OBJECTIVE The mechanisms responsible for maintaining the differentiated phenotype of adult vascular smooth muscle cells (VSMCs) are incompletely understood. Reactive oxygen species (ROS) have been implicated in VSMC differentiation, but the responsible sources are unknown. In this study, we investigated the role of Nox1 and Nox4-derived ROS in this process.(More)
BACKGROUND AND PURPOSE Limiting intracerebral hemorrhage (ICH) and intraventricular hemorrhage (IVH) expansion is a common target for acute ICH studies and, therefore, accurate measurement of hematoma volumes is required. We investigated the amount of hematoma volume difference between computed tomography scans that can be considered as measurement error.(More)

According to current concepts, it is not feasible to associate achlorhydria with normal gastric mucosa. We have found in a group of high altitude dwellers, that it is possible to associate achlorhydria with normal gastric mucosa verified by endoscopic and histological studies. In this case, basal achlorhydria is associated with resistance to histamine(More)
This study evaluates the response of the gastric mucosa to pentagastrin in a group (HAG) of 17 andean subjects compared to a similar group of 17 subjects at sea level (LAG). Both groups had normal fundic, body and antrum mucosa as demonstrated by endoscopic and histological means. Each group underwent two assays, the first one with a dose of 6 micrograms/kg(More)
Accurate characterization of cirrhotic nodules and early diagnosis of hepatocellular carcinoma (HCC) are of vital importance. Currently, computed tomography (CT) and magnetic resonance (MR) imaging are standard modalities for the investigation of new nodules found at surveillance ultrasonography (US). This article describes the successful integration of(More)
