Publication Open Access Ovaries are more vulnerable than hepatocytes for insulin resistance and hyperinsulinemia(2016-01-01) GULTEPE, Ilhami; Basaranoglu, METİN; SULEYMANOGLU, Yaser; Basaranoglu, GÖKÇEN; BEYAZIT, Fatma; BAŞARANOĞLU, METİN; BAŞARANOĞLU, GÖKÇENBackground/Aims: Non-alcoholic fatty liver disease (NAFLD) and polycystic ovary syndrome (PCOS) are common metabolic disorders. We aimed to evaluate the underlying mechanisms in the development of NAFLD and PCOS.Publication Open Access Role of Discipline and Educational Method on Vocational High School Students- Success in an Anesthesia Course(2015-04-01) Basaranoglu, GÖKÇEN; Basaranoglu, METİN; BAŞARANOĞLU, GÖKÇEN; BAŞARANOĞLU, METİNObjective: The goal of this study is to reveal the relationship between discipline and teaching method and between vocational high school technical students' success in an anesthesia course and levels of following the lessons. Methods: A questionnaire was filled out by first-year technical students in an anesthesia course for situational awareness evaluation at the beginning of the term. Oral presentations were supported by catechetics, reward systems, etc. to ensure active participation. Results: While the students' success rate was 91.9%, the dissatisfaction rate was 4%. The students stated that they were most satisfied (100%) with the rewarding part of the theoretical lessons. Conclusion: Anesthesiology requires discipline for achieving success. Students' course success on anesthesia can be enhanced using a student-centered learning and reward system.Publication Open Access From fatty liver to fibrosis: A tale of -second hit-(2013-02-28) Basaranoglu, METİN; Basaranoglu, GÖKÇEN; Senturk, HAKAN; BAŞARANOĞLU, METİN; BAŞARANOĞLU, GÖKÇEN; ŞENTÜRK, HAKANAlthough much is known about how fat accumulates in the liver, much remains unknown about how this causes sustained hepatocellular injury. The consequences of injury are recognized as nonalcoholic steatohepatitis (NASH) and progressive fibrosis. The accumulation of fat within the hepatocytes sensitizes the liver to injury from a variety of causes and the regenerative capacity of a fatty liver is impaired. An additional stressor is sometimes referred to as a “second hit” in a paradigm that identifies the accumulation of fat as the “first hit”. Possible candidates for the second hit include increased oxidative stress, lipid peroxidation and release of toxic products such as malondialdehyde and 4-hydroxynonenal, decreased antioxidants, adipocytokines, transforming growth factor (TGF)-β, Fas ligand, mitochondrial dysfunction, fatty acid oxidation by CYPs (CYP 2E1, 4A10 and 4A14), and peroxisomes, excess iron, small intestinal bacterial overgrowth, and the generation of gut-derived toxins such as lipopolysaccharide and ethanol. Oxidative stress is one of the most popular proposed mechanisms of hepatocellular injury. Previous studies have specifically observed increased plasma and tissue levels of oxidative stress markers and lipid peroxidation products, with reduced hepatic and plasma levels of antioxidants. There is also some indirect evidence of the benefit of antioxidants such as vitamin E, S-adenosylmethionine, betaine, phlebotomy to remove iron, and N-acetylcysteine in NASH. However, a causal relationship or a pathogenic link between NASH and oxidative stress has not been established so far. A number of sources of increased reactive oxygen species production have been established in NASH that include proinflammatory cytokines such as tumor necrosis factor (TNF)-α, iron overload, overburdened and dysfunctional mitochondria, CYPs, and peroxisomes. Briefly, the pathogenesis of NASH is multifactorial and excess intracellular fatty acids, oxidant stress, ATP depletion, and mitochondrial dysfunction are important causes of hepatocellular injury in the steatotic liver.Publication Open Access Carbohydrate intake and nonalcoholic fatty liver disease: fructose as a weapon of mass destruction(2015-04-01) Basaranoglu, METİN; Basaranoglu, GÖKÇEN; Bugianesi, Elisabetta; BAŞARANOĞLU, METİN; BAŞARANOĞLU, GÖKÇENExcessive accumulation of triglycerides (TG) in liver, in the absence of significant alcohol consumption is nonalcoholic fatty liver disease (NAFLD). NAFLD is a significant risk factor for developing cirrhosis and an independent predictor of cardiovascular disease. High fructose corn syrup (HFCS)-containing beverages were associated with metabolic abnormalities, and contributed to the development of NAFLD in human trials. Ingested carbohydrates are a major stimulus for hepatic de novo lipogenesis (DNL) and are more likely to directly contribute to NAFLD than dietary fat. Substrates used for the synthesis of newly made fatty acids by DNL are primarily glucose, fructose, and amino acids. Epidemiological studies linked HFCS consumption to the severity of fibrosis in patients with NAFLD. New animal studies provided additional evidence on the role of carbohydrate-induced DNL and the gut microbiome in NAFLD. The excessive consumption of HFCS-55 increased endoplasmic reticulum stress, activated the stress-related kinase, caused mitochondrial dysfunction, and increased apoptotic activity in the liver. A link between dietary fructose intake, increased hepatic glucose transporter type-5 (Glut5) (fructose transporter) gene expression and hepatic lipid peroxidation, MyD88, TNF-α levels, gut-derived endotoxemia, toll-like receptor-4, and NAFLD was reported. The lipogenic and proinflammatory effects of fructose appear to be due to transient ATP depletion by its rapid phosphorylation within the cell and from its ability to raise intracellular and serum uric acid levels. However, large prospective studies that evaluated the relationship between fructose and NAFLD were not performed yetPublication Open Access Mallory-Denk Bodies in chronic hepatitis(2011-05-07) Basaranoglu, METİN; TURHAN, Nesrin; Sonsuz, Abdullah; Basaranoglu, GÖKÇEN; BAŞARANOĞLU, METİN; BAŞARANOĞLU, GÖKÇENMallory-Denk Bodies (MDB) are important as investigators, suggesting MDB as an indicator of the histologic severity of chronic hepatitis, causes of which include hepatitis C, primary biliary cirrhosis (PBC), and nonalcoholic fatty liver disease (NAFLD). Matteoni et al scored MDB in patients with NAFLD as none, rare and many, and reported that MDB plays a prominent role in this classification scheme in an earlier classification system. In this study, we evaluated 258 patients with chronic hepatitis due to metabolic, autoimmune and viral etiologies. Liver biopsy samples were evaluated with hematoxylin and eosin, periodic acid-Schiff-diastase, Gordon and Sweet-s reticulin, Masson-s trichrome, and iron stains. Both staging and grading were performed. Additionally, MDB were evaluated and discussed for each disease. We examined patients with nonalcoholic steatohepatitis (NASH; 50 patients), alcoholic hepatitis (10 patients), PBC (50 patients), Wilson disease (WD; 20 patients), hepatitis B (50 patients), hepatitis C (50 patients) and hepatocellular carcinoma (HCC; 30 patients). Frequency of MDB was as follows; NASH: 10 patients with mild in 60% and moderate in 40% and observed in every stage of the disease and frequently seen in zone 3. PBC: 11 patients with mild in 10%, moderate in 70%, and cirrhosis in 20%, and frequently seen in zone 1. WD: 16 patients with moderate and severe in 60% and cirrhosis in 40% and frequently seen in zone 1. Hep B: 3 patients with mild in 66% and severe in 34%. Hep C: 7 patients with mild in 40% and moderate in 60% and observed in every stage. HCC: 3 patients with hep B in 2 patients. We found that there is no relationship between MDB and any form of chronic hepatitis regarding histologic severity such as alcoholic steatohepatitis and NAFLD and variable zone distribution by etiology.

Methods: A questionnaire was filled out by second-year anesthesia nurse students for situational awareness evaluation at the beginning of the term. The questionnaire form consisted of 19 questions and was prepared according to the basic practice on anesthesia course. Certain practical anesthesia procedures were obliged to make a certain minimum number for anesthesia nurse students. At the end of the year, the same questionnaire form was filled out again. Results: At the beginning of the study period, the ratio of students who did not feel were ready for their future professional life was 60%, whereas this ratio decreased to 20% by the end of the study period. Conclusion: Application of mandatory practical procedures for anesthesia nurse students seem to be very important in preparing them for their future professional life.Publication Open Access Retrospective Evaluation of the Anaesthetic Method Used in Caesarean Sections(2015-04-01) Basaranoglu, GÖKÇEN; Basaranoglu, METİN; BAŞARANOĞLU, GÖKÇEN; BAŞARANOĞLU, METİNObjective: The goal of this study was to evaluate the anaesthetic method used in patients who have undergone caesarean section. Methods: The anaesthetic reports that belong to the women who underwent caesarean section between the years 2014 and 2015 were evaluated in terms of the demographic data, anaesthetic methods, and reported complications. Results: Although 299 patients received general anaesthesia, 75 patients received regional anaesthesia during caesarean section. Mortality was not observed in any patient. Conclusion: Although regional anaesthesia is currently being used mostly in many countries for caesarean sections, our patients chose the general anaesthesia. Making the method of anaesthesia depend on patients’ preferences with the exception of some special conditions such as patients’ fear and anesthesiologist’s additional aliments might have a role in this circumstance.Publication Open Access Pathophysiology of insulin resistance and steatosis in patients with chronic viral hepatitis(2011-09-28) Basaranoglu, METİN; Basaranoglu, GÖKÇEN; BAŞARANOĞLU, METİN; BAŞARANOĞLU, GÖKÇENChronic hepatitis due to any cause leads to cirrhosis and end-stage liver disease. A growing body of literature has also shown that fatty liver due to overweight or obesity is a leading cause of cirrhosis. Due to the obesity epidemic, fatty liver is now a significant problem in clinical practice. Steatosis has an impact on the acceleration of liver damage in patients with chronic hepatitis due to other causes. An association between hepatitis C virus (HCV) infection, steatosis and the onset of insulin resistance has been reported. Insulin resistance is one of the leading factors for severe fibrosis in chronic HCV infections. Moreover, hyperinsulinemia has a deleterious effect on the management of chronic HCV. Response to therapy is increased by decreasing insulin resistance by weight loss or the use of thiazoli-denediones or metfornnin. The underlying mechanisms of this complex interaction are not fully understood. A direct cytopathic effect of HCV has been suggested. The genomic structure of HCV (suggesting that some viral sequences are involved in the intracellular accumulation of triglycerides), lipid metabolism, the molecular links between the HCV core protein and lipid droplets (the core protein of HCV and its transcriptional regulatory function which induce a triglyceride accumulation in hepatocytes) and increased neolipogenesis and inhibited fatty acid degradation in mitochondria have been investigated.
