FUNCTIONAL IMAGING OF MATRIX STRUCTURE OF CRYOPRESERVED ENGINEERED TISSUES USING BACK-DIRECTIONAL GATED MESOSCOPIC IMAGING

FUNCTIONAL NETWORKS OF ANATOMIC BRAIN REGIONS Velioglu, Burak; Aksan, Emre; Onal, Itir; Firat, Orhan; Ozay, Mete; Yarman Vural, Fatoş Tunay (2014-08-20) In this study, we propose a new approach to construct a two-level functional brain network. The nodes of the first-level network are the voxels of the functional Magnetic Resonance Images (tMRI) recorded during an object recognition task. The nodes of the network at the second-level are the anatomic regions of the brain. The arcs of the first level are estimated by a linear regression equation for the meshes formed around each voxel. Neighbors of each voxel are determined by using a functional similarity me...
Functional characterization of two potential breast cancer related genes Akhavantabasi, Shiva; Erson Bensan, Ayşe Elif; Department of Biology (2012) Cancer may arise as a result of deregulation of oncogenes and/or tumor suppressors. Although much progress has been made for the identification of such cancer related genes, our understanding of the complex tumorigenesis pathways is still not complete. Therefore, to improve our understanding of how certain basic mechanisms work in normal and in cancer cells, we aimed to characterize two different breast cancer related genes. First part of the study focused on subcellular localization USP32 (Ubiquitin Specif...
Functional regeneration of glossopharyngeal nerve through micromachined sieve electrode arrays Bradley, Robert M.; Smoke, Richard H.; Akın, Tayfun; Najafi, Khalil (Elsevier BV, 1992-10-23) To assess the potential of micromachined silicon sieve electrodes for long term recordings from single afferent sensory fibers, we implanted them between the cut ends of rat glossopharyngeal nerves which innervate taste and somatosensory receptors on the posterior tongue. After the implants had been in place for an average of 101 days nerve regeneration was measured using histological and electrophysiological methods. Axons of the glossopharyngeal nerve regenerated through holes in the sieves and supported ...
Functional Mesh Model with Temporal Measurements for Brain Decoding Onal, Itir; Ozay, Mete; Yarman Vural, Fatoş Tunay (2015-08-29) We propose a method called Functional Mesh Model with Temporal Measurements (FMM-TM) to estimate a functional relationship among voxels using temporal data, and employ these relationships for brain decoding. For each sample, we measure Blood Oxygenation Level Dependent (BOLD) responses from each voxel, and construct a functional mesh around each voxel (called seed voxel) with its nearest neighbors selected using distance metrics namely Pearson correlation, cosine similarity and Euclidean distance. Then, we ...
Functional evaluation of intraarticular severely comminuted fractures of the calcaneus with gait analysis BOZKURT, Murat; Kentel, B. Behzat; Yavuzer, Gunes; Öçgüder, Ali; Heycan, Cengiz; Tönük, Ergin (Elsevier BV, 2004-11-01) Twenty-one patients (23 feet) treated nonsurgically for severely comminuted intraarticular fractures of the calcaneus were evaluated prospectively with a clinical scoring scale and computerized gait analysis. All patients had Sanders type III and type IV fractures. The treatment protocol consisted of no closed reduction, immobilization in removable splint, physiotherapy after edema subsided, and weightbearing after 8 weeks. All patients had a minimum follow-up of 2 years (mean, 38 months). Clinical results ...
