BACKGROUND Xylometazoline is a nasal decongestant spray that constricts nasal blood vessels and increases nasal airflow, enabling patients with a blocked nose to breathe more easily. The purpose of this study was to characterize objectively and subjectively the decongestant and additional effects of xylometazoline in the common cold. METHODS A double-blind, placebo-controlled, parallel group ...

Since its initial specification, CORBA hás become a de Jacto standard for the development of object-oriented distributed applications. In spite of some important features such as support for interoperability and heterogeneity, the CORBA specification, until very recently, neither addressed object replication nor reliable communication between objects, which are key components to provide fault t...

One of the most attractive aspects of the Common Object Request Broker Architecture (CORBA) lies in its open standard nature. Code that is based only on constructs described in the CORBA speciication is portable between Object Request Brokers (ORBs), without depending on any single ORB implementation. However, this portability feature is not completely achieved in real-world applications. This ...

Animal models have shown that peripheral chemoreceptors alter their firing patterns in response to changes in plasma osmolality, which, in turn, may modulate sympathetic outflow. The purpose of this study was to test the hypothesis that increases in plasma osmolality augment muscle sympathetic nerve activity (MSNA) responses to chemoreceptor activation. MSNA was recorded from the peroneal nerve...
