Expression And Requirement Of Epithelial Fatty Acid- Binding Protein In Neuronal Axon Growth, Gregory William Allen

Loma Linda University Electronic Theses, Dissertations & Projects

Epithelial fatty acid-binding protein (E-FABP) is expressed in the dorsal root ganglia following sciatic nerve injury and in migrating and differentiating neurons during neuronal development. It was hypothesized that E-FABP expression is required for the robust outgrowth of axons from developing and regenerating neurons. To test this hypothesis, E-FABP expression in both PC12 cells and primary retinal neurons was examined. In PC12 cells, NGF induces E-FABP mRNA and protein during the period of neurite outgrowth, and E-FABP localizes to the perinuclear cytoplasm, nucleus, and growth cone. Furthermore, E-FABP-deficient cell lines exposed to NGF were less differentiated and had shorter neurites …

Effects Of Pycnogenol On Microsomal Cytochrome P450 Activity And Apoptosis, Huong Thu Huynh

Loma Linda University Electronic Theses, Dissertations & Projects

Phytochemicals are naturally-occurring compounds found in plants, many of which are consumed as nutritional supplements by humans. Pycnogenol is a mixture of flavonoid compounds extracted from bark of pine trees (Pinus maritima) and is commercially available in several different pharmaceutical preparations as a free radical scavenger.

Since few scientific studies have documented the pharmacologic effects of pycnogenol, our objective was to characterize the biological activity of pycnogenol. One study looked at the effects of pycnogenol on the three pathways of NNK metabolism: NNK reduction, N-oxidation and a-hydroxylation. NNK is a lung carcinogen. Lung and liver microsomes from 6 mo and …

Failure Mode Of An Orthodontic Resin Alone And With Bonded Brackets, Marc Cody Dunn

Loma Linda University Electronic Theses, Dissertations & Projects

Since the introduction of bonded orthodontic brackets in the early 1960's spontaneous debonding has been a constant nemesis. Most attempts to avoid this problem by orthodontic manufactures have focused on "bond strength" issue. Whether they chose to address the materials, the bracket base or both, the common method used to evaluate improvements entailed the use of just one testing apparatus: a static universal testing machine such as the Instron.

Metal, ceramic and plastic bonded brackets were tested with the traditional shear/peel method as well as a new high strain rate impact test. The resin itself was also evaluated for physical …

Identification And Characterization Of Control Elements Within The Murine Cd4 Gene, Zhong Deng

Loma Linda University Electronic Theses, Dissertations & Projects

The control of CD4 gene expression is essential for T lymphocyte development. Since the molecular mechanism for the control of CD4 gene expression during T cell development had not been elucidated, a study of the factors that control CD4 gene expression may lead to further. Toward these goals, we have made a series of recombinant DNA constructs to define the cis-acting transcriptional control elements in the murine CD4 locus that control CD4 gene expression during T cell development. In this study, we have identified multiple cis-acting control elements, which are critical for regulating the expression of the murine …

An Extension Of Euclidean Distance Matrix Analysis Applied To Craniofacial Growth Prediction, Mark K. Batesole

Loma Linda University Electronic Theses, Dissertations & Projects

This study is [sic] introduces a new extension of Euclidean Distance Matrix Analysis (EDMA) as applied to growth prediction analysis. Using EDMA eliminates the presupposition of a set growth pattern, which is introduced by traditional superimposition techniques. When EDMA is extended to analyze prediction methodologies, using a non-age-matched growth sample, some shortcomings become evident. These involve bootstrapping techniques, relative difference in growth, and absence of clinical, real world measure. To overcome these issues, a statistical approach using the Wilcoxen signed rank test, absolute difference in growth, and a new method to evaluate the error in a prediction methodology's landmark identification …

Whose Turn Is It Anyway : The Impact Of Job Rotation On The Reduction Of Cumulative Trauma Disorders, Francesco Dimiceli Jr.

Theses

In today's fast-paced world, repetitive activity on the job has become very demanding. Many workers are suffering from injuries known as cumulative trauma disorders (CTDs). Job rotation can be an effective and powerful tool when seeking to minimize CTDs by allowing workers to experience different activities, thereby distributing the physical demands on the workers' bodies.

A case study was conducted on a northwestern New York manufacturing facility to identify the presence of excessive work stressors and to formulate potential corrective actions, including an analysis of their current job rotation system. The jobs were evaluated using the Rapid Upper Limb Assessment. …

The Relationship Between Companion Animals And Health Status Among Older Adults Living In The Community, Agnes M. Eytchison

Master's Projects

A study was conducted on 18 older adult pet owners and non-pet owners residing in a mobile home park to determine self-perception of health status and the level of attachment to pets. Self-reported health status was high and equal for both pet owners and non-pet owners. The level of attachment to the pets was also high. Studies have demonstrated human-animal interactions being beneficial to both individuals and families; but for many residents of mobile home parks and common interest developments, such as condominiums and townhouses, rules prevent companion animal ownership. Family Nurse Practitioners (FNPs) aware of the benefits of animal …

Construction And Testing Of A Marital/Couple Therapy Satisfaction Measure, Jesse Bingham

Open Access Theses

Therapy is inundated with self-report instruments/measures for clients (Corcoran & Fischer, 1987)(Touliatos, Perlmutter, & Straus, 1989); most of them focused for individual therapy. Many of these instruments are used for assessment purposes, while some others are related to outcome (Fredman & Sherman, 1987) (Corcoran & Fischer, 1987). One neglected area is that of instruments devised to measure satisfaction with specific content areas oftherapy. Another neglected area is an instrument designed specifically for marital/couple therapy. This research devised and tested a client self-report satisfaction measure specifically for couples in therapy. The items of the Marital Therapy Satisfaction Measure (MTSM) were derived …

Culture Of Origin And Illness Attribution: The Implications Of Cross-Cultural Awareness For Health Care Professionals, Eri Matsumoto-Lyons

Master's Projects

People from different cultural backgrounds have different beliefs and perceptions concerning health and illness. Differing illness beliefs between health professionals and patients may result in conflicting expectations regarding treatment choice and outcome. This non-experimental research was designed to explore illness attribution among Caucasian, Hispanics, and Asians with chronic or acute illness. The results suggest that there was no significant difference in illness attribution beliefs between the three ethnic groups; however, primary language, years spent in U.S., and educational backgrounds were associated with differences in illness attribution. Health care providers must think of culture in a broader spectrum than just race …

Supervisory Feedback In Speech-Language Pathology: Preferences And Practices., Janet Michelle Gurley

Electronic Theses and Dissertations

Research in the area of clinical supervision has historically been limited, especially in the field of speech-language pathology. Furthermore, those few studies that do exist were primarily published during the decade of the 1980's. Clinical supervision, and specifically its critical component of supervisory feedback, is crucial to all clinical training programs. However, supervision research only mentions the topic of supervisory feedback and neglects the relationship between supervisory feedback preferences and actual supervisory practices. This study was designed to identify and compare supervisor and supervisee preferences and perceptions regarding supervisory feedback, to relate these preferences to a continuum-based model of clinical …

Prominent Signs Of Attention Deficit/Hyperactivity In The Adult, Marcia Katz

Master's Projects

Attention-deficit/hyperactivity disorder (ADHD) is a common neurophyschiatric syndrome which most commonly becomes apparent during the first few years of grade school. While it was previously thought that this disorder remitted before or during adolescence, it has become well established that many patients will have an illness course that persists well into adulthood. The purpose of this study was to determine the 10 most prominent symptoms of ADHD in the adult population. Using the Dunphy and Winland-Brown (1998) "Circle of Caring" conceptual framework and the Wender (1998) Utah Criteria Scale questionnaire, a convenience sample of females (N=l5) from northern California were …
