1Anti-fungal and anti-bacterial activities of ethanol extracts of selected traditional Chinese medicinal herbs显示文摘Objective:To evaluate in ritro antimicrobial activities of selected 58 ethno-medicinal plant extracts with a view to assess their therapeutic potential.Methods:A total of 58 traditional Chinese medicinal plants were carefully selected based on the literature review and their traditional use.The antimicrobial activities of ethanol extracts of these medicinal plants were tested against fungi(Aspergillus funigaius),yeast(Candida albicans),gram-negative(Acirelobacter haumannii and Pseudornnruis aeruginosa)and gram-positive bacteria(Staphglococcus aureus).The activities were tested at three different concentrations of 1.00,0.10 and 0.01 mg/mL.The data was analysed using Gene data Screener program.Results:The measured antimicrobial activities indicated that out of the 58 plant extracts,15 extracts showed anti-fungal activity and 23 extracts exhibited anti-bacterial activity.Eight plant extracts have exhibited both anti-bacterial and anti-fungal activities.For instance,Eucommia ulmoides,Pohgonum cuspidcrtum,Poria cocas and Uncaria rhineophylla showed activity against both bacterial and fungal strains,indicating their broad spectrum of activity.Conclusions:The results revealed that the ethanol extracts of 30 plants out of the selected 58 possess significant antimicrobial activities.It is interesting to note that the findings from the current study are consistent with the traditional use.A clear correlation has also been found between the antimicrobial activity and the flavonoid content of the plant extracts which is in agreement with the literature.Hence.the results presented here can be used to guide the selection of potential plant species for the isolation and structure elucidation of novel antimicrobial compounds in order to establish the structure-activity relationship.This in turn is expected to lead the way to the discovery of novel antimicrobial agents for therapeutic use.Lin Zhang Anjaneya S.Ravipati Sundar R Koyyalamudi Sang Chul Jeong Narsimha Reddy John Bartlett Paul T.Smith Mercedes de la Cruz Maria Cndida Monteiro ngeles Melguizo Ester Jimnez Francisca Vicente 2013Asian Pacific Journal of Tropical Medicine2013,6,9:23
2Platelet thromboxane(11-dehydro-Thromboxane B_2) and aspirin response in patients with diabetes and coronary artery disease显示文摘Aspirin(ASA) irreversibly inhibits platelet cyclooxygenase-1(COX-1) leading to decreased thromboxane-mediated platelet activation. The effect of ASA ingestion on thromboxane generation was evaluated in patients with diabetes(DM) and cardiovascular disease. Thromboxane inhibition was assessed by measuring the urinary excretion of 11-dehydro-thromboxane B2(11dhTxB2), a stable metabolite of thromboxane A2. The mean baseline urinary 11dhTxB2 of DM was 69.6% higher than healthy controls(P = 0.024): female subjects(DM and controls) had 50.9% higher baseline 11dhTxB2 than males(P = 0.0004), while age or disease duration had no influence. Daily ASA ingestion inhibited urinary 11dhTxB2 in both DM(71.7%) and controls(75.1%, P < 0.0001). Using a pre-established cut-off of 1500 pg/mg of urinary 11dhTxB2, there were twice as many ASA poor responders(ASA 'resistant') in DM than in controls(14.8% and 8.4%, respectively). The rate of ASA poor responders in two populations of acute coronary syndrome(ACS) patients was 28.6 and 28.7%, in spite of a significant(81.6%) inhibition of urinary 11dhTxB2(P < 0.0001). Both baseline 11dhTxB2 levels and rate of poor ASA responders were significantly higher in DM and ACS compared to controls. Underlying systemic oxidative inflammation may maintain platelet function in atherosclerotic cardiovascular disease irrespective of COX-1 pathway inhibition and/or increase systemic generation of thromboxane from non-platelet sources.Luis R Lopez Kirk E Guyer Ignacio Garcia De La Torre Kelly R Pitts Eiji Matsuura Paul RJ Ames 2014World Journal of Diabetes2014,5,2:13

14Revealing CO_(2)-Fixing SAR11 Bacteria in the Ocean by Raman-Based Single-Cell Metabolic Profiling and Genomics显示文摘The majority of marine microbes remain uncultured,which hinders the identification and mining of CO_(2)-fixing genes,pathways,and chassis from the oceans.Here,we investigated CO_(2)-fixing microbes in seawater from the euphotic zone of the Yellow Sea of China by detecting and tracking their ^(13)C-bicarbonate(^(13)C-HCO_(3)^(-))intake via single-cell Raman spectra(SCRS)analysis.The target cells were then isolated by Raman-activated Gravity-driven Encapsulation(RAGE),and their genomes were amplified and sequenced at one-cell resolution.The single-cell metabolism,phenotype and genome are consistent.We identified a notyet-cultured Pelagibacter spp.,which actively assimilates ^(13)C-HCO_(3)^(-),and also possesses most of the genes encoding enzymes of the Calvin-Benson cycle for CO_(2) fixation,a complete gene set for a rhodopsin-based light-harvesting system,and the full genes necessary for carotenoid synthesis.The four proteorhodopsin(PR)genes identified in the Pelagibacter spp.were confirmed by heterologous expression in E.coli.These results suggest that hitherto uncultured Pelagibacter spp.uses light-powered metabolism to contribute to global carbon cycling.Xiaoyan Jing Yanhai Gong Teng Xu Paul ADavison Craig MacGregor-Chatwin CNeil Hunter La Xu Yu Meng Yuetong Ji Bo Ma Jian Xu Wei E.Huang 2022BioDesign Research2022,,1:1
