Background: Formerly white matter abnormalities in a mixed group of migraine patients with and without aura were shown. Here, we aimed to explore white matter alterations in a homogeneous group of migraineurs with aura and to delineate possible relationships between white matter changes and clinical variables. Methods: Eighteen patients with aura, 25 migraine patients without aura and 28 contro...

Previous studies have provided evidence of structural and task-related functional changes in the brains of patients with migraine without aura. Resting-state brain activity in patients with migraine provides clues to the pathophysiology of the disease. However, few studies have focused on the resting-state abnormalities in patients with migraine without aura. In the current study, we employed a...

BACKGROUND Patients with partial epilepsy may report multiple types of aura during their seizures. The significance of the occurrence of multiple auras in the same patient is not known. METHODS The clinical and electrophysiologic characteristics of patients with more than one aura type (abdominal, auditory, autonomic, gustatory, olfactory, psychic, somatosensory, and visual auras), evaluated ...

In 1944, Leão described cortical spreading depression, the phenomenon now widely believed to underlie what some persons with headache perceive as “aura.” Aura is a somewhat misleading term because it can occur before a migraine, during or after a migraine, or occur without any associated headache. It can also occur with many other types of headache, but in clinical practice it is usually in ass...

AURA (Advanced Uncertain Reasoning Architecture) is a generic family of techniques and implementations intended for high-speed approximate search and match operations on large unstructured datasets [1]. AURA technology is fast, economical, and offers unique advantages for finding near-matches not available with other methods. AURA is based upon a high-performance binary neural network called a ...

BACKGROUND Migraine with aura (MA) has been identified as a risk factor for cardiovascular disease. Previous observation has also found higher prevalence of cardiovascular risk factors in migraineurs without aura (MO), but the results have been conflicting. The present study was conducted to assess the association between cardiovascular risk factors and migraine without aura among Iranians. M...

Background As a complex subjective experience, pain processing may be related to functional integration among intrinsic connectivity networks of migraine patients without aura. However, few study focused on the pattern alterations in the intrinsic connectivity networks of migraine patients without aura. Results Thirty-one migraine patients without aura and 31 age- and education-matched health...

Aura and Sindbis viruses are closely related alphaviruses. Unlike other alphaviruses, Aura virus efficiently encapsidates both genomic RNA (11.8 kb) and subgenomic RNA (4.2 kb) to form virus particles. Previous studies on negatively stained Aura virus particles predicted that there were two major size classes with potential T=3 and T=4 capsid structures. We have used cryoelectron microscopy and...
