AIMS Agonists that evoke smooth muscle cell hyperpolarization have the potential to stimulate both local and conducted dilation. We investigated whether the endothelium-dependent vasodilators acetylcholine (ACh) and SLIGRL stimulated conducted dilation and whether this was altered by deficiency in apolipoprotein E (ApoE(-/-)). METHODS AND RESULTS Isolated mesenteric arteries were cannulated, ...

Background. Atherosclerosis has been associated with loss of artery wall distensibility in human cadavers and in experimental animal models, giving it the lay term "hardening of the arteries." Methods and Results. To assess the effect of calcification on arterial distensibility, balloon pressure and volume were recorded during dilation of calcified aortas in Watanabe heritable hyperlipidemic (W...

introduction: the main purpose of this study was to compare transient ischemic dilation (tid) ratios in spect-low dose ct and spect myocardial perfusion imaging (mpi) by application of different quantitative programs and quantify the possible shift in the upper normal limits of tid ratio in the spect-ct mpi. methods: 149 patients with low pre-test probability for coronary artery disease (cad),...

We investigate dilation-induced surface deformations in a Discontinuous Shear Thickening (DST) suspension to determine the relationship between dilation and stresses DST. Video is taken at two observation points on of rheometer while shear normal are measured. A roughened observed as particles poke through liquid-air interface, corresponding dilation. Dilation events found be intermittent local...

transient ischemic left ventricular dilation (tid) is a marker of severe and extensive coronary artery disease as well as an increased risk of adverse outcomes. the patients with more severe and extensive ischemia, multivessel-type of perfusion abnormality as well as patients with left anterior descending artery (lad) territory perfusion abnormality have more probability of having tid. evaluati...

introduction: despite wide use of hyoscine by midwives and doctors as an adjunct to labor, the obstetrics literature contains few references to the effect of this drug. this study was a double blinded, randomized controlled trial of primigravidas in iran to determine the effects of hyoscine intravenous injection on parturition (labor). methods:one hundred primigravidas in uncomplicated spontane...

results in group 1, the mean largest and cumulative stone diameters, respectively, were 18.7 ± 5.7 mm and 45.0 ± 12.0 mm. in group 2, the mean volume was 6,288.4 ± 2,733.0 mm3. the overall sf was 96.4% (100% for group 1 and 75% for group 2). the mean number of sessions of eswl and urs, respectively, was 1.4 ± 0.7 and 0.8 ± 0.9 in group 1 and 4.0 ± 2.0 and 1.5 ± 1.3 in group 2. the mean times to...

Dilation occurs when upper and lower probability estimates of some event E are properly included in the upper and lower probability estimates of the probability of E conditional on another event F , resulting in a change from a more precise estimate of E to a less precise estimate of E upon learning F . Strict dilation occurs when E is dilated by every event in a partition, which means that som...

a common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. gastric injury has been observed in patients who ingested alkali. gastric outlet obstruction (goo) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion....

Given a planar graph G, the graph theoretic dilation of G is defined as the maximum ratio of the shortest-path distance and the Euclidean distance between any two vertices of G. Given a planar point set S, the graph theoretic dilation of S is the minimum graph theoretic dilation that any triangulation of S can achieve. We study the graph theoretic dilation of the regular n-gon. In particular, w...
