| 1 | The Flavor and Antioxidant Activity Change Pattern of Shrimp Head Paste During Fermentation显示文摘To study the changes of volatile compounds and antioxidant activity of fast fermented shrimp head paste during the fermentation processing,Penaeus vannamei boone head was used as the raw material,and compound starter was added for fermen-tation.During the 14 days of fermentation,the changes of free amino acids,volatile flavor compounds and main components were determined by SPME-GC-MS and electronic nose.The oxidation-resistance changes of water extract at different fermentation stages were evaluated.The results showed that the total free amino acids increased from original 2320 to 5640 mg(100 mL)^(−1).SPME-GC-MS analysis found that aldehydes,pyrazine compounds increased from 10.80%,1.94%to 24.35%,13.63%respectively during the fermentation process.The HO·scavenging ability of shrimp head paste increased from 52%to 86%.Our results showed that the shrimp paste produced from shrimp head fermentation could obtain good flavor and possess certain antioxidant activity of aquatic fermented condiment. | YU Jing LU Kuan SUN Jinyuan XIE Wancui SONG Lin CHE Hongxia | 2022 | Journal of Ocean University of China2022，21，1： | 2 |
| 2 | The double mutations of acvr2aa and acvr2ba leads to muscle hypertrophy in zebrafish显示文摘Activin A receptor,type II(Acvr2)is a member of the transforming growth factor beta receptor family and can function as a negative regulator of skeletal muscle mass.Acvr2 plays an important role in regulating muscle development that can inhibit skeletal muscle growth in mice.However,there is very little research reported on the function of acvr2 in muscle development of teleost.In this study,we analyzed the effect of acvr2aa and acvr2ba on muscle development in zebrafish.Growth rates of WT and acvr2a^(-/-b-/-)��were measured from juvenile stage to adult stage.In addition,effects of acvr2 on skeletal muscle were tested in histological,protein and molecular levels.As a result,acvr2a^(-/-b-/-)��exhibited a wider body trunk than WT and showed a significant increase in body weight and width from two months old.Histological analysis of skeletal muscle indicated that the size of muscle fiber in acvr2a^(-/-b-/-)��(female:1809±123μm^(2);male:2261±130μm^(2))was larger than that in WT(709.8±49μm^(2);815±53μm^(2)).In addition,western blot of fast MyLc protein showed the protein synthesis of acvr2a^(-/-b-/-)��are increased.Besides,Histological analysis of heart showed the ventricle area is aslo increased in acvr2a^(-/-b-/-)��.Our results demonstrated acvr2 attends the development of muscle fiber and will cause muscle hypertrophy when they were knocked out in zebrafish.In conclusion,acvr2 in zebrafish can control the development of muscle fibers during posthatch growth. | Jinyuan Che Cunjie Hu Qi Wang Chunxin Fan Yufeng Si Xiaoling Gong Baolong Bao | 2023 | Aquaculture and Fisheries2023，8，6： | 0 |
