| 1 | Intraarticular injections(corticosteroid, hyaluronic acid, platelet rich plasma) for the knee osteoarthritis显示文摘Osteoarthritis(OA)is a complex'whole joint'disease pursued by inflammatory mediators,rather than purely a process of'wear and tear'.Besides cartilage degradation,synovitis,subchondral bone remodeling,degeneration of ligaments and menisci,and hypertrophy of the joint capsule take parts in the pathogenesis.Pain is the hallmark symptom of OA,but the extent to which structural pathology in OA contributes to the pain experience is still not well known.For the knee OA,intraarticular(IA)injection(corticosteroids,viscosupplements,blood-derived products)is preferred as the last nonoperative modality,if the other conservative treatment modalities are ineffective.IA corticosteroid injections provide short term reduction in OA pain and can be considered as an adjunct to core treatment for the relief of moderate to severe pain in people with OA.IA hyaluronic acid(HA)injections might have efficacy and might provide pain reduction in mild OA of knee up to 24 wk.But for HA injections,the costeffectiveness is an important concern that patients must be informed about the efficacy of these preparations.Although more high-quality evidence is needed,recent studies indicate that IA platelet rich plasma injections are promising for relieving pain,improving knee function and quality of life,especially in younger patients,and in mild OA cases.The current literature and our experience indicate that IA injections are safe and have positive effects for patient satisfaction.But,there is no data that any of the IA injections will cause osteophytes to regress or cartilage and meniscus to regenerate in patients with substantial and irreversible bone and cartilage damage. | Egemen Ayhan Hayrettin Kesmezacar Isik Akgun | 2014 | World Journal of Orthopedics2014，5，3： | 36 |
| 2 | Radical vs conservative surgery for hydatid liver cysts:Experience from single center显示文摘AIM:To compare the efficacy and safety of radical and conservative surgical interventions for liver hydatid disease.METHODS:The study comprised 59 patients in two groups who had undergone radical and conservative surgical procedures for liver hydatid disease in our department between 2004 and 2009. Preoperative diagnostic tools,medical treatments,demographic and clinical characteristics,postoperative follow-up,and recurrence were compared in both groups. RESULTS:This non-randomized retrospective studyincluded 59 patients who had undergone liver hydatid disease surgery. The radical technique was used in 18 patients (mean age:42.1 ± 13.5 years,seven male,11 female),and the conservative technique was used in 41 patients (mean age:43.5 ± 13.9 years,17 male,24 female). The follow-up period ranged from 3 to 58 mo. Although operative time was significantly shorter in the conservative group (P < 0.001),recurrence was significantly reduced in the radical group (P = 0.045). No statistically significant differences were found in terms of hospitalization duration,cyst count and size,location,postoperative complications,scolicidal solution usage,or follow-up duration between the two groups.CONCLUSION:The more effective method for pre-venting postoperative recurrence is radical surgery. En-doscopic retrograde cholangiopancreatography for bile leakage in the early postoperative period may decrease the requirement for repeat surgery. | Sami Akbulut Ayhan Senol Arsenal Sezgin Bahri Cakabay Mehmet Dursun Omer Satici | 2010 | World Journal of Gastroenterology2010，16，8： | 19 |

| 4 | Comparison of the effects of bevacizumab and ranibizumab injection on corneal angiogenesis in an alkali burn induced model显示文摘·AIM:To investigate the effects of bevacizumab and ranibizumab on corneal neovascularization in an alkali burn-induced model of corneal angiogenesis. ·METHODS:Fifteen Wistar-Albino rats were divided randomly into 3 groups after chemical cauterization of the cornea. The first group received a single dose of 0.1mL saline solution as a control group whereas second and third groups received a single dose of 2.5mg bevacizumab or 1mg ranibizumab by subconjunctival injection, respectively. After three weeks, the rat corneas were evaluated by biomicroscopy and corneal photographs were taken. The percentage of neovascularization area, length of the longest new vessel, corneal oedema and corneal opacity scores were assessed. ·RESULTS:The analysis of digital photographs showed that the percentage of neovascularization area to the total corneal area, the length of the longest new vessel, corneal oedema and opacity scores were significantly lower in both study groups compared to the control group (P <0.05). Additionally, the percentage of corneal neovascularization area, the length of the longest new vessel and corneal opacity score were less with bevacizumab than ranibizumab. ·CONCLUSION:Subconjunctival bevacizumab and ranibizumab treatments may be effective methods in reducing corneal neovascularization. Furthermore, bevacizumab is more effective than ranibizumab in the inhibition of corneal neovascularization. | Ayhan Dursun Mustafa Kemal Arici Feyza Dursun Ayse Vural Ozec Mustafa Ilker Toker Haydar Erdogan Aysen Topalkara | 2012 | International Journal of Ophthalmology(English edition)2012，5，4： | 10 |
| 5 | Beneficiation of the gold bearing ore by gravity and flotation显示文摘Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and environmentally friendly operations. In this study, gold pre-concentrates were produced by the stepwise gravity separation and flotation techniques. The Knelson concentrator and conventional flotation were employed for the recovery of gold. Gold bearing ore samples were taken from Gümüshane Region, northern east part of Turkey. As a result of stepwise Knelson concentration experiments, a gold concentrate assaying around 620 g/t is produced with 41.4wt% recovery. On the other hand, a gold concentrate about 82 g/t is obtained with 89.9wt% recovery from a gold ore assaying 6 g/t Au by direct flotation. | Alim Gül Olga Kangal Ayhan A.

| 6 | Left-sided appendicitis:Review of 95 published cases and a case report显示文摘AIM:To give an overview of the literature on left-sided acute appendicitis (LSAA) associated with situs inversus totalis (SIT) and midgut malrotation (MM).METHODS:We present a new case of LSAA with SIT and a literature review of studies published in the English language on LSAA,accessed via PubMed and Google Scholar databases.RESULTS:Ninety-five published cases of LSAA were evaluated and a 25-year-old female,who presented to our clinic with left lower abdominal pain caused by LSAA,is reported.In the reviewed literature,fiftyseven patients were male and 38 were female with an age range of 8 to 82 years and a median age of 29.1 ± 15.9 years.Sixty-six patients had SIT,23 had MM,three had cecal malrotation,and two had a previously unnoted congenital abnormality.Fifty-nine patients had presentedto the hospital with left lower,14 with right lower and seven with bilateral lower quadrant pain,and seven subjects complained of left upper quadrant pain.The diagnosis was established preoperatively in 49 patients,intraoperatively in 19,and during the postoperative period in five;14 patients were aware of having this anomaly.The data of eight patients were not unavailable.Eleven patients underwent laparoscopic appendectomy,which was combined with cholecystectomy in two cases.Histopathological examination of the appendix specimens revealed adenocarcinoma in only two of 95 patients.CONCLUSION:The diagnosis of left lower quadrant pain is based on well-established clinical symptoms,physical examination and physician's experience. | Sami Akbulut Abdullah Ulku Ayhan Senol Mahmut Tas Yusuf Yagmur | 2010 | World Journal of Gastroenterology2010，16，44： | 9 |
| 7 | 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 |
| 8 | Same-day colonoscopy preparation with Senna alkaloids and bisacodyl tablets:A pilot study显示文摘AIM:To evaluate the efficacy of same-day bowel preparation with Senna alkaloids combined with bisacodyl tablets in routine colonoscopy procedures.METHODS:Between March and June 2013,a sameday bowel preparation was implemented in our endoscopy unit.The preparation consisted of a semi-liquid,fiber-free diet one day prior to the procedure,with two bisacodyl tablets after lunch and dinner,and 250 mL of Senna alkaloid with 1.5 L of drinking water at 6 am the day of the procedure.The quality control parameters of colonoscopy were evaluated and implemented according to the guidelines of the American Society for Gastrointestinal Endoscopy.The pre-procedure,duringprocedure and post-procedure patient data were collected and analyzed:(1) pre-procedure(age,gender,comorbid diseases,colonoscopy indications,complete lack of compliance with the bowel preparation protocol);(2) during-procedure(sedation dose,duration of colonoscopy,withdrawal time,cecal intubation rate,polyp detection rate,Boston Bowel Preparation Scores and presence of foam and clear liquid); and(3) postprocedure(visual analogue scale score,pain during the procedure,patient satisfaction and premature withdrawal due to the insufficient bowel preparation).RESULTS:A total of 75 patients were included in this study with a mean age of 54.64 ± 13.29 years; 53.3%(40/75) were female and 46.7%(35/75) were male.A complete lack of compliance with the bowel preparation protocol was seen in 6.7% of patients(5/75).The mean total duration of colonoscopy was 16.12 ± 6.51 min,and the mean withdrawal time was 8.89 ± 4.07 min.The cecal intubation rate was 93.8%(61/64) and the polyp detection rate was 40%(30/75).The mean Boston Bowel Preparation Score was 7.38 ± 1.81,with the following distribution:right colon,2.34 ± 0.89; transverse colon,2.52 ± 0.67; left colon,2.52 ± 0.63.The mean visual analogue scale score was 4.59 ± 1.57.Due to insufficient bowel preparation,seven patients(7/75; 9.3%) were asked to repeat the procedure.Of these,five patients had poor or modest compliance with the protocol,and two patients reported constipation.Premature withdrawal due to insufficient bowel preparation was 2.7%(2/75).The overall satisfaction with the protocol was 86.7%(65/75),with patients reporting they would prefer the same protocol in a repeat procedure.CONCLUSION:The same-day administration of Senna alkaloids appears to be a safe and effective bowel cleansing protocol for colonoscopy procedures. | Erdinc Yenidogan Ismail Okan Huseyin Ayhan Kayaoglu Gokhan Giray Akgul Mufit Sansal Servet Tali Zeki Ozsoy Mustafa Sahin | 2014 | World Journal of Gastroenterology2014，20，41： | 7 |

| 10 | Altered spontaneous contractions of the ileum by anesthetic agents in rats exposed to peritonitis显示文摘AIM:To investigate in vitro effects of propofol,midazolam and dexmedetomidine,which are commonly used anaesthesic or sedatives,on spontaneous contractions of the ileum both in normal rats and those exposed to hyperdynamic peritonitis.METHODS:Spontaneous contractions of isolated ileum muscle segments from sham operated rats and those exposed to peritonitis,were studied in vitro.The amplitude and the frequency of spontaneous contractions of ileum muscle segments were studied after adding dexmetetomidine,propofol,and midazolam to the organ bath in a cumulative manner.RESULTS:Both amplitude(85.2±6.6 vs 47.4±7.1)and frequency(32.8±4.6 vs 20.2±3.9)of spontaneous contractions in ileum smooth muscle segments were decreased significantly in the peritonitis group compared to the control group(P<0.05).Dexmedetomidine significantly increased the amplitude of spontaneous contractions(85.2±6.6 vs 152.0±5.4,P<0.05)whereas,propofol(85.2±6.6 vs 49.6±4.8,P<0.05)and midazolam(85.2±6.6 vs 39.2±4.5,P<0.05)decreased it in both control and peritonitis groups.The frequency of spontaneous contractions were significantly decreased by propofol in both control(32.8±4.6 vs 18.2±3.4,P<0.05)and peritonitis groups 20.2±3.9 vs 11.6±3.2,P<0.05).Dexmedetomidine and midazolam did not cause significant changes in the number of spontaneous contractions in both control and the peritonitis groups(P>0.05).CONCLUSION:Propofol,midazolam and dexmedetomidine have various in vitro effects on spontaneous contractions of the rat ileum.While dexmedetomidine augments the spontaneous contraction of the rat ileum,propofol attenuates it.However,the effects of these compounds were parallel in both control and peritonitis groups. | Cengiz Aydin Ihsan Bagcivan Sinan Gursoy Ahmet Altun Omer Topcu Ayhan Koyuncu | 2009 | World Journal of Gastroenterology2009，15，13： | 6 |
| 11 | The relationship between ischemic stroke and weather conditions in Duzce, Turkey显示文摘BACKGROUND: Weather conditions are thought to increase the risk of stroke occurrence. But their mechanism has not yet been clarified. We investigated possible relationships between ischemic stroke and weather conditions including atmospheric pressure, temperature, relative humidity, and wind speed.METHODS: One hundred and twenty-eight patients with ischemic stroke who had been admitted to our hospital between January 1 and December 31, 2010 were enrolled in this study. We investigated the relationship between daily cases and weather conditions the same day or 1, 2, and 3 days before stroke.RESULTS: A negative correlation was found between maximum wind speed and daily cases 3 days before stroke. As the relationship between daily cases and changes of weather conditions in consecutive days was evaluated, a negative correlation was found between daily cases and change of atmospheric pressure in the last 24 hours.CONCLUSIONS: The maximum wind speed 3 days before stroke and change of atmospheric pressure in the last 24 hours were found to increase the cases of ischemic stroke. We recommend that individuals at risk of ischemic stroke should pay more attention to preventive measures, especially on days with low maximum wind speed, on subsequent 3 days, and on days with low atmospheric pressure in the last 24 hours. | Harun Gunes Hayati Kandis Ayhan Saritas Suber Dikici Ramazan Buyukkaya | 2015 | World Journal of Emergency Medicine2015，6，3： | 6 |

| 13 | Recent management of urinary stone disease in a pediatric population显示文摘The incidence of stone disease has been increasing and the risk of recurrent stone formation is high in a pediatric population. It is crucial to use the most effective method with the primary goal of complete stone removal to prevent recurrence from residual fragments. While extracorporeal shock wave lithotripsy(ESWL) is still considered first line therapy in many clinics for urinary tract stones in children, endoscopic techniques are widely preferred due to miniaturization of instruments and evolution of surgical techniques. The standard procedures to treat urinary stone disease in children are the same as those used in an adult population. These include ESWL, ureterorenoscopy, percutaneous nephrolithotomy(standard PCNL or mini-perc), laparoscopic and open surgery. ESWL is currently the procedure of choice for treating most upper urinary tract calculi in a pediatric population. In recent years, endourological management of pediatric urinary stone disease is preferred in many centers with increasing experience in endourological techniques and decreasing sizes of surgical equipment. The management of pediatric stone disease has evolved with improvements in the technique and a decrease in the size of surgical instru-ments. Recently, endoscopic methods have been safely and effectively used in children with minor complications. In this review, we aim to summarize the recent management of urolithiasis in children. | Ozgu Aydogdu Ayhan Karakose Orcun Celik Yusuf Ziya Atesci | 2014 | World Journal of Clinical Pediatrics2014，3，1： | 5 |

| 17 | A PURCHASING DECISION: SELECTING A SUPPLIER FOR A CONSTRUCTION COMPANY显示文摘Supplier selection is one of the most crucial activities performed by organizations because of its strategic importance. Supplier selection is a multi-objective problem involving both quantitative and qualitative criteria. Over the years a number of quantitative approaches have been tried. Although the Analytic Hierarchy Process (AHP) has previously been used in supplier selection problems, one major weakness of the application-oriented AHP literature is that it tends to focus on the mechanics of AHP instead of on the theoretical and practical implications associated with finding a solution. Though it is one of the most extensively used Multiple Criteria Decision Analysis methodologies, our literature search indicated that most studies found the best solution and stopped there, ignoring sensitivity analysis. Performing sensitivity analysis is very important for practical decision making, sometimes even as important as finding the best solution. In this paper for the first time a comprehensive application of AHP for a real-world case is presented along with sensitivity analysis in choosing the best suppliers for a Turkish construction company. As a result of this study the company decided to allocate the order quantities between the two top suppliers. | Ozden BAYAZIT Birsen KARPAK Ayhan YAGCI | 2006 | Journal of Systems Science and Systems Engineering2006，15，2： | 3 |
| 18 | Redox active polymer metal chelates for use in flexible symmetrical supercapacitors:Cobalt-containing poly(acrylic acid)polymer electrolytes显示文摘The novel polymer metal chelate electrolytes(polychelates)were prepared by incorporation of cobalt sulfate(Co)into poly(acrylic acid)(PAA)host matrix.Quasi-solid state supercapacitor devices were fabricated using polychelates,PAA-Co X(X:3,5,7,and 10)where X represents the doping fraction(w/w)of Co in PAA.All polymer metal electrolytes were showed excellent bending-stretching properties,thermal stability and electrochemical durability with an optimum ionic conductivity of 3.15×10^(-4) S cm^(-1).Hierarchically porous activated carbon and nano-sized conductive carbon were used to form carbon composite symmetrical device electrodes.The electric double-layer capacitor(EDLC)and redox reactions of Co-incorporated polychelates at the interfaces of porous activated carbon provided an optimum specific capacitance of 341.33 F g^(-1) with a device of PAA-Co7,which is at least 15 times enhancement compared to the device of pristine PAA.The PAA-Co7 device also provided energy density of 21.25 Wh kg^(-1) at a power density of 117.69 W kg^(-1).A prolonged cyclic stability of the device exhibited superior capacitive performance after 10,000 charge-discharge cycles and the maintained 90%of its initial performance.In addition,the supercapacitor with a dimension of 1.5 cm×3 cm containing PAA-Co7 successfully operated the red-blue-green(RGB)LED light. | Emre Cevik Ayhan Bozkurt | 2021 | Journal of Energy Chemistry2021，30，4： | 3 |
| 19 | Effect of thermal treatment on the swelling and surface roughness of common alder and wych elm wood显示文摘Wood heat treatment has increased significantly in recent years and is still growing as an industrial process to improve some wood properties. We studied the change of swellingand surface roughness of common alder(Alnus glutinosa(L.) Gaertn. ssp.glutinosa) and wych elm(Ulmus glabra Huds.) woods after heat treatment at two different temperatures and durations. The temperatures were 180 and 200 C and the durations were 2 and 4 h. A stylus method was employed to evaluate the surface characteristics of the samples. Roughness measurements by the stylus method were made in the direction perpendicular to the fiber on the wood surface. Four main roughness parameters, mean arithmetic deviation of profile(Ra), mean peak-to-valley height(Rz), root mean square roughness(Rq), and maximum roughness(Ry) were used to evaluate the effect of heat treatment on the surface characteristics of the specimens. Swelling and surface roughness parameters(Ra, Rz, Ry, and Rq) differed significantly for two temperatures and two durations of heat treatment. Swelling and surface roughness values decreased with increasing treatment temperature and treatment times. | Ayhan Aytin Suleyman Korkul | 2016 | Journal of Forestry Research2016，27，1： | 3 |
| 20 | Acute intoxication cases admitted to the emergency department of a university hospital显示文摘BACKGROUND: This study aimed to describe the clinical and socio-demographic aspects of acute poisoning in 2010 in Duzce City, Northwest Anatolian Region of Turkey.METHODS: Acute poisoning was due to the intentional ingestion of drugs in young and adult people(≥16), who were treated at the Emergency Service of Duzce University Medical Hospital, Turkey from January 1, 2010 to December 31, 2010. In this retrospective and descriptive study, 95 patients were diagnosed with intoxications and 30 of them intentionally ingested drugs to commit suicide. Records of the patients diagnosed with intoxication were obtained from the Clinical Archive of the hospital. Their diagnoses were established according to the International Statistical Classification of Diseases and Related Health Problems. Codes X60-X84 of this classification were used to classify self-infringed drug injuries and drug poisoning.RESULTS: In this series, 35(36.8%) patients were male and 60 patients(63.2%) female. The male/female ratio was 1.0/1.7. The mean age of the patients was 33.1±14.2 years; 17(17.9%) patients were below 20 years old and 9(9.5%) were older than 50 years. Of these patients, 29(30.5%) were single, 7(7.4%) divorced or separated, and 59(62.1%) married. Their mean time for admission to the emergency service after the incident was 208±180(15–660) minutes. The mean time for admission to the emergency service for patients with food intoxication after the incident was 142±160 minutes, for those with drug intoxication 173±161 minutes, for those with carbon monoxide(CO) intoxication 315±209 minutes, and for those with undefined intoxication 289±166 minutes(P=0.005). Most of the intoxication cases occurred in winter(41.1%, 39 of 95 patients). Admissions to the emergency service were most common in December and April(21 and 16 of 95 patients, respectively). Sixty-five(68.4%) cases were involved in non-deliberate poisoning, whereas 30(31.6%) were involved in deliberate poisoning. Twenty-six of the 95 patients with acute poisonings had mortality risk at admission, however only one died from CO intoxication in the emergency service(1.1%). Suicide attempts were more common in females than in males(21 of 30 patients, 70%, P<0.05). CONCLUSION: In Duzce City of Turkey, most intoxication cases occurred in winter, especially in December. They had non-deliberate poisoning, but deliberate poisoning in suicide attempts was more common in females than in males. | Ertugrul Kaya Aylin Yilmaz Ayhan Saritas Serdar Colakoglu Davut Baltaci Hayati Kandis Ismail Hamdi Kara | 2015 | World Journal of Emergency Medicine2015，6，1： | 3 |
