α-Substituted vinyl azides: An emerging functionalized alkene
No full textVinyl azides are highly versatile synthons that provide access to numerous N-heterocycles and other functional groups. a-Substituted vinyl azides (azido vinylidenes) are a special class that display unique reactivity, able to react not only as azides, but also as radical acceptors, enamine-type nucleophiles, and even electrophiles, thus delivering a wide range of nitrogen-containing compounds and their derivatives. An impressive variety of intermediates – such as iminodiazonium ions, nitrilium ions, iminyl radicals, and metal enaminyl radicals – can be generated from vinyl azides and exploited in cycloadditions, C–H functionalizations, hydrolysis processes, and cascade reactions under transition metal/photoredox catalysis. In addition to presenting synthetic protocols to access vinyl azides, this Review offers a comprehensive coverage of the development of their multifaceted reactivity, and highlights their potential as versatile precursors for synthetic applications

Spaceborne Bi- and Multistatic SAR: Potential and Challenges
No full textBi- and multistatic synthetic aperture radar (SAR) operates with distinct transmit and receive antennas that are mounted on separate platforms. Such a spatial separation has several operational advantages, which will increase the capability, reliability and flexibility of future SAR missions. Various spaceborne bi- and multistatic SAR configurations are introduced, and their potential for different applications such as frequent monitoring, wide-swath imaging, scene classification, single pass cross-track interferometry and resolution enhancement is compared. Furthermore, some major challenges such as phase and time synchronisation, bi- and multistatic SAR processing, satellite orbit selection and relative position sensing are addressed

Novel application of CHUANG BI FU biologic protein sponge in promoting peripheral nerve injury repair by regulating vascular regeneration
No full textAbstract Background The search for effective drugs that promote regeneration after peripheral nerve injury (PNI) has received widespread attention, but little attention has been paid to the potential secondary damage to nerves during neurosurgical procedures. CHUANG BI FU Biologic Protein Sponge (CHUANG BI FU) is a composite biological sponge loaded with basic fibroblast growth factor (bFGF) that has been effectively applied to clinical wounds, but has never been used for repairing peripheral nerves. Methods This study used a 3.5-mm nerve defect model in mice, and wrap CHUANG BI FU around the nerve defect site, connecting the distal and proximal ends of the damaged nerve without suturing the nerve. The repair function of the nerve by the wound was tested by detecting mouse footprints, electrophysiology, NF200 staining, CD31 staining, and gastrocnemius muscle Masson staining. Results It was found that CHUANG BI FU can promote axonal elongation, promote neuromuscular reinnervation function, and promote angiogenesis of regenerating nerves, thereby achieving the function of promoting damaged nerve regeneration. And through cellular level research, it was found that CHUANG BI FU may promote vascular regeneration through the PI3 K–AKT pathway. Conclusions Using CHUANG BI FU to repair peripheral nerves can promote vascular regeneration through the PI3 K–AKT pathway and it can greatly reduce the technical difficulty and operation time required by surgical operators
