Potential influence of blueberry and black raspberry pomace phenolics on inflammatory cytokines in coronary cells
Elevated free fatty acids (FFAs) in obesity are known risk factors associated with chronic inflammatory conditions including cardiovascular inflammation and thus cardiovascular disease (CVD), the leading cause of death in the US. Anthocyanins from berries have the potential to provide protection …

Benzoic acid regulates the physio-biochemical responses of chia (Salvia hispanica L.) seedlings under salinity stress
… adaptive strategies, including the secretion of phenolic acids in response to environmental stresses. Phenolic acids can be categorised into different subclasses based on their chemical structures, such as hydroxybenzoic acids and hydroxycinnamic acids. Among them, benzoic acid (B.A) serves as a …
