This paper defines a strong security model for multi-recipient signcryption scheme in the random oracle model, which is semantically secure against adaptive chosen-ciphertext insider attack, existentially forgeable chosen-message attack and anonymous chosen-ciphertext insider attack. By analyzing, we point out that Li-Hu-Liu Multi-Recipient Signcryption Scheme is insecure against the adaptive and anonymous chosen-ciphertext insider attacks.

摘要在随机预言模型下定义了一个多接收者签密方案的强安全性模型,该模型满足适应性选择密文内部攻击安全性、选择消息抗存在性伪造和密文匿名安全性;通过分析指出, Li、Hu和Liu等人提出的多接收者签密方案,不具有适应性选择密文内部攻击安全性和密文匿名性,并给出所定义强安全性模型中的攻击方法;随后提出改进方案,该方案在强安全模型中证明是安全的。

The existence of dextran sulphate to the native ovalbumin leads to decrease about 60% in fluorescence intensity following high pressure treatment. Complexation of polysaccharide with ovalbumin seems to protect the protein against pressure induced conformational change and aggregation; The presence of τ-carrageenan in glycinin solution is also found to protect the protein against pressure.

经超高压处理后,加入硫酸右旋糖苷的鸡蛋清蛋白溶液中的ANS荧光强度显著降低,降低约60%;这表明,硫酸右旋糖苷的加入可以和鸡蛋清蛋白相互作用,从而在超高压处理中起到稳定蛋白质天然构象的作用;对于大豆豆球蛋白溶液而言,ι-角叉菜胶的加入有维持高压下大豆豆球蛋白构象稳定性的作用。

华燕吟建议,要避免患上糖尿病,应尽量做到&四个一点&:多懂一点,即对糖尿病的知识多懂一点,积极主动地去预防糖尿病;少吃一点,要控制摄取的总热量,多吃蔬菜,少吃主食,高热量的副食也要少吃;多动一点,要经常保持一定的运动量,使身体不至于过胖;放松一点,心理不平衡会进一步加强胰岛素抵抗,促使糖尿病发生,好的心态对糖尿病有积极的预防作用。

In the insecticidal test, compounds 2-29 exhibited the most potent effect against Plutella xylostella and a moderate effect against Heliothis virescens.

在农业常见害虫的杀虫活性测试中,化合物2-29几乎完全抑制小菜蛾的生长,对 Heliothis virescens也有中等强度的抑制效果。

These results indicate that as a main effector, specific IgG play a key role against re-infected with homologous Plasmodium but haven't protection against re infected with heterogenic Plasmodium.

特异性IgG抗体可在宿主抗同源疟原虫再感染中发挥着重要作用,而对异种疟原虫再感染无保护性。

The pigment of Berberis heteropoda Schrenk is a type of anchocyanin and it is strong in resistance against light and to some extent, good in enduring heat and low consistence oxide. But it is poor in resistance against reductant and preservative. It can be applied to the condition of PH. It is also found that sucrose and most of metal ions do not exert negative effects on the stability of the pigment, except Fe3+, Fe2+and low consistence Pb2+, which have some extent effects. Adding stability matter can improve its stability. The harm trace elements contains are within requirement of the National Standard on food safety, As the lexicological study indicates that the pigment does not have any toxicity and mutagenesis, it can be used as edible pigment.

结果表明:大孔树脂吸附-解吸附法纯化黑果小檗色素实验室工艺简单易行,色素回收率高;黑果小檗色素属于花色苷类色素;耐光性好;对热有一定耐受性;对低浓度氧化剂有一定耐受性;耐还原性差;对防腐剂耐性差;适用PH<6条件下使用;蔗糖和大多数金属离子对色素无不良影响,但Fe~(3+)、Fe~(2+)、Sn~(2+)和低浓度pb~(2+)对色素有影响,加入稳定剂后,可提高色素的耐热性、耐氧化性、耐防腐剂能力;经对有害微量元素进行检测和毒理试验表明,该色素安全无毒,可以作为天然食用色素使用。

These results indicated that the rFPV-IFNγS1 could protect chickens against the challenge of the homotype strain but not against the challenge of the heterotype strain.

以上结果可以说明,重组疫苗能对同源强毒株产生较好的免疫保护,但不能对遗传关系较远的强毒株产生有效的免疫应答。

To evaluate the efficacy of the recombinant fowlpox virus vaccine against the heterotype IBV, the chickens were challenged with the homotype IBV LX4 strain and the heterotype IBV LTJ95I strain after three weeks post vaccination. Antibodies against IBV were detected in vaccinated chickens one week post inoculation. The CD4+ T-lymphocytes in the peripheral blood increased rapidly in all groups challenged with IBV, except for the vaccinated group challenged by heterotype strain and the low level of CD4+ T-lymphocytes remained until end of the experiment. In all the groups, a high level of CD8+ T-lymphocytes only was observed in the vaccinated group after challenging with IBVhomotype strain. The morbidity and the mortality of this group were 21.43 % and 0 %, respectively, which showed significant difference with other groups. In addition, the lesions of chickens and virus shedding were less in the vaccinated group challenged by IBV homotype strain comparing with other groups, but there was no difference for the average body weight of chickens in all groups.

结果显示,重组疫苗接种1周后,免疫鸡产生抗IBV的抗体;而且外周血中CD4+和CD8+ T淋巴细胞的含量略高于非免疫对照组;攻毒后,异源强毒株攻毒的免疫组CD4+ T淋巴细胞呈下降趋势,并且该组低水平CD4+的状态一直持续到试验结束,而其他组CD4+ T淋巴细胞均迅速上升,峰值达到14.5 %;同源强毒株攻毒的免疫组CD8+ T淋巴细胞呈高水平的表达,而其他组攻毒后均无明显变化;保护率结果显示,同源强毒株攻毒免疫组的发病率和死亡率为21.43 %和0 %,与其他各组相比均有显著差异;另外同源强毒株攻毒的免疫组病理损伤与异源强毒株攻毒的试验组相比明显减轻,其排毒时间和排毒量也均有所减少;强毒攻毒后所有试验组体重无显著差异。
