Translational Pharmacokinetic-Pharmacodynamic Modeling And Simulation In The Development Of Spectinamides, A Novel Class Of Anti-Tuberculosis Agents, Chetan Rathi

Theses and Dissertations (ETD)

New chemotherapeutic agents are urgently needed to control the spread of multidrug-resistant (MDR) and extensively drug-resistant (XDR) forms of tuberculosis, which still remains an important public health challenge globally. Recently, spectinamides have emerged as a novel class of anti-tuberculosis agents that overcomethe native drug efflux. Spectinamides bind to the 30S bacterial ribosomal subunit which interferes with ribosomal translocation, and ultimately results in inhibition of protein synthesis. They have potent in vitro activity against drug resistant Mycobacterium tuberculosis (Mtb), and also demonstrated sustained efficacy in (Mtb)-infected mouse models. Pharmacokinetic (PK)/ pharmacodynamic (PD) analyses play a critical role in identifying …

School of Medicine Publications

Polyunsaturated fatty acids (PUFA) contained in fish oil (FO) are ligands for peroxisome proliferator-activated receptors (PPAR) that may induce changes in cardiometabolic markers. Variation in PPAR genes may influence the beneficial responses linked to FO supplementation in young adults. The study aimed to analyze the effect of FO supplementation on glucose metabolism, circulating lipids and inflammation according to PPARα L162V and PPARγ2 P12A genotypes in young Mexican adults. 191 young, non-smoking subjects between 18 and 40 years were included in a one-arm study. Participants were supplemented with 2.7 g/day of EPA+DHA, during six weeks. Dietary analysis, body composition measurements and …

Transcranial Direct Current Stimulation And Sports Performance, Dylan J. Edwards, Mar Cortes, Susan Wortman-Jutt, David Putrino, Marom Bikson, Gary Thickbroom, Alvaro Pascual-Leone

Research outputs 2014 to 2021

The application of transcranial direct current stimulation (tDCS) hasmoved fromthe laboratory to the wider community. This form of non-invasive brain stimulation has been shown in a number of controlled animal and human experiments, over nearly five decades, to modulate brain physiology, cognitive functions, and behavior. While its effects are variable across and within individuals, it is not unreasonable to state that tDCS harbors the potential to enhance executive and physical human performance. In a society increasingly driven to succeed with less effort, performance enhancement with an intervention that has an excellent safety record, is well tolerated, relatively inexpensive and readily …

A Review Of Ankylosing Spondylitis, Hannah L. Owen

Senior Honors Theses

Ankylosing spondylitis (AS) is a systemic autoimmune disorder that induces ankylosis of the spine (fusion of the vertebrae at their various joints) and inflammatory arthritis of peripheral joints among other symptoms. Overexpression of cytokines, the presence of genetic mutations not exclusive to the human leucocyte antigen (HLA)-B27 region, and environmental factors all have large roles in the progressive development of AS. Although a definitive pathology continues to be sought after, researchers believe the adaptive immune system in AS patients attacks fibrocartilaginous entheses (supportive connective tissue between bone and attached structures like tendon, ligament, and fascia).

AS markedly reduces proper systemic …

McNair Research Journal SJSU

Introduction: Research has found that HIV-related stigma has numerous negative impacts on the lives of people living with HIV (PLWH). Although there are more resources than ever dedicated to HIV/AIDS efforts, stigma continues to be a major factor challenging the prevention and treatment of HIV today. Understanding the impacts of stigma on health outcomes and quality of life in PLWH is essential to address the global HIV epidemic and reduce health disparities.

Search Strategy: We conducted a secondary meta-analysis of existing research that discussed and evaluated the impacts of HIV-related stigma and discrimination on PLWH. We searched the following databases …

Creation Of An Immunodeficient Hla-Transgenic Mouse (Humamice) And Functional Validation Of Human Immunity After Transfer Of Hla-Matched Human Cells, Yang Zeng, Bingrun Liu, Marie-Therese Rubio, Xinyue Wang, David M. Ojcius, Ruoping Tang, Antoine Durrbach, Zhitao Ru, Yusen Zhou, Yu-Chun Lone

All Dugoni School of Dentistry Faculty Articles

Research on human immunology has been hindered by the lack of optimal small animal models, given that the protective immune responses of human and non-human species show significant differences. However, due to ethical constraints[1] and the high cost of clinical trials, it is urgent to improve the current animal models that can mimic faithfully human physiology, particularly the human immune system (HIS). HIS mice had been generated recently by engrafting human hematopoietic stem cells (hHSCs) or human peripheral mononuclear cells (hPBMCs) into highly immuno-deficient mice such as NSG, NOG or NRG mice. However, a major experimental drawback for studies using …

Lactose Intolerance: An Overview Of The Facts And Their Implications, Noelle M. Yeo

Honors Program: Senior Projects (Public)

Lactose intolerance is often blamed for the symptoms such as bloating, diarrhea, gas, abdominal pain, and nausea, that ail many people. Patients often do not seek proper diagnosis from a physician and create their own treatment plans, severely restricting lactose intake, without professional guidance. Even those who do seek the care of a physician find that diagnosis is complicated by less-than ideal testing and confusion due to the symptoms common to many other conditions. The misconceptions and inability to confirm a diagnosis of lactose intolerance can cause nutrient deficiencies in these patients, as well as begin a pattern of unnecessary …

Ecological Correlations Of Dietary Food Intake And Mental Health Disorders, Jordan Hoerr, Joshua Fogel, Benjamin Van Voorhees

Publications and Research

This paper examines the ecological association of dietary food intake with mental health outcomes on the group level across countries. Published data from the World Mental Health Survey were used to compare lifetime prevalence of four categories of mental health disorders (anxiety disorders, mood disorders, impulse control disorders, and substance use disorders) with a country’s fish/seafood and sugar/sweetener supply quantity using the Spearman rank correlation. Data were compared for 17 countries across the world. Sugar and sweetener supply quantity was significantly and positively associated with anxiety disorders (rho = 0.75, p = 0.001), mood disorders (rho = 0.75, p = …

Employing The Enzyme Cofactor Function Of Ascorbic Acid To Affect Oncogenic Pathways In Human Melanoma: Modulating Hypoxia Inducible Factor-1Α And Dna Demethylation To Reduce Malignant Potential, Adam Patrick Fischer

Theses, Dissertations and Capstones

Dioxygenase enzymes such as the HIF hydroxylases (PHD1-3, FIH) and the Ten-eleven translocation (TET1-3) enzymes regulate the activity of the hypoxia inducible factor-1_a (HIF1_a) transcription factor and the DNA methylation status of cells, respectively. Aberrant accumulation and activation of HIF-1_a can allow malignant cells to acquire attributes that promote progression, chemotherapy resistance, and survival, while aberrant hypermethylation of gene promoters can silence the expression of tumor suppressor genes essential to preventing tumorigenesis. Inadequate levels of intracellular ascorbic acid (AA), a necessary cofactor for optimal dioxygenase enzyme function, could potentiate these tumorigenic conditions. In fact, plasma levels …

Using Nursing Simulation To Improve Early Recognition Of Emergent Situations, Carlene Blais

Walden Dissertations and Doctoral Studies

Nurses' ability to recognize and respond to postoperative patients who require emergent medical care and need immediate assistance during a code blue in the first 10 minutes is essential to improve patient outcomes. This is particularly important for the project site, a 44-bed inpatient surgical specialty hospital located in the Northeast, providing care for patients with head and neck cancer, as the hospital does not have an internal code blue response team. An adjacent facility responds to all code blue emergencies and takes approximately 10 minutes for the team to respond. The purpose of this DNP project was to develop …

Nitrosative Stress Sensing In Porphyromonas Gingivalis: Structure And Function Of The Heme Binding Transcriptional Regulator Hcpr, Benjamin R. Belvin

Theses and Dissertations

Porphyromonas gingivalis, a Gram negative anaerobe implicated in the progression of periodontal disease, is capable of surviving and causing infection despite high levels of reactive nitrogen species found in the oral cavity due to its efficient nitrosative stress response. HcpR is an important sensor-regulator that plays a vital step in the initiation of the nitrosative stress response in many Gram negative anaerobic bacteria. We employ a combination of X-ray crystallography, SAXS, resonance Raman spectroscopy, UV-Vis spectroscopy, and molecular biology techniques to better understand this key regulator. Knockout of the hcpR gene in W83 P. gingivalis results in the inability of …

The Role Of N-Myc Downstream Regulated Gene 1 In Breast Cancer Lipid Metabolism, Christopher James Sevinsky

Legacy Theses & Dissertations (2009 - 2024)

Altered carbohydrate and lipid metabolism are increasingly well characterized hallmarks of aggressive breast cancers. While aerobic glycolysis, or “the Warburg effect”, is a well-established metabolic adaptation exploited by tumor cells, the understanding of unique aspects of cancer lipid metabolism lags behind. This is especially true regarding the coordination of complex lipid synthesis and trafficking pathways, which remains poorly understood. N-Myc Downstream Regulated Gene1 (NDRG1) is overexpressed in many solid tumors, but its function is unclear. The importance of NDRG1 is best exemplified by the effect of null mutations on human physiology: inactivating mutations give rise to the severe autosomal recessive …

The Role Of Hur In Astrocytes In Spinal Cord Injury, Thaddaeus Kwan

All ETDs from UAB

Neuroinflammation is a defining event during the acute phase of spinal cord injury (SCI). The inflammatory cascade is initiated by activated glial cells such as astrocytes and microglia in the milieu of the injured tissue through release of pro-inflammatory cytokines, matrix metalloproteinases, and reactive oxygen species. These soluble factors produce cytotoxicity to neurons and other cells either directly or indirectly by promoting permeabilization of the blood-spinal cord barrier, edema and subsequent ischemia. These factors also serve to recruit and activate additional glia and peripheral immune cells. The mRNAs of many of these soluble factors such as TNFα, IL-1β, CXCL1, and …

Single Low-Dose Lipopolysaccharide Preconditioning: Neuroprotective Against Axonal Injury And Modulates Glial Cells, Ryan C. Turner, Zachary J. Naser, Brandon P. Lucke-Wold, Aric F. Logsdon, Reyna L. Vangilder, Rae Reiko Matsumoto, Jason D. Huber

Faculty Publications & Research of the TUC College of Pharmacy

AIM: Over 7 million traumatic brain injuries (TBI) are reported each year in the United States. However, treatments and neuroprotection following TBI are limited because secondary injury cascades are poorly understood. Lipopolysaccharide (LPS) administration before controlled cortical impact can contribute to neuroprotection. However, the underlying mechanisms and whether LPS preconditioning confers neuroprotection against closed-head injuries remains unclear.

METHODS: The authors hypothesized that preconditioning with a low dose of LPS (0.2 mg/kg) would regulate glial reactivity and protect against diffuse axonal injury induced by weight drop. LPS was administered 7 days prior to TBI. LPS administration reduced locomotion, which recovered completely …

Issues Related To Implementing High-Fidelity Simulation In A Nursing Program, Sherry Rene Ray

Walden Dissertations and Doctoral Studies

Due to the shortage of clinical sites, nursing educators, deans, and directors are compelled to implement alternative clinical solutions such as high-fidelity simulation (HFS). The problem is that nursing educators are often not prepared to implement HFS as a teaching strategy. Faculty readiness is imperative for a successful simulation program and student outcomes. Therefore, the purpose of this study was to investigate the perceptions and practices of faculty, deans, and directors on the implementation of HFS across the nursing curriculum. Kolb's experiential learning theory provided the theoretical support for both the teaching and learning required by faculty for a successful …

Mechanisms Of Hormonal Regulation Of Invasiveness And Metastasis Of Luminal Breast Cancer, Thomas Mcfall

ABSTRACT

MECHANISMS OF HORMONAL REGULATION OF INVASIVENESS AND METASTASIS OF LUMINAL BREAST CANCER

By

THOMAS MCFALL

December 2017

Advisor: Dr. Manohar Ratnam

Major: Cancer Biology

Degree: Doctor of Philosophy

Over 20% of breast cancer cases present with distal metastasis and they are predominantly of luminal subtypes. As luminal breast cancer is relatively indolent, it is believed that progression to metastasis must occur over many years, generally well into post-menopausal years. Unfortunately, very little is known about the mechanisms by which these hormone receptor positive tumors metastasize, likely in part due to their slow metastatic rates in animal model systems as …

Hydrogen Sulfide Regulation Of Kir Channels, Junghoon Ha

Theses and Dissertations

Inwardly rectifying potassium (Kir) channels establish and regulate the resting membrane potential of excitable cells in the heart, brain and other peripheral tissues. Phosphatidylinositol- 4,5-bisphosphate (PIP2) is a key direct activator of ion channels, including Kir channels. Gasotransmitters, such as carbon monoxide (CO), have been reported to regulate the activity of Kir channels by altering channel-PIP2 interactions. We tested, in a model system, the effects and mechanism of action of another important gasotransmitter, hydrogen sulfide (H2S) thought to play a key role in cellular responses under ischemic conditions. Direct administration of sodium hydrogen sulfide (NaHS), as an exogenous H2S source, …

A Mathematical Investigation On Tumor-Immune Dynamics: The Impact Of Vaccines On The Immune Response, Jonathan Quinonez, Neethi Dasu, Mahboob Qureshi

College of Osteopathic Medicine (TUN) Publications and Research

Mathematical models analyzing tumor-immune interactions provide a framework by which to address specific scenarios in regard to tumor-immune dynamics. Important aspects of tumor-immune surveillance to consider is the elimination of tumor cells from a host’s cell-mediated immunity as well as the implications of vaccines derived from synthetic antigen. In present studies, our mathematical model examined the role of synthetic antigen to the strength of the immune system. The constructed model takes into account accepted knowledge of immune function as well as prior work done by de Pillis et al. All equations describing tumor-immune growth, antigen presentation, immune response, and interaction …

Using The Medication Cabinet To Predict Fall Risk In Elderly Adults, Jessica Lopez

University of the Pacific Theses and Dissertations

Background: In the United States, 30-60% of older adults fall each year; 10-20% of these falls result in injury, hospitalization, or even death. Better prevention of falls in this population may be facilitated by broader identification of risk factors. The use of statins has emerged as a potential risk factor, but the data provide conflicted results.

Purpose: To examine the relationship between statin use and falls among community-dwelling older adults.

Methods: We evaluated the patient registry of a Level 1 trauma center. All patients aged > 50 years who were admitted for falls in 2015 were included (n=615). Many of these …

Computational Fluid Dynamics In A Terminal Alveolated Bronchiole Duct With Expanding Walls: Proof-Of-Concept In Openfoam, Jeremy Myers

Theses and Dissertations

Mathematical Biology has found recent success applying Computational Fluid Dynamics (CFD) to model airflow in the human lung. Detailed modeling of flow patterns in the alveoli, where the oxygen-carbon dioxide gas exchange occurs, has provided data that is useful in treating illnesses and designing drug-delivery systems. Unfortunately, many CFD software packages have high licensing fees that are out of reach for independent researchers. This thesis uses three open-source software packages, Gmsh, OpenFOAM, and ParaView, to design a mesh, create a simulation, and visualize the results of an idealized terminal alveolar sac model. This model successfully demonstrates that OpenFOAM can be …

Vmed 646: Animal Physiology Ii—A Peer Review Of Teaching Project Benchmark Portfolio, Renee M. Mcfee

UNL Faculty Course Portfolios

This Peer Review of Teaching Project portfolio focuses on the Animal Physiology II course which is required for first year veterinary medicine students. Weekly quizzes assess baseline knowledge and had been administered individually and in groups. I hypothesized the discontinuation of group quizzes would increase student effort when preparing for quizzes. Unit exams involve scenario-based questions and require students to apply information. I hypothesized the implementation of group exams would help under-performing students improve their ability to apply information they had learned. Exams were still taken individually prior to being taken in groups to encourage adequate preparation. Student impacts were …
