Mechanisms Of Neuroprotection Against Ischemic Insult By Stress-Inducible Phosphoprotein-1, Jason Xu
Mechanisms Of Neuroprotection Against Ischemic Insult By Stress-Inducible Phosphoprotein-1, Jason Xu
Electronic Thesis and Dissertation Repository
Stress-inducible phosphoprotein-1 (STI1) levels are increased in the brain following ischemia. STI1 is a co-chaperone for Hsp70/Hsp90 modulating protein folding. STI1 can also be secreted by a number of cells and function to activate extracellular signalling by the prion protein (PrPC) and type-I bone morphogenetic protein receptor ALK2. However, the mechanisms by which STI1 can protect neurons against ischemia are currently unknown. A caspase-3 reporter mouse line was used to evaluate the consequences of increased extracellular STI1 levels. Neurons were treated with recombinant STI1 and specific agonists/antagonists for PrPC, α7nAChR, and ALK2 prior to oxygen-glucose deprivation …
Co-Morbidity Of Alzheimer’S Disease And Stroke: Cognitive Deficits And Cellular Pathologies In Two Co-Morbid Animal Models, Jennifer L. Au
Co-Morbidity Of Alzheimer’S Disease And Stroke: Cognitive Deficits And Cellular Pathologies In Two Co-Morbid Animal Models, Jennifer L. Au
Electronic Thesis and Dissertation Repository
Prior to beta-amyloid (Aβ) protein accumulation into plaques in Alzheimer’s disease (AD), neuroinflammation and oxidative stress have been shown to contribute to early cognitive decline. These cellular pathologies are coincident in stroke, which is considered a risk factor for AD. This study investigated the co-morbid effects of AD and stroke on behavioural and cellular pathology in two rodent models. Motor function, memory and microglial neuroinflammation were investigated in a stroke and Aβ injection model and mutant human amyloid precursor protein (APP) transgenic model with stroke. Injections of endothelin-1 into the right striatum were used to model stroke and AD was …
Oral Care Practice Guidelines For The Care-Dependent Hospitalized Adult Outside Of The Intensive Care Unit Setting, Cynthia Susan Drapal
Oral Care Practice Guidelines For The Care-Dependent Hospitalized Adult Outside Of The Intensive Care Unit Setting, Cynthia Susan Drapal
Walden Dissertations and Doctoral Studies
Many nurses lack evidence-based knowledge to deliver appropriate oral care, view oral care in the care-dependent patient as a comfort measure, and give it a low clinical priority. An estimated 44%-65% of hospitalized care-dependent patients do not receive adequate oral care, an intervention that can prevent aspiration pneumonia or pneumonitis. The purpose of this project was to develop a policy for use of an oral assessment tool and evidence-based guidelines for oral care in hospitalized care-dependent adults outside of the intensive care unit setting at a regional health system in the Southeast United States. The project used the theoretical foundations …
