Abnormal subcortical activity in congenital mirror movement disorder with RAD51 mutation
(Turkish Society of Radiology, 2018)PURPOSE Congenital mirror movement disorder (CMMD) is characterized by unintended, nonsuppressible, homologous mirroring activity contralateral to the movement on the intended side of the body. In healthy controls, unilateral ... -
Adaptation to average duration
(Springer New York LLC, 2021)There has been a recent surge of research examining how the visual system compresses information by representing the average properties of sets of similar objects to circumvent strict capacity limitations. Efficient ... -
Advanced preclinical models for evaluation of drug-induced liver injury – consensus statement by the European Drug-Induced Liver Injury Network [PRO-EURO-DILI-NET]
(Elsevier, 2021-06-24)Drug-induced liver injury (DILI) is a major cause of acute liver failure (ALF) and one of the leading indications for liver transplantation in Western societies. Given the wide use of both prescribed and over the counter ... -
Age-related synapse loss in hippocampal CA3 is not reversed by caloric restriction
(Pergamon Press, 2010)Caloric restriction (CR) is a reduction of total caloric intake without a decrease in micronutrients or a disproportionate reduction of any one dietary component. While CR attenuates age-related cognitive deficits in tasks ... -
Aging alters the molecular dynamics of synapses in a sexually dimorphic pattern in zebrafish (Danio rerio)
(Elsevier, 2017-06)The zebrafish has become a popular model for studying normal brain aging due to its large fecundity, conserved genome, and available genetic tools; but little data exists about neurobiological age-related alterations. The ... -
Alkaline phosphatase-mimicking peptide nanofibers for osteogenic differentiation
(American Chemical Society, 2015)Recognition of molecules and regulation of extracellular matrix synthesis are some of the functions of enzymes in addition to their catalytic activity. While a diverse array of enzyme-like materials have been developed, ... -
Amyloid inspired self-assembled peptide nanofibers
(American Chemical Society, 2012)Amyloid peptides are important components in many degenerative diseases as well as in maintaining cellular metabolism. Their unique stable structure provides new insights in developing new materials. Designing bioinspired ... -
Anatomical measurements correlate with individual magnetostimulation thresholds for kHz‐range homogeneous magnetic fields
(Wiley, 2020)Purpose: Magnetostimulation, also known as peripheral nerve stimulation (PNS), is the dominant safety constraint in magnetic resonance imaging (MRI) for the gradient magnetic fields that operate around 0.1–1 kHz, and for ... -
Antigenic GM3 lactone mimetic molecule integrated mannosylated glycopeptide nanofibers for the activation and maturation of dendritic cells
(American Chemical Society, 2017)The ability of dendritic cells to coordinate innate and adaptive immune responses makes them essential targets for vaccination strategies. Presentation of specific antigens by dendritic cells is required for the activation ... -
Aqueous paramagnetic solutions for MRI phantoms at 3 T: a detailed study on relaxivities
(Turkiye Klinikleri Journal of Medical Sciences, 2017)Phantoms with known T1 and T2 values that are prepared using solutions of easily accessible paramagnetic agents are commonly used in MRI imaging centers, especially with the goal of validating the accuracy of quantitative ... -
An arbitrary waveform MPI scanner
(Infinite Science Publishing, 2022)In magnetic particle imaging (MPI) systems, impedance matching or tuning circuitry has to be employed at a particular operating frequency to handle the reactive power. In this work, we propose a drive coil design with a ... -
Assessment of liliequist membrane by 3D-SPACE technique at 3 T
(Springer, 2016)Introduction Liliequist membrane (LM) is the most important anatomic structure for the success of endoscopic third ventriculostomy (ETV). Identification of this membrane is difficult with conventional MRI techniques. ... -
Assessment of third ventriculostomy patency with the 3D-SPACE technique: a preliminary multicenter research study
(American Association of Neurological Surgeons, 2015)Object The goal of this study was to determine the value of the 3D sampling perfection with application-optimized contrasts using different flip-angle evolutions (3D-SPACE) technique in the evaluation of endoscopic third ... -
Association of fine motor loss and allodynia in fibromyalgia: an fNIRS study
(Routledge, 2018)Recent studies showed that fine motor control dysfunction was observed in fibromyalgia (FM) syndrome as well as allodynia. However, brain signatures of this association still remain unclear. In this study, finger tapping ... -
The associations of basic psychological needs and autonomous-related self with time perspective: the cultural and familial antecedents of balanced time perspective
(Elsevier, 2018)Time perspective develops from learning experiences pertaining to family and culture (Zimbardo & Boyd, 1999), however no study specifically examined these factors. The present research examines cultural and familial processes ... -
Attention modulates neuronal correlates of interhemispheric integration and global motion perception
(Association for Research in Vision and Ophthalmology Inc., 2014)In early retinotopic areas of the human visual system, information from the left and right visual hemifields (VHFs) is processed contralaterally in two hemispheres. Despite this segregation, we have the perceptual experience ... -
Attention-dependent representation of a size illusion in human V1
(Cell Press, 2008)One of the most fundamental properties of human primary visual cortex (V1) is its retinotopic organization, which makes it an ideal candidate for encoding spatial properties, such as size, of objects. However, three-dimensional ...
