Evaluation of clinical and demographic characteristics and their association with length of hospital stay in patients admitted to cardiac intensive care unit with the diagnosis of acute heart failure
Sami ?ahin,Umuttan Do?an,Kurtulu? ?zdemir,Hasan G?k
Anadolu Kardiyoloji Dergisi , 2012,
Abstract: Objective: Despite increasing incidence, data regarding clinical and demographic characteristics of patients with acute heart failure (AHF) admitted to cardiac intensive care unit (ICU) are inconclusive. The aim of this study was to assess the presentation characteristics and factors determining the length of hospital stay in this particular patient population.Methods: We conducted a single-center, prospective study involving 150 patients hospitalized to cardiac ICU with the primary diagnosis of AHF. Chi-square and Student t tests were used for the analysis of categorical and continuous variables, respectively. Linear regression analysis (LRA) was used to determine the factors affecting the length of hospital stay. Results: Forty-nine percent of the patients had new-onset AHF and 25% had preserved left ventricular ejection fraction (LVEF). In 25.3% of all patients and 46.6% of the patients with new-onset HF the precipitating factor was acute coronary syndrome. Atrial fibrillation and valvular heart disease as precipitating factors were more common in patients with preserved EF, when compared to low EF group. LRA showed that presence of anemia [β=1.62; 95% CI 0.08-3.15; p=0.039)] and severe mitral regurgitation (β=2.55; 95% CI 0.06-5.05; p=0.045) and systolic blood pressure (β=-0.03; 95% CI -0.06 - -0.002; p=0.039) and blood urea nitrogen (β=0.034; 95% CI 0.006 - 0.06; p=0.016) were the independent predictors of length of stay. Conclusion: Underlying cardiovascular risk factors, comorbidities and precipitating pathologies were diverse and highlighted the inhomogeneous characteristics of AHF syndromes. However, in-hospital mortality was high and initial clinical presentation characteristics were significantly associated with in-hospital outcome.

A Research on the Impacts of Core Employees on the Performances of SME’s  [PDF]
Kurtulu? Y?lmaz Gen?
Sociology Mind (SM) , 2014, DOI: 10.4236/sm.2014.43021
This study includes a research on the impacts of core employees on the perceived performances of Small and Medium Sized Enterprises (SME’s). Employees, who are working at manufacturing department or basic function, were taken as core employees in the frame of the research. This research was conducted at the Middle and Eastern Black Sea region of Turkey; at 60 SME’s. The research was realised on the bases of the resource-based view of the firm; the relation between the characteristics of core employees as rareness, hardness to imitation and the perceived performances of SME’s were given. This study contributes to the literature for its regional focus to the topic and for the presentation of how SME’s perceive organizational performance as dimensional context. The results of the research didn’t support the hypothesis which claims that there is a positive relationship between the expertises of core employees, whose superior characteristics are specific to firms and the organizational performance.
Mechanisms of preventative and therapeutic role of probiotics in different allergic and autoimmune disorders  [PDF]
?ner ?zdemir
Open Journal of Immunology (OJI) , 2013, DOI: 10.4236/oji.2013.33015

The prevalence of allergic and autoimmune diseases has been increasing from the last decades of 20th century. Intestinal microflora contributes to antigen exposure in early life and is one of the most abundant sources of early immune stimulation as well as adaptation. Because allergic and autoimmune responses manifest early in life, there has been obvious interest in the potential benefits of modifying the gastrointestinal flora by using probiotic supplementation. So far, there have been several studies to address the role of probiotics in primary prevention and therapy, with a reported suspicious reduction in the incidence of atopic and autoimmune diseases. Here, our aim is to evaluate the available knowledge of mechanisms of preventative and therapeutic role of probiotics in different allergic and autoimmune disorders. Promising mechanisms of probiotic effects may be categorized as local and systemic effects. Local influences of probiotics potentially include reduction of gut permeability and systemic penetration of antigens, increased local immunoglobulin A production, and alteration of local inflammation or tolerance induction. Some possible systemic effects consist of anti-inflammatory effects mediated by Th17 cells and Toll-like receptors, Th1 skewing of responses to allergens, activation of tolerogenic dendritic cells, in addition to T-regulatory cell production.

Effect of immediate implant placement and loading on soft tissue management  [PDF]
Erdem ?zdemir, Yener Oguz
Open Journal of Stomatology (OJST) , 2013, DOI: 10.4236/ojst.2013.37066

The recent article describes immediate implant placement and loading in the anterior segment. The main aim of this treatment option was to deliver provisional prosthesis to the patient in the same day of surgery, form papilla contours, and eliminate waiting of osseointegration time and the second surgery.

Teachers’ and Students’ Views Toward The Activities of the Primary Science and Technology Curriculum

Necatibey Faculty of Education, Electronic Journal of Science and Mathematics Education , 2011,
Abstract: The aim of this study is to find out teachers’ and students’ views about preparation, application and evaluation of activities in which the Primary Science and Technology Curriculum began to be used since 2004-2005 education year. In the study, qualitative research design was used. The data were gathered through semi-structured interviews conducted with 3 science and technology teachers who work at various primary schools in Trabzon and 9 primary school students. The gathered data were presented by classifying under categories. One of the most important result of the study is that activities are generally applied teacher-centered because of material shortage, lack of time and overcrowded classrooms. It is suggested as the first step for solution of problems that physical conditions in the schools are got better and the teachers are educated in In-Service Teacher Education Program systematically.
Thiol-Disulphide Balance: Could Be a New Marker for Thyroid Cancer?  [PDF]
Ay?e ?zdemir, ?zcan Erel
Journal of Cancer Therapy (JCT) , 2018, DOI: 10.4236/jct.2018.98051
Abstract: Objectives. Cancer is a very widespread disorder known in world wide since long, but its biochemical features remain unclear. Thyroid carcinomas are the most common endocrine cancer and its frequency continues to escalate. There is evidence that the serum concentration of TSH is an unreliant predictor for the diagnosis of thyroid cancer. The formation of the plasma thiol pool from low and large molecular weight proteins suggests that thiol/disulfide balance is important in cancerous cases. The aim of this study was to investigate an oxidative stress marker (thiol/disulphide homeostasis) and IMA (Ischemia modified albumin), Albumin, CEA (Carcinoembryonic antigen), TSH (Thyroid stimulate hormone), thyroxine (T4), free thyroxine (FT4), triiodothyronine (T3) and free triiodothyronine (FT3) in patients with thyroid cancer and compare the results with healthy controls for the first time in literature. Materials-Methods: A total of 43 participants including 23 patients with thyroid cancer and 20 healthy individuals were included in the study. Serum levels of TSH, T4, FT4, T3 and FT
