BACKGROUND AND PURPOSE There are limited data on the prevalence and prognosis of asymptomatic intracranial stenosis (AIS). METHODS Baseline cerebral angiograms and MR angiograms were used to determine AIS (50% to 99%) coexistent to symptomatic intracranial stenosis for patients enrolled in the Warfarin-Aspirin Symptomatic Intracranial Disease study. RESULTS Coexisting AIS were detected in 1...

Structural plasticity of the axon initial segment (AIS), the trigger zone of neurons, is a powerful means for regulating neuronal activity. Here, we show that AIS plasticity is not limited to structural changes; it also occurs as changes in ion-channel expression, which substantially augments the efficacy of regulation. In the avian cochlear nucleus, depriving afferent inputs by removing cochle...

What does the marine Automatic Identification System (AIS) vessel tracking mean for mariners at sea and operations staff on shore during emergency response operations? Real-time AIS and e-Navigation related technologies enable closer coordination between all involved parties. Recorded historical AIS data give insight into what occurred before, during, and after an incident. Historical AIS analy...

Adolescent Idiopathic Scoliosis (AIS) is characterized by three-dimensional deformation of the spine resulting in alterations of body posture and segment alignment [1]. Changes in body posture have been found to relate to stability deficits in AIS patients, which may be exacerbated by AIS severity [2]. Previous work has related AIS patients have reduced postural stability characterized by requi...

PURPOSE Adolescent idiopathic scoliosis (AIS) is often associated with low bone mineral content and density (BMC, BMD). Bracing, used to manage spine curvature, may interfere with the growth-related BMC accrual, resulting in reduced bone strength into adulthood. The purpose of this study was to assess the effects of brace treatment on BMC in adult women, diagnosed with AIS and braced in early a...

Although it is generally recognized that certain α-subunits of γ-aminobutyric acid type A receptors (GABAARs) form enriched clusters on the axonal initial segment (AIS), the degree to which these clusters vary in different brain areas is not well known. In the current study, we quantified the density, size, and enrichment ratio of fluorescently labeled α1-, α2-, or α3-subunits aggregates co-loc...

OBJECTIVE To compare HIV seroprevalence estimates obtained from antenatal care (ANC) sentinel surveillance surveys in Ethiopia, Kenya, Malawi, Tanzania and Uganda with those from population-based demographic and health surveys (DHS) and AIDS indicator surveys (AIS). METHODS Geographical information system methods were used to map ANC surveillance sites and DHS/AIS survey clusters within a 15-...

Androgen insensitivity syndrome (AIS) is the most common specific cause of 46,XY disorder in sex development. The androgen signaling pathway is complex but so far, the only gene linked with AIS is the androgen receptor (AR). Mutations in the AR are found in most subjects with complete AIS but in partial AIS, the rate has varied 28–73%, depending on the case selection. More than over 800 entries...

BACKGROUND We aimed to compare the morphological features of pure ground-glass nodules (GGNs; diameter, ≤10 mm) on thin-section computed tomography (TSCT) with their histopathological results in order to identify TSCT features differentiating between atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA). METHODS Between January and De...

BACKGROUND AND PURPOSE Traumatic brain injury (TBI) leads to nearly 300 000 annual US hospitalizations and increased lifetime risk of acute ischemic stroke (AIS). Occurrence of AIS immediately after TBI has not been well characterized. We evaluated AIS acutely after TBI and its impact on outcome. METHODS A prospective database of moderate to severe TBI survivors, admitted to inpatient rehabil...
