On the cover: In recent years, driven by the new round of scientific and technological revolution, the transportation industry is undergoing unprecedented and significant changes. Emerging transport vehicles include autonomous vehicle and flying car. Some innovative operational modes appear, like Mobility as a Service and shared mobility. Meanwhile, advanced informatics technology, such as Artificial Intelligence and the Internet of Things, is also joining the way to make a better traffic. All of the progress has facilitated the emergence of Advanced Urban Aerial Mobility, a new paradigm for future transportation. The system is based on providing high-quality services as its core and the principles of energy-saving and environmental protection, making urban travel more enjoyable. This common scene in science fiction is no longer far-reaching. |

Systemic administration of biologically engineered EVs for ischemic stroke
Nanotechnology-based therapeutic strategies have been proven effective in diseases including cancer, infection, inflammation, etc. However, the application of nanotechnology is greatly restricted in the treatment of central nervous system (CNS) disorders due to physiological CNS barriers. For example, the blood-brain barrier (BBB) can be the ¡°Maginot line¡± for pharmacologically active molecules, blocking them out of the CNS. Besides, the neuroinflammation and non-directional differentiation of neural stem cells (NSCs) during neurological disorders could also affect neuronal activity and even produce fibrotic scars, thus hindering the CNS regeneration process.
