Complex systems are made of large numbers of components, where each component may itself be composed of multiple subsystems. The size and complexity of such systems makes it impossible to design and study them using ad hoc methods. Thus, there is a growing need for powerful modeling environments to assist in the design and maintenance of complex systems.(More)
High tensions of carbon monoxide (CO), relative to oxygen, were used as a tool to investigate the mechanism of chemotransduction. In an in vitro whole organ, rat carotid body preparation, CO increased sinus nerve chemoafferent discharge in the dark, an effect that was significantly reduced (by ca 70 %) by bright white light and by the removal of(More)
1. Plasma adenosine concentration increases during hypoxia to a level that excites carotid body chemoreceptors by an undetermined mechanism. We have examined this further by determining the electrophysiological responses to exogenous adenosine of sinus nerve chemoafferents in vitro and of whole-cell currents in isolated type I cells. 2. Steady-state,(More)
BACKGROUND Carcinoma of the thyroid gland is an uncommon cancer, but the most frequent malignancy of the endocrine system. Most thyroid cancers are derived from the follicular cell. Follicular carcinoma (FTC) is considered more malignant than papillary thyroid carcinoma (PTC), and anaplastic thyroid cancer (ATC) is one of the most lethal human cancers.(More)
