Ischemic-Preconditioning Induced Serum Exosomal miR-133a-3p Improved Post-Myocardial Infarction Repair via Targeting LTBP1 and PPP2CA.

Background: Ischemic preconditioning-induced serum exosomes (IPC-exo) protected rat heart against myocardial ischemia/reperfusion injury. However, whether IPC-exo regulate replacement fibrosis after myocardial infarction (MI) and the underlying mechanisms remain unclear. MicroRNAs (miRs) are important cargos of exosomes and play an essential role in cardioprotection.

Efficient Carrier Transport in 2D BiOSe/CsBiI Perovskite Heterojunction Enables Highly-Sensitive Broadband Photodetection.

2D BiOSe has recently garnered significant attention in the electronics and optoelectronics fields due to its remarkable photosensitivity, broad spectral absorption, and excellent long-term environmental stability. However, the development of integrated BiOSe photodetector with high performance and low-power consumption is limited by material synthesis method and the inherent high carrier concentration of BiOSe. Here, a type-I heterojunction is presented, comprising 2D BiOSe and lead-free bismuth perovskite CsBiI, for fast response and broadband detection.
