Pharmaceutical Sciences Faculty Publications
Background: The use of neo-adjuvant chemotherapy in treating osteosarcoma has improved patients’ average 5 year survival rate from 20% to 70% in the past 30 years. However, for patients who progress after chemotherapy, its effectiveness diminishes due to the emergence of multi-drug resistance (MDR) after prolonged therapy.
Methodology/Principal Findings: In order to overcome both the dose-limiting side effects of conventional chemotherapeutic agents and the therapeutic failure resulting from MDR, we designed and evaluated a novel drug delivery system for MDR1 siRNA delivery. Novel biocompatible, lipid-modified dextran-based polymeric nanoparticles were used as the platform for MDR1 siRNA delivery; and the ...

Evaluating The Impact Of The Guatemalan Nursing Program On Staff, Organizational, And Clinical Outcomes, 2010 University of Tennessee Health Science Center
Evaluating The Impact Of The Guatemalan Nursing Program On Staff, Organizational, And Clinical Outcomes, Sara Williamson Day
Theses and Dissertations (ETD)
There is great disparity between the outcome of childhood cancer in developed and developing countries. Nurses, who comprise the largest group of health care professionals globally, are essential to successful treatment. Pediatric oncology education is generally unavailable for nurses in developing countries. This lack of education is likely to contribute to the disparity in survival rates, as undereducated nurses are unable to meet the demands of pediatric cancer care. A second critical problem in developing countries is the workload of the nurse, with a patient nurse ratio reported as high as 30 patients per one nurse.
In 2006, the quality ...

Prostate cancer is the second leading cause of cancer-related death and the most common non-skin cancer in men in the USA. Considerable advancements in the practice of medicine have allowed a significant improvement in the diagnosis and treatment of this disease and, in recent years, both incidence and mortality rates have been slightly declining. However, it is still estimated that 1 man in 6 will be diagnosed with prostate cancer during his lifetime, and 1 man in 35 will die of the disease.
In order to identify novel strategies and effective therapeutic approaches in the fight against prostate cancer, it ...
Thoracic Radiotherapy Treatment Planning With Cine Pet/Ct, 2010 University of Texas Graduate School of Biomedical Sciences at Houston
Thoracic Radiotherapy Treatment Planning With Cine Pet/Ct, Adam C. Riegel
UT GSBS Dissertations and Theses (Open Access)
Purpose: Respiratory motion causes substantial uncertainty in radiotherapy treatment planning. Four-dimensional computed tomography (4D-CT) is a useful tool to image tumor motion during normal respiration. Treatment margins can be reduced by targeting the motion path of the tumor. The expense and complexity of 4D-CT, however, may be cost-prohibitive at some facilities. We developed an image processing technique to produce images from cine CT that contain significant motion information without 4D-CT. The purpose of this work was to compare cine CT and 4D-CT for the purposes of target delineation and dose calculation, and to explore the role of PET in target ...
Il-2 Regulation Of Il-24 Expression Leads To Growth Suppression Of Melanoma Cells, 2010 University of Texas Graduate School of Biomedical Sciences at Houston
Il-2 Regulation Of Il-24 Expression Leads To Growth Suppression Of Melanoma Cells, Emily Jen
UT GSBS Dissertations and Theses (Open Access)
Melanoma is known to be highly resistant to chemotherapy. Treatment with high dose IL-2 has shown significant clinical benefit in a minority of metastatic melanoma patients and has lead to long term survival in a few cases. However, this treatment is associated with excessive multiorgan toxicities, which severely limits its use. We hypothesize that one mechanism of effective IL-2 therapy is through the direct upregulation of IL-24 production in melanoma tumors and subsequent IL-24 mediated tumor growth suppression.
Five melanoma cell lines were treated with high dose recombinant hIL-2 at 1000U/ml. Three of the cell lines (A375, WM1341, WM793 ...
Oral Cancer In Nevada: A Public Health Perspective, 2010 University of Nevada Las Vegas
Oral Cancer In Nevada: A Public Health Perspective, Karl Kingsley
UNLV Theses, Dissertations, Professional Papers, and Capstones
Cancer is the second leading cause of death in the United States, and oral cancer remains the eighth leading cause of cancer death among US males. Although previous epidemiologic studies have found that overall rates of cancer, including oral cancer, have declined in the US in recent decades – these declines are neither uniform nor consistent within this population. Anecdotal evidence has suggested that rates of oral cancer in Nevada are relatively high, although no evidence was available to support these assertions.
Oral Cancer Epidemiology: Based upon this information, a detailed and thorough epidemiologic examination of oral cancer rates in Nevada ...
Pathogenic Interactions Between Alcohol And Hepatitis C, 2010 University of Massachusetts Medical School
Pathogenic Interactions Between Alcohol And Hepatitis C, Gyongyi Szabo
Alcohol is the most commonly abused substance in the United States, and alcohol abuse leads to alcoholic liver disease, a long recognized major public health concern. The high prevalence of chronic hepatitis C virus (HCV) infection, along with the clinical observation that HCV infection is common in alcoholic patients presenting with liver disease, has directed attention to the interaction between alcohol and HCV infection. Clinical studies have identified alcohol use as an independent risk factor for progression of fibrosis in chronic HCV infection. Experimental evidence suggests additive inhibitory effects between HCV and alcohol on antiviral immune responses. In addition, specific ...

Rituximab is an important and well established component in the treatment of many patients with B-cell non-Hodgkin lymphoma. In this paper we review recent clinical trials investigating the addition of rituximab to standard chemotherapy regimens for treatment of patients with diffuse large B cell lymphoma and follicular lymphoma. This report focuses upon treatment efficacy, quality of life, and safety of rituximab or rituximab-containing regimens. More uniquely, we review economic aspects of lymphoma treatments, including the cost of standard chemotherapy regimens with or without rituximab, cost effectiveness of rituximab in both induction and maintenance treatment, and lymphoma's impacts on patient ...

Thirty-three age eligible residents completed the CRC screening questionnaires and received education on CRC screening. Twenty-nine of the age-eligible participants were found to be at average risk and twenty-three elected to receive FOBT testing ...
Capsaicin Displays Anti-Proliferative Activity Against Human Small Cell Lung Cancer In Cell Culture And Nude Mice Models Via The E2f Pathway, Kathleen C. Brown, Theodore R. Witte, W. Elaine Hardman, Haitao Luo, Yi C. Chen, A. Betts Carpenter, Jamie K. Lau, Piyali Dasgupta
Biochemistry and Microbiology
Background: Small cell lung cancer (SCLC) is characterized by rapid progression and low survival rates. Therefore, novel therapeutic agents are urgently needed for this disease. Capsaicin, the active ingredient of chilli peppers, displays antiproliferative activity in prostate and epidermoid cancer in vitro. However, the anti-proliferative activity of capsaicin has not been studied in human SCLCs. The present manuscript fills this void of knowledge and explores the anti-proliferative effect of capsaicin in SCLC in vitro and in vivo.
Methodology/Principal Findings: BrdU assays and PCNA ELISAs showed that capsaicin displays robust anti-proliferative activity in four human SCLC cell lines. Furthermore, capsaicin ...

The role of bilevel positive airway pressure (BIPAP) and Vapotherm in the relief of dyspnea have not been well defined. We aimed to determine and to compare the efficacy of BIPAP and VapoTherm for cancer related dyspnea.
Methods: In this randomized, open-label, crossover study, we randomly assigned advanced cancer patients with persistent dyspnea >=3/10 to either Vapotherm for 2 hours followed by BiPAP for 2 hours, or BiPAP followed by Vaptherm. A variable washout period was instituted between interventions. The primary end point was change in ...
Trastuzumab Sensitizes Ovarian Cancer Cells To Egfr-Targeted Therapeutics, 2010 Yale University
Trastuzumab Sensitizes Ovarian Cancer Cells To Egfr-Targeted Therapeutics, Jason A. Wilken, Kristy T. Webster, Nita J. Maihle
Open Access Articles
BACKGROUND: Early studies have demonstrated comparable levels of HER2/ErbB2 expression in both breast and ovarian cancer. Trastuzumab (Herceptin), a therapeutic monoclonal antibody directed against HER2, is FDA-approved for the treatment of both early and late stage breast cancer. However, clinical studies of trastuzumab in epithelial ovarian cancer (EOC) patients have not met the same level of success. Surprisingly, however, no reports have examined either the basis for primary trastuzumab resistance in ovarian cancer or potential ways of salvaging trastuzumab as a potential ovarian cancer therapeutic.
METHODS: An in vitro model of primary trastuzumab-resistant ovarian cancer was created by long-term ...
Rbc And Wbc Fatty Acid Composition Following Consumption Of An Omega 3 Supplement: Lessons For Future Clinical Trials, Theodore R. Witte, Alexander J. Salazar, Oscar F. Ballester, W. Elaine Hardman
Biochemistry and Microbiology
Background: Results from increasing numbers of in vitro and in vivo studies have demonstrated that omega 3 fatty acids incorporated in cell culture media or in the diet of the animals can suppress the growth of cancers. When human clinical trials are initiated to determine the ability of omega 3 fatty acids to alter growth or response to chemotherapeutic interventions of cancers, it will be essential to determine the omega 3 intake of individuals in the trial to determine compliance with consumption of the supplement and to correlate with endpoints of efficacy. We wondered if the fatty acid composition of ...

Siti Zawiah Omar
Objective: To determine if shoulder dystocia can be predicted in babies born weighing 3.5 kg or more. Study design: A case-control study nested in a perinatal database of 899 mothers and their babies who weighed 3.5 kg or more. All were term pregnancies and delivered vaginally. A case was defined as any baby that encountered shoulder dystocia at delivery. Controls were deliveries over the same period that were not complicated by shoulder dystocia. A logistic regression model was created with macrosomia, parity, previous delivery of more than 3.5 kg, diabetes in pregnancy, prolonged labor, prolonged second stage ...
X Chromosome-Wide Analyses Of Genomic Dna Methylation States And Gene Expression In Male And Female Neutrophils, 2010 Yale University School of Medicine
X Chromosome-Wide Analyses Of Genomic Dna Methylation States And Gene Expression In Male And Female Neutrophils, Yukio Yasukochi, Osamu Maruyama, Milind C. Mahajan, Carolyn Padden, Ghia M. Euskirchen, Vincent Schulz, Hideki Hirakawa, Satoru Kuhara, Xing-Hua Pan, Peter E. Newburger, Michael Snyder, Sherman M. Weissman
The DNA methylation status of human X chromosomes from male and female neutrophils was identified by high-throughput sequencing of HpaII and MspI digested fragments. In the intergenic and intragenic regions on the X chromosome, the sites outside CpG islands were heavily hypermethylated to the same degree in both genders. Nearly half of X chromosome promoters were either hypomethylated or hypermethylated in both females and males. Nearly one third of X chromosome promoters were a mixture of hypomethylated and heterogeneously methylated sites in females and were hypomethylated in males. Thus, a large fraction of genes that are silenced on the inactive ...
