    Metabolic syndrome and features in children and adolescents diagnosed with mood disorders and psychotic disorders
    Kavurma, C; Kara, H; Yalin Sapmaz, S; Öztürk Kara, D; Önder, A
    Objective: Metabolic syndrome (METS) is described as cluster of risk factors including central obesity, hypertension, low high-density lipoprotein (HDL), hypertriglyceridemia and hyperglycemia. The prevalence of METs has been associated with increased symptom severity and antidepressants utilization in many psychopathologies among adult population. We aimed to evaluate the effect of psychopathologies and antipsychotics in METs development, additionally to determine METs characteristics in children and adolescents diagnosed with bipolar and psychotic disorders. Methods: Thirty children and adolescents aged between 13-20 years old of whom were diagnosed with bipolar mood disorders, schizophrenia, schizoaffective disorder and schizophreniform according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision (DSM-IV-TR) criteria were compared with a 30 healthy children and adolescents in present study. The anthropometric measurements including body weight, height, body mass index (BMI), waist circumference (WC) as well as blood pressure measurements were documented. In addition, total cholesterol, triglyceride (TG), HDL, low-density lipoprotein (LDL) and fasting blood glucose (FBG) levels were measured and METs assessed according to the IDF (International Diabetes Foundation) criteria in participants. Results: Overall the prevalence of METs was 20% (n=12) in our study. Among the METs patients, nine were (27%) in the case group, three were (10%) were in control group. The mean BMI, body weight, WC, serum TG and FBG values of the METs group were found to be statistically higher than the healthy control group. Moreover it was also found that utilization of mood-stabilizing drugs has a statistically significant effect on the development of METs. Conclusion: Psychopathologies and antipsychotic utilization have associated with an increased risk for the development of metabolic disorders and METs in the children and adolescents population. In this respect our findings may provide a new approach with the management of treatment strategies particularly in children and adolescents with high risk of METs.

    The sorption behavior of a nickel-insolubilized humic acid system in a column arrangement
    Gezici, O; Kara, H; Ersöz, M; Abali, Y
    The sorption characteristics of insolttbilized humic acid (IHA) were investigated for Ni (II) in a column arrangement. The sodium form of the IHA (INaA) was used as a solid phase. Column operations were performed with five steps and all of them were monitored continuously by a flowthrough cell-adapted UV-Vis spectrophotometer. Thus, all solid-phase extraction (SPE) steps were visualized by breakthrough curves and analyses progress were evaluated. However, all calculations and evaluations were focused on the atomic absorption spectrophotometric (AAS) analyses of the solutions collected during the stripping steps. There was a high correlation (r(2), 0.972) between peak area and AAS data of stripping steps. The effect of concentration and pH of the loading solution onto sorption of Ni (II) by INaA was investigated. Sorption characteristics were evaluated by using Freundlich, Langmuir, and Dubinin-Radushkevich (D-R) adsorption isotherms, as well as by Scatchard plot analysis. Multilayer sorption was found to be agreeable for Ni (II). From the D-R isotherm the mean free energy of sorption (E) was calculated (6.65 kJ mol(-1)) and attributed to the multilayer sorption. Finally, the sorption characteristic of the INaA-Ni (II) system was compared with that of the INaA-Cu (II) system, and possible separation of two ions in a binary mixture system is discussed.
