Direct Demonstration Of Retroviral Recombination In A Rhesus Monkey, Dawn P. Wooley, Randall A. Smith, Susan Czajak, Ronald C. Desrosiers

Neuroscience, Cell Biology & Physiology Faculty Publications

Recombination may be an important mechanism for increasing variation in retroviral populations. Retroviral recombination has been demonstrated in tissue culture systems by artificially creating doubly infected cells. Evidence for retroviral recombination in vivo is indirect and is based principally on the identification of apparently mosaic human immunodeficiency virus type 1 genomes from phylogenetic analyses of viral sequences. We infected a rhesus monkey with two different molecularly cloned strains of simian immunodeficiency virus. One strain of virus had a deletion in vpx and vpr, and the other strain had a deletion in nef. Each strain on its own induced low virus …

A Cytochemical Evaluation Of Blood-Brain Barrier Sodium, Potassium- And Calcium-Adenosine Triphosphatase Polarity, Panya Steve Manoonkitiwongsa

Loma Linda University Electronic Theses, Dissertations & Projects

The blood-brain barrier (BBB) is formed by cerebral vascular endothelial cells. Brain ion and fluid homeotasis essential for proper neural functioning is due to the BBB. Sodium-potassium and calcium-activated adenosine triphosphatase (Na⁺, K⁺-ATPase and Ca²⁺-ATPase) serve as one of the main mechanisms controlling brain Na⁺, K⁺, and Ca²⁺ concentrations. The present accepted concept is that both of these enzymes are localized to the abluminal plasma membrane of endothelial cells although there have been contrary results from some studies. Because of these discrepancies, further work was needed. Various cytochemical procedures …

The Effect Of Systemic Doxycycline On Alveolar Bone Loss Following Periradicular Surgery, G. Reed Cummings

Loma Linda University Electronic Theses, Dissertations & Projects

Studies have shown an average of 0.5 mm to over 1.0 mm of bone loss following full thickness flap reflection. Recent investigations have revealed that the tetracycline family of antibiotics can prevent bone loss. The purpose of this study was to determine the effect of systemic Doxycycline on crestal alveolar bone loss following periradicular surgery in Beagle dogs.

The experiment was divided into two phases. The first phase served as the control (Non-Doxycycline), the second phase as the experiment (Doxycycline). Full thickness flaps were reflected in the mandibular left or right quadrant (control side) of five Beagle dogs. Using a …

The Effect Of Root End Demineralization On Cementogenesis : A Long Term Investigation, Hamid R. Abedi

Loma Linda University Electronic Theses, Dissertations & Projects

Craig and Harrison¹² examined the effect of demineralization of resected root ends on wound healing following periradicular surgery. Based on its microscopic evaluations from 4-45 days, it was proposed that demineralization of resected root ends enhances cementogenesis. The purpose of this study was to investigate the longer term effects of demineralization on cementogenesis using Mineral Trioxide Aggregate (MTA) or amalgam as root end filling materials. After completion of root canal therapy and endodontic surgery on seventy-two roots of mandibular second, third and fourth premolars of six beagle dogs, 32/72 of the root ends at random were etched with 50% …

A Dichotomous Role For Nitric Oxide During Acute Toxoplasma Gondii Infection In Mice, Imtiaz A. Khan, Joseph D. Schwartzman, Tadashi Matsuura, Lloyd H. Kasper

Dartmouth Scholarship

Production of nitric oxide by macrophages is believed to be an important microbicidal mechanism for a variety of intracellular pathogens, including Toxoplasma gondii. Mice with a targeted disruption of the inducible nitric oxide synthase gene (iNOS) were infected orally with T. gondii tissue cysts. Time to death was prolonged compared with parental controls. Histologic analysis of tissue from infected mice showed scattered small foci of inflammation with parasites in various tissues of iNOS−/− mice, whereas tissue from the parental C57BL/6 mice had more extensive tissue inflammation with few visible parasites. In particular, extensive ulceration and necrosis of distal small …

Perceived Differences Between Male And Female Occupational Therapists’ Treatment And Other Related Gender Issues, Dennis Robert Jones

This study explored how occupational therapy clients perceive the treatment they receive from male and female occupational therapists. The study was conducted in a qualitative manner. Occupational therapy supervisors who have supervised both female and male occupational therapists were interviewed to gain an initial understanding of the relevant issues. More structured interviews were then conducted with clients who have been treated by both a female and a male occupational therapist. Therapists and clients were also observed during four treatment sessions.

Analysis of the data collected through interviews revealed that supervisors and clients do notice some behavioral differences in male and …

Comparison Of Beta-Adrenoceptor Coupled Camp Production In Cultured Human Mononuclear Leukocytes And Myometrial Cells, Yu-Li Liu

Electronic Theses and Dissertations

$\beta\sb2$-Adrenoceptor ($\beta\sb2$-AR) agonists, such as terbutaline, are used as tocolytic agents in the treatment of preterm labor. $\beta$-Adrenoceptor stimulation relaxes myometrium through specific receptors coupled through Gs to adenylyl cyclase (AC) that catalyzes the conversion of ATP to cAMP. The purpose of this study was to compare $\beta$-adrenoceptors and cAMP production in cultured human leukocytes and myometrial cells, and to determine the importance of $\beta$-adrenoceptors and cAMP production in isoproterenol-induced myometrial relaxation. $\sp{125}$I-iodopindolol was used to assess $\beta$-adrenoceptor affinity and number cAMP levels were analyzed before and after stimulation by isoproterenol, AlF$\sb4\sp-$, forskolin, and PGE$\sb1$. Isometric recording was used to …

Murine Transporter Associated With Antigen Presentation (Tap) Preferences Influence Class I-Restricted T Cell Responses., A J Yellen-Shaw, C E Laughlin, R M Metrione, Laurence C. Eisenlohr

Department of Biochemistry and Molecular Biology Faculty Papers

The transporter associated with antigen presentation (TAP) complex shuttles cytosolic peptides into the exocytic compartment for association with nascent major histocompatibility complex class I molecules. Biochemical studies of murine and human TAP have established that substrate length and COOH-terminal residue identity are strong determinants of transport efficiency. However, the existence of these specificities in the intact cell and their influences on T cell responses have not been demonstrated. We have devised a method for studying TAP- mediated transport in intact cells, using T cell activation as a readout. The approach makes use of a panel of recombinant vaccinia viruses expressing …

The General Well-Being Of Recreational Drug Users: A Sub-Analysis Of The Drugnet Survey, Jennifer Reneau

Masters Theses & Specialist Projects

Triazine Herbicide Exposure And Breast Cancer Incidence: An Ecologic Study Of Kentucky Counties, Michele A. Kettles, Steven R. Browning, Timothy Scott Prince, Sanford W. Horstman

Preventive Medicine and Environmental Health Faculty Publications

The incidence of breast cancer in the United States has steadily increased for the past three decades. Exposure to excess estrogen, in both natural and synthetic forms, has been implicated as a risk factor for the development of this disease. Considerable interest has been focused on organochlorines, such as the triazine herbicides, and their possible role in the initiation or promotion of human breast cancer. To explore this relationship, an ecologic study of Kentucky counties was designed. Exposure to triazines was estimated by use of water contamination data, corn crop production, and pesticide use data. A summary index of triazine …

Modulation Of The Rat Potassium Channel Kv1.5, Daniel Benjamin Saal

Yale Medicine Thesis Digital Library

1. Kv1.5 is a delayed rectifier-type potassium channel. We have examined the localization of the channel protein using a polyclonal antibody against Kv1.5. This channel is expressed in numerous regions of the brain, primarily in glial cells. Its expression is particularly intense in the endfoot processes which abut the microvasculature of the brain. It is also expressed in the cell bodies and cellular processes in the pituitary.2. Immunoprecipitation of the Kv1.5 protein, from HEK 293 cells which were transformed with the Kv1.5 gene, revealed that the channel is phosphorylated and that treatment of cells with dibutyryl cyclic AMP (dibcAMP) or …

Role Of Egr-1 Gene Expression In B Cell Receptor-Induced Apoptosis In An Immature B Cell Lymphoma, Subramanian Muthukkumar, Seong-Su Han, Sumathi Muthukkumar, Vivek M. Rangnekar, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Ligation of B cell receptor (BCR) on BKS-2, an immature B cell lymphoma by anti-IgM antibodies (Ab) caused apoptosis. Here we report that signaling through B cell receptor in wild type BKS-2 cells down-regulated the expression of Egr-1, a zinc finger-containing transcription factor. A reduction in the level ofEgr-1 mRNA could be demonstrated as early as 30 min after the ligation of BCR on BKS-2 cells. Immunocytochemical and Western blot analysis revealed that the expression of EGR-1 protein was also inhibited by anti-IgM treatment. Antisense oligonucleotides to Egr-1 caused growth inhibition and apoptosis in BKS-2 cells, suggesting that …

Right Medial Temporal-Lobe Contribution To Object-Location Memory, B Milner, Ingrid Johnsrude, J Crane

Brain and Mind Institute Researchers' Publications

An important aspect of normal human memory, and one humans share with many other species, is the ability to remember the location of objects in their environment. There is by now strong evidence from the study of epileptic patients undergoing brain surgery that right temporal-lobe lesions that encroach extensively upon the hippocampal and parahippocampal gyrus impair the delayed, but not the immediate, recall of the location of objects within a random array. These findings have now been extended to a multiple-trial, spatial-array learning task; by including not only patients tested after unilateral anterior temporal lobectomy but also those with a …

Detection And Characterization Of Sp1 Binding Activity In Human Chondrocytes And Its Alterations During Chondrocyte Dedifferentiation., Rita M. Dharmavaram, Gang Liu, Sheryl D. Mowers, Sergio A. Jimenez

Department of Medicine Faculty Papers

We have detected DNA binding activity for a synthetic oligonucleotide containing an Sp1 consensus sequence in nuclear extracts from human chondrocytes. Changes in the levels of Sp1 oligonucleotide binding activity were examined in nuclear extracts from freshly isolated human chondrocytes, from chondrocytes that had been cultured under conditions that allowed the maintenance of a chondrocyte-specific phenotype on plastic dishes coated with the hydrogel poly(2-hydroxyethyl methacrylate), and from chondrocytes induced to dedifferentiate into fibroblast-like cells by passage in monolayer culture on plastic substrata. It was observed that Sp1 binding was 2-3-fold greater in nuclear extracts from dedifferentiated chondrocytes than in nuclear …

Identification Of Mycobacterium Paratuberculosis Gene Expression Signals, John P. Bannantine, Raul G. Barletta, Charles O. Thoen, Robert E. Andrews Jr.

School of Veterinary and Biomedical Sciences: Faculty Publications

Mycobacterium paratuberculosis promoter-containing clones were isolated from a genomic DNA library constructed in the transcriptional-translational fusion vector pYUB76. The promoter-containing DNA fragments were identified in the surrogate host Mycobacterium smegmatis by expression of the promoterless lacZ reporter gene of pYUB76. The expression signals exhibited a wide range of strengths, as indicated by their corresponding β-galactosidase activities. Eight clones were sequenced and characterized further. Predicted open reading frames and codon usage were identified by computer analysis. Database searching for related sequences using the BLAST method revealed no homologies. Transcriptional activity was measured by slot-blot hybridization with steady-state RNA isolated from lacZ …

The Effects Of Divorce And Custody Arrangements On Children’S Behavior, Development, And Adjustment, Michael E. Lamb, Kathleen J. Sternberg, Ross A. Thompson

Department of Psychology: Faculty Publications

This article summarizes the consensus among a group of experts from developmental and clinical psychology, sociology, social welfare, and law who sought to evaluate existing empirical evidence regarding the ways in which children are affected by divorce and the varying custody arrangements that follow it. Divorce and/or single parenthood tend to have adverse effects on children’s adjustment, with the magnitude of the effects varying depending on the psychological status of the two parents, the extent of conflict between them, and the financial circumstances, particularly after divorce. Children whose nonresidential parents continue to support them financially, those whose custodial parents are …
