Image Restoration Using Automatic Damaged Regions Detection And Machine Learning-Based Inpainting Technique, Chloe Martin-King

Computational and Data Sciences (PhD) Dissertations

In this dissertation we propose two novel image restoration schemes. The first pertains to automatic detection of damaged regions in old photographs and digital images of cracked paintings. In cases when inpainting mask generation cannot be completely automatic, our detection algorithm facilitates precise mask creation, particularly useful for images containing damage that is tedious to annotate or difficult to geometrically define. The main contribution of this dissertation is the development and utilization of a new inpainting technique, region hiding, to repair a single image by training a convolutional neural network on various transformations of that image. Region hiding is also …

Chemical Epitope Targeting: Review Of A Novel Screening Technology, Qurrat Ul-Ain, Rene Kandler, Dylan Gillespie, Arundhati Nag

Scholarly Undergraduate Research Journal at Clark (SURJ)

Chemical Epitope Targeting is a novel technology developed for designing peptide ligands with high affinity and specificity against specific regions of a protein that may be inaccessible to small molecules or antibodies. In this review, we summarize the key steps and significant applications of this technology. Operating on the same principles as antibody-antigen interactions, this technique involves chemically synthesizing the region of interest on the protein, called the epitope, as a polypeptide with a biotin detection tag and a strategically placed alkyne or azide presenting amino acid. The constructed epitope is screened against a comprehensive linear or cyclic One Bead …

The Relationship Between Socioeconomic Status And White Matter Microstructure In Pre-Reading Children: A Longitudinal Investigation, Ola Ozernov-Palchik, Elizabeth S. Norton, Yingying Wang, Sara D. Beach, Jennifer Zuk, Maryanne Wolf, John D.E. Gabrieli, Nadine Gaab

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Reading is a learned skill crucial for educational attainment. Children from families of lower socioeconomic status (SES) tend to have poorer reading performance and this gap widens across years of schooling. Reading relies on the orchestration of multiple neural systems integrated via specific white-matter pathways, but there is limited understanding about whether these pathways relate differentially to reading performance depending on SES background. Kindergarten white-matter FA and second-grade reading outcomes were investigated in an SES-diverse sample of 125 children. The three left-hemisphere white-matter tracts most associated with reading, and their right-hemisphere homologs, were examined: arcuate fasciculus (AF), superior longitudinal fasciculus …

A Microfluidics-Based Cross-Flow Filtration Platform For Rapid Processing Of Amphiphilic Biomarkers From Blood, Kiersten D. Lenz

Biomedical Engineering ETDs

Early and accurate detection of bacterial infections can help save lives, prevent the spread of disease, and decrease the overuse of antibiotics. Our team at the Los Alamos National Laboratory has developed novel assays to detect bacterial biomarkers from patient blood at the point-of-care in order to facilitate a universal diagnostic platform. However, these biomarkers are amphiphilic in nature, and this biochemical property causes them to be sequestered by high-density and low-density lipoproteins (HDL and LDL) in the host’s blood. Extraction of the bacterial biomarkers from the lipoprotein complexes is thereby required for the development and deployment of a diagnostic …

In Vitro Evaluation Of Ovarian Cancer Tumorigenesis As A Function Of Quinone Oxidoreducatse-1 And Cell Phenotype, Milcah S. Jackson

LSU Doctoral Dissertations

In vitro multicellular spheroids are attractive model systems for assessing genetic and epigenetic changes that occur in diseased tissues. Understanding how such alterations in gene and subsequent protein expression affect disease progression and metastasis, drug resistance, and recurrence is of great interest in cancer research. In this regard, examining expression and activity of proteins, such as those with cytoprotective ability that are overexpressed in cancer cells, in addition to cell phenotype (i.e., stem-like, epithelial, mesenchymal, or mixed), are two ways to evaluate genetic and epigenetic changes. Moreover, determining the impact that cytoprotective proteins and cell phenotype have on tumor formation …

Evaluation Of The Role Of Microvascular Pathology On Peripheral Artery Disease, Constance Mietus

Theses & Dissertations

Background: Peripheral Artery Disease (PAD) begins with atherosclerotic narrowing of arteries, including those that supply the legs. Individuals with PAD experience pain during walking, which becomes increasingly limiting. Studies from our group and others have shown that a myopathy is present in the skeletal muscle of PAD patients, and is characterized by myofiber degeneration, fibrosis, and remodeling of vessels ranging from 50 – 150 mm in diameter. However, microvascular pathology, particularly of the smallest microvessels (5 – 15 mm in diameter) remains poorly characterized. Furthermore, little is known about the relationships between microvascular architecture, microperfusion, and patient walking performance. We …

Omt For The Treatment Of Depression And Anxiety, Zachary Winchell

Rowan-Virtua Research Day

Osteopathic manipulative therapy (OMT) fundamentally aims to remedy somatic dysfunction through the manipulation of the patient. In this regard, OMT is a particularly viable non-pharmacological adjunct for patients with depressive and generalized anxiety disorder (GAD).

In both of these disorders, the hypothalamic-pituitary-adrenal axis has an interdependent relationship with physiological stress that feed one another to both increase symptomology and leave patients vulnerable to negative life events. Additionally, pro-inflammatory cytokines acting on the brain over long periods of time can lead to exacerbation of disease and the development of depression in susceptible individuals. Altered cytokine balance has also been found in …

Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre

Honors Scholar Theses

Abnormal ocular motility is a common manifestation of many underlying pathologies particularly those that are neurological. Dynamics of saccades, when the eye rapidly changes its point of fixation, have been characterized for many neurological disorders including concussions, traumatic brain injuries (TBI), and Parkinson’s disease. However, widespread saccade analysis for diagnostic and research purposes requires the recognition of certain eye movement parameters. Key information such as velocity and duration must be determined from data based on a wide set of patients’ characteristics that may range in eye shapes and iris, hair and skin pigmentation [36]. Previous work on saccade analysis has …
