Investigations Of The Physical And Analytical Chemistry Of Iron In Aqueous Solutions, James Patten

USF Tampa Graduate Theses and Dissertations

Although iron occurs at extremely low concentrations in the world’s oceans, it is essential for all living organisms. It is the limiting nutrient in High Nutrient Low Chlorophyll (HNLC) areas of the ocean, and exerts critically important influences on levels of atmospheric CO₂ and the global carbon cycle. Understanding the chemical processes that govern the fluxes and biogeochemistry of oceanic iron requires thorough assessment of the aqueous physical chemistry of iron and analytical techniques capable of measuring iron at sub-nanomolar concentration measurements. This dissertation extends prior work on the physical and analytical chemistry of iron through (a) investigation of …

A Plausible Mechanism, Based Upon Short-Root Movement, For Regulating The Number Of Cortex Cell Layers In Roots., Shuang Wu, Chin-Mei Lee, Tomomi Hayashi, Simara Price, Fanchon Divol, Sophia Henry, Germain Pauluzzi, Christophe Perin, Kimberly L Gallagher

Department of Medical Laboratory Sciences & Biotechnology Faculty Papers

Formation of specialized cells and tissues at defined times and in specific positions is essential for the development of multicellular organisms. Often this developmental precision is achieved through intercellular signaling networks, which establish patterns of differential gene expression and ultimately the specification of distinct cell fates. Here we address the question of how the SHORT-ROOT (SHR) proteins from Arabidopsis thaliana (AtSHR), Brachypodium distachyon (BdSHR), and Oryza sativa (OsSHR1 and OsSHR2) function in patterning the root ground tissue. We find that all of the SHR proteins function as mobile signals in A. thaliana and all of the SHR homologs physically interact …

Identification Of Small Molecule Compounds That Regulate Pdgfra Transcription In Oligodendrocyte Progenitor Cells, Jelena Medved

Doctoral Dissertations

Oligodendrocyte progenitor cells (OPCs) are precursor cells that give rise to oligodendrocytes, cells that form myelin, an arrangement of membrane sheaths enwrapping axons, necessary for fast transmission of electrical impulses in the nervous system. OPCs generate oligodendrocytes during development, adulthood and in pathological conditions.

Generation of oligodendrocytes from OPCs is in part regulated by growth factors. The major survival factor and mitogen for OPCs is platelet derived growth factor (PDGF). PDGF and its receptor, PDGF receptor A (PDGFRA), are critical regulators of OPC proliferation and their differentiation. PDGFRA gain-of-function can lead to excessive proliferation and is associated with a number …

Pediatrics Faculty Publications

Background

The potential benefits of corticosteroids for septic shock may depend on initial mortality risk.

Objective

We determined associations between corticosteroids and outcomes in children with septic shock who were stratified by initial mortality risk.

Methods

We conducted a retrospective analysis of an ongoing, multi-center pediatric septic shock clinical and biological database. Using a validated biomarker-based stratification tool (PERSEVERE), 496 subjects were stratified into three initial mortality risk strata (low, intermediate, and high). Subjects receiving corticosteroids during the initial 7 days of admission (n = 252) were compared to subjects who did not receive corticosteroids (n = 244). Logistic regression …

Method And Composition For Modulating Canonical Wnt Pathway Using Folate And Inositol, Kersti K. Linask

USF Patents

The canonical Wnt signaling pathway is implicated in many disorders including neural tube defects, limb malformations, and heart defects, developmental disorders associated with alcohol exposure (fetal alcohol syndrome) or exposure to bipolar medications (i.e. lithium), wound healing, and Alzheimer's disease. Elevated plasma homocysteine (HCy), which results from folate (folic acid, FA) deficiency, the mood-stabilizing drug lithium (Li), and alcohol (ethanol) are linked to the induction of human congenital heart and neural tube defects. FA supplementation ameliorates the observed developmental errors in the Li-HCy, or alcohol-exposed mouse embryos and normalized heart function. Li, HCy or Wnt3A suppress Wnt-modulated Hex and Islet-1 …

Department of Chemistry Publications

Infection-related complications have been a critical issue for the application of titanium orthopedic implants. The use of Ag nanoparticles offers a potential approach to incorporate antimicrobial properties into the titanium implants. In this work, a novel and simple method was developed for synthesis of Ag (II) oxide deposited TiO₂ nanotubes (TiNTs) using electrochemical anodization followed by Ag electroplating processes in the same electrolyte. The quantities of AgO nanoparticles deposited in TiNT were controlled by selecting different electroplating times and voltages. It was shown that AgO nanoparticles were crystalline and distributed throughout the length of the nanotubes. Inductively coupled plasma …

Ploidy Number For Panicum Virgatum (Switchgrass) From The Long Island Sound Coastal Lowland Compared To Upland And Lowland Cultivars., Tanisha Williams, Carol Auer

Plant Science Articles

Panicum virgatum L. (switchgrass) is a native, perennial grass in North America with important ecological function in ecoregions including the Long Island Sound Coastal Lowland in the Northeastern United States. In recent decades, switchgrass has become a model lignocellulosic bioenergy crop with a large research portfolio describing its distribution, genetics, genomics, phenology, traits, gene flow, and cultivation. Switchgrass has been divided into two ecotypes, the Lowland ecotype which is tetraploid (2n= 4x= 36 chromosomes) and the Upland ecotype which is tetraploid or octaploid (2n= 8x= 72). While most switchgrass research has focused on genotypes from the Midwest or Southeastern regions, …

Suppression Of Subtelomeric Vsg Switching By Trypanosoma Brucei Trf Requires Its Ttaggg Repeat-Binding Activity, Sanaa E. Jehi, Xiaohua Li, Ranjodh Sandhu, Fei Ye, Imaan Benmerzouga, Mingjie Zhang, Yanxiang Zhao, Bibo Li

Biological, Geological, and Environmental Faculty Publications

Trypanosoma brucei causes human African trypanosomiasis and regularly switches its major surface antigen, VSG, in the bloodstream of its mammalian host to evade the host immune response. VSGs are expressed exclusively from subtelomeric loci, and we have previously shown that telomere proteins TbTIF2 and TbRAP1 play important roles in VSG switching and VSG silencing regulation, respectively. We now discover that the telomere duplex DNA-binding factor, TbTRF, also plays a critical role in VSG switching regulation, as a transient depletion of TbTRF leads to significantly more VSG switching events. We solved the NMR structure of the DNA-binding Myb domain of TbTRF, …

Gender Diversity And Same-Sex Marriage, Ian Farrell, Nancy Leong

Sturm College of Law: Faculty Scholarship

Opponents of same-sex marriage have recently adopted a curious new argument. The argument goes something like this. The Supreme Court has held that diversity is a compelling state interest in institutions of higher education. Opposite-sex marriage includes gender diversity, while same-sex marriage does not. Therefore, states may allow same-sex marriage while banning opposite-sex marriage — even if the ban triggers heightened scrutiny under equal protection or due process — because opposite-sex marriage furthers gender diversity, while same-sex marriage does not.

The gender diversity argument against same-sex marriage has made its way into a number of briefs during the recent increase …
