Preparation and study of the properties of heterogeneous chiral catalysts containing prolinol derivatives
Celem praczy badawczej była synteza organicznych, chiralnych, heterogenicznych katalizatorów zawierających pochodne prolinolu i zbadanie ich skuteczności w stereoselektywnej reakcji aldolowej 4-nitrobenzaldehydu z acetonem. Otrzymane związki poddano rozdziałowi chromatograficznemu HPLC na kolumnie chiralnej oraz achiralnej. Strukturę produktów i katalizatorów potwierdzono przez analizę widm IR, XRD oraz NMR.The aim of the research work was to synthesize organic, chiral, heterogeneous catalysts containing prolinol derivatives and to test their effectiveness in the stereoselective aldol reaction of 4-nitrobenzaldehyde with acetone. The obtained compounds were subjected to HPLC chromatographic separation on a chiral and achiral column. The structure of the products and catalysts was confirmed by IR, XRD and NMR spectra analysis
The cycle of abuse: Emotional availability in resilient and non-resilient mothers with early öife maltreatment
Adverse childhood experiences mediate the negative association between borderline personality disorder symptoms and plasma oxytocin.
Background Interpersonal dysfunction is a core symptom of borderline personality disorder (BPD) and may be closely linked to adverse childhood experiences. According to a recent model on the pathology of BPD, the neuropeptide oxytocin might play an important role in the development and maintenance of the disorder. However, so far, only few studies with small adult samples have reported reduced baseline oxytocin levels in BPD that may be linked to adverse childhood experiences. Methods We examined baseline plasma oxytocin levels in 131 female patients with BPD and 124 non-BPD female controls across a large age span (12-50 years). Additionally, 113 female patients with less than five DSM-IV BPD features were included to examine the association between plasma oxytocin levels and the number of fulfilled BPD criteria. We also explored associations between plasma oxytocin and adverse childhood experiences as well as depressive symptoms in BPD. Results Patients with BPD had reduced plasma oxytocin levels compared to non-BPD controls and this was independent of age. Plasma oxytocin was negatively associated with the number of fulfilled BPD criteria. The exploratory regression model revealed no association between plasma oxytocin and depressive symptoms but an association between plasma oxytocin and adverse childhood experiences, which in fact mediated the relationship between BPD criteria und plasma oxytocin. Conclusion In a large sample of individuals with BPD across a large age span, our results replicate and extend previous reports of reduced plasma oxytocin levels that might be related to adverse childhood experiences thus providing further evidence for a prominent role of oxytocin in BPD
The Cycle of Abuse: Emotional Availability in Resilient and Non-Resilient Mothers with Early Life Maltreatment
Understanding and breaking the intergenerational cycle of abuse in families enrolled in routine mental health services: study protocol for a randomized controlled trial and two non-interventional trials investigating mechanisms of change within the UBICA II consortium
Background!#!Parents' mental illness (MI) and parental history of early life maltreatment (ELM) are known to be significant risk factors for poor parenting while poor parenting is a crucial mediator of the intergenerational continuity of child maltreatment. Hence, maltreatment prevention programs for families with an MI parent, which pay particular attention to experiences of ELM in the parent, are urgently needed. Parental mentalizing was previously found to mediate successful parenting. Interventions aimed at improving the parental mentalizing capacity reduced maltreatment risk in parents. The aim of the present study is to investigate the effectiveness of a mentalization-based parenting-counseling in acutely mentally ill parents currently treated at a psychiatric hospital.!##!Methods!#!Mentalization-based parenting-counseling (MB-PC) vs. enhanced standard clinical care (SCC+) will be administered in a cluster-randomized-controlled trial (RCT). Patients treated at psychiatric hospitals with children between 1.5 and 15 years will be included in the trial. MB-PC will be administered as a 12-h combined individual and group program enriched by social counseling (over a course of 5 weeks) as add-on to standard clinical care, while the control condition will be standard clinical care plus a 90-min psychoeducation workshop on positive parenting. Primary efficacy endpoint is self-reported parenting practices at follow-up. Embedded within the RCT will be two sub-studies investigating social cognition and dyadic synchrony as biobehavioral mechanisms of change.!##!Discussion!#!The main goal of the present study is to investigate ways to break the intergenerational continuity of maltreatment by assessing the benefits of a prevention program which aims at improving parenting in vulnerable mothers and fathers. MB-PC is a short, low-cost intervention which can be delivered by nurses and social workers and is applicable to MI patients with children with a broad range of diagnoses. If it is shown to be effective, it can be directly implemented into standard psychiatric hospital care thereby providing help to prevent child maltreatment.!##!Trial registration!#!German Clinical Trials Register DRKS00017398 .
