摘要： It has been reported that the host of SARS-CoV-2 can be extremely wide due to the conservation of angiotensin converting enzyme 2 in mammals[1].Several studies have reported natural or experimental infection with SARS-CoV-2 in pets,farm and captive wild animals[2-4].However,to the best of our knowledge,there was no published study assessing virus circulation among domestic or captive animals in Central,West and East Africa.In this study,we assessed the presence and circulation of SARS-CoV-2 or other betacoronaviruses in pets,livestock and animals kept in captivity in conservation centers in Haut-Ogoouéprovince,southeastern Gabon.

摘要： The 19th Central Committee of the Communist Party of China convened its sixth plenary session in Beijing from November 8 to 11,2021.At the session,the Central Committee considered and adopted the Resolution on the Major Achievements and Historical Experience of the Party.The resolution pooled the wisdom of the whole party,made comprehensive and systematic summary of the major achievements and histoncal experience of the Party,and laid emphasis on the illustration of the historic achievements and historic shifts in the cause of the Party and the country since the Party's 18^(th) National Congress.Let's take a look!

摘要： The central nervous system is known to have limited regenerative capacity.Not only does this halt the human body’s reparative processes after central nervous system lesions,but it also impedes the establishment of effective and safe therapeutic options for such patients.Despite the high prevalence of stroke and spinal cord injury in the general population,these conditions remain incurable and place a heavy burden on patients’families and on society more broadly.Neuroregeneration and neural engineering are diverse biomedical fields that attempt reparative treatments,utilizing stem cells-based strategies,biologically active molecules,nanotechnology,exosomes and highly tunable biodegradable systems(e.g.,certain hydrogels).Although there are studies demonstrating promising preclinical results,safe clinical translation has not yet been accomplished.A key gap in clinical translation is the absence of an ideal animal or ex vivo model that can perfectly simulate the human microenvironment,and also correspond to all the complex pathophysiological and neuroanatomical factors that affect functional outcomes in humans after central nervous system injury.Such an ideal model does not currently exist,but it seems that the nonhuman primate model is uniquely qualified for this role,given its close resemblance to humans.This review considers some regenerative therapies for central nervous system repair that hold promise for future clinical translation.In addition,it attempts to uncover some of the main reasons why clinical translation might fail without the implementation of nonhuman primate models in the research pipeline.

摘要： BACKGROUND Listeria monocytogenes (L. monocytogenes), a Gram-positive facultatively intracellular bacterium, is the causative agent of human listeriosis. Listeria infection is usually found in immunocompromised patients, including elderly people, pregnant women, and newborns, whereas it is rare in healthy people. L. monocytogenes may cause meningitis, meningoencephalitis, and some very rare and severe complications, such as hydrocephalus and intracranial hemorrhage, which cause high mortality and morbidity worldwide. Up to now, reports on hydrocephalus and intracranial hemorrhage due to L. monocytogenes are few. CASE SUMMARY We herein report a case of rhombencephalitis caused by L. monocytogenes in a 29- year-old man. He was admitted to the hospital with a 2-d history of headache and fever. He consumed unpasteurized cooked beef two days before appearance. His medical history included type 2 diabetes mellitus, and contaminated beef intake 2 d before onset. Cerebrospinal fluid analysis revealed Gram-positive rod infection, and blood culture was positive for L. monocytogenes. Magnetic resonance imaging findings suggested rhombencephalitis and hydrocephalus. Treatment was started empirically and then modified according to the blood culture results. Repeated CT images were suggestive of intracranial hemorrhage. Although the patient underwent aggressive external ventricular drainage, he died of a continuing deterioration of intracranial conditions.CONCLUSION Hydrocephalus, intracranial hemorrhage, and inappropriate antimicrobial treatment are the determinations of unfavorable outcomes.

摘要： 本发明提供一种在图数据库更新时快速计算Betweenness Centrality的方法。所述在图数据库更新时快速计算Betweenness Centrality的方法，包括以下操作步骤：S1、寻找原始图中的最大联合环MUC；S2、当图更新(增边、删边)时，开始更新图中的最大联合环MUC。本发明提供一种在图数据库更新时快速计算Betweenness Centrality的方法，相较于现有的算法，本方法在思路上充分利用了图更新时，Betweenness Centrality发生改变的部分(各个MUC集合)、不发生改变的部分，图更新时仅仅用昂贵的Brandes算法计算各个MUC集合内顶点的局部Betweenness Centrality，在此基础上，对于还没考虑到的顶点对使用简单的附加计算，就能得出MUC中各顶点精确(全局)Betweenness Centrality，从而缩小了昂贵的重新计算Betweenness Centrality大小的顶点数量与范围，从而加快了计算时间。
