Cellular And Molecular Mechanism Underlying Alcohol Inhibition Of Bone Fracture Healing, Jonathan Michael Eby
Dissertations
Alcohol consumption is associated with increased risk taking and injuries leading to bone fracture. During bone fracture repair mesenchymal stem cells (MSCs) located at the site of injury differentiate into chondrocytes and osteoblasts to form a fracture callus. While most fractures heal without complication, studies show that alcohol abuse can lead to delayed fracture healing and fracture callus formation in both people and animals. Despite what is known about alcohol consumption in pre-injury pathologies like osteopenia and osteoporosis, the cellular and molecular mechanisms by which alcohol consumption inhibits fracture callus formation following orthopaedic injury remain to be elucidated. Here, we …

Inflammatory bowel diseases (IBD) affect a large number of individuals around the world. This group of diseases is largely composed of two types: Crohn's disease (CD) and ulcerative colitis (UC). Upon development of IBD, patients experience cyclical episodes of inflammation, known as flares. Flare induction appears to arise from multiple factors, which can also vary on a person-to-person basis. Alcohol has been shown to trigger IBD flares and onset, though the underlying mechanism has not been established.Defining factors of the IBD intestinal environment include an altered microbiome, bacterial infiltration of the intestinal epithelium, and increased leakage of proinflammatory bacterial byproducts. …
