Abstract
OBJECTIVE The purpose of this study was to compare maternal and neonatal outcomes in nulliparous women with nonmedically indicated inductions at term vs those expectantly treated. STUDY DESIGN Data were obtained from maternal and neonatal charts for all deliveries on randomly selected days across 25 US hospitals over a 3-year period. A low-risk subset of nulliparous women with vertex nonanomalous singleton gestations who delivered 38 0/7 to 41 6/7 weeks were selected. Maternal and neonatal outcomes for nonmedically indicated induction within each week were compared with women who did not undergo nonmedically indicated induction during that week. Multivariable analysis was used to adjust for hospital, maternal age, race/ethnicity, body mass index, cigarette use, and insurance status. RESULTS We found 31,169 women who met our criteria. Neonatal complications were either less frequent with nonmedically indicated induction or no different between groups. Nonmedically indicated induction was associated with less frequent peripartum infections (odds ratio [OR], 0.39; 95% confidence interval [CI], 0.16-0.98) at 38 weeks of gestation and less frequent third- and fourth-degree lacerations (OR, 0.60; 95% CI, 0.42-0.86) and less frequent peripartum infections (OR, 0.66; 95% CI, 0.49-0.90) at 39 weeks of gestation. Nonmedically indicated induction was associated with a longer admission-to-delivery time by approximately 3-4 hours and increased odds of cesarean delivery at 38 (OR, 1.50; 95% CI, 1.08-2.08) and 40 weeks (OR, 1.30; 95% CI, 1.15-1.46) of gestation. CONCLUSION At 39 weeks of gestation, nonmedically indicated induction is associated with lower maternal and neonatal morbidity than women who are expectantly treated.

Abstract
In hexagonal crystals such as quartz, an asymmetric Bragg reflection from two equivalent internal crystal planes can separate unpolarized x-rays into two linearly polarized components. The perfectly polarized and tunable x-rays from a synchrotron are ideal to evaluate polarization spitting in detail. One unanticipated feature is that additional reflections from the crystal affect the diffraction intensity of the two polarized components, an effect that is unlikely to matter in polarization spectroscopy of radiating plasmas for which the crystal is intended.

Abstract
BACKGROUND The Defence Medical Services (DMS) primarily recruits its trained General Practitioners (GPs) from the NHS and since 1970, the number of men entering medicine has doubled whereas the number of women has increased 10-fold; female GPs will outnumber their male counterparts by 2017. This study performs a quantitative assessment of the potential impact of feminisation of UK General Practice upon the DMS recruitment and workforce planning. METHODS General Medial Council General Practice Certificate of Completion of Training (GMC GP CCT) data were analysed to identify any change in the percentage of male and female GP Specialty Training Registrars successfully completing GP vocational training between 2007 and 2012, thus becoming potentially recruitable into the DMS as independent GPs. RESULTS A 3% increase was seen in the number of women achieving GMC GP CCT between 2007 and 2012 (p=0.015). The percentage of DMS GP Specialty Training Registrars (GPStRs) gaining their GMC GP CCT in 2012 who were women (25%) was about half that seen nationally (59%). A lack of 2007 by-sex GMC GP CCT data for DMS GPStRs prevented a comparison with 2012. CONCLUSIONS The national increase of only 3% infers feminisation of UK General Practice is not an immediate challenge for the DMS. Nevertheless, as feminisation of the UK GP workforce is expected to continue, the future cohort from whom the DMS will recruit its GPs is likely to contain increasing numbers of women. With the return to contingency, the DMS may wish to consider the implications of increasing numbers of female GPs upon service delivery in the UK and overseas, and explore more flexible medical employment models.

Abstract
In order to establish a successful infection, it is of crucial importance for invading viruses to alter the activities of the regulatory protein p53. Beta-herpesviruses stabilize p53 and likely direct its activities towards generation of a replication-friendly environment. We here study the mechanisms behind HHV-6B-induced stabilization and inactivation of p53. Stable transgene expression of the HHV-6B protein U19 was sufficient to achieve upregulation of p53. U19 bound directly to the p53-regulating protein HDM2 in vitro, co-precipitated together with HDM2 in lysates, and co-localized with HDM2 in the nucleus when overexpressed. U19 contained a sequence with a putative p53 BOX I-motif for HDM2 binding. Mutation of the two key amino acids within this motif was sufficient to inhibit all the described U19 functions. Our study provides further insight into p53-modulating strategies used by herpesviruses and elucidates a mechanism used by HHV-6B to circumvent the antiviral response.

Abstract
The use of metabolomic based techniques to aid oocyte and embryo selection has gained attention in recent years. Previous work from our laboratory has demonstrated that the (1)H NMR-based metabolic profile of follicular fluid correlates with oocyte developmental potential. Patients undergoing IVF at the Merrion Fertility Clinic had follicular fluid collected at the time of oocyte retrieval. The fatty acid composition of follicular fluid from follicles where oocytes fertilised and developed into multi-cell embryos (n=15) and from oocytes that fertilised normally but failed to cleave (n=9) (cleaved vs non-cleaved) was compared. Statistical analysis was performed on the data using univariate and multivariate techniques. Analysis of the fatty acid composition revealed that there were nine fatty acids significantly different between follicular fluid from the cleaved and the non-cleaved sample groups. Of particular interest were the higher concentration of total saturated (P=0.03) and the lower concentration of total polyunsaturated fatty acids in the non-cleaved sample group (P=0.001). Random forest classification models were used to predict successful cleavage in follicular fluid samples producing models with errors rates of <10%. Receiver operating characteristic analysis demonstrated that the model had good predictability with an area under the curve of 0.96. The panel of fatty acid biomarkers identified in this study indicates that the fatty acid composition of follicular fluid may be more predictive in comparison to other previously identified biomarkers. Following validation in a larger cohort, these biomarkers may have the potential to be used in fertility clinics to aid the selection of oocytes in the future.

Abstract
The Notch receptor is necessary for modulating cell fate decisions throughout development, and aberrant activation of Notch signalling has been associated with many diseases, including tumorigenesis. The E3 ligase MDM2 (murine double minute 2) plays a role in regulating the Notch signalling pathway through its interaction with NUMB. In the present study we report that MDM2 can also exert its oncogenic effects on the Notch signalling pathway by directly interacting with the Notch 1 receptor through dual-site binding. This involves both the N-terminal and acidic domains of MDM2 and the RAM [RBP-Jκ (recombination signal-binding protein 1 for Jκ)-associated molecule] and ANK (ankyrin) domains of Notch 1. Although the interaction between Notch1 and MDM2 results in ubiquitination of Notch1, this does not result in degradation of Notch1, but instead leads to activation of the intracellular domain of Notch1. Furthermore, MDM2 can synergize with Notch1 to inhibit apoptosis and promote proliferation. This highlights yet another target for MDM2-mediated ubiquitination that results in activation of the protein rather than degradation and makes MDM2 an attractive target for drug discovery for both the p53 and Notch signalling pathways.
