Stimulation Of Alpha 1(I) Procollagen Gene Expression In Nih-3t3 Cells By The Human T Cell Leukemia Virus Type 1 (Htlv-1) Tax Gene., E. Munoz, D. Suri, S. Amini, K. Khalili, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

The mechanisms that regulate the expression of genes encoding extracellular matrix proteins in fibroblasts and other mesenchymal cells have remained elusive. Studies from several laboratories have indicated that Tax, a trans-regulatory protein from the human T cell leukemia virus type I not only augments viral gene expression but also triggers the expression of various cellular genes. Here, we examined the hypothesis that the expression of collagen genes may also be modulated by Tax. NIH-3T3 cells were simultaneously transfected with a Tax expressor plasmid and a chimeric construct containing regulatory sequences (-804 to +42 bp) of the alpha 1(I) procollagen gene …

An Audit On Hospital Management Of Bronchial Asthma, J A. Khan, S Saghir, G Tabassum, S F. Husain

Section of Pulmonary & Critical Care

Medical audit is a new concept in developing countries like Pakistan. We carried out this retrospective study on bronchial asthma. The purpose was to see if care given to patient with asthma meets the accepted international standard or not. During this audit several deficiencies were found. Documentation in notes about signs indicating severity of asthma was very poor. Peak flow recording in the notes was also very deficient. There was no documentation in notes whether inhalers technique of the patients has been checked or not. This audit shows that care given to asthma patients is far from satisfactory and we …

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.

Survival Of Immunoglobulin G-Opsonized Toxoplasma Gondii In Nonadherent Human Monocytes., Camilo E. Fadul, Jacqueline Y. Channon, Lloyd H. Kasper

Dartmouth Scholarship

Toxoplasma gondii is a protozoan parasite that is able to penetrate human monocytes by either passive uptake during phagocytosis or active penetration. It is expected that immunoglobulin G (IgG) opsonization will target the parasite to macrophage Fc gamma receptors for phagocytic processing and subsequent degradation. Antibody-opsonized T. gondii tachyzoites were used to infect nonadherent and adherent human monocytes obtained from the peripheral blood of seronegative individuals. The infected monocytes were evaluated for the presence of intracellular parasites and the degree of parasiticidal activity. A marked difference in both the numbers of infected macrophages and numbers of parasites per 100 macrophages …

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 …

Expression Of Genes Encoding Antioxidant Enzymes In Preimplantation Mouse And Cow Embryos And Primary Bovine Oviduct Cultures Employed For Embryo Coculture., M B Harvey, M Y Arcellana-Panlilio, X Zhang, G A Schultz, A J Watson

Obstetrics & Gynaecology Publications

Preimplantation embryos from a variety of mammalian species contrast markedly in their response to culture in vitro. Murine preimplantation embryos display a wider tolerance than other mammalian species to culture environments, and this has contributed to the development of several effective defined culture media. Embryo coculture on somatic cells remains the most effective method of supporting reasonable rates of bovine preimplantation development in vitro. The patterns of gene expression for several antioxidant enzymes during preimplantation murine and bovine development were examined by use of the reverse transcription-polymerase chain reaction technique to determine whether the differential developmental capacity of mammalian preimplantation …

Evaluation Of Oral Midazolam As Pre-Medication In Day Care Surgery In Adult Pakistani Patients, N Ahmed, F A. Khan

Department of Anaesthesia

A placebo controlled randomized double blind study was designed to assess the suitability of oral Midazolam as a premedication in day care surgery in adult Pakistani patients. Fifty ASA I and II patients aged between 20-60 years received either Midazolam 7.5 mg or a placebo approximately one hour prior to surgery. Midazolam 7.5 mg produced significant anxiolysis and sedation (p < 0.001) in comparison to placebo after one hour of premedication. There was a significant difference (p < 0.001) in the mean heart rate and blood pressure in both groups after 1 hour of premedication with a lesser rise in blood pressure and heart rate in the Midazolam group. Psychomotor performance assessed by 'n' deletion test was impaired by Midazolam (p < 0.001) and recall of pictures revealed differences (p < 0.05) in the groups at one hour after premedication. However, at four hours after surgery there were no differences in both groups. These findings indicate that rapidly acting oral Midazolam in doses of 7.5 mg provided safe and effective premedication in terms of anxiolysis, sedation, amnesia and psychomotor performance and is suitable for day surgery.

The Health Belief Model As A Predictor Of Gynecological Exams: Does Sexual Orientation Matter?, Lynn Elizabeth Kunkel

Dissertations and Theses

Screening and early detection are essential for the management and control of most diseases. It is important for women to practice routine health care that includes both clinical and self examinations. Today, many women go without health care due to barriers which prevent them from obtaining adequate care. The present study was designed to investigate, using the Health Belief Model, whether there is a difference between heterosexual and lesbian women in obtaining gynecological exams. Responses from 238 participants, 70 heterosexuals and 168 lesbians, indicated that the Health Belief Model was a significant predictor of whether women complied with recommended guidelines …

Audit Changes Clinical Practice! Impact On Rate Of Justification Of Hysterectomy Indication, Khalid S. Khan, J H. Rizvi

Department of Obstetrics & Gynaecology

After performing a baseline audit in 1986-89, an ongoing quality assurance process was initiated in January, 1990 and all hysterectomies performed over the next 2 year period were analyzed. Hysterectomy indications were divided into two groups: one in which the uterine specimen was expected to show pathology and another in which no pathology was expected. The hysterectomy was considered justified in the former if the pathology report verified the indication or showed a significant alternate pathology. In the latter, validation criteria showing documentation of certain prerequisite diagnostic procedures performed before reverting to hysterectomy, were used to ascertain justification. The overall …

Identification Of An Idiotypic Peptide Recognized By Autoantibodies In Human Immunodeficiency Virus-1-Infected Individuals, Q. L. Wang, H.-T. Wang, Edwin Blalock, Sybille Müller, Heinz Köhler

Markey Cancer Center Faculty Publications

Antibodies against HIV-1 proteins in HIV-1-infected individuals share a cross-reactive idiotype defined by the monoclonal antiidiotypic antibody 1F7 (5). Using a computer algorithm based on the molecular recognition theory, regions of inverse hydropathy between the variable sequence of 1F7 and human monoclonal anti-HIV-1 antibodies were identified, which are assumed to be involved in idiotype-antiidiotype contacts. A peptide was designed from the proposed contact in the variable heavy chain framework 3-complementarity determining region 3 (FR3-CDR3) of human antibodies and was synthesized. This peptide is recognized by the antiidiotype 1F7 and inhibits the binding of 1F7 to human anti-HIV-1 antibodies which express …

Astrocytes Derived From P53-Deficient Mice Provide A Multistep In Vitro Model For Development Of Malignant Gliomas., Alan M. Yahanda Md, Facs, J M Bruner, L A Donehower, R S Morrison

PCI Publications and Projects

Loss or mutation of p53 is thought to be an early event in the malignant transformation of many human astrocytic tumors. To better understand the role of p53 in their growth and transformation, we developed a model employing cultured neonatal astrocytes derived from mice deficient in one (p53 +/-) or both (p53 -/-) p53 alleles, comparing them with wild-type (p53 +/+) cells. Studies of in vitro and in vivo growth and transformation were performed, and flow cytometry and karyotyping were used to correlate changes in growth with genomic instability. Early-passage (EP) p53 -/- astrocytes achieved higher saturation densities and had …

Constitutive Alzheimer's-Type Tau Epitopes In A Neuritogenic Rat Cns Cell Line, Mary P. Lambert, Shasta Sabo, Chi Zhang, S. Ather Enam, William L. Klein

Section of Neurosurgery

Paired helical filaments (PHFs) of Alzheimer's disease (AD) largely comprise hyperphosphorylated forms of the cytoskeletal protein tau. AD-type tau phosphoepitopes, detected by various monoclonal antibodies, are absent from normal adult neurons, but recent studies have shown that their expression may contribute to neuritogenesis and axon differentiation in the developing nervous system. Therefore, we have examined a brain nerve cell line that is spontaneously neuritogenic for possible expression of AD-type tau epitopes. The neuritogenic rat brain cell line B103 was found to constitutively produce two AD-related epitopes of tau, detected by cellular immunofluorescence studies with the PHF-1 and Alz-50 monoclonal antibodies. …

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 …

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 …

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 …

Immune Response To The Carcinoembryonic Antigen In Patients Treated With An Anti-Idiotype Antibody Vaccine, Kenneth A. Foon, Mala Chakraborty, William J. John, Amanda Sherratt, Heinz Köhler, Malaya Bhattacharya-Chatterjee

Markey Cancer Center Faculty Publications

We have generated an IgG1 murine monoclonal anti-idiotype antibody (Ab2) designated 3H1, which mimics a specific epitope on the carcinoembryonic antigen (CEA). Patients with CEA positive tumors are immunologically "tolerant" to CEA. We used 3H1 as a surrogate for CEA for vaccine therapy of 12 patients with advanced colorectal cancer. Each of the patients received a minimum of four intracutaneous injections of aluminum hydroxide precipitated 3H1 at either 1, 2, or 4 mg dosage per injection. 9 of 12 patients demonstrated anti-anti-idiotypic (Ab3) response to 3H1. All nine patients generated specific anti-CEA antibody demonstrated by reactivity with radiolabeled purified CEA; …
