A Thyroid Hormone-Regulated Gene In Xenopus Laevis Encodes A Type Iii Iodothyronine 5-Deiodinase., Donald L. St Germain, Robert Schwartzman, Walburga Croteau, Akira Kanamori, Zhou Wang, Donald D. Brown, Valerie Galton

Dartmouth Scholarship

The type III iodothyronine 5-deiodinase metabolizes thyroxine and 3,5,3'-triiodothyronine to inactive metabolites by catalyzing the removal of iodine from the inner ring. The enzyme is expressed in a tissue-specific pattern during particular stages of development in amphibia, birds, and mammals. Recently, a PCR-based subtractive hybridization technique has been used to isolate cDNAs prepared from Xenopus laevis tadpole tail mRNA that represent genes upregulated by thyroid hormone during metamorphosis. Sequence analysis of one of these cDNAs (XL-15) revealed regions of homology to the mRNA encoding the rat type I (outer ring) 5'-deiodinase, including a conserved UGA codon that encodes selenocysteine in …

Short And Long Term Effects Of Proton Microbeam Irradiation : In The Lateral Geniculate Nucleus Of Felis Domesticus, Chad Sherwood Reder

Loma Linda University Electronic Theses, Dissertations & Projects

Little is known of the effects of proton irradiation on neural tissue. A 1.0 mm microbeam was used on the cat lateral geniculate nucleus (LGN) to quantify the short term (< 3 months) and long term (< 9 months) effects of radiation damage. The LGN is a large structure with well defined afferent, efferent, and receptive field properties.

Electrophysiological and histological techniques were used to examine the effects of the microbeam at 60, 40, and 16 Gy, administered as a single bolus. Recordings of light evoked responses in the LGN were obtained using microelectrodes in nine animals within 12 weeks of irradiation, and 6 animals within 36 weeks of irradiation. Receptive fields were mapped onto a tangent screen using standard receptive field techniques. Histological measures included afferent …

Stab Wounds To Rat Brains : Demyelination, Remyelination And The Cellular Response, Particularly Of Oligodendrocytes, Xie Dangci

Loma Linda University Electronic Theses, Dissertations & Projects

The present body of knowledge concerning the results of central nervous system injury is incomplete and controversial. The role of oligodendrocytes, the cells involved in phagocytosis, the stages of demyelination, and the evidence for remyelination are of interest. Following stab wounds to rat brain cortex, corpus callosum and hippocampus, the animals were examined at 4,7,11,18,23,29,45,60 and 70 days postoperation (dpo). To help in the identification of cells immunocytochemical markers for astrocytes and immature oligodendrocytes were used. These were labels for glial fibrillary acidic protein (GFAP) and myelin/oligodendrocyte specific protein (MOSP) respectively. Light and electron microscopy were correlated using conventionally prepared …

Polyclonal Infections Due To Mycobacterium Avium Complex In Patients With Aids Detected By Pulsed-Field Gel Electrophoresis Of Sequential Clinical Isolates., Alexander M. Slutsky, Robert D. Arbeit, Thomas W. Barber, Josiah Rich, C Fordham Von Reyn

Dartmouth Scholarship

Invasive infection with organisms of the Mycobacterium avium complex (MAC) is common among patients with advanced human immunodeficiency virus infection. In previous studies, we analyzed multiple individual colonies of MAC isolated from specimens obtained at the same time and observed that 14 to 20% of patients are simultaneously infected with more than one strain. In this study, we examined sequential isolates from 12 patients with AIDS who had two or more MAC isolates available from clinical specimens collected more than 1 week apart; the intervals between the first and last specimens ranged from 8 to 192 (median, 46) days. For …

Prevalence Of Fatty Liver In Japanese Children Ages 4 To 12 Years Old : Relationship To Obesity : An Epidemiological Ultrasonographic Survey, Kunihiko Tominaga

Loma Linda University Electronic Theses, Dissertations & Projects

The prevalence of fatty liver disease in children is not well established and its relationship to childhood obesity is poorly defined. The present study of 810 northern Japanese school-aged children (4-12 years old), determined the prevalence of fatty liver and its relationship to gender and degree of obesity. Diagnosis of fatty liver was assessed by real-time ultrasonography.

RESULTS: 1. The overall prevalence of fatty liver is 2.6 %. 2. Fatty liver prevalence is higher for boys (3.4 %) than for girls (1.8 %), although not statistically significant (P = 0.15). 3. Fatty liver occurs in children as young as 6 …

Immunohistochemical Estrogen Receptor Determination In Human Breast Carcinoma: Correlation With Histologic Differentiation And Age Of The Patients, Shahid Pervez, S. Shaikh, F. Aijaz, S. A. Aziz, M. Naqvi, Sheema H. Hasan

Department of Pathology and Laboratory Medicine

An immunohistochemical assay for the measurement of estrogen receptor (ER) has been evaluated on 290 consecutive human breast biopsy and mastectomy specimens in the year 1992 at The Aga Khan University Hospital laboratories. Immunohistochemical localization of estrogen receptor on frozen/paraffin section was scored in a semi-quantitative fashion incorporating both the intensity and the distribution of specific staining. Histologic grading of the tumour was performed according to Bloom’s method. In this study, 21% of the tumours were estrogen receptor negative, 15% were weak positive, 25% intermediate positive and 39% strong positive. Fifty percent of the well differentiated tumours showed strong ER …

Patients As Subjects For Research: Ethical Dilemmas For The Primary Care Clinician-Investigator, Susan F. Slatkoff, Peter Curtis, Ann L. Coker

CRVAW Faculty Journal Articles

Background: Past studies suggested an association between human papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN). In 1987, University of North Carolina (UNC) Hospitals Family Practice Center clinicians were approached for a control population to study this association. Methods: One hundred fives patients attending the UNC Hospitals Neoplasia Clinic with biopsy-proven CIN 2 or 3 and 268 control patients attending the UNC Family Practice Center for a routine Papanicolaou smear were enrolled in this case-control study. Case and control patients consented to having an additional cervical specimen taken and to being interviewed. The cervical specimens were classified by the Southern blot …

Interleukin-12 Enhances Murine Survival Against Acute Toxoplasmosis., Imtiaz A. Khan, Tadashi Matsuura, Lloyd H. Kasper

Dartmouth Scholarship

Protective immunity against Toxoplasma gondii is mediated by the host cellular immune response. Interleukin-12 (IL-12), a recently described cytokine that stimulates NK cells to produce gamma interferon (IFN-gamma), is able to enhance host protection against this parasite in SCID mice. Administration of IL-12 to A/J mice significantly increased survival over that of control mice when IL-12 was delivered early in the course of acute infection. If it was administered at day 3 or thereafter, there was no observed difference in mortality between treated and control mice. Antibody depletion of IL-12 increased susceptibility to infection, as measured by mortality, only when …

Functional Analysis Of Human Alpha 1(I) Procollagen Gene Promoter. Differential Activity In Collagen-Producing And -Nonproducing Cells And Response To Transforming Growth Factor Beta 1., Sergio A. Jimenez, John A. Varga, Anne Olsen, Liye Li, Arturo Diaz, Janet Herhal, Julie Koch

Department of Medicine Faculty Papers

To gain a further understanding of the regulation of human type I collagen gene expression under physiologic and pathologic conditions, we characterized 5.3 kilobase pairs (kb) of the human alpha 1(I) procollagen gene promoter. A series of deletion constructs containing portions of the alpha 1(I) procollagen 5'-flanking region (with end points from -5.3 kb to -84 base pairs (bp)) ligated to the chloramphenicol acetyltransferase (CAT) reporter gene were transiently transfected into NIH/3T3 cells. Maximal CAT activity was observed with constructs having 5' end points from -804 to -174 bp. A further 5' deletion to -84 bp caused a marked reduction …

Elevated Expression Of Type Vii Collagen In The Skin Of Patients With Systemic Sclerosis. Regulation By Transforming Growth Factor-Beta., Lidia Rudnicka, John Varga, Angela M. Christiano, Renato V. Iozzo, Sergio A. Jimenez, Jouni Uitto

Department of Dermatology and Cutaneous Biology Faculty Papers

A hallmark of systemic sclerosis (SSc) is the development of tissue fibrosis. Excessive production of several connective tissue components normally present in the dermis, including type I, III, V, and VI collagens as well as fibronectin and proteoglycans, is a consistent finding in the skin of SSc patients. Type VII collagen is a major constituent of anchoring fibrils, present in the skin at the dermal-epidermal basement membrane zone. TGF-beta has been shown to upregulate the expression of the type VII collagen gene. In this study, we assessed the expression of type VII collagen and TGF-beta in the skin of patients …

Immunologic Evaluation Of Ectopic Gestation, Tawfig Amin Nasser

Health Services Research Dissertations

Ectopic gestation is an error in the implantation site of the blastocyst. Extrauterine implantation presents a unique environment since the protective features of the uterus are absent. This study is an investigation into the immunoregulatory differences that may develop as a result of a change in the feto-maternal junction.

The effects of female plasma on one-way mixed lymphocyte cultures and mitogen-stimulated cultures, anti-paternal lymphocytotoxicity, and lymphocyte phenotypes were determined on normal, ectopic and non-pregnant females. The results indicated that pregnant female plasma enhanced the response of autologous lymphocytes to spouse and male control lymphocytes. Enhancement was not seen in the …

Social Security Reform: A Budget Neutral Approach To Reducing Older Women's Disproportional Risk Of Poverty, Richard V. Burkhauser, Timothy M. Smeeding

Center for Policy Research

Perhaps the single greatest achievement of social policy in the United States over the last three decades has been reducing poverty in old age. The transition from work to retirement is no longer economically perilous for the vast majority of older American workers. For most married couples, the risk of falling into poverty even several years after retirement is small. But when one partner of the marriage dies, the survivor faces another much more risky economic transition. The single greatest risk of falling into poverty in old age now comes after the death of a spouse, as the survivor faces …

Basic Fibroblast Growth Factor And Fibroblast Growth Factor Receptor I Are Implicated In The Growth Of Human Astrocytomas., R S Morrison, F Yamaguchi, H Saya, J M Bruner, Alan M. Yahanda Md, Facs, L A Donehower, M Berger

PCI Publications and Projects

Malignant astrocytomas are highly invasive, vascular neoplasms that comprise the majority of nervous system tumors in humans. A strong association has previously been made between malignancy in human astrocytic tumors and increased expression of certain fibroblast growth factor (FGF) family members, including basic and acidic FGF. The influence of endogenous basic FGF on glioblastoma cell growth in vitro was evaluated using basic FGF-specific antisense oligonucleotides. These studies indicated that human glioblastoma cell growth in vitro, can be inhibited by suppressing basic FGF expression. Human astrocytomas also exhibited changes in FGF receptor (FGFR) expression during the course of their progression from …

Bacteriuria And Pregnancy Outcome: A Prospective Hospital-Based Study In Pakistani Women, Rahat Qureshi, Khalid S. Khan, Omar Darr, Nasir Khattak, Javaid H. Rizvi, Bader J. Farooqui

Department of Obstetrics & Gynaecology

The prevalence of bacteriuria in Pakistani women and its association with complications of pregnancy was studied. Out of 1579 women, 77 had bacteriuria (4.8%). There was no association of age, gravidity, parity, haemoglobin, pre-eclampsia, mode of delivery, gestational age at delivery, preterm delivery and low birth-weight with presence of bacteriuria. With detection and treatment the pregnancy outcome of women with bacteriuria in pregnancy was the same as that of those without
