Background and objectives: Recurrent aphthous stomatitis (RAS) is a painful ulcerative lesion and its incidence is 20% in the society. Myrtus communis (myrtex) has been effective in the treatment of RAS. In this study, two different concentrations (2.5% versus 5%) of myrtex extract were evaluated to discover the most effective concentration for the treatment of RAS. Methods: In this randomized...

Methods to improve bearing capacity of footing resting of collapsing soil can, in fact, take two approaches, improving soil strength properties and intrusion of reinforcing sorces into soil. The footing is modeled by a square steel plate 0.1 by 0.1 m. The footing is loaded as to have a stress of 40 kPa and settlement is receded in dry and in soaking conditions. Two depths of the geo-mesh reinfo...

Enhanced VEGF secretion is found in human cancers and correlates with increased tumor neovascularization. ZD6474 is a p.o. bioavailable, VEGF flk-1/KDR receptor (VEGFR-2) tyrosine kinase inhibitor with antitumor activity in many human cancer xenografts and is currently ...
