BACKGROUND This pilot study examined airway characteristics during upper endoscopy to determine who is at high risk for obstructive sleep apnea. METHODS Patients undergoing routine upper endoscopy were divided into 2 groups according to the Berlin Questionnaire (high and low risk for sleep disordered breathing). Patients underwent routine upper endoscopy using propofol sedation. The airway wa...

The mechanism by which atherosclerotic plaque causes stroke and transient ischemic attack is not fully understood. One possibility is that the plaque stenosis may set up hemodynamic conditions causing local arterial wall collapse. Arterial wall collapse may, in turn, affect the integrity of the plaque. This study was designed to define the effects of stenosis on the production of arterial wall ...

Each period of Western history has given rise to puzzles that have stumped most observers. From the collapse of the Carolingian empire to the fall of the Berlin Wall, for every suggested explanation, there is a convincing counter-argument. Rather than search for a custom-tailored explanation of each event, this study presents evidence of an overall pattern generated by mutations in information ...

In this study, the progressive collapse potential of seismically designed steel plate shear wall (SPSW) systems is investigated using the alternate path method, and their performances are compared with those of the conventional special moment frame (SMF) systems. Nonlinear static and dynamic analyses are conducted to follow the progressive collapse of the structures, and their ability of absorb...
