Recently, a research team led by Professor Jian-Xun Wang and Professor Tao Yu from Qingdao University made a significant breakthrough in understanding the role of lactylation modification in aortic dissection (AD). Their study revealed that lactylation of the mitochondrial ATP synthase subunit alpha (ATP5F1A) at the K531 site promotes the development and progression of AD by impairing mitochondrial function and inducing a phenotypic switch in vascular smooth muscle cells (VSMCs). The related findings have been formally published.

In this study, we introduced parity transformation alone into metamaterial design. By pairing arbitrary asymmetric meta-atoms with their unique parity-inverted counterparts, they can be utilized to construct parity metamaterials. Under the joint protection of parity transformation and reciprocity, these metamaterials maintain undistorted transmitted wavefronts across ultrabroad frequency ranges.

A review article published by the Fudan University presented the most recent progress for these purposes, with an emphasis on material properties such as foreign body response, on integration schemes with biological tissues, and on their use as bioelectronic platforms.

The new review paper, published on Apr. 29 in the journal Cyborg and Bionic Systems, summarized an envisioned applications involve advanced implants for brain, cardiac, and other organ systems, with capabilities of bioactive materials that offer stability for human subjects and live animal models.
