| 3 | Plant Metabolic Network 15:A resource of genome-wide metabolism databases for 126 plants and algae显示文摘To understand and engineer plant metabolism, we need a comprehensive and accurate annotation of all metabolic information across plant species. As a step towards this goal, we generated genome-scale metabolic pathway databases of 126 algal and plant genomes, ranging from model organisms to crops to medicinal plants(https://plantcyc.org).Of these, 104 have not been reported before.We systematically evaluated the quality of the databases, which revealed that our semi-automated validation pipeline dramatically improves the quality. We then compared the metabolic content across the 126 organisms using multiple correspondence analysis and found that Brassicaceae,Poaceae, and Chlorophyta appeared as metabolically distinct groups. To demonstrate the utility of this resource, we used recently published sorghum transcriptomics data to discover previously unreported trends of metabolism underlying drought tolerance. We also used single-cell transcriptomics data from the Arabidopsis root to infer cell typespecific metabolic pathways. This work shows the quality and quantity of our resource and demonstrates its wide-ranging utility in integrating metabolism with other areas of plant biology. | Charles Hawkins Daniel Ginzburg Kangmei Zhao William Dwyer Bo Xue Angela Xu Selena Rice Benjamin Cole Suzanne Paley Peter Karp Seung Y.Rhee | 2021 | Journal of Integrative Plant Biology2021，63，11： | 0 |
| 4 | Risk Factors for Severity and Mortality in Adult Patients Confirmed with COVID-19 in Sierra Leone: A Retrospective Study显示文摘Background:The coronavirus disease 2019(COVID-19)is a highly infectious respiratory disease.There is no recommended antiviral treatment approved for COVID-19 in Sierra Leone,and supportive care and protection of vital organ function are performed for the patients.This study summarized the clinical characteristics,drug treatments,and risk factors for the severity and prognosis of COVID-19 in Sierra Leone to provide evidence for the treatment of COVID-19.Methods:Data of 180 adult COVID-19 patients from the 34th Military Hospital in Freetown Sierra Leone between March 31,2020 and August 11,2020 were retrospectively collected.Patients with severe and critically ill are classified in the severe group,while patients that presented asymptomatic,mild,and moderate disease were grouped in the non-severe group.The clinical and laboratory information was retrospectively collected to assess the risk factors and treatment strategies for severe COVID-19.Demographic information,travel history,clinical symptoms and signs,laboratory detection results,chest examination findings,therapeutics,and clinical outcomes were collected from each case file.Multivariate logistic analysis was adopted to identify the risk factors for deaths.Additionally,the clinical efficacy of dexamethasone treatment was investigated.Results:Seventy-six(42.22%)cases were confirmed with severe COVID-19,while 104 patients(57.78%)were divided into the non-severe group.Fever(56.67%,102/180)and cough(50.00%,90/180)were the common symptoms of COVID-19.The death rate was 18.89%(34/180),and severe pneumonia(44.12%,15/34)and septic shock(23.53%,8/34)represented the leading reasons for deaths.The older age population,a combination of hypertension and diabetes,the presence of pneumonia,and high levels of inflammatory markers were significantly associated with severity of COVID-19 development(P<0.05 for all).Altered level of consciousness[odds ratio(OR)=56.574,95%confidence interval(CI)5.645–566.940,P=0.001],high levels of neutrophils(OR=1.341,95%CI 1.109–1.621,P=0.002)and C-reactive protein(CRP)(OR=1.014,95%CI 1.003–1.025,P=0.016)might be indicators for COVID-19 deaths.Dexamethasone treatment could reduce mortality[30.36%(17/56)vs.50.00%(10/20)]among severe COVID-19 cases,but the results were not statistically significant(P>0.05).Conclusions:The development and prognosis of COVID-19 may be significantly correlated with consciousness status,and the levels of neutrophils and CRP. | Bo Tu Sulaiman Lakoh Biao Xu Marta Lado Reginald Cole Fang Chu Susan Hastings-Spaine Mohamed Bole Jalloh Junjie Zheng Weiwei Chen Stephen Sevalie | 2022 | Infectious Diseases & Immunity2022，2，2： | 0 |
