The Type 2 Iodothyronine Deiodinase Is Expressed Primarily In Glial Cells In The Neonatal Rat Brain, Ana Guadaño-Ferraz, Maria Jesus Obregón, Donald L. St. Germain, Juan Bernal Sep 1997

The Type 2 Iodothyronine Deiodinase Is Expressed Primarily In Glial Cells In The Neonatal Rat Brain, Ana Guadaño-Ferraz, Maria Jesus Obregón, Donald L. St. Germain, Juan Bernal

Dartmouth Scholarship

Thyroid hormone plays an essential role in mammalian brain maturation and function, in large part by regulating the expression of specific neuronal genes. In this tissue, the type 2 deiodinase (D2) appears to be essential for providing adequate levels of the active thyroid hormone 3,5,3′-triiodothyronine (T3) during the developmental period. We have studied the regional and cellular localization of D2 mRNA in the brain of 15-day-old neonatal rats. D2 is expressed in the cerebral cortex, olfactory bulb, hippocampus, caudate, thalamus, hypothalamus, and cerebellum and was absent from the white matter. At the cellular level, D2 is expressed predominantly, if not …

Ultrastructure Of The May-Hegglin Anomaly, T Siddiqui Sep 1997

Ultrastructure Of The May-Hegglin Anomaly, T Siddiqui

Section of Internal Medicine

Ultrastructural features of the leucocytes in two patients suffering from the May-Hegglin anomaly were studied using electron microscopy. In both the cases, electron dense material parallel to the long axis of the inclusions were noted. Platelet ultrastructure was normal. A review of the literature indicates that the May-Hegglin anomaly is a heterogeneous condition both ultrastructurally and clinically.


A Novel Polymorphism Of Fcgammariiia (Cd16) Alters Receptor Function And Predisposes To Autoimmune Disease, Jianming Wu, Jeffrey C. Edberg, Patricia B. Redecha, Vipin Bansal, Paul M. Guyre, Kimberly Coleman, Jane E. Salmon, Robert P. Kimberly Sep 1997

A Novel Polymorphism Of Fcgammariiia (Cd16) Alters Receptor Function And Predisposes To Autoimmune Disease, Jianming Wu, Jeffrey C. Edberg, Patricia B. Redecha, Vipin Bansal, Paul M. Guyre, Kimberly Coleman, Jane E. Salmon, Robert P. Kimberly

Dartmouth Scholarship

A novel polymorphism in the extracellular domain 2 (EC2) of FcgammaRIIIA affects ligand binding by natural killer (NK) cells and monocytes from genotyped homozygous normal donors independently of receptor expression. The nonconservative T to G substitution at nucleotide 559 predicts a change of phenylalanine (F) to valine (V) at amino acid position 176. Compared with F/F homozygotes, FcgammaRIIIa expressed on NK cells and monocytes in V/V homozygotes bound more IgG1 and IgG3 despite identical levels of receptor expression. In response to a standard aggregated human IgG stimulus, FcgammaRIIIa engagement on NK cells from V/V (high-binding) homozygotes led to a larger …

OBJECTIVES: This study examines the impact of the condom availability program in New York City public high schools by comparing rates of sexual activity and condom use for New York students and similar students in Chicago. METHODS: A total of 7119 students from 12 randomly selected New York schools and 5738 students from 10 Chicago schools participated in a cross-sectional survey. RESULTS: New York students, compared with Chicago students, reported equal rates of sexual activity but higher rates of condom use at last intercourse (odds ratio [OR] = 1.36). For higher-risk students (those with three or more sexual partners in …


Recommendations For Elimination Of Bovine Tuberculosis In Free-Ranging White-Tailed Deer In Michigan, K. L. Cool, James Haveman, Dan Wyant Sep 1997

Recommendations For Elimination Of Bovine Tuberculosis In Free-Ranging White-Tailed Deer In Michigan, K. L. Cool, James Haveman, Dan Wyant

Michigan Bovine Tuberculosis Bibliography and Database

A significant infection rate of bovine TB in the deer population of the northeastern lower peninsula poses a potential risk to several important values including public health, United States Department of Agriculture (U.S.D.A.) TB-free accreditation for Michigan cattle, wildlife health, wildlife-related recreation and tourism and economic stability in several sectors. A risk assessment study by the U.S. D.A. Centers for Epidemiology and Animal Health (Fort Collins, CO) predicted that if no changes were made in the management of the affected free-ranging deer population, the TB prevalence (compared to the current prevalence of 2.3%). Although the current annual risk of TB …


Analysis Of Bovine Herpesvirus 1 Transcripts During A Primary Infection Of Trigeminal Ganglia Of Cattle, Luis M. Schang, Clinton J. Jones Sep 1997

Analysis Of Bovine Herpesvirus 1 Transcripts During A Primary Infection Of Trigeminal Ganglia Of Cattle, Luis M. Schang, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

During an infection of nonneuronal cells, bovine herpesvirus 1 (BHV-1) gene expression proceeds in a well-defined cascade. Products of immediate-early (IE) genes are expressed first, and they activate expression of early (E) and late (L) genes. Although the same cascade is assumed to occur during an infection of neurons in trigeminal ganglia (TG) of cattle, no experimental data is available to support this hypothesis. Consequently, we analyzed BHV-1 gene expression in bovine TG at 1, 2, 4, 7, and 15 days postinfection (dpi). Infectious virus was detected in ocular swabs from 1 to 7 dpi but not 15 dpi. By …

The Place Of Persons With Disabilities In Rotuman Society, Jan Rensel, Alan Howard Sep 1997

The Place Of Persons With Disabilities In Rotuman Society, Jan Rensel, Alan Howard

Pacific Studies

In Rotuma, as in many other small, face-to-face societies, persons with disabilities are treated not as members of categories based on their conditions, but as individuals having whole constellations of characteristics and interpersonal histories. Their roles are not scripted on the basis of disabilities, but patterned by a number of key cultural principles that guide all relationships, including notions of immanent justice for wrongdoing, expectations of generosity and reciprocity, personal autonomy, and concern for family honor. Case studies and analyses of exchange interactions are presented to illustrate these points.

Consumer Debt, Alcohol Use, And Domestic Violence In Guam, Thomas K. Pinhey, Daniel A. Lennon, Nicholas A. Pinhey Sep 1997

Consumer Debt, Alcohol Use, And Domestic Violence In Guam, Thomas K. Pinhey, Daniel A. Lennon, Nicholas A. Pinhey

Pacific Studies

Using community-level economic and crime data derived from secondary sources, this brief study explores the relationships between consumer debt, alcohol use, and domestic violence in Guam for the years 1982 through 1993. The results of the analysis indicate that higher levels of consumer debt are strongly related to greater alcohol consumption and domestic violence, thus suggesting that “financial strain” may be an important variable for understanding patterns of substance abuse and family violence in Guam. The implications of these results for theory and future research on substance abuse and domestic violence are also discussed.

Sqt1, Which Encodes An Essential Wd Domain Protein Of Saccharomyces Cerevisiae, Suppresses Dominant-Negative Mutations Of The Ribosomal Protein Gene Qsr1., Dominic P. Eisinger, Frederick A. Dick, Elke Denke, Bernard L. Trumpower Sep 1997

Sqt1, Which Encodes An Essential Wd Domain Protein Of Saccharomyces Cerevisiae, Suppresses Dominant-Negative Mutations Of The Ribosomal Protein Gene Qsr1., Dominic P. Eisinger, Frederick A. Dick, Elke Denke, Bernard L. Trumpower

Dartmouth Scholarship

QSR1 is an essential Saccharomyces cerevisiae gene, which encodes a 60S ribosomal subunit protein required for joining of 40S and 60S subunits. Truncations of QSR1 predicted to encode C-terminally truncated forms of Qsr1p do not substitute for QSR1 but do act as dominant negative mutations, inhibiting the growth of yeast when expressed from an inducible promoter. The dominant negative mutants exhibit a polysome profile characterized by 'half-mer' polysomes, indicative of a subunit joining defect like that seen in other qsr1 mutants (D. P. Eisinger, F. A. Dick, and B. L. Trumpower, Mol. Cell. Biol. 17:5136-5145, 1997.) By screening a high-copy …


Increased Focal Adhesion Kinase- And Urokinase-Type Plasminogen Activator Receptor-Associated Cell Signaling In Endothelial Cells Exposed To Asbestos, A Barchowsky, B M. Lannon, L C. Elmore, M D. Treadwell Sep 1997

Increased Focal Adhesion Kinase- And Urokinase-Type Plasminogen Activator Receptor-Associated Cell Signaling In Endothelial Cells Exposed To Asbestos, A Barchowsky, B M. Lannon, L C. Elmore, M D. Treadwell

Dartmouth Scholarship

Exposure of low-passage endothelial cells in culture to nonlethal amounts of asbestos, but not refractory ceramic fiber-1, increases cell motility and gene expression. These changes may be initiated by the fibers mimicking matrix proteins as ligands for receptors on the cell surface. In the present study, 1- to 3-hr exposures of endothelial cells to 5 mg/cm2 of chrysotile asbestos caused marked cell elongation and motility. However, little morphological change was seen when chrysotile was added to cells pretreated with either mannosamine to prevent assembly of glycophosphatidylinositol (GPI)-anchored receptors or with herbimycin A to inhibit tyrosine kinase activity. Affinity purification of …

Knowledge Structures: An End To The Redundancy And The Confusion, Doreen Comerford

Link Foundation Modeling, Simulation and Training Fellowship Reports

Situation awareness (SA) is most commonly defined as "the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future" (Endsley, 1995, p. 36). While researching this construct, we were continuously faced with several terms that, like SA, have themselves never been uniformly defined. For example, the following terms have, in some way, been associated with the construct known as SA: device model, domain model, mental model, script, schema, and "the picture" among others (c.f., Mogford, 1994; Endsley, 1995; Garland & Hopkin, …

Intimacy Deficits, Fear Of Intimacy, And Loneliness Among Sexual Offenders, Kurt M. Bumby, David J. Hansen Sep 1997

Intimacy Deficits, Fear Of Intimacy, And Loneliness Among Sexual Offenders, Kurt M. Bumby, David J. Hansen

Department of Psychology: Faculty Publications

Intimacy deficits and loneliness recently have been theorized as influential factors in the etiology and maintenance of sexually offending behaviors, although to date there has been a lack of empirical research conducted to address this proposition. The present study examined intimacy defi cits, fear of intimacy, and loneliness among intrafamilial child molesters, rapists, nonsexually offending inmates, and a community sample of adult males. The child molesters and rapists reported greater overall intimacy deficits than did the nonsexually offending inmates and community controls, with rapists reporting the greatest intimacy deficits. Fear of intimacy was found to be a particularly salient characteristic …

Cell Signaling Pathways Elicited By Asbestos, B T. Mossman, S Faux, Y Janssen, L A. Jimenez, Cynthia Timblin, Christine Zanella, Jonathan Goldberg, Eric Walsh, Aaron Barchowsky, Kevin Driscoll

Dartmouth Scholarship

In recent years, it has become apparent that minerals can trigger alterations in gene expression by initiating signaling events upstream of gene transactivation. These cascades may be initiated at the cell surface after interaction of minerals with the plasma membrane either through receptorlike mechanisms or integrins. Alternatively, signaling pathways may be stimulated by active oxygen species generated both during phagocytosis of minerals and by redox reactions on the mineral surface. At least two signaling cascades linked to activation of transcription factors, i.e., DNA-binding proteins involved in modulating gene expression and DNA replication, are stimulated after exposure of lung cells to …

Qsr1p, A 60s Ribosomal Subunit Protein, Is Required For Joining Of 40s And 60s Subunits., Dominic P. Eisinger, Frederick A. Dick, Bernard L. Trumpower

Dartmouth Scholarship

QSR1 is a recently discovered, essential Saccharomyces cerevisiae gene, which encodes a 60S ribosomal subunit protein. Thirty-one unique temperature-sensitive alleles of QSR1 were generated by regional codon randomization within a conserved 20-amino-acid sequence of the QSR1-encoded protein. The temperature-sensitive mutants arrest as viable, large, unbudded cells 24 to 48 h after a shift to 37 degrees C. Polysome and ribosomal subunit analysis by velocity gradient centrifugation of lysates from temperature-sensitive qsr1 mutants and from cells in which Qsr1p was depleted by down regulation of an inducible promoter revealed the presence of half-mer polysomes and a large pool of free 60S …
