Nested-PCR and TaqMan real-time quantitative PCR assays for human adenoviruses in environmental waters.

Human adenovirus (HAdV) infections can occur throughout the year. Cases of HAdV-associated respiratory disease have been more common in the late winter, spring, and early summer. In this study, to provide viral pollution data for further epidemiological studies and governmental actions, the presence of HAdV in the aquatic environment was quantitatively surveyed in the summer.

A simple, innovative way to reduce rhinitis symptoms after sedation during endoscopy.

Background: Supplmental oxygen is routinely given via nasal cannula (NC) to patients undergoing moderate sedation for endoscopy. Some patients complain of profuse rhinorrhea and⁄or sneezing after the procedure, which results in additional medical costs and patient dissatisfaction.

Objectives: To determine the causal relationship between the route of oxygen delivery and troublesome nasal symptoms, and to seek possible solutions.

Induction of hepatic glutathione S-transferase and UDP-glucuronosyltransferase activities by ketamine in rats.

Background: Ketamine has been shown to induce rat cytochrome P-450 in a way similar to phenobarbital. However, whether ketamine is able to induce glutathione S-transferase (GST) and UDP-glucuronosyltransferase (UGT), two major phase II drug-metabolizing enzymes, remains unclear. The present study aimed to investigate the effect of ketamine on GST and UGT activities in rats.
