Transplacental passage of vancomycin in the ex vivo human perfusion model.

OBJECTIVES: To determine maternal-fetal transplacental passage of vancomycin in the ex vivo human placental perfusion model. METHODS: Six term placentas were collected immediately after delivery and perfused with physiologic medium using the single cotyledon perfusion system. Vancomycin was added to the maternal medium and perfused through the maternal circulation of the cotyledon. Over a 1-h period in an open system, samples of the perfusate were collected at defined intervals from the fetal venous catheter and from the maternal effluence to assess vancomycin transfer. Thereafter, the system was closed for 1-5 h to establish accumulation. Transport fraction and clearance indexes were calculated by perfusing antipyrine 14C (positive control). Vancomycin was estimated by high pressure liquid chromatography and antipyrine 14C concentration was determined by liquid scintillation. RESULTS: Mean vancomycin maternal peak and trough concentrations ranged from 30.0 to 51.5 microg/ml and 7.7 to 16.4 microg/ml, respectively. Clearance indexes were minimal with a mean peak range of 0.000-0.080 and a mean trough range of 0.00-0.17. For each placenta, transport fraction for antipyrine 14C was > 1.85 with a single pass of > 40%. No accumulation of vancomycin was noted when the system was closed for 1-5 h. The mean peak clearance index was zero after perfusing the placenta for up to 5 h with 35.8 microg/ml of vancomycin. CONCLUSION: Transplacental passage of vancomycin was minimal in the ex vivo human placental perfusion model, with no detectable accumulation

Sea otter effects on trophic structure of seagrass communities in southeast Alaska

Previous research in southeast Alaska on the effects of sea otters Enhydra lutris in seagrass Zostera marina communities identified many but not all of the trophic relationships that were predicted by a sea otter-mediated trophic cascade. To further resolve these trophic connections, we compared biomass, carbon (δ13C) and nitrogen (δ15N) stable isotope (SI), and fatty acid (FA) data from 16 taxa at 3 sites with high and 3 sites with low sea otter density (8.2 and 0.1 sea otters km−2, respectively). We found lower crab and clam biomass in the high sea otter region but did not detect a difference in biomass of other seagrass community taxa or the overall community isotopic niche space between sea otter regions. Only staghorn sculpin differed in δ13C between regions, and Fucus, sugar kelp, butter clams, dock shrimp, and shiner perch differed in δ15N. FA analysis indicated multivariate dissimilarity in 11 of the 15 conspecifics between sea otter regions. FA analysis found essential FAs, which consumers must obtain from their diet, including 20:5ω3 (EPA) and 22:6ω3 (DHA), were common in discriminating conspecifics between sea otter regions, suggesting differences in consumer diets. Further FA analysis indicated that many consumers rely on diverse diets, regardless of sea otter region, potentially buffering these consumers from sea otter-mediated changes to diet availability. While sea otters are major consumers in this system, further studies are needed to understand the mechanisms responsible for the differences in biomarkers between regions with and without sea ottersWe thank Tiffany Stephens, Maggie Shields, Melanie Borup, Ashely Bolwerk, Nicole LaRoche, Tom Bell, Michael Stekoll and the rest of the Apex Predators, Ecosystems and Community Sustainability (APECS) team and 26 Earthwatch volunteers for assistance in the field and laboratory. Special thanks to Reyn Yoshioka, Natalie Thompson, the Coastal Trophic Ecology Lab, and Oregon Institute of Marine Biology for their assistance with fatty acid extractions, Melissa Rhodes-Reese at University of Alaska Southeast for water nutrient analysis, and Matthew Rogers and NOAA Auke Bay Laboratories for assistance with stable isotope analyses. This study was funded by the National Science Foundation (NSF #1635716, #1600230 to G.L.E.), through the generous support of Earthwatch, and a 56 NSF Graduate Research Fellowship, a North Pacific Re - search Board Graduate Student Research Award, an American Fisheries Society Steven Berkeley Marine Conservation Fellowship, and a Lerner Gray Memorial Fund (to W.W.R). This study was completed in partial fulfillment of the requirements for W.W.R.’s PhD at the University of Alaska Fairbanks and we thank committee members Dr. Franz Mueter and Dr. Anne Beaudreau for their comments on this project and the manuscript. Finally, we thank the 3 anonymous reviewers whose comments greatly improved the manuscript. This study was conducted on the traditional lands and waters of the Alaska Native Tlingit and Haida peoples. We are grateful for our access to these spaces and benefited from conversations and support from the members of Tribal communities and governments.Ye
