Fast calibration with compressed sensing using alternating direction method of multipliers in magnetic particle imaging
(IEEE, 2018)Magnetic Particle Imaging (MPI) is a new imaging modality that is used for imaging the spatial distribution of superparamagnetic iron oxide nanoparticles injected as tracers. Image reconstruction in MPI can be realized ... -
Fast system calibration with coded calibration scenes for magnetic particle imaging
(IEEE, 2019)Magnetic particle imaging (MPI) is a relatively new medical imaging modality, which detects the nonlinear response of magnetic nanoparticles (MNPs) that are exposed to external magnetic fields. The system matrix (SM) method ... -
Faz döngülü bSSFP görüntülemede T1 ve T2 haritalamaya parametre tahmini yaklaşımı
(IEEE, 2018)Faz döngülü dengeli kararlı-durum serbest devinim (bSSFP) sinyali eliptik sinyal modeline sahip olduğundan, T1 ve T2 relaksasyon zamanları tek bir faz döngülü bSSFP sekansından tahmin edilebilmektedir. Modelin parametreleri ... -
Fearful faces do not lead to faster attentional deployment in individuals with elevated psychopathic traits
(Springer New York LLC, 2017)In the current study, a gaze-cueing experiment (similar to Dawel et al. 2015) was conducted in which the predictivity of a gaze-cue was manipulated (non-predictive vs highly predictive). This was done to assess the degree ... -
Feasibility of 3-dimensional sampling perfection with application optimized contrast sequence in the evaluation of patients with hydrocephalus
(Lippincott Williams and Wilkins, 2015)Purpose This study aimed to investigate the effectiveness and additive value of T2W 3-dimensional sampling perfection with application optimized contrast (3D-SPACE) with variant flip-angle mode in imaging of all types of ... -
Feedforward and feedback processes in vision
(Frontiers Research Foundation, 2015)[No abstract available] -
Fully automated gridding reconstruction for non-Cartesian x-space magnetic particle imaging
(IOP, 2019)Magnetic particle imaging (MPI) is a fast emerging biomedical imaging modality that exploits the nonlinear response of superparamagnetic iron oxide (SPIO) nanoparticles to image their spatial distribution. Previously, ... -
Full‐brain coverage and high‐resolution imaging capabilities of passband b‐SSFP fMRI at 3T
(Wiley‐Liss, Inc., 2008)Passband balanced-steady-state free precession (b-SSFP)fMRI is a recently developed method that utilizes the passband(flat portion) of the b-SSFP off-resonance response to measureMR signal changes elicited by changes in ... -
Functional characterization of Des-IGF-1 action at excitatory synapses in the CA1 region of rat hippocampus
(American Physiological Society, 2005)Insulin-like growth factor-1 (IGF-1) and growth hormone play a major role in the growth and development of tissues throughout the mammalian body. Plasma IGF-1 concentrations peak during puberty and decline with age. We ... -
Functional subdomains within scene-selective cortex: parahippocampal place area, retrosplenial complex, and occipital place area
(Society for Neuroscience, 2016)Functional MRI studies suggest that at least three brain regions in human visual cortex-the parahippocampal place area (PPA), retrosplenial complex (RSC), and occipital place area (OPA; often called the transverse occipital ... -
Gene expression changes in aging zebrafish (Danio rerio) brains are sexually dimorphic
(BioMed Central, 2014)Background: Brain aging is a multi-factorial process due to both genetic and environmental factors. The zebrafish has recently become a popular model organism for examining aging and age-related diseases because as ... -
Generation of chimeric "aBS nanohemostat" complex and comparing its histomorphological in vivo effects to the traditional ankaferd hemostat in controlled experimental partial nephrectomy model
(Hindawi, 2013)Purpose. Using the classical Ankaferd Blood Stopper (ABS) solution to create active hemostasis during partial nephrectomy (PN) may not be so effective due to insufficient contact surface between the ABS hemostatic liquid ... -
Genetic logic gates enable patterning of amyloid nanofibers
(WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2019)Distinct spatial patterning of naturally produced materials is observed in many cellular structures and even among communities of microorganisms. Reoccurrence of spatially organized materials in all branches of life is ... -
Growth and differentiation of prechondrogenic cells on bioactive self-assembled peptide nanofibers
(American Chemical Society, 2013)Restoration of cartilage defect remains a challenge, as the current treatments are ineffective to return tissue to its health. Thus, developing therapies for treatment of cartilage tissue damage caused by common joint ... -
Growth factor binding on heparin mimetic peptide nanofibers
(American Chemical Society, 2012)Immobilization of growth factors in scaffolds is important for controlling their dose and bioactivity for regenerative medicine applications. Although numerous covalent and noncovalent immobilization strategies have been ... -
Growth hormone and insulin-like growth factor-I alter hippocampal excitatory synaptic transmission in young and old rats
(Age Company, 2013)In rats, as in humans, normal aging is characterized by a decline in hippocampal-dependent learning and memory, as well as in glutamatergic function. Both growth hormone (GH) and insulin-like growth factor-I (IGF-I) levels ... -
Growth hormone modulates hippocampal excitatory synaptic transmission and plasticity in old rats
(Elsevier, 2012)Alterations in the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptor (AMPA-R) and N-methyl-D-aspartate receptor (NMDA-R) have been documented in aged animals and may contribute to changes in hippocampal-dependent ... -
Hadamard slice encoding for reduced-FOV diffusion-weighted imaging
(John Wiley & Sons, 2014)Methods: A 2D echo-planar RF pulse and matching multiband refocusing RF pulses were designed using the Shinnar-Le Roux algorithm to reduce band interference, and variable-rate selective excitation to shorten the pulse ... -
Hemifield asymmetry in the potency of exogenous auditory and visual cues
(Elsevier, 2011)Neurologically normal subjects misperceive the midpoints of lines (PSE) as reliably leftward of veridical center, a phenomenon known as pseudoneglect. This leftward bias reflects the dominance of the right cerebral hemisphere ... -
Heparin mimetic peptide nanofibers promote angiogenesis
(Biomacromolecules, 2011)New blood vessel formation (angiogenesis) is one of the most important processes required for functional tissue formation. Induction of angiogenesis is usually triggered by growth factors released by cells. Glycosaminoglycans ...
