Dengue Virus-Specific Cross-Reactive Cd8+ Human Cytotoxic T Lymphocytes, Jack F. Bukowski, Ichiro Kurane, Ching-Juh Lai, Michael Bray, Barry Falgout, Francis A. Ennis Dec 1989

Dengue Virus-Specific Cross-Reactive Cd8+ Human Cytotoxic T Lymphocytes, Jack F. Bukowski, Ichiro Kurane, Ching-Juh Lai, Michael Bray, Barry Falgout, Francis A. Ennis

Open Access Articles

Stimulation with live dengue virus of peripheral blood mononuclear cells from a dengue virus type 4-immune donor generated virus-specific, serotype-cross-reactive, CD8+, class I-restricted cytotoxic T lymphocytes (CTL) capable of lysing dengue virus-infected cells and cells pulsed with dengue virus antigens of all four serotypes. These CTL lysed autologous fibroblasts infected with vaccinia virus-dengue virus recombinant viruses containing the E gene or several nonstructural dengue virus type 4 genes. These results demonstrate that both dengue virus structural and nonstructural proteins are targets for the cytotoxic T-cell-mediated immune response to dengue virus and suggest that serotype-cross-reactive CD8+ CTL may be important mediators ...


Simian Virus 40 Host Range/Helper Function Mutations Cause Multiple Defects In Viral Late Gene Expression., Terryl Stacy, Michele Chamberlain, Charles N. Cole Dec 1989

Simian Virus 40 Host Range/Helper Function Mutations Cause Multiple Defects In Viral Late Gene Expression., Terryl Stacy, Michele Chamberlain, Charles N. Cole

Open Dartmouth: Faculty Open Access Articles

Simian virus 40 (SV40) deletion mutants dlA2459 and dlA2475 express T antigens that lack the normal carboxy terminus. These mutants are called host range/helper function (hr/hf) mutants because they form plaques at 37 degrees C on BSC-1 and Vero monkey kidney cell lines but not on CV-1p monkey kidney cells. Wild-type SV40 can provide a helper function to permit growth of human adenoviruses in monkey kidney cells; the hr/hf mutants cannot. Progeny yields of hr/hf mutants are also cold sensitive in all cell lines tested. Patterns of viral macromolecular synthesis in three cell lines (Vero, BSC-1 ...


Continuous Passive Motion After Knee Arthroscopy, Lisa Bauman Dec 1989

Continuous Passive Motion After Knee Arthroscopy, Lisa Bauman

Master's Theses

The purpose of the study was to investigate the effect of continuous passive motion (CPM) after arthroscopy. A CPM machine was used one hour following knee surgery. Statistical analysis was performed to determine differences in knee range of motion (ROM), strength and circumference, at time intervals preoperatively, one, seven, and twenty-eight days following surgery. The analysis of variance revealed no significant difference between the CPM and control groups for any parameter. A significant interaction effect between treatment and time was demonstrated one day after surgery for extension, joint line circumference, and midthigh circumference; and 28 days after surgery for the ...


An Investigation Of Pitch Perturbation And Vocal Intensity Characteristics Of Stutterers And Nonstutterers, Carmen M. Bamberg Dec 1989

An Investigation Of Pitch Perturbation And Vocal Intensity Characteristics Of Stutterers And Nonstutterers, Carmen M. Bamberg

Master's Theses

Pitch and amplitude perturbation values were compared for nine adult stutterers and nine adult nonstutterers. Each subject produced ten sustained phonations of the vowels /a/ and /i/. An automatic pitch-synchronous autocorrelation fundamental frequency tracker was used to extract period and amplitude measures.

Findings revealed that: (a) stutterers had significantly more vocal shimmer than nonstutterers (p = .01), (b) F-ratios for percent jitter between groups approached (p = .07) but did not reach significance, and (c) the vowel /a/ was produced with higher levels of jitter and shimmer than the vowel /i/. Results support the notion that instability of the vocalization process is ...


The Effects Of Added Purpose On Fine Motor Performance In Learning Disabled Children, Sarah Lynn Austin Dec 1989

The Effects Of Added Purpose On Fine Motor Performance In Learning Disabled Children, Sarah Lynn Austin

Master's Theses

The idea that occupations which offer added levels of purpose elicit a high quality of performance is widely accepted within occupational therapy. In this experiment involving fine motor performance, fifty-three learning disabled children were randomly assigned to two groups. It was hypothesized that children cutting out a circle, presented as a wheel which would complete a paper truck, would cut more accurately than those who cut out the same circle without the suggestion of it being used as a wheel. Accuracy was assessed by measuring the area of the children's cutting errors. The experimental design included the use of ...


Leisure Satisfaction Of Alcoholics And Cocaine Addicts, Tamera F. Stanback Dec 1989

Leisure Satisfaction Of Alcoholics And Cocaine Addicts, Tamera F. Stanback

Master's Theses

A role for occupational therapists is to help substance abuse clients achieve a healthy balance across occupational performance areas, including leisure. The literature suggests that alcoholics have deficits in leisure, but cocaine addicts have not yet been studied systematically in terms of leisure. This study compared twenty alcoholics from two Midwestern in-patient treatments centers to fourteen unmatched cocaine addicts at the same centers in terms of their leisure satisfaction. Then, nine male subjects from each group were matched in terms of age and family status, and t-test comparisons were made once again. The Leisure Satisfaction Scale was used as a ...

Post-Transcriptional Regulation Of Glutathione Peroxidase Gene Expression By Selenium In The Hl-60 Human Myeloid Cell Line, Sunil Chada, Constance Whitney, Peter E. Newburger Nov 1989

Post-Transcriptional Regulation Of Glutathione Peroxidase Gene Expression By Selenium In The Hl-60 Human Myeloid Cell Line, Sunil Chada, Constance Whitney, Peter E. Newburger

Open Access Articles

We have used a cloned cDNA for the major human selenoprotein, glutathione peroxidase (GPx), to assess the mode of regulation of human GPx gene (GPX-1) expression by selenium. When the HL-60 human myeloid cell line is grown in a selenium-deficient medium, GPx enzymatic activity decreases 30-fold compared with selenium-replete cells. Upon return to a medium containing selenium in the form of selenite, GPx activity in the cells starts to increase within 48 hours and reaches maximal (selenium-replete) levels at 7 days. Steady-state immunoreactive protein levels correlate with enzymatic activity. Cycloheximide inhibits the rise in GPx activity that accompanies selenium replenishment ...

Comparisons Of Cutoff And Regression-Based Definitions Of Reading Disabilities, J. M. Fletcher, K. A. Espy, D. J. Francis, K. C. Davidson, B. P. Rourke, S. A. Shaywitz Nov 1989

Comparisons Of Cutoff And Regression-Based Definitions Of Reading Disabilities, J. M. Fletcher, K. A. Espy, D. J. Francis, K. C. Davidson, B. P. Rourke, S. A. Shaywitz

Developmental Cognitive Neuroscience Laboratory - Faculty and Staff Publications

Investigated specificity in reading disability by comparing 2 approaches to defining and selecting children with reading disabilities. One approach defined reading disability according to cutoff scores representing appropriate levels of intelligence and reading deficiency, whereas the other approach adjusted these scores for their intercorrelation through regression procedures. Results reveal differences in which of 1,069 children (aged 9-14 yrs) were identified as reading disabled, depending on the definition used. However, differences in neuropsychological performance between Ss whose reading scores were discrepant or not discrepant with their IQ scores were small and nonspecific for both definitions.


Occupational Therapy In Early Intervention: A Family-Centered Approach., Roseann C. Schaaf, L L. Mulrooney Nov 1989

Occupational Therapy In Early Intervention: A Family-Centered Approach., Roseann C. Schaaf, L L. Mulrooney

Department of Occupational Therapy Faculty Papers

This article describes a framework for occupational therapy service provision in early intervention settings and presents pilot data aimed at examining the framework's effectiveness. The Family-Centered Framework for Early Intervention is a synthesis of concepts from the Model of Human Occupation (Kielhofner & Burke, 1980) and from the literature on play. It encompasses a systematic, holistic approach that considers the child and the family within the context of their life environments. In this framework, play is used both as an evaluative tool and as an intervention modality that addresses the volition, habituation, and performance of the child and family as ...

Breast Cancer Screening By Mammography: Utilization And Associated Factors, Jane G. Zapka, Anne M. Stoddard, Mary E. Costanza, Harru L. Greene Jr.

Women’s Health Research Faculty Publications

The status of mammography screening experience and factors related to utilization were examined in six towns serviced by physician staffs at five hospitals. Data were collected via random digit dial telephone interview of a probability sample of 1184 women, aged 45-75 years. The results showed that 55% of the women reported ever having had a mammogram. Of those who had ever had a mammogram, 21% reported that the mammogram in the past year was their first one. Of those women who are over 50 and had ever had a mammogram, 57% reported one in the past year. Analyses demonstrated that ...


Complex Motor Dynamics And Control In Multi-Looped Negative Feedback Systems, Anne Beuter, John Milton, Christiane Labrie, Leon Glass Nov 1989

Complex Motor Dynamics And Control In Multi-Looped Negative Feedback Systems, Anne Beuter, John Milton, Christiane Labrie, Leon Glass

WM Keck Science Faculty Papers

Experiments were performed in normal and Parkinsonian subjects who were asked to maintain a constant finger position using time-delayed visual feedback. The finger position showed complex dynamics, with characteristic differences between normal and Parkinosonian subjects. Here we discuss some of the theoretical issues that must be resolved in order to understand the mechanisms that underlie the generation of these complex signals.


Significance Of Premature Stop Codons In Env Of Simian Immunodeficiency Virus, Toshiaki Kodama, Dawn P. Wooley, Yathirajulu M. Naidu, Harry W. Kestler Iii, Muthiah D. Daniel, Yen Li, Ronald C. Desrosiers Nov 1989

Neuroscience, Cell Biology & Physiology Faculty Publications

The location of the translational termination codon for the transmembrane protein (TMP) varies in three infectious molecular clones of simian immunodeficiency virus from macaques (SIVmac). The SIVmac251 and SIVmac142 infectious clones have premature stop signals that differ in location by one codon; transfection of these DNAs into human HUT-78 cells yielded virus with a truncated TMP (28 to 30 kilodaltons [kDa]). The SIVmac239 infectious clone does not have a premature stop codon in its TMP-coding region. Transfection of HUT-78 cells with this clone initially yielded virus with a full-length TMP (41 kDa). At ...

Linker Insertion Mutants Of Simian Virus 40 Large T Antigen That Show Trans-Dominant Interference With Wild-Type Large T Antigen Map To Multiple Sites Within The T-Antigen Gene., Jiyue Y. Zhu, Charles N. Cole Nov 1989

Linker Insertion Mutants Of Simian Virus 40 Large T Antigen That Show Trans-Dominant Interference With Wild-Type Large T Antigen Map To Multiple Sites Within The T-Antigen Gene., Jiyue Y. Zhu, Charles N. Cole

Open Dartmouth: Faculty Open Access Articles

Linker insertion mutants affecting the simian virus 40 (SV40) large tumor (T) antigen were constructed by inserting a 12-base-pair oligonucleotide linker into restriction endonuclease cleavage sites located within the early region of SV40. One mutant, with the insertion at amino acid 5, was viable in CV-1p and BSC-1 cells, indicating that sequences very close to the amino terminus of large T could be altered without affecting the lytic infection cycle of SV40. All other mutants affecting large T were not viable. In complementation assays between the linker insertion mutants and either a late-gene mutant, dlBC865, or a host range/helper ...


Detection Of Hiv-1-Infected Cells From Patients Using Nonisotopic In Situ Hybridization, Robert H. Singer, Kevin S. Byron, Jeanne B. Lawrence, John L. Sullivan Nov 1989

Detection Of Hiv-1-Infected Cells From Patients Using Nonisotopic In Situ Hybridization, Robert H. Singer, Kevin S. Byron, Jeanne B. Lawrence, John L. Sullivan

Open Access Articles

We have demonstrated that a sensitive, nonisotopic in situ hybridization (ISH) assay can be used to detect HIV-infected cells from seropositive, asymptomatic individuals. Our assay is based on the detection of a biotinated HIV DNA probe hybridized to human immunodeficiency virus (HIV)-infected peripheral blood lymphocytes (PBL) using streptavidin and alkaline phosphatase to identify positive cells. This assay is rapid in that it can be performed within a day and is sensitive enough to unambiguously identify a rare, single, positive cell. Patient samples derived from HIV-seropositive hemophiliacs and HIV-seropositive infants were analyzed before and after coculture with normal PBL. The ...


Ethical Decision Making By British General Practitioners, Ronald Christie, Charles Freer, Barry Hoffmaster, Moira Stewart Oct 1989

Ethical Decision Making By British General Practitioners, Ronald Christie, Charles Freer, Barry Hoffmaster, Moira Stewart

C. Barry Hoffmaster

General practitioners in England and Wales were sent a questionnaire asking how they would handle the ethical problems posed by six case vignettes and their reasons for their decisions. The ethical problems included: how much information to divulge to patients, how extensively a physician should become involved in the lifestyles of patients and how to deal with a possible family problem. The varying patterns of response to the six cases suggested that ethical issues are resolved in a case-by-case, not a theoretical, basis.
