Nanoparticle Conjugated Photosensitizer For Targeted Photodynamic Inactivation Of Cancer Cells, Symone D. Crowder
Nanoparticle Conjugated Photosensitizer For Targeted Photodynamic Inactivation Of Cancer Cells, Symone D. Crowder
Honors College Theses
Photodynamic therapy (PDT) is considered to be a potential replacement for traditional methods of chemotherapy. It includes the administration of photosensitizing agents (PS), which generate reactive oxygen species (ROS) upon excitation at a specific wavelength. With new outlooks and techniques, cancer research is advancing each day. It has allowed the progress of several theranostic drug delivery systems (DDS) exploring the area of nanomedicine.2 In the present work, a Rhodamine derivative, Rhodamine 6G (R6G) was used as the PS. In general, rhodamine compounds undergo cytotoxic reactions on photoexcitation by electron transfer reactions with folic acid within cells, making them a favorable …
Unraveling Host-Gut Microbiota Dialogue And Its Impact On Response To Immune Checkpoint Blockade, Alexandria Cogdill
Unraveling Host-Gut Microbiota Dialogue And Its Impact On Response To Immune Checkpoint Blockade, Alexandria Cogdill
Dissertations & Theses (Open Access)
Cancer is a disease with only one degree of separation, affecting one in two men and one in three women in their lifetimes; accounting for 1 of every 6 deaths. While cancer mortality rates continue to improve, incidence rates are expected to rise and shift through 2050 due to epidemiological and demographic transitions worldwide. As such, it is imperative to continue to investigate and improve our understanding of both disease etiology and hallmarks of response to treatment. Currently, conventional therapies include, but are not limited to, surgery, chemotherapy, and radiotherapy. However, within the past decade, major advances have been made …
Synthesis Of New Aliphatic Pseudo-Branched Polyester Co-Polymers For Biomedical Applications, Zachary Shaw
Synthesis Of New Aliphatic Pseudo-Branched Polyester Co-Polymers For Biomedical Applications, Zachary Shaw
Electronic Theses & Dissertations
In this study, a hyperbranched polyester co-polymer was designed using a proprietary monomer and diethylene glycol or triethylene glycol as monomers. The synthesis was carried out using standard melt polymerization technique and catalyzed by p-Tolulenesulfonic acid. The progress of the reaction was monitored with respect to time and negative pressure, with samples being subjected to standard characterization protocols. The resulting polymers were purified using the solvent precipitation method and characterized using various chromatographic and spectroscopic methods including GPC, MALDI-TOF, and NMR. We have observed polymers with a molecular weight of 29,643 kDa and 33,996 kDa, which is ideal to be …
B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips
B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips
Seton Hall University Dissertations and Theses (ETDs)
Cancer-based immunotherapy has led the evolution of biologics that can stimulate immune responses towards tumor eradication. The synthesis of small to intermediate size molecules with the targeting and effector functions of mAb may represent a novel class of immunotherapeutics that may overcome the limitations of their biological counterparts.Towards this objective, B7H6 has been identified as a protein ligand localized on the cell surface of transformed tumor cells. B7H6 binds specifically to the activating receptor NKp30, constitutively expressed on all resting and active NK cells. Upon ligand:receptor binding, B7H6 triggers NK cell activation and release of chemokines and pro-inflammatory cytokines such …
Engineering Novel Detection And Treatment Strategies For Bacterial Therapy Of Cancer, Jan T. Panteli
Engineering Novel Detection And Treatment Strategies For Bacterial Therapy Of Cancer, Jan T. Panteli
Doctoral Dissertations
Finding and treating cancer is difficult due to limited sensitivity and specificity of current detection and treatment strategies. Many chemotherapeutic drugs are small molecules that are limited by diffusion, making it difficult to reach cancer sites requiring high doses that lead to systemic toxicity and off-target effects. Tomographic detection techniques, like PET, MRI and CT, are good at identifying macroscopic lesions in the body but are limited in their ability to detect microscopic lesions. Biomarker detection strategies are extremely sensitive and able to identify ng/ml concentrations of protein, but are poor at discriminating between healthy and disease state levels due …
