ABSTRACT

(1) Background: BPD is characterized by affect dysregulation, interpersonal problems, and disturbances in attachment, but neuroimaging studies investigating attachment representations in BPD are rare. No study has examined longitudinal neural changes associated with interventions targeting these impairments. (2) Methods: We aimed to address this gap by performing a longitudinal neuroimaging study on n = 26 patients with BPD treated with Dialectic Behavioral Therapy (DBT) and n = 26 matched healthy controls (HCs; post intervention point: n = 18 BPD and n = 23 HCs). For functional imaging, we applied an attachment paradigm presenting attachment related scenes represented in drawings paired with related neutral or personalized sentences from one's own attachment narratives. In a prior cross-sectional investigation, we identified increased fMRI-activation in the human attachment network, in areas related to fear response and the conflict monitoring network in BPD patients. These were especially evident for scenes from the context of loneliness (monadic pictures paired with individual narrative sentences). Here, we tested whether these correlates of attachment representation show a near-to-normal development over one year of DBT intervention. In addition, we were interested in possible associations between fMRI-activation in these regions-of-interest (ROI) and clinical scores. (3) Results: Patients improved clinically, showing decreased symptoms of borderline personality organization (BPI) and increased self-directedness (Temperament and Character Inventory, TCI) over treatment. fMRI-activation was increased in the anterior medial cingulate cortex (aMCC) and left amygdala in BPD patients at baseline which was absent after intervention. When investigating associations between scores (BPI, TCI) and functional activation, we found significant effects in the bilateral amygdala. In contrast, aMCC activation at baseline was negatively associated with treatment outcome, indicating less effective treatment effects for those with higher aMCC activation at baseline. (4) Conclusions: Monadic attachment scenes with personalized sentences presented in an fMRI setup are capable of identifying increased activation magnitude in BPD. After successful DBT treatment, these increased activations tend to normalize which could be interpreted as signs of a better capability to regulate intensive emotions in the context of "social pain" towards a more organized/secure attachment representation. Amygdala activation, however, indicates high correlations with pre-treatment scores; activation in the aMCC is predictive for treatment gain. Functional activation of the amygdala and the aMCC as a response to attachment scenes representing loneness at baseline might be relevant influencing factors for DBT-intervention outcomes.

ABSTRACT

Background: Fear of abandonment and aloneness play a key role in the clinical understanding interpersonal and attachment-specific problems in patients with borderline personality disorder (BPD) and has been investigated in previous functional Magnet Resonance Imaging (fMRI) studies. The aim of the present study was to examine how different aspects of attachment representations are processed in BPD, by using for the first time an fMRI attachment paradigm including personalized core sentences from the participants' own attachment stories. We hypothesized that BPD patients would show increased functional involvement of limbic brain regions associated with fear and pain (e.g., the amygdala and the anterior cingulate cortex) when presented personalized attachment relevant stimuli representing loneliness compared to healthy controls (HC). Methods: We examined the attachment classifications of 26 female BPD patients and 26 female HC using the Adult Attachment Projective Picture System (AAP). We used an fMRI-adapted attachment paradigm to investigate the neural correlates of attachment. All participants were presented three personalized (vs. neutral) sentences extracted from their AAP attachment narrative, combined with standardized AAP pictures representing being alone (monadic) or in interactive (dyadic) attachment situations. Results: As expected, the classification of unresolved attachment was significantly greater in BPD compared to HC. BPD patients showed increased fMRI-activation in brain areas associated with fear, pain, and hyperarousal than HC when presented with personalized attachment-relevant alone stimuli. In particular, pictures with monadic attachment situations induced greater anterior medial cingulate cortex, anterior insula, amygdala, thalamus and superior temporal gyrus activation in the patient group. Conclusion: The results point to increased fMRI-activation in areas processing emotional distress and painful experiences in BPD patients. In particular, the emotional cascade reflecting attachment distress was evoked by combining monadic pictures, representing abandonment and aloneness, with the patients' personalized narrative material. Our results confirmed and replicated previous results that illustrate once again the high relevance of aloneness and feelings of abandonment for BPD in the context of attachment trauma. Moreover, our results support the hypothesis of hypermentalization in response to attachment distress as a core feature of social-cognitive impairment in BPD associated with common treatment implications across different therapeutic orientations.

ABSTRACT

Attachment characteristics play a key role in understanding borderline-specific problems with respect to childhood maltreatment. The aim of this study was to investigate how attachment representations may influence the trajectory of change in a 1-year outpatient dialectical behavior therapy (DBT) for patients with borderline personality disorder (BPD). Attachment representations were assessed in 26 BPD patients and 26 healthy controls (HC) using the Adult Attachment Projective Picture System (AAP) before treatment. Borderline and global symptom severity and interpersonal problems were examined before, during, and after completing the intervention. Analysis of variance and stepwise hierarchical regression analyses were used to explore the course of symptomatology. As expected, BPD patients displayed a predominance of unresolved attachment in the AAP compared with HC, by showing a lack of ability to integrate attachment related trauma. Whereas both resolved and unresolved attachment groups revealed significant improvement in symptom severity during treatment, dimensional AAP scores showed differences. Patients with higher scores in "synchrony" demonstrated more indicators of mutual care in their narratives to dyadic pictures and displayed a significantly stronger decrease of interpersonal problems than patients with lower synchrony scores. Assessing attachment representations prior to DBT might provide a helpful insight into individual attachment related resources or lack of these capacities. Responsiveness and synchrony in dyadic interactions with significant others are crucial for healthy interpersonal relations. A stronger therapeutic focus on the patient's capacity to show synchrony in dyadic attachment situations might improve the patient's interpersonal problems towards sensitive and mutual interaction.

ABSTRACT

Structural alterations in the corpus callosum (CC), the major white matter tract connecting functionally related brain regions in the two hemispheres, have been shown to be associated with emotional instability, impulsivity and suicidality in various mental disorders. To explore whether structural alterations of the CC would be similarly associated with emotional instability, impulsivity and suicidality in borderline personality disorder (BPD), we used diffusion tensor imaging (DTI) to assess the structural integrity of the CC in 21 BPD and 20 healthy control (HC) participants. Our hypothesis-driven analyses revealed a positive correlation between BPD participants' suicidal behavior and fractional anisotropy (FA) in the splenium and genu of the CC and a negative correlation between BPD participants' suicidal behavior and mean diffusivity (MD) in the splenium of CC. Our exploratory analyses suggested that suicidal BPD participants showed less FA and more MD in these regions than HC participants but that non-suicidal BPD participants showed similar FA and MD in these regions as HC participants. Taken together, our findings suggest an association between BPD participants' suicidal behavior and structural alterations in regions of the CC that are connected with brain regions implicated in emotion regulation and impulse control. Structural alterations of the CC may, thus, account for deficits in emotion regulation and impulse control that lead to suicidal behavior in BPD. However, these findings should be considered as preliminary until replicated and extended in future studies that comprise larger samples of suicidal and non-suicidal BPD participants.

ABSTRACT

Objective Investigate influence and change of self-directedness (SD) in Dialectical-Behavior Therapy (DBT) for 26 female outpatients with borderline personality disorder (BPS). Method Variance analyses are used to evaluate psychopathology and interpersonal problems in 2 subgroups (low vs. high SD) with questionnaires at 3 measuring times over the period of 1 year. Results Low SD was associated with higher psychopathology, more interpersonal problems and lower symptomreduction. Over time of intervention the SD of all patients improved significantly. Conclusion DBT strengthens the SD of patients with BPD. A screening of SD before intervention, and systematic support should be considered.

ABSTRACT

Six new naphthalenone derivatives, balticols A-F and the known metabolite altechromone A were isolated from the AcOEt extract of the culture broth of fungal strain 222 belonging to the Ascomycota, which was found on driftwood collected at the coast of the Greifswalder Bodden, Baltic Sea, Germany. All structures were elucidated on the basis of NMR spectroscopic data and mass spectrometric analyses. The balticols were found to exhibit inhibitory activity against influenza virus A and herpes simplex virus. The most potent antiviral activity was observed for balticol E with an IC(50) value of 0.01 microg/ml against Herpes simplex virus type I.

ABSTRACT

Bioassay-guided isolation of antiviral compounds from the cultured cyanobacterium Microcystis ichthyoblabe provided two novel cyclic depsipeptides, ichthyopeptins A (1) and B (2). Their structures were determined by 1D (1H and 13C) and 2D (COSY, TOCSY, ROESY, HMQC, and HMBC) NMR spectra, ESIMS-MS, and amino acid analysis. The fraction containing both cyclic depsipeptides exhibited antiviral activity against influenza A virus with an IC50 value of 12.5 microg/mL.

ABSTRACT

Methanol and hot-aqueous extracts of 25 different plant species, used in Yemeni traditional medicine and growing, partly as endemic plants, on the island Soqotra have been investigated for their antiviral activity. In addition, the phytochemical identification of the main chemical constituents was performed. The extracts were assayed in two in vitro viral systems, which used influenza virus type A/MDCK cells and herpes simplex virus type 1/Vero cells, at non-cytotoxic concentrations. The herpes simplex virus type 1 showed more sensitivity than the influenza virus type A against the extracts investigated. The methanol extracts of Boswellia ameero, Boswellia elongata, Buxus hildebrandtii, Cissus hamaderohensis, Cleome socotrana, Dracaena cinnabari, Exacum affine, Jatropha unicostata and Kalanchoe farinacea showed anti-influenza virus type A activity with 50% inhibition (IC50) concentrations ranging from 0.7 to 12.5 microg/mL. In addition, 17 plants of the 25 investigated exhibited anti-HSV-1 activity. The antiviral activity of some active extracts was also observed on a molecular level.

ABSTRACT

DNA sequences coding for simian virus 40 (SV40) large T antigen have been detected at different frequencies in human non-Hodgkin's lymphomas (NHL) by PCR techniques as well as immunohistochemistry. A highly sensitive quantitative real-time PCR specific for a sequence of SV40 large T antigen was established to test whether SV40 DNA is present in malignant lymphomas of German patients. Thirty-three lymph node samples obtained from 27 patients with NHL and 6 patients with Hodgkin's disease (HD) were tested in addition to 48 samples of peripheral blood mononuclear cells (PBMNC) from patients with NHL containing between 0.1% and >90% circulating lymphoma cells determined by PCR. Fourteen lymph nodes obtained from patients with other diseases than malignant lymphomas and 47 PBMNC samples from healthy volunteers served as controls. All samples from patients with malignant lymphomas and all controls were negative for SV40 DNA by quantitative real-time. In contrast, EBV-DNA could be detected in 29 of 46 DNA preparations isolated from lymph nodes (63%) and in 20 of 47 DNA preparations from PBMNC. EBV-positive samples contained between 5 and 80,000 EBV copies per 100,000 cells. Our results do not support the hypothesis that SV40 plays a major role in the etiology of malignant lymphomas and, in addition, they exclude a clonal SV 40 infection of malignant lymphoma cells in all samples investigated.

ABSTRACT

Four sterols and 10 triterpenes were isolated from the fruiting bodies of Ganoderma pfeifferi, including the three new triterpenes 3,7,11-trioxo-5alpha-lanosta-8,24-diene-26-al (lucialdehyde D, 1), 5alpha-lanosta-8,24-diene-26-hydroxy-3,7-dione (ganoderone A, 2), and 5alpha-lanosta-8-ene-24,25-epoxy-26-hydroxy-3,7-dione (ganoderone C, 3). The structures of 1-3 were determined on the basis of spectroscopic evidence. Antibacterial, antifungal, and antiviral activity were studied for some of the isolated compounds. Ganoderone A (2), lucialdehyde B (4), and ergosta-7,22-dien-3beta-ol (7) were found to exhibit potent inhibitory activity against herpes simplex virus.

ABSTRACT

BACKGROUND: The development of atherosclerosis has an inflammatory component. Currently it is not clear, whether hepatitis B and C virus infections are associated with the risk of atherosclerosis. The aim of the present analysis was to investigate those relationships in a population sample. METHODS AND RESULTS: The study of health in Pomerania (SHIP) is a cross-sectional study of the adult population in the northeast of Germany. HBs antigen (HBsAg) and IgG antibodies against hepatitis B and C virus (anti-HBs and anti-HCV) were determined by enzyme linked immunosorbent assays. Fifteen subjects (0.4%) were positive for HBsAg, and 21 subjects (0.5%) were positive for anti-HCV. Among the persons who had no history of anti-hepatitis B vaccination, 213 individuals (5.0%) were found to be as positive for anti-HBs. These individuals and those with prevalent anti-HCV antibodies were regarded as cases (n = 233). The control group comprised of 4033 individuals. Multivariable analyses revealed that there was no independent association between anti-HBs and anti-HCV antibody seropositivity and atherosclerotic end-points such as prevalent myocardial infarction, stroke, carotid intima-media thickness (IMT), carotid plaques and stenoses. CONCLUSION: There is no association between serological markers for hepatitis B and C virus infection and the risk of atherosclerosis in this population sample.

ABSTRACT

Since viral infections are believed to be one of the causes of sudden hearing loss we have used serological assays for herpes simplex virus (HSV), varicella zoster virus (VZV), and enterovirus as well as polymerase chain reaction for enterovirus to test 55 sudden hearing loss patients for viral infections. Serological screening of these patients for HSV and VZV failed to reveal significant differences between the patient group and the controls. In contrast, enterovirus sequences were detected by RT-PCR in 40% of the patient group, but in none of the controls, suggesting that enterovirus infections may be associated with sudden hearing loss.

ABSTRACT

The influence of the oral administration of an aqueous-ethanolic extract of a mixture of Thujae occidentalis herba, Baptisiae tinctoriae radix, Echinaceae purpureae radix and Echinaceae pallidae radix, on the course of Influenza A virus infection in Balb/c mice was investigated. The extract was administered to mice via the drinking water for 14 days starting 6 days before intranasal infection with Influenza A virus. The progress of infection was recorded during a time range of 21 days. Parameters for the evaluation of antiviral activity were survival rate and mean day to death. In a further set of experiments infected mice were sacrificed on defined days. Determination of consolidation score and virus titer were performed for each lung. The data show that the oral treatment with the extract induced a statistically significant increase in the survival rate, prolonged the mean survival time and reduced lung consolidation and virus titer. The experiments demonstrate that the plant immunomodulator given 6 days before exposure is a potent inhibitor of Influenza A virus pathology in vivo.
