A novel methodology for localized exposure of chorioallantoic membrane vessels to toxins affecting angiogenesis
Meeting Abstract P1.59 Jan. 4 A novel methodology for localized exposure of chorioallantoic membrane vessels to toxins affecting angiogenesis. KUMORDZIE, A*; BURRGREN, W; Univ. of North Texas; Univ. of North Texas aek0049@unt.edu The chorioallantoic membrane (CAM) of the avian egg is a model vascular bed for understanding how toxins affect angiogenesis. Localized delivery of toxins is crucial […]

Flatfish metamorphosis is accompanied by a 90 degree change in […]
The Endocrine System just before the Backbone Genomics of the Spineless
Meeting Abstract BERN.1 Jan. 5 The Endocrine System just before the Backbone: Genomics of the Spineless SHERWOOD, NM; Univ. of Victoria, BC Canada nsherwoo@uvic.ca The nature of the endocrine system in animals that evolved just before the vertebrates has been difficult to study. Now, the release of the complete genome for two groups lacking a backbone, amphioxus […]
The Aerodynamic and Neurophysiological Mechanisms of Animal Flight through the Lens of Evolution
Meeting Abstract BART.1 Jan. 4 The Aerodynamic and Neurophysiological Mechanisms of Animal Flight through the Lens of Evolution Altshuler, D.; University of California, Riverside One of the most remarkable adaptations in animals is the ability to fly. Birds, bats and insects are among the most successful of terrestrial organisms, and their colonization of diverse habitats and ecological […]
