AB  - Background Research results on dehydroepiandrosterone sulfate ester (DHEAS) in post-traumatic stress disorder (PTSD) are inconsistent. We hypothesized that personality traits could be the confounders of DHEAS levels and disease symptoms, which could in part explain the discrepancy in findings. Method: This study was a part of a broader project in which simultaneous psychological and biological in-vestigations were carried out in hospital conditions. 380 male subjects were categorized in four groups: A) current PTSD (n = 132), B) lifetime PTSD (n = 66), C) trauma controls (n = 101), and D) healthy controls (n = 81), matched by age. Results: The level of DHEAS is significantly lower in the current PTSD group than in trauma controls. All groups significantly differ in personality traits Disintegration and Neuroticism (current PTSD group having the highest scores). DHEAS is related to both PTSD and depressive symptoms; however, Structural Equation Model (SEM) shows that the relations are indirect, realized via their confounder-personality trait Disintegration. Conclusions: According to our project results, DHEAS is the second putative biomarker for trauma-related dis-orders that fails to fulfil this expectation. It appears to be more directly related to personality than to the disease symptoms (the first one being basal cortisol). Our data promote personality as a biologically based construct with seemingly important role in understanding the mental health status.

AB  - Differential triangular flow, v(3)(p(T)), of negative pions is measured at root s(NN) = 17.3 GeV around midrapidity by the CERES/NA45 experiment at CERN in central PbAu collisions in the range 0-30% with a mean centrality of 5.5%. This is the first measurement as a function of transverse momentum of the triangular flow at SPS energies. The p(T) range extends from about 0.05 GeV/c to more than 2 GeV/c. The triangular flow magnitude, corrected for the HBT effects, is smaller by a factor of about 2 than the one measured by the PHENIX experiment at RHIC and the ALICE experiment at the LHC. Within the analyzed range of central collisions no significant centrality dependence is observed. The data are found to be well described by a viscous hydrodynamic calculation combined with an UrQMD cascade model for the late stages. (C) 2016 Elsevier B.V. All rights reserved.

AB  - A disturbed beta-endorphin system can be a part of the post-traumatic stress disorder (PTSD) and depression allostasis. Study subjects (N=392) included those with PTSD and/or (stress-induced) depression, and healthy controls with and without traumas. The aim of the study was to examine the network of relations centered around plasma beta-endorphin. The network included anxiety (as a personality trait), traumatic events, pain, aggressiveness, depressive symptoms, and three clusters of PTSD symptoms: intrusions, avoidance, and hyperarousal. Beta-endorphin was represented by individual mean from 13 time points (BEmean), reflecting the total amount of the peripherally secreted hormone, and the coefficient of variation (BEvar), calculated as the ratio of standard deviation to the mean, reflecting the hormones dynamics. BEvar correlated with all other variables, BEmean had no correlations. Structural equation modeling (SEM) was used to examine all interrelations (including their directions) of BEvar and the state/trait variables in the context of their entirety. The model revealed that hyperarousal and anxiety were the only direct agents of peripheral beta-endorphin fluctuations, mediating the effects of other variables. Traumatic events and intrusions act on BEvar via hyperarousal, while depressive symptoms, avoidance, and pain act via anxiety. Hyperarousal should be emphasized as the main agent not only because its effect on BEvar is larger than that of anxiety, but also because it increases anxiety itself (via avoidance and pain). All influences on BEvar are positive and they indicate long-term (sensitizing) effects (as opposed to direct stimulation, for example, by acute pain, anger, etc.). Relations apart from beta-endorphin are also discussed. (C) 2015 Elsevier B.V. All rights reserved,

AB  - Alterations in the number and functional status of mineralocorticoid (MR) and glucocorticoid receptors (GR) may contribute to vulnerability to posttraumatic stress disorder (PTSD). Corticosteroid receptors are chaperoned by heat shock proteins Hsp90 and Hsp70. We examined relations between corticosteroid receptor and heat shock protein expression levels, and related them with war trauma exposure, PTSD and resilience to PTSD. Relative levels of MR. Hsp90 and Hsp70 were determined by immunoblotting in lymphocytes from war trauma-exposed men with current PTSD (current PTSD group, n=113), with lifetime PTSD (life-time PTSD group, n=61) and without PTSD (trauma control group, n=88), and from non-traumatized healthy controls (healthy control group, n=85). Between-group differences in MR, Hsp90 and Hsp70 levels and in MR/GR ratio were not observed. The level of MR was correlated with both Hsp90 and Hsp70 levels in trauma control and healthy control groups. On the other hand, GR level was correlated only with Hsp90 level, and this correlation was evident in current PTSD and trauma control groups. In conclusion, PTSD and exposure to trauma are not related to changes in lymphocyte MR, Hsp90 or Hsp70 levels, but may be associated with disturbances in corticosteroid receptors interaction with heat shock proteins.

AB  - Background: The hypothalamo-pituitary-adrenocortical (HPA) axis self-regulation is achieved via cortisol binding to mineralocorticoid (MR) and glucocorticoid receptors (GR). It is often disturbed in mental disorders, particularly in those where traumatic stress has been implicated, such as posttraumatic stress disorder and depression. Although dexamethasone suppression test (DST) is often used as diagnostic aid, the findings still vary. In search of the factors influencing the DST outcome, we examined the glucocorticoicl receptor (GR) gene Bell polymorphism. Methods: A total of 229 male subjects were classified into three Bell groups: two groups with homozygous carriers (of the G allele, N=108, and of the C allele, N=26), and one with heterozygous carriers (N=95). Multiple hierarchical linear regression analysis was clone, where the dependent variable was the clexamethasone-inclucecl cortisol suppression, and predictors included receptor variables. The interactions of the count of Gs with the predictors were introduced to single out the effects of the G allele. Results: The means of all studied variables, including suppression, are statistically the same in the three groups. However, the mechanism of suppression involves MRs only in the G allele carriers. Limitations: The subjects were selected by criteria suited for the aim of the large project whose part is this study, hence the relatively small number of CC carriers. Also, we did not assess MR functional properties that would probably sharpen the results. Conclusion: Our finding that MRs participate in cortisol suppression in the G allele carriers suggests that research aimed at refining HPA axis-based therapy might require its adjustment for such patients., (C) 2014 Elsevier By.

Conclusion: Our finding that MRs participate in cortisol suppression in the G allele carriers suggests that research aimed at refining HPA axis-based therapy might require its adjustment for such patients., (C) 2014 Elsevier By.

AB  - Objective: Posttraumatic stress disorder (PTSD) has been shown to be associated with altered glucocorticoid receptor (GR) activity. We studied the expression and functional properties of the receptor in peripheral blood mononuclear cells (PBMCs) from non-traumatized healthy individuals (healthy controls; n = 85), and war trauma-exposed individuals with current PTSD (n = 113), with life-time PTSD (n = 61) and without PTSD (trauma controls; n = 88). The aim of the study was to distinguish the receptor alterations related to PTSD from those related to trauma itself or to resilience to PTSD. Methods: Functional status of the receptor was assessed by radioligand binding and lysozyme synthesis inhibition assays. The level of GR gene expression was measured by quantitative PCR and immunoblotting. Results: Current PTSD patients had the lowest, while trauma controls had the highest number of glucocorticoid binding sites (B-max) in PBMCs. Hormone-binding potential (B-max/K-D ratio) of the receptor was diminished in the current PTSD group in comparison to all other study groups. Correlation between B-max and K-D that normally exists in healthy individuals was decreased in the current PTSD group. Contrasting B-max data, GR protein level was lower in trauma controls than in participants with current or life-time PTSD. Conclusions: Current PTSD is characterized by reduced lymphocyte GR hormone-binding potential and by disturbed compensation between B-max and hormone-binding affinity. Resilience to PTSD is associated with enlarged fraction of the receptor molecules capable of hormone binding, within the total receptor molecule population in PBMCs. (C) 2013 Elsevier Inc.

AB  - Background: Studies of cortisol in post-traumatic stress disorder (PTSD) have yielded mixed results. We hypothesize that personality traits and traumatic experiences could be the confounders of cortisol measures and disease symptoms. Method: This study was a part of a broader project in which simultaneous psychological and biological investigations were carried out in hospital conditions on 400 male participants categorized by four groups: (A) 133 with current PTSD, (B) 66 with lifetime PTSD, (C) 102 trauma controls, and (D) 99 healthy controls (matched by age and education). Cortisol and ACTH were measured in blood samples taken hourly from 22:00 h to 09:00 h, with an additional sample at 07:30 h (resting state and morning rise). The next night, dexamethasone (0.5 mg) suppression test was performed. Results: No significant differences in basal cortisol and ACTH were found between study groups. The trait Conscientiousness, negatively modulated by Extraversion (assessed by NEO Personality Inventory-Revised) was found to correlate with cortisol (but not with ACTH). Group differences are found on suppression. Structural equation modeling shows excellent fit only when the paths (influences) from Conscientiousness to basal cortisol and from traumatic events to suppression are present. The paths connecting suppression and PTSD symptoms do not contribute. Conclusions: Two sources of differences of hypothalamo-pituitary-adrenocortical axis functioning are implied, both only indirectly connected to PTSD. It seems that basal cortisol secretion is associated more tightly with personality (introvertively modulated Conscientiousness), while the regulation by glucocorticoid receptor system is sensitized by repeated traumatic situations.

AB  - The use of the low-dose dexamethasone suppression test (DST) as a potentially discriminative marker between post-traumatic stress disorder (PTSD) and depression is still under discussion. In order to compare the influence of these psychopathologies on the DST results, we examined suppression in war-traumatized subjects with one or both of these disorders, as well as in healthy controls. Based on our previous findings, we hypothesized that subjects with any disorder would exhibit higher dexamethasone suppression than healthy controls due to traumatic experiences. This study was a part of a broader project in which simultaneous psychological and biological investigations were carried out in hospital conditions on 399 mate participants: 57 with PTSD, 28 with depression, 76 with PTSD + depression, and 238 healthy controls. Cortisol was measured in blood samples taken at 0900 h before and after administering 0.5 mg of dexamethasone (at 2300 h). Group means standard deviation of cortisol suppression were: 79.4 +/- 18.5 in the PTSD group, 80.8 +/- 11.6 in the depression group, 77.5 +/- 24.6 in the group with PTSD+depression, and 66.8 +/- 34.6 in healthy controls. The first three groups suppressed significantly more than the fourth. When the number of traumas was introduced as a covariate, the differences disappeared. The hypothesis was confirmed: in respect to DST, the examined trauma-related psychopathologies showed the same pattern: hypersuppression, due to multiple traumatic experiences. (C) 2012 Elsevier Ltd.

AB  - Our aim was to assess clinical utility of Tc-99m-EDDA/HYNIC-TOC scintigraphy for evaluation of lung lesions in patients with neuroendocrine tumors (NETs). Single photon emission computed tomography (SPECT) of the thorax and whole body scintigraphy were performed in 34 patients using Tc-99m-EDDA/HYNIC-TOC. Visual assessment was complemented by semiquantitative evaluation based on tumor to non-tumor (TINT) ratio. Clinical, laboratory, and histological findings served as the standard for comparison. Enhanced tracer uptake was observed on both SPECT and whole body scintigraphy in 29 of 34 patients (88% sensitivity). TINT ratios were significantly higher on SPECT than whole body images (2.96 +/- 1.07 vs. 1.70 +/- 0.43, p LT 0.01) and did not correlate with NET proliferation index Ki-67 (r= - 0.36, p=0.27). Conclusion: Tc-99m-EDDA/HYNIC-TOC scintigraphy is useful for evaluation of NET tissue in the lungs. SPECT provides better visualization of lung lesions than whole body scintigraphy. The intensity of tracer uptake, however, does not relate to the proliferation rate of NETs. Tc-99m-EDDA/HYNIC-TOC scintigraphy may be helpful for selecting and monitoring treatment options, particularly when radiolabeled somatostatin analogue therapy becomes available.
