Biased competition in semantic representation during natural visual search
(Elsevier, 2020)Humans divide their attention among multiple visual targets in daily life, and visual search can get more difficult as the number of targets increases. The biased competition hypothesis (BC) has been put forth as an ... -
Bioactive self-assembled peptide nanofibers for corneal stroma regeneration
(Elsevier, 2014)Defects in the corneal stroma caused by trauma or diseases such as macular corneal dystrophy and keratoconus can be detrimental for vision. Development of therapeutic methods to enhance corneal regeneration is essential ... -
Bioactive supramolecular peptide nanofibers for regenerative medicine
(Wiley, 2014)Recent advances in understanding of cell-matrix interactions and the role of the extracellular matrix (ECM) in regulation of cellular behavior have created new perspectives for regenerative medicine. Supramolecular peptide ... -
Biocompatible electroactive tetra (aniline)-conjugated peptide nanofibers for neural differentiation
(American Chemical Society, 2018)Peripheral nerve injuries cause devastating problems for the quality of patients' lives, and regeneration following damage to the peripheral nervous system is limited depending on the degree of the damage. Use of ... -
Bone-like mineral nucleating peptide nanofibers induce differentiation of human mesenchymal stem cells into mature osteoblasts
(American Chemical Society, 2014)A bone implant should integrate to the tissue through a bone-like mineralized interface, which requires increased osteoblast activity at the implant-tissue boundary. Modification of the implant surface with synthetic ... -
Border ownership selectivity in human early visual cortex and its modulation by attention
(Society for Neuroscience, 2009)Natural images are usually cluttered because objects occlude one another. A critical aspect of recognizing these visual objects is to identify the borders between image regions that belong to different objects. However, ... -
BSSFP görüntülemede eliptik sinyal modeline dayali eşzamanlı parametre tahmini
(IEEE, 2018)Faz döngülü dengeli kararlı-durum serbest devinim (bSSFP) görüntüleme tekniginde, görüntüde oluşan rezonans dışı frekanslardan kaynaklı sinyal düşüşlerinin uzamsal konumunu kaydırmak amacıyla her çekimde RF darbelerinin ... -
Caloric restriction eliminates the aging-related decline in NMDA and AMPA receptor subunits in the rat hippocampus and induces homeostasis
(ElsevierAysel Sabuncu Brain Research Center (BAM), 2007)Caloric restriction (CR) extends life span and ameliorates the aging-related decline in hippocampal-dependent cognitive function. In the present study, we compared subunit levels of NMDA and AMPA types of the glutamate ... -
Cartilage endplate thickness variation measured by ultrashort echo-time MRI is associated with adjacent disc degeneration
(Lippincott Williams & Wilkins, 2018)Study design: A magnetic resonance imaging study of human cadaver spines. Objective: To investigate associations between cartilage endplate (CEP) thickness and disc degeneration. Summary of background data: Damage to the ... -
Category-selective top-down modulation in the fusiform face area of the human brain during visual search
(IEEE, 2017)Several regions in the ventral-temporal cortex of the human brain are thought to have representations of specific categories of objects. Furthermore, a distributed network of frontal and parietal brain regions is implicated ... -
Cell penetrating peptide amphiphile integrated liposomal systems for enhanced delivery of anticancer drugs to tumor cells
(Royal Society of Chemistry, 2013)Liposomes have been extensively used as effective nanocarriers, providing better solubility, higher stability and slower release of drugs compared to free drug administration. They are also preferred due to their nontoxic ... -
Cholinergic receptor nicotinic alpha 5 (CHRNA5) RNAi is associated with cell cycle inhibition, apoptosis, DNA damage response and drug sensitivity in Breast cancer
(Public Library of Science, 2018)Cholinergic Receptor Nicotinic Alpha 5 (CHRNA5) is an important susceptibility locus for nicotine addiction and lung cancer. Depletion of CHRNA5 has been associated with reduced cell viability, increased apoptosis and ... -
Chronic pain and selective attention to pain arousing daily activity pictures : evidence from an eye tracking study
(Iran University of Medical Sciences, 2017)Introduction: According to the pain research literature, attentional bias for pain is the mechanism responsible for the development and maintenance of fear of pain in patients with chronic pain. However, there is still ... -
Collagen peptide presenting nanofibrous scaffold for intervertebral disc regeneration
(American Chemical Society, 2019)Lower back pain (LBP) is a prevalent spinal symptom at the lumbar region of the spine, which severely effects quality of life and constitutes the number one cause of occupational disability. Degeneration of the intervertebral ... -
Comparing the response modulation hypothesis and the integrated emotions system theory: the role of top-down attention in psychopathy
(Elsevier, 2018)Objective Two major etiological theories on psychopathy propose different mechanisms as to how emotional facial expressions are processed by individuals with elevated psychopathic traits. The Response Modulation Hypothesis ... -
Comparison of system-matrix-based and projection-based reconstructions for field free line magnetic particle imaging
(Infinite Science Publishing, 2017)In magnetic particle imaging (MPI), system sensitivity can be enhanced by scanning the sample along a field free line (FFL) instead of a field free point (FFP). FFL MPI data can then be processed via system-matrix or ... -
Context-dependent lightness affects perceived contrast
(Elsevier Ltd, 2016)Perceived contrast of a grating varies with its background (or mean) luminance: of the two gratings with the same photometric contrast the one on higher luminance background appears to have higher contrast. Does perceived ... -
Contrast affects fMRI activity in middle temporal cortex related to center-surround interaction in motion perception
(Frontiers Research Foundation, 2016)As the size of a high contrast drifting Gabor patch increases, perceiving its direction of motion becomes harder. However, the same behavioral effect is not observed for a low contrast Gabor patch. Neuronal mechanisms ... -
Cooperative effect of heparan sulfate and laminin mimetic peptide nanofibers on the promotion of neurite outgrowth
(Elsevier, 2012)Extracellular matrix contains an abundant variety of signals that are received by cell surface receptors contributing to cell fate, via regulation of cellular activities such as proliferation, migration and differentiation. ...
