Atherothrombosis and Oxidative Stress: Mechanisms and Management in Elderly [PDF]
Significance: The incidence of cardiovascular events (CVEs) increases with age, representing the main cause of death in an elderly population. Aging is associated with overproduction of reactive oxygen species (ROS), which may affect clotting and ...

The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...
