Multiple Forms Of Nicotinamide Adenine Dinucleotide Glycohydrolase From Bull Semen, Stanley D. Yeatts Ii

Chemistry & Biochemistry Theses & Dissertations

Nicotinamide adenine dinucleotide glycohydrolase (NADase) of bull semen is an extracellular, soluble enzyme capable of catalyzing the hydrolysis of the nicotinamide N-ribosidic linkage of NAD⁺. In search for a rapid, simple procedure for the preparation of this enzyme, it was found that Matrex Gel Red A (Amicon) column packing served very well as an affinity gel for NADase. The enzyme was applied to the Matrex Red A column (21 cm x 1.5 cm) in 10 mM sodium phosphate buffer, pH 6.0. Surprisingly, two fractions of NADase activity were obtained when the column was eluted with a sodium chloride …

A Comparative Study On The Frequency Of Respiratory, Gastrointestinal, And Allergic Disorders Between Bottle-Fed And Breast-Fed Infants From Birth To Twelve Weeks Of Age, Sylvia C. Souza

Loma Linda University Electronic Theses, Dissertations & Projects

Questions concerning the advantages of breast-feeding have been debated since the introduction of commercially-prepared formula about 50 years ago. Some recognized benefits of breast milk include less respiratory as well as other Infections, less allergy in infancy and later life, and a lower morbidity rate in less-developed countries. From 1955 to 1971 in the United States there was a decline in the incidence of breast feeding related to several factors which included the introduction of formula, mothers returning to the work force, and strict maternity units' rules and routines. Since 1971 to the present there has been a resurgence in …

Richmond Smith As A Clinical Investigator: His Work On Adult Periosteal Bone Expansion And Nutritional And Endocrine Aspects Of Osteoporosis In Light Of Current Concepts, A. M. Parfitt

Henry Ford Hospital Medical Journal

This paper discusses Richmond Smith's contributions to the field of metabolic bone disease from 1949 to 1969 in light of current concepts. He was the first to demonstrate continuing periosteal bone expansion in adults, a phenomenon of great biologic interest which is best explained if adult bone remodelling is qualitatively similar on all surfaces. He was the first to show that persons with less bone than normal have an increased risk of subsequent fracture, and so are more likely to benefit from preventive treatment. He found that blood vitamin D levels were lower in osteoporotic subjects than in controls, but …

Insulin-Resistant Diabetes Mellitus And Insulin Receptor Antibodies: Variable Association With Acanthosis Nigricans, José Goldman

Henry Ford Hospital Medical Journal

Two patients with severe insulin-resistant diabetes mellitus and anti-insulin receptor autoantibodies are reported here. A marked decrease in the number of accessible insulin receptors was found in the monocytes of one patient. Otherwise, the Insulin receptors were of normal affinity compared to those of normal controls. Acanthosis nigricans was not present in one patient, and in the other patient it preceded the diagnosis of diabetes by ten years. We conclude that although acanthosis nigricans and insulin resistance are frequently associated, they probably do not bear a pathogenetic relationship to each other. Therefore, the investigation of anti-insulin receptor antibodies Is advisable …

Lipoprotein Lipase Inhibitor Removal During Ultrafiltration Of Renal Failure Patients, Alisa Minear

Loma Linda University Electronic Theses, Dissertations & Projects

Plasma samples were obtained from seven hypertriglyceridemic (>150 mg/dl) chronic renal failure patients before and after regular hemodialysis. The effect of the plasma on the lipolytic activity of bovine milk lipoprotein lipase was investigated. The lipoprotein lipase activity, as measured by release of C¹⁴-labeled free fatty acid from triglyceride, was decreased 8-67% when incubated with uremic plasma as compared to the control plasma (44 mg/dl triglyceride). The inhibition noted prior to hemodialysis did not appear to be alleviated by the dialysis but subsequent treatment with an isolated ultrafiltration technique did appear to remove an inhibitory substance as …

Evaluation Of New Attachment Following Full Thickness Flap Procedure In Humans, Shaunda S. Steiner

Loma Linda University Electronic Theses, Dissertations & Projects

A study was made to investigate the biological possibility of obtaining new connective tissue attachment to periodontally diseased root surfaces following full thickness flap procedure. Reconstructive surgery was performed on seven teeth involved in advanced chronic periodontal disease. A mucoperiosteal flap was raised and the apical extent of existing subgingival calculus was marked with a notch made into the root just apical to the calculus. Following thorough instrumentation, sterile saline was applied to the root surface for five minutes, and the flap was repositioned and sutured. Four months later the teeth with attached periodontal tissues were removed and processed for …

Toxicity Of Root Canal Filling Materials On Hela Cells And Fibroblasts, Eldon P. Carman

Loma Linda University Electronic Theses, Dissertations & Projects

A study was undertaken to determine the concentration at which a sealer reaches a point of nontoxicity. An in vitro model utilizing HeLa cells and human fibroblasts was used to observe the effect of various concentrations of eight freshly mixed and eight set root canal sealers. Evaluation of toxicity was determined by cell survival which was measured by incorporation of ³H-thymidine into the nucleic acid components of each cell type used. Each dilution tested was allowed direct contact with the cells for 24 hours before toxicity evaluation. The results indicate that all sealers at concentrations presently used are cytotoxic …

Orthognathic Surgical Expansion Procedure Of The Mandible Of Female Baboon Papio Sp?, Willis L. Schlenker

Loma Linda University Electronic Theses, Dissertations & Projects

Expansion of the maxillae is a well recognized procedure in orthodontics. Little is known about Mandibular Expansion. This project is a pure research of the possibility of expanding the mandible laterally at the symphysis on a baboon.

The symphysis was cut A-P and expanded laterally 11 mm, then held and stabilized with a titanium mesh work screwed to the inferior border of the mandible. The defect area was filled with a bone graft of marrow and cancellous bone fragments taken from the greater trochanter and the crest of the ilium. New bone did fill in the defect and the expansion …

An Ultra-Violet Light Microscopic Study Of The Hydroxylapatite Ceramic-Bone Interface Phenomena, Leonard W. Pierce

Loma Linda University Electronic Theses, Dissertations & Projects

Preparations used in this study were obtained from an investigation which had undertaken the following:

Durapatite, a hydroxylapatite ceramic was implanted in 24 mature Beagle dogs to study its maintenance effect on the alveolar bone of the mandible.

After dividing the dogs into two groups, a fresh socket and a healed socket group, the posterior teeth were removed and alveolectomies were performed. Eight ceramic implants were then placed in the right mandible of each animal in each group. The healed group received the implants five weeks after tooth removal and the fresh socket group received implants immediately after extraction.

Effects Of Relaxation Therapy On Anxiety In Depressed Clients, Patricia Anne Worret

Loma Linda University Electronic Theses, Dissertations & Projects

During a psychiatric field placement, it was noted by this nurse researcher that patients with a diagnosis of depression often overtly displayed symptoms of anxiety. A brief literature review revealed that this anxiety-depression duality occurred frequently.

The purpose of this study was to determine if relaxation therapy was a therapeutic intervention which could be utilized by nurses to provide relief from the symptoms of the anxiety-depression syndrome. This was a clinical, quasi-experimental research investigation. The sample was chosen by a purposive, non-random selection of 20 experimental and 10 control subjects who were hospitalized with a diagnosis of depression in an …

Only a few of these studies, however, have been conducted on registered nurses, a major group involved with shift work.

The purpose of the present study was to investigate the effects on nurses working the a.m. shift (7 a.m. to 3:30 p.m.), …

Development Of Age Normative Data For The Oral Language Sentence Imitation Screening Test, Melinda Diane Roos

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this investigation was to develop objective pass/fail age-related scores for the Oral Language Sentence Imitation Screening Test (OLSIST). A group of 60 children, ages five years zero months to five years eleven months, served as subjects. The Denver Articulation Screening Exam (DASE), and the Screening Test For Auditory Comprehension of Language (STACL) were used to determine if each child's articulation and receptive language abilities were within normal limits. Each subject's scores on the OLSIST were then compared with his/her score on the CELI to determine the degree of correlation in pass/fail performances on the two tests.

An Avoidance Response Bioassay For Aquatic Pollutants, Jeffrey A. Black, Wesley J. Birge

KWRRI Research Reports

Avoidance response bioassays were conducted with eight aquatic contaminants, including cadmium, copper, mercury, zinc, chloroform, dioctyl phthalate (DOP), trisodium nitrilotriacetic acid (NTA), and phenol. Tests were performed in a dual-channel fluviarium system, and the toxicant injection procedure used provided good regulation of exposure concentrations. Juvenile stages of largemouth bass (Micropterus salmoides), bluegill sunfish (Lepomis macrochirus), and rainbow trout (Salmo gairdneri), and tadpoles of the American toad (Bufo americanus) proved to be suitable animals for evaluating avoidance or attraction responses. The trout was the most sensitive species tested.

Avoidance was significant in tests …
