Background: Drug resistance is a primary hindrance for the efficiency of chemotherapy against osteosarcoma. Although chemotherapy has improved the prognosis of osteosarcoma patients dramatically after introduction of neo-adjuvant therapy in the early 1980's, the outcome has since reached plateau at approximately 70% for 5 year survival. The remaining 30% of the patients eventually develop resistance to multiple types of chemotherapy. In order to overcome both the dose-limiting side effects of conventional chemotherapeutic agents and the therapeutic failure incurred from multidrug resistant (MDR) tumor cells, we explored the possibility of loading doxorubicin onto biocompatible, lipid-modified dextran-based polymeric nanoparticles and evaluated the …

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 efficacy …
Macrophages Loaded With Gold Nanoshells For Photothermal Ablation Of Glioma: An In Vitro Model, Amani Riad Makkouk
Macrophages Loaded With Gold Nanoshells For Photothermal Ablation Of Glioma: An In Vitro Model, Amani Riad Makkouk
UNLV Theses, Dissertations, Professional Papers, and Capstones
The current median survival of patients with glioblastoma multiforme (GBM), the most common type of glioma, remains at 14.6 months despite multimodal treatments (surgery, radiotherapy and chemotherapy). This research aims to study the feasibility of photothermal ablation of glioma using gold nanoshells that are heated upon laser irradiation at their resonance wavelength. The novelty of our approach lies in improving nanoshell tumor delivery by loading them in macrophages, which are known to be recruited to gliomas via tumor-released chemoattractive agents. Ferumoxides, superparamagnetic iron oxide (SPIO) nanoparticles, are needed as an additional macrophage load in order to visualize macrophage accumulation in …
The Power Of Empowerment: An Icf-Based Model To Improve Self-Efficacy And Upper Extremity Function Of Survivors Of Breast Cancer, Mary Insana Fisher, Dana Howell
The Power Of Empowerment: An Icf-Based Model To Improve Self-Efficacy And Upper Extremity Function Of Survivors Of Breast Cancer, Mary Insana Fisher, Dana Howell
Physical Therapy Faculty Publications
Breast cancer is one of the most frequently diagnosed cancers among women. Breast cancer treatments often negatively impact the function of the arm, and quality of life and upper extremity function does not always return to a prediagnosis level. Survivors of breast cancer may also experience feelings of diminished self-efficacy related to functional deficits resulting from their physical limitations. The International Classification of Functioning (ICF) provides a framework for rehabilitation practitioners to address physical and psychological impairments, activity limitations, and participation restrictions. Patient outcomes may be improved by fostering self-efficacy through empowerment. This paper explores how the ICF model and …
Quantification Of Circulating Melanoma Cells, Jamie Freeman
Quantification Of Circulating Melanoma Cells, Jamie Freeman
Theses : Honours
Current prognostic techniques for Cutaneous Malignant Melanoma (CMM), a highly aggressive and drug resistant skin cancer, are inadequate at managing the disease and identifying early stage patients requiring treatment. It is thought that Circulating Tumour Cells (CTCs), which circulate in patient blood after being shed from solid tumours, may be useful in enhancing prognostic techniques and it has previously been shown in other malignancies that the presence of CTCs in patient blood is associated with poor prognosis. In CMM, CTCs can be detected through RT-PCR for melanoma associated markers, although this technique does not allow CTCs to be quantified. In …
