Estimating received level in behavioral response studies through the use of ancillary data.

Marine mammals are known to respond to various human noises, including and in certain cases, strongly, to military active sonar. Responses include small and short-term changes in diving behavior, horizontal avoidance of an ensonified area, and mass strandings. Considerable research has been conducted using short-term biologging tags to understand these responses.

Female patients exhibit altered vasopressin-induced coronary microvascular contractile response and molecular signaling following cardiac surgery.

Background: Emerging data suggest women have worse outcomes than men following cardioplegia and cardiopulmonary bypass (CP/CPB). Altered coronary microvascular function affecting myocardial perfusion may contribute, but human translational studies are lacking.

Methods: Viable coronary microvessels (<200 μ m) were dissected from human atrial samples collected before and after CP/CPB from a subset of 108 patients enrolled.

Historical baleen plates indicate that once abundant Antarctic blue and fin whales demonstrated distinct migratory and foraging strategies.

Southern hemisphere blue () and fin () whales are the largest predators in the Southern Ocean, with similarities in morphology and distribution. Yet, understanding of their life history and foraging is limited due to current low abundances and limited ecological data. To address these gaps, historic Antarctic blue ( = 5) and fin ( = 5) whale baleen plates, collected in 1947-1948 and recently rediscovered in the Smithsonian National Museum of Natural History, were analyzed for bulk (δC and δN) stable isotopes.

Was It Worth It? Critical Evaluation of a Novel Outcomes Measure in Oncologic Palliative Surgery.

Background: Patient selection for palliative surgery is complex, and appropriate outcomes measures are incompletely defined. We explored the usefulness of a specific outcomes measure "was it worth it" in patients after palliative-intent operations for advanced malignancy.

Study Design: A retrospective review of a comprehensive longitudinal palliative surgery database was performed at an academic tertiary care center.
