A Qualitative Study Of The Impact Of Hip Fracture In The Elderly Population, Stephanie Anne Price

Theses: Doctorates and Masters

The social, emotional and economic impact of falling in the elderly population is significant. Falls are the leading cause of injury related deaths and hospitalisation amongst people aged 65 years and older, a major factor in their morbidity and mortality rates. Post fall sequelae can have major ramifications that include reduction or avoidance of activities, attributable to an enduring fear of future falls. Twenty-three older people who had fallen in the community were located via hospital records and invited to participate in the study. Subjective accounts of the impact of falling and sustaining a hip fracture were obtained by means …

Detection And Modeling Of Radiation Induced Effects In Tissues By Dielectric Spectroscopy, Dorin A. Todor

Physics Theses & Dissertations

The work presented here is applied physics research in the field of radiation treatment. We address the development of a new and innovative method, in vivo and possibly non-invasive, for tumor and healthy tissues control during and after the radiation treatment. The radiation treatment is delivered in an almost standardized manner for particular classes of tumors. The large variance in the individual radio sensitivity of healthy tissues and tumors often leads to local recurrence of neoplastic growth and/or distant metastatic disease which often remains untreated. The method is based on the measurement and analysis of electrical impedance data in …

Increasing Readiness To Change Among Smokers In A Primary Care Setting, Sheila F. Collicott

Psychology Theses & Dissertations

This study compared the effectiveness of two brief interventions, direct advice and motivational interviewing, for increasing motivation to quit among male smokers in the pre-contemplation and contemplation stages of change who were primary care patients at an Eastern urban VA medical center. Contrary to expectations, participants receiving motivational interviews did not increase more in readiness to change, motivation, and actions to quit, than those receiving direct advice or a control conversation, nor did they smoke fewer cigarettes per day. As expected, contemplators reported more cutting down and quit attempts than pre-contemplators. Factors that may have limited the effectiveness of interventions …

Telomerase Activity In Human Preimplantation Embryos, Diane Lynne Wright

Theses and Dissertations in Biomedical Sciences

Telomerase, a ribonucleoprotein, has been described as an essential component of highly proliferative cells, which stabilizes the telomeres and avoids cellular senescence. Telomerase has been identified in various embryonic cell stages, hematopoietic cells, and in >85% of tumor tissue biopsies analyzed. The ability to measure the potential to proliferate successfully could provide an objective measure of an embryo's quality. The objectives of this study were to modify the telomeric repeat amplification protocol (TRAP) assay system for increased sensitivity to allow detection of telomerase activity in the single cell of an oocyte and embryo, obtain telomerase activity levels for the oocyte …

Sterilization In The United States: Prevalence And Controversies, Carey Brown

Masters Theses & Specialist Projects

There have been many breakthroughs in birth control technologies, many of which have been beneficial for women. However, many feminists who advocate reproductive freedom also warn that freedom for some might lead to further oppression for others. The case in point is the practice of tubal ligation in the United States. Conflict theory indicates that the field of medicine is a social structure that is based upon capitalistic ideology and serves to perpetuate inequality. Feminist theory argues that medicine systematically disempowers women and that notions of family are very narrowly defined. This study examined the prevalence of tubal ligation among …

A Preclinical Model Of Ionizing Radiation And Tnf-Alpha Gene Therapy For Cancer, Jun Li

Loma Linda University Electronic Theses, Dissertations & Projects

Long term control of high-grade brain tumors is rarely achieved with current therapeutic regimens. This study sought to determine if pretreatment with plasmid DNA expressing Tumor Necrosis Factor-α (TNF-α) could enhance the effect of ionizing radiation in an aggressive, rapidly growing glioma tumor (C6) model. Plasmid DNA is an attractive vector system for delivery of foreign genes into eukaryotic cells due to its advantages including low immunogenicity in vivo, lesser toxicity and relatively low cost. We have constructed a plasmid-based mammalian expression vector (pGL1-TNF) to secrete human TNF-α from cancer cells. Plasmid DNA was successfully transfected into C6 cells …

Self-Reported Feeding Advice By Physicians For Common Childhood Illnesses, S Q. Nizami, Z A. Bhutta

Department of Paediatrics and Child Health

Background: A nutritious diet is important for recovery during illnesses. Dietary advice by physicians and consumption of food by the patients are often based upon their hot and cold concepts and beliefs about various foods rather than on scientific basis.
Objectives: To look at the food-advising behaviour of physicians during illnesses and to know the maternal concepts about various foods being hot or cold.
Methods: A questionnaire was served to the physicians participating in a continuous medical education session held at the Aga Khan University and Hospital, asking them to write the foods they advise or restrict during different illnesses …

Ethnic Variability In The Treatment Of Pain, Rafael A. Ortega, Benjamin A. Youdelman, Richard C. Havel

Department of Surgery Faculty Papers

Ethnicity has been shown to be an important determinant of behavior during illness, particularly when a painful condition is present. Studies have shown that pain may be undertreated among different ethnic groups of patients. Whereas individual variations in the reaction to pain occur, available data do not support racial and/or ethnic differences in the perception of pain, leaving no justification for this discrepancy in treatment. Regardless of ethnicity, inadequate treatment of pain has been known for some time and has been referred to in recent literature as "oligoanalgesia." Lack of understanding of different ethnic and cultural groups can lead to …

Immune Cd8+ T Cells Prevent Reactivation Of Toxoplasma Gondii Infection In The Immunocompromised Host, Imtiaz A. Khan, William R. Green, Lloyd H. Kasper, Kathy A. Green, Joseph D. Schwartzman

Dartmouth Scholarship

Toxoplasma gondii remains a serious cause of morbidity and mortality in individuals that are immunosuppressed, patients with AIDS in particular. The cellular immune response, especially by gamma interferon (IFN-γ)-producing CD8⁺ T cells, is an essential component of protective immunity against the parasite. In the present study the role of CD8⁺ T cells during the reactivation of Toxoplasma infection in an immunocompromised murine model was evaluated. Chronically infected mice were challenged with LP-BM5 virus, and the kinetics of CD8⁺ T-cell function was studied. At 10 weeks after viral infection, mice showed obvious signs of systemic illness and began …

Increased Matrix Synthesis Following Adenoviral Transfer Of A Transforming Growth Factor Beta1 Gene Into Articular Chondrocytes, Franklin D. Shuler Md, Phd, Helga I. Georgescu, Christopher Niyibizi, Rebecca K. Studer, Zhibao Mi, Brian Johnstone, Paul D. Robbins, Christopher H. Evans

Orthopaedics

Monolayer cultures of lapine articular chondrocytes were transduced with first-generation adenoviral vectors carrying lacZ or transforming growth factor β₁ genes under the transcriptional control of the human cytomegalovirus early promoter. High concentrations of transforming growth factor β₁ were produced by chondrocytes following transfer of the transforming growth factor β₁ gene but not the lacZ gene. Transduced chondrocytes responded to the elevated endogenous production of transforming growth factor β₁ by increasing their synthesis of proteoglycan, collagen, and noncollagenous proteins in a dose-dependent fashion. The increases in collagen synthesis were not accompanied by alterations in the collagen phenotype; …

Neurobehavioral And Neuromotor Long-Term Sequelae Of Prenatal Exposure To Cocaine And Other Drugs: An Unresolved Issue, Yvette Blanchard

All PTHMS Faculty Publications

When the cocaine epidemic began, predictions were made that the children of cocaine users would demonstrate devastating negative developmental sequelae. In infants and young children prenatally exposed to cocaine most frequently the neurobehavioral and neuromotor systems have been studied. Although clinically described as irritable, difficult to console, and jittery as infants, research findings have not been able to clearly describe a pattern of long-term developmental sequelae. The mechanisms of action of drug exposure on developmental outcome have shown to be more complex than originally suspected. Many factors, other than the drug use, can influence developmental outcome. In most studies of …

Immune Responses Induced By Gene Gun Or Intramuscular Injection Of Dna Vaccines That Express Immunogenic Regions Of The Serine Repeat Antigen From Plasmodium Falciparum, Alexia A. Belperron, David Feltquate, Barbara A. Fox, Toshihiro Horii, David J. Bzik

Dartmouth Scholarship

The liver- and blood-stage-expressed serine repeat antigen (SERA) of Plasmodium falciparum is a candidate protein for a human malaria vaccine. We compared the immune responses induced in mice immunized with SERA-expressing plasmid DNA vaccines delivered by intramuscular (i.m.) injection or delivered intradermally by Gene Gun immunization. Mice were immunized with a pcdna3 plasmid encoding the entire 47-kDa domain of SERA (amino acids 17 to 382) or the N-terminal domain (amino acids 17 to 110) of SERA. Minimal antibody responses were detected following DNA vaccination with the N-terminal domain of SERA, suggesting that the N-terminal domain alone is not highly immunogenic …

Differential Transcription Of The Tcpph Operon Confers Biotype-Specific Control Of The Vibrio Cholerae Toxr Virulence Regulon, Yvette M. Murley, Patricia A. Carroll, Karen Skorupski, Ronald K. Taylor, Stephen B. Calderwood

Dartmouth Scholarship

Epidemic strains of Vibrio cholerae O1 are divided into two biotypes, classical and El Tor. In both biotypes, regulation of virulence gene expression depends on a cascade in which ToxR activates expression of ToxT, and ToxT activates expression of cholera toxin and other virulence genes. In the classical biotype, maximal expression of this ToxR regulon in vitro occurs at 30 degrees C at pH 6.5 (ToxR-inducing conditions), whereas in the El Tor biotype, production of these virulence genes only occurs under very limited conditions and not in response to temperature and pH; this difference between biotypes is mediated at the …

P53 And Pcna Expression In Benign, Atypical And Malignant Meningiomas, R Ahmed, I N. Soomro, S A. Aziz, S H. Hasan

Department of Pathology and Laboratory Medicine

Objective: Alterations: p53 genes are turning out to be the most common genetic alterations in human cancers. Due to long half-life of mutated p53, its detection is possible by immunohistochemistry. Proliferating cell nuclear antigen (PCNA) is expressed by dividing cells, hence has been shown to correlate with prognosis. We have used monoclonal antibodies protein DO-7 (p53) and PC10 (PCNA) to see whether their expression correlates with histological grading in meningethelial tumour.
Material and Methods: a Twenty nine meningiomas (20 benign, 7 atypical and 2 malignant) were selected from the records of our laboratory. p53 and PCNA expression was sought by …
