Effects Of Extended Intervention Conditions On Levels Of Physical Activity Exhibited By Young Children, Ingunn Kristjansdottir Oveny

University of the Pacific Theses and Dissertations

Physical activity is an important health-related behavior, and The Centers for Disease Control and Prevention (CDC) recommends that children engage in at least 60 minutes of moderate-to-vigorous-physical activity (MVPA) daily (CDC, 2015). However, worldwide, many children do not reach those requirements and health problems associated with physical inactivity are becoming more prevalent (CDC, 2015; World Health Organization [WHO], 2016). Recently, a few studies have conducted an intervention analysis to evaluate implications for function-based interventions to increase physical activity (Larson, Normand, Morley, & Miller, 2014; Zerger, Normand, Boga, & Patel, 2016). However, intervention analyses, indicate an overall decrease in levels of …

Developing X-Ray Spectromicroscopic Techniques To Quantitatively Determine Population Statistics And Individual Particle Composition Of Complex Mixed Aerosols, Matthew Fraund

University of the Pacific Theses and Dissertations

Aerosols are a major source of uncertainty in estimates of anthropogenic effects on global radiative forcing and can pose serious health concerns. While many instrumental techniques capable of analyzing aerosol samples are available, individual-particle spectromicroscopic techniques like the ones presented here are the only ones to offer morphological and compositional measurements together. Studying the composition and mixing state of aerosol populations allowed for important aspects to be uncovered, such as: aerosol source, formation mechanism, hygroscopicity, optical properties, level of aging, and inhalation dangers. Ambient aerosols from the Amazon, both biogenic and anthropogenic, were apportioned based on their individual composition. Recently …

Roaming Transition States And Highly Accurate Thermochemistry: A Pepico Study Of Two Small Combustion Systems, Kyle John Covert

University of the Pacific Theses and Dissertations

Two small combustion systems, methyl hydroperoxide (CH₃OOH) and 2-propanol ((CH₃)₂CHOH), were studied using imaging photoelectron photoion coincidence spectroscopy (iPEPICO), which combines photoelectron spectroscopy and photoionization mass spectrometry to detect coincident photoelectron-photoion pairs. In the photon energy range of 11.4–14.0 eV, energy selected CH₃OOH⁺ ions dissociate into CH₂OOH⁺, HCO⁺, CH₃⁺, and H₃O⁺ ions. The lowest-energy dissociation channel is the formation of the cation of the smallest “QOOH” radical, CH₂OOH⁺. A statistical rate model fitted to the …

Development And Characterization Of Ldv Peptide Targeted Nanocarriers For Paclitaxel Delivery: A Comparative Study Of Micelles, Liposomes And Solid Lipid Nanoparticles, Poonam Dattani

University of the Pacific Theses and Dissertations

Nanocarriers have been established as delivery vehicles to target cancer tumors. However, premature drug leakage is one of the major reasons for inefficient drug delivery of nanocarriers to the tumor. Drug diffusion out of the nanocarriers or destabilization of drug loaded nanocarriers by physiological interactions with blood cells, serum proteins, and cell membranes upon systemic administration contribute to premature drug release. In this study, targeted micelles, liposomes and solid lipid nanoparticles (SLNs) of similar composition were prepared and characterized to compare physicochemical characteristics, in vitro stability, in vitro release rates in release media and in vivo performance. Peptide Amphiphiles (PAs) …

Lipid-Coated Magnesium Phosphate Nanoparticles For Intrapulmonary Protein Delivery In Mice, Mallika Vadlamudi

University of the Pacific Theses and Dissertations

Proteins are a diverse category of biomolecules with great therapeutic potential. Intracellular delivery of proteins can augment the deficient activities of dysfunctional or poorly expressed innate proteins and therefore represents a promising strategy to treat the associated diseases. One major barrier to intracellular protein delivery is the translocation of the protein across the cellular membrane. Endocytosis provides an important pathway for protein nanocarriers to enter cells across the plasma membrane. However, the cargo protein must then promptly escape from the endosomes to avoid degradation in the lysosome and to exert its cellular function.

Previously, we reported a cationic lipid-coated magnesium …

Currently, there is inconclusive evidence with lower volume energy drinks. This study intends to evaluate the effects of the largest commercially available energy drink can (24 ounces) in the United States on cardiovascular parameters compared with placebo arm. A randomized, double-blinded, placebo-controlled, crossover trial was conducted over 2 separate days with a minimum of 6-day wash out period. Healthy volunteers between the age …

Knob-Socket Investigation Of Stability And Specificity In Alpha-Helical Secondary And Quaternary Packing Structure, Taylor Renee Rabara

University of the Pacific Theses and Dissertations

The novel knob-socket (KS) model provides a construct to interpret and analyze the direct contributions of amino acid residues to the stability in α-helical protein structures. Based on residue preferences derived from a set of protein structures, the KS construct characterizes intra- and inter-helical packing into regular patterns of simple motifs. The KS model was used in the de novo design of an α-helical homodimer, KSα1.1. Using site-directed mutagenesis, KSα1.1 point mutants were designed to selectively increase and decrease stability by relating KS propensities with changes to α-helical structure. This study suggests that the sockets from the KS Model can …

Approaches To The Search Of Platinum Anticancer Agents: Derivatizing Current Drugs And Incorporating Hdac Inhibition, Chao Feng

University of the Pacific Theses and Dissertations

Platinum-based anticancer drugs, such as cisplatin, carboplatin, and oxaliplatin, have been approved for clinical use worldwide for decades. Despite their enormous success, their widespread application is hindered by either cross-resistance or toxic side effects, including nephrotoxicity and neurotoxicity. The need to overcome these drawbacks has stimulated the search for new platinum-based drugs.

This dissertation will start with the accidental discovery of cisplatin, followed by an introduction of other platinum-based anticancer agents, including the action mechanism, general structures, and development history. Picoplatin is a newer generation of platinum-based anticancer agent. The bulky 2-methylpyridine as a non-leaving group on picoplatin could reduce …

ASTM D3241 (Standard Test Method for Thermal Oxidation Stability of Aviation Turbine Fuels) measures the thermal oxidative stability of jet fuels under elevated temperature and pressure conditions. When jet fuels fail ASTM D3241, either at the refinery or in the distribution system, there can be supply disruptions and financial losses. Understanding the causes of poor thermal oxidative stability in jet fuels could help prevent or mitigate issues. In order to develop a deeper understanding of the molecular precursors that lead to ASTM D3241 failures, a number of analytical methodologies and data treatment techniques have been developed, applied, and reported here. …

Investigating The Effect Of Rutaecarpine On The Benzo[A]Pyrene-Induced Dna Damage In Vitro, You Li

University of the Pacific Theses and Dissertations

Benzo[a]pyrene (BaP), is one of the most potent mutagens and carcinogens known. It requires metabolic activation through cytochrome P450 (CYP)1A1 to yield the ultimate carcinogenic metabolite, benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide (BPDE). BPDE can bind to DNA and form predominantly covalent (+) trans adducts at the N2 position of guanine causing DNA damage. Rutaecarpine (RTC) is an herbal medicine that has been used to treat several diseases such as headache, hypertension, gastrointestinal disorders, amenorrhea, and anti-inflammation. It has also been reported as a potent inducer of CYP enzymes, including CYP1A1, and CYP1A2. The mechanisms underlying up-regulation of CYP1A1 by RTC is dependent on aryl …

Development Of A New Class Of Ligand-Targeted Chemotherapeutics With Enhanced Safety And Efficacy Profile, Arindom Pal

University of the Pacific Theses and Dissertations

The hydrophobicity of many chemotherapeutic agents usually results in their nonselective passive distribution into healthy cells and organs causing collateral toxicity. Ligand-targeted drugs (LTDs) are a promising class of targeted anticancer agents. The hydrophilicity of the targeting ligands in LTDs limits its nonselective passive tissue distribution and toxicity to healthy cells. In addition, the small size of LTDs allows for better tumor penetration, especially in the case of solid tumors. However, the short circulation half-life of LTDs, due to their hydrophilicity and small size, remains a significant challenge for achieving their full therapeutic potential. Therefore, extending the circulation half-life of …

A Cost Control Model For Inpatient Medications Among Adults With Mental And Behavioral Health Disorders, Huanan Li

University of the Pacific Theses and Dissertations

Pharmaceutical expenditures are an important part of the entire hospital operating budget, and inpatient pharmaceuticals denote one of the highest costs in hospital care. Predictions for medication budgets based on the types of patients have been largely undertaken in medical hospitals and not psychiatric facilities. According to several previous studies, gender, age, diagnosis, comorbidity and length of stay (LOS) affect the general inpatient treatment expenditures. However, whether or not the impact of these factors differs in psychiatric hospitals remains to be investigated. To that end, the current study examines medication costs for mental and behavioral health disorder as well as …

Synthesis And Conformational Studies Of Various Amides, Marcos Beltran-Sanchez

University of the Pacific Theses and Dissertations

In the past, aminocyclohexanol rings have been successfully utilized as pH-triggered molecular switches in various trans-2-aminocyclohexanol derivatives. By changing the groups on the amine nitrogen, these models provided a wide pH range in which a switch can occur. The pH-induced switch of conformation was monitored by 1H-NMR spectroscopy. The models were also incorporated into the bilayer membrane of liposome structures and tested for their ability to disrupt their membrane upon their conformational flip induced by a decrease in pH.

In this work, the amide bond has been studied as a molecular switch and various amide derivatives have been tested for …

Chapter 8: Is The Preemption Clause Of Erisa Unconstitutional?, Andrew Morrison, Elizabeth Mccuskey

Faculty Scholarship

The authors suggest plaintiffs and/or state attorneys general should consider taking Justice Clarence Thomas up on his effective suggestion, in the 2016 Supreme Court case of Gobeille v. Liberty Mutual Insurance, to put before the federal courts the question whether the preemption clause of the Employee Retirement Income Security Act of 1974 (“ERISA”) represented a valid exercise of federal power under the Commerce Clause of the Constitution. ERISA’s exceptionally broad statement of preemption does in fact seem to have unconstitutional reach: It purports to preempt “any and all” state laws that simply “relate to” employee benefits, a formulation without logical …

Big Waiver Under Statutory Sabotage, Elizabeth Mccuskey

Faculty Scholarship

The Affordable Care Act's State Innovation waiver allows federal agencies to suspend the most controversial parts of the statute for states to pursue alternative paths, while keeping the federal funding provided by the statute. This "big waiver" provision has the potential to enable states to pursue transformative health reforms, while preserving the affordability and universal coverage aims of the federal statute. Big waivers like this one carry theoretical promise, which largely depends on the strength of the federal statute's baseline infrastructure. This Essay considers early implementation of the State Innovation waiver as a test for big waiver theory - and …

The Sanctuary Of Prosecutorial Nullification, Zohra Ahmed

Faculty Scholarship

In the aftermath of the 2016 election, the shortcomings of existing sanctuary protections came sharply into focus.¹ Historically, cities enacted sanctuary protections to extricate their law enforcement agencies from activities related to federal immigration enforcement. In sanctuary cities, local government agencies are typically restricted from sharing information with federal immigration authorities or from cooperating in apprehending individuals targeted for removal. ² After the White House issued an Executive Order (EO) in late January 2017, many immigrant rights advocates recognized that external facing policies that proscribed direct cooperation would not suffice. ³ The EO announced that Immigration and Customs Enforcement …
