Ethics and synthetic gametes.  

PubMed

The recent in vitro derivation of gamete-like cells from mouse embryonic stem (mES) cells is a major breakthrough and lays down several challenges, both for the further scientific investigation and for the bioethical and biolegal discourse. We refer here to these cells as gamete-like (sperm-like or oocyte-like, respectively), because at present there is still no evidence that these cells behave fully like bona fide sperm or oocytes, lacking the fundamental proof, i.e. combination with a normally derived gamete of the opposite sex to yield a normal individual. However, the results published so far do show that these cells share some defining features of gametes. We discuss these results in the light of the bioethical and legal questions that are likely to arise would the same process become possible with human embryonic stem (hES) cells. PMID:15943023

Gamete donation and parental responsibility.  

PubMed

Unlike surrogacy and cloning, reproduction via gamete donation is widely assumed to be morally unproblematic. Recently, a number of authors have argued that this assumption is mistaken: gamete donors, they claim, have parental responsibilities that they typically treat too lightly. In this paper I argue that the 'parental neglect' case against gamete donation fails. I begin by examining and rejecting the view that gamete donors have parental responsibilities; I claim that none of the current accounts of parenthood provides good reason for ascribing parenthood to gamete donors. I then argue that even if gamete donors do have parental responsibilities for 'their' children, it is not clear that they treat these responsibilities too lightly. I conclude the paper by examining the wider question of just what kind of responsibilities gamete donors might have towards the children that they have a role in creating. PMID:14552297

SACY-1 DEAD-Box Helicase Links the Somatic Control of Oocyte Meiotic Maturation to the Sperm-to-Oocyte Switch and Gamete Maintenance in Caenorhabditis elegans  

PubMed Central

In sexually reproducing animals, oocytes arrest at diplotene or diakinesis and resume meiosis (meiotic maturation) in response to hormones. In Caenorhabditis elegans, major sperm protein triggers meiotic resumption through a mechanism involving somatic G?s–adenylate cyclase signaling and soma-to-germline gap-junctional communication. Using genetic mosaic analysis, we show that the major effector of G?s–adenylate cyclase signaling, protein kinase A (PKA), is required in gonadal sheath cells for oocyte meiotic maturation and dispensable in the germ line. This result rules out a model in which cyclic nucleotides must transit through sheath-oocyte gap junctions to activate PKA in the germ line, as proposed in vertebrate systems. We conducted a genetic screen to identify regulators of oocyte meiotic maturation functioning downstream of G?s–adenylate cyclase–PKA signaling. We molecularly identified 10 regulatory loci, which include essential and nonessential factors. sacy-1, which encodes a highly conserved DEAD-box helicase, is an essential germline factor that negatively regulates meiotic maturation. SACY-1 is a multifunctional protein that establishes a mechanistic link connecting the somatic control of meiotic maturation to germline sex determination and gamete maintenance. Modulatory factors include multiple subunits of a CoREST-like complex and the TWK-1 two-pore potassium channel. These factors are not absolutely required for meiotic maturation or its negative regulation in the absence of sperm, but function cumulatively to enable somatic control of meiotic maturation. This work provides insights into the genetic control of meiotic maturation signaling in C. elegans, and the conserved factors identified here might inform analysis in other systems through either homology or analogy.

Gametic isolation in guppies (Poecilia reticulata).  

PubMed

Post-mating reproductive isolating mechanisms may be among the earliest reproductive barriers to emerge among incipient species. Trinidadian guppy, Poecilia reticulata, populations in the Caroni and Oropouche drainages in Northern Trinidad exhibit marked genetic divergence and provide an ideal system in which to search for these barriers. We inseminated virgin females with equal amounts of sperm from two males, a 'native' male from the female's own population and a 'foreign' male from the other drainage. Artificial insemination ensured that mating order and mate choice did not affect the outcome. Paternities were assigned to the resulting broods using microsatellite markers. As predicted, sperm from native males had precedence over foreign sperm. Moreover, this effect was symmetrical for both drainages. In contrast, we detected no native sperm precedence in controls, in which females received sperm from the same and another population within the same drainage. Our results show that gametic isolation can arise between geographically proximate, though genetically divergent, populations of a single species and highlight the potential role of this process in speciation.

Negotiating boundaries: Accessing donor gametes in India  

PubMed Central

Background: This paper documents how couples and providers access donor materials for conception in the Indian context and perceptions about using them. The objective is to facilitate understanding of critical issues and relevant concerns. Methods: A postal survey was conducted with a sample of 6000 gynaecologists and in-depth interviews were ­conducted with 39 gynaecologists in four cities. Results: Donor gametes are relatively more acceptable than a few years ago, especially if confidentiality can be ­maintained, though lack of availability of donor materials is sometimes an impediment to infertility treatment. Donor sperms are usually accessed from in-house or commercial sperm banks, pathology laboratories, IVF centres, ­professional donors, relatives or friends. There is scepticism about screening procedures of sperm banks. Donor eggs are usually accessed from voluntary donors, friends, relatives, egg sharing programmes, donation from other patients, advertising and commercial donors. There are several concerns regarding informed consent for using donated gametes, using ­relatives and friends gametes, the unregulated use of gametes and embryos, record keeping and documentation, ­unethical and corrupt practices and commercialisation. Conclusion: These issues need to be addressed by patients, providers and regulatory authorities by providing ­information, counselling, ensuring informed consent, addressing exploitation and commercialisation, ensuring ­monitoring, proper documentation and transparency.

[Cultural diversity in gamete and embryos donation].  

PubMed

Through gamete and embryo donation have successively emerged new ways of designing individuals who, in turn, have generated mutations in the concept of parenthood. A debate is open to the society, which often raises ideological cleavages. Indeed, donation practices mobilize the conflicting interests of donor of gametes, the recipient couple, child, whose origins are complex, although his filiation is legally clear. Its place in the family genealogy can be examined in relation to other societies, which admit plural concepts called "classificatory" kinship. They set up role partition between parents and educators. Setting anthropological perspective provides a broadening of the reflection to answer questions from the donation practices, including genealogical questions of revelation to the child of his conception, his incorporation in family and social group and the importance of compensation of donation.

Testing predictions from the male control theory of men's partner violence.  

PubMed

The aim of this study was to test predictions from the male control theory of intimate partner violence (IPV) and Johnson's [Johnson, M. P. (1995). Journal of Marriage and the Family, 57, 282-294] typology. A student sample (N?=?1,104) reported on their use of physical aggression and controlling behavior, to partners and to same-sex non-intimates. Contrary to the male control theory, women were found to be more physically aggressive to their partners than men were, and the reverse pattern was found for aggression to same-sex non-intimates. Furthermore, there were no substantial sex differences in controlling behavior, which significantly predicted physical aggression in both sexes. IPV was found to be associated with physical aggression to same-sex non-intimates, thereby demonstrating a link with aggression outside the family. Using Johnson's typology, women were more likely than men to be classed as "intimate terrorists," which was counter to earlier findings. Overall, these results do not support the male control theory of IPV. Instead, they fit the view that IPV does not have a special etiology, and is better studied within the context of other forms of aggression. PMID:23878077

Ancestor embryos: embryonic gametes and genetic parenthood.  

PubMed

The proposal for reproducing human generations in vitro raises the question to what extent parenthood is possible in embryos and to what extent human rights and interests are dependent on conscious awareness. This paper argues that the interest in not being made a parent non-consensually for the benefit of others persists throughout the lifespan of the individual human organism. We do not become genetic parents by learning that we are parents; rather, we discover (or fail to discover) an existing genetic relationship between our offspring and ourselves. The claim to genetic parenthood of an embryo used for reproduction in vitro is, if anything, clearer than the claim of the adult for whom gametes are derived via ips cells, in that an embryo's cells, unlike an adult's somatic cells, are already functionally geared to producing gametes (among other types of cell). An embryo used to make gametes that are used in reproduction is immediately and non-consensually made a genetic parent and to that extent is wronged whether or not the parent embryo survives-as some could survive-the harvesting of cells. All human individuals carry objective interests in benefits appropriate to the kind of being they are; these include the stake in not being made a parent without one's consent, whether posthumously or otherwise.

Social consequences of sleep disordered breathing on patients and their partners: a controlled national study.  

PubMed

We aimed to evaluate the total costs to patients and their partners of sleep apnoea and obesity hypoventilation syndrome (OHS) and their treatment, as this is poorly described in families. Using data from the Danish National Patient Registry and other public databases, all patients and their partners with a diagnosis of sleep apnoea (n=30,278) or OHS (n=1562) were included. They were compared with age-, sex- and community location-matched citizens at a ratio 1:4 (120,506 and 6241 control subjects, respectively). Direct and indirect costs were evaluated for patients and their partners. Sleep apnoea and OHS patients and their partners had higher rates of health-related contact, medication use and unemployment, and lower income levels. Excess yearly direct net health and foregone earnings (indirect costs) were €2174 and €7981 prior to diagnosis, and €3988 and €12,022 after diagnosis for sleep apnoea and OHS, respectively. The comparable annual mean excess health-related costs for spouses were €1965 and €2862 before diagnosis, and €2307 and €3079 after diagnosis, for sleep apnoea and OHS patients, respectively. These socioeconomic consequences were present up to 12 years before first diagnosis, and increased as the disease advanced. Sleep-disordered breathing has major socioeconomic consequences for patients and their spouses years before and after diagnosis. PMID:23563260

Relatively speaking: halachic and legal issues of gamete donation.  

PubMed

The dramatic increase of gamete donations, as a result of technological advances in assisted reproduction, has raised considerable legal and halachic issues. This article raises reader awareness about problems involved in gamete donation within Jewish law (halacha), particularly in Israel. Two core problems with gamete donation are: deciding the mother of the child (donor or birthing mother) and genetic lineage. The former is important in establishing the child's religious status and the latter for matters of consanguinity and incest. Anonymous gamete donation increases the probability of incest. Persons unaware of their biological heritage could unintentionally cohabit with a close family member and progeny of this union would be considered mamzerim. These problems may be prevented by legislation, registration, and greater openness by the donor and the intended parents of the donor conceived child. This article focuses on the halachic perspective of gamete donation. Since consanguinity is prohibited by most cultures, the implications of gamete donation are universally relevant. PMID:21877469

Kinetics of adhesion and de-adhesion of Chlamydomonas gametes.  

PubMed

In medium with low nitrogen content, vegetative strains of the unicellular biflagellate alga Chlamydomonas reinhardi form gametes. Mating type plus (mt+) and mating type minus (mt-) gametes adhere via their flagella to give aggregates in which the gametes eventually fuse to form zygotes. A quantitative assay has now been developed which measures aggregation and fusion by use of a Coulter electronic particle counter to determine loss of single gametes as they form aggregates in suspension. Determination of the rate and extent of cell fusion by microscopy agrees with the results obtained with the more rapid and convenient Coulter counter assay. By use of the assay it was found that aggregation and fusion occur at the same rate and to the same extent at 12 degrees C and 25 degrees C. Flagella from one of the mating types can specifically substitute for the corresponding live gametes; more than 70% of the gametes were aggregated and the extent of aggregation was proportional to the number of flagella added, until the ratio of cells to flagella exceeded 2. At 22 degrees C, in the flagella/gamete mixtures, adhesion was complete in less than 5 min, but at 5 to 10 min, gametes began to de-adhere from the clusters and, depending on the number of flagella added, essentially all of the gametes detached from the aggregates in 10 to 50 min. The gametes in such mixtures were fully competent to aggregate again, whereas the flagella recovered from such mixtures were shown by use of a radioactive flagella-binding assay to be inactive with fresh gametes. Inactivation of the flagella was temperature-dependent, was not catalyzed by soluble factors, and required adhesion of flagella to gametes of the opposite mating type. The potential physiological functions of the de-adhesion process are discussed. PMID:500610

Property rights in human gametes in Australia.  

PubMed

It has long been a basic tenet of the common law that there can be no property interest in human bodies or body parts. However, exceptions to the rule have been recognised from the mid-19th century and developed over time. In the early 21st century, there have been interesting developments in the common law of Australia and England, with Australian Supreme Court judges and the English Court of Appeal casting aside existing exceptions, and finding property rights in human body parts, including gametes, by relying instead on a "rational" and "logical" basis to identify property interests in human body parts.

Controlling behavior, power relations within intimate relationships and intimate partner physical and sexual violence against women in Nigeria  

PubMed Central

Background Controlling behavior is more common and can be equally or more threatening than physical or sexual violence. This study sought to determine the role of husband/partner controlling behavior and power relations within intimate relationships in the lifetime risk of physical and sexual violence in Nigeria. Methods This study used secondary data from a cross-sectional nationally-representative survey collected by face-to-face interviews from women aged 15 - 49 years in the 2008 Nigeria Demographic and Health Survey. Utilizing a stratified two-stage cluster sample design, data was collected frrm 19 216 eligible with the DHS domestic violence module, which is based on the Conflict Tactics Scale (CTS). Multivariate logistic regression analysis was used to determine the role of husband/partner controlling behavior in the risk of ever experiencing physical and sexual violence among 2877 women aged 15 - 49 years who were currently or formerly married or cohabiting with a male partner. Results Women who reported controlling behavior by husband/partner had a higher likelihood of experiencing physical violence (RR = 3.04; 95% CI: 2.50 - 3.69), and women resident in rural areas and working in low status occupations had increased likelihood of experiencing physical IPV. Controlling behavior by husband/partner was associated with higher likelihood of experiencing physical violence (RR = 4.01; 95% CI: 2.54 - 6.34). In addition, women who justified wife beating and earned more than their husband/partner were at higher likelihood of experiencing physical and sexual violence. In contrast, women who had decision-making autonomy had lower likelihood of experiencing physical and sexual violence. Conclusion Controlling behavior by husband/partner significantly increases the likelihood of physical and sexual IPV, thus acting as a precursor to violence. Findings emphasize the need to adopt a proactive integrated approach to controlling behavior and intimate partner violence within the society. PMID:21714854

Study of aneuploidy and DNA fragmentation in gametes of patients with severe teratozoospermia.  

PubMed

This study investigated meiotic segregation in spermatozoa to determine if severe teratozoospermia should prevent the use of intracytoplasmic sperm injection (ICSI) because of the high production of gametes with chromosomal aneuploidies and analysed DNA fragmentation in gametes from the same semen to determine if DNA integrity was worse in patients with severe teratozoospermia. Sperm samples from 12 infertile patients were studied by fluorescence in-situ hybridization for chromosomes X, Y, 13, 18 and 21 and by TdT (terminal deoxynucleotidyl transferase)-mediated dUDP nick-end labelling. Four patients with a majority of macrocephalic forms with multiple flagella had more than 99% spermatozoa with abnormal chromosomal content. The other patients (globozoospermia or other abnormalities concerning sperm heads) had no increased aneuploidy or a slightly significant increase (P<0.05). The rate of DNA fragmentation was significantly higher in infertile patients than in the controls (P<0.001; 14.3% versus 1.20%, respectively) but presented important variability. Therefore, ICSI should not be attempted if men have macrocephalic gametes with multiple flagella but morphology is not always a good predictor of chromosomal content, depending upon the kind of teratozoospermia. Evaluation of the rate of aneuploidy and DNA fragmentation in gametes of patients with severe teratozoospermia is recommended. PMID:21233018

Cleaner wrasse prefer client mucus: support for partner control mechanisms in cleaning interactions.  

PubMed Central

Recent studies on cleaning behaviour suggest that there are conflicts between cleaners and their clients over what cleaners eat. The diet of cleaners usually contains ectoparasites and some client tissue. It is unclear, however, whether cleaners prefer client tissue over ectoparasites or whether they include client tissue in their diet only when searching for parasites alone is not profitable. To distinguish between these two hypotheses, we trained cleaner fish Labroides dimidiatus to feed from plates and offered them client mucus from the parrotfish Chlorurus sordidus, parasitic monogenean flatworms, parasitic gnathiid isopods and boiled flour glue as a control. We found that cleaners ate more mucus and monogeneans than gnathiids, with gnathiids eaten slightly more often than the control substance. Because gnathiids are the most abundant ectoparasites, our results suggest a potential for conflict between cleaners and clients over what the cleaner should eat, and support studies emphasizing the importance of partner control in keeping cleaning interactions mutualistic.

Towards storage of cells and gametes in dry form.  

PubMed

We review published data on cell/gamete lyophilization. Most studies have utilized the same established protocols for cryopreservation (storage in liquid nitrogen) as for cell lyophilization (dehydration of frozen samples by water sublimation). Surveying natural lyoprotectants, we suggest trehalose and late embryogenesis abundant (LEA) proteins as ideal candidates for the reversible desiccation of mammalian cells/gametes. We find that despite the numerous water subtraction techniques, scientists have relied almost exclusively on lyophilization. There is thus room for improvement in both medium formulation and water subtraction strategies for dry cell/gamete storage. We believe the development of dry processing protocols for use in biobanks of cells/gametes, at reduced cost and with minimal carbon footprint, is within our grasp. PMID:24169600

SOCS1, a novel interaction partner of p53 controlling oncogene-induced senescence  

PubMed Central

Members of the signal transducers and activators of transcription (STATs) family of proteins, which connect cytokine signaling to activation of transcription, are frequently activated in human cancers. Suppressors of cytokine signaling (SOCS) are transcriptional targets of activated STAT proteins that negatively control STAT signaling. SOCS1 expression is silenced in multiple human cancers suggesting a tumor suppressor role for this protein. However, SOCS1 not only regulates STAT signaling but can also localize to the nucleus and directly interact with the p53 tumor suppressor through its central SH2 domain. Furthermore, SOCS1 contributes to p53 activation and phosphorylation on serine 15 by forming a ternary complex with ATM or ATR. Through this mechanism SOCS1 regulates the process of oncogene-induced senescence, which is a very important tumor suppressor response. A mutant SOCS1 lacking the SOCS box cannot interact with ATM/ATR, stimulate p53 or induce the senescence phenotype, suggesting that the SOCS box recruits DNA damage activated kinases to its interaction partners bound to its SH2 domain. Proteomic analysis of SOCS1 interaction partners revealed other potential targets of SOCS1 in the DNA damage response. These newly discovered functions of SOCS1 help to explain the increased susceptibility of Socs1 null mice to develop cancer as well as their propensity to develop autoimmune diseases. Consistently, we found that mice lacking SOCS1 displayed defects in the regulation of p53 target genes including Mdm2, Pmp22, PUMA and Gadd45a. The involvement of SOCS1 in p53 activation and the DNA damage response defines a novel tumor suppressor pathway and intervention point for future cancer therapeutics. PMID:20622265

Partner-Assisted Emotional Disclosure for Patients with GI Cancer: Results from a Randomized Controlled Trial  

PubMed Central

Background For patients with cancer who are married or in an intimate relationship, their relationships with their partners play a critical role in their adaptation to their illness. However, cancer patients and their partners often have difficulty in talking with each other about their cancer-related concerns. Difficulties in communication may ultimately compromise both the patient-partner relationship and the patient's psychological adjustment. The present study tested the efficacy of a novel partner-assisted emotional disclosure intervention in a sample of patients with gastrointestinal (GI) cancer. Methods 130 patients with GI cancer and their partners were randomly assigned to receive four sessions of either partner-assisted emotional disclosure or a couples cancer education/support intervention. Patients and partners completed measures of relationship quality, intimacy with their partner, and psychological distress before randomization and at the end of the intervention sessions. Data were analyzed using multilevel modeling. Results Compared to an education/support condition, the partner-assisted emotional disclosure condition led to improvements in relationship quality and intimacy for couples in which the patient initially reported higher levels of holding back from discussing cancer-related concerns. Conclusions Partner-assisted emotional disclosure is a novel intervention that builds on both the private emotional disclosure and the cognitive-behavioral marital literature. The results of this study suggest that this intervention may be beneficial for couples in which the patient tends to hold back from discussing concerns. Future research on methods of enhancing the effects of partner-assisted emotional disclosure is warranted. PMID:19731357

Cultural Challenges Faced by American Mission Control Personnel Working with International Partners  

NASA Technical Reports Server (NTRS)

Operating the International Space Station (ISS) involves an indefinite, continuous series of long-duration international missions, and this requires an unprecedented degree of cooperation across multiple sites, organizations, and nations. Both junior and senior mission control personnel have had to find ways to address the cultural challenges inherent in such work, but neither have had systematic training in how to do so. The goals of this study were to identify and evaluate the major cultural challenges faced by ISS mission control personnel and to highlight the approaches that they have found most effective to surmount these challenges. We pay particular attention to the approaches successfully employed by the senior personnel and the training needs identified by the junior personnel. We also evaluate the extent to which the identified approaches and needs are consistent across the two samples. METHODS: Participants included a sample of 14 senior ISS flight controllers and a contrasting sample of 12 more junior controllers. All participants were mission operations specialists chosen on the basis of having worked extensively with international partners. Data were collected using a semi-structured qualitative interview and content analyzed using an iterative process with multiple coders and consensus meetings to resolve discrepancies. RESULTS: The senior respondents had substantial consensus on several cultural challenges and on key strategies for dealing with them, and they offered a wide range of specific tactics for implementing these strategies. Data from the junior respondents will be presented for the first time at the meeting. DISCUSSION: Although specific to American ISS personnel, our results are consistent with recent management, cultural, and aerospace research on other populations. We aim to use our results to improve training for current and future mission control personnel working in international or multicultural mission operations teams.

Oxidative stress-induced assembly of PML nuclear bodies controls sumoylation of partner proteins  

PubMed Central

The promyelocytic leukemia (PML) protein organizes PML nuclear bodies (NBs), which are stress-responsive domains where many partner proteins accumulate. Here, we clarify the basis for NB formation and identify stress-induced partner sumoylation as the primary NB function. NB nucleation does not rely primarily on intermolecular interactions between the PML SUMO-interacting motif (SIM) and SUMO, but instead results from oxidation-mediated PML multimerization. Oxidized PML spherical meshes recruit UBC9, which enhances PML sumoylation, allow partner recruitment through SIM interactions, and ultimately enhance partner sumoylation. Intermolecular SUMO–SIM interactions then enforce partner sequestration within the NB inner core. Accordingly, oxidative stress enhances NB formation and global sumoylation in vivo. Some NB-associated sumoylated partners also become polyubiquitinated by RNF4, precipitating their proteasomal degradation. As several partners are protein-modifying enzymes, NBs could act as sensors that facilitate and confer oxidative stress sensitivity not only to sumoylation but also to other post-translational modifications, thereby explaining alterations of stress response upon PML or NB loss.

Strategies for locating the female gamete: the importance of measuring sperm trajectories in three spatial dimensions.  

PubMed

The spermatozoon must find its female gamete partner and deliver its genetic material to generate a new individual. This requires that the spermatozoon be motile and endowed with sophisticated swimming strategies to locate the oocyte. A common strategy is chemotaxis, in which spermatozoa detect and follow a gradient of chemical signals released by the egg and its associated structures. Decoding the female gamete's positional information is a process that spermatozoa undergo in a three-dimensional (3D) space; however, due to their speed and small size, this process has been studied almost exclusively in spermatozoa restricted to swimming in two dimensions (2D). This review examines the relationship between the mechanics of sperm propulsion and the physiological function of these cells in 3D. It also considers whether it is possible to derive all the 3D sperm swimming characteristics by extrapolating from 2D measurements. It is concluded that full insight into flagellar beat dynamics, swimming paths and chemotaxis under physiological conditions will eventually require quantitative imaging of flagellar form, ion flux changes, cell trajectories and modelling of free-swimming spermatozoa in 3D.

Gamete evolution and sperm numbers: sperm competition versus sperm limitation.  

PubMed

Both gamete competition and gamete limitation can generate anisogamy from ancestral isogamy, and both sperm competition (SC) and sperm limitation (SL) can increase sperm numbers. Here, we compare the marginal benefits due to these two components at any given population level of sperm production using the risk and intensity models in sperm economics. We show quite generally for the intensity model (where N males compete for each set of eggs) that however severe the degree of SL, if there is at least one competitor for fertilization (N - 1 ? 1), the marginal gains through SC exceed those for SL, provided that the relationship between the probability of fertilization (F) and increasing sperm numbers (x) is a concave function. In the risk model, as fertility F increases from 0 to 1.0, the threshold SC risk (the probability q that two males compete for fertilization) for SC to be the dominant force drops from 1.0 to 0. The gamete competition and gamete limitation theories for the evolution of anisogamy rely on very similar considerations: our results imply that gamete limitation could dominate only if ancestral reproduction took place in highly isolated, small spawning groups.

Genetic generations: artificial gametes and the embryos produced with them.  

PubMed

Certain interventions now permit the derivation of mammalian gametes from stem cells cultivated from either somatic cells or embryos. These gametes can be used in an indefinite cycle of conception in vitro, gamete derivation, conception in vitro, and so on, producing genetic generations that live only in vitro. One commentator has described this prospect for human beings as eugenics, insofar as it would allow for the selection and development of certain traits in human beings. This commentary not only offers this topic for discussion, it also wades into the ethical fray over the practice. Several possible lines of objection can be raised against this practice, but these accounts are by and large insufficient as an ethical analysis of this possible, future way of conceiving human children.

Partner notification  

PubMed Central

Partner notification is an essential part of case management for sexually transmitted infections. Done correctly it reduces persistent or recurrent infection in the index patient, identifies previously undiagnosed infections, and may thus contribute to reduced transmission in the population. The effectiveness of patient referral of partners can be enhanced through the provision of written information and easy access to tests and medication. A recent systematic review of partner notification found that enhanced partner therapy (helping get treatment to partners more rapidly) reduced re-infection in the index case by almost 30% compared with simple patient referral. Provider referral, where the healthcare worker contacts partners directly, can also be effective, and provides an important service for patients who are wary of informing partners themselves. Partner notification services should be available for all patients found to have a sexually transmitted infection, whether the diagnosis is made in specialist settings, or in primary or community-based care. For patients with HIV, partner notification should be addressed when the infection is first diagnosed and revisited for subsequent partners. Access to specialist partner notification services is an important part of any sexual healthcare system. The professional competencies required to undertake partner notification have now been clearly defined. PMID:24966787

Stem cells to gametes: how far should we go?

Murine embryonic stem cells have recently been shown to be capable of differentiating in vitro into oocytes or sperm. Should these findings be duplicated using human embryonic stem cells, this would raise a number of social and ethical concerns, some specific to these particular developments, others shared with other aspects of stem cell research. This review outlines the properties of stem cells and their conversion to gametes. Concerns raised include embryo destruction, quality of gametes derived in this way, possibility for children with two male biological parents, movement towards germ line gene therapy and 'designer babies', and the future impacts on health service provisions. It is important that public discussion of some of these issues should take place. PMID:17454202

Segregation for Sexual Seed Production in Paspalum as Directed by Male Gametes of Apomictic Triploid Plants  

PubMed Central

Background and Aims Gametophytic apomixis is regularly associated with polyploidy. It has been hypothesized that apomixis is not present in diploid plants because of a pleiotropic lethal effect associated with monoploid gametes. Rare apomictic triploid plants for Paspalum notatum and P. simplex, which usually have sexual diploid and apomictic tetraploid races, were acquired. These triploids normally produce male gametes through meiosis with a range of chromosome numbers from monoploid (n = 10) to diploid (n = 20). The patterns of apomixis transmission in Paspalum were investigated in relation to the ploidy levels of gametes. Methods Intraspecific crosses were made between sexual diploid, triploid and tetraploid plants as female parents and apomictic triploid plants as male parents. Apomictic progeny were identified by using molecular markers completely linked to apomixis and the analysis of mature embryo sacs. The chromosome number of the male gamete was inferred from chromosome counts of each progeny. Key Results The chromosome numbers of the progeny indicated that the chromosome input of male gametes depended on the chromosome number of the female gamete. The apomictic trait was not transmitted through monoploid gametes, at least when the progeny was diploid. Diploid or near-diploid gametes transmitted apomixis at very low rates. Conclusions Since male monoploid gametes usually failed to form polyploid progenies, for example triploids after 4x × 3x crosses, it was not possible to determine whether apomixis could segregate in polyploid progenies by means of monoploid gametes.

Gametic embryogenesis and haploid technology as valuable support to plant breeding.  

PubMed

Plant breeding is focused on continuously increasing crop production to meet the needs of an ever-growing world population, improving food quality to ensure a long and healthy life and address the problems of global warming and environment pollution, together with the challenges of developing novel sources of biofuels. The breeders' search for novel genetic combinations, with which to select plants with improved traits to satisfy both farmers and consumers, is endless. About half of the dramatic increase in crop yield obtained in the second half of the last century has been achieved thanks to the results of genetic improvement, while the residual advance has been due to the enhanced management techniques (pest and disease control, fertilization, and irrigation). Biotechnologies provide powerful tools for plant breeding, and among these ones, tissue culture, particularly haploid and doubled haploid technology, can effectively help to select superior plants. In fact, haploids (Hs), which are plants with gametophytic chromosome number, and doubled haploids (DHs), which are haploids that have undergone chromosome duplication, represent a particularly attractive biotechnological method to accelerate plant breeding. Currently, haploid technology, making possible through gametic embryogenesis the single-step development of complete homozygous lines from heterozygous parents, has already had a huge impact on agricultural systems of many agronomically important crops, representing an integral part in their improvement programmes. The aim of this review was to provide some background, recent advances, and future prospective on the employment of haploid technology through gametic embryogenesis as a powerful tool to support plant breeding.

An mt+ gamete-specific nuclease that targets mt? chloroplasts during sexual reproduction in C. reinhardtii  

PubMed Central

Although the active digestion of mating-type minus (mt?) chloroplast DNA (cpDNA) in young zygotes is considered to be the basis for the uniparental inheritance of cpDNA in Chlamydomonas reinhardtii, little is known about the underlying molecular mechanism. One model of active digestion proposes that nucleases are either synthesized or activated to digest mt? cpDNA. We used a native-PAGE/in gelo assay to investigate nuclease activities in chloroplasts from young zygotes, and identified a novel Ca2+-dependent nuclease activity. The timing of activation (?60–90 min after mating) and the localization of the nuclease activity (in mt? chloroplasts) coincided with the active digestion of mt? cpDNA. Furthermore, the activity of the nuclease was coregulated with the maturation of mating-type plus (mt+) gametes, which would enable the efficient digestion of mt? cpDNA. Based on these observations, we propose that the nuclease (designated as Mt+-specific DNase, MDN) is a developmentally controlled nuclease that is activated in mt+ gametes and participates in the destruction of mt? cpDNA in young zygotes, thereby ensuring uniparental inheritance of chloroplast traits.

Historical background of gamete and embryo culture.  

PubMed

The first tissue culture media were developed nearly 150 years ago by Ludwig and Ringer. These were simple salt solutions, which were initially based on the chemical properties of blood serum. The second generation of culture media was developed more than a century later, in the 1970s, aiming to mimic the reproductive environment. In the 1990s, simplex optimization was used to design the third group of media, to some extent ignoring existing formulations and principles. Simultaneous with the development of culture media, it became evident that it was necessary to carefully control the culture conditions, including temperature, pH, osmolarity, and air quality. Equally important was the development of instruments and tools specifically designed for cell tissue culture such as the inverted microscope, the incubator, the Petri dish, sterile plasticware, the laminar flow cabinet, and air filtration equipment.

A controlled trial of Partners in Dementia Care: veteran outcomes after six and twelve months  

PubMed Central

Introduction “Partners in Dementia Care” (PDC) tested the effectiveness of a care-coordination program integrating healthcare and community services and supporting veterans with dementia and their caregivers. Delivered via partnerships between Veterans Affairs medical centers and Alzheimer’s Association chapters, PDC targeted both patients and caregivers, distinguishing it from many non-pharmacological interventions. Hypotheses posited PDC would improve five veteran self-reported outcomes: 1) unmet need, 2) embarrassment about memory problems, 3) isolation, 4) relationship strain and 5) depression. Greater impact was expected for more impaired veterans. A unique feature was self-reported research data collected from veterans with dementia. Methods and Findings Five matched communities were study sites. Two randomly selected sites received PDC for 12 months; comparison sites received usual care. Three structured telephone interviews were completed every 6 months with veterans who could participate. Results Of 508 consenting veterans, 333 (65.6%) completed baseline interviews. Among those who completed baseline interviews, 263 (79.0%) completed 6-month follow-ups and 194 (58.3%) completed 12-month follow-ups. Regression analyses showed PDC veterans had significantly less adverse outcomes than those receiving usual care, particularly for more impaired veterans after 6 months, including reduced relationship strain (B?=??0.09; p?=?0.05), depression (B?=??0.10; p?=?0.03), and unmet need (B?=??0.28; p?=?0.02; and B?=??0.52; p?=?0.08). PDC veterans also had less embarrassment about memory problems (B?=??0.24; p?=?0.08). At 12 months, more impaired veterans had further reductions in unmet need (B?=??0.96; p?

The gametic synapse: RNA transfer to the bovine oocyte.  

PubMed

Even after several decades of quiescent storage in the ovary, the female germ cell is capable of reinitiating transcription to build the reserves that are essential to support early embryonic development. In the current model of mammalian oogenesis, there exists bilateral communication between the gamete and the surrounding cells that is limited to paracrine signaling and direct transfer of small molecules via gap junctions existing at the end of the somatic cells' projections that are in contact with the oolemma. The purpose of this work was to explore the role of cumulus cell projections as a means of conductance of large molecules, including RNA, to the mammalian oocyte. By studying nascent RNA with confocal and transmission electron microscopy in combination with transcript detection, we show that the somatic cells surrounding the fully grown bovine oocyte contribute to the maternal reserves by actively transferring large cargo, including mRNA and long noncoding RNA. This occurrence was further demonstrated by the reconstruction of cumulus-oocyte complexes with transfected cumulus cells transferring a synthetic transcript. We propose selective transfer of transcripts occurs, the delivery of which is supported by a remarkable synapselike vesicular trafficking connection between the cumulus cells and the gamete. This unexpected exogenous contribution to the maternal stores offers a new perspective on the determinants of female fertility. PMID:25143353

Soft targets or partners in health? Retail pharmacies and their role in Tanzania's malaria control program.  

PubMed

The retail sector has been at the center of recent policy debates concerning its role in malaria control programs in Africa. This article closely examines the perspectives of owners and managers of retail pharmacies and drug shops in Dar es Salaam, toward the dominant public health discourse and practices surrounding the deployment of artemisinin-based combination therapy (ACT) as a way forward in malaria control. Drawing on fieldwork conducted between May-August 2007, and July-August 2009, involving in-depth interviews and participant observation in pharmacies and drug shops in Dar es Salaam, the article describes the social realities facing people who manage retail pharmacies, the nature of their interactions with customers, the kinds of antimalarials they sell, and their perspective on how the new malaria treatment guidelines have affected their business. Findings suggest that for most pharmacy owners and managers, it is 'business as usual' concerning the sale of conventional antimalarials, with a majority reporting that the introduction of ACT in public health facilities had not negatively affected their business. Implications of the research findings are examined in the context of proposed interventions to make pharmacy owners and managers more socially responsible and adhere to government health regulations. The article makes a case for actively involving pharmacy owners and managers in decision making processes surrounding the implementation of new treatment guidelines, and training programs that have an impact on their business, social responsibility, and community health. In considering regulatory interventions, health planners must explicitly address the concern that retail pharmacies fill an important role in the country's health care system, and that the complex nexus that drives the global pharmaceutical market often governs their operations at the local level.

Oak Ridge National Laboratory Radiation Control Program - Partners in Site Restoration  

SciTech Connect

In 1998, the U.S. Department of Energy (DOE) awarded the Management and Integration (M&I) contract for all five of the Oak Ridge Operations (ORO) facilities to Bechtel Jacobs Company LLC (BJC). At Oak Ridge National Laboratory (ORNL), a world renowned national laboratory and research and development facility, the BJC mission involves executing the DOE Environmental Management (EM) program. In addition to BJC's M&I contract, UT-Battelle, LLC, a not-for-profit company, is the Management and Operating (M&O) contractor for DOE on the ORNL site. As part of ORNL's EM program, legacy inactive facilities (i.e., reactors, nuclear material research facilities, burial grounds, and underground storage tanks) are transferred to BJC and are designated as remediation, decontamination and decommissioning (D&D), or long-term surveillance and maintenance (S&M) facilities. Facilities operated by both UT-Battelle and BJC are interspersed throughout the site and are usually in close proximity. Both UT-Battelle and BJC have DOE-approved Radiation Protection Programs established in accordance with 10 CFR 835. The BJC Radiological Control (RADCON) Program adapts to the M&I framework and is comprised of a combination of subcontracted program responsibilities with BJC oversight. This paper focuses on the successes and challenges of executing the BJC RADCON Program for BJC's ORNL Project through a joint M&I contractor relationship, while maintaining a positive working relationship and partnership with UT-Battelle's Radiation Protection organization.

2The role of controlling behaviour in intimate partner violence and its health effects: a population based study from rural Vietnam  

PubMed Central

Background Studies in North America and other high-income regions support the distinction between extreme "intimate terrorism" and occasional "situational couple violence", defined conceptually in terms of the presence or absence of controlling behaviour in the violent member of the couple. Relatively little research has been conducted on the different forms intimate partner violence may take in low-income countries. The aim of this study was to investigate whether these expressions of intimate partner violence in one low-income country, Vietnam, adhere to patterns observed in western industrialised countries as well as to investigate the resulting health effects. Methods This cross-sectional study collected structured interview data from 883 married women aged 17–60, using the Women's Health and Life Experiences questionnaire developed by WHO. Intimate partner violence was assessed by past-year experience of physical or sexual violence and control tactics were assessed using six items combined into a scale. Three different health parameters constituted the dependent variables. Bi- and multivariate analyses, including effect modification analyses, were performed. Results Of the participants, 81 (9.2%) had been exposed to physical or sexual violence during the past 12 months; of these, 26 (32.1%) had been subjected to one or more controlling behaviours by their partners. The risk of ill health associated with combined exposure was elevated eight to 15 times, compared to a two-fourfold risk increase after exposure to only one of the behaviours, i.e. violent acts or control tactics. Conclusion Physical or sexual violence combined with control tactics acted synergistically to worsen health in rural Vietnamese women. The occurrence of such violence calls for altered policies, increased research and implementation of preventive and curative strategies. The unacceptability of intimate partner violence as a part of normal Vietnamese family life must be recognised in the general debate. PMID:19442288

Tipping and mating-structure activation induced in Chlamydomonas gametes by flagellar membrane antisera  

PubMed Central

Antisera raised against vegetative and gametic flagella of Chlamydomonas reinhardi have been used to probe dynamic properties of the flagellar membranes. The antisera, which agglutinate cells via their flagella, associate with antigens that are present on both vegetative and gametic membranes and on membranes of both mating types (mt+ and mt-). Gametic cells respond to antibody presentation very differently from vegetative cells, mobilizing even high concentrations of antibody towards the flagellar tips; the possibility is discussed that such "tipping" ability reflects a differentiated gametic property relevant to sexual agglutinability. Gametic cells also respond to antibody agglutination by activating their mating structures, the mt+ reaction involving a rapid polymerization of microfilaments. Several impotent mt+ mutant strains that fail to agglutinate sexually are also activated by the antisera and procede to form zygotes with normal mt- gametes. Fusion does not occur between activated cells of like mating type. Monovalent (Fab) preparations of the antibody fail to activate mt+ gametes, suggesting that the cross-linking properties of the antisera are essential for their ability to mimic, or bypass, sexual agglutination.

The Exercising Together Project: Design and recruitment for a randomized, controlled trial to determine the benefits of partnered strength training for couples coping with prostate cancer  

PubMed Central

Prostate cancer can threaten quality of life for the patient and his spouse and the quality of his marital relationship. The purpose of our study is to evaluate the effects of “Exercising Together” – a partnered strength training program for married couples coping with prostate cancer – on the physical and emotional health of prostate cancer survivors (PCS) and their spouses and on marital quality. We are conducting a 6-month randomized controlled trial with two groups: 1) Exercising Together - a progressive, supervised strength training program and 2) a usual care control condition. The primary aims of this exploratory study are to: 1) Determine the effect of partnered strength training on physical and emotional health (muscle strength, physical function, body composition and self-report physical and mental health) in PCS, 2) Determine the effect of partnered strength training on physical and emotional health in spouses and 3) Explore the effect of partnered strength training on marital quality (incongruence, communication, relationship quality, intimacy) of the PCS and spouse. Target accrual has been met in this study with 64 couples enrolled and randomized to exercise (n=32) or usual care (n=32) groups. This study is the first to examine the feasibility of this exercise format in both the chronically ill patient and spouse and explore benefits at the individual and couple level. PMID:22101224

Delayed childbearing: determining responsibilities for prime gamete quality.  

PubMed

Delayed parenting affects fertility in women and in men, and cryopreservation of oocytes and sperm is becoming the latest trend as a solution for those who want or need to postpone procreation, in an attempt to avoid the damage medical conditions or time itself produces in gametes. Although "social freezing" is considered legitimate, its ethical and social aspects are in need of an overdue medical, public and legal debate. Assisted reproduction and cryopreservation, in combination with womb outsourcing, have opened the door to biological ectogenesis and the subsequent question of whether delayed childbearing means we should formally separate procreation from sexual activity. This article briefly summarizes what cryotechniques are capable of presently and in the near future, to separate fact from fiction. It names the implications for and discusses the practically virgin subject of the underlying responsibilities of delayed parenting techniques towards the child-to-be-not only the unborn but also the not-yet-conceived child. Considering the medical, economic, legal and social consequences of these rapidly growing developments in reproduction, several reasons point at the need to formally separate procreation from sexual activity, specifying responsibilities in the first while respecting personal choice in the second.

Artificial gametes and the ethics of unwitting parenthood.  

PubMed

In this paper, we explore the ethical and legal implications of a hypothetical use of artificial gametes (AGs): that of taking a person's cells, converting them to AGs and using them in reproduction-without that person's knowledge or consent. We note the common reliance on genetic understandings of parenthood in the law and suggest that injustices may arise if unwitting genetic parents are sued for child support. We draw parallels between the hypothetical use of AGs to facilitate unwitting parenthood and real examples of unwitting parenthood following cases of sperm theft. We also look at the harm that might be caused by becoming a genetic parent, independently of financial obligations, and ask whether such harm should be understood in terms of theft of property. These examples help to highlight some of the current and prospective difficulties for the regulation of genetic and legal parenthood, and show how existing regulatory assumptions are likely to be further challenged by the development of AGs. We conclude by suggesting that the reliance on genetic connections to generate parental responsibility (financial or otherwise) for offspring is flawed and that alternative ways of establishing parental responsibility should be considered.

Imprinting Capacity of Gamete Lineages in Caenorhabditis elegans  

PubMed Central

We have observed a gamete-of-origin imprinting effect in C. elegans using a set of GFP reporter transgenes. From a single progenitor line carrying an extrachromosomal unc-54::gfp transgene array, we generated three independent autosomal integrations of the unc-54::gfp transgene. The progenitor line, two of its three integrated derivatives, and a nonrelated unc-119:gfp transgene exhibit an imprinting effect: single-generation transmission of these transgenes through the male germline results in ?1.5- to 2.0-fold greater expression than transmission through the female germline. There is a detectable resetting of the imprint after passage through the opposite germline for a single generation, indicating that the imprinted status of the transgenes is reversible. In cases where the transgene is maintained in either the oocyte lineage or sperm lineage for multiple, consecutive generations, a full reset requires passage through the opposite germline for several generations. Taken together, our results indicate that C. elegans has the ability to imprint chromosomes and that differences in the cell and/or molecular biology of oogenesis and spermatogenesis are manifest in an imprint that can persist in both somatic and germline gene expression for multiple generations.

The Armadillo repeat protein PF16 is essential for flagellar structure and function in Plasmodium male gametes.  

PubMed

Malaria, caused by the apicomplexan parasite Plasmodium, threatens 40% of the world's population. Transmission between vertebrate and insect hosts depends on the sexual stages of the life-cycle. The male gamete of Plasmodium parasite is the only developmental stage that possesses a flagellum. Very little is known about the identity or function of proteins in the parasite's flagellar biology. Here, we characterise a Plasmodium PF16 homologue using reverse genetics in the mouse malaria parasite Plasmodium berghei. PF16 is a conserved Armadillo-repeat protein that regulates flagellar structure and motility in organisms as diverse as green algae and mice. We show that P. berghei PF16 is expressed in the male gamete flagellum, where it plays a crucial role maintaining the correct microtubule structure in the central apparatus of the axoneme as studied by electron microscopy. Disruption of the PF16 gene results in abnormal flagellar movement and reduced fertility, but does not lead to complete sterility, unlike pf16 mutations in other organisms. Using homology modelling, bioinformatics analysis and complementation studies in Chlamydomonas, we show that some regions of the PF16 protein are highly conserved across all eukaryotes, whereas other regions may have species-specific functions. PF16 is the first ARM-repeat protein characterised in the malaria parasite genus Plasmodium and this study opens up a novel model for analysis of Plasmodium flagellar biology that may provide unique insights into an ancient organelle and suggest novel intervention strategies to control the malaria parasite.

Neuronal peptides induce oocyte maturation and gamete spawning of sea cucumber, Apostichopus japonicus.  

PubMed

Extracts prepared from tissues containing buccal ring nerve or longitudinal radial nerve of sea cucumber induce oocyte maturation and ovulation from ovarian tissues. We purified two small peptides, a pentapeptide and a heptapeptide, from the buccal tissues of Japanese common sea cucumber, Apostichopus japonicas. Both peptides induced oocyte maturation and gamete spawning. The pentapeptide was identified as NGIWYamide. This peptide induced in vitro germinal vesicle breakdown and ovulation of fully-grown oocytes at less than 1 pM and in vivo spawning at 10 nM. A synthetic derivative of the pentapeptide, NGLWYamide, was 10-100 times more potent compared to the natural NGIWYamide. The heptapeptide was less potent, inducing ovulation at 1 muM. NGIWYamide and NGLWYamide induced a characteristic spawning behavior when injected into sexually matured individuals. Mature eggs artificially spawned were fertilized, and developed normally and metamorphosed into young sea cucumbers. The details of the production and the mechanism of action of NGIWYamide are still unclear, but the high biopotency of the peptide will aid understanding of the neuronal and hormonal control of reproduction of sea cucumber.

The meaning of synthetic gametes for gay and lesbian people and bioethics too.  

PubMed

Some commentators indirectly challenge the ethics of using synthetic gametes as a way for same-sex couples to have children with shared genetics. These commentators typically impose a moral burden of proof on same-sex couples they do not impose on opposite-sex couples in terms of their eligibility to have children. Other commentators directly raise objections to parenthood by same-sex couples on the grounds that it compromises the rights and/or welfare of children. Ironically, the prospect of synthetic gametes neutralises certain of these objections, insofar as they would ensure that children have parents whom they can know as their genetic parents, which outcome is not always possible when same-sex couples involve third parties as the source of gametes or embryos. Not all commentators in bioethics throw the use of synthetic gametes into doubt as far as same-sex couples are concerned, but even these commentators put parenting by gay men and lesbians at the conclusion of an argument rather than presupposing parental legitimacy from the outset. Synthetic gametes do raise questions of ethics in regard to parenthood for gay men and lesbians, but these are largely questions of access and equity, not questions of parental fitness and/or child welfare.

Gametes or organs? How should we legally classify ovaries used for transplantation in the USA?  

PubMed Central

Ovarian tissue transplantation is an experimental procedure that can be used to treat both infertility and premature menopause. Working within the current legal framework in the USA, I examine whether ovarian tissue should be legally treated like gametes or organs in the case of ovarian tissue transplantation between two women. One option is to base classification upon its intended use: ovarian tissue used to treat infertility would be classified like gametes, and ovarian tissue used to treat premature menopause would be classified like organs. In the end, however, I argue that this approach will not work because it engenders too many legal, cultural and logistical concerns and that, at least for the near future, we should treat ovarian tissue like gametes.

Reducing HIV and partner violence risk among women with criminal justice system involvement: A randomized controlled trial of two Motivational Interviewing-based interventions  

PubMed Central

Women with histories of incarceration show high levels of risk for HIV and intimate partner violence (IPV). This randomized controlled trial with women at risk for HIV who had recent criminal justice system involvement (n=530) evaluated two interventions based on Motivational Interviewing to reduce either HIV risk or HIV and IPV risk. Baseline and 3, 6, and 9-month follow-up assessments measured unprotected intercourse, needle sharing, and IPV. Generalized estimating equations revealed that the intervention groups had significant decreases in unprotected intercourse and needle sharing, and significantly greater reductions in the odds and incidence rates of unprotected intercourse compared to the control group. No significant differences were found in changes in IPV over time between the HIV and IPV group and the control group. Motivational Interviewing-based HIV prevention interventions delivered by county health department staff appear helpful in reducing HIV risk behavior for this population. PMID:18636325

Spawning of Starfish: Action of Gamete-Shedding Substance Obtained from Radial Nerves  

Microsoft Academic Search

An extract of the radial nerves of the starfish, Asterias amurensis, acts on the ovary in two ways: it induces meiosis and brings on spawning. Contraction of the gonadal wall, the driving force for spawning, does not happen until this gamete-shedding substance acts to liberate the eggs that adhere to each other or to the inner surface of the gonadal

The maternal cytoplasmic environment may be involved in the viability selection of gametes and zygotes  

PubMed Central

Segregation distortion is the phenomenon whereby the observed genotypic frequencies of a locus fall outside the expected Mendelian segregation ratio, and it is increasingly recognised as a potentially powerful evolutionary force. The main reason for segregation distortion is a difference in the viability of gametes and zygotes caused by viability loci in the segregating progeny. However, the maternal cytoplasm may also be involved in the viability selection of gametes and zygotes. The objectives of this study were to map the segregation distortion loci (SDL) in maize and to test the hypothesis that the viability of gametes and zygotes may also be associated with the maternal cytoplasmic environment. In the present study, a reciprocal mating design was conducted to generate an F2-segregating population. A linkage map was constructed with 126 microsatellite markers. A whole-genome scan was performed to detect the SDL in segregating populations with different maternal cytoplasm environments. Altogether, 14 SDL with strong LOD (logarithm (base 10) of odds) supports were identified in the specifically designed F2 populations. Interestingly, we found dramatic changes in the genotypic frequencies of the SDL in the two maternal cytoplasmic backgrounds, which indicated a change in the viability of gametes and zygotes in different cytoplasmic environments. Furthermore, in the JB cytoplasmic background, most of the detected SDL and complete distortion markers exhibited similar bias patterns favouring the Y53 alleles. These results suggested that selfish cytoplasmic elements may have an important role in shaping the patterns of segregation distortion in F2 populations through selective viability of gametes and zygotes.

Increasing Discussions of Intimate Partner Violence in Prenatal Care Using Video Doctor Plus Provider Cueing: A Randomized Controlled Trial  

PubMed Central

Purpose To report the effectiveness of a prenatal intervention and to provide evidence that prenatal visits provide an opportune time for health assessment and counseling with abused women. Methods Fifty ethnically diverse pregnant women who presented for routine prenatal care and who also reported being at risk for intimate partner violence (IPV) were recruited to the study. Participants were assigned to either usual care or the Video Doctor plus Provider Cueing intervention. At baseline and 1-month later at another routine prenatal visit, intervention group participants received a 15-minute Video Doctor assessment and interactive tailored counseling. Their providers received a printed Cue Sheet alert and suggested counseling statements. Main findings Participants in the intervention group were significantly more likely to report provider-patient discussions of IPV compared to participants receiving usual care at baseline (81.8% vs. 16.7%, p < 0.001) and at the 1-month follow-up (70.0% vs. 23.5%, p = 0.005). Summing the number of patient-provider discussions across the two visits at baseline and one month later, intervention participants were significantly more likely to have IPV risk discussion with their providers at one or both visits (90.0% vs. 23.6%, p< 0.001) compared to the participants who received usual care. When specifically asked about the helpfulness of these IPV-related discussions, 20 out of 22 (90.9%) participants rated the discussion as helpful or very helpful at baseline and all 18 (100%) participants rated the discussion as helpful or very helpful at the 1-month follow-up. Conclusions Video Doctor plus Provider Cueing intervention significantly increases the likelihood of provider-patient IPV discussion with pregnant women with a history of abuse. PMID:21185737

Study protocol of a randomized controlled trial comparing Mindfulness-Based Stress Reduction with treatment as usual in reducing psychological distress in patients with lung cancer and their partners: the MILON study  

PubMed Central

Background Lung cancer is the leading cause of cancer death worldwide and characterized by a poor prognosis. It has a major impact on the psychological wellbeing of patients and their partners. Recently, it has been shown that Mindfulness-Based Stress Reduction (MBSR) is effective in reducing anxiety and depressive symptoms in cancer patients. The generalization of these results is limited since most participants were female patients with breast cancer. Moreover, only one study examined the effectiveness of MBSR in partners of cancer patients. Therefore, in the present trial we study the effectiveness of MBSR versus treatment as usual (TAU) in patients with lung cancer and their partners. Methods/Design A parallel group, randomized controlled trial is conducted to compare MBSR with TAU. Lung cancer patients who have received or are still under treatment, and their partners are recruited. Assessments will take place at baseline, post intervention and at three-month follow-up. The primary outcome is psychological distress (i.e. anxiety and depressive symptoms). Secondary outcomes are quality of life (only for patients), caregiver appraisal (only for partners), relationship quality and spirituality. In addition, cost-effectiveness ratio (only in patients) and several process variables are assessed. Discussion This trial will provide information about the clinical and cost-effectiveness of MBSR compared to TAU in patients with lung cancer and their partners.

Romantic partner selection and socialization during early adolescence.  

PubMed

This prospective study examined romantic partner selection and socialization among a sample of 78 young adolescents (6th-8th graders). Independent assessments of adolescent and romantic partner adjustment were collected before and after relationships initiated via peer nomination and self-report. Prior to their relationship, adolescents and partners were significantly alike on popularity, physical attraction, and depressive symptoms. Controlling for initial similarity, partners' popularity, depressive symptoms, relational aggression, and relational victimization significantly predicted changes in adolescents' functioning in these areas over time. However, the magnitude and direction of change varied according to adolescents' and partners' prerelationship functioning. In general, adolescents who dated high-functioning partners changed more than those who dated low-functioning partners, and partner characteristics predicted greater change among low- versus high-functioning adolescents. Results were consistent even when controlling for best friend characteristics. The current findings are among the first to demonstrate unique contributions of romantic partner characteristics to adolescents' psychosocial functioning. PMID:19037942

Male partner selectivity, romantic confidence, and media depictions of partner scarcity.  

PubMed

An experiment was conducted to explore the effects of exposure to partner scarcity or abundance messages on men's partner selectivity, romantic confidence, and self-assessed attractiveness. Undergraduate male participants watched a soap opera narrative featuring either two men competing over one potential female partner (partner scarcity) or two women competing over one potential male partner (partner abundance). Relative to control subjects, watching either narrative reduced romantic confidence. Experimental condition also affected partner selectivity and self-assessed attractiveness, though both effects were moderated by endorsement of traditional masculine ideology. Viewing the abundance narrative resulted in greater selectivity and self-assessed attractiveness for men high in endorsement of traditional masculinity but diminished selectivity and self-assessed attractiveness for men low in endorsement of traditional masculine identity.

Two-generation analysis of pollen flow across a landscape. I. Male gamete heterogeneity among females.  

PubMed

Gene flow is a key factor in the spatial genetic structure in spatially distributed species. Evolutionary biologists interested in microevolutionary processess and conservation biologists interested in the impact of landscape change require a method that measures the real time process of gene movement. We present a novel two-generation (parent-offspring) approach to the study of genetic structure (TwoGener) that allows us to quantify heterogeneity among the male gamete pools sampled by maternal trees scattered across the landscape and to estimate mean pollination distance and effective neighborhood size. First, we describe the model's elements: genetic distance matrices to estimate intergametic distances, molecular analysis of variance to determine whether pollen profiles differ among mothers, and optimal sampling considerations. Second, we evaluate the model's effectiveness by simulating spatially distributed populations. Spatial heterogeneity in male gametes can be estimated by phiFT, a male gametic analogue of Wright's F(ST) and an inverse function of mean pollination distance. We illustrate TwoGener in cases where the male gamete can be categorically or ambiguously determined. This approach does not require the high level of genetic resolution needed by parentage analysis, but the ambiguous case is vulnerable to bias in the absence of adequate genetic resolution. Finally, we apply TwoGener to an empirical study of Quercus alba in Missouri Ozark forests. We find that phiFT = 0.06, translating into about eight effective pollen donors per female and an effective pollination neighborhood as a circle of radius about 17 m. Effective pollen movement in Q. alba is more restricted than previously realized, even though pollen is capable of moving large distances. This case study illustrates that, with a modest investment in field survey and laboratory analysis, the TwoGener approach permits inferences about landscape-level gene movements. PMID:11308084

Making Muslim babies: IVF and gamete donation in Sunni versus Shi'a Islam.  

PubMed

Medical anthropological research on science, biotechnology, and religion has focused on the "local moral worlds" of men and women as they make difficult decisions regarding their health and the beginnings and endings of human life. This paper focuses on the local moral worlds of infertile Muslims as they attempt to make, in the religiously correct fashion, Muslim babies at in vitro fertilization (IVF) clinics in Egypt and Lebanon. As early as 1980, authoritative fatwas issued from Egypt's famed Al-Azhar University suggested that IVF and similar technologies are permissible as long as they do not involve any form of third-party donation (of sperm, eggs, embryos, or uteruses). Since the late 1990s, however, divergences in opinion over third-party gamete donation have occurred between Sunni and Shi'ite Muslims, with Iran's leading ayatollah permitting gamete donation under certain conditions. This Iranian fatwa has had profound implications for the country of Lebanon, where a Shi'ite majority also seeks IVF services. Based on three periods of ethnographic research in Egyptian and Lebanese IVF clinics, this paper explores official and unofficial religious discourses surrounding the practice of IVF and third-party donation in the Muslim world, as well as the gender implications of gamete donation for Muslim marriages.

Globalization and gametes: reproductive 'tourism,' Islamic bioethics, and Middle Eastern modernity.  

PubMed

'Reproductive tourism' has been defined as the search for assisted reproductive technologies (ARTs) and human gametes (eggs, sperm, embryos) across national and international borders. This article conceptualizes reproductive tourism within 'global reproscapes,' which involve the circulation of actors, technologies, money, media, ideas, and human gametes, all moving in complicated manners across geographical landscapes. Focusing on the Muslim countries of the Middle East, the article explores the Islamic 'local moral worlds' informing the movements of Middle Eastern infertile couples. The ban on third-party gamete donation in Sunni Muslim-majority countries and the recent allowance of donor technologies in the Shia Muslim-majority countries of Iran and Lebanon have led to significant movements of infertile couples across Middle Eastern national borders. In the new millennium, Iran is leading the way into this 'brave new world' of high-tech, third-party assisted conception, with Islamic bioethical discourses being used to justify various forms of technological assistance. Although the Middle East is rarely regarded in this way, it is a key site for understanding the intersection of technoscience, religious morality, and modernity, all of which are deeply implicated in the new world of reproductive tourism.

Female and male gamete mitochondria are distinct and complementary in transcription, structure, and genome function.  

PubMed

Respiratory electron transport in mitochondria is coupled to ATP synthesis while generating mutagenic oxygen free radicals. Mitochondrial DNA mutation then accumulates with age, and may set a limit to the lifespan of individual, multicellular organisms. Why is this mutation not inherited? Here we demonstrate that female gametes-oocytes-have unusually small and simple mitochondria that are suppressed for DNA transcription, electron transport, and free radical production. By contrast, male gametes-sperm-and somatic cells of both sexes transcribe mitochondrial genes for respiratory electron carriers and produce oxygen free radicals. This germ-line division between mitochondria of sperm and egg is observed in both the vinegar fruitfly and the zebrafish-species spanning a major evolutionary divide within the animal kingdom. We interpret these findings as an evidence that oocyte mitochondria serve primarily as genetic templates, giving rise, irreversibly and in each new generation, to the familiar energy-transducing mitochondria of somatic cells and male gametes. Suppressed mitochondrial metabolism in the female germ line may therefore constitute a mechanism for increasing the fidelity of mitochondrial DNA inheritance. PMID:24068653

Ploidy frequencies in plants with ploidy heterogeneity: fitting a general gametic model to empirical population data  

PubMed Central

Genome duplication (polyploidy) is a recurrent evolutionary process in plants, often conferring instant reproductive isolation and thus potentially leading to speciation. Outcome of the process is often seen in the field as different cytotypes co-occur in many plant populations. Failure of meiotic reduction during gametogenesis is widely acknowledged to be the main mode of polyploid formation. To get insight into its role in the dynamics of polyploidy generation under natural conditions, and coexistence of several ploidy levels, we developed a general gametic model for diploid–polyploid systems. This model predicts equilibrium ploidy frequencies as functions of several parameters, namely the unreduced gamete proportions and fertilities of higher ploidy plants. We used data on field ploidy frequencies for 39 presumably autopolyploid plant species/populations to infer numerical values of the model parameters (either analytically or using an optimization procedure). With the exception of a few species, the model fit was very high. The estimated proportions of unreduced gametes (median of 0.0089) matched published estimates well. Our results imply that conditions for cytotype coexistence in natural populations are likely to be less restrictive than previously assumed. In addition, rather simple models show sufficiently rich behaviour to explain the prevalence of polyploids among flowering plants. PMID:23193129

Peering beneath the surface: novel imaging techniques to noninvasively select gametes and embryos for ART.  

PubMed

Embryo imaging has long been a critical tool for in vitro fertilization laboratories, aiding in morphological assessment of embryos, which remains the primary tool for embryo selection. With the recent emergence of clinically applicable real-time imaging systems to assess embryo morphokinetics, a renewed interest has emerged regarding noninvasive methods to assess gamete and embryo development as a means of inferring quality. Several studies exist that utilize novel imaging techniques to visualize or quantify intracellular components of gametes and embryos with the intent of correlating localization of organelles or molecular constitution with quality or outcome. However, the safety of these approaches varies due to the potential detrimental impact of light exposure or other variables. Along with complexity of equipment and cost, these drawbacks currently limit clinical application of these novel microscopes and imaging techniques. However, as evidenced by clinical incorporation of some real-time imaging devices as well as use of polarized microscopy, some of these imaging approaches may prove to be useful. This review summarizes the existing literature on novel imaging approaches utilized to examine gametes and embryos. Refinement of some of these imaging systems may permit clinical application and serve as a means to offer new, noninvasive selection tools to improve outcomes for various assisted reproductive technology procedures.

The family partners for health study: a cluster randomized controlled trial for child and parent weight management  

PubMed Central

Objective: The purpose of this study was to test a two-phased nutrition and exercise education, coping skills training, and exercise intervention program for overweight or obese low-income ethnic minority 2nd to 4th grade children and their parents in rural North Carolina, USA. Methods: A cluster randomized controlled trial was carried out with 358 children (7–10 years) and a parent for each child (n=358). General linear mixed models were used to determine the effects of the intervention on weight, adiposity, health behaviors, and eating and exercise self-efficacy by examining changes in children and parents from baseline to completion of the study (18 months). Results: At 18 months, children in the experimental group did not have a significantly decreased body mass index (BMI) percentile (P=0.470); however, they showed a reduction in the growth rate of their triceps (P=0.001) and subscapular skinfolds (P<0.001) and an improvement in dietary knowledge (P=0.018) and drank less than one glass of soda per day (P=0.052) compared with the control group. Parents in the experimental group had decreased BMI (P=0.001), triceps (P<0.001) and subscapular skinfolds (P<0.001) and increased nutrition (P=0.003) and exercise (P<0.001) knowledge and more often drank water or unsweetened drinks (P=0.029). At 18 months, children in the experimental group did not show significant improvement in eating (P=0.956) or exercise self-efficacy (P=0.976). Experimental parents demonstrated improved socially acceptable eating self-efficacy (P=0.013); however, they did not show significant improvement in self-efficacy pertaining to emotional eating (P=0.155) and exercise (P=0.680). Conclusion: The results suggest that inclusion of children and parents in the same intervention program is an effective way to decrease adiposity and improve nutrition behaviors in both children and parents and improve weight and eating self-efficacy in parents.

Rationale, design, methodology and sample characteristics for the family partners for health study: a cluster randomized controlled study  

PubMed Central

Background Young children who are overweight are at increased risk of becoming obese and developing type 2 diabetes and cardiovascular disease later in life. Therefore, early intervention is critical. This paper describes the rationale, design, methodology, and sample characteristics of a 5-year cluster randomized controlled trial being conducted in eight elementary schools in rural North Carolina, United States. Methods/Design The first aim of the trial is to examine the effects of a two-phased intervention on weight status, adiposity, nutrition and exercise health behaviors, and self-efficacy in overweight or obese 2nd, 3 rd, and 4th grade children and their overweight or obese parents. The primary outcome in children is stabilization of BMI percentile trajectory from baseline to 18 months. The primary outcome in parents is a decrease in BMI from baseline to 18 months. Secondary outcomes for both children and parents include adiposity, nutrition and exercise health behaviors, and self-efficacy from baseline to 18 months. A secondary aim of the trial is to examine in the experimental group, the relationships between parents and children's changes in weight status, adiposity, nutrition and exercise health behaviors, and self-efficacy. An exploratory aim is to determine whether African American, Hispanic, and non-Hispanic white children and parents in the experimental group benefit differently from the intervention in weight status, adiposity, health behaviors, and self-efficacy. A total of 358 African American, non-Hispanic white, and bilingual Hispanic children with a BMI ? 85th percentile and 358 parents with a BMI ? 25 kg/m2 have been inducted over 3 1/2 years and randomized by cohort to either an experimental or a wait-listed control group. The experimental group receives a 12-week intensive intervention of nutrition and exercise education, coping skills training and exercise (Phase I), 9 months of continued monthly contact (Phase II) and then 6 months (follow-up) on their own. Safety endpoints include adverse event reporting. Intention-to-treat analysis will be applied to all data. Discussion Findings from this trial may lead to an effective intervention to assist children and parents to work together to improve nutrition and exercise patterns by making small lifestyle pattern changes.

Sweet Sensor, Surprising Partners  

NSDL National Science Digital Library

Hexokinase1 (HXK1) is an evolutionarily conserved glucose sensor in plants. However, the molecular mechanism through which HXK1 controls the expression of genes encoding proteins involved in photosynthesis is a mystery. Recent research demonstrates that a previously unknown HXK1 nuclear complex controls the expression of specific photosynthetic genes, a process that is independent of glucose metabolism but requires two unexpected partners, VHA-B1 and RPT5B. Both VHA-B1 and RPT5B have well-established and conserved functions in processes that are seemingly unrelated to glucose-dependent regulation of gene expression, and neither of them is a predominantly nuclear protein. Biochemical, genetic, and molecular evidence demonstrates that VHA-B1 and RPT5B directly interact with HXK1 in the nucleus and that the HXK1 complex binds to the cis-acting elements of chlorophyll a/b binding protein 2, a photosynthetic gene that is transcriptionally suppressed by glucose. The identification of the HXK1 nuclear complex reveals an unexpected glucose-signaling mechanism and reinforces the notion that metabolic enzymes can play unique roles in signal transduction by directly controlling gene expression in the nucleus.

Actin-based spindle positioning: new insights from female gametes.  

PubMed

Asymmetric divisions are essential in metazoan development, where they promote the emergence of cell lineages. The mitotic spindle has astral microtubules that contact the cortex, which act as a sensor of cell geometry and as an integrator to orient cell division. Recent advances in live imaging revealed novel pools and roles of F-actin in somatic cells and in oocytes. In somatic cells, cytoplasmic F-actin is involved in spindle architecture and positioning. In starfish and mouse oocytes, newly discovered meshes of F-actin control chromosome gathering and spindle positioning. Because oocytes lack centrosomes and astral microtubules, F-actin networks are key players in the positioning of spindles by transmitting forces over long distances. Oocytes also achieve highly asymmetric divisions, and thus are excellent models to study the roles of these newly discovered F-actin networks in spindle positioning. Moreover, recent studies in mammalian oocytes provide a further understanding of the organisation of F-actin networks and their biophysical properties. In this Commentary, we present examples of the role of F-actin in spindle positioning and asymmetric divisions, with an emphasis on the most up-to-date studies from mammalian oocytes. We also address specific technical issues in the field, namely live imaging of F-actin networks and stress the need for interdisciplinary approaches. PMID:24413163

Cytoskeletal organisation and modification during pollen tube arrival, gamete delivery and fertilisation in Plumbago zeylanica.  

PubMed

The cytoskeletal organisation of the isolated embryo sac and egg cells of Plumbago zeylanica was examined before, during and after pollen tube penetration into the embryo sac to determine the potential involvement of microtubules and actin filaments in fertilisation. Material was singly and triply stained using Hoechst 33258 to localise DNA, fluorescein isothiocyanate (FITC)-labelled anti-alpha-tubulin to detect microtubules and rhodamine-phalloidin to visualise F-actin. Microtubules in the unfertilised egg cell are longitudinally aligned in the micropylar and mid-lateral areas, aggregating into bundles near the filiform apparatus. In the perinuclear cytoplasm of the egg cell, microtubules become more or less randomly aligned. F-actin bundles form a longitudinally aligned mesh in the chalazal cytoplasm of the egg cell. In the central cell, microtubules and F-actin are distributed along transvacuolar strands and are also evident in the perinuclear region and at the periphery of the cell. During pollen tube penetration, sparse microtubule bundles near the pathway of the pollen tube may form an apparent microtubular 'conduit' surrounding the male gametes at the delivery site. Actin aggregates become organised near the pathway of the pollen tube and at the delivery site of the sperm cells. Subsequently, actin aggregates form a 'corona' structure in the intercellular region between the egg and central cell where gametic fusion occurs. The corona may have a role in maintaining the close proximity of the egg and central cell and helping the two sperm cells move and bind to their target cells. The cytoskeleton may also be involved in causing the two nuclei of the egg and central cell to approach one another at the site of gametic fusion and transporting the two sperm nuclei into alignment with their respective female nucleus. The cytoskeleton is reorganised during early embryogenesis. PMID:8081810

Characterization of gametes in two phyllostomid bat species: Artibeus jamaicensis and Sturnira lilium.  

PubMed

Morphology of gametes is used to understand the physiological processes in reproduction among domestic and wild animals. These gametes are used in assisted reproductive technology (ART) and conservation programs. In the case of Artibeus jamaicensis and Sturnira lilium, few studies have been conducted related to these issues. The aim of this study was to describe the structure of spermatozoa, semen characteristics and also the morphology and quality of cumulus oocyte complexes (COC) of A. jamaicensis and S. lilium. Semen characteristics were: A. jamaicensis had a sperm concentration of 4.26×10(6)sperm/ml, progressive motility of 34.55%; viability of 73.23%; head, tail and mid-piece abnormalities of 12.50%. Head length was 6.26?m, mid-piece 18.61?m and tail 70.92?m. S. lilium, had a sperm concentration of 5.15×10(6)sperm/ml, progressive motility of 60.00%, viability of 83.82%; abnormalities in head, tail and mid-piece of 13.77%. Head length was 7.01?m, mid-piece 20.33?m and tail 70.50?m. On average 12.8 of right ovarian oocytes and 9.9 of left ovarian oocytes of A. jamaicensis were recovered. For S. lilium on average 10.7 oocytes from the right ovary and 10.9 oocytes from the left ovary were recovered, ranging in quality from excellent to poor. Sperm morphology and quality of COC were similar to those for other domestic and wild animals. Bat gametes can be used for the study of reproductive biology, in conservation programs and assisted reproductive technology (ART) among domestic and wild animals. PMID:24576400

Diploid clone produces unreduced diploid gametes but tetraploid clone generates reduced diploid gametes in the Misgurnus loach.  

PubMed

Most individuals of the loach Misgurnus anguillicaudatus reproduce bisexually, but cryptic clonal lineages reproduce by natural gynogenesis of unreduced diploid eggs that are genetically identical to maternal somatic cells. Triploid progeny often occur by the accidental incorporation of a sperm nucleus into diploid eggs. Sex reversal from a genetic female to a physiological male is easily induced in this species by androgen treatment and through environmental influences. Here, we produced clonal tetraploid individuals by two methods: 1) fertilization of diploid eggs from a clonal diploid female with diploid sperm of a hormonally sex-reversed clonal diploid male and 2) artificial inhibition of the release of the second polar body in eggs of clonal diploid females just after initiation of gynogenetic development. There is no genetic difference between the clonal diploid and tetraploid individuals except for the number of chromosome sets or genomes. Clonal tetraploid males never produced unreduced tetraploid sperm, only diploid sperm that were genetically identical to those of a clonal diploid. Likewise, clonal tetraploid females did not form unreduced tetraploid eggs, just diploid eggs. However, the eggs' genotypes were identical to those of the original clone, and almost all the eggs initiated natural gynogenesis. Thus, gametogenesis of the clonal tetraploid loach is controlled by the presence of two chromosome sets to pair, thereby preserving the normal meiotic process, i.e., the formation of bivalents and subsequently two successive divisions.

The Social Health Intervention Project (SHIP): Protocol for a randomized controlled clinical trial assessing the effectiveness of a brief motivational intervention for problem drinking and intimate partner violence in an urban emergency department  

PubMed Central

Background There is a strong reciprocal association between two highly prevalent public health problems: intimate partner violence and heavy drinking, both of which remain major sources of morbidity and mortality. Brief interventions in the Emergency Department setting have been found to be effective in reducing alcohol-related injury but neither classic intimate partner violence nor substance abuse interventions have adequately integrated assessment and treatment for these co-occurring conditions. The overall goal of this study is to determine whether a motivational intervention delivered at the time of an Emergency Department visit will reduce heavy drinking and improve the safety of women experiencing intimate partner violence. Methods and design We are completing data collection for a randomized controlled trial enrolling 600 female patients, age 18–64, presenting to one of two urban Emergency Departments, who self-disclose both problem drinking and intimate partner violence. Eligible patients are randomized to a brief manual-guided motivational intervention, and a phone booster at 10 days. The intervention, which is delivered by masters-level therapists during the Emergency Department visit, is recorded and monitored for fidelity. Primary outcomes are episodes of heavy drinking and incidents of intimate partner violence, assessed weekly by Interactive Voice Response System for 12 weeks and at 3, 6 and 12 months by interviewers blinded to group assignment. To identify the impact of assessment alone, we included a no-contact control group assessed only once at 3 months. Secondary outcomes include violence severity, changes in the Composite Abuse Scale and alcohol quantity/frequency, along with other health-related behaviors. The analysis will also explore the impact of likely mediators and moderators of the intervention. Discussion While screening and intervention for intimate partner violence is now recommended for women of child bearing age in health care settings, there is a need for rigorous evaluations of what works for whom. Upon completion, we will have high-quality evidence regarding the effectiveness of a low-intensity, brief motivational intervention, delivered by social workers in the Emergency Department setting, for decreasing episodes of heavy drinking and intimate partner violence. Ultimately, this is a model could be generalizable to other acute health care settings. Trial Registration ClinicalTrials.gov Registration Number: NCT01207258 PMID:24742322

The Chlamydomonas mating type plus fertilization tubule, a prototypic cell fusion organelle: isolation, characterization, and in vitro adhesion to mating type minus gametes.  

PubMed

In the biflagellated alga Chlamydomonas, adhesion and fusion of the plasma membranes of gametes during fertilization occurs via an actin-filled, microvillus-like cell protrusion. Formation of this approximately 3-microm-long fusion organelle, the Chlamydomonas fertilization tubule, is induced in mating type plus (mt+) gametes during flagellar adhesion with mating type minus (mt-) gametes. Subsequent adhesion between the tip of the mt+ fertilization tubule and the apex of a mating structure on mt- gametes is followed rapidly by fusion of the plasma membranes and zygote formation. In this report, we describe the isolation and characterization of fertilization tubules from mt+ gametes activated for cell fusion. Fertilization tubules were detached by homogenization of activated mt+ gametes in an EGTA-containing buffer and purified by differential centrifugation followed by fractionation on sucrose and Percoll gradients. As determined by fluorescence microscopy of samples stained with a fluorescent probe for filamentous actin, the method yielded 2-3 x 10(6) fertilization tubules/microg protein, representing up to a 360-fold enrichment of these organelles. Examination by negative stain electron microscopy demonstrated that the purified fertilization tubules were morphologically indistinguishable from fertilization tubules on intact, activated mt+ gametes, retaining both the extracellular fringe and the internal array of actin filaments. Several proteins, including actin as well as two surface proteins identified by biotinylation studies, copurified with the fertilization tubules. Most importantly, the isolated mt+ fertilization tubules bound to the apical ends of activated mt- gametes between the two flagella, the site of the mt- mating structure; a single fertilization tubule bound per cell, binding was specific for gametes, and fertilization tubules isolated from trypsin-treated, activated mt+ gametes did not bind to activated mt- gametes.

Gamete derivation from stem cells: revisiting the concept of genetic parenthood.  

PubMed

Genetic parenthood is usually portrayed as a value-neutral concept that can be confirmed or rejected based on objective, scientific tests. However, on inspection, it is exposed as a very complex idea that we might need to consider as something that comes in different shapes and forms and that is open to interpretation rather than being clearly defined and fixed. Different people may therefore also desire different aspects of the general concept of genetic parenthood, which implies that some may not even be satisfied with gametes that have all the properties that their own natural gametes would have, whereas others may be satisfied with a much simpler solution. Encouraging infertility patients to gain insight into what it is exactly that they hope to gain by pursuing genetic parenthood (rather than choosing for donor conception or adoption) may lead them to recognise that the added advantage may be limited and may be acquired in other ways as well. Nevertheless, many people will find it difficult to let go of the desire for genetic parenthood as it is deeply rooted in our genes. Infertility is experienced as a grave medical condition and entails an intense grieving process for many. For that reason alone it is important that the medical and research community develop and apply methods to help people in their quest for genetic parenthood. On the other hand, it is important not to reinforce the dogma that genetic parenthood is 'the best kind of parenthood'. PMID:24951670

Postcopulatory selection for dissimilar gametes maintains heterozygosity in the endangered North Atlantic right whale  

PubMed Central

Although small populations are expected to lose genetic diversity through genetic drift and inbreeding, a number of mechanisms exist that could minimize this genetic decline. Examples include mate choice for unrelated mates and fertilization patterns biased toward genetically dissimilar gametes. Both processes have been widely documented, but the long-term implications have received little attention. Here, we combined over 25 years of field data with high-resolution genetic data to assess the long-term impacts of biased fertilization patterns in the endangered North Atlantic right whale. Offspring have higher levels of microsatellite heterozygosity than expected from this gene pool (effect size = 0.326, P < 0.011). This pattern is not due to precopulatory mate choice for genetically dissimilar mates (P < 0.600), but instead results from postcopulatory selection for gametes that are genetically dissimilar (effect size = 0.37, P < 0.003). The long-term implication is that heterozygosity has slowly increased in calves born throughout the study period, as opposed to the slight decline that was expected. Therefore, this mechanism represents a natural means through which small populations can mitigate the loss of genetic diversity over time. PMID:24223284

Triploid planarian reproduces truly bisexually with euploid gametes produced through a different meiotic system between sex.  

PubMed

Although polyploids are common among plants and some animals, polyploidization often causes reproductive failure. Triploids, in particular, are characterized by the problems of chromosomal pairing and segregation during meiosis, which may cause aneuploid gametes and results in sterility. Thus, they are generally considered to reproduce only asexually. In the case of the Platyhelminthes Dugesia ryukyuensis, populations with triploid karyotypes are normally found in nature as both fissiparous and oviparous triploids. Fissiparous triploids can also be experimentally sexualized if they are fed sexual planarians, developing both gonads and other reproductive organs. Fully sexualized worms begin reproducing by copulation rather than fission. In this study, we examined the genotypes of the offspring obtained by breeding sexualized triploids and found that the offspring inherited genes from both parents, i.e., they reproduced truly bisexually. Furthermore, meiotic chromosome behavior in triploid sexualized planarians differed significantly between male and female germ lines, in that female germ line cells remained triploid until prophase I, whereas male germ line cells appeared to become diploid before entry into meiosis. Oocytes at the late diplotene stage contained not only paired bivalents but also unpaired univalents that were suggested to produce diploid eggs if they remained in subsequent processes. Triploid planarians may therefore form euploid gametes by different meiotic systems in female and male germ lines and thus are be able to reproduce sexually in contrast to many other triploid organisms.

Intraspecific genetic analysis, gamete release performance, and growth of Sargassum muticum (Fucales, Phaeophyta) from China  

NASA Astrophysics Data System (ADS)

Sargassum muticum is one of the most abundant and conspicuous native macroalgae species on the northern coasts of China. It often forms large-scale seaweed beds in subtidal zones. This investigation was designed to understand the intraspecific genetic relationships of this alga based on samples collected from four northern coastal sites of China, and to evaluate gamete release and growth capacity in laboratory conditions. The nuclear internal transcribed spacer 2 (ITS2) sequences of 16 samples from four locations were identical. Based on cox3 gene and partial rbcLS operon sequences, intraspecific genetic variability was detected with three and two ribotypes, respectively. Temperature, not irradiance, was shown to significantly affect gamete release and fertilization. Elevated temperature and irradiance enhanced the growth of germlings and vegetative branchlets. Maximum growth rate of germlings was detected at 18-24°C and an irradiance of 60-100 ?mol photons/(m2·s). Under ambient conditions (12-25°C and 60-125 ?mol photons/(m2·s)), relative growth rate of young branchlets could reach 7.5%/d.

The use of Pacific herring gametes and embryos for assessing natural and anthropogenic stressors  

SciTech Connect

For marine and estuarine waters in Northern California through the Pacific Northwest, an ecologically important endemic teleost system has been lacking for use in toxicological studies of embryo development. Since Pacific herring (Clupea pallasi) spawn in estuaries during periods of freshwater input in shallow protected waters, their gametes/embryos are potentially impacted by altered salinities and pollutants. Their results demonstrate that advantages of the Pacific herring system include: (1) gametes are easily collected from mature adults, and are viable when stored up to 1 week; (2) embryos and larvae can be cultured through hatching ({approximately}10 days) in the laboratory (static or flow-through), and when outplanted in the field; and (3), distinct endpoints can be assessed, including initiation of sperm motility, fertilization, development, hatching success, and larval morphology. The authors have investigated 3 stressors which can impact early life stages of herring: salinity, creosote, and bleached kraft mill effluent (BKME). Results demonstrate that sperm motility initiation, fertilization, and development are perturbed by altered salinities, and that effects are dose-dependent with respect to both salinity and sodium. Monitoring of natural spawns on creosote pilings indicated perturbation of development; this is similar to what was observed in laboratory exposures. Finally, a major toxic constituent of BKME specifically impacts sperm and inhibits fertilization.

Effect of Nurse Home Visits vs. Usual Care on Reducing Intimate Partner Violence in Young High-Risk Pregnant Women: A Randomized Controlled Trial  

PubMed Central

Background Expectant mothers and mothers of young children are especially vulnerable to intimate partner violence (IPV). The nurse-family partnership (NFP) is a home visitation program in the United States effective for the prevention of adverse child health outcomes. Evidence regarding the effect of nurse home visiting on IPV is inconsistent. This study aims to study the effect of VoorZorg, the Dutch NFP, on IPV. Methods A random sample of 460 eligible disadvantaged women <26 years, with no previous live births, was randomized. Women in the control group (C; n=223) received usual care; women in the intervention group (I; n=237) received usual care plus nurse home visits periodically during pregnancy and until the child’s second birthday. Results At 32 weeks of pregnancy, women in the intervention group self-reported significantly less IPV victimization than women in the control group in: level 2 psychological aggression (C: 56% vs. I: 39%), physical assault level 1 (C: 58% vs. I: 40%) and level 2 (C: 31% vs. I: 20%), and level 1 sexual coercion (C: 16% vs. I: 8%). Furthermore, women in the intervention group reported significantly less IPV perpetration in: level 2 psychological aggression (C: 60% vs. I: 46%), level 1 physical assault (C: 65% vs. I: 52%), and level 1 injury (C: 27% vs. I: 17%). At 24 months after birth, IPV victimization was significantly lower in the intervention group for level 1 physical assault (C: 44% vs. I: 26%), and IPV perpetration was significantly lower for level 1 sexual assault (C: 18% vs. I: 3%). Multilevel analyses showed a significant improvement in IPV victimization and perpetration among women in the intervention group at 24 months after birth. Conclusion VoorZorg, compared with the usual care, is effective in reducing IPV during pregnancy and in the two years after birth among young high-risk women.

Gamete donors' expectations and experiences of contact with their donor offspring  

PubMed Central

STUDY QUESTION What are the expectations and experiences of anonymous gamete donors about contact with their donor offspring? SUMMARY ANSWER Rather than consistently wanting to remain distant from their donor offspring, donors' expectations and experiences of contact with donor offspring ranged from none to a close personal relationship. WHAT IS KNOWN ALREADY Donor conception is part of assisted reproduction in many countries, but little is known about its continuing influence on gamete donors' lives. STUDY DESIGN, SIZE, DURATION A qualitative research model appropriate for understanding participants' views was employed; semi-structured interviews were conducted during January–March 2013. PARTICIPANTS/MATERIALS, SETTING, METHODS Before 1998, gamete donors in Victoria, Australia, were subject to evolving legislation that allowed them to remain anonymous or (from 1988) to consent to the release of identifying information. An opportunity to increase knowledge of donors' expectations and experiences of contact with their donor offspring recently arose in Victoria when a recommendation was made to introduce mandatory identification of donors on request from their donor offspring, with retrospective effect. Pre-1998 donors were invited through an advertising campaign to be interviewed about their views, experiences and expectations; 36 sperm donors and 6 egg donors participated. MAIN RESULTS AND THE ROLE OF CHANCE This research is unusual in achieving participation by donors who would not normally identify themselves to researchers or government inquiries. Qualitative thematic analysis revealed that most donors did not characterize themselves as parents of their donor offspring. Donors' expectations and experiences of contact with donor offspring ranged from none to a close personal relationship. LIMITATIONS, REASONS FOR CAUTION It is not possible to establish whether participants were representative of all pre-1998 donors. WIDER IMPLICATIONS OF THE FINDINGS Anonymous donors' needs and desires are not homogeneous; policy and practice should be sensitive and responsive to a wide range of circumstances and preferences. Decisions made to restrict or facilitate contact or the exchange of information have ramifications for donors as well as for donor-conceived people. STUDY FUNDING/COMPETING INTEREST(S) The study was funded by the Victorian Department of Health. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER Not applicable.

Function of the male-gamete-specific fusion protein HAP2 in a seven-sexed ciliate.  

PubMed

HAP2, a male-gamete-specific protein conserved across vast evolutionary distances, has garnered considerable attention as a potential membrane fusogen required for fertilization in taxa ranging from protozoa and green algae to flowering plants and invertebrate animals [1-6]. However, its presence in Tetrahymena thermophila, a ciliated protozoan with seven sexes or mating types that bypasses the production of male gametes, raises interesting questions regarding the evolutionary origins of gamete-specific functions in sexually dimorphic species. Here we show that HAP2 is expressed in all seven mating types of T. thermophila and that fertility is only blocked when the gene is deleted from both cells of a mating pair. HAP2 deletion strains of complementary mating types can recognize one another and form pairs; however, pair stability is compromised and membrane pore formation at the nuclear exchange junction is blocked. The absence of pore formation is consistent with previous studies suggesting a role for HAP2 in gamete fusion in other systems. We propose a model in which each of the several hundred membrane pores established at the conjugation junction of mating Tetrahymena represents the equivalent of a male/female interface, and that pore formation is driven on both sides of the junction by the presence of HAP2. Such a model supports the idea that many of the disparate functions of sperm and egg were shared by the "isogametes" of early eukaryotes and became partitioned to either male or female sex cells later in evolution.

Sex-Specific Posttranslational Regulation of the Gamete Fusogen GCS1 in the Isogamous Volvocine Alga Gonium pectorale  

PubMed Central

Male and female, generally defined based on differences in gamete size and motility, likely have multiple independent origins, appearing to have evolved from isogamous organisms in various eukaryotic lineages. Recent studies of the gamete fusogen GCS1/HAP2 indicate that this protein is deeply conserved across eukaryotes, and its exclusive and/or functional expression generally resides in males or in male homologues. However, little is known regarding the conserved or primitive molecular traits of males and females within eukaryotes. Here, using morphologically indistinguishable isogametes of the colonial volvocine Gonium pectorale, we demonstrated that GCS1 is differently regulated between the sexes. G. pectorale GCS1 molecules in one sex (homologous to male) are transported from the gamete cytoplasm to the protruded fusion site, whereas those of the other sex (females) are quickly degraded within the cytoplasm upon gamete activation. This molecular trait difference might be conserved across various eukaryotic lineages and may represent male and female prototypes originating from a common eukaryotic ancestor. PMID:24632243

The Levels of Male Gametic Mitochondrial DNA Are Highly Regulated in Angiosperms with Regard to Mitochondrial Inheritance[W  

PubMed Central

The mechanisms that regulate mitochondrial inheritance are not yet clear, even though it is 100 years since the first description of non-Mendelian genetics. Here, we quantified the copy numbers of mitochondrial DNA (mtDNA) in the gametic cells of angiosperm species. We demonstrate that each egg cell from Arabidopsis thaliana, Antirrhinum majus, and Nicotiana tabacum possesses 59.0, 42.7, and 73.0 copies of mtDNA on average, respectively. These values are equivalent to those in Arabidopsis mesophyll cells, at 61.7 copies per cell. On the other hand, sperm or generative cells from Arabidopsis, A. majus, and N. tabacum possess minor amounts of mtDNA, at 0.083, 0.47, and 1 copy on average, respectively. We further reveal a 50-fold degradation of mtDNA during pollen development in A. majus. In contrast, markedly high levels of mtDNA are found in the male gametic cells of Cucumis melo and Pelargonium zonale (1296.3 and 256.7 copies, respectively). Our results provide direct evidence for mitochondrial genomic insufficiency in the eggs and somatic cells and indicate that a male gamete of an angiosperm may possess mtDNA at concentrations as high as 21-fold (C. melo) or as low as 0.1% (Arabidopsis) of the levels in somatic cells. These observations reveal the existence of a strong regulatory system for the male gametic mtDNA levels in angiosperms with regard to mitochondrial inheritance. PMID:20605854

Dancing with Multiple Partners  

NSDL National Science Digital Library

Transmembrane proteins, such as G protein-coupled receptors (GPCRs) and integrins, activate intracellular signaling pathways through interactions with downstream binding partners. Woodside discusses two examples in which GPCRs and integrins interact in a noncompeting manner with more than one partner. The specific GPCR described is the thrombin receptor, in experiments where G protein peptides selectively block signaling through a particular G protein that does not appear to inhibit coupling of the receptor to other G proteins. The second system described is the αIIbβ3 integrin and its activation of the nonreceptor tyrosine kinase Syk. Syk appeared capable of interacting with both the integrin and intracellular domains of immune response receptors, because binding of Syk to the integrin was not inhibited by peptides based on the Syk binding site in immune response receptors. Thus, multiple, noncompeting binding partners add to the complexity of signal transduction outputs from a single receptor complex.

Gamete production patterns, ploidy, and population genetics reveal evolutionary significant units in hybrid water frogs (Pelophylax esculentus)  

PubMed Central

The European water frog Pelophylax esculentus is a natural hybrid between P. lessonae (genotype LL) and P. ridibundus (RR). It reproduces through hybridogenesis, eliminating one parental genome from its germline and producing gametes containing the genome of the other parental species. According to previous studies, this elimination and transmission pattern is very diverse. In mixed populations, where only diploid hybrids (LR) live in sympatry and mate with one or both parental species, the excluded genome varies among regions, and the remaining genome is transmitted clonally to haploid gametes. In all-hybrid populations consisting of diploid (LR) and triploid (LLR and/or LRR) frogs, diploid individuals also produce gametes clonally (1n in males, 2n in females), whereas triploids eliminate the genome they have in single copy and produce haploid gametes containing the recombined other genome. However, here, too, regional differences seem to exist, and some triploids have been reported to produce diploid gametes. In order to systematically study such regional and genotype differences in gamete production, their potential origin, and their consequences for the breeding system, we sampled frogs from five populations in three European countries, performed crossing experiments, and investigated the genetic variation through microsatellite analysis. For four populations, one in Poland, two in Germany, and one in Slovakia, our results confirmed the elimination and transmission pattern described above. In one Slovakian population, however, we found a totally different pattern. Here, triploid males (LLR) produce sperm with a clonally transmitted diploid LL genome, rather than a haploid recombined L genome, and LR females clonally produce haploid R eggs, rather than diploid LR eggs. These differences among the populations in gamete production go along with differences in genomotype composition, breeding system (i.e., the way triploids are produced), and genetic variation. These differences are strong evidence for a polyphyletic origin of triploids. Moreover, our findings shed light on the evolutionary potential inherent to the P. esculentus complex, where rare events due to untypical gametogenetic processes can lead to the raise, the perpetuation, and the dispersion of new evolutionary significant lineages which may also deserve special conservation measures.

Active DNA Demethylation in Plant Companion Cells Reinforces Transposon Methylation in Gametes  

PubMed Central

The Arabidopsis thaliana central cell, the companion cell of the egg, undergoes DNA demethylation before fertilization, but the targeting preferences, mechanism, and biological significance of this process remain unclear. Here, we show that active DNA demethylation mediated by the DEMETER DNA glycosylase accounts for all of the demethylation in the central cell and preferentially targets small, AT-rich, and nucleosome-depleted euchromatic transposable elements. The vegetative cell, the companion cell of sperm, also undergoes DEMETER-dependent demethylation of similar sequences, and lack of DEMETER in vegetative cells causes reduced small RNA–directed DNA methylation of transposons in sperm. Our results demonstrate that demethylation in companion cells reinforces transposon methylation in plant gametes and likely contributes to stable silencing of transposable elements across generations.

To give or sell human gametes - the interplay between pragmatics, policy and ethics  

PubMed Central

The ever-growing acceptance and use of assisted human reproduction techniques has caused demand for "donated" sperm and eggs to outstrip supply. Medical professionals and others argue that monetary reward is the only way to recruit sufficient numbers of "donors". Is this a clash between pragmatics and policy/ethics? Where monetary payments are the norm, alternative recruitment strategies used successfully elsewhere may not have been considered, nor the negative consequences of commercialism on all participants thought through. Considerations leading some countries to ban the buying and selling of sperm, eggs and embryos are outlined and a case made that the collective welfare of all involved parties be the primary consideration in this, at times heated, debate.

Children Conceived by Gamete Donation: Psychological Adjustment and Mother-child Relationships at Age 7  

PubMed Central

An increasing number of babies are being born using donated sperm, where the child lacks a genetic link to the father, or donated eggs, where the child lacks a genetic link to the mother. This study examined the impact of telling children about their donor conception on mother-child relationships and children’s psychological adjustment. Assessments of maternal positivity, maternal negativity, mother-child interaction and child adjustment were administered to 32 egg donation, 36 donor insemination and 54 natural conception families with a 7-year-old child. Although no differences were found for maternal negativity or child adjustment, mothers in non-disclosing gamete donation families showed less positive interaction than mothers in natural conception families suggesting families may benefit from openness about the child’s genetic origins.

Comparative cryobiological traits and requirements for gametes and gonadal tissues collected from wildlife species.  

PubMed

A major challenge to retaining viability of frozen gametes and reproductive tissues is to understand and overcome species-specificities, especially because there is substantial diversity in cryobiological properties and requirements among cell types and tissues. Systematic studies can lead to successful post-thaw recovery, especially after determining: 1) membrane permeability to water and cryoprotectant, 2) cryoprotectant toxicity, 3) tolerance to osmotic changes, and 4) resistance to cooling and freezing temperatures. Although species-dependency ultimately dictates the ability of specific cells and tissues to survive freeze-thawing, there are commonalities between taxa that allow a protocol developed for one species to be useful information for another. This is the reason for performing comparative cryopreservation studies among diverse species. Our laboratory has compared cellular cryotolerance, especially in spermatozoa, in a diverse group of animals-from corals to elephants-for more than 30 yrs. Characterizing the biophysical traits of gametes and tissues is the most efficient way to develop successful storage and recovery protocols, but, such data are only available for a few laboratory, livestock, and fish species, with virtually all others (wild mammals, birds, reptiles, and amphibians) having gone unstudied. Nonetheless, when a rare animal unexpectedly dies, there is no time to understand the fundamentals of biophysics. In these emergencies, it is necessary to rely on experience and the best data from taxonomically-related species. Fortunately, there are some general similarities among most species, which, for example, allow adequate post-thaw viability. Regardless, there is a priority for more information on biophysical traits and freezing tolerance of distinctive biomaterials, especially for oocytes and gonadal tissues, and even for common, domesticated animals. Our colleague, Dr John Critser was a pioneer in cryobiology, earning that moniker because of his advocacy and devotion to understanding the differences (and similarities) among species to better store living genetic material.

DNA damage response in male gametes of Cyrtanthus mackenii during pollen tube growth  

PubMed Central

Male gametophytes of plants are exposed to environmental stress and mutagenic agents during the double fertilization process and therefore need to repair the DNA damage in order to transmit the genomic information to the next generation. However, the DNA damage response in male gametes is still unclear. In the present study, we analysed the response to DNA damage in the generative cells of Cyrtanthus mackenii during pollen tube growth. A carbon ion beam, which can induce DNA double-strand breaks (DSBs), was used to irradiate the bicellular pollen, and then the irradiated pollen grains were cultured in a liquid culture medium. The male gametes were isolated from the cultured pollen tubes and used for immunofluorescence analysis. Although inhibitory effects on pollen tube growth were not observed after irradiation, sperm cell formation decreased significantly after high-dose irradiation. After high-dose irradiation, the cell cycle progression of generative cells was arrested at metaphase in pollen mitosis II, and phosphorylated H2AX (?H2AX) foci, an indicator of DSBs, were detected in the majority of the arrested cells. However, these foci were not detected in cells that were past metaphase. Cell cycle progression in irradiated generative cells is regulated by the spindle assembly checkpoint, and modification of the histones surrounding the DSBs was confirmed. These results indicate that during pollen tube growth generative cells can recognize and manage genomic lesions using DNA damage response pathways. In addition, the number of generative cells with ?H2AX foci decreased with culture prolongation, suggesting that the DSBs in the generative cells are repaired. PMID:23550213

Effects of an oil production effluent on gametogenesis and gamete performance in the purple sea urchin (Strongylocentrotus purpuratus Stimpson)  

SciTech Connect

Adult organisms subjected to chronic discharges from a point source of pollution may exhibit several sublethal responses. One such response is the impairment of gamete production. This may be expressed in the amount and/or quality of gametes produced by adults. In this study the effects of chronic exposure to produced water (an oil production effluent) on the gametogenesis and gamete performance of the purple sea urchin (Strongylocentrotus purpuratus Stimpson) were examined using an in situ caging experiment. Adult purple sea urchins were kept in benthic cages arrayed down-field from a discharging diffuser at 13 sites, with distances ranging from 5 to 1,000 m. Cage exposures were maintained in the field for eight weeks, and each cage held 25 animals. Gametogenesis was examined for each sex by comparing a size-independent measure of relative gonads ass as determined by analysis of covariance. Results showed that there was a significant negative relationship between these estimates of relative gonad mass and distance from the outfall for both sexes, indicating that sea urchins living closer to the outfall produced significantly larger gonads. Gamete performance was measured through a fertilization kinetics bioassay that held the concentration of eggs constant and varied the amount of sperm added. The proportion of eggs fertilized under each sperm concentration was determined and the response fit to a model of fertilizability showed a positive relationship with distance away from the outfall. These findings indicate that although adult sea urchins exposed to a produced water outfall exhibit larger gonads, they suffer a marked decrease in a gamete performance.

Predictability of Conversation Partners  

NASA Astrophysics Data System (ADS)

Recent developments in sensing technologies have enabled us to examine the nature of human social behavior in greater detail. By applying an information-theoretic method to the spatiotemporal data of cell-phone locations, [C. Song , ScienceSCIEAS0036-8075 327, 1018 (2010)] found that human mobility patterns are remarkably predictable. Inspired by their work, we address a similar predictability question in a different kind of human social activity: conversation events. The predictability in the sequence of one’s conversation partners is defined as the degree to which one’s next conversation partner can be predicted given the current partner. We quantify this predictability by using the mutual information. We examine the predictability of conversation events for each individual using the longitudinal data of face-to-face interactions collected from two company offices in Japan. Each subject wears a name tag equipped with an infrared sensor node, and conversation events are marked when signals are exchanged between sensor nodes in close proximity. We find that the conversation events are predictable to a certain extent; knowing the current partner decreases the uncertainty about the next partner by 28.4% on average. Much of the predictability is explained by long-tailed distributions of interevent intervals. However, a predictability also exists in the data, apart from the contribution of their long-tailed nature. In addition, an individual’s predictability is correlated with the position of the individual in the static social network derived from the data. Individuals confined in a community—in the sense of an abundance of surrounding triangles—tend to have low predictability, and those bridging different communities tend to have high predictability.

The comparative effectiveness of Integrated treatment for Substance abuse and Partner violence (I-StoP) and substance abuse treatment alone: a randomized controlled trial  

PubMed Central

Background Research has shown that treatments that solely addressed intimate partner violence (IPV) perpetration were not very effective in reducing IPV, possibly due to neglecting individual differences between IPV perpetrators. A large proportion of IPV perpetrators is diagnosed with co-occurring substance use disorders and it has been demonstrated that successful treatment of alcohol dependence among alcohol dependent IPV perpetrators also led to less IPV. The current study investigated the relative effectiveness of Integrated treatment for Substance abuse and Partner violence (I-StoP) to cognitive behavioral treatment addressing substance use disorders including only one session addressing partner violence (CBT-SUD+) among patients in substance abuse treatment who repeatedly committed IPV. Substance use and IPV perpetration were primary outcome measures. Method Patients who entered substance abuse treatment were screened for IPV. Patients who disclosed at least 7 acts of physical IPV in the past year (N?=?52) were randomly assigned to either I-StoP or CBT-SUD+. Patients in both conditions received 16 treatment sessions. Substance use and IPV perpetration were assessed at pretreatment, halfway treatment and posttreatment in blocks of 8 weeks. Both completers and intention-to-treat (ITT) analyses were performed. Results Patients (completers and ITT) in both conditions significantly improved regarding substance use and IPV perpetration at posttreatment compared with pretreatment. There were no differences in outcome between conditions. Completers in both conditions almost fully abstained from IPV in 8 weeks before the end of treatment. Conclusions Both I-StoP and CBT-SUD+ were effective in reducing substance use and IPV perpetration among patients in substance abuse treatment who repeatedly committed IPV and self-disclosed IPV perpetration. Since it is more cost and time-effective to implement CBT-SUD+ than I-StoP, it is suggested to treat IPV perpetrators in substance abuse treatment with CBT-SUD+.

Epithelial cadherin is present in bovine oviduct epithelial cells and gametes, and is involved in fertilization-related events.  

PubMed

Fertilization is a calcium-dependent process that involves sequential cell-cell adhesion events of spermatozoa with oviduct epithelial cells (OECs) and with cumulus-oocyte complexes (COCs). Epithelial cadherin (E-cadherin) participates in calcium-dependent somatic cell adhesion; the adaptor protein ?-catenin binds to the E-cadherin cytoplasmic domain and links the adhesion protein to the cytoskeleton. The study was conducted to immunodetect E-cadherin and ?-catenin in bovine gametes and oviduct (tissue sections and OEC monolayers), and to assess E-cadherin participation in fertilization-related events. Epithelial cadherin was found in spermatozoa, oocytes, cumulus cells, and OEC. In acrosome-intact noncapacitated spermatozoa, E-cadherin was mainly localized in the apical ridge and acrosomal cap (E1-pattern; 84 ± 9%; mean ± standard deviation of the mean). After sperm treatment with heparin to promote capacitation, the percentage of cells with E1-pattern (56 ± 12%) significantly decreased; concomitantly, the percentage of spermatozoa depicting an E-cadherin staining pattern similar to E1-pattern but showing a signal loss in the acrosomal cap (E2-pattern: 40 ± 11%) increased. After l-?-lysophosphatidylcholine-induced acrosome reaction, E-cadherin signal was mainly localized in the inner acrosomal membrane (E3-pattern: 67 ± 22%). In IVM COC, E-cadherin was immunodetected in the plasma membrane of cumulus cells and oocytes, but was absent in the polar body. The 120 KDa mature protein form was found in protein extracts from spermatozoa, oocytes, cumulus cells, and OEC. ?-Catenin distribution followed E-cadherin's in all cells evaluated. Epithelial cadherin participation in cell-cell interaction was evaluated using specific blocking monoclonal antibody DECMA-1. Sperm incubation with DECMA-1 impaired sperm-OEC binding (the number of sperm bound to OEC: DECMA-1 = 6.7 ± 6.1 vs. control = 29.6 ± 20.1; P < 0.001), fertilization with COC (% fertilized COC: DECMA-1 = 68.8 ± 10.4 vs. control = 90.7 ± 3.1; P < 0.05) or denuded oocytes (% fertilized oocytes: DECMA-1 = 57.0 ± 15.2 vs. control = 89.2 ± 9.8; P < 0.05) and binding to the oolemma (the number of sperm bound to oolemma: DECMA-1 = 2.2 ± 1.1 vs. control = 11.1 ± 4.8; P < 0.05). This study describes, for the first time, the presence of E-cadherin in bovine spermatozoa, COC, and OEC, and shows evidence of its participation in sperm interaction with the oviduct and the oocyte during fertilization.

Gamete ripening and hormonal correlates in three strains of lake trout  

USGS Publications Warehouse

In our 2-year laboratory study of hatchery-reared adult lake trout Salvelinus namaycush of the Seneca Lake, Marquette (Lake Superior Lean), and Jenny Lake strains, we compared gamete ripening times and changes in plasma concentrations of seven hormones. If interstrain differences in these traits were found, such differences might help explain the apparent failure of stocked fish of these strains to develop large, naturally reproducing populations in the Great Lakes. The complex temporal changes in plasma hormone levels that occur during sexual maturation in lake trout have not been previously described. We detected little evidence of temporal isolation that would prevent interbreeding among the three strains. Strain had no effect on ovulation date (OD) in either year. Strain did not affect spermiation onset date (SOD) in year 1 but did in year 2, when the mean SOD of Jenny Lake males was earlier than that of Seneca Lake males but not different from that of Marquette males. Hormonal data were normalized around ODs for individual females and SODs for individual males. In females, estradiol-17beta (E2) was highest 8 weeks before the OD; the highest testosterone (T) level occurred 6 weeks before the OD, and the next highest level occurred simultaneously with the highest level of 11-ketotestosterone (11-KT) 2 weeks before the OD. Plasma levels of 17alpha-hydroxy-20beta-dihydroprogesterone (DHP) peaked 1 week before the OD, then abruptly declined immediately after. Cortisol (F), triiodothyronine (T3), and thyroxine (T4) were highly variable, but F was the only hormone that showed no trend with week in either year. In males, plasma E2 levels were highest 3 weeks before the SOD, highest levels of T and of 11-KT occurred simultaneously 2 weeks after the SOD, and DHP peaked 5 weeks after the SOD and 3 weeks after the highest levels of T and 11-KT. As in females, plasma levels of F, T3, and T4 were highly variable, and F was the only hormone that showed no trend with week in either year. Strain had no effect on any hormones in females and only on T and F in males. The lack of pronounced interstrain differences in gamete ripening dates and reproductive endocrinology and the similarity of the temporal patterns and relative concentrations of hormones to those reported for other salmonids suggest nothing unusual or dysfunctional about these reproductive traits that would impede lake trout rehabilitation in the Great Lakes.

Since Chaet and his co-workers (Chaet and McConnaughy, 1959 ; Chaet and Musick, 1960 ; Chaet, l964a) discovered that starfish (Asterias forbesi) can be induced to spawn by injecting a water extract of radial nerves into the coelomic cavity, some clue to the elucidation of the mechanism of starfish spawning has been afforded.

"He won't be my son": Middle Eastern Muslim men's discourses of adoption and gamete donation.  

PubMed

In the Sunni Muslim world, religious mandates prohibit both adoption and gamete donation as solutions to infertility, including in the aftermath of in vitro fertilization (IVF) failures. However, both of these options are now available in two Middle Eastern countries with significant Shi'ite Muslim populations (Iran and Lebanon). On the basis of fieldwork in multisectarian Lebanon, I examine in this article attitudes toward both adoption and gamete donation among childless Muslim men who are undertaking IVF with their wives. No matter the religious sect, most Muslim men in Lebanon continue to resist both adoption and gamete donation, arguing that such a child "won't be my son". However, against all odds, some Muslim men are considering and undertaking these alternatives to family formation as ways to preserve their loving marriages, satisfy their fatherhood desires, and challenge religious dictates, which they view as out of step with new developments in science and technology. Thus, in this article I examine the complicated intersections of religion, technology, marriage, and parenthood in a part of the world that is both poorly understood and negatively stereotyped, particularly in the aftermath of September 11, 2001.

Would 'all-inclusive' compensation attract more gamete donors to balance their loss of anonymity?  

PubMed

The UK Government has determined that children born from egg donation have the same right to know their biological parent as adopted children on reaching the age of 18. There is concern as to the effect of loss of anonymity on egg donor recruitment, since a wait of 1 or 2 years is not unusual even under present circumstances. Some fertility programmes have introduced egg-sharing (involving 'subfertile donors') to circumvent the delays. However, with this method both the donor and the recipient may have reduced overall success. The shortage of sperm donors has led the Human Fertilisation and Embryology Authority (HFEA) to consider increasing the allowable expenses payment and a consultation exercise is underway to review payments and other issues for sperm, egg and embryo donors. Fundamental new initiatives regarding gamete donation need to be implemented to avoid further restrictions on an already unsatisfactory service. An 'all-inclusive' financial allowance is proposed for donors to promote donor recruitment and shorten the waiting time to treatment predicted to increase with the loss of anonymity. PMID:15820032

Transfer of intracolonial genetic variability through gametes in Acropora hyacinthus corals  

NASA Astrophysics Data System (ADS)

In recent years, the new phenomenon of intracolonial genetic variability within a single coral colony has been described. This connotes that coral colonies do not necessarily consist of only a single genotype, but may contain several distinct genotypes. Harboring more than one genotype could improve survival under stressful environmental conditions, e.g., climate change. However, so far it remained unclear whether the intracolonial genetic variability of the adult coral is also present in the gametes. We investigated the occurrence of intracolonial genetic variability in 14 mature colonies of the coral Acropora hyacinthus using eight microsatellite loci. A grid was placed over each colony before spawning, and the emerging egg/sperm bundles were collected separately in each grid. The underlying tissues as well as the egg/sperm bundles were genotyped to determine whether different genotypes were present. Within the 14 mature colonies, we detected 10 colonies with more than one genotype (intracolonial genetic variability). Four out of these 10 mature colonies showed a transfer of different genotypes via the eggs to the next generation. In two out of these four cases, we found additional alleles, and in the two other cases, we found only a subset of alleles in the unfertilized eggs. Our results suggest that during reproduction of A. hyacinthus, more than one genotype per colony is able to reproduce. We discuss the occurrence of different genotypes within a single coral colony and the ability for those to release eggs which are genetically distinct.

First evidence of prothymosin ? localization in the acrosome of mammalian male gametes.  

PubMed

Prothymosin ? (PTMA) is a highly acidic intrinsically unstructured protein. Its expression in male gonads is evolutionary conserved; in rat testis it is specifically localized in the cytoplasm of post-meiotic germ cells, in association with the developing acrosome system. In the present paper we investigated on PTMA localization inside the head of mammalian spermatozoa (SPZ). We chose a confocal approach to ascertain whether PTMA is expressed in the acrosome or in the perinuclear theca, two regions that are tightly linked and partially overlapped in the mature haploid cells. The obtained results showed that PTMA is specifically localized in the acrosome of rat epididymal SPZ; the same experimental approach evidenced, for the first time, PTMA presence in human ejaculated SPZ. A Western blot analysis on protein extracts from human sperm head fractions confirmed the confocal data and demonstrated that the peptide is specifically associated with the inner acrosomal membrane fraction. Finally, when the acrosome reaction was induced in vitro by progesterone treatment on both rat and human sperm, PTMA signal was retained in the apical region of reacted SPZ. In conclusion, this study confirms the conservation of PTMA distribution in vertebrate male gametes and strongly supports a role for this polypeptide in their physiology. PMID:23359453

Mental Health Consequences of Intimate Partner Abuse  

PubMed Central

Battered women are exposed to multiple forms of intimate partner abuse. This article explores the independent contributions of physical violence, sexual coercion, psychological abuse, and stalking on symptoms of posttraumatic stress disorder (PTSD) and depression among a sample of 413 severely battered, help-seeking women. The authors test the unique effects of psychological abuse and stalking on mental health outcomes, after controlling for physical violence, injuries, and sexual coercion. Mean scores for the sample fall into the moderate to severe range for PTSD and within the moderate category for depression scores. Hierarchical regressions test the unique effects of stalking and psychological abuse, after controlling for physical violence, injuries, and sexual coercion. Psychological abuse and stalking contribute uniquely to the prediction of PTSD and depression symptoms, even after controlling for the effects of physical violence, injuries, and sexual coercion. Results highlight the importance of examining multiple dimensions of intimate partner abuse. PMID:18535306

Serostatus disclosure to sexual partners among people living with HIV: examining the roles of partner characteristics and stigma.  

PubMed

HIV serostatus disclosure among people living with HIV/AIDS (PLWHA) is an important component of preventing HIV transmission to sexual partners. Due to barriers like stigma, however, many PLWHA do not disclose their serostatus to all sexual partners. This study explored differences in HIV serostatus disclosure based on sexual behavior subgroup (men who have sex with men [MSM]; heterosexual men; and women), characteristics of the sexual relationship (relationship type and HIV serostatus of partner), and perceived stigma. We examined disclosure in a sample of 341 PLWHA: 138 MSM, 87 heterosexual men, and 116 heterosexual women who were enrolled in SafeTalk, a randomized, controlled trial of a safer sex intervention. We found that, overall, 79% of participants disclosed their HIV status to all sexual partners in the past 3 months. However, we found important differences in disclosure by subgroup and relationship characteristics. Heterosexual men and women were more likely to disclose their HIV status than MSM (86%, 85%, and 69%, respectively). Additionally, disclosure was more likely among participants with only primary partners than those with only casual or both casual and primary partners (92%, 54%, and 62%, respectively). Participants with only HIV-positive partners were also more likely to disclose than those with only HIV-negative partners, unknown serostatus partners, or partners of mixed serostatus (96%, 85%, 40%, and 60%, respectively). Finally, people who perceived more HIV-related stigma were less likely to disclose their HIV serostatus to partners, regardless of subgroup or relationship characteristics. These findings suggest that interventions to help PLWHA disclose, particularly to serodiscordant casual partners, are needed and will likely benefit from inclusion of stigma reduction components.

Effect of Temperature on gametogenesis and gamete quality in brown trout, Salmo trutta.  

PubMed

During the prespawning and spawning season experimental groups of +2 year male and female brown trout, Salmo trutta, were kept under natural photoperiod and at three temperature regimes, a naturally fluctuating one with an average temperature of 7.4 ± 4.6°C as typical for alpine and prealpine river systems (T1), a naturally fluctuating one elevated for circa 5°C to 12.4 ± 5.3°C (T2), and a constant one of 9.6 ± 0.8°C (T3). The effect of the three temperature regimes on the timing of spermiation and ovulation, on the maturation rate of males and females and on physiological and biochemical parameters of spermatozoa and oocytes were investigated. T1 was the optimal one for maturation of males and females. Under these conditions >70% of males produced semen of high quality (defined by a volume >3.5 mL, a motility rate >65%, a swimming velocity >135 µm/sec, and a fertility >65%) for a period of 4 weeks. Females ovulated synchronously and the oocytes were of high quality, too (fertility >80%). In T2 the peak in the percentage of mature males was delayed and shortened, the percentage of spermatozoa with DNA damages increased, and peroxidase and lysozyme activity decreased which are indicative for a decrease in semen quality. In females the time point of ovulation was delayed, the fertility of oocytes was reduced, and their phospholipid and free fatty acids levels were decreased. In T3 maturation of fish was not synchronized. However, no negative effect on gamete quality was observed. PMID:23315835

Expression of a type B RIFIN in Plasmodium falciparum merozoites and gametes  

PubMed Central

Background The ability of Plasmodium falciparum to undergo antigenic variation, by switching expression among protein variants encoded by multigene families, such as var, rif and stevor, is key to the survival of this parasite in the human host. The RIFIN protein family can be divided into A and B types based on the presence or absence of a 25 amino acid motif in the semi-conserved domain. A particular type B RIFIN, PF13_0006, has previously been shown to be strongly transcribed in the asexual and sexual stages of P. falciparum in vitro. Methods Antibodies to recombinant PF13_0006 RIFIN were used in immunofluorescence and confocal imaging of 3D7 parasites throughout the asexual reproduction and sexual development to examine the expression of PF13_0006. Furthermore, reactivity to recombinant PF13_0006 was measured in plasma samples collected from individuals from both East and West African endemic areas. Results The PF13_0006 RIFIN variant appeared expressed by both released merozoites and gametes after emergence. 7.4% and 12.1% of individuals from East and West African endemic areas, respectively, carry plasma antibodies that recognize recombinant PF13_0006, where the antibody responses were more common among older children. Conclusions The stage specificity of PF13_0006 suggests that the diversity of RIFIN variants has evolved to provide multiple specialized functions in different stages of the parasite life cycle. These data also suggest that RIFIN variants antigenically similar to PF13_0006 occur in African parasite populations. PMID:23259643

Production of Polyploids and Unreduced Gametes in Lilium auratum x L. henryi Hybrid  

PubMed Central

Intergenomic F1 hybrids between L. auratum x L. henryi and their BC1 progeny were investigated through genomic in situ hybridization technique (GISH) to determine their potential value in lily breeding. We confirmed that F1 intergenomic hybrids possessed a set of chromosomes (x=12) from both parents and that flowers of the F1 auratum × henryi hybrid showed an intermediate morphological phenotype. Pollen size, viability and germination ability were measured through microscopic observations. F1 intergenomic hybrids produced a relevant frequency of 2n-gametes, which were successfully used to perform crosses with Oriental hybrids, resulting in the triploid Oriental Auratum Henryi (OAuH) hybrid. Twenty BC1 plants were generated by crossing between four different Oriental hybrid cultivars and F1 AuH hybrids using an in vitro embryo rescue technique, after which the genome constitution and chromosome composition were analyzed by GISH. All plants were triploid, showing 12 from female parents (diploid Oriental hybrid) and 24 from male parents (diploid F1 AuH hybrid). Overall, 16 out of 20 BC1 progeny possessed recombinant chromosomes with 1-5 crossover sites per plant. Cytological analysis of 20 BC1 plants by GISH verified that the occurrence of 2n pollen formation in all F1 AuH hybrids was derived from the FDR (first division restitution) mechanism, in which the genome composition of all BC1 plants possess 12 Oriental + 12 L. auratum + 12 L. henryi chromosomes. Allotriploids derived from the AuH hybrid were used as female for crossing with the diploid Oriental hybrid cultivar 'Sorbonne' and considerable numbers of plants (0-6.5 plants per ovary) were only obtained when female OAuH (BC1) triploids were used. Taken together, the results of this study indicate that production and analysis of F1 AuH hybrids and their progeny through sexual polyploidization can be useful for efficient creation of important horticultural traits.

Passive Smoking Exposure from Partners as a Risk Factor for ER+/PR+ Double Positive Breast Cancer in Never-Smoking Chinese Urban Women: A Hospital-Based Matched Case Control Study  

PubMed Central

Background The relationship between passive smoking exposure (PSE) and breast cancer risk is of major interest. Objective To evaluate the relationship between PSE from partners and breast cancer risk stratified by hormone-receptor (HR) status in Chinese urban women population. Design Hospital-based matched case control study. Setting Chinese urban breast cancer patients without current or previous active smoking history in China Medical University 1st Hospital, Liaoning Province, China between Jan 2009 and Nov 2009. Patients Each breast cancer patient was matched 1?1 with healthy controls by gender and age (±2 years) from the same hospital. Measurements The authors used unconditional logistic regression analyses to estimate odds ratio for women with PSE from partners and breast cancer risk. Results 312 pairs were included in the study. Women who endured PSE had significantly increased risk of breast cancer (adjusted OR: 1.46; 95% CI: 1.05–2.03; P?=?0.027), comparing with unexposed women. Women who exposed to >5 cigarettes/day also had significant increased risk (adjusted OR: 1.99; 95% CI: 1.28–3.10; P?=?0.002), as were women exposed to passive smoke for 16–25 years (adjusted OR: 1.87 95% CI: 1.22–2.86; P?=?0.004), and those exposed to > 4 pack-years (adjusted OR: 1.71 95% CI: 1.17–2.50; P?=?0.004). Similar trends were significant for estrogen receptor (ER)/progesterone receptor (PR) double positive subgroup(adjusted OR: 1.71; 2.20; 1.99; 1.92, respectively), but not for ER+/PR?, ER?/PR+, or ER?/PR? subgroups. Limitations limitations of the hospital-based retrospective study, lack of information on entire lifetime PSE and low statistical power. Conclusions Our findings provide further evidence that PSE from partners contributes to increased risk of breast cancer, especially for ER/PR double positive breast cancer, in Chinese urban women.

Intimate partner violence and mental health in Bolivia  

PubMed Central

Background Latin America has among the highest rates of intimate partner violence. While there is increasing evidence that intimate partner violence is associated with mental health problems, there is little such research for developing countries. The purpose of this paper is to examine the relationship between Bolivian women’s experiences with physical, psychological, and sexual intimate partner violence and mental health outcomes. Methods This study analyzes data from the 2008 Bolivia Demographic and Health Survey. 10,119 married or cohabiting women ages 15–49 are included in the analysis. Probit regression models are used to assess the association between intimate partner violence and mental health, after controlling for other demographic factors and partner characteristics. The questionnaire uses selected questions from the SRQ-20 to measure symptoms of mental health problems. Results Intimate partner violence is common in Bolivia, with 47% of women experiencing some type of spousal abuse in the 12 months before the survey. Women exposed to physical spousal violence in the past year are more likely to experience symptoms of depression, anxiety, psychogenic non-epileptic seizures, and psychotic disorders, after controlling for other demographic and partner characteristics. Women who experienced sexual abuse by a partner are most likely to suffer from all mental health issues. Psychological abuse is also associated with an increased risk of experiencing symptoms of depression, anxiety, and psychogenic seizures. Women who experienced only psychological abuse report mental health problems similar to those who were physically abused. Conclusion This study demonstrates an urgent need for research on the prevalence and health consequences of psychological abuse in developing countries. Our findings highlight the need for mental health services for victims of intimate partner violence. Because physical and psychological violence are often experienced concurrently, it is recommended that health providers who are treating victims of physical intimate partner violence also screen them for symptoms of potential mental health problems and refer them to appropriate mental health services.

In-vitro fertilization, gamete donation and surrogacy: perceptions of women attending an infertility clinic in Ibadan, Nigeria.  

PubMed

Infertility affects 20% of couples in Nigeria. Assisted reproductive techniques (ART) offered in Nigeria include in-vitro fertilization (IVF), gamete donation and surrogacy. This cross-sectional questionnaire study aimed at assessing the acceptability of ART to women seeking infertility treatment at the University College Hospital, Ibadan, Nigeria. Of the 307 respondents, 58.3% were aware of IVF and 59.3% would accept it as treatment; 35.2% would accept donor eggs and 24.7% would accept donor sperms-a smaller proportion anticipated acceptability by their husbands. Thirty five percent were aware of surrogacy, 37.8% would accept it as treatment; most preferring a stranger as a surrogate. Most felt surrogates should not be paid. Acceptance of ART was associated with older age, longer duration of infertility, previous failed treatment and women without other children. As chances of successful pregnancy are improved in younger individuals, counselling towards overcome barriers to accepting gamete donation and surrogacy should be instituted early. PMID:25022149

Performance of non-motile male gametes in the sea: analysis of paternity and fertilization success in a natural population of a red seaweed, Gracilaria gracilis  

PubMed Central

In haploid–diploid red seaweeds, the dispersal of male gametes is presumed limited due to their lack of flagella. It has been suggested that this group suffers from sperm limitation and, consequently, that fertilization is relatively inefficient. Fertilization in most floridean rhodophytes results in the formation a cystocarp, a swelling on the haploid female thallus housing the diploid zygote and its thousands of diploid daughter spores. To study the performance of non-motile male gametes in the sea, we evaluated both female and male fertilization success in a natural population of the red marine alga Gracilaria gracilis. Female fertilization success, estimated by cystocarp yield per unit female thallus, was evaluated with respect to the availability of male gametes. Male fertilization success, estimated by the individual contribution of different males to zygotes, was assessed by paternity analyses on 350 cystocarps produced in one reproductive season using two microsatellite loci. The results show that cystocarp yield is not sperm limited and that the large variation in male fertilization success cannot be solely explained by the distance travelled by the male gamete to find a mate. Taken together, the results suggest that, not only is fertilization efficient, but that male–male competition and/or female choice may play a role in shaping population mating patterns.

Gamete cryobanks for laboratory research: developing a rapid and easy-to-perform protocol for the cryopreservation of the sea urchin Paracentrotus lividus (Lmk, 1816) spermatozoa.  

PubMed

Gamete cryopreservation is a biotechnology that can guarantee a continuous supply of gametes, regardless of the seasonal reproductive cycle. In this study we developed a protocol for the cryopreservation of the sea urchin Paracentrotuslividus spermatozoa, with a view to the creation of cryobanks of semen to be used as a model system in laboratory research and ecotoxicological tests. All the key phases of the procedure were separately considered and the effect on sperm motility was evaluated by means of computer assisted analysis. The best results were obtained using 7% dimethylsulfoxide in 1% NaCl plus 0.04 M trehalose as the extender, at a freezing rate of -20 °C/min. On thawing, in semen samples cryopreserved in accordance with this protocol the velocity parameters of the sub-population of rapid sperm (best performing spermatozoa) did not significantly differ from semen on collection; in addition also the fertilization ability was restored, and about 50% of normal developed plutei larvae were obtained by thawed semen. The developed protocol is rapid and easy-to-perform; moreover, the use of gametes from reared urchins makes it unnecessary to continuously collect specimens from natural populations, making this procedure a promising starting point for the creation of alternative and more sustainable methodologies in laboratory research on sea urchin gametes and embryos.

We apply this understanding to problems posed by escaped farm salmon and measure their potential to reproduce in the wild. Farm Atlantic salmon (Salmo salar) are a threat to biodiversity, because they escape in large numbers and can introgress, dilute or disrupt locally adapted wild gene pools. Experiments at the whole fish level have found farm reproductive potential to be significant, but inferior compared to wild adults, especially for males. Here, we assess reproductive performance at the gamete level through detailed in vitro comparisons of the form, function, fertility, compatibility and competitiveness of farm versus wild Atlantic salmon sperm and eggs, in conditions mimicking the natural gametic microenvironment, using fish raised under similar environmental conditions. Despite selective domestication and reduced genetic diversity, we find functional equivalence in all farm fish gamete traits compared with their wild ancestral strain. Our results identify a clear threat of farm salmon reproduction with wild fish and therefore encourage further consideration of using triploid farm strains with optimized traits for aquaculture and fish welfare, as triploid fish remain reproductively sterile following escape.

Performance of non-motile male gametes in the sea: analysis of paternity and fertilization success in a natural population of a red seaweed, Gracilaria gracilis  

Microsoft Academic Search

In haploid-diploid red seaweeds, the dispersal of male gametes is presumed limited due to their lack of flagella. It has been suggested that this group suffers from sperm limitation and, consequently, that fertilization is relatively inefficient. Fertilization in most floridean rhodophytes results in the formation a cystocarp, a swelling on the haploid female thallus housing the diploid zygote and its

Transcriptomes of isolated Oryza sativa gametes characterized by deep sequencing: evidence for distinct sex-dependent chromatin and epigenetic states before fertilization.  

PubMed

The formation of a zygote by the fusion of egg and sperm involves the two gametic transcriptomes. In flowering plants, the embryo sac embedded within the ovule contains the egg cell, whereas the pollen grain contains two sperm cells inside a supporting vegetative cell. The difficulties of collecting isolated gametes and consequent low recovery of RNA have restricted in-depth analysis of gametic transcriptomes in flowering plants. We isolated living egg cells, sperm cells and pollen vegetative cells from Oryza sativa (rice), and identified transcripts for approximately 36 000 genes by deep sequencing. The three transcriptomes are highly divergent, with about three-quarters of those genes differentially expressed in the different cell types. Distinctive expression profiles were observed for genes involved in chromatin conformation, including an unexpected expression in the sperm cell of genes associated with active chromatin. Furthermore, both the sperm cell and the pollen vegetative cell were deficient in expression of key RNAi components. Differences in gene expression were also observed for genes for hormonal signaling and cell cycle regulation. The egg cell and sperm cell transcriptomes reveal major differences in gene expression to be resolved in the zygote, including pathways affecting chromatin configuration, hormones and cell cycle. The sex-specific differences in the expression of RNAi components suggest that epigenetic silencing in the zygote might act predominantly through female-dependent pathways. More generally, this study provides a detailed gene expression landscape for flowering plant gametes, enabling the identification of specific gametic functions, and their contributions to zygote and seed development.

Treaty verification with an uncertain partner  

SciTech Connect

A simple model is used to analyze the performance of a system for verifying compliance with an arms control treaty. Blue and Red are partners in to a treaty. Blue prefers to comply, but is uncertain whether Red similarly prefers compliance (in the absence of threatened violation detection). Blue's uncertainty is modeled as a probability distribution over three different Red types: Violators, Compilers, and Deterrables. Criteria are derived to determine the level at which Blue should set his detection threshold, and when it is best for Blue not to verify at all. The results involve both game-theoretic and Bayes solutions. 9 refs., 14 figs.

Partners in family planning.  

PubMed

Studies of the Africa OR/TA Project and other Cooperating Agencies suggest that support of family planning by traditional health practitioners (THPs), traditional birth attendants (TBAs), Islamic religious leaders, and male opinion leaders (MOLs) can result in an increase in the availability of family planning services in the community. A study in Kenya shows that 100 trained THPs who were actively involved in family planning (i.e., distributors of condoms, oral contraceptives, and primary health care drugs) increased contraceptive use in Siaya and Kakamega districts from 7% to 15% and from 14% to 34%, respectively. Contraceptive use did not change in the 2 control areas. Two years after TBAs underwent training in family planning promotion, the proportion of women who named TBAs as their source of family planning information increased from 2% to 18%. In The Gambia, integration of Islamic religious leaders into family planning promotion activities resulted in an increase of current modern contraceptive method use from 9% to 20% for males and from 9% to 26% for females. Involvement of 69 MOLs has increased knowledge of family planning methods in Nkambe, Cameroon. For example, among males, knowledge about the condom increased from 52% to 81% and knowledge about spermicides increased from 12% to 44%. The corresponding figures for women were 47% to 72% and 17% to 42%, respectively. PMID:12319039

TEP Power Partners Project [Tucson Electric Power  

SciTech Connect

The Arizona Governor’s Office of Energy Policy, in partnership with Tucson Electric Power (TEP), Tendril, and Next Phase Energy (NPE), formed the TEP Power Partners pilot project to demonstrate how residential customers could access their energy usage data and third party applications using data obtained from an Automatic Meter Reading (AMR) network. The project applied for and was awarded a Smart Grid Data Access grant through the U.S. Department of Energy. The project participants’ goal for Phase I is to actively engage 1,700 residential customers to demonstrate sustained participation, reduction in energy usage (kWh) and cost ($), and measure related aspects of customer satisfaction. This Demonstration report presents a summary of the findings, effectiveness, and customer satisfaction with the 15-month TEP Power Partners pilot project. The objective of the program is to provide residential customers with energy consumption data from AMR metering and empower these participants to better manage their electricity use. The pilot recruitment goals included migrating 700 existing customers from the completed Power Partners Demand Response Load Control Project (DRLC), and enrolling 1,000 new participants. Upon conclusion of the project on November 19, 2013: ? 1,390 Home Area Networks (HANs) were registered. ? 797 new participants installed a HAN. ? Survey respondents’ are satisfied with the program and found value with a variety of specific program components. ? Survey respondents report feeling greater control over their energy usage and report taking energy savings actions in their homes after participating in the program. ? On average, 43 % of the participants returned to the web portal monthly and 15% returned weekly. ? An impact evaluation was completed by Opinion Dynamics and found average participant savings for the treatment period1 to be 2.3% of their household use during this period.2 In total, the program saved 163 MWh in the treatment period of 2013.

Why I Hit Him: Women's Reasons for Intimate Partner Violence  

PubMed Central

This study examines motives for intimate partner violence (IPV) among a community sample of 412 women who used IPV against male partners. A “Motives and Reasons for IPV scale” is proposed, and exploratory factor analyses identified five factors: expression of negative emotions, self-defense, control, jealousy, and tough guise. To our knowledge, the study is the first to investigate the relationship between women’s motives for IPV and their perpetration of physical, psychological, and sexual aggression, as well as coercive control, toward partners. Hierarchical regression analyses revealed participants’ aggression was driven by complex, multiple motives. All five motives were related to a greater frequency of perpetrating IPV. Treatment programs focusing on women’s IPV perpetration should address both defensive and proactive motives. PMID:21072136

Partner-guided cancer pain management at the end of life: a preliminary study.  

PubMed

This preliminary study tested the efficacy of a partner-guided cancer pain management protocol for patients who are at the end of life. Seventy-eight advanced cancer patients meeting criteria for hospice eligibility and their partners were randomly assigned to a partner-guided pain management training intervention, or usual care control condition. The partner-guided pain management training protocol was a three-session intervention conducted in patients' homes that integrated educational information about cancer pain with systematic training of patients and partners in cognitive and behavioral pain coping skills. Data analyses revealed that the partner-guided pain management protocol produced significant increases in partners' ratings of their self-efficacy for helping the patient control pain and self-efficacy for controlling other symptoms. Partners receiving this training also showed a trend to report improvements in their levels of caregiver strain. Overall, the results of this preliminary study suggest that a partner-guided pain management protocol may have benefits in the context of cancer pain at the end of life. Given the significance of pain at the end of life, future research in this area appears warranted. PMID:15781177

Associating pregnancy with partner violence against Chinese women.  

PubMed

The present study discusses if pregnancy is a risk factor for intimate partner violence using a large, representative sample containing detailed information on partner violence including physical and sexual abuse as well as perpetrator-related risk factors. Data from a representative sample of 2,225 men were analyzed. The self-reported prevalence of men's violence against their female partners was computed and compared in terms of demographic, behavioral, and relationship characteristics. The preceding-year prevalence of physical assault, sexual violence, and "any violence or injury" among the group whose partners were pregnant was 11.9%, 9.1%, and 18.8%, respectively. This is significantly higher than the nonpregnant group. Pregnancy was significantly associated with increased odds of violence, including physical assault, sexual violence, and "any violence or injury" (ORs = 2.42, 2.42, and 2.60, respectively). Having controlled for relationship characteristics including social desirability, social support, in-law conflict, dominance, and jealousy of male perpetrators, pregnancy was significantly associated with "any violence or injury." Demographic and behavioral variables accounted for pregnant women's significantly higher odds of having been abused in the year preceding the data collection. This study provides preliminary findings on the association between pregnancy and partner violence. Our findings underscore the need to screen for violence among pregnant women in clinical health care settings as well as in communities. Perpetrator-related risk factors should be included in the assessment of risk for partner violence against pregnant women. For the prevention of intimate partner violence, family-based intervention is needed to work with victims as well as perpetrators. PMID:20495098

Maternal Re-Partnering and New-Partner Fertility: Associations with Nonresident Father Investments in Children.  

PubMed

Research suggests that paternal re-partnering and new-partner fertility are associated with decreased nonresident father investments in children. Few studies, however, have examined the influence of maternal re-partnering and new-partner births on nonresident father investments. We use data from the National Longitudinal Survey of Youth to examine associations of maternal re-partnering (through cohabitation or marriage with a new partner) and new-partner births with nonresident father visitation and child support payments. Results suggest that maternal re-partnering is associated with a decrease in both yearly father-child contact and child support received by the mother. New-partner fertility for mothers who are co-residing with a partner is associated with an additional decrease in monthly father-child contact, but does not have an additional influence on yearly father-child contact or child support receipt.

Partner Characteristics Predicting HIV-1 Set Point in Sexually Acquired HIV-1 Among African Seroconverters  

PubMed Central

Abstract Plasma HIV-1 RNA set point is an important predictor of HIV-1 disease progression. We hypothesized that inoculum size and HIV-1 exposure prior to HIV-1 transmission may modulate set point. We evaluated predictors of set point among 141 African HIV-1 seroconverters and their HIV-1-infected study partners. We compared characteristics of seroconverters and their HIV-1-infected partners and HIV-1 set point. Data were from a clinical trial of genital HSV-2 suppression with acyclovir to reduce HIV-1 transmission in HIV-1 serodiscordant couples with HIV-1 transmission linkage assigned through virus sequencing. Our analysis includes data from all transmissions including those with transmission linkage to the HIV-1-infected “source partner” and those that were not linked to their HIV-1-infected study partner. In multivariable analysis, higher plasma HIV-1 in source partners was associated with higher seroconverter set point (+0.44 log10 copies/ml per log10 source partner plasma HIV-1, p<0.001). In addition, bacterial vaginosis (BV) among female source partners near the time of infection was associated with higher set point in their male seroconverters (+0.49 log10, p=0.04). Source partner characteristics associated with lower set point included male circumcision (?0.63 log10, p=0.03) and assignment to acyclovir (?0.44 log10, p=0.02). The proportion of variation in set point explained by plasma HIV-1 RNA of the source partner, after controlling for other factors, was 0.06. Source partner plasma HIV-1 level is the most significant predictor of seroconverter set point, possibly reflecting characteristics of the transmitted virus. Acyclovir use, BV among women source partners, and circumcision among male source partners may alter the set point by affecting transmitted virus inoculum in the source partners' genital compartment.

Production of functional gametes from cryopreserved primordial germ cells of the Japanese quail.  

PubMed

The Japanese quail (Coturnix japonica) is a valuable bird as both an experimental animal, for a wide range of scientific disciplines, and an agricultural animal, for the production of eggs and meat. Cryopreservation of PGCs would be a feasible strategy for the conservation of both male and female fertility cells in Japanese quail. However, the effects of freeze-thaw treatment on viability, migration ability and germline transmission ability of quail PGCs still remain unclear. In the present study, male and female PGCs were isolated from the blood of 2-day-old embryos, which were cooled by slow freezing and then cryopreserved at -196 C for 77-185 days, respectively. The average recovery rate of PGCs after freeze-thawing was 47.0%. The viability of PGCs in the frozen group was significantly lower than that of the control group (P<0.05) (85.5% vs. 95.1%). Both fresh and Frozen-thawed PGCs that were intravascularly transplanted into recipient embryos migrated toward and were incorporated into recipient gonads, although the number of PGCs settled in the gonads was 48.5% lower in the frozen group than in the unfrozen control group (P<0.05). Genetic cross analysis revealed that one female and two male recipients produced live progeny derived from the frozen-thawed PGCs. The frequency of donor-derived offspring was slightly lower than that of unfrozen controls, but the difference was not significant (4.0 vs. 14.0%). These results revealed that freeze-thaw treatment causes a decrease in viability, migration ability and germline transmission ability of PGCs in quail. PMID:24077020

Gamete therapeutics: recombinant protein adsorption by sperm for increasing fertility via artificial insemination.

A decrease in fertility can have a negative economic impact, both locally and over a broader geographical scope, and this is especially the case with regard to the cattle industry. Therefore, much interest exists in evaluating proteins that might be able to increase the fertility of sperm. Heparin binding proteins (HBPs), specifically the fertility associated antigen (FAA) and the Type-2 tissue inhibitor of metalloproteinase (TIMP-2), act to favor the capacitation and acrosome reaction and perhaps even modulate the immune system's response toward the sperm. The objective of this research was to determine the effect on fertility of adding recombinant FAA (rFAA) and recombinant TIMP-2 (rTIMP-2) to bovine semen before cryopreservation for use in an artificial insemination (AI) program in a tropical environment. For this experiment, 100 crossbred (Bos taurus x Bos indicus) heifers were selected based on their estrus cycle, body condition score (BCS), of 4 to 6 on a scale of 1 to 9, and adequate anatomical conformation evaluated by pelvic and genital (normal) measurements. Heifers were synchronized using estradiol benzoate (EB), Celosil® (PGF2?) (Shering-Plough) and a controlled internal drug release (CIDR) device was inserted that contained progesterone. Inseminations were performed in two groups at random, 50 animals per group. The control group was inseminated with conventional semen. The treatment group was inseminated with semen containing rFAA (25 µg/mL) and rTIMP-2 (25 µg/mL). In the control group a 16% pregnancy rate was obtained versus a 40% pregnancy rate for the HBP treatment group, resulting in a significant difference (P?=?0.0037). Given the results herein, one may conclude that the HBPs can increase fertility and could be an option for cattle in tropical conditions; however, one needs to consider the environment, nutrition, and the genetic interaction affecting the final result in whatever reproductive program that is implemented.

Production of Functional Gametes from Cryopreserved Primordial Germ Cells of the Japanese Quail  

PubMed Central

Abstract The Japanese quail (Coturnix japonica) is a valuable bird as both an experimental animal, for a wide range of scientific disciplines, and an agricultural animal, for the production of eggs and meat. Cryopreservation of PGCs would be a feasible strategy for the conservation of both male and female fertility cells in Japanese quail. However, the effects of freeze-thaw treatment on viability, migration ability and germline transmission ability of quail PGCs still remain unclear. In the present study, male and female PGCs were isolated from the blood of 2-day-old embryos, which were cooled by slow freezing and then cryopreserved at –196 C for 77–185 days, respectively. The average recovery rate of PGCs after freeze-thawing was 47.0%. The viability of PGCs in the frozen group was significantly lower than that of the control group (P<0.05) (85.5% vs. 95.1%). Both fresh and Frozen-thawed PGCs that were intravascularly transplanted into recipient embryos migrated toward and were incorporated into recipient gonads, although the number of PGCs settled in the gonads was 48.5% lower in the frozen group than in the unfrozen control group (P<0.05). Genetic cross analysis revealed that one female and two male recipients produced live progeny derived from the frozen-thawed PGCs. The frequency of donor-derived offspring was slightly lower than that of unfrozen controls, but the difference was not significant (4.0 vs. 14.0%). These results revealed that freeze-thaw treatment causes a decrease in viability, migration ability and germline transmission ability of PGCs in quail. PMID:24077020

The role of adolescent physical abuse in adult intimate partner violence.  

PubMed

This study's primary aims were to examine whether a sample of young adults, aged 23 to 31, who had been documented as physically abused by their parent(s) during adolescence would be more likely to aggress, both physically and verbally, against their intimate partners compared with nonabused young adults and whether abuse history was (along with other risk factors) a significant predictor of intimate partner physical and emotional violence perpetration or victimization. In this longitudinal study, 67 abused and 78 nonabused adults (of an original sample of 198 adolescents) completed the Modified Conflict Tactics Scale and the Jealousy and Emotional Control Scales. Nonabused comparison adolescents were matched for age, gender, and community income. As adults, participants with abuse histories had significantly higher rates of intimate partner physical violence and verbal aggression than did comparison participants. Multivariate logistic regressions indicated that adults with histories of physical abuse were more than twice as likely to be physically violent and almost six times more likely to be verbally aggressive to their intimate partners than were comparison participants. Having had an alcohol use disorder, being married to or living with a partner, and perceiving one's partner as controlling were also significantly associated with physical violence. Jealousy and feeling controlled by one's partner were also significant predictors of verbal aggression. These findings underscore the importance of preventing adolescent abuse as a means of decreasing the incidence of intimate partner physical violence in adulthood. PMID:21602201

Promiscuity of translocation partners in multiple myeloma.  

PubMed

Multiple myeloma (MM) is characterized by karyotypic instability, including chromosomal translocations involving the IGH locus. MM cells display a promiscuity of translocation partners, only some of which are recurrent. We propose that several factors, including temporal and spatial nuclear positioning of potential partner loci, "off-target" IGH diversification mechanisms, and aberrant repair pathways contribute to the promiscuity of translocation partners in MM. We speculate that in MM, IGH diversification processes [V(D)J recombination, somatic hypermutation, and class switch recombination] in B cells may not be restricted to specific stages of B-cell development or within specific immune tissues, but may occur in different temporal "windows." Before or during MM evolution, off-target activities of the enzymes involved in IGH modification processes may contribute to the generation of double-strand breaks (DSB) in translocation partner loci. In the parent B cells from which MM originates, spatial proximity within the nucleus of IGH and potential translocation partners contributes to the selection of a translocation partner and the clinical frequency at which a specific translocation occurs. The spatial proximity of IGH and specific translocation partners may be temporal and contribute not only to partner selection but also to the promiscuity of partners seen in MM. Lastly, aberrant repair mechanisms in MM progenitors (including the possibility that a Ku 86 variant allows for positional instability at DSBs) may also contribute to the promiscuity of chromosome translocation partners in MM.

Intimate Partner Violence among California Couples: Multilevel Analysis of Environmental and Partner Risk Factors  

PubMed Central

This study assessed the extent to which environmental (Census block-group alcohol outlet density, neighborhood demographic characteristics) and partner risk factors (e.g., hazardous drinking, psychosocial characteristics) contribute to the likelihood of intimate partner violence among 1,753 couples residing in 50 medium-to-large California cities. Multilevel logistic regression models were used to analyze the role of alcohol outlets (off-premise outlets, bars/pubs and restaurants), neighborhood demographic characteristics, and partner risk factors in relation to male-to-female partner violence (MFPV) and female-to-male partner violence (FMPV) risk. Approximately 12% of couples reported past-year partner violence. Results showed that none of the environmental measures were related to MFPV or FMPV. Male partner's impulsivity and each partner's adverse childhood experiences were associated with MFPV risk. Risk factors for FMPV were male partner's impulsivity and frequency of intoxication and female partner's adverse childhood experiences. Individual/couple characteristics appear to be the most salient IPV risk factors. The male partner's heavy drinking may lead to negative partner/spousal interactions that result in FMPV. The male partner's impulsivity, and each partner's adverse childhood experiences, may potentiate couple conflict and result in aggression. Interventions that target prevention of family dysfunction during childhood may help reduce interpersonal violence in adulthood. PMID:24812578

Prioritizing partners across the continuum.  

PubMed

With the advent of accountable care organizations, bundled payments, value-based purchasing, and penalties for preventable hospital readmission, tight connections and collaboration across the care continuum will become critical to achieve successful patient outcomes and to reduce the cost of care delivery. Lehigh Valley Health Network (LVHN), the largest provider of health services in eastern Pennsylvania, set out on a journey to build collaborative relationships with skilled nursing facilities (SNFs) in their eastern Pennsylvania community. LVHN desired SNF partners with mutual interests in improving quality of care and lowering costs of delivery where possible. Recognizing that not all SNFs are alike, LVHN developed a Collaborative Partner Prioritization Tool to assess and prioritize skilled nursing facilities in an effort to determine those that would make the best collaborators. SNFs were reviewed based on their volume of mutual patients, quality of care delivery, and their perceived willingness to align with LVHN. Six variables were used to assess these facilities, including (1) patient discharge destination volume by SNF; (2) 30-day all-cause readmission rate to an LVHN hospital; (3) Medicare's Nursing Home Compare 5-Star Overall Rating; (4) the health network affiliation of the SNF's medical director; (5) the level of LVHN-employed or -affiliated physician presence at the SNF; and (6) the SNF's current participation in LVHN-sponsored programs and meetings. Through use of the Collaborative Partner Prioritization Tool, it was discovered that roughly 70% of LVHN patients who required skilled nursing care following their inpatient stay received care at 1 of 20 SNFs. Of these, 5 facilities performed well on the 6-variable assessment, deeming them the "Tier 1 Facilities" to initially focus collaborative efforts. LVHN has strategically deployed physician resources and has increased physician presence at these "Tier 1 SNFs." These facilities have also gained remote read-only access to LVHN's inpatient electronic medical record and have had opportunity to participate in LVHN-sponsored programs. Special projects have been co-developed with several SNFs, including a telemedicine-based Parkinson's disease program to increase patient access to a neurologist specially trained in movement disorders. The Collaborative Partner Prioritization Tool has become a powerful tool when used for prioritization of relationships and allocation of LVHN physicians and resources. Collaboration with strong SNF partners has offered a shared opportunity to improve quality of care, reduce costs, and prepare for the many policies affecting the health care industry. Future outcomes of this work will include quality metrics, such as readmissions, patient satisfaction with care, time for decision to admit, and overall costs of care. The data and metrics used to define the prioritization tool will continue to be adapted as the post-acute market and hospital-SNF relationships continue to evolve. PMID:23018039

The Specification and Global Reprogramming of Histone Epigenetic Marks during Gamete Formation and Early Embryo Development in C. elegans  

PubMed Central

In addition to the DNA contributed by sperm and oocytes, embryos receive parent-specific epigenetic information that can include histone variants, histone post-translational modifications (PTMs), and DNA methylation. However, a global view of how such marks are erased or retained during gamete formation and reprogrammed after fertilization is lacking. To focus on features conveyed by histones, we conducted a large-scale proteomic identification of histone variants and PTMs in sperm and mixed-stage embryo chromatin from C. elegans, a species that lacks conserved DNA methylation pathways. The fate of these histone marks was then tracked using immunostaining. Proteomic analysis found that sperm harbor ?2.4 fold lower levels of histone PTMs than embryos and revealed differences in classes of PTMs between sperm and embryos. Sperm chromatin repackaging involves the incorporation of the sperm-specific histone H2A variant HTAS-1, a widespread erasure of histone acetylation, and the retention of histone methylation at sites that mark the transcriptional history of chromatin domains during spermatogenesis. After fertilization, we show HTAS-1 and 6 histone PTM marks distinguish sperm and oocyte chromatin in the new embryo and characterize distinct paternal and maternal histone remodeling events during the oocyte-to-embryo transition. These include the exchange of histone H2A that is marked by ubiquitination, retention of HTAS-1, removal of the H2A variant HTZ-1, and differential reprogramming of histone PTMs. This work identifies novel and conserved features of paternal chromatin that are specified during spermatogenesis and processed in the embryo. Furthermore, our results show that different species, even those with diverged DNA packaging and imprinting strategies, use conserved histone modification and removal mechanisms to reprogram epigenetic information.

Endocannabinoid influence on partner preference in female rats.  

PubMed

The present study investigated the role of the endocannabinoid system on sexual motivation in the female rat. In Experiment 1, gonadally intact female rats were first tested for partner preference after a vehicle injection. Approximately 2 weeks later, all rats were tested again after an injection of the endocannabinoid antagonist, SR141716 (SR; also known as Rimonabant; 1.0mg/kg). During the first 10 min of each partner preference test, subjects could spend time near either a male or female stimulus animal that was placed behind a wire mesh (No-Contact). During the second 10 min of each partner preference test, subjects had unrestricted access to both stimulus animals (Contact). When the female subjects were treated with SR, they made fewer visits to either stimulus animal during the no-contact phase of the partner preference test compared to when they were treated with vehicle. In Experiment 2, ovariectomized (OVX) subjects primed with estrogen were administered SR or vehicle and tested for partner preference (Experiment 2A). Approximately 2 weeks later, the subjects from the control group were tested again after an injection of SR (Experiment 2B). In contrast to Experiment 1, treatment with SR reduced the number of visits specifically to the male stimulus during the contact phase of the test in Experiment 2. Experiment 3 tested the effects of SR on general locomotion and found no effect of SR on line crossings in an open field. Finally, in Experiment 4, OVX estrogen- and progesterone-primed subjects were administered the endocannabinoid agonist anandamide (AEA: 1.0mg/kg) or vehicle and tested for partner preference. AEA-treated subjects made more visits to the male stimulus than vehicle-treated subjects during the contact phase of the test. The results of the present study suggest that the endocannabinoid system may contribute to sexual motivation in female rats by specifically altering approach behavior. PMID:25042777

Immunocontraceptives: New Approaches to Fertility Control  

PubMed Central

The rapidly increasing global population has bowed the attention of family planning and associated reproductive health programmes in the direction of providing a safe and reliable method which can be used to limit family size. The world population is estimated to exceed a phenomenal 10 billion by the year 2050 A.D., thus presenting a real jeopardy of overpopulation with severe implications for the future. Despite the availability of contraceptive methods, there are over one million elective abortions globally each year due to unintended pregnancies, having devastating impact on reproductive health of women worldwide. This highlights the need for the development of newer and improved contraceptive methods. A novel contraceptive approach that is gaining substantial attention is “immunocontraception” targeting gamete production, gamete outcome, or gamete function. Amongst these, use of sperm antigens (gamete function) seems to be an exciting and feasible approach. However, the variability of immune response and time lag to attain titer among vaccinated individuals after active immunization has highlighted the potential relevance of preformed antibodies in this league. This review is an attempt to analyze the current status and progress of immunocontraceptive approaches with respect to their establishment as a future fertility control agent. PMID:25110702

Leading through partnering: from bedside to community.  

PubMed

Partnering as a means of leading requires a particular focus and has particular characteristics. It is unrealistic to think that every person that participates in a partnership would have honed the skills to provide guidance, strength, and support for the process. It is not likely that every partner understands the collaborative process well enough to engage all partners with tact, openness, fairness, and critical, but respectful, reflection. The characteristics depicted in the Leading Through Partnering dome reflect those leaders who have integrated partnering into a coherent framework of action. Stern (2003), in describing her grounded theory research on "attentive partnering" among colleagues, determined that conditions for partnering seem to require the presence of "determined, persuasive leaders who foster growth-enhancing collegial relationships" (pg. 271). The concept of partnering continues to take hold in many forms. Leading Through Partnering as a variant form, whether occurring on a small scale at the bedside or a large scale in the community, is likely to be more than just a passing trend. PMID:15553062

Actor-partner effects associated with experiencing intimate partner violence or coercion among male couples enrolled in an HIV prevention trial  

PubMed Central

Background Intimate partner violence (IPV) and coercion have been associated with negative health outcomes, including increased HIV risk behaviors, among men who have sex with men (MSM). This is the first study to describe the prevalence and factors associated with experiencing IPV or coercion among US MSM dyads using the actor-partner interdependence model (APIM), an analytic framework to describe interdependent outcomes within dyads. Methods Among MSM couples enrolled as dyads in an HIV prevention randomized controlled trial (RCT), two outcomes are examined in this cross-sectional analysis: 1) the actor experiencing physical or sexual IPV from the study partner in the past 3-months and 2) the actor feeling coerced to participate in the RCT by the study partner. Two multilevel APIM logistic regression models evaluated the association between each outcome and actor, partner, and dyad-level factors. Results Of 190 individuals (95 MSM couples), 14 reported experiencing physical or sexual IPV from their study partner in the past 3 months (7.3%) and 12 reported feeling coerced to participate in the RCT by their study partner (6.3%). Results of multivariate APIM analyses indicated that reporting experienced IPV was associated (p?partner education. Reporting experienced coercion was associated (p?partner education. Conclusions These findings from an HIV prevention RCT for MSM show considerable levels of IPV experienced in the past 3-months and coercion to participate in the research study, indicating the need for screening tools and support services for these behaviors. The identification of factors associated with IPV and coercion demonstrate the importance of considering actor and partner effects, as well as dyadic-level effects, to improve development of screening tools and support services for these outcomes.

The influence of sperm concentration, length of the gamete co-culture and the evolution of different sperm parameters on the in vitro fertilization of prepubertal goat oocytes.  

PubMed

The aims of the present study were: (1) to evaluate the influence of sperm concentration (ranging from 0.5 × 10(6) to 4 × 10(6) spermatozoa/ml) and length of the gamete co-incubation time (2, 4, 6, 8, 10, 12, 16, 20, 24 or 28 h) on in vitro fertilization (IVF), assessing the sperm penetration rate; (2) to investigate the kinetics of different semen parameters as motility, viability and acrosome status during the co-culture period; and (3) to analyse the effect of the presence of cumulus-oocytes complexes (COCs) on these parameters. To achieve these objectives, several experiments were carried out using in vitro matured oocytes from prepubertal goats. The main findings of this work are that: (1) in our conditions, the optimum sperm concentration is 4 × 10(6) sperm/ml, as this sperm:oocyte ratio (approximately 28,000) allowed us to obtain the highest penetration rate, without increasing polyspermy incidence; (2) the highest percentage of viable acrosome-reacted spermatozoa is observed between 8-12 h of gamete co-culture, while the penetration rate is maximum at 12 h of co-incubation; and (3) the presence of COCs seems to favour the acrosome reaction of free spermatozoa on IVF medium, but not significantly. In conclusion, we suggest that a gamete co-incubation for 12-14 h, with a concentration of 4 × 10(6) sperm/ml, would be sufficient to obtain the highest rate of penetration, reducing the exposure of oocytes to high levels of reactive oxygen species produced by spermatozoa, especially when a high sperm concentration is used to increase the caprine IVF outcome.

Communication Partners' Journey through Their Partner's Hearing Impairment  

PubMed Central

The objective of this study was to further develop the Ida Institute model on communication partners' (CPs) journey through experiences of person with hearing impairment (PHI), based on the perspectives of CPs. Nine CPs of hearing aid users participated in this study, recruited through the Swansea hearing impaired support group. Semi-structured interviews were conducted, the data were analysed using qualitative thematic analysis and presented with the use of process mapping approach. Seven main phases were identified in the CP journey which includes: (1) contemplation, (2) awareness, (3) persuasion, (4) validation, (5) rehabilitation, (6) adaptation, and (7) resolution. The Ida Institute model (based on professionals' perspective) was compared with the new template developed (based on CPs' perspectives). The results suggest some commonalities and differences between the views of professionals and CPs. A new phase, adaptation, was identified from CPs reported experiences, which was not identified by professionals in the Ida Institute model. The CP's journey model could be a useful tool during audiological enablement/rehabilitation sessions to promote discussion between the PHI and the CP. In addition, it can be used in the training of hearing healthcare professionals. PMID:23533422

The Role of Romantic Partners, Family and Peer Networks in Dating Couples' Views about Cohabitation  

PubMed Central

Emerging adults are increasingly cohabiting, but few studies have considered the role of social context in the formation of their views of cohabitation. Drawing on 40 semi-structured interviews with dating couples, we explored the role of romantic partners, family, and peers on evaluations of cohabitation. In couples where each member had a differing view about cohabitation, one romantic partner’s desire to not cohabit trumped their partner’s more ambivalent feelings about cohabitation. The influence of family in the formation of cohabitation views was evident through a variety of mechanisms, including parental advice, social modeling, religious values, and economic control. Peers also played a key role, with couples using the vicarious trials of their peer networks to judge how cohabitation would affect their own relationship. By using a couple perspective, assessing reports from both members of each couple, this study showcases how beliefs about cohabitation are formed within an intimate dyad. PMID:23087542

Cooperation with a competition for partners  

Microsoft Academic Search

A finitely repeated prisoner's dilemma game has a unique, defective Nash equilibrium. This paper shows that, in contrast, cooperation can be achieved in a subgame-perfect Nash equilibrium of a finitely repeated prisoner's dilemma game when players can choose their partners. Partner choices of all players produce an endogenous network in which a multi-player prisoner's dilemma is played. Cooperation is shown

Intimate partner violence among stigmatized Latina workers.  

PubMed

Latinas recently immigrated to the United States who work in bars or cantinas are at risk of experiencing intimate partner violence (IPV) due to the heavy drinking and sex-related expectations associated with their work and the stigmatized nature of their occupation. We explored the influence of demographic characteristics, substance abuse, and sexual risk behaviors on IPV reported by cantineras for primary and nonprimary sexual partners. Results based on interviews conducted with 669 cantineras indicate that length of residency in the United States and current sexual practices predict IPV perpetrated by both their primary and nonprimary sexual partners. There were also partner-specific predictors of violence related to the substance use and working practices of cantineras. Our findings have implications for understanding the partner violence experienced by this subgroup of stigmatized Latina immigrants and for the ability of current IPV research to capture their experience.

Teleportation with Multiple Accelerated Partners  

E-print Network

As the current revolution in communication is underway, quantum teleportation can increase the level of security in quantum communication applications. In this paper, we present a quantum teleportation procedure that capable to teleport either accelerated or non-accelerated information through different quantum channels. These quantum chan- nels are based on accelerated multi-qubit states, where each qubit of each of these channels represent a partner. Namely, these states are the the W state, Greenberger-Horne-Zeilinger (GHZ) state, and the GHZ-like state. Here, we show that the fidelity of teleporting acceler- ated information is higher than the fidelity of teleporting non-accelerated information, both through a quantum channel that is based on accelerated state. Also, the comparison among the performance of these three channels shows that the degree of fidelity depends on type of the used channel, type of the measurement, and value of the acceleration. The result of comparison concludes that teleporting information through channel that is based on the GHZ state is more robust than teleporting information through channels that are based on the other two states. For future work, the proposed procedure can be generalized later to achieve communication through a wider quantum network.

Partner Caregiving in Older Cohabiting Couples  

PubMed Central

Objectives. Despite the rapidly increasing prevalence of cohabitation among older adults, the caregiving literature has exclusively focused on formally married individuals. Extending prior work on intra-couple care, this study contrasts frail cohabitors’ patterns of care receipt from a partner to that of frail spouses. Methods. Using nationally representative panel data from the Health and Retirement Study (2000, 2002, 2004, and 2006), we estimate random effects cross-sectional times series models predicting frail cohabitors’ likelihood of receiving partner care compared with their married counterparts’. Conditional on the receipt of intra-couple care, we also examine differences in marital and nonmarital partners’ caregiving hours and caregiving involvement relative to other helpers. Results. Net of sociodemographic, disability, and comorbidity factors, we find that cohabitors are less likely to receive partner care than married individuals. However, caregiving nonmarital partners provide as many hours of care as spouses while providing a substantially larger share of disabled respondents’ care than marital partners. Discussion. Cohabitation and marriage have distinct implications for older adults’ patterns of partner care receipt. This study adds weight to a growing body of research emphasizing the importance of accounting for older adults’ nontraditional union forms and of examining the ramifications of cohabitation for older adults’ well-being.

Situational ambiguity and gendered patterns of arrest for intimate partner violence.  

PubMed

Using data from the 2005 National Incident-Based Reporting System (NIBRS), this analysis focuses on the impacts that domestic violence mandatory arrest policies have on arrest outcomes in "situationally ambiguous" cases: cases where both the female and male partners have been identified by police as both a victim and an offender. Results indicate that although officers arrest male partners more frequently than female partners, after controlling for incident and individual factors, mandatory arrest policies disproportionately affect women. Furthermore, correlates of arrest differ for male-only arrests versus female-only arrests. These findings are discussed in the context of changing legal responses to domestic violence. PMID:22411299

The purpose of this study was to explore variations in demographics, culture, self-esteem and intimate partner violence among Hispanic women according to birthplace, and to identify factors that are associated with these differences in intimate partner violence. Baseline data from a randomized control trial testing the efficacy of an HIV prevention program was used. Path analyses identified differences in intimate partner violence between Colombian women and women from other Central/South American. Self-esteem was the only factor that was associated with these differences. Interventions that address the unique needs of Hispanic women from different subgroups are needed. PMID:23363655

Men's beliefs and attitudes toward intimate partner violence against women in Pakistan.  

PubMed

This article documents the beliefs and attitudes of men toward intimate partner violence in Pakistan. Men's beliefs and attitudes toward partner violence are shaped by the life-long process of gender socialization, where the role of wife is projected as submissive and docile. Drawing on eight in-depth interviews and four focus group discussions (FGDs) conducted in Lahore and Sialkot, this article presents how men perceive and justify partner violence within the context of Pakistani society. The data show that the construct of "ideal wife" inculcated among men fits into Foucault's notion of "docile bodies," which are subjected to control, discipline, and violent punishment.

Intimate partner aggression and women's work outcomes.  

PubMed

Using conservation of resources theory, we examined the relationship between intimate partner aggression enacted against heterosexual women and 3 types of work-related outcomes for these women: withdrawal while at work (i.e., cognitive distraction, work neglect), withdrawal from work (i.e., partial absenteeism, intentions to quit), and performance. In Study 1, we compared withdrawal both at and from work across 3 clinically categorized groups of women (n = 50), showing that experiencing physical aggression is related to higher work neglect. We replicated and extended these findings in Study 2 using a community sample of employed women (n = 249) by considering the incremental variance explained by both physical aggression and psychological aggression on these same outcomes. Results showed that physical aggression predicted higher levels of withdrawal both at and from work, with psychological aggression predicting additional variance in partial absenteeism over and above the effects of physical aggression. Study 3 extended the model to include academic performance as an outcome in a sample of female college students (n = 122) in dating relationships. Controlling for the women's conscientiousness, psychological aggression predicted lower academic performance after accounting for the effects of physical aggression. We discuss theoretical and practical implications of these results, as well as directions for future research. (PsycINFO Database Record (c) 2014 APA, all rights reserved). PMID:25068818

The interpersonal worlds of bullies: parents, peers, and partners.  

PubMed

Research has yet to examine the social influences of parents, peers, and partners on bullying. This study explored the impact of social relationships on bullies, victims, bully/victims, and uninvolved participants. A sample of 370 college-age participants was asked about bullying, family environment, friends' illegal behavior, and conflict resolution tactics in romantic relationships. Results indicated controls came from more secure and engaged families. Bully/victims reported friends engaging in more illegal behaviors than victims and uninvolved participants. Bullies and bully/victims reported more psychological coercion from their romantic partner. A logistic regression revealed peer illegal behaviors, psychological aggression, physical assault, and sexual coercion in romantic relationships best predicted bullies from non-bullies (67.3%). Based on these results, the interpersonal world of those involved with bullying significantly impacts behaviors. PMID:24305866

Male adolescent sexual behavior, the forgotten partner: a review.  

PubMed

It is encouraging that after years of focusing attention on the female's ability and responsibility to manage her reproductive behavior, the male is finally beginning to receive notice and attention. Ironically, before the widespread use of the Pill and the IUD, men and male birth control methods played an important role in family planning. Even today, reliance on vasectomies, the condom and withdrawal account for 25% of the contraceptive use among couples and trend statistics point to an increased interest among selected populations in the use of barrier methods that require partner cooperation for effective use. Yet, most small scale and nationwide knowledge, attitudes and practice (KAP) studies focus on the female, particularly the teen-age female. With the exception of fragmentary survey data, pertinent information about male adolescent sexual activity is virtually nonexistent. The growing consensus among researchers and planners is that it is now crucial to research the forgotten partner--the adolescent male. PMID:6558293

Intimate Partner Violence among West African Immigrants  

PubMed Central

Although the number of African immigrants arriving to the United States has increased significantly, there has been little investigation regarding their experiences of intimate partner violence or coping strategies. This study used focus groups and individual interviews to explore intimate partner violence among 32 heterosexual West African immigrants. Results suggest that although cultural expectations influence their coping strategies, West African–born men and women face different realities, with women reporting multiple instances of abuse and a sense of frustration with the existing options for assistance. Although participants discussed multilevel support structures within the immediate West African community to address intimate partner violence, all of these options maintained a gender hierarchy, leaving women dissatisfied. Challenges and barriers to partner violence resolution and coping strategies are identified. Results are examined in terms of their implications for addressing the needs of this underserved population. Implications for future research and services are discussed and highlighted.

National Laboratories and Internatioanl Partnering  

SciTech Connect

For nearly fifty years the US held a dominant position in research and development in the free world. The situation has changed dramatically in the last decade. Countries around the world realize that to foster sustainable economic growth, they must build and maintain a foundation in science and technology. The time in which a country could base its gross national product solely on extraction of raw materials or on people-intensive manufacturing is drawing to a close. The funding for research and development has been growing in the rest of the world, while US expenditures have not kept pace. In 1961, the United States funded 71 `?40 of the world's R&D. It is estimated that the US contribution to research and development fimding today has reached the 3 3o/0 level, and will drop to 26o/0 of the world's total by 2003.1 In 1981 US government spending per capita on non-defense research and development was nearly fifty percent above our major competitors; by 2002 it is projected to be f@ percent below them.2 This trend has a profound impact on how research and development institutions in the United States plan for their future technical growth. Sandia National Laboratories, as one of the largest US-government tided research establishments, has been watching this trend for some time. %ndi~ focusing on the Laboratories' missions in nuclear weapons and related defense systems, energy security, environmental integrity, and emerging national challenges, is committed to bringing the best in world-class technology to bear on the nation's problems. We realize maintaining our state-of-the-art technolo=~ base requires we look not only to domestic sources in universities, industries and other laboratories, but also to sources overseas. The realization that we must be "worldwide gatherers of technology" has led Sandia National Laboratories to consider the question of international partnering in some detaiI. As a national laboratory with a national security mission we are well aware of the issues that we face in pursuing international collaborations. In order to make the proper decisions, we are interested in understanding the history of such partnerships, when they are appropriate, why we expect them to be important, the risks they present and what we can do to mitigate those risks.

Facebook Surveillance of Former Romantic Partners: Associations with PostBreakup Recovery and Personal Growth  

PubMed Central

Abstract Previous research has found that continuing offline contact with an ex-romantic partner following a breakup may disrupt emotional recovery. The present study examined whether continuing online contact with an ex-partner through remaining Facebook friends and/or engaging in surveillance of the ex-partner's Facebook page inhibited postbreakup adjustment and growth above and beyond offline contact. Analysis of the data provided by 464 participants revealed that Facebook surveillance was associated with greater current distress over the breakup, more negative feelings, sexual desire, and longing for the ex-partner, and lower personal growth. Participants who remained Facebook friends with the ex-partner, relative to those who did not remain Facebook friends, reported less negative feelings, sexual desire, and longing for the former partner, but lower personal growth. All of these results emerged after controlling for offline contact, personality traits, and characteristics of the former relationship and breakup that tend to predict postbreakup adjustment. Overall, these findings suggest that exposure to an ex-partner through Facebook may obstruct the process of healing and moving on from a past relationship. PMID:22946958

Using a partner?s facial emotion to elucidate social dominance motivation induced by an SSRI.  

PubMed

Previous studies independently showed that acute treatment with a selective serotonin reuptake inhibitor (SSRI) enhanced happy face recognition, and dominance behaviors which might reflect enhancement of reward sensitivity. The present study aimed to determine whether such a mechanism would be related to social resource acquisition induced by an SSRI. Forty healthy subjects were recruited for the experiment. A randomized, double-blind, placebo-controlled crossover nested within confederate type (happy, fearful, or sad) trial of a single-dose of 10mg escitalopram versus placebo was conducted with a two-week washout period. In each of the treatment groups, the subjects interacted socially with one of the three types of confederate in a waiting room for 3-minute. Then, they went to an individual laboratory and were led to believe that they played the Mixed-motive game with the confederate. The game measures punitive/cooperative behaviors by how participants allocate higher/lower game scores to the confederate and communicate cooperation/ingratiation/helplessness/sadness/blaming/extrapunitive, messages to the confederate. Significant treatment-by-confederate type interactions were observed through game score distributions and ingratiation messages to the confederate and attentive eye gaze. In the happy confederate condition, escitalopram increased ingratiation messages and lowered points awarded to the confederate. In the fearful confederate condition, escitalopram increased ingratiation messages and reduced time spent looking away from the confederate. No changes in these measures were found in the sad confederate condition. Therefore acute escitalopram treatment enhances reward sensitivity to the facial emotions of social partners which in turn increases social resource acquisition and social dominance towards happy but not fearful social partners.

Genetic Control of Hotspots  

NSDL National Science Digital Library

With the exception of identical twins, individuals have different genetic makeup, which results from two key processes. During meiosis, maternal and paternal homologous chromosomes assort randomly to form daughter cells (gametes), thus generating different combinations of maternal and paternal chromosomes. Additional variation is generated by recombinations or crossovers, in which parts of homologous chromosomes are exchanged, resulting in a new combination of parental alleles. Parvanov et al., Baudat et al., and Myers et al. report the identification of a mammalian geneâÂÂPR domain containing 9 (PRDM9)âÂÂthat controls the extent to which crossovers occur in preferred chromosomal locations, known as "hotspots."

The nature of interfirm partnering in supply chain management  

Microsoft Academic Search

This paper conceptually integrates the antecedents and consequences of strategic and operational partnering. We suggest a continuum exists from strategic to operational partnering depending on the level of antecedents, orientation, and implementation. This paper, thus, expands the theory of partnering by providing an inclusive picture of the “partnering” phenomenon with the environmental pressures, antecedents, orientation, implementation, and consequences of strategic

Perpetration of intimate partner aggression by men and women in the Philippines: prevalence and associated factors.  

PubMed

This study uses data from the 2002 Cebu Longitudinal Health and Nutrition Survey to examine the prevalence of and factors associated with intimate partner violence perpetration by husbands and wives in Cebu, Philippines. Multinomial logistic regression was used to identify the factors associated with wife-only, husband-only, and reciprocal perpetration. About 26% of women reported that either they or their partner perpetrated at least one physically aggressive act during the past year, whereas 22% reported sexual coercion by their husband during their relationship. The most common reason cited for hurting the partner was his or her alcohol use, partner nagging, the wife fighting back, and jealousy. In the regression analysis, the wife's alcohol use and violence between the wife's parents were predictors of all three perpetrator groups. The importance of regular church attendance and husband control and dominance varied for the groups. Research and prevention implications are discussed. PMID:18768743

Trait hostility is associated with systemic inflammation in married couples: an actor-partner analysis.  

PubMed

Trait anger and hostility predict the development of coronary heart disease, and systemic inflammation may partly mediate this association. In a sample of 94 middle-aged and older married couples, we replicate research showing a within individuals (i.e., actor effect) association of trait hostility with high sensitivity C-reactive protein (hsCRP). As a novel extension of that research, the present study also examined the association of individuals' trait hostility with their partners' hsCRP (i.e., partner effect). Controlling for potential confounds, trait hostility, measured with the Buss-Perry Aggression Questionnaire, was significantly associated with both participants' own hsCRP, b=.0528 (SE=.0196), p=.008 and their partners' levels b=.0473 (SE=.0194), p=.016. Hence, the inflammatory correlates of trait hostility occur not only within individuals but between them, as well. The effects of unhealthy personality traits may extend to intimate partners and possibly other social network members. PMID:25019591

Alcohol Misuse and Multiple Sexual Partners  

PubMed Central

Introduction We examine the association between self-reported alcohol misuse and alcohol use within 2 hours of having sex and the number of sexual partners among a sample of African-American and Latino emergency department (ED) patients. Methods Cross-sectional data were collected prospectively from a randomized sample of all ED patients during a 5-week period. In face-to-face interviews, subjects were asked to report their alcohol use and number of sexual partners in the past 12 months. Data were analyzed using multiple variable negative binomial regression models, and effect modification was assessed through inclusion of interaction terms. Results The 395 study participants reported an average of 1.4 (standard error = 0.11) sexual partners in the past 12 months, 23% reported misusing alcohol, and 28% reported consuming alcohol before sex. There was no statistically significant association between alcohol misuse and the number of sexual partners; however, alcohol before sex was associated with a larger number of sexual partners in the past year. Moreover, among those who misused alcohol, participants who reported alcohol before sex were 3 times more likely to report a higher number of sexual partners (risk ratio = 3.2; confidence interval [CI] =1.9–5.6). The association between alcohol use before sex and number of sexual partners is dependent upon whether a person has attributes of harmful drinking over the past 12 months. Overall, alcohol use before sex increases the number of sexual partners, but the magnitude of this effect is significantly increased among alcohol misusers. Conclusion Alcohol misusers and those who reported having more than 1 sexual partner were more likely to cluster in the same group, ie, those who used alcohol before sex. Efforts to reduce the burden of sexually transmitted diseases, including human immunodeficiency virus, and other consequences of risky sexual behavior in the ED population should be cognizant of the interplay of alcohol and risky sexual behaviors. EDs should strive to institute a system for regular screening, brief intervention, and referral of at-risk patients to reduce negative consequences of alcohol misuse, including those of risky sexual behaviors.

Adult violence with the mother and sibling as predictors of partner violence.  

PubMed

The present study provides the first available evaluation of how violence with the mother and siblings during adulthood is associated with the occurrence of partner violence in young adults. Because a pattern of reciprocal partner violence is well documented, the authors hypothesized that reciprocal violence would also be found for adults and their mothers and for adults and their siblings. The authors also hypothesized that reciprocal violence with the mother and sisters would explain variance in partner violence even when controlling for other known predictors (poverty, poor family support, stress, anger, low self-esteem). Study participants included 377 college adults (114 men, 263 women; mean age = 24.4 years) who completed questionnaires to report their present violence to and from their mothers, sisters, brothers, and romantic partners. Violence is measured with a modified Conflict Tactics Scale. No sibling gender differences are found in violence reported as adults. Factor analysis confirms good fit for three clusters of reciprocal violence for adults: violence with the mother, violence with siblings, violence with the romantic partner. Violence with the mother and siblings significantly explains variance in partner violence even after controlling for other contextual variables, but only for women. One interpretation of present results is that because women receive less socialization than men to use violence, these two within-family models of violence have more significance for increasing their risk of partner violence. Partner violence prevention programs could include participation of mothers and siblings to enhance development of more peaceful conflict resolution patterns within and outside the family.

Partners in caring: a partnership for healing.  

PubMed

This article describes one organization's effort to create a family-friendly environment that supports the choice of patients for involvement of a family member or loved one in their care. Changing a culture requires a process that can emotionally drive the caregivers to agree with the need to change and sustain the efforts over a long period. This project, Partners in Caring, describes the philosophy, the journey of changing a culture, and the results achieved over a 7-year period. The Partners in Caring philosophy is "a commitment between a patient, care partner and healthcare team to a relationship of hands-on support based on compassion, communication and choice empowering people to heal in a nurturing manner." This concept laid a foundation for the development of a new model of care, which is described. The implementation has resulted in an improved patient and staff satisfaction and a decrease in patient complaints. PMID:16648722

Evaluating self and partner physical attractiveness.  

PubMed

This study used a novel questionnaire to examine ratings of self and partner physical attractiveness. Seventy-two men and 83 women estimated their own and their opposite-sex partner's overall physical attractiveness and the attractiveness of various body parts and measures. They also answered six simple questions concerning physical attractiveness. Results showed significant gender differences in self-estimates of overall facial attractiveness and upper body features. In general, and regardless of gender, participants rated their opposite-sex partners as being significantly more attractive than themselves. In addition, the results showed that body weight and facial attractiveness were the best predictors of overall physical attractiveness. Implications of these results in terms of social biases are considered. PMID:18089256

Interactions between perceptions of relationship quality and postnatal depressive symptoms in Australian, primiparous women and their partners.  

PubMed

The present study aimed to investigate interactions between perceptions of quality of intimate partner relationship and postnatal depressive symptoms in members of heterosexual couples 6 months after the birth of their first infant, while controlling for other relevant risk and protective factors. Secondary analysis was conducted on data from a prospective community cohort study of Australian, primiparous women and their partners. The outcome measure was Edinburgh Postnatal Depression Scale score. Quality of intimate partner relationship, personality factors and infant behaviour were assessed using the standardised Intimate Bonds Measure, Vulnerable Personality Style Questionnaire and Barr Chart respectively. Complete data were available for 161 couples. Associations between Edinburgh Postnatal Depression Scale scores and own and partner ratings of the intimate partner relationship were estimated simultaneously using multilevel modelling. When other relevant factors were controlled, relationships in which partners were perceived as critical, coercive or intimidating were associated with significantly more depressive symptoms in individuals (P=0.004) as well as their partners (P=0.008). In both women and men, vulnerable personality traits, coincidental adverse life events and more infant crying and fussing were also associated with significantly more depressive symptoms. Thus, the quality of the intimate partner relationship is significantly associated with postnatal mental health in both women and men, especially in the context of coincidental stressful events including infant crying.

Intimate partner violence within law enforcement families.  

PubMed

Using data from the Baltimore Police Stress and Domestic Violence study, the authors examined how exposure to stressful events on the job affects law enforcement employees' physical aggression toward domestic partners, evaluating the role of negative emotions and authoritarian spillover in mediating the impact of such task-related stress. The authors consulted general strain theory and angry aggression theory to explain domestic violence in police families. Significant positive effects on physical aggression toward an intimate partner were found for variables measuring authoritarian spillover and negative emotions. However, these effects were different for different gender and racial groups. PMID:20587471

Partner notification: preferences of Melbourne clients and the estimated proportion of sexual partners they can contact.  

PubMed

This study was conducted to determine the estimated proportion of contactable sexual partners, the most common types of contact information available and the most acceptable contact tracing strategies for our clients. Five hundred 'walk in' clients completed a questionnaire about their total number of sexual partners, the proportion of contactable partners and available contact information. Women had the highest estimated number of contactable partners (89-94%), men who have sex with men had the lowest (51-73%). The preferred contact tracing strategy was to give partners a website address (76%) and the least preferred was provider referral (33%). There was a difference in the type of information available for contacting sexual partners (P <0.001); most commonly clients reported partners contactable by phone or face to face and least commonly through a third person. The currently used method (doctor's letter) is not the preferred choice of these clients and more innovative methods using recent technology may prove more effective. PMID:15186588

Assessing information and decision preferences of men with prostate cancer and their partners.  

PubMed

The purpose of this study was to identify and compare information and decision preferences of men with prostate cancer and their partners at the time of diagnosis. A convenience sample of 80 couples was recruited from The Prostate Centre in Vancouver, Canada. Participants used a computerized version of two previously used measures with this population: Control Preferences Scale and Information Survey Questionnaire. Results showed that men had a preference to play either an active or a collaborative role in decision making with their physician (92.5%) and partners (100%). The majority (55%) of partners wanted to play a collaborative role in treatment decision making. Couples identified prognosis, stage of disease, treatment options, and side effects as the top 4 information preferences. Men ranked information on sexuality more important than partners, and partners ranked information on home self-care higher than men. Men who had sons, a positive family history, and lower levels of education ranked heredity risk significantly higher. Profiles of information categories did not differ according to role preferences of either men or partners. The computer program has been shown to be a reliable and acceptable method of assessing information and decision preferences of these couples. An individualized approach is suggested, given the high reliability of individual's profiles. PMID:11838719

Status compatibility and help-seeking behaviors among female intimate partner violence victims.  

PubMed

Given the far-reaching social, personal, and economic costs of crime and violence, as well as the lasting health effects, understanding how women respond to domestic violence and the types of help sought are critical in addressing intimate partner violence. We use a nationally representative dataset (Canadian General Social Survey, Personal Risk, 1999) to examine the help-seeking behaviors of female intimate partner violence victims (N = 250). Although victims of violent crime often do not call the police, many victims, particularly women who have been battered by their partner rely on family, friends, social service, and mental health interventions in dealing with the consequences of violent crime. We examine the role of income, education, and employment status in shaping women's decisions to seek help, and we treat these economic variables as symbolic and relative statuses as compared to male partners. Although family violence researchers have conceptualized the association between economic variables and the dynamics of intimate partner violence with respect to the structural dimensions of sociodemographic factors, feminist researchers connect economic power to family dynamics. Drawing on these literatures, we tap the power in marital and cohabiting relationships, rather than treating these variables as simply socioeconomic resources. Controlling for other relevant variables we estimate a series of multivariate models to examine the relationship between status compatibilities and help-seeking from both formal and informal sources. We find that status incompatibilities between partners that favor women increase the likelihood of seeking support in dealing with the impact of violence. PMID:22946106

Sexual communication between early adolescents and their dating partners, parents, and best friends.  

PubMed

This study assessed early adolescents' sexual communication with dating partners, parents, and best friends about six sexual health topics: condoms, birth control, sexually transmitted diseases (STDs), human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), pregnancy, and abstinence/waiting. Using a school-based sample of 603 youth (ages 12 to 15; 57% female; 46% Caucasian), we examined communication differences across demographic and developmental factors, tested whether communication with parents and best friends was associated with greater communication with partners, and examined associations between communication and condom use. More than half of participants had not discussed any sexual topics with their dating partners (54%), and many had not communicated with parents (29%) or best friends (25%). On average, communication was more frequent among adolescents who were female, African American, older, and sexually active, despite some variation in subgroups across partner, parent, and friend communication. Importantly, communication with parents and friends--and the interaction between parent and friend communication--was associated with increased communication with dating partners. Further, among sexually active youth, increased sexual communication with partners was associated with more frequent condom use. Results highlight the importance of understanding the broader family and peer context surrounding adolescent sexual decision making and suggest a possible need to tailor sexual communication interventions.

Disclosure of microbicide gel use to sexual partners: influence on adherence in the CAPRISA 004 trial.  

PubMed

Young women in sub-Saharan Africa are disproportionately affected by HIV, making the development of women initiated and controlled methods of prevention, including microbicides, a priority. Adherence is pivotal to microbicide efficacy and partner related factors are known to impact adherence. An analysis of disclosure of gel use to sexual partners and adherence in CAPRISA 004 women was conducted to better understand this relationship. Partner disclosure was significantly associated with a modest 4.2 % increased adherence (71.0 vs. 66.8 %, p = 0.03). Most women rated the experience of disclosure as positive, despite 6.7 % of partners expressing a negative reaction.Participants who disclosed were more likely to reside with their regular partner (14.4 vs. 8.4 %; p = 0.01) and reported consistent condom use at baseline (32.9 vs. 20.9 %; p < 0.01). Partner disclosure needs to be better understood as a potential facilitator or barrier to microbicide adherence. PMID:24633715

Strategy Guideline: Partnering for High Performance Homes  

SciTech Connect

High performance houses require a high degree of coordination and have significant interdependencies between various systems in order to perform properly, meet customer expectations, and minimize risks for the builder. Responsibility for the key performance attributes is shared across the project team and can be well coordinated through advanced partnering strategies. For high performance homes, traditional partnerships need to be matured to the next level and be expanded to all members of the project team including trades, suppliers, manufacturers, HERS raters, designers, architects, and building officials as appropriate. In an environment where the builder is the only source of communication between trades and consultants and where relationships are, in general, adversarial as opposed to cooperative, the chances of any one building system to fail are greater. Furthermore, it is much harder for the builder to identify and capitalize on synergistic opportunities. Partnering can help bridge the cross-functional aspects of the systems approach and achieve performance-based criteria. Critical success factors for partnering include support from top management, mutual trust, effective and open communication, effective coordination around common goals, team building, appropriate use of an outside facilitator, a partnering charter progress toward common goals, an effective problem-solving process, long-term commitment, continuous improvement, and a positive experience for all involved.

Understanding Adolescent and Family Influences on Intimate Partner Psychological Violence During Emerging Adulthood and Adulthood  

PubMed Central

The intergenerational transmission of violence directed toward intimate partners has been documented for the past three decades. Overall, the literature shows that violence in the family of origin leads to violence in the family of destination. However, this predominately cross–sectional or retrospective literature is limited by self–selection, endogeneity, and reporter biases as it has not been able to assess how individual and family behaviors simultaneously experienced during adolescence influence intimate partner violence throughout adulthood. The present study used data from the Iowa Youth and Families Project (IYFP; N = 392; 52 % Female), a multi–method, multi–trait prospective approach, to overcome this limitation. We focused on psychological intimate partner violence in both emerging adulthood (19 – 23 years) and adulthood (27 – 31 years), and include self and partner ratings of violence as well as observational data in a sample of rural non-Hispanic white families. Controlling for a host of individual risk factors as well as interparental psychological violence from adolescence (14 – 15 years), the results show that exposure to parent–to–child psychological violence during adolescence is a key predictor of intimate partner violence throughout adulthood. In addition, negative emotionality and the number of sexual partners in adolescence predicted intimate partner violence in both emerging adulthood and adulthood. Exposure to family stress was associated positively with intimate partner violence in adulthood but not in emerging adulthood, whereas academic difficulties were found to increase violence in emerging adulthood only. Unlike previous research, results did not support a direct effect of interparental psychological violence on psychological violence in the next generation. Gender differences were found only in emerging adulthood. Implications of these findings are discussed in light of the current literature and future directions. PMID:23430562

Effects of an HIV peer prevention intervention on sexual and injecting risk behaviors among injecting drug users and their risk partners in Thai Nguyen, Vietnam: A randomized controlled trial  

PubMed Central

Globally, 30% of new HIV infections outside sub-Saharan Africa involve injecting drug users (IDU) and in many countries, including Vietnam, HIV epidemics are concentrated among IDU. We conducted a randomized controlled trial in Thai Nguyen, Vietnam, to evaluate whether a peer oriented behavioral intervention could reduce injecting and sexual HIV risk behaviors among IDU and their network members. 419 HIV-negative index IDU aged 18 years or older and 516 injecting and sexual network members were enrolled. Each index participant was randomly assigned to receive a series of six small group peer educator-training sessions and three booster sessions in addition to HIV testing and counseling (HTC) (intervention; n = 210) or HTC only (control; n = 209). Follow-up, including HTC, was conducted at 3, 6, 9 and 12 months post-intervention. The proportion of unprotected sex dropped significantly from 49% to 27% (SE (difference) = 3%, p < 0.01) between baseline and the 3-month visit among all index-network member pairs. However, at 12 months, post-intervention, intervention participants had a 14% greater decline in unprotected sex relative to control participants (Wald test = 10.8, df = 4, p = 0.03). This intervention effect is explained by trial participants assigned to the control arm who missed at least one standardized HTC session during follow-up and subsequently reported increased unprotected sex. The proportion of observed needle/syringe sharing dropped significantly between baseline and the 3-month visit (14% vs. 3%, SE (difference) = 2%, p < 0.01) and persisted until 12 months, but there was no difference across trial arms (Wald test = 3.74, df = 3, p = 0.44).

Ants use partner specific odors to learn to recognize a mutualistic partner.  

PubMed

Regulation via interspecific communication is an important for the maintenance of many mutualisms. However, mechanisms underlying the evolution of partner communication are poorly understood for many mutualisms. Here we show, in an ant-lycaenid butterfly mutualism, that attendant ants selectively learn to recognize and interact cooperatively with a partner. Workers of the ant Pristomyrmex punctatus learn to associate cuticular hydrocarbons of mutualistic Narathura japonica caterpillars with food rewards and, as a result, are more likely to tend the caterpillars. However, the workers do not learn to associate the cuticular hydrocarbons of caterpillars of a non-ant-associated lycaenid, Lycaena phlaeas, with artificial food rewards. Chemical analysis revealed cuticular hydrocarbon profiles of the mutualistic caterpillars were complex compared with those of non-ant-associated caterpillars. Our results suggest that partner-recognition based on partner-specific chemical signals and cognitive abilities of workers are important mechanisms underlying the evolution and maintenance of mutualism with ants.

Rules about casual sex partners, relationship satisfaction, and HIV risk in partnered gay and bisexual men.  

PubMed

The authors used latent class analysis to investigate rules guiding nonmonogamy in partnered gay and bisexual men. Data are from a 2010 survey (N = 463) from which those in relationships (n = 191) were analyzed. More than half (56%) were nonmonogamous, and these men responded to 13 rules about sex outside of their relationship. The safe anonymous sex group (34%) included men who indicated that they must use condoms for anal sex and not have sex with people they know. The communication mandate group (19%) included men who indicated that they must talk about outside partners before sex occurs, disclose their relationship status to outside partners, and use condoms for anal sex. The play together group (9%) included men who indicated that they must play with others as a couple, not have anal sex with outside partners, and not spend the night with outside partners. Those in the no salient rule group (37%) were individuals who did not endorse a clear set of rules. These 4 groups (and compared with monogamous men) differed in age, agreement formality and flexibility, relationship satisfaction, and whether anal sex recently occurred with casual partners. This study provides a novel approach for understanding nonmonogamous same-sex relationships and highlights their complexity. PMID:23768194

Empowerment, partner's behaviours and intimate partner physical violence among married women in Uganda  

PubMed Central

Background There is dearth of knowledge and research about the role of empowerment, partners’ behaviours and intimate partner physical violence (IPPV) among married women in Uganda. This paper examined the influence of women’s empowerment and partners’ behaviours on IPPV among married women in Uganda. Methods The 2011 Uganda Demographic and Health Survey data were used, selecting a weighted sample of 1,307 women in union considered for the domestic violence module. Cross tabulations (chi-square tests) and multivariate logistic regressions were used to identify factors associated with IPPV. Results The prevalence of IPPV among women in union in Uganda is still high (41%). Women’s occupation was the only measure of empowerment that was significantly associated with IPPV, where women in professional employment were less likely to experience IPPV. Women from wealthy households were less likely to experience IPPV. IPPV was more likely to be reported by women who had ever had children and witnessed parental IPPV. IPPV was also more likely to be reported by women whose husbands or partners: accused them of unfaithfulness, did not permit them to meet female friends, insisted on knowing their whereabouts and sometimes or often got drunk. Women who were afraid their partners were also more likely to report IPPV. Conclusion In the Ugandan context, women’s empowerment as assessed by the UDHS has limited mitigating effect on IPPV in the face of partners’ negative behaviours and history of witnessing parental violence.

PIKfyve: PARTNERS, SIGNIFICANCE, DEBATES AND PARADOXES  

PubMed Central

Key components of membrane trafficking and signaling machinery in eukaryotic cells are proteins that bind or synthesize phosphoinositides. PIKfyve, a product of an evolutionarily conserved single-copy gene has both these features. It binds to membrane phosphatidylinositol (PtdIns)3P and synthesizes PtdIns(3,5)P2 and PtdIns5P. Molecular functions of PIKfyve are elusive but recent advances are consistent with a key role in the course of endosomal transport. PIKfyve dysfunction induces endosome enlargement and profound cytoplasmic vacuolation, likely as a result of impaired normal endosome processing and membrane exit out of endosomes. Multicellular organisms with genetically impaired function of PIKfyve or that of the PIKfyve protein partners regulating PtdIns(3,5)P2 homeostasis display severe disorders, including embryonic/perinatal death. This review describes recent advances on PIKfyve functionality in higher eukaryotes, with particular reference to biochemical and genetic insights in PIKfyve protein partners. PMID:18304842

Geographic concentration of violence between intimate partners.  

PubMed Central

OBJECTIVES: To explore geographic patterns of violence between intimate partners in a metropolitan area with one of the highest injury mortality rates in the nation-Duval County, Florida, which includes the city of Jacksonville. METHODS: Using police reports of all serious violent incidents in Duval County in 1992 excluding robberies, the authors analyzed patterns in the location of the incidents. Only cases for which the relationship between the offender and victim was recorded were used. RESULTS: Thematic maps reveal that census tracts with rates above the 75th percentile of assaultive violence between intimates are clustered in certain parts of the city. Concentrated poverty tracts had median rates of violence between intimate nine times higher than other tracts. CONCLUSIONS: The finding that violence between intimate partners is concentrated in central city poverty neighborhoods opens up avenues for prevention. PMID:9071275

The Effects of Acute Alcohol Intoxication, Partner Risk Level, and General Intention to Have Unprotected Sex on Women's Sexual Decision Making with a New Partner  

PubMed Central

Women account for a quarter of all new HIV/AIDS cases, with approximately 65% having contracted the infection via heterosexual contact (CDC, 2008). Few experimental studies have examined interactions among background, partner, and situational characteristics in predicting women’s sexual decisions. The Cognitive Mediation Model provides a useful theoretical framework for assessing likelihood of unprotected sex (Norris, Masters, & Zawacki, 2004). Female social drinkers (n = 230) who had answered questions related to their general intention to have unprotected sex were randomly assigned to an experimental condition based on partner risk level (unknown, low, high) and beverage (control, placebo, low dose, high dose). Participants projected themselves into a story depicting a sexual situation with a man and answered questions about their cognitive appraisals, assertive condom request, and likelihood of unprotected sex. Alcohol effects on appraisal of sexual potential differed by partner risk condition. In the unknown and low risk conditions, placebo and alcohol participants appraised the situation as having greater sexual potential than controls whereas in the high risk condition, only those who consumed alcohol did so. Sexual potential appraisals in turn predicted impelling cognitions about having sex, which in turn predicted assertive condom request and unprotected sex intentions. General intention for unprotected sex independently predicted cognitive appraisals and outcomes. These findings highlight the need for prevention programs that focus on teaching women how to pay attention and consider sexual risk cues presented by potential partners, particularly when under the influence of alcohol.

An evolutionary perspective anticipates predictable forms of sexual conflict in human mating relationships. Humans have evolved a psychology of tactical deployment designed to influence a partner's behavior to be closer to the actor's own optimum. Tactics are diverse, ranging from benefit-bestowing to cost-inflicting. We discuss adaptive problems toward which cost-inflicting violent tactics are utilized: mate poachers, sexual infidelity, mate pregnancy

The impact of maternal age on clinical pregnancy and spontaneous abortion in women undergoing in vitro fertilization and gamete intra-fallopian transfer.  

PubMed

The age at which women should be advised against proceeding with initial or further infertility treatment is one of the many unresolved questions in this area of women's health and was the subject of investigation in this study. One of the major difficulties in determining the impact of maternal age on outcomes is the practice of researchers (publishing in journals) and infertility practitioners (reporting to national registers) of coding age as a categorical rather than a continuous variable. In this study, groups of younger (< 30 years) and older (> 35 years) women undergoing assisted reproduction treatments were compared with regards to clinical pregnancy and spontaneous abortion rates following in vitro fertilization (IVF) or gamete intra-Fallopian transfer (GIFT). Response to different ovarian stimulation protocols was also assessed for the 2 groups. The significance of the relationship between maternal age, clinical pregnancy rates, spontaneous abortion rates and the type of treatment and stimulation protocol employed, was tested using a series of binomial distributions. The results indicated that maternal age adversely affects both clinical pregnancy rates and rates of spontaneous abortion, when summed across treatments and stimulation protocols. However, while the age/outcome relationship held for IVF, the GIFT by age relationship was not significant. Stimulation protocols using clomiphene citrate (CC) or gonadotrophin agonists (GnRHa) may impact negatively on older women.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7848237

Conversion of partially reprogrammed cells to fully pluripotent stem cells is associated with further activation of stem cell maintenance- and gamete generation-related genes.  

PubMed

Somatic cells are reprogrammed to induced pluripotent stem cells (iPSCs) by overexpression of a combination of defined transcription factors. We generated iPSCs from mouse embryonic fibroblasts (with Oct4-GFP reporter) by transfection of pCX-OSK-2A (Oct4, Sox2, and Klf4) and pCX-cMyc vectors. We could generate partially reprogrammed cells (XiPS-7), which maintained more than 20 passages in a partially reprogrammed state; the cells expressed Nanog but were Oct4-GFP negative. When the cells were transferred to serum-free medium (with serum replacement and basic fibroblast growth factor), the XiPS-7 cells converted to Oct4-GFP-positive iPSCs (XiPS-7c, fully reprogrammed cells) with ESC-like properties. During the conversion of XiPS-7 to XiPS-7c, we found several clusters of slowly reprogrammed genes, which were activated at later stages of reprogramming. Our results suggest that partial reprogrammed cells can be induced to full reprogramming status by serum-free medium, in which stem cell maintenance- and gamete generation-related genes were upregulated. These long-term expandable partially reprogrammed cells can be used to verify the mechanism of reprogramming. PMID:24892478

Surviving men's depression: women partners' perspectives.  

PubMed

While men's gendered experiences of depression have been described, the perspectives of women partners who are affected by men's depression have received little attention. Women partners were recruited to explore how men's depression impacts them and its influence on gender regimes. Individual interviews with 29 women spouses were coded and analysed. Although idealized femininity positions women as endlessly patient and caring, our findings reveal significant challenges in attempting to fulfil these gender ideals in the context of living with a male partner who is experiencing depression. The strain and drain of living with a depressed man was a key element of women's experiences. Four sub-themes were identified: (1) resisting the emotional caregiver role, (2) shouldering family responsibilities, (3) connecting men to professional care and (4) preserving the feminine self. The findings suggest that men's depression has great potential to dislocate heterosexual gender regimes, and attention to gender relations should be included to ensure successful care management of men who experience depression.

Factors affecting prevalence and extent of intimate partner violence in Ukraine: evidence from a nationally representative survey.  

PubMed

This study examined the prevalence and ecological correlates of intimate partner violence against women in Ukraine. A nationally representative sample of ever-married female respondents of the 2007 Ukraine Demographic Health Survey was used for this analysis. Findings suggest that although numerous ecological factors predict women's experiences of emotional, physical, and sexual intimate partner violence, two factors were common correlates of all three forms of violence: the frequent intoxication of women's partners and the exhibition of marital controlling behaviors by male perpetrators. Implications for the development of effective programming to prevent violence against Ukrainian women are provided. PMID:23081876

Sexual adjustment after spinal cord injury-comparison of partner experiences in pre- and postinjury relationships.  

PubMed

This study compared the emotional and sexual aspects of relationships before and after spinal cord injury, from the partner's point of view. In addition, the personality characteristics of the partners were investigated. Twenty-six relationships were established before the injury and 23 after. The couples in preinjury relationships had been married or cohabiting for 3.5-51 years (median 24 years), while postinjury relationships ranged from 1 to 8 years (median 2 years). There were substantial differences in age between preinjury and postinjury partners, 21-79 years (median 51 years) and 18-45 years (median 28 years), respectively. Data collection included an 80-item questionnaire, designed to determine different aspects of sexuality, a visual analogue scale Quality of Life (VAS QL) measure and an established inventory of personality characteristics, the Karolinska Scales of Personality (KSP). Eighty-eight per cent of the partners in preinjury and 86% in postinjury relationships considered their overall relationship to be satisfactory. Concerning the sexual aspects of the relationships, several differences were revealed, all favouring postinjury relationships. Some of these held true even when age was treated as a significant factor and statistically controlled. Although the frequency of sexual activity and the variety of sexual expressions used were lower in the preinjury relationships, and perceived deterioration of sex life due to the injury was higher among preinjury partners, there was no significant difference between the two groups in satisfaction with current sex life. Thus, age seems to be a more important factor for sexual adjustment after a spinal cord injury, rather than whether the relationship is established before or after injury. The partners' personality characteristics differed only slightly from those of a sex and age matched reference group and not at all between partners in pre- and postinjury relationships.

Identification of protein binding partners of ALK-5 kinase inhibitors.  

PubMed

We have investigated the binding characteristics of a potent member of the bis-ortho-substituted five-membered nitrogen heterocycle class of ALK-5 kinase inhibitors with lysates of cultured HEK-293 cells to identify protein binding partners of potential biological significance. An affinity chromatographic resin containing an immobilized ALK-5 kinase inhibitor, 2-phenyl-4-[3-(pyridin-2-yl)-1H-pyrazol-4-yl]pyridine, was used to capture specific proteins from the cell lysate. The soluble inhibitor was then used to specifically elute the proteins which selectively bound to the pharmacophore ligand structure. Application of 2-D SDS-PAGE analysis with positive and negative controls demonstrated the inhibitor bound several different proteins via selective molecular recognition processes. The structural features of the specifically eluted proteins were identified by peptide mass fingerprinting (PMF) methods and included proteins with structural, metabolic and chaperone functions. Furthermore, these PMF results identified the therapeutic target in various cancer treatment studies, HSP-70, as a potential high-affinity binding partner. These observations warrant examination of bis-ortho-substituted five-membered nitrogen heterocycles as dual ALK-5/HSP-70 inhibitors for anti-cancer drug development. PMID:24055074

Intimate partner violence: IPV in the LGBT community.  

PubMed

Nationally, the rates of intimate partner violence (IPV) among lesbian, gay, bisexual, or transgender (LGBT) individuals are similar to or greater than rates for heterosexuals. Many have experienced psychological and physical abuse as sexual minorities, making it difficult for them to seek help for IPV. Physician behavior, such as not assuming that all patients are heterosexual, being nonjudgmental, and using inclusive language, can empower LGBT patients to disclose IPV. Also, physicians should ascertain the degree to which the patient is out. The threat of being outed can be an aspect of the power and control exerted by an abusive partner and a significant barrier to seeking help. Physicians should screen for IPV and intervene in a similar manner with LGBT and non-LGBT patients, but they should be aware of potential limitations in resources for LGBT patients, such as shelters. As sexual minorities experiencing IPV, LGBT individuals are at greater risk of depression and substance abuse than are non-LGBT individuals. Minority stress, resulting from stigmatization and discrimination, can be exacerbated by IPV. Physicians should learn about legal issues for LGBT individuals and the availability of community or advocacy programs for LGBT perpetrators or victims of IPV. PMID:24053263

The outreach-assisted model of partner notification with IDUs.  

PubMed Central

OBJECTIVE: This analysis describes the Outreach-Assisted Model of Partner Notification, an innovative strategy for encouraging seropositive injecting drug users (IDUs) to inform their partners of shared human immunodeficiency virus (HIV) exposure. The analysis focuses on two core components of the notification process: the identification of at-risk partners and preferences for self-tell vs. outreach assistance in informing partners of possible exposure to the virus. METHODS: Using community outreach techniques, 386 IDUs were recruited for HIV pretest counseling, testing, and partner notification over a 12-month period. Of these, 63 tested HIV seropositive, and all but three returned for their test results. The 60 who were informed of their serostatus were randomly assigned to either a minimal or an enhanced intervention condition. Participants assigned to the minimal (self-tell) group were strongly encouraged to inform their partners of possible exposure. Those assigned to the enhanced (outreach-assisted) group had the option of either informing one or more of their partner(s) themselves or choosing to have the project's outreach team do so. RESULTS: Together, the 60 index persons who received their results provided names or at least one piece of locating information for a total of 142 partners with whom they perceived having shared possible exposure to the virus within the past five years. By itself, drug use accounted for half of all partners named. Sexual behavior alone accounted for 25% of named partners. Eighty-two percent of the enhanced group preferred to have the outreach team tell at least one partner; the team was requested to notify 71% of the total number of partners whom this group named. CONCLUSIONS: Findings suggest that IDUs want to notify their partners of shared HIV exposure. Outreach assistance was the preferred mode in the majority of cases. Expanding traditional community-based HIV outreach activities to include delivering street-based counseling, test, a partner notification appears to be a positive and workable prevention strategy.

Synchronising movements with the sounds of a virtual partner enhances partner likeability.  

PubMed

Previous studies have demonstrated that synchronising movements with other people can influence affiliative behaviour towards them. While research has focused on synchronisation with visually observed movement, synchronisation with a partner who is heard may have similar effects. We replicate findings showing that synchronisation can influence ratings of likeability of a partner, but demonstrate that this is possible with virtual interaction, involving a video of a partner. Participants performed instructed synchrony in time to sounds instead of the observable actions of another person. Results show significantly higher ratings of likeability of a partner after moving at the same time as sounds attributed to that partner, compared with moving in between sounds. Objectively quantified synchrony also correlated with ratings of likeability. Belief that sounds were made by another person was manipulated in Experiment 2, and results demonstrate that when sounds are attributed to a computer, ratings of likeability are not affected by moving in or out of time. These findings demonstrate that interaction with sound can be experienced as social interaction in the absence of genuine interpersonal contact, which may help explain why people enjoy engaging with recorded music.

Dyadic, Partner, and Social Network Influences on Intimate Partner Violence among Male-Male Couples  

PubMed Central

Introduction: Despite a recent focus on intimate partner violence (IPV) among men who have sex with men (MSM), the male-male couple is largely absent from the IPV literature. Specifically, research on dyadic factors shaping IPV in male-male couples is lacking. Methods: We took a subsample of 403 gay/bisexual men with main partners from a 2011 survey of approximately 1,000 gay and bisexual men from Atlanta. Logistic regression models of recent (<12 month) experience and perpetration of physical and sexual IPV examined dyadic factors, including racial differences, age differences, and social network characteristics of couples as key covariates shaping the reporting of IPV. Results: Findings indicate that men were more likely to report perpetration of physical violence if they were a different race to their main partner, whereas main partner age was associated with decreased reporting of physical violence. Having social networks that contained more gay friends was associated with significant reductions in the reporting of IPV, whereas having social networks comprised of sex partners or closeted gay friends was associated with increased reporting of IPV victimization and perpetration. Conclusion: The results point to several unique factors shaping the reporting of IPV within male-male couples and highlight the need for intervention efforts and prevention programs that focus on male couples, a group largely absent from both research and prevention efforts.

The Role of Reinfection and Partner Notification in the Efficacy of Chlamydia Screening Programs  

PubMed Central

Repeated Chlamydia trachomatis infections after treatment are common. One reason is reinfection from untreated partners in ongoing sexual partnerships. Mathematical models that are used to predict the impact of screening on reducing chlamydia prevalence often do not incorporate reinfection and might overestimate the expected impact. We describe a pair compartmental model that explicitly incorporates sexual partnership duration and reinfection. The pair model predicts a weaker impact of screening when compared directly with a model that does not accommodate partnerships. Effective management of sex partners to prevent reinfection might need to be strengthened in chlamydia control programs. PMID:21186257

Partner switching can favour cooperation in a biological market.  

PubMed

Intraspecific cooperation and interspecific mutualisms can be promoted by mechanisms that reduce the frequency with which cooperative organisms are exploited by unhelpful partners. One such mechanism consists of changing partners after interacting with an uncooperative individual. I used McNamara et al.'s (Nature, 451, 2008, 189) partner switching model as a framework to examine whether this mechanism can select for increased cooperative investment by house sparrows (Passer domesticus) collaborating to rear offspring; previous research on this species has shown that substantial cooperative investments by both pair members are required to achieve high pay-offs from collaborating. I found that the poorer the outcome of a breeding attempt relative to the number of eggs the female invested, the greater the likelihood of partner switching. The incidence of partner switching changed seasonally, with peak switching coinciding with an increase in the number of alternative partners available to females. After females switched pa
