Mos2 Doped Tio2 Nanomaterial And The Enhancement Of Photocatalytic Properties For Solar Disinfection, Timothy Mccolgan
USF St. Petersburg campus Master's Theses (Graduate)
This research project focused on the synthesis, characterization, and environmental application of a photocatalytic nanomaterial composed of molybdenum (IV) disulfide [MOS2] doped titanium dioxide [TiO2]. Extensive research has been conducted on the electronic uses of nanocrystalline MoS2 as a phototransistor and absorptive species (Yin et al., 2012), as well as the photocatalytic effects of TiO2 (Diebold, 2003). Research has also been performed into the generation of oxidizers from TiO2 nanocomposites (Zhang et al., 2015), but as of yet no research has been conducted on a practical application of this material. This project fills that void by evaluating its effectiveness while …
Spatial And Temporal Levels Of Microplastics In Tampa Bay Surface Waters, Laurinda Kinsley Mceachern
Spatial And Temporal Levels Of Microplastics In Tampa Bay Surface Waters, Laurinda Kinsley Mceachern
USF St. Petersburg campus Master's Theses (Graduate)
This study focused on collecting microplastics in Tampa Bay estuarine surface waters in order to identify temporal and spatial differences. While there have been many studies of microplastic contamination in the marine environment over the past decade, quantifying microplastics in urban estuaries is constrained. This study provides an understanding of the abundance, distribution, and composition of microplastics at twenty sites in Tampa Bay as well as four ancillary tributary stations. The objectives of the study were to identify how surrounding land use type, freshwater sources, seasonal changes in precipitation, and wastewater treatment plant discharge affect microplastic concentrations. Water samples were …
Determining Potential Uptake Pathways Of Persistent Organic Pollutants And Heavy Metals In Jobos Bay National Estuarine Research Reserve, Puerto Rico, Ashley Huber
USF St. Petersburg campus Master's Theses (Graduate)
Fiddler Crab (U. rapax) tissue, mangrove tissue and sediment from crab burrows were collected in Jobos Bay National Estuarine Research Reserve, Puerto Rico, to quantitate Persistent Organic Pollutants (OCs, PCBs, PBDEs) and selected heavy metals (cadmium, barium, mercury, lead, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic and selenium). Once quantified, the concentrations were applied to a bioconcentration factor equation to determine potential uptake pathways of the target analytes. Bioconcentration factors determined that fiddler crabs were the most efficient at concentrating OC pesticides, while mangroves were the most efficient at concentrating PCBs and heavy metals.

Soil Accumulation, Accretion, And Organic Carbon Burial Rates In Mangrove Soils Of The Lower Florida Keys: A Temporal And Spatial Analysis, Amanda R. Chappel
USF St. Petersburg campus Master's Theses (Graduate)
This study compared the temporal variability in rates of soil accumulation, accretion, and organic carbon (OC) burial from three sites in the Lower Florida Keys using two different radiometric dating techniques (210Pb, 14C). Comparison of these rates across various timescales (decadal, centurial, and millennial) permitted examination of temporal responses and drivers. Further, spatial variability was measured for these associated site rates. Differences in geographic location and site morphologies as predicted, were supported by spatial variability in all rates across sites with the exception of centurial rates of accretion. All rates were greater when assessed over shorter (e.g. decadal) timescales. The …

Insights Into Key Gene Regulatory Networks In Borrelia Burgdorferi, William Kenneth Arnold
Insights Into Key Gene Regulatory Networks In Borrelia Burgdorferi, William Kenneth Arnold
Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics
Gene regulatory networks are composed of interconnected regulatory nodes created by regulatory factors of multiple types. All organisms finely tune gene expression in order to adapt to and survive within their current niche. Obligate parasitic bacteria are under extreme pressure to quickly and appropriately adapt their gene regulatory programs in order to survive within their given host. Borrelia burgdorferi is one such organism and persists in nature by alternating between two hosts; Ixodes spp. ticks and small vertebrate animals. These two hosts represent drastically different environments; requiring a unique gene regulatory program to survive and transmit between them. Microbiologists have …
The Imprint Of Childhood Abuse On Trauma-Related Shame In Adulthood., Joan Reid
The Imprint Of Childhood Abuse On Trauma-Related Shame In Adulthood., Joan Reid
USF St. Petersburg Campus Faculty Publications
Research has consistently linked residual trauma-related shame among child sexual abuse (CSA) survivors to sexual revictimization, health risk behaviors, and poorer response to mental health treatment. However, questions remain regarding the imprint of childhood maltreatment on trauma-related shame including which CSA characteristics or types of childhood maltreatment contribute to residual shame in adulthood. Using data drawn from a prospective study of 174 primarily African American women with histories of CSA and a matched comparison group, this study explores whether specific characteristics of CSA (familial CSA, CSA with penetration, force used by CSA perpetrator), repeat sexual victimization in adolescence, childhood physical …

Mounting evidence has indicated that early intervention leads to improved clinical and functional outcomes for young persons experiencing recent onset psychosis. As part of a large early detection campaign, the present study aimed to investigate subjective experiences during the duration of untreated psychosis (DUP), or time between psychosis onset and treatment contact. Participants were 10 young adults participating in early intervention services for psychosis. After DUP was estimated during standardized baseline assessment, participants engaged in qualitative interviews focused on their life experiences prior to treatment and leading up to the present. Mixed methods data analyses compared standardized DUP estimates with …

Unprecedented Diversity Of Ssdna Phages From The Family Microviridae Detected Within The Gut Of A Protochordate Model Organism (Ciona Robusta), Alexandria Creasy, Karyna Rosario, Brittany Leigh, Larry Dishaw, Mya Breitbart
Marine Science Faculty Publications
Phages (viruses that infect bacteria) play important roles in the gut ecosystem through infection of bacterial hosts, yet the gut virome remains poorly characterized. Mammalian gut viromes are dominated by double-stranded DNA (dsDNA) phages belonging to the order Caudovirales and single-stranded DNA (ssDNA) phages belonging to the family Microviridae. Since the relative proportion of each of these phage groups appears to correlate with age and health status in humans, it is critical to understand both ssDNA and dsDNA phages in the gut. Building upon prior research describing dsDNA viruses in the gut of Ciona robusta, a marine invertebrate model system …

Zooplankton dominate the abundance and biomass of multicellular animals in pelagic marine environments; however, traditional methods to characterize zooplankton communities are invasive and laborious. This study compares zooplankton taxonomic composition revealed through metabarcoding of the cytochrome oxidase I (COI) and 18S rRNA genes to traditional morphological identification by microscopy. Triplicates of three different sample types were collected from three coral reef sites in the Florida Keys National Marine Sanctuary: (1) 1 L surface seawater samples prefiltered through 3 μm filters and subsequently collected on 0.22 μm filters for eDNA (PF‐eDNA); (2) 1 L surface seawater samples filtered on …

Linking Capacity Development To Goos Monitoring Networks To Achieve Sustained Ocean Observation, Frank E. Muller-Karger
Marine Science Faculty Publications
Developing enduring capacity to monitor ocean life requires investing in people and their institutions to build infrastructure, ownership, and long-term support networks. International initiatives can enhance access to scientific data, tools and methodologies, and develop local expertise to use them, but without ongoing engagement may fail to have lasting benefit. Linking capacity development and technology transfer to sustained ocean monitoring is a win-win proposition. Trained local experts will benefit from joining global communities of experts who are building the comprehensive Global Ocean Observing System (GOOS). This two-way exchange will benefit scientists and policy makers in developing and developed countries. The …

Seasonal Patterns In Phytoplankton Biomass Across The Northern And Deep Gulf Of Mexico: A Numerical Model Study, Fabian A. Gomez, Sang-Ki Lee, Frank J. Hernandez Jr, Frank E. Muller-Karger, John T. Lamkin
Marine Science Faculty Publications
Biogeochemical models that simulate realistic lower-trophic-level dynamics, including the representation of main phytoplankton and zooplankton functional groups, are valuable tools for improving our understanding of natural and anthropogenic disturbances in marine ecosystems. Previous three-dimensional biogeochemical modeling studies in the northern and deep Gulf of Mexico (GoM) have used only one phytoplankton and one zooplankton type. To advance our modeling capability of the GoM ecosystem and to investigate the dominant spatial and seasonal patterns of phytoplankton biomass, we configured a 13-component biogeochemical model that explicitly represents nanophytoplankton, diatoms, micro-, and mesozooplankton. Our model outputs compare reasonably well with observed patterns in …

Impacts Of 40 Years Of Land Cover Change On Water Quality In Tampa Bay, Florida, Matthew J. Mccarthy, Frank E. Muller-Karger, Daniel Otis, Pablo Méndez-Lázaro
Marine Science Faculty Publications
Land cover changes in the Tampa Bay watershed (Florida) over the past four decades were examined along with precipitation and wind observations to help understand causes of long-term changes in turbidity and chlorophyll concentration within the Tampa Bay estuary. Water quality showed a statistically significant relationship to land cover fraction in the watershed compared to long-term precipitation or wind stress. Redundancy Analyses with Akaike’s Information Criterion and non-parametric multiple regressions determined that turbidity and chlorophyll concentration decreased bay-wide from 1974–2012 with increased developed land fraction (R2 > 0.75, p-value < 0.05). Various segments of the estuary showed different significant responses to developed land (R2 > 0.75, p-value < 0.05), agricultural land (R2 > 0.93, p-value < 0.02), bare land (R2 = 0.77, p-value = 0.001), and wind stress (R2 = 0.91, p-value = 0.04) at different times of year.

The expression of the Clostridium difficile binary toxin CDT is generally observed in the RT027 (ST1) and RT078 (ST11) C. difficile isolates, which are associated with severe C. difficile infection (CDI). However, we recently reported that the non-RT027 and non-RT078 C. difficile strain LC693 (TcdA+TcdB+ CDT+, ST201) caused severe diarrhea in a patient in Xiangya Hospital in China. C.difficile LC693 is a member of Clade 3, and in this study, we identified LC693 as RT871 and compared its virulence and pathogenicity to those of C.difficile R20291 (TcdA+TcdB+CDT+, ST1/RT027), UK6 (TcdA+TcdB+CDT+, ST35/RT027), CD630 (TcdA+TcdB+CDT−, ST54, RT012), and 1379 (TcdA+TcdB+CDT−, ST54/RT012), with …

Inhibition of fibrillation process and disaggregation of mature fibrils using small peptide are the promising remedial strategies to combat neurodegenerative diseases. However, designing peptide-based drugs to target β-sheet-rich amyloid has been a major challenge. The current work describes, for the first time, the amyloid inhibitory potential of the two short peptides (selected on the basis of predisposition of their amino acid residues toward β-sheet formation) using combination of biophysical, imaging methods, and docking approaches. Results showed that peptides employed different mechanisms to inhibit the amyloid fibrillation. Furthermore, they were also effective in blocking the amyloid fibrillation pathway. In contrary to …

Molecular Medicine Faculty Publications
Biosynthesis of heme represents a complex process that involves multiple stages controlled by different enzymes. The first of these proteins is a pyridoxal 5′-phosphate (PLP)-dependent homodimeric enzyme, 5-aminolevulinate synthase (ALAS), that catalyzes the rate-limiting step in heme biosynthesis, the condensation of glycine with succinyl-CoA. Genetic mutations in human erythroid-specific ALAS (ALAS2) are associated with two inherited blood disorders, X-linked sideroblastic anemia (XLSA) and X-linked protoporphyria (XLPP). XLSA is caused by diminished ALAS2 activity leading to decreased ALA and heme syntheses and ultimately ineffective erythropoiesis, whereas XLPP results from “gain-of-function” ALAS2 mutations and consequent overproduction of protoporphyrin IX and increase in …

Intrinsically Disordered Proteins And The Janus Challenge, Prakash Kulkarni, Vladimir N. Uversky
Molecular Medicine Faculty Publications
To gain a new insight into the role of proteins in the origin of life on Earth, we present the Janus Challenge: identify an intrinsically disordered protein (IDP), naturally occurring or synthetic, that has catalytic activity. For example, such a catalytic IDP may perform condensation reactions to catalyze a peptide bond or a phosphodiester bond formation utilizing natural/un-natural amino acids or nucleotides, respectively. The IDP may also have autocatalytic, de novo synthesis, or self-replicative activity. Meeting this challenge may not only shed new light and provide an alternative to the RNA world hypothesis, but it may also serve as an …
