Objective：The aim of this study was to evaluate the concentrations of C-reactive protein （CrP）, tumor necrosis factor-α （TNF-α）, interleukin-6 （IL-6）, and the degree of homeostasis model assessment-insulin resistance （HOMA-Ir） in patients with morbid obesity exposed to a three-week low-calorie diet and balneotherapy. Methods：The study included 33 patients （25 females and 8 males; mean age 46 years） with body mass index （BMI） values of〉40 kg/m2. Evaluations of CrP, IL-6, TNF-α, lipid profile, HOMA-Ir, and fasting glucose were carried out before （baseline data） and three weeks after the treatment. The control group consisted of 20 healthy volunteers （15 females and 5 males） with a mean age of 39 years and BMI values of≤24.9 kg/m2. results：In the blood of patients with morbid obesity we found significantly elevated levels of CrP, TNF-α, triglycerides, HOMA-Ir and fasting glucose, but a de-creased level of high density lipoprotein （HDL）-cholesterol, compared with the healthy individuals. The treatment resulted in about a 9.4%reduction in body weight from 122.5 to 111.0 kg and a significant decrease in the concen-tration of CrP, but no change in TNF-αor IL-6. HOMA-Ir was significantly reduced. Conclusions：The decrease in CrP level without changes in TNF-α or IL-6 concentrations after the low-calorie diet and balneological treatment, suggests that an essential amount of adipose tissue must be removed before proper adipocyte function is restored. The decrease in HOMA-Ir indicates an improvement in insulin sensitivity, which is beneficial in obese patients.

AIM: To explore(1) intergroup differences in comfortable interpersonal distances(CIDs) and the use of coping strategies;(2) the association of these parameters with individual symptomatology; and(3) the interplay between CIDs and coping styles in patients with depression and schizophrenia. METHODS: The parameters of interest were assessed by means of standardized questionnaires: CID and Coping Inventory for Stressful Situations. Psychopathology was evaluated with the Beck Depression Inventory and Positive and Negative Syndromes Scale. ANOVA, Pearson's correlations and multiple regression analyses were used to examine relationships among the ***: Compared with controls, depressed patients were more distanced from family members, significant others and self-images, whereas patients with schizophrenia were less distanced from neutral and threatrelated stimuli. Distancing from self-images was mostly associated with depression severity in depressed patients, whereas distancing from hostile and threat-related stimuli with the severity of psychotic and affective symptoms in patients with schizophrenia. Both patient groups used more emotion-oriented than task-oriented and avoidance-oriented coping strategies. Self-distancing among patients with schizophrenia was positively associated with the use of the social diversion coping, implying social support seeking. CONCLUSION: Patients with depression and schizophrenia use different maladaptive emotion- regulation strategies to cope with their symptoms and related distress. Training in stress management might provide these patients with skills for more effective emotion regulation.

This paper describes a study on electrical resistivity under loading of polyaniline (PANI)/graphene nanocomposite powders and compacts. The composites were prepared by an in-situ interfacial dynamic inverse emulsion polymerization technique under sonication of aniline in the presence of graphene sheets in chloroform. During polymerization the graphene nanoplatelets are coated with PANI and are well dispersed both in the polymeric suspension and then in the dried polymer matrix as evidenced by cryogenic transmission electron microscopy (Cryo-TEM) and high resolution scanning microscopy (HrSEM). The presence of graphene nanoplatelets lowers the electrical resistivity of the polyaniline by two orders of magnitude for both the powder and the compact composites as demonstrated by their electrical resistance measurements conducted under loading. The lowest measured electrical resistivity values were 5 Ω·cm for 33% wt. graphene powder and 8 Ω·cm for 41% wt. graphene compacted composites. Cyclic electrical measurements under loading showed a distinct reproducible dependence of the bulk resistivity vs. applied pressure. This repetition is a key component for electro-mechanical sensors. To the authors’ best knowledge, this is the first report on polymerization of aniline in presence of graphene by the in-situ interfacial dynamic inverse emulsion polymerization technique and also the first report on cyclic electrical measurements under pressure of PANI/graphene nanocomposites.
