Machine-to-machine (M2M) communication plays a fundamental role in autonomous IoT (Internet of Things)-based infrastructure, a vital part of the fourth industrial revolution. Machine-type communication devices(MTCDs) regularly share extensive data without human intervention while making all types of decisions. Thesedecisions may involve controlling sensitive ventilation systems maintaining uniform temperature, live heartbeatmonitoring, and several different alert systems. Many of these devices simultaneously share data to form anautomated system. The data shared between machine-type communication devices (MTCDs) is prone to risk dueto limited computational power, internal memory, and energy capacity. Therefore, securing the data and devicesbecomes challenging due to factors such as dynamic operational environments, remoteness, harsh conditions,and areas where human physical access is difficult. One of the crucial parts of securing MTCDs and data isauthentication, where each devicemust be verified before data transmission. SeveralM2Mauthentication schemeshave been proposed in the literature, however, the literature lacks a comprehensive overview of current M2Mauthentication techniques and the challenges associated with them. To utilize a suitable authentication schemefor specific scenarios, it is important to understand the challenges associated with it. Therefore, this article fillsthis gap by reviewing the state-of-the-art research on authentication schemes in MTCDs specifically concerningapplication categories, security provisions, and performance efficiency.

为帮助食品生产商和消费者选择适用于不同应用途径的黄油,并为生产更受消费者喜爱的黄油替代品提供理论支持,选取了11个国家的黄油并提取黄油乳脂,对黄油及黄油乳脂的理化性质进行了系统的比较评价。结果表明:11个国家黄油中的脂肪、水分、蛋白质含量和滑动熔点分别为82.97%~86.40%、12.84%~16.14%、0.45%~0.78%、31.5~33.9℃,酸值(KOH)和过氧化值分别不超过0.32 mg/g、0.029 g/100 g。中国黄油的L值最高(86.87),而新西兰黄油的b值最高(35.28)。所有黄油共检出29种脂肪酸和42种甘油三酯,蛋白质主要由αs1-酪蛋白、β-酪蛋白、κ-酪蛋白、α-乳白蛋白和Adipophilin组成。爱尔兰黄油的不饱和脂肪酸含量最高(35.65%),固体脂肪含量(SFC)较低,而美国、荷兰和澳大利亚黄油的饱和脂肪酸和SFC含量较高。不同国家的黄油和黄油乳脂的晶体均为均匀精细的球晶,其中美国黄油和黄油乳脂的晶体均呈现部分聚集,且绝大多数晶体主要由β′型晶体组成。质地和流变学分析表明,爱尔兰黄油和黄油乳脂的硬度最低,所有黄油和黄油乳脂都表现出良好的黏弹性和剪切变稀性能。综上,不同国家黄油在基本理化性质、脂肪酸和甘油酯组成、SFC及硬度等方面存在差异,在食品工业中需要根据成品、加工工艺等有针对性地选择黄油,在新型人造奶油的构建中,也可依据各黄油特点进行定向研究。

不同国家的饲养方式及加工条件会在一定程度上影响黄油的理化性质，由此对其使用特性产生影响，但是目前极少有研究对此进行报道。本研究选取了11个国家的黄油并对其理化性质进行了系统的比较评价。黄油中的水分和蛋白质含量分别为12.84%-16.14%、0.45%-0.78%，且不同国家存在显著差异。中国黄油的颜色是最白的（L=86.87，b=14.19），而新西兰黄油的颜色则是最黄的（L=78.45，b=35.28）。爱尔兰黄油的不饱和脂肪酸含量最高（35.65%），固体脂肪含量（SFC）最低，而美国、荷兰和澳大利亚的黄油的饱和脂肪酸和SFC含量较高。不同国家的黄油晶体主要由β’晶体组成，中国、美国、法国和德国的黄油β’晶体含量相对较高。中国黄油的晶体最小，意大利黄油的晶体呈现部分聚集成，因而具有较大的晶体颗粒。质地和流变学分析表明，爱尔兰黄油的硬度最低（5 ℃，938.13 g；25 ℃，20.15 g），所有黄油都表现出良好的粘弹性和剪切变稀性能。本研究所得基础数据将有助于食品生产商和消费者选择适用于不同应用途径的黄油，并为生产更受消费者喜爱的黄油替代品提供支持。

鸡柔嫩艾美耳球虫(Eimeria tenella)是一种寄生于鸡盲肠的单细胞寄生性原虫,可导致鸡盲肠肠道出血,严重者引起死亡,对养禽业造成严重的经济损失。谷氨酸脱氢酶(Glutamate dehydrogenase,GDH)在细胞内信号转导、三羧酸循环、氨代谢和能量代谢等多种细胞生理过程中起重要的作用,最近有研究报道该蛋白可作为抗恶性疟原虫药物设计的潜在药靶。本研究在实验室前期克隆的鸡柔嫩艾美耳球虫谷氨酸脱氢酶基因(Etgdh)的基础上,将EtGDH酶活性位点突变,以确定探讨EtGDH的关键催化位点,为抗鸡球虫药物筛选提供研究基础。通过结构预测与同源性分析,筛选EtGDH的酶活性位点,构建了EtGDH-K133A等12个突变体。分别与载体pET-32a连接后构建pET-32a-EtGDH突变体重组质粒,重组质粒经PCR鉴定及测序,与预期结果一致。将测序正确的重组质粒转化至大肠杆菌*** Rosetta (DE3)菌株,将鉴定为阳性的*** Rosetta (DE3)(pET-32a-EtGDH突变体重组质粒)以0.1mM IPTG,16℃低温诱导表达,再以Ni-NTAHis Bind Resins纯化12个rEtGDH突变体蛋白。结果获得条带大小约为73 kDa的纯化目的蛋白。柔嫩艾美耳球虫GDH突变体的构建及重组表达,为后续明确EtGDH在酶催化功能上的意义及抗鸡球虫药物筛选方面奠定了一定基础。

本试验旨在研究两种微生态制剂产品H和B对雏鸡免疫鸡球虫病活卵囊弱毒疫苗的肠道保护效果。方法:挑选健康的1日龄岭南黄鸡,随机分为14组,分别为免疫给药组6组、免疫对照组、未免疫给药组6组、空白对照组。给药组分别在1～4日龄、8～11日龄、15～18日龄等三个时间段进行给药(H为饮水使用,B为拌料使用),采用平养模式,疫苗免疫组在4日龄统一饮水进行疫苗免疫。通过对比鸡11日龄和18日龄的OPG、鸡25日龄料肉比、增重率、病变积分、粪便计分及盲肠病理切片情况对两种药物进行肠道免疫保护评估;在26日龄各组鸡随机挑选10只进行攻虫保护实验,每只鸡感染1.2×10个Eimeria tenella孢子化卵囊。最终以抗球虫指数(ACI)作为药物效果的综合评定指标。结果:给药组鸡生长性能均优于未给药对照组,料肉比:未免疫给药组>空白对照组>免疫给药组>免疫对照组,说明球虫疫苗对鸡体确实存在病理损伤,且两种微生态制剂均对鸡肠道有正向调节作用;同种药物不同时间段给药对雏鸡影响为:1～25d给药效果>1～4、8～11、15～18多段时间给药>1～4d给药,且1～25d与1～4、8～11、15～18组效果不显著。实验结果表明:微生态制剂H和B均对鸡免疫鸡球虫病活卵囊弱毒苗的肠道有修复作用,结合生产实际,多段时间使用效果最好。本试验研究,为后期鸡球虫病活卵囊疫苗的临床使用提供一个新的优化思路。

鸡球虫病对养鸡业危害十分严重,每年给养鸡业造成巨大的经济损失,目前尚无根治措施,药物仍是主要防控手段,但是由于抗球虫药物的使用甚至滥用,鸡球虫的抗药性日趋广泛而严峻,为研究鸡球虫入侵机制及快速高通量筛选抗球虫制剂等,建立HCT-8细胞体外培养鸡球虫模型。将新鲜制备并纯化的柔嫩艾美耳球虫(Eimeria tenella)子孢子接种HCT-8细胞,于不同时间取样,制备细胞爬片并固定,分别进行HE染色和DAPI染色,观察子孢子在细胞中的发育状况。结果显示子孢子在接种后即可迅速入侵HCT-8细胞,6 h入侵的子孢子固定在细胞中,月牙形的子孢子发育逐渐变得钝圆,至48h第一代裂殖体形成,逐渐变大变圆直至成熟,到54 h释放第一代裂殖子,第一代裂殖子继续入侵细胞并发育,在72h形成第二代裂殖体,此后至144 h仍可观察到第二代裂殖子释放,培养到168 h均未见卵囊形成,相应的鸡体试验显示在144～168h可观察到大量卵囊排出体外,据此判断子孢子在细胞内的发育过程结束。结论***在HCT-8细胞中发育成第二代裂殖子,将子孢子在体外细胞中的发育阶段向前推进了一个进程,为鸡球虫相关研究工作的开展提供技术平台。
