A Case of Syncope in a Child due to the Large Segment of Myocardial Bridge.

We report a child with an unusual coronary bridge crossing over the left anterior descending (LAD), circumflex (CX), and right coronary artery (RCA). The bridges range from 0.8-1.

A self-assembled DNA nanostructure as a FRET nanoflare for intracellular ATP imaging.

Due to the incorporation of gold nanoparticles (AuNPs), previously reported AuNP-based FRET nanoflares still have some problems, such as non-negligible cytotoxicity and a time-consuming preparation procedure. In this communication, a novel AuNP-free FRET nanoflare for intracellular ATP imaging is developed based on a DNA nanostructure, which is self-assembled through cyclic U-type hybridization only involving a certain number of DNA strands.

Dual-MicroRNA-regulation of singlet oxygen generation by a DNA-tetrahedron-based molecular logic device.

Endogenous miRNA expression patterns are extremely cell-type-specific, thereby offering high prediction accuracy for different cell identities. Here, a DNA-tetrahedron-based "AND" logic gate is utilized as a molecular device that recognizes dual-miRNA inputs through strand hybridization to activate a computation cascade that produces controlled singlet oxygen in live cells, resulting in the death of the target cell.

Photocaged FRET nanoflares for intracellular microRNA imaging.

In 2015, we proposed FRET nanoflares for intracellular molecular (RNA, H, and K) detection. To improve detection accuracy and achieve on-demand sensing, herein, we developed photocaged FRET nanoflares for spatiotemporal microRNA imaging in living cells. In other words, the probes will not work until they are exposed to UV light.
