Nicotine And Methylphenidate Chornic Exposure On Adult Cannabinoid Receptor Agonist (Cp 55,940) Place Conditioning In Male Rats, Christopher P. Plant

Electronic Theses, Projects, and Dissertations

A problematic connection has been reported between those who use nicotine related products alone or in combination with ADHD medications, like methylphenidate (MPH), in late childhood or early adolescence and the increased likelihood of later marijuana abuse in adulthood. Pre-clinical studies have found that the use of nicotine during the early adolescence period produces enduring changes to the endocannabinoid system in the brain. Since CB agonists, like marijuana, exert their effect through the eCB system, it is possible that early nicotine use may alter the rewarding nature of CB agonists in adulthood. In addition, MPH has also been shown to …

Goodbye To All That Again, Charles Bradley Von Nordheim

Electronic Theses, Projects, and Dissertations

Goodbye to All That Again concerns the odyssey of an Iraq War veteran who must complete his journey past desert combat and academic strife in order to reclaim his heroic identity. The novel uses a fragmented storytelling mode that offers readers thirteen years of the protagonist’s timeline in a nonlinear sequence. Through this technique, the novel evokes the cognitive disassociation experienced by individuals who suffer Post Traumatic Stress and echoes the postmodern practices employed by American military novelists such as Joseph Heller and Tim O’Brien for the last sixty years.

GOODBYE TO ALL THAT AGAIN seeks to intervene in the …

Foster Parenting...Why Not?, Michelle Y. Marley

Electronic Theses, Projects, and Dissertations

Every day, children are removed from their homes of origin by Children & Family Services and placed into foster care. When the county foster homes become full, private foster family agencies are relied upon to take in the overflow. For a variety of reasons, private agencies are finding it increasingly difficult to recruit and retain sufficient numbers of foster parents to house all of these children. This is a pressing problem in the social work field as, without proper placement options, many children will simply fall through the cracks in the system. The purpose of this research was to explore …

Childhood Sexual Assault, Schemas, And Revictimization: The Role Of Early Maladaptive Schemas On Revictimization, Lisa S. Motley

Electronic Theses, Projects, and Dissertations

Childhood sexual assault (CSA) refers to a sexual act that is imposed on a child or adolescent who lacks the emotional capacity, maturity, and cognitive development to understand what they are engaging in, and is incapable or unwilling to give consent. Many individuals who experience CSA also experience adult sexual assault, such as rape. To date, there is limited research that has examined early maladaptive schemas (EMS) and CSA, and no research that examines the relationship between CSA, EMS, and revictimization. The present study examined EMS as mediators of revictimization and mental health outcomes (i.e., depression and PTSD) among 263 …

Narva, Blair D. Siegfried

Department of Entomology: Faculty Publications

The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, is an important maize pest throughout most of the U.S. Corn Belt. Bacillus thuringiensis (Bt) insecticidal proteins including modified Cry3Aa and Cry34/35Ab1 have been expressed in transgenic maize to protect against WCR feeding damage. To date, there is limited information regarding the WCR midgut target sites for these proteins. In this study, we examined whether a cadherin-like gene from Diabrotica virgifera virgifera (DvvCad; Gen-Bank accession # EF531715) associated with WCR larval midgut tissue is necessary for Cry3Aa or Cry34/ 35Ab1 toxicity. Experiments were designed to examine the sensitivity of WCR to …

Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay

Loma Linda University Electronic Theses, Dissertations & Projects

Touted among the major achievements in the diagnosis and management of Prostate cancer (PCa) in the past few decades has been, the dramatic decline of men with advanced/metastatic PCa at diagnosis coupled with a significant improvement ( >90%) in the five and ten year survival rates of the disease. Non-palpable PCa (potentially clinically treatable disease) now accounts for 70-80% of all newly diagnosed cases of PCa. Preceding these changes by about a decade was the introduction of Prostatic Specific Antigen (PSA) into clinical practice; first as biomarker for monitoring response to therapy and subsequently as a complementary screening tool. It …

Mechanism Of Chimeric Vaccine Mediated Immune Suppression Of Human Dendritic Cells, Jacques Christian Mbongue

Loma Linda University Electronic Theses, Dissertations & Projects

Type 1 diabetes mellitus is a chronic inflammatory disease in which insulin producing β-cells of the pancreatic islets are killed by autoreactive cells of the immune system in response to a loss of tolerance. Dendritic cells (DC) interact predominantly with naïve T cells to regulate the delicate balance between immunity and tolerance required to maintain immunological homeostasis. In this dissertation, immature human dendritic cells (iDC) were inoculated with a chimeric fusion protein vaccine containing the pancreatic β-cell auto-antigen proinsulin linked to a mucosal adjuvant the cholera toxin B subunit (CTB-INS). Proteomic analysis of vaccine inoculated DCs revealed strong up-regulation of …

The Role Of Collagen Interacting Proteins In The Pathogenesis Of Filifactor Alocis, Ozioma Salomey Chioma

Loma Linda University Electronic Theses, Dissertations & Projects

Filifactor alocis is a Gram-positive, asaccharolytic; obligate anaerobe that has emerged as a potential periodontal pathogen due to its presence in high numbers in patients who have periodontal disease and least detection in healthy individuals (Kumar et al., 2003, Kumar et al., 2006, Wade, 2011). There is compelling evidence in the literature that demonstrates that F. alocis has virulence properties that may play an important role in infection-induced periodontitis (Abusleme et al., 2013, Griffen et al., 2012, Hutter et al., 2003, Khader et al., 2006, Siqueira and Rocas, 2003, Siqueira et al., 2009). However, there is a gap in our …

Defining the role of cytokines in promoting human B cell development is important for understanding B cell leukemia and for developing strategies to restore B cell production that is lost during some therapies. The purpose of this study was to investigate the roles of the IL-7R ligands, thymic stromal lymphopoietin (TSLP) and IL- 7, in the early stages of normal postnatal and adult human B cell development. Using novel in vitro and in vivo model systems, we show that TSLP and IL-7 are able to expand B cell precursors individually and in combination from CB hematopoietic stem cells. In this …

Effects Of Bisphenol-A And Styrene On Fertilization And Development Of The Purple Sea Urchin (Strongylocentrotus Purpuratus), Nicole C. Uibel, Nikki L. Adams, Jennifer Carroll, Sean Lema

Master's Theses

Plastic waste and debris have greatly increased in the marine environment during the past 50 years. Not only do these plastics entangle and get ingested by marine mammals, turtles, and sea birds, but they also leach chemicals, such as bisphenol-A (BPA) and styrene into the aquatic environment. While some of these chemicals are known to be toxic, few studies have examined their effects on broadcast spawning marine invertebrates, specifically at environmentally relevant concentrations. Purple sea urchins, Strongylocentrotus purpuratus, from the central coast of California, were utilized to examine effects of BPA and styrene on fertilization success and early development of …

Genes Encoding Flower- And Root-Specific Functions Are More Resistant To Fractionation Than Globally Expressed Genes In Brassica Rapa, Naiyerah F. Kolkailah

Master's Theses

Like many angiosperms, Brassica rapa underwent several rounds of whole genome duplication during its evolutionary history. Brassica rapa is particularly valuable for studying genome evolution because it also experienced whole genome triplication shortly after it diverged from the common ancestor it shares with Arabidopsis thaliana about 17-20 million years ago. While many B. rapa genes appear resistant to paralog retention, close to 50% of B. rapa genes have retained multiple, paralogous loci for millions of years and appear to be multi-copy tolerant. Based on previous studies, gene function may contribute to the selective pressure driving certain genes back to singleton …

The Effects Of Quorum Sensing And Temperature On The Soluble Proteome Of Vibrio Salmonicida, Christopher L. Massey

Master's Theses

Vibrio salmonicida causes cold-water vibriosis in salmon populations around the world and causes financial damage to fisheries designed to farm these salmon. Very little is known about the physiology of how V. salmonicida causes disease and measures to contain vibriosis are restricted to either vaccinating individual fish against disease or administering antibiotics when an outbreak is detected. These procedures are costly and increase the risk for selection of antibiotic-resistant V. salmonicida strains. A recent reoccurrence of outbreaks in Norwegian fisheries provided incentive to better understand the virulence mechanisms of V. salmonicida. In this thesis, a proteomic approach was used to …

An Ergonomics Analysis Of Redundancy Effect In Touch Screen Design For The Aged Population, Sarah Riesenberg

Master's Theses

Touch screen technology is rapidly increasing, and at the same time there is a shifting, aging population. As the percentage of the population over the age of 65 increases, adults of the age group are adopting smartphones and tablets more now than ever before. Although older adults are adopting touch screen devices, they face many challenges when interacting with said devices, such as not knowing how to navigate between pages, not knowing where to click for an action to occur, and the touch screen interface is often too sensitive or the buttons are not big enough. Furthermore, the challenges of …

Skewer: Sentiment Knowledge Extraction With Entity Recognition, Christopher James Wu

Master's Theses

The California state legislature introduces approximately 5,000 new bills each legislative session. While the legislative hearings are recorded on video, the recordings are not easily accessible to the public. The lack of official transcripts or summaries also increases the effort required to gain meaningful insight from those recordings. Therefore, the news media and the general population are largely oblivious to what transpires during legislative sessions.

Digital Democracy, a project started by the Cal Poly Institute for Advanced Technology and Public Policy, is an online platform created to bring transparency to the California legislature. It features a searchable database of state …

Rearing Temperature Affects The Expression Of Proteins In The Adhesive Of The Striped Acorn Barnacle, Balanus Amphitrite, Melissa J. Daugherty

Master's Theses

Barnacles are dominant hard–fouling organisms in marine waters. They attach to substrates by secreting a complex proteinaceous adhesive. Understanding the chemical composition of this multi–protein underwater adhesive and how it is affected by environmental variables, such as oceanic temperatures, is critical for developing nontoxic solutions to control biofouling. Previous experiments in our lab revealed an inverse relationship between critical removal stress (CRS) and temperatures at which barnacles were reared. Further investigations showed that this correlation is not attributed to differences in physical properties such as barnacle size or short–term changes in the viscosity of adhesive. Therefore, the observed effects may …
