1森林水文服务市场的开发与经济激励机制——思考和启示显示文摘一、引言 在多数人看来,维护生态系统是社会的一项负担,他们忽略了这也是维持自然和人类生存的一项投资。例如,天然森林和湿地生态系统不仅能蓄积雨水和冰雪融水,然后使其逐步释放。Nels Johnson Andy White Danièle Perrot-Maitre 2002林业科技管理2002,,3:5

5Assessment of infectivity and the impact on neutralizing activity of immune sera of the COVID-19 variant,CAL.20C显示文摘Dear Editor,New variants of SARS-CoV-2 have been emerging since the initial outbreak in 2019;1 one of the latest ones was identified in Southern California in October 2020 and was subsequently detected in 26 other states in the United States as well as other countries as of January 2021.Zhongcheng Zhou Peng Du Meixing Yu Daniel T.Baptista-Hon Man Miao Andy P.Xiang Johnson Yiu-Nam Lau COVID-Immunity Investigation Group Gen Li Kang Zhang 2021Signal Transduction and Targeted Therapy2021,6,8:1

10Applicability of differential fluorescein diacetate and propidium iodide fluorescence staining for monitoring algal growth and viability显示文摘Microalgae can be cultivated for producing high-valued products through the production of enzymes to offset the cost of CO_(2) sequestration,providing financial incentives.The viability of algae in the photobioreactor needs to be monitored to ensure biologically active live cells.In this study,we explored a simple fluorometry method for differentiation of live and dead algal cells in photobioreactors by fluorescein diacetate(FDA)and propidium iodide(PI)fluorescence staining.FDA stains fluorescent green to the living cells while PI stains the dead cells,allowing the discrimination of live and dead cells.The method was evaluated using two green algae and two strains of cyanobacteria grown in shake flasks and a continuously stirred photobioreactor.The method was found applicable for Chlorella pyrenoidosa and Synechococcus 7002 but was not applicable for the cultures of Scenedesmus dimorphus and Synechococcus elongatus 7942.We conclude that FDA is a good stain for monitoring live algal cells in photobioreactors but its applicability to individual species of algae must be evaluated.Swati Yewalkar Tong Wu David Kuan Heli Wang Di Li Andy Johnson Dusko Posarac Sheldon Duff Xiaotao T.Bi 2019Waste Disposal and Sustainable Energy2019,1,3:0
11The SARS-CoV-2 spike L452R-E484Q variant in the Indian B.1.617 strain showed significant reduction in the neutralization activity of immune sera显示文摘To assess the impact of the key non-synonymous amino acid substitutions in the RBD of the spike protein of SARS-CoV-2 variant B.1.617.1(dominant variant identified in the current India outbreak)on the infectivity and neutralization activities of the immune sera,L452R and E484Q(L452R-E484Q variant),pseudotyped virus was constructed(with the D614G background).The impact on binding with the neutralizing antibodies was also assessed with an ELISA assay.Pseudotyped virus carrying a L452R-E484Q variant showed a comparable infectivity compared with D614G.However,there was a significant reduction in the neutralization activity of the immune sera from non-human primates vaccinated with a recombinant receptor binding domain(RBD)protein,convalescent patients,and healthy vaccinees vaccinated with anmRNA vaccine.In addition,there was a reduction in binding of L452R-E484Q-D614G protein to the antibodies of theimmune sera fromvaccinated nonhuman primates.These results highlight the interplay between infectivity and other biologic factors involved in the natural evolution of SARS-CoV-2.Reduced neutralization activities against the L452R-E484Q variant will have an impact on health authority planning and implications for the vaccination strategy/newvaccine development.Gen Li Zhongcheng Zhou Peng Du Meixing Yu Ning Li Xinxin Xiong Hong Huang Zhihai Liu Qinjin Dai Jie Zhu Chengbin Guo ShanyunWu Daniel T.Baptista-Hon Man Miao LamWai Ming Yong Wu Fanxin Zeng Charlotte L.Zhang Edward D.Zhang Haifeng Song Jianghai Liu Johnson Yiu-Nam Lau Andy P.Xiang Kang Zhang 2021Precision Clinical Medicine2021,4,3:0
12为何汽车制造商需要关注HTML5显示文摘不只是在汽车业,在平板电脑、尤其是智能手机等其他没备上,制造商们为了满足消费者对内容和服务的需求,纷纷部署了令人眼花缭乱的各种技术。HTML5是一项非专有且被普遍采用的标准,并在广泛的部署中证明了其价值所在。如果有什么能在现在和未来帮助汽车制造商在合理的成本条件下满足车载伉色、娱乐系统中的用户所需,那就非HTML5莫属了。Andy Gryc Kerry Johnson 2012世界电子元器件2012,,1:0
