Oxidative stress is a common hallmark of neuronal cell death associated with neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, as well as brain stroke/ischemia and traumatic brain injury. Increased accumulation of reactive species of both oxygen (ROS) and nitrogen (RNS) has been implicated inmitochondrial dysfunction, energy impairment, alterations in metal homeostasis and accumulation of aggregated proteins observed in neurodegenerative disorders, which lead to the activation/modulation of cell death mechanisms that include apoptotic, necrotic and autophagic pathways. Thus, the design of novel antioxidant strategies to selectively target oxidative stress and redox imbalance might represent important therapeutic approaches against neurological disorders. …

ESWL is an effective, non-invasive therapy utilized to fragment stones in the kidney and subsequently be cleared in the urinary tract. Although lithotripsy provides a safer alternative to invasive treatments for removing stones, ESWL may cause vasoconstriction after ESWL treatment, reducing renal blood flow, which can cause kidney damage leading to acute to chronic hypertension clinically. This may be due to kidney vascular endothelial dysfunction, which is characterized as increased oxidative stress and decreased endothelial nitric oxide synthase (eNOS)-derived nitric oxide (NO) bioavailability. We hypothesized that ESWL would decrease NO and increase hydrogen peroxide (H2O2) in …
Neuroprotective Effects Of Gamma-Glutamylcysteine Ethyl Ester On An In Vivo Moderate Traumatic Brain Injury-Mediated Model And In Vitro In Cortical Astrocytes And Neurons, Jooyoung Cho
Online Theses and Dissertations
Neurodegeneration is the loss of neuronal structures or functions, while neuroprotection is the delay or prevention of neurodegeneration. In traumatic brain injury (TBI), neurodegeneration can occur as the result of oxidative stress, the imbalance of oxidants and antioxidants levels; therefore, antioxidant approaches can be effective therapeutic methods for neuroprotection by attenuating oxidative stress. Glutathione (GSH), a naturally occurring antioxidant, plays an important role in the maintenance of intracellular redox homeostasis by scavenging reactive oxygen species (ROS) and reactive nitrogen species (RNS). In this thesis, we attempted to evaluate the abilities of a GSH precursor, gamma-glutamylcysteine ethyl ester (GCEE), to prevent …
