Publication Metadata only Farlateral approach and determaniton unilateral stabilization criteria for lesions located anterior to C1-2 in the craniocervical region: Cadaver study(2022-09-23) GÜVENÇ, YAHYA; VERİMLİ, URAL; BIYIKLI, ERHAN; GÜVENÇ Y., TOPAL B., VERİMLİ U., BIYIKLI E.Publication Metadata only Morphometric characteristics of caudal cranial nerves at petroclival region in fetuses(SPRINGER, 2016) ÖZKAN, MAZHAR; Ozdogmus, Omer; Saban, Enis; Ozkan, Mazhar; Yildiz, Sercan Dogukan; Verimli, Ural; Cakmak, Ozgur; Arifoglu, Yasin; Sehirli, UmitMorphometric measurements of cranial nerves in posterior cranial fossa of fetus cadavers were carried out in an attempt to identify any asymmetry in their openings into the cranium. Twenty-two fetus cadavers (8 females, 14 males) with gestational age ranging between 22 and 38 weeks (mean 30 weeks) were included in this study. The calvaria were removed, the brains were lifted, and the cranial nerves were identified. The distance of each cranial nerve opening to midline and the distances between different cranial nerve openings were measured on the left and right side and compared. The mean clivus length and width were 21.2 +/- A 4.4 and 13.2 +/- A 1.5 mm, respectively. The distance of the twelfth cranial nerve opening from midline was shorter on the right side when compared with the left side (6.6 +/- A 1.1 versus 7.1 +/- A 0.8 mm, p = 0.038). Openings of other cranial nerves did not show such asymmetry with regard to their distance from midline, and the distances between different cranial nerves were similar on the left and right side. Cranial nerves at petroclival region seem to show minimal asymmetry in fetuses.Publication Metadata only The high 2D:4D finger length ratio effects on atherosclerotic plaque development(ELSEVIER IRELAND LTD, 2010) ÖZDOĞMUŞ, NECMETTİN ÖMER; Ozdogmus, Omer; Cakmak, Yusuf Oezguer; Coskun, Murat; Verimli, Ural; Cavdar, Safiye; Uzun, IbrahimBackground: The index finger to ring finger length ratio (2D:4D) of the right hand are affected by prenatal testosterone levels in male. To date, it has been determined that the high 2D: 4D ratio is related to the myocardial infarction, however no research has revealed the relationship between the high 2D: 4D ratio whose coronary artery shows atherosclerotic plaque development. Objective: The aim of this study was to display the relationship between the 2D: 4D ratio and atherosclerosis formation in male autopsy cases. Methods: We designed a study in 100 heterosexual male autopsies whose mean age was 21.4 +/- 2.47 (range between 17 and 25). The 2nd and 4th digits were measured on the palmar surface of the right hand and taken the right coronary artery to show the atherosclerotic plaque development. Results and conclusion: Grade 3 group had significantly higher 2D: 4D ratio compared to Grade 1 and Grade 2 groups (p = 0.02 for both). (C) 2009 Elsevier Ireland Ltd.

S., VERİMLİ U.; Balcı, Akın Eraslan; Yüksel, MustafaPublication Metadata only The Effect of early active Movement following Repair of Extensor Tendons in Zone IV using three different suture Techniques - A cadaveric Study(THIEME MEDICAL PUBL INC, 2021) VERİMLİ, URAL; Zeynalov, Samir Ilgaroglu; Ismailoglu, Abdulveli; Verimli, Ural; Alakbarov, Anar; Cansu, ErenZusammenfassungPublication Open Access A rare case: variation in the third part of the axillary artery(2022-08-01) VERİMLİ, URAL; Ongun B. C. , VERİMLİ U., Yalin A., Sehirli S. U.Axillary artery branching pattern variations are commonly observed during routine dissections. These variations have great importance due to the wide range of therapeutic and diagnostic procedures carried out in the axillary region. Therefore, neurovascular abnormalities should be well-known before surgeries involving the axillary region in order to prevent complications. This case report presents a common trunk at the third part of the axillary artery which gives rise to the deep brachial artery.Publication Metadata only Volumetric properties of paranasal sinuses in thin-section craniofacial computedtomography images using interactive segmentation method(2021-09-01) VERİMLİ, URAL; ÇİMŞİT, NURİ ÇAGATAY; BUĞDAYCI, ONUR; SANCAKLI B., VERİMLİ U., BUĞDAYCI O., ÇİMŞİT N. Ç.Aim: The aim of this study is to examine the volumetric properties of the paranasal sinuses by creating threedimensional reconstructions of high-resolution images obtained by computed tomography by interactive segmentation method. Material and Methods: Thin-section multidetector computed tomography images of 40 female and 40 male individuals between the ages of 20-40 without cranium pathology will be evaluated retrospectively. The volumetric characteristics of the paranasal sinuses will be evaluated in terms of the age and gender of the sample group. The observed variations and mucosal thickness changes in the sinus walls will be determined. Computed Tomography images were transferred to the Imfusion Suite Demo software and volume measurement was performed separately for the right and left by segmentation method. Results: In our study, a statistically significant difference was observed between male individuals for sphenoidal sinus (p=0.0354), and a gender-related difference was observed for frontal sinus (p=0.0033) and maxillaris sinus (p=0.0104) in the same age group. Conclusion: Eventually we aim to obtain comprehensive morphometric information for paranasal sinuses and provide crucial information for clinical applications. Measurement, examination and analysis of paranasal sinus volumes are expected to reduce time required and benefit the anatomical outcomes for certain surgical interventions.Publication Metadata only Glutamic acid decarboxylase isoform distribution in transgenic mouse septum: an anti-GFP immunofluorescence study(SPRINGER, 2016) ŞEHİRLİ, ÜMİT SÜLEYMAN; Verimli, Ural; Sehirli, Umit S.The septum is a basal forebrain region located between the lateral ventricles in rodents. It consists of lateral and medial divisions. Medial septal projections regulate hippocampal theta rhythm whereas lateral septal projections are involved in processes such as affective functions, memory formation, and behavioral responses. Gamma-aminobutyric acidergic neurons of the septal region possess the 65 and 67 isoforms of the enzyme glutamic acid decarboxylase. Although data on the glutamic acid decarboxylase isoform distribution in the septal region generally appears to indicate glutamic acid decarboxylase 67 dominance, different studies have given inconsistent results in this regard. The aim of this study was therefore to obtain information on the distributions of both of these glutamic acid decarboxylase isoforms in the septal region in transgenic mice. Two animal groups of glutamic acid decarboxylase-green fluorescent protein knock-in transgenic mice were utilized in the experiment. Brain sections from the region were taken for anti-green fluorescent protein immunohistochemistry in order to obtain estimated quantitative data on the number of gamma-aminobutyric acidergic neurons. Following the immunohistochemical procedures, the mean numbers of labeled cells in the lateral and medial septal nuclei were obtained for the two isoform groups. Statistical analysis yielded significant results which indicated that the 65 isoform of glutamic acid decarboxylase predominates in both lateral and medial septal nuclei (unpaired two-tailed t-test p < 0.0001 for LS, p < 0.01 for MS). This study is the first to reveal the dominance of glutamic acid decarboxylase isoform 65 in the septal region in glutamic acid decarboxylase-green fluorescent protein transgenic mice.Publication Open Access Morphometric analysis of middle and posterior cranial fossae foramina in 3d reconstructions of ct images: A midline asymmetry evaluation(2022-01-01) VERİMLİ, URAL; BUĞDAYCI, ONUR; BEKİROĞLU, GÜLNAZ NURAL; VERİMLİ U., BUĞDAYCI O., Yildiz S. D., Ozkilic E., BEKİROĞLU G. N., ÖZDOĞMUŞ N. Ö.Objective: The cranial base harbours numerous foramina, and the anatomical properties of the foramina are crucial in clinical interventions. The purpose of the current study is to evaluate possible asymmetries regarding the middle and posterior cranial fossae foramina using 3D reconstructions of high-resolution computed tomography (CT) images. Patients and Methods: High-resolution cranial CT images of 253 female and 287 male adult patients were used in the study. The patients were 18 to 40 years of age without any apparent cranial pathology. The distances from the foramen rotundum, foramen ovale, foramen spinosum, internal acoustic meatus, hypoglossal canal to the midline were measured bilaterally to compare both sides. Results: The foramen spinosum and the mid-clival line measurements demonstrated statistically significant results favoring the right side (p=0.03, right mean 3.052 ± 0.253 cm, left mean 2.982 ± 0.193 cm). In males, the right foramen spinosum to mid-clival line measurements were significantly longer than the left side (p=0.027, right mean 3.150 ± 0.250 cm, left mean 3.070 ± 0.180 cm). Conclusion: As predicted, the male measurements were significantly longer than the female measurements regardless of sides in all measurements. The measurements of cranial asymmetries may help describe anomalies and may contribute to the clinical approachesPublication Metadata only Diagnostic utilities of tracheal ultrasound and USB-endoscope for the confirmation of endotracheal tube placement: A cadaver study(W B SAUNDERS CO-ELSEVIER INC, 2018) DENİZBAŞI ALTINOK, ARZU; Sanri, Erkman; Akoglu, Ebru Unal; Karacabey, Sinan; Verimli, Ural; Akoglu, Haldun; Sehirli, Umit; Denizbasi, ArzuObjectives: Confirmation of the endotracheal tube placement (CoETP) has the utmost importance in the management of an airway. Visualization of tracheal rings or carina with a fiber-optical bronchoscope (FOB) has considered to be a reliable method for the CoETP. However, FOB is expensive, time-consuming, and not always practical. Inexpensive endoscopic USB-cameras were shown to aid intubation successfully and reliably. On the other hand, there have been no studies investigating their use for the CoETP. Tracheal ultrasonography (TUS) is also a new, inexpensive and widely available alternative. A cadaver study has planned to evaluate the diagnostic utility of TUS and a USB-camera. Methods: This study was conducted in the Anatomy Lab of a University on a fresh frozen female cadaver. Three senior Emergency Physicians have intubated the cadaver, and performed TUS or USB-endoscopy. We have prepared a randomized intubation list (n = 96) in three blocks (3 times 32) as to include equal number of esophageal and tracheal intubations (48 for each). Each EP is performed all three interventions (intubation, TUS and USB-endoscopy) in consecutive blocks of 32 intubations, in turn. The position of the tube has been verified from a 2 cm wide ostium on the proximal trachea. Results: In this study, all intubations (n = 96, 100%) were correctly identified as tracheal or esophageal with both TUS and USB-camera. Both the sensitivity and specificity of TUS and USB-endoscopy for the CoETP were 100.0%. Conclusion: The perfect accuracy of TUS and USB-endoscopy, have placed those techniques in a unique position as an alternative in resource-poor situations. (C) 2018 Elsevier Inc. All rights reserved.
