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 ... -
Short-term dietary restriction in old zebrafish changes cell senescence mechanisms
(Elsevier, 2016-10)Brain aging is marked by a decline in cognitive abilities and associated with neurodegenerative disorders. Recent studies have shown, neurogenesis continues into adulthood but is known to be decreasing during advancing age ... -
Size aftereffect is non-local
(Elsevier, 2020)It is well known that prolonged exposure to a certain size stimulus alters the perceived size of a subsequently presented stimulus at the same location. How the rest of the visual space is affected by this size adaptation, ... -
Size-controlled conformal nanofabrication of biotemplated three-dimensional TiO2 and ZnO nanonetworks
(Nature, 2013)A solvent-free fabrication of TiO2 and ZnO nanonetworks is demonstrated by using supramolecular nanotemplates with high coating conformity, uniformity, and atomic scale size control. Deposition of TiO2 and ZnO on ... -
Slow release and delivery of antisense oligonucleotide drug by self-assembled peptide amphiphile nanofibers
(American Chemical Society, 2011)Antisense oligonucleotides provide a promising therapeutic approach for several disorders including cancer. Chemical stability, controlled release, and intracellular delivery are crucial factors determining their efficacy. ... -
SNR dependence of optimal parameters for apparent diffusion coefficient measurements
(IEEE, 2011)Optimizing the diffusion-weighted imaging (DWI) parameters (i.e., the b -value and the number of image averages) to the tissue of interest is essential for producing high-quality apparent diffusion coefficient (ADC) maps. ... -
Spatial learning and memory deficits after whole-brain irradiation are associated with changes in nmda receptor subunits in the hippocampus
(Radiation Research Society., 2006)Whole-brain irradiation is used for the treatment of brain tumors, but can it also induce neural changes, with progressive dementia occurring in 20–50% of long-term survivors. The present study investigated whether 45 Gy ... -
Spatially informed voxelwise modeling for naturalistic fMRI experiments
(Elsevier, 2019)Voxelwise modeling (VM) is a powerful framework to predict single voxel responses evoked by a rich set of stimulus features present in complex natural stimuli. However, because VM disregards correlations across neighboring ... -
Spectrally selective imaging with wideband balanced steady-state free precession MRI
(John Wiley and Sons Inc., 2016)Purpose Unwanted, bright fat signals in balanced steady-state free precession sequences are commonly suppressed using spectral shaping. Here, a new spectral-shaping method is proposed to significantly improve the uniformity ...
