Loma Linda University Electronic Theses, Dissertations & Projects

The relationship between moderate exercise training (five 45 min sessions/week, brisk walking at 62+2% V0_2max for 15 weeks) and changes in nutrient intake was investigated in a group of 36 sedentary, mildly obese women, conducted using a two (exercise, EX and nonexercise, NEX groups) x three (baseline, six-, 15-week testing sessions) factorial design, with data analyzed using repeated measures ANOVA. The pattern of change over time between groups for kilocalorie intake tended to be different between groups [F(2,68)=2.50,p=0.089] with the EX group experiencing a significant decrease versus baseline by 15 weeks. Significant group x time interactions were found for …

The Assessment Of Phonological Processes : A Comparison Of Connected-Speech Samples And Single-Word Production Tests, Susan A. Pinkerton

Dissertations and Theses

The purpose of this study was to determine if single-word elicitation procedures used in the assessment of phonological processes would have highly similar results to those obtained through connected speech. Connected speech sampling provides a medium for natural production with coarticulatory influence, but can be time-consuming and impractical for clinicians maintaining heavy caseloads or working with highly unintelligible children. Elicitation through single words requires less time than a connected-speech sample and may be more effective with highly unintelligible children because the context is known, but it lacks the influence of surrounding words. Given the inherent differences between these two methods …

Analysis Of Cholesterol Screening Practices, Jane Mattina

MSN Research Projects

Cardiovascular disease, which consists of hypertension, coronary heart disease, and cerebrovascular accidents, affects over 82 million American adults and is currently the leading cause of death in the United States. The Center for Disease Control and Prevention (CDC) identifies high-blood cholesterol as one of the main risk factors in the development of these diseases. Furthermore, 71 million Americans report having a high-blood cholesterol level, yet only about one third of those people have it under control (CDC, 2014c). The National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines recommend that adults 20 years or older be screened …

Studies On The Activation Of Human Blood Coagulation Factor Vii And Its Interaction With Tissue Factor, Peter Wildgoose

Biomedical Sciences ETDs

Factor VII is a trace vitamin K dependent plasma glycoprotein that circulates in blood as a single-chain zymogen and plays an important role in the initiation of the extrinsic pathway of blood coagulation. Single chain factor VII is converted to two chain factor VIIa by proteolytic cleavage of a single internal peptide bond. Factor VILa in tum activates either factor IX or factor X in a reaction that requires a lipoprotein cofactor designated tissue factor. The activation of factor VII by factor IXa and factor Xa was studied on the surface of a human bladder carcinoma cell line as well …

Death Preparation: The Construct And A Proposed Predictor Of Death And Death Anxiety, Robert A. Papazian

All-Inclusive List of Electronic Theses and Dissertations

In previous studies, death preparation has often been narrowly defined as involving formal and informal educational opportunities (e.g., Bailey, 1976; Miles, 1980; Watts, 1977). In the present study this construct was defined as the quantity (aggregate) and quality (resolution) of experiences, cognitions, and affective processes in response to anticipatory, perceived, analog, and actual loss. A 132 item questionnaire was developed to assess experiential, cognitive, and affective preparation. Quantitative measures of exposure to death-related events as well as the qualitative measure of subjective adjustment to potential loss were evaluated. Reliability and validity for the construct were established and its relationship with …

Acoustic Characteristics Of Vowels Produced By Men, Women And Children, Laura Arlene Getty

Masters Theses

This investigation was a replication and extension of Peterson and Barney’s (1952) research on the acoustics and perception of vowels. This study explored the acoustic characteristics of 12 vowels produced by 50 men, 50 women and 41 children. Speech samples were tape recorded as subjects read lists of words and isolated vowels. Speech samples were digitized. Speech waveforms, spectrograms and formant frequencies were examined and measured.

The average formant frequency values were similar but not identical to the values reported by Peterson and Barney (1952). The largest discrepancy between the two studies was the degree of overlap among vowel categories, …

Progressive Muscle Relaxation As An Adjunctive Treatment For Moderate Asthmatics, Kellye Hutton Slaggert

Masters Theses

This study examined the effects of parent assisted progressive muscle relaxation (PMR) training on moderate asthmatics. Three children between the ages of 7 and 12 participated in the study. After 3 weeks of PMR training and daily practice, the parents became involved in prompting their children to use PMR when an attack appeared likely.

The findings from this study suggest that parental prompting of PMR was instrumental in decreasing the frequency of attacks, increasing peak expiratory flow rates (PEFR) values, and decreasing the severity of attacks for 2 of the 3 subjects. The long term implications for using PMR as …

The results indicated no correlation between the two fit testing methods overall. However, a moderate correlation was found between the MSA respirators and the two methods. This study found many variables which influence fit testing. These include the type of respirator used (brand and facepiece), the probe …

Effects Of Applied Soil Repellent Finish On Pesticide Residues In Work Clothing, Sandra L. Prior

Community & Environmental Health Theses & Dissertations

This study explores the feasibility of using an applied soil repellent finish, Scotchgard, on 100% cotton denim fabric in order to enhance the removal of atrazine and alachlor residue during the laundering process. The experimental findings provided no statistically significant evidence that Scotchgard fabric protector reduced pesticide residuals on the 100% cotton denim fabric either before or after laundering. A significant finding secondary to the study involved the possible interaction of Scotchgard with the pesticide alachlor, leaving greater amounts of residual on the fabric after laundering than those found with no fabric treatment. This suggests that agricultural workers be cautioned …

Development Of Catalytic Rnas As Potential Anti-Hiv-1 Agents, Pairoj Sae Chang

Loma Linda University Electronic Theses, Dissertations & Projects

RNA molecules with enzymatic activity (ribozymes) targeted to the genome of HIV-1 were developed and demonstrated to mediate site-specific cleavage of the HIV-1 RNA in vitro and to inhibit viral proliferation intracellularly. Two classes of ribozymes that incorporate a "hammerhead" catalytic center were utilized, eotide elements in the viral sequence to provide half of the The first class used nuclcatalytic center. A complementary strand harboring the remaining active site nucleotides was supplied in trans and directed the site-specific cleavage of the HIV-1 RNA target. A second type of ribozyme incorporated the entire catalytic center, minus the site of cleavage, within …

Proto-Oncogene Regulation By Growth Factors In Bone Cells, Harold Lyndon Merriman

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies have shown that bone cells in culture produce a number of growth factors that are important in bone regulation. Chick and mouse primary calvarial cultures consist of a mixture of cell types that make it difficult to interpret the results from these model systems. In contrast, MC3T3-E1 cells are a clonal mouse osteoblast-like cell line. Since MC3T3-E1 cells consist of a single population of calvarial cells, they make an ideal system in which to study the autocrine effects of bone growth factors.

Based on this work, MC3T3-E1 cells are now known to produce IGF-I, TGF-beta and IGF-II in …

Electrophysiology, Cell Calcium, And Mechanisms Of Hepatocyte Volume Regulation, Walid E. Khalbuss

Electronic Theses and Dissertations

The electrophysiologic technique (Reuss, L., Proc. Natl. Acad. Sci. USA 82:6014, 1985) was modified to measure changes in steady-state hepatocyte volume during osmotic stress. Hepatocytes in mouse liver slices were loaded with tetramethylammonium ion (TMA$\sp{+}$) during transient exposure of cells to nystatin. Intracellular TMA$\sp{+}$ activity (a$\sp{\rm i}\sb{\rm TMA}$) was measured with TMA$\sp{+}$-sensitive, double-barreled microelectrodes. Loading hepatocytes with TMA$\sp{+}$ did not change their membrane potential (V$\sb{\rm m}$), and under steady-state conditions a$\sp{\rm i}\sb{\rm TMA}$ remained constant over 4 min in single impalements. Hyperosmotic solutions (50, 100, & 150 mM sucrose added to media) and hyposmotic solutions (sucrose in media reduced by …
