Evaluation Of Accelerated Plethysmography As A Measure Of Health And Fitness, Angela Marie Humble Dec 1997

Evaluation Of Accelerated Plethysmography As A Measure Of Health And Fitness, Angela Marie Humble

Dissertations and Theses

Plethysmography is a technique used for measuring alterations in the volume of organs or limbs. Japanese researchers have developed a relatively new application of plethysmography (accelerated plethysmography) that uses information from the pulse wave measured at the fingertip to make inferences about health and fitness status. The instrument used to collect data -- the Precaregraph (accelerated plethysmograph) -- provides an accelerated pulse waveform and and APG index, a mathematical representation of the waveform. It was the purpose of this study to evaluate the validity of the Precaregraph by examining the relationship between the APG index and previously validated measures of …


A Linkage Map Of The Canine Genome, Cathryn Mellersh, Amelia Langston, Gregory Acland, Melissa Fleming, Kunal Ray, Neil Weigand, Leigh Francisco, Mark Gibbs, Gustavo Aguirre, Elaine Ostrander Dec 1997

A Linkage Map Of The Canine Genome, Cathryn Mellersh, Amelia Langston, Gregory Acland, Melissa Fleming, Kunal Ray, Neil Weigand, Leigh Francisco, Mark Gibbs, Gustavo Aguirre, Elaine Ostrander

Gustavo D. Aguirre, VMD, PhD

A genetic linkage map of the canine genome has been developed by typing 150 microsatellite markers using 17 three-generation pedigrees, composed of 163 F2individuals. One hundred and thirty-nine markers were linked to at least one other marker with a lod score ≥ 3.0, identifying 30 linkage groups. The largest chromosome had 9 markers spanning 106.1 cM. The average distance between markers was 14.03 cM, and the map covers an estimated 2073 cM. Eleven markers were informative on the mapping panel, but were unlinked to any other marker. These likely represent single markers located on small, distinct canine chromosomes. This map …


Construction Of A Panel Of Canine–Rodent Hybrid Cell Lines For Use In Partitioning Of The Canine Genome, Amelia A. Langston, Cathryn S. Mellersh, Cassandra L. Neal, Kunal Ray, Gregory M. Acland, Mark Gibbs, Gustavo D. Aguirre, R.E. K. Fournier, Elaine A. Ostrander Dec 1997

Construction Of A Panel Of Canine–Rodent Hybrid Cell Lines For Use In Partitioning Of The Canine Genome, Amelia A. Langston, Cathryn S. Mellersh, Cassandra L. Neal, Kunal Ray, Gregory M. Acland, Mark Gibbs, Gustavo D. Aguirre, R.E. K. Fournier, Elaine A. Ostrander

Gustavo D. Aguirre, VMD, PhD

We have constructed a collection of canine–rodent microcell hybrid cell lines by fusion of canine fibroblast microcell donors with immortalized rodent recipient cells. Characterization of the hybrid cell lines using a combination of fluorescencein situhybridization and PCR analysis of canine microsatellite repeat sequences allowed selection of a panel of hybrids in which most canine chromosomes are represented. Approximately 90% of genetic markers and genes that were tested could be assigned to 1 of 31 anonymous canine chromosome groups, based on common patterns of retention in the hybrid set. Many of these putative chromosome groups have now been validated …

Examination Of Benefits Of Binaural Auditory Stimulation For Children With A Cochlear Implant And A Hearing Aid In The Contralateral Ear, Evonne Nicol Altesleben Dec 1997

Examination Of Benefits Of Binaural Auditory Stimulation For Children With A Cochlear Implant And A Hearing Aid In The Contralateral Ear, Evonne Nicol Altesleben

Dissertations and Theses

Congenital or acquired hearing impairments put children at risk of delayed language development. Today the cochlear implant (Cl) is a viable amplification option for some children with profound hearing losses. Audiologists often recommend that children with hearing impairments be fitted with binaural hearing aids in the hope that maximum stimulation will occur and that auditory deprivation will be lessened. An area lacking investigation is whether binaural stimulation will be beneficial to the cochlear implant recipient.Controversy also exists regarding the use of a hearing aid in the non-implanted ear.

The focus of this study was to compare binaural auditory stimulation benefits …


Further Characterization Of A Complement-Sensitive Mutant Of A Virulent Avian Escherichia Coli Isolate, Theodore J. Kottom, Lisa K. Nolan, Michael Robinson, John Brown, Tom Gustad, Shelley M. Horne, Catherine W. Giddings Dec 1997

Further Characterization Of A Complement-Sensitive Mutant Of A Virulent Avian Escherichia Coli Isolate, Theodore J. Kottom, Lisa K. Nolan, Michael Robinson, John Brown, Tom Gustad, Shelley M. Horne, Catherine W. Giddings

Lisa K. Nolan

An attempt was made to characterize the mechanism of complement resistance operating in a virulent avian Escherichia coli isolate. Using flow cytometry to detect antibody to C3, we found that there was significantly more antibody bound to a complement-sensitive mutant of this wild type than to the parent organism, suggesting that more C3 subunits were bound to the wild type. Neither the wild type nor the mutant degraded C3. Further, the mutant was phagocytosed to a significantly greater degree than the wild type by cultured phagocytes in the presence of C5-deficient serum. These data suggest that the wild type is …


A Highly Adherent Phenotype Associated With Virulent Bvg+-Phase Swine Isolates Of Bordetella Bronchiseptica Grown Under Modulating Conditions, Karen B. Register, Mark R. Ackermann Dec 1997

A Highly Adherent Phenotype Associated With Virulent Bvg+-Phase Swine Isolates Of Bordetella Bronchiseptica Grown Under Modulating Conditions, Karen B. Register, Mark R. Ackermann

Mark R. Ackermann

The ability of Bvg(-)-phase and Bvg(+)-phase Bordetella bronchiseptica swine isolates, grown under modulating or nonmodulating conditions, to adhere to swine ciliated nasal epithelial cells was determined. When virulent strains were cultivated at 37 degrees C in the Bvg+ phase, numerous adherent bacteria (approximately eight per cell, depending on the strain used) were observed. However, when such strains were grown under modulating conditions (23 degrees C), a significant increase in the level of attachment was seen, suggesting that B. bronchiseptica produces a Bvg-repressed adhesin under these conditions. bvg mutant strains, including an isogenic bvgS mutant, adhered minimally. Western blots indicated that …


A Grounded Theory Analysis Of The Knowledge And Skills Of Wound Care Nurses, Geraldine Crawley Dec 1997

A Grounded Theory Analysis Of The Knowledge And Skills Of Wound Care Nurses, Geraldine Crawley

Theses Masters Coursework

Major changes in wound care practices have occurred in recent years because of increased inquiry into the biology and physiology of wounds. Nurses are having difficulty keeping up with these changes which leads to knowledge being applied inconsistently in practice.

This study investigated what knowledge nurses use when practicing wound care, from a grounded theory perspective. By examining the social processes involved in nursing behaviour and the context from which these processes emerge, an explanation is given for the meaning of these experiences for nurses.

The substantive theory derived from this research informs nursing, its body of knowledge and future …


Interaction Of Gaba And Excitatory Amino Acids In The Basolateral Amygdala: Role In Cardiovascular Regulation, Robert P. Soltis, Jennifer C. Cook, Adam E. Gregg, Brian J. Sanders Dec 1997

Interaction Of Gaba And Excitatory Amino Acids In The Basolateral Amygdala: Role In Cardiovascular Regulation, Robert P. Soltis, Jennifer C. Cook, Adam E. Gregg, Brian J. Sanders

Scholarship and Professional Work – COPHS

Activation of the amygdala in rats produces cardiovascular changes that include increases in heart rate and arterial pressure as well as behavioral changes characteristic of emotional arousal. The objective of the present study was to examine the interaction of GABA and excitatory amino acid (EAA) receptors in the basolateral amygdala (BLA) in regulating cardiovascular function. Microinjection of the GABAA receptor antagonist bicuculline methiodide (BMI) or the E A A receptor agonists NMDA or AMPA into the same region of the BLA of conscious rats produced dose-related increases in heart rate and arterial pressure. Injection of the nonselective EAA receptor …

The Relationship Between Childhood Aggression And Impulsiveness, Mary Gail Glover Dec 1997

The Relationship Between Childhood Aggression And Impulsiveness, Mary Gail Glover

College of Arts & Sciences

Previous research on the relationship between children's levels of aggression and impulsivity have been inconclusive. Studies of each of these behaviors independently have shown that they are correlated with many of the same factors. However, no studies have been found in which aggression and impulsivity have correlated specifically with each other. The purpose of the present study was to determine if a relationship exists between aggression and impulsivity in children. The participants of this study consisted of 115 children who had been tested at a center for behavioral analysis to determine diagnoses of Attention-Deficit/Hyperactivity Disorder. They had been referred for …

Alterations In Calcium Homeostasis And The Insulin-Like Growth Factor Signaling Pathway Induced By Carcinogenic Polycyclic And Halogenated Aromatic Hydrocarbons In Human Mammary Epithelial Cells, Stacey L. Tannheimer Dec 1997

Alterations In Calcium Homeostasis And The Insulin-Like Growth Factor Signaling Pathway Induced By Carcinogenic Polycyclic And Halogenated Aromatic Hydrocarbons In Human Mammary Epithelial Cells, Stacey L. Tannheimer

Pharmaceutical Sciences ETDs

Breast cancer is a major health concern for women, with only a small percent of the risk factors currently identified. It has been estimated that environmental factors may contribute to up to 80% of breast cancer cases. Many environmental carcinogens, such as polycyclic and halogenated aromatic hydrocarbons (PAHs and HAHs), are proven mammary carcinogens in animal models. Therefore, these studies were conducted to elucidate potential roles of PAHs and HAHs in alterations in known signaling pathways in human mammary epithelial cells (HMEC). Carcinogenic PAHs have previously been shown to produce sustained alterations in the calcium (Ca2') homeostasis of lymphocytes Therefore, …


Characteristics And Resource Utilization Of Patients Of A Proprietary Home Health Agency In Rural South Central Kentucky, Linda Sewell Dec 1997

Characteristics And Resource Utilization Of Patients Of A Proprietary Home Health Agency In Rural South Central Kentucky, Linda Sewell

Masters Theses & Specialist Projects

The home health industry's introduction to managed care raises the prospect of reduced access to health care and poor outcomes for a vulnerable segment of our population—the rural elderly. Before effective intervention strategies can be accurately evaluated, a clearer picture of the sociodemographic features and home care service consumption is needed for this understudied group. The study was intended to provide a basis for future research into the evaluation of alternative methods of delivering effective care in terms of outcome and decreased cost for this population. A retrospective descriptive analysis was made of the patient record for the first six …


Perceived Differences Between Male And Female Occupational Therapists’ Treatment And Other Related Gender Issues, Dennis Robert Jones Dec 1997

Perceived Differences Between Male And Female Occupational Therapists’ Treatment And Other Related Gender Issues, Dennis Robert Jones

Masters Theses

This study explored how occupational therapy clients perceive the treatment they receive from male and female occupational therapists. The study was conducted in a qualitative manner. Occupational therapy supervisors who have supervised both female and male occupational therapists were interviewed to gain an initial understanding of the relevant issues. More structured interviews were then conducted with clients who have been treated by both a female and a male occupational therapist. Therapists and clients were also observed during four treatment sessions.

Analysis of the data collected through interviews revealed that supervisors and clients do notice some behavioral differences in male and …

The Effects Of Animal Assisted Therapy When Used As An Adjunct To Occupational Therapy In The Rehabilitation Of Persons Who Have Had Cerebral Vascular Accidents, Alice Arlene Briggs Dec 1997

The Effects Of Animal Assisted Therapy When Used As An Adjunct To Occupational Therapy In The Rehabilitation Of Persons Who Have Had Cerebral Vascular Accidents, Alice Arlene Briggs

Masters Theses

Occupational therapists can use animals to assist their clients in achieving goals in treatment. Most often dogs are used as they are more easily trained. The dog may fetch a ball thrown by the client or stand still and allow the client to brush it. These activities with the animal increase the client's range of motion, endurance and strength. Dogs as well as other animals are used in various ways to elicit the desired response from the client. No studies were found in the literature that examined the use of animals as adjuncts to, or as modalities in occupational therapy …


Cultural Considerations In Clinical Reasoning: An Occupational Therapy Case Study, Sandra M. Winter Dec 1997

Cultural Considerations In Clinical Reasoning: An Occupational Therapy Case Study, Sandra M. Winter

Masters Theses

This study looked at an occupational therapist's work with clients from varied cultural backgrounds. Qualitative research strategies and a phenomenological approach were used to gather data through interviews with a single respondent and observation of treatment. This methodology was used to examine the process utilized to acquire cultural knowledge and integrate that knowledge into treatment planning. Research focused on: (a) how the cultural background of a client influenced an occupational therapist as she planned and implemented treatment, (b) how the treatment process was influenced by cultural differences between the therapist and the client, and (c) how training or education helped …

Narrative Development In Late Talkers: Early School Age, Rhea Paul, Rita Hernandez, Lisa Taylor, Karen Johnson

Communication Disorders Faculty Publications

Children with slow expressive language development (SELD) as toddlers and a control group of children with normal language development (NL) were followed to early school age. Children with SELD were, at that point, subdivided into two groups: those who had moved within the normal range of expressive language (the History of Expressive Language Delay [HELD] subgroup); and those who continued to score below the normal range in expressive language at school age (the Expressive Language Delay [ELD] subgroup). During their kindergarten, first, and second grade years, they were administered a narrative generation task. Narratives were analyzed for MLU, lexical diversity, …

Direct Demonstration Of Retroviral Recombination In A Rhesus Monkey, Dawn P. Wooley, Randall A. Smith, Susan Czajak, Ronald C. Desrosiers Dec 1997

Direct Demonstration Of Retroviral Recombination In A Rhesus Monkey, Dawn P. Wooley, Randall A. Smith, Susan Czajak, Ronald C. Desrosiers

Neuroscience, Cell Biology & Physiology Faculty Publications

Recombination may be an important mechanism for increasing variation in retroviral populations. Retroviral recombination has been demonstrated in tissue culture systems by artificially creating doubly infected cells. Evidence for retroviral recombination in vivo is indirect and is based principally on the identification of apparently mosaic human immunodeficiency virus type 1 genomes from phylogenetic analyses of viral sequences. We infected a rhesus monkey with two different molecularly cloned strains of simian immunodeficiency virus. One strain of virus had a deletion in vpx and vpr, and the other strain had a deletion in nef. Each strain on its own induced low virus …

Locus Of Control, Activity Level, And Living Situation Among The Elderly, Jennifer L. Birchenough

Masters Theses

The focus of this study was to investigate the relationships among locus of control, activity level, and living situation in the elderly. The participants in this study consisted of 62 elderly individuals who resided in one of three living situations: (1) independent living, (2) assisted living, and (3) comprehensive care centers. All participants were screened for cognitive status using the Mini-Mental State Assessment (Folstein, M., Folstein, S., & McHugh, 1975). Individuals who scored in the normal range then completed a Locus of Control Scale (Rotter, 1966) and the Index of Occupational Behavior (Gregory, 1983) to address the meaningfulness of, and …


A Dichotomous Role For Nitric Oxide During Acute Toxoplasma Gondii Infection In Mice, Imtiaz A. Khan, Joseph D. Schwartzman, Tadashi Matsuura, Lloyd H. Kasper Dec 1997

A Dichotomous Role For Nitric Oxide During Acute Toxoplasma Gondii Infection In Mice, Imtiaz A. Khan, Joseph D. Schwartzman, Tadashi Matsuura, Lloyd H. Kasper

Dartmouth Scholarship

Production of nitric oxide by macrophages is believed to be an important microbicidal mechanism for a variety of intracellular pathogens, including Toxoplasma gondii. Mice with a targeted disruption of the inducible nitric oxide synthase gene (iNOS) were infected orally with T. gondii tissue cysts. Time to death was prolonged compared with parental controls. Histologic analysis of tissue from infected mice showed scattered small foci of inflammation with parasites in various tissues of iNOS−/− mice, whereas tissue from the parental C57BL/6 mice had more extensive tissue inflammation with few visible parasites. In particular, extensive ulceration and necrosis of distal small …


The Biography Of A Scale: Contextual Factors That Influence The Measurement Of Family Functioning, Ludwig Geismar Dec 1997

The Biography Of A Scale: Contextual Factors That Influence The Measurement Of Family Functioning, Ludwig Geismar

The Journal of Sociology & Social Welfare

The subject of instrument relevance is addressed by examining issues that have arisen in the use of a single scale over a forty year period. The issues revolve around the impact of varying social conditions, changing ethos, differential respondent receptiveness, and evolving research technology. Extended use of an instrument, it is argued, yields information that transcends the conventional techniques for testing instrument adequacy. The lack of opportunities in social work for accessing information on extended use of measurement tools is due, among other factors, to a preoccupation with working on subjects that are new and original and to a lack …
