(Shahid Beheshti University of Medical Sciences, 2015)Linear scleroderma “en coup de sabre” is a subset of localized scleroderma with band-like sclerotic lesions typically involving the fronto-parietal regions of the scalp. Patients often present with neurologic symptoms. On ... -
Atypical Sulcal Pattern in Children with Developmental Dyslexia and At-Risk Kindergarteners
(Oxford University Press (OUP), 2015)Developmental dyslexia (DD) is highly heritable and previous studies observed reduced cortical volume, white matter integrity, and functional alterations in left posterior brain regions in individuals with DD. The primary ... -
Atypical visual processing in posttraumatic stress disorder☆
(Elsevier, 2013)Background: Many patients with Posttraumatic Stress Disorder (PTSD) feel overwhelmed in situations with high levels of sensory input, as in crowded situations with complex sensory characteristics. These difficulties might ... -
Audiovisual Interval Size Estimation Is Associated with Early Musical Training
(Public Library of Science, 2016)Although pitch is a fundamental attribute of auditory perception, substantial individual differences exist in our ability to perceive differences in pitch. Little is known about how these individual differences in the ... -
Audit of Early Mortality among Patients Admitted to the General Medical Ward at a District Hospital in Botswana
(Ubiquity Press, Ltd., 2019)Background: Mortality among adult general medical admissions has been reported to be high across sub-Saharan Africa, yet there is a paucity of literature on causes of general medical inpatient mortality and quality-related ... -
Audit-identified avoidable factors in maternal and perinatal deaths in low resource settings: a systematic review
(BioMed Central, 2014)Background: Audits provide a rational framework for quality improvement by systematically assessing clinical practices against accepted standards with the aim to develop recommendations and interventions that target ... -
The Auditory Anatomy of the Minke Whale (Balaenoptera acutorostrata): A Potential Fatty Sound Reception Pathway in a Baleen Whale
(Wiley, 2012)Cetaceans possess highly derived auditory systems adapted for underwater hearing. Odontoceti (toothed whales) are thought to receive sound through specialized fat bodies that contact the tympanoperiotic complex, the bones ... -
Auditory Conflict Resolution Correlates with Medial–Lateral Frontal Theta/Alpha Phase Synchrony
(Public Library of Science, 2014)When multiple persons speak simultaneously, it may be difficult for the listener to direct attention to correct sound objects among conflicting ones. This could occur, for example, in an emergency situation in which one ... -
Auditory Mismatch Negativity in Schizophrenia: Topographic Evaluation With a High-Density Recording Montage
(American Psychiatric Publishing, 1998)Objective: The mismatch negativity, a negative component in the auditory event-related potential, is thought to index automatic processes involved in sensory or echoic memory. The authors’ goal in this study was to examine ... -
Auditory processing abnormalities in schizotypal personality disorder: An fMRI experiment using tones of deviant pitch and duration
(Elsevier BV, 2008)Background: One of the cardinal features of schizotypal personality disorder (SPD) is language abnormalities. The focus of this study was to determine whether or not there are also processing abnormalities of pure tones ... -
Auditory verbal hallucinations and the interhemispheric auditory pathway in chronic schizophrenia
(Informa UK Limited, 2014)Objectives—The interhemispheric auditory pathway has been shown to play a crucial role in the processing of acoustic stimuli, and alterations of structural and functional connectivity between bilateral auditory areas are ... -
Auditory-Cortex Short-Term Plasticity Induced by Selective Attention
(Hindawi Publishing Corporation, 2014)The ability to concentrate on relevant sounds in the acoustic environment is crucial for everyday function and communication. Converging lines of evidence suggests that transient functional changes in auditory-cortex ... -
Auditory-Motor Mapping Training: Comparing the Effects of a Novel Speech Treatment to a Control Treatment for Minimally Verbal Children with Autism
(Public Library of Science, 2016)This study compared Auditory-Motor Mapping Training (AMMT), an intonation-based treatment for facilitating spoken language in minimally verbal children with autism spectrum disorder (ASD), to a matched control treatment, ... -

Augmented expression of MYC and/or MYCN protein defines highly aggressive MYC-driven neuroblastoma: a Children's Oncology Group study
(Nature Publishing Group, 2015)Background: MYCN amplification with subsequent MYCN protein overexpression is a powerful indicator of poor prognosis of neuroblastoma patients. Little is known regarding the prognostic significance of the homologous MYC ... -
Augmented Inhibition from Cannabinoid-Sensitive Interneurons Diminishes CA1 Output after Traumatic Brain Injury
(Frontiers Media S.A., 2014)The neurological impairments associated with traumatic brain injury include learning and memory deficits and increased risk of seizures. The hippocampus is critically involved in both of these phenomena and highly susceptible ... -
An Augmented Lagrangian Based Compressed Sensing Reconstruction for Non-Cartesian Magnetic Resonance Imaging without Gridding and Regridding at Every Iteration
(Public Library of Science, 2014)Background: Non-Cartesian trajectories are used in a variety of fast imaging applications, due to the incoherent image domain artifacts they create when undersampled. While the gridding technique is commonly utilized for ... -
