All Works

Atopic dermatitis (AD) is a multifactorial skin disorder characterized by immune dysregulation, impaired epidermal barrier, and strong microbial imbalance. Although genetic susceptibility and environmental triggers are established AD drivers, growing evidence highlights the gut skin axis as an important but underexplored AD pathogenesis factor. Gut microbiota dysbiosis, loss of short-chain fatty acid (SCFA)-producing bacteria, and altered metabolite profiles, such as tryptophan derivatives and secondary bile acids, have been linked to systemic immune imbalance and skin inflammation. However, the precise mechanism by which gut microbial alterations influence cutaneous immunity remains unclear. This review synthesizes recent advances from clinical and experimental studies …

The Highlander Folk School: Incubator For Grassroots Democracy And Its Impacts On The Southern Civil Rights Movement, Kathleen Mcmichael Goodyear

Electronic Theses & Dissertations

Despite the Highlander Folk School’s having played multiple vital roles in the Southern civil rights movement of the 1950s and 1960s, the general public remains unaware of Highlander, which is largely due to its having been omitted from most U.S. history survey course textbooks and ignored by most mainstream historians. These sources perpetuate the image propagated by the 1960s media that the movement was largely composed of Rev. Dr. Martin Luther King, Jr. and his fellow charismatic Black male ministers leading their flock of followers—but the movement was much more than that. Highlander’s rich history in nurturing Southern grassroots activism …
