| 1 | Rhabdomyolysis with different etiologies in childhood显示文摘AIM To investigate different etiologies and management of the rhabdomyolysis in children.METHODS Eight pediatric rhabdomyolysis cases who applied to the Dokuz Eylul University Faculty of Medicine Department of Pediatric Nephrology with different etiologies between January 2004 and January 2012 were evaluated in terms of age, gender, admission symptoms, physical examination findings, factors provoking rhabdomyolysis, number of rhabdomyolysis attacks, laboratory results, family history and the final diagnosis received after the treatment. RESULTS Average diagnosis ages of eight cases were 129(24-192) ± 75.5 mo and five of them were girls. All of them had applied with the complaint of muscle pain, calf pain, and dark color urination. Infection(pneumonia) and excessive physical activity were the most important provocative factors and excessive licorice consumption was observed in one case. In 5 cases, acute kidney injury was determined and two cases needed hemodialysis. As a result of the further examinations; the cases had received diagnoses of rhabdomyolysis associated with mycoplasma pneumoniae, sepsis associated rhabdomyolysis, licorice-induced hypokalemic rhabdomyolysis, carnitine palmitoyltransferase Ⅱ deficiency, very long-chain acyl-CoA dehydrogenase deficiency, congenital muscular dystrophy and idiopathic paroxysmal rhabdomyolysis(Meyer-Betz syndrome).CONCLUSION It is important to distinguish the sporadic and recurrent rhabdomyolysis cases from each other. Recurrent rhabdomyolysis cases should follow up more regardful and attentive. | Demet Alaygut Meral Torun Bayram Belde Kasap Alper Soylu Mehmet Türkmen Salih Kavukcu | 2017 | World Journal of Clinical Pediatrics2017，6，4： | 5 |
| 2 | Trajectory Tracking of a Planer Parallel Manipulator by Using Computed Force Control Method显示文摘Despite small workspace, parallel manipulators have some advantages over their serial counterparts in terms of higher speed, acceleration, rigidity, accuracy,manufacturing cost and payload. Accordingly, this type of manipulators can be used in many applications such as in high-speed machine tools, tuning machine for feeding,sensitive cutting, assembly and packaging. This paper presents a special type of planar parallel manipulator with three degrees of freedom. It is constructed as a variable geometry truss generally known planar Stewart platform.The reachable and orientation workspaces are obtained for this manipulator. The inverse kinematic analysis is solved for the trajectory tracking according to the redundancy and joint limit avoidance. Then, the dynamics model of the manipulator is established by using Virtual Work method.The simulations are performed to follow the given planar trajectories by using the dynamic equations of the variable geometry truss manipulator and computed force control method. In computed force control method, the feedback gain matrices for PD control are tuned with fixed matrices by trail end error and variable ones by means of optimization with genetic algorithm. | Atilla BAYRAM | 2017 | Chinese Journal of Mechanical Engineering2017，30，2： | 5 |

| 4 | Success rates for various graft materials in tympanoplasty e A review显示文摘Objectives:The aim of this paper is to review how successful each type of grafts is in tympanoplasty.Methods:Pubmed,Google and the Proquest Central Database at Kırıkkale University were queried using the keywords“graft”,“success”“tympanoplasty”,“success rate”with the search limited to the period 1955 to 2017.Results:Various types of graft materials including temporalis fascia,cartilage,perichondrium,periosteum,vein,fat or skin have been used in the reconstruction of tympanic membrane(TM)perforation.Although temporalis fascia ensures good hearing is restored,there are significant concerns that its dimensional stability characteristics may lead to residual perforation,especially where large TM perforations are involved.The“palisade cartilage”and“cartilage island”techniques have been stated to increase the strength and stability of a tympanic graft,but they may result in a less functional outcome in terms of restoring hearing.Smoking habits,the size and site of a perforation,the expertise level of the operating surgeon,age,gender,the status of the middle ear mucosa and the presence of myringosclerosis or tympanosclerosis are all important in determining how successful a graft is.Conclusion:Although temporal fascia is the most commonly used graft material for tympanoplasty,poor graft stability may cause failure.This failure is due to the inclusion of connective fibrous tissue containing irregular elastic fibers present in the grafted fascia.Cartilage grafts offer better ability to resist infection,pressure,and cope with insufficient vascular supply.This means that cartilage grafts are suitable for use in revision cases. | Ali Bayram Nuray Bayar Muluk Cemal Cingi Sameer Ali Bafaqeeh | 2020 | Journal of Otology2020，15，3： | 4 |
| 5 | High adiponectin levels fail to protect against the risk of hypertension and,in women,against coronary disease:involvement in autoimmunity?显示文摘AIM:To investigate whether serum adiponectin protects against cardiometabolic risk in a population sample with prevailing metabolic syndrome.METHODS:Middle-aged adults representative of a general population with baseline circulating adiponectin measurements(n=1224)were analyzed prospectively at a mean of 3.8 years’follow-up,using continuous values or sex-specific tertiles.Total adiponectin was assayed by an ELISA kit.Type-2 diabetes was identified by criteria of the American Diabetes Association.Hypertension was defined as a blood pressure≥140 mmHg and/or≥90 mmHg and/or use of antihypertensive medication.Outcomes were predicted using Cox proportional hazards regression analysis in models that were controlled for potential confounders.RESULTS:In models of multiple linear regression,sex hormone-binding globulin,fasting insulin(inverse)and,in men,age were significant independent covariates of serum adiponectin which further tended in women to be positively associated with serum creatinine.Cox regression analyses for incident coronary heart disease(CHD),adjusted for sex,age,non-HDL cholesterol,waist circumference and C-reactive protein,revealed significant inverse association with adiponectin tertiles in men but not women(HR=0.66;95%CI:0.32-1.38 for highest tertile).Cox regression for type-2 diabetes in a similar model(wherein glucose replaced non-HDL cholesterol),adiponectin tertiles appeared to protect in each gender.HR for incident hypertension roughly displayed unity in each of the adiponectin tertiles(P-trend=0.67).CONCLUSION:High adiponectin levels failed to protect against the development of hypertension and,in women,against CHD,presumably paralleling impairment in renal function as well.Involvement of adiponectin in autoimmune complex with loss of antioxidative-antiatherogenic properties may be underlying. | Altan Onat Mesut Aydln Günay Can Bayram Kroglu Ahmet Karagz Servet Altay | 2013 | World Journal of Diabetes2013，4，5： | 3 |

| 7 | Association of inflammation with atrial fibrillation in hyperthyroidism显示文摘The aim of this studywas to evaluate the relationship between inflammation and development of atrial fibrillation (AF) in patients with hyperthyroidism.Methods A total of 65 patients with newly diagnosed hyperthyroidism, 35 of whom were in sinus rhythm and 30 of whom in AF. Thirty five age- and gender-matched patients in a control group were included in the study. Factors associated with the development of AF were evaluated by multivariate regression analysis. Results Factors associated with AF in multivariate analysis included high sensitivity C reactive protein (HsCRP) [odds ratio (OR): 11.19; 95% confidence interval (95% CI): 1.80–69.53; P = 0.003],free T4 (OR: 8.76; 95% CI: 2.09–36.7; P = 0.003), and left atrial diameter (OR: 1.25; 95% CI: 1.06–1.47; P = 0.008). Conclusions The results of the present study suggest that HsCRP, an indicator of inflammation, free T4 and left atrial diameter are associated with the development AF in patients with hyperthyroidism. | Mehmet Ozaydin Ali Kutlucan Yasin Turker Banu Koroglu Akif Arslan Bayram A.

| 9 | Clinical outcomes of lung metastasectomy in patients with colorectal cancer显示文摘AIM:To investigate prognostic factors of survival following curative,non-palliative surgical removal of lung metastases secondary to colorectal cancer (CRC).METHODS:Between 1999 and 2009,a radical metastasectomy with curative intent was performed on lung metastases in 21 patients with CRC (15 male and 6 female;mean age:57.4 ± 11.8 years;age range:29-74 years) who had already undergone primary tumour resection.RESULTS:The mean number of lung metastases ranged from one to five.The mean overall survival was 71 ± 35 mo (median:25 mo).After adjusting for potential confounders,multivariable Cox regression analyses predicted only the number of lung metastases (1 vs ≥ 2;hazard ratio:7.60,95% confidence interval:1.18-17.2,P=0.03) as an independent predictor of poor survival following lung resection for metastatic CRC.CONCLUSION:Resection of lung metastases is a safe and effective treatment in selected CRC patients with single lung metastases. | Omer Fatih Olmez Erdem Cubukcu Ahmet Sami Bayram Unsal Akcali Turkkan Evrensel Cengiz Gebitekin | 2012 | World Journal of Gastroenterology2012，18，7： | 3 |
| 10 | Dielectric and microstructural properties of YAG:Dy^(3+) ceramics显示文摘Yttrium aluminium garnet(Y_3 Al_5 O_(12):YAG) singly doped with Dy3+ at different concentrations was prepared by solid state reactions using repeated heating cycles over the temperature range of 1300-1600 ℃. X-ray powder diffraction analysis confirms the presence of a well-crystallized YAG perovskite phase with cubic structure(by Rietveld refinement). The rare earth dopant is successfully integrated into the YAG host lattice without any major changes in the original structure. The temperature dependence,up to 250 ℃, of the conductivity, dielectric constant, dielectric loss, and loss tangent, at various frequencies of up to 5.0 MHz for undoped and doped crystals is compared to understand the electrical and structural characteristics. The experimental results reveal that Dy3+ dopants in YAG crystal significantly influence the conductivity, dielectric constant, and lossy mechanisms, which is probably due to the 3 d-AI ions and 4 f-Dy ions incorporated at different positions of both tetrahedral and octahedral symmetries in YAG:xDy3+ ceramics. | Munirah Abdullah Almessiere Bayram Unal Abdulhadi Baykal | 2018 | Journal of Rare Earths2018，36，12： | 2 |
| 11 | Improvement in renal functions with transcatheter aortic valve implantation显示文摘BACKGROUND & OBJECTIVES:In recent years, emerging transcatheter aortic valve implantation (TAVI) has become an alternative for surgery。 However, with advanced age, several co-morbid factors together with contrast agent usage can cause deterioration in renal function and increase in the risk of acute kidney injury (AKI) with poor prognosis in patients with AKI。 Therefore, many patients cannot benefit from this treatment。 In this study, we aim to examine the effects of TAVI on renal functions。 METHODS AND RESULTS: Seventy patients, mean age of 77.6 years, underwent TAVI between July 2011 and December 2012。 Estimated glomerular filtration rate (eGFR) was calculated by using the Cockcroft and Gault Formula。 Patients were monitored for 48 h for urine output。 Stage 1 AKI, according to the VARC-2 AKIN system, developed in only five (7.1%) of the patients after the procedure。 There was a statistically significant increase between the mean 1(st) month eGFRs before (68。2 vs。 61.0, P < 0.01) and after (68。2 vs。 63.6, P < 0.05) the TAVI in the cohort。 After TAVI (48。5 mL/min, P < 0.01) and the 1(st) month (52.1 mL/min, P < 0.01), the eGFR of the 36 (51.4%) patients diagnosed with chronic kidney disease before the procedure showed a statistically significant increase in renal functions。 The hospital mortality rate was higher in the group which developed AKI (P < 0.01)。 First month eGFR showed a more statistically significant increase than pre-TAVI eGFR (62.8 and 69.8, P < 0.05, respectively) in AKI developing patients and this difference - though statistically not significant - continued into the sixth month。 CONCLUSIONS: In this study, we showed that the treatment of aortic stenosis through TAVI allows improvement of renal functions, and that AKI rates will be lower with careful patient selection, proper pre-procedural hydration, and careful use of contrast agent。 | Telat Keleş Huseyin Ayhan Durmaz Sarı Aslan AN Erdoğan KE Kasapkara Bilen Bayram Akçay Bozkurt | 2013 | Journal of Geriatric Cardiology2013，10，4： | 2 |
| 12 | Tuning the metal filling fraction in metal-insulator-metal ultra-broadband perfect absorbers to maximize the absorption bandwidth显示文摘In this paper, we propose a methodology to maximize the absorption bandwidth of a metal-insulator-metal(MIM) based absorber. The proposed structure is made of a Cr-Al_2O_3-Cr multilayer design. At the initial step,the optimum MIM planar design is fabricated and optically characterized. The results show absorption above 0.9 from 400 nm to 850 nm. Afterward, the transfer matrix method is used to find the optimal condition for the perfect light absorption in an ultra-broadband frequency range. This modeling approach predicts that changing the filling fraction of the top Cr layer can extend light absorption toward longer wavelengths. We experimentally proved that the use of proper top Cr thickness and annealing temperature leads to a nearly perfect light absorption from 400 nm to 1150 nm, which is much broader than that of a planar design. Therefore, while keeping the overall process lithography-free, the absorption functionality of the design can be significantly improved. The results presented here can serve as a beacon for future performance-enhanced multilayer designs where a simple fabrication step can boost the overall device response without changing its overall thickness and fabrication simplicity. | AMIR GHOBADI HODJAT HAJIAN ALIREZA RAHIMI RASHED BAYRAM BUTUN EKMEL OZBAY | 2018 | Photonics Research2018，6，3： | 2 |

| 16 | 25 Gbps low-voltage hetero-structured silicongermanium waveguide pin photodetectors for monolithic on-chip nanophotonic architectures显示文摘Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits. | DANIEL BENEDIKOVIC LéOPOLD VIROT GUY AUBIN FARAH AMAR BERTRAND SZELAG BAYRAM KARAKUS JEAN-MICHEL HARTMANN CARLOS ALONSO-RAMOS XAVIER LE ROUX PAUL CROZAT ERIC CASSAN DELPHINE MARRIS-MORINI CHARLES BAUDOT FRéDéRIC BOEUF JEAN-MARC FéDéLI CHRISTOPHE KOPP LAURENT VIVIEN | 2019 | Photonics Research2019，7，4： | 2 |
| 17 | Radiological evaluation of patellofemoral instability and possible causes of assessment errors显示文摘Patellofemoral instability(PI)is the disruption of the patella’s relationship with the trochlear groove as a result of abnormal movement of the patella.To identify the presence of PI,conventional radiographs(anteroposterior,lateral,and axial or skyline views),magnetic resonance imaging,and computed tomography are used.In this study,we examined four main instability factors:Trochlear dysplasia,patella alta,tibial tuberosity–trochlear groove distance,and patellar tilt.We also briefly review some of the other assessment methods used in the quantitative and qualitative assessment of the patellofemoral joint,such as patellar size and shape,lateral trochlear inclination,trochlear depth,trochlear angle,and sulcus angle,in cases of PI.In addition,we reviewed the evaluation of coronal alignment,femoral anteversion,and tibial torsion.Possible causes of error that can be made when evaluating these factors are examined.PI is a multi-factorial problem.Many problems affecting bone structure and muscles morphologically and functionally can cause this condition.It is necessary to understand normal anatomy and biomechanics to make more accurate radiological measurements and to identify causes.Knowing the possible causes of measurement errors that may occur during radiological measurements and avoiding these pitfalls can provide a more reliable road map for treatment.This determines whether the disease will be treated medically and with rehabilitation or surgery without causing further complications. | Tugrul Ormeci Ismail Turkten Bayram Ufuk Sakul | 2022 | World Journal of Methodology2022，12，2： | 2 |
