Abstract Background Up to 40% of patients with severe aortic stenosis (SAS; indexed valve area (AVAi) <0.6 cm2/m2) present low transvalvular mean gradient (MG) despite a normal left ventricular ejection fraction (EF). There is intense debate about the prognostic significance such entity, some referring it as an advanced form disease, others intermediate between moderate and form. Objecti...

This paper presents how a successful SAS/AF application used by scientists and researchers was presented to users through a Windows application for usability and speed whilst retaining the robustness of the SAS 9. SAS Integration Technologies was used to interface the tried and trusted algorithms to a bespoke application developed using Microsoft Visual Basic .NET. This created an interoperable...

PURPOSE The purpose of the study was to: (1) evaluate the subarachnoid space (SAS) width and pial artery pulsation in both hemispheres, and (2) directly compare magnetic resonance imaging (MRI) to near-infrared transillumination/backscattering sounding (NIR-T/BSS) measurements of SAS width changes in healthy volunteers. METHODS The study was performed on three separate groups of volunteers, c...

Plants respond to a reduction in the red/far-red ratio (R:FR) of light, caused by the proximity of other plants, by initiating morphological changes that improve light capture. In Arabidopsis, this response (shade avoidance syndrome, SAS) is controlled by phytochromes (particularly phyB), and is dependent on the TAA1 pathway of auxin biosynthesis. However, when grown in real canopies, we found ...

Background. The aim of this study is to present a method of lid laxity evaluation and investigate whether there is an association between floppy eyelid syndrome (FES) and body mass index (BMI) in sleep apnea syndrome (SAS) patients compared to normal subjects. Method. A total of 135 participants (81 patients with SAS and 54 normal subjects) had a full ophthalmologic examination. The presence of...

Background The surgical Apgar score (SAS) is a 10-point scale using the lowest heart rate, lowest mean arterial pressure, and estimated blood loss (EBL) during surgery to predict postoperative outcomes. The SAS has not yet been validated in liver transplantation patients, because typical blood loss usually exceeds the highest EBL category. Our primary aim was to develop a modified SAS for liver...

Introduction: Autonomic heart rate (HR) control evaluated by means of HR variability measures has been widely accepted as important information of cardiovascular function being a marker of sudden death. Methods: Polysomnography was performed in 405 CAD pts (mean age 60.7 yr.) pts, including 200 pts with CHF (mean age 63.4 yr.). Sleep apnea syndrome (SAS) was observed in 46 pts (mean age 64.2 yr...
