Baylisascaris Procyonis Prevalence And Impact In Raccoon (Procyon Lotor) Populations, Matthew Ingle

Loma Linda University Electronic Theses, Dissertations & Projects

Baylisascaris procyonis is a nematode parasite that infects the small intestines of raccoons (Procyon lotor). Raccoons are the definitive host for this parasite, which can have both an indirect and direct life cycle. In intermediate hosts, the parasite causes serious pathology resulting from larvae migrating through host tissue to the brain. Infection via exposure to B. procyonis eggs is fatal in over 90 vertebrate species that serve as intermediate hosts, including humans. The zoonotic potential of B. procyonis makes understanding factors that impact prevalence and pathology in raccoons important for management strategies. Alimentary canals from 226 raccoons trapped in nine …

Intergenerational Congruence In Chinese American Young Adults, Kimberly Doe

Loma Linda University Electronic Theses, Dissertations & Projects

Chinese American families are often underrepresented within the family therapy literature. This grounded theory study used a symbolic interaction framework to understand how second generation young adults locate themselves within the larger cultural context to construct an individual ideology. Semi-structured interviews were conducted with Chinese American young adults between the ages of 18-24. Family and cultural experiences influences how young adults develop and transition from childhood to adolescence to young adulthood. This study suggests the importance for family therapists to identify Chinese American young adults’ experiences and their development to understand how multiple factors impact their construction of “I”.

Measurements of loading and unloading forces were recorded in …

Effects Of Cigarette Smoking On Neurocognitive Performance In Dementia Patients, Christina Mannino

Loma Linda University Electronic Theses, Dissertations & Projects

Dementia has become a serious problem worldwide due to the rapidly increasing incidence rate and the lack of effective treatments that cure or slow disease progression, and thus. prevention is crucial. Some studies suggests that cigarette smoking may increase the risk of developing dementia, but others suggest that smoking may have a neuroprotective effect. To clarify our understanding of the relationship between cigarette smoking and dementia, this study examined the effects of smoking on multiple cognitive domains via secondary data analysis of a sample consisting of 54% female subjects with an average age of 58±13 years. Measures of executive function, …

Role Of Astrocyte Network In Edema After Juvenile Traumatic Brain Injury, Andrew Minoru Fukuda

Loma Linda University Electronic Theses, Dissertations & Projects

Juvenile traumatic brain injury (jTBI) is the leading cause of death and disability in young children and adolescents. Despite its lasting detrimental effects on the developing brain, no pharmacological treatment exists. One of the pathological hallmarks of jTBI is edema. Astrocytes play a key role in the edema process, and have been hypothesized that numerous astrocyte networks allow communication and propagation of edema and secondary injury spread. Two key astrocyte proteins are hypothesized to have a central role in the edema process: Aquaporin 4 (AQP4) and Connexin 43 (Cx43). AQP4 is expressed extensively in astrocyte endfeet, which surrounds the blood …

Cbct And Cephalometric Analysis Of The Tmj Complex After Treatment Using A Mara Appliance, Melissa Danette Shotell

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: The mandibular anterior repositioning appliance (MARATM) is a fixed appliance intended for the correction of class II malocclusion. Many advocate the use of the MARA appliance to minimize patient non-compliance with treatment; however, little information is known as to the skeletal changes in the temporomandibular complex. The purpose of this study is to investigate the changes in the temporomandibular complex using both cephalometric and cone beam computerized tomography.

Materials and Methods: The initial and final treatment cone beam computerized tomography (CBCT) scans of 5 patients treated with the MARA appliance were collected from the Loma Linda University Orthodontics Clinic. …

Changes In Emotion Drive Perceptual Level Shifts: Global Vs. Local Processing, Seda Terzyan

Loma Linda University Electronic Theses, Dissertations & Projects

Different emotional states have been implicated in bringing about specific changes in attention, with positive emotions globalizing attention and negative emotions localizing attention (Fredrickson, 2004). Biases in attentional processes have been associated with the development and maintenance of emotional disorders, anxiety being the most common. Previous studies have shown that anxious individuals present with a bias toward negative information and more readily employ localized attentional processes (Macleod, 2002). This finding demonstrated a link between perceptual levels of attention with higher order conceptual attention, which in turn influences emotional states. Many researchers have explored this relationship, including Fredrickson (2004), who developed …

Minority Parents' Narratives Of Living With Their Child With An Autism Spectrum Disorder, Monique Willis

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies addressing the impact of autism spectrum disorder (ASD) on the family focus largely on the Caucasian population (Cassidy, McConkey, Truesdale-Kennedy, & Slevin, 2008; Hebert & Koulouglioti, 2010; N. Johnson, Frenn, Feetham, & Simpson, 2011; Myers, Mackintosh, & Goin-Kochel, 2009; Rao & Beidel, 2009). There is a dearth of research examining the impact of ASD on family dynamics in marginal groups. This study attempts to add to the sparse literature and to increase understanding of the specific experiences of minority parents of children with ASD. Family systems theory, family systems-illness model, and social constructivism frameworks inform this study and …

The Effects Of Appearance-Based Reality Shows On Body Image, Amanda F. Suplee

Loma Linda University Electronic Theses, Dissertations & Projects

Media seems to play the largest role in transmitting messages regarding societal standards of attractiveness; especially in reinforcing the thin ideal for females. There is strong evidence indicating that females who are more likely to make appearance comparisons with thin images in the media often experience negative outcomes. Research has shown that increased exposure to thin images in the media is associated with higher body dissatisfaction and eating disorder features. A form of media that has been given little research attention is reality television, specifically appearance-based reality television. The current study examined the effects of viewership of appearance-based reality television …

Effects Of Proton Radiation On Behavior In A Mouse Model Of Alzheimer’S Disease, John A. Bellone

Loma Linda University Electronic Theses, Dissertations & Projects

Astronauts venturing outside Earth’s magnetosphere risk exposure to charged particle radiation that has been shown to cause neurological deficits in rodents via oxidative stress, neuroinflammation, altered neurogenesis, and synaptic changes. Since these responses are similar to those observed in age-related neurodegenerative diseases, we hypothesized that individuals with a propensity toward developing Alzheimer’s disease (AD) would be more adversely affected by such exposure. To test this hypothesis, we exposed young double transgenic APP/PSEN1 mice (a commercially available strain engineered to develop AD-like neuropathology) and their wild-type (non-transgenic) counterparts to low doses of 150 MeV proton particle radiation and assessed the effects …

Development, Characterization, And Optimization Of Process For Minimal Functional Barrier And Channel Width In Nitrocellulose Paper Microfluidic Diagnostic Platforms, Ryan Daniel Silva

Biomedical Engineering

A central goal of diagnostic microfluidics is to reduce the cost of diagnostic medicine by reducing the equipment and reagents needed to perform diagnostic tests. The literature has demonstrated that a wax printer can be used to pattern nitrocellulose paper with hydrophobic barriers to direct a sample in a defined reaction path, eliminating the need for external pumps and controllers. However, manufacturing methods for minimizing sample volume (and thus reagent volume) in a paper-diagnostic chip have not been well defined. In this work, we experimentally determine manufacturing processes for creating functional features of minimal size—effectively reducing the sample size and …

Circulating Angiogenic Cell Population Responses To 10 Days Of Reduced Physical Activity, Gayatri Guhanarayan, Julianne Jablonski, Sarah Witkowski

Exercise and Sport Studies: Faculty Publications

Circulating angiogenic cells (CACs) are a diverse group that have been identified as predictors of cardiovascular health and are inversely proportional to cardiovascular disease (CVD) outcomes. Inactivity is a growing concern in industrialized nations and is an independent risk factor for CVD. There is limited evidence regarding the impact of reduced physical activity (rPA) on different CAC populations. The purpose of this study was to evaluate the effect of objectively monitored rPA with maintained energy balance on two CAC populations (CFU and CD34+cells), intracellular nitric oxide (NOi), and genes related to NO production in active, healthy men. Participants (age 25 …

Música De Las Grullas: Una Historia Natural De Las Grullas De América, Paul A, Johnsgard, Enrique H. Weir, Karine Gil-Weir

Zea E-Books Collection

En un sábado mágico de marzo, maneje con un estudiante de postgrado hasta el valle central del Platte, al oeste de Grand Island, tanto para ver la migración primaveral de aves acuáticas como la de las grullas grises. Tal vez fue una suerte que yo no estuviera preparado emocionalmente para ver como innumerables grullas salpicaban el cielo de horizonte a horizonte, o girando grácilmente sus cabezas como si estuvieran atrapados en algún torbellino de ultra cámara lenta, su vibrato produce una cadencia descendente como la música de un coro aviar angelical. Desde los días de mi infancia, cuando, por primera …

Queering Masturbation In Lorde's Life And Writing, Eric Sipyinyu Njeng

CLCWeb: Comparative Literature and Culture

In his article "Queering Masturbation in Lorde's Life and Writing" Eric Sipyinyu Njeng discusses masturbation in Audre Lorde's life and works to signal an important aspect of her oeuvre often neglected in scholarship. Lorde stands out among prominent queer queens by demonstrating theory corporeally thereby going beyond mere theory and positing her body as a space of complex sexual passions. When Judith Butler speaks of gender as performative rather than embodied, Lorde theorizes and foregrounds this in her works and self and celebrates a sexual matrix that ranges from heterosexuality to homosexuality to auto-sexuality. Lorde places masturbation between the binary …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Introduction: Pre-exposure prophylaxis (PrEP) may be an important safer conception strategy for HIV-1–uninfected women with HIV-1–infected partners. Understanding medication adherence in this population may inform whether PrEP is a feasible safer conception strategy.

Methods: We evaluated predictors of pregnancy and adherence to study medication among HIV-1–uninfected women enrolled in a randomized placebo-controlled trial of PrEP among African HIV-1– serodiscordant couples. Participants were counseled on HIV-1 risk reduction, contraception, and adherence and tested for pregnancy at monthly study visits. Pill counts of dispensed drug were performed and, at a subset of visits, plasma was collected to measure active drug concentration.

Results: …
