Effects of Metformin on Ischemia/Reperfusion Injury: New Evidence and Mechanisms.

The search for new drugs with the potential to ensure therapeutic success in the treatment of cardiovascular diseases has become an essential pathway to follow for health organizations and committees around the world. In June 2021, the World Health Organization listed cardiovascular diseases as one of the main causes of death worldwide, representing 32% of them. The most common is coronary artery disease, which causes the death of cardiomyocytes, the cells responsible for cardiac contractility, through ischemia and subsequent reperfusion, which leads to heart failure in the medium and short term.

Mechanisms of the Quorum Sensing Systems of : Host and Bacteria.

Quorum-sensing is a communication mechanism between bacteria with the ability to activate signaling pathways in the bacterium and in the host cells. is a pathogen with high clinical relevance due to its vast virulence factors repertory and wide antibiotic resistance mechanisms. Due to this, it has become a pathogen of interest for developing new antimicrobial agents in recent years.
