摘要: The invention relates to blood substitute compositions, and methods of use thereof. Described herein are compositions in which hemoglobin is maintained substantially in the reduced form of hemoglobin as opposed to the oxidized methemoglobin form through inclusion of an oxido-reductase enzyme and reducing agent within a vesicle with the hemoglobin. The vesicles additionally can comprise a dismutase, a catalase, and an electron acceptor, each of which contribute to either the maintenance of hemoglobin in the active oxygen carrying state or provide a benefit not achieved with free hemoglobin.

摘要: The present disclosure discloses a switching mode power supply with constant peak current mode control. During the operation of the switching mode power supply, in one hand, the current flowing through a high-side switch is sensed and compared to a current reference signal to control the turning off of the high-side switch; in the other hand, the output voltage is sensed and compared to a voltage reference signal to control the turning on of the high-side switch. In addition, the current reference signal may be adjusted to a lower value when the switching mode power supply enters light load condition. By using the above control method, the system performance is highly increased.
