Abstract: The present invention discloses a method for the preparation and application of modified extracellular vesicles specifically targeted to the kidneys. These modified extracellular vesicles are derived from fibroblastic reticular cells in the mesentery tissue and express anti-inflammatory proteins after being modified with anchor peptides. By combining the extracellular vesicles secreted from fibroblastic reticular cells in the mesentery tissue with anchor peptides, the present invention ensures the effective targeting of the exosomes to the kidneys. Additionally, through genetic engineering of fibroblastic reticular cells, the exosomes secreted by these cells can carry the target molecule, anti-inflammatory protein CD5L, achieving precise targeted therapy for the kidneys. This innovative treatment strategy holds promising potential for the treatment of sepsis-associated acute kidney injury, bringing positive impacts to patients' health.

Abstract: Techniques for controlling user data consumption are disclosed herein. An example method includes receiving a user connection to a network on-board a vehicle, the network being an on-board network; and executing a volume control with credit (VCC) algorithm. Executing the VCC algorithm includes provisioning a data credit for the user connection corresponding to an initial usage estimate, placing the user connection into a first mode, initiating a timer associated with the user connection, and iteratively provisioning additional data credits associated with the user connection based on the timer.

The position of the seat belt socket can be adjusted automatically as the frame of the zero-gravity seat rotates, reducing the feeling of oppression which the belt part of the seat belt engenders in the passenger's abdomen, and increasing the comfort and safety of the seat.
