Preying On The Desperate, Karen M. Savage

Capstones

In this story, I investigate the marketing and sale of concentrated hydrogen peroxide to individuals who are desperate to cure serious health maladies. The story follows an online marketer who was warned by the FDA more than ten years ago to stop claiming hydrogen peroxide ingestion could cure cancer and other ailments. But in spite of the warning and subsequent FDA investigation, the individual continues to claim high strength hydrogen peroxide helps with brain tumors and leukemia and he can now be tied to several different websites marketing various “brands” of high strength hydrogen peroxide. Another marketer distributes hydrogen peroxide …

Development Of Cxcr4-Inhibiting Nanoparticles For The Treatment Of Metastatic Cancer, Yan Wang

Theses & Dissertations

Metastasis is the main cause of cancer mortality and morbidity, leading to several million deaths every year. Less than 20% of pancreatic cancer (PC) patients are candidates for surgery due to spread beyond the pancreas. Desmoplasia presents substantial barriers to perfusion, diffusion, and convection of antitumor therapeutics into the PC tissues. We focus on developing novel therapies that regulates tumor microenvironment, chemosensitizing tumor to therapeutics and preventing metastasis.

Gene therapy is emerging as a promising new therapeutic agents for cancer treatment. A targeted, systemic, effective and safe gene delivery system should be developed. CXCR4/SDF-1 axis plays a crucial role in …

Elucidating The Effects Of Metabolic State On Nanoparticle Distribution In Mice And In Vitro Uptake, Kevin James Quigley

Doctoral Dissertations

Since almost 70% of the U.S. population over 20 years old is overweight and 30% is obese, with much of the western world following suit, many patients that will potentially be administered circulating nanoparticles designed to localize to tumors and avoid non-target areas will have significant amounts of white adipose tissue (WAT), enlarged livers, and additional metabolic complications such as type 2 diabetes. However, studies on nanoparticle biodistribution and efficacy take place almost without exception in lean rodents with healthy metabolic states. In this work, I determined the biodistribution of model nanoparticles – neutral filomicelles and polystyrene spheres both carrying …

Stroke As A First Presentation Of Malignancy, Farheen Niazi, Puneet Kakar, Ratneshwari Jha, Reena Dhami, Farook Edoo

Pakistan Journal of Neurological Sciences (PJNS)

Stroke is a frequent complication in patients with cancer occurring in nearly 15% of the cases. However cerebrovascular disease as the first presentation of malignancy has rarely been reported. We report two such cases who were admitted with acute stroke but were later on found to be having malignancy. Routine workup was unrewarding in both patients. Both patients developed pulmonary embolism as well during hospital stay suggesting hypercoagulable state as likely etiology. Reaching to the final diagnosis was an arduous journey but can help guide other clinicians facing similar cases. Non Hodgkins B cell lymphoma and Carcinoma Gall bladder were …

The Oncolytic Potential Of Tanapoxvirus To Treat Retinoblastoma, John D. Christie

Masters Theses

Retinoblastoma is the leading cause of intraocular malignancy in children under 2 years of age. Current treatments, while generally effective in eliminating the tumor, have many negative side effects. Oncolytic virotherapy is the use of either wild type or recombinant viruses, to destroy tumor cells. There are currently several viruses being engineered as potential therapeutics for a wide range of cancers. They offer tumor specific alternative to current therapies with lesser toxicity. This study looked at the oncolytic efficacy of multiple tanapoxviruses (TPV) recombinants in an in vitro retinoblastoma. Here we have tested recombinants of TPV for their ability to …

Establishing A Clinically Relevant Mouse Model Of Human Aml To Test Novel Transmethylation Inhibitors., Aditya Barve

Electronic Theses and Dissertations

Acute myeloid leukemia (AML) is a highly heterogeneous clonal disorder characterized by an accumulation of malignant immature myeloid progenitors in the bone marrow (BM) that hinder normal hematopoiesis. Patient AML exhibits a dramatic heterogeneity in terms of cytogenetics, disease morphology, and associated prognoses and/or chemotherapeutic sensitivity. Thus it becomes clearly evident that the investigation of novel therapeutics for AML will require model systems that are capable of recapitulating this stark heterogeneity in a patient specific manner. Furthermore, it is now understood that the surrounding bone marrow (BM) microenvironment and supporting cells play a critical role in leukemic progression as well …

Current And Emerging Uses Of Statins In Clinical Therapeutics: A Review, Jonathan T. Davies, Spencer F. Delfino, Chad E. Feinberg, Meghan F. Johnson, Veronica L. Nappi, Joshua T. Olinger, Anthony P. Schwab, Hollie I. Swanson

Pharmacology and Nutritional Sciences Faculty Publications

Statins, a class of cholesterol-lowering medications that inhibit 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase, are commonly administered to treat atherosclerotic cardiovascular disease. Statin use may expand considerably given its potential for treating an array of cholesterol-independent diseases. However, the lack of conclusive evidence supporting these emerging therapeutic uses of statins brings to the fore a number of unanswered questions including uncertainties regarding patient-to-patient variability in response to statins, the most appropriate statin to be used for the desired effect, and the efficacy of statins in treating cholesterol-independent diseases. In this review, the adverse effects, costs, and drug–drug and drug–food interactions associated with statin …

Targeted And Controlled Anticancer Drug Delivery And Release With Magnetoelectric Nanoparticles, Alexandra Rodzinski

FIU Electronic Theses and Dissertations

A major challenge of cancer treatment is successful discrimination of cancer cells from healthy cells. Nanotechnology offers multiple venues for efficient cancer targeting. Magnetoelectric nanoparticles (MENs) are a novel, multifaceted, physics-based cancer treatment platform that enables high specificity cancer targeting and externally controlled loaded drug release. The unique magnetoelectric coupling of MENs allows them to convert externally applied magnetic fields into intrinsic electric signals, which allows MENs to both be drawn magnetically towards the cancer site and to electrically interface with cancer cells. Once internalized, the MEN payload release can be externally triggered with a magnetic field. MENs uniquely allow …

The objective of this study was to examine the mammography and Papanicolaou (Pap) smear screening practices among women within the United States, and to determine predictors of screening.

Methods: Data from the 2012 and 2014 Behavioral Risk Factor Surveillance System were used. The association between demographic predictors (age, marital status, education level, employment status, income, health insurance, and medical cost …

The Lived Experience Of Fathers With Advanced Cancer, Maria Mowassee

Dissertations, Theses, and Capstone Projects

Historically, fathers have been neglected as a research population in the nursing and oncology literature. This was in relation to their role being viewed as a disciplinarian and breadwinner instead of a nurturer. Fast-forward to modern day society, their role has evolved into a more involved parent that is necessary for their child’s development and well-being. The literature has also evolved and in recent years, this population has been gaining recognition and it is of great importance to understand their role, perception, and concerns as it pertains to being involved fathers. Therefore, when considering fathers with advanced cancer when death …

An Examination Of Chimpanzee Use In Human Cancer Research, Jarrod Bailey

Jarrod Bailey, PhD

Advocates of chimpanzee research claim the genetic similarity of humans and chimpanzees make them an indispensable research tool to combat human diseases. Given that cancer is a leading cause of human death worldwide, one might expect that if chimpanzees were needed for, or were productive in, cancer research, then they would have been widely used. This comprehensive literature analysis reveals that chimpanzees have scarcely been used in any form of cancer research, and that chimpanzee tumours are extremely rare and biologically different from human cancers. Often, chimpanzee citations described peripheral use of chimpanzee cells and genetic material in predominantly human …

Psychological Aspects Of Head And Neck Cancer, Katherine Rieke

Theses & Dissertations

Patients with head and neck cancer may be at increased risk for depression diagnosis when compared to other cancer sites, both before and after their cancer diagnosis. Behavioral risk factors for head and neck cancers, including tobacco and alcohol use, may be indicative of depression before cancer diagnosis. Further, head and neck cancers and their treatments can cause serious morbidity among patients, including physical disfigurement and loss of function. Additionally, these cancers are often accompanied by social stigma, personal shame, and guilt. While there is a significant body of research examining depression in this cancer population, there are still several …

State Space Analysis Of Dominant Structures In Dynamic Social Systems, Jeremy B. Sato

McKelvey School of Engineering Theses & Dissertations

Many systems involving human relationships are modeled as dynamic systems, as diverse as urban population growth, diffusion of innovations, spread of viruses, and supply chain management. A fundamental assumption is that these systems contain variables which accumulate and deplete over time (people, innovation adoptions, infections, and orders), and whose dynamics are determined by societal rules and human decision making processes. These assumptions allow the system to be formally expressed by ordinary differential equations which are often nonlinear and contain multiple state variables and feedback loops. Analytical methods have been developed to identify the dominant feedback loops which primarily influence the …

Pharmacy Faculty Articles and Research

A series of cyclic peptides containing a number of tryptophan (W) and glutamic acid (E) residues were synthesized and evaluated as pH-sensitive agents for targeting of acidic tissue and pH-dependent cytoplasmic delivery of molecules. Biophysical studies revealed the molecular mechanism of peptides action and localization within the lipid bilayer of the membrane at high and low pHs. The symmetric, c[(WE)4WC], and asymmetric, c[E4W5C], cyclic peptides translocated amanitin, a polar cargo molecule of similar size, across the lipid bilayer and induced cell death in a pH- and concentration-dependent manner. Fluorescently-labelled peptides were evaluated for targeting of acidic 4T1 mammary tumors in …

Nanobubbles Provide Theranostic Relief To Cancer Hypoxia, Christopher M. Long, Pushpak N. Bhandari, Joseph Irudayaraj

The Summer Undergraduate Research Fellowship (SURF) Symposium

Hypoxia is a common motif among tumors, contributing to metastasis, angiogenesis, cellular epigenetic abnormality, and resistance to cancer therapy. Hypoxia also plays a pivotal role in oncological studies, where it can be used as a principal target for new anti-cancer therapeutic methods. Oxygen nanobubbles were designed in an effort to target the hypoxic tumor regions, thus interrupting the hypoxia-inducible factor-1α (HIF-1α) regulatory pathway and inhibiting tumor progression. At less than 100nm, oxygen nanobubbles act as a vehicle for site-specific oxygen delivery, while also serving as an ultrasound contrast agent for advanced imaging purposes. Through in vitro and in vivo studies, …

The Roles Of Nuclear Receptor Nr4a1 In Cancer Cell Proliferation And Skeletal Muscle Differentiation, Alexa Farmer

Theses and Dissertations (ETD)

Nuclear receptors (NRs) constitute a major class of drug targets in the treatment of various cancer types. NRs respond to cellular signals and become activated upon ligand binding to transcriptionally modulate expression of target genes. NR4A1 (Nur77) is a member of the NR4A family of nuclear receptors and displays an oncogenic profile in many cancer models. It is often upregulated in adult solid malignancies and is known to promote cell proliferation and survival. Knockdown studies of NR4A1 in cancer cell lines results in decreased cell growth and angiogenesis and increased apoptosis, suggesting NR4A1 is an oncogenic protein. Due to the …
