    Notes: Many epidemiological studies indicate that consumption of dietary polyphenolic compounds is beneficial in the prevention of cardiovascular diseases. Xanthones are a class of polyphenolic compounds that commonly occur in plants and have been shown to have extensive biological and pharmacological activities. Recently, the pharmacological properties of xanthones in the cardiovascular system have attracted great interest. Xanthones and xanthone derivatives have been shown to have beneficial effects on some cardiovascular diseases, including ischemic heart disease, atherosclerosis, hypertension and thrombosis. The protective effects of xanthones in the cardiovascular system may be due to their antioxidant, antiinflammatory, platelet aggregation inhibitory, antithrombotic and/or vasorelaxant activities. In particular, the antagonism of endogenous nitric oxide synthase inhibitors by xanthones may represent the basis for improved endothelial function and for reduction of events associated with atherosclerosis.

    Notes: Based on the proposed 4PUS-1RPU parallel mechanism a 5-axis Parallel KinematicMachine (PKM) scheme has been developed and the dynamic characteristics of the PKM have beeninvestigated in detail. To avoid the intensive computation caused by finite element analysis in theresearch, two typical metamodeling techniques of Response Surface Methodology (RSM) and itsartificial neural network enhanced technique were employed as the robust design approaches.Comparing the results obtained from the direct RSM the modeling accuracy by the artificial neuralnetwork enhanced RSM can be improved
