| 1 | Targeted therapies in gastric cancer and future perspectives显示文摘Advanced gastric cancer(AGC) is associated with a high mortality rate and, despite multiple new chemotherapy options, the survival rates of patients with AGC remains poor. After the discovery of targeted therapies, research has focused on the new treatment options for AGC. In the last two decades, many targeted molecules were developed against AGC. Currently, two targeted therapy molecules have been approved for patients with AGC. In 2010, trastuzumab was the first molecule shown to improve survival in patients with HER2-positive AGC as part of a first-line combination regimen. In 2014, ramucirumab was the second targeted molecule to improve survival rates and was suggested as treatment for patients with AGC who had progressed after firstline platinum plus fluoropyrimidine with or without anthracycline chemotherapy. Ramucirumab was the first targeted therapy acting as a single agent in patients with advanced gastroesophageal cancers. Although these two molecules were introduced into clinical use, many other promising molecules have been tested in phase Ⅰ-Ⅱ trials. It is obvious that in the near future many different targeted therapies will be in use for treatment of AGC. In this review, the current status of targeted therapies in the treatment of AGC and gastroesophageal junction tumors, including HER(2-3) inhibitors, epidermal growth factor receptor inhibitors, tyrosine kinase inhibitors, antiangiogenic agents, c-MET inhibitors, mammalian target of rapamycin inhibitors, agents against other molecular pathways fibroblast growth factor, Claudins, insulin-like growth factor, heat shock proteins, and immunotherapy, will be discussed. | Ozan Yazici M Ali Nahit Sendur Nuriye Ozdemir Sercan Aksoy | 2016 | World Journal of Gastroenterology2016，22，2： | 11 |
| 2 | Flow structure at the downstream of a one-line riparian emergent tree along the floodplain edge in a compound open-channel flow显示文摘This study focuses on the effects of one-line emergent natural tree(Cupressus Macrocarpa) planted at the edge of the floodplain in a compound open-channel flow. The flow velocity and water level are measured and used to analyze the flow structure. The time averaged and depth-averaged streamwise velocity distributions with root mean square(rms) and time series of streamwise velocity distrbution are analyzed. The velocity distribution considerably changes along the compound channel. The streamwise velocity distribution fits with logarithmic distribution in the non-vegetated case, but for vegetated cases, the streamwise velocity distribution shows S shaped profile at the 1/3 part of floodplain(/3)B_f and main channel(/3)B_m close to the boundary between floodplain and main channel. Additionally, it is obtained that the presence of tree line increases turbulence intensity over the compound open-channel. Moreover, an oscillation period is obtained in the flow caused by tree line by analyzing time series of the streamwise velocity distribution. The oscillation is present everywhere in the floodplain and present at almost/3 B_m part of the main channel which is close to the junction between floodplain and main channel. | Ayse Yuksel Ozan | 2018 | Journal of Hydrodynamics2018，30，3： | 8 |
| 3 | Comparison of visual and topographic outcomes of deep-anterior lamellar keratoplasty and penetrating keratoplasty in keratoconus显示文摘AIM:To compare visual,surgical and topographic outcomes of deep anterior lamellar keratoplasty(DALK)and penetrating keratoplasty(PK)for keratoconus(KC).METHODS:In this multicenter,prospective,randomized clinical trial 76 eyes of 71 KC patients operated between January 2011 and July 2014 in 2 tertiary referral hospitals were included. Consecutive patients were alternately selected to receive one of the two surgical methods. Thirty eight eyes underwent DALK with the big-bubble technique and 38 eyes underwent PK.RESULTS:Mean best spectacle corrected visual acuity(BSCVA)at the first postoperative week(P=0.012)and the first postoperative month(P<0.001)was statistically significantly higher in DALK group. The mean BSCVA at12 mo was not significantly different for DALK(0.30±1.99 log MAR)versus PK(0.40±0.33 log MAR)(P=0.104). The76.3% of the eyes had a BSCVA over 0.5 in DALK and 47.4%in PK group(P=0.009). The 7.9% of the eyes had a BSCVA of 1.0 in DALK and 5.3% in PK group(P=0.644). Mean spherical equivalent was-2.94 D in DALK and-3.09 D in PK group.Mean topographic astigmatism was 4.62 D and 4.18 D respectively. Regular topographic patterns were observed in 31(81.6%)of DALK and 29(76.3%)of PK(P=0.574). The most frequent topographic pattern was oblate asymmetric bow tie,seen in 39.5% in DALK and 23.7% in PK. CONCLUSION:Big bubble DALK provides an earlier visual improvement compare to PK. However,visual and topographic outcomes are similar to those in PK at 1y. Postoperative complications including rejection and intraocular pressure elevation are more frequent in PK. DALK is a safer alternative to PK for KC. However,intraoperativeperforation of the Descemet's membrane is a significant complication. | Bora Yüksel Baran Kandemir Umut Duygu Uzunel Ozan Celik Sezgin Ceylan Tuncay Küsbeci | 2017 | International Journal of Ophthalmology(English edition)2017，10，3： | 5 |
| 4 | Material and regenerative properties of an osteon-mimetic cortical bone-like scaffold显示文摘The objective of this work was to fabricate a rigid,resorbable and osteoconductive scaffold by mimicking the hierarchical structure of the cortical bone.Aligned peptide-functionalize nanofiber microsheets were generated with calcium phosphate(CaP)content similar to that of the natural cortical bone.Next,the CaP-rich fibrous microsheets were wrapped around a microneedle to form a laminated microtube mimicking the structure of an osteon.Then,a set of the osteon-mimetic microtubes were assembled around a solid rod and the assembly was annealed to fuse the microtubes and form a shell.Next,an array of circular microholes were drilled on the outer surface of the shell to generate a cortical bone-like scaffold with an interconnected network of Haversian-and Volkmann-like microcanals.The CaP content,porosity and density of the bone-mimetic microsheets were 240 wt%,8%and 1.9 g/ml,respectively,which were close to that of natural cortical bone.The interconnected network of microcanals in the fused microtubes increased permeability of a model protein in the scaffold.The cortical scaffold induced osteogenesis and vasculogenesis in the absence of bone morphogenetic proteins upon seeding with human mesenchymal stem cells and endothelial colony-forming cells.The localized and timed-release of morphogenetic factors significantly increased the extent of osteogenic and vasculogenic differentiation of human mesenchymal stem cells and endothelial colony-forming cells in the cortical scaffold.The cortical bonemimetic nature of the cellular construct provided balanced rigidity,resorption rate,osteoconductivity and nutrient diffusivity to support vascularization and osteogenesis. | Danial Barati Ozan Karaman Seyedsina Moeinzadeh Safaa Kader Esmaiel Jabbari | 2019 | Regenerative Biomaterials2019，6，2： | 5 |
| 5 | Hepatitis C virus reactivation in cancer patients in the era of targeted therapies显示文摘The purpose of this review is to summarize the evidence of hepatitis C reactivation in cancer patients in the era of targeted therapies.Targeted therapies are novel therapeutics frequently used in cancer patients.During treatment with targeted therapies,viral replication is one of the major problems that can occur.The PubMed database,ASCO,and ASCO Gastrointestinal Cancer Symposium abstracts were searched up until September 15,2013 using the following search keywords:'targeted therapies,rituximab,alemtuzumab,brentuximab,hepatitis,hepatitis C reactivation,tyrosine kinase inhibitors,imatinib,mammalian target of rapamycin(mTOR)inhibitors,everolimus,anti-HER therapies,trastuzumab,pertuzumab,lapatinib,antiepidermal growth factor receptor therapies,cetuximab,panitumumab,and ipilimumab'.Papers considered relevant for the aim of this review were selected by the authors.The data about rituximab-induced hepatic flare in hepatitis C virus(HCV)positive patients is controver-sial.However,there is the possibility of life-threatening hepatic flare that can develop after HCV ribonucleic acid(HCV-RNA)viral load increases.Routine followup of liver function tests should be advised.Especially in high-risk patients,such as those with baseline chronic active hepatitis and cirrhosis,and where there are plans to administer rituximab concomitantly with corticosteroids,it is advised to have close follow-up of HCV viral load.The data is insufficient to make accurate statements about the association of alemtuzumab therapy and HCV reactivation.However,alemtuzumab may cause deep immunosuppression.Due to this,it is better to follow up with liver function tests and HCV RNA levels during alemtuzumab therapy.Brentuximab has effects on antibody dependent cellular toxicity and may decrease humoral immunity.Thus,we believe that during brentuximab treatment of HCV infected patients,clinicians may encounter hepatitis C reactivation.There have been no reported cases of hepatitis C reactivation with imatinib therapy.However,there are many reports of hepatitis B reactivation with imatinib treatment.Based on the evidence of hepatitis B reactivation with imatinib and the effects of imatinib on immune system functions,we suggest that imatinib therapy might be a risk factor for HCV reactivation.Anti-human epidermal growth factor receptor 2 therapies are not associated with hepatic flare in HCV infected patients.Post-transplant studies reported that mTOR was safely administered to patients with active hepatitis C without causing hepatic flare.Cetuximab and panitumumab have not been associated with HCV reactivation.Two cases of HCV infected melanoma were safely treated with ipilimumab without any HCV reactivation or hepatic flare.Targeted therapies are a new and emerging area of oncology treatment modalities.While treating HCV infected cancer patients,clinicians should be mindful of the immunosuppressive properties of targeted therapies.Further randomized trials are needed to establish algorithms for this issue. | Ozan Yazici Mehmet Ali Nahit ?endur Sercan Aksoy | 2014 | World Journal of Gastroenterology2014，20，22： | 5 |
| 6 | 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 |
| 7 | A case of solid pseudopapillary tumor of the pancreas显示文摘We present ultrasound, computed tomography and magnetic resonance imaging findings in a case with pancreatic solid pseudopapillary tumor and their correlations with histopathology. Ultrasound revealed a hypoechogenic mass, and computed tomography revealed a hypodense mass at the pancreatic head minimally enhanced after intravenous contrast agent administration. Magnetic resonance imaging showed a hypointense mass on unenhanced T1-weighted images including a hyperintense focus representing the hemorrhage. The lesion was hyperintense on T2- weighted images. On the postcontrast images the lesion showed peripheral thin contrast enhancement in arterial phase and enhanced slightly diffusely in venous and equilibrium phases. The patient underwent elective resection of the mass and pancreatoduodenectomy with jejunostomy tube placement. A final diagnosis of solid pseudopapillary tumor was made histopathologically. Solid pseudopapillary tumor is a rare pancreatic tumor. It is important to make the diagnosis preoperatively because with an adequate surgical resection the prognosis is good. A multimodalitary approach, especially magnetic resonance imaging can suggest the diagnosis without the need for biopsy. | Ozan Karatag Gulden Yenice Huseyin Ozkurt Muzaffer Basak Can Basaran Banu Yilmaz | 2006 | World Journal of Gastroenterology2006，12，38： | 4 |
