Late Tertiary Rodents From The Catamarca Province, Argentina : The Field Museum Collections, Lee A. Schremp

Loma Linda University Electronic Theses, Dissertations & Projects

The rodents collected in the 1920's by the Marshall Field Expedition for the Field Museum of Natural History, Chicago, are systematically reviewed and placed within the stratigraphic framework established at the time of collection. One new genus (Proeuryzygomys) and three new species (Abracoma intermedias, Proeuryzygomys diminutiva, and Cayiodon (Lelongia) catamarcensis) are proposed. Two distinct faunas are recognized corresponding to the Huayquerian and Montehermosan Land Mammal Ages respectively. Several computer programs were developed to aid in character analysis.

Chronic Respiratory Disease Symptom Effects Of Long-Term Cumulative Exposure To Passive Tobacco Smoke And To Ambient Levels Of Tsp, Oxidants, So2, And No2 In Southern California, Gary L. Euler

Loma Linda University Electronic Theses, Dissertations & Projects

To assess risk of chronic respiratory disease symptoms due to long-term exposure to the ambient levels of TSP, oxidants, SO2 and NO2 in photochemical air pollution, symptoms were ascertained using NHLBI questions on 8,572 Southern California Seventh-day Adventist, nonsmokers, 25 years and older, who lived eleven years or longer in their 1977 residential area. Tobacco smoke, active and passive, and occupational exposures were measured by questionnaires, as well as lifestyle characteristics relative to pollution exposure such as time spent outside and residence history. A pulmonary function feasibility study was done on a subsample of 86 women 50-64 years of age …

The Effect Of Dietary Alpha - Linolenic Acid On Apparent Risk Factors Of Cardiovascular Disease, Kelvin D. Lindbeck

Loma Linda University Electronic Theses, Dissertations & Projects

Eight healthy male lacto-ovo-vegetarian subjects averaging 28.0 ± 3.6 years of age (22 to 53 years) were fed a diet rich in α-linolenic acid (18:3 ω 3) for four weeks. Arterial blood pressure and body weight were recorded each week. Plasma 6-keto-prostaglandin F_1α (6-keto- PGF_1α ), thromboxane B₂ (TXB₂), total cholesterol, triglyceride, and total phospholipid fatty acid composition were analyzed at 0, 2 and 4 weeks.

Systolic blood pressure increased significantly between weeks 0 and 1 (106.5 ± 2.7 mmHg to 114.0 ± 3.7 mmHg; p < 0.003), but decreased to 107.3 t 2.6 mrHg (p < 0.02) at week 2. There was an insignificant increase in both systolic and diastolic blood pressures after four weeks. There was no significant change in either total cholesterol or triglyceride levels during the four weeks.

Plasma 6-keto-PGF_1α levels increased significantly from 60.13 ± …

Palynology And Age Of The Alvord Creek Formation, Steens Mountain, Southeastern Oregon, Stephen F. Barnett

Loma Linda University Electronic Theses, Dissertations & Projects

The age of the Alvord Creek Formation of Steens Formation, southeastern Oregon, has been a center of controversy since Axelrod's 1944 paleobotanical assignment of a Lower Pliocene age to the tuffaceous leaf-bearing shales. This date varies from earlier determinations by Chaney and MacGinitie that the flora was Mascall (Upper Miocene) equivalent. However, it is more sharply contradicted by the report of a Middle Miocene (Barstovian) fauna in the apparently overlying Steens Basalt and by a 21.3 m.y. radiometric date obtained on a basalt flow 61 meters above the leaf-bearing beds.

Palynomorphs recovered from three exposures of the leaf-bearing beds show …

Third Molar Eruption Prediction, Michael L. Jacobsen

Loma Linda University Electronic Theses, Dissertations & Projects

The diagnosis and treatment of third molars has often been cited as a special problem to the orthodontist. If the prognosis of third molars could be determined, orthodontic treatment could progress on a more positive basis.

This study was designed to provide a method of deciding whether developing third molars will erupt or become impacted.

Records from 130 orthodontically treated cases of Dr. Fredsall⁸ were studied. Several factors were evaluated and measured using the patients' cephalometric radiographs.

The actual fate of the third molars were recorded in the hope it could be used to predict what to expect from …
