Abstract Background: End-to-side esophagojejunostomy has almost always been associated with some degree of dysphagia. To overcome this complication we decided to perform an end-to-end anastomosis and compare it with end-to-side Roux-en-Y esophagojejunostomy. Methods: In this prospective study, between 1998 and 2005, 71 patients with a diagnosis of gastric adenocarcinoma underwent total gastrec...

The coquina clam, Donax variabilis, rides flow from waves, migrating shoreward during rising tides and seaward during falling tides. This method of locomotion, swash-riding, is controlled not only behaviorally but also morphologically. The shape of this clam causes it to orient passively; a clam rotates in flow, usually in backwash, until its anterior end is upstream. Rotation is about a vertic...

Bats have been shown to use information from the Earth's magnetic field during orientation. However, the mechanism underlying this ability remains unknown. In this study we investigated whether bats possess a polarity- or inclination-based compass that could be used in orientation. We monitored the hanging position of adult Nyctalus plancyi in the laboratory in the presence of an induced magnet...
