    Comparison of the modified polyacrylamide gradient gel electrophoresis and high-performance liquid chromatography methods in determining LDL size
    (WALTER DE GRUYTER GMBH, 2022-01-01) Cihan, Murat; Tsukamoto, Hideko; Serdar, Muhittin; Erbil, M. Kemal
    Objectives In this study, we aimed to compare modified Krauss polyacrylamide gradient gel electrophoresis (PAGGE) and high-performance liquid chromatography (HPLC) methods in classification, quantification, and separation of lipoproteins and determining low-density lipoprotein (LDL) size. Methods Blood specimens were obtained from eighty-seven volunteers. We measured LDL size using the PAGGE method and HPLC method with total cholesterol (TC) and triglyceride (TG) peaks. In the PAGGE method, Coomassie Brilliant Blue (CBB) staining was used instead of Sudan black staining, unlike the original method. The relationship between PAGGE and HPLC methods was evaluated by Pearson correlation test and Passing-Bablok regression analysis. Agreement between them was evaluated by Kappa analysis and Bland-Altman plots. Results Statistically significant correlation was found between the LDL size with PAGGE and HPLC methods under the cholesterol curve (HPLC-TC) (r=0.924, p<0.001). Similarly, there was a statistically significant correlation between PAGGE and HPLC methods under the TG curve (HPLC-TG) (r=0.910, p<0.001). In the PAGGE method, within-day precision was found as 2\% and between-day precision as 3\%. It was determined agreement between HPLC-TC vs. HPLC-TG methods and HPLC-TG vs. PAGGE methods was higher than HPLC-TC vs. PAGGE (Kappa values

    Hybrid synchronous treatment of two separate cardiovascular pathologies: Coronary artery bypass grafting and endovascular aortic replacement
    (BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2018-01-01) Anturk, Cem; Bayrak, Fatih; Okten, Eyup Murat; Erdemli, Ozcan; Karabulut, Hasan
    Coronary artery disease and abdominal aortic aneurysm may frequently be together, particularly in elderly patients. Treatment strategies should be tailored according to the needs and specific properties of each patient. Hybrid synchronous procedures may be a choice of therapy in these patients, as well as staged procedures. Herein, we present the first hybrid synchronous case of Turkey to treat two separate cardiovascular pathologies.
