The Role and Underlying Mechanisms of Exercise in Heart Failure.

Heart failure is a prevalent and life-threatening syndrome characterized by structural and/or functional abnormalities of the heart. As a global burden with high rates of morbidity and mortality, there is growing recognition of the beneficial effects of exercise on physical fitness and cardiovascular health. A substantial body of evidence supports the notion that exercise can play a protective role in the development and progression of heart failure and improve cardiac function through various mechanisms, such as attenuating cardiac fibrosis, reducing inflammation, and regulating mitochondrial metabolism.

[Effects of successive cropping Rehmannia glutinosa on rhizosphere soil microbial flora and enzyme activities].

With the soils cropped Rehmannia glutinosa for one and two years as test materials, this paper studied the variations of microbial flora and enzyme activities in rhizosphere. The results showed that with increasing year of cropping, the numbers of bacteria and fungi in rihzosphere had a slight decrease. In the soil successively cropped R.
