Does amlodipine treatment prevent angiotensin II-induced human umbilical vein endothelial cell apoptosis?
Our data demonstrate that amlodipine ameliorates Ang II-induced endothelial apoptosis, which is likely associated with the elevation of Bcl-2/Bax ratio and reduction of the LOX-1 expression.
Chromoendoscopy allows easy detection of mucosal lesions in the colon and facilitates visualization of the margins of flat lesions. This technique unmasks multiple mucosal lesions which are not identified by routine video colonoscopy. The pit pattern seen after staining allows differentiation between hyperplastic and adenomatous lesions which may have consequences with regard to the endoscopic interventions needed.
