OBJECTIVES/HYPOTHESIS To determine the resorption rate and biocompatibility characteristics of novel cross-linked hydrogel ventilation tubes and varied formulations of polyester ventilation tubes in a Chinchilla model. STUDY DESIGN Animal Study. METHODS Three cross-linked glycosaminoglycan hydrogel ventilation tubes fabricated by cross-linking thiol-modified chondroitin sulfate or thiol-mod...
Bioassayswere conducted to examine the response ofCoptotermes formosanus Shiraki andReticulitermesflavipes(Kollar) towholebodyextractsof termites.Bioassayswerealsoconducted to determine if trail-following behavior could be elicited in glass tubes after different lengths of exposure to termites and if termites showed any species-speciÞc response to exposed tubes. Trailfollowing behaviorwas elici...
Experiments on the entrainment of surface sediments around polychaete tubes at natural and manipulated densities were conducted in a recirculating seawater flume. Intact cores with either 0 or 8 Diopatra cuprea tubes per 0.01 m* plus associated assemblages were collected in the field. Sediments which contained D. cuprea tubes had natural macrofaunal densities > 5 x those of sediments without tu...
