| 1 | Maillard reaction in Chinese household-prepared stewed pork balls with brown sauce:potentially risky and volatile products显示文摘The stewed pork balls with brown sauce(SPB-BS)in China is well known for its delicacy and preferred by consumers.Maillard reaction(MR)is widespread in SPB-BS due to the use of sugar,meat and sauce in the thermal process.However,there is a lack of research on its risk and flavor by MR.By solid phase extraction combined with HPLC-MS,4 kinds of harmful compounds including acrylamide(AA),heterocyclic aromatic amines(HAAs),4-methylimidazole(4-MEI)and furan were analyzed in SPB-BS and their amounts ranged 0.05–0.50 mg/kg.The quantitative formula was proposed to evaluate the risk value of the SPB-BS,after taking into account the content,acceptable daily intake(ADI)and carcinogenicity of each compound.The risk values were in range of 0.57–37.93,suggesting that the risk caused by MR in SPB-BS was low.By head space-solid phase microextraction combined with GC-MS,57 volatile compounds in SPB-BS were identified with the dominant contribution of alcohols,aldehydes,acids and esters.Based on the structures of these compounds and the composition of SPB-BS,lipid oxidation and MR are inferred to be responsible for the formation of the harmful and volatile compounds.In addition,the added sauces and oil provides the main precursors to form the harmful and volatile compounds in SPB-BS,so it is necessary to point out a balance between them in the further study. | He Li Xiangyi Tang Chunjian Wu Shujuan Yu | 2021 | Food Science and Human Wellness2021，10，2： | 2 |
| 2 | Novel function of perforin in negatively regulating CD4^+ T cell activation by affecting calcium signaling显示文摘Perforin 是主要从事调停的形成毛孔的蛋白质目标 T 房间死亡并且被细胞毒素的 T 淋巴细胞(CTL ) 和自然漂亮房间采用。然而,它是否也在常规 CD4+ T 房间功能起一个作用,仍然保持不清楚。这里,我们报导那在 perforin 缺乏(PKO ) 老鼠, CD4+ T 房间是响应 T 的 hyperproliferative 房间受体(TCR ) 刺激。hyperproliferation 的这个特征被改进在房间分割并且在 IL-2 分泌物伴随。看起来, perforin 缺乏不在胸腺怒气和淋巴节点影响 T 房间开发。在 vivo, perforin 缺乏导致增加的抗原特定的 T 房间增长和抗体生产。而且, PKO 老鼠更产生试验性的自体免疫的眼色素层炎。探讨分子的机制,我们发现在 TCR 刺激以后,从 PKO 老鼠的 CD4+ T 房间显示增加的细胞内部的钙流动并且随后提高抄写因素 NFAT1 的激活。我们的结果显示 perforin 在由影响 TCR 依赖的 Ca2+ 发信号调整 CD4+ T 房间激活和有免疫力的反应起一个否定作用。 | Enguang Bi Chunjian Huang Yu Hu Xiaodong Wu Weiwen Deng Guomei Lin Zhiduo Liu Lin Tian Shuhui Sun Kairui Mao Jia Zou Yuhan Zheng Bing Sun | 2009 | Cell Research2009，19，7： | 2 |

| 8 | Development of Neural Network for BLSOM Clustering of HA Genes of Avian Influenza Viruses Isolated in Guangdong Province显示文摘A neural network classification method,and a batch-learning self-organizing map(BLSOM),was established using trinucleotide and tetranucleotide in the hemagglutinin gene sequences of 25 avian influenza viruses isolated in Guangdong Province. Statistical analysis and normalization of the fragment number were done and MATLAB function was used to simulate the human brain thinking for self-organizing learning. When the number of training steps was 100 and above,the strains could be successfully clustered. H_1,H_3,H_5,H_7 and H_9 subtype strains fell within different classes,respectively,and the HA gene cluster map of H_3N_2 and H_7N_9strains was quite similar,suggesting that these strains shared the same origin; H_5N_1 strain was quite different in different years; H_1N_1 and H_9N_2 strains could be clustered into one group,indicating the natural recombinant variation in the two kinds of viruses,thereby providing a reference for high-risk strain screening and traceability. | Chunjian TIAN Qiong LUO Jiahui GAO Zhixiong LIN Haiqiong YU Zhiling LIU Ru CHEN Xiaowei WU | 2016 | Asian Agricultural Research2016，8，11： | 0 |
