Real-time frame buffer implementation based on external memory using FPGA

In this paper, design of a real-time video frame buffer with an external memory interface is proposed. In addition, simulation and implementation processes of the design is described. The mentioned system is able to buffer video signals up to 1920×1080 full-HD resolution at 60 Hz frame rate. The memory interface is designed based on an external SDRAM memory and supports burst read/write operations. Input video resolution, video buffer size on memory and burst size of the memory interface are user defined and can be configured.Publisher's Versio

Coronary Vasospasm After 5-Fluorouracil Therapy: Case Report

Miyokard disfonksiyonu, perikardit, aritmiler ve akut koroner sendromlar 5-Florourasil (5-FU) tedavisinin yan etkileri olarak bildirilmiştir. 43 yaşında erkek hasta 1 saat önce başlayan göğüs ağrısı nedeniyle hastaneye başvurdu. Hastanın kardiyak öyküsü veya herhangi bir kardiyak risk faktörü yoktu. Hasta kolon karsinom tanısıyla 1 gün önce onkoloji bölümünde 5-FU tedavi almış. Anteriyor ve inferiyor derivasyonlarda ST segment yükselmesi mevcuttu. Hasta akut koroner sendrom kabul edilerek medikal tedavi başlandı ve daha sonra acil koroner anjiografi planlandı. Koroner anjiografi normaldi. İntravenöz nitrat tedavi altındayken hastanın göğüs ağrısı geçti ve EKG’deki ST yüksekliği geriledi. Kardiyak enzimler normal sınırlardaydı. Ekokardiyografide segment hareket bozukluğu yoktu. Hasta 5-FU e bağlı vazospastik angina kabul edildi ve ertesi gün taburcu edildi. Sonuç olarak 5-FU tedavi sonrası akut koroner sendrom gelişebilir. Özellikle kardiyak öyküsü olmayan hastalarda, sıklıkla vazospasmla ilişkilidir ve vazodilatör tedaviye iyi cevap vermektedir.Myocardial dysfunction, pericarditis, arrhythmias and acute coronary syndromes (ACS) are reported as advers effect of 5-Fluorouracil (5-FU). A 43 year-old man admitted to hospital with a chest pain one hour. He had no history of cardiac disease, and also had no any cardiovasculer risk factors. The patient had history of colon carcinoma. One day ago, 5-FU was given as chemotherapy regimen at oncology department. There was ST segment elevation on anterior and inferior derivations. He was initially managed as an acute coronary syndrome and emergency coronary angiography was then performed and it was normal. While introvenous nitroglycerin, the chest pain disappeared and ECG elevation regressed. Cardiac markers were within the normal ranges. There was no any wall motion abnormality on echocardiography. He was accepted vasospastic angina according to 5-FU and discharged after one day. Consequently, after 5-FU therapy, acute coronary syndrome may become. Frequently, it is associated with vasospasm especially patients with no cardiac history, and it response to vasodilator therapy well

Real-time video frame differentiator based on DDR3 SDRAM memory interface

In this paper, design of a real-time video frame differentiator based on an external memory interface is proposed. Furthermore, implementation and simulation processes of the design is discussed. The proposed design is capable of differentiating video frames over time, up to full-HD resolution at 60 Hz frame rate. An external SDRAM memory unit is used within the proposed design and drived by a memory interface. In order to improve the flexibility of the architecture, video resolution, video buffer size on memory and burst size of the memory interface are designed to be user defined and configurable.Publisher's Versio

Demo: Real-time video frame differentiator based on external memory interface

Implementation and demonstration processes of a real-time video frame differentiator based on an external memory interface is described in this paper. The video frame differentiation process is successfully implemented on both low cost and high-end FPGA development boards, then demonstrated by using sample videos at 1024x768@60 and 1920x1080@60 resolutions. Input video resolution, video buffer size on memory and burst size of the memory interface can be configured before implementation.Publisher's Versio

Large ascending aortic aneurysm and severe aortic regurgitation in a 7-year-old child with Marfan syndrome and a review of the literature

WOS: 000223919800004PubMed: 15529906A 7-year-old girl was admitted because of dyspnea on exertion and palpitations. Her symptoms had gradually worsened for the last 6 months. She had physical features of the Marfan syndrome. Transthoracic echocardiography showed an ascending aortic aneurysm, severe aortic regurgitation, and mildly dilated left ventricle. Because of marked aortic aneurysm and severe aortic regurgitation, the patient was treated with a beta-blocker and an angiotensin converting enzyme inhibitor. Surgery was refused by her parents. We describe here a child with Marfan syndrome in whom significant dilatation of the ascending aorta and severe aortic regurgitation is encountered and major cardiovascular complications of Marfan syndrome were reviewed

The prevalence of varicocele in Turkish primary school age children in Kahramanmaras

Objectives: The aim of this study was to determinethe prevalence and site of varicocele in children inKahramanmaras, a city in the south of Turkey and has apopulation of 505,950 in 2007.Materials and Methods: A total of 4543 boys (range,7-14 years of age; mean age±SD, 10.53±1.15 years)were included in this study. All children were examined bytwo specialists at their school and fi ndings of the physicalexaminations were recorded. Varicoceles were classifi edas grade 1 palpable during Valsalva maneuver, grade 2palpable without Valsalva maneuver, and grade 3 visiblewithout the need for palpation. Scrotal pain and contact toany physician were also questioned.Results: Students’ mean age was 10.53±1.15 years.Varicocele was detected in 259 (5.70%) of the 4543 boysaged between 7-14 years; the prevalence was 1.08% inthose aged 7-10 years, and 9.72 % at 11-14 years. Thevaricocele was unilateral in 187 (72.2%) of the 256 boys;of these, fi ve was on the right and the others on the leftside. Three children having grade 3 left varicocele de-scribed left scrotal pain and no children with varicocelehad contact to any physician for examination.Conclusion: According to the resuls of present study, theprevalence of varicocele increases with age. In the 7-14years age group, varicocele is often asymptomatic. Ex-amination of the testicles should be a part of the routinephysical examination for the detection of asymptomaticvaricocele, especially during adolescence
