relatives to make reproductive decisions, the emphasis on male heirs, and the strong social stigma against extramarital pregnancy also put women at risk. Government and other institutions must strive to prevent abortion-related death and disability by making safe abortion services accessible to the fullest extent of the law. Health systems need to provide emergency care for complications and postabortion contraceptive counseling, use appropriate technology, and allow nonphysician providers to deliver care. Safe abortion care programs need to address the needs of the local community, particularly the needs of socially and economically vulnerable subgroups, such as the unmarried and adolescents.

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

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

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

    1989-11-01

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

  4. [Legal and illegal abortion in Switzerland].

    1970-01-01

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

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

  6. Induced abortion and contraception in Italy.

    1991-09-01

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

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

    1988-01-01

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

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

  10. Is Induced Abortion Really Declining in Armenia?

    2016-06-01

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

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

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

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

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

    2017-12-01

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

  14. Is "abortion culture" fading in the former Soviet Union? Views about abortion and contraception in Kazakhstan.

    2002-09-01

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

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

    Repeat abortion is a public health concern favored by many obstetric and social factors. The purpose of our study was to identify associated factors to repeated abortion in the region of Monastir (Tunisia). Common mental disorders (CMD) such as anxiety and depression were also evaluated in women seeking voluntary repeated abortion. We carried out a cross sectional study between January and April 2013 in the Reproductive Health Center (RHC) of the region of Monastir in Tunisia (This study is part of a prospective design on mental disorders and intimate partner violence among women seeking abortions in the RHC). Among women referred to the RHC we selected those seeking voluntary abortion (medical or surgical method). Data on women's demographic characters, knowledge and practices about contraceptive methods and abortion were collected the abortion day via a structured questionnaire. Data about anxiety and depression status were evaluated during the post-abortal control visit at 3-4 weeks following pregnancy termination. Of the 500 interviewed women, 211 (42.2 %; CI95% [37.88 - 46.52]) were seeking repeated abortions. Multivariate analysis showed that increased age, lower level of women school education, single status, poor knowledge about birth control methods and history of conflict/abuse by a male partner, were uniquely associated with undergoing repeat compared with initial abortion. CMD were significantly higher in women undergoing second or subsequent abortion (51.1 %) single and lower educated women. Women relating a history of conflicts/abuse report more CMD than others (30.6 % vs 20.8 %). Health facilities providing abortion services need to pay more attention to women seeking repeat abortion. Further studies are needed to well establish the relation between the number of abortion and the occurrence and the severity of CMD.

  18. Rejoinder to Wisniewski on Abortion

    Walter E. Block

    2010-11-01

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

  19. Politics and abortion in Bulgaria.

    Science.gov (United States)

    Sirakova, K

    1992-01-01

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

  1. Cytoplasmic Streaming in the Drosophila Oocyte.

    Quinlan, Margot E

    2016-10-06

    Objects are commonly moved within the cell by either passive diffusion or active directed transport. A third possibility is advection, in which objects within the cytoplasm are moved with the flow of the cytoplasm. Bulk movement of the cytoplasm, or streaming, as required for advection, is more common in large cells than in small cells. For example, streaming is observed in elongated plant cells and the oocytes of several species. In the Drosophila oocyte, two stages of streaming are observed: relatively slow streaming during mid-oogenesis and streaming that is approximately ten times faster during late oogenesis. These flows are implicated in two processes: polarity establishment and mixing. In this review, I discuss the underlying mechanism of streaming, how slow and fast streaming are differentiated, and what we know about the physiological roles of the two types of streaming.

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

    Science.gov (United States)

    1983-01-01

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

    Purpose In addition to genomic signaling, it is accepted that ERα has non-nuclear signaling functions, which correlate with tamoxifen resistance in preclinical models. However, evidence for cytoplasmic ER localization in human breast tumors is less established. We sought to determine the presence and implications of non-nuclear ER in clinical specimens. Experimental Design A panel of ERα-specific antibodies (SP1, MC20, F10, 60c, 1D5) were validated by western blot and quantitative immunofluorescent (QIF) analysis of cell lines and patient controls. Then eight retrospective cohorts collected on tissue microarrays were assessed for cytoplasmic ER. Four cohorts were from Yale (YTMA 49, 107, 130, 128) and four others (NCI YTMA 99, South Swedish Breast Cancer Group SBII, NSABP B14, and a Vietnamese Cohort) from other sites around the world. Results Four of the antibodies specifically recognized ER by western and QIF, showed linear increases in amounts of ER in cell line series with progressively increasing ER, and the antibodies were reproducible on YTMA 49 with pearson’s correlations (r2 values)ranging from 0.87-0.94. One antibody with striking cytoplasmic staining (MC20) failed validation. We found evidence for specific cytoplasmic staining with the other 4 antibodies across eight cohorts. The average incidence was 1.5%, ranging from 0 to 3.2%. Conclusions Our data shows ERα present in the cytoplasm in a number of cases using multiple antibodies, while reinforcing the importance of antibody validation. In nearly 3,200 cases, cytoplasmic ER is present at very low incidence, suggesting its measurement is unlikely to be of routine clinical value. PMID:21980134

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

    The 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. (author)

  9. Prolonged grieving after abortion: a descriptive study.

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

    1993-01-01

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

  10. Abortion checks at German-Dutch border.

    Science.gov (United States)

    Von Baross, J

    1991-05-01

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

    Discursive constructions of abortion are embedded in the social and gendered power relations of a particular socio-historical space. As part of research on public discourses concerning abortion in South Africa where there has been a radical liberalisation of abortion legislation, we collected data from male group discussions about a vignette concerning abortion, and newspaper articles written by men about abortion. Our analysis revealed how discourses of equality, support and rights may be used by men to subtly undermine women's reproductive right to 'choose' an abortion. Within an Equal Partnership discourse, abortion, paired with the assumption of foetal personhood, was equated with violating an equal heterosexual partnership and a man's patriarchal duty to protect a child. A New Man discourse, which positions men as supportive of women, was paired with the assumption of men as rational and women as irrational in decision-making, to allow for the possibility of men dissuading women from terminating a pregnancy. A Rights discourse was invoked to suggest that abortion violates men's paternal rights.

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

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

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

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

    Science.gov (United States)

    Nowicka, W

    1993-06-01

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

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

  17. Attitudes of medical students to induced abortion.

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

    2017-07-01

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

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

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

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

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

  7. Evidence supporting broader access to safe legal abortion.

    2015-10-01

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

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

  12. The Roman Catholic position on abortion.

    Science.gov (United States)

    Barry, R

    1997-01-01

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

  13. Irish women who seek abortions in England.

    1992-01-01

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

  14. Clandestine abortions are not necessarily illegal.

    Science.gov (United States)

    Cook, R J

    1991-01-01

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

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

    Full Text Available A green ciliate Paramecium bursaria, bearing several hundreds of endosymbiotic algae, demonstrates rotational microtubule-based cytoplasmic streaming, in which cytoplasmic granules and endosymbiotic algae flow in a constant direction. However, its physiological significance is still unknown. We investigated physiological roles of cytoplasmic streaming in P. bursaria through host cell cycle using video-microscopy. Here, we found that cytoplasmic streaming was arrested in dividing green paramecia and the endosymbiotic algae proliferated only during the arrest of cytoplasmic streaming. Interestingly, arrest of cytoplasmic streaming with pressure or a microtubule drug also induced proliferation of endosymbiotic algae independently of host cell cycle. Thus, cytoplasmic streaming may control the algal proliferation in P. bursaria. Furthermore, confocal microscopic observation revealed that a division septum was formed in the constricted area of a dividing paramecium, producing arrest of cytoplasmic streaming. This is a first report to suggest that cytoplasmic streaming controls proliferation of eukaryotic cells.

From the omission of the word “abortion”, in the mid-seventies, to the political choice of decriminalization and application of the cases foreseen by law, Brazilian feminism has been marked by the choice of negotiation. The article concludes that these negotiations have succeeded politically but failed to reach society and heighten public awareness at a large scale.

    2018-02-27

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

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

  1. Comment: unethical ethics investment boycotts and abortion.

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

  2. Opposition to legal abortion: challenges and questions.

    1993-01-01

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

    Full Text Available Cloned pigs generated by somatic cell nuclear transfer (SCNT show a greater ratio of early abortion during mid-gestation than normal controls. X-linked genes have been demonstrated to be important for the development of cloned embryos. To determine the relationship between the expression of X-linked genes and abortion of cloned porcine fetuses, the expression of X-linked genes were investigated by quantitative real-time polymerase chain reaction (q-PCR and the methylation status of Xist DMR was performed by bisulfate-specific PCR (BSP. q-PCR analysis indicated that there was aberrant expression of X-linked genes, especially the upregulated expression of Xist in both female and male aborted fetuses compared to control fetuses. Results of BSP suggested that hypomethylation of Xist occurred in aborted fetuses, whether male or female. These results suggest that the abnormal expression of Xist may be associated with the abortion of fetuses derived from somatic cell nuclear transfer embryos.

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

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

  11. Reproductive rights: Current issues of late abortion

    Directory of Open Access Journals (Sweden)

    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. .

  12. The abortion issue in the 1980 elections.

    1983-01-01

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

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

    Kissling, F

    1991-01-01

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

    We report optimized methods for preparing Xenopus egg extracts without cytochalasin D, that we term "actin-intact egg extract." These are undiluted egg cytoplasm that contains abundant organelles, and glycogen which supplies energy, and represents the least perturbed cell-free cytoplasm preparation we know of. We used this system to probe cell cycle regulation of actin and myosin-II dynamics (Field et al., 2011), and to reconstitute the large, interphase asters that organize early Xenopus embryos (Mitchison et al., 2012; Wühr, Tan, Parker, Detrich, & Mitchison, 2010). Actin-intact Xenopus egg extracts are useful for analysis of actin dynamics, and interaction of actin with other cytoplasmic systems, in a cell-free system that closely mimics egg physiology, and more generally for probing the biochemistry and biophysics of the egg, zygote, and early embryo. Detailed protocols are provided along with assays used to check cell cycle state and tips for handling and storing undiluted egg extracts. © 2014 Elsevier Inc. All rights reserved.

    The morphology and function of cytoplasmic lipid bodies in human neutrophils were evaluated. By transmission electron microscopy, neutrophil lipid bodies were cytoplasmic inclusions, usually several microns in diameter, that occasionally coalesced to attain a diameter up to 7 microM. Neutrophil lipid bodies were not enveloped by membrane but were often surrounded by a more electron-dense shell at their periphery. Normal peripheral blood neutrophils contained an average of approximately one lipid body per cell. Lipid bodies appeared in greater numbers in neutrophils from inflammatory lesions. Perturbation of neutrophils during conventional methods of cell isolation and purification modestly increased lipid body numbers in neutrophils, whereas incubation of neutrophils with 1 microM oleic acid rapidly induced lipid body formation over 30 to 60 minutes. After granulocytes were incubated for 2 hours with 3H-fatty acids, including arachidonic, oleic, and palmitic acids, electron microscopic autoradiography demonstrated that lipid bodies represented the predominant intracellular sites of localization of each of the three 3H-fatty acids. There was lesser labeling noted in the perinuclear cisterna, but not in cell membranes. Virtually all of each of the three 3H-fatty acids incorporated by the neutrophils were esterified into chromatographically resolved classes of neutral lipids or phospholipids. These findings indicate that cytoplasmic lipid bodies are more prominent in neutrophils in vivo engaged in inflammatory responses and that these organelles in human neutrophils function as sites of deposition of esterified, incorporated fatty acids

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

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

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

  20. Programmed cell death promotes male sterility in the functional dioecious Opuntia stenopetala (Cactaceae).

    The sexual separation in dioecious species has interested biologists for decades; however, the cellular mechanism leading to unisexuality has been poorly understood. In this study, the cellular changes that lead to male sterility in the functionally dioecious cactus, Opuntia stenopetala, are described. The spatial and temporal patterns of programmed cell death (PCD) were determined in the anthers of male and female flowers using scanning electron microscopy analysis and histological observations, focusing attention on the transition from bisexual to unisexual development. In addition, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling assays were used as an indicator of DNA fragmentation to corroborate PCD. PCD was detected in anthers of both female and male flowers, but their patterns differed in time and space. Functionally male individuals developed viable pollen, and normal development involved PCD on each layer of the anther wall, which occurred progressively from the inner (tapetum) to the outer layer (epidermis). Conversely, functional female individuals aborted anthers by premature and displaced PCD. In anthers of female flowers, the first signs of PCD, such as a nucleus with irregular shape, fragmented and condensed chromatin, high vacuolization and condensed cytoplasm, occurred at the microspore mother cell stage. Later these features were observed simultaneously in all anther wall layers, connective tissue and filament. Neither pollen formation nor anther dehiscence was detected in female flowers of O. stenopetala due to total anther disruption. Temporal and spatial changes in the patterns of PCD are responsible for male sterility of female flowers in O. stenopetala. Male fertility requires the co-ordination of different events, which, when altered, can lead to male sterility and to functionally unisexual individuals. PCD could be a widespread mechanism in the determination of functionally dioecious species.

  1. A measured response: Koop on abortion.

    Koop, C E

    1989-01-01

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

    2009-01-01

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

    Abortion is illegal in most of Mexico, except in the case of rape or physical risk to the mother, but there are several indicators that suggest that at least in Mexico City, society would like to have a more liberal law. The present study was performed to learn what several groups of physicians and medical students residing outside of Mexico City think in this regard. Seven colleagues working in different cities agreed to apply a questionnaire to physicians and or medical students available to them, to learn their opinions regarding the acceptability of induced abortion in several scenarios. Questions one to tree inquires if abortion is acceptable up to week 20 of pregnancy at the simple request of the parents, if the fetus has a severe malformation or anencephaly. Questions four to six personalize the situations by supposing that the physician or spouse have a high risk of having a malformed child. Question seven asks if they would offer prenatal diagnosis to a mother who would abort a malformed fetus. Statistical procedure includes multivariate analysis. The inter-city physicians-students composition was very heterogeneous. The majority of respondents disagreed with abortion on demand of the parents, but clearly agrees to it in the presence of severe malformations. In general males, above 30 years old physicians and less religious individuals, are more in favor to abortion than their respective counterparts. The proportion of acceptance is over 70% in most cases. We believe that this work shows a preliminary indication of a national trend amongst physicians and medical students favoring induced early abortion if the fetus has a severe malformation.

    1994-09-08

    The International Conference on Population and Development, underway in Cairo, has been dominated by acrimonious debate on the issue of abortion. By the third day of the conference, agreement had been reached by 90% of the proposed Program of Action. Delegates appeared to have developed a compromise passage that urged governments to recognize illegal abortion as a major public health problem. However, hours after the compromise, delegations from Argentina, Ecuador, Guatemala, Honduras, Malta, Slovakia, Uruguay, and Guam--all of which have Roman Catholic majorities--withdrew their support, claiming that some phrases were pro-abortion. Many conference participants are concerned that the Vatican and its Muslim allies are forcing the issue of women's lives and health to become subordinated to a male-dominated political struggle.

    In Tyrol a case of fatal air embolism after an abortion attempt with a bicycle pump, performed by a blind man who later committed suicide, is described. The bicycle tube was inserted into the vagina and air and a soapy solution were pumped in. Autopsies revealed internal bleeding, gas embolisms in the veins of the ovaries and heart, a bloody foamy liquid in the lungs, and an intact 14 cm male fetus. 3 similar cases of fatal air embolisms after abortion attempts with bicycle pumps are described. In 1 case a soapy solution had been injected. Abortion attempts with a pipe and a rubber catheter, reported here, also resulted in rapidly fatal air embolisms. In 1 case death occurred a few seconds after a partner blew air with his mouth into his pregnant mistress' vagina. It is concluded that under some conditions filling the vagina with air (tightly) can cause fatal air embolisms.

  12. Evidence Supporting Broader Access To Safe Legal Abortion

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

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

  14. Stigma and abortion complications in the United States.

    Science.gov (United States)

    Harris, Lisa H

    2012-12-01

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

  15. How often and under which circumstances do Mexican pharmacy vendors recommend misoprostol to induce an abortion?

    2011-06-01

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

  16. The power dynamics perpetuating unsafe abortion in Africa: a feminist perspective.

    Science.gov (United States)

    Braam, Tamara; Hessini, Leila

    2004-04-01

    Tens of thousands of African women die every year because societies and governments either ignore the issue of unsafe abortion or actively refuse to address it. This paper explores the issue of abortion from a feminist perspective, centrally arguing that finding appropriate strategies to reclaim women's power at an individual and social level is a central lever for developing effective strategies to increase women's access to safe abortion services. The paper emphasises the central role of patriarchy in shaping the ways power plays itself out in individual relationships, and at social, economic and political levels. The ideology of male superiority denies abortion as an important issue of status and frames the morality, legality and socio-cultural attitudes towards abortion. Patriarchy sculpts unequal gender power relationships and takes power away from women in making decisions about their bodies. Other forms of power such as economic inequality, discourse and power within relationships are also explored. Recommended solutions to shifting the power dynamics around the issue include a combination of public health, rights-based, legal reform and social justice approaches.

  17. Managing Unplanned Pregnancies in Five Countries: Perspectives on Contraception and Abortion Decisions

    Science.gov (United States)

    2014-01-01

    Why is induced abortion common in environments when modern contraception is readily available? This study analyzes qualitative data collected from focus group discussions and in-depth interviews with women and men from low income areas in five countries -- the U.S., Nigeria, Pakistan, Peru and Mexico -- to better understand how couples manage their pregnancy risk. Across all settings, women and men rarely weigh the advantages and disadvantages of contraception and abortion before beginning a sexual relationship or engaging in sexual intercourse. Contraception is viewed independently of abortion, and the two are linked only when the former is invoked as a preferred means to avoiding repeat abortion. Contraceptive methods are viewed as suspect because of perceived side effects, while abortion experience, often at significant personal risk, raised the specter of social stigma and motivation for better contraceptive practice. In all settings, male partners figure importantly in pregnancy decisions and management. Although there are inherent limitations from small sample sizes, the study narratives reveal psychosocial barriers to effective contraceptive use and identify nodal points in pregnancy decision-making that can inform and structure future investigation.

    1997-12-01

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

  2. LHC Abort Gap Filling by Proton Beam

    Fartoukh, Stéphane David; Shaposhnikova, Elena

    2004-01-01

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

  6. The triviality of abortion in Greece.

    Science.gov (United States)

    Naziri, D

    1991-09-01

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

    Full Text Available Objective: The aim of this study was to investigate the opinions of women who presented to the hospital for elective abortion. Materials and Methods: This descriptive study was designed and conducted at our university hospital between March 2013-April 2013 by the method of face-to-face interviews with 500 women who presented to the hospital as patient or relatives of patients. Poll consisted of 6 questions about demographic characteristics and 14 questions evaluating the opinions and attitudes about abortion. Results: The age of the women who participated in the study was ranging between 18 and 75 years with the mean age of 31.5±11.9 years. Twenty-six women (5.2% were illiterate, while 109 (21.8% were university graduates. 70.8% of women stated that they were against elective abortion. Among the reasons against abortion on request were: “forbidden by the religion”-53.1% of women, “against human rights”-35.3%, and “unhealthy for the mother”-7.1% of women. About the prohibition of abortion, 82.4% of women said that “it may be performed under necessary conditions”, 9.6% “it should be completely forbidden”, and 8% stated that “it should never be forbidden”. Conclusion: A large number of respondents reported that they have negative attitude towards elective abortion, however, in case of medical necessity, abortion should be performed. During the legal arrangements done about situations that may affect the public health, such as abortion regulations, we believe it would be useful to assess the perspective of the society on this issue.

  12. Abortion: a technique for working through grief.

    Buckles, N B

    1982-02-01

    Studies have shown that very few women experience significant depression in the weeks following abortion and most have strong feelings of relief and happiness; what mild feelings of guilt, regret, or remorse do exist immediately following abortion tend to diminish quickly. Traditionally attitudes were that abortion could even precipitate psychosis and cause infertility, depression, and sexual dysfunction. The findings of a 1963-65 study of 116 women who underwent abortions indicate that few women had regrets immediately. Studies done after the 1973 Supreme Court decision conclude that even psychiatrically disturbed women who undergo abortion remain stabilized or improved afterwards. Women who do have postabortion problems are usually those who were late aborters, who feel that the decision was not freely made, or that the pregnancy fulfilled certain needs. When working with these women clinicians use a variety of techniques, encouraging the women to express their feelings of loss and anger and supporting the choice that was made, while providing contraceptive and decision making education. The strategy in 3 cases described here involved the woman first saying goodbye to the fetus and her former relationship with it in a gestalt dialogue. The next part of the strategy is establishing positive remembrance of the significant meaning of the fetus to the woman. There are usually 5 sessions at the end of which the woman feels optimistic; the 6th session is a followup 6 months to 1 year later at which most women report no further symptoms.

  14. Abortion for fetal CNS malformations: religious aspects.

    Steinberg, Avraham

    2003-08-01

    Abortion is one of the most widely discussed medical-ethical subjects in medical, legal, philosophical, and religious literature as well as in the lay press. There is hardly a religion or country in the world that is not currently concerned about this issue. The complexity of the topic relates to the fact that it deals with a being that is close to us but not identical to us. On the other hand, the fetus is not like a plant or even like a living being in the animal kingdom. Yet the fetus is not a complete and independent human being either. There are strongly opposing philosophical/religious viewpoints on abortion. On the one hand, pro-life groups and the Roman Catholic Church absolutely oppose abortion. They view the fetus as a full and independent human being, with absolute rights equal to those of the mother. According to this view, the right of the fetus to life can never be disregarded, and abortion is viewed as murder. On the other hand, the permissive, feminist, liberal view, emphasizes the basic right of a woman over her body. This right justifies abortion on demand solely dependent on the woman's wishes at any stage of pregnancy and for any reason whatsoever. This view totally ignores the rights of the fetus and views it as a part of the mother's body. This article deals with some aspects of the approaches of various religions to abortion due to fetal indications, in particular the Jewish viewpoint.

    1991-01-01

    Hoping to provide women other choice besides abortion as a way to regulate fertility, 220 experts from 27 mostly European countries met in Tbilisi, Georgia, USSR to discuss ways of increasing access to modern contraceptives. Held last October, the conference was sponsored by the United Nations Population Fund (UNFPA), the World Health Organization European Regional Office (WHO/EURO), the International Planned Parenthood Federation/Europe, and the Zhordania Institute of Human Reproduction, Tbilisi. The meeting produced the Tbilisi Declaration, which -- among other things -- recognizes that unwanted pregnancies and unsafe abortions pose a serious health and social problem. Criminalization, the experts agreed, does little to reduce the number of abortions, and only increases the number of unsafe operations. The Tbilisi Declaration also affirms women's right to decide freely on the number and spacing of children, their right to reproductive health, their right to self-determination in their sexual and reproductive lives, and the right of every child to be a wanted child. The participants addressed the high incidents of abortion in some European countries -- particularly the Soviet Union. With the highest rate of abortion in Europe, the Soviet Union recorded 6 million legal abortions in 1988, and estimates that another 6 million were performed illegally. Nonetheless, perestroika has begun to facilitate access to contraceptives. Participants also discussed new methods of early pregnancy termination, RU486 and menstrual regulation procedures (MR), neither of which is readily available. Increasing access to these methods would help reduce suffering and unnecessary deaths.

    In Victoria, Australia, abortion was decriminalised in October 2008, bringing the law in line with clinical practice and community attitudes. We describe how experts in abortion service provision perceived the intent and subsequent impact of the 2008 Victorian abortion law reform. Experts in abortion provision in Victoria were recruited for a qualitative semi-structured interview about the 2008 law reform and its perceived impact, until saturation was reached. Nineteen experts from a range of health care settings and geographic locations were interviewed in 2014/2015. Thematic analysis was conducted to summarise participants' views. Abortion law reform, while a positive event, was perceived to have changed little about the provision of abortion. The views of participants can be categorised into: (1) goals that law reform was intended to address and that have been achieved; (2) intent or hopes of law reform that have not been achieved; (3) unintended consequences; (4) coincidences; and (5) unfinished business. All agreed that law reform had repositioned abortion as a health rather than legal issue, had shifted the power in decision making from doctors to women, and had increased clarity and safety for doctors. However, all described outstanding concerns; limited public provision of surgical abortion; reduced access to abortion after 20 weeks; ongoing stigma; lack of a state-wide strategy for equitable abortion provision; and an unsustainable workforce. Law reform, while positive, has failed to address a number of significant issues in abortion service provision, and may have even resulted in a 'lull' in action.

    1972-01-01

    Most of this essay on the abortion problem in French-speaking western Europe concerns the Sermon of Hippocrates forbidding abortion; the discussion ends with an ethical discussion on abortion codes in a pluralist society. 1st, scholars question whether Hippocrates himself actually wrote the text of the Sermon, or whether his Pythagorean followers did. 2nd, probably abortion in Hippocrates' time was relegated to midwives and lithotomists. The meaning of the quotation "I do not give any abortive remedy" is obscure since in other contexts Hippocrates distinguished between abortive and contraceptive drugs and also abortive instruments. Finally, Hipoocrates specifically recommended abortion, e.g., to avoid pregnancy for prostitutes. Persons in authority, then, should not invoke Hippocrates or any other moral code to deprive a woman of medical abortion, especially in cases of rape, age, and failure of contraception. Divorce, for example, has been legalized in most countries, without forcing anyone to take advantage of it.

    In 2007, first trimester abortion was legalized in Mexico City, and the public sector rapidly expanded its abortion services. In 2008, to obtain information on the effect of the law on private sector abortion services, we interviewed 135 physicians working in private clinics, located through an exhaustive search. A large majority of the clinics offered a range of reproductive health services, including abortions. Over 70% still used dilatation and curettage (D&C); less than a third offered vacuum aspiration or medical abortion. The average number of abortions per facility was only three per month; few reported more than 10 abortions monthly. More than 90% said they had been offering abortion services for less than 20 months. Many women are still accessing abortion services privately, despite the availability of free or low-cost services at public facilities. However, the continuing use of D&C, high fees (mean of $157-505), poor pain management practices, unnecessary use of ultrasound, general anaesthesia and overnight stays, indicate that private sector abortion services are expensive and far from optimal. Now that abortions are legal, these results highlight the need for private abortion providers to be trained in recommended abortion methods and quality of private abortion care improved.

    In Scotland, in contrast to the rest of Great Britain, abortion at gestations over 20 weeks is not provided, and provision of procedures above 16 weeks varies considerably between regions. Women at varying gestations above 16 weeks must travel outside Scotland, usually to England, for the procedure. To determine the views of professionals working within Scottish abortion care about a Scottish late abortion service. Delegates at a meeting for abortion providers in Scotland completed a questionnaire about their views on abortion provision over 16 weeks and their perceived barriers to service provision. Of 95 distributed questionnaires, 70 (76%) were analysed. Fifty-six respondents (80%) supported a Scottish late abortion service, ten (14%) would maintain current service arrangements, and five (7%) were undecided. Forty (57%) of the supporters of a Scottish service would prefer a single national service, and 16 (22%) several regional services. Perceived barriers included lack of trained staff (n = 39; 56%), accommodation for the service (n = 34; 48%), and perception of lack of support among senior management (n = 28; 40%). The majority of health professionals surveyed who work in Scottish abortion services support provision of abortion beyond 16 weeks within Scotland, and most favour a single national service. Further work on the feasibility of providing this service is required.

    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.

  5. Medical students' attitudes toward abortion education: Malaysian perspective.

    Nai-peng Tey

    Full Text Available BACKGROUND: Abortion is a serious public health issue, and it poses high risks to the health and life of women. Yet safe abortion services are not readily available because few doctors are trained to provide such services. Many doctors are unaware of laws pertaining to abortion. This article reports survey findings on Malaysian medical students' attitudes toward abortion education and presents a case for including abortion education in medical schools. METHODS AND RESULTS: A survey on knowledge of and attitudes toward abortion among medical students was conducted in two public universities and a private university in Malaysia in 2011. A total of 1,060 students returned the completed questionnaires. The survey covered about 90% of medical students in Years 1, 3, and 5 in the three universities. About 90% of the students wanted more training on the general knowledge and legal aspects of abortion, and pre-and post-abortion counseling. Overall, 75.9% and 81.0% of the students were in favor of including in medical education the training on surgical abortion techniques and medical abortion, respectively. Only 2.4% and 1.7% were opposed to the inclusion of training of these two methods in the curriculum. The remaining respondents were neutral in their stand. Desire for more abortion education was associated with students' pro-choice index, their intention to provide abortion services in future practice, and year of study. However, students' attitudes toward abortion were not significantly associated with gender, type of university, or ethnicity. CONCLUSIONS: Most students wanted more training on abortion. Some students also expressed their intention to provide abortion counseling and services in their future practice. Their desire for more training on abortion should be taken into account in the new curriculum. Abortion education is an important step towards making available safe abortion services to enable women to exercise their reproductive rights.

    To describe obstetrician-gynecologists' (ob-gyns') views and willingness to help women seeking abortion in a variety of clinical scenarios. We conducted a mailed survey of 1,800 U.S. ob-gyns. We presented seven scenarios in which patients sought abortions. For each, respondents indicated if they morally objected to abortion and if they would help patients obtain an abortion. We analyzed predictors of objection and assistance. The response rate was 66%. Objection to abortion ranged from 16% (cardiopulmonary disease) to 82% (sex selection); willingness to assist ranged from 64% (sex selection) to 93% (cardiopulmonary disease). Excluding sex selection, objection was less likely among ob-gyns who were female (odds ratio [OR] 0.5, 95% confidence interval [CI] 0.4-0.8), urban (OR 0.3, 95% CI 0.1-0.7), or Jewish (OR 0.3, 95% CI 0.1-0.7) compared with male, rural, or religiously unaffiliated ob-gyns. Objection was more likely among ob-gyns from the South (OR 1.9, 95% CI 1.2-3.0) or Midwest (OR 1.9, 95% CI 1.2-3.1), and among Catholic, Evangelical Protestant, or Muslim ob-gyns, or those for whom religion was most important, compared with reference. Among ob-gyns who objected to abortion in a given case, approximately two-thirds would help patients obtain an abortion. Excluding sex selection, assistance despite objection was more likely among female (OR 1.8, 95% CI 1.1-2.9) and United States-born ob-gyns (OR 2.2, 95% CI 1.1-4.7) and less likely among southern ob-gyns (OR 0.3, 95% CI 0.2-0.6) or those for whom religion was most important (OR 0.3, 95% CI 0.1-0.7). Most ob-gyns help patients obtain an abortion even when they morally object to abortion in that case. Willingness to assist varies by clinical context and physician characteristics. II.

    2016-12-01

    Ultrasound plays a fundamental role in the management of elective abortions. Although it can improve the quality of post-abortion care, it must not be an obstacle to abortion access. We thus studied the role of ultrasound in pregnancy dating and possible alternatives and analyzed the literature to determine the role of ultrasound in post-abortion follow-up. During an ultrasound scan, the date of conception is estimated by measurement of the crown-rump length (CRL), defined by Robinson, or of the biparietal diameter (BPD), as defined by the French Center for Fetal Ultrasound (CFEF) after 11 weeks of gestation (Robinson and CFEF curves) (grade B). Updated curves have been developed in the INTERGROWTH study. In the context of abortion, the literature recommends the application of a safety margin of 5 days, especially when the CRL and/or BPD measurement indicates a term close to 14 weeks (that is equal or below 80 and 27mm, respectively) (best practice agreement). Accordingly, with the ultrasound measurement reliable to±5 days when its performance meets the relevant criteria, an abortion can take place when the CRL measurement is less than 90mm or the BPD less than 30mm (INTERGROWTH curves) (best practice agreement). While a dating ultrasound should be encouraged, its absence is not an obstacle to scheduling an abortion for women who report that they know the date of their last menstrual period and/or of the at-risk sexual relations and for whom a clinical examination by a healthcare professional is possible (best practice agreement). In cases of intrauterine pregnancy of uncertain viability or of a pregnancy of unknown location, without any particular symptoms, the patient must be able to have a transvaginal ultrasound to increase the precision of the diagnosis (grade B). Various reviews of the literature on post-abortion follow-up indicate that the routine use of ultrasound during instrumental abortions should be avoided (best practice agreement). If it becomes

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

    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.

  13. The molecular mechanism and physiological role of cytoplasmic streaming.

    Cytoplasmic streaming occurs widely in plants ranging from algae to angiosperms. However, the molecular mechanism and physiological role of cytoplasmic streaming have long remained unelucidated. Recent molecular genetic approaches have identified specific myosin members (XI-2 and XI-K as major and XI-1, XI-B, and XI-I as minor motive forces) for the generation of cytoplasmic streaming among 13 myosin XIs in Arabidopsis thaliana. Simultaneous knockout of these myosin XI members led to a reduced velocity of cytoplasmic streaming and marked defects of plant development. Furthermore, the artificial modifications of myosin XI-2 velocity changed plant and cell sizes along with the velocity of cytoplasmic streaming. Therefore, we assume that cytoplasmic streaming is one of the key regulators in determining plant size. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Summary Background Reliable information on the incidence of induced abortion in India is lacking. Official statistics and national surveys provide incomplete coverage. Since the early 2000s, medication abortion has become increasingly available, improving the way women obtain abortions. The aim of this study was to estimate the national incidence of abortion and unintended pregnancy for 2015. Methods National abortion incidence was estimated through three separate components: abortions (medication and surgical) in facilities (including private sector, public sector, and non-governmental organisations [NGOs]); medication abortions outside facilities; and abortions outside of facilities and with methods other than medication abortion. Facility-based abortions were estimated from the 2015 Health Facilities Survey of 4001 public and private health facilities in six Indian states (Assam, Bihar, Gujarat, Madhya Pradesh, Tamil Nadu, and Uttar Pradesh) and from NGO clinic data. National medication abortion drug sales and distribution data were obtained from IMS Health and six principal NGOs (DKT International, Marie Stopes International, Population Services International, World Health Partners, Parivar Seva Santha, and Janani). We estimated the total number of abortions that are not medication abortions and are not obtained in a health facility setting through an indirect technique based on findings from community-based study findings in two states in 2009, with adjustments to account for the rapid increase in use of medication abortion since 2009. The total number of women of reproductive age and livebirth data were obtained from UN population data, and the proportion of births from unplanned pregnancies and data on contraceptive use and need were obtained from the 2015–16 National Family Health Survey-4. Findings We estimate that 15·6 million abortions (14·1 million–17·3 million) occurred in India in 2015. The abortion rate was 47·0 abortions (42·2–52·1) per

  16. Abortion Law and Policy Around the World

    Science.gov (United States)

    2017-01-01

    Abstract The aim of this paper is to provide a panoramic view of laws and policies on abortion around the world, giving a range of country-based examples. It shows that the plethora of convoluted laws and restrictions surrounding abortion do not make any legal or public health sense. What makes abortion safe is simple and irrefutable—when it is available on the woman’s request and is universally affordable and accessible. From this perspective, few existing laws are fit for purpose. However, the road to law reform is long and difficult. In order to achieve the right to safe abortion, advocates will need to study the political, health system, legal, juridical, and socio-cultural realities surrounding existing law and policy in their countries, and decide what kind of law they want (if any). The biggest challenge is to determine what is possible to achieve, build a critical mass of support, and work together with legal experts, parliamentarians, health professionals, and women themselves to change the law—so that everyone with an unwanted pregnancy who seeks an abortion can have it, as early as possible and as late as necessary.

  17. Induced abortion and adolescent mental health.

    Stotland, Nada L

    2011-10-01

    Induced abortion is widely believed - by the public, healthcare professionals, and policy-makers - to lead to adverse mental health sequelae. This belief is false, as it applies both to adult women and adolescents. However, it has been used to rationalize, and been quoted in, restrictive and intrusive legislation in several states and in proposed federal legislation. It is essential for gynecologists to have accurate information, as clinicians, for their patients, and, as key experts, for policy makers. New articles concluding that there are adverse psychological outcomes from induced abortion continue to be published. The methodological flaws in these articles are so serious as to invalidate those conclusions. Several recent scholarly analyses detail these flaws. Methodologically sound studies and reviews continue to demonstrate that psychosocial problems play a role in unwanted conception and the decision to abort unwanted pregnancies but are not the result of abortion. Clinicians may have to reassure patients making decisions about their pregnancies that abortion does not cause psychiatric illness. They can do so on the basis of recent analyses substantiating that finding. (C) 2011 Lippincott Williams & Wilkins, Inc.

    To evaluate the introduction of an early medical abortion program with methotrexate and misoprostol, using a standardized protocol. A total of 1973 women at 34 Planned Parenthood sites participated in a case series of early medical abortion. Ultrasound was used to confirm gestational age of less than 49 days from the first day of the last menstrual period. Women were given intramuscular methotrexate 50 mg/m(2) of body surface area on day 1, and then they inserted misoprostol 800 microg vaginally at home on day 5, 6, or 7. Women were advised to have a suction curettage if the pregnancy appeared viable 2 weeks after methotrexate or if any gestational sac persisted 4 weeks after methotrexate. Outcomes were complete medical abortion and suction curettage. Sixteen hundred fifty-nine women (84.1%) had a complete medical abortion, and 257 (13.0%) had suction curettage. The most common reason for curettage was patient option (8.9%). At 2 weeks after methotrexate use, 1.4% of women had curettage because of a viable pregnancy; at 4 weeks, 1.6% of women had curettage because of a persistent but nonviable pregnancy. One percent of women had curettage because of physician recommendation, most commonly for bleeding. Suction curettage rates decreased with site experience (P <.006) and were lower at early gestational ages (P <.004) and in nulliparous women (P <.004). Medical abortion with methotrexate and misoprostol is safe and effective and can be offered in a community setting.

    In Algeria, the epidemiology of cattle abortions is not well understood. Therefore, the present study aims to estimate the prevalence of abortion in 75 Algerian cattle herds and correlate its possible association with brucellosis positivity and some managerial risk factors. The cattle abortion herd prevalence was 41.33% [95% CI 30.16-52.5%]. As for brucellosis, the serological evidence of brucellosis exposure was observed in 9 out of 75 herds accounting for 12% [95% CI 4.65-19.35] herd seroprevalence. The risk factor analysis using the univariable analysis followed by multivariable logistic regression did confirm that brucellosis positivity (OR = 5.19), mixed herd (OR = 2.5), contact with other herd (OR = 2.91), presence of dog in the herd (OR = 2.89), imported cattle (OR = 1.91), and farmers with less than 2 years' experience (OR = 2.69) as risk factors for abortion in Algerian cattle herds. Targeting these factors using a comprehensive control measure is needed to improve animal welfare and reduce economic losses associated with abortion in dairy cattle.

    Nuclear male sterility is common in flowering plants, but its application in hybrid breeding and seed production is limited because of the inability to propagate a pure male sterile line for commercial hybrid seed production. Here, we characterized a rice nuclear gene essential for sporophytic male fertility and constructed a male sterility system that can propagate the pure male sterile seeds on a large scale. This system is fundamentally advantageous over the current cytoplasmic male steril...

    The object of this study was to describe a group of women applying for legal abortion in relation to their use of contraception and reasons for choosing an abortion. During a period of 13 months (1991-92) a questionnaire was distributed to women applying for legal abortion at Hillerød Hospital in Denmark. Three hundred and thirty-nine women participated. Fifty-nine percent of the women had become pregnant although they had used contraception. As seen in other studies, women still state demographic factors as their most important reasons for choosing an abortion. Women with two or more children do not want to have more children. Single women do not want children without being in a stable relationship. Furthermore occupation and education were frequently stated as important reasons for having an abortion. Economy and housing were not main reasons but contributory factors. Thirty percent of the women expressed ambivalence about the choice of abortion at the time when the abort was due.

    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.

    Abortion was legalized in many states in India in April 1972. This study deals with 2 groups of patients admitted to P.G.I., Chadigarh, with problems of induced septic abortion. Group 1 consisted of 88 patients admitted during the 2 1/2 year period from 1 July 1969 to 31 December 1971, before the legalization of abortion. Group 2 consists of 133 patients admitted during the 2 1/2 year period from 1 July 1973 to 31 December 1975. 1 year after the new abortion law had been in force. Not only has there been an increase in the total number of patients, there has been an increase in the severity of infection. Evidently, the liberalization of the law has encouraged more patients to seek abortions and has encouraged more doctors, lacking proper qualifications, to perform them. The morbidity and mortality with induced septic abortion can only be reduced if enough public propaganda makes the people especially in rural areas conscious of the hazards of induced abortion by "dais" and unqualified personnel, simultaneously making them aware of the provision of law and facilities available at different centers. Meanwhile, the law against unskilled and untrained personnel should be rigorously enforced.

  5. Constructing abortion as a social problem: “Sex selection” and the British abortion debate

    2017-01-01

    Between February 2012 and March 2015, the claim that sex selection abortion was taking place in Britain and that action needed to be taken to stop it dominated debate in Britain about abortion. Situating an analysis in sociological and social psychological approaches to the construction of social problems, particularly those considering “feminised” re-framings of anti-abortion arguments, this paper presents an account of this debate. Based on analysis of media coverage, Parliamentary debate and official documents, we focus on claims about grounds (evidence) made to sustain the case that sex selection abortion is a British social problem and highlight how abortion was problematised in new ways. Perhaps most notable, we argue, was the level of largely unchallenged vilification of abortion doctors and providers, on the grounds that they are both law violators and participants in acts of discrimination and violence against women, especially those of Asian heritage. We draw attention to the role of claims made by feminists in the media and in Parliament about “gendercide” as part of this process and argue that those supportive of access to abortion need to critically assess both this aspect of the events and also consider arguments about the problems of “medical power” in the light of what took place.

  15. Legalization of abortion doubtful in Italy.

    1973-09-03

    A proposal to legalize abortion has been presented to the Italian parliament by Representative Loris Fortuna. Thus far, the bill has the whole-hearted support of only the Radical Party. The Vatican has already voiced its strong opposition to this legislation. "The proposal to legalize abortion, even in certain circumstances, must inevitably be met with resistance and refusal," said Father Concetti, the Vatican representative. Professor Emanuele Lauricella, secretary of the Italian Obstetrics and Gynecology Society, on the other hand, claimed that abortion should be permitted, not only when an immediate danger to the mother's life exists, but also when there are other, simpler health risks. The passage of the bill in the near future, however, is very doubtful.

    1985-01-01

    A prospectively collected group of 93 pregnancies complicated by threatened abortion was carefully monitored throughout pregnancy, during birth and in the perinatal period, and any deviation from a completely uneventful course was registered. Comparison was made with a selected group of 282 non-risk pregnant women. A significant association was found between threatened abortion and the overall number of complications in the second half of pregnancy requiring medical intervention and/or admission to hospital, impending pre-term birth requiring betamimetics, pre-term birth, retention of the placenta, birth weight below 2000 g, light-for-dates infants in case of pre-term birth or birth weight below 2000 g, and hyperbilirubinemia in infants with birth weight below 2000 g. The incidences of perinatal mortality and congenital malformations did not differ significantly from those of the control group. Pregnancies complicated by threatened abortion constitute a risk group requiring careful obstetric and perinatal supervision and follow-up.

    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.

    Over the past several years, Fermilab has been operating with a single turn proton abort system in both the superconducting Tevatron and the conventional Main Ring. The abort kicker power supply for this system discharges a lumped capacitance into the inductive magnet load, causing the beam to enter the abort channel. A unique feature of this design is the high voltage, high current diode assembly used to clip the recharge of the capacitor bank. This allows the current to decay slowly with the L/R time constant of the magnet and diode series combination. Special attention will be given to the diode characteristics needed for this passive switching element. Operational experience and proposed upgrades will be given for the two operational systems

  19. Portugal takes step back on abortion legalization.

    1998-07-01

    According to international press reports, a law that would have allowed Portuguese women abortions through the 10th week of pregnancy and into the 16th week if their physical or mental health was at risk has been rescinded after a referendum to determine the statute's future was voided because of low voter turnout. Passed in February, the law was a liberalization of Portugal's strict anti-abortion laws, which ban all abortions except for narrowly defined medical reasons or in the case of rape (and those are permitted only until the 12th week of pregnancy). Because the issue is such a controversial one, politicians had turned to a national referendum asking Portuguese voters to overturn or ratify the new law. The referendum was the first in the country since the end of its right-wing dictatorship in 1974, and 50% participation was required. Only 31.5% of the country's 8.5 million eligible voters went to the polls on June 28. Of those voting, 50.9% voted against the liberalized new legislation. Sunny weather and World Cup soccer matches were both pointed to as reasons for the low turnout. Officials estimate there are some 20,000 illegal abortions annually in Portugal. Abortion-rights activists in the mostly Roman-Catholic country say hospitals see roughly 10,000 women a year suffering from complications from illegal abortions, and that at least 800 women die each year from the procedure. In the next day's Diario de Noticias, a daily paper in Portugal, the entire front page was filled with a giant question mark. "What now, lawmakers?" the headline read. full text

    Over the past several years, Fermilab has been operating with a single turn proton abort system in both the superconducting Tevatron and the conventional Main Ring. The abort kicker power supply for this system discharges a lumped capacitance into the inductive magnet load, causing the beam to enter the abort channel. The characteristics of this current waveform are defined by the requirements of the machine operation. The standard fixed target running mode calls for 12 booster batches of beam which leaves a rotating gap in the beams of approx.1.8 μs. The current waveform is required to rise to 90% of I/sub max/ in this time to avoid beam loss from partially deflected beam. Aperture limitations in both the accelerator and the abort channel demand that the current in the magnets stays above this 90% I/sub max/ for the 21 μs needed to ensure all the beam has left the machine. The 25 mm displacement needed to cleanly enter the abort channel at 1 TeV corresponds to a maximum current in each of the 4 modules of approx.20 kA. Similar constraints are needed for the Main Ring and Tevatron antiproton abort systems. A unique feature of this design is the high voltage, high current diode assembly used to clip the recharge of the capacitor bank.

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

    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

The theoretical framework I use is the pragma-dialectical theory of argumentation (van Eemeren and Grootendorst 1992, 2004 which conceives of fallacies as violations of the rules for critical discussion. I will focus on the fallacies resulting from the violation of the relevance rule in two fragments of argumentative texts illustrating opposing positions on abortion. I claim that these fallacies function as winning strategies in the ethical dispute in case.

    Kicker magnets typically represent the most important contributors to the transverse impedance budget of accelerators and storage rings. Methods of reducing the impedance value of the SNS extraction kicker presently under construction and, in view of a future performance upgrade, that of the RHIC abort kicker have been thoroughly studied at this laboratory. In this paper, the investigation of a potential improvement from using ferrite different from the BNL standard CMD5005 is reported. Permeability measurements of several ferrite types have been performed. Measurements on two kicker magnets using CMD5005 and C2050 suggest that the impedance of a magnet without external resistive damping, such as the RHIC abort kicker, would benefit

    Multiple cellular stressors, including activation of the tumour suppressor p53, can stimulate autophagy. Here we show that deletion, depletion or inhibition of p53 can induce autophagy in human, mouse and nematode cells subjected to knockout, knockdown or pharmacological inhibition of p53. Enhanced autophagy improved the survival of p53-deficient cancer cells under conditions of hypoxia and nutrient depletion, allowing them to maintain high ATP levels. Inhibition of p53 led to autophagy in enucleated cells, and cytoplasmic, not nuclear, p53 was able to repress the enhanced autophagy of p53(-/-) cells. Many different inducers of autophagy (for example, starvation, rapamycin and toxins affecting the endoplasmic reticulum) stimulated proteasome-mediated degradation of p53 through a pathway relying on the E3 ubiquitin ligase HDM2. Inhibition of p53 degradation prevented the activation of autophagy in several cell lines, in response to several distinct stimuli. These results provide evidence of a key signalling pathway that links autophagy to the cancer-associated dysregulation of p53.

  12. Cytoplasmic Dynein Promotes HIV-1 Uncoating

    Directory of Open Access Journals (Sweden)

    Paulina Pawlica

    2014-11-01

    Full Text Available 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.

    2015-08-06

    Organisms show a remarkable range of sizes, yet the dimensions of a single cell rarely exceed 100 µm. 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 spiralling bands of molecular motors at the cell periphery drive the cellular fluid up and down at speeds up to 100 µm s(-1), 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-organization phenomena in establishing the observed patterns of streaming.

    To determine positivity and clinical correlation of anti-neutrophil cytoplasmic antibodies (ANCA), taking into account the interference of antinuclear antibodies (ANA). A prospective study was conducted in the Laboratory of Immunology of the National Cuban Center of Medical Genetic during one year. Two hounded sixty-seven patients with indication for ANCA determination were included. ANCA and ANA determinations with different cut off points and assays were determined by indirect immunofluorescense. Anti proteinase 3 and antimyeloperoxidase antibodies were determined by ELISA. Most positivity for ANCA was seen in patients with ANCA associated, primary small-vessel vasculitides, rheumatoid arthritis and systemic lupus erythematosus. Presence of ANCA without positivity for proteinase 3 and myeloperoxidase was higher in patients with ANA and little relation was observed between the perinuclear pattern confirmed in formalin and specificity by myeloperoxidase. Highest sensibility and specificity values for vasculitides diagnostic were achieved by ANCA determination using indirect immunofluorescense with a cut off 1/80 and confirming antigenic specificities with ELISA. ANCA can be present in a great number of chronic inflammatory or autoimmune disorders in the population studied. This determination using indirect immunofluorescence and following by ELISA had a great value for vasculitis diagnosis. Anti mieloperoxidasa assay has a higher utility than the formalin assay when ANA is present. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    Subsequent to the legalization of abortion in Italy in 1978, abortion; rates among Italian women first rose and then declined steadily, from a peak of 16.9 abortions per 1,000 women of reproductive age in 1983 to 9.8 per 1,000 in 1993. Abortion rates vary considerably by geographic region, with rates typically highest in the more secular and modernized regions and lowest in regions where traditional values predominate. Data from 1981 and 1991 indicate that age-specific abortion rates decreased during the 1980s for all age-groups, with the largest declines occurring in regions with the highest levels of abortion. Moreover, a shift in the age distribution of abortion rates occurred during the 1980s, with women aged 30-34 registering the highest abortion rate in 1991, whereas in 1981 the highest level of abortion occurred among those aged 25-29. The abortion rate among adolescent women was low at both times (7.6 per 1,000 in 1981 and 4.6 per 1,000 in 1991). These data are based only on reported legal abortions; the number of clandestine abortions remains unknown.

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

    Directory of Open Access Journals (Sweden)

    Pablo Tortosa

    2010-03-01

    Full Text Available 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.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.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.

    Background Rural induced abortion service has declined in Canada. Factors influencing abortion provision by rural physicians are unknown. This study assessed distribution, practice, and experiences among rural compared to urban abortion providers in the Canadian province of British Columbia (BC). Methods We used mixed methods to assess physicians on the BC registry of abortion providers. In 2011 we distributed a previously-published questionnaire and conducted semi-structured interviews. Results Surveys were returned by 39/46 (85%) of BC abortion providers. Half were family physicians, within both rural and urban cohorts. One-quarter (17/67) of rural hospitals offer abortion service. Medical abortions comprised 14.7% of total reported abortions. The three largest urban areas reported 90% of all abortions, although only 57% of reproductive age women reside in the associated health authority regions. Each rural physician provided on average 76 (SD 52) abortions annually, including 35 (SD 30) medical abortions. Rural physicians provided surgical abortions in operating rooms, often using general anaesthesia, while urban physicians provided the same services primarily in ambulatory settings using local anaesthesia. Rural providers reported health system barriers, particularly relating to operating room logistics. Urban providers reported occasional anonymous harassment and violence. Conclusions Medical abortions represented 15% of all BC abortions, a larger proportion than previously reported (under 4%) for Canada. Rural physicians describe addressable barriers to service provision that may explain the declining accessibility of rural abortion services. Moving rural surgical abortions out of operating rooms and into local ambulatory care settings has the potential to improve care and costs, while reducing logistical challenges facing rural physicians.

    Induced abortion accounts for 1 in 8 of approximately 600000 maternal deaths that occur annually worldwide. Induced abortion rate can be considered as one of the indicators for assessing availability of the appropriate reproductive health plans for women and identifying needs for appropriate related health policies and programs. Researchers searched Pubmed, Google Scholar, CINAHL, Embase, PsycINFO, Cochrane, Iranian Scientific Information Database (SID), Iranian biomedical journals (Iranmedex), and Iranian Research Institute of Information and Documentation (Irandoc) between January 2000 and June 2013, which reported induced abortion. Search terms from two categories including abortion and termination of pregnancy were compiled. The search terms were "induced abortion", "illegal abortion", "illegal abortion", "unsafe abortion", and "criminal abortion". The search was also conducted with "induced termination of pregnancy", "illegal termination of pregnancy", "illegal termination of pregnancy", "unsafe termination of pregnancy" and "criminal termination of pregnancy". Meta-analysis was carried out by using OpenMeta software. Induced abortion rates were calculated based on the random effect model. Overall induced abortion rate was obtained 58.1 per 1000 women (95%CI: 55.16-61.04). In continental level, rate of induced abortion was 14 per 1000 women (95%CI: 11-16). Nation-wide and local rates were obtained 67.27 per 1000 women (95% CI: 60.02-74.23) and 148.92 (95% CI: 140.06-157.79) respectively. Induced abortion is a major public health problem that occurs worldwide whether under the legal restriction or freedom, and it remains as reproductive health concern globally. To eliminate the need for induced abortion is at the core of any effort for preventing this issue. Option with the highest priority is to prevent unwanted pregnancies through promoting reproductive health plans for women of reproductive age. In case the prevention strategies fail, universal provision of

  12. Antineutrophil Cytoplasmic Antibodies, Autoimmune Neutropenia, and Vasculitis

    2011-01-01

    Objectives Reports of an association between antineutrophil cytoplasmic antibodies (ANCA) and autoimmune neutropenia have rarely included cases of proven vasculitis. A case of ANCA-associated vasculitis (AAV) with recurrent neutropenia is described and relevant literature on the association between ANCA, neutropenia, and vasculitis is reviewed. Methods Longitudinal clinical assessments and laboratory findings are described in a patient with AAV and recurrent episodes of profound neutropenia from December 2008 – October 2010. A PubMed database search of the medical literature was performed for papers published from 1960 through October 2010 to identify all reported cases of ANCA and neutropenia. Results A 49 year-old man developed recurrent neutropenia, periodic fevers, arthritis, biopsy-proven cutaneous vasculitis, sensorineural hearing loss, epididymitis, and positive tests for ANCA with specificity for antibodies to both proteinase 3 and myeloperoxidase. Antineutrophil membrane antibodies were detected during an acute neutropenic phase and were not detectable in a post-recovery sample, whereas ANCA titers did not seem to correlate with neutropenia. An association between ANCA and neutropenia has been reported in 74 cases from 24 studies in the context of drug/toxin exposure, underlying autoimmune disease, or chronic neutropenia without underlying autoimmune disease. In these cases, the presence of atypical ANCA patterns and other antibodies were common; however, vasculitis was uncommon and when it occurred was usually limited to the skin and in cases of underlying toxin exposure. Conclusions ANCA is associated with autoimmune neutropenia, but systemic vasculitis rarely occurs in association with ANCA and neutropenia. The interaction between neutrophils and ANCA may provide insight into understanding both autoimmune neutropenia and AAV. PMID:21507463

    Abstract To determine the prevalence of antineutrophil cytoplasmic antibodies (ANCA) in patients with infective endocarditis (IE) in internal medicine; and to compare clinical and biochemical features and outcome between patients exhibiting IE with and without ANCA. Fifty consecutive patients with IE underwent ANCA testing. The medical records of these patients were reviewed. Of the 50 patients with IE, 12 exhibited ANCA (24%). ANCA-positive patients with IE exhibited: longer duration between the onset of first symptoms and IE diagnosis (P = 0.02); and more frequently: weight loss (P = 0.017) and renal impairment (P = 0.08), lower levels of C-reactive protein (P = 0.0009) and serum albumin (P = 0.0032), involvement of both aortic and mitral valves (P = 0.009), and longer hospital stay (P = 0.016). Under multivariate analysis, significant factors for ANCA-associated IE were: longer hospital stay (P = 0.004), lower level of serum albumin (P = 0.02), and multiple valve involvement (P = 0.04). Mortality rate was 25% in ANCA patients; death was because of IE complications in all these patients. Our study identifies a high prevalence of ANCA in unselected patients with IE in internal medicine (24%). Our findings further underscore that ANCA may be associated with a subacute form of IE leading to multiple valve involvement and more frequent renal impairment. Because death was due to IE complications in all patients, our data suggest that aggressive therapy may be required to improve such patients’ outcome. PMID:26817911

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

    Science.gov (United States)

    Coleman, Mary Clayton

    2013-02-01

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

  16. Abortion legalization and childbearing in Mexico1

    2016-01-01

    In 2007 abortion was legalized in the Federal District of Mexico, making the largest jurisdiction in Latin America, outside of Cuba, to allow women to have abortions on request during the first trimester of pregnancy. While the implications of the law for women's health and maternal mortality have been investigated, its potential association with fertility behavior has yet to be assessed. In this paper, we examine metropolitan area differences in overall and parity-specific, as well as the age pattern of childbearing between 2000 and 2010 to more precisely isolate the contribution of abortion legalization to fertility in Mexico. Our statistical specification applies difference-in-difference regression methods that control for concomitant changes in other socioeconomic predictors of fertility to assess the differential influence of the law across age groups. In addition, we account for prior fertility levels and change to better separate the effect of the law from preceding trends. Overall, the evidence suggests a systematic association between abortion legalization and fertility. The law appears to have contributed to lower fertility in Mexico City compared to other metropolitan areas and prior trends, though the influence is mostly visible among women aged 20-34 in connection with the transition to first and second child with limited impact on teenage fertility. There is some evidence that its effect might be diffusing to the greater Mexico City metropolitan area. PMID:27285423

  20. Is there a 'new ethics of abortion'?

    Science.gov (United States)

    Gillon, R

    2001-10-01

    This paper argues that the central issue in the abortion debate has not changed since 1967 when the English parliament enacted the Abortion Act. That central issue concerns the moral status of the human fetus. The debate here is not, it is argued, primarily a moral debate, but rather a metaphysical debate and/or a theological debate--though one with massive moral implications. It concerns the nature and attributes that an entity requires to have "full moral standing" or "moral inviolability" including a "right to life". It concerns the question when, in its development from newly fertilised ovum to unequivocally mature, autonomous morally inviolable person does a human being acquire that nature and those attributes, and thus a "right to life". The paper briefly reviews standard answers to these questions, outlining some problems associated with each. Finally there is a brief discussion of one way in which the abortion debate has changed since 1967--notably in the increasingly vociferous claim, especially from disability rights sectors, that abortion on grounds of fetal abnormality implies contempt for and rejection of disabled people--a claim that is rebutted.

  1. Constitutional developments in Latin American abortion law.

    Science.gov (United States)

    Bergallo, Paola; Ramón Michel, Agustina

    2016-11-01

    For most of the 20th Century, restrictive abortion laws were in place in continental Latin America. In recent years, reforms have caused a liberalizing shift, supported by constitutional decisions of the countries' high courts. The present article offers an overview of the turn toward more liberal rules and the resolution of abortion disputes by reference to national constitutions. For such purpose, the main legal changes of abortion laws in the last decade are first surveyed. Landmark decisions of the high courts of Argentina, Bolivia, Colombia, and Mexico are then analyzed. It is shown that courts have accepted the need to balance interests and competing rights to ground less restrictive laws. In doing so, they have articulated limits to protection of fetal interests, and basic ideas of women's dignity, autonomy, and equality. The process of constitutionalization has only just begun. Constitutional judgments are not the last word, but they are important contributions in reinforcing the legality of abortion. Copyright © 2016 International Federation of Gynecology and Obstetrics.

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

    The purpose of this study was to conduct a comparison, using qualitative analytic methodology, of perceptions concerning abortion among health care providers and administrators, along with politicians and anti-abortion activists (total n = 75) in Great Britain, Sweden, The Netherlands, and the United States. In none of these countries was there consensus about abortion prior to legalization, and, in all countries, public discussion continues to be present. In general, after legalization of abortion has no longer made it a volatile issue European countries have refocused their energy into providing family planning services, education, and more straightforward access to abortion compared with similar activities in the United States.

    Tedesco, Mark B.; Evans, Bryan M.; Merritt, Deborah S.; Falck, Robert D.

    2007-01-01

    The Crew Exploration Vehicle (CEV) is required to maintain continuous abort capability from lift off through destination arrival. This requirement is driven by the desire to provide the capability to safely return the crew to Earth after failure scenarios during the various phases of the mission. This paper addresses abort trajectory design considerations, concept of operations and guidance algorithm prototypes for the portion of the ascent trajectory following nominal jettison of the Launch Abort System (LAS) until safe orbit insertion. Factors such as abort system performance, crew load limits, natural environments, crew recovery, and vehicle element disposal were investigated to determine how to achieve continuous vehicle abort capability.

    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.

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.

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

    Science.gov (United States)

    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.

  13. Later abortions and mental health: psychological experiences of women having later abortions--a critical review of research.

    2011-01-01

    Some abortion policies in the U.S. are based on the notion that abortion harms women's mental health. The American Psychological Association (APA) Task Force on Abortion and Mental Health concluded that first-trimester abortions do not harm women's mental health. However, the APA task force does not make conclusions regarding later abortions (second trimester or beyond) and mental health. This paper critically evaluates studies on later abortion and mental health in order to inform both policy and practice. Using guidelines outlined by Steinberg and Russo (2009), post 1989 quantitative studies on later abortion and mental health were evaluated on the following qualities: 1) composition of comparison groups, 2) how prior mental health was assessed, and 3) whether common risk factors were controlled for in analyses if a significant relationship between abortion and mental health was found. Studies were evaluated with respect to the claim that later abortions harm women's mental health. Eleven quantitative studies that compared the mental health of women having later abortions (for reasons of fetal anomaly) with other groups were evaluated. Findings differed depending on the comparison group. No studies considered the role of prepregnancy mental health, and one study considered whether factors common among women having later abortions and mental health problems drove the association between later abortion and mental health. Policies based on the notion that later abortions (because of fetal anomaly) harm women's mental health are unwarranted. Because research suggests that most women who have later abortions do so for reasons other than fetal anomaly, future investigations should examine women's psychological experiences around later abortions.

    A proposed California law will require student health centers at public universities to provide medication abortion. To understand its potential impact, we sought to describe current travel time, costs, and wait times to access care at the nearest abortion facilities. We projected total medication abortion use based on campus enrollment figures and age- and state-adjusted abortion rates. We calculated distance and public transit time from campuses to the nearest abortion facility. We contacted existing abortion-providing facilities to determine costs, insurance acceptance, and wait times. We estimate 322 to 519 California public university students seek medication abortions each month. As many as 62% of students at these universities were more than 30 minutes from the closest abortion facility via public transportation. Average cost of medication abortion was $604, and average wait time to the first available appointment was one week. College students face cost, scheduling, and travel barriers to abortion care. Offering medication abortion on campus could reduce these barriers. Copyright © 2018 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

  15. Theorizing Time in Abortion Law and Human Rights.

    The legal regulation of abortion by gestational age, or length of pregnancy, is a relatively undertheorized dimension of abortion and human rights. Yet struggles over time in abortion law, and its competing representations and meanings, are ultimately struggles over ethical and political values, authority and power, the very stakes that human rights on abortion engage. This article focuses on three struggles over time in abortion and human rights law: those related to morality, health, and justice. With respect to morality, the article concludes that collective faith and trust should be placed in the moral judgment of those most affected by the passage of time in pregnancy and by later abortion-pregnant women. With respect to health, abortion law as health regulation should be evidence-based to counter the stigma of later abortion, which leads to overregulation and access barriers. With respect to justice, in recognizing that there will always be a need for abortion services later in pregnancy, such services should be safe, legal, and accessible without hardship or risk. At the same time, justice must address the structural conditions of women's capacity to make timely decisions about abortion, and to access abortion services early in pregnancy.

    2010-10-01

    Abortion remains a highly contentious moral issue, with the debate usually framed as a battle between the fetus's right to life and the woman's right to choose. Often overlooked in this debate is the impact of the concurrent legalization of abortion and the development of new prenatal screening tests on the birth prevalence of many inherited diseases. Most proponents of abortion support abortion for fetuses with severe congenital diseases, but there has unfortunately been, in our opinion, too little debate over the moral appropriateness of abortion for much less severe congenital conditions such as Down's syndrome, deafness, and dwarfism. Due to scientific advances, we are looking at a future in which prenatal diagnosis will be safer and more accurate, raising the specter, and the concomitant ethical concerns, of wholesale abortions. Herein, we present a reframing of the abortion debate that better encompasses these conditions and offers a more nuanced position. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    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......-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....... Results The incidence rates of first psychiatric contact per 1000 person-years among girls and women who had a first abortion were 14.6 (95% confidence interval [CI], 13.7 to 15.6) before abortion and 15.2 (95% CI, 14.4 to 16.1) after abortion. The corresponding rates among girls and women who had a first...

    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

    Eukaryotes carry numerous asexual cytoplasmic genomes (mitochondria and plastids). Lacking recombination, asexual genomes should theoretically suffer from impaired adaptive evolution. Yet, empirical evidence indicates that cytoplasmic genomes experience higher levels of adaptive evolution than predicted by theory. In this study, we use a computational model to show that the unique biology of cytoplasmic genomes-specifically their organization into host cells and their uniparental (maternal) inheritance-enable them to undergo effective adaptive evolution. Uniparental inheritance of cytoplasmic genomes decreases competition between different beneficial substitutions (clonal interference), promoting the accumulation of beneficial substitutions. Uniparental inheritance also facilitates selection against deleterious cytoplasmic substitutions, slowing Muller's ratchet. In addition, uniparental inheritance generally reduces genetic hitchhiking of deleterious substitutions during selective sweeps. Overall, uniparental inheritance promotes adaptive evolution by increasing the level of beneficial substitutions relative to deleterious substitutions. When we assume that cytoplasmic genome inheritance is biparental, decreasing the number of genomes transmitted during gametogenesis (bottleneck) aids adaptive evolution. Nevertheless, adaptive evolution is always more efficient when inheritance is uniparental. Our findings explain empirical observations that cytoplasmic genomes-despite their asexual mode of reproduction-can readily undergo adaptive evolution. © The Author 2016.

    Induced abortion is the termination of pregnancy through a deliberate intervention intended to end the pregnancy. This practice is widespread in Nigeria despite the restrictive abortion laws in Nigeria. Many women still undergo induced abortion every year and endanger their health and lives as induced abortion can only be procured illegally in Nigeria. We hope to determine the proportion of undergraduate students who had induced abortion in the past and the contributing factors. To determine the proportion of the undergraduate students who support the restrictive abortion laws in Nigeria. A cross sectional questionnaire survey of undergraduate students of the University of Port Harcourt was done through a cluster sampling method along with focus group discussion with some of the respondents. 451 out of 500 administered questionnaires were retrieved and analyzed. The incidence of induced abortion amongst the respondents was 47.2%. About 40% had never used an effective form of contraception in the past and 13% were unaware of contraception. 77.9% of the induced abortion was by dilation and curettage and 1% by manual vacuum aspiration. Up to two third of the respondents were against legalization of abortion. Up to 47% of these undergraduates had performed abortion in the past. Protecting educational career was the single most important reason for this. Although most of these undergraduates are against legalizing abortion, they highly patronize unsafe abortion. Improving contraceptive awareness and usage will reduce unwanted pregnancy and induced abortion. This option appears next to total abstinence in reducing the morbidity and mortality from induced abortion in this country.

    History of induced abortion in Denmark from 1200 to 1979 is reviewed. The 1st Danish law of 1200 did not touch upon the question of induced abortion. From the beginning of the 13th century to Religious Reformation in 1536, Roman Catholic law influenced every aspect of Danish life including induced abortion. In 1683 in King Christian V's constitution called Dansk Lov induced abortion was discussed. Immoral women who aborted fetuses or killed newborn babies were decapitated. In Copenhagen in the years 1624-1632 and 1638-1663 17 women were executed because of induced abortion or murder of newborn babies. Although Dansk Lov was effective till 1866, Danish kings came to treat female criminals less severely since about 1780-1800. For example, between 1855 and 1866 42 women convicted of murder of newborn babies or abortion were given pardon (12 years of imprisonment instead of life sentence). In 1866, abortion and murder of babies were treated separately in the Danish criminal law. Induced abortion meant up to 8 years of imprisonment and labor. In 1930 life sentence was abolished; induced abortion called for only up to 2 years of imprisonment, while those who assisted for money were punished more severely (up to 8 years in prison). In 1937 the Danes legalized induced abortion for medical, ethical, (e.g. rape case) and eugenic reasons. By 1973 legalized abortion was available, free of charge, to every Danish female resident within 12 weeks of pregnancy. In 1980 abortion rate was about 41% of total births. It is estimated 2/3 of Danish women experience abortion. Lastly, illegitimate births and miscarriages are on the rise due to changes in women's social status and role.

  5. D & E midtrimester abortion: a medical innovation.

    With the advent of legalized abortion in the US in 1973, the innovation, adoption and dissemination of new and improved medical procedures for the voluntary termination of pregnancy became an important objective. 3 principal techniques were introduced: suction curettage, instillation procedures using saline solution or prostaglandin, and dilatation and evacuation (D and E). Suction curettage in the 1st trimester was readily adopted because the procedure was less traumatic than the traditional dilatation and curettage. Instillation procedures for abortions in the 2nd trimester were also readily adopted. Physicians preferred them to surgical procedures, were familiar with the delivery simulation, and were comfortable with the hospital setting in which the procedure was performed. D and E, an extension of the suction procedure to abortions in the 2nd trimester has lower complication rates than instillation procedures and can be performed early in the midtrimester. A 1981 membership survey conducted by the National Abortion Federation found that about 1/3 of the members performed D and E midtrimester abortions, a wider acceptance than was expected. In 1978, of the 2nd trimester abortions, 85% of the early midtrimester and 25% of the 16 weeks gestation or later abortions were done by D and E. Acceptance in some other countries is also increasing. A study of the relationship of a history of 2nd trimester abortions and subsequent adverse pregnancy outcomes was unable to identify any statistically significant relationship with the possible exception of low birth weight infants. According to a 1976 survey of teaching hospitals, less than 1/4 require their residents to perform midtrimester abortions. Very few medical schools include D and E procedures in their residency training programs. Residents should use the D and E technique only under supervision and after becoming experienced in 1st trimester suction curettage. A survey reported that D and E techniques can be learned

    Under the need to rescue hybrid pearl millet cultivation in India from devastating damage by downy mildew, a mutation induction project was started in 1971 to make the commonly used male sterile parent Tift 23A resistant to the disease. Simultaneously sources of resistance from West Africa were used in crossbreeding by which climatic adaptation and male sterility had to be transferred. A number of mildew-resistant hybrids were developed, both from induced mutation and introduction. The resistant male sterile lines were further examined as to their common features and differences from susceptible lines. A strong evidence for nuclear-cytoplasmic interaction was obtained by biochemical and ultrastructural investigations. (author)

    Unsafe abortion is a leading cause of death among young women aged 10-24 years in sub-Saharan Africa. Although having multiple induced abortions may exacerbate the risk for poor health outcomes, there has been minimal research on young women in this region who have multiple induced abortions. The objective of this study was therefore to assess the prevalence and correlates of reporting a previous induced abortion among young females aged 12-24 years seeking abortion-related care in Kenya. We used data on 1,378 young women aged 12-24 years who presented for abortion-related care in 246 health facilities in a nationwide survey conducted in 2012. Socio-demographic characteristics, reproductive and clinical histories, and physical examination assessment data were collected from women during a one-month data collection period using an abortion case capture form. Nine percent (n = 98) of young women reported a previous induced abortion prior to the index pregnancy for which they were receiving care. Statistically significant differences by previous history of induced abortion were observed for area of residence, religion and occupation at bivariate level. Urban dwellers and unemployed/other young women were more likely to report a previous induced abortion. A greater proportion of young women reporting a previous induced abortion stated that they were using a contraceptive method at the time of the index pregnancy (47 %) compared with those reporting no previous induced abortion (23 %). Not surprisingly, a greater proportion of young women reporting a previous induced abortion (82 %) reported their index pregnancy as unintended (not wanted at all or mistimed) compared with women reporting no previous induced abortion (64 %). Our study results show that about one in every ten young women seeking abortion-related care in Kenya reports a previous induced abortion. Comprehensive post-abortion care services targeting young women are needed. In particular, post-abortion

    Full Text Available Traditional inefficient contraception, incorporated to a large extent in the system of values, has become a natural part of sexual relations in Serbia and represents a rational preventive choice from the individual standpoint. However, when pregnancy is unwanted or cannot be accepted out of any reasons abortion is used as a resort. For this reason there is a long history of a large number of abortions in Serbia. Research findings in our country identify the following, as the most important factors for not accepting modern values in this sphere: traditional contraception and abortion have a firm social confirmation; there is a trans-generational transfer of psychological resistance towards the use of combined oral contraception pills and intrauterine devices; sexual education has never become a natural way of growing up in the family, nor is a constituent part of school programs and that distinct obstacles of various nature exist regarding contraception availability. A developed network of various types of family planning counseling is an important determinant of the accessibility of contraceptive means and methods. There are, however, numerous conditions which have to be fulfilled in order for the contraception counseling services to function properly. Among them, motivated personnel who acquired general and specific knowledge for work in this field are an especially important prerequisite. This theoretical assumption opens the question -whether gynecologists represent an important factor of slow transition of birth control in Serbia? We searched for the answer in the research analyses obtained through two in-depth surveys which either had to do with this theme or tried to determine the knowledge, attitude and practice of gynecologists. The first research regarding the determination of the causes for a large number of abortions in our country, was directed towards women who decided on abortion. Gynecologists were the target group in the second

  10. No influence of Indy on lifespan in Drosophila after correction for genetic and cytoplasmic background effects.

    Janne M Toivonen

    2007-06-01

    Full Text Available To investigate whether alterations in mitochondrial metabolism affect longevity in Drosophila melanogaster, we studied lifespan in various single gene mutants, using inbred and outbred genetic backgrounds. As positive controls we included the two most intensively studied mutants of Indy, which encodes a Drosophila Krebs cycle intermediate transporter. It has been reported that flies heterozygous for these Indy mutations, which lie outside the coding region, show almost a doubling of lifespan. We report that only one of the two mutants lowers mRNA levels, implying that the lifespan extension observed is not attributable to the Indy mutations themselves. Moreover, neither Indy mutation extended lifespan in female flies in any genetic background tested. In the original genetic background, only the Indy mutation associated with altered RNA expression extended lifespan in male flies. However, this effect was abolished by backcrossing into standard outbred genetic backgrounds, and was associated with an unidentified locus on the X chromosome. The original Indy line with long-lived males is infected by the cytoplasmic symbiont Wolbachia, and the longevity of Indy males disappeared after tetracycline clearance of this endosymbiont. These findings underscore the critical importance of standardisation of genetic background and of cytoplasm in genetic studies of lifespan, and show that the lifespan extension previously claimed for Indy mutants was entirely attributable to confounding variation from these two sources. In addition, we saw no effects on lifespan of expression knockdown of the Indy orthologues nac-2 and nac-3 in the nematode Caenorhabditis elegans.

  13. Cytoplasmic ATR Activation Promotes Vaccinia Virus Genome Replication

    Directory of Open Access Journals (Sweden)

    Antonio Postigo

    2017-05-01

    Full Text Available In contrast to most DNA viruses, poxviruses replicate their genomes in the cytoplasm without host involvement. We find that vaccinia virus induces cytoplasmic activation of ATR early during infection, before genome uncoating, which is unexpected because ATR plays a fundamental nuclear role in maintaining host genome integrity. ATR, RPA, INTS7, and Chk1 are recruited to cytoplasmic DNA viral factories, suggesting canonical ATR pathway activation. Consistent with this, pharmacological and RNAi-mediated inhibition of canonical ATR signaling suppresses genome replication. RPA and the sliding clamp PCNA interact with the viral polymerase E9 and are required for DNA replication. Moreover, the ATR activator TOPBP1 promotes genome replication and associates with the viral replisome component H5. Our study suggests that, in contrast to long-held beliefs, vaccinia recruits conserved components of the eukaryote DNA replication and repair machinery to amplify its genome in the host cytoplasm.

    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.

    Full Text Available This work deals with the relationship between induced abortion and mental health with a special focus on the area of political controversy. This article explores the historical background of the abortion and its legislative implications in Europe with special reference to Bosnia and Herzegovina. This work is based on etnographich, analitical and historical aproaches. It explains abortion in medical terms and analyzes the psychological effects of the abortion. This is a significant and challanging topic for those who find themselves facing the moral dilemma of whether or not to terminate a pregnancy. Problems of controversy are numerous. Is abortion a murder or not? Is fetus a person or not? When it becomes the one if ever till the birth? If abortion is not morally wrong, that doesn't mean that it's right to have an abortion. If abortion is morally wrong, that doesn't mean that it is always impermissible to have an abortion. The comon dilema is whether having an abortion is less wrong than the alternatives. These are some of the questions this paper deals with.

    This article reviews the current legal status of abortion in Australia and its implications. Australian abortion law has been a matter for the states since before Federation. In the years since Federation there have been significant reforms and changes in the abortion laws of some jurisdictions, although not all. Across Australia there are now nine sets of laws, state and Commonwealth, concerned with abortion. The test of a lawful abortion varies greatly across jurisdictions. In a number of states and territories, it is necessary to establish a serious risk to the physical or mental health of the woman if the pregnancy was to continue. In some cases, the certification of two doctors is required, particularly for abortions at later gestations. There are also physical restrictions on access, such as in South Australia and the Northern Territory where abortion must take place in a hospital. Only in the ACT has abortion been removed from the criminal law altogether. Variations in the law and restrictions arising from these are not consistent with the aims and provision of the universal, accessible health care system aspired to in Australia. There is an urgent need for overall reform and the introduction of uniformity to Australia's abortion laws, including removal of abortion from the criminal law. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Induced abortion is more frequent in Sweden than in many other Western countries. We wanted to investigate attitudes and knowledge about induced abortion among politicians responsible for healthcare in three Swedish counties. A study-specific questionnaire was sent to all 375 elected politicians in three counties; 192 (51%) responded. The politicians stated that they were knowledgeable about the Swedish abortion law. More than half did not consider themselves, in their capacity as politicians, sufficiently informed about abortion-related matters. Most politicians (72%) considered induced abortion to be primarily a 'women's rights issue' rather than an ethical one, and 54% considered 12 weeks' gestational age an adequate upper limit for induced abortion. Only about a third of the respondents were correctly informed about the number of induced abortions annually carried out in Sweden. Information and knowledge on induced abortion among Swedish county politicians seem not to be optimal. Changes aimed at reducing the current high abortion rates will probably not be easy to achieve as politicians seem to be reluctant to commit themselves on ethical issues and consider induced abortion mainly a women's rights issue.

    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.

  1. Abortions bring economic pressure to bear on hospitals.

    The current abortion controversy has serious potential economic consequences for U.S. hospitals, from boycotts and other political actions, but also because of lack of reimbursement for procedures performed on indigent women. An example was given of a threatened boycott of a private hospital in Washington state by evangelical residents and their physicians. Another example of boycott of hospital blood donations was cited. 1078, or 28.7%, of 3752 U.S. hospitals that are equipped to perform abortions do so. 90% of abortions are done by 31% of U.S. hospitals. 90% of these are 1st trimester abortions, costing $200-300. Many employer-sponsored health insurance plans pay for abortions, but Medicaid programs pay for limited numbers of abortions: all abortions for poor women in 13 states, but only those need to save the woman's life in most states. The federal government paid $62,235 for 84 abortions in 13 states in 1988. California and New York have extensive abortion programs for the poor. Hospitals keep a low profile about abortion services, declining to advertise their activity.

  2. Abortion law, policy and services in India: a critical review.

    Despite 30 years of liberal legislation, the majority of women in India still lack access to safe abortion care. This paper critically reviews the history of abortion law and policy in India since the 1960s and research on abortion service delivery. Amendments in 2002 and 2003 to the 1971 Medical Termination of Pregnancy Act, including devolution of regulation of abortion services to the district level, punitive measures to deter provision of unsafe abortions, rationalisation of physical requirements for facilities to provide early abortion, and approval of medical abortion, have all aimed to expand safe services. Proposed amendments to the MTP Act to prevent sex-selective abortions would have been unethical and violated confidentiality, and were not taken forward. Continuing problems include poor regulation of both public and private sector services, a physician-only policy that excludes mid-level providers and low registration of rural compared to urban clinics; all restrict access. Poor awareness of the law, unnecessary spousal consent requirements, contraceptive targets linked to abortion, and informal and high fees also serve as barriers. Training more providers, simplifying registration procedures, de-linking clinic and provider approval, and linking policy with up-to-date technology, research and good clinical practice are some immediate measures needed to improve women's access to safe abortion care.

    To analyze the opinion of judges and prosecutors concerning Brazilian abortion law and situations in which the abortion should be allowed. A cross-sectional study was performed with 1,493 judges and 2,614 prosecutors in Brazil between 2005 and 2006. Participants completed a structured questionnaire approaching sociodemographic characteristics, opinions about abortion law, and circumstances in which abortion is considered lawful. Bivariate and multivariate analyses of data were carried out through Poisson regression. The majority of participants (78%) found that the circumstances in which abortion is considered lawful should be broadened, or even that abortion should not be criminalized. The highest rates of pro-abortion opinions resulted from: risk to the life of the mother (84%), anencephaly (83%), severe congenital malformation of fetus (82%), and pregnancy resulting from rape (82%). Variables related to religion were strongly associated to the opinion of participants. There is a trend in considering the need of changing the current abortion law, in the sense of widening the circumstances in which abortion is considered lawful, or even toward decriminalizing abortion, regardless of the circumstances in which it takes place.

    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.

  5. The interaction between legalization of abortion and contraception in Denmark.

    Matthiessen, P C

    1979-01-01

    Trends in fertility, abortion, and contraceptive practice in Denmark were analyzed, using previously compiled official statistics; the conclusion was drawn that easy access to abortion may contribute toward a decline in contraceptive practice depending on the level of contraceptive practice in the population and on the degree of confidence the population has in available contraceptive methods. In October 1973 Denmark passed a law permitting women to obtain free abortion on demand. The number of legal abortions increased from 16,500 in 1973 to 28,000 in 1975. This marked increase was not attributable to a decline in illegal abortion since that annual number had declined from 5,000 to 1,000 prior to the passage of the 1973 abortion on demand law. The increase in abortion observed from 1973-1975 was accompanied by a marked decrease in the number of oral contraceptive cycles sold. Annual sales decreased from 3.9 million cycles to 2.6 million. It was difficult to access the factors responsible for this decline. Although IUD insertions increased during this period, the increase could not adequately compensate for the reduction in oral contraceptive sales. The decline in oral contraceptive sales occurred at about the time the negative side effects associated with the pill received widespread news coverage. Some of the decline in pill usage was probably due to fear of side effects, but abortion availability also encouraged women to be more lax about taking the pill and encouraged them to rely on less effective methods of contraception. Tables provide data for Denmark in reference to: 1) number of legal abortions and the abortion rates for 1940-1977; 2) distribution of abortions by season, 1972-1977; 3) abortion rates by maternal age, 1971-1977; 4) oral contraceptive and IUD sales for 1977-1978; and 5) number of births and estimated number of abortions and conceptions, 1960-1975.

    Full Text Available Abstract Background Unisexual vertebrates have been demonstrated to reproduce by gynogenesis, hybridogenesis, parthenogenesis, or kleptogenesis, however, it is uncertain how the reproduction mode contributes to the clonal diversity. Recently, polyploid gibel carp has been revealed to possess coexisting dual modes of unisexual gynogenesis and sexual reproduction and to have numerous various clones. Using sexual reproduction mating between clone D female and clone A male and subsequent 7 generation multiplying of unisexual gynogenesis, we have created a novel clone strain with more than several hundred millions of individuals. Here, we attempt to identify genetic background of the novel clone and to explore the significant implication for clonal diversity contribution. Methods Several nuclear genome markers and one cytoplasmic marker, the mitochondrial genome sequence, were used to identify the genetic organization of the randomly sampled individuals from different generations of the novel clone. Results Chromosome number, Cot-1 repetitive DNA banded karyotype, microsatellite patterns, AFLP profiles and transferrin alleles uniformly indicated that nuclear genome of the novel clone is identical to that of clone A, and significantly different from that of clone D. However, the cytoplasmic marker, its complete mtDNA genome sequence, is same to that of clone D, and different from that of clone A. Conclusions The present data indicate that the novel clone is a nucleo-cytoplasmic hybrid between the known clones A and D, because it originates from the offspring of gonochoristic sexual reproduction mating between clone D female and clone A male, and contains an entire nuclear genome from the paternal clone A and a mtDNA genome (cytoplasm from the maternal clone D. It is suggested to arise via androgenesis by a mechanism of ploidy doubling of clone A sperm in clone D ooplasm through inhibiting the first mitotic division.

    Chromatin is traditionally viewed as a nuclear entity that regulates gene expression and silencing. However, we recently discovered the presence of cytoplasmic chromatin fragments that pinch off from intact nuclei of primary cells during senescence, a form of terminal cell-cycle arrest associated with pro-inflammatory responses. The functional significance of chromatin in the cytoplasm is unclear. Here we show that cytoplasmic chromatin activates the innate immunity cytosolic DNA-sensing cGAS-STING (cyclic GMP-AMP synthase linked to stimulator of interferon genes) pathway, leading both to short-term inflammation to restrain activated oncogenes and to chronic inflammation that associates with tissue destruction and cancer. The cytoplasmic chromatin-cGAS-STING pathway promotes the senescence-associated secretory phenotype in primary human cells and in mice. Mice deficient in STING show impaired immuno-surveillance of oncogenic RAS and reduced tissue inflammation upon ionizing radiation. Furthermore, this pathway is activated in cancer cells, and correlates with pro-inflammatory gene expression in human cancers. Overall, our findings indicate that genomic DNA serves as a reservoir to initiate a pro-inflammatory pathway in the cytoplasm in senescence and cancer. Targeting the cytoplasmic chromatin-mediated pathway may hold promise in treating inflammation-related disorders.

    A 15-year-old girl at 18 weeks gestation by the last menstrual period presented to a rural Ugandan healthcare facility for termination of her pregnancy as a result of rape by her uncle. Skilled healthcare workers at the facility refused to provide the abortion due to fear of legal repercussions. The patient subsequently obtained an unsafe abortion by vaginal insertion of local herbs and sharp objects. She developed profuse vaginal bleeding and haemorrhagic shock. She was found to have uterine rupture and emergent hysterectomy was performed. Young and poor women are at high risk of unplanned pregnancy and subsequent mortality during pregnancy and childbirth. Unsafe abortion is a leading and entirely preventable cause of maternal mortality worldwide. Multiple barriers restrict access to safe abortions including social and moral stigma, gender-based power imbalances, inadequate contraceptive use and sexual education, high cost and poor availability, and restrictive abortion laws. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    The article focuses on the different factors and circumstances that have led to the reform of Spanish Abortion Law (1985). Judicial investigations of several abortion clinics have demonstrated that up until today there has been a widespread tendency of the clinics to practice beyond the limits established by the law. Nonetheless, the reaction of the government has not been to protect the life of the unborn. Its reaction has been, however, to cover the irregularities committed by the abortionists through the legalization of their abusive practices. Besides, the reform of the law has been inspired by elements of radical feminism. The author points out the major reasons that make this reform unconstitutional and offers alternative solutions for the protection of the mother and the unborn child.

    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.

    An exploratory study of the perceptions of 156 abortion clients in Mexico suggests that perceived quality of service was the main reason for choosing physicians while cost and anonymity were the major reasons for choosing nonphysicians. "Too young" was the most often cited reason for pregnancy termination, followed by economic situation and having too many children already. Cost was, on average, equivalent to three to four weeks minimum wage; physicians' charges were about three times higher than those of nonphysicians.

    Full Text Available Abortion is still a very popular and controversial topic in recent years. Many esteemed people in our country have confessed to abortion. The changes that had taken place through the amendment of the anti-abortion law [1] contributed to the confession of famous personalities [2]. Most of them show that it was not wrong. Most of the confessions of women who have made abortions come down to one sad conclusion: it is a decision that can not be reversed or changed. This decision imprints not only on the woman who takes her but also on the whole society. Especially since there is a solution for mothers who do not feel good to raise their child. There is even a window of life [28]. They usually work in children's homes, monasteries or hospitals. They allow anonymous leave of a child in a place that is safe for him or her. Children go to adoption and their parents are not sought. In almost allEuropethere are "windows of life". The United Nations Committee on the Rights of the Child, appealed for the elimination of "windows of life", the idea of which violates the child's right to identity and is not in accordance with the Convention on the Rights of the Child. The Committee expressed "deep concern over the lack of regulation and the increasing number of baby windows that allow for anonymous abandonment of the baby." Thus, another dilemma arises between the right to identity and the right to life. He recommends "anonymous birth" in hospitals. This is a procedure used inter alia inGermany. During childbirth, the mother remains anonymous, although her data is kept in a designated office. The child is 16 years old, if he wants to know her identity. [29

    Full Text Available Some infantile hemangiomas called in literature “minimal or arrested growth hemangiomas” or “abortive hemangiomas” are present at birth and have a proliferative component equaling less than 25% of its total surface area. Often, they are mistaken for vascular malformation. We present five patients (three girls and two boys with abortive hemangiomas diagnosed between January 2010 and December 2015 localized in acral part of the extremities. They were congenital lesions resembling precursor of hemangiomas but did not show proliferation phase. Immunohistochemical Glut-1 was performed in all of them as a way to confirm the abortive hemangioma diagnosis. The most common appearance was a reticulated erythematous patch with multiple fine telangiectasias on the surface. We remark that one of them presented a segmental patch with two different morphologies and evolutions. The proximal part showed pebbled patches of bright-red hemangioma and presented proliferation and the distal part with a reticulated network-like telangiectasia morphology remained unchanged. We detected lower half of the body preference and dorsal region involvement preference without ventral involvement. The ulceration occurred in three patients with two different degrees of severity.

  19. CONTINUOUS ABORT GAP CLEANING AT RHIC

    2004-01-01

    Since the RHIC Au-Au run in the year 2001 the 200 MHz cavity system was used at storage and a 28 MHz system during injection and acceleration. The rebucketing procedure potentially causes a higher debunching rate of heavy ion beams in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam can easily account for more than 50% of the total beam intensity. This effect is even stronger with the achieved high intensities of the RHIC Au-Au run in 2004. A beam abort at the presence of a lot of debunched beam bears the risk of magnet quenching and experimental detector damage due to uncontrolled beam losses. Thus it is desirable to avoid any accumulation of debunched beam from the beginning of each store, in particular to anticipate cases of unscheduled beam aborts due to a system failure. A combination of a fast transverse kickers and the new 2-stage copper collimator system are used to clean the abort gap continuously throughout the store with a repetition rate of 1 Hz. This report gives. an overview of the new gap cleaning procedure and the achieved performance

    Unsafe abortion is a significant cause of maternal morbidity and mortality in developing countries despite provision of adequate care and legalization of abortion. The aim of this study was to find out the contribution of unsafe abortion in maternal mortality and its other consequences. A retrospective study was carried out in the Department of Obstetrics and Gynecology in BPKIHS between 2005 April to 2008 September analyzing all the unsafe abortion related admissions. There were 70 unsafe abortion patients. Majority of them (52.8%) were of high grade. Most of them recovered but there were total 8 maternal deaths. Unsafe abortion is still a significant medical and social problem even in post legalization era of this country.
