| 2 | Effects of Glomus mosseae on the toxicity of heavy metals to Vicia faba显示文摘A glasshouse pot experiment was conducted to investigate effects of th e arbuscular mycorrhizal fungus Glomus mosseae on the growth of Vicia faba and t oxicity induced by heavy metals (HMs) (Cu, Zn, Pb and Cd) in a field soil contam inated by a mixture of these metals. There was also uninoculation treatment (NM) simultaneously. Mycorrhizal (GM) plants have significantly increased growth and tolerance to toxicity induced by heavy metals compared with NM plants. P uptake was significantly increased in GM plants. Mycorrhizal symbiosis reduced the tra nsportation of HMs from root to shoot by immobilizing HMs in the mycorrhizal, sh own by increasing the ratios of HMs from root to shoot. Oxidative stress, which can induce DNA damage, is an important mechanism of heavy metal toxicity. GM tre atment decreased oxidative stress by intricating antioxidative systems such as p eroxidases and non-enzymic systems including soluble protein. The DNA damage ind uced by heavy metals was detected using comet assay, which showed DNA damage in the plants was decreased by the GM treatment. | ZHANG Xu-hong LIN Ai-jun CHEN Bao-dong WANG You-shan SMITH Sally E SMITH F Andrew | 2006 | Journal of Environmental Sciences2006，18，4： | 10 |

| 6 | Association of latitude and altitude with adverse outcomes in patients with COVID-19: The VIRUS registry显示文摘BACKGROUND The coronavirus disease 2019(COVID-19)course may be affected by environmental factors.Ecological studies previously suggested a link between climatological factors and COVID-19 fatality rates.However,individual-level impact of these factors has not been thoroughly evaluated yet.AIM To study the association of climatological factors related to patient location with unfavorable outcomes in patients.METHODS In this observational analysis of the Society of Critical Care Medicine Discovery Viral Infection and Respiratory Illness Universal Study:COVID-19 Registry cohort,the latitudes and altitudes of hospitals were examined as a covariate for mortality within 28 d of admission and the length of hospital stay.Adjusting for baseline parameters and admission date,multivariable regression modeling was utilized.Generalized estimating equations were used to fit the models.RESULTS Twenty-two thousand one hundred eight patients from over 20 countries were evaluated.The median age was 62(interquartile range:49-74)years,and 54%of the included patients were males.The median age increased with increasing latitude as well as the frequency of comorbidities.Contrarily,the percentage of comorbidities was lower in elevated altitudes.Mortality within 28 d of hospital admission was found to be 25%.The median hospital-free days among all included patients was 20 d.Despite the significant linear relationship between mortality and hospital-free days(adjusted odds ratio(aOR)=1.39(1.04,1.86),P=0.025 for mortality within 28 d of admission;aOR=-1.47(-2.60,-0.33),P=0.011 for hospital-free days),suggesting that adverse patient outcomes were more common in locations further away from the Equator;the results were no longer significant when adjusted for baseline differences(aOR=1.32(1.00,1.74),P=0.051 for 28-day mortality;aOR=-1.07(-2.13,-0.01),P=0.050 for hospital-free days).When we looked at the altitude’s effect,we discovered that it demonstrated a non-linear association with mortality within 28 d of hospital admission(aOR=0.96(0.62,1.47),1.04(0.92,1.19),0.49(0.22,0.90),and 0.51(0.27,0.98),for the altitude points of 75 MASL,125 MASL,400 MASL,and 600 MASL,in comparison to the reference altitude of 148 m.a.s.l,respectively.P=0.001).We detected an association between latitude and 28-day mortality as well as hospital-free days in this worldwide study.When the baseline features were taken into account,however,this did not stay significant.CONCLUSION Our findings suggest that differences observed in previous epidemiological studies may be due to ecological fallacy rather than implying a causal relationship at the patient level. | Aysun Tekin Shahraz Qamar Romil Singh Vikas Bansal Mayank Sharma Allison M LeMahieu Andrew C Hanson Phillip J Schulte Marija Bogojevic Neha Deo Simon Zec Diana J Valencia Morales Katherine A Belden Smith F Heavner Margit Kaufman Sreekanth Cheruku Valerie C Danesh Valerie M Banner-Goodspeed Catherine A St Hill Amy B Christie Syed A Khan Lynn Retford Karen Boman Vishakha KKumar John C O'Horo Juan Pablo Domecq Allan J Walkey Ognjen Gajic Rahul Kashyap Salim Surani TheSociety of Critical Care Medicine(SCCM)Discovery Viral Infection and Respiratory Illness Universal Study(VIRUS):COVID-Registry Investigator Group | 2022 | World Journal of Critical Care Medicine2022，11，2： | 0 |
