- MakaleAçık Erişim2016Scopus SJRQ4Ultrasonographic assessment of the shoulder in patients with carpal tunnel syndrome
Mansiz Kaplan, Basak; Yagci, Ilker; Akdeniz Leblebicier, Merve
Objectives: To detect the causes of shoulder pain with shoulder ultrasonography in patients with carpal tunnel syndrome (CTS) and compare the findings of the patients with CTS to healthy controls. Patients and Methods: Patients with CTS and healthy controls were evaluated clinically, electrophysiologically. and ultrasonographically by three masked researchers. Electrophysiological assessment consisted median and ulnar nerve conduction studies (NCS). In ultrasonographic assessment, cross-sectional areas of the median nerve were measured at hamatum hook, psiform bone, radio-ulnar joint levels. Shoulder joint, axial and longitudinal biceps tendon, subscapularis tendon, supraspinatus tendon, infraspinatus tendon, rotator cuff, acromioclavicular joint were evaluated by a standardized protocol. Results: The study was completed with 30 patients with CTS and 30 healthy subjects. The presence of shoulder pain in the last week was 53.3% in the CTS group and 30% in the control group but there was no statistically significant difference between the groups (p=0.16; p>0.05). Subdeltoid bursitis was significantly more common in CTS group when compared to the control group (p=0.03) in ultrasonographic assessment, and there was no significant difference between the two groups for other parameters. Conclusion: Shoulder pain and subdeltoid bursitis were common in patients with CTS however, shoulder pain was not directly related to shoulder problems alone. Central sensitization may play a role for shoulder pain rather than shoulder problems.

Altunisik, Ahmet Can; Günaydin, Murat; Sevim, Baris; Bayraktar, Alemdar; Adanur, Suleyman
Continuous health monitoring and regular condition assessment is of vital importance for engineering structures in general and especially for arch dams. These structures can be exposed to many different loads such as earthquake, blast, wind, ice, and water pressure, which may cause deterioration and loss of structural integrity. Such development may have severe economic consequence and, more importantly, may present a serious risk to public safety. Therefore, the structural behavior of arch dams must be monitored at regular intervals during their service life, although the overall failure rate of these dams is around 1%. Experimental measurements by ambient vibration test methods are among the most commonly preferred inspection techniques for the evaluation of structural performance and safety. The aim of this research is to examine the retrofitting effect on the dynamic properties of a damaged arch dam model, with and without reservoir water, after retrofitting with high-strength structural repair mortar and carbon fiber reinforced polymer composite material. To this end, an arch dam-reservoir-foundation model was built. In the study, ambient vibration tests were carried out for three test-cases to determine changes in dynamic properties, such as natural frequency, mode shape, and damping ratio before and after retrofitting. The three cases were (1)a severely damaged dam with full reservoir (Case-A), (2)a repaired dam with full reservoir (Case-B), and (3)a strengthened dam with full reservoir (Case-C). In addition, all the measurement tests were repeated with an empty reservoir to extract the effect of water. Data for the ambient vibration tests were gathered from the dam body during vibrations by natural excitations. These excitations were provided through small impacts, and the response signals were measured by sensitivity accelerometers placed at the crest points. To obtain the experimental dynamic properties, the enhanced frequency domain decomposition method in the frequency domain was used. Comparisons of experimentally identified dynamic properties for the damaged and the retrofitted dam showed that the retrofitting application affected the structural behavior of the arch dam considerably. It was very effective in restoring the structure's original dynamic properties.

Altunisik, Ahmet Can; Günaydin, Murat; Sevim, Baris; Bayraktar, Alemdar; Adanur, Suleyman
This technical note presents an investigation about the changing of dynamic characteristics of an arch dam model before and after strengthening considering reservoir water. To this end, an arch dam-reservoir-foundation model has been constructed in the laboratory. Ambient vibration tests have been performed on the damaged and strengthened arch dam models for empty and full reservoir to determine the effect of water on the dynamics characteristics. Enhanced frequency domain decomposition method has been used to extract the dynamic characteristics. Finally, the dynamic characteristics obtained from the damaged and strengthened dam models have been compared to with each other. Also, the natural frequencies for damaged and strengthened models are compared to detect the effect of strengthening application on the frequencies. Results indicate that the natural frequencies and damping ratios are changed with the full reservoir. However, mode shapes are not changed. Results also show that the natural frequencies of damaged dam considerably increase after strengthening applications.

Atayan, Yahya; Cagin, Yasir Furkan; Erdogan, Mehmet Ali; Bilgic, Yilmaz; Bestas, Remzi; Harputluoglu, Murat; Seckin, Yuksel
Background. Foreign bodies in the gastrointestinal tract are important morbid and mortal clinical conditions. Particularly, emergency treatment is required for cutting and drilling bodies. The majority of ingested foreign bodies (80-90%) leave gastrointestinal tract without creating problems. In 10-20% of cases, intervention is absolutely required. Less than 1% of cases need surgery. In this paper, we present a schizophrenia patient who swallowed multiple lighters. Case. A 21-year-old male schizophrenic patient who uses psychotic drugs presented to the emergency department with the complaints of abdominal pain, severe vomiting, and inability to swallow for a week. His physical examination revealed epigastric tenderness. A plain radiograph of the abdomen revealed multiple tiny metallic densities. Gastroscopy was performed. The lighters were not allowing the passage, and some of them had penetrated the gastric mucosa, and bezoars were observed. One lighter was extracted with the help of the polypectomy snare. Other lighters as a bezoar were removed by surgery. Conclusion. Excessive vomiting of swallowed foreign bodies in the etiology of psychotic patients should be kept in mind. Endoscopic therapy can be performed in the early stages in these patients, but in the late stage surgery is inevitable.

Koyuncu, Julide Yalcinkaya; Yilmaz, Rasim; Ünver, Mustafa
We examine the relationship between various indicators of female labor force participation and labor productivity. We test the hypothesis that labor productivity boosts as the female employment increases by exploiting a panel data set including the period 1985 to 2010 and 111 countries and using three labor productivity indicators and three female labor force participation indicators. We identified a positive correlation between female labor force participation indicators and labor productivity. This finding is statistically significant and valid for three different productivity indicators and three different female labor force participation indicators. Thus, the results suggest that female labor force participation increases labor productivity, controlling for other factors that may contribute to labor productivity.

Determination of land ownership and boundaries is one of the most important purposes of the urban and rural land laws. There can be some boundary problems while preparing forestry area of any urban area when there is not consistency between the borders constructed by different state organizations like land cadastre, forest cadastre and forest management and planning teams. This study aims to illustrate these conflicts in forestry applications process of two different areas (Agva and Beykoz) having different characteristics. The study was carried out in Agva and Beykoz districts in the province of Istanbul and focused on the integration in the land and forest cadastral systems. The Beykoz and Agva Forest Planning Units have different characteristics in terms of population (urban and rural) and social impacts. Analyses of the data obtained from the field studies which it was utilized for the investigation of the data obtained from various base maps, were carried out using GIS software. Many inhabitants of the villages in the Agva Planning Unit had migrated from the district. Thus, in accordance with Boundary Law number of 6831 part of 2/B some parcels of villages in Agva were determined to be acting forest and were reassigned as forest land. In Beykoz, however, areas of this nature were few and the destruction of the forests was great. The spatial analysis of the study made it possible to remove discrepancies occurring in the cadastral situation by preparing forest management plans. Consequently, if land cadastre and forest cadastre units carry out work in coordination to determine the cadastral situation, a basis for forest management plans can be established and cadastral problems greatly reduced.

All marketing definitions focus on the same point: customer orientation and the satisfaction of customer needs. Within this framework, although marketing approach in most of studies primarily deal with institutions and enterprises in profit/private sector, it has become crucial for all kind of organizations including non-profit ones. In recent years, many non-profits have grown larger and continue to improve their growth and effectiveness. In this sense, marketing is touchstone of developing non-profits. This part hopes to create a perspective to marketing definition to understand the relevance of marketing to non-profit organizations and how marketing strategies should be adapted to them for success.

İncele - MakaleAçık Erişim2016Scopus SJRQ2Comparison of flow behavior and physicochemical characteristics of low-cholesterol mayonnaises produced with cholesterol-reduced egg yolk
Yüceer, M.; Ilyasoǧlu, H.; Özçelik, B.
Egg yolk is common functional ingredient in food production, mainly in mayonnaise as an emulsifier. Egg yolk cholesterol was removed using β-cyclodextrine, treated with α-Amylase, and low-cholesterol mayonnaise produced. The flow behavior of cholesterol-reduced mayonnaise was investigated at different cholesterol-reduced egg yolk and xanthan gum content. The aim of this study was to evaluate the effects of different formulations at various percentages of egg yolk (EY; 4 and 6 percent by weight) and xanthan gum (XG; 0.5 and 0.7 percent by weight) on flow behavior and physicochemical properties of reduced-fat and low-cholesterol mayonnaise prepared with cholesterol-reduced liquid egg yolk and to obtain suitable model for mayonnaise formulations. The aim of the study was to develop a reduced-fat and lowcholesterol mayonnaise with properties similar to those of typical mayonnaise in the market. For this purpose, four reduced-fat and low-cholesterol mayonnaise formulations were prepared in the laboratory using cholesterol-reduced EY. They were compared with a commercial mayonnaise from a local market as a control sample. According to results, color parameters and flow behaviors of the samples compared with the control sample indicated that the samples had higher values of lightness and yellowness, and presented lower values of yield stress and flow behavior index and higher values of consistency coefficient with respect to the commercial product, except recipe that included 6% of EY and 0.7% of XG, which exhibited similar values to the typical commercial one in the market. The Herschel Bulkley model was employed in order to evaluate the effect of EY and XG ratios on mayonnaise rheological behavior. In general, the results obtained suggest that the recipe with EY (6 wt%) and XG (0.7 wt%) had better rheological characteristics and physicochemical properties those prepared with various formulations, maintaining the reduced-fat and low-cholesterol mayonnaise prepared with β-cyclodextrine-Treated cholesterol-reduced EY. It can be interpreted that the developed product may have potential use in industrial application.

Defatted hazelnut flour (DHF) in different levels (5%, 10% and 15%) of locust bean, guar and xanthan gum were added in rice-based gluten-free formulations to improve rheological properties of dough and baking properties of bread. The rheological characteristics of dough samples were determined by steady flow curves and dynamic tests. The baking properties of breads were evaluated by specific volume, Textural Profile Analysis (TPA) parameters and color values. The rheological measurements showed that all gluten-free dough had pseudoplastic behavior. Specific volume values of breads ranged from 2.20 to 2.83cm3/g. Gum addition enhanced the specific volume of gluten-free breads. Hardness values of gluten-free breads ranged from 1,069.80 to 3,135.88 g and DHF addition of gluten-free formulations caused significant decrease of the hardness values of breads (p < 0.05). DHF addition in gluten-free formulations made bread crumb darker than bread without DHF and gum. DHF addition also increased a and b values of gluten-free bread's crumb.

Dincel, Gungor Cagdas; Atmaca, Hasan Tarik
Toxoplasma gondii (T. gondii) is a protozoan parasite with the potential of causing severe encephalitis among immunocompromised humans and animals. Our previous study showed that T. gondii induces high nitric oxide (NO) production, high glial activation (GFAP) and neurofilament expressions, leading to severe neurodegeneration in toxoplasma encephalitis (TE) in the central nervous system (CNS). The aim of this experimental study was to investigate ADAMTS-13 expression and apoptosis in CNS and to identify whether they have any correlation with toxoplasmosis neuropathology and neurodegeneration. Mice were infected with ME49 strain T. gondii and the levels of ADAMTS-13, caspase 3, caspase 8, caspase 9, TNFR1 and Bcl-xL expressions were examined in brain tissues by immunohistochemistry, during the development and establishment of chronic infections at 10, 30 and 60days post-infection. Results of the study revealed that the levels of ADAMTS-13 (P < 0.005), caspase 3 (P < 0.05), caspase 8 (P < 0.05), caspase 9 (P < 0.005) and TNFR1 (P < 0.05) expressions in the brain markedly increased while Bcl-xL expression decreased (P < 0.005). The most prominent finding from our study was that 10, 30 and 60days post-infection ADAMTS-13 increased significantly and this may play an important role in the regulation and protection of the blood-brain barrier integrity and CNS microenvironment in TE. These results also suggest that T. gondii-mediated apoptosis might play a pivotal role and a different type of role in the mechanism of neurodegeneration and neuropathology in the process of TE. Furthermore, expression of ADAMTS-13 might give an idea of the progress and is critical for diagnosis of this disease. To the best of the authors' knowledge, this is the first report on ADAMTS-13 expression in the CNS of T. gondii-infected mice.

Özbek, Mehmet Ferhat; Yoldash, Mohammad Asif; Tang, Thomas Li-Ping
Research suggests that organizational justice (procedural, distributive, and interactional justice) has important impacts on work-related attitudes and behaviors, such as organizational citizenship behavior (OCB). In this article, we explore the extent to which individualism moderates the relationship between organizational justice and OCB (organizational obedience, participation, and loyalty) among citizens in Kyrgyzstan. We make additional contributions to the literature because we know very little about these constructs in this former Soviet Union country, Kyrgyzstan, an under-researched and under-represented region of the world. Results of our data collected from 402 managers and employees in Kyrgyzstan offer the following new discoveries. All three justice constructs are related to OCB. Individualism moderates only the distributive and interactive justice to OCB relationships. We develop an intricate theory with provocative implications: Procedural justice produces obedience. For “individualists,” interactional justice inspires loyalty and, interestingly, distributive justice “can only buy” participation, but “can’t buy” loyalty. Therefore, for individualists, interactional justice outweighs distributive justice for organizational loyalty. Based on Kyrgyz citizens’ justice, OCB, and individualism, our theory reveals novel insights regarding culture, money attitude, and intrinsic motivation and provides critical and practical implications to the field of business ethics.

An accounting information system (AIS) is a system of collecting, storing, and processing financial and accounting data that is used by decision makers. An accounting information system is generally a computer-based method for tracking accounting activity in conjunction with information technology resources. The purpose of this study is to determine the effects of an accounting information system on the institutionalisation level of enterprises. In this regard, a model has been developed and tested. Five hypotheses were constituted to test the model and a questionnaire was conducted to 150 firms that are operating in small and medium sized enterprises in Trabzon. The structural equation model was used to test the hypotheses. According to findings of the analysis it may be seen that an interdepartmental information system, compliance with an accounting information system, and an accounting information system activity have an effect on the institutionalisation level of enterprises.

Treating wood with impregnating materials in order to improve resistance to burning is a commonly employed safety measure. In this study, chestnut (Castanea sativa Mill.) wood samples were impregnated using either Tanalith-E or Wolmanit-CB according to ASTM-D 1413-76 and surface-treated using water-based or synthetic varnish according to ASTM-D 3023. These samples were used to investigate the combustion characteristics of samples left outdoors for one year as detailed in ASTM-E 160-50. The combustion temperatures of the samples left outdoors were similar upon impregnation with either Tanalith-E or Wolmanit-CB. However, the combustion temperature of the samples treated with synthetic varnish was lower than those that were treated with water-based varnish. The time to collapse and the total duration of combustion of the samples left outdoors were shorter for those impregnated with Wolmanit-CB. Weight loss of the samples left outdoors was higher for those that were impregnated with Tanalith-E and treated with water-based varnish. Gas analysis of the samples that were left outdoors indicated that the O2 content of flue gas from samples that were impregnated with Wolmanit-CB and treated with synthetic varnish was high and the CO content of flue gas from the same samples was low.

Aim of Study: Propolis is a resinous bee product, rich of polyphenolic compounds and flavonoids. It is known that in different geographic zones its chemical composition varies due to the different plant sources. Many biological properties including antimicrobial, antioxidative, anti-inflammatory, antitumoral, antigenotoxic, antimutagenic, cytostatic activities have been ascribed to propolis. These biological effects are predominantly attributed to its content of polyphenols. In this study, we aimed to evaluate the radioprotective effect of ethanolic extract of Turkish propolis. (EETP) against γ-ray-induced DNA damage on fibroblast cells using comet assay for the first time. Materials and Methods: Fibroblast cells were pretreated 15 and 30 min with concentrations of 100, 200 and 300 μg/mL EETP then they were exposed to 3 Gy γ-rays. Amifostine (synthetic aminothiol compound) was used as a positive control. Results: The results showed a significant decrease in γ-ray-induced DNA damage on cells treated with EETP and amifostine when compared to only irradiated cells. (P < 001). Conclusion: It was concluded that EETP prevent γ-ray-induced DNA damage in fibroblast cells and might have radioprotective activity.
