Methods: 990 patients with AMI, including 386 with non-ST-segment elevation myocardial infarction (NSTEMI) and 604 with segment elevation myocardial infarction (STEMI) were recruited between January 2019 and March 2022. The in-hospital acute heart failure (AHF) and arrhythmia events were recorded.

Exploring a new mechanism between lactate and VSMC calcification: PARP1/POLG/UCP2 signaling pathway and imbalance of mitochondrial homeostasis.

Lactate leads to the imbalance of mitochondria homeostasis, which then promotes vascular calcification. PARP1 can upregulate osteogenic genes and accelerate vascular calcification. However, the relationship among lactate, PARP1, and mitochondrial homeostasis is unclear.

Conditional editing of the genome using single transcripts expressing Cas9 and sgRNA.

The CRISPR/Cas9(clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR- associated protein 9) system, a highly efficient, simple, and easy genome editing technology, offers significant potential for genetic engineering and has been commonly applied in gene function studies in . However, when using CRISPR/Cas9 system to edit gene, Cas9 and sgRNA expression elements exist in different individuals, and Cas9 and sgRNA must be integrated into an individual through a complex genetic hybridization process, which has a long and complex operation cycle In this study, on the basis of the CRISPR/Cas9 system, we introduced the tRNA-sgRNA system and triplex elements, used triplex elements to link Cas9 and tRNA-sgRNA genes, stabilized the end of Cas9 mRNA after single transcript cutting, and made the expression of both Cas9 protein and sgRNA with a single transcript a reality. And as we obtained the corresponding phenotypic progeny in one hybridization, genetic manipulation was simplified.

Ultralow loss hollow-core negative curvature fibers with nested elliptical antiresonance tubes.

Hollow-core negative curvature fibers can confine light within air core and have small nonlinearity and dispersion and high damage threshold, thereby attracting a great deal of interest in the field of hollow core fibers. However, reducing the loss of hollow-core negative curvature fibers is a serious problem. On this basis, three new types of fibers with different nested tube structures are proposed in the near-infrared spectral regions and compared in detail with a previously proposed hollow-core negative curvature fiber.
