Evaluation Of Aluminum Dissolution, Current Density, And Pitting Patterns During Electrocoagulation, Monica Castro Carias

USF Tampa Graduate Theses and Dissertations

Electrocoagulation (EC) is a sustainable water treatment process involving the generation of coagulants on-site through the application of a voltage on metal (usually aluminum or iron alloys). The factors that impact EC system performance have been well researched, however further research is needed on the factors that impact anodic dissolution of aluminum electrodes, especially when the technology is transferred to full-scale applications. Electrode fouling is one of the factors that can impact dissolution of the anode during EC due to the formation of a protective oxide/hydroxide layer on the electrode surface. Previous studies have addressed electrode fouling by reversing polarity, …

Inhibitory Control Of Emotional Interference In Deaf Children: Evidence From Event-Related Potentials And Event-Related Spectral Perturbation Analysis, Qiong Chen, Junfeng Zhao, Huang Gu, Xiaoming Li Ph.D.

Faculty Publications

Background: Impairment of interference control ability may reflect a more general deficit in executive functioning, and lead to an increase in internal-externalized problems such as impulsivity, which has been reported in deaf children. However, few researches have examined the neural mechanism of this impairment.

Methods: This study applied the electroencephalogram (EEG) technique to investigate the interference control ability in 31 deaf children and 28 hearing controls with emotional face-word stroop task.

Results: Results from behavioral task showed that deaf children exhibited lower accuracy compared to hearing controls. As for EEG analysis, reduced activation of ERP components in N1 and enhanced …

Crispr/Cas13 Effectors Have Differing Extents Of Off-Target Effects That Limit Their Utility In Eukaryotic Cells

Faculty, Staff and Students Publications

CRISPR/Cas13 effectors have garnered increasing attention as easily customizable tools for detecting and depleting RNAs of interest. Near perfect complementarity between a target RNA and the Cas13-associated guide RNA is required for activation of Cas13 ribonuclease activity. Nonetheless, the specificity of Cas13 effectors in eukaryotic cells has been debated as the Cas13 nuclease domains can be exposed on the enzyme surface, providing the potential for promiscuous cleavage of nearby RNAs (so-called collateral damage). Here, using co-transfection assays in Drosophila and human cells, we found that the off-target effects of RxCas13d, a commonly used Cas13 effector, can be as strong as …

Positive Rate-Dependent Action Potential Prolongation By Modulating Potassium Ion Channels, Candido Cabo

Publications and Research

Pharmacological agents that prolong action potential duration (APD) to a larger extent at slow rates than at the fast excitation rates typical of ventricular tachycardia exhibit reverse rate dependence. Reverse rate dependence has been linked to the lack of efficacy of class III agents at preventing arrhythmias because the doses required to have an anti-arrhythmic effect at fast rates may have pro-arrhythmic effects at slow rates due to an excessive APD prolongation. In this report we show that, in computer models of the ventricular action potential, APD prolongation by accelerating phase 2 repolarization (by increasing I_Ks) and decelerating …

Engineering The Lanthanide And Actinide Dopants Effects On The Local Environment Of Luminescent Complex Metal Oxide, Yuming Wang

LSU Doctoral Dissertations

Rare earth (RE) based phosphor materials are widely used as luminescent probes in high-temperature optical thermometry where standard methods are unsuitable. The current generation of luminescent thermometers lacks stability and energy transport within the operating temperature ranges. The challenge is developing an oxide-based material with high luminescence intensity and thermal sensitivity/stability, suitable for an optical temperature sensor/thermal barrier coating. This work aims to develop a fundamental understanding of the local environment surrounding RE or actinide dopants in metal oxide hosts to engineer their luminescence property. To maximize the luminescence, the local symmetry, doping concentration, and radiative/non-radiative relaxation pathways must be …

Faculty, Staff and Students Publications

BACKGROUND: Children with inflammatory bowel disease [IBD] are disproportionally affected by recurrent Clostridioides difficile infection [rCDI]. Although faecal microbiota transplantation [FMT] has been used with good efficacy in adults with IBD, little is known about outcomes associated with FMT in paediatric IBD.

METHODS: We performed a retrospective review of FMT at 20 paediatric centres in the USA from March 2012 to March 2020. Children with and without IBD were compared with determined differences in the efficacy of FMT for rCDI. In addition, children with IBD with and without a successful outcome were compared with determined predictors of success. Safety data …

Osteosarcoma Occurrence In Preclinical And Clinical Experiments With Teriparatide: A Qualitative Review, Wlla Wail Al-Halbouni, Moawia M. Al-Tabakha, Akram A. Ashames, Adi I. Arida, Muaed J. Alomar

The Thai Journal of Pharmaceutical Sciences

Teriparatide (TPTD) is one of the medications commonly prescribed for the treatment of osteoporosis since its approval in November 2002 by the U.S. Food and Drug Administration (FDA). While some preclinical toxicological studies have linked the drug to a dose-dependent increase in the occurrence of osteosarcoma, clinical trials showed the benefits outweighing the risk for TPTD-induced human osteosarcoma. The objective of this qualitative review was to qualitatively assess the literature for the association of osteosarcoma and the usage of TPTD in animal and human subjects. Studies were selected from all available records in the electronic databases covering the period from …

Developing A Scale To Measure Destination Gender, Tingting Zhang

Rosen Research Review

Whether they depict the rugged landscape of the American West or the seductive charm of a South Asian beach, photographs and their accompanying text are powerful drivers of tourism demand. But what lies behind our response to such tourism tropes? Rosen College researchers have produced a new study which reappraises destination marketing through a gender-based lens. Led by Dr. Tingting Zhang, the study has developed and validated a cross-cultural scale to determine ‘destination gender’, or whether a location should be thought of as having masculine or feminine gender traits and appeal.

Effects Of Forest Restoration On The Recovery Of Dead Wood, Associated Arthropods, And Insect-Mediated Wood Decomposition, Estefania Fernandez Barrancos

Dissertations

Dead wood represents 8% of terrestrial carbon stocks and is an important source of habitat and food for decomposer and non-decomposer arthropods. However, anthropogenic disturbance reduces the amount of dead wood, putting at risk the presence of a habitat that is essential for many arthropods and other organisms that rely on it for food and shelter. Forest restoration aims to assist the recovery of ecosystems that have been damaged or destroyed and could be a means to recover both dead wood and its associated arthropod communities. This doctoral dissertation lies at the intersection of climate change, biodiversity loss and ecological …

Effect Of Ischemia-Reperfusion Injury And Preconditioning On Lung Parenchyma After Acute Limb Ischemia, David Hutagaol, Dhama S. Susanti, Wuryantoro Soeharto, Muhammad A. Putra, Suprayitno Wardoyo, William Makdinata, Moira Setiawan

The New Ropanasuri Journal of Surgery

Introduction. Acute limb ischemia, a sudden decrease of perfusion to the extremities, can compromise the survival of the limbs. Medical intervention and surgery are often needed to return perfusion. However, reperfusion injury can trigger oxidative stress and inflammatory response, leading to local and remote tissue damage, such as the lungs, which increases morbidity and mortality. This research aims to study the effects of hypothermia and remote ischemic preconditioning (RIPC) on the lung parenchyma after being exposed to reperfusion after acute limb ischemia in rabbits.

Method. Eighteen New Zealand White rabbits were divided into three groups of 6. The …

Nitrogen Fixation Rates In Forested Mountain Streams: Are Sediment Microbes More Important Than Previously Thought?, Erica A. H. Bakker, Carmella Vizza, Clay Arango, Sarah S. Roley

Biology Faculty Scholarship

1. Biological nitrogen (N) fixation, the microbial conversion of N₂ gas to ammonia, makes N available to food webs. Low-N streams often have a high relative abundance of N-fixing taxa, suggesting that N fixation is an important N source in these systems. Despite this potential, stream N fixation has not been well-characterised, particularly compared to lakes and marine environments. One unknown is the relative contributions of various N-fixing organisms, particularly heterotrophic microbes.
2. In low-N streams in the Cascade Mountains (Washington, USA), three groups of N-fixers predominate: cyanobacteria (Nostoc paramelioides) colonies that house a midge symbiont (Cricotopus spp.), …

Peripherally Restricted Transthyretin-Based Delivery System For Probes And Therapeutics Avoiding Opioid-Related Side Effects, Md Tariqul Haque Tuhin, Dengpan Liang, Fang Liu, Hala Aldawod, Toufiq Ul Amin, Joshua S. Ho, Rasha Emara, Arjun D. Patel, Melanie A. Felmlee, Miki S. Park, James A. Uchizono, Mamoun M. Alhamadsheh

School of Pharmacy Faculty Articles

Several investigations into the sites of action of opioid analgesics have utilized peripherally acting mu-opioid receptor antagonists (PAMORAs), which have been incorrectly assumed to possess limited permeability across the blood-brain barrier. Unfortunately, the poor pharmacokinetic properties of current PAMORAs have resulted in misunderstandings of the role of central nervous system and gastrointestinal tract in precipitating side effects such as opioid-induced constipation. Here, we develop a drug delivery approach for restricting the passage of small molecules across the blood-brain barrier. This allows us to develop naloxone- and oxycodone-based conjugates that display superior potency, peripheral selectivity, pharmacokinetics, and efficacy in rats compared …

Reverse-Coded Items Do Not Work In Spanish: Data From Four Samples Using Established Measures, Amanda Venta, Cassandra A. Bailey, Jesse Walker, Alfonso Mercado, Cecilia Colunga-Rodríguez, Mario Ángel-González, Gabriel Davalos-Picazo

Psychological Science Faculty Publications

The potential for suboptimal psychometric performance of reverse-coded items may be particularly pronounced when scales are translated and administered in Spanish with these problems exacerbated in youth respondents. This is a significant concern, given the rapid rise in Hispanic-American and Spanish-speaking individuals in the US and their rightful, growing representation in psychological research and clinical care. The aim of this study was to examine the psychometric performance of reverse-coded items across four Spanish-speaking samples spanning developmental stages including youth, college students, and parents (N = 1,084; Adolescents n = 107; M = 19.79; SD = 2.09; 41.1% female; Caregivers …

My Authentic Self: Rousseau And The Ethics Of Authenticity In The Age Of Gender Ideology, Steven Kessler

Journal of Ideology

This article examines the origins of the contemporary iteration of gender ideology pervasive in the western world today. To accomplish this, the article is broken into three main components. The first component examines the source of where the current trend in picking pronouns, genders, and sexual orientations emanates from. This is attributed to an ideology called, “the ethics of authenticity.” The tenets of the ethics of authenticity are delineated in the article. Another component of the article attributes the origin of authenticity to the work and thought of Jean Rousseau. Specifically, four of his works are examined as fundamentally important …

We Can Update Our Own Stories: Trans*-Informed Principles For Gender-Inclusive Science Teaching., K. Ren Rende

Teacher Education Faculty Publications

Across the United States, Anti-LGBTQ curriculum laws are being passed in staggering numbers, impacting an estimated 25 million children. At a time where a majority of LBGTQ students report feeling unsafe at school, a significant education challenge is how to meet the needs of these students while addressing and dismantling the way the institution of science education continues to uphold systems of oppression. While there have been waves of LGBTQinclusive science education reform, these movements have been stymied by a lack of cohesive guidelines for practice and are generally limited in their inclusion of considerations that attend to the needs …

Lahontan Cutthroat Trout (Oncorhynchus Clarkii Henshawi) And Paiute Cutthroat Trout (Oncorhynchus Clarkii Seleniris) Detection From Environmental Dna Samples: A Dual-Purpose Assay, Thomas W. Franklin, Joseph C. Dysthe, Helen Neville, Michael K. Young, Kevin M. Mckelvey, Michael K. Schwartz

Western North American Naturalist

Lahontan cutthroat trout (Oncorhynchus clarkii henshawi) and Paiute cutthroat trout (Oncorhynchus clarkii seleniris) are rare taxa of conservation concern. Their generally low population densities and remote distribution make traditional sampling difficult, but they primarily exist in small streams, a habitat type where environmental DNA (eDNA) sampling has proven extremely effective. We developed a single eDNA assay that allows sensitive detection of both taxa, which occur separate from each other in different regions of the Lahontan Basin. Performance of the assay was evaluated using most lineages of Lahontan cutthroat trout and Paiute cutthroat trout as well as …

A Mathematical Model Of Glut1 Modulation In Rods And Rpe And Its Differential Impact In Cell Metabolism, Andrea Aparicio, Erika T Camacho, Nancy J. Philp, Stephen A Wirkus

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

We present a mathematical model of key glucose metabolic pathways in two cells of the human retina: the rods and the retinal pigmented epithelium (RPE). Computational simulations of glucose transporter 1 (GLUT1) inhibition in the model accurately reproduce experimental data from conditional knockout mice and reveal that modification of GLUT1 expression levels of both cells differentially impacts their metabolism. We hypothesize that, under glucose scarcity, the RPE’s energy producing pathways are altered in order to preserve its functionality, impacting the photoreceptors’ outer segment renewal. On the other hand, when glucose is limited in the rods, aerobic glycolysis is preserved, which …
