Pediatric Blood &Cancer, EarlyView.ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Synthesis of group I–III–VI semiconductor quantum dots and its application in food safety testing
Reviews in Analytical Chemistry, 2022 As a good fluorescent material, most I–III–VI ternary semiconductor quantum dots (QDs) do not contain heavy metal elements such as Cd and Pb and thus have low toxicity. In addition, they also have excellent data performance such as narrow band gap, large
