Recent advances in bioactive 1D and 2D carbon nanomaterials for biomedical applications
(Elsevier, 2018)One-dimensional (1D) carbon nanotubes (CNTs) and the two-dimensional (2D) graphene represent the most widely studied allotropes of carbon. Due to their unique structural, electrical, mechanical and optical properties, 1D ... -
Recessive LAMC3 mutations cause malformations of occipital cortical development
(Nature Publishing Group, 2011)The biological basis for regional and inter-species differences in cerebral cortical morphology is poorly understood. We focused on consanguineous Turkish families with a single affected member with complex bilateral ... -
Reconstruction by calibration over tensors for multi-coil multi-acquisition balanced SSFP imaging
(John Wiley & Sons, 2018)Purpose: To develop a rapid imaging framework for balanced steady-state free precession (bSSFP) that jointly reconstructs undersampled data (by a factor of R) across multiple coils (D) and multiple acquisitions (N). To ... -
Reduced field-of-view diffusion imaging of the human spinal cord: comparison with conventional single-shot echo-planar imaging
(American Society of Neuroradiology, 2011)BACKGROUND AND PURPOSE: DWI of the spinal cord is challenging because of its small size and artifacts associated with the most commonly used clinical imaging method, SS-EPI. We evaluated the performance of rFOV spinal cord ... -
Reduction of the radiofrequency heating of metallic devices using a dual‐drive birdcage coil
(Wiley, 2013)In this work, it is demonstrated that a dual-drive birdcage coil can be used to reduce the radiofrequency heating of metallic devices during magnetic resonance imaging. By controlling the excitation currents of the two ... -
The relationship between ruminating the catastrophic consequences of bodily changes and positive reappraisal and practical problem-solving strategies in individuals with illness anxiety disorder
(Iran University of Medical Sciences, 2020-09)Introduction: Cognitive emotion regulation is suggested to contribute to Illness Anxiety Disorder (IAD). Reappraisal and suppression are essential ER strategies with controversial data about their roles in IAD. Relevant ... -
Relaxation-based color magnetic particle imaging for viscosity mapping
(American Institute of Physics, 2019)Magnetic particle imaging (MPI) uses superparamagnetic iron oxide (SPIO) nanoparticles as biomedical imaging tracers. The potential applications of MPI have recently been broadened by the introduction of “color” MPI ... -
Relaxation-based viscosity mapping for magnetic particle imaging
(Institute of Physics Publishing, 2017)Magnetic particle imaging (MPI) has been shown to provide remarkable contrast for imaging applications such as angiography, stem cell tracking, and cancer imaging. Recently, there is growing interest in the functional ... -
Reply to tzoulis et al.: genetic and clinical heterogeneity of essential tremor
(National Academy of Sciences, 2015)In addressing our recent report of HTRA2 p.G399S as the gene and mutation responsible for essential tremor and subsequent Parkinson disease in a large kindred (1), Tzoulis et al. (2) screened this mutation in patients with ... -
Resting-state network dysconnectivity in ADHD: a system-neuroscience-based meta-analysis
(Taylor and Francis, 2020)Objectives: Neuroimaging studies report altered resting-state functional connectivity in attention deficit/hyperactivity disorder (ADHD) across multiple brain systems. However, there is inconsistency among individual ... -
Selective adhesion and growth of vascular endothelial cells on bioactive peptide nanofiber functionalized stainless steel surface
(Elsevier, 2011)Metal-based scaffolds such as stents are the most preferred treatment methods for coronary artery disease. However, impaired endothelialization on the luminal surface of the stents is a major limitation occasionally leading ... -
Selective adsorption of L1210 leukemia cells/human leukocytes on micropatterned surfaces prepared from polystyrene/polypropylene-polyethylene blends
(Elsevier, 2014)The objective of this study is to prepare polymeric surfaces which will adsorb L1210 leukemia cells selectively more than that of healthy human leukocytes in order to develop new treatment options for people with leukemia. ... -
A self-actuated cellular protein delivery machine
(American Chemical Society, 2019)Engineered bacterial cells have great promise to solve global problems, yet they are hampered by a lack of convenient strategy for controlled protein release. A well-controlled protein translocation through cellular membranes ... -
Self-assembled peptide amphiphile nanofibers and PEG composite hydrogels as tunable ECM mimetic microenvironment
(American Chemical Society, 2015)(Figure Presented). Natural extracellular matrix (ECM) consists of complex signals interacting with each other to organize cellular behavior and responses. This sophisticated microenvironment can be mimicked by advanced ... -
Semantic similarity between Turkish and European languages using word embeddings
(IEEE, 2017)Representation of words coming from vocabulary of a language as real vectors in a high dimensional space is called as word embeddings. Word embeddings are proven to be successful in modelling semantic relations between ... -
Semantic structure and interpretability of word embeddings
(Institute of Electrical and Electronics Engineers, 2018)Dense word embeddings, which encode meanings of words to low-dimensional vector spaces, have become very popular in natural language processing (NLP) research due to their state-of-the-art performances in many NLP tasks. ... -
Set similarity modulates object tracking in dynamic environments
(Springer New York LLC, 2018)Based on the observation that sports teams rely on colored jerseys to define group membership, we examined how grouping by similarity affected observers’ abilities to track a “ball” target passed between 20 colored circle ... -
Short-and long-term forms of neural adaptation: an ERP investigation of dynamic motion aftereffects
(Elsevier, 2020)Adaptation is essential to interact with a dynamic and changing environment, and can be observed on different timescales. Previous studies on a motion paradigm called dynamic motion aftereffect (dMAE) showed that neural ...
