Background Ginkgo biloba extract(GBE)is evidenced to be effective in the prevention and alleviation of metabolic disorders,including obesity,diabetes and fatty liver ***,the role of GBE in alleviating fatty liver hemorrhagic syndrome(FLHS)in laying hens and the underlying mechanisms remain to be ***,we investigated the effects of GBE on relieving FLHS with an emphasis on the modulatory role of GBE in chicken gut *** The results showed that GBE treatment ameliorated biochemical blood indicators in high-fat diet(HFD)-induced FLHS laying hen model by decreasing the levels of TG,TC,ALT and *** lipid accumulation and pathological score of liver were also relieved after GBE ***,GBE treatment enhanced the antioxidant activity of liver and serum by increasing GSH,SOD,T-AOC,GSH-PX and reducing MDA,and downregulated the expression of genes related to lipid synthesis(FAS,LXRα,GPAT1,PPARγand Ch REBP1)and inflammatory cytokines(TNF-α,IL-6,TLR4 and NF-κB)in the *** profiling analysis revealed that GBE treatment reshaped the HFD-perturbed gut microbiota,particularly elevated the abundance of Megasphaera in the ***,targeted metabolomic analysis of SCFAs revealed that GBE treatment significantly promoted the production of total SCFAs,acetate and propionate,which were positively correlated with the GBE-enriched gut ***,we confirmed that the GBE-altered gut microbiota was sufficient to alleviate FLHS by fecal microbiota transplantation(FMT).Conclusions We provided evidence that GBE alleviated FLHS in HFD-induced laying hens through reshaping the composition of gut *** findings shed light on mechanism underlying the anti-FLHS efficacy of GBE and lay foundations for future use of GBE as additive to prevent and control FLHS in laying hen industry.

企业创新依赖于知识,然而存在于知识网络中不同形态的知识对企业创新绩效的作用尚未充分阐明。本文从知识形态角度以东湖高新区高新技术企业为研究对象,构建企业知识流量、知识存量与创新绩效的概念模型,探索不同形态知识间的作用关系以及与创新绩效的作用机理。结果显示:(1)知识存量与企业创新绩效呈倒U型关系;(2)内部自主研发形成的知识流量和外部协同研发形成的知识流量均与企业创新绩效呈正相关关系;(3)知识存量在自主研发形成的知识流量与创新绩效间起到正向调节作用,而对协同创新形成的知识流量与企业创新绩效起到负向调节作用。基于此,本文从企业研发策略、知识获取途径和形态动态转化角度提出相关建议。

辽东半岛新元古界震旦系甘井子组叠层石出露完好,宏观形态完整,微观构造清晰,是研究新元古代微生物碳酸盐岩建造的理想对象,对恢复古环境和古生态研究具有重要意义。笔者等选择甘井子组地层为研究对象,根据岩性特征该组自上而下可分成3段。叠层石出露于下段的底部和上段的顶部,底部叠层石为透镜状,顶部叠层石呈大规模层状。下段叠层石呈现波纹状—柱状—丘状的形态组合,上段叠层石呈现波纹状—柱状—长柱状的形态组合,均为水深不断增加的结果。笔者等通过对比现代叠层石生长机制,确定甘井子组叠层石纹层的3层构造和形成顺序,分析硬质基底对于叠层石定殖和叠层石密集生长的控制,厘定环境变化从微观到宏观对于柱体形态和叠层石规模的影响,揭示了甘井子组叠层石的形成机制。

Smart Grid and Renewable Energy 2022年第10期13卷 235-247页

Carbon monoxide can cause serious illness or even death if the functionality of smoke alarms fails in the residential home and, in fact, more than 350 persons die every year due to the leak of carbon monoxide. However, vulnerabilities and threats to smoke/CO alarms have not been well-studied. In this paper, through interconnect, a power replay attack has been studied in order to trigger a false alarm. The experimental results demonstrate the smoke alarm can be manipulated. This paper also concentrates on providing a sequence of security methods to defend the smoke alarm system. In future, how to protect smart detectors against attacks will be studied as this can force them to leave high-quality mode of operations.

The malicious activity comes in many forms, but many can come through trusted applications that we commonly use. Current systems have the capability to reduce damages, but implementations for the reduction are either outside of the system or are implemented in a manner that is unintuitive or confusing to users. In this paper, an access control method has been proposed that focuses on the alleviation of damage caused by such applications through the interactions between the user, application, and computer system. In details, the proposed model would work as a module or an interceptor to delegate permissions to applications through user input by using existing system calls. The evaluation about the proposed model as well as the first step implementation can show better security protection than existing systems.
