A seal arrangement for a tire pressure-regulating device for a motor vehicle, which provides a compressed-air supply to a tire of a vehicle through a hole in an inner ring of a rolling bearing of a wheel bearing, through a seal housing which is connected to a wheel hub in a rotationally fixed manner, and through the wheel hub itself. The invention dynamically switches between Infrastructure mode and Ad-hoc mode to balance system resources, improve QoS, reduce the communication traffic, waiting time and the cost of the users, and increase the income of the provider of the network service. Several improvements are included in this present invention to overcome the disadvantages of prior-art flyback power converters. IL-10 demonstrates the capacity to inhibit pro-inflammatory cytokine production in amniochorionic membranes in vitro as well as the capacity to inhibit uterine contractility and preterm labor in rhesus monkeys in vivo.
