Loma Linda University Electronic Theses, Dissertations & Projects

Fasting blood samples were collected from 26 omnivore and 27 vegetarian men (35-60 years of age), who were not taking any medications and by self-assessment were in good health. The following analyses were done: glucose (Glu), glycohemoglobin (HBA1), total serum cholesterol (chole), high density lipoprotein-cholesterol (HDD, low density lipoprotein (LDL), very low density lipoprotein (VLDL), platelet factor four (PF4), and beta-thromboglobulin (BTG). In addition, the blood pressure (BP) was determined.

The systolic (p<0.001) and diastolic BP (p=0.016) were lower in the vegetarian subjects than in the omnivores. The serum total cholesterol levels were also lower in the vegetarian subjects compared to the omnivores (p<0.05). There was no significant difference in Glu, HBA1, LDL, VLDL, HDL, PF4, and BTG levels between the two groups.

The Effects Of Strain Differences On The Binding Of Concavalian A To Mouse Sperm, Lisa A. Mckay

Honors Theses

The current study, lectins were used as genetic probes to determine the phenotype of the sperm from different strains of mice. Lectins are proteins of non-immune origin, which bind to specific carbohydrates (McCoy, 1986). Being that virtually all cell membranes contain carbohydrate components, lectins have been used to identify all types of cells. In this study, a biotinylated lectin Concavalian A (Con A) derived from Canavalia ensiformis, was used and binding was detected using an avidin-biotin peroxidase (ABP) complex technique. The object of the current research was to 1) determine if mouse strain differences have an effect on lectin binding, …

Corticotomy Facilitated Orthodontic Treatment In Adults : A Report Of Two Cases, Randall E. Hoff

Loma Linda University Electronic Theses, Dissertations & Projects

The corticotomy procedure is a surgical technique that has been used to facilitate orthodontic treatment for many years. Proponents of this technique contend that occlusal results are more stable and treatment time is reduced. In this study, two cases of dento-alveolar abnormality are presented that were successfully treated in a relatively short time by using the combined efforts of the surgeon and the orthodontist. Although corticotomy has limited applications, it has a place in the armamentarium of the modern orthodontist.

Key Words: Corticotomy, Adult Orthodontics, Osteotomy.

Enzyme-linked immunosorbent assays (ELISAs) were employed, as well as "immunoblotting" and immunocytochemical techniques. HCK was isolated using Triton X-100 and "high-salt” buffers and exhibited seven major polypeptide bands on SDS-PAGE (41-58 kd). Antisera were made toward HCK and the two major HCK bands. Other immunochemicals included antisera toward AH, the three major AH bands, and HSCK, as well as 3 …

Interaction Of Putative Estrogens And The Estrogen Receptor System In Leydig Cells In The Balb/C Mouse Testis Resulting In The Initiation Of Dna Synthesis, R. Lloyd Juriansz

Loma Linda University Electronic Theses, Dissertations & Projects

Continuous administration of estrogens for 7-9 months, both steroidal and nonsteroidal, to male BALB/c mice, leads to the formation of testicular Leydig cell tumors. Three days following the subcutaneous implantation of a pellet of estrogen in cholesterol, there is a peak in the incorporation of ³H-tymidine into the DNA of the interstitial cells. These effects are hypothesized to be mediated by the estrogen receptor system in the Leydig cell. Common experimental techniques for the measurement of hormone binding, such as dextran coated charcoal treatment, proved to be impossible to employ in this system, therefore a procedure was developed using …

Axial Morphology And Angulation Of The Condyle In Relation To Malocclusions In Different Age Groups, Gerald P. Tadej

Loma Linda University Electronic Theses, Dissertations & Projects

Recent studies have shown that forces applied to the mandible during functional appliance and other orthodontic therapies produce measurable changes in the TMJ. It was postulated that specific malocclusions might also apply forces that could produce specific changes in the horizontal morphology of the TMJ. This study involved 104 pretreatment orthodontic patients, 44 males and 60 females. A submento-vertex analysis was performed and correlated with clinical findings including age, sex, malocclusion type, facial type, TMJ symptoms, tooth eruption sequence, crossbites and midline discrepancies. All possible correlations between the radiographic findings and the clinical malocclusions were tested with ANOVA. The width …

Quick Ceph™, A Computer Program For Cephalometric Analysis And Treatment Planning, Günther Blaseio

Loma Linda University Electronic Theses, Dissertations & Projects

The quantification of cephalometric radiographs is an integral part of orthodontic treatment planning. Numerous computer programs have been designed to digitize headfilms and to provide accurate graphic output and exact measurements. Yet these early systems were either huge, bulky and expensive or were limited in their practical use. The aim of this development was to combine modern computer and electronic equipment with advanced software engineering. The result is a universal cephalometric program written in the computer language "C" with presently seven standard and virtually limitless user definable analyses, growth forecasting, mouse-driven interactive VTO, arch length calculation, superimpositions, table of values …

The Effects Of Two Management Techniques On The Generalization Of A Syntax Structure, Karin Jeanne Goodling

Dissertations and Theses

The effectiveness of any language training program is determined by generalization of the clinically trained behaviors to spontaneous speech. Traditional language programs which employ operant procedures to establish the behavior in the clinic and reinforcement from family, teachers and peers in a variety of settings to obtain generalization, have been successful in establishing the use of grammatical rules in the clinic setting, but reportedly have failed to promote generalization. Recent literature in the areas of semantics and pragmatics has produced a trend toward teaching language in natural contexts. The purpose of this study was to investigate: 1) whether a group …
