Recent Advances on Selenium Nutrition and Keshan Disease
Int Heart J. 2024;65(2):173-179. doi: 10.1536/ihj.23-628.ABSTRACTKeshan disease (KD) is a type of endemic cardiomyopathy with an unknown cause. It is primarily found in areas in China with low selenium levels, from northeast to southwest. The nutritional biogeochemical etiology hypothesis suggests that selenium deficiency is a major factor in KD development. Selenium is important in removing free radicals and protecting cells and tissues from peroxide-induced damage. Thus, low environmental selenium may affect the selenium level within the human body, and selenium level differences are commonly observed between healthy peo...

B-Type Natriuretic Peptide Inhibits the Expression and Function of SERCA2a in Heart Failure
Int Heart J. 2024;65(2):292-299. doi: 10.1536/ihj.23-144.ABSTRACTB-type natriuretic peptide (BNP) possesses protective cardiovascular properties; however, there has not been sufficient serious consideration of the side effects of BNP. As for sarcoplasmic/endoplasmic reticulum calcium ATPase 2a (SERCA2a), it was once considered a new target for the treatment of heart failure (HF). Nevertheless, clinical trials of SERCA2a gene therapy in HF have finally become unsuccessful. Research has found that elevated BNP levels and decreased SERCA2a expression are two important HF characteristics, which are always negatively correlated...
