Cocoa is a rich source of high-quality antioxidant polyphenols. They comprise mainly catechins (29%-38% of total polyphenols), anthocyanins (4% of total polyphenols) and proanthocyanidins (58%-65% of total polyphenols). A growing body of experimental and epidemiological evidence highlights that the intake of cocoa polyphenols may reduce the risk of cardiovascular events. Beyond antioxidant prop...

During hepatic fibrogenesis, quiescent hepatic stellate cells (HSC) become active and trans-differentiate into myofibroblast-like cells. This process coincides with an increase in cell proliferation, loss of stored vitamin A droplets, and excessive production and deposition of extracellular matrix components. HSC activation is coupled with the sequential expression of cytokine receptors, includ...

Diabetes mellitus (DM) is one of the most important health problems with increasing prevalence worldwide. Oxidative stress that is a result of imbalance between reactive oxygen species (ROS) generation and antioxidant defense mechanisms has been demonstrated as a main pathology in DM. Hyperglycemia-induced ROS productions can induce oxidative stress through four major molecular mechanisms inclu...
