BACKGROUND AND PURPOSE Subclinical atherosclerotic plaques are common in patients with pontine infarctions (PIs) but without basilar artery (BA) stenosis. We hypothesized that BA plaque locations may differ by PI type and vertical location as well as vertebrobasilar artery geometry. METHODS Ninety-six patients with PI but without BA stenosis on magnetic resonance imaging (MRI) and magnetic re...

This paper presents numerical modeling technique for Dhajji-Dewari structures (timber-braced rubble stone masonry), and its application for the evaluation of in-plane force-deformation capacity of Dhajji wall panels of different configuration of bracings. Dhajji structures are mainly composed of vertical and horizontal timber posts and braced using diagonal bracings and horizontal studs. Wall o...

Objective- The purpose of this study was to assess and describe the radiographic anatomy of the bony structures in the head of sheep. Design- Experimental study. Animals- Fifteen mature Afshari sheep. Procedures- Radiographs were made out of the head of the animals in lateral and dorsoventral views. Radiographic anatomy was analyzed with results from gross dissection of 5 specimens. Results- De...

BACKGROUND Parametric-colored digital subtraction angiography using Tmax is almost a routine angiographic imaging procedure, currently. The current feasibility study is aimed to using the imaging to monitor treatment effects while embolizing indirect carotid-cavernous fistulas (CCF). METHODS Ten patients with CCFs receiving embolization and 40 patients with normal circulation time were recrui...

A new genus and species of Papaverellus aureocingulatus from Brazil, belonging to the asilid subfamily, is described and illustrated. Photographs of the habitus of the male and female in lateral view, and male terminalia in ventral view are provided. The systematic position of Papaverellus gen. nov. is suggested and will be addressed in a future paper.
