β(3)‐Adrenoceptors in the normal and diseased urinary bladder—What are the open questions?
2019
β(3)‐Adrenoceptor agonists are used in the treatment of overactive bladder syndrome. Although the relaxant response to adrenergic stimulation in human detrusor smooth muscle cells is mediated mainly via β(3)‐adrenoceptors, the plasma concentrations of the therapeutic dose of mirabegron, the only clinically approved β(3)‐adrenoceptor agonist, are considerably lower than the EC(50) for causing direct relaxation of human detrusor, suggesting a mechanism of action other than direct relaxation of detrusor smooth muscle. However, the site and mechanism of action of β(3)‐adrenoceptor agonists in the bladder have not been firmly established. Postulated mechanisms include prejunctional suppression o…
The roles of gut microbiota and circadian rhythm in the cardiovascular protective effects of polyphenols
2019
Polyphenols are secondary metabolites of plants that have been widely studied for their health benefits as antioxidants. In the last decade, several clinical trials and epidemiological studies have shown that long-term consumption of polyphenol-rich diet protects against chronic diseases such as cancers and cardiovascular diseases. Current cardiovascular studies have also suggested an important role of gut microbiota and circadian rhythm in the pathogenesis metabolic and cardiovascular diseases. It is known that polyphenols can modulate the composition of core gut microbiota and interact with circadian clocks. In this article, we summarize recent findings, review the molecular mechanisms an…
