BACKGROUND Myocardial fibers are grouped into lamina (or sheets) 3 to 4 cells thick. Fiber shortening produces systolic left ventricular (LV) wall thickening primarily by laminar extension, thickening, and shear, but the regional variability and transmural distribution of these 3 mechanisms are incompletely understood. METHODS AND RESULTS Nine sheep had transmural radiopaque markers inserted ...

BACKGROUND The epithelial reticular basement membrane (Rbm) of the airway wall thickens in patients with asthma. However, whether the thickening parallels whole airway wall thickening, which limits airflow, is unknown. The aim of this study was to examine the correlation between the bronchial Rbm thickening and whole airway wall thickening in asthma. In addition, the association of Rbm and whol...

The effect of the addition of potato or maize on the shear-thickening behavior of semidilute solutions of maize was examined. The experiments were conducted at 25°C using 90/10 weight–weight dimethyl sulfoxide (DMSO)–water as the solvent. The addition of amylose to maize amylopectin reduced and eventually eliminated the observed shear-thickening behavior of maize amylopectin. When potato amylos...

AIM Pituitary apoplexy is an infrequent but potentially devastating complication in patients with pituitary adenomas. Previous studies have cited an association between MR visualized sphenoid sinus mucosal thickening and apoplexy. However, uncertainties still remain on the significance and temporal association of this finding with pituitary apoplexy. We provide a clinical study that better deli...
