The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski

Biomedical Sciences ETDs

Mild traumatic brain injuries (mTBIs) often lead to acute symptoms like disorientation and discoordination, but the underlying mechanisms are unknown. Although most patients recover quickly from a single mTBI, repeated injuries can be debilitating. After an mTBI, a neurometabolic cascade produces metabolic burden and vulnerability. Spreading depolarizations (SDs) have been observed after mTBIs. Here we investigated SDs’ role in short-term motor behavioral deficits post-mTBI. We hypothesized that SDs contribute to the deficits, and exacerbated symptoms after repeated mTBIs. To test this, we used acute motor behavioral tests and long-term behavioral and cognitive tests after initiating SDs by mTBI, chemical, or …

Effects Of Acute And Chronic Gut Injury On Secretory Lineage Differentiation, Roger Atanga

Biomedical Sciences ETDs

Acute and chronic injury to the gut has several detrimental consequences. However, dysregulation of secretory lineage cells is a common observation. To model acute gut injury, we use non-fissile uranium bearing dust (UBD), an environmental toxicant prevalent in communities adjacent abandoned uranium mines, majority of which are located in the Southwestern United States. Repeated exposure to environmental toxins and heavy metals has been obscurely linked to intestinal inflammation, increased susceptibility to pathogen-induced diseases, and higher incidences of colorectal cancer. However, there is no molecular evidence that non-fissile uranium can cause damage to the intestinal epithelia. Human colonoids exposed to UBD …
