Can An Anesthesia Machine Flush Valve Provide For Effective Jet Ventilation?, S D Gaughan, J L Benumof, G T Ozaki Apr 1993

Can An Anesthesia Machine Flush Valve Provide For Effective Jet Ventilation?, S D Gaughan, J L Benumof, G T Ozaki

Faculty, Staff and Student Publications

Transtracheal jet ventilation (TTJV) using a percutaneously inserted intravenous (IV) catheter for the patient who cannot be ventilated or tracheally intubated or, using a jet stylet for changing endotracheal tubes (ETT) in patients for whom subsequent ventilation and/or tracheal reintubation may be difficult, are extremely valuable therapeutic options. The jet ventilation system must have a sufficiently high pressure-oxygen source to drive oxygen through noncompliant tubing and through relatively small IV catheters and/or jet stylets in order to achieve adequate ventilation and oxygenation. There is no evidence that using the common gas outlet of an anesthesia machine by activating the flush …

A Model To Promote Activity Competence In Elders., Ruth E. Levine, Laura N. Gitlin Feb 1993

A Model To Promote Activity Competence In Elders., Ruth E. Levine, Laura N. Gitlin

Department of Occupational Therapy Faculty Papers

This paper describes an occupational therapy home-based intervention in which purposeful activities were used to promote adaptation and competence in older adults with chronic disabilities. Seven home care therapists visited 17 randomly selected, community-living elders who were chronically disabled and who volunteered to participate in the program. The number of visits ranged from 3 to 10 and occurred over a 3-month period according to clients' needs and wishes. Therapists enhanced their ability to enter the client's social and cultural system by using participant-observation techniques and collaboratively identified activities. Therapists documented each home visit with a structured fieldnote form. An analysis …

Plasma Total Glutathione In Humans And Its Association With Demographic And Health-Related Factors, Elaine W. Flagg, Ralph J. Coates, J. William Eley, Raymond S. Greenberg, Dean P. P. Jones, Elaine W. Gunter, Bethany Jackson

Faculty Publications

The tripeptide glutathione is proposed to be protective against a number of chronic diseases including cardiovascular disease and cancer. However, there have been few studies of plasma glutathione levels in humans and in those studies the numbers of participants have been very small. In an exploratory analysis the determinants of plasma total glutathione (GSHt) were investigated in a group of 100 volunteers aged 18–61 years in Atlanta, Georgia, USA during June and July 1989. Data on demographic and health-related factors were collected by interview and plasma GSHt was measured using a recently modified laboratory method. The mean concentration of plasma …

Gender Differences In Dementia Management Plans Of Spousal Caregivers: Implications For Occupational Therapy., Mary A. Corcoran Nov 1992

Gender Differences In Dementia Management Plans Of Spousal Caregivers: Implications For Occupational Therapy., Mary A. Corcoran

Department of Occupational Therapy Faculty Papers

Occupational therapists treating older people with Alzheimer disease know that they must also consider the others who are affected by the disease, the informal caregivers. Intervention is most effective when it enables both the impaired person and the primary caregiver to manage the secondary symptoms of dementia. Unfortunately, little is understood about how caregivers approach and carry out their tasks and about why male and female caregivers respond differently to their caregiving role in terms of depression, burden, stress, and substance abuse. This paper discusses the effects of gender on dementia management plans of spousal caregivers. Husbands and wives have …

Indistinguishable Nuclear Factor Binding To Functional Core Sites Of The T-Cell Receptor Delta And Murine Leukemia Virus Enhancers., Juan M. Redondo, Jeffrey L. Pfohl, Cristina Hernandez-Munain, Shuwen Wang, Nancy A. Speck, Michael S. Krangel Nov 1992

Indistinguishable Nuclear Factor Binding To Functional Core Sites Of The T-Cell Receptor Delta And Murine Leukemia Virus Enhancers., Juan M. Redondo, Jeffrey L. Pfohl, Cristina Hernandez-Munain, Shuwen Wang, Nancy A. Speck, Michael S. Krangel

Dartmouth Scholarship

We have previously shown that the delta E3 site is an essential element for transcriptional activation by the human T-cell receptor (TCR) delta enhancer and identified two factors, NF-delta E3A and NF-delta E3C, that bound to overlapping core (TGTGGTTT) and E-box motifs within delta E3. In this study, we show that protein binding to the core motif is necessary but not sufficient for transcriptional activation by the delta E3 element. In contrast, protein binding to the E-box motif does not contribute significantly to enhancer activity. A similar core motif present within the enhancers of T-cell-tropic murine retroviruses has been shown …

How To Make A Blastocyst., A J Watson, G M Kidder, G A Schultz

Obstetrics & Gynaecology Publications

Several of the new reproductive technologies have been cultivated from our current understanding of the genetic programming and cellular processes that are involved in the major morphogenetic events of mammalian preimplantation development. Research directed at characterizing the patterns of gene expression during early development has shown that the embryo is initially under maternal control and later superseded by new transcriptional activity provided by the activation of the embryonic genome. Several embryonic transcripts encoding: (i) growth factors, (ii) cell junctions, (iii) plasma membrane ion transporters, and (iv) cell adhesion molecules have been identified as contributing directly to the progression of the …

Modulation Of Cisplatin Sensitivity And Growth Rate Of An Ovarian Carcinoma Cell Line By Bombesin And Tumor Necrosis Factor-Alpha., Seiji Isonishi, Antti P. Jekunen, Doreen K. Hom, Alan Eastman, Peter S. Edelstein, Franz B. Thiebaut, Randolph D. Christen, Stephen B. Howell Oct 1992

Modulation Of Cisplatin Sensitivity And Growth Rate Of An Ovarian Carcinoma Cell Line By Bombesin And Tumor Necrosis Factor-Alpha., Seiji Isonishi, Antti P. Jekunen, Doreen K. Hom, Alan Eastman, Peter S. Edelstein, Franz B. Thiebaut, Randolph D. Christen, Stephen B. Howell

Dartmouth Scholarship

A twofold change in the cisplatin (DDP) sensitivity of 2008 human ovarian carcinoma cells is sufficient to reduce tumor response in vivo. The DDP sensitivity of these cells can be enhanced by activation of the epidermal growth factor and protein kinase C signal transduction pathways. We report here that two endogenous growth factors, bombesin and tumor necrosis factor alpha (TNF alpha), enhanced DDP sensitivity by factors of 1.7 +/- 0.1 (SD)-fold and 1.8 +/- 0.1 (SD)-fold, respectively. Both agents also produced sensitization in an 11-fold DDP-resistant 2008 subline. Neither bombesin nor TNF alpha changed the accumulation of DDP, glutathione content, …

A Phorbol Ester Response Element Within The Human T-Cell Receptor Beta-Chain Enhancer., Haydn M. Prosser, David Wotton, Anne Gegonne, Jacques Ghysdael, Shuwen Wang, Nancy A. Speck, Michael J. Owen Oct 1992

A Phorbol Ester Response Element Within The Human T-Cell Receptor Beta-Chain Enhancer., Haydn M. Prosser, David Wotton, Anne Gegonne, Jacques Ghysdael, Shuwen Wang, Nancy A. Speck, Michael J. Owen

Dartmouth Scholarship

The activity of the T-cell receptor beta-chain gene enhancer is increased by activators of the protein kinase C pathway during T-cell activation. Analysis of mutant enhancer constructs identified two elements, beta E2 and beta E3, conferring phorbol ester inducibility. Multimerized beta E2 acted in isolation as a phorbol ester-responsive element. Both beta E2 and beta E3, which contain a consensus Ets-binding site, were shown to bind directly to the product of the c-ets-1 protooncogene. Both regions also bound a second factor, core-binding factor. Mutation of the beta E2 Ets site abolished the inducibility of the beta E2 multimer. beta E2 …

Dementia Management: An Occupational Therapy Home-Based Intervention For Caregivers., Mary A. Corcoran, Laura N. Gitlin Sep 1992

Dementia Management: An Occupational Therapy Home-Based Intervention For Caregivers., Mary A. Corcoran, Laura N. Gitlin

Department of Occupational Therapy Faculty Papers

This paper describes an occupational therapy intervention designed for family caregivers of persons with dementia. The intervention, based on the framework of a competence-environmental press model and the principle of collaboration, was implemented during 5 home visits. Each visit was designed to build caregiving skills through collaboration in identifying problem areas, developing and implementing environmental strategies, and modifying management approaches. A case vignette illustrates the therapeutic process and outcomes. The theoretical rationale and structure of the intervention and innovative documentation for evaluation of the theoretic process are also presented.

Antibodies Against Epstein-Barr Nuclear Antigen (Ebna) In Multiple Sclerosis Csf, And Two Pentapeptide Sequence Identities Between Ebna And Myelin Basic Protein., Patrick F. Bray, J Luka, Paul F. Bray, K W. Culp, J P. Schlight

Cardeza Foundation for Hematologic Research

The Epstein-Barr virus (EBV) causes infectious mononucleosis and is linked to several disparate malignancies. Prior studies on patients with multiple sclerosis (MS) showed that 100% are EBV-seropositive and that their blood contains higher antibody titers than those of controls to both transformation and lytic cycle antigens. We performed three different assays for antibodies in CSF to three major EBV antigens from patients with MS and controls. Among 93 patients with MS, 79 (85%) had CSF that reacted with a 70 kD protein, shown to be the nuclear antigen, EBNA-1, whereas only 11 (13%) of 81 EBV-seropositive controls reacted, p less …

Alternative Splicing Of Human Prostaglandin G/H Synthase Mrna And Evidence Of Differential Regulation Of The Resulting Transcripts By Transforming Growth Factor Beta 1, Interleukin 1 Beta, And Tumor Necrosis Factor Alpha., Arturo Diaz, Anthony M. Reginato, Sergio A. Jimenez

Department of Medicine Faculty Papers

Prostaglandin G/H synthase (PGG/HS) is the rate-limiting enzyme in the conversion of arachidonic acid to prostaglandins and thromboxanes. We screened a human lung fibroblast cDNA library with an ovine PGG/HS cDNA and isolated a 2.3-kilobase clone (HCO-T9). Sequence analysis of this clone showed that (a) it contained the entire translated region of PGG/HS and (b) it displayed an in-frame splicing of the last 111 base pairs encoded by exon 9, which resulted in the elimination of the N-glycosylation site at residue 409. Polymerase chain reaction amplification with specific oligonucleotides of reverse-transcribed mRNA from diverse human tissues and cultured cells yielded …

Regulation Of Transforming Growth Factor-Beta 1 Gene Expression By Glucocorticoids In Normal Human T Lymphocytes., O. Ayanlarbatuman, A. P. Ferrero, Arturo Diaz, Sergio A. Jimenez Nov 1991

Regulation Of Transforming Growth Factor-Beta 1 Gene Expression By Glucocorticoids In Normal Human T Lymphocytes., O. Ayanlarbatuman, A. P. Ferrero, Arturo Diaz, Sergio A. Jimenez

Department of Medicine Faculty Papers

Glucocorticoids (GC) modulate immune function in a number of ways, including suppression of T cell proliferation and other IL-2-mediated T cell functions. These inhibitory effects are similar to those induced by transforming growth factor-beta 1 (TGF-beta 1), a cytokine with potent T cell inhibiting activities. We examined the hypothesis that GC effects may be at least partially achieved through modulation of the expression of the TGF-beta 1 gene in activated T cells. Normal T cells were cultured with or without purified phytohemagglutinin (PHA-p) and 4 beta-phorbol 12-myristate 13-acetate (PMA) in the presence or absence of the synthetic GC, dexamethasone (100-200 …

An Emerging View Of Mastery, Excellence, And Leadership In Occupational Therapy Practice., Janice P Burke, Elizabeth Depoy Nov 1991

An Emerging View Of Mastery, Excellence, And Leadership In Occupational Therapy Practice., Janice P Burke, Elizabeth Depoy

Department of Occupational Therapy Faculty Papers

The recent focus on clinical reasoning in occupational therapy, specifically on how therapists solve complex problems, has stimulated interest in how master clinicians think in practice. By gaining insight into how clinicians think and what they think about when they identify and solve problems, we may be able to identify clinical reasoning patterns and processes that occupational therapy students and novice therapists need to experience in order to progress in their practice or to emerge as leaders in their field. Observation of the way in which clinical masters and leaders view challenges and solve problems as manifested in their clinical …

Expression Of A Human Cartilage Procollagen Gene (Col2a1) In Mouse 3t3 Cells., Leena Ala-Kokko, James Hyland, Carol Smith, Kari I. Kivirikko, Sergio A. Jimenez, Darwin J. Prockop Aug 1991

Expression Of A Human Cartilage Procollagen Gene (Col2a1) In Mouse 3t3 Cells., Leena Ala-Kokko, James Hyland, Carol Smith, Kari I. Kivirikko, Sergio A. Jimenez, Darwin J. Prockop

Department of Medicine Faculty Papers

Expression in a recombinant system has been difficult to obtain for any of the major fibrillar collagens that require processing by eight or more post-translational enzymes. Here, two DNA constructs were designed so that the promoter region of the gene for the pro-alpha 1(I) chain of human type I procollagen drove expression of the human type II procollagen gene in mouse NIH 3T3 cells, a culture line that normally synthesizes type I procollagen but not any cartilage-specific protein such as type II procollagen. Both constructs were expressed as both mRNA and protein. In clones expressing the construct at high levels, …

Interleukin-2-Triggered Raf-1 Expression, Phosphorylation, And Associated Kinase Activity Increase Through G1 And S In Cd3-Stimulated Primary Human T Cells., Antanina Zmuidzinas, Harvey J. Mamon, Thomas M. Roberts, Kendall A. Smith May 1991

Interleukin-2-Triggered Raf-1 Expression, Phosphorylation, And Associated Kinase Activity Increase Through G1 And S In Cd3-Stimulated Primary Human T Cells., Antanina Zmuidzinas, Harvey J. Mamon, Thomas M. Roberts, Kendall A. Smith

Dartmouth Scholarship

To gain further insight into the role of Raf-1 in normal cell growth, c-raf-1 mRNA expression, Raf-1 protein production, and Raf-1-associated kinase activity in normal human T cells were analyzed. In contrast to the constitutive expression of Raf-1 in continuously proliferating cell lines, c-raf-1 mRNA and Raf-1 protein levels were barely detectable in freshly isolated G0 T lymphocytes. Previous work with fibroblasts has suggested that Raf-1 plays a signaling role in the G0-G1 phase transition. In T cells, triggering via the T-cell antigen receptor (TCR)-CD3 complex (TCR/CD3) resulted in an approximately fourfold increase in c-raf-1 mRNA. In addition, the promotion …

Monocytes And Polymorphonuclear Neutrophils Of Patients With Streptococcal Pharyngitis Express Increased Numbers Of Type I Igg Fc Receptors., Paul M. Guyre, A Scott Campbell, Wayne D. Kniffin, Michael W. Fanger Dec 1990

Monocytes And Polymorphonuclear Neutrophils Of Patients With Streptococcal Pharyngitis Express Increased Numbers Of Type I Igg Fc Receptors., Paul M. Guyre, A Scott Campbell, Wayne D. Kniffin, Michael W. Fanger

Dartmouth Scholarship

Studies using cultured cells have shown that gamma interferon (IFN-gamma) induces the expression of Fc gamma RI (the type I Fc receptor for IgG) on human polymorphonuclear neutrophils (PMN) and greatly increases the number of these receptors on human monocytes. Administration of rIFN-gamma in vivo also causes enhanced Fc gamma RI expression on these cell populations. Because streptococcal antigens are potent inducers of IFN-gamma in vitro, we postulated that IFN-gamma would be produced endogenously in vivo in patients with streptococcal infections. Such production of IFN-gamma in vivo, even at low levels, might be expected to induce the expression of Fc …

Home Adaptations For Persons With Chronic Disabilities: An Educational Model., Ruth E. Levine, Laura N. Giltin Oct 1990

Home Adaptations For Persons With Chronic Disabilities: An Educational Model., Ruth E. Levine, Laura N. Giltin

Department of Occupational Therapy Faculty Papers

This paper offers a method by which to train students in the provision of culturally relevant, in-home environmental adaptations for persons with chronic disabilities. On the basis of a theoretical framework, the student therapist learns about the client's life-style and offers adaptations that evolve from a collaborative problem-solving process. The training process has been developed and refined over a 3-year period. A case study illustrates the student's application of theory and practice and the outcome for the client of this service provision approach.

Religion And The Body: Rematerializing The Human Body In The Social Sciences Of Religion, Meredith B. Mcguire Sep 1990

Religion And The Body: Rematerializing The Human Body In The Social Sciences Of Religion, Meredith B. Mcguire

Sociology & Anthropology Faculty Research

The social sciences of religion could be transformed by taking seriously the fact that humans are embodied. A new conceptualization of a mindful body has the potential to lead to profound shifts in how we view our subjects and their worlds. Our research strategies need to take into account that believers (and nonbelievers) are not merely disembodied spirits, but that they experience a material world in and through their bodies. Greater awareness of the social and political uses of human bodies should guide our research and theory.
