They are a heterogeneous population composed of various phenotype. These phenotypes have specific functions characteristic of valve physiological and pathological conditions. The effect of mechanical loading and chemical modulators on the behavior of the valve interstitial cells have largely been studied. However the role of valve interstitial cell shape as an intrinsic physical cue …

Leptin Regulates The Expression Of Autophagy-Related Genes In Chickens, Peter Olawale Ishola

Graduate Theses and Dissertations

Autophagy or cellular self-digestion, a lysosomal degradation pathway that is conserved from yeast to human, plays a key role in recycling cellular constituents, including damaged organelles. It also plays a pivotal role in the adaptation of cells to a plethora of distinct stressors including starvation. Autophagy has been extensively studied in mammals and yeast, but little is known in avian species. Thus, the major objective of the present study was to determine the effects of leptin on autophagy-related genes in chicken hypothalamus, muscle and liver. Leptin is an adipocytokine that is mostly produced by white adipose cells in mammals (as …

Stink Bugs: Spatial Distribution, Pecan Phenological Susceptibility And Sampling Program, Brian Cowell

Graduate Theses and Dissertations

An effective management program for stink bugs (SBs) in pecan groves requires knowledge of: stages of the pecans susceptible to SB damage; strata of the tree with SB damaged nuts; a practical SB monitoring method; and, effects of landscapes contributing SBs into pecan groves.

Stink bugs produced feeding punctures in pecan shucks at all phenological stages. Pecans punctured before the dough stage drop from the tree. Kernel damage occurs in the pecans’ dough stage, whereas mature pecans are not damaged.

The pecans collected from the whole tree using the tree shaker had significantly less punctures than the pecans collected from …

The Origins Of Legislation, Ganesh Sitaraman

Notre Dame Law Review

Although legislation is at the center of legal debates on statutory interpretation, administrative law, and delegation, little is known about how legislation is actually drafted. If scholars pay any attention to Congress at all, they tend to focus on what happens after legislation is introduced, ignoring how the draft came to exist in the first place. In other words, they focus on the legislative process, not the drafting process. The result is that our account of Congress, the legislative process, and the administrative state is impoverished, and debates in statutory interpretation and administrative law are incomplete. This Article seeks to …

Paratransgenic Control Of Pierce's Disease, Arinder K. Arora

Biology ETDs

Pierce's Disease (PD) is a deadly grapevine disease, which is caused by a Gram negative bacterium, Xylella fastidiosa and transmitted by leafhoppers commonly known as sharpshooters, including the glassy-winged sharpshooter (GWSS, Homalodisca vitripennis). We developed paratransgenic control of PD using a commensal bacterium Pantoea agglomerans E325. The GWSSs acquired enhanced green fluorescent (EGFP)-expressing P. agglomerans from an artificial feeding system and the bacteria persisted within the insect foregut for two weeks. P. agglomerans was selected as the paratransgenic control agent based on its persistence within the sharpshooter foregut, a niche also inhabited by X. fastidiosa. P. agglomerans lines secreting two …

R-Ketorolac Targets Cdc42 And Rac1 And Alters Ovarian Cancer Behaviors Critical For Invasion And Metastasis, Yuna Guo

Biomedical Sciences ETDs

Cdc42 (cell division control protein 42) and Rac1 (Ras-related C3 botulinum) are attractive therapeutic targets in ovarian cancer based on their established importance in tumor cell migration, adhesion and invasion. Despite a predicted benefit, targeting GTPases has not yet been translated to clinical practice. Based on lead identification through high-throughput screening and computational shape homology approaches, R-ketorolac is identified as a Cdc42 and Rac1 regulator, an activity that is distinct from the anti-inflammatory, cyclooxygenase inhibitory activity of S-ketorolac. In this dissertation, R-ketorolac is established as an allosteric inhibitor of Cdc42 and Rac1. Studies on immortalized human ovarian adenocarcinoma cells (SKOV3ip), …

Apolipoprotein B Containing Lipoproteins Contribute To Host Innate Immune Pulmonary Defense Against Staphylococcus Aureus, Brett Manifold-Wheeler

Biomedical Sciences ETDs

Circulating lipoproteins are increasingly recognized as innate immune effector molecules. Severe hypolipidemia, which may occur with trauma or critical illness, is clinically associated with bacterial pneumonia. Importantly, pneumonia caused by Staphylococcus aureus is a major cause of morbidity and mortality in both hospital- and community-acquired pneumonia cases. Here we report that lipoprotein deficiency impairs early pulmonary innate defense against S. aureus quorum-sensing dependent pathogenesis. Specifically, apoB levels in the lung early post-infection are significantly reduced with lipoprotein deficiency, coinciding with impaired host control of S. aureus agr-signaling and increased agr-dependent morbidity and inflammation. Given that lipoproteins also inhibit LTA- and …

With the objective of promoting active lifestyles, this paper presents an agent system that provides recommendations of suitable ADL plans (i.e., selected ADL sequences) to individual users based on the more active lifestyles of the others. Specifically, we develop a set of quantitative measures, named wellness scores, spanning the evaluation across the physical, cognitive, emotion, and social aspects based on his or her ADL routines. Then we propose an ADL sequence learning model, named Recommendation ADL ART, or …

Modeling Social Media Content With Word Vectors For Recommendation, Ying Ding, Jing Jiang

Research Collection School Of Computing and Information Systems

In social media, recommender systems are becoming more and more important. Different techniques have been designed for recommendations under various scenarios, but many of them do not use user-generated content, which potentially reflects users’ opinions and interests. Although a few studies have tried to combine user-generated content with rating or adoption data, they mostly reply on lexical similarity to calculate textual similarity. However, in social media, a diverse range of words is used. This renders the traditional ways of calculating textual similarity ineffective. In this work, we apply vector representation of words to measure the semantic similarity between text. We …

Active Crowdsourcing For Annotation, Shuji Hao, Chunyan Miao, Steven C. H. Hoi, Peilin Zhao

Research Collection School Of Computing and Information Systems

Crowdsourcing has shown great potential in obtaining large-scale and cheap labels for different tasks. However, obtaining reliable labels is challenging due to several reasons, such as noisy annotators, limited budget and so on. The state-of-the-art approaches, either suffer in some noisy scenarios, or rely on unlimited resources to acquire reliable labels. In this article, we adopt the learning with expert~(AKA worker in crowdsourcing) advice framework to robustly infer accurate labels by considering the reliability of each worker. However, in order to accurately predict the reliability of each worker, traditional learning with expert advice will consult with external oracles~(AKA domain experts) …

Overt And Covert Shandyism Of Nabokov's Nikolai Gogol, Margarit Ordukhanyan

CLCWeb: Comparative Literature and Culture

In her article "Overt and Covert Shandyism of Nabokov's Nikolai Gogol" Margarit Ordukhanyan examines Vladimir Nabokov's 1942 novel, an unusual biography of the nineteenth-century Russian author. Ordukhanyan discusses parallels between Nabokov's biography of Gogol and Laurence Sterne's Life and Opinions of Tristram Shandy. She highlights the direct allusions and textual references Nabokov makes to Sterne's novel and argues that Nabokov uses Tristram Shandy as the model for creating and interpreting his biography of Gogol by fictionalizing Gogol and portraying him as a Shandean character. Further, Ordukhanyan discusses how Nabokov uses Sterne's novel to undermine the genre of literary …
