Udp-Glucuronosyltransferase (Ugt) Genetic Variants And Their Potential Role In Carcinogenesis, Jean Bendaly

USF Tampa Graduate Theses and Dissertations

Exposure to polycyclic aromatic hydrocarbons (PAHs) such as benzo(a)pyrene are important risk factors for cancer. Three UDP-glucuronosyltransferases, UGT1A9, UGT1A10, and UGT2B7, have been shown to play an important role in the phase II metabolism of carcinogenic metabolites of BaP. Because UGT1A9 and UGT2B7 are well-expressed in digestive tract tissues including liver and colon, it is possible that genetic variations in either enzyme may play an important role in colon cancer risk. However, UGT1A10 is extrahepatic and is expressed in the oral cavity and the larynx; therefore, genetic variations in this enzyme may play an important role in risk for orolaryngeal …

Pressurized Hot Water: An Alternative Method Of Nutrient Extraction And Subsequent Analysis For Use In Small-Scale Agriculture, Kristy Susanne Crane

Theses and Dissertations

Soil analysis for small acreage farms in developing countries is often inconvenient and prohibitively expensive using current procedures, yet the information gained from these soil tests could have economical and environmental benefits. The pressurized hot-water (PHW) extraction coupled with colorimetric or turbidimetric analyses shows promise as an alternative to current procedures. Accepted methods of colorimetric analysis for NO3-N and P exist but an alternative method to atomic absorption spectrometry for K analysis is needed. Of the many possible methods to quantify K, tests performed in the Brigham Young University (BYU) laboratory found sodium tetraphenylborate to be unsatisfactory and sodium cobaltinitrite …

The Application Of Pedology, Stable Carbon Isotope Analyses And Geographic Information Systems To Ancient Soil Resource Investigations At Piedras Negras, Guatemala, Kristofer Dee Johnson

Theses and Dissertations

The ancient inhabitants of the Maya Lowlands enjoyed a long and fruitful period of growth which climaxed at around AD 800. At that time, millions of people successfully subsisted in a challenging environment that today only supports a population a fraction of that size. These facts, and the subsequent "Maya Collapse", are the impetus of many recent studies that utilize environmental data, in addition to conventional archaeology, to investigate this Maya mystery. Pedological studies and stable carbon isotope analysis of soil organic matter, combined with Geographic Information Systems (GIS) are three tools that can be used to answer crucial questions …

Distinguishing Metaphysical From Epistemological Randomness, Andrew Michael Johnson

Theses

The term 'random' is used both popularly and in science in different senses. Randomness sometimes refers to our subjective epistemological inability to discern structure and other times to objective lack of structure in an observed phenomenon. This thesis argues that the best understanding of 'random' should be as a profitable heuristic, similar to imaginary numbers and potential infinities, under the rubric of epistemological randomness (ER). It further argues that positive claims of metaphysical randomness (MR) must be justified by both internality and indeterminacy. Internality acts as a criterion that controls for external causal influences in a given phenomenon. Indeterminacy requires …

Physiological Responses Of Men During The Continuous Use Of A Portable Liquid Cooling Vest, Theresa J. Medina

USF Tampa Graduate Theses and Dissertations

Heat stress is a well documented hazard across industries. The combination of environmental conditions, work demands, and clothing contribute to heat strain. Left unchecked, heat strain causes changes in an individual's physiological state that can lead to serious and fatal conditions with little warning. Although engineering and administrative controls are the first choice to abate this hazard, they frequently are not feasible. In these cases, personal cooling is often employed. There are three main types of personal cooling: liquid, air, and passive. Each has its own advantages and disadvantages.

This study focuses on continuous cooling using a portable liquid cooling …

Learning To Create: A Collection Of Personal Essays, Naomi Lund Christiansen

Theses and Dissertations

This is a creative thesis that focuses on the infertility experiences of the author. The introduction examines the author's justification for choosing personal essay as a genre and French feminism as the guiding theory in writing the essays. Six personal essays center on the author's attempts to have a child and the discoveries and failures along the way. Throughout literary history, women's bodies have traditionally been viewed from the outside looking in, as objects to be reified and preserved or exploited and used. Using the writing the body critics as a theoretical framework, the essays discuss the comforts and discomforts …

The Solution Structure Of The N-Terminal Domain Of Human Vitronectin: Proximal Sites That Regulate Fibrinolysis And Cell Migration, Anand Mayasundari, Neil A. Whittemore, Engin H. Serpersu, Cynthia B. Peterson

Faculty Publications

The three-dimensional structure of an N-terminal fragment comprising the first 51 amino acids from human plasma vitronectin, the somatomedin B (SMB) domain, has been determined by two-dimensional NMR approaches. An average structure was calculated, representing the overall fold from a set of 20 minimized structures. The core residues (18-41) overlay with a root mean square deviation of 2.29 ± 0.62 Å. The N- and C-terminal segments exhibit higher root mean square deviations, reflecting more flexibility in solution and/or fewer long-range NOEs for these regions. Residues 26-30 form a unique single-turn α-helix, the locus where plasminogen activator inhibitor type-1 (PAI-1) is …

A Hydrothermal After-Ripening Time Model Of Seed Dormancy Loss In Bromus Tectorum, Necia Beck Bair

Theses and Dissertations

After-ripening, the process of seed dormancy loss in dry storage is associated with a decrease in the mean base water potential, one of the parameters of hydrothermal time. The rate of change of the mean base water potential is assumed to be a linear function of temperature above a specific base temperature and as a result can be described by a thermal after-ripening (TAR) time model, an extension of hydrothermal modelling. The thermal requirement for after-ripening is the thermal time necessary for the modelling base water potential of the seed to shift from its original value to its final value. …

Feasibility Of Using Nanofiltration As A Polishing Process For Removal Of Cyanobacterial Exudates From Treated Surface Water, Anand J. Mody

USF Tampa Graduate Theses and Dissertations

Nanofiltration (NF) membrane technology is effective for removal of natural organic matter (NOM) and Disinfection By-Product (DBP) precursors from treated surface water (Allgeier et al., 1995, Chellam et al., 2000, Smith et al., 2002). However, there is a need to control other micropollutants, such as compounds released from algal blooms. In this research, the feasibility of using NF for removal of cyanobacterial exudates was evaluated as a polishing process for conventionally treated surface water.

Screening tests were conducted to compare the performance of four NF membranes, Filmtec's NF90 and NF270, and Hydranautics's LFC1 and NTR7450, for removal of NOM and …

Chemical And Biological Investigation Of The Antarctic Red Alga Delisea Pulchra, Santhisree Nandiraju

USF Tampa Graduate Theses and Dissertations

Our interest in the red alga Delisea pulchra (=D.fimbriata) (Greville) Montagne 1844 (Rhodophyceae, Bonnemaisoniales, Bonnemaisoniaceace) was stimulated by its activity in the biosssays done at Wyeth Pharmaceuticals. Halogenated compounds from D. pulchra interfere with Gram-negative bacterial signaling systems, affect the growth of Gram-positive bacteria, inhibit quorum sensing and swarming motility of marine bacteria (inhibit bacterial communication). They also inhibit surface colonization in marine bacteria and exhibit antifouling properties against barnacle larvae and macroalgal gametes.

Chemical investigation of D.pulchra collected near Palmer Station, Antarctica yielded three new dimeric halogenated furanones, pulchralide A-C (41-43), along with previously reported …

Taming The Rugged Landscape: Production, Reordering, And Stabilization Of Selected Cluster Inherent Structures In The X13-NYN System, Dubravko Sabo, J. D. Doll, David L. Freeman

Chemistry Faculty Publications

We present studies of the potential energy landscape of selected binary Lennard-Jones 13 atom clusters. The effect of adding selected impurity atoms to a homogeneous cluster is explored. We analyze the energy landscapes of the studied systems using disconnectivity graphs. The required inherent structures and transition states for the construction of disconnectivity graphs are found by combination of conjugate gradient and eigenvector-following methods. We show that it is possible to controllably induce new structures as well as reorder and stabilize existing structures that are characteristic of higher-lying minima. Moreover, it is shown that the selected structures can have experimentally relevant …

The Kin Composition Of Social Groups: Trading Group Size For Degree Of Altruism, Leticia Avilés, Jeffrey Alan Fletcher, Asher D. Cutter

Complex Systems Faculty Publications and Presentations

Why some social systems form groups composed of kin, while others do not, has gone largely untreated in the literature. Using an individual-based simulation model, we explore the demographic consequences of making kinship a criterion in group formation. We find that systems where social groups consist of one generation breeding associations may face a serious trade-off between degree of altruism and group size that is largely mediated by their kin composition. On the one hand, restricting groups to close kin allows the evolution of highly altruistic behaviors but may limit group size to suboptimal levels, the more severely so the …

Long-Term Evaluation Of The Use Of The Transdermal Contraceptive Patch In Adolescents, Stephanie Logsdon, Jessica Richards, Hatim A. Omar

Pediatrics Faculty Publications

The transdermal contraceptive patch, Ortho Evra™, was approved in December 2001 and released on the market in June 2002. In this study, we reviewed clinical data of young women who started the patch between June 2002 and December 2003 in the adolescent medicine clinic at a university-based outpatient center. A total of 62 patients started the patch in that period and two of them were lost to follow-up. Mean age of patients was 17.9 years and mean length of use was 10 cycles. Only 10 patients (16.7%) discontinued use. Reasons for discontinuation were moderate to severe skin irritation (3 patients, …

Clinical Profiles, Occurrence, And Management Of Adolescent Patients With Hair-An Syndrome, Hatim A. Omar, Stephanie Logsdon, Jessica Richards

Pediatrics Faculty Publications

The syndrome of hyperandrogenism, insulin resistance, and acanthosis nigricans (HAIR-AN) is a subphenotype of the polycystic ovary syndrome. It is one of the most common causes of menstrual problems, hyperandrogenic symptoms, and insulin resistance among young women. Review of clinical data in an outpatient adolescent clinic showed that of the 1,002 young women (ages 10-21 years) attending the clinic over a 2-year period, 50 (5%) were diagnosed with HAIR-AN syndrome. Mean age of the patients was 15.5, initial mean weight at diagnosis was 94.5 kg, and the mean BMI was 33.33 kg/m2. Patients were treated with a weight-stabilization and -reduction …

The Effect Of Religiosity And Spirituality On Work Practices And Trust Levels In Managers And Their Subordinates In Food And Nutrition Care Departments, Jennifer S. Oler

Theses and Dissertations

The purpose of this study was to examine the extent to which religiosity and spirituality affected daily work practices and leader/follower trust levels in foodservice and nutrition directors and their subordinates. A similar 72-item survey questionnaire was developed for both the directors and employees, which was completed by 129 directors and 530 employees. Both questionnaires contained questions on demographics, religious influences on work practices, trust characteristics, and three validated measures of religiosity: 1) worship service attendance (1=Religiosity Score), 2) influence of spiritual beliefs on daily life, and 3) frequency of prayer (2 + 3=Spirituality Score). Frequency data was gathered for …
