The CTMax was estimated at three different heating rates including 0.5℃ min^(-1), 1℃ h^(-1) and 2℃ d^(-1). Results showed that the CTMax of maple trout(Oncorhynchus mykiss) was the highest, which was followed by steelhead trout(O. mykiss) and Atlantic salmon(Salmon salar). The CTMax of the salmonid fish decreased with the increment of body weight, and was significantly influenced by the heating rate. The MO_2 of the salmonid fish increased with the increment of temperature, and decreased with the increment of body weight. Suffocation points of the fish decreased with increasing body weight and temperature. Steelhead trout was more tolerant to hypoxia than maple trout and Atlantic salmon, while the MO_2 of Atlantic salmon was the highest among these three salmonids. The LOS of the fish generally had a positive trend with temperature and body weight, and the LOS of steelhead trout was significantly lower than that of maple trout and Atlantic salmon. In conclusion, maple trout was the most tolerant kind to high temperature, while steelhead trout was the most tolerant to hypoxia among three kinds of salmonids. Moreover, the abilities to tolerate higher temperature of three salmonids were affected by their body weight and the heating rate, while the abilities to tolerate hypoxia were influenced by their body weight and the water temperature.展开更多

He had choked on sushi and collapsed in the dining room of a mental hospital. A nursing assistant summoned a physician who attempted to extract the sushi. External cardiac massage was initiated after 7 minutes had elapsed and followed by endotracheal intubation. Return of spontaneous circulation was achieved after 7 minutes of resuscitation. A bronchoscopy demonstrated a large amount of shari in the trachea and right bronchus, which was removed with alligator forceps and a wire basket.RESULTS: Neurological recovery was evident on day 2 of admission. He was transferred back to the mental hospital with no neurological complications.CONCLUSION: Emergency physicians should consider sushi suffocation, including its clinical features and management.展开更多

Will these actions damage China's national interests and is it necessary for China to set a bottom line in this field? Yang Fan, a professor at the China University of Political Science and Law, and He Maochun, Director of the Research Center of Economy and Diplomacy, Tsinghua University, were recently published in the Global Times, analyzing the impact of foreign M&A deals on China's economy from different perspectives.
