A Novel Approach To X-Ray Mirror Bending Stability And Control, Michael Weinbaum

USF Tampa Graduate Theses and Dissertations

A novel, no-contact approach to X-ray mirror bending control is presented here,

proposed for use on the beamlines of the European X-ray Free Electron Laser (XFEL)

project. A set of mirrors with tunable bending radii are desired, that will maintain their

optical properties even as the beam incidence causes local heating. Various mechanical

bending mechanisms have been proposed and used on other beamlines, which can take up

a lot of physical space, demanding more vacuum power, while using expensive high

precision servomotors. Rather than bend the mirror by mechanical means, it is proposed

to heat the mirror to produce the …

Engines Of The Ocean: Diatoms And Their Genetic Readout Under Nutrient Limitation, Bethany Jenkins

Amgen Seminar Series in Chemical Engineering

Diatoms are important photosynthetic organisms in lakes and oceans; they take up CO2 and fix it into carbon building blocks for the cell. Therefore, they help balance atmospheric inputs of CO2. Diatoms also bioprecipitate silica and form nano-patterned cell walls that are unique between species. Diatom genomes have been sequenced to gain a better understanding of the architectural underpinnings for these processes. Diatoms live in environments with fluctuating nutrients, which can constrain photosynthesis and growth. My laboratory is conducting experiments to understand how diatoms respond to nutrient limitation and we are using methods to profile and quantify the expression of …

Fish Communities On The World's Warmest Reefs: What Can They Tell Us About The Effects Of Climate Change In The Future?, David A. Feary, John A. Burt, Andrew G. Bauman, Paolo Usseglio, Peter F. Sale, Georgenes Cavalcante

Marine & Environmental Sciences Faculty Articles

To examine the role of climatic extremes in structuring reef fish communities in the Arabian region, reef fish communities were visually surveyed at four sites within the southern Persian Gulf (also known as the Arabian Gulf and The Gulf), where sea-surface temperatures are extreme (range: 12–35° C annually), and these were compared with communities at four latitudinally similar sites in the biogeographically connected Gulf of Oman, where conditions are more moderate (range: 22–31° C annually). Although sites were relatively similar in the cover and composition of coral communities, substantial differences in the structure and composition of associated fish assemblages were …

Plant Phenolics: Extraction, Analysis And Their Antioxidant And Anticancer Properties, Jin Dai, Russell J. Mumper

Pharmaceutical Sciences Faculty Publications

Phenolics are broadly distributed in the plant kingdom and are the most abundant secondary metabolites of plants. Plant polyphenols have drawn increasing attention due to their potent antioxidant properties and their marked effects in the prevention of various oxidative stress associated diseases such as cancer. In the last few years, the identification and development of phenolic compounds or extracts from different plants has become a major area of health- and medical-related research. This review provides an updated and comprehensive overview on phenolic extraction, purification, analysis and quantification as well as their antioxidant properties. Furthermore, the anticancer effects of phenolics in-vitro …

Characterization Of Subsurface Polycyclic Aromatic Hydrocarbons At The Deepwater Horizon Site, Arne Diercks, Raymond C. Highsmith, Vernon L. Asper, Dongjoo Joung, Zhengzhen Zhou, Laodong Guo, Alan M. Shiller, Andreas P. Teske, Norman Guinasso, Terry L. Wade, Steven E. Lohrenz

Faculty Publications

Here, we report the initial observations of distributions of polycyclic aromatic hydrocarbons (PAH) in subsurface waters near the Deepwater Horizon oil well site (also referred to as the Macondo, Mississippi Canyon Block 252 or MC252 well). Profiles of in situ fluorescence and beam attenuation conducted during 9-16 May 2010 were characterized by distinct peaks at depths greater than 1000 m, with highest intensities close to the wellhead and decreasing intensities with increasing distance from the wellhead. Gas chromatography/mass spectrometry (GC/MS) analyses of water samples coinciding with the deep fluorescence and beam attenuation anomalies confirmed the presence of polycyclic aromatic hydrocarbons …

The Combined Effect Of Environmental And Host Factors On The Emergence Of Viral Rna Recombinants, Hannah M. Jaag, Peter D. Nagy

Plant Pathology Faculty Publications

Viruses are masters of evolution due to high frequency mutations and genetic recombination. In spite of the significance of viral RNA recombination that promotes the emergence of drug-resistant virus strains, the role of host and environmental factors in RNA recombination is poorly understood. Here we report that the host Met22p/Hal2p bisphosphate-3'-nucleotidase regulates the frequency of viral RNA recombination and the efficiency of viral replication. Based on Tomato bushy stunt virus (TBSV) and yeast as a model host, we demonstrate that deletion of MET22 in yeast or knockdown of AHL, SAL1 and FRY1 nucleotidases/phosphatases in plants leads to increased TBSV recombination …

Determination Of Structure Of Hepatitis B Virus E Antigen, Asheel Patel

Theses and Dissertations

Hepatitis B virus is a member of the hepadnavirus family. The hepatitis B virus core gene codes for two proteins viz. core protein and pre-core protein. These proteins assemble to form particles viz. HBcAg and HBeAg respectively. The structure of the HBcAg has been widely studied but very little is known about the structure of HBeAg. Therefore, the aim of this study was to identify the disulfide bonding patterns in HBeAg. Recombinant HBeAg was isolated from E.coli and used for this study along with various mutants of HBeAg. There are four cysteines present in HBeAg each at position -7, 48, …

Inherent High Correlation Of Individual Motility Enhances Population Dispersal In A Heterotrophic, Planktonic Protist, Susanne Menden-Deuer

Graduate School of Oceanography Faculty Publications

Quantitative linkages between individual organism movements and the resulting population distributions are fundamental to understanding a wide range of ecological processes, including rates of reproduction, consumption, and mortality, as well as the spread of diseases and invasions. Typically, quantitative data are collected on either movement behaviors or population distributions, rarely both. This study combines empirical observations and model simulations to gain a mechanistic understanding and predictive ability of the linkages between both individual movement behaviors and population distributions of a single-celled planktonic herbivore. In the laboratory, microscopic 3D movements and macroscopic population distributions were simultaneously quantified in a 1L tank, …

Investigating The Mode Of Action Of A Novel N-Sec-Butylthiolated Beta-Lactam Against Staphylococcus Aureus, Katherine Rose Prosen

USF Tampa Graduate Theses and Dissertations

N-sec

-butylthioloated β-lactam (NsβL) is a novel beta-lactam antimicrobial with a mechanism of action proposed to inhibit 3-oxoacyl-acyl carrier protein synthase (ACP) III (FabH), resulting in the inhibition of fatty acid synthesis. It has been suggested that NsβL inhibits FabH indirectly by inactivating coenzyme-A (CoA). CoA is an essential cofactor for numerous proteins involved in glycolysis, the citric acid cycle (TCA), and pyruvate metabolism, in addition to fatty acid biosynthesis. This study aimed to determine the effects of NsβL on a diverse array of laboratory and clinical Staphylococcus aureus isolates by analyzing the mode of resistance in spontaneous and adaptive …

Alkylation Of The Tumor Suppressor Pten Activates Akt And Β-Catenin Signaling: A Mechanism Linking Inflammation And Oxidative Stress With Cancer, Tracy M. Covey, Kornelia Edes, Gary S. Coombs, David M. Virshup, Frank A. Fitzpatrick

Faculty and Staff Publications

PTEN, a phosphoinositide-3-phosphatase, serves dual roles as a tumor suppressor and regulator of cellular anabolic/catabolic metabolism. Adaptation of a redox-sensitive cysteinyl thiol in PTEN for signal transduction by hydrogen peroxide may have superimposed a vulnerability to other mediators of oxidative stress and inflammation, especially reactive carbonyl species, which are commonly occurring by-products of arachidonic acid peroxidation. Using MCF7 and HEK-293 cells, we report that several reactive aldehydes and ketones, e.g. electrophilic α,β-enals (acrolein, 4-hydroxy-2-nonenal) and α,β-enones (prostaglandin A(2), Δ12-prostaglandin J(2) and 15-deoxy-Δ-12,14-prostaglandin J(2)) covalently modify and inactivate cellular PTEN, with ensuing activation of PKB/Akt kinase; phosphorylation of Akt substrates; increased …

Expertise3: Outcomes Of Instructor Collaboration On Elementary Teacher Education In Mathematics, Mary P. Truxaw, Fabiana Cardetti, Cynthia A. Bushey

NERA Conference Proceedings 2010

This research grew from two university faculty members’ and one doctoral student’s collaboration across different academic fields (mathematics and education) to better serve elementary preservice teachers (PSTs). The collaboration resulted in shared expertise and an ongoing investigation of confidence of mathematical content knowledge (M-CK) and mathematics pedagogical content knowledge (M-PCK) of PSTs who participated in math content coursework designed for elementary teachers. Findings suggest that PSTs who take one or more of these content courses, along with a mathematics methods course, have higher M-CK and M-PCK than PSTs who take only traditional mathematics courses along with a mathematics methods course.
