Both 3,3,3-trifluoropropene (TFP) and cis-1,2,3,3,3- pentafluoropropene (PFP) are also utilized as propellants and refrigerants.Measurements were carried out with remote access to the CRF-PEPICO (combustion reactions followed …


The Combinatory Effects Of Pediatric Obesity And Ontogeny On Monocarboxylate Transporter Expression In Tissues Of Drug Disposition, Michael Ng Jan 2022

The Combinatory Effects Of Pediatric Obesity And Ontogeny On Monocarboxylate Transporter Expression In Tissues Of Drug Disposition, Michael Ng

University of the Pacific Theses and Dissertations

Proton-coupled and sodium-dependent monocarboxylate transporters are encoded by the SLC16A and SLC5A gene family of solute carriers, and are responsible for the transport of essential nutrients such as L-lactate, pyruvate, and ketone bodies. Basigin, or CD147, acts as an ancillary protein for MCT1 and MCT4, and is involved in membrane surface expression of transporters. MCT's are also involved in the shuttling of monocarboxylic xenobiotics across cell membranes, including the drugs valproate and gamma hydroxybutyrate. MCT’s are also important for normal mammalian development, particularly during embryogenesis and early neonatal life. Previous studies have shown that ketogenic diets increase MCT expression in …


Expression Of Mouse Full-Length Aryl Hydrocarbon Receptor And Human Aryl Hydrocarbon Receptor Ligand Binding Domain In Pichia Pastoris, Yiyuan Wang Jan 2022

Expression Of Mouse Full-Length Aryl Hydrocarbon Receptor And Human Aryl Hydrocarbon Receptor Ligand Binding Domain In Pichia Pastoris, Yiyuan Wang

University of the Pacific Theses and Dissertations

Aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that regulates biological responses to planar aromatic hydrocarbon. AHR activates gene transcription by binding to its corresponding enhancer with its partner-aryl hydrocarbon receptor nuclear translocator (ARNT). In addition, this receptor has been shown to regulate xenobiotic-metabolizing enzymes such as cytochrome P450. AHR exists widely in body tissues and affects bioactivation of carcinogenic compounds, T cell differentiation, fatty acid synthesis, cell proliferation, hematopoietic stem cell differentiation, respiratory reactivity, and insulin sensitivity. Although the precise mechanism illustrating the endogenous AHR function remains unclear, there has been intense interest in exploring AHR as a …

The purpose of this thesis is to determine what effects draft order, monetary earnings, and Tommy John Surgery (TJS) have on the perceived value of a pitcher in Major League Baseball (MLB). For the context of this thesis, value will be defined as a player's ability to contribute to their team's wins in a positive manner. TJS has become synonymous with MLB and baseball as a sport, and many are either skeptical of its effects or over-assuming of its benefits. The three aforementioned areas of concerns were used to structure the thesis, as each dependent outcome is analyzed in a …


Thermodynamic Mechanisms Of Helix Stabilization In A Model Peptide And Protein, Ryan Murray Jan 2022

Thermodynamic Mechanisms Of Helix Stabilization In A Model Peptide And Protein, Ryan Murray

University of the Pacific Theses and Dissertations

Biologics are large, complex therapeutic agents generally produced from living organisms. One group of biologics is peptide/protein based. Biological agents offer unique advantages over traditional therapeutics including longer half-lives, higher specificity, greater efficacy, and reduced off-target effects. However, protein/peptide based drugs suffer from both delivery and stability issues. The higher order of protein structures (secondary, tertiary, etc.) derive ~80% of their conformational stability from paltry hydrophobic effects, with net stabilization of 5-15 kcal/mole observed for many proteins. Loss of conformational stability can lead to increased aggregation, precipitation, and degradation; and reduced activity and side effects. To increase stability and improve …

The Interrelationship Between Treatment, Ethnicity, And Structured Exercise In Clinical Populations, Amanda M. F. Lopez

University of the Pacific Theses and Dissertations

Cancer is the second leading cause of death, with about approximately 1.9 million Americans being diagnosed each year. Yet, it has high survival rates with the help of advancing treatments like radiation therapy. Cancer patients and survivors are contingent on experiencing a decline in physical functioning, quality of life, and physiological parameters. Treatment is effective and can prolong life expectancy but can be deleterious to a patient’s health. Parallel with cancer's impact on Americans is cardiovascular disease. Cardiovascular disease is responsible for 1 in 4 deaths. The development of cardiovascular disease is not spread accordantly among all ethnicities. Hispanics are …


Optimization Of The Structure Of Ttr Ligands For Half-Life Extension (Tlhe), Guanming Jiang Jan 2022

Optimization Of The Structure Of Ttr Ligands For Half-Life Extension (Tlhe), Guanming Jiang

University of the Pacific Theses and Dissertations

Many potential therapeutic agents face challenges for their clinical development due to short circulation half-life. As a result, prolonging the half-life of therapeutic drugs in circulation while preserving their hydrophilicity and small size will be a key step toward more effective and safe pharmacological molecules. Our lab developed a new approach for enhancing the safety and efficacy of therapeutic agents. By endowing therapeutic agents with a hydrophilic small molecule (a derivative of the clinical candidate, AG10) which reversibly binds to the serum protein transthyretin (TTR), the half-life of the therapeutic agent should be extended by binding to the TTR in …

University of the Pacific Theses and Dissertations

Cyclin-dependent kinases (CDKs) and cyclins (Cyclins) are the core molecules in the regulation mechanism of the entire cell cycle. Cell cycle dysregulation is a common feature of human cancers, and inhibitors of cyclin-dependent kinases (CDKs) play a crucial role in cell cycle control and are one of the most promising areas of cancer therapy. We aspired to use our cyclin-dependent kinase 8 (CDK8) inhibitor, Q-12, as a probe for biomarker discovery for CDK8 inhibitor sensitive tumor types. Q-12 shows potent inhibition of cell viability and induction of apoptosis process in some triple-negative breast cancer (TNBC) and colorectal cancer cell lines …

Peripherally Restricted Opioid Conjugates And Its Use As Pharmacological Probes And Potential Therapeutics, Md Tariqul Haque Tuhin

University of the Pacific Theses and Dissertations

Opioid-induced constipation (OIC) is one of the major adverse effects of opioid analgesics used by millions of patients each year. While progress has been made, there remains a significant unmet medical need in the treatment of OIC. Major gaps remain in our understanding of the role of the gastrointestinal tract and central nervous system (CNS) in precipitating OIC. For the last four decades, numerous investigations to study the sites of action of opioid analgesics have utilized peripherally acting mu-opioid receptor antagonists (PAMORAs), which have been incorrectly believed to have limited penetration across the blood-brain barrier (BBB). Several preclinical and clinical …

University of the Pacific Theses and Dissertations

This project describes the development of a new antitumor therapeutic platform that combines the benefits of small-molecule drug conjugates (SMDCs) and antibody drug conjugates (ADCs). Valine-citrulline (VCit) dipeptide linkers are popular cathepsin B cleavable ADC linkers. Due to its instability in mouse serum, translating efficacy data from mouse to human is more difficult. It has been reported that replacing the VCit linker with glutamic acid-valine-citrulline (EVCit) improves ADC stability in mouse serum. The effect of the EVCit linker on the stability of SMDCs has not been reported so far. In a xenograft mouse model of prostate cancer, we found that …
