A Polymorphism Of A Platelet Glycoprotein Receptor As An Inherited Risk Factor For Coronary Thrombosis., Ethan J. Weiss, Paul F. Bray, Matthew Tayback, Steven P. Schulman, Thomas S. Kickler, Lewis C. Becker, James L. Weiss, Gary Gerstenblith, Pascal J. Goldschmidt-Clermont

Cardeza Foundation for Hematologic Research

BACKGROUND: Platelet glycoprotein IIb/IIIa is a membrane receptor for fibrinogen and von Willebrand factor, and it has an important role in platelet aggregation. It is known to be involved in the pathogenesis of acute coronary syndromes. Previously, we found a high frequency of a particular polymorphism, PlA2, of the gene encoding glycoprotein IIIa in kindreds with a high prevalence of premature myocardial infarction.

METHODS: To investigate the relation between the PlA2 polymorphism and acute coronary syndromes, we conducted a case-control study of 71 case patients with myocardial infarction or unstable angina and 68 inpatient controls without known heart disease. The …

Disruption Of The Cbfa2 Gene Causes Necrosis And Hemorrhaging In The Central Nervous System And Blocks Definitive Hematopoiesis., Qing Wang, Terryl Stacy, Michael M Binder, Miguel Marin-Padilla, Arlene H. Sharpe, Nancy A. Speck

Dartmouth Scholarship

The CBFA2 (AML1) gene encodes a DNA-binding subunit of the heterodimeric core-binding factor. The CBFA2 gene is disrupted by the (8;21), (3;21), and (12;21) chromosomal translocations associated with leukemias and myelodysplasias in humans. Mice lacking a CBF alpha 2 protein capable of binding DNA die between embryonic days 11.5 and 12.5 due to hemorrhaging in the central nervous system (CNS), at the nerve/CNS interfaces of cranial and spinal nerves, and in somitic/intersomitic regions along the presumptive spinal cord. Hemorrhaging is preceded by symmetric, bilateral necrosis in these regions. Definitive erythropoiesis and myelopoiesis do not occur in Cbfa2-deficient embryos, and disruption …

Cd40-Cd40 Ligand Interactions In Experimental Allergic Encephalomyelitis And Multiple Sclerosis., Koen Gerritse, Jon D. Laman, Randolph J. Noelle, Alejandro Aruffo

Dartmouth Scholarship

We investigated the role of CD40-CD40 ligand (CD40L) interactions in multiple sclerosis (MS) and experimental allergic encephalomyelitis (EAE). Activated helper T cells expressing CD40L (gp39) surface protein were found in MS patient brain sections, but not in brain tissue sections of normal controls or patients with other neurological disease. CD40L-positive cells were co-localized with CD40-bearing cells in active lesions (perivascular infiltrates). Most of these CD40-bearing cells proved to be of the monocytic lineage (macrophages or microglial cells), and relatively few were B cells. To functionally evaluate CD40-CD40L interactions, EAE was elicited in mice by means of proteolipid-peptide immunization. Treatment with …

Biochemical And Mutational Analysis Of The Histidine Residues Of Staphylococcal Enterotoxin A., M Hoffman, M Tremaine, J Mansfield, M Betley

Manuscripts, Articles, Book Chapters and Other Papers

The goal of this study was to examine the role of histidine residues in the biological activities of staphylococcal enterotoxin A (SEA). Carboxymethylated SEA was unable to stimulate murine T-cell proliferation but was resistant to monkey stomach lavage fluid degradation, suggesting that native conformation was intact. Site-directed mutagenesis of the histidine residues of SEA was subsequently performed. SEA-H44A (SEA with histidine 44 replaced with alanine), SEA-H44D, SEA-H50A, SEA-H50D, SEA-H114A, SEA-H114D, SEA-H187A, and SEA-H187D retained superantigen and emetic activities, whereas SEA-H225A and SEA-H225D were defective in the ability to stimulate T-cell proliferation. These mutants were unable to compete with SEA for …

Analysis Of The Effects Of Overexpression Of Metallothionein-I In Transgenic Mice On The Reproductive Toxicology Of Cadmium., T Dalton, Kai Fu, G C Enders, R D Palmiter, G K Andrews

Journal Articles: Pathology and Microbiology

Exposure to low levels of cadmium reduces fertility. In male mice spermatogenesis is highly sensitive to cadmium, whereas in females the peri-implantation period of pregnancy is sensitive. To examine the potential roles of the cadmium-binding protein, metallothionein (MT), in the reproductive toxicology of cadmium, we examined a transgenic mouse strain that overexpresses metallothionein-I (MT-I). These mice had dramatically increased steady-state levels of MT-I mRNA and MT in the testes and in the female reproductive tract during the peri-implantation period of pregnancy, and this overexpression occurred in a cell-specific and temporally regulated manner similar to that of the endogenous MT-I gene. …

Ventricular Remodeling Following Infant-Pediatric Cardiac Transplantation. Does Age At Transplantation Or Size Disparity Matter?, Girish S. Shirali, F Lombano, W L. Beeson, D A. Dyar, N F. Mulla, A Khan, J K. Johnston, R E. Chinnock, S R. Gundry, A J. Razzouk

Manuscripts, Articles, Book Chapters and Other Papers

Early left ventricular (LV) remodeling following pediatric cardiac transplantation has not been described. To identify patterns and determinants of change in left ventricular mass and volume posttransplant, we studied 125 consecutive children who underwent cardiac transplantation between January 1, 1989 and July 31, 1993. Two-dimensional imaging-directed M-mode echocardiograms were studied weekly until 26 weeks post-transplant. LV mass and volume (indexed to BSA1.5) were measured. LV mass index increased until 3 weeks post-transplant, and then decreased. The mean decrement in LV mass index after 8 weeks post-transplant (relative to baseline) was significantly larger in patients with donor-recipient weight ratio > 1.5 compared …

A Requirement For Bone Morphogenetic Protein-7 During Development Of The Mammalian Kidney And Eye., Andrew T. Dudley, K. M. Lyons, E. J. Robertson

Journal Articles: Genetics, Cell Biology & Anatomy

BMP-7/OP-1, a member of the transforming growth factor-beta (TGF-beta) family of secreted growth factors, is expressed during mouse embryogenesis in a pattern suggesting potential roles in a variety of inductive tissue interactions. The present study demonstrates that mice lacking BMP-7 display severe defects confined to the developing kidney and eye. Surprisingly, the early inductive tissue interactions responsible for establishing both organs appear largely unaffected. However, the absence of BMP-7 disrupts the subsequent cellular interactions required for their continued growth and development. Consequently, homozygous mutant animals exhibit renal dysplasia and anophthalmia at birth. Overall, these findings identify BMP-7 as an essential …

The First Cut Is (Not) The Deepest: Deconstructing "Female Genital Mutilation" And The Criminalization Of The Other, David Fraser

Dalhousie Law Journal

Deconstruction, as a 'philosophy'andas a strategy for the reading of texts, offers us the ability to engage in a politics and ethics of justice which seeks to recognize our responsibility to the Other. By 'reading' 'female genital mutilation' with this obligation in mind, this article attempts to deal with the prejudices and barriers to justice which present themselves to those of us in the West who seek an engagement with the Other. The article offers a warning and a reading of the 'text' of 'female genital mutilation' informed by our obligation to justice.

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 …

Impact Of Spinal Cord Injury On The Life Roles Of Women., M Claire Quigley

Department of Occupational Therapy Faculty Papers

This qualitative study was conducted to explore and describe the role experience of five women whose lives were disrupted by a traumatic spinal cord injury and who later returned to their communities after completing intensive rehabilitation programs. In-depth interviews and participant observations were used to examine the experiences of these women. The findings exemplify how the women's use of adaptation and negotiation and the development of a new role as self-advocate facilitated the reestablishment of their life roles. As the women's occupational roles were redefined, the processes of adaptation and negotiation were evident in three aspects of their lives: daily …

The Costs Of Eating: A Behavioral Economic Analysis Of Food Refusal., Mary Louise Kerwin, W H Ahearn, P S Eicher, D M Burd

College of Science & Mathematics Departmental Research

Behavioral economic concepts were applied to the analysis and treatment of pediatric feeding disorders in a clinical setting. In Experiment 1, children who chronically refused food were presented with varying amounts of food on a spoon (empty, dipped, quarter, half, and level). Each child exhibited a different but orderly demand function of response (acceptance, expulsion, and mouth clean) by cost (increasing spoon volume) for a constant pay-off of toys and social interaction. In Experiment 2, physical guidance or nonremoval of the spoon for food refusal was initiated at the smallest spoon volume with low levels of acceptance, and was subsequently …

Mentorship Experiences In A Group Of Occupational Therapy Leaders., Ruth Levine Schemm, Theodore Bross

Department of Occupational Therapy Faculty Papers

OBJECTIVES: The development of occupational therapy leaders is a long-held goal of many members of the American Occupational Therapy Association and of state associations. The initiation of mentor programs is a common means to accomplish this goal. These programs take time and effort, and, although occupational therapists have described how mentorship programs work in the literature, there are few articles that describe the actual mentorship experiences of occupational therapy leaders.

METHOD: To study the experiences of elected occupational therapy leaders, a 30-item questionnaire was distributed at the annual meeting of the Committee of State Association Presidents and completed by 53 …

Roc Curve Regression Analysis: The Use Of Ordinal Regression Models For Diagnostic Test Assessment, Anna N.A. Tosteson, Milton C. Weinstein, Jack Wittenberg, Colin B. Begg

Dartmouth Scholarship

Diagnostic tests commonly are characterized by their true positive (sensitivity) and true negative (specificity) classification rates, which rely on a single decision threshold to classify a test result as positive. A more complete description of test accuracy is given by the receiver operating characteristic (ROC) curve, a graph of the false positive and true positive rates obtained as the decision threshold is varied. A generalized regression methodology, which uses a class of ordinal regression models to estimate smoothed ROC curves has been described. Data from a multi-institutional study comparing the accuracy of magnetic resonance (MR) imaging with computed tomography (CT) …

Teirstein, R. David Fish, Antonio Colombo, Jeffrey Brinker, Jeffrey Moses, Alex Shaknovich, John Hirshfeld, Stephen Bailey, Stephen Ellis, Randal Rake, Sheldon Goldberg

Department of Medicine Faculty Papers

BACKGROUND: Coronary-stent placement is a new technique in which a balloon-expandable, stainless-steel, slotted tube is implanted at the site of a coronary stenosis. The purpose of this study was to compare the effects of stent placement and standard balloon angioplasty on angiographically detected restenosis and clinical outcomes.

METHODS: We randomly assigned 410 patients with symptomatic coronary disease to elective placement of a Palmaz-Schatz stent or to standard balloon angioplasty. Coronary angiography was performed at base line, immediately after the procedure, and six months later.

RESULTS: The patients who underwent stenting had a higher rate of procedural success than those who …

Preimplantation Development Of In Vitro-Matured And In Vitro-Fertilized Ovine Zygotes: Comparison Between Coculture On Oviduct Epithelial Cell Monolayers And Culture Under Low Oxygen Atmosphere., A J Watson, P H Watson, D Warnes, S K Walker, D T Armstrong, R F Seamark

Obstetrics & Gynaecology Publications

The roles of medium composition, serum source, embryo coculture, and culture under low O2 conditions on the development of in vitro-matured and in vitro-fertilized (IVMF) ovine zygotes were investigated in three separate experiments. In the first experiment, the proportion of cocultured IVMF zygotes developing to the blastocyst stage was significantly higher (38.0% vs. 3.5%; p < 0.05) than that of non-cocultured zygotes treated within three embryo culture media (TCM-199 + 10% fetal bovine serum [FBS]; bicarbonate-buffered, glucose-free synthetic oviduct fluid medium [mod-SOFM] + 10% FBS; and bicarbonate-buffered BSA-free Tyrode's salt solution [mod-TALP] + 10% FBS) under a 5% CO2 atmosphere in air. In a second experiment, a significantly higher (p < 0.05) proportion of cocultured zygotes placed in TCM-199 medium survived to the blastocyst stage (37.4% blastocysts vs. 23.4% in mod-SOFM). No significant effect of serum (FBS vs. human serum [HS]) was observed on embryonic development, but coculture was confirmed to exert a significant influence on development to the blastocyst stage. In the final experiment, survival of the embryo under a reduced oxygen (5% CO2:5% O2:90% N2) atmosphere was investigated. In contrast to results in the initial experiments, embryonic survival was significantly higher (p < 0.05) in the non-cocultured treatment groups (21.9% blastocysts vs. 0.4% for cocultured zygotes). Serum source also had a significant (p < 0.05) influence upon the development of non-cocultured zygotes: 32.3% of zygotes cultured with HS progressed to the blastocyst stage vs. 11.5% of zygotes cultured in FBS-supplemented medium. These results have characterized two distinct culture environments, each capable of supporting the development of high frequencies of unselected IVMF zygotes to the blastocyst stage in vitro.

A Growth Factor Phenotype Map For Ovine Preimplantation Development., A J Watson, P H Watson, M Arcellana-Panlilio, D Warnes, S K Walker, G A Schultz, D T Armstrong, R F Seamark

Obstetrics & Gynaecology Publications

The reverse transcription-polymerase chain reaction (RT-PCR) was used to determine the patterns of expression for several growth factor ligand and receptor genes during ovine preimplantation development. Transcripts for insulin-like growth factor (IGF)-I, IGF-II, and the receptors for insulin and IGF-I were detected throughout ovine preimplantation development from the 1-cell to the blastocyst stage. Transforming growth factor alpha (TGF alpha) transcripts were also detected throughout ovine preimplantation development. The mRNAs encoding basic fibroblast growth factor (bFGF) were detected in all stages of the ovine preimplantation embryo, although the relative abundance of this transcript consistently decreased from the 1-cell to the blastocyst …

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 …

Possible Roles Of Insulin And Insulin-Like Growth Factors In Rat Preimplantation Development: Investigation Of Gene Expression By Reverse Transcription-Polymerase Chain Reaction., X Zhang, G M Kidder, A J Watson, G A Schultz, D T Armstrong

Obstetrics & Gynaecology Publications

The sensitive mRNA phenotyping technique of reverse transcription-polymerase chain reaction was used to demonstrate that insulin receptor mRNA is present in rat embryos during the preimplantation period. In addition, mRNA encoding insulin-like growth factor (IGF) type I and type II receptors have also been detected in rat preimplantation embryos. IGF-I mRNA was not detected in preimplantation embryos but was found in oviducts and uteri of prepubertal and early pregnant rats. IGF-II mRNA was present in both embryos and in oviducts and uteri during the preimplantation period. These findings suggest that insulin and IGF-I could influence early embryo development in endocrine …

Management Decisions Made By Caregiver Spouses Of Persons With Alzheimer's Disease., Mary A. Corcoran

Department of Occupational Therapy Faculty Papers

OBJECTIVES: As the incidence of Alzheimer's disease increases, so does the effect on families and friends who assume caregiving responsibilities. Despite the proliferation of caregiving studies reported in the literature, little is known of the day-to-day management styles and preferences of caregivers. To develop, implement, and test interventions designed to sustain caregivers in their role, more information is needed about the caregiving experience. Results of a descriptive study are presented as a first step in understanding the complex process of choosing, organizing, and implementing everyday caregiving tasks.

METHOD: Subjects of the study were 26 persons who provide care for a …

Ochrobactrum Anthropi Bacteremia In A Child., Joel D. Klein, Stephen C. Eppes

Department of Pediatrics Faculty Papers

Children undergoing chemotherapy for cancer are at increased risk of supervening infection, including bacteremia. This may be due to immunosuppression as well as the presence of intravascular devices such as central venous catheters. Bacteria responsible for these infections include those found in the child's endogenous flora as well as in environmental sources. We report the case of a child with acute lymphoblastic leukemia (ALL) who developed bacteremia secondary to Ochrobactrum anthropi. Details of this extremely rare infection are the focus of this report.

Sequencing Of Cdna From 50 Unrelated Patients Reveals That Mutations In The Triple-Helical Domain Of Type Iii Procollagen Are An Infrequent Cause Of Aortic Aneurysms., Gerard Tromp, Yuli Wu, Darwin J.

Department of Biochemistry and Molecular Biology Faculty Papers

Detailed DNA sequencing of the triple-helical domain of type III procollagen was carried out on cDNA prepared from 54 patients with aortic aneurysms. The 43 male and 11 female patients originated from 50 different families and five different nationalities. 43 patients had at least one additional blood relative who had aneurysms. Five overlapping asymmetric PCR products, covering all the coding sequences of the triple-helical domain of type III procollagen, were sequenced with 28 specific sequencing primers. Analysis of the sequencing gels revealed only two nucleotide changes that altered the structure of the protein. One was a substitution of threonine for …

Regulation Of Human Lung Fibroblast Alpha 1(I) Procollagen Gene Expression By Tumor Necrosis Factor Alpha, Interleukin-1 Beta, And Prostaglandin E2., Arturo Diaz, Elena Munoz, Rosemary Johnston, Joseph H. Korn, Sergio A. Jimenez

Department of Medicine Faculty Papers

We investigated the participation of prostaglandin (PG) E2 in the regulation of the alpha 1(I) procollagen gene expression by tumor necrosis factor alpha (TNF alpha), and interleukin-1 beta (IL-1 beta) in normal adult human lung fibroblasts. TNF alpha (100 units/ml) and IL-1 beta (100 units/ml) stimulated the production of PGE2 and caused a dose-dependent inhibition of up to 54 and 66%, respectively, of the production of type I procollagen. Preincubation of cultures with indomethacin partially reversed the inhibition of procollagen production induced by the cytokines. Cytokine-stimulated endogenous fibroblast PG accounted for 35 and 68% of the inhibition induced by TNF …
