Shear-Induced Aggregation And Ordering Of Amylopectin Dispersion Affected By Hydrocolloids, Fang Fang

Open Access Dissertations

Amylopectin is a naturally highly-branched biomacromolecule. Amylopectin molecules with re-ordered structure have high viscosity and viscoelastic properties that may have potentially good nutritional functions such as providing long-lasting energy to the human body and delaying stomach empty among other properties. However, the amylopectin molecular re-ordering process under static conditions normally takes much longer time than amylose to achieve a desired and relatively stable structure. A simple but novel approach consisting in applying a constant shear rate of 20 s-1 at a temperature of 5oC for 24 hours was proposed in this study to accelerate the re-ordering process of gelatinized waxy …

Development Of Novel Proteomic Strategies To Dissect Plant Phosphoproteomic Signaling Under Environmental Stresses, Chuan-Chih Hsu

Open Access Dissertations

Protein phosphorylation is one of the important signaling mechanisms in plants which transduces environmental stimuli such as salinity, microbes, and hormones into intracellular signals and activates plant defense mechanisms. Thus, understanding the correlation between environmental stresses and alteration of plant phosphorylation requires system-wide phosphoproteomic analysis, which includes identification of kinase-substrate complexes and measurement of phosphorylation-mediated signaling changes. However, identification and quantification of plant phosphoproteome remains challenging due to the highly dynamic nature of plant proteome, interferences of cell wall, pigments, and secondary metabolites. Recently, mass spectrometry (MS) has been integrated with phosphopeptide enrichment approaches for identifying thousands of phosphorylation sites …

Intravascular Photoacoustic Imaging Of Lipid-Laden Plaque: From Fundamental Concept Towards Clinical Translation, Jie Hui

Open Access Dissertations

Atherosclerosis is the major form of cardiovascular disease, which has been the number one cause of death in the United States and worldwide for a century. Among the different plaque types, vulnerable plaques account for the majority of fatal acute coronary syndromes due to their rupture and thrombosis. Currently, there are no clinically available imaging tools to reliably and accurately detect vulnerable plaques largely due to the lack of chemical selectivity. This gap, along with the increasing prevalence of coronary artery diseases, highlight an unmet clinical need for an imaging modality with both chemical selectivity and enough depth resolution to …

Quality By Design In Twin Screw Granulation, Shankali U. Pradhan

Open Access Dissertations

Granulation is often used as a size enlargement unit operation in various solid handling and powder processing industries such as pharmaceuticals, foods, detergents, catalysts, and particulate chemicals. Granulation helps to mitigate issues related to poor flowability, dust hazards, and powder segregation. Traditionally, granulation has been performed in the batch mode of operation. More recently, the United States Food and Drug Administration is encouraging manufacturers to adopt continuous processing due its several advantages over batch manufacturing. Twin screw granulation is therefore becoming increasingly relevant due to its compact size, continuous and robust mode of operation, flexible and customizable design, and flexible …

Brain Energy Homeostasis And The Regulation Of N-Acetyl-Aspartate Metabolism In Development And Disease, Samantha Zaroff

Graduate School of Biomedical Sciences Theses and Dissertations

N-acetylaspartate (NAA) is a non-invasive clinical marker of neuronal metabolic integrity because of its strong proton magnetic resonance spectroscopy (H-MRS) peak and direct correlation with energetic integrity. Specifically, NAA is used to track the progression of neurodegenerative diseases due to the characteristic reduction of whole brain levels of NAA which occur simultaneously with reduced glucose utilization and mitochondrial dysfunction, but prior to the onset of disease specific pathology. However, NAA will also significantly increase simultaneously with energetic integrity during periods of recovery or remission in applicable disorders, such as traumatic brain injuries. Unfortunately, it remains enigmatic exactly why NAA is …

Profitability Analysis Of Varying Herd Sizes Based On Price Signals In Cow-Calf Operations, Colson Tester

Agricultural Economics and Agribusiness Undergraduate Honors Theses

The third most consumed meat around the world is beef. Despite global growth in demand, cattle markets experience price cycles related to biological production lags causing variability in cash flow and profitability for producers. Price-driven herd size management strategies thus have received attention. This study adds to that literature by analyzing both price and production risk using three herd size management strategies: i) steady state – holding herd size constant; ii) dollar cost averaging – keeping reinvestment constant by varying the number of replacement heifers retained at a constant long run average dollar total; and iii) moving average – using …

Cognitive Behavioral Therapy Is Associated With Enhanced Cognitive Control Network Activity In Major Depression And Posttraumatic Stress Disorder, Zhen Yang, Desmond Oathes, Kristin Linn, Steven Bruce, Theodore Satterthwaite, Philip Cook, Emma Satchell, Haochang Shou, Yvette Sheline

Psychology Faculty Works

BACKGROUND: Both major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are characterized by depressive symptoms, abnormalities in brain regions important for cognitive control, and response to cognitive behavioral therapy (CBT). However, whether a common neural mechanism underlies CBT response across diagnoses is unknown. METHODS: Brain activity during a cognitive control task was measured using functional magnetic resonance imaging in 104 participants: 28 patients with MDD, 53 patients with PTSD, and 23 healthy control subjects; depression and anxiety symptoms were determined on the same day. A patient subset (n = 31) entered manualized CBT and, along with controls (n = …

A Neuroprotective Role For Mir-1017, A Non-Canonical Mirna, Matthew De Cruz

Master's Theses

miRNAs are post-transcriptional regulators of gene expression, with numerous being involved in neurobiology. Within the human genome a quarter of the identified miRNA loci derive from a class of miRNAs termed tailed mirtrons. Despite the identification of this large population of miRNA, no functional studies have been conducted to identify their role. In this study we examined the highly expressed and deeply conserved Drosophila 3’ tail mirtron, miR-1017, as a candidate to elucidate tailed mirtron functionality. We identified acetylcholine receptor transcripts, Da5 and Da2, as bona fide targets for miR-1017. Interestingly, Da2 is also the host transcript for miR-1017. We …

Stabilization Of Hypoxia Inducible Factor By Cobalt Chloride Can Alter Renal Epithelial Transport, Subhra Nag, Andrew Resnick

Physics Faculty Publications

© 2017 The Authors. Given the importance of the transcriptional regulator hypoxia-inducible factor-1 (HIF-1) for adaptive hypoxia responses, we examined the effect of stabilized HIF-1α on renal epithelial permeability and directed sodium transport. This study was motivated by histological analysis of cystic kidneys showing increased expression levels of HIF-1α and HIF-2α. We hypothesize that compression induced localized ischemia-hypoxia of normal epithelia near a cyst leads to local stabilization of HIF-1α, leading to altered transepithelial transport that encourages cyst expansion. We found that stabilized HIF-1α alters both transcellular and paracellular transport through renal epithelial monolayers in a manner consistent with secretory …

Using Eye-Tracking And Molecular Modeling To Explore Students’ Strategies For Solving Organic Stereochemical Problems, Travis Howard Knowles

Dissertations

Stereochemistry concepts are often some of the most difficult topics for students to grasp in the organic chemistry curriculum. Several factors may influence students’ abilities to solve stereochemistry problems, including their spatial abilities, strategy choice, and ability to use various types of spatial representations. A mixed-method study was conducted to investigate the role that these factors play when novice organic chemistry students solve stereochemistry problems. Eye-tracking methods were used in an attempt to capture cognitive processes of students while solving these problems. Additionally, three-dimensional molecular models and spatial ability measures were used to further analyze and characterize their strategies for …

Testing The Limits Of Temporal Stability: Willingness To Pay Values Among Grand Canyon Whitewater Boaters Across Decades, Christopher J. Neher, John Duffield, Lucas Bair, David Patterson, Katherine Neher

Mathematical Sciences Faculty Publications

We directly compare trip willingness to pay (WTP) values between 1985 and 2015 stated preference surveys of private party Grand Canyon boaters using identically designed valuation methods. The temporal gap of 30 years between these two studies is well beyond that of any tests of WTP temporal stability in the literature. Comparisons were made of mean WTP estimates for four hypothetical Colorado River flow level scenarios. WTP values from the 1985 survey were adjusted to 2015 levels using the consumer price index. Mean WTP precision was estimated through simulation. No statistically significant differences were detected between the adjusted Bishop et …

Graphene Field Effect Transistors For Highly Sensitive And Selective Detection Of K+ Ions, Hongmei Li, Yihao Zhu, Md. Sayful Islam, Md. Anisur Rahman, Kenneth B. Walsh, Goutam Koley

Publications

Graphene-based ion sensitive field effect transistors (GISFETs) with high sensitivity and selectivity for K+ ion detection have been demonstrated utilizing valinomycin based ion selective membrane. The performance of the GISFETs for K+ ion detection was studied in various media over a concentration range of 1 μM–2 mM. The sensitivity of the sensor was found to be >60 mV/decade, which is comparable to the best Si-based commercial ISFETs, with negligible interference found from Na+ and Ca2+ ions in high concentration. The sensor performance did not change significantly in Tris–HCl solution or with repeated testing over a period of two months highlighting …

Extended Lamer Synthesis Of Cobalt Doped Ferrite, Benjamin D. Fellows, Sarah Sandler, Jacob Livingston, Kristin Fuller, Lotanna Nwandu, Sarah Timmis, Kayla A. Lantz, Morgan Stefik, O. Thompson Mefford

Publications

Nonstoichiometric cobalt ferrite nanoparticles have drawn interest in magnetically mediated energy delivery due to their high magnetocrystalline anisotropy and their high peak loss frequency. The use of an extended LaMer synthesis allows for size control of the doped particles up to a threshold core diameter of 18 nm. Above this diameter, particles become unstable and drop out of suspension, allowing for further nucleation events to occur. This leads to a cyclic nucleation, growth, and destabilization regime seen during the course of the reaction. Using the size control of the extended LaMer synthesis technique, we examine the specific absorption rate (SAR) …

Subanesthetic Ketamine For Postoperative Analgesia: An Evidenced-Based Project, Jeremy Vance

Doctoral Projects

Roughly 100 million surgical procedures are performed in the United States (U.S.) each year and more than 80% of these patients experience acute postoperative pain. Pain costs the U.S. an estimated $560 to $635 billion annually and is a significant contributor to national rates of mortality, morbidity, and disability. Despite these findings, patients continue to receive suboptimal postoperative pain relief.

The adjunct administration of subanesthetic ketamine is opioid-sparing and can improve the effectiveness of a multimodal pain management approach. This project used an exploratory descriptive design to examine how an evidence-based presentation impacted the clinical practice of certified registered nurse …
