    One of the main issues in kidney transplantation is the optimal functional preservation of the organ until its transplantation into the appropriate recipient. Despite intensive efforts, the functional preservation period remains limited to hours. During this time, as a result of cellular injury, various proteins, peptides, and other molecules are released by the organ into the preservation medium. In this study, we used proteomic techniques to analyze the protein profiles of preservation solutions in which organs had been preserved prior to their transplantation. Samples were obtained from the preservation solutions of 25 deceased donor kidneys scheduled for transplantation. The protein profiles of the solutions were analyzed using 2D gel electrophoresis/MALDI-TOF and LC-MS/MS. We identified and quantified 206 proteins and peptides belonging to 139 different groups. Of these, 111 proteins groups were belonging to kidney tissues. This study used proteomic techniques to analyze the protein profiles of organ preservation solutions. These findings will contribute to the development of improved preservation solutions to effectively protect organs for transplantation.

    Cystic pancreatic lymphangioma
    (PAGEPRESS PUBL, 2012-01-01) Gures, Nazim; Gurluler, Ercument; Alim, Altan; Berber, Ibrahim; Gurkan, Alihan
    Lymphangioma of the pancreas is a rare benign tumor of lymphatic origin. Retroperitoneal lymphangiomas account for 1\% of all lymphangiomas. Herein, we report a case of cystic pancreatic lymphangioma diagnosed in 34 year-old female patient who was hospitalized for a slight pain in the epigastrium and vomiting. Radiological imaging revealed a large multiloculated cystic abdominal mass with enhancing septations involving the upper retroperitoneum. During the laparoscopic surgery, a well circumscribed polycystic tumor was completely excised preserving the pancreatic duct. The patient made a complete recovery and is disease-free 12 months postoperatively.

    Cofilin-1 as a potential biomarker to evaluate acute kidney injury
    (WALTER DE GRUYTER GMBH, 2019-01-01) Coskun, Abdurrahman; Ucal, Yasemin; Berber, Ibrahim; Cakir, Ulkem; Serteser, Mustafa; Moldur, Derya Emel; Derelioglu, Ecenur Izzete; Yozgatli, Tahir Koray; Ozpinar, Aysel; Unsal, Ibrahim
    Acute kidney injury (AKI) is a worldwide health problem and defined by rapid loss of excretory function of the kidney with the accumulation of metabolic end products. For effective treatment and prevent complications the early diagnosis of AKI is crucial. The current analytes used to diagnose AKI are not adequately sensitive and specific and therefore clinicians need new biomarkers. One of the new promising biomarker candidates of renal injury is cofilin-1. Previously, in our laboratory we isolated cofilin-1 in kidney preservation solution prior to transplantation and attempted to measure serum cofilin-1 in renal transplanted patients. However, cofilin-1 was not accurately measured in serum samples due to the methodological issues. In this mini-review, we summarized the current knowledge and concepts both in the literature and our experiences with cofilin-1 as a potential biomarker for the diagnosis and management of AKI.
