| 1 | Molecular toxicity of earthworms induced by cadmium contaminated soil and biomarkers screening显示文摘Earthworms(Eisenia fetida) were used to study the impact of low-dose cadmium in treated artificial soil(0,0.6,3,6,15,30 mg/kg) and contaminated natural soil(1.46 mg/kg).The changes of earthworms' physiological related gene expressions of metallothionein(MT),annetocin,calreticulin and antimicrobial peptides were detected using real-time PCR after a 70-day incubation period.The results showed that low doses of cadmium could up regulate earthworms' MT and down regulate annetocin gene expression and show a significant positive and negative correlation respectively.The expression of two other genes,calreticulin and anti-microbial peptides,was induced at low doses of cadmium(highest gene expression at 0.6 mg/kg for calreticulin and 6 mg/kg for anti-microbial peptides) and inhibited at high doses.No significant correlation was found for these two genes.This study shows that MT and annetocin genes expression found in earthworms in contaminated soil have the potential to be developed as biomarkers of soil cadmium pollution. | Xiaohui Mo Yuhui Qiao Zhenjun Sun Xiaofei Sun Yang Li | 2012 | Journal of Environmental Sciences2012，24，8： | 4 |
| 3 | Genomic variation,origin tracing,and vaccine development of SARS-CoV-2:A systematic review显示文摘COVID-19 has spread globally to over 200 countries with more than 40 million confirmed cases and one million deaths as of November 1,2020.The SARS-CoV-2 virus,leading to COVID-19,shows extremely high rates of infectivity and replication,and can result in pneumonia,acute respiratory distress,or even mortality.SARS-CoV-2 has been found to continue to rapidly evolve,with several genomic variants emerging in different regions throughout the world.In addition,despite intensive study of the spike protein,its origin,and molecular mechanisms in mediating host invasion are still only partially resolved.Finally,the repertoire of drugs for COVID-19 treatment is still limited,with several candidates still under clinical trial and no effective therapeutic yet reported.Although vaccines based on either DNA/mRNA or protein have been deployed,their efficacy against emerging variants requires ongoing study,with multivalent vaccines supplanting the first-generation vaccines due to their low efficacy against new strains.Here,we provide a systematic review of studies on the epidemiology,immunological pathogenesis,molecular mechanisms,and structural biology,as well as approaches for drug or vaccine development for SARSCoV-2. | Tianbao Li Tao Huang Cheng Guo Ailan Wang Xiaoli Shi Xiaofei Mo Qingqing Lu Jing Sun Tingting Hui Geng Tian Leyi Wang Jialiang Yang | 2021 | The Innovation2021，2，2： | 1 |
