Background: The vascular function of Angiotensin II-type-2 receptors in adults is controversial. We sought their location and function in mouse aortic rings at young and old mice. Materials and Methods: Male C57Bl mice (aged 4 and 14 months) were killed by CO2. The descending thoracic aorta was cleaned and dissected into rings. Aortic rings were mounted in Krebs’ solution at 37 °C an...

Introduction: Idiopathic pulmonary fibrosis (IPF) is a relentlessly progressive and usually fatal lung disease of unknown etiology for which no effective treatments currently exist. In the adults type I and II pneumocytes, forms Components of the alveolar epithelial cells. In this study, we investigated the effect of thalidomide on the alveolar epithelial cells (type I and II pneumocytes) in ...

A combination of radiotracer and pore-water concentration measurements provide evidence for the occurrence of acetogenesis from CO2 in anoxic marine sediments that are ordinarily dominated by sulfate reduction and methanogenesis. In a month-long incubation experiment using sediments from Cape Lookout Bight, North Carolina, we measured H2 and acetate concentrations and monitored the incorporatio...
