Department of Microbiology and Immunology Faculty Papers

The oncogenic BCR/ABL protein protects hematopoietic cells from apoptosis induced by growth factor deprivation, but the mechanisms are only partially understood. A BCR/ABL mutant lacking amino acids 176-426 in the BCR domain (p185DeltaBCR) failed to protect interleukin 3-deprived 32Dcl3 myeloid precursor cells from apoptosis, although it possessed tyrosine kinase activity and was capable of activating the Ras-Raf-MAP kinase pathway. Compared to p185 wild-type transfectants, p185DeltaBCR-transfected cells showed markedly reduced levels of Bcl-2 and expressed the hypophosphorylated, proapoptotic form of BAD. Bcl-2 expression in the mitochondrial fraction of p185DeltaBCR cells was also markedly diminished and mitochondrial RAF was undetectable. In p185DeltaBCR …

Clinical Interpretation Of "Health And The Human Spirit For Occupation"., Janice P. Burke Jun 1998

Clinical Interpretation Of "Health And The Human Spirit For Occupation"., Janice P. Burke

Department of Occupational Therapy Faculty Papers

In reading and contemplating Yenca's (1998) article, I was immediately struck by the utility of the ideas she offers on a number of clinical fronts. We are presented with occupation-based strategies that are directly applicable to our work with patients and program development; we can make use of the language and ideas that are offered as a way to begin talking to one another (therapist to therapist) in clinical settings about occupation; and we are given the opportunity to think about the contribution, value, and efficacy of occupation and how we might convert those ideas into clinically based research actions. …


Postoperative Nursing Care Contributions To Symptom Distress And Functional Status After Ambulatory Surgery, Beth Ann Swan Jun 1998

Postoperative Nursing Care Contributions To Symptom Distress And Functional Status After Ambulatory Surgery, Beth Ann Swan

College of Nursing Faculty Papers & Presentations

The relationship of postoperative patient-perceived nurse caring behaviors to symptom distress and functional status in 100 adult ambulatory surgical patients was examined. These behaviors explained 9.3% to 18.2% of the variance in functional status on the 1st, 4th, and 7th day postsurgery, and 10% of the variance in symptom distress on the 7th postoperative day after controlling for ASA physical status classification, preoperative symptom distress, and preoperative functional status.

The Baculovirus Anti-Apoptotic P35 Protein Promotes Transformation Of Mouse Embryo Fibroblasts., M Resnicoff, B. Valentinis, D. Herbert, D. Abraham, P D. Friesen, E. S. Alnemri, R Baserga Apr 1998

The Baculovirus Anti-Apoptotic P35 Protein Promotes Transformation Of Mouse Embryo Fibroblasts., M Resnicoff, B. Valentinis, D. Herbert, D. Abraham, P D. Friesen, E. S. Alnemri, R Baserga

Department of Microbiology and Immunology Faculty Papers

The baculovirus p35 protein is a potent inhibitor of programmed cell death induced by a variety of stimuli in insects, nematodes, and mammalian cell lines. The broad ability of p35 in preventing apoptosis has led us to investigate its effect on mouse embryo fibroblasts in vitro and in vivo. For this purpose, we have used R- cells (3T3-like fibroblasts derived from mouse embryos with a targeted disruption of the insulin-like growth factor I receptor (IGF-IR) genes) and R508 cells (derived from R- and with 15 x 10(3) IGF-IRs per cell). Both cell lines grow normally in monolayer, but they do …


Identification Of Fetal Dna And Cells In Skin Lesions From Women With Systemic Sclerosis, Carol M. Artlett, J. Bruce Smith, Sergio A. Jimenez Apr 1998

Identification Of Fetal Dna And Cells In Skin Lesions From Women With Systemic Sclerosis, Carol M. Artlett, J. Bruce Smith, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

BACKGROUND: Systemic sclerosis is a disease of unknown origin which often occurs in women after their childbearing years. It has many clinical and histopathological similarities to chronic graft-versus-host disease. Recent studies indicate that fetal stem cells can survive in the maternal circulation for many years post partum. This finding suggests that fetal cells persisting in the maternal circulation or tissues could be involved in the pathogenesis of systemic sclerosis by initiating a graft-versus-host reaction.

METHODS: We used the polymerase chain reaction (PCR) to identify Y-chromosome sequences in DNA extracted from peripheral-blood cells and skin lesions from women with systemic sclerosis …


How Occupational Therapists Teach Older Patients To Use Bathing And Dressing Devices In Rehabilitation., Ruth Levine Schemm, Laura N. Gitlin Apr 1998

How Occupational Therapists Teach Older Patients To Use Bathing And Dressing Devices In Rehabilitation., Ruth Levine Schemm, Laura N. Gitlin

Department of Occupational Therapy Faculty Papers

OBJECTIVE: This article describes the methods occupational therapists use to teach bathing and dressing device use to older patients in rehabilitation programs. The relationship of three patient characteristics to five aspects of assistive device instruction was examined.

METHOD: The study sample included 86 patients and 19 occupational therapists who provided the assistive device training. Patients were 55 years of age or older and in rehabilitation for an orthopedic deficit, cerebrovascular accident, or lower limb amputation. Therapists recorded information on teaching methods, perceptions of patient knowledge, and expectations for future device use after each treatment session.

RESULTS: Patients received an average …

Mitochondrial Myopathy With Atypical Subacute Presentation, Oren Cohen, Israel Steiner, Zohar Argov, Avi Ashkenazi, Judith Diment, Ann Saada, Yaron River Mar 1998

Mitochondrial Myopathy With Atypical Subacute Presentation, Oren Cohen, Israel Steiner, Zohar Argov, Avi Ashkenazi, Judith Diment, Ann Saada, Yaron River

Department of Neurology Faculty Papers

Mitochondrial myopathies usually have a chronic course of progressive limb weakness, exercise induced myalgia without muscle tenderness, and normal or only mildly raised serum creatine kinase. Acute or subacute presentation or exacerbation of nervous system signs is common in Leber's hereditary optic neuropathy (LHON) and in mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS), but has not been reported for muscle in mitochondrial diseases. We describe a patient who presented with rapidly progressive, subacute muscle weakness due to a mitochondrial disorder.

Student Level Ii Fieldwork Failure: Strategies For Intervention., Sharon A. Gutman, Paula Mccreedy, Prudence Heisler

Department of Occupational Therapy Faculty Papers

OBJECTIVE: This report describes how common student communicative and behavioral characteristics that appear to predict the existence of potential problems during Level II fieldwork were identified in order to develop and implement preventative interventions during the academic curriculum at New York University (NYU). RECORD REVIEW: A record review of NYU professional-level occupational therapy students from 1986 to 1995 was completed to identify common factors among students who performed well academically but failed clinical fieldwork. Eight communicative and behavioral characteristics were identified: (a) rigidity of thinking, (b) discomfort with the ambiguity that accompanies clinical reasoning, (c) lack of psychological insight, (d) …

Initial Multicenter Experience With Double Nucleoside Therapy For Human Immunodeficiency Virus Infection During Pregnancy., N S Silverman, D H Watts, J Hitti, D M Money, E Livingston, J Axelrod, J M Ernest, D Robbins, M M Divito

Department of Obstetrics and Gynecology Faculty Papers

OBJECTIVE: To study maternal and neonatal effects of combination nucleoside analog therapy administered to human immunodeficiency virus (HIV)-infected pregnant women for maternal indications.

METHODS: A multicenter, prospective observational study was undertaken at six perinatal centers in the United States and Canada that supported regional referral programs for the treatment of HIV-infected pregnant women. Demographic, laboratory, and pregnancy outcome data were collected for 39 women whose antiretroviral treatment regimens were expanded to include more than one nucleoside analog for maternal indications. The 40 newborns were monitored at pediatric referral centers through at least three months of age to ascertain their HIV …

Determinants Of Antepartum Human Immunodeficiency Virus Testing In A Non-Medicaid Obstetric Population., E Cardonick, S Daly, M Dooley, K Elles, N S Silverman

Department of Obstetrics and Gynecology Faculty Papers

OBJECTIVE: To determine voluntary human immunodeficiency virus (HIV) testing rates and factors influencing testing in a private obstetric practice.

METHODS: Antepartum patients were offered HIV testing after completing a self-assessment questionnaire. Perceived risks and demographics were correlated with testing rates.

RESULTS: Overall, 348/600 (58%) women consented to HIV testing. In a univariate analysis, patients with "any" perceived risk(s) were more likely to be tested. Single women and those with an at-risk partner(s) or a history of sexually transmitted disease (STD) were more likely to desire testing. These factors remained independently associated with voluntary testing in a multivariate regression model. No …

Anthroposophic Perspectives In Primary Care, Ira S. Cantor Md, Steven Rosenzweig Md Dec 1997

Anthroposophic Perspectives In Primary Care, Ira S. Cantor Md, Steven Rosenzweig Md

Department of Emergency Medicine Faculty Papers

A core challenge of contemporary medicine is to integrate the technological successes of biomedical science with a comprehensive under-standing of the physical, psychosocial, ecological, and spiritual dimensions of health and illness. Toward this end, bridges are being created between conventional medicine and alternative systems of healing which reflect a holistic model of the human being. Even when both conventional and complementary approaches are used side-by-side in the same patient, they remain separate in their basic assumptions and goals. Today's mechanistic disease model is cut off from such notions as life-energy, consciousness, and spirituality, so integral to many alternative paradigms. Anthroposophically …


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 Nov 1997

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 …


Occupational Therapy's Link To Vocational Reeducation, 1910-1925., Sharon A. Gutman Nov 1997

Occupational Therapy's Link To Vocational Reeducation, 1910-1925., Sharon A. Gutman

Department of Occupational Therapy Faculty Papers

The development of occupational therapy is rooted in early 20th century medical reform. During the early 1910s, several members of the medical profession, human service workers, and the larger American society were increasingly disturbed by medical practices that did not consider the individual's personal experience of disability. Occupational therapy was developed, in part, out of this desire to provide persons with treatment that helped them to function in their communities despite their disability. Early occupational therapy leaders envisioned the fledgling profession as a societal service capable of assisting persons with disabilities to return to both work and community life. Vocational …


Predicting Red Blood Cell Transfusions In Very Low Birth Weight Infants Based On Clinical Risk Factors., David A. Paul, Stephen A. Pearlman, Kathleen H. Leef, John L. Stefano Nov 1997

Predicting Red Blood Cell Transfusions In Very Low Birth Weight Infants Based On Clinical Risk Factors., David A. Paul, Stephen A. Pearlman, Kathleen H. Leef, John L. Stefano

Department of Pediatrics Faculty Papers

OBJECTIVE: To describe the clinical factors most predictive of red blood cell transfusion in very low birth weight (VLBW) infants.

STUDY DESIGN: Retrospective review of VLBW infants cared for at a single level III NICU during a two year period, n = 199.

RESULTS: Overall transfusion requirement was 4.6 +/- 6.2 transfusions/infant/hospital course. Length of hospital stay, days of mechanical ventilation, requirement for dopamine support, birth weight, initial hematocrit, periventricular leukomalacia and necrotizing enterocolitis all independently correlated with number of transfusions and donors. Bronchopulmonary dysplasia and patent ductus arteriosus were associated with donor but not transfusion number.

CONCLUSIONS: Our data …


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 Oct 1997

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 …

Department of Medicine Faculty Papers

BACKGROUND: Treatment of stenosis in saphenous-vein grafts after coronary-artery bypass surgery is a difficult challenge. The purpose of this study was to compare the effects of stent placement with those of balloon angioplasty on clinical and angiographic outcomes in patients with obstructive disease of saphenous-vein grafts.

METHODS: A total of 220 patients with new lesions in aortocoronary-venous bypass grafts were randomly assigned to placement of Palmaz-Schatz stents or standard balloon angioplasty. Coronary angiography was performed during the index procedure and six months later.

RESULTS: As compared with the patients assigned to angioplasty, those assigned to stenting had a higher rate …

Mirizzi Syndrome Type Ii: Is Laparoscopic Cholecystectomy Justified?, D C Desai, R D Smink

Department of Surgery Faculty Papers

Mirizzi syndrome type II is an uncommon cause of obstructive jaundice caused by an inflammatory response to an impacted gallstone in Hartmann's pouch or the cystic duct with a resultant cholecystocholedochal fistula. Two cases of Mirizzi syndrome type II are presented. Clinically only one patient had jaundice and endoscopic retrograde cholangiopancreatogram (ERCP) established a preoperative diagnosis of Mirizzi syndrome. The other patient's diagnosis of Mirizzi syndrome was made intraoperatively. It is important to properly identify the anatomy at the time of surgery to avoid compromising the common bile duct. Operative treatment of Mirizzi syndrome type II includes laparoscopic or open …

Chronicity In Strongyloides Stercoralis Infections: Dichotomy Of The Protective Immune Response To Infective And Autoinfective Larvae In A Mouse Model., R. A. Brigandi, H. L. Rotman, T. J. Nolan, G. A. Schad, D. Abraham Jun 1997

Chronicity In Strongyloides Stercoralis Infections: Dichotomy Of The Protective Immune Response To Infective And Autoinfective Larvae In A Mouse Model., R. A. Brigandi, H. L. Rotman, T. J. Nolan, G. A. Schad, D. Abraham

Department of Microbiology and Immunology Faculty Papers

Strongyloidiasis is an intestinal disease that can last for decades due to the occurrence of autoinfective larvae (L3a) in an infected person, which contribute to the maintenance of the population of adult worms in the intestine. The goal of the present study was to determine if L3a are susceptible to the protective immunity that targets the infective stage of the worm, the third-stage larvae (L3). Mice immunized and challenged with Strongyloides stercoralis L3 kill more than 90% of challenge larvae contained within diffusion chambers. The L3 do not remain antigenically static in mice, however, but undergo some degree of antigenic …
