Combination Therapy: Parp Inhibitor Synergizes The Therapeutic Efficacy Of Doxorubicin In The Treatment Of Prostate Cancer, Momin Ansare

Electronic Theses & Dissertations

Men are most susceptible to prostate cancer in the United States. The general treatment options include surgery, hormone therapy, chemotherapy, and radiation therapy. But in recent days, the nanoformulation have shown promising applications in overcoming the drawbacks of the currently available treatment options. To complement, we tried to enhance the capability of the nanoparticle formulation by loading them with a novel drug combination for the treatment of prostate cancer. Herein, we synthesized folate conjugated iron oxide nanoparticles encapsulated with doxorubicin and olaparib for imaging and targeted treatment of prostate cancer. Both drugs are approved by FDA for clinical cancer treatment. …

Synthesis Of Doxorubicin-Based Prodrug And Activatable Mr Nanoprobe For The Imaging And Treatment Of Cancer, Bayan Dous

Electronic Theses & Dissertations

Magnetic Resonance Imaging (MRI) is increasingly being used as a diagnostic tool for cancer. We propose a novel molecular probe, Gadolinium-DTPA disulfide-bonded Doxorubicin (Gd-DTPA-SS-Doxo) encapsulated in iron oxide which could provide a dual modality for detecting malignant growth while simultaneously targeting treatment options. We first synthesized Gd-DTPA-SS-Doxo followed by encapsulation within the poly (acrylic acid) (PAA) coating of iron oxide nanoparticle (IONP), producing a nanoprobe (IO-Gd-DTPA-SS-Doxo) with quenched longitudinal spin lattice magnetic relaxation (T1). After receptor-mediated internalization, Gd-DTPA-SS-Doxo is released from the nanoprobe’s polymeric coating due to the acidic microenvironment of the tumor. When the molecular probe is subjected to …

Toward An Understanding Of Grb Prompt Emission Mechanism. Ii. Patterns Of Peak Energy Evolution And Their Connection To Spectral Lags, Z. Lucas Uhm, Bing Zhang, Judith Racusin

Physics & Astronomy Faculty Research

The prompt emission phase of gamma-ray bursts (GRBs) exhibits two distinct patterns of the peak energy (E p ) evolution, i.e., time-resolved spectral analyses of νF ν spectra of broad pulses reveal (1) "hard-to-soft" and (2) "flux-tracking" patterns of E p evolution in time, the physical origin of which still remains not well understood. We show here that these two patterns can be successfully reproduced within a simple physical model invoking synchrotron radiation in a bulk-accelerating emission region. We show further that the evolution patterns of the peak energy have, in fact, direct connections to the existence of two different …

The Effect Of Wall Cooling And Heating On Görtler Vortices In High-Speed Boundary Layers, Safae El Amrani

Theses and Dissertations

The development of the so-called Görtler vortices in boundary layer flows over a concave surface leads to strong velocity gradients in both wall-normal and spanwise directions. This determines the flow structures to become more prone to secondary instabilities, which prompt to an early transition from laminar to turbulent flow, ultimately increasing the frictional drag. It is possible to circumvent these secondary instabilities by means of passive or active flow control strategies, with sensors and actuators implemented at the wall. In this thesis, the effect of wall cooling and heating on Görtler vortices developing in supersonic and hypersonic boundary layers is …

An Autoethnography Of Culturally Relevant Leadership As Moral Practice: Lived Experiences Through A Scholar-Practitioner Lens, Charles L. Lowery

The Qualitative Report

In this autoethnography, I am concerned with cultural relevance as an experience of a scholar-practitioner educational leader. I question my own cultural competence as a teacher and school principal. Turning a reflective gaze on my lived experiences as an educator creates a space in which I attempt to make meaning of the phenomenon of culturally relevant practices in the field of education. As an act of pedagogical and personal meaning-making, this autoethnographic work centers on the value of cultural relevance as informed by scholarly practice.

Afterschool Educators' Teaching Practices Through Tinkering: Nurturing Student Collaboration, Engagement, And Development Of Self-Confidence, Lianna Kali

Master's Theses

Since the early 2000s constructionist pedagogy has become an increasingly popular trend in both formal and informal science, technology, engineering, art, and math (STEAM) learning environments to support transformative educational outcomes through the making of personally meaningful objects and artifacts. But with this rise in popularity comes a challenge for educators: understanding what are the teaching practices that are most effective in a maker-centered learning environment to support student learning. Through an ethnographic case study of the teaching practices in a tinkering afterschool program, this study examines the core pedagogical facilitation moves of tinkering educators and investigates how those moves …

Detection And Melting Of Surface-Bound Dna Using A Purely Electrochemical Approach, Denny Ho

Master's Theses

In this thesis, we demonstrate an electrochemical approach for monitoring the electric-field induced melting of surface-bound double-stranded DNA. The electrochemical routine involves repeated chronoamperometry pulses to melt the duplex and square wave voltammetry to monitor the extent of melting. We utilize a scanning potential and constant potential technique to generate melting curves and access the stability and kinetics of the DNA duplexes. Our method uses a mixed monolayer of thiol-modified DNA oligomers and mercaptohexanol on gold electrodes, are subsequently incubated with target DNA covalently modified with electroactive methylene blue. Under room temperature, 10 mM Tris, and optimized electrochemical parameters, DNA …

Electropolymerization Of Polyaniline In The Presence Of Ferricyanide: Electrochemical, Spectroscopic And Gravimetric Studies, Lucas Marinelli

Master's Theses

In this work, ferricyanide-doped polyaniline (PANI) is electropolymerized by constant current and cyclic voltammetry (CV) measurements with simultaneous monitoring of mass changes using electrochemical quartz crystal microbalance (eQCM). Raman spectroscopy, Fourier transform infrared spectroscopy and CV measurements confirm the incorporation of the ferricyanide into the film and indicate modified electrical conductivity. UV-Vis absorbance spectroscopy and Raman spectroscopy confirm the conducting ‘emeraldine-salt’ state and confirm the presence of polarons, i.e. charge carriers.

The addition of ferricyanide during electropolymerization of the PANI film results in an increase of polymerization rate as confirmed using eQCM. A decrease in counter ion ingress/egress and an …

Distributed Predictive Control For Mvdc Shipboard Power System Management, Nasibeh Zohrabi

Theses and Dissertations

Shipboard Power System (SPS) is known as an independent controlled small electric network powered by the distributed onboard generation system. Since many electric components are tightly coupled in a small space and the system is not supported with a relatively stronger grid, SPS is more susceptible to unexpected disturbances and physical damages compared to conventional terrestrial power systems. Among different distribution configurations, power-electronic based DC distribution is considered the trending technology for the next-generation U.S. Navy fleet design to replace the conventional AC-based distribution. This research presents appropriate control management frameworks to improve the Medium-Voltage DC (MVDC) shipboard power system …

An Experimental Method For Testing Materials At The Intermediate Strain Rate With Closed Loop Control, Cory N. Krivanec

Theses and Dissertations

Quasi static and intermediate strain rate (5 s-1 and 500 s-1) tests are conducted on various aluminum and steel ASTM E8 subsize tensile specimens to validate a newly developed testing method which combines a previously developed serpentine bar for load monitoring and a newly described high-speed actuator. This new actuator is controlled by a semi-passive piezoelectrically actuated brake system mounted to a standard actuator, which allows for the actuator to produce high loads and quick response times (≈100 µs). Limitations of this experimental method are that tests must be monotonic (tension or compression but not cyclic loading) and strain rate …

Using Geospatial Techniques To Assess Responses Of Black Bear Populations To Anthropogenically Modified Landscapes: Conflict & Recolonization, Jamie Elizabeth Mcfadden

Theses and Dissertations

The convergence of three young scientific disciplines (ecology, geospatial sciences, and remote sensing) has generated unique advancements in wildlife research by connecting ecological data with remote sensing data through the application of geospatial techniques. Ecological datasets may contain spatial and sampling biases. By using geospatial techniques, datasets may be useful in revealing landscape scale (e.g., statewide) trends for wildlife populations, such as population recovery and human-wildlife interactions. Specifically, black bear populations across North America vary greatly in their degree of distribution stability. The black bear population in Michigan may be considered stable or secure, whereas the population in Missouri is …

System Dynamics Model Of Necrotic Enteritis And Its Predisposing Factors In Broilers, Yu-Bin Chou

Theses and Dissertations

Necrotic enteritis (NE) caused by Clostridium perfringens type A is an important bacterial enteric disease of global broiler production. However, the dynamic interactions of NE and its predisposing factors are not fully presented by current studies. By using the System Dynamics (SD) Model, the epidemiological changes in susceptible-infected-removed models of NE and avian coccidiosis and their interactions in one or multiple grow-out cycles was established; meanwhile, the growth performance was measured by the average weights of infected and non-infected populations at harvest were estimated. The SD model provided direct and persuasive outcomes of the epidemiology and ecology of NE compared …

Tailoring Math Curricula For Community Colleges: A Process Approach, Ira Lindsay Mcfarland Kinard

Theses and Dissertations

Community college instructors continue to search for effective instructional methods that promote student success in developmental mathematics courses such as intermediate algebra. According to research, mathematics is a major obstacle for students succeeding, persisting, and completing community college programs. Each student enrolled in intermediate algebra has an ACT sub-score of 16 to 18 or an ACCUPLACER sub-score of 57 to 75. Most community colleges in Mississippi use placement testing to determine the strengths and needs of students. However, students approach math with high anxiety, more than any other areas, which interferes with their learning. Research indicates that to improve students’ …

Improving Dropout Rates In Mississippi Schools: A Case Study Examining Effective Dropout Prevention Programs In Mississippi High Schools, Shevonda Williams Truman

Theses and Dissertations

The dropout rate for many Mississippi high schools has improved tremendously over the last decade. In 2017, the Mississippi Department of Education reported that the dropout rate for the State declined form 13.9% to 10%. This rate was only 4% higher than the national average. However, with all the research that pertains to student dropouts and the success many states are seeing, there are still school districts failing to show improvement. Many high schools have dropout rates in excess of 20%. This study explored the perceptions of district high school principals, counselors, and other administrators working in schools with students …

Goodness-Of-Fit Test For Hazard Rate, Ralph Antoine Vital

Theses and Dissertations

In certain areas such as Pharmacokinetic(PK) and Pharmacodynamic(PD), the hazard rate function, denoted by ??, plays a central role in modeling the instantaneous risk of failure time data. In the context of assessing the appropriateness of a given parametric hazard rate model, Huh and Hutmacher [22] showed that their hazard-based visual predictive check is as good as a visual predictive check based on the survival function. Even though Huh and Hutmacher’s visual method is simple to implement and interpret, the final decision reached there depends on the personal experience of the user. In this thesis, our primary aim is to …

Experimental And Numerical Studies Of Lightning Strike Induced Damage To Carbon Fiber Epoxy Composites, Pedram Gharghabi

Theses and Dissertations

The objective of this study is to investigate the interaction between a lightning strike and carbon/fiber composites. The first approach is to characterize the damage development in a composite structure subjected to simulated lightning strikes. Several existing studies have acknowledged that the lightning induced damaged can be categorized into two separate domains of damage; a primary domain of damage that occurs at the attachment point, and a secondary domain of damage that is typically formed around the attachment point. Quantitative studies of the causes of the primary damage domain are not satisfactory for explaining the secondary damage domain and thus, …

False Memories In Recognition Memory: Recollection Or Familiarity?, Alexis E. Payne

Theses and Dissertations

False recollection refers to the retrieval of contextual information associated with an event that has not occurred. For instance, during a recognition task, one might identify a nonstudied word presented at test as old because she remembers the font color of the word during study. Although instances such as this are rare and typically occur at a varying rate of 0-5%, current models of recognition such as the Complementary Learning Systems (CLS) model and the Dual-Process Signal-Detection (DPSD) model do not contain a mechanism to account for their occurrence. Although both the CLS and DPSD models have support from studies …

Facial Expression Recognition By De-Expression Residue Learning, Huiyuan Yang, Umur Ciftci, Lijun Yin

Computer Science Faculty Research & Creative Works

A facial expression is a combination of an expressive component and a neutral component of a person. In this paper, we propose to recognize facial expressions by extracting information of the expressive component through a de-expression learning procedure, called De-expression Residue Learning (DeRL). First, a generative model is trained by cGAN. This model generates the corresponding neutral face image for any input face image. We call this procedure de-expression because the expressive information is filtered out by the generative model; however, the expressive information is still recorded in the intermediate layers. Given the neutral face image, unlike previous works using …
