| 1 | Microbial profile and antibiotic sensitivity pattern in bile cultures from endoscopic retrograde cholangiography patients显示文摘AIM:To identify the frequency of bacterial growth,the most commonly grown bacteria and their antibiotic susceptibility,and risk factors for bacterial colonization in bile collected from patients with different biliary diseases.METHODS:This prospective study was conducted between April 2010 and August 2011.Patients with various biliary disorders were included.Bile was aspirated by placing a single-use,5F,standard sphincterotome catheter into the bile duct before the injection of contrast agent during endoscopic retrograde cholangiopancreaticography (ERCP).Bile specimens were transported to the microbiology laboratory in blood culture bottles within an anaerobic transport system.Bacteria were cultured and identified according to the standard protocol used in our clinical microbiology laboratory.The susceptibilities of the organisms recovered were identified using antimicrobial disks,chosen according to the initial gram stain of the positive cultures.RESULTS:Ninety-one patients (27% male,mean age 53.7 ± 17.5 years,range:17-86 years) were included in the study.The main indication for ERCP was benign biliary disease in 79 patients and malignant disease in 12 patients.The bile culture was positive for bacterial growth in 46 out of 91 (50.5%) patients.The most frequently encountered organisms were Gram-negative bacteria including Escherichia coli (28.2%),Pseudomonas (17.3%) and Stenotrophomonas maltophilia (15.2%).There were no significant differences between patients with malignant and benign disease (58% vs 49%,P = 0.474),patients with acute cholangitis and without acute cholangitis (52.9% vs 50%,P = 0.827),patients who were empirically administered antibiotics before intervention and not administered (51.4% vs 60.7%,P = 0.384),with regard to the bacteriobilia.We observed a large covering spectrum or low resistance to meropenem,amikacin and imipenem.CONCLUSION:We did not find a significant risk factor for bacteriobilia in patients with biliary obstruction.A bile sample for microbiological analysis may become a valuable diagnostic tool as it leads to more accurate selection of antibiotics for the treatment of cholangitis. | Muhsin Kaya Remzi Bestas Fatma Bacalan Ferhat Bacaksz Esma Gülsun Arslan Mehmet Ali Kaplan | 2012 | World Journal of Gastroenterology2012，18，27： | 13 |
| 2 | 以天然沥青岩为原料制备高压缩强度的泡沫炭(英文)显示文摘以安纳托利亚东南部的天然沥青岩为原料制备泡沫炭。所制泡沫炭的平均孔径和密度分别为150μm和800 kg/m3。主要研究了压力、温度、泄压时间及在最高温度时的停留时间对泡沫形成的影响,同时还评价了炭化过程对泡沫结构的影响。主要研究了压力、温度、泄压时间及在最高温度时的停留时间对泡沫炭进行了表征,并进行了密度及抗压强度分析。结果表明,1 323 K炭化后,泡沫炭压缩强度由10 MPa增加到18.7 MPa。沥青的灰分含量(41.76%)对泡沫炭的密度和压缩强度起重要作用。 | Deniz Baran Mehmet Ferhat Yardim Hüsnü Atakül Ekrem Ekinci | 2013 | 新型炭材料2013，28，2： | 4 |
| 3 | Classification of pepper seeds using machine vision based on neural network显示文摘Pepper is widely planted and used all over the world as fresh vegetable and spice.Genetic and morphological information of pepper are stored through seeds.Determination of seed variety is crucial for correctly identifying genetic materials.Pepper varieties cannot be easily classified even by an expert eye due to the very small size of seeds and visual similarities.Hence,more advanced technologies are required to determine the variety of a pepper seed.A classification method was proposed to discriminate pepper seed based on neural networks and computer vision.Image acquisition was conducted using an office scanner at a resolution of 1200 dpi.Image features representing color,shape,and texture were extracted and used to classify pepper seeds.By calculating features from different color components,a feature database was constructed.Effective features were selected using sequential feature selection with different criterion functions.As a result of the feature selection procedure,the number of the features was significantly reduced from 257 to 10.Cross validation rules were applied to obtain a reliable classification model by preventing overfitting.Different numbers of neurons in the hidden layer and various training algorithms were investigated to determine the best multilayer perceptron model.The best classification performance was obtained using 30 neurons in the hidden layer of the network.With this network,an accuracy rate of 84.94%was achieved using the sequential feature selection and the training algorithm of resilient back propagation in classifying eight pepper seed varieties. | Ferhat Kurtulmuş İlknur Alibaş Ismail Kavdir | 2016 | International Journal of Agricultural and Biological Engineering2016，9，1： | 4 |
