Periodontal Repair In Dogs : Effect Of Recombinant Human Transforming Growth Factor Beta-1 On Guided Tissue Regeneration, Saghi Shayan Razi

Loma Linda University Electronic Theses, Dissertations & Projects

The objective of this study was to evaluate bone and cementum regeneration in the critical size, supraalveolar, periodontal defect model following surgical implantation of recombinant human transforming growth factor beta-1 (rhTGFß-1) in conjunction with guided tissue regeneration (GTR). Five male beagle dogs were used in a split-mouth design. Alternate jaw quadrants in consecutive animals received GTR with rhTGFß-1 in a resorbable calcium carbonate carrier. Contralateral jaw quadrants received GTR with carrier only (control). The healing interval was 4 weeks. Clinical healing was generally uneventful, however, minor membrane exposures were observed for both treatments with limited gingival inflammation. All defects with …

The Effect Of Guidor™ And Hop-1 On Hard Tissue Healing : Following Periradicular Surgery In Cats, Hugh Maguire

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the effects of the resorbable membrane Guidor™ and the osteogenic protein hOP-1 on hard tissue healing following periradicular surgery in cats.

Surgical endodontic therapy was performed on the maxillary canine teeth of twelve cats. After orthograde root canal therapy, flap reflection, osteotomy, resection of the root end, root end cavity preparation and the placement of a root end filling, eight of the surgical sites were treated with Guidor™ and eight with hOP-1. The remaining eight sites received no further treatment and served as controls.

An Enzyme-Linked Immunosorbent Assay For The Detection Of Cardiac Myoglobin Using Monoclonal Antibodies, Deborah F. Kelly

Chemistry & Biochemistry Theses & Dissertations

The most prevalent life-threatening disease worldwide, secondary to coronary artery thrombosis is Acute Myocardial Infarction (AMI). Increases in three clinical markers have been explored as an early means of AMI detection: Cardiac myoglobin, and the two specific cardiac isoforms of Creatine Kinase, CK-MM and CK-MB. However, myoglobin levels have shown to give a more accurate correlation (R = 0.89) than does Creatine Kinase evaluation. Therefore, we have developed a two-site Enzyme-Linked Immunosorbent Assay (ELISA) using monoclonal antibodies against myoglobin isolated from human heart tissue. This assay is based on specific anti-genantibody interactions and is sensitive at the nanogram level. We …

Disruption Of The Cbfa2 Gene Causes Necrosis And Hemorrhaging In The Central Nervous System And Blocks Definitive Hematopoiesis., Qing Wang, Terryl Stacy, Michael M Binder, Miguel Marin-Padilla, Arlene H. Sharpe, Nancy A. Speck

Dartmouth Scholarship

The CBFA2 (AML1) gene encodes a DNA-binding subunit of the heterodimeric core-binding factor. The CBFA2 gene is disrupted by the (8;21), (3;21), and (12;21) chromosomal translocations associated with leukemias and myelodysplasias in humans. Mice lacking a CBF alpha 2 protein capable of binding DNA die between embryonic days 11.5 and 12.5 due to hemorrhaging in the central nervous system (CNS), at the nerve/CNS interfaces of cranial and spinal nerves, and in somitic/intersomitic regions along the presumptive spinal cord. Hemorrhaging is preceded by symmetric, bilateral necrosis in these regions. Definitive erythropoiesis and myelopoiesis do not occur in Cbfa2-deficient embryos, and disruption …

Association Between Nutrient Intake And Risk Of Coronary Heart Disease In California Seventh-Day Adventists, Peter Pribiš

Loma Linda University Electronic Theses, Dissertations & Projects

Dietary habits are believed to be major determinants of risk of coronary heart disease (CHD). Studies of high and low risk populations have suggested several nutrients to be protective or hazardous against CHD. Most published work since 1984 on diet and CHD in the Adventist Health Study (AHS) population examined either foods or food groups. This study investigated ten nutrients as exposure variables and their relationship to CHD risk. A cohort of 23,616 nonsmoking, non-Hispanic white California Seventh-day Adventists was followed for six years beginning in 1976. Extensive dietary information was collected at baseline, as well as values of traditional …

Job Accommodation In The Automobile Industry : Addressing The Problem Of Lateral Epicondylitis, Thanigaivel Ashwin Raj

Theses and Dissertations (ETD)

Cumulative trauma disorders are musculoskeletal problems such as carpal tunnel syndrome, rotator cuff tendinitis, and epicondylitis which can affect assembly line workers. The injuries are thought to result from repetitive motions performed under excessive loads in anomalous postures. The project aimed to design, build, install, and evaluate worksite accommodation at the Saturn plant for a worker with right lateral epicondylitis. The goal was to make her fully functional in her original team which required addressing the injurious aspects of the task that caused or aggravated her injury.

A process of observation, interview, and analysis identified “the door mount” operation on …

Counseling And Testing For Hiv Prevention: Costs, Effects, And Cost-Effectiveness Of More Rapid Screening Tests, P. G. Farnham, Robin D. Gorsky, D. R. Holtgrave, Wanda K. Jones, Mary Guinan

School of Public Health Faculty Research

New rapid human immunodeficiency virus (HIV) antibody tests permit many individuals to receive test results and appropriate counseling at one clinic visit. Because currently used tests require significant time for processing, all individuals must return for a second visit for test results and counseling. Since return rates for the second visit are low, the more rapid tests present an opportunity to improve the efficiency of HIV counseling and testing.

The authors compared the costs and effectiveness of the currently used counseling and testing procedure and a streamlined procedure made possible by the new, more rapid screening tests. When test-positive clients …

Preventing Perinatal Transmission Of Hiv Costs And Effectiveness Of A Recommended Intervention, Robin D. Gorsky, P G. Farnham, Walter L. Straus, Blake Caldwell, D R. Holtgrave, R. J. Simonds, M F. Rogers, Mary Guinan

School of Public Health Faculty Research

In the United States, nearly all new human immunodeficiency virus (HIV) infections in children are acquired through perinatal (mother-to-infant) transmission. Each year, approximately 7000 infants are born to HIV-infected women in the United States.¹ Without intervention, an estimated 15-30% of these infants would become infected.² In 1994, results of the AIDS Clinical Trial Group (ACTG) Protocol 076 showed that treatment of infected pregnant women and their infants with zidovudine (ZDV) reduced the rate of perinatal HIV transmission from 25% to 8%.^3,4 Following these findings, the Public Health Service (PHS) issued recommendations for ZDV therapy to prevent perinatal …

Behavioral Science And Public Health: A Necessary Partnership For Hiv Prevention, Martin Fishbein, Mary Guinan

School of Public Health Faculty Research

We are now in the second decade of the AIDS epidemic in the United States. As of October 31, 1995, a total of 311,381 U.S. citizens had t died from AIDS, another 189,929 had been diagnosed with AIDS (1), and it is estimated that nearly l million persons are infected with HIV, the virus that causes AIDS (CDC). Despite the best efforts of biomedical researchers, we still have neither a cure nor a vaccine to prevent this deadly disease. Yet AIDS is a preventable disease; AIDS is first and foremost a consequence of behavior. It is not who you are, …

Virulent Footrot : Mild Or Severe?, Laurie Depiazzi

Journal of the Department of Agriculture, Western Australia, Series 4

The footrot eradication scheme in Western Australia has resulted in a low prevalence of severe footrot.

To appreciate the achievement, we need to understand what exactly is being eradicated. 'S' strains of Dichelorbacter nodosus, the infectious bacterium of footrot, are the target of footrot eradication. Laurie Depiazzi examines the basis for eradicating 'S' strains.

The History Of Pathology In Texas, Marilyn Miller Baker

Texas Medical History E-Books

The History of Pathology in Texas is the study of the changes of disease in Texas from the frontier days to the 1990s. Marilyn Miller Baker wrote the book for the Texas Society of Pathologists. The book was published in 1996 with a forward by Vernie A. Stembridge, MD, the Ashbel Smith Professor and Chairman Emeritus of Pathology at the University of Texas Southwestern Medical Center at Dallas. The book covers the story of pathology from the "performance of crude autopsies" on the frontier through the emergence of bacteriology and immunology and beyond.

Localized Tuberculosis And Myelofibrosis With Myeloid Metaplasia : An Extremely Unusual Presentation, Suhail Muzaffar

Department of Pathology and Laboratory Medicine

Myelofibrosis with myeloid metaplasia (MMM) is usually considered primary agnogenic, however, it may be secondary to various diseases, The association of tuberculosis with MMIM is exceedingly rare, however, the pathogenetic relationship between the two is difficult to define. We present a case report showing simultaneous presentation of localized active tuberculosis and MMM The literature on the subject is also reviewed with special emphasis on pathogenic relation­ship between the two.

Ventricular Remodeling Following Infant-Pediatric Cardiac Transplantation. Does Age At Transplantation Or Size Disparity Matter?, Girish S. Shirali, F Lombano, W L. Beeson, D A. Dyar, N F. Mulla, A Khan, J K. Johnston, R E. Chinnock, S R. Gundry, A J. Razzouk

Manuscripts, Articles, Book Chapters and Other Papers

Early left ventricular (LV) remodeling following pediatric cardiac transplantation has not been described. To identify patterns and determinants of change in left ventricular mass and volume posttransplant, we studied 125 consecutive children who underwent cardiac transplantation between January 1, 1989 and July 31, 1993. Two-dimensional imaging-directed M-mode echocardiograms were studied weekly until 26 weeks post-transplant. LV mass and volume (indexed to BSA1.5) were measured. LV mass index increased until 3 weeks post-transplant, and then decreased. The mean decrement in LV mass index after 8 weeks post-transplant (relative to baseline) was significantly larger in patients with donor-recipient weight ratio > 1.5 compared …

Repellence Of The Tick Rhipicephalus Appendiculatus By The Grass Melinis Minutiflora, Esther N. Mwangi, S. Essuman, G. P. Kaaya, E. Nyandat, D. Munyinyi, M. G. Kimondo

All Peer-Reviewed Publications

In a study to develop anti-tick pastures, the climbing behaviour of Rhipicephalus appendiculatus on Melinis minutiflora (molasses grass) was investigated. Experiments were done with cut green stems of grass, grass dried in the shade, grass dried in sunshine, grass washed in solvent and grass growing in a study plot. In all cases a common pasture grass, Pennisetum clandestinum (Kikuyu grass), was used as control. All instars of the tick avoided climbing on the green M. minutiflora whereas most larvae, nymphs and adults climbed on the control green P. clandestinum grass. More ticks climbed on the stems dried in the sunshine …

Fish Health For Fish Farmers In Western Australia, Tina Thorne

Fisheries Published Reports

Disease is a departure from the normal state of health of a fish or any other animal. Diseases have no doubt occurred among fishes since these animals have occupied a place on the earth. Scientific efforts to understand the causes of disease in fishes, and to attempt to control them however, have only been made during the last sixty years.

Fishes, crustaceans and molluscs, as with other animals are subject to a wide spectrum of diseases, that can be classified as infectious or non-infectious. The vast majority of disease problems in the intensive farming of aquatic animals can be traced …

Transactivation Of The Moloney Murine Leukemia Virus And T-Cell Receptor Beta-Chain Enhancers By Cbf And Ets Requires Intact Binding Sites For Both Proteins., Wanwen Sun, Barbara J. Graves, Nancy A. Speck

Dartmouth Scholarship

The Moloney murine leukemia virus (Mo-MLV) enhancer contains binding sites (LVb and LVc) for the ets gene family of proteins and a core site that binds the polyomavirus enhancer-binding protein 2/core-binding factor (cbf) family of proteins. The LVb and core sites in the Mo-MLV enhancer contribute to its constitutive activity in T cells. All three binding sites (LVb, LVc, and core) are required for phorbol ester inducibility of the Mo-MLV enhancer. Adjacent binding sites for the ets and cbf proteins likewise constitute a phorbol ester response element within the human T-cell receptor beta-chain (TCR beta) enhancer and contribute to constitutive …

Asbestos Induces Nuclear Factor Kappa B (Nf-Kappa B) Dna-Binding Activity And Nf-Kappa B-Dependent Gene Expression In Tracheal Epithelial Cells., Yvonne M. Janssen, Aaron Barchowsky, Melinda Treadwell, Kevin E. Driscoll, B T. Mossman

Dartmouth Scholarship

Nuclear factor kappa B (NF-kappa B) is a transcription factor regulating expression of genes intrinsic to inflammation and cell proliferation--features of asbestos-associated diseases. In studies here, crocidolite asbestos caused protracted and dose-responsive increases in proteins binding to nuclear NF-kappa B-binding DNA elements in hamster tracheal epithelial (HTE) cells. This binding was modulated by cellular glutathione levels. Antibodies recognizing p65 and p50 protein members of the NF-kappa B family revealed these proteins in two of the DNA complexes. Transient transfection assays with a construct containing six NF-kappa B-binding DNA consensus sites linked to a luciferase reporter gene indicated that asbestos induced …

Are Non-Diabetic Women With Abnormal Glucose Screening Test At Increased Risk Of Pre-Eclampsia, Macrosomia And Caesarian Birth?, Khalid S. Khan, Firasat A. Hashmi, J H. Rizvi

Department of Obstetrics & Gynaecology

To determine, in non-diabetic women, the relationship of abnormal glucose screening test, with the incidence of pre-eclampsia, macrosomia and caesarian delivery, from 1988-92, 5646 consecutive women attending antenatal clinic were screened with a glucose challenge test (GCT) on their first visit (usually at 16-20 weeks); those with risk factors i.e., history of unexplained perinatal loss, macrosomia or family member with diabetes and an initial abnormal screening test were rescreened at 28-32 weeks, In 482 cases the GCT was abnormal (plasma glucose value was >140 mg% 2 hours after 75g glucose challenge). Of these, 292 had one or more abnormal critical …
