Jelly snakes to reduce early postoperative vomiting in children after adenotonsillectomy: The randomized controlled snakes trial.

Background: Despite the use of dual antiemetic agents, postoperative nausea and vomiting (PONV) occurs in an unacceptably large number of patients post-tonsillectomy. There has been increased interest in alternative and non-pharmacological treatments for PONV e.g.

Flight system morphology and minimum flight temperature in North American cicadas (Insecta: Hemiptera: Cicadidae).

Thermal responses in cicadas have been studied for many years. The minimum flight temperature (MFT) does not show the same relationship to habitat and behavior as other thermal responses. We measured live mass, wing length, wingspan, wing area and wing loading in an attempt to correlate these morphological parameters to the MFT.
