Glioblastoma is one of the most combative astrocytoma that is resistant to chemotherapy and radiotherapy. This resistance makes it very difficult to treat. However, researches have shown that nanoparticles especially C60 hydrofullerene have antioxidant and anticancer activity. The effect of C60 hydrofullerene in cancer has been extensively studied; however, the potential regulation of autophagy and modulation of the Glial Fibrillary Acidic Protein (GFAP) gene has not been addressed in glioblastomas. Glioblastoma U-373 cell was treated with 0.5 µM of C60 hydrofullerene and/or 1 mM of hydrogen peroxide (H2O2) for 24 hours. This study demonstrated that C60 hydrofullerene and H2O2 significantly …
Effects Of Localized Oxygen Production By Electrolysis On The First-Generation Glucose Sensor Response, Nandita Halder
Effects Of Localized Oxygen Production By Electrolysis On The First-Generation Glucose Sensor Response, Nandita Halder
Graduate Theses and Dissertations
Glucose sensors are very important for detecting blood glucose both in vitro and in vivo. First-generation glucose biosensors were based on the glucose oxidase (GOx) enzyme using molecular oxygen as the electron acceptor and therefore oxygen dependent. Unfortunately for in-vivo work, oxygen in the body is variable and limited. Alternative approaches to overcome the oxygen dependency came with their own limitations. The widely used and commercially available ex-vivo glucose test strip uses a mediator in place of oxygen to free it from oxygen dependency. The mediator-based technology, in most cases cannot be transferred to in vivo applications due to the …
Hydrogen Peroxide Inhibition And Inactivation Of Bicupin Oxalate Oxidase, John M. Goodwin Vii
Hydrogen Peroxide Inhibition And Inactivation Of Bicupin Oxalate Oxidase, John M. Goodwin Vii
Master of Science in Chemical Sciences Theses
Oxalate oxidase is a manganese containing enzyme that catalyzes the oxygen dependent oxidation of oxalate to carbon dioxide and hydrogen peroxide. Oxalate oxidase from Ceriporiopsis subvermispora (CsOxOx) is the first characterized bicupin oxalate oxidase. Potential applications of oxalate oxidase in cancer treatment, paper pulping, and biofuel cells highlight the need to study the effects of hydrogen peroxide on the CsOxOx catalyzed oxidation of oxalate. Membrane inlet mass spectrometry (MIMS) was used to directly measure initial rates of carbon dioxide formation and oxygen consumption in varying initial concentrations of hydrogen peroxide. This work demonstrates that hydrogen peroxide is both a reversible …
