Abstract
SummaryThe effect of thrombin on the phosphorylating activity of platelet membranes was compared to that of trypsin. Preincubation of non-32P phosphorylated platelet membranes with or without either of these two enzymes resulted in a considerable loss of membrane protein kinase activity which was most severe when trypsin was used. Protein kinase activity and endogenous protein acceptors decreased in parallel. 32P-phosphorylated membranes showed a slow but progressive loss of label which was accelerated by trypsin. Thrombin under these conditions prevented the loss of 32P-phosphate. These results are interpreted to indicate a thrombin-induced destruction of a phosphoprotein phosphatase. The protein kinase activity of phosphorylated platelet membranes using endogenous or exogenous protein substrates showed a significant reduction compared to non-phosphorylated membranes suggesting a deactivation of protein kinase by phosphorylation of platelet membranes. Neither thrombin nor trypsin caused a qualitative change in the membrane polypeptides accepting 32P-phosphate but resulted in quantitative alterations of their ability to become phosphorylated.

Abstract
OBJECTIVE Although cognitive dysfunction persists through affective and euthymic states in bipolar disorder (BD), its neurobiological correlates remain undetermined. We explore whole-cortex intracortical myelin (ICM) and cognition in BD-I and controls. METHODS T1 -weighted images (3T) optimized for ICM measurement were analyzed using a surface-based approach. MRI signal was sampled at cortical mid-depth. Cognitive performance was measured via standardized computerized battery and paper-and-pencil Trails B. RESULTS ICM was associated with verbal memory (VM) in BD throughout a cortical network identified with pertinence to VM function, with strongest effects in left caudal middle temporal cortex and left dorsolateral prefrontal cortex (Pcorrected < 0.05). Subanalyses revealed specific association with correct word recognition, without delay. Processing speed, executive function, and reaction time were also predicted by ICM in BD, but not controls, although this did not survive Bonferroni correction. CONCLUSION This is the first study to show VM association with ICM in BD. ICM has been implicated in the integrity of neural connections and neural synchrony. VM dysfunction is one of the most replicated cognitive abnormalities in BD. Therefore, these results provide a novel mechanism for understanding cognitive dysfunction in BD, which can aid in the development of targeted therapeutics to improve cognitive outcomes in BD.

Abstract
Background From 1979-1987, 139 stage IC-IV ovarian cancer patients who had undergone cytoreductive surgery received 6-11 cycles of cisplatin and adriamycin. Study design Eighty-four clinically complete responders underwent second-look laparotomy, and 60 of them received consolidation abdominal irradiation. The patients were then followed for a median follow-up of 39 months. Results Five- and 10-year actuarial survival for all patients was 43% and 24%, for no residuum at primary surgery, 80% and 35%, for residual tumor <2 cm, 45% and 35%, and for residual tumor >2 cm, 20% and 4%. Median survival for stage III-IV patients negative at second-look laparotomy was 72 months in irradiated compared to 25 months in non-irradiated patients (P = 0.14) and 77 months in irradiated patients with microscopic disease at second-look laparotomy. Median survival in patients with macroscopic disease at second-look laparotomy was 23.5 months if irradiated compared to 18 months if not (P = 0.05). Conclusions Consolidation whole abdominal irradiation in advanced stages of ovarian cancer may be of value in patients with negative or microscopic disease at second-look laparotomy. Unfortunately, despite the initial survival advantage observed in irradiated patients, owing to late recurrences there was no significant difference in their long-term survival probability.

Abstract
Abstract
Background: The 21-gene Recurrence Score (RS) Assay (Oncotype DX®) is a validated prognosticator and predictive of chemotherapy (CT) benefit in patients with hormone receptor (HR)+ human epidermal growth factor receptor 2 (HER2)-negative breast cancer. In Israel, the RS assay has been reimbursed by Clalit Health Services (CHS, the largest HMO in Israel) since 2006, and the assay is widely used in eligible estrogen receptor (ER)+ patients. Notably, ER+ breast cancer patients have a protracted risk of recurrence with approximately half of all distant recurrences occurring after 5 years from diagnosis. The goal of the current ongoing analysis was to investigate early (≤5 years) and late (>5 years) distant recurrence in N0/N1mi ER+ HER2-negative breast cancer patients who were RS-tested through CHS.
Methods: This analysis of the CHS registry included breast cancer patients with ER+ HER2-negative N0/N1mi disease who underwent RS testing from 1/2006 (CHS approval of the assay) through 1/2009. Data sources included CHS claims arms (for patient/tumor characteristics), Teva Pharmaceuticals (for tumor characteristics, RS result), and medical records (for treatment/recurrence/survival). The study was approved by the institutional review boards of the CHS Community Division and was granted a waiver for obtaining patient consent.
Results: The analysis included 1026 patients with median (interquartile range) follow up of 9.3 (8.8-10.2) years. Most patients were females (99%). Median (range) age was 59 (25-84) years; 92% had N0 and 8% had N1mi disease; 14%, 52%, and 16% had grade 1, 2, and 3 tumors, respectively (grade information was not available for 18% of patients); median (range) tumor size was 1.5 (0.3-6.5) cm. The majority of patients (78%) had invasive ductal carcinoma and 12% had invasive lobular carcinoma. Overall, 489 patients (48%) had RS<18, 434 (42%) had RS 18-30, and 103 (10%) had RS≥31. The use of adjuvant CT was consistent with the RS result: 3%, 27%, and 90% of RS<18, RS 18-30, and RS≥31 patients, respectively. Overall, 25 distant recurrences were reported within 5 years of RS testing: 5 (1.0%) in RS<18 patients, 9 (2.1%) in RS 18-30 patients, and 11 (10.6%) in RS≥31 patients. In the first 5 years, breast cancer-specific death was reported in 8 patients including 3 (0.7%) with RS 18-30 and 5 (4.9%) with RS≥31 results. Among N0 patients with RS 11-25 who did not receive adjuvant CT (n = 540), 5 (0.9%) distant recurrences and one (0.2%) breast cancer death were reported within 5 years of RS testing. Analysis of 'late' recurrences and breast cancer-specific death (from 5 to 9.3 years of follow-up) is ongoing.
Conclusions: These will be the first late recurrence data from over 1000 patients for whom the RS result was used in real-life clinical decision making. Consistent with previous analyses of the CHS registry, CT use was appropriately based on the RS result, and the recurrence/survival outcomes (for the first 5 years) demonstrated the prognostic performance of the RS. Distant recurrence and breast cancer death data beyond 5 years will be presented at the meeting.

Abstract
Background Ragweed pollen represents a major allergy risk factor. Ragweed extracts contain five different isoforms of the major allergen Amb a 1. However, the immunological characteristics of Amb a 1 isoforms are not fully investigated. Here, we compared the physicochemical and immunological properties of three most important Amb a 1 isoforms. Methods After purification, the isoforms were physicochemically characterized, tested for antibody binding and induction of human T‐cell proliferative responses. Their immunological properties were further evaluated in vitro and in vivo in a mouse model. Results Amb a 1 isoforms exhibited distinct patterns of IgE binding and immunogenicity. Compared to Amb a 1.02 or 03 isoforms, Amb a 1.01 showed higher IgE‐binding activity. Isoforms 01 and 03 were the most potent stimulators of patients’ T cells. In a mouse model of immunization, Amb a 1.01 induced higher levels of IgG and IgE antibodies when compared to isoforms 02 and 03. Interestingly, ragweed‐sensitized patients also displayed an IgG response to Amb a 1 isoforms. However, unlike therapy‐induced antibodies, sensitization‐induced IgG did not show IgE‐blocking activity. Conclusion The present study showed that naturally occurring isoforms of Amb a 1 possess different immunogenic and sensitizing properties. These findings should be considered when selecting sequences for molecule‐based diagnosis and therapy for ragweed allergy. Due to its high IgE‐binding activity, isoform Amb a 1.01 should be included in diagnostic tests. In contrast, due to their limited B‐ and T‐cell cross‐reactivity patterns, a combination of different isoforms might be a more attractive strategy for ragweed immunotherapy.

Abstract
Modelling the radionuclide cycle in forests is important in case of contamination due to acute or chronic releases to the atmosphere and from underground waste repositories. This article describes the most important aspects to consider in forest model development. It intends to give an overview of the modelling approaches available and to provide guidance on how to address the quantification of radionuclide transport in forests. Furthermore, the most important gaps in modelling the radionuclide cycle in forests are discussed and suggestions are presented to address the variability of forest sites.

Abstract
Major depressive disorder (MDD) is estimated to affect one in twenty people worldwide. MDD is highly comorbid with cardiovascular disease (CVD), itself one of the single largest causes of mortality worldwide. A number of pathological changes observed in MDD are believed to contribute to the development of cardiovascular disease, although no single mechanism has been identified. There are also no biological markers capable of predicting the future risk of developing heart disease in depressed individuals. Plasminogen activator inhibitor-1 (PAI-1) is a prothrombotic plasma protein secreted by endothelial tissue and has long been implicated in CVD. An expanding body of literature has recently implicated it in the pathogenesis of major depressive disorder as well. In this study, we review candidate pathways implicating MDD in CVD and consider how PAI-1 might act as a mediator by which MDD induces CVD development: chiefly through sleep disruption, adiposity, brain-derived neurotrophic factor (BDNF) metabolism, systemic inflammation and hypothalamic-pituitary-adrenal (HPA)-axis dysregulation. As both MDD and CVD are more prevalent in women than in men, and incidence of either condition is dramatically increased during reproductive milestones, we also explore hormonal and sex-specific associations between MDD, PAI-1 and CVD. Of special interest is the role PAI-1 plays in perinatal depression and in cardiovascular complications of pregnancy. Finally, we propose a theoretical model whereby PAI-1 might serve as a useful biomarker for CVD risk in those with depression, and as a potential target for future treatments.

Abstract
IntroductionMaternal mental well being influences offspring development. Research suggests that an interplay between genetic and environmental factors underlies this familial transmission of mental disorders.ObjectivesTo explore an interaction between genetic and environmental factors to predict trajectories of maternal mental well being, and to examine whether these trajectories are associated with epigenetic modifications in mothers and their offspring.MethodWe assessed maternal childhood trauma and rearing experiences, prenatal and postnatal symptoms of depression and stress experience from 6 to 72 months postpartum, and genetic and epigenetic variation in a longitudinal birth-cohort study (n = 262) (Maternal adversity, vulnerability and neurodevelopment project). We used latent class modeling to describe trajectories in maternal depressive symptoms, parenting stress, marital stress and general stress, taking polygenetic risk for major depressive disorder (MDD), a composite score for maternal early life adversities, and prenatal depressive symptoms into account.ResultsGenetic risk for MDD associated with trajectories of maternal well being in the postpartum, conditional on the experience of early life adversities and prenatal symptoms of depression. We will explore whether these trajectories are also linked to DNA methylation patterns in mothers and their offspring. Preliminary analyses suggest that maternal early life adversities associate with offspring DNA methylation age estimates, which is mediated through maternal mental well being and maternal DNA methylation age estimates.ConclusionWe found relevant gene-environment interactions associated with trajectories of maternal well being. Our findings inform research on mechanisms underlying familial transmission of vulnerability for psychopathology and might thus be relevant to prevention and early intervention programs.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Animal and human studies suggest that initial expression of maternal behaviour depends on oxytocin and dopamine systems. However, the mechanism by which these systems affect parenting behaviours and the timing of these effects are not well understood. This article explores the role of mothers' executive function in mediating the relation between oxytocin and dopamine gene variants and maternal responsiveness at 48 months post-partum. Participants (n = 157) were mothers recruited in the Maternal Adversity, Vulnerability and Neurodevelopment Study, which assesses longitudinally two cohorts of mothers and children in Canada. We examined single nucleotide polymorphisms (SNPs) related to the dopamine and oxytocin systems (DRD1 rs686, DRD1 rs265976, OXTR rs237885 and OXTR rs2254298), assessed mothers' decision-making at 48 months using the Cambridge Neurological Automated Testing Battery (CANTAB) and evaluated maternal responsiveness from videotaped interactions during the Etch-A-Sketch co-operation task. Mediation analyses showed that OXTR rs2254298 A-carriers had an indirect effect on positive parenting which was mediated by mothers' performance on decision-making task (estimate = 0.115, P < 0.005), while OXTR rs2254298 A-carriers had both direct and indirect effects on physically controlling parenting, also mediated through enhanced performance on decision-making (estimate = -0.059, P < 0.005). Dopamine SNPs were not associated with any measure of executive function or parenting (all P > 0.05). While oxytocin has previously been associated with only the early onset of maternal behaviour, we show that an OXTR polymorphism is involved in maternal behaviour at 48 months post-partum through mothers' executive function. This research highlights the importance of the oxytocin system to maternal parenting beyond infancy.

Abstract
Background and Aims Country of birth provides a proxy for ethnic group for recent migrants. Major differences in mortality by country of birth have been demonstrated in England and Wales, but similar published data for Scotland are lacking. We aimed to examine variations in mortality by country of birth for Scottish residents. Methods We calculated standardised mortality ratios by country of birth for Scottish residents aged 25 years and over between January 1997 and March 2003. Results and Conclusion Comparisons with England and Wales showed high allcause, coronary heart disease (CHD) and stroke mortality among Scottish residents born in Scotland, Northern Ireland, the Republic of Ireland, India and Hong Kong. However, most country of birth groups had similar or lower mortality than the Scottish born. These are the first data on mortality by country of birth in Scotland and they demonstrate major variations. Comparisons within the Scottish population might be interpreted as reassuring, since they do not show the excesses in CHD mortality by country of birth reported in England and Wales. However, the use of England and Wales as a comparison group shows a substantial excess of CHD risk among South Asians in Scotland, comparable to that reported in England and Wales.
