Red Cell Distribution Width and Acute Complications of Diabetes

Context. Red cell distribution width (RDW) has been associated with type 2 diabetes (T2DM), however data in relation to diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar non-ketotic acidosis (HONK) remains unclear. Objective. The aim of this study was to evaluate the association between RDW, MCV, and RDW/MVC values and acute complications in T2DM. Patients and Methods. RDW was measured in 90 T2DM patients (30 DKA, 30 HONK and 30 T2DM without acute complications). Clinical variables were analyzed by One -Way ANOVA, Kruskal-Wallis and Pearson analysis with SPSS software. Diagnostic screening tests and ROC curve analysis determined the cut-off point of MCV,RDW and RDW/MCV values. Results. DKA patients had higher levels of plasma glucose (524.20 +/- 201.43mg/dL, p<0.001), HbA1c (10.73 +/- 2.29%, p<0.001), osmotic pressure (310.32 mosm/L, p<0.001), RDW (14.61 +/- 1.75g/L, p<0.01), and the RDW/MCV ratio (0.17 +/- 0.04%, p<0.01), compared to HONK patients. RDW/MCV cut-off value was 0.15 with 90% sensitivity 50% specifity these values for only MCV were 76.67%-70%, for only RDW were 76.67%-63.33% respectively. The area under curve values for the ability to reflect DKA for RDW and the RDW/MCV ratio were 0.708 and 0.766, respectively (p<0.001). Conclusions. RDW and RDW/MCV ratio were found associated with DKA and valuable in predicting DKA. However these parameters were not valuable in predicting HONK

Effect of Helicobacter pylori infection on deep vein thrombosis seen in patients with Behçet's disease

Objective: To investigate the role of homocysteine metabolism due to Helicobacter pylori infection on the development of deep vein thrombosis (DVT) in patients with Behcet's disease (BD). Design: Prospective clinical study. Setting: Teaching hospital. Subject: Fifty-five patients with BD divided into groups, with DVT and without DVT, 19 healthy individuals and 18 patients with coronary artery disease (CAD) were enrolled into the study. Interventions: Plasma homocysteine and Hp seropositivity were determined. Results: There was significant Hp positivity in all groups (p>0.05). Homocysteine levels were not significantly different for each group except patients with CAD (p>0.05). Conclusion: There was no difference for frequency of Hp infection in all groups. We conclude that Hp does not influence DVT seen in BD via homocysteine metabolism, but the methinnin-loading test would be appropriate for enlighting patients whose fasting plasma homocysteine levels are found to be normal.

Practical review of the place of social networks in our daily life and their effect on today’s youth,

In this study, we practically reviewed the negative effects of social networks on today’s youth which became somewhat indispensable to them. The study was based on the university students attending public and private universities and the high-school students. The number of participants included in the study is 894 individuals in total. The study was completed in an eight month period. Within this period, specific student groups were asked to fill in a survey composed of eighty questions on their own free will and choices. While the survey had two sections, the 60 questions in the first section were prepared in a 5-point Likert scale. In the first section, questions towards the use of social networks were answered. The last 20 questions were demographic which were arranged as multiple-choice questions. The data from the survey were analyzed via the statistical program SPSS 15. The results of the analysis and findings were presented as tables and explanations at the end of the study. This study contributes to the understanding of social status and problems experienced by today’s youth related to the social networking web pages. At the end of the research, we came to the conclusion that social networks had a negative effect on the youth

Inverse Layer Dependence of Friction on Chemically Doped MoS_{2}

We present the results of atomic-force-microscopy-based friction measurements on Re-doped molybdenum disulfide (MoS2). In stark contrast to the seemingly universal observation of decreasing friction with increasing number of layers on two-dimensional (2D) materials, friction on Re-doped MoS2 exhibits an anomalous, i.e. inverse dependency on the number of layers. Raman spectroscopy measurements revealed signatures of Re intercalation, leading to a decoupling between neighboring MoS2 layers and enhanced electron-phonon interactions, thus resulting in increasing friction with increasing number of layers: a new paradigm in the mechanics of 2D materials.Comment: 15 pages incl.

Combined approach of density functional theory and quantum Monte Carlo method to electron correlation in dilute magnetic semiconductors

We present a realistic study for electronic and magnetic properties in dilute magnetic semiconductor (Ga,Mn)As. A multi-orbital Haldane-Anderson model parameterized by density-functional calculations is presented and solved with the Hirsch-Fye quantum Monte Carlo algorithm. Results well reproduce experimental results in the dilute limit. When the chemical potential is located between the top of the valence band and an impurity bound state, a long-range ferromagnetic correlations between the impurities, mediated by antiferromagnetic impurity-host couplings, are drastically developed. We observe an anisotropic character in local density of states at the impurity-bound-state energy, which is consistent with the STM measurements. The presented combined approach thus offers a firm starting point for realistic calculations of the various family of dilute magnetic semiconductors.Comment: 5 pages, 4 figure

7-17 Yaş Arası Farklı Gelişimsel Özellikleri Olan Çocuklara Sahip Ailelerin Stresle Başa Çıkma Yöntemlerinin İncelenmesi

Zihinsel ve bedensel yetersizlik, hiperaktivite ve davranış bozuklukları ve ortopedik ve travmatolojik rahatsızlıklar sadece duruma maruz kalan bireyleri değil onların aile üyelerini de birçok açıdan (ekonomik, sosyal, duygusal vb.) etkilemektedir. Bu durum aile üyelerinde stres faktörünü artırıcı bir unsur olmaktadır. Stres başa çıkılması gereken ciddi bir sorundur. Aksi taktirde ebeveynlerin içinde bulundukları aşırı stres onların daha da yıpranmalarına ve daha ciddi sağlık problemleriyle karşılaşmalarına neden olabilmektedir. Bu bağlamda araştırmada, 7-17 yaş arası özel gereksinime ihtiyacı olan (Zihinsel ve bedensel yetersizlik/hiperaktivite ve davranış bozukluğu, ortopedik ve travmatolojik rahatsızlık tanısı almış) çocukları olan ailelerin psikolojik iyi olma ve başa çıkma yöntemlerinin incelenmesi ve bazı değişkenler açısından (çocuğun yaşı, engel türü, anne babanın cinsiyeti, eğitim düzeyi vb.) farklılaşmaların ortaya koyulması amaçlanmıştır. Katılımcılara ilk bölümünde, Katılımcıların ve çocuklarının demografik ve betimleyici özelliklerinin, ikinci bölümde ise ebeveynlerin başa çıkma yöntemlerinin ele alındığı bir anket uygulanmıştır. Toplanan verilerin analizi kapsamında betimleyici istatistikler ile ebeveynlerin stresle başa çıkma durumlarının bazı değişkenler açısından farklılıklarının tespitine yönelik ANOVA testinden yararlanılmıştır. Araştırma sonunda, ebeveynlerin sosyo-ekonomik, yaş, eğitim ve cinsiyet değişkenlerinin ve çocukların cinsiyet ve yaş değişkenlerinin ebeveynlerin stresle başa çıkma durumlarında etkili olduğu sonucuna ulaşılmıştır

Demographic Features of Turkish Literature Audiences and Applied Analysis of the Factors Affecting Their Reading Preferences,

The purpose of this study is to determine factors affecting reading preferences in parallel with the demographic features of Turkish literature audiences. The study lasted approximately for 7 months. (N=650) individuals attended the study in total. The universe of the study is Turkey while the sample of the study is composed of 8 different provinces. These provinces are İstanbul, Ankara, İzmir, Bursa, Kocaeli, Sakarya, Trabzon and Gaziantep. A questionnaire form whose reliability and validity had been ensured before and which was composed of 5 point Likert scale was used in the study. The questionnaire form was reformed in accordance with the topic of the study, it was subjected to validity and reliability test and it was carried into main practice through taking views of experts. Data acquired from the results of main practice was analyzed by using SPSS 18.0 packet program and the value of 0.924 was acquired as Cronbach’s Alpha co-efficient. This value indicates that the measuring tool used in this study is quite reliable. The questionnaire is composed of two sections. In the first section, there are questions with regard to determine demographic features of the participants while in the second section, there are scaled questions composed of 120 items. 0.05 of significance level was taken into account among variables in terms of relations and differences. Methods such as different statistics anova, factor and hypothesis tests were applied in the analysis. Moreover, 4 different literary works were mentioned in the study so as to determine attitudes and behaviors of the participants towards literary works. Opinions of the participants were demanded about novels such as İntibah (Rebirth), Araba Sevdası (Ambition for Car), Mai ve Siyah (Blue and Black) and Çalıkuşu (The Wren). At the end of the study, it was found out that the participants followed academic publications more frequently, the use of computer and internet had an effect on reading e-book and up-to-date books were read more than those books written in a foreign or ancient language (Ottoman Turkish). Furthermore, it was determined that education and age variables of the participants had an effect on reading habits while gender, age and education variables had an effect in some reading factors
