D-Galactose Decreases Mitoneet Levels In Liver Cancer Cells: Impact On Cellular Bioenergetics, Sudip Paudel

Masters Theses

Galactose is a simple sugar that at supraphysiological concentrations accelerates aging and age-related complications, which lead to impaired mitochondrial functions. MitoNEET is a small mitochondrial membrane protein with a molecular mass of 12.2 kDa that functions in diabetes, iron metabolism, regulation of oxidative phosphorylation (OXPHOS) and reactive oxygen species (ROS) homeostasis. MitoNEET knockdown increases cellular respiration rates and ROS levels similar to galactose treatment. Pioglitazone, an antidiabetic drug, binds to mitoNEET and ameliorates galactose toxicity. Cellular mitoNEET levels, exposure of cells to galactose medium, and pioglitazone treatment directly influence cellular respiration. To elucidate the role of mitoNEET in galactose induced …

Attention Regulation, Emotion Regulation, And Cognitive Flexibility As Mediators Of The Relationship Between Mindfulness And Academic Achievement In High School Students, Andrew Baginski

Masters Theses

Mindfulness is defined as a process of purposefully paying attention to one’s thoughts, feelings, and experiences in the present moment while taking a nonjudgmental stance on them (Kabat-Zinn, 2009). While originally an Eastern approach technique in spirituality and philosophy, mindfulness has been incorporated into or served as a basis for numerous psychological therapies and treatments (Segal, Williams, & Teasdale, 2002; Kabat-Zinn, 1982, 1990). Research into mindfulness has expanded to the context of learning, where studies have demonstrated that facilitative states of mindfulness can improve the abilities of students to focus, attend, and recall information in an educational setting (Langer, 1997). …

In this quasi-experimentally designed study, a convenience sample of diners (N=35) served as subjects. The experimental group (n=18) was offered a to-go box before the meal, and the control group (n=17) was offered a to-go box after the meal. The food was …

The Lyric And The Lathe: Dreams Of Perfect Poetic Efficiency, 1800-1917, Steven A. Nathaniel

Masters Theses

This study examines patterns of efficiency in the poetry and theory of William Wordsworth, Hilda Doolittle, and other figures from the Modernist and Romantic periods. I begin by defining perfect efficiency as occurring when energy transforms, without loss, inside a closed energy system, and I offer perpetual motion machines as hypothetical examples of this impossible state. I then demonstrate the process of efficiency in William Wordsworth's poetry, which begins with circumlocutory poetic cycles but contracts into terse repetitions. Since technical efficiency is calculated by the formula output/input, poetry's subjectivity makes poetic efficiency difficult to measure. However, I suggest that repetitions …

Computer Aided Detection Of Oral Lesions On Ct Images, Shaikat Mahmood Galib

Masters Theses

"Oral lesions are important findings on computed tomography images. They are difficult to detect on CT images because of low contrast, arbitrary orientation of objects, complicated topology and lack of clear lines indicating lesions. In this thesis, a fully automatic method to detect oral lesions from dental CT images is proposed to identify (1) Closed boundary lesions and (2) Bone deformation lesions. Two algorithms were developed to recognize these two types of lesions, which cover most of the lesion types that can be found on CT images. The results were validated using a dataset of 52 patients. Using non training …

Damage Detection Through Acoustic Emission Of Fracture Processes In Concrete Masonry Units, John Alexander Cain

Masters Theses

"Masonry structures are vulnerable to earthquakes; their brittleness and discontinuous formation make them susceptible to collapse. In the event of an emergency, this could be detrimental and perhaps fatal. The area of Structural Health Monitoring (SHM) is focused on understanding the behavior of structures for the sake of safety and predicting their longevity. One applicable technique to monitor this behavior is Acoustic Emission (AE). Acoustic Emissions are transient elastic waves released as microcracks nucleate from stress intensities, coalesce into cracks and then accumulate as damage. AE monitoring is a favorable method because it is capable of detecting cracking from within …

For this purpose, excited frequency is calculated such that it excites the second order longitude mode. In order to investigate the behavior of emitted wave in …

Rote-Lcs Learning Classifier System For Classification And Prediction, Benjamin Daniels

Masters Theses

"Machine Learning (ML) involves the use of computer algorithms to solve for approximate solutions to problems with large, complex search spaces. Such problems have no known solution method, and search spaces too large to allow brute force search to be feasible. Evolutionary algorithms (EA) are a subset of machine learning algorithms which simulate fundamental concepts of evolution. EAs do not guarantee a perfect solution, but rather facilitate convergence to a solution of which the accuracy depends on a given EA's learning architecture and the dynamics of the problem.

Learning classifier systems (LCS) are algorithms comprising a subset of EAs. The …

Ph Dependent Antibiotic Resistance Of An Alkaliphilic, Halotolerant Bacterium Isolated From Soap Lake, Washington, Tiffany Charlynn Edwards

Masters Theses

"Soap Lake, located in Washington State, is a meromictic, soda lake. Many bacterial isolates retrieved from Soap Lake have been noted to possess resistance to multiple antibiotics. A likely explanation for the wide range of antibacterial resistance exhibited by these strains is due to the impact of high alkalinity on the antibiotics themselves and not due to the presence of antibiotic resistance genes. The aim of our study was to determine if select antibiotics are effective against Halomonas eurialkalitoleranis, a bacterium capable of growth over a wide range of neutral to alkaline pH values, to investigate the influence of alkalinity …

Sensitivity Of Cellular Oxidative Damage To Biosynthetic Rate And Metabolic Rate, Palihawadana Walauwe Kamalika Kaushalya Amunugama

Masters Theses

"The relationship between energy expenditure and longevity is a long standing question in aging studies. The empirical results have contradictory effects on the existing theories. A theoretical model and an experimental test of it were presented, revealing the detailed tradeoffs between metabolic rate, biosynthetic rate and cellular damage level. The dissipative mechanisms of oxidative metabolism cause various forms of cellular damages. To counteract the accumulation of damage, organisms have evolved highly efficient maintenance mechanisms. If there is no other energy demand possess, then most of the cellular damage would be repaired, regardless of how metabolic rate varies. However, the repairing …
