A catenin-dependent balance between N-cadherin and E-cadherin controls neuroectodermal cell fate choices.

Characterizing endogenous protein expression, interaction and function, this study identifies in vivo interactions and competitive balance between N-cadherin and E-cadherin in developing avian (Gallus gallus) neural and neural crest cells. Numerous cadherin proteins, including neural cadherin (Ncad) and epithelial cadherin (Ecad), are expressed in the developing neural plate as well as in neural crest cells as they delaminate from the newly closed neural tube. To clarify independent or coordinate function during development, we examined their expression in the cranial region.

Bifurcated endoprosthesis for treatment of aortoiliac occlusive lesions.

Purpose: To report our initial experience with a bifurcated endoprosthesis in the management of aortoiliac occlusive disease.

Methods: From May 2001 to February 2004, 112 patients were referred to our institution for the management of aortoiliac disease. Among these, 5 (6%) patients (3 men; mean age 57.
