1Is the neutrophil to lymphocyte ratio associated with liver fibrosis in patients with chronic hepatitis B?显示文摘AIM: To determine the association between the neutrophil to lymphocyte(N/L) ratio and the degree of liver fibrosis in patients with chronic hepatitis B(CHB) infection. METHODS: Between December 2011 and February 2013, 129 consecutive CHB patients who were admitted to the study hospitals for histological evaluation of chronic hepatitis B-related liver fibrosis were included in this retrospective study. The patients were divided into two groups based on the fibrosis score: individuals with a fibrosis score of F0 or F1 were included in the 'no/minimal liver fibrosis' group, whereas patients with a fibrosis score of F2, F3, or F4 were included in the 'advanced liver fibrosis' group. The Statistical Package for Social Sciences 18.0 for Windows was used to analyze the data. A P value of < 0.05 was accepted as statistically significant.RESULTS: Three experienced and blinded pathologists evaluated the fibrotic status and inflammatory activity of 129 liver biopsy samples from the CHB patients. Following histopathological examination, the 'no/minimal fibrosis' group included 79 individuals, while the 'advanced fibrosis' group included 50 individuals. Mean(N/L) ratio levels were notably lower in patients with advanced fibrosis when compared with patients with no/minimal fibrosis. The mean value of the aspartate aminotransferase-platelet ratio index was markedly higher in cases with advanced fibrosis compared to those with no/minimal fibrosis.CONCLUSION: Reduced levels of the peripheral blood N/L ratio were found to give high sensitivity, specificity and predictive values in CHB patients with significant fibrosis. The prominent finding of our research suggests that the N/L ratio can be used as a novel noninvasive marker of fibrosis in patients with CHB.Murat Kekilli Alpaslan Tanoglu Yusuf Serdar Sakin Mevlut Kurt Serkan Ocal Sait Bagci 2015World Journal of Gastroenterology2015,21,18:15

4Treatment of retinopathy of prematurity: a review of conventional and promising new therapeutic options显示文摘Retinopathy of prematurity (ROP), a retinal vascular disease of premature infants, continues to be a major cause of preventable childhood blindness all over the world. The incidence of ROP varies among countries, being influenced by the quality of the level of neonatal intensive care. Here, we discuss the potential treatments that are now available or will soon or probably be available for ROP. Although ablation of the avascular retina with laser photocoagulation remains the current gold standard and well established therapy for ROP, some new therapeutic options including angiostatic therapies are being explored based on our knowledge of the pathophysiology of the ROP and complications and efficacy of laser treatment. However, prevention of the development of severe ROP and screening for ROP seem to be the best strategy in avoiding visual impairment caused by ROP in premature infants. New therapeutic interventions including vascular endothelial growth factor antibody administration, gene therapy and supplemental therapies should be supported with evidence-based data for the treatment of ROP.Fatih Mehmet Mutlu Umit Serdar Sarici 2013International Journal of Ophthalmology(English edition)2013,6,2:11

6Leptin levels in the differential diagnosis between benign and malignant ascites显示文摘AIM: To evaluate the role of leptin levels in the differential diagnosis of ascites. METHODS: Ascitic leptin, TNFα and serum leptin levels were measured in 77 patients with ascites (35 with malignancies, 30 cirrhosis and 12 tuberculosis). Control serum samples were obtained from 20 healthy subjects. Leptin and TNFα levels were measured by ELISA. Body mass index (BMI) and percentage of body fat (BFM) by skin fold measurement were calculated for all patients and control groups. Peritoneal biopsy, ascites cytology and cultures or biochemical values were used for the diagnosis of patients. RESULTS: In patients with malignancies, the mean serum and ascites leptin levels and their ratios were significantly decreased compared to the other patient groups and controls. In tuberculosis peritonitis, ascitic fluid TNFα levels were significantly higher than malignant ascites and cirrhotic sterile ascites. BMI and BFM values did not distinguish between patients and controls. CONCLUSION: In patients with malignant ascites, levels of leptin and TNFα were significantly lower than in patients with tuberculous ascites.Mehmet Buyukberber Mehmet Koruk M Cemil Savas Murat T Gulsen Yavuz Pehlivan Rukiye Deveci Alper Sevinc Serdar Gergerlioglu 2007World Journal of Gastroenterology2007,13,3:7
7Impacts of low-intensity prescribed fire on microbial and chemical soil properties in a Quercus frainetto forest显示文摘Prescribed fire is a common economical and effective forestry practice, and therefore it is important to understand the effects of fire on soil properties for better soil management. We investigated the impacts of low-intensity prescribed fire on the microbial and chemical properties of the top soil in a Hungarian oak(Quercus frainetto Ten.) forest. The research focused on microbial soil parameters(microbial soil respiration(RSM), soil microbial biomass carbon(Cmic) and metabolic quotient(qCO_2) and chemical topsoil properties(soil acidity(pH),electrical conductivity(EC), carbon(C), nitrogen(N), C/N ratio and exchangeable cations). Mean annual comparisons show significant differences in four parameters(C/N ratio,soil pH, Cmic and qCO_2) while monthly comparisons do not reveal any significant differences. Soil pH increased slightly in the burned plots and had a significantly positive correlation with exchangeable cations Mg, Ca, Mn and K.The mean annual C/N ratio was significantly higher in the burned plots(28.5:1) than in the control plots(27.0:1). The mean annual Cmic(0.6 mg g^(-1)) was significantly lower although qCO_2(2.5 lg CO_2–C mg Cmic h^(-1)) was significantly higher, likely resulting from the microbial response to fire-induced environmental stress. Low-intensity prescribed fire caused very short-lived changes. The annual mean values of C/N ratio, pH, Cmic and qCO_2 showed significant differences.Serdar Akburak Yowhan Son Ender Makineci Meric Cakir 2018Journal of Forestry Research2018,29,3:6
8Endoscopic vs external dacryocystorhinostomy-comparison from the patients' aspect显示文摘·AIM: To compare the success and complication rates,duration of surgeries and clinical comfort after endoscopic dacryocystorhinostomy(END-DCR) or external dacryocysto-rhinostomy(EXT-DCR).·METHODS: Fifty patients who underwent EXT- or END-DCR between January 2010-2012 were involved in the study. A questionnaire was applied to patients preoperatively, and postoperatively. Subjective success was defined by absence of epiphora, objective success by a normal nasolacrimal lavage and a positive functional endoscopic dye test(FEDT). Postoperative pain and cosmetic result of surgery were interpreted by the patients, who were also asked whether they would offer this surgery to a friend or would prefer this surgery once more if necessary.·RESULTS: Twenty-five patients underwent END-DCR and 25 underwent EXT-DCR. Mean duration of surgeries were 35 min both for EXT-DCR(30-50) and END-DCR(35-50)(P =0.778). Intraoperative bleeding were documented in 48% of EXT-DCR and 4% of END-DCR cases(P <0.001). In total 96% of EXT-DCR and 100% of END-DCR patients had subjective success. Objective success was 100% in each group. There was no significant difference between the epiphora scorings and FDDT results in postoperative visits among the groups.END-DCR group reported less pain in first week and month(P <0.05, P <0.05). More patients in END-DCR group were happy with the cosmetic result in first week and month(P <0.001, P <0.001). More patients in END-DCR group offered this surgery to a friend(P <0.001). All patients in END-DCR group preferred this surgery once more if necessary, only 48% in EXT-DCR preferred the same method(P <0.001).·CONCLUSION: Although both END- and EXT-DCRs provide satisfactory outcomes with similar objective andsubjective success rates, we demonstrated that the endonasal approach caused significantly less pain in early postoperative period than the external approach.Clinical comfort defined by the patients was quite higher in END-DCR group, in which patients mainly were pleased to encounter a sutureless surgical area.Serdar Ozer Pinar A.

9Retroperitoneal laparoscopic nondismembered pyeloplasty for uretero-pelvic junction obstruction due to crossing vessels: A matched-paired analysis and review of literature显示文摘Objective:To compare laparoscopic Anderson-Hynes pyeloplasty(LAHP)and retroperitoneal laparoscopic YV-pyeloplasty(LRYVP)in ureteropelvic junction obstruction(UPJ)in presence of a crossing vessels(CV).Methods:Our database showed 380 UPJO-cases,who underwent laparoscopic retroperitoneal surgery during the last 2 decades including 206 non-dismembered LRYVP,157 dismembered pyeloplasties LAHP,and 17 cases of laparoscopic ureterolysis.Among them 198 cases were suitable for a matched-pair(2:1)analysis comparing laparoscopic retroperitoneal non-dismembered LRYVP(Group 1,n Z 131)and dismembered LAHP(Group 2,n Z 67)in presence of a crossing vessel.Patients were matched according to age,gender,kidney functions,and obstruction grade.Complications were graded according to modified Clavien-classification.Results:Comparative data were similar between both groups(LRYVP vs.LAHP)including mean operating time(112 min vs.114 min),complication rates(4.2%vs.7.3%)mainly Grade 1e2 according to Clavien classification,and success rates(90%vs.89%).These results reflected in the reviewed literature indicate that LRYVP provides the advantage of minimal dissection in case of CV with similar outcome.However,redundant pelvis and anteriorly crossing vessels still require a dismembered pyeloplasty LAHP.Conclusion:LRYVP has achieved similar results compared with the previous golden standard of open surgery,especially in case of crossing vessels apart from presence of a redundant pelvis or anteriorly crossing vessel.This can be further improved when using the small access retroperitoneoscopic technique respectively mini-laparoscopy.Jens Rassweiler Jan Klein Ali Serdar Goezen 2018Asian Journal of Urology2018,5,3:5
10Drag pick cutting tests: A comparison between experimental and theoretical results显示文摘This paper aims at reporting the results of a number of drag pick cutting tests on selected igneous rock samples to compare the experimentally determined maximum cutting force(FC') values with theoretically estimated ones. First, a review on theoretical rock cutting models proposed for both chisel and conical picks was presented in detail. Experimental study consists of both chisel and conical pick cutting tests in unrelieved(single-pick) cutting mode with varying cutting depths. FC' values were determined from experimental results, and theoretical models were utilized to compute FC' for all cutting conditions.Computed and experimentally determined FC' data were then compared for a referenced cutting depth. It is shown that the theoretical models might overestimate or underestimate FC' and cannot give reliable results. Finally, explanations for these mismatches were presented.Serdar Yasar Ali Osman Yilmaz 2018Journal of Rock Mechanics and Geotechnical Engineering2018,10,5:5
11KAP Survey of Turkish University Students on Sexuality,reproductive Health,Drug Addiction and Violence显示文摘Objective To investigate the attitudes, behaviours and reflections of the university students, on sexuality, reproductive health, violence, smoking, alcohol and drug use, and to find out their expectations from a youth health service. Methods A total of 5 300 students (1 880 girls, 3 420 boys) from various faculties of Kyrykkale University were enrolled into this cross-sectional study. Students com- pleted the self-administered questionnaire as one of the researchers was present at the classroom. Research monitors five categories of priority health-risk behaviours among youth and young adults. Results Mean age of 3 420 male (64.5%) and 1 880 female (35.5%) students were 20.3 years. Among all 4 380 (82.9%) students [1 350 girls (71.8%), 3 030 boys (88.5%)] had some kinds of information about sexuality, however this dropped to 2 730 students (51.5%) within the context of adequacy. Friends were the major source (34%) for the first information on sexuality. Using a condom was the mostly heard method of contraception (46.9%) and interestingly 1.1% of the students had no knowledge on any of the protection methods. Among all 25.3% of the students (33.0% boys, 11.4% girls) had some kind of sexual intercourse, and within this group 58.8% experienced his/her first sexual relationship at 18 years of age and over; 53.9% were protected in all intercourses. Using a condom was the main way of protection for boys (63.7%) and pills were for the girls (73.9%). None of the female students mentioned having an abortion but 8% had friends who had undergone abortion. Tobacco use was 35.1% among the group, and 8.7% of the male and 3.6% of the female students were using drugs. Although 67.4% students claimed they never witnessed violence between their parents, 43.2% witnessed violence among their siblings, 67.0% beween friends, 72.6% in the streets and 64.2% in the school. About 30.0% of the students reported having weight problems, and 14.7% admitted visiting a doctor for that problem. If there would be a service provided for the adolescents in the university, 67% of thestudents would attend in case of a problem. Past experiences were important for us and we saw that among all 8% of the participants had some kind of sexual problem, within this group 50.7% felt uncomfortable during the visit and only 60.4% were satisfied with the care of the physician. Conclusion Our study results show the current situation of adolescents in Kyrykkale University and will be used to improve policies and programs to reduce priority health- risk behaviours among youth of our and surrounding provinces and establish a youth friendly service in Kyrykkale University within this purposes.H■zel Selda Sanli Cihat Albayrak Meryem Fidan Serdar Agar Ayca 2006Journal of Reproduction and Contraception2006,17,4:4
12Clustering Seismic Activities Using Linear and Nonlinear Discriminant Analysis显示文摘Identification and classification of different seismo-tectonic events with similar characteristics in a region of interest is one of the most important subjects in seismic hazard studies.In this study,linear and nonlinear discriminant analyses have been applied to classify seismic events in the vicinity of Istanbul.The vertical components of the digital velocity seismograms are used for seismic events with magnitude(Md)between 1.8 and 3.0 that occurred between 2001 and 2004.Two,time dependent parameters,complexity and S/P peak amplitude ratio are selected as predictands.Linear,quadratic,diaglinear and diagquadratic discriminant functions are investigated.Accuracy of methods with an additional adjusted quadratic models are 96.6%,96.6%,95.5%,96.6%,and 97.6%,respectively with a various misclassified rate for each class.The performances of models are justified with cross validation and resubstitution error.Although all models remarkably well performed,adjusted quadratic function achieved the best success rate with just 4 misclassified events out of 179,even better compared to complex methods such as,self organizing method,k-means,Gaussion mixture models that applied to same dataset in literature.H Serdar Kuyuk Eray Yildirim Emrah Dogan Gunduz Horasan 2014Journal of Earth Science2014,25,1:4

14Laryngopharyngeal reflux and Helicobacter pylori显示文摘Laryngopharyngeal reflux(LPR) occurs when gastric contents pass the upper esophageal sphincter, causing symptoms such as hoarseness, sore throat, coughing, excess throat mucus, and globus. The pattern of reflux is different in LPR and gastroesophageal reflux. LPR usually occurs during the daytime in the upright position whereas gastroesophageal reflux disease more often occurs in the supine position at night-time or during sleep. Ambulatory 24-h double pH-probe monitoring is the gold standard diagnostic tool for LPR. Acid suppression with proton pump inhibitor on a long-term basis is the mainstay of treatment. Helicobacter pylori(H. pylori) is found in many sites including laryngeal mucosa and interarytenoid region. In this paper, we aim to present the relationship between LPR and H. pylori and review the current literature.Taner Yllmaz Münir Demir Bajin Rlza nder Günayd?n Serdar zer Tevfik Szen 2014World Journal of Gastroenterology2014,20,27:4
15Associations between Vaspin Levels and Coronary Artery Disease显示文摘The relationship between serum vaspin levels and metabolic or coronary artery disease is currently of interest for researchers.Although adipokine concentrations have been shown to be increased signifi cantly in atherosclerotic lesions,the role adipokines in the atherosclerotic process remains to be elucidated.Vaspin is a new biological marker associated with obesity and impaired insulin sensitivity.Plasma vaspin concentration has been shown to correlate with the severity of coronary artery disease.Vascular infl ammation triggered by vaspin inhibits atherogenesis by suppressing macrophage foam cell formation and vascular smooth muscle cell migration and proliferation.Vaspin also contributes to plaque stabilization by increasing collagen content and reducing the intraplaque macrophage to vascular smooth muscle cell ratio.The therapeutic goal concerning vaspin is to fi ght atherosclerosis and related diseases,as well as to maintain vascular health.Lutfu Askin Okan Tanriverdi Hakan Tibilli Serdar Turkmen 2020Cardiovascular Innovations and Applications2020,,1:3
16Acute 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 2015World Journal of Emergency Medicine2015,6,1:3
