| 1 | Endoscopic submucosal dissection for premalignant lesions and noninvasive early gastrointestinal cancers显示文摘AIM: To investigate the indication, feasibility, safety, and clinical utility of endoscopic submucosal dissection (ESD) in the management of various gastrointestinal pathologies. METHODS: The medical records of 60 consecutive patients (34 female, 26 male) who underwent ESD at the gastroenterology department of Kocaeli University from 2006-2010 were examined. Patients selected for ESDhad premalignant lesions or non-invasive early cancers of the gastrointestinal tract and had endoscopic and histological diagnoses. Early cancers were considered to be confined to the submucosa, with no lymph node involvement by means of computed tomography and endosonography. RESULTS: Sixty ESD procedures were performed. The indications were epithelial lesions (n = 39) (33/39 adenoma with high grade dysplasia, 6/39 adenoma with low grade dysplasia), neuroendocrine tumor (n = 7), cancer (n = 7) (5/7 early colorectal cancer, 2/7 early gastric cancer), granular cell tumor (n = 3), gastrointestinal stromal tumor (n = 2), and leiomyoma (n = 2). En bloc and piecemeal resection rates were 91.6% (55/60) and 8.3% (5/60), respectively. Complete and incomplete resection rates were 96.6% (58/60) and 3.3% (2/60), respectively. Complications were major bleeding [n = 3 (5%)] and perforations [n = 5 (8.3%)] (4 colon, 1 stomach). Two patients with colonic perforations and two patients with submucosal lymphatic and microvasculature invasion (1 gastric carcinoid tumor, 1 colonic adenocarcinoma) were referred to surgery. During a mean follow-up of 12 mo, 1 patient with adenoma with high grade dysplasia underwent a second ESD procedure to resect a local recurrence. CONCLUSION: ESD is a feasible and safe method for treatment of premalignant lesions and early malignant gastrointestinal epithelial and subepithelial lesions. Successful en bloc and complete resection of lesions yield high cure rates with low recurrence. | Sadettin Hulagu Omer Senturk Cem Aygun Orhan Kocaman Altay Celebi Tolga Konduk Deniz Koc Goktug Sirin Ugur Korkmaz Ali Erkan Duman Neslihan Bozkurt Gokhan Dindar Tan Attila Yesim Gurbuz Orhan TarcinDivision of Gastroenterology Derince State Hospital Kocaeli 41900 Turkey Cem Kalayci | 2011 | World Journal of Gastroenterology2011，17，13： | 23 |

| 3 | Resveratrol 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 | 2008 | World Journal of Gastroenterology2008，14，46： | 14 |
| 4 | Design of task-specific optical systems using broadband diffractive neural networks显示文摘Deep learning has been transformative in many fields,motivating the emergence of various optical computing architectures.Diffractive optical network is a recently introduced optical computing framework that merges wave optics with deep-learning methods to design optical neural networks.Diffraction-based all-optical object recognition systems,designed through this framework and fabricated by 3D printing,have been reported to recognize handwritten digits and fashion products,demonstrating all-optical inference and generalization to sub-classes of data.These previous diffractive approaches employed monochromatic coherent light as the illumination source.Here,we report a broadband diffractive optical neural network design that simultaneously processes a continuum of wavelengths generated by a temporally incoherent broadband source to all-optically perform a specific task learned using deep learning.We experimentally validated the success of this broadband diffractive neural network architecture by designing,fabricating and testing seven different multi-layer,diffractive optical systems that transform the optical wavefront generated by a broadband THz pulse to realize(1)a series of tuneable,single-passband and dual-passband spectral filters and(2)spatially controlled wavelength de-multiplexing.Merging the native or engineered dispersion of various material systems with a deep-learning-based design strategy,broadband diffractive neural networks help us engineer the light–matter interaction in 3D,diverging from intuitive and analytical design methods to create taskspecific optical components that can all-optically perform deterministic tasks or statistical inference for optical machine learning. | Yi Luo Deniz Mengu Nezih T.Yardimci Yair Rivenson Muhammed Veli Mona Jarrahi Aydogan Ozcan | 2019 | Light(Science & Applications)2019，8，1： | 9 |
| 5 | Tuberculous peritonitis in children:Report of nine patients and review of the literature显示文摘AIM:To present our experience with tuberculous peritonitis treated in our hospital from 2002-2007. METHODS: We reviewed the medical records of 9 children with tuberculous peritonitis. RESULTS: Nine patients (5 boys, 4 girls) of mean age 14.2 years were diagnosed with peritoneal tuberculosis. All patients presented with abdominal distention. Abdominal pain was seen in 55.5% and fever in 44.4% of the patients. Four cases had coexisting pleural effusion and two had pulmonary tuberculosis with parenchymal consolidation. Ultrasonography found ascites with septation in 7 patients. Two patients had only ascites without septation. Ascitic fluid analysis of 8 patients yielded serum-ascite albumin gradients of less than 1.1 gr/dL. Laparoscopy and laparotomy showed that whitish tuberculi were the most common appearance. Adhesions were also seen in three cases. The diagnosis of peritoneal tuberculosis was confirmed histo-pathologically in 7 patients and microbiologically in two. Two patients had been diagnosed by ascitic fluid diagnostic features and a positive response to antituberculous treatment. All patients completed the antituberculous therapy without any complications. CONCLUSION: Tuberculous peritonitis has to be clinically suspected in all patients with slowly progressive abdominal distension, particularly when it is accompanied by fever and pain. Laparoscopy and peritoneal biopsy are still the most reliable, quick and safe methods for the diagnosis of tuberculous peritonitis. | Gnül Dinler Gülnar Sensoy Deniz Helek Ayhan Gazi Kalayc■ | 2008 | World Journal of Gastroenterology2008，14，47： | 8 |
| 6 | Relationship between intestinal microbiota and colorectal cancer显示文摘The human gastrointestinal tract hosts a complexand vast microbial community with up to 1011-1012 microorganisms colonizing the colon. The gut microbiota has a serious effect on homeostasis and pathogenesis through a number of mechanisms. In recent years, the relationship between the intestinal microbiota and sporadic colorectal cancer has attracted much scientific interest. Mechanisms underlying colonic carcinogenesis include the conversion of procarcinogenic diet-related factors to carcinogens and the stimulation of procarcinogenic signaling pathways in luminal epithelial cells. Understanding each of these mechanisms will facilitate future studies, leading to the development of novel strategies for the diagnosis, treatment, and prevention of colorectal cancer. In this review, we discuss the relationship between colorectal cancer and the intestinal microbiota. | Gokhan Cipe Ufuk Oguz Idiz Deniz Firat Huseyin Bektasoglu | 2015 | World Journal of Gastrointestinal Oncology2015，7，10： | 7 |
| 7 | Clinicopathological features and outcomes of patients with gastric cancer:A single-center experience显示文摘AIM:To evaluate the location,histopathology,stages,and treatment of gastric cancer and to conduct survival analysis on prognostic factors.METHODS:Patients diagnosed with of stomach cancer in our clinic between 2000 and 2011,with follow-up or a treatment decision,were evaluated retrospectively.They were followed up by no treatment,adjuvant therapy,or metastatic therapy.We excluded from the study any patients whose laboratory records lacked the operating parameters.The type of surgery in patients diagnosed with gastric cancer was total gastrectomy,subtotal gastrectomy or palliative surgery.Patients with indications for adjuvant treatment were treated with adjuvant and/or radio-chemotherapy.Prognostic evaluation was made based on the parameters of the patient,tumor and treatment.RESULTS:In this study,outpatient clinic records of patients with gastric cancer diagnosis were analyzed retrospectively.A total of 796 patients were evaluated(552male,244 female).The median age was 58 years(22-90 years).The median follow-up period was 12 mo(1-276 mo),and median survival time was 12 mo(11.5-12.4 mo).Increased T stage and N stage resulted in a decrease in survival.Other prognostic factors related to the disease were positive surgical margins,lymphovascular invasion,perineural invasion,cardio-esophageal settlement,and the levels of tumor markers in metastatic disease.No prognostic significance of the patient's age,sex or tumor histopathology was detected.CONCLUSION:The prognostic factors identified in all groups and the proposed treatments according to stage should be applied,and innovations in the new targeted therapies should be followed. | Fatih Selcukbiricik Evin Buyukunal Deniz Tural Mustafa Ozguroglu Fuat Demirelli Suheyla Serdengecti | 2013 | World Journal of Gastroenterology2013，19，14： | 7 |
| 8 | Variation of vertical and horizontal drilling rates depending on some rock properties in the marble quarries显示文摘The main objective of this study is to determine the rates of vertically and horizontally oriented drilling processes in marble quarries and to observe the factors affecting the drilling rates in terms of physical and mechanical properties of the rocks. In situ drilling tests were performed in different marble quarries with different marble types and drilling times and penetration rates for a series of successive depthincrements were trying to be determined under vertically and horizontally oriented conditions. In order to understand the relation between the parameters that are investigated within the scope of this research, uniaxial compressive strength, Brazilian tensile strength, impact strength, Bohme abrasion strength, P-wave velocity, porosity, unit volume weight, Schmidt hardness index and brittleness index values were correlated with the drilling rates. It was noticed that the porosity and unit volume weight could be taken as the key parameters among them for obtaining meaningful correlation with drilling performance. It was also observed that the physical and mechanical rock properties are more relevant in vertical drilling than horizontal drilling. | Servet Demirdag Nazmi Sengun Ibrahim Ugur Tamer Efe Deniz Akbay Rasit Altindag | 2014 | International Journal of Mining Science and Technology2014，24，2： | 7 |
| 9 | Treatment of ocular rosacea: comparative study of topical cyclosporine and oral doxycycline显示文摘AIM: To compare the effectiveness of topical cyclosporine A emulsion with that of oral doxycycline for rosacea associated ocular changes and dry eye complaints.METHODS: One hundred and ten patients with rosacea were screened. Thirty-eight patients having rosacea associated eyelid and ocular surface changes and dry eye complaints were included in the study. Patients were randomly divided into two groups: nineteen patients were given topical cyclosporine twice daily and nineteen patients were given oral doxycycline 100 mg twice daily for the first month and once daily for the following two months. Symptom and sign scores, ocular surface disease index questionnarie and tear function tests were evaluated at baseline and monthly for 3mo. Three months after results were compared with that of baseline.RESULTS: Mean values of symptom, eyelid sign and corneal/conjunctival sign scores of each treatment group at baseline and 3mo after treatments were compared and both drugs were found to be effective on rosacea associated ocular changes(P <0.001). Cyclosporine was more effective in symptomatic relief and in the treatment of eyelid signs(P =0.01). There was statistically significant increase in the mean Schirmer score with anesthesia and tear break up time scores in the cyclosporine treatment group compared to the doxycycline treatment group(P <0.05).CONCLUSION: Cyclosporine as a topical drug can be used in the treatment of rosacea associated ocular complications because it is more effective than doxycycline. In addition ocular rosacea as a chronic disease requires long term treatment and doxycycline has various side effects limiting its long term usage. | Aysegul Arman Duriye Deniz Demirseren Tamer Takmaz | 2015 | International Journal of Ophthalmology(English edition)2015，8，3： | 7 |
| 10 | Hybrid algorithm for modeling of fluid-structure interaction in incompressible, viscous flows显示文摘The objective of this paper is to present and to validate a new hybrid coupling (HC) algorithm for modeling of fluid-structure interaction (FSI) in incompressible, viscous flows. The HC algorithm is able to avoid numerical instability issues associated with artificial added mass effects, which are often encountered by standard loosely coupled (LC) and tightly coupled (TC) algorithms, when modeling the FSI response of flexible structures in incompressible flow. The artificial added mass effect is caused by the lag in exchange of interfacial displacements and forces between the fluid and solid solvers in partitioned algorithms. The artificial added mass effect is much more prominent for light/flexible structures moving in water, because the fluid forces are in the same order of magnitude as the solid forces, and because the speed at which numerical errors propagate in an incompressible fluid. The new HC algorithm avoids numerical instability issues associated with artificial added mass effects by embedding Theodorsen's analytical approximation of the hydroelastic forces in the solution process to obtain better initial estimates of the displacements. Details of the new HC algorithm are presented. Numerical validation studies are shown for the forced pitching response of a steel and a plastic hydrofoil. The results show that the HC algorithm is able to converge faster, and is able to avoid numerical instability issues, compared to standard LC and TC algorithms, when modeling the transient FSI response of a plastic hydrofoil. Although the HC algorithm is only demonstrated for a NACA0009 hydrofoil subject to pure pitching motion, the method can be easily extended to model general 3-D FSI response and stability of complex, flexible structures in turbulent, incompressible, multiphase flows. | Eun Jung Chae Deniz Tolga Akcabay | 2012 | Acta Mechanica Sinica2012，28，4： | 6 |
| 11 | Class-specific differential detection in diffractive optical neural networks improves inference accuracy显示文摘Optical computing provides unique opportunities in terms of parallelization,scalability,power efficiency,and computational speed and has attracted major interest for machine learning.Diffractive deep neural networks have been introduced earlier as an optical machine learning framework that uses task-specific diffractive surfaces designed by deep learning to all-optically perform inference,achieving promising performance for object classification and imaging.We demonstrate systematic improvements in diffractive optical neural networks,based on a differential measurement technique that mitigates the strict nonnegativity constraint of light intensity.In this differential detection scheme,each class is assigned to a separate pair of detectors,behind a diffractive optical network,and the class inference is made by maximizing the normalized signal difference between the photodetector pairs.Using this differential detection scheme,involving 10 photodetector pairs behind 5 diffractive layers with a total of 0.2 million neurons,we numerically achieved blind testing accuracies of 98.54%,90.54%,and 48.51%for MNIST,Fashion-MNIST,and grayscale CIFAR-10 datasets,respectively.Moreover,by utilizing the inherent parallelization capability of optical systems,we reduced the cross-talk and optical signal coupling between the positive and negative detectors of each class by dividing the optical path into two jointly trained diffractive neural networks that work in parallel.We further made use of this parallelization approach and divided individual classes in a target dataset among multiple jointly trained diffractive neural networks.Using this class-specific differential detection in jointly optimized diffractive neural networks that operate in parallel,our simulations achieved blind testing accuracies of 98.52%,91.48%,and 50.82%for MNIST,Fashion-MNIST,and grayscale CIFAR-10 datasets,respectively,coming close to the performance of some of the earlier generations of all-electronic deep neural networks,e.g.,LeNet,which achieves classification accuracies of 98.77%,90.27%,and 55.21%corresponding to the same datasets,respectively.In addition to these jointly optimized diffractive neural networks,we also independently optimized multiple diffractive networks and utilized them in a way that is similar to ensemble methods practiced in machine learning;using 3 independently optimized differential diffractive neural networks that optically project their light onto a common output/detector plane,we numerically achieved blind testing accuracies of 98.59%,91.06%,and 51.44%for MNIST,Fashion-MNIST,and grayscale CIFAR-10 datasets,respectively.Through these systematic advances in designing diffractive neural networks,the reported classification accuracies set the state of the art for all-optical neural network design.The presented framework might be useful to bring optical neural network-based low power solutions for various machine learning applications and help us design new computational cameras that are task-specific. | Jingxi Li Deniz Mengu Yi Luo Yair Rivenson Aydogan Ozcan | 2019 | Advanced Photonics2019，1，4： | 6 |
| 12 | Long-term aspirin pretreatment in the prevention of cerulein-induced acute pancreatitis in rats显示文摘AIM:To investigate the effects of long term pretreatment with low-,medium-and high-dose aspirin(acetylsalicylic acid,ASA) on a model of acute pancreatitis(AP) induced in rats.METHODS:Forty male Wistar rats were used.Three experimental groups,each consisting of eight animals,received low-(5 mg/kg per day),medium-(150 mg/kg per day) and high-dose(350 mg/kg per day) ASA in supplemented pellet chow for 100 d.Eight animals,serving as the AP-control group,and another eight,serving as reference value(RV) group,were fed with standard pellet chow for the same period.After pretreatment,AP was induced in the experimental animals by intraperitoneal administration of cerulein(2 × 50 μg/kg),while the RV group received saline in the same way.Twelve hours after the second injection,the animals were sacrificed.Pancreatic tissue and plasma samples were collected.One part of the collected pancreatic tissues was used for histopathological evaluation,and the remaining portion was homogenized.Cytokine levels [tumor necrosis factor,interleukin(IL)1β,IL-6],hemogram parameters,biochemical parameters(amylase and lipase),nuclear factor-κB,aspirin triggered lipoxins and parameters related to the antioxidant system(malondialdehyde,nitric oxide,hemeoxygenase-1,catalase and superoxide dismutase) were measured.RESULTS:Cerulein administration induced mild pancreatitis,characterized by interstitial edema(total histopathological score of 5.88 ± 0.44vs 0.25 ± 0.16,P < 0.001).Subsequent pancreatic tissue damage resulted in an increase in amylase(2829.71 ± 772.48 vs 984.57 ± 49.22 U/L,P = 0.001) and lipase(110.14 ± 75.84 U/L vs 4.71 ± 0.78 U/L,P < 0.001) in plasma,and leucocytes(6.89 ± 0.48 vs 4.36 ± 0.23,P = 0.001) in peripheral blood.Cytokines,IL-1β(18.81 ± 2.55 pg/μg vs 6.65 ± 0.24 pg/μg,P = 0.002) and IL-6(14.62 ± 1.98 pg/μg vs 9.09 ± 1.36 pg/μg,P = 0.04) in pancreatic tissue also increased.Aspirin pretreatment reduced the increase in the aforementioned parameters to a certain degree and partially improved the histopathological alterations caused by cerulein.No evidence of side effects related to chronic ASA administration(e.g.,inflammation or bleeding) was observed in the gastrointestinal tract in macroscopic and histopathological examination.CONCLUSION:Long term ASA pretreatment could prevent and/or ameliorate certain hematological,serological and histological alterations caused by ceruleininduced AP. | Ibrahim Akyazi Evren Eraslan Ahmet Gülubuk Elif Ergül Ekiz Zeynep L rakli Damla Haktanir Deniz Aktaran Bala Mete zkurt Erdal Matur Mukaddes zcan | 2013 | World Journal of Gastroenterology2013，19，19： | 5 |
| 13 | Biliary fistula after treatment for hydatid disease of the liver:When to intervene显示文摘AIM:To determine the outcome of patients with biliary fistula(BF)after treatment for hydatid disease of the liver. METHODS:Between January 2000 and December 2010,out of 301 patients with a diagnosis of hydatid cyst of the liver,282 patients who underwent treatment [either surgery or puncture,aspiration,injection and reaspiration(PAIR)procedure]were analysed.Patients were grouped according to the presence or absence of postoperative biliary fistula(PBF)(PBF vs no-PBF groups,respectively).Preoperative clinical,radiological and laboratory characteristics,operative characteristics including type of surgery,peroperative detection of BF,postoperative drain output,morbidity,mortality and length of hospital stays of patients were compared amongst groups.Multivariate analysis was performed to detect factors predictive of PBF.Receiver operative characteristics(ROC)curve analysis were used to determine ideal cutoff values for those variables found to be significant.A comparison was also made between patients whose fistula closed spontaneously(CS)and those with intervention in order to find predictive fac-tors associated with spontaneous closure. RESULTS:Among 282 patients[median(range)age, 23(16-78)years;77.0%male];210(74.5%)were treated with conservative surgery,33(11.7%)radical surgery and 39(13.8%)underwent percutaneous drainage with PAIR procedure A PBF developed in 46(16.3%) patients,all within 5 d after operation.The maximum cyst diameter and preoperative alkaline phosphatase levels(U/L)were significantly higher in the PBF group than in the no-PBF group[10.5±3.7 U/L vs 8.4±3.5 U/L(P<0.001)and 40.0±235.1 U/Lvs 190.0±167.3 U/L(P=0.02),respectively].Hospitalization time was also significantly longer in the PBF group than in the no-PBF group[37.4±18.0 d vs 22.4±17.9 d(P< 0.001)].A preoperative high alanine aminotransferase level(>40 U/L)and a peroperative attempt for fistula closure were significant predictors of PBF development (P=0.02,95%CI:-0.03-0.5 and P=0.001,95%CI:0.1-0.4),respectively.Comparison of patients whose PBF CS or with biliary intervention(BI)revealed that the mean diameter of the cyst was not significantly different between CS and BI groups however maximum drain output was significantly higher in the BI group(81.6± 118.1 cm vs 423.9±298.4 cm,P<0.001).Time for fistula closure was significantly higher in the BI group(10.1 ±3.7 d vs 30.7±15.1 d,P<0.001).The ROC curve analysis revealed cut-off values of a maximum bilious drainage<102 mL and a waiting period of 5.5 postoperative days for spontaneous closure with the sensitivity and specificity values of(83.3%-91.1%,AUC:0.90)and (97%-91%,AUC:0.95),respectively.The multivariate analysis demonstrated a PBF drainage volume<102 mL to be the only statistically significant predictor of spontaneous closure(P<0.001,95%CI:0.5-1.0). CONCLUSION:Patients with PBF after hydatid surgery often have complicated postoperative course with serious morbidity.Patients who develop PBF with an output <102 mL might be managed expectantly. | Nazif Zeybek Hakan Dede Deniz Balci Ali Kagan Coskun Ismail Hakki Ozerhan Subutay Peker Yusuf Peker | 2013 | World Journal of Gastroenterology2013，19，3： | 5 |
| 14 | Thermal entanglement in the mixed three-spin XXZ Heisenberg model on a triangular cell显示文摘We numerically investigate the thermal entanglements of spins(1/2, 1) and spins(1/2, 1/2) in the three-mixed(1/2, 1,1/2) anisotropic Heisenberg XXZ spin system on a simple triangular cell under an inhomogeneous magnetic field. We show that the external magnetic field induces strong plateau formation in the pairwise thermal entanglement for fixed parameters of the Hamiltonian in the cases of ferromagnetic and antiferromagnetic interactions. We also observe an unexpected critical point at finite temperature in the thermal entanglement of spins(1/2, 1) for the antiferromagnetic case, while the entanglement of spins(1/2, 1) in the ferromagnetic case and the entanglement of spins(1/2, 1/2) in both ferromagnetic and antiferromagnetic cases almost decay exponentially to zero with increasing temperature. The critical point in the entanglement of spins(1/2, 1) in the antiferromagnetic case may be a signature of the quantum phase transition at finite temperature. | Seyit Deniz Han Ekrem Aydiner | 2014 | Chinese Physics B2014，23，5： | 5 |

| 16 | 老年男性勃起功能及迟发性性腺功能减退症状与下尿路症状严重性的关系显示文摘本文旨在研究土耳其爱琴海地区的老年男性下尿路症状(LUTSs)、勃起功能障碍(ED)和有症状的迟发性性腺功能减退症(SLOH)三者间的关系。符合以下标准的500名男性患者被纳入该研究:40周岁以上;过去6个月内有稳定的性关系;在六个泌尿外科诊所之一进行过就诊登记。每位患者均行血清PSA、睾酮水平及尿流率的检测,并填写国际前列腺症状评分和生活质量评分(IPSS-QoL)量表、国际勃起功能指数(IIEF)问卷和老年男性症状(AMS)量表。在所有的研究对象中,23.9%的患者有轻度LUTSs,53.3%有中度LUTSS,22.8%有重度LUTSS。每组间总睾酮水平无明显差异。除此之外,69.6%的病人患有ED,且ED的发生率与LUTS严重性呈正相关。71.2%的患者出现SLOH(AMS〉27),且IPSS评分越高,严重的性腺功能减退症状的发生率也越高。相关性分析显示以上三种问卷分数之间有显著关联。总之,LUTS严重性是ED和SLOH的非年龄依赖性危险因素,LUTS严重性和SLOH症状之间似乎有显著的相关性,但还需要从病因学和生物学角度进行深入阐明。 | Ozan Bozkurt Deniz Bolat Omer Demir Oktay Ucer Ali Sahin Burak Ozcift Abdulkadir Pekta Tahir Turan Bilal H Gümü Ertan Cans Ahmet Bolukbasi Haluk Erol Adil Esenx | 2013 | Asian Journal of Andrology2013，15，6： | 4 |
| 17 | Effect of Boron and Heat Treatment on Mechanical Properties of White Cast Iron for Mining Application显示文摘Heat treatment methods were applied to white cast iron for improving the impact and wear resistance. Additionally, chemical composition optimization was made. Furthermore, the effect of boron addition on such applications was investigated. Samples were investigated by using optical and electron microscope methods. Hardness, wear and impact tests were conducted. The results showed that the secondary carbides in the standard alloy were iron-enriched, needle-like carbides M3C when the boron-added alloy contained Fe23(C,B)6 type, globular secondary carbides. It was concluded that heat treatment B provided higher wear and hardness properties, compared to the standard heat treatment. Optimum mechanical properties were obtained by lower destabilisation temperatures and increasing temperature reduced the wear resistance and hardness. | Havva Kazdal Zeytin Hakan Yildirim Banu Berme Selim Duduoglu Gürkan Kazdal Adem Deniz | 2011 | Journal of Iron and Steel Research(International)2011，18，11： | 4 |

| 19 | Can platelet count/spleen diameter ratio be used for cirrhotic children to predict esophageal varices?显示文摘AIM To determine the laboratory and radiologic parameters, including the platelet count(PC)-to-spleen diameter(SD) ratio as a non-invasive marker that may predict the presence of esophageal varices(EV) in children with cirrhosis.METHODS Eighty-nine patients with cirrhosis, but without a history of variceal bleeding were prospectively included. The children were grouped into 6-12 and 12-18 years of age groups. These groups were also divided into 2 subgroups(presence and absence of EV). All of the patients underwent a complete biochemical and radiologic evaluation. The PC(n/mm^3)-to-SD(mm) ratio was calculated for each patient. RESULTS Sixty-nine of 98(70.4%) patients had EV. The presence of ascites in all age groups was significantly associatedwith the presence of EV. There were no differences in serum albumin levels, PC, SD and the PC-to-SD ratio between the presence and absence of EV groups in both age groups(P > 0.05). CONCLUSION Laboratory and radiologic parameters, including the PC-to-SD ratio as a non-invasive marker(except for the presence of ascites), was inappropriate for detecting EV in children with cirrhosis. | Oya Balci Sezer Deniz Celik Nihal Tutar Figen Ozcay | 2016 | World Journal of Hepatology2016，8，33： | 4 |
| 20 | To image,or not to image:class-specific diffractive cameras with all-optical erasure of undesired objects显示文摘Privacy protection is a growing concern in the digital era,with machine vision techniques widely used throughout public and private settings.Existing methods address this growing problem by,e.g.,encrypting camera images or obscuring/blurring the imaged information through digital algorithms.Here,we demonstrate a camera design that performs class-specific imaging of target objects with instantaneous all-optical erasure of other classes of objects.This diffractive camera consists of transmissive surfaces structured using deep learning to perform selective imaging of target classes of objects positioned at its input field-of-view.After their fabrication,the thin diffractive layers collectively perform optical mode filtering to accurately form images of the objects that belong to a target data class or group of classes,while instantaneously erasing objects of the other data classes at the output field-of-view.Using the same framework,we also demonstrate the design of class-specific permutation and class-specific linear transformation cameras,where the objects of a target data class are pixel-wise permuted or linearly transformed following an arbitrarily selected transformation matrix for all-optical class-specific encryption,while the other classes of objects are irreversibly erased from the output image.The success of class-specific diffractive cameras was experimentally demonstrated using terahertz(THz)waves and 3D-printed diffractive layers that selectively imaged only one class of the MNIST handwritten digit dataset,all-optically erasing the other handwritten digits.This diffractive camera design can be scaled to different parts of the electromagnetic spectrum,including,e.g.,the visible and infrared wavelengths,to provide transformative opportunities for privacy-preserving digital cameras and task-specific data-efficient imaging. | Bijie Bai Yi Luo Tianyi Gan Jingtian Hu Yuhang Li Yifan Zhao Deniz Mengu Mona Jarrahi Aydogan Ozcan | 2022 | eLight2022，2，1： | 4 |
