Oropharyngeal and nasopharyngeal airways: I (1880-1995).
PURPOSE During the past decade the laryngeal mask airway (LMA) has dominated literature about airways for use during general anaesthesia. The LMA addresses clearly defined clinical objectives. The purpose of this study is to determine whether those objectives were described collectively with reference to earlier airway designs. METHODS The anaesthesia sections of Index Medicus 1880-1995 were ...
متن کاملOn the origin of the unusual orbit of Comet 2P/Encke
The orbit of Comet 2P/Encke is difficult to understand because it is decoupled from Jupiter—its aphelion distance is only 4.1 AU. We present a series of orbital integrations designed to determine whether the orbit of Comet 2P/Encke can simply be the result of gravitational interactions between Jupiter-family comets and the terrestrial planets. To accomplish this, we integrated the orbits of a l...

Historically, since the metabolism of administered peptide/protein drugs (“biotherapeutics”) has been expected to undergo predictable pathways similar to endogenous proteins, comprehensive biotherapeutic metabolism studies have not been widely reported in the literature. However, since biotherapeutics have rapidly evolved into an impressive array of eclectic modalities, there has been a shift t...
متن کاملThe orbital elements of a meteoroid after its ejection from a comet
This article examines the changes in the orbital elements of particles ejected from the nucleus of an active comet. We extend the work of Plavec (1957) to include changes in all the orbital elements resulting from the ejection process.We take into account the constraints that must be met before a meteoroid particle can be observed as a meteor. In addition we constrain particle ejection to take ...
