| 1 | Biogenesis of antibacterial silver nanoparticles using the endophytic bacterium Bacillus cereus isolated from Garcinia xanthochymus显示文摘Objective:To synthesize the ecofriendly nanoparticles,which is viewed as an alternative to the chemical method which initiated the use of microbes like bacteria and fungi in their synthesis.Methods:The current study uses the endophytic bacterium Bacillus cereus isolated from the Garcinia xanthochymus to synthesize the silver nanoparticles(AgNPs).The AgNPs were synthesized by reduction of silver nitrate solution by the endophytic bacterium after incubation for 3-5 d at room temperature.The synthesis was initially observed by colour change from pale white to brown which was confirmed by UV-Vis spectroscopy.The AgNPs were further characterized using FTIR,SEM-EDX and TEM analyses.Results:The synthesized nanoparticles were found to he spherical with the size in the range of 20-40 nm which showed a slight aggregation.The energy-dispersive spectra of the nanoparticle dispersion confirmed the presence of elemental silver.The AgNPs were found to have antibacterial activity against a few pathogenic bacteria like Escherichia coli,Pseudomonas aeruginosa,Staphylococcus aureus,Salmonella typhi and Klebsiella pneumoniae.Conclusions:The endophytic bacteria identified as Bacillus cereus was able to synthesize silver nanoparticles with potential antibacterial activity. | Swetha Sunkar C Valli Nachiyar | 2012 | Asian Pacific Journal of Tropical Biomedicine2012,2,12: | 5 |

| 12 | In-hospital mortality of hepatorenal syndrome in the United States:Nationwide inpatient sample显示文摘BACKGROUND Hepatorenal syndrome(HRS)is a life-threatening condition among patients with advanced liver disease.Data trends specific to hospital mortality and hospital admission resource utilization for HRS remain limited.AIM To assess the temporal trend in mortality and identify the predictors for mortality among hospital admissions for HRS in the United States.METHODS We used the National Inpatient Sample database to identify an unweighted sample of 4938 hospital admissions for HRS from 2005 to 2014(weighted sample of 23973 admissions).The primary outcomes were temporal trends in mortality as well as predictors for hospital mortality.We estimated odds ratios from multilevel mixed effect logistic regression to identify patient characteristics and treatments associated with hospital mortality.RESULTS Overall hospital mortality was 32%.Hospital mortality decreased from 44%in 2005 to 24%in 2014(P<0.001),while there was an increase in the rate of liver transplantation(P=0.02),renal replacement therapy(P<0.001),length of hospital stay(P<0.001),and hospitalization cost(P<0.001).On multivariable analysis,older age,alcohol use,coagulopathy,neurological disorder,and need for mechanical ventilation predicted higher hospital mortality,whereas liver transplantation,transjugular intrahepatic portosystemic shunt,and abdominal paracentesis were associated with lower hospital mortality.CONCLUSION Although there was an increase in resource utilizations,hospital mortality among patients admitted for HRS significantly improved.Several predictors for hospital mortality were identified. | Wisit Kaewput Charat Thongprayoon Carissa Y Dumancas Swetha R Kanduri Karthik Kovvuru Chalermrat Kaewput Pattharawin Pattharanitima Tananchai Petnak Ploypin Lertjitbanjong Boonphiphop Boonpheng Karn Wijarnpreecha Jose L Zabala Genovez Saraschandra Vallabhajosyula Caroline C Jadlowiec Fawad Qureshi Wisit Cheungpasitporn | 2021 | World Journal of Gastroenterology2021,27,45: | 0 |
