Cultured neurons tolerate low H(2)O(2) concentrations (< or =50 microM) through the activity of constitutive antioxidant response elements (ARE). At H(2)O(2) levels (> or =100 microM), neurons increase expression of the gene encoding for inducible hemoxygenase-1 while superoxide dismutase-2 and catalase remain unchanged. Despite this adaptive response, the(More)
In Alzheimer's disease (AD), rod-like cofilin aggregates (cofilin-actin rods) and thread-like inclusions containing phosphorylated microtubule-associated protein (pMAP) tau form in the brain (neuropil threads), and the extent of their presence correlates with cognitive decline and disease progression. The assembly mechanism of these respective pathological(More)
Oxidative stress is associated with the pathology of acute and chronic neurodegenerative disease. We have cloned a human neuroglobin (Nb) construct and over-expressed this protein in cultured human neuronal cells to assess whether Nb ameliorates the cellular response to experimental hypoxia-reoxygenation (H/R) injury. Parental cells transfected with a blank(More)
Oxidative stress is associated with the pathology of acute and chronic neurodegenerative disease. Cultured human neuronal cells exposed to experimental hypoxia-re-oxygenation (H/R) injury responded with an increased production of reactive oxygen species (ROS) and a significant decrease in intracellular ATP. Expression of genes encoding for hypoxia-inducible(More)
Since its discovery in 2000, neuroglobin (Nb) has been demonstrated to have an essential and conserved function in vertebrates with the consequential discovery of a neuroprotective role. Nb is a member of the globin superfamily and is predominantly expressed in neurons of the central and peripheral nervous system. Thorough studies have been performed to(More)
OBJECTIVE To explore common barriers medical students perceive to choosing psychiatry as a medical specialty as reflected in existing literature and the authors' own experiences and whether funding student attendance of a Royal Australian and New Zealand College of Psychiatrists Congress serves to overcome some of these perceptions. CONCLUSIONS Common(More)
