Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disturbances that includes simple steatosis, non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and liver cancer. NAFLD affects individuals that consume the typical Western diet consisting of high levels of fats and carbohydrates. The increase in circulating free fatty acids, palmitate and oleate, or lipopolysaccharides (LPS), induce oxidative stress and pro-inflammatory cytokine production in the liver, which all contribute to NAFLD progression. In this study, we are evaluating the mRNA expression of genes associated with fatty acid oxidation (FAO) and the protein expression of pro-inflammatory cytokines related to NAFLD using the HepG2 human liver …

Background: Food systems are associated with severe and persistent problems worldwide. Governance approaches aiming to foster sustainable transformation of food systems face several challenges due to the complex nature of food systems. Scope and Approach: In this commentary we argue that addressing these governance challenges requires the development and adoption of novel research and innovation (R&I) approaches that will provide evidence to inform food system transformation and will serve as catalysts for change. We first elaborate on the complexity of food systems (transformation) and stress the need to move beyond traditional linear R&I approaches to be able to respond to …
