BACKGROUND: Gestational diabetes mellitus (GDM) is one of most common complications of pregnancy, with incidence rates varying by maternal age, race/ethnicity, obesity, parity, and family history. Given its increasing prevalence in recent decades, covariant environmental and sociodemographic factors may be additional determinants of GDM occurrence. OBJECTIVE: We hypothesized that environmental risk factors, in particular measures of the food environment, may be a diabetes contributor. We employed geospatial modeling in a populous US county to characterize the association of the relative availability of fast food restaurants and supermarkets to GDM. STUDY DESIGN: Utilizing a perinatal database with >4900 encoded antenatal and …

Journal of Applied Research on Children: Informing Policy for Children at Risk
A recent series of emails and phone calls from parents concerned about the sugar content of Houston Independent School District’s school breakfasts revealed that a new issue had risen to the surface. This prompted us to look closely at the sugar content of our breakfast items. School districts participating in the National School Breakfast Program follow a strict set of nutritional regulations set forth by the USDA under the Healthy Hunger Free Kids Act (HHFKA) of 2010 in response to the childhood obesity epidemic. HHFKA made significant changes to the breakfast meal pattern, but did not set standards for the …

Literacy: Varied, Dynamic, And Multidimensional, Stephen B. Kucer Dr.
Journal of Family Strengths
This article examines the complex nature of literacy through a variety of lenses. The linguistic lens focuses on literacy as a language and multimodal process. The cognitive reveals the mental processes and strategies readers and writers employ to construct meanings through the linguistic and multimodal dimension. Not just a linguistic and cognitive process, the sociocultural lens examines literacy use within social and cultural contexts. Finally, the developmental lens explores the very active nature of literacy learners and their mediators.

"What Is Essential Is Invisible To The Eye": Culturally Responsive Teaching As A Key To Unlocking Children's Multiple Literacies, Shanna Peeples
Journal of Family Strengths
Refugee students, language learners, and students in poverty are often viewed through a deficit model of everything they do not have in the way of school preparedness. However, many of them are survivors who possess courage and resilience. They also possess exceptional visual literacy developed through experiences with video and other images. Leveraging their visual literacy builds a bridge to help them understand text, which in turn helps them understand how literature reflects all of our experiences. Increased textual literacy helps students engage with vexing human questions. These questions form an inquiry base from which students can approach writing as …
Promoting Health Literacy For People With Disabilities And Clinicians Through A Teamwork Model, David W. Hollar Jr., Jennifer Rowland
Promoting Health Literacy For People With Disabilities And Clinicians Through A Teamwork Model, David W. Hollar Jr., Jennifer Rowland
Journal of Family Strengths
Current health literacy programs for people with disabilities lack clear operational definitions, rely on inconsistent health literacy statistics, and tend to follow a medical model approach that often fallaciously assumes people with disabilities have limited health knowledge. The central issue in addressing and improving health literacy among people with disabilities is to focus on clear and effective health communication among health care team members, including people with disabilities, which can ultimately improve this population’s health outcomes. Our proposed teamwork model builds upon the World Health Organization’s International Classification of Functioning, Disability and Health (ICF) biopsychosocial model, decision-making theory, and health …

Trim28 Interacts With Ezh2 To Regulate Its Activity, Jing Li, Jing Li
Trim28 Interacts With Ezh2 To Regulate Its Activity, Jing Li, Jing Li
Dissertations and Theses (Open Access)
In this dissertation, I discovered that TRIM28 interacts with EZH2 and regulates its activity in breast cancer cells. EZH2, the major H3K27 tri-methyltransferase, is over expressed in multiple subtypes of breast cancer; however, whether EZH2 plays an active role in breast cancer progression or treatment resistance is unknown. Here, we determined EZH2-interacting proteins in MCF7 cells by immunoprecipitation/mass spectrometry and detected TRIM28 with a high confidence score. TRIM28 is a transcription co-regulator with an N-terminal tri-partite RING finger, B-boxes and a coiled-coil domain (RBCC) and a C-terminal PHD/Bromo domain. Domain mapping revealed that the RBCC domain of TRIM28 interacts with …

Targeting Oncogenic Mirnas With Small Molecules For Breast Cancer Therapy, Paloma Del C. Monroig
Dissertations and Theses (Open Access)
The crucial role of microRNAs (miRNAs) in cancer pathobiology has driven the introduction of new drug development approaches such as miRNA inhibition. In order to advance miRNA-therapeutics, there is a need to develop screening strategies that can target tumors in a specific way. Small molecule inhibitors represent an attractive approach to pursue this. However, the absence of molecular structures for most of the miRNAs makes it very difficult to predict which inhibitors can bind to them. Herein we designed a strategy to screen for small molecules by assesing whether they could directly bind/ interact with miR-10b/miR-21. As part of our …
Plasmacytoid Dendritic Cell-Mediated Humoral Autoimmunity, Stephanie M. Dorta-Estremera Ph.D.
Plasmacytoid Dendritic Cell-Mediated Humoral Autoimmunity, Stephanie M. Dorta-Estremera Ph.D.
Dissertations and Theses (Open Access)
Humoral autoimmunity is characterized by the breakdown of B cell immune tolerance to self-antigens and consequent production of pathogenic autoantibodies. Plasmacytoid dendritic cells (pDCs), a potent type I interferon (IFN-I) producer, have been linked to the pathogenesis of systemic lupus erythematosus (SLE), a prototypic systemic humoral autoimmune disease. However, the cellular events that stimulate the development of humoral autoimmunity as a result of pDC activation have not been characterized. Moreover, the B cell subset(s) responsible for the generation of autoantibodies remains to be clearly identified.
The immunization of DNA-containing amyloids into non-autoimmune mice triggers the activation of pDCs and induction …

Preventing Thymus Involution In K5.Cyclin D1 Transgenic Mice Sustains The Naïve T Cell Compartment With Age, Michelle L. Bolner
Dissertations and Theses (Open Access)
The thymus maintains T cell receptor (TCR) repertoire diversity through perpetual release of self-MHC restricted naive T cells. However, thymus involution during the aging process reduces naïve T cell output, leading to defective immune responsiveness to newly encountered antigens. We have found that early thymus involution precipitates the age-associated shift favoring memory T cell dominancy in young control mice. Furthermore, we have shown that age-related thymus involution is prevented in mice expressing a keratin 5 promoter-driven Cyclin D1 (K5.D1) transgene in thymic epithelial cells (TECs). Thymopoiesis occurs normally in K5.D1 transgenic thymi and sustains T cell output to prevent the …
Investigation Of Quatitative Image Features From Pretreatment Ct And Fdg-Pet Scans In Stage Iii Nsclc Patients Undergoing Defintive Radiation Therapy, David Fried
Dissertations and Theses (Open Access)
The purpose of this work was to determine if quantitative image features (QIFs) extracted from computed tomography (CT) and flourodeoxyglucose (FDG) positron emission tomography (PET) could provide prognostic information to improve outcome models. Our goal for this work was to determine if it may one day be feasible to incorporate QIFs into personalized cancer care. QIFs were used to quantitatively characterize patient disease as seen on imaging. A leave-one-out cross-validation procedure was used to assess the prognostic ability of QIFs extracted from CT and PET in addition to conventional prognostic factors (CPFs). QIFs were found to improve model fit for …

Identifying Protein Kinase Tbk1 As A Novel Inhibitor Of Intestinal Tumorigenesis, Amber L. Mathews
Dissertations and Theses (Open Access)
Colorectal cancer (CRC) is the third most common cancer diagnosed in women and men, causing almost 600,000 annual deaths worldwide. There is a clear need to understand how CRC forms and progresses in order to improve the strategies of CRC prevention and therapy. A major factor that drives the development of CRC is genetic mutations that lead to activation of oncogenes and inactivation of tumor suppressor genes in intestinal epithelial cells (IECs). In addition, the initiation and progression of CRC involve environmental and immunological factors. In particular, chronic inflammatory conditions are known as an important risk factor for CRC. Intestinal …
The Role Of Dna Methylation And Hydroxymethylation In Smooth Muscle Cell Phenotypic Change During Atherogenesis, Jason Williams
The Role Of Dna Methylation And Hydroxymethylation In Smooth Muscle Cell Phenotypic Change During Atherogenesis, Jason Williams
Dissertations and Theses (Open Access)
Atherosclerosis is a chronic arterial disease which impacts systemically the function of organs and tissues by causing inflammation and disruption of blood supply. During atherogenesis, lipid deposits, inflammation, and cells accumulate within the walls of arteries, ultimately leading to a buildup of fatty plaques and occlusion of the arterial lumen. In a multifactorial disease like atherosclerosis there are complex interplays between environmental, genetic and epigenetic risk factors. The epigenetics of atherosclerosis involving DNA methylation has been progressing from single gene to genome wide analyses. Although these epistudies have provided evidence that DNA methylation exists within certain genes during atherogenesis, the …
Prediction Of Laser Ablation In Brain: Sensitivity, Calibration, And Validation, Samuel J. Fahrenholtz
Prediction Of Laser Ablation In Brain: Sensitivity, Calibration, And Validation, Samuel J. Fahrenholtz
Dissertations and Theses (Open Access)
The surgical planning of MR-guided laser induced thermal therapy (MRgLITT) stands to benefit from predictive computational modeling. The dearth of physical model parameter data leads to modeling uncertainty. This work implements a well-accepted framework with three key steps for model-building: model-parameter sensitivity analysis, model calibration, and model validation.
The sensitivity study is via generalized polynomial chaos (gPC) paired with a transient finite element (FEM) model. Uniform probability distribution functions (PDFs) capture the plausible range of values suggested by the literature for five model parameters. The five PDFs are input separately into the FEM model to gain a probabilistic sensitivity response …
Characterization Of Erbb4 Expression In Osteosarcoma, Nupur Lala
Characterization Of Erbb4 Expression In Osteosarcoma, Nupur Lala
Dissertations and Theses (Open Access)
ERBB4 (Her-4) is a member of the ERBB family of Class I receptor tyrosine kinases. ERBB4 is unique within the ERBB family for alternate splicing in its juxtamembrane and cytoplasmic regions, which produces four juxtamembrane isoforms and two cytoplasmic isoforms. The cleavable juxtamembrane isoforms, Jm-a and Jm-d, can undergo proteolytic cleavage and produce an 80-kDa cytoplasmic fragment referred to as “p80,” which has been demonstrated to enhance cellular survival and malignant behavior in many solid tumors [44]. ERBB4 was almost exclusively 80 kDa in size and localized to the nucleus in primary tumors and metastases in studies characterizing ERBB4 expression …
Regulation Of The Oxidative Stress Response By Arid1a, Suet Yan Kwan
Regulation Of The Oxidative Stress Response By Arid1a, Suet Yan Kwan
Dissertations and Theses (Open Access)
SWI/SNF is mutated in about 20% of all human cancers; in particular ARID1A is the most frequently mutated SWI/SNF subunit. ARID1A is a tumor suppressor gene, inactivating mutations in ARID1A are most frequently found in ovarian and endometrial cancers, specifically uterine corpus endometrioid carcinomas (UCEC), ovarian clear cell carcinomas (OCCC) and ovarian endometrioid carcinomas (OEC). The functional roles of ARID1A are not completely understood and there are limited therapeutic strategies that specifically target ARID1A-mutant cancers. Given that ARID1A expression is lost in cancer, ARID1A mutations cannot be targeted directly and novel therapeutic strategies are required to target ARID1A-mutant …

In Vivo Functional Significance Of Ccat2 Long Non-Coding Rna In Myelodysplastic Syndrome, Maitri Y. Shah
Dissertations and Theses (Open Access)
Long non-coding RNAs form the largest part of the mammalian non-coding transcriptome and control gene expression at various levels including chromatin modification, transcriptional and post-transcriptional processing. Although the underlying molecular mechanisms are not yet entirely understood, lncRNAs are implicated in initiation and progression of several cancers. CCAT2 is a lncRNA that spans the highly conserved 8q24 region associated with increased risk for various cancers. CCAT2 has been shown to play an important role in inducing chromosomal instability and supporting cell proliferation and cell cycle arrest. However, a causal role of CCAT2 in initiation of tumorigenesis and the importance of G/T …
Role Of Stat3 In Human Nk Cell Functions, Prasad V. Phatarpekar
Role Of Stat3 In Human Nk Cell Functions, Prasad V. Phatarpekar
Dissertations and Theses (Open Access)
Natural Killer (NK) cells are cytotoxic lymphocytes, which play a critical role in the immune response against malignant cells and microbial infections. NK cells are equipped with activating receptors, which upon detecting ligands expressed on stressed cells induce cytolytic activity of NK cells. Stimulation of NK cell proliferation and priming of NK cytolytic capability are accomplished by cytokines, which mediate their signals mainly through JAK-STAT signaling pathway. Previously, we found that K562 cells genetically modified to express membrane bound IL-21 (mbIL-21), which predominantly activates STAT3, induce robust expansion and activation of human NK cells. Further investigations revealed role of STAT3 …
