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 ... -
Homozygosity mapping and targeted genomic sequencing reveal the game responsible for cerebellar hypoplasia and quadrupedal locomotion in a consanguineous kindred
(Cold Spring Harbor Laboratory Press, 2011)The biological basis for the development of the cerebro-cerebellar structures required for posture and gait in humans is poorly understood. We investigated a large consanguineous family from Turkey exhibiting an extremely ... -
Homozygous LAMC3 mutation links to structural and functional changes in visual attention networks
(Elsevier, 2019)The occipital lobe contains a substantial part of the neural machinery involved in visual perception. Mutations in the LAMC3 gene have recently been shown to cause complex bilateral occipital cortical gyration abnormalities. ... -
Huber function based reconstruction in accelerated phase-cycled bSSFP acquisitions for increased detection performance
(IEEE, 2017)Balanced steady-state free precession imaging suffers from irrecoverable signal losses, called banding artifacts. A common way to alleviate banding artifacts without sacrificing scan-efficiency is to use multiple-acquisition ... -
Human and machine learning in non- markovian decision making
(Public Library of Science, 2015)Humans can learn under a wide variety of feedback conditions. Reinforcement learning (RL), where a series of rewarded decisions must be made, is a particularly important type of learning. Computational and behavioral ... -
Imaging and surgical outcomes of spinal tumors in 18 dogs and one cat
(The Korean Society of Veterinary Science., 2016)Clinical and magnetic resonance imaging (MRI) findings, histological appearances and surgical outcomes of 18 dogs and one cat with spinal tumors are presented. Medical records of the cases admitted for spinal disorders ... -
Improving pancreatic islet in vitro functionality and transplantation efficiency by using heparin mimetic peptide nanofiber gels
(Elsevier, 2015)Pancreatic islet transplantation is a promising treatment for type 1 diabetes. However, viability and functionality of the islets after transplantation are limited due to loss of integrity and destruction of blood vessel ... -
Incorporating family function into chronic pain disability: the role of catastrophizing
(Hindawi Publishing Corporation, 2016)Background: Observers' responses to pain are recently investigated to more comprehensively explain chronic pain (CP) and disability. However, the role of family context, defined as interference in roles, communication, and ... -
Informed feature regularization in voxelwise modeling for naturalistic fMRI experiments
(Wiley, 2020-04-21)Voxelwise modeling is a powerful framework to predict single‐voxel functional selectivity for the stimulus features that exist in complex natural stimuli. Yet, because VM disregards potential correlations across stimulus ... -
Integrated assessment of visual perception abnormalities in psychotic disorders and relationship with clinical characteristics
(Cambridge University Press, 2019)Background-The visual system is recognized as an important site of pathology and dysfunction in schizophrenia. In this study, we evaluated different visual perceptual functions in patients with psychotic disorders using a ... -
Interpretability analysis for Turkish word embeddings
(IEEE, 2018)Kelime temsilleri, doğal dil işleme (DDİ) uygulamalarında sağladıkları önemli performans artışları dolayısıyla günümüzde yaygın olarak çalışılmakta ve kullanılmaktadır. Kelime temsili öğrenen algoritmalar, etiketsiz büyük ... -
Intracellular accumulation of gold nanoparticles leads to inhibition of macropinocytosis to reduce the endoplasmic reticulum stress
(Nature Publishing Group, 2017)Understanding the toxicity of nanomaterials remains largely limited to acute cellular response, i.e., short-Term in vitro cell-death based assays, and analyses of tissue-and organ-level accumulation and clearance patterns ... -
Intrathecal Gadolinium-Enhanced MR Cisternography: A Comprehensive Review
(American Society of Neuroradiology, 2013)CE-MRC has been in use for the past 15 years and was reported to be a useful method in the evaluation of CSF disorders and hydrocephalus. The use of CE-MRC in conjunction with other MR imaging techniques has been shown to ... -
Investigation of Heschl's gyrus and planum temporale in patients with schizophrenia and bipolar disorder: a proton magnetic resonance spectroscopy study
(Elsevier, 2015)Background: Superior temporal cortices include brain regions dedicated to auditory processing and several lines of evidence suggest structural and functional abnormalities in both schizophrenia and bipolar disorder within ... -
The involvement of centralized and distributed processes in sub-second time interval adaptation: an ERP investigation of apparent motion
(Blackwell Publishing Ltd, 2017)Accumulating evidence suggests that the timing of brief stationary sounds affects visual motion perception. Recent studies have shown that auditory time interval can alter apparent motion perception not only through ... -
Is there a common factor for vision?
(ARVO, 2014)Abstract In cognition, common factors play a crucial role. For example, different types of intelligence are highly correlated, pointing to a common factor, which is often called g. One might expect that a similar common ... -
Iterative H-minima-based marker-controlled watershed for cell nucleus segmentation
(John Wiley & Sons, Inc., 2016)Automated microscopy imaging systems facilitate high-throughput screening in molecular cellular biology research. The first step of these systems is cell nucleus segmentation, which has a great impact on the success of the ... -
Label-free nanometer-resolution imaging of biological architectures through surface enhanced raman scattering
(Nature Publishing Group, 2013)Label free imaging of the chemical environment of biological specimens would readily bridge the supramolecular and the cellular scales, if a chemical fingerprint technique such as Raman scattering can be coupled with super ...
