Myocardial ischemia/reperfusion (IR) injury is a common adverse event in the clinical treatment of myocardial ischemic disease. Autosis is a form of cell death that occurs when autophagy is excessive in cells, and it has been associated with cardiac IR damage. This study aimed to investigate the regulatory mechanism of circRNA CDR1AS on autosis in cardiomyocytes under IR.

Atrial fibrillation (AF) is the most common sustained arrhythmia which brings a heavy burden to the lives and health of patients worldwide. Our earlier research documented cardiac conduction regulatory RNA (CCRR) as an antiarrhythmic lncRNA in heart failure. Here, we report that CCRR was decreased in atrial tissue after MI, MYZAP, and Nav1.

Cardiac conduction regulatory RNA (CCRR) has been documented as an antiarrhythmic lncRNA in our earlier investigation. This study aimed to evaluate the effects of CCRR on SERCA2a and the associated Ca homeostasis in myocardial infarction (MI). Overexpression of CCRR via AAV9-mediated delivery not only partially reversed ischemia-induced contractile dysfunction but also alleviated abnormal Ca homeostasis and reduced the heightened methylation level of SERCA2a following MI.

Background: Timely and proper suppression of inflammation can effectively reduce myocardial injury and promote the postmyocardial infarction (post-MI) wound-healing process. We have previously found that cardiac conduction regulatory RNA (CCRR), a long noncoding RNA (lncRNA) transcribed by the gene located on chromosome 9, with abundant expression in the heart, elicits antiarrhythmic effects in heart failure, and this is a continuing study on the role of CCRR in MI.

Methods: CCRR was overexpressed in CCRR transgenic mice or after injection of adeno-associated virus-9 (AAV-9).

Ecological environment quality is increasingly becoming a critical priority in measuring the sustainable development of modern cities. Reflecting on the reality of contemporary urban development, we create a structural equation model with city image and ecological quality as the antecedents of sustainable urban development, reflect on and expand the existing models of sustainable urban development, and further explore the mechanisms of various urban marketing factors on the shaping of city image. The study found that the continuous improvement of city marketing assets contributes to the process of shaping sustainable city branding.

In recent years, Wenzhou City located on the southeast coast of China has experienced the largest scale of land reclamation projects in China. However, the extent to which such projects still bring about the destruction of marine resources and the environment. So, in this study, a marine ecological development carrying capacity index model was established and analyzed the ecological carrying capacity index of the reclaimed sea area in Wenzhou with the detection and warning conditions to propose a marine ecological protection supervision mechanism.
