Changes In The Cant Of The Occlusal Plane Evaluated In Treatment And Its Stability In Retention, Bruce S. Heinrich

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to test the hypothesis that occlusal plane changes induced by orthodontic treatment remain stable during retention, and to show that the occlusal plane cant is related to facial type and occlusal classification.

A comparison of facial type, occlusal classification, extraction status, and growth status was provided. The sample consisted of pretreatment, posttreatment, and postretention cephalometric radiographs of 156 orthodontic cases from the records of Loma Linda University School of Dentistry, Department of Orthodontics. Changes in the cant of the occlusal plane were evaluated by the Frankfort horizontal to occlusal plane angle.

Results showed that …

The Evaluation Of Factors Affecting Adherence To An Exercise Program Among College Students, Mark Robert Dean

Dissertations

Though investigative studies have identified the many benefits of aerobic exercise for both biological and behavioral health, only a small percentage of individuals maintain regular exercise. Team or group exercise programs report higher participation rates, but studies of individually prescribed exercise programs typically report problems of compliance and attrition. The purpose of the present study was to evaluate the effectiveness of various interventions--including the provision of course bonus points, cash lottery, and partner assignment--designed to increase exercise compliance among college students. Thirty-two student volunteers reporting "no current exercise" were randomly assigned to either the "partner" or the "individual" exercise group. …

The Regulation Of Tyrosine Phosphorylation During The Differentiation Of A Human Leukemia, David Alan Frank

Yale Medicine Thesis Digital Library

HL-60 promyelocytic leukemia cells are an excellent model system for studying hematopoietic differentiation. This study sought to determine how tyrosine phosphorylation and the enzymes which regulate it are controlled during HL-60 differentiation.HL-60 cells normally contain about 1.5% of their phosphoaminoacids as phosphotyrosine. Upon granulocytic differentiation, phosphotyrosine content decreases to 0.1 to 0.3% of phosphoaminoacids. HL-60 cells possess a tyrosine kinase activity located in the particulate fraction which can phosphorylate a number of tyrosine-containing substrates in a time- and temperature-dependent fashion. It has a k$\sb{\rm m}$ for ATP of about 20 uM, a pH optimum of 6.4, and a preference for …

Histologic Host Response To Polyoxymethylene Prosthesis As A Temporomandibular Joint Condylar Replacement, Frederick R. Mathews

Loma Linda University Electronic Theses, Dissertations & Projects

Polyoxyinethylene (Delrin) is a polyacetyl homopolymer which has been used successfully in many orthopedic joint replacements. To determine histologic host response to Delrin as a temporomandibular joint condylar replacement condyles were removed from ten fully mature macaca fasicularis monkeys. The condyles were replaced with a total prosthetic Delrin condyle attached to a titanium mesh. Specimens obtained at one, two, and six months indicated total acceptance of the Delrin, remodeling of the glenoid fossa and formation of bone between the middle cranial fossa and the roof of the glenoid fossa. These findings would indicate Delrin is a viable option for condylar …

Quantitation Of Teratogenic Effects Of 5-Fluorouracil Administered To Mice In Vivo Or In Submerged Limb Culture, Theresa A. Sanders

Electronic Theses and Dissertations

This study demonstrates the use of submerged limb culture in teratologic testing. Pregnant mice were treated on day 11 of gestation (E11, plug date = E0) with 10, 20 or 40 mg of 5-fluorouracil (FU) per kg body weight. On E17, treated and untreated fetuses were examined for gross malformations and were fixed in 95% ethanol. Reduction of limb size and digital defects, including ectrodactyly (ED), syndactyly (SD), microdactyly and polydactyly were dose-dependent. In parallel studies, pregnant mice were treated on the morning of E11 and embryos were removed either 7h (E11) or 24h (E12) later for submerged limb culture. …

Adaptation Of Striped Bass To Sea Water Following Direct Transfer From Freshwater: Morphological, Biochemical, And Physiological Parameters, Judy A. King

This descriptive study focused on the bureaucratic, professional, and service role conceptions of nurses. It was hypothesized that there are significant differences in the ideal and actual perceptions of these role orientations among baccalaureate nursing students, their nursing faculty, and their clinical nurse mentors. The three subscales of Pieta's 1976 Nursing Role Conception Scale (NRC) were used. The results of a discriminant analysis indicated significant differences in professional and service nursing role conceptions among students and both their nursing faculty and clinical mentors (p

Comparative Study Of Elongated Chromosomes In Sheep And Goats And A Proposed Standard, Stephen H. Mensher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A cell synchronization technique was used that consistently yielded numerous elongated chromosomes, which are necessary for producing high-resolution G-banding. The prometaphase stage of contraction was determined to have the greatest utility for detailed comparative analysis and, therefore, was used in the preparation of the proposed standard high-resolution karyotypes and idiogram.

A proposed standard high-resolution G-band karyotype of the domestic sheep and goat is presented, along with a high-resolution G-band idiogram of the goat. The karyotypes presented contain considerably more bands than contemporary karyotypes and provide much greater resolution for linear differentiation. The X chromosome of the sheep is acrocentric, rather …

An Otopathological Assessment Of Dogs Exposed To Excessive Dietary Fluoride And/Or Suspected Water Borne Toxins, Barbara Ann Hannah

Masters Theses

In 1970, a once very productive Allegan, Michigan dog kennel began experiencing a rash o£ unexplained perinatal deaths and reproductive anomalies in Shetland pups. Anomalies including cleft palate and lip, kinked tails, twisted feet and convulsions immediately before death plagued the neonates. The adult dogs were reported to have tooth mottling, exostoses and auditory and vestibular problems.

Because the dogs had been on high fluoride diets and because the kennel well water was suspected of harboring toxins, a group of 20 Shetland dogs was used to try to find if there was any correlation between the reproductive problems and the …

The Effect Of Assertiveness Training On Assertive Behavior And Corresponding Self-Descriptive Statements, James Scott Boland

Masters Theses

This study examines the changes in subjects' assertive behavior and corresponding changes in self-perceptions/-cognitions after assertiveness training.

Fasting Plasma Amino Acids In Relation To Serum Lipids In Human Male Subjects, Helen G. Mendiola

Loma Linda University Electronic Theses, Dissertations & Projects

The association of fasting plasma amino acids with serum lipids was studied in 23 healthy human male subjects with ages ranging from 31 to 62 years (45±9, mean± SD). There were 12 normocholesterolemic (serum cholesterol = 183±17 mg/dL) and 11 hypercholesterolemic (271±27 mg/dL) subjects. Venous blood samples were drawn three times at weekly intervals. Plasma amino acids were determined by ion-exchange chromatography, and serum cholesterol and triglycerides by enzymatic methods. Hypercholesterolemic subjects had significantly higher lysine and lower serine levels than normocholesterolemic subjects (p < .05). Serum cholesterol levels were positively correlated with plasma levels of lysine, ornithine and the lysine/arginine ratio (p < .04); and negatively correlated with phenylalanine and urea (p < .05). Serum triglyceride levels were positively correlated with plasma levels of lysine, glutamic acid, and valine (p <. 02); and negatively correlated with serine, glutamine, and asparagine (p < .04). These results add support to the hypothesis that specific plasma amino acids are associated with the metabolism of serum lipids.
