| 1 | Gastrointestinal bezoars: A retrospective analysis of 34 cases显示文摘AIM: Bezoars (BZ) are the most common foreign bodies of gastrointestinal tract. Clinical manifestations vary depending on the location of BZ from no symptoms to acute abdominal syndrome. When located in small bowel, they frequently cause small bowel obstruction (SBO). We aimed to present our experience by reviewing literature.METHODS: Thirty-four patients with gastrointestinal BZ were presented. The data were collected from hospital records and analyzed retrospectively. Morbidity and mortality rates were statistically analyzed between the subgroups according to SBO and endoscopic or surgical treatment modalities.RESULTS: The 34 patients had phytobezoars (PBZ). Two patients with mental retardation and trichotillomania had trichobezoars (TBZ). More than half of them (55.88%) had previous gastric surgery. Also most of them had small bowel bezoars resulting in obstruction. Surgical and endoscopic morbidity rates were 32.14% and 14.28% respectively.The total morbidity rate of this study was 29.41%. Four patients in surgically treated group died. There was no death in endoscopically treated group. The total and surgical mortality rates were 11.76% and 14.28% respectively. The differences in morbidity and mortality rates between the subgroups were not statistically significant.CONCLUSION: BZ are commonly seen in stomach and small intestine. SBO is the most common complication.When uncomplicated, endoscopic or surgical removal can be applied easily. | Kenan Erzurumlu Zafer Malazgirt Ahmet Bektas Adem Dervisoglu Cafer Polat Gokhan Senyurek Ibrahim Yetim Kayhan Ozkan | 2005 | World Journal of Gastroenterology2005，11，12： | 33 |
| 2 | Lipoma within inverted Meckel’s diverticulum as a cause of recurrent partial intestinal obstruction and hemorrhage: A case report and review of literature显示文摘Lipoma within an inverted Meckel's diverticulum presen- ting with hemorrhage and partial intestinal obstruction is an exceptional clinical entity. We report a case of 47-year-old male with a history of recurrent episodes of partial intestinal obstruction and melena due to a subserosal lipoma located in the base of an inverted Meckel's diverticulum. According to our knowledge, this is the first case of a lipoma within a Meckel's diverticulum giving rise to this clinical scenario without the existence of heterotrophic gastric or pancreatic tissues. | Güldeniz Karadeniz Cakmak Ali Ugur Emre Oge Tascilar Sibel Bekta■ Bulent Hamdi Uan Oktay Irkorucu Kemal Karakaya Yucel Ustundag Mustafa Comert | 2007 | World Journal of Gastroenterology2007，13，7： | 11 |

| 4 | 采用锰矿从水溶液中吸附铅和镉离子(英文)显示文摘采用低成本的本地可得的天然锰矿作为吸附剂,研究吸附工艺从水溶液中脱除铅离子和镉离子。利用伪一级、伪二级动力学和颗粒内扩散模型检验动力学吸附数据,计算和比较这些动力学模型的吸附速率常数,发现用伪二级动力学模型能最佳地描述吸附动力学。将 Langmuir 和 Freundlich 等温吸附模型用来拟合不同温度下的平衡数据,发现实验数据与 Langmuir 模型拟合得更好。采用 Langmuir 等温吸附模型计算出锰矿吸附铅离子和镉离子的最大容量分别为 98 和 6.8 mg/g。计算了热力学参数,如吸附吉布斯自由能的变化、焓变与熵变。结果表明,锰矿作为吸附剂对铅和镉的吸附反应是自发的吸热反应。因此,锰矿作为一种天然的矿物吸附剂,可以替代现有的吸附剂来脱除水溶液中的铅离子和镉离子。 | Aylin SNMEZAY M.SALIM NCEL Nihal BEKTAS | 2012 | Transactions of Nonferrous Metals Society of China2012，22，12： | 6 |
| 5 | Nucleoporin 88 expression in hepatitis B and C virus-related liver diseases显示文摘AIM: To investigate the expression of nucleoporin 88 (Nup88) in hepatitis B virus (HBV) and C virus (HCV)-related liver diseases. METHODS: We generated a new monoclonal Nup88 antibody to investigate the Nup88 protein expression by immunohistochemistry (IHC) in 294 paraffin-embedded liver specimens comprising all stages of hepatocellular carcinogenesis. In addition, in cell culture experiments HBV-positive (HepG2.2.15 and HB611) and HBV-negative (HepG2) hepatoma cell lines were tested for the Nup88 expression by Western-immunoblotting to test data obtained by IHC.RESULTS: Specific Nup88 expression was found in chronic HCV hepatitis and unspecific chronic hepatitis, whereas no or very weak Nup88 expression was detected in normal liver. The Nup88 expression was markedly reduced or missing in mild chronic HBV infection and inversely correlated with HBcAg expression. Irrespective of the HBV- or HCV-status, increasing Nup88 expression was observed in cirrhosis and dysplastic nodules, and Nup88 was highly expressed in hepatocellular carcinomas. The intensity of Nup88 expression significantly increased during carcinogenesis (P < 0.0001) and correlated with dedifferentiation (P < 0.0001). Interestingly, Nup88 protein expression was significantly downregulated in HBV-positive HepG2.2.15 (P < 0.002) and HB611 (P < 0.001) cell lines as compared to HBV-negative HepG2 cells. CONCLUSION: Based on our immunohistochemical data, HBV and HCV are unlikely to influence the expression of Nup88 in cirrhotic and neoplastic liver tissue, but point to an interaction of HBV with the nuclear pore in chronic hepatitis. The expression of Nup88 in nonneoplastic liver tissue might reflect enhanced metabolic activity of the liver tissue. Our data strongly indicate a dichotomous role for Nup88 in non-neoplastic and neoplastic conditions of the liver. | Martina Knoess Anna Kordelia Kurz Olga Goreva Nuran Bektas Kai Breuhahn Magarethe Odenthal Peter Schirmacher Hans Peter Dienes C Thomas Bock Hanswalter Zentgraf Axel zur Hausen | 2006 | World Journal of Gastroenterology2006，12，36： | 4 |

| 7 | Stress analysis of functionally graded rotating discs: analytical and numerical solutions显示文摘This study deals with stress analysis of annular rotating discs made of functionally graded materials(FGMs).Elasticity modulus and density of the discs are assumed to vary radially according to a power law function,but the material is of constant Poisson's ratio.A gradient parameter n is chosen between 0 and 1.0.When n = 0,the disc becomes a homogeneous isotropic material.Tangential and radial stress distributions and displacements on the disc are investigated for various gradient parameters n by means of the diverse elasticity modulus and density by using analytical and numerical solutions.Finally,a homogenous tangential stress distribution and the lowest radial stresses along the radius of a rotating disc are approximately obtained for the gradient parameter n = 1.0 compared with the homogeneous,isotropic case n = 0.This means that a disc made of FGMs has the capability of higher angular rotations compared with the homogeneous isotropic disc. | Hasan Callioglu Numan Behll Bektas Metin Sayer | 2011 | Acta Mechanica Sinica2011，27，6： | 3 |
| 8 | Extraordinary cause of acute gastric dilatation and hepatic portal venous gas: Chronic use of synthetic cannabinoid显示文摘Addiction to synthetic cannabinoids(SCs) is a growing social and health problem worldwide. Chronic use of SCs may cause adverse effects in the gastrointestinal system. We describe a very rare case of acute gastric dilatation(AGD) and hepatic portal venous gas(HPVG),with findings of acute abdomen resulting from chronic use of a SC, Bonzai. AGD and HPVG were detected by computerized tomography examination. Patchy mucosal ischemia was seen in endoscopic examination. Despite the findings of an acute abdomen, a non-surgical approach with nasogastric decompression, antibiotic therapy, and close radiologic and endoscopic followup was preferred in the presented case. Clinical and radiologic findings decreased dramatically on the first day, and endoscopic findings gradually disappeared over 7 d. In conclusion, this case shows that chronic use of a SC may cause AGD and accompanying HPVG,which can be managed non-surgically despite the findings of acute abdomen. | Mert Mahsuni Sevinc Erdem Kinaci Savas Bayrak Aytul Hande Yardimci Ekrem Cakar Hasan Bektas | 2015 | World Journal of Gastroenterology2015，21，37： | 3 |

| 10 | The role of intracellular protein O-glycosylation in cell adhesion and disease显示文摘Post-translational protein modification,including phosphorylation,is generally quick and reversible,facilitating rapid biologic adjustments to altered cellular physiologic demands.In addition to protein phosphorylation,other post-translational modifications have been identified.Intracellular protein O-glycosylation,the addition of the simple sugar O-linked N-acetylglucosamine (O-GlcNAc) to serine/threonine residues,is a relatively recently identified post-translational modification that has added to the complexity by which protein function is regulated.Two intracellular enzymes,O-GlcNAc transferase and O-GlcNAcase,catalyze the addition and removal,respectively,of O-GlcNAc to serine and threonine side-chain hydroxyl groups.Numerous proteins,including enzymes,transcription factors,receptors and structural proteins have been shown to be modified by intracellular O-glycosylation.In this review,the mechanism and relevance of O-GlcNAc protein modification are discussed in the context of cell adhesion and several representative diseases. | Meryem Bektas David S.Rubenstein | 2011 | The Journal of Biomedical Research2011，25，4： | 2 |
