Synthetic Complexes Of Relevance To Ni(Ii)-Containing Enzymes, Katarzyna Rudzka

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The work outlined herein presents an investigation of synthetic model complexes of relevance to the active sites of Ni(II)-containing enzymes, particularly urease, glyoxalase I, and acireductone dioxygenase. The research focuses on studying the structural and reactivity features of nickel complexes with biologically relevant substrates. The anion of acetohydroxamic acid is a well-known inhibitor of urease enzymes, including those isolated from Klebsiella aerogenes and Bacillus pasteurii. A precursor to the acetohydroxamate coordination in ureases is proposed to be an interaction between Ni(II) and acetohydroxamic acid. By using a novel supporting chelate ligand capable of secondary hydrogen bonding interactions a novel …

Garter Snake (Thamnophis) Natural History: Food Habits And Interspecific Aggression, Michael J. Edgehouse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Communication and recognition are closely intertwined and have been well documented in closely related species over the past several decades. These two types of behaviors often will aid in fostering or disrupting coexistence of similar species. Frequently, it is through different diet patterns that similar species will be able to coexist. This study uses data from 1972 through 2006 to demonstrate the diet of Thamnophis sirtalis, T. atratus, T. elegans, and T. couchii throughout their California range of sympatry with Taricha torosa. Additionally, an in depth examination of the diet of T. sirtalis, T. elegans, …

Movement Strategies Of Seed Predators As Determinants Of Plant Recruitment Patterns, Lorenzo Mari, Renato Casagrandi, Marino Gatto, Tal Avgar, Ran Nathan

Wildland Resources Faculty Publications

Plant recruitment in nature exhibits several distinctive patterns ranging from hump shaped to monotonically decreasing with distance from the seed source. We investigate the role of post-dispersal seed predation in shaping these patterns, introducing a new mechanistic model that explicitly accounts for the movement strategy used by seed eaters. The model consists of two partial differential equations describing the spatiotemporal dynamics of both seed and predator densities. The movement strategy is defined by how predators move in response to the different cues they can use to search for seeds. These cues may be seed density, seed intake, distance from the …

How Movement Properties Affect Prey Encounter Rates Of Ambush Versus Active Predators: A Comment On Scharf Et Al, Tal Avgar, Nir Horvitz, Luba Broitman, Ran Nathan

Wildland Resources Faculty Publications

Using an individual‐based model, Scharf and coworkers showed that ambush predators may encounter prey more frequently than active predators. We show that this surprising result emerges because active predators were oblivious to prey during movement, an assumption that refutes the common conception about active foraging and lessens the key difference between these foraging modes. A revised model confirms that active predators always encounter prey more frequently, unequivocally supporting the authors’ conclusion that the advantage of active predators diminishes as prey moves faster or more directionally. We suggest that movement‐dependent perception quality can determine the relative efficiency of these two foraging …

Distinct Contributions Of Model Masp1 And Masp2 Like Peptides To The Mechanical Properties Of Synthetic Major Ampullate Silk Fibers As Revealed In Silico, Amanda E. Brooks, Shane R. Nelson, Justin A. Jones, Courtney Koenig, Michael Hinman, Michael Hinman, Shane Stricker, Randolph V. Lewis

Biology Faculty Publications

All characterized major ampullate silks from orb-web weaving spiders are composites of primarily two different proteins: MaSp1 and MaSp2. The conserved association of MaSp1 and MaSp2 in these spider species, the highly conserved amino acid motifs, and variable ratios of MaSp1 to MaSp2 demonstrate the importance of both MaSp1 and MaSp2 to the strength and elasticity of the fiber. Computer simulated mechanical tests predicted differing roles for MaSp1 and MaSp2 in the mechanical properties of the fibers. Recombinant MaSp1 and MaSp2 proteins were blended and spun into fibers mimicking the computer-simulated conditions. Mechanical testing verified the differing roles of MaSp1 …

Rapid Satellite Deployment Of A Consumer Electronics Payload, Marit Meyer

Small Satellite Conference

Currently, launching a satellite into orbit is plausible only for organizations with multi-million dollar budgets and requires three or more years for development and qualification. Small satellites traveling as secondary payloads on regularly scheduled launches provide access to space at a fraction of the cost and in a fraction of the time. However, a modular adaptable satellite container can significantly reduce cost and development schedule. By sealing and pressurizing the container to maintain an earthlike environment in orbit, a payload of unmodified terrestrial electronics can be integrated and launched in a matter of weeks. Such a container, SCUTE (Sealed Container …

Cellular-Satellite, A Different Kind Of Final Frontier, James Lyke, Robert Pugh

Small Satellite Conference

Extending the ideas of reconfigurable components and self-organizing, plug-and-play systems offer some very intriguing prospects for rapid satellites of the future. In this talk, we describe the “cellular satellite” as a paradigm for the ultimately modular and rapidly formed system. In this vision, all systems are formed as a vast ensemble of black-box cells, each of which is individually customizable to collectively form an integral system. Locally (within a given cell), all significant functions and properties (e.g., electrical, thermal, and mechanical) are softwaredefinable, similar in principle to the approaches used in ordinary field programmable gate arrays but extended far beyond …

Genomic Profiling Reveals An Alternate Mechanism For Hepatic Tumor Promotion By Perfluorooctanoic Acid In Rainbow Trout, Susan C. Tilton, Gayle A. Orner, Abby D. Benninghoff, Hillary M. Carpenter, Jerry D. Hendricks, Cliff B. Pereira, David E. Williams

Animal, Dairy, and Veterinary Science Faculty Publications

Background

Perfluorooctanoic acid (PFOA) is a potent hepatocarcinogen and peroxisome proliferator (PP) in rodents. Humans are not susceptible to peroxisome proliferation and are considered refractory to carcinogenesis by PPs. Previous studies with rainbow trout indicate they are also insensitive to peroxisome proliferation by the PP dehydroepiandrosterone (DHEA), but are still susceptible to enhanced hepatocarcinogenesis after chronic exposure.

Objectives

In this study, we used trout as a unique in vivo tumor model to study the potential for PFOA carcinogenesis in the absence of peroxisome proliferation compared with the structurally diverse PPs clofibrate (CLOF) and DHEA. Mechanisms of carcinogenesis were identified from …
