So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Purpose: To evaluate the association of genetic polymorphisms of angiotensin converting enzyme, factor V, endothelial nitric oxide synthase, and interleukin-6 in a group of patients that have coronary artery disease. Materials and Methods: Patients were assigned into three groups of 20, one being the control and the other two being the study groups 1 and 2. Group 1 consisted of patients less than 40 years of age with severe coronary artery disease. Group 2 consisted of patients older than 70 years of age with severe coronary artery disease. The control group consisted of patients over 70 years of age with normal coronary arteries. Allele frequencies for angiotensin converting enzyme, factor V, endothelial nitric oxide synthase, and interleukin-6 gene polymorphisms were compared. Results: The allele frequencies for angiotensin converting enzyme, endothelial nitric oxide synthase, and interleukin-6 in groups 1 and 2 were not found to be significantly different from those of the control group. Factor V Leiden ‘A’ allele frequency was found to be significantly higher in group 1 when compared with the control. Conclusion: In the present study angiotensin converting enzyme, endothelial nitric oxide synthase, and interleukin-6 gene polymorphisms were not associated with coronary artery disease in young or elderly patients. However, in the younger group, Factor V Leiden ‘A’ allele frequency was significantly higher than that in the control group. Thus, prothrombotic risk factors might be considered an etiological factor for coronary artery disease in younger patients. Key words: Genetic Polymorphism, Angiotensin Converting Enzyme, Endothelial Nitric Oxide Synthase, Interleukin-6, Factor V CİDDİ ATEROSKLEROZU BULUNAN FARKLI YAS GRUPLARINA AİT HASTALARDA GÖRÜLEN GEN POLİMORFIZMLERİ- NİN KARSILASTIRILMASI Amaç: Bu çalısma, koroner arter hastalığı bulunan bir grup hastada anjiyotensin dönüstürücü enzim, faktör V, endotelyal nitrik oksit sentaz ve interlökin-6 genetik polimorfizmlerinin birlikteliğini değerlendirmektedir. Gereç ve Yöntem : Hastalar, biri kontrol ve diğer ikisi çalısma grubu 1 ve çalısma grubu 2 olarak, 20’ser kisiden olusan 3 gruba ayrıldılar. Grup 1’e ait hastalar, 40 yasın altında ve ciddi koroner arter hastalığı bulunan hastalardan olustu. Grup 2’ye ait hastalar, 70 yasın üstünde ve ciddi koroner arter hastalığı olan kisilerden olustu. Kontrol grubundaki hastalar, 70 yasın üzerinde ve normal koroner arterlere sahip olan kisilerden olustu. Gruplar arasında anjiyotensin dönüstürücü enzim, faktör V, endotelyal nitrik oksit sentaz ve interlökin-6 gen polimorfizmlerine ait allel sıklıkları karsılastırıldı. Bulgular: Grup 1 ve Grup 2’deki hastalarda tespit edilen, anjiyotensin dönüstürücü enzim, faktör V, endotelyal nitrik oksit sentaz ve interlökin-6 gen polimorfizmlerine ait allel sıklıkları kontrol grubundaki deneklerden elde edilen allel sıklıklarından anlamlı derecede farklı bulunmadı. Faktör V Leiden “A” allel sıklığı, Grup 1’e ait hastalarda, kontrol grubuna ait hastalardan anlamlı olarak daha yüksek sıklıkta bulundu. Sonuç: Bu çalısmada gerek genç gerekse yaslı kisilerde, anjiyotensin dönüstürücü enzim, faktör V, endotelyal nitrik oksit sentaz ve interlökin-6 genetik polimorfizmleri, koroner arter hastalığı ile bağlantılı bulunmadı. Ancak genç hastalarda, faktör V Leiden “A” allel sıklığı kontrol grubuna ait hastalardan anlamlı olarak daha yüksekti. Bu nedenle, gençlerde görülen koroner arter hastalıklarında protrombotik risk faktörlerinin etiyolojide rol aldıkları düsünülebilir. Anahtar Kelimeler: Genetik Polimorfizm, Anjiyotensin Dönüstürücü Enzim, Endotelyal Nitrik Oksit Sentaz Ve İnterlökin-6, Faktör V
