Differential Expression Of Chemokines In A Mouse Model Of Wound Healing, Susan H. Jackman, Matthew B. Yoak, Shivaleela Keerthy, Bonnie L. Beaver

Biochemistry and Microbiology

Macrophages have a multifaceted role in wound healing. While their initial activity may be in the degradation and elimination of damaged tissue, macrophages also produce and secrete a variety of mediators that can participate in the repair process as well. To perform these functions, macrophages must be recruited to a wound site. Our purpose was to examine the temporal and spatial expression of macrophage chemoattracting cytokines (chemokines) at a surgical wound site. A surgical wound was prepared on the dorsal aspect of B6AFI/J mice. Biopsies were obtained from the wound and a comparable nonwounded area between 6 and 72 hr …

Dietary Fish Oil Sensitizes A549 Lung Xenografts To Doxorubicin Chemotherapy, W. Elaine Hardman, Mary Pat Moyer, Ivan L. Cameron

Biochemistry and Microbiology

A549 xenografts were allowed to grow in nude mice to about 5 mm in diameter, then diets were changed to modified AIN-76 diets containing 19% wt/wt. fish oil (FO) or 20% wt./wt. com oil (CO). Ten days later dietary ferric citrate (0.3% wt./dry wt.) was added and doxoribicin (DOX) treatment (3.6 mg/kg i.v. each of the 5 days for 18 days) commenced. Treatment with DOX halted the growth of tumors in the CO fed mice. However, in those mice, which consumed FO or FO with ferric citrate, treatment with DOX caused significant tumor regression.

Characterization Of Human T-Cell Leukemia Virus 1 Reverse Transcriptase, Pinky Gundayao Agbuya

Theses and Dissertations in Biomedical Sciences

Human T-cell leukemia virus 1 (HTLV-1) is a type C human retrovirus which has been the causative agent of Adult T-cell leukemia. Replication of the retrovirus; requires a reverse transcriptase which converts the retroviral RNA into DNA which is later incorporated into the host's genome. Very little is known about the reverse transcriptase of HTLV-1. Researchers have attempted to purify HTLV-1 RT by isolating the enzyme from human cell lines. Because large amounts of protein could not be produced by this isolation method, the reverse transcriptase cannot be fully characterized. In this research, a recombinant protein expressed in E. coli …

Ubinuclein, A Novel Nuclear Protein Interacting With Cellular And Viral Transcription Factors., S Aho, M Buisson, T Pajunen, Y W Ryoo, J F Giot, H Gruffat, A Sergeant, Jouni Uitto

Department of Dermatology and Cutaneous Biology Faculty Papers

The major target tissues for Epstein-Barr virus (EBV) infection are B lymphocytes and epithelial cells of the oropharyngeal zone. The product of the EBV BZLF1 early gene, EB1, a member of the basic leucine-zipper family of transcription factors, interacts with both viral and cellular promoters and transcription factors, modulating the reactivation of latent EBV infection. Here, we characterize a novel cellular protein interacting with the basic domains of EB1 and c-Jun, and competing of their binding to the AP1 consensus site. The transcript is present in a wide variety of human adult, fetal, and tumor tissues, and the protein is …

The Pl(A2) Polymorphism Of Integrin Beta(3) Enhances Outside-In Signaling And Adhesive Functions., K Vinod Vijayan, Pascal J. Goldschmidt-Clermont, Christine Roos, Paul F. Bray

Cardeza Foundation for Hematologic Research

Genetic factors are believed to influence the development of arterial thromboses. Because integrin alpha(IIb)beta(3) plays a crucial role in thrombus formation, we analyzed receptor adhesive properties using Chinese hamster ovary and human kidney embryonal 293 cells overexpressing the Pl(A1) or Pl(A2) polymorphic forms of alpha(IIb)beta(3). Soluble fibrinogen binding was no different between Pl(A1) and Pl(A2) cells, either in a resting state or when alpha(IIb)beta(3) was activated with anti-LIBS6. Pl(A1) and Pl(A2) cells bound equivalently to immobilized fibronectin. In contrast, significantly more Pl(A2) cells bound to immobilized fibrinogen in an alpha(IIb)beta(3)-dependent manner than did Pl(A1) cells. Disruption of the actin cytoskeleton …

Impact Of Bovine Oocyte Maturation Media On Oocyte Transcript Levels, Blastocyst Development, Cell Number, And Apoptosis., A J Watson, P De Sousa, A Caveney, L C Barcroft, D Natale, J Urquhart, M E Westhusin

Obstetrics & Gynaecology Publications

The objectives were 1) to investigate the effects of oocyte maturation in serum-free and amino acid-supplemented defined media on oocyte transcript levels, blastocyst cell number, and apoptosis; 2) to investigate the influence of oocyte maturation culture atmosphere on blastocyst development, total cell number, and apoptosis; and 3) to examine the influence of epidermal growth factor (EGF) during oocyte maturation on blastocyst cell number and apoptosis. The results demonstrate that blastocysts derived from in vitro maturation, fertilization, and embryo culture protocols undergo apoptosis but that apoptotic levels are not greatly influenced by the oocyte maturation environment. Amino acid supplementation of oocyte …

Intimate Partner Violence And Cervical Neoplasia, Ann L. Coker, Maureen Sanderson, Mary Kay Fadden, Lucia Pirisi

CRVAW Faculty Journal Articles

Intimate partner violence (IPV) is associated with a range of adverse physical health outcomes, including chronic and infectious diseases. An emerging literature suggests that partner violence and specifically sexual violence may be associated with an increased risk of cervical neoplasia. To assess the risk of preinvasive and invasive cervical cancer in a cross-sectional study of women screened for IPV by type, frequency and duration, 1152 women ages 18–65 were recruited from family practice clinics in 1997–1998. They were screened for IPV during a brief in-clinic interview, and health history and current status were assessed in a follow-up interview. Of 1152 …

Role Of KAtp Channels In Reduced Antinociceptive Effect Of Morphine In Streptozotocin-Induced Diabetic Mice, Vivek Sood, Ajay Sharma, Manjeet Singh

Pharmacy Faculty Articles and Research

The nociceptive effect was measured using withdrawal latency in tail flick test in mice rendered diabetic by administering streptozotocin (200 mg/kg, i.p.). The antinociceptive effect of morphine (4 and 8 mg/kg, s.c.) and cromakalim, a KATP channel opener, (0.3, 1 and 2 micrograms, i.c.v.) was significantly reduced in diabetic mice. Moreover, co-administration of cromakalim(0.3 microgram) did not alter the reduced antinociceptive effect of morphine(4 mg/kg) in diabetic mice. Spleenectomy in diabetic mice restored the decrease in antinociceptive effect of morphine and cromakalim. Multiple dose treatment with insulin to maintain euglycaemia for 3 days in diabetic mice prevented the decrease in …

Identification Of The Transactivation Domain Of The Transcription Factor Sox-2 And An Associated Co-Activator, Tamara K. Nowling, Lance R. Johnson, Matthew S. Wiebe, Angie Rizzino

Nebraska Center for Virology: Faculty Publications

The importance of interactions between Sox and POU transcription factors in the regulation of gene expression is becoming increasingly apparent. Recently, many examples of the involvement of Sox-POU partnerships in transcription have been discovered, including a partnership between Sox-2 and Oct-3. Little is known about the mechanisms by which these factors modulate transcription. To better understand the molecular interactions involved, we mapped the location of the transactivation do-main of Sox-2. This was done in the context of its interaction with Oct-3, as well as its ability to transactivate as a fusion protein linked to the DNA-binding domain of Gal4. Both …

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 …

Ethical Issues In Dementia, Peter J. Whitehouse

Faculty Scholarship

The growing number of individuals affected by dementia will intensify the ethical issues that emerge in clinical practice and research, issues early in disease relate to genetic testing, use of medications in mildly affected persons, and diagnostic disclosure. Research issues relate to appropriate informed consent processes, conflict of interests, and research design issues, such as the use of placebos and the use of biological tissues. In the later stages of disease concern about appropriate therapeutic goals and end-of-life care is appropriate.

Micronutrient And Iron Supplementation And Effective Anti-Malarial Treatment Synergistically Improve Childhood Anaemia, H. Ekvall, Zul Premji, A. Bjorkman

Pathology, East Africa

The control of childhood anaemia in malaria holoendemic areas is a major public health challenge for which an optimal strategy remains to be determined. Malaria prevention may compromise the development of partial immunity. Regular micronutrient supplementation has been suggested as an alternative but its effectiveness remains unsettled. We therefore conducted a randomised placebo-controlled intervention trial with 207 Tanzanian children aged 5 months to 3 years on the efficacy of supervised supplementation of low-dose micronutrients including iron (Poly Vi-Sol with iron) three times per week, with an average attendance of ≥ 90%. The mean haemoglobin (Hb) level increased by 8 g/l …

Assessment Of Prothrombotic Tendency In Humans Using Functional And Genomic Determinants, Pádraig O'Sullivan

Theses

Thrombophilia describes the familial or acquired disorders of the haemostatic mechanism that are likely to predispose to thrombosis. Venous thrombosis and its associated complications account for a significant number of hospital admissions and deaths annually having a significant health-economic impact on the heath-care industry globally. Mutations in genes that code for proteins involved directly (or indirectly) in blood coagulation have been associated with prothrombotic states. The majority of inherited genetic defects were attributed to polymorphisms in Antithrombin III, Protein C, and Protein S genes until 1994. Together these accounted for only 5-10% of individuals with thrombosis. Subsequently the Factor V …

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 …

Attitudes, Practices And Knowledge Regarding Cervical Cancer Screening Among Greek Women In The Area Of Perth, Panagiota Karnaki

Theses: Doctorates and Masters

The purpose of this thesis is to study the attitudes, practices and knowledge of Greek women in Perth, Western Australia, regarding cervical cancer screening. This is important because no study has yet examined the cervical screening pattern of this group, despite their low participation rate in screening programs. Qualitative semi-structured interviews among 15 Greek women in Perth were used for data collection. Interviews were conducted both in English and Greek. Eight out of the 15 women interviewed did not participate in frequent screening and many had had only one Pap test in their life. Culture and religion influenced negative attitudes …

The Use Of The Cognitive Status Examination In Detecting Cognitive Impairment In Elderly People, Geoff Mccann

Theses: Doctorates and Masters

Dementia is a growing social problem in Australia because as the population ages, the incidence of dementia increases. While the prevalence rates are only about I% at age 65, they double every five years until by 85 years of age the rate is over 24%. It is expected that by the year 2030, the number of elderly people with dementia will increase by 200%. Dementia is easily recognized in its advanced stages but can be overlooked in the early phase. Family members, care-givers and even the treating medical practitioner may mistakenly attribute the early decline in mental function to the …

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 …
