Using Stable Isotope Analysis Of Zooplankton To Document Trophic And Biogeochemical Changes In The San Francisco Estuary, Steven C. Westbrook, Julien Moderan

STAR Program Research Presentations

Zooplankton represent a vital link between phytoplankton and fish, like the endangered Delta Smelt. Human interferences (nitrates from waste water, flow alteration, invasive species introduction…) have altered the structure of the San Francisco Estuary (SFE) ecosystem. We use stable isotope analysis to improve our knowledge of the planktonic food web in the SFE and gain insights into its evolution over the past decades. We use the ratios of certain isotopes (Nitrogen, Carbon, Sulfur, etc.) in different species of zooplankton to tell us what it is feeding on as well as the trophic level it feeds in. My research focused on …

Protein-Protein Interactions In The Neocortex: Emx2 And Its Binding Partners, Cierra Miller

Undergraduate Honors Theses

The mammalian neocortex is divided into discrete functional areas that are marked by distinct boundaries and whose positions are assigned through a process called neocortical arealization. One of the proteins involved in this process is Emx2, a transcription factor (protein that turns genes on and off) that is expressed, or made, in a gradient along the axis of the neocortex and determines the positions of these areal boundaries. In order to determine how Emx2 carries out this function of assigning areas, we have identified the proteins QKl-7 and Cnot61 as binding partners of Emx2.

Current research involves confirming the interactions …

Method Development For A Chemical And Biological Analysis Of Glucocorticoids In Wastewater, Maria Carmen Lozano

Open Access Theses & Dissertations

Glucocorticoids are a class of steroid hormones that can either be produced synthetically or naturally by the adrenal glands. The synthetic glucocorticoids are highly prescribed in the United States for their anti-inflammatory and immunosuppressive properties to treat a variety of ailments and diseases; however, these have been implicated in a number of adverse human conditions such as obesity, metabolic syndrome, immune-suppression, delayed puberty, adrenal insufficiency and Cushing Syndrome, among others. Ongoing research has shown that synthetic and natural hormones are transported to aquatic environments via mammalian excretion or wastewater effluent, and as a result, the release of glucocorticoids into the …

Silver Nanoparticles Induce Developmental Stage-Specific Embryonic Phenotypes In Zebrafish, Kerry J. Lee, Lauren M. Browning, Prakash D. Nallathamby, Christopher J. Osgood, Xiao-Hong Nancy Xu

Chemistry & Biochemistry Faculty Publications

Much is anticipated from the development and deployment of nanomaterials in biological organisms, but concerns remain regarding their biocompatibility and target specificity. Here we report our study of the transport, biocompatibility and toxicity of purified and stable silver nanoparticles (Ag NPs, 13.1 ± 2.5 nm in diameter) upon the specific developmental stages of zebrafish embryos using single NP plasmonic spectroscopy. We find that single Ag NPs passively diffuse into five different developmental stages of embryos (cleavage, early-gastrula, early-segmentation, late-segmentation, and hatching stages), showing stage-independent diffusion modes and diffusion coefficients. Notably, the Ag NPs induce distinctive stage and dose-dependent phenotypes and …

Molecularly Imprinted Polymer Technology: A Powerful, Generic, Facile And Cost Effective Alternative For Enantio-Recognition And Separation: A Glance At Advances And Applications, Jyn Philip, Dms Mosha

Tanzania Journal of Science

The emerging Molecularly Imprinted Polymer (MIP) technology has yielded proof of concept, harnessing nature’s fundamentals to yield recognition receptor mimics from the miniaturized basics, borrowing on the ground rules, but conveniently avoiding the complexity, fragility, instability, costs and ethics of animal based bio-affinity matrices. Thus, the impact of bio-sciences on the future of technology is not via direct use of the molecules, but rather the lessons learned. Molecular imprinting is a powerful specialty representing the generic, cost effective and facile alternative for preparation of synthetic custom-tailored receptors. It achieves this via creation of specific selective recognition sites for a pre-determined …

The Lyme Disease Spirochete In Tick Species Collected From Warren County, Kentucky, Cheryl C. Onwu

Mahurin Honors College Capstone Experience/Thesis Projects

The overall goal of this present study was to determine the prevalence of the Lyme disease spirochete, Borrelia burgdorferi, in south central Kentucky. A survey of ticks collected from a single location in Warren County, Kentucky was conducted between the months of April and June, 2010. A total of 293 ticks were collected. Three species were identified: 264 (91.7 %) of the ticks were Amblyoma americanum, 18 (6.6%) were Dermacentor variabilis, and 1 (0.35%) was Ixodes scapularis. The ten remaining ticks were immature nymphs and could not be identified. After identifying the species and sex of …

Oxaliplatin And Oxaliplatin Derivatives: Synthesis, Characterization, And Reactivity With Biologically Relevant Ligands, Amy Poynter

Mahurin Honors College Capstone Experience/Thesis Projects

Oxaliplatin is a third generation anticancer drug that has proven to be successful in fighting ovarian and testicular cancer. We are interested in determining how oxaliplatin and oxaliplatin derivatives interact with proteins, as well as how that interaction is affected by the size and shape of these platinum compounds. We have synthesized oxaliplatin as it is used in cancer treatment, as well as similar platinum compounds with the same diaminocyclohexane ligand as oxaliplatin but with additional bulk added to the nitrogen atoms. We are reacting oxaliplatin with key amino acids, including methionine, and will be comparing the kinetics of this …

Investigation Of Autoregulation Of Icer And Electrochemical Properties Of Tryptophan, Mark Demilio

Theses, Dissertations and Culminating Projects

A relatively new development in the field of research-based chemistry is to study biomolecules, their interactions, and a biochemical mechanisms by examination of their physical properties and application of laboratory techniques rooted in concepts of physical chemistry. Both projects that are encompassed within this master's thesis indeed fall under the umbrella of biophysical chemistry, as they apply physical chemical techniques study particular biomolecular interactions.

The first of these two projects is the study of a leucine zipper protein, Inducible cAMP Early Repressor [ICER], which is a product of the cAMP Responsive Element Modulator [CREM] gene. ICER functions as a transcriptional …

Biomass Assisted Synthesis Of Antibacterial Gold Nanoparticles And Commentary On Its Future Potential And Applications In Medicine, Chad Willis

Mahurin Honors College Capstone Experience/Thesis Projects

Xylose is a natural monosaccharide found in biomass such as straw, pecan shells, cottonseed hulls, and corncobs. Using this monosaccharide, we report the green synthesis and characterization of biocompatible, biodegradable xylose encapsulated gold nanoparticles (Xyl-GNPs) with potential antibacterial activity. GNPs were synthesized using the bioreduction property of xylose on the chloroaurate anions in an aqueous solution at room temperature and at atmospheric pressure. The characterization of synthesized GNPs was examined by UV-vis spectroscopy; transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS) and fourier transform infrared spectroscopy (FTIR). Results indicate that the particles were stable; near spherical in shape with an …

The Influence Of Aliphatic Side Chain Of Anacardic Acid On Molecular Recognition Properties Of Imprinted Polymers, Jyn Philip, J Buchweishaija, Ll Mkayula, L Ye

Tanzania Journal of Science

The objective of this work was to determine the influence of the aliphatic side chain of anacardic acid on molecular recognition properties of imprinted polymers made from anacardanyl methacrylate (AnMcr). Salicylic methacrylate (SaMcr), a structural analog of AnMcr, was synthesized and used as a functional monomer to prepare imprinted polymers for comparison with AnMcr-based polymers. Using divinylbenzene (DVB) as a cross linker and racemic propranolol as a model template, irregular monolithic particles of poly(SaMcr-co-DVB)m were synthesized in toluene, and spherical beads of poly(SaMcr-co-DVB)b and poly(AnMcr-co-DVB)b weresynthesized in acetonitrile by precipitation polymerization. Although imprinted irregular monolithic particles, poly(SaMcr-co-DVB)m, tested in toluene …

Early Lqt2 Nonsense Mutation Generates N-Terminally Truncated Herg Channels With Altered Gating Properties By The Reinitiation Of Translation, Matthew R. Stump, Qiuming Gong, Jonathan D. Packer, Zhengfeng Zhou

Faculty Publications - Department of Biological & Molecular Science

Mutations in the human ether-a-go-go-related gene (hERG) result in long QT syndrome type 2 (LQT2). The hERG gene encodes a K+ channel that contributes to the repolarization of the cardiac action potential. We have previously shown that hERG mRNA transcripts that contain premature termination codon mutations are rapidly degraded by nonsense-mediated mRNA decay (NMD). In this study, we identified a LQT2 nonsense mutation, Q81X, which escapes degradation by the reinitiation of translation and generates N-terminally truncated channels. RNA analysis of hERG minigenes revealed equivalent levels of wild-type and Q81X mRNA while the mRNA expressed from minigenes containing the LQT2 frameshift …

Isoform-Specific Dominant-Negative Effects Associated With Herg1 G628s Mutation In Long Qt Syndrome, Matthew R. Stump, Qiuming Gong, Zhengfeng Zhou

Faculty Publications - Department of Biological & Molecular Science

Background: Mutations in the human ether-a-go-go-related gene 1 (hERG1) cause type 2 long QT syndrome (LQT2). The hERG1 gene encodes a K+ channel with properties similar to the rapidly activating delayed rectifying K+ current in the heart. Several hERG1 isoforms with unique structural and functional properties have been identified. To date, the pathogenic mechanisms of LQT2 mutations have been predominantly described in the context of the hERG1a isoform. In the present study, we investigated the functional consequences of the LQT2 mutation G628S in the hERG1b and hERG1aUSO isoforms.

Methods: A double-stable, mammalian expression system was developed to characterize …

Plants Of The Western United States: Expanding The Collection And Biological Testing Of Extracts, Fernando N. Galvan

Undergraduate Honors Theses

The goal of this research was to find compounds with the potential for use as medicines. Many microorganisms use a mechanism known as active efflux to move antibiotics out of cells. As a result, the effectiveness of antibiotics may be partially or completely reduced allowing the pathogen to survive. A major theme of this research was to look for compounds in plants that inhibit active efflux processes and that are related to multi-drug resistance. After the diffusion of an antibiotic into a bacterial cell, an efflux pump inhibitor may prevent the antibiotic from being expelled from the organism, leading to …
