Abstract: Introduction and Aims:This is a prospective study identifying prevalence of Restless Legs Syndrome (RLS) in patients ongoing peritoneal dialysis (PD) due to end stage renal disease (ESRD) and comparing clinical and biochemical characteristics among patients with and without RLS. Methods: Two hundred ESRD patients who received PD at least six months assessed by neurologist and nephrologist with regards to presence of RLS. Also, clinical and biochemical features of these patients are determined. One hundred and forty four patients were excluded from study because they had other secondary causes of RLS except for ESRD. Results: Thirteen of 56 patients (23.2%) had RLS. The use of vitamin B + folic acid supplements was significantly lower in patients with RLS than in those without RLS (69.2% vs 97.7%; p = 0.008). There was no significant difference between patient groups with and without RLS in terms of age, gender, body mass index, cause of ESRD, peritoneal membrane transport characteristic, smoking, consuming alcohol, use of erythropoietin, duration of PD, hemoglobin, serum calcium, serum phosphorus, serum albumin, levels of serum iron, total iron binding capacity, ferritin, folic acid and vitamin B12, transferrin saturation, weekly Kt/V urea value, and amount of residual urine volume (p > 0.05). Conclusion: RLS is more common among PD patients than general population. Although essential cause is not exactly known, use of folic acid and vitamin B complex decrease the RLS prevalence in this particular patient group.

Abstract: Certainly in the formation of dialects in Anatolia, the migration of Oghuz phratries (Kay , K n k, Salur, Av ar v.s) to this region has been the most important factor. The distribution of phratries in the various parts of the region has not been determined yet. To solve and clarify this issue, long term and comprehensive studies are needed to be carried out. Dialects are important sources of the language. A dialect’s specialities which is used in a common area by the local inhabitants may help to answer some guestions about the past. To this end, in this study the language features the texts collected from the villages of Ala ehir, Manisa and these features have been compared with those of K n k phratry. O uz boylar n n (Kay , K n k, Salur, Av ar vs.) Anadolu’ya g ü, üphesiz, b lgede a z tabakalar n n olu mas ndaki en büyük etkendir. Anadolu’nun e itli b lgelerine yerle mi olan bu boylar n da l m tam olarak tespit edilememi tir. Bu sorunu zmek i in, uzun soluklu a z ara t rmalar yapmak gerekir.

Abstract: The aim of this study is to investigate the effect of institutional structure on economic growth. In this study, for this purpose, the effect of institutional structure on economic growth is analyzed econometrically by employing a “Panel Data Analysis” in the sample including Turkey in thirty-six upper middle income countries for the period between the years 2002 and 2005. Analysis results indicate variables which of the indicators institutional structure voice and accountability, political stability, regulatory quality and rule of law have a negative effect on economic growth, and goverment effectiveness and control of corruption have positive effect on economic growth.

Abstract: Using fully reconstructed $B_{s}$ mesons, we measure exclusive branching fractions for the decays $B_s \to D_s^{(*)+}D_s^{(*)-}$. The results are ${\cal B}(B^0_s\ra D^+_s D^-_s)=(0.58\,^{+0.11}_{-0.09}\,\pm 0.13)%$, ${\cal B}(B^0_s\ra D^{*\pm}_s D^{\mp}_s)=(1.8\, \pm 0.2\,\pm 0.4)%$, and ${\cal B}(B^0_s\ra D^{*+}_s D^{*-}_s)=(2.0\,\pm 0.3\,\pm 0.5)%$; the sum is ${\cal B}(B^0_s\ra D^{(*)+}_s D^{(*)-}_s)=(4.3\,\pm 0.4\,\pm 1.0)%$. Assuming these decay modes saturate decays to CP-even final states, the branching fraction determines the relative width difference between the $B_s$ CP-odd and CP-even eigenstates. Taking \cp\ violation to be negligibly small, we obtain $\dgs/\gs = 0.090\,\pm 0.009\,{\rm(stat.)}\,\pm 0.022 \,{\rm (syst.)}$, where $\gs$ is the mean decay width. The results are based on a data sample collected with the Belle detector at the KEKB $e^+ e^-$ collider running at the $\Upsilon(5S)$ resonance with an integrated luminosity of 121.4 fb$^{-1}$.

Abstract: The purpose of this study is to evaluate Better Life Index which is presented as an alternative instrument to measure well-being in terms of Turkey. This index is created by the OECD and calculated by considering housing, income, jobs, community, education, environment, civic engagement, health, life satisfaction, safety, work-life balance. Results of the study show that Turkey has the lowest Better Life Index value among OECD countries.

Abstract: This in vitro study was designed to assess the effects of fentanyl on isolated rabbit thoracic aorta rings contracted with phenylephrine. Methods included contraction of aorta rings with phenylephrine (10–5 M) and recording the changes after increasing concentrations of fentanyl (10–9 M – 10–5 M). Similar experiments were done after incubation with Nω- nitro-L-arginine methyl ester (10–4 M), indomethacin (10-5 M), naloxone (10–5 M), ouabain (10–5 M), TEA (10–4 M) and glibenclamide (10–5 M). It was revealed that, fentanyl causes relaxation in rabbit aorta rings precontracted with phenylephrine. Removal of endothelium significantly reduces the relaxant response to fentanyl. Nitric oxide synthase inhibitor L-NAME, K+ channel blocker glibenclamide and Na+/K+ ATPase inhibitor ouabain inhibits the relaxant effect of fentanyl in endothelium intact aorta rings. These results suggest that fentanyl causes dose dependent vasodilatation in the rabbit aorta via activation of KATP channels and Na+-K+ -ATPase, and nitric oxide released from endothelium.

Abstract: In this paper, survival data analysis is realized by applying Generalized Entropy Optimization Methods (GEOM). It is known that all statistical distributions can be obtained as distribution by choosing corresponding moment functions. However, Generalized Entropy Optimization Distributions (GEOD) in the form of distributions which are obtained on basis of Shannon measure and supplementary optimization with respect to characterizing moment functions, more exactly represent the given statistical data. For this reason, survival data analysis by GEOD acquires a new significance. In this research, the data of the life table for engine failure data (1980) is examined. The performances of GEOD are established by Chi-Square criteria, Root Mean Square Error (RMSE) criteria and Shannon entropy measure, Kullback-Leibler measure. Comparison of GEOD with each other in the different senses shows that along of these distributions (MinMaxEnt)4 is better in the senses of Shannon measure and of Kullback-Leibler measure. It is showed that, (MinMaxEnt)3 ((MaxMaxEnt)4) is more suitable for statistical data among (MinMaxEnt)m,m=1,2,3,4(MaxMaxEnt)m,m=1,2,3,4. Moreover, (MinMaxEnt)3 is better for statistical data than (MaxMaxEnt)4 in the sense of RMSE criteria. According to obtained distribution (MinMaxEnt)3 (MaxMaxEnt)4 estimator of Probability Density Function?f^(t), Cumulative Distribution Functio?F^

Abstract: Objective: To determine the role of high school students in the cycle of bullying, their selfconcept and the effect of family characteristics associated with the bullying. Methods: We conducted a descriptive, comparative and correlational study. The survey data were collected in the largest province of Turkey, Istanbul, with 1670 students in ninth and tenth grades in six (2 regular, 2 occupational and 2 private) high schools, chosen to represent the types of schools affiliated to Ministry of Education. Data were collected through four different data collection tools: Multidimensional Scale of Peer Victimization, Self-Concept Scale Piers-Harris Children’s, Family Assessment Device and a personal information form. Results: According to the Victimization Scale, 17% of students were in the cycle of bullying (5.3% of aggressors, victims of 5.9%, 5.8% both aggressors as victims). The bullying was significantly more common in the mother-father separated group, in the group that had witnessed violence between family members and those who had been treated violently by family members. Bullying was significantly lower in students with healthy families compared with those who do not have healthy families and students with high average score on the selfconcept compared to those with low average score. Conclusions: This study shows the need to implement effective measures to prevent bullying in schools. Based on the results of the study, it should be emphasized that education can be directed to families through programs to prevent bullying. The focus of the implementation can be concentrated on the effect of family relations on students’ behavior. The existing programs of bullying prevention can be directed to increase the level of self-esteem of students with low self-esteem, because they are more likely to become involved in bullying incidents
Dendritic Cell

Dicle Medical Journal , 2005,
Abstract: Dendritic cells, a member of family of antigen presenting cells, are most effective cells in the primary immune response. Dendritic cells originated from dendron, in mean of tree in the Greek, because of their long and elaborate cytoplasmic branching processes. Dendritic cells constitute approximately 0.1 to 1 percent of the blood’s mononuclear cell. Dendritic cells are widely distributed, and specialized for antigen capture and T cell stimulation. In this article, structures and functions of dendritic cells are reviewed.
