Trimetazidine: Activating AMPK Signal to Ameliorate Coronary Microcirculation Dysfunction after Myocardial Infarction.

Background: Myocardial ischemia-reperfusion (I/R) injury and coronary microcirculation dysfunction (CMD) are observed in patients with myocardial infarction after vascular recanalization. The antianginal drug trimetazidine has been demonstrated to exert a protective effect in myocardial ischemia-reperfusion injury.

Objectives: This study aimed to investigate the role of trimetazidine in endothelial cell dysfunction caused by myocardial I/R injury and thus improve coronary microcirculation.

A novel strategy for the protective effect of ginsenoside Rg1 against ovarian reserve decline by the PINK1 pathway.

Context: The decline in ovarian reserve is a major concern in female reproductive health, often associated with oxidative stress and mitochondrial dysfunction. Although ginsenoside Rg1 is known to modulate mitophagy, its effectiveness in mitigating ovarian reserve decline remains unclear.

Objective: To investigate the role of ginsenoside Rg1 in promoting mitophagy to preserve ovarian reserve.

Internal Integrated Temperature Sensor for Lithium-Ion Batteries.

Lithium-ion batteries represent a significant component of the field of energy storage, with a diverse range of applications in consumer electronics, portable devices, and numerous other fields. In view of the growing concerns about the safety of batteries, it is of the utmost importance to develop a sensor that is capable of accurately monitoring the internal temperature of lithium-ion batteries. External sensors are subject to the necessity for additional space and ancillary equipment.

Recent Progress in Enzyme Immobilization to Metal-Organic Frameworks to Enhance the CO Conversion Efficiency.

Climate change and the energy crisis, driven by excessive CO emissions, have emerged as pressing global challenges. The conversion of CO into high-value chemicals not only mitigates atmospheric CO levels but also optimizes carbon resource utilization. Enzyme-catalyzed carbon technology offers a green and efficient approach to CO conversion.
