Öğe Effect of melatonin and atenolol on carbon monoxide cardiotoxicity(Blackwell Publishing, 2006) Mizrak, B; Celbis, O; Parlakpinar, H; Ölmez, EThe aim of this study was to define the characteristics of heart rates and myocardial changes in rats exposed to carbon monoxide (CO), and the effects of reoxygenation, atenolol (a beta-blocker) and melatonin after sublethal CO intoxication. Widespread use of beta-blockers in cardiology practice and growing literature on the positive effect of melatonin in ischaemia reperfusion lead us to question their effects in case of CO intoxication. Rats were exposed to CO. After sublethal intoxication the rats were reoxygenated with ambient air. Subsequently blood values, electrocardiographic recordings and pathological changes were examined for each groups. Five rats died after CO intoxication in the control group: no myocardial changes were seen in light microscopy However, myocardium of seven reoxygenated rats presented contraction bands. Seven reoxygenated rats pretreated with atenotol had a higher number of contraction bands of myocardial cells. Seven reoxygenated rats pretreated with melatonin had more contraction bands than reoxygenated rats. and heart rate recordings of these animals revealed a profund and sustained bradycardia. Thus, melatonin and atenolol appear to have some adverse effects in CO intoxication on the myocardial cells.Öğe Estimation of stature and determination of sex from radial and ulnar bone lengths in a Turkish corpse sample(Elsevier Ireland Ltd, 2006) Celbis, O; Agritmis, HDetermination of sex and estimation of stature are important aspects of forensic identification of an unknown individual. In the absence of pelvis the sex is assessed from long bones and cranium as they both provide high accuracy in sexing. The present study is an attempt to assess sex and stature from long bones of the forearm using recently deceased forensic cases in Istanbul, Turkey. The sample is composed of 80 males and 47 females with an average age of 36 and 30 years, respectively. Length measurements from the radius and ulna were obtained by exposing the epiphyseal ends of the long bones in a fashion similar to dry long bones. Discriminant function statistics showed a sex determination accuracy as high as 96%. Regression analysis was used in stature estimation from these two bones. Ideally osteological remains are necessary to make standards for osteological identification. These materials are not always easy to obtain and those available seem to be less ideal when they do not represent a current population. Forensic anthropologists therefore should develop techniques that utilize autopsy remains. (c) 2005 Elsevier Ireland Ltd.

In this article, the evolution and current legal procedures regarding forensic autopsies with emphasis on current legal procedures following the declaration of Turkish Republic in 1923 are delineated.Öğe Forearm bones and sexual variation in humans(Elsevier Sci Ireland Ltd, 2003) Celbis, O; Uzun, I; Iscan, MY[Abstract Not Available]Öğe Manner of death: Could cultural factors account for the differences between the US and Turkish populations(Elsevier Sci Ireland Ltd, 2003) Wright, RK; Celbis, O; Iscan, MY[Abstract Not Available]Öğe Myocardial and electrocardiographic findings in fatal carbon monoxide poisoning: An experimental study(Elsevier Sci Ireland Ltd, 2003) Mizrak, B; Celbis, O; Olmez, E; Iraz, M[Abstract Not Available]Öğe Physical, emotional and sexual violence during pregnancy in Malatya, Turkey(Oxford Univ Press, 2006) Karaoglu, L; Celbis, O; Ercan, C; Ilgar, M; Pehlivan, E; Gunes, G; Genc, MFBackground: In Turkey, violence against women was established as a critical area of concern related to women and various prevention strategies have been developed since 1980. There are limited numbers of studies on violence during pregnancy in the country. This study was performed to determine the prevalence of physical, emotional and sexual violence during pregnancy in Malatya province and the associated factors. Methods: A cross-sectional interview survey was conducted among pregnant women living in Malatya province between October 2003 and May 2004. Stratified probability-proportional-to-size sampling methodology was used for selecting the study population. A total of 824 pregnant women from 60 clusters were studied. Association between violence prevalences and womens' sociodemographic, fertility and behavioural characteristics were evaluated. Results: During pregnancy 31.7% of women were exposed to any form of violence. Emotional violence was the most frequently reported form (26.7%), followed by sexual (9.7%) and physical violence (8.1%). Regular smoking [ odds ratio ( OR) 1.6], unwanted pregnancy (OR 1.8), living in urban area (OR 1.5), low education level of husband (OR 1.7), low family income (OR 1.9) and being in second trimester (OR 1.4) were determined to be the main predictors of overall violence during pregnancy. Conclusions: Violence during pregnancy is a common public health problem in Malatya. Low education level in partners, low family income, husband's unemployment, urban settlement, unwanted pregnancy and smoking should alert health staff towards violence at pregnancy and training of health personnel on the subject is recommended.Öğe An unusual complication of septorhinoplasty -: Massive subarachnoid hemorrhage(Lippincott Williams & Wilkins, 2004) Koçak, A; Gürlek, A; Kutlu, R; Celbis, O; Aydin, NESeptorhinoplasty is a very common operation in the practice of plastic surgery and otolaryngology. We report a case with massive subarachnoid hemorrhage originating from carotid artery injury, following corrective septorhinoplasty. The carotid rupture is a very rare but life-threatening, major complication of nasal surgery. Therefore, surgeons performing surgery in this area should be very careful and aware of this entity. According to our knowledge, this is the fourth case report of a carotid artery injury following septorhinoplasty, but it is the first bilateral and lethal one in the literature.
