Selective Increases In Antibody Isotypes And Immunoglobulin G Subclass Responses To Secreted Antigens In Tuberculosis Patients And Healthy Household Contacts Of The Patients, R Hussain, G Dawood, N Abrar, Z Toossi, A Minai, M Dojki, J J. Ellner

Department of Pathology and Laboratory Medicine

Mycobacterium tuberculosis-specific antibodies (immunoglobulin M [IgM], IgE, IgG, and IgG subclasses) were determined in 164 tuberculosis patients (pulmonary involvement, n = 135; lymph node involvement, n = 29), 59 healthy household contacts (HC), and 51 healthy endemic donors (EC) by a quantitative enzyme-linked immunosorbent assay for reactivity with culture filtrate. Among the isotypes, significant differences between tuberculosis patient groups with either pulmonary or lymph node involvement and healthy control groups (HC and EC) were detected only for IgG (P < 0.001) and IgG1 (P < 0.001) antibodies. Pulmonary patients also showed a significant difference with IgM (P < 0.01) and IgE (P < 0.05) antibodies. HC showed elevation of only IgM antibodies compared with EC, indicating that IgM antibodies may be an indicator of recent infection with M. tuberculosis. These results suggest that the switching of IgM antibody response to IgG1 is a critical event in disease progression. Polyclonal IgG1, IgG3, and IgE antibodies also showed significant elevation (P < 0.05) in patients compared with EC. A strong correlation (rho = 0.254; P < 0.003) was observed between M. tuberculosis-specific IgG1 and polyclonal IgG1 in patients, suggesting that activations of antigen-specific and polyclonal antibodies are related events. No correlation was found between IgG1 antibodies and purified protein derivative skin test results. Since IgG1 antibody responses to culture filtrate are present only after disease establishment, IgG1 responses could provide a useful diagnostic marker of disease.

Protecting Your Back: Weight Room Management, Peter J. Titlebaum, Gordon Rackley

Health and Sport Science Faculty Publications

Weight room supervision can be a formidable undertaking without the necessary preparations and precautions. Weight room supervisors are much like the Secret Service; that is, no matter what happens, if bad, it is the supervisor's fault. Risk management is more important now than at any point in history. The keys to preventing problems and creating an efficient weight room facility include a highly trained staff and a thoroughly detailed employee manual designed specifically for the weight room.

Competitive Enzyme Immunoassay Of Catechin In Human Blood Serum, Jay Fedorowicz

Chemistry & Biochemistry Theses & Dissertations

( +)-Catechin is a type of polyphenolic compound, and it is enriched in fruits, plants, and various beverages. Polyphenolic compounds also play an important role in the human diet. Many scientists, especially wine researchers, have proposed that(+)catechin and its polymers could have many positive health effects. Thus, it is essential to learn more about (+)-catechin and other polyphenolics. Presently, high performance liquid chromatography is the only method to detect ( + )-catechin levels in human blood serum, but this method has the high cost of instrumentation and does not provide good sensitivity. The objective of this project is to develop …

Biochemical And Molecular Characterization Of The Prostate-Specific Membrane Antigen (Psma), John Karl Troyer

Theses and Dissertations in Biomedical Sciences

Prostate cancer is the most common malignancy and the second leading cause of cancer death in males in the United States. Additionally, the number of deaths attributed to prostate cancer is increasing at a rate of approximately 8% a year. Development of new diagnostic and therapy strategies are needed in order to improve the life expectancy of patients with this disease. One tool which may allow for improvements in prostate cancer diagnosis and therapy is the monoclonal antibody (MAb) 7E11-C5.3 which was first described in 1987. Since then, the antigen recognized by MAb 7E11-C5.3 has been named the prostate specific …

Involvement Of P59FynT In Interleukin-5 Receptor Signaling, Mark W. Appleby, James D. Kerner, Sylvia Chien, Charles R. Maliszewski, Subbarao Bondada, Roger M. Perlmutter

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Previous studies implicate the nonreceptor protein tyrosine kinase (PTK) p59fyn in the propagation of signals from the B cell antigen receptor. To elucidate the functions of this kinase, we examined B cell responsiveness in mice engineered to lack the hematopoietic isoform of p59fyn. Remarkably, antigen receptor signaling was only modestly defective in fyn^Tnull B cells. In contrast, signaling from the interleukin (IL)-5 receptor which ordinarily provides a comitogenic stimulus with antiimmunoglobulin, was completely blocked. Our results document the importance of p59fyn^T in IL-5 responses in B cells, and they support a general model …

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 …

Ph And Calcium Dependence Of Hemolysis Due To Rickettsia Prowazekii: Comparison With Phospholipase Activity, David M. Ojcius, M. Thibon, C. Mounier, Alice Dautry-Varsat

All Dugoni School of Dentistry Faculty Articles

Rickettsia prowazekii invades nucleated cells through phagocytosis and subsequently proliferates in the cytoplasm of the host cell. Hemolysis and a phospholipase A2 (PLA2) activity at neutral pHs have previously been reported; even though the phagosomal environment is most likely acidic. We here show that R. prowazekii and R. typhi also lyse erythrocytes at mildly acidic pHs, compatible with an early phagosomal compartment. For R. prowazekii, hemolysis at an acidic pH but not a neutral pH is enhanced by Ca2+, raising the possibility that more than one membranolytic factor may be produced by the rickettsiae. The rickettsiae alone display PLA2 activity, …

Evaluation Of Nitric Oxide In Respiratory Distress Syndrome, Kimberly S. Myruski

Loma Linda University Electronic Theses, Dissertations & Projects

Little is known of the effects of low concentrations of inhaled nitric oxide (NO) on pulmonary mechanics and lung volumes in premature newborn infants with lung disease. Cardiopulmonary function tests including blood gas analyses were obtained from eleven premature lamb models with respiratory distress syndrome to determine if compliance, airways resistance, tidal volume, functional residual capacity, and gas exchange were affected. The effect of inhaled NO on the direction of shunting through the ductus arteriosus was determined using echocardiography.

Twin lambs were cannulated with arterial and venous catheters and intubated with an endotracheal tube before delivery on gestational day 126-130 …

Alveolar Bone And Cementum Regeneration Following Periodontal Reconstructive Therapy : A Review Of Histologic Observations In Man And Experimental Animals, Karen E. Rodden

Loma Linda University Electronic Theses, Dissertations & Projects

Periodontal regeneration includes the formation of both alveolar bone and cementum. Studies reporting histologic evidence of healing following periodontal reconstructive therapy were reviewed to determine whether regeneration of these structures improves with increasing healing interval, and whether they regenerate independently or whether regeneration of one structure is dependent upon regeneration of the other. Additionally, the review addresses whether specific reconstructive modalities predictably yield increased amounts of regeneration. Differences in regenerative potential between humans, nonhuman primates, and canines were also examined. Results of over a decade of studies of periodontal reconstructive therapy were tabulated by family (human, nonhuman primate, and canine) …

In Vitro Expression Of Human Zona Pellucida Protein 3, Chih-Wei Chen

Theses and Dissertations in Biomedical Sciences

Human zona pellucida protein 3 (hZP3) is the putative receptor on the zona pellucida of the mature oocyte that recognizes and binds sperm, and therefore plays a critical role in fertilization.

A full length cDNA of hZP3 (1278 bp) was amplified from the human ovary mRNA by reverse transcription-polymerase chain reaction (RT-PCR). The hZP3 cDNA was subcloned into PSK and pREP4 expression vectors. The cDNA of hZP3 was further characterized by restriction mapping, PCR, auto-sequencing and Southern blot analysis by using an internal oligonucleotide probe, and found to be identical to the one reported by J. Dean. Using autosequencing, 289 …

Identification And Characterization Of Mitochondrial Dna Variants In Alzheimer's Disease, Natasha Singh Hamblet

Theses and Dissertations in Biomedical Sciences

Alzheimer's Disease (AD) is a complex neurodegenerative disorder that affects a significant portion of the human population regardless of ethnicity or gender. A mitochondrial hypothesis of AD has been proposed based on a number of studies which establish altered oxidative phosphorylation (OXPHOS) and ATP synthesis in AD tissue. ATP demand is most prevalent in the brain; damage to OXPHOS could severely impair brain metabolism, thereby leading to a decline in cognitive function. Four out of five complexes in the OXPHOS pathway are partly encoded by mitochondrial DNA (mtDNA); thus, this may be a crucial site of lesions that alter brain …

A Tef-1-Independent Mechanism For Activation Of The Simian Virus 40 (Sv40) Late Promoter By Mutant Sv40 Large T Antigens., Paul Casaz, Phillip W. Rice, Charles N. Cole, Ulla Hansen

Dartmouth Scholarship

Simian virus 40 (SV40) large tumor antigen (T antigen) stimulates the activity of the SV40 late promoter and a number of cellular and other viral promoters. We have characterized the ability of T antigens with mutations in the DNA-binding domain and within the N-terminal 85 residues to activate the SV40 late promoter. T antigens lacking both nonspecific and sequence-specific DNA-binding activities were able to induce the late promoter. Mutations within the N-terminal 85 residues of T antigen diminished activation by less than twofold. Activation by wild-type and most of the mutant T antigens required intact binding sites for the cellular …

Ornithine Decarboxylase And Polyamines In Perinatal Hypoxia, Satyaseelan Packianathan

Loma Linda University Electronic Theses, Dissertations & Projects

Hypoxic and hypoxic/ischemic episodes contribute to various neurological aberrations, learning disabilities, et cetera in surviving infants. Despite major advances in understanding the pathophysiology of hypoxia, the cellular basis for hypoxic-mediated injury remains poorly understood. In addition, the role of developmentally essential enzymes vis á vis their contributions, or lack thereof, to hypoxic-mediated injury has not been adequately investigated. In the series of studies comprising this dissertation, we tested the hypothesis that acute and/or chronic hypoxia affect the activity of omithine decarboxylase (ODC; E.C. 4.1.1.17), the developmentally essential enzyme in polyamine biosynthesis, in the fetal and newborn rat brain. Fetal and …

Periodontal Repair In Dogs : Evaluation Of Rhbmp-2 Carriers, Lauralee Nygaard

Loma Linda University Electronic Theses, Dissertations & Projects

This study evaluated candidate carriers for recombinant human bone morphogenic protein-2 (rhBMP-2) in periodontal reconstructive surgery.

Canine demineralized bone matrix (DBM), bovine inorganic crystallene bone matrix (Bio-Oss), bovine derived microfibrillar collagen matrix (Helistat), poly (D,L-lactide-coglycolide) micropaiticles (PLGA), and polylactic acid granules (Drilac) were used with rhBMP-2 (20 (µg/100 µl implant volume) in routine critical size canine supraalveolar periodontal defects. Contralateral defects in six beagle dogs were randomly assigned to receive: DBM/rhBMP-2, DBM-control, Bio-Oss/rhBMP-2, Helistat/rhBMP-2, PLGA/rhBMP-2, or Drilac/rhBMP-2, all with autologous blood except for Helistat and PLGA. Animals were sacrificed eight weeks post-surgery and block sections of the defects were processed …

Modulation Of Neutrophil Functions By Neurotransmitters Implicated In Stress, Chok Ping Wan

Loma Linda University Electronic Theses, Dissertations & Projects

Stress has long been implicated in immune modulation. People under chronic stress have no change in the circulating basal levels of catecholamines while plasma levels of neuropeptide Y (NPY) are significantly increased. Sympathetic nerve fibers with NPY have been found to innervate immune organs. It was hypothesized that NPY might be a mediator in immune modulation in people under chronic stress. Human neutrophils were used as a model to study the effects of NPY alone or together with norepinephrine on the immune system. We now report that NPY modulates oxidative burst (OB) triggered by zymosan in human neutrophils while it …

Regulation Of The Insulin-Like Growth Factor System By Retinoic Acid In Human Osteoblast Cells, Yuehua Zhou

Loma Linda University Electronic Theses, Dissertations & Projects

Retinoic acid (RA) is an important regulator of growth and differentiation in many cell types, including bone. However, its effects on human osteoblast cell growth and differentiation have not been well studied. Therefore, I investigated the effect of RA on proliferation and differentiation of normal human bone cells (HBCs) and human osteosarcoma, SaOS-2 cells. RA decreased baseline as well as serum-stimulated proliferation in normal HBCs. To determine the effect of RA on differentiation, expression of several osteoblastic differentiation markers were studied. RA decreased type I procollagen mRNA levels and l,25(OH)₂D₃-stimulated osteocalcin and alkaline phosphatase (ALP) mRNA …

Experimental Peri-Implant Tissue Breakdown In Rhesus Monkeys, Oliver Hanisch

Loma Linda University Electronic Theses, Dissertations & Projects

The aim of this investigation was to characterize peri-implant tissue breakdown following ligature-induced plaque accumulation around osseointegrated implants in the rhesus monkey. Two hydroxyapatite-coated cylindrical implants were inserted bilaterally in the second premolar and first molar region of both mandible and maxilla in four non-human primates (Macaca mulatto). The implants were left submerged to osseointegrate for one year. Eight weeks after healing abutment connection, a two-month plaque control program was initiated. At the end of this period, clinical and radiographic recordings were carried out, and peri-implant subgingival microbial samples were obtained (baseline). Subsequently, cotton ligatures were placed around …

A Model Of Cytomegalovirus Association With The Development Of Heart Graft Atherosclerosis, Evan Skowronski

Loma Linda University Electronic Theses, Dissertations & Projects

The development of graft atherosclerosis in heart transplant recipients has been associated with the development of post-transplant cytomegalovirus infection. The mechanism of this involvement, however, remains unclear. I undertook a study to determine the role of cytomegalovirus in the development of graft atherosclerosis. First, a rapid method of detecting cytomegalovirus based on capillary polymerase chain reaction and gel electrophoresis was employed to determine the presence of cytomegalovirus in a wide variety of clinical samples. Detection of cytomegalovirus is a lengthy procedure under normal conditions, and timely detection of cytomegalovirus in transplant recipients may allow intervention early enough to block the …

Heterozygosity Mapping Of Partially Congenic Lines: Mapping Of A Semidominant Neurological Mutation, Wheels ( Whl), On Mouse Chromosome 4, Patrick M. Nolan, Patricia J. Sollars, Barbara A. Bohne, Warren J. Ewens, Gary E. Pickard, Maja Bucan

School of Veterinary and Biomedical Sciences: Faculty Publications

We identified a semidominant, chemically induced, mouse use mutation with a complex array of abnormal behaviors including bidirectional circling and hyperactivity, abnormal circadian rhythmicity and abnormal responses to light. In this report, we genetically and phenotypically characterized the circling/ waltzing component of the abnormal behavior. We mapped the locus controlling this trait by heterozygosity mapping of partially congenic lines carrying the mutagenized chromosome outcrossed to different inbred strains for three generations. Analysis of 68 PCR-based markers in 13 affected individuals indicated that the mutant locus, named Wheels (Whl), resides in the subcentromeric portion of mouse chromosome 4. The …

The Nutritional Knowledge, Food Choices, And Exercise Habits Of Students At Langston University, Preston Solomon

McCabe Thesis Collection

The nutritional knowledge, food choice, and exercise habits of an individual determine his or her overall health and life expectancy. Information on these topics enables nutrition educators to develop strategies to improve knowledge and to tailor educational efforts which affect a large number of persons. Poor health in America today is an ever present reality. Heart disease, cancer, diabetes mellitus, cerebrovascular diseases, renal diseases, and pulmonary diseases are causes of death related in part to lack of nutritional knowledge and poor eating and exercise habits. A few of these diseases are chronic in nature and are the most deadly.

Moraxella (Branhamella) Catarrhalis: A Molecular Epidemiology Study, Lyndell R. Gill

Electronic Theses and Dissertations

Moraxella (Branhamella) catarrhalis is the third-most-frequently isolated microorganism associated with acute exacerbations of chronic bronchitis in patients during their stay at the Mountain Home VA Medical Center (MHVAMC). In order to develop a practical, epidemiologically-meaningful typing method for M. (B.) catarrhalis, we tested two methods based on analysis of chromosomal DNA for typeability, reproducibility, and ability to differentiate between unrelated strains (discriminatory power, D). M. (B.) catarrhalis isolants from MHVAMC from 7/1/87-6/30/88 were grown overnight in broth and embedded in agarose. DNA was isolated by standard methods. The DNA was subjected to: (1) restriction endonuclease digestion (with either Bgl II …
