Vascular Reactivity by Blood Oxygen Level Dependent Functional MRI in Cerebral Amyloid Angiopathy: Comparison with Alzheimer's Disease and Assessment of Longitudinal Change
Cerebral amyloid angiopathy (CAA) refers to the deposition of Abeta (Aβ) peptides in the brains small blood vessels leading to hemorrhagic stroke and cognitive impairment. Aβ is toxic to smooth muscle cells and impairs blood flow regulation. Reduced blood oxygen level dependent (BOLD) signal …

Multi-modality imaging assessment of cerebral small vessel disease biomarkers after stroke due to spontaneous intracerebral haemorrhage
… diseases (SVDs). Cerebral amyloid angiopathy (CAA) and arteriolosclerosis (non-CAA SVD) are the two main types of SVD associated with ICH. The risk of recurrent ICH and post-stroke dementia may be higher with CAA-associated ICH compared with non-CAA SVD-associated ICH. It is, therefore, …

Towards a grounded theory of computer-assisted assessment uptake in UK universities
… to appear. <br/> Computer-assisted assessment (CAA) is seen by many as one way of meeting these conflicting demands. CAA has considerable potential both to ease the assessment load and to provide innovative and powerful modes of assessment. Moreover, as the use of ICT increases there may be …

The effect of aberrations and light scatter on visual performance at photopic and mesopic light levels
The Contrast Acuity Assessment (CAA) test was developed to assess the minimum spatial vision requirements for commercial pilots. The goal of the CAA test was for it to be sensitive to retinal image degradation in subjects who had undergone excimer laser refractive surgery. Increased aberrations and …

Cerebral Amyloid Angiopathy and Transition Metals in Alzheimer's Disease
… iron overload. Cerebral amyloid angiopathy (CAA) is a vascular manifestation of Alzheimer's disease present to some degree in up to 95% of Alzheimer's disease patients. This vasculopathy results in vascular inflammation and fragility which produces clinically detectable bleeding (by …

The flow and variability of sea-ice in the Canadian Arctic Archipelago: modelling the past (1950-2004) and the future (2041-2060)
… retreat in the Canadian Arctic Archipelago (CAA) is expected. As most global climate models do not resolve the CAA region, a fine-resolution regional model is developed to provide a sense of possible changes in the CAA sea-ice. This ice-ocean coupled model is forced with atmospheric data for …

Monochloracetat in der Umwelt
… ist der mutagene Chloracetaldehyd (CAA). Das Schicksal des CAA wurde mit UV-Spektroskopie und in verschiedenen Smogkammer-Experimenten untersucht. Aufgrund der gewonnenen Ergebnisse ist zu schlussfolgern, dass CAA zu rund 40 % durch Photolyse und zu 60 % durch Reaktion mit …

Cerebral Amyloid Angiopathy-Causing Beta-Amyloid Variants Have Altered Effects on the Clotting System
<p>Cerebral amyloid angiopathy (CAA), where beta-amyloid (Aβ) deposits around cerebral blood vessels, is a major contributor of vascular dysfunction in Alzheimer's disease (AD) patients. However, the molecular mechanism underlying CAA formation and CAA-induced cerebrovascular pathologies, including …

Computer-assisted auscultation as a screening tool for cardiovascular disease : a cross-sectional study
… and experience. Computer- assisted auscultation (CAA) is an objective referral-decision support tool that aims to minimise inappropriate referrals. This study evaluated the sensitivity and specificity of 2 CAA systems, Cardioscan® and Sensi®, in detecting echo-confirmed cardiac abnormalities in 79 …

The Role of Perivascular Fibrosis In Post-Stroke Glymphatic Impairment and Cerebral Amyloid Angiopathy
… of Aβ, termed cerebral amyloid angiopathy (CAA). I hypothesize that an abnormal pattern of extracellular matrix deposition within the vascular basement membrane, termed fibrosis, impairs Aβ drainage from the aged brain after stroke. I further hypothesize that inhibition of astrocytic …

Clinical outcome and Predictive factors of Coronary aneurysm after Percutaneous Coronary Intervention
Coronary artery aneurysms (CAAs) defined as angiographic luminal dilatation (50% larger than the adjacent reference vessel) at the site of stent implantation are rare and the reported incidence varies from 0.3% to 6%(Aoki et al., 2008). A new term, peri-stent contrast staining (PSS) was defined as …
