To investigate parasympathetic influences on the forehead microvasculature, blood flow was monitored bilaterally in seven participants with a unilateral facial nerve lesion during conjunctival irritation with Schirmer's strips and while breathing at 0.15 Hz. Blood flow and slow-wave frequency increased on the intact side of the forehead during Schirmer's test but did not change on the denervate...

PURPOSE To compare an ultrafast CT method for estimating regional cerebral blood flow with a more commonly used xenon-enhanced CT method. METHODS Xenon CT and ultrafast CT were used to estimate regional cerebral blood flow (rCBF) in 12 healthy beagle dogs. Measurements were obtained for left and right hemisphere, cortical gray matter, basal ganglia, and deep white matter. The ability of each ...

This paper explores the problem of tracking information flow in dynamic tree structures. Motivated by the problem of manipulating the Document Object Model (DOM) trees by browser-run client-side scripts, we address the dynamic nature of interactions via tree structures. We present a runtime enforcement mechanism that monitors this interaction and prevents a range of attacks, some of them missed...

OBJECTIVE To investigate whether patterns of dysphagia and swallowing laterality differ according to the location of brain lesions in patients with stroke. METHODS Patients with stroke >20 years of age were enrolled in this study. A videofluoroscopic swallowing study (VFSS) including the anterior-posterior view was used to assess swallowing. Patterns of swallowing were classified into three t...

Bottom intake is an intake structure which can be considered as an alternative for regular intakes in mountain streams Water in in taking from river are very vast and complicated issues, each project has special characteristics which should be considered. Water intake from riveris generally based on Pump and gravity method. The gravity method is more useful and common because of continuity and ...
