Biophysical Characterization Of A Beta-Peptide Bundle: Comparison To Natural Proteins, E. James Petersson, Cody J. Craig, Douglas S. Daniels, Jade X. Qiu, Alanna S. Schepartz

Chemistry Faculty Publications

We recently described the high-resolution X-ray structure of a helical bundle composed of eight copies of the β-peptide Zwit-1F. Like many proteins in Nature, the Zwit-1F octamer contains parallel and antiparallel helices, extensive inter-helical electrostatic interactions, and a solvent-excluded hydrophobic core. Here we explore the stability of the Zwit-1F octamer using circular dichroism (CD) spectroscopy, analytical ultracentrifugation (AU), differential scanning calorimetry (DSC), and NMR. These studies demonstrate that the thermodynamic and kinetic properties of Zwit-1F closely resemble those of α-helical bundle proteins. Together these studies should provide a model for the design of β-peptide proteins with biological functions.

Contributions Of Family Leisure To Family Functioning Among Families That Include Children With Developmental Disabilities, Dorthy Clara Hornberger Dodd

Theses and Dissertations

The purpose of this study was to examine the relationship between family leisure involvement and family functioning among families that include children with developmental disabilities. The sample consisted of 154 families (154 parents and 62 youth). Data were analyzed from the parent, youth, and family perspective. The Family Leisure Activity Profile (FLAP) was used to measure family leisure involvement. FACES II was used to measure family functioning. A scale based upon the definition, classification, and systems of support manual of the American Association on Mental Retardation adapted by Dyches was used to measure the level of support needed by the …

Haplotype Association Between Haptoglobin (Hp2) And Hp Promoter Snp (A-61c) May Explain Previous Controversy Of Haptoglobin And Malaria Protection, Sharon E. Cox, Conor Doherty, Sarah H. Atkinson, Chidi V. Nweneka, Anthony J.C. Fulford, Hala Ghattas Ph.D., Kirk A. Rockett, Dominic P. Kwiatkowski, Andrew M. Prentice

Faculty Publications

Background

Malaria is one of the strongest recent selective pressures on the human genome, as evidenced by the high levels of varying haemoglobinopathies in human populations–despite the increased risk of mortality in the homozygous states. Previously, functional polymorphisms of Hp, coded by the co-dominant alleles Hp1 and Hp2, have been variously associated with several infectious diseases, including malaria susceptibility.

Methodology/Principal Findings

Risk of a clinical malarial episode over the course of a malarial transmission season was assessed using active surveillance in a cohort of Gambian children aged 10–72 months. We report for the first time that the major haplotype for …

Novel Polymer-Metal Nanocomposites For Applications In Detection And Sensing, Dayling L. Chaparro

USF Tampa Graduate Theses and Dissertations

Detection of trace elements such as organic contaminants, explosive residues, and metal ions is an intellectually challenging task in science and engineering. It is also a topic of increasing importance due to its impact on society and the environment. Designing molecularly imprinted materials is one of the most promising approaches to explore sensing and detection applications. “Stimuli-sensitive” polymer materials are ideal candidates for these imprinted sensors as they are able to respond to changes in their environment and can be tailored by cross-linking the polymer chains. The responses can be amplified and transduced into measurable signals due to macromolecular properties …

Growth Factor-Mediated Telomerase Activity In Ovarian Cancer Cells, Yira Bermudez

USF Tampa Graduate Theses and Dissertations

Ovarian cancer is the leading cause of gynecological cancer death in the United States. Even though no single genetic alteration can be attributed to all ovarian cancers, 90% of ovarian tumors express telomerase, a ribonucleoprotein that elongates telomeric (TTAGGG)n repeats de novo. In normal somatic cells, telomerase is absent. In cancer cells, the re-expression of telomerase allows senescence to be bypassed contributing to cellular immortalization, a key step for cellular transformation, making telomerase a potentially important target for therapeutic intervention.

Ovarian cancer cells secrete vascular endothelial growth factor (VEGF) and lysophosphatidic acid (LPA) that feedback through their receptors present …

Structure-Function Studies Of Conserved Sequence Motifs Of Cytochrome B5 Reductase:, Louis J. Crowley

USF Tampa Graduate Theses and Dissertations

NADH:Cytochrome b₅ Reductase (cb₅r) catalyzes the two electron reduction of the iron center of the heme cofactor found within cytochrome b₅ (cb₅) utilizing reducing equivalents of the nicotinamide adenine dinucleotide (NADH) coenzyme. Cb₅r is characterized by two domains necessary for proper enzyme function: a flavin-binding domain and a pyridine nucleotide-binding domain. Within these domains are highly conserved "motifs" necessary for the proper binding and orientation of both the NADH coenzyme and the FAD cofactor.

To address the importance of these conserved motifs site-directed mutagenesis was utilized to generate a …

The Association Between Risk Taking And Personality, Gabriella Anic

USF Tampa Graduate Theses and Dissertations

The aim of this study was to examine the association between personality and risk taking in a sample of 461 older adults from the Charlotte County Healthy Aging Study (CCHAS). The personality factors of openness to experience, extraversion, neuroticism, agreeableness and conscientiousness were measured with the NEO Five Factor Inventory. Risk-taking was measured with an 8-item questionnaire and a single-item question that assessed subjects' participation in sensation seeking behaviors. Spearman correlation coefficients, hierarchical linear regression and hierarchical logistic regression were used to assess the association. As consistent with past research, high scores on openness to experience (beta = 0.16, P<.0001) and low scores on neuroticism (β = -0.14, P<.01) and agreeableness (β = -0.16, P<.01) were associated with the total score of the 8-item risk taking questionnaire. The single-item risk question was also associated with openness [OR = 1.09; 95% CI: 1.05-1.13], neuroticism [OR = 0.94; 95% CI: 0.90-0.97] and agreeableness [OR = 0.95; 95% CI: 0.92-0.99]. After stratifying by gender, only openness was still significantly associated with risk-taking. Interaction terms including gender and personality factors were added to the models to test if gender was an effect modifier. Although personality differences existed between men and women, none of the interaction terms were statistically significant.

What Is The Best Reference Rna? And Other Questions Regarding The Design And Analysis Of Two-Color Microarray Experiments, Kathleen F. Kerr, Kyle A. Serikawa, Caimiao Wei, Mette A. Peters, Roger E. Bumgarner

UW Biostatistics Working Paper Series

The reference design is a practical and popular choice for microarray studies using two-color platforms. In the reference design, the reference RNA uses half of all array resources, leading investigators to ask: What is the best reference RNA? We propose a novel method for evaluating reference RNAs and present the results of an experiment that was specially designed to evaluate three common choices of reference RNA. We found no compelling evidence in favor of any particular reference. In particular, a commercial reference showed no advantage in our data. Our experimental design also enabled a new way to test the effectiveness …

Palmitoylation Of The Cysteine-Rich Endodomain Of The Sars-Coronavirus Spike Glycoprotein Is Important For Spike-Mediated Cell Fusion, Chad M. Petit, Vladimir N. Chouljenko, Arun Iyer, Robin Colgrove, Michael Farzan, David M. Knipe, K. G. Kousoulas

Faculty Publications

The SARS-coronavirus (SARS-CoV) is the etiological agent of the severe acute respiratory syndrome (SARS). The SARS-CoV spike (S) glycoprotein mediates membrane fusion events during virus entry and virus-induced cell-to-cell fusion. The cytoplasmic portion of the S glycoprotein contains four cysteine-rich amino acid clusters. Individual cysteine clusters were altered via cysteine-to-alanine amino acid replacement and the modified S glycoproteins were tested for their transport to cell-surfaces and ability to cause cell fusion in transient transfection assays. Mutagenesis of the cysteine cluster I, located immediately proximal to the predicted transmembrane, domain did not appreciably reduce cell-surface expression, although S-mediated cell fusion was …

Factors Influencing Zooplankton Distribution In The Chesapeake And Delaware Bays, Pia Marie Paulone

Undergraduate University Honors Capstones

The Chesapeake and Delaware Bays are well known and extensively studied for their commercial value and environmental quality. There have been multiple studies based on salinity and temperature in these bays, but little is known about the influence of these factors on zooplankton distribution. Salinity has an effect on physiological processes, and, as a result, species have adapted for certain salinities. Temperature impacts both species physiology and primary productivity, which, in turn, impacts feeding rates of zooplankton. Based on previous studies on zooplankton distribution and current knowledge of physical variables, it was expected that salinity is the major variable in …
