Öğe Age, growth and reproduction of the Shabut Barbus grypus (Cyprinidae) in Atatürk dam lake (Euphrates river), Turkey(2008) Oymak S.A.; Dogan N.; Uysal E.Age, growth and reproduction of 243 shabut Barbus grypus Heckel, 1843 in Atatürk Dam Lake in Turkey were studied from June 2004 to July 2005. The population was composed of 13 age classes. Age groups, 4-6 for females and 2-4 for males, were dominant. The total length and weight of the individuals ranged from 145 to 960 mm in length and from 40 g to 11 kg respectively. The regression model fitted to the relation between length (FL) and weight (W) of fish was Log W = -4.6112 + 2.8835 Log FL (r2 = 0.989) for females, and Log W = -4.8607 + 2.9679 Log FL (r2 0.990) for males. The von Bertalanffy growth equations for females and males were found as Lt = 134.65 [1 -e-°10038(l+1.85731)] for females and Lt = 106.77 [1 - e-°13649 (t+1095)] for males. The total observed sex ratio was: 1.34 (females/males). The spawning period extended from May to July. Fecundity ranged from 16,000 to 235, 784.Öğe Biochemical and histopathological investigation of resveratrol, gliclazide, and losartan protective effects on renal damage in a diabetic rat model(Science Printers and Publishers Inc., 2015) Ezel T.; Kocyigit Y.; Deveci E.; Atamer Y.; Sermet A.; Uysal E.; Aktaş A.OBJECTIVE: To compare the protective effects of resveratrol, gliclazide, and losartan, at biochemical and histopathological levels, on the rat kidney with experimentally induced type 1 diabetes. STUDY DESIGN: A total of 35 adult male Wistar rats were divided into control, diabetic, diabetic gliclazide, diabetic resveratrol, and diabetic losartan groups. For biochemical analysis, based on one of the kidneys, superoxide dismutase, malondialdehyde, and catalase were used for measurement. The other kidney was stained for histochemical and immunohistochemical markers and examined by light microscopy. RESULTS: Nephropathy due to diabetes was developed at the end of the third week in the diabetic group: in the glomeruli, contraction from Bowman distance, diffuse mesangial matrix increasing and tubular dilation, and cytoplasmic vacuolar changes were observed. In tubulointerstitial areas, some tubular structures, an increased expression of VEGF was observed. CONCLUSION: As a result, in diabetic rats, the effects of gliclazide, resveratrol, and losartan cure were equivalent to each other according to the parameters which were followed. Resveratrol, gliclazide, and losartan significantly protected renal glomeruli and the proximal and distal tubules. © Science Printers and Publishers, Inc.Öğe Dental practitioner performance when incorporating attachments in implant-retained overdentures with unsplinted abutments(University of Dicle, 2015) Turkaslan S.S.; Deger Y.; Akan E.; Demirekin Z.B.; Kan S.; Uysal E.The aim of the present study was to evaluate the performance of dental practitioners incorporating attachments into overdenture prostheses, via the direct method, before and after an instructive course. Forty randomized gypsum models, with implants either angulated or parallel to each other, were given to forty dentists before and after an instructive course. A rubber dam or temporary light-curing composite resin was seated around the ball abutment, to avoid acrylic resin penetration while incorporating the attachments to the implant overdenture. A comparison of proportions test showed statistically significant differences between the rubber dam and temporary composite resin groups. There were no statistically significant differences between the groups with parallel and angulated abutments, before or after the course. Temporary light-curing composite resin as a block-out material is superior to a rubber dam, when incorporating attachments into the implant overdenture. The practitioners were more successful after the course, without considering the type of block-out material. The success of the practitioners was not affected by the angulation of the abutments before or after the course.Öğe Effects of potentilla fulgens as a prophylactic agent in testicular ischemia-reperfusion injury(Science Printers and Publishers Inc., 2016) Karabulut Ö.; Kalkanli S.T.; Deveci E.; Isen K.; Uysal E.; Söker I.S.Objective: To study the protective effects of Potentilla fulgens extract on damage of testicular tissue created by ischemia and reperfusion treatment via histopathological, immunohistochemical, and TUNEL experiments. STUDY DESIGN: In this study 24 Sprague-Dawley male rats were divided into 4 subgroups: control group, torsion group, torsion-detorsion group, and Potentilla fulgens+torsion-detorsion group. The extract of Potentilla fulgens was intraperitoneally injected into the rats, 400 mg/kg for 5 days. The right testicle was exposed to torsion and detorsion for 2 hours with a 720° turn. The right testicle was dissected from the scrotum after the rats were anesthetized with ketamine hydroxide. Following fixation of 10% formaldehyde solution, routine tissue processing protocol was applied. Immunohistochemically slides were stained with TNF-? antibody. Apoptotic changes were examined using the TUNEL protocol. Results: In this study seminiferous tubule diameter and depth of spermatic cells were compared among the experimental and control groups. Histopathologic examination shows that degeneration and disorganization of the spermatic cells and changes in tubule diameter were found to be statistically significant. In addition, histopathological examination of the apoptotic indices was scored using the TUNEL method. Immunohistochemically, TNF-? expression was positively observed in the ischemia and the ischemia-reperfusion groups. Conclusion: As a result of torsion and detorsion exposure, which led to damage in spermatic cells of seminiferous tubules, Potentilla fulgens was shown to decrease apoptotic development and was thought to be the cause of activation in spermatic cells. © Science Printers and Publishers, Inc.Öğe Electric injuries(2007) Orak M.; Üstündağ M.; Güloğlu C.; Uysal E.; Sayhan M.B.The electricity injury is the one of the major trauma causing mortality, and morbidity. We report 3 cases, admitted our emergiency department with electric injury caused by naked electric cable touching. All cases had compartment syndrome and undergone fasiotomy operations. They were transported to advanced intensive care units of burning. In this study, we would like to report that without any precaution and information, emergency depatment personals would be faced with interesting electric injuries that effect more than one people cases which havent been reported in medical literatures.Öğe Histological changes in the gingrval tissues of rats subjected to surgical extraction of the adrenal glands(2009) Dag A.; Ketani M.A.; Zengingul A.I.; Uysal E.; Baskan Z.Hormones are specific regulatory molecules that have potent effects on the major determinants of the development and the integrity of the skeleton and oral cavity also including periodontal tissues. The aim of this study, is to investigate the effect of adrenalectomy on rat gingival tissue. Twenty-eight mature Wistar albino female and male rats divided randomly into 2 groups and in one group adrenalectomy was performed. After 21 days recovery period, Control and Experimental groups were sacrificed under Ketamin HCi anesthesia and clinical and histological observations were made. Microscopic findings, revealed significant changes in adrenalectomized rats. Hypertrophy and thickness of gingival epitelium was apparent in the gingival epithelium of ADX group. Increase in mitotic activity in stratum basale layer of gingival epitelium and increase in keratinisaton layer were observed in adrenalectomized rats. A decrease in collagen fibrils and irregularity of papilla was seen in adrenalectomized rats. Our findings demonstrate the importance of adrenal glands in the development of gingival tissue and suggest that adrenal glands deficiency is one mechanism, by which gingival disorder susceptibility may be increased. © Medwell Journals, 2009.Öğe The prevelance and etiology of dental trauma among 5-72 months preschool children in South-Eastern Anatolia, Turkey(2009) Tumen E.C.; Adiguzel O.; Kaya S.; Uysal E.; Yavuz I.; Atakul F.The main objective of this study was to assess the epidemiology of traumatic dental injuries to the primary teeth in children from 5 to 72 months, all atendees in 11 public nursery schools in South-Eastern Anatolia, Turkey. A total of 657 children (346 boys and 311 girls) of both sexes participated in the study. Traumatic dental injuries were classified according to the modified classification proposed by Ellis. An interview was carried out by two trained and calibrated examiners, and clinical oral examinations included distribution of dental injuries by age and sex, etiology of dental trauma, prevelance of affected teeth and type of damage. All results were analyzed using the Statistical Package for Social Sciences (SPSS) software, version 15.0. The prevalence of traumatic dental injuries was 5.02%. There was greater involvement of boys (78.8%), of children aged 37-48 months (63.63%) and of the maxillary central incisors (92.68%). Falls were more often the etiology for dental injuries (66.7%). Most children with a traumatic dental injuries experienced traumatic injuries to one tooth (3.81%), while 1.21% had two traumatized teeth and 94.9% had no traumatic dental injuries. The most common crown fracture was in enamel only (65.9%), followed by discoloration teeth (14.6%). The prevalence of dental injuries in Turkish preschool children was very low. The present study findings emphasize the importance of encouraging parents to visit the dentist with their child at an early stage. Moreover, traumatic dental injury is widespread in the population; it has both physical and psychological effects, it is treatable; and, most importantly, it is preventable.Öğe Sustainable soundscape: A field study in the historical Suriçi area of Diyarbakir(The Institute of Noise Control Engineering of the USA, Inc., 2015) Aydin D.Ç.; Uysal E.; Akça Y.B.Ö.Various studies have been carried out regarding perceptions of sounds capes in cities or large public spaces. Most sounds cape studies outline the considerable importance of the informational properties of sound, along with its physical characteristics. This study was conducted to investigate the sounds cape preferences of the sonic environment of the historical Suriçi area of Diyarbakir. The Suriçi area has been at the center of many civilizations and cultures over thousands of years. This area includes a number of noisy activities including traditional craft operations such as coppersmiths, blacksmiths and stove manufacturers. Soundscape methodology and analysis techniques have been used in this study to determine the effects of the soundmarks associated with these traditional craft manufacturers. Binaural recordings were conducted in addition to questionnaires. Participants who were questioned were residents of the city. The results imply that, despite the high sound pressure levels, residents responded positively to these sound marks. From these results it can be stated that the special sound marks of a city must be acknowledged as part of the cultural heritage functioning in a sustainable living environment. © 2015 by ASME.
