Brain Injury And Inflammation And Placental Inflammation In Response To Repetitive Umbilical Cord Occlusions In The Near Term Ovine Fetus, Alex Xu
Electronic Thesis and Dissertation Repository
We hypothesized that repetitive umbilical cord occlusions (UCOs) leading to severe acidemia will stimulate a placental and fetal inflammatory response associated with brain injury, which will be exacerbated by chronic hypoxemia and low-grade infection. Chronically instrumented fetal sheep served as controls or underwent repetitive UCOs for up to 4 hours or until fetal arterial pH was2saturation pre-UCOs of >55% and

Differential Activation Of Microglia In An In Vitro Model Of Intracerebral Hemorrhage, Bhakti Patel
Honors Capstone Projects - All
An in vitro model of intracerebral hemorrhage was established to examine the protective versus cytotoxic roles of microglia in the context of mild versus severe injury. Co-cultures of microglia, astrocytes, and granule neurons were prepared from the cerebellar cortex of neonatal rats, and grown in standard medium containing fetal bovine serum or, in some cases, a serum-free chemically defined medium. To mimic hemorrhagic stroke, co-cultures grown for 7-8 days in vitro were challenged with two different concentrations of the toxic blood product hemin, corresponding to a mild versus a severe brain bleed. Immunocyto-chemical, real-time RT-PCR, iron deposition, and cell survival …

Mechanisms Of Neural Precursor Cell Apoptosis By Microglia-Derived Cytokines, Jennifer Guadagno
Electronic Thesis and Dissertation Repository
The persistence of neural precursor cells (NPCs) in distinct niches of the adult brain and spinal cord provides an important opportunity for regeneration in the affected nervous system. In the adult brain, neural precursor cells (NPCs) generate new neurons that can be integrated into the CNS circuitry to replace damaged or lost neurons, and contribute to learning and memory processes. Deregulated neurogenesis has been observed under both acute and chronic neurological conditions including stroke, Alzheimer’s disease, and Parkinson’s disease. The extent to which neurogenesis contributes to brain repair is severely limited by the neuroinflammatory processes associated with these neurodegenerative conditions. …
