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
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
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 …

The majority of cases of childhood typhoid fever diagnosed in the United States occur in persons recently returned from travel abroad. We report two childhood cases of typhoid fever acquired in Mexico and India and diagnosed in an urban United States setting. This report describes these cases and provides insights into the pitfalls in recognizing this condition in a nonendemic setting as well as information concerning differential diagnosis and treatment.

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 …

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.

The purpose of the present study was to empirically identify individuals who differed in their patterns of components derived from the structured interview (SI), and to evaluate whether individuals characterized by the different patterns varied in terms of their risk for coronary heart disease (CHD). The present study represents a reanalysis of data from the Western Collaborative Group Study in which components of Type A were individually related to risk for CHD. Subgroups of individuals who differed in the patterns of their component scores were identified by means of cluster analytic techniques and were found to vary in their risk …

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 …

The Absurdity Of Life, Steven Luper
Philosophy Faculty Research
In "The Absurd"1 Nagel claims that self-conscious human beings are necessarily absurd, so that to escape absurdity while remaining human we would have to cease being self-conscious. fifteen years later, in The View From Nowhere,2 he defends the same thesis, supplementing some of his old arguments with a battery of new ones. I want to suggest that Nagel has misdiagnosed, and exaggerated the inescapability of, our absurdity. He does so partly because the grounds on which he bases his conclusion are spurious, and partly because he does not acknowledge the extent to which we can eliminate absurdity …

Mp92-64 The Stable Fly: A Pest Of Humans And Domestic Animals, Gustave D. Thomas, Steven R. Skoda
University of Nebraska-Lincoln Extension: Historical Materials
Many species of flies are pests. Many people, if you were to ask them about flies, would be at least vaguely aware of the potential to flies to transmit disease organisms. But yet, for the most part, a fly is a fly is a fly. Sayings like "It must be about to rain, the house flies are biting" are still common and show a general need for more, readily accessible information, particularly about some of the pest flies.
Stable flies, obligate blood-feeders, are very important pests to the cattle industry and, at times, are pests to other groups (they're most …

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
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 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, …

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
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 …

We have presented the first child in Delaware with malignant external otitis associated with IgG4 deficiency. Our patient needed three courses of intravenous antibiotics and twice required mastoidectomy, but has recovered completely following the restoration of the natural barrier between the internal and external ear, using a fascial graft from the large temporalis muscle. Some hearing deficit remains.

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
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.
An Experimental Analysis Of Higher-Order Stimulus Control In Humans, Michael B. Gatch
An Experimental Analysis Of Higher-Order Stimulus Control In Humans, Michael B. Gatch
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This dissertation explored sane effects of context on the development of stimulus classes and the transfer of stimulus functions to novel stimuli. The research was also intended to demonstrate the utility of current behavioral theories for prediction and control of contextual effects on class formation. In Experiment lA, contextual control of stimulus classes was established successfully in all six college-student subjects. Matching-to-sample training successfully transferred the function of the contextual stimuli to four novel stimuli, whim resulted in the formation of two three-member classes of contextual stimuli. The first portion of Experiment 1B replicated Experiment 1A with three additional subjects. …

Fibril In Senile Systemic Amyloidosis Is Derived From Normal Transthyretin., Per Westermark, Knut Sletten, Bjorn Johansson, Gibbons G. Cornwell
Dartmouth Scholarship
The amyloid fibril in senile systemic amyloidosis (SSA), like that of familial amyloidotic polyneuropathy, is derived from transthyretin (TTR). SSA, however, is a common disease, affecting to some degree 25% of the population greater than 80 years old. In familial amyloidotic polyneuropathy, the amyloidogenesis has been considered to depend on point mutations leading to TTR variants. We show that the TTR molecule in SSA, on the other hand, has a normal primary structure. Factors other than the primary structure of TTR must therefore be important in the pathogenesis of TTR-derived amyloid.
