Removal of NO with the hexamminecobalt solution catalyzed by the carbon treated with oxalic acid.

NO can be removed at the same time with SO by aqueous Co(NH) solution. The reduction of Co(NH) to Co(NH) is catalyzed by activated carbon to regain the NO absorption ability of the scrubbing solution. Oxalic acid solution is explored to change the carbon surface to ameliorate its catalytic capability.

[Clinical and medication characteristics of senior hospitalized patients with chronic constipation].

Objective: To analyze the clinical features, risk factors and drug uses of senior hospitalized patients with chronic constipation.

Methods: A total of 162 hospitalized patients aged 85 years and over at our hospital during the period of January-March 2012 conducted a questionnaire survey. There were 137 males and 25 females.

Role of RhoA in platelet-derived growth factor-BB-induced migration of rat hepatic stellate cells.

Background: Although the migration of hepatic stellate cells (HSCs) is essential for hepatic fibrotic response, the detailed mechanisms involved are poorly understood. The aim of this study was to examine the role of Rho GTPases (especially RhoA) in platelet-derived growth factor (PDGF)-BB-induced migration of HSCs.

Methods: The migration of primary rat HSCs was evaluated using transwell Boyden chamber, while cytoskeletal changes were visualized by immunofluorescence staining of intracellular actins and vinculin.
