Radiation Therapy For Hemangiosarcoma In A Budgerigar, K Freeman, Kevin Hahn, William Adams, Michael Jones, M Petersen Feb 2013

Radiation Therapy For Hemangiosarcoma In A Budgerigar, K Freeman, Kevin Hahn, William Adams, Michael Jones, M Petersen

William H Adams, DVM, DACVR

A swelling on the right metacarpal area of a male budgerigar was diagnosed as hemangiosarcoma. Diagnosis of this malignant endothelial tumor was based on gross and histopathologic findings. The bird was treated with local irradiation of the wing three times weekly for a total of 10 400-cGy fractions. The tumor completely regressed after local irradiation and the budgerigar tolerated the treatment well; however, the bird died 8 weeks later as a result of disseminated disease. Radiation therapy should be considered as a treatment option in birds with tumors that are unlikely to metastasize or that cannot be completely excised.

Fecal Shedding Of Feline Coronavirus In Adult Cats And Kittens In An Abyssinian Cattery, L Harplod, Alfred Legendre, Melissa Kennedy, Paul Plummer, K Millsaps, Barton Rohrbach

Melissa A. Kennedy

15 adult cats and 18 kittens from a single cattery were used to determine patterns of faecal shedding of feline coronavirus (FCV). Blood and faecal samples were collected from adult cats every other month for 13 months. Serum FCV antibody titres were measured using an indirect immunofluorescence assay. A reverse-transcriptase, nested polymerase chain reaction assay was used to detect FCV in faeces. Blood and faecal samples were collected from kittens at approximately 2-week intervals from 3 weeks to 15 weeks of age. Adult cats shed FCV intermittently. All adult cats shed virus in their faeces at least once during the ...

Integration Of Calcium And Cyclic Amp Signaling Pathways By 14-3-3, Chi-Wing Chow, Roger J. Davis Dec 1999

Integration Of Calcium And Cyclic Amp Signaling Pathways By 14-3-3, Chi-Wing Chow, Roger J. Davis

Open Access Articles

Calcium-stimulated nuclear factor of activated T cells (NFAT) transcription activity at the interleukin-2 promoter is negatively regulated by cyclic AMP (cAMP). This effect of cAMP is mediated, in part, by protein kinase A phosphorylation of NFAT. The mechanism of regulation involves the creation of a phosphorylation-dependent binding site for 14-3-3. Decreased NFAT phosphorylation caused by the calcium-stimulated phosphatase calcineurin, or mutation of the PKA phosphorylation sites, disrupted 14-3-3 binding and increased NFAT transcription activity. In contrast, NFAT phosphorylation caused by cAMP increased 14-3-3 binding and reduced NFAT transcription activity. The regulated interaction between NFAT and 14-3-3 provides a mechanism for ...

The Effects Of Anorexia Nervosa On Bone Metabolism In Female Adolescents, Leslie A. Soyka, Steven K. Grinspoon, Lynne L. Levitsky, David B. Herzog, Anne Klibanski

Endocrinology/Diabetes

Osteopenia is a frequent, often persistent, complication of anorexia nervosa (AN) in adolescent girls and occurs during a critical time in bone development. Little is known about bone metabolism in this patient population. Therefore, we measured bone density (BMD) and body composition by dual energy x-ray absorptiometry, nutritional status, bone turnover, calcium, and hormonal status in 19 adolescent girls with AN (mean +/- SEM, 16.0+/-0.4 yr) and 19 bone age-matched controls. The mean duration of AN was 19+/-5 months. Spinal (L1-L4) osteopenia was common in AN. Lumbar anterioposterior BMD was more than 1 SD below the mean ...

Open Access Articles

Developmental control of bone tissue-specific genes requires positive and negative regulatory factors to accommodate physiological requirements for the expression or suppression of the encoded proteins. Osteocalcin (OC) gene transcription is restricted to the late stages of osteoblast differentiation. OC gene expression is suppressed in nonosseous cells and osteoprogenitor cells and during the early proliferative stages of bone cell differentiation. The rat OC promoter contains a homeodomain recognition motif within a highly conserved multipartite promoter element (OC box I) that contributes to tissue-specific transcription. In this study, we demonstrate that the CCAAT displacement protein (CDP), a transcription factor related to the ...

Identification Of The Human Erythrocyte Glucose Transporter (Glut1) Atp Binding Domain: A Dissertation, Kara B. Levine Dec 1999

Identification Of The Human Erythrocyte Glucose Transporter (Glut1) Atp Binding Domain: A Dissertation, Kara B. Levine

GSBS Dissertations and Theses

The human erythrocyte glucose transport protein (GLUT1) interacts with, and is regulated by, cytosolic ATP. This study asks the following questions concerning ATP modulation of GLUT1 mediated sugar transport. 1) Which region(s) of GLUT1 form the adenine nucleotide-binding domain? 2) What factors influence ATP modulation of sugar transport? 3) Is ATP interaction with GLUT1 sufficient for sugar transport regulation?

The first question was addressed through peptide mapping, n-terminal sequencing, and alanine scanning mutagenesis of GLUT1 using [32P]-azidoATP, a photoactivatable ATP analog. We then used a combination of transport measurements and photolabeling strategies to examine how glycolytic intermediates ...

A Study Of Nursing Students And Intrinsic Spirituality, Christine Anderson Madsen Dec 1999

A Study Of Nursing Students And Intrinsic Spirituality, Christine Anderson Madsen

Master's Projects

This paper describes some theoretical perspectives of spirituality, the concepts of spiritual care and spiritual needs, and barriers to providing spiritual care as described in the literature. The two most frequently described barriers are lack of comfort with the topic and lack of education. Because there is so little written about the discussion of spirituality in schools of nursing, a descriptive study using nursing students on the central coast of California was conducted. The Spiritual Involvement and Beliefs Scale (SIBS) was used to measure intrinsic spirituality. This study looked for relationships between the scores on this scale, and the students ...

Recommendations For Standards Regarding Preclinical Neuroprotective And Restorative Drug Development Dec 1999

Recommendations For Standards Regarding Preclinical Neuroprotective And Restorative Drug Development

Open Access Articles

The plethora of failed clinical trials with neuroprotective drugs for acute ischemic stroke have raised justifiable concerns about how best to proceed for the future development of such interventions. Preclinical testing of neuroprotective drugs is an important aspect of assessing their therapeutic potential, but guidelines concerning how to perform preclinical development of purported neuroprotective drugs for acute ischemic stroke are lacking. This conference of academicians and industry representatives was convened to suggest such guidelines for the preclinical evaluation of neuroprotective drugs and to recommend to potential clinical investigators the data they should review to reassure themselves that a particular neuroprotective ...


Analysis Of Cell Polarity Signaling In C. Elegans: A Dissertation, Christian Ernest Rocheleau Dec 1999

Analysis Of Cell Polarity Signaling In C. Elegans: A Dissertation, Christian Ernest Rocheleau

GSBS Dissertations and Theses

During embryonic development of the nematode Caenorhabditis elegans, cell fates are specified by asymmetric segregation of cell fate determinants and via cell-cell signaling events. Specification of the eight-cell stage blastomere E, the endoderm progenitor cell, requires both cell signaling and asymmetric cell division. At the four-cell stage, a polarity-inducing signal from the P2 cell is required for the EMS cell to divide asymmetrically to produce an anterior daughter MS, and posterior daughter E. In the absence of signal, the EMS cell divides symmetrically to produce two daughters that adopt the MS fate. This thesis describes the identification and analyses ...


Occupational Therapists' Interests And Attitudes Toward Animal Assisted Therapy As A Treatment Modality, Lori Susan Buckley Dec 1999

Occupational Therapists' Interests And Attitudes Toward Animal Assisted Therapy As A Treatment Modality, Lori Susan Buckley

FIU Electronic Theses and Dissertations

One hundred seventy-nine occupational therapists (OTs) responded to a survey regarding their interests and attitudes toward animal assisted therapy as a treatment modality. It was found that most of the practitioners would be interested in learning more about animal assisted therapy and most felt it is a valid treatment modality to be used by occupational therapists. Furthermore, the most common answer to the question "why would you not be interested in participating in an AAT program," was "I feel I don't know enough about it". It was also found that therapists' most commonly selected patient goals for AAT were ...

Genetic Control Of Eye Development, A Case Study Focused On The Murine Mutation Belly Spot And Tail (Bst), Qing Tang Dec 1999

Genetic Control Of Eye Development, A Case Study Focused On The Murine Mutation Belly Spot And Tail (Bst), Qing Tang

Theses and Dissertations (ETD)

Development of the eye is controlled by a network of genes, often conserved, that regulate the timing and location of cellular differentiation. One approach to understanding this network of genes and their interaction is to focus on mutations, spontaneous or induced, that predictably disrupt the proper function of such networks, and by examining the effect of such disruption on the function of other genes.

The Belly spot and tail (Bst) semi-dominant mutation, mapped to mouse Chromosome 16, leads to developmental defects of the eye, skeleton, and coat pigmentation. In the eye, the mutant phenotype is characterized by the presence of ...


Venous Leg Ulcer Treatment: Why Won't The Patient Comply?, Jill Sparks Dec 1999

Venous Leg Ulcer Treatment: Why Won't The Patient Comply?, Jill Sparks

Theses Masters Coursework

Community nurses spend much of their time in the treatment and prevention of recurrence of venous leg ulcers. Failure by patients to follow treatment regimes that include compression therapy, diet, exercise and leg elevation is the source of much frustration for community nurses who are quick to label these patients as "non-compliant". Why is it that some patients will adopt health behaviours that are beneficial for the healing of venous leg ulcers and other patients will not? What can community nurses do to encourage participation in the above, self-care activities? A complex relationship between multiple factors that influence patients' decisions ...

Stress Experienced By Respite Care Workers And Family Caregivers When Caring For Alzheimer's Patients, Monica D. Minewiser

Theses & Dissertations

Changing demographics and cost containment in health care in caring for the Alzheimer's Disease (AD) patient has given birth to a growing need for respite care workers. The purpose of the study was to determine whether the stress level of a respite care worker who works with an AD patient in a noninstitutionalized setting on a daily basis will be significantly less than that of a family caregiver when caring for an AD patient. The Revised Memory and Behavior Problem Checklist (RMBPC) was the instrument used to measure stress. This is a questionnaire consisting of 24 questions and allows ...


Using Professionally Trained Actors In Social Work Role-Play Simulations, Helen E. Petracchi Dec 1999

Using Professionally Trained Actors In Social Work Role-Play Simulations, Helen E. Petracchi

The Journal of Sociology & Social Welfare

The literature available to social work educators contains limited discussion of the use of role play simulation in the classroom. This paper presents the experiences of first-year MSW students in a foundation generalist practice class who were evaluated using role play for their final examination. In a unique arrangement, clients in these simulations were role-played by firstyear acting students from the university's theater arts department. The reaction of the social work students to role play with professionally trained actors is described and discussed from voluntarily submitted descriptions of the experience.


Officer Involved Shooting: The Emotional Impact And The Effective Coping Strategies, Patrick P. Charoen Dec 1999

Officer Involved Shooting: The Emotional Impact And The Effective Coping Strategies, Patrick P. Charoen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The emotional impact of a shooting incident on the individual police officer has been recognized and detailed by both police and mental health professionals (Lippert & Ferrara, 1984). The human cost and financial costs to Police Departments as a result of "post shooting" trauma has sensitized many departments to the need for professional support for officers involved in shootings. Recent survey research has provided information about the percentage of officers who experienced great, moderate, or no emotional impact after being involved in shootings (Stratton, 1982). However, information about the degree to which police departments have responded to this need has been ...


Economic Impact Of A Ban On The Use Of Over-The-Counter Antibiotics, Dermot J. Hayes, Helen H. Jensen, Lennart Backstrom, Jay Fabiosa Dec 1999

Economic Impact Of A Ban On The Use Of Over-The-Counter Antibiotics, Dermot J. Hayes, Helen H. Jensen, Lennart Backstrom, Jay Fabiosa

CARD Staff Reports

Because antibiotic drugs are widely used in starter, grower, finishing, and sow feeds, a ban on their use would impact pork production processes and practices, and therefore would have an economic impact on the U.S. pork industry and pork market. This study considers the economic effects of a ban in pork production, with no change of regulation on other meats. The authors examine the evidence from a range of cases from Sweden to describe what is most likely to occur if a ban on antibiotic drugs in pork production were to be implemented in the United States.
