Population-Based Evaluation Of Treatment Patterns, Drug-Drug Interactions, And Cardiovascular Risk In Patients With Metastatic Castration-Resistant Prostate Cancer, Yue Cheng

Theses and Dissertations--Pharmacy

Prostate cancer has the highest increasing rate and new cases among all cancer in men in the United States and has a higher risk in elderly men. Metastatic castration-resistant prostate cancer (mCRPC) is the late stage of prostate cancer and associated with poor prognosis (median survival 13 months). Androgen deprivation therapy (ADT) use with novel hormone therapy or standard chemotherapy are recommended for mCRPC treatment. Although, the treatment options expanded significantly in recent years, new challenges are present because of the aging population, larger treatment spectrum and co-administrated medication use for other underlying medical conditions, especially for cardiovascular disease (CVD), …

Design And Synthesis Of Small Molecular Inhibitors Of Dcn1-Ube2m Interaction, Tucker J. Moseley

Theses and Dissertations--Pharmacy

Over the last century, advancements in medicine have been made to improve cancer patients' outcomes. The discovery of new druggable targets is essential to achieving this goal. Defective in Cullin Neddylation 1 is a proven oncogenetic driver that may lead to better clinical outcomes when targeted. In efforts to further improve a series of novel small molecular inhibitors of the DCN1 and UBE2M protein-protein interaction, the Guy lab has designed and synthesized 26 new compounds. These compounds were designed to specifically target the UBE2M N-Acetyl sub-pocket on DCN1 that was not occupied by compounds previously described in the literature.

Investigation Of Folate-Poly(Glutamic Acid)/Polyethylenimine/Dna Complexes For In Vitro Gene Delivery, Caleb Akers

Theses and Dissertations--Pharmacy

Gene therapy is currently being studied as a treatment for a variety of indications, including cancer, infectious disease, and cardiovascular diseases, among others. While many of the early treatments in the field involved the use of viral delivery methods, various safety, ethical, and financial concerns limit the potential uses of this methodology. As such, more recent research has focused on developing non-viral delivery platforms to alleviate some of the issues inherent in viral delivery. Recently, the release of the COVID-19 vaccines from Pfizer and Moderna represents a promising use of non-viral delivery as both utilized a lipid-based delivery vector.

Developing A Biocatalytic Toolbox To Aid In Understanding Nucleoside Antibiotics, Jasmine Brianna Woods

Theses and Dissertations--Pharmacy

Antibiotic resistance happens when bacteria develop the ability to survive medications that normally terminate them. Instead, these super germs are able to survive in the body and produce a community of antibiotic resistance germs which can cause human fatalities. It is important to discover and develop new compounds and molecules that will improve this clinical obstacle. This research focused on analyzing the biosynthesis that incorporates distinctive chemical characteristic of various nucleoside antibiotics, ß-hydroxy amino acids and α-methyl-amino acids. ß-hydroxy amino acids and α-methyl-amino acids are considered an important class of industrially useful compounds, particularly for pharmaceutical development, and are found …

New Tools For Biocatalysis: Studies On The Carminomycin 4-O-Methyltransferase Dnrk, Elnaz Jalali

Theses and Dissertations--Pharmacy

Methyltransferases (MTs) are ubiquitous enzymes commonly involved in biosynthesis and regulation. The fundamental goal of this thesis was to explore the permissive nature of methyltransferases and leverage this unique biocatalytic feature to develop a new platform for chemoselective intramolecular cyclization reactions. To realize this ambitious goal, this thesis project set out to probe the substrate specificity of multiple natural product tailoring enzymes (MTs and glycosyltransferases), identify model substrates common to multiple such tailoring enzymes and subsequently establish multi-enzyme tandem reactions that would set the stage for a subsequent chemoselective intramolecular cyclization reaction. Chapter One highlights current state of the art …

Studies Of Polypharmacy And Medication Therapy Management In Population-Based Cohorts, Ximena A. Oyarzun Gonzalez

Theses and Dissertations--Epidemiology and Biostatistics

According to the United States Census Bureau, 16.8% of the population was 65 years and older in 2021, and it is expected that by 2060 that number will increase to about 30% (about 114 million people). Aging is associated with physiological changes in all systems of the body. These changes impact the pharmacodynamics and pharmacokinetic characteristics of drugs. Furthermore, older adults usually have several chronic conditions, which increases their exposure to medications. Increased vulnerability combined with increasing exposure puts elderly people at higher risk for drug interactions and adverse events.

Charlesworth et al. (2014) found that the prevalence of polypharmacy, …

Radiology departments have contributed significantly to greenhouse gases including release of toxic imaging contrast media to environment. We feel Radiology also has several spectroscopy and imaging tools that may apply to monitor and support cleaner environmental goals. The current manuscript is one of the firsts to prompt Radiology to move in that direction by non invasive imaging of bio metals that are less abundant in biological tissues but play key roles as co-factors in tissue structure and function. Conventional analytical tools are mostly invasive and cannot characterize the native oxidation states of bio metals. We chose carbohydrate matrix of metal-rich …

Protective Effect Of Memantine And Bacopa Monnieri On Lps-Induced Shsy5y Cells Via Amyloidosis, Anti-Inflammatory And Intrinsic Apoptotic Pathways, Archi Anupam Thakor

Selected Full-Text Master Theses 2021-

Background:

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by the extracellular accumulation of Amyloid-β (Aβ) plaques, causing neurotoxicity and leading to neurodegeneration. Amyloid precursor protein (APP) is processed into various Aβ isoforms. It has been shown to contribute to mitochondrial dysfunction and oxidative stress, activating mitochondrial apoptotic pathways and pro-inflammatory factors and leading to neuronal cell death. Memantine (MN) and Bacopa Monnieri (BM) are postulated to have neuroprotective effects, most likely via anti-amyloidogenic and anti-apoptotic mechanisms. The in vitro models suggest a potential for further development of biologically based adjuvant therapeutics for neurodegenerative diseases. However, more precise identification …

The Combination Of Cucurbitacin B And Evodiamine Induces Apoptosis And Inhibits Cell Propagation In Glioma Cells, Vrutti Vikasbhai Mehta

Selected Full-Text Master Theses 2021-

Background

Glioblastoma Multiform (GBM) is a lethal brain tumor. Despite aggressive treatment, the median survival time is 6 to 18 months. These malignant astrocytic tumors exhibit a high proliferation rate and acquire resistance against many existing therapeutic regimens. Temozolomide is a first line chemotherapeutic treatment prescribed along with surgery and radiation but due to the high resistance to the drug and a low patient survival rate, new drugs and drug combinations must continue to be investigated and developed. GBM cells like any cancer cells avoid differentiation and apoptosis. Thus, the induction of differentiation and apoptosis in glioblastoma cells may be …

Articles

As the severe acute respiratory syndrome coronavirus-2 pandemic has proceeded, ventilation has been recognized increasingly as an important tool in infection control. Many hospitals in Ireland and the UK do not have mechanical ventilation and depend on natural ventilation. The effectiveness of natural ventilation varies with atmospheric conditions and building design. In a challenge test of a legacy design ward, this study showed that portable air filtration significantly increased the clearance of pollutant aerosols of respirable size compared with natural ventilation, and reduced spatial variation in particle persistence. A combination of natural ventilation and portable air filtration is significantly more …

Elafibranor Modulates Ileal Macrophage Polarization To Restore Intestinal Integrity In Nash: Potential Crosstalk Between Ileal Il-10/Stat3 And Hepatic Tlr4/Nf-Κb Axes, Andrew Hakeem, Mohamed M. Kamal, Rasha A. Radwan, Basma A. Abdelrahman, Olfat A. Hammam, Mohey M. Elmazar, Aiman S. El-Khatib, Yasmeen M. Attia

Pharmacy

Experimental and clinical evidence implicate disrupted gut barrier integrity in provoking innate immune responses, specifically macrophages, towards the progression of non-alcoholic steatohepatitis (NASH). Peroxisome proliferator-activated receptors (PPARs), a subset of the nuclear receptor superfamily, act to fine-tune several metabolic and inflammatory processes implicated in NASH. As such, the current study was carried out to decipher the potential role of dual PPAR α/δ activation using elafibranor (ELA) on ileal macrophage polarization (MP) and its likely impact on the liver in a NASH setting. To achieve this aim, an in vitro NASH model using fat-laden HepG2 cells was first used to validate …

Gender Differences In Administration Of Tpa In Treatment Of Ischemic Stroke, Christina Annerino

CURE Proceedings

As medicine and pharmacology advance through the years, new life-saving treatments are studied or discovered every day, and a medical emergency is no longer a death sentence. Even with conditions as serious as ischemic stroke, there is hope for survival and rehabilitation with the ‘clot-busting’ drug, tissue plasminogen activator, colloquially known as ‘tPA’. tPA is a thrombolytic agent, a substance that acts on fibrin in clots to dissolve them so they can no longer cause ischemia in blood vessels that results in a stroke. (Vega, 2022). tPA is an extremely effective treatment for ischemic stroke, demonstrated in 2013 by a …

Chronic Anemia Revealing An Idiopathic Watermelon Stomach: Case Report, Hanane Delsa, Imane Rahmouni, Yassamin Benhayoun Sadafyine, Fatima Belabbes, Anass Nadi, Fedoua Rouibaa

Health Sciences

Watermelon stomach, also known as gastric antral vascular ectasia (GAVE) syndrome, is a rare entity. Patients often present with profound unexplained anemia with or without bleeding externalization. We made the diagnosis during a digestive endoscopy for an etiological assessment of this anemia. Endoscopically, antral erythematous lesions in stripes with a punctate appearance, sometimes hemorrhagic, may suggest a watermelon stomach. The pathophysiology of the watermelon stomach remains complex and unclear. Although several pathologies remain implicated, sometimes, it can be idiopathic. The effectiveness of numerous treatments has been evaluated with relatively satisfactory results. This is a rare case of an idiopathic watermelon …

Right Treatment Wrong Time: Immunotherapy Administration Post-Radiotherapy Decreases Tumor Burden In A Preclinical Model Of Brain Metastasis, Kathryn Elizabeth Blethen

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation (a) provided an in-depth literature review of methods to modulate the blood-brain and blood-tumor barriers to increase drug delivery and efficacy in brain metastases, (b) evaluated the effects of whole-brain radiation therapy on the blood-brain barrier in immunocompetent and immunocompromised mouse models and proposed a mechanism by which the immune response to radiation disrupts the blood-brain barrier, and (c) developed a syngeneic lung cancer brain metastasis model to determine the impact of coordinated immunotherapy administration with radiotherapy. The blood-brain barrier is an impediment to drug delivery to the brain. The inherent leakiness of the blood-tumor barrier does not …

Long-Term Prescription Opioid Use, Cancer Stage, And Economic Burden Among Older Cancer Survivors With Non-Cancer Chronic Pain Conditions, Rudi Safarudin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Opioids are commonly prescribed to treat pain conditions, which are highly prevalent among older adults (≥65 years). Recent evidence shows that opioids may have carcinogenic effects through immunosuppression and free-radical pathways, which could promote cancer growth. Two population-based studies have reported an association of opioid use with incident cancer. Many individuals with non-cancer chronic pain conditions (NCPCs) may use opioids for a long term. However, the association of long-term prescription opioid (LPO) use with cancer stage at diagnosis is still unknown. Furthermore, evidence suggests that individuals with cancer and pre-existing NCPCs may persistently use opioids, even in the absence of …

Identifying Unexpected Inflammation Resulting From Drug-Drug Interactions, Keegan Jolly

All Master's Theses

Adverse drug events result in nearly 1.3 million emergency room visits per year in the United States of America. As much as 30% of these adverse events are a result of drug-drug interactions (DDI’s). There is a gap in knowledge concerning these DDI outcomes especially when it comes to inflammation. Inflammation is linked to a variety of chronic health conditions and non-infectious diseases such as cancer. Purpose: The goal of this study was to examine how many active drug ingredients from FDA’s Adverse Event Reporting System (FAERS), when combined (in groups of two or more), elicit an inflammatory response …

Polycationic Colicin N Inhibits Metastatic Activity In Human Lung Cancer Cells Through Suppression On Epithelial To Mesenchymal Transition, Lwin Lwin Aye

Chulalongkorn University Theses and Dissertations (Chula ETD)

Colicins are bacterial toxins, produced by E. coli under stressed conditions to kill other related strains of bacteria. Among other bacteriocins, colicin N is pore-forming bacteriocin which has cytotoxic activity on human lung cancer H460 cells. Polycationic (supercharged) colicin N (CoIN+12) is structurally engineered colicin N with more positive charges, on receptor binding domain of which, aspartic and glutamic acids were replaced by six lysine residues. It has been reported that polycationic colicin N has higher cytotoxic activity in human lung cancer cells. However, anti-metastatic effect of polycationic colicin N on human lung cancer cells has not been investigated. In …

Identification Of Active Region Of Colicin N Translocating Domain Involved In Its Antibacterial Activity, Wanassanan Lampromkaew

Chulalongkorn University Theses and Dissertations (Chula ETD)

Colicins are bacteriocins produced by Escherichia coli (E. coli) and toxified themselves. In general, colicins comprise three domains, including the N-terminal domain or translocation (T) domain, the Receptor binding (R) domain, and the Cytotoxic (C) domain. The combination of these domains produces different types and activities of colicin. Colicin N is the smallest colicin and functioned in pore-formation by the C-domain on the E. coli membrane. The antimicrobial activity is regulated by the specific binding between OmpF and TolA (as receptor and translocator) at region OBS (OmpF binding site) and TABs (TolA binding site), respectively. They are then inserting the …

Α-Glucosidase Inhibitors From Rhynchostylis Retusa, Winartiana -

Chulalongkorn University Theses and Dissertations (Chula ETD)

α-Glucosidase inhibitors are a group of anti-diabetic drugs that can help control blood sugar levels by hindering the breakdown of oligosaccharides and disaccharides into monosaccharides such as glucose, thus preventing intestinal absorption. Recent studies have shown that several plants in the Orchidaceae family produce secondary metabolites with α-glucosidase inhibitory activity. Rhynchostylis retusa, an orchid traditionally used for treating various diseases such as asthma, diabetes, and obesity, was investigated. The methanol extract of R. retusa showed significant inhibitory activity against the enzyme α-glucosidase, with 85.71% inhibition at a concentration of 100 µg/ml.
