Neuroinflammatory And Metabolomic Temporal Dynamics From Inhaled Wildfire Smoke With Attenuation Via Pharmacological Intervention, David Scieszka, David Scieszka

Biomedical Sciences ETDs

Wildfire smoke is a global issue affecting nearly all humans on the surface of this Earth. Smoke dispersion from wildfires can span continents and cross oceans with amazing ease. Furthermore, total acres of land burned per year in the United States has roughly doubled since 1980, meaning this issue will persist for an indeterminate amount of time. Exposure to wildfire smoke is hazardous and promotes aging-associated events in the cardiopulmonary systems. Yet long- and short-term effects on the brain remain relatively unknown. From these, it is critically important to understand the neurological impacts from wildfire smoke exposure; to compare these …

Translating Touches: New Approaches For Modeling And Rescuing Executive Function Deficits After Prenatal Alcohol Exposure, Johnny A. Kenton

Biomedical Sciences ETDs

Background: With a recent meta-analysis indicating that 9.8% of women worldwide consume alcohol during pregnancy, understanding the effects of fetal alcohol spectrum disorder (FASD) is critical for both identifying and treating those afflicted. Traditional preclinical research investigating the behavioral effects of neurodevelopmental disorders, such as FASD, has utilized tasks designed for specific animal models. For this reason, preclinical research into FASD requires a shift into clinically relevant behavioral testing. One such method involves touch-sensitive screens integrated into an operant box to emulate clinical computer-based tasks, such as the Cambridge Neuropsychological Test Automated Battery.

Methods: Here, we utilized a mouse model …

Cortico-Striatal Coordination Disrupted In Behaviorally Inflexible Moderate Prenatal Alcohol Exposed Mice, Kristin L. Marquardt

Biomedical Sciences ETDs

Up to 61% of adolescent school aged children with fetal alcohol spectrum disorder (FASD) have been suspended or expelled. Executive function deficits, like dis-inhibition and cognitive inflexibility, have been proposed to be better predictors of behavioral problems then IQ score, which qualifies these individuals for developmental disability and special school programs. Reversal learning, a widely used behavioral paradigm for assessing cognitive flexibility across species, has been shown to be impaired in rodent models of prenatal alcohol exposure (PAE). Here we show that a mouse model with daily maternal drinking, resulting in a BAC of 85 mg/dl throughout gestation, results in …
