Several studies show that stress reduces Functional Cerebral Asymmetries (FCA) in different species. Since only few studies have evaluated the effect of stress on FCA in dogs, a clear conclusion about the possible impact of stress and FCA has not yet been achieved in dogs. This is what we aim to achieve by using different motor laterality tests. Paw preferences of two groups of dogs (n=27), including chronically stressed and normal ones, were tested within the groups by food reaching (FR) and KongTMtests conducted in home and novel environments. The open field test (OFT) was used to set an acute stress situation and motor laterality tests were conducted following the OFT to determine FCA under acute stress. In both groups, the dogs showed a significant rightward asymmetry (T-test, p≤0.01) in the FR test at home while rightward LI was significantly reduced in the test conducted after the OFT (T-test, p≤0.01). The KongTMtest evinced no statistically significant difference. The preliminary results show that stress reduces rightward functional asymmetry in dogs. This study is the first to demonstrate an increase in the right-hemispheric processing in dogs under acute stress.

Impact of antibiotic induced gut microbiota alteration on cognitive abilities and behaviours of mice Ceylani, Taha; Gözen, Ayşe Gül; Doğru, Ewa; Department of Biology (2018) Recently arising studies with animal models show that there is a bidirectional communication between gut microbiota and central nervous system (CNS) through neural, endocrine and immune pathways which influences brain function and behavior. Apparently, gut microbiota may play a role in the regulation of anxiety, mood, cognition, and pain sensation. Gut microbiota may cause gastrointestinal disorders, such as irritable bowel syndrome (IBS), which can be comorbid with stress-related psychiatric conditions inf...
Comparison of spatial learning in the partially baited radial-arm maze task between commonly used rat strains: Wistar, Spargue-Dawley, Long-Evans, and outcrossed Wistar/Sprague-Dawley Gokcek-Sarac, Cigdem; Wesierska, Malgorzata; Jakubowska-Dogru, Ewa (2015-03-01) Strain-related differences in animals' cognitive ability affect the outcomes of experiments and may be responsible for discrepant results obtained by different research groups. Therefore, behavioral phenotyping of laboratory animals belonging to different strains is important. The aim of the present study was to compare the variation in allothetic visuospatial learning in most commonly used laboratory rat strains: inbred Wistar (W) and Sprague-Dawley (SD), outcrossed Wistar/Sprague-Dawley (W/SD), and outbre...
The relationship of expressed emotion and psychosocial variables with the quality of life of haemodialysis patients : an analysis within the conservation of resources model Yalçınkaya Alkar, Özden; Karancı, Ayşe Nuray; Department of Psychology (2006) This study aimed to examine the quality of life (QOL) and well-being of haemodialysis patients and the relationship of two components of perceived expressed emotion (criticism/hostility and emotional over-involvement) and other psychosocial resources within the Conservation of Resources Model. Demographic variables and haemodialysis related information of patients, classified as resources, were also included in the study. One hundred and six haemodialysis patients voluntarily participated in the study. Befo...
The biomechanical relationship between incisor and condylar guidances in deep bite and normal cases Darendeliler, N; Dincer, M; Soylu, Reşit (Wiley, 2004-05-01) The purpose of this study was to investigate the biomechanical relationship between the condylar and anterior guidances in deep bite malocclusion and control groups. The subjects consisted of 18 deep bite patients and 14 normal occlusions. A four-bar mechanism was described on the lateral cephalogram films and a computer program, for which the lengths of the links measured on the films were the inputs, was developed. The computer program was used to calculate the angles of rotation of the mandible and the c...
Investigating the role of RNA-binding proteins (RBPS) in explaining differential gene expression in cancer Lafzi, Atefeh; Aydın Son, Yeşim; Kazan, Hilal; Department of Bioinformatics (2016) Most of the studies on cancer have tried to explain the observed differential gene expression considering only transcriptional regulation. However, post-transcriptional regulation (PTR) has been increasingly recognized as a complex mechanism that also controls various steps of gene expression regulation. Post-transcritional regulation is governed by the interactions of RNA-binding proteins (RBPs) and microRNAs (miRNAs) with their target genes. In this thesis, having found that several RBPs are differentiall...
