1Endovascular treatment of carotid cavernous sinus fistula: A systematic review显示文摘Carotid cavernous sinus fistulas are abnormal communications between the carotid system and the cavernous sinus. Several classification schemes have described carotid cavernous sinus fistulas according to etiology, hemodynamic features, or the angiographic arterial architecture. Increased pressure within the cavernous sinus appears to be the main factor in pathophysiology. The clinical features are related to size, exact location, and duration of the fistula, adequacy and route of venous drainage and the presence of arterial/venous collaterals. Noninvasive imaging (computed tomography, magnetic resonance, computed tomography angiography, magnetic resonance angiography, Doppler) is often used in the initial workup of a possible carotid cavernous sinus fistulas. Cerebral angiography is the gold standard for the definitive diagnosis, classification, and planning of treatment for these lesions. The endovascular approach has evolved as the mainstay therapy for definitive treatment in situations including clinical emergencies. Conservative treatment, surgery and radiosurgery constitute other management options for these lesions.Bora Korkmazer Burak Kocak Ercan Tureci Civan Islak Naci Kocer Osman Kizilkilics 2013World Journal of Radiology2013,5,4:14
2Resveratrol attenuates oxidative stress and histological alterations induced by liver ischemia/reperfusion in rats显示文摘AIM:To investigate the effects of resveratrol on liver ischemia/reperfusion (I/R) injury in rats. METHODS: A total of 40 male Sprague-Dawley rats weighing 240-290 g were randomized into four groups of ten: (1) controls: data from unmanipulated animals; (2) sham group: rats subjected to the surgical procedure, except for liver I/R, and given saline; (3) I/R group: rats underwent liver ischemia for 45 min followed by reperfusion for 45 min; (4) I-R/Resveratrol group: rats pretreat- ed with resveratrol (10 μmol/L,iv). Liver tissues wweerre obtained to determine antioxidant enzyme levels and for biochemical and histological evaluation. RESULTS: Plasma aminotransferase activities were higher in the I/R group than in the I-R/Resveratrol group. Malondialdehyde levels and the hepatic injury score decreased, while superoxide dismutase, catalase ,and glutathione peroxidase levels increased in group 4 compared to group 3. In group 4, histopathological changes were significantly attenuated in resveratrol-treated livers. CONCLUSION: These results suggest that resveratrol has protective effects against hepatic I/R injury, and is a potential therapeutic drug for ischemia reperfusion-related liver injury.Ercan Gedik Sadullah Girgin Hayrettin Ozturk Basra Deniz Obay Hulya Ozturk Huseyin Buyukbayram 2008World Journal of Gastroenterology2008,14,46:14

4Evaluation of peripapillary retinal nerve fiber layer, macula and ganglion cell thickness in amblyopia using spectral optical coherence tomography显示文摘AIM:To investigate peripapillary retinal nerve fiber layer (RNFL), macula and ganglion cell layer thicknesses (GCC) in amblyopic eyes with spectral domain optical coherence tomography (SD-OCT). METHODS:Thirty six patients with a history of unilateral amblyopia and thirty two children who had emmetropia without amblyopia were included in this study. In this institutional study, 36 eyes of 36 patients with amblyopia (AE), 36 fellow eyes without amblyopia (FE), and 32 eyes of 32 normal subjects (NE) were included. RNFL, GCC and macular thickness measurements were performed with RS-3000 OCT Retina Scan (Nidek Inc CA. USA). RESULTS:The mean global thicknesses of the RNFL were 113.22 ±21.47, 111.57 ±18.25, 109.96 ±11.31μm in the AE, FE, and NE, respectively. There was no statistically significant difference for mean global RNFL thickness among the eyes (P =0.13). The mean thicknesses of the macula were 258.25±18.31, 258.75±19.54, 248.62±10.57μm in the AE, FE and NE, respectively. There was no statistically significant difference for thickness of macula among the eyes (P =0.06). The GCC was investigated into two parts:superior and inferior. The mean thicknesses of superior GCC were 102.57 ±13.32, 103.32 ±10.64, 100.52 ± 5.88μm in the AE, FE, and NE, respectively. The mean thicknesses of inferior GCC were 103.82 ±12.60, 107.82 ± 12.33, 105.86±10.79μm in the AE, FE and NE, respectively. There was no statistically significant difference for thickness of superior and inferior GCC between the eyes (P =0.63, P =0.46). ·CONCLUSION:The macular thicknesses of AE and FE were greater than the NE, although it was not statistically significant. Amblyopia does not seem to have a profound effect on the RNFL, macula and GCC.Penpe Gul Firat Ercan Ozsoy Soner Demire Tongabay Cumurcu Abuzer Gunduz 2013International Journal of Ophthalmology(English edition)2013,6,1:6
5Mg-Al-Si合金腐蚀的对比研究(英文)显示文摘系统研究在相同冷却条件和成分控制条件下,不同Mg-Al-Si合金(AS11,AS21,AS41,AS61和AS91)的腐蚀行为。采用光学显微镜和扫描电子显微镜观察合金的显微组织。采用浸泡实验和动电位极化测试研究合金在3.5%NaCl溶液中的腐蚀行为。结果表明,添加2.0%Al(质量分数)的合金(AS21)抗腐蚀能力提高,而Al含量大于2.0%(AS41,AS61,AS91)时,合金的抗腐蚀能力降低。这是由于生成了β相作为阴极,以及β相和Mg_2Si相的粗化导致合金表面氧化膜的破裂后不连续。Sennur CANDAN Ercan CANDAN 2017Transactions of Nonferrous Metals Society of China2017,27,8:5
6Medical and alternative therapies in urinary tract stone disease显示文摘Nephrolithiasis is a serious problem for both patients and the health system. Recurrence stands out as a significant problem in urinary system stone disease, the prevalence of which is increasing gradually. If recurrence is not prevented, patients may go through recurrent operations due to nephrolithiasis. While classical therapeutic options are available for all stone types, the number of randomized controlled studies and extensive meta-analyses focusing on their efficiency are inadequate. Various alternative therapeutic options to these medical therapies also stand out in recent years. The etiology of urolithiasis is multifactorial and not always related to nutritional factors. Nutrition therapy seems to be useful, either along with pharmacological therapy or as a monotherapy. General nutrition guidelines are useful in promoting public health and developing nutrition plans that reduce the risk or attenuate the effects of diseases affected by nutrition. Nutrition therapy involves the evaluation of a patient's nutritional state and intake, the diagnosis of nutrition risk factors, and the organization and application of a nutrition program. The main target is the reduction or prevention of calculus formation and growth via decreasing lithogenic risk factors and increasing lithogenic inhibitors in urine. This review focuses briefly on classical medical therapy, along with alternative options, related diets, and medical expulsive therapy.Ercan Yuvanc Erdal Yilmaz Devrim Tuglu Ertan Batislam 2015World Journal of Nephrology2015,4,5:3
7Ultrasound biomicroscopic evaluation of anterior segment cysts as a risk factor for ocular hypertension and closure angle glaucoma显示文摘AIM:To investigate the relationship between the ultrasound biomicroscopic(UBM) features of anterior-segment cysts(ASCs) and increased intraocular pressure(IOP) as a risk factor for closed-angle glaucoma(CAG).·METHODS:Totally 24 eyes with recently diagnosed ASCs were divided into two groups.First group with ASC and ocular normotension(n =13),second group with ASC and ocular hypertension(n =11).An ophthalmologic examination,including tonometry,slit-lamp biomicro-scopy(SLBM),gonioscopy,fundoscopy,pentacam,and UBM,was performed.The features of the ASCs were compared with the IOP.·RESULTS:ASCs were accurately diagnosed and delineated in 24 eyes using UBM.IOP was elevated in those ASCs with a secondary aetiology(P =0.027),iridociliary location(P =0.006),deformed shape(P =0.013),increased size(P =0.001) and elongated pupillary aperture(P =0.009).However,the count(P =0.343) of ASCs,anterior chamber depth(ACD;P =0.22) and axial lenght(AL;P =0.31) were not associated with ocular hypertension.Correlations were found between the IOP and ASC size(r =-0.712;P =0.003),anterior chamber angle(ACA;r =-0.985;P <0.001),angle opening area(AOA;r =0.885;P<0.001),angulation of iris(r =-0.776,P <0.001),and affected iris quadrant(r =-0.655,P =0.002).·CONCLUSION:Ocular hypertension in some eyes with ASC might be associated with various mechanisms,including secondary aetiology,iridociliary location,deformed shape,increased size and elongated pupill,which can be determined by UBM.Abdurrahim Dusak Mehmet Baykara Guven Ozkaya Cuneyt Erdogan Hikmet Ozcetin Ercan Tuncel 2013International Journal of Ophthalmology(English edition)2013,6,4:3
8Association of inflammation with atrial fibrillation in hyperthyroidism显示文摘The aim of this studywas to evaluate the relationship between inflammation and development of atrial fibrillation (AF) in patients with hyperthyroidism.Methods A total of 65 patients with newly diagnosed hyperthyroidism, 35 of whom were in sinus rhythm and 30 of whom in AF. Thirty five age- and gender-matched patients in a control group were included in the study. Factors associated with the development of AF were evaluated by multivariate regression analysis. Results Factors associated with AF in multivariate analysis included high sensitivity C reactive protein (HsCRP) [odds ratio (OR): 11.19; 95% confidence interval (95% CI): 1.80–69.53; P = 0.003],free T4 (OR: 8.76; 95% CI: 2.09–36.7; P = 0.003), and left atrial diameter (OR: 1.25; 95% CI: 1.06–1.47; P = 0.008). Conclusions The results of the present study suggest that HsCRP, an indicator of inflammation, free T4 and left atrial diameter are associated with the development AF in patients with hyperthyroidism.Mehmet Ozaydin Ali Kutlucan Yasin Turker Banu Koroglu Akif Arslan Bayram A.

9Tm-doped ZnO nanorods as a TCO for PV applications显示文摘In photovoltaic(PV) devices, a transparent conducting oxide(TCO) film is used as a transparent electrode which permits sun rays to reach to the photoactive semiconducting layers and also to collect the photogenerated electrons. Due to their electrical and optical properties zinc oxide(ZnO) based thin films and nanostructures are considered as an abundant and safer option for TCOs. In this study, undoped and thulium(Tm)-doped ZnO nanorods(NRs) were produced on glass substrates via spin coating and hydrothermal methods. The ZnO samples were described by X-ray diffractometry(XRD). Morphological features of the ZnO samples were investigated with scanning electron microscopy(SEM). It is observed that the all ZnO samples have nanorod shape. The average rods diameter is between 75 and 100 nm. Also,the rods length is found to be between 0.96 and 1.62 μm. Electrical properties of the ZnO samples were performed via four probe method. The conductivity increases with measurement temperature and Tm doping. Optical spectra of the ZnO samples were measured in UV-Vis range and the band gap(E_g) is found to be 3.35 eV.Hakan Colak Ercan Karakose 2018Journal of Rare Earths2018,36,10:3

11One-year experience in the retinopathy of prematurity: frequency and risk factors, short-term results and follow-up显示文摘· AIM: As a result of the increase in premature births and the advances in neonatal intensive care, retinopathy of prematurity (ROP) remains one of the most important causes of childhood blindness worldwide. The main factors in the development of ROP are gestational age, birth weight and oxygen therapy. ROP continues to gain importance due to the increasing survival rates of more immature babies. · METHODS: Between January 2007 and October 2008, 203 premature infants treated at the Neonatal Intensive Care Unit (NNICU) were prospectively enrolled and the relationship between known risk factors and the occurance of ROP was studied. · RESULTS: ROP in various stages developed in 86 cases (42.4%). Statistically significant correlations were found between the development of ROP and birth weight (P < 0.0001) gestational age (P <0.0001), oxygen treatment and its duration (P <0.0001 and P =0.002), mechanical ventilation (MV) and its duration (P =0,0001 and P =0.0001), apnea(P = 0.001), intraventricular hemorrhage (IVH) (P =0.046), sepsis (P =0.0001), use of erythropoietin (EPO) (P =0.003), the number of blood transfusions and frequency (P =0.0001 and P =0.0001), surfactant application (P =0.0001), the presence of patent ductus arteriosus (PDA) (P =0.001) or bronchopu- lmonary dysplasia (BPD) (P =0.0001). No significant correlations were found between the occurance of ROP and maternal pre-eclampsia (P =0.293), multiple pregnancy (P = 0.218), or hyperbilirubinemia (P =0.494). Severity of ROP was related significantly with birth weight (P =0.0001), but no significant correlation between severity of ROP and gestational age was present. · CONCLUSION: Early description and reduction of the risk factors related with the occurance of ROP with the help of routine screening programs may warrant the prevention of visual loss, however early ophthalmic diagnosis and treatment are still mandatory to provide better visual rehabilitation. ·Sariaydin Mehmet Atlihan Fusun Calkavur Sebnem Olukman Ozgur Ercan Gulten Ozturk Arif Taylan Kaya Kilic Fatma Gokaslan Filiz Altinyaprak Derya Malatyali Rana 2011International Journal of Ophthalmology(English edition)2011,4,6:2

16Primary hepatic carcinosarcoma显示文摘BACKGROUND:Primary hepatic carcinosarcoma is a rare malignant tumor containing an intimate mixture of carci- nomatous and sarcomatous elements.Reports on risk factors, epidemiology,and pathogenesis of the tumor as well as the experience in its treatment are limited. METHOD:We present a case of primary carcinosarcoma of the liver in a 69-year-old man who complained of right hypochondrial pain and weight loss for two months. RESULTS:Magnetic resonance imaging revealed a 14×12 cm mass in segments 7-8 and 4 of the liver with vena hepatica invasion.An ultrasonography-guided biopsy showed osteoid tissue without osteoblastic rimming.Vascular structures accompanied the osteoid tissue.The patient underwent surgery after a diagnosis of hemangioma.Intraoperative frozen sections revealed a carcinosarcoma associated with an osteosarcoma and cholangiocellular carcinoma components. CONCLUSIONS:Preoperative diagnosis of this rare primary hepatic malignant tumor may be difficult by biopsy owing to intratumoral heterogeneity.Highly mature areas of the osteosarcomatous component may lead to misdiagnosis of metaplastic bone tissue.Clinicopathologic features of this rare entity are discussed.Mehmet elikbilek Kemal Deniz Edip Torun Tarιk Artιs Ersin zaslan kkes brahim Karahan Tahir Ercan Patιroglu mer zbakιr 2011Hepatobiliary & Pancreatic Diseases International2011,10,1:2
17Mg-Al-Zn合金腐蚀性能的对比研究(英文)显示文摘对比研究各种Mg-Al-Zn合金(AZ21、AZ41、AZ61和AZ91系列,相同冷却条件并控制合金成分)的腐蚀性能。用扫描电镜(SEM)和X射线衍射(XRD)分析合金的显微结构。通过浸泡实验评估其腐蚀行为,将样品浸泡入3.5%Na Cl溶液中,测量其动电位极化曲线。结果表明,当铝含量小于或等于4%时(如AZ41),对耐腐蚀性的影响更显著,而当铝含量更高时,影响程度较低。当铝含量高于4%时,合金的耐腐蚀性能下降,这与生成的β-Mg_(17)Al_(12)金属间化合物的含量和形貌有关,粗大的β金属间化合物会破坏合金表面氧化膜的连续性。Sennur CANDAN Ercan CANDAN 2018Transactions of Nonferrous Metals Society of China2018,28,4:2
18Cerebral magnetic resonance imaging in quiescent Crohn's disease patients with fatigue显示文摘AIM To evaluate brain involvement in quiescent Crohn's disease (CD) patients with fatigue using quantitative magnetic resonance imaging(MRI).METHODS Multiple MRI techniques were used to assess cerebral changes in 20 quiescent CD patients with fatigue(defined with at least 6 points out of an 11-point numeric rating scale compared with 17 healthy age and gender matched controls without fatigue. Furthermore, mental status was assessed by cognitive functioning, based on the neuropsychological inventory including the different domains global cognitive functioning, memory and executive functioning and in addition mood and quality of life scores. Cognitive functioning and mood status were correlated with MRI findings in the both study groups.RESULTS Reduced glutamate + glutamine (Glx = Glu + Gln) concentrations (P = 0.02) and ratios to total creatine(P = 0.02) were found in CD patients compared with controls. Significant increased Cerebral Blood Flow(P = 0.05) was found in CD patients (53.08 ± 6.14 mL/100 g/min) compared with controls (47.60 ± 8.62 mL/100 g/min). CD patients encountered significantly more depressive symptoms (P < 0.001). Cognitive functioning scores related to memory (P = 0.007) and executive functioning (P = 0.02) were lower in CD patients and both scores showed correlation with depression and anxiety. No correlation was found subcortical volumes between CD patients and controls in the T1-weighted analysis. In addition, no correlation was found between mental status and MRI findings.CONCLUSION This work shows evidence for perfusion, neurochemical and mental differences in the brain of CD patients with fatigue compared with healthy controls.Sanne van Erp Ece Ercan Perla Breedveld Lianne Brakenhoff Eidrees Ghariq Sophie Schmid Matthias van Osch Mark van Buchem Bart Emmer Jeroen van der Grond Ron Wolterbeek Daniel Hommes Herma Fidder Nic van der Wee Tom Huizinga Désirée van der Heijde Huub Middelkoop Itamar Ronen Andrea van der Meulen-de Jong 2017World Journal of Gastroenterology2017,23,6:2
