Expression And Function Of Ca2+-Activated K+ Channels In Uterine Arteries, Ronghui Zhu

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic hypoxia during pregnancy is one of the most common insults to the maternal cardiovascular system and fetal development, and is associated with increased uterine vascular tone and heightened risk of preeclampsia and fetal intrauterine growth restriction (IUGR). The present study tested the hypothesis that calcium-activated potassium (KCa) channels play an essential role in uterine vascular adaptation to pregnancy, which is inhibited by chronic hypoxia during gestation. Uterine arteries (UAs) were isolated from nonpregnant ewes (NPUAs) and near-term pregnant ewes (PUAs) that had been maintained at sea level (~300 m) or exposed to high altitude (3,801 m) for 110 days. …

Sympathetic Nerve Modulation Of Joint Pathology In Adjuvant-Induced Arthritis, Carlo Anthony Wood

Loma Linda University Electronic Theses, Dissertations & Projects

Background: There is increasing data suggesting a net increase in sympathetic tone plays an important role in rheumatoid arthritis. Several studies have reported altered distribution and density of autonomic nerves in patients with rheumatoid arthritis and animal models for the disease. This provides anatomical evidence that supports a neurally-mediated drive in inflammation and joint destruction. Methods: Adult rats were injected with complete Freund’s adjuvant. At 12 days post immunization, animals were randomly placed into a drug treatment group (SH1293, which interacts with - and ß2-ARs), an adjuvant arthritic group, or a control group. These animals were sacrificed at 14, 21, …

Inter-Rater Reliability Of Lumbar Segmental Instability Tests And The Subclassification, Faisal Mohammad Alyazedi

Loma Linda University Electronic Theses, Dissertations & Projects

Objectives: This study investigated the inter-rater reliability of three structural end-range lumbar segmental instability tests with the highest positive Likelihood Ratio against flexion-extension radiographs, and three functional mid-range clinical tests that predict the success of lumbar stabilization exercises in patients with recurrent or chronic low back pain (R/CLBP). It also investigated the reliability of lumbar segmental instability subclassification as: Functional, Structural and Combined Instability. Method: 40 adult with R/CLBP patients (30 men and 10 women), 18 to 80 years of age, underwent repeated measurements of specific clinical tests for structural or functional lumbar segmental instability. Results: Other than the Lack …

Radiosensitization Of Head & Neck Carcinoma Cells By Linifanib, A Receptor Tyrosine Kinase Inhibitor, Heng-Wei Hsu

Loma Linda University Electronic Theses, Dissertations & Projects

Tumor angiogenesis is a hallmark of advanced cancers and promotes invasion and metastasis. Over 90% of head and neck squamous cell carcinomas (HNSCC) express angiogenic factors such as vascular endothelial growth factor (VEGF). Since radiotherapy is one of the most commonly used treatments for HNSCC, it is imperative to identify the interactions between antiangiogenic therapy and radiotherapy, and to develop combination therapy to improve clinical outcome. The mechanisms between antiangiogenic agents and ionizing radiation are complicated and involve many interactions between the vasculature, tumor stroma and tumor cells. The proliferation and metastasis of tumor cells rely on angiogenesis/blood vessel formation. …

Student Healthcare Providers' Illness Narratives: Impact On Family-Focused Care, Lindsey Ann Lawson

Loma Linda University Electronic Theses, Dissertations & Projects

In this study, we interviewed 30 students training for three areas of healthcare: medicine, nursing, and medical family therapy (MedFT). Through grounded theory analysis of these interviews, we looked to understand how these providers connected their own experiences with illness to their clinical work, particularly in including patients’ family members in care. The majority of participants, and especially those in medicine and nursing disciplines, described a tension between their desire to connect with patients and families and their developing definition of professionalism. For others, the impact of students’ personal experiences with illness seemed to provide a different definition of professionalism, …

Caveolins And Njks Influence Brain Endothelial Permeability After Juvenile Tbi, David Olufemi Ajao

Loma Linda University Electronic Theses, Dissertations & Projects

Disruption of blood-brain barrier (BBB) is a key secondary event that exacerbates brain damage following traumatic brain injury (TBI). BBB disruption is particularly damaging to the developing brain – which is highly vulnerable to various stress stimuli, resulting in increased brain swelling, disrupted cerebral blood flow (CBF) autoregulation, long-term disabilities and death following TBI in young demographic. Unsurprisingly, BBB disruption and the resultant cerebral edema have emerged as therapeutic targets in juvenile TBI. It is therefore important to understand the molecular players and mechanisms involved in TBI-induced BBB disruption in the juvenile brain. To this end, the endothelial caveolins and …

Association Of Dietary Intake Patterns With Emotion Regulation, Megan Holt

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Western dietary patterns, characterized by high intakes of trans fatty acids (TFA’s), are associated with numerous preventable chronic diseases. Conversely, a Mediterranean dietary pattern is known to be favorably associated with health. Recent findings suggest a correlation between Mediterranean dietary patterns and positive affect, and an inverse correlation with negative affect. Trans fatty acid intake is also associated with negative affect. Further, affect disturbances are associated with emotion dysregulation. We have yet to understand the association of diet with emotion regulation after taking affect disturbances into consideration. The purpose of this study was to examine effects of Mediterranean diet …

Never Smokers -- Are They More Sensitive To The Respiratory Health Effects Of Ambient Air Pollution?, Zuhair Saleh Natto

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Several studies show an association between ambient particulate matter (PM) and all-cause mortality. The Adventist Health and Smog 1 (AHSMOG-1) study (N=6,338) has previously found associations between ambient air pollution and incident chronic obstructive pulmonary disease (COPD) using the spatial interpolation method from the three nearest fixed monitoring stations to residence and workplace. However, few studies have assessed the risk of death among disease specific subgroups such as those with COPD.

Objectives: The aims of this study were 1) to assess the effect of chronic exposure to ambient air pollutants on risk of all-cause mortality among persons with COPD …

Perceived Attitudes And Staff Roles Of Community Based Outpatient Clinics In Disaster Management, Pauline Antoinette Hodge-Hilton

Loma Linda University Electronic Theses, Dissertations & Projects

Objective: Natural and manmade disasters have claimed the lives of thousands of individuals in the US and caused billions of dollars in property damage. First responders carry the responsibility of disaster management, leaving other health care professionals such as medical clinic staff underutilized to support the clinic staff. We explored how medical and support staff in Community-based Outpatient VHA Clinics (CBOC) perceive their roles in disaster response, their attitudes about clinic readiness and continuity of care during disasters, and their ability to function in a post disaster environment.

Methods: A mixed method study was conducted to answer questions related to …

Comparison Between Ceph Analysis On Lateral Cephs, Cbct Scans, And Mri Scans, Jeffrey W. Lam

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Most current methods of obtaining images for orthodontic diagnosis and treatment planning involve the use of ionizing radiation. Given that patients often need records taken several times during treatment, an alternative should be found that does not involve ionizing radiation. Magnetic resonance imaging (MRI) exists as a possible alternative. Purpose: The purpose of this study is to compare cephalometric measurements obtained from lateral cephs, cone beam computed tomography (CBCT) scans, and MR scans. Methods: Lateral cephs, CBCTs, and MRIs were taken on 22 patients. 3 separate readers traced the images and the data was analyzed using Bland-Altman plots. Results: …

Periodontal Health Of Anterior Teeth With Two Types Of Fixed Retainers, Andrew I. Corbett

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Fixed retainers for anterior teeth have become a popular method for maintaining the position and function of teeth after orthodontic treatment. Various retainer designs, wire sizes and types have been used over the years. One problem with fixed retainers is that they complicate oral hygiene and therefore might negatively affect the periodontal tissues if left in place for long periods of time. Purpose: The purpose of this study is to compare the periodontal health of maxillary and mandibular anterior teeth retained with two different types of fixed retainers. Methods: Male and female subjects who had been in continuous orthodontic …

Material & Methods: Fifty-one adult female profile photos and lateral cephalograms were collected. Subjects were selected who met three criteria: 1) ANB of 0-2, 2) balanced profile image, and 3) age greater than 18. The image and cephalometric tracing were morphed together to allow software simulation of mandibular prognathia and retrognathia in 2 mm increments. Orthodontists and oral surgeons evaluated morphed …

Role Of Vimf In Gingipain Maturation In Porphyromonas Gingivalis, Arun S. Muthiah

Loma Linda University Electronic Theses, Dissertations & Projects

Gingipain activity in Porphyromonas gingivalis, the major etiological agent in adult periodontitis, is post-translationally regulated by unique Vim proteins including VimF, a putative glycosyltransferase. To ascertain the VimF mediated phenotype we first inactivated the vimF gene in P. gingivalis ATCC 33277 (FLL476), a less virulent fimbriated strain. We observed that the vimF-defective mutant (FLL476) showed a phenotype similar to that of the vimF-defective mutant (FLL95) in the P. gingivalis W83 background. While hemagglutination was not detected and autoaggregationn was reduced, biofilm formation was increased in FLL476. Also, invasive capacity decreased for this mutant. Furthermore, fimbrial structures were missing in FLL476, …

Study Of Brief Single Session Medical Family Therapy With Low-Income Patients, Mayuri Pandit

Loma Linda University Electronic Theses, Dissertations & Projects

Medical Family Therapy (MedFT) has been promoted as beneficial for vulnerable patient populations. However, there is a need for MedFT effectiveness studies with longitudinal randomized control trials. Thus, this pilot study investigated the results of a brief single session of MedFT over a one-week period with low-income primary care patients. Effectiveness in this study was defined as increasing a sense agency and communion and decreasing psychological distress. Results suggested that over time, MedFT may increase some sense of agency for lower-income patients, increase patient satisfaction with care, increase family support for patients with higher education, and decrease depression symptoms for …

Successful Aging And Creativity : An Investigation On Functional Status And Psychological Wellbeing In Older Adults, Mirie E. Levy

Loma Linda University Electronic Theses, Dissertations & Projects

Objectives: While the literature supports the maintenance of functional status as integral to successful aging, the relationship of creativity on functional status has received little attention. Creativity has been associated with health and aging in the research but only a small number of studies have examined creativity interventions to enhance functional status and boost psychological wellbeing.

Methods: A pretest-posttest quasi-experimental design was used to investigate an 8-week creativity intervention on functional status and psychological wellbeing in older adults. Sample subjects were 92 men and women all over age 60. A series of two-way mixed ANOVAs measured differences between treatment and …

Fetal Programming And Later Obesity In A Predominantly Latino Wic Population, Eric George Walsh

Loma Linda University Electronic Theses, Dissertations & Projects

Background: In utero stressors may work to program the metabolism of the developing fetus in such a way that predisposes him/her to obesity later on. Studies have shown that breastfeeding is protective against childhood obesity and suggest that after six months the weight gain in breastfed babies slows opposed to formula fed babies who continue with rapid weight gain. This slowing of weight gain has been shown to be protective against adiposity and later life weight gain.

Purpose: This study looks to further explore these findings in a low income Latino population adding mother’s feelings about the pregnancy and the …
