The Tagmatized Echinoderm, Richard L. Turner

Ocean Engineering and Marine Sciences Faculty Publications

Synopsis Tagmosis is a derived condition of metamerism in annelids, arthropods, and chordates in which groups of adjacent segments are modified to perform specific functions. Examples are the clitellum of earthworms, the carapace of lobsters, and the sacrum of tetrapods, to mention a few. The argument is advanced here that examples of tagmosis are not hard to find among echinoderms, a fourth major group of metameric animals; but the degree of tagmosis is weak in most cases. The first few segments of the axial skeleton are often conjoined as a perioral tagma (e.g., the jaws and other parts of the …

Sophisticated Song: Exploring The Evolution And Ontogeny Of Large Repertoires And Syntax Usage In The Bachman’S Sparrow (Peucaea Aestivalis), Heather Jean Wolverton

Electronic Theses and Dissertations

While humans have the most complex vocal communication system, many of the features that make human language so intricate can be found in other taxa. One building block of language commonly studied in animal communication is syntax, or the organization of vocalizations. Birds, wolves, and cetaceans all display complex vocal signaling that utilizes syntax. Understanding how syntax functions in different taxa can help illuminate the evolution and development of human language and the role it plays in social cognition. The Bachman’s sparrow (Peucaea aestivalis) is a species of songbird that utilizes syntax in the form of preferred transitions …

Neuroactive Metabolite Assessment Of Gaba-Producing Probiotics For Healthy Aging, Sanaly Nava, Dishant Aggarwal, Samjhana Pradhan, Ken Aho, Cynthia Blanton, Javier Ochoa-Repáraz, Kavita Sharma

Idaho Conference on Undergraduate Research

Aging is a gradual process of weakening bodily function that leads to decline in physical, cognitive and behavioral abilities. Gamma-amino butyric acid (GABA), a major neurotransmitter in the central nervous system, is produced by both neurons and gut bacteria, and plays a crucial role in numerous physiological functions. Notably, aging is associated with a decline in GABA production and alterations in gut microbiota. Therefore, restoring GABA production by correcting dysbiosis presents a potential strategy for managing age-related functional decline. To better understand how to support healthy aging, our study investigates the gut-brain axis and the potential of genetically modified GABA-producing …

Design And Development Of A Novel Lxrβ/Pparδ Dual Agonist For Memory Impairment And Pathology In 3xtg-Ad Animal Model Of Alzheimer's Disease, Meenakshi Singh, Ian Steinke, Vishnu Suppiramaniam

Faculty Articles

The rising prevalence of Alzheimer’s disease (AD) underscores an urgent need for neuroprotective strategies that modulate cholesterol metabolism, neuroinflammation, improve pathology, and cognitive function. While Liver X receptors (LXRs) and peroxisome proliferator-activated receptors (PPARs) are validated targets for enhancing amyloid-β and tau clearance, clinical translation of first-generation LXR agonists has been hindered by LXRα-mediated hepatic steatosis and hypertriglyceridemia. Here, we report the structure-based design of AU403, a potent, isoform-selective LXRβ/PPARδ dual agonist designed to bypass LXRα-driven hepatotoxicity. Molecular modeling indicates that AU403 achieves LXRβ selectivity by engaging residues Phe329 and Leu330 while avoiding the corresponding LXRα residues Arg305 and Leu316. …
