Burns carry a large surface area, varying in shapes and depths, and an elevated risk of infection. Regardless of the underlying etiology, burns pose significant medical challenges and a high mortality rate. Given the limitations of current therapies, tissue-engineering-based treatments for burns are inevitable.

Glioblastoma multiforme (GBM) is a highly invasive and fatal brain tumor with a grim prognosis, where current treatment modalities, including postoperative radiotherapy and temozolomide chemotherapy, yield a median survival of only 15 months. The challenges of tumor heterogeneity, drug resistance, and the blood-brain barrier necessitate innovative therapeutic approaches. This study introduces a strategy employing biomimetic magnetic nanorobots encapsulated with hybrid membranes derived from platelets and M1 macrophages to enhance blood-brain barrier penetration and target GBM.

Alopecia areata (AA) is a prevalent autoimmune condition that causes sudden hair loss and poses significant psychological challenges to affected individuals. Current treatments, including corticosteroids and Janus kinase inhibitors, fail to provide long-term efficacy due to adverse effects and relapse after cessation. This study introduces a nanoparticle (NP) system that codeliver diphenylcyclopropenone (DPCP) and rapamycin (RAPA) prodrugs to induce immune tolerance and promote hair regeneration.

The traditional management of acute coronary syndrome has relied on the identification of ST-segment elevation myocardial infarction (STEMI) as a proxy of acute coronary occlusion. This conflation of STEMI with acute coronary occlusion has historically overshadowed non-ST-segment elevation myocardial infarction (NSTEMI), despite evidence suggesting 25% to 34% of NSTEMI cases may also include acute coronary occlusion. Current limitations in the STEMI/NSTEMI binary framework underscore the need for a revised approach to chest pain and acute coronary syndrome management.
