Sedative And Neurotoxic Properties Of Brexanolone Compared To Midazolam In The Developing Rodent Brain, Jacob Huffman
Sedative And Neurotoxic Properties Of Brexanolone Compared To Midazolam In The Developing Rodent Brain, Jacob Huffman
Dissertations
The developing brain is susceptible to extensive neurotoxicity following exposure to sedative/anesthetic drugs (SADs). Every year hundreds of thousands of children around the world are exposed to SADs with no viable non-neurotoxic agents approved for clinical use. Allopregnanolone (AlloP) has well-established sedative effects in adults and neonates. AlloP and many SADs produce sedation/anesthesia through allosteric modulation of GABAA receptors, which is one of two principal mechanisms behind SAD-induced neurotoxicity. Evidence suggests AlloP has the unique capacity to regulate key apoptotic factors in adults and is widely involved with critical stages of neurodevelopment, indicating this neurosteroid might serve as a …
Signature Whistle Production During A Bottlenose Dolphin Group Integration, Megan S. Broadway
Signature Whistle Production During A Bottlenose Dolphin Group Integration, Megan S. Broadway
Dissertations
Bottlenose dolphins are an important species of interest because they possess a variety of abilities that are relatively rare in the animal kingdom, one being complex acoustic communication. Signature whistles - distinctive calls that are unique for each individual – are one of the most studied call types, but we know little about how these calls are used in various contexts, such as during an introduction. Looking at the socio-behavioral context in which signature whistles are used is likely the best way of learning how these whistles are used in a particular context (Caldwell, Caldwell, & Tyack, 1990). For this …
Effects Of Trophic Relationships On Oyster Reef Restoration Success In The Mississippi Sound, Virginia Robin Fleer
Effects Of Trophic Relationships On Oyster Reef Restoration Success In The Mississippi Sound, Virginia Robin Fleer
Dissertations
Natural and anthropogenic changes resulting from altered hydrology, hurricanes, variable precipitation, and the BP oil spill have all taken their toll on oyster reefs in Mississippi. In response, oyster reef restoration efforts are currently underway within the Northern Gulf of Mexico. In order to understand why these efforts succeed or fail, it is crucial to consider predator-prey relationships within the context of the trophic dynamics of oyster reefs. Thus, for this dissertation study I integrated a multidisciplinary approach to understanding key trophic interactions affecting oyster recruitment, growth and survival, comprising field sampling, manipulative lab experiments, and individual-based modeling. Spat settlement …
