The Relationship Between Seasonal Breeding And Deiodinase Expression In The Green Anole Lizard, Hyejoo Kang

All Graduate Theses, Dissertations, and Other Capstone Projects

Reproductive physiology and behavior is mainly regulated by the hypothalamus-pituitary-gonad (HPG) axis. Interestingly, abnormal levels of thyroid hormone (TH) results in the delayed onset of puberty and affects gonadal function of adults by altering HPG axis activity. Seasonally breeding animals undergo drastic hormonal and behavioral changes between breeding and non-breeding seasons. Green anole lizards (Anolis carolinensis), similar to other seasonally breeding animals, have increased sex steroid hormones, larger gonads, upregulated gonadal steroidogenic acute regulatory protein (StAR) mRNA and increased reproductive behavior during the breeding compared to non-breeding seasons. Relatively less is known regarding the regulation of gonadal TH in seasonal …

Amino Acids Profiling For The Diagnosis Of Metabolic Disorders, Yana Sandlers

Chemistry Faculty Publications

Inborn errors of metabolism (IEM) represent a group of inherited diseases in which genetic defect leads to the block on a metabolic pathway, resulting in a single enzyme dysfunction. As a downstream consequence of the residual or full loss of the enzymatic activity, there is an accumulation of toxic metabolites in the proximity of the metabolic block and/or a deficiency of an essential metabolic product which leads to the clinical presentation of the disease. While individually IEMs are rare, a collectively estimated incidence of metabolic inherited disorders is 1:800. The genetic basis of IEMs can involve abnormalities such as point …

Unintended Consequences Of Dna Analysis Delays In North Carolina, Pamela Cook Woodard

Walden Dissertations and Doctoral Studies

The processing of DNA recovered from felony crime scenes often causes delays in trials of up to 3 years, calling into question defendants' rights to a speedy trial. Using Lewin's force field analysis as the theoretical framework, the purpose of this quantitative, comparative study was to compare the processing and reporting of results related to DNA testing in 4 states. Survey data were collected from state bar members (n=137), members of a professional law organization (n=149), and members of a state DNA laboratory (n=20). The purpose of this quantitative, comparative study was to determine whether these variables (interagency communications, staff …

Toward An Enzyme-Coupled, Bioorthogonal Platform For Methyltransferases: Probing The Specificity Of Methionine Adenosyltransferases, Tyler D. Huber

Theses and Dissertations--Pharmacy

Methyl group transfer from S-adenosyl-l-methionine (AdoMet) to various substrates including DNA, proteins, and natural products (NPs), is accomplished by methyltransferases (MTs). Analogs of AdoMet, bearing an alternative S-alkyl group can be exploited, in the context of an array of wild-type MT-catalyzed reactions, to differentially alkylate DNA, proteins, and NPs. This technology provides a means to elucidate MT targets by the MT-mediated installation of chemoselective handles from AdoMet analogs to biologically relevant molecules and affords researchers a fresh route to diversify NP scaffolds by permitting the differential alkylation of chemical sites vulnerable to NP MTs that are unreactive to …

Biology: Faculty Publications

River ecosystems receive and process vast quantities of terrestrial organic carbon, the fate of which depends strongly on microbial activity. Variation in and controls of processing rates, however, are poorly characterized at the global scale. In response, we used a peer-sourced research network and a highly standardized carbon processing assay to conduct a global-scale field experiment in greater than 1000 river and riparian sites. We found that Earth’s biomes have distinct carbon processing signatures. Slow processing is evident across latitudes, whereas rapid rates are restricted to lower latitudes. Both the mean rate and variability decline with latitude, suggesting temperature constraints …

Elucidating A Common Mechanism Of Proteasome Impairment In Neurodegenerative Disease And Its Pharmacological Intervention, Tiffany Ann Thibaudeau

Graduate Theses, Dissertations, and Problem Reports (ETD)

Proteostasis is maintained by several systems in the cell including the ubiquitin-proteasome system (UPS), chaperones, chaperone-mediated autophagy, and macroautophagy. The UPS is the principle route for the degradation of intracellular misfolded, damaged, or unneeded cellular proteins and has a critical role essential every cell process, including: cell cycle progression, transcriptional regulation, genome integrity, apoptosis, immune responses, and neuronal plasticity. When the efficiency of protein degradation is perturbed, misfolded and damaged protein aggregates can accumulate to toxic levels and cause neuronal dysfunction, which may underlie many neurodegenerative diseases. It is widely appreciated that soluble oligomers of misfolded proteins (e.g. Aβ, Alzheimer’s; …

The Effects Of Heat-Killed Echinostomatid Parasites On Mice Treated With Dextran Sodium Sulfate (Dss), Natalie Gooder

All Graduate Theses, Dissertations, and Other Capstone Projects

Objective: Autoimmune diseases are chronic, incurable, and affect approximately 50 million Americans. This is a strong need for better ways to treat autoimmune diseases. Parasites and parasite proteins have been observed to protect mice from symptoms of induced colitis in mice treated with dextran sodium sulfate (DSS), a model for inflammatory bowel disease (IBD). I hypothesize that non-living echinostomatid parasites, given during DSS treatment, can decrease intestinal inflammation and weight loss, providing a possible novel treatment for IBD.

Methods: A range of DSS concentrations (0.5%-3%) were delivered to female C57BL/6 mice in their drinking water in order to determine the …

Decadal Biomass Increment In Early Secondary Succession Woody Ecosystems Is Increased By Co2 Enrichment, Anthony Walker, Martin G. De Kauwe, Blinda E. Medlyn, Sonke Zaehle, Colleen M. Iversen, Shinichi Asao, Bertrand Guenet, Anna Harper, Tonas Hickler, Bruce A. Hungate, Atul K. Jain, Yiqi Luo, Xingjie Lu, Meng Lu, Kristina Luus, J. Patrick Megonigal, Ram Oren, Edmund Ryan, Shijie Shu, Alan Talhelm, Ying-Ping Wang, Jeffrey M. Warren, Christian Werner, Jianyang Xia, Bai Yang, Donald R. Zak, Richard J. Norby

Articles

Increasing atmospheric CO2 stimulates photosynthesis which can increase net primary production (NPP), but at longer timescales may not necessarily increase plant biomass. Here we analyse the four decade-long CO2-enrichment experiments in woody ecosystems that measured total NPP and biomass. CO2 enrichment increased biomass increment by 1.05 ± 0.26 kg C m−2 over a full decade, a 29.1 ± 11.7% stimulation of biomass gain in these early-secondary-succession temperate ecosystems. This response is predictable by combining the CO2 response of NPP (0.16 ± 0.03 kg C m−2 y−1) and the CO2-independent, linear slope between biomass increment and cumulative NPP (0.55 ± 0.17). …

MET is a receptor tyrosine kinase (RTK) that plays important roles in carcinogenesis. Despite being frequently overexpressed in cancer, clinical responses to targeting this receptor have been limited. Recently novel splicing mutations involving the loss of exon 14 (called METex14 skipping) have emerged as potential biomarkers to predict for responsiveness to targeted therapies with Met inhibitors in non-small cell lung cancer (NSCLC). Currently, the diverse genomic alterations responsible for METex14 skipping pose a challenge for routine clinical diagnostic testing. In this report, we examine three different methodologies to detect METex14 and assess their potential utility for use as a diagnostic …

The aim of the study was to verify the effects of dart weight and target distance on kinematic variables of the movement control of the underarm dart throwing task. Four women and one man performed the task of throwing a dart at two horizontal circular targets located at 2m (Nt) and 3m (Ft) away, with two different weights, 22g (Ld) and 44g (Hd). On the first phase of the experiment, the human volunteers performed 200 trials per day during four sessions. On the fifth day, it had 40 more trials in a pseudo random order that were recorded and analysed. …

Effects Of Hydrogen Synthesis Inhibition On Changes Of Bioproduct Contents In Cyanobacterium Synechocystis Sp. Pcc 6803, Nannaphat Sukkasam

Chulalongkorn University Theses and Dissertations (Chula ETD)

Cyanobacteria have an ability to convert carbon dioxide and solar light to bioproducts. Synechocystis sp. PCC 6803 is the laboratory model strain of cyanobacteria with known metabolism and biochemistry. NADPH is one of the essential electron carriers and coenzymes required for various cellular metabolism including the production of bioproducts. [NiFe]-Hydrogenase consumes NADPH to produce hydrogen gas which considerably the loss of metabolic energy. Thus, the elimination of [NiFe]-hydrogenase would increase NADPH level in the cell and might increase the accumulation of bioproducts. In this work, hoxY and hoxH genes (encoding the two catalysis subunits of [NiFe]-hydrogenase) were inactivated. The inactivation …

Anti-Tumor Activities Of Auricularia Polytricha Extracts In Hepatocellular Carcinoma Cell Line (Hepg2) And Breast Cancer Cell Lines (Mcf-7 And Mda-Mb-231), Sunita Nilkhet

Chulalongkorn University Theses and Dissertations (Chula ETD)

Cancer is the disease that happens to occur in a high number of new cases each year. Even the choice of treatment is developing, but the adverse effects on cancer therapeutic drugs still challenging. To investigate the antitumor activities of Auricularia polytricha (AP) mushroom extract and active compounds, human cancer cell lines such as Hepatocellcular (HepG2) and Breast cancer cell lines (MCF-7 and MDA-MB-231) were interested. The crude hexane extract of AP (APH) and crude ethanol extract of AP (APE) were prepared by maceration and Soxhlet extraction, respectively. Both APE and APH were investigated for their compound compositions by GC-MS. …

To breed improved biomass cultivars of Miscanthus ×giganteus, it will be necessary to select the highest‐yielding and best‐adapted genotypes of its parental species, Miscanthus sinensis and Miscanthus sacchariflorus. We phenotyped a diverse clonally propagated panel of 569 M. sinensis and nine natural diploid M. ×giganteus at one subtropical (Zhuji, China) and five temperate locations (Sapporo, Japan; Leamington, Ontario, Canada; Fort Collins, CO; Urbana, IL; and Chuncheon, Korea) for dry biomass yield and 14 yield‐component traits, in trials grown for 3 years. Notably, dry biomass yield of four Miscanthus accessions exceeded 80 Mg/ha in Zhuji, China, approaching …

An Arabidopsis Protoplast Isolation Method Reduces Cytosolic Acidification And Activation Of The Chloroplast Stress Sensor Sensitive To Freezing 2, Allison C. Barnes, Christian G. Elowsky, Rebecca Roston

Department of Biochemistry: Faculty Publications

Chloroplasts adapt to freezing and other abiotic stresses in part by modifying their membranes. One key-remodeling enzyme is SENSITIVE TO FREEZING2 (SFR2). SFR2 is unusual because it does not respond to initial cold stress or cold acclimation, instead it responds during freezing conditions in Arabidopsis. This response has been shown to be sensitive to cytosolic acidification. The unique lipid products of SFR2 have also been detected in response to non-freezing stresses, but what causes SFR2 to respond in these stresses is unknown. Here, we investigate protoplast isolation as a representative of wounding stress. We show that SFR2 oligogalactolipid products accumulate …

Ehdv-2 Infection Prevalence Varies In Culicoides Sonorensis After Feeding On Infected White-Tailed Deer Over The Course Of Viremia, Sandra Y. Mendiola, Mary K. Mills, Elin Maki, Barbara S. Drolet, William C. Wilson, Roy D. Berghaus, David E. Stallknecht, Jonathan Breitenbach, D. Scott Mcvey, Mark G. Ruder

School of Veterinary and Biomedical Sciences: Faculty Publications

Epizootic hemorrhagic disease viruses (EHDVs) are arboviral pathogens of white-tailed deer and other wild and domestic ruminants in North America. Transmitted by various species of Culicoides, EHDVs circulate wherever competent vectors and susceptible ruminant host populations co-exist. The impact of variation in the level and duration of EHDV viremia in white-tailed deer (Odocoileus virginianus) on Culicoides infection prevalence is not well characterized. Here we examined how infection prevalence in a confirmed North American vector of EHDV-2 (Culicoides sonorensis) varies in response to fluctuations in deer viremia. To accomplish this, five white-tailed deer were experimentally infected with EHDV-2 and colonized C. …

The Impact Of Household Biocides And Antibiotics On Aquatic Microbial Community Composition, Abdulaziz Saud M Alrashdi

Dissertations, Master's Theses and Master's Reports

Triclosan (TCS) is antimicrobial agent that is used in a lot of consumer products, including toothpaste, liquid and bar soap, and cosmetics. TCS has been found in many lakes and rivers in the United States. However, The Food and Drug Administration (FDA) banned TCS recently and it will no longer be used in household products. Despite the recent ban, TCS is known to persist in the environment and may have long-term impacts. We conducted an experiment on using fresh water from three locations Houghton, Green Bay and the Huron Mountains. Our goals in the study is to assess the impact …

Preparation Of A Perylenebisimide Acceptor With Serinol And Nonadecyl-Swallowtail Imides For Use In Molecular Rectification, Tarrah Frederick

Honors Theses

Several attempts were made to add 2-amino-1,3-propanediol to the acceptor perylene monoanhydride (PMA). The theoretical product, N-(10-nonadecyl)-N'-(1,3-dihydroxypropan-2-yl)perylene-3,4,9,10-bis(dicarboximide), is intended for use in unimolecular rectification because the perylenebisimide core is classified as a good acceptor due to its high electron affinity. Rectification usually utilizes donor-σ-acceptor molecules, whose localized orbitals permit electron transfer when placed between metal electrodes of asymmetric voltages. However, according to an “asymmetric rectification” analysis, an electron can pass from one electrode, through the LUMO of the acceptor, and then to the other electrode when said electrodes are held at certain voltages, and result in rectification if the acceptor …

Carbon Dioxide Reduction Using Redox-Active Macrocyclic Catalysts, Dawson Kendall Buettner

Honors Theses

The current energy crisis experienced by society today is in desperate need of a solution. Through carbon dioxide (CO2) reduction, we can reduce the amount of greenhouse gas that is warming our planet as well as create a source of renewable energy. Significant challenges currently inhibit the reduction of CO2 to more desirable products. Current limitations can be addressed through the design and synthesis of more efficient catalysts that are selective, durable, and operate close to the target thermodynamic potential of CO2 reduction. In this work, three redox-active macrocyclic ligands have been synthesized and studied for the development of potential …

Cullin-3 Dependent Deregulation Of Actn1 Represents A New Pathogenic Mechanism In Nemaline Myopathy, Jordan Blondelle, Kavya Tallapaka, Jane T. Seto, Majid Ghassemian, Madison Clark, Jenni M. Laitila, Adam Bournazos, Jeffrey Singer, Stephan Lange

Biology Faculty Publications and Presentations

Nemaline myopathy is a congenital neuromuscular disorder characterized by muscle weakness, fiber atrophy, and presence of nemaline bodies within myofibers. However, understanding of the underlying pathomechanisms is lacking. Recently, mutations in KBTBD13, KLHL40, and KLHL41, three substrate adaptors for the E3 ubiquitin ligase Cullin-3, have been associated with early-onset nemaline myopathies. We hypothesized that deregulation of Cullin-3 and its muscle protein substrates may be responsible for disease development. Using Cullin-3–knockout mice, we identified accumulation of non-muscle α-actinins (ACTN1 and ACTN4) in muscles of these mice, which we also observed in patients with mutations in KBTBD13. Our …

Mutations Of Fus Cause Aggregation Of Rna Binding Proteins, Disruptions In Protein Synthesis, And Dysregulation Of Nonsense Mediated Decay, Marisa Elizabeth Kamelgarn

Theses and Dissertations--Toxicology and Cancer Biology

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by motor neuron death and subsequent muscle atrophy. Approximately 15% of ALS cases are inheritable, and mutations in the Fused in Sarcoma (FUS) gene contribute to approximately 5% of these cases, as well as about 2% of sporadic cases. FUS performs a diverse set of cellular functions, including being a major regulator of RNA metabolism. FUS undergoes liquid- liquid phase transition in vitro, allowing for its participation in stress granules and RNA transport granules. Phase transition also contributes to the formation of cytoplasmic inclusions found in the …

Some extractive components have biological activities with medical applications. They also play important roles in wood processing and related applications. To increase the knowledge of wood chemistry, maple and oak were extracted by water. Ultraviolet/visible (UV/vis) spectroscopy indicated the presence of a phenolic compound, resorcinol, in maple extractives having higher molecular mass and more aromatic components than oak extractives. Negative and positive electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR-MS) identified thousands of formulas in the two …

Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …

Condensation And Polymerization Explain The Humification Of Lignin Into Aliphatic And Aromatic Structures In Soil, Patrick G. Hatcher, Hongmei Chen, Seyyedhadi Khatami, Derek C. Waggoner

Chemistry & Biochemistry Faculty Publications

Soil organic matter (SOM) constitutes a global reservoir of carbon that is more than twice that of either atmospheric carbon or aquatic carbon; however, the manner in which it forms from degraded plant biomass is poorly understood. Some have recently questioned whether plant biomass is involved directly in SOM formation and suggest that it is microbial carbon that constitutes the main source of stable SOM. Such a view implies that above and below ground plant biomass is rapidly decomposed and mineralized. This view contrasts significantly with traditional ones that involve the transformation of plant biomass to recalcitrant humic materials fueled …

Treatment Of Plastic Wastes Using Plasma Gasification Technology, Zachary Homolka

Honors Program: Senior Projects (Public)

Plasma gasification (PG) complements traditional recycling when applied to contaminated or mixed plastics. Without PG these plastics cost recyclers more to process than they are worth on the market, and sometimes they are landfilled or incinerated instead of being recycled. Plasma gasification can take plastic not suitable for traditional recycling and break it down into high-quality syngas for use in electricity generation, chemical manufacturing, or hydrogen production. The technology can be implemented without changing the behavior of consumers, which is a major advantage over attempting to decrease contamination or reduce use of low-value plastic. Due to high capital requirements and …

Identification Of Antibiotic Ge37468a From Pseudonocardia Symbionts Of Trachymyrmex Septentrionalis Ants, Krithika Rao

Scripps Senior Theses

In response to the growing rates of antibiotic resistance in human bacterial pathogens, this study explores the natural products involved in the defensive symbiosis between actinobacteria and fungus-growing ants to uncover new potential antibiotics. This study also seeks to understand the function of natural antibiotics in their ecological contexts, especially those involved in defensive symbioses. Defensive symbiosis can be a beneficial platform for discovering useful antibiotics, because antibiotics in these relationships must be able to selectively inhibit enemies without harming hosts, and are therefore likely more specific and less toxic. Pseudonocardia sp. associated with Trachymyrmex septentrionalis ants demonstrated antibiotic activity …

Effect Of Osteoactivin And Bone Morphogenetic Protein-2 On Soft Tissue In Rat Spinal Fusion Model, Andrew Ohliger

Williams Honors College, Honors Research Projects

Osteoinductive therapeutic strategies are essential for the bone healing process and are applicable in multiple orthopaedic procedures. The novel protein Osteoactivin (OA) has proven to stimulate osteoblast differentiation and function in vitro and bone regeneration in vivo in the rat model. More recently, OA has shown significant bone regeneration ability in sheep. The goal of this study is the comparison of osteoactivin with bone morphogenetic protein-2 (BMP-2) in the rat spinal fusion model.

Computational Study Of Disease Related Proteins Form Electrostatic Point Of View, Chitra Bahadur Karki

Open Access Theses & Dissertations

In the last three decades, many giant DNA viruses have been discovered. The giant viruses present a unique and essential research frontier for the study of self-assembly and regulation of supramolecular assemblies. The question on how these giant DNA viruses assemble thousands of proteins so accurately to form their protein shell, the capsids, remains largely unanswered. Revealing the mechanisms of giant virus assembly will help to discover the mysteries of many self-assembly biology problems. Paramecium Bursaria Chlorella Virus 1 (PBCV-1) is one of the most intensively studied giant viruses. Based on the high-resolution structure of PBCV-1, we implemented a multi-scale …

Protein Templated Silver Nanoclusters, Greyson Keel

Honors Theses

Nanoclusters are smaller than their nanoparticle counterparts and have unique properties. Most research has been done on gold nanoclusters, but silver nanoclusters are said to be more robust. During the process of trying to create nanoclusters, several methods in the procedure were changed when gathering data: determining a successful silver concentration, working with the correct buffer, mixing gold and silver metals together, observing the effects of pH, and finding a good reducing agent. After experimenting with those changes, a successful protocol was adapted and modified from literature (Journal of Materials Chemistry, 2011, 21, 11205-11212) to produce the protein-templated Ag clusters. …
