Our open heart surgery experience in factor XII deficiency: a case report

Coskun, Elif | Buyukates, Mustafa


Factor XII deficiency is an important hematological problem which is characterized by isolated prolongation of the activated partial thromboplastin time and presents with thrombosis and thromboembolism tendency rather than expected bleeding diathesis in clinical practice. A 55-year-old male patient who was scheduled for aortic coronary bypass graft surgery had elevated activated partial thromboplastin time (109.4 sec) as a laboratory finding. The patient was diagnosed with factor XII deficiency and operated in our clinic. No thromboembolic event was seen during follow-up. The patient was discharged in the seventh postoperative day u . . .neventfully. Herein, we highlight the importance of this disease due to its rare occurrence and present our treatment strategy applied Daha fazlası Daha az

Previous reports of plant regeneration of natural tetraploid T. pratense L. 'Elci' could be realized only through the apical meristem calli. In order to proceed to the production stage, other regeneration methods need to be tried. Aseptic seedlings were used for the production of somatic embryos through various 2,4-D and kinetin trials. Nonuniform external callus cells with translucent cytoplasm were observed in various developmental stages of somatic embryos. Beneath these cells, there were uniformly aligned, dark-stained embryo cells with dense cytoplasm. Despite the similar developmental stages and cell characteristics of zygotic . . . and somatic embryos, the walls of somatic embryo cells revealed a highly wavy pattern. The nucleus generally contained only one nucleolus, which was spherical, dark stained, and electron-dense. Electron-dense droplets were seen in vacuoles. The cytoplasm consisted of starch-containing amyloplasts, mitochondria, plastids, ribosomes, endoplasmic reticulum, dictyosomes, lipid, and protein bodies. In some of the somatic embryos at the globular and heart stages, vacuole or electron-translucent zones were observed in the nucleolus. Additionally, a few embryo degenerations were recorded during developmental stages of the zygotic embryo. For the first time, the somatic embryos of natural tetraploid T. pratense were produced from hypocotyl (85%), cotyledon (75%), and apical meristem (60%) explants in 0.3 mg/L 2,4-D and 2 mg/L kinetin-containing MS medium. Our study developed an effective and efficient in vitro production method for using natural tetraploid T. pratense in biotechnological studies Daha fazlası Daha az

The impact of the extent and severity of coronary artery disease on fractional flow reserve measurements

Sahan, E. | Sahan, S. | Karamanlioglu, M. | Gul, M. | Kalayci, S. | Boyaci, A. | Dereagzi, F.


OBJECTIVE: Coronary angiography has a limitation to determine the severity of intermediate stenosis (30-70%)(1,2). Fractional flow reserve (FFR) is a method for the assessment of the intermediate stenosis severity(3). The effect of coronary artery disease (CAD) severity on the FFR results is not clear. In this study, we aimed to expose the effect of CAD severity calculated with Syntax and Gensini scores on FFR results. PATIENTS AND METHODS: We scanned patients data (n= 378) who had undergone fractional flow reserve measurements in our center. Patients with acute coronary syndrome in the last month, moderate or severe valvular diseas . . .es, acute heart failure, serious bradycardia, atrial fibrillation/flutter, severe left ventricular hypertrophy or patient with deficient data were excluded. 351 patients were included in the study. Syntax and Gensini scores were calculated and compared with FFR results. Hemodynamically significant result for FFR, ratio 22 had notable more crucial lesions in FFR measurements ( Daha fazlası Daha az

A rare case of coronary thrombectomy

Coskun, Elif | Buyukates, Mustafa


A 59-year-old male patient was admitted to our clinic with the complaint of chest pain. Coronary angiography revealed acute myocardial infarction due to a thrombosis at the right coronary artery. Herein, we report a case undergoing quadruple coronary bypass grafting and revascularization and coronary thrombectomy on right coronary artery due to atherosclerotic heart disease and inferior myocardial infarction.

Ottoman Empire's decantralization process started in 17. century and peaked in 18. century. In this study, it is examined that how ayan who is owner of capital accumulation, use their capital in this period. For this reason, it was elaborated that through which cornerstones have caused creation of institution of ayan and how it is fit that the term of entrepreneur (capitalist) in economic literature for this class. On the other hand it was reached that necessary basic conditions (market and the profit/loss motive) did not occur for the development of an entrepreneurial class. However, ayans are not the only concern as a typical entr . . .epreneur to profit, at the same time they act like power forces who want to increase their political power Daha fazlası Daha az

Determining the Relationship Between Some Personal and Organizational Features with Employee Voice: A Study on Academics

Kulualp, Halime Goktas

Article | 2016 | EGE ACADEMIC REVIEW16 ( 4 ) , pp.745 - 761

One of the aim of this study is to focus on voice which couldn't find research space as much as silence. In this direction, the other aim is to analyze that the effect of internal locus of control on employee voice and job satisfaction affected status from employee voice. For this purpose, a survey has performed on 166 academics at Bulent Ecevit University. According to the survey results, the locus of control has a significant effect on employee voice and employee voice has a significant effect on job satisfaction. These results show that the employees with high locus of control are speaker about work problems than the employees wi . . .th low locus of control. The other result is that employees whose have a speak opportunity at work place are more satisfied from their jobs than the employees whose have not a speak opportunity at work place Daha fazlası Daha az

Thermal Energy Investments in Catalagzi Region (Zonguldak)

Article | 2016 | MARMARA GEOGRAPHICAL REVIEW ( 33 ) , pp.510 - 533

As the most prominent instrument for power in modern world, energy is of a vital importance for the development of countries. Industrial development in Turkey, which is one of the developing countries, undergoes increase in energy demand due to rising levels of life standards and tehcnological developments. This rapid demand growth brings about problems such as external energy dependence and deficit in our country, which disposes of limited energy resources. Approximately half of electricity generation in Turkey is obtained by natural gas. Additionally, natural gas is important as an implement for home heating. According to EMRA (En . . .ergy Market Regulatory Authority) data, nearly 85% of the natural gas has been supplied from 3 countries. Building thermal reactors which working with stone coal and lignite, is considered important in order to reduce the impact of a probable difficulty in energy supply. Catalagzi Region in Zonguldak Province is also one of the areas which glare as investment grade. Two active thermal reactors in Catalagzi Region with installed power of 1690 mW, are producing electricity of 12,5million mW on annual basis. With the inclusion of a third thermal reactor planned for the autumn of 2016, electricity generation grade is expected to reach almost 20 million mW on annual basis with an installed power of 3090 mW. In this study it is aimed to emphasize on the partake of Catalagzi Region within electricity generation in Turkey, and to remark the sustainable energy production as well as measures taken for improving the life quality of locals Daha fazlası Daha az

Amaç: Deneysel flep sağ kalımı çalışmalarında en sık kullanılan flepler, rat dorsumundan kaldırılan cilt flepleridir. Çeşitli ebatlardaki modifiye edilmiş McFarlane flepleri, birçok çalışmada sadece kranial bazlı değil ayrıca kaudal bazlı olarak da kullanılmıştır. Bu şekildeki hem kranial hem de kaudal bazlı flep kullanımı, çalışmalarda kullanılan teknikleri kıyaslamanın önündeki en büyük engeli oluşturmaktadır. Bu soruna açıklık getirmek amacıyla kranial ve kaudal bazlı fleplerin sağ kalım oranını karşılaştıran bir çalışma planladık. Gereç ve Yöntemler: Her biri 10 adet rat içeren kranial ve kaudal bazlı flep gurubu olmak üzere 2 g . . .rup oluşturduk. Her bir ratın dorsumundan 11x3 cm'lik kranial veya kaudal bazlı cilt flepleri kaldırdık ve bunların sağ kalımını araştırdık. Kranial bazlı fleplerin sağ kalım oranlarının kaudal bazlı olanlara oranla istatistiksel olarak anlamlı derecede düşük olduğunu bulduk ( Daha fazlası Daha az
