Puerarin, a traditional Chinese medicine, exerts a powerful neuroprotective effect in cerebral ischemia/reperfusion injury, but its mechanism is unknown. Here, we established rat models of middle cerebral artery ischemia/reperfusion injury using the suture method. Puerarin (100 mg/kg) was administered intraperitoneally 30 minutes before middle cerebral(More)
Animals behave differently in response to visual cues with distinct ethological meaning, a process usually thought to be achieved through differential visual processing. Using a defined zebrafish escape circuit as a model, we found that behavior selection can be implemented at the visuomotor transformation stage through a visually responsive(More)
The performance of large-scale cognitive radio (CR) networks with secondary users sustained by opportunistically harvesting radio-frequency (RF) energy from nearby primary transmissions is investigated. Using an advanced RF energy harvester, a secondary user is assumed to be able to collect ambient primary RF energy as long as it lies inside the harvesting(More)
The genus Compterosmittia Sæther, 1981 from China is reviewed. Three new species, C. duodecima sp. n., C. lii sp. n. and C. procera sp. n. are described as adult males. C. nerius (Curran, 1930), C. oyabelurida (Sasa, Kawai et Ueno, 1988) and C. togalimea (Sasa et Okazawa, 1992) are recorded from China for the first time and annotated; as a result the(More)
Among various types of behaviors, locomotion is the foundation for exploration, navigation, foraging, and approaching. Proper locomotion enables animals to move from one place to another via a sequence of actions and is essential for their survival. An excess, paucity, or imbalance of movements is considered to be a movement disorder which can impair the(More)
