1培养条件及表面活性剂的添加对纳豆芽孢杆菌生物膜形成的影响显示文摘采用改良的微孔板法培养纳豆芽孢杆菌(Bacillus subtilis natto),通过结晶紫染色定量分析产生的生物膜。结果表明:培养条件为pH 7、温度37℃、培养72 h且在5 g/100 mL葡萄糖-5 g/100 mL NaCl条件下成膜能力最佳。柠檬酸二铵和聚乙二醇-200(polyethylene glycol-200,PEG-200)随着质量浓度的增加对生物膜的形成量呈现先下降后上升的趋势,十二烷基磺酸钠(sodium dodecyl sulfate,SDS)抑制生物膜的形成,十六烷基三甲基溴化铵(cetyl trimethyl ammonium bromide,CTAB)促进生物膜的形成。所以低温抑制生物膜的形成,一定浓度的NaCl和葡萄糖促进生物膜形成,不同的表面活性剂对其生物膜的影响机制不同,为纳豆芽孢杆菌生物膜的研究提供理论基础。冯静静 杨自名 吴静 李伟 Sokhna Mbacke Gningue 赵礼军 周文豪 薛正莲 王洲 刘艳 2020食品与发酵工业2020,46,3:7
2不同培养条件对枯草芽胞杆菌BS168-ΔsinR生物膜形成及维生素K2产量的影响显示文摘枯草芽胞杆菌(Bacillus subtilis)是合成维生素K2的微生物之一,维生素K2的合成量又与细菌生物膜有重要关系。其中sinR是生物膜形成环节中的关键调节基因,我们用同源重组的方法构建枯草芽胞杆菌sinR缺失突变体(ΔsinR)菌株,再以BS168-ΔsinR菌株为出发菌株,采用微孔板法-结晶紫染色测定生物膜形成量,核酸定量仪测定胞外蛋白,苯酚硫酸法测定胞外多糖,HPLC测定维生素K2的生物合成量。比较分析了不同温度、pH、以及不同浓度的金属离子(Mn^(2+)、 Fe^(2+)、Ca^(2+))对枯草芽胞杆菌BS168及BS168-ΔsinR生物膜形成能力以及维生素K2合成量的影响。结果表明,重组菌BS168-ΔsinR生物膜形成能力和维生素K2合成能力均优于原始菌BS168,且重组菌在生物膜形成、维生素K2合成过程中对温度、酸碱性的适应能力也强于原始菌。一定浓度的金属离子可以促进生物膜的形成及维生素K2的合成。2株菌生物膜形成的最佳条件为温度37~40℃、pH 8.0、Mn^(2+)浓度0.01 mmol/L、 Fe^(2+)浓度1μmol/L、Ca^(2+)浓度0.01 mmol/L,维生素K2合成的最佳条件是温度40℃、pH 7.0~8.0、Mn^(2+)浓度0.1 mmol/L、 Fe^(2+)浓度50μmol/L、Ca^(2+)浓度1 mmol/L。该研究为深入探究sinR基因参与枯草芽胞杆菌生物膜形成的机制及提高维生素K2合成产量提供实验基础和理论支撑。吴静 李伟 冯静静 周梦洁 胡汶松 汪剑 SOKHNA MBACKE Gningue 吴佳雯 赵礼军 徐文瀚 薛正莲 王洲 刘艳 2021食品与发酵工业2021,47,14:4
3The paradigm of protein acetylation in Parkinson's disease显示文摘Acetylation is a post-translational modification that is regulated by two antagonistic enzymes,histone acetyltransferases(HATs)and histone deacetylases(HDACs).HATs transfer the acetyl group from acetyl-CoA to lysine residues of proteins while HDACs remove it(Yakhine-Diop et al.,2018b).The impairment of HAT or HDAC activity elicits changes in the protein acetylation status which disturb several cellular processes,among others,gene expression,autophagy etc.,leading finally to cell death.Both enzymes are associated with Parkinson’s disease(PD)pathogenesis.In dopaminergic cells,neurotoxins provoke apoptotic cell death by increasing histone acetylation levels.While paraquat(Song et al.,2011)and rotenone(Feng et al.,2015)reduce HDAC activity,dieldrin(Song et al.,2010)enhances HAT activity.However in vivo,paraquat-induced upregulation ofα-synuclein triggers histone hypoacetylation.Sokhna M.S.Yakhine-Diop Guadalupe Martínez-Chacón Elisabet Uribe-Carretero Mireia Niso-Santano Rosa A.González-Polo José M.Fuentes 2019Neural Regeneration Research2019,14,6:2

8Prevalence of diarrhoea and risk factors among children under five years old in Mbour,Senegal:a cross-sectional study显示文摘Background:Diarrhoeal diseases remain an important cause of mortality and morbidity among children,particularly in low-and middle-income countries.In Senegal,diarrhoea is responsible for 15%of all deaths in children under the age of five and is the third leading cause of childhood deaths.For targeted planning and implementation of prevention strategies,a context-specific understanding of the determinants of diarrhoeal diseases is needed.The aim of this study was to identify risk factors of diarrhoeal diseases in children under the age of five in Mbour,Senegal.Methods:Between February and March 2014,a cross-sectional survey was conducted in four zones of Mbour to estimate the burden of diarrhoeal diseases(i.e.diarrhoea episodes in the 2 weeks preceding the survey)and associated risk factors.The zones covered urban central,peri-central,north peripheral and south peripheral areas.Overall,596 households were surveyed by a questionnaire,yielding information on sociodemographic,environmental and hygiene behavioural factors.Univariable and multivariable logistic regression analyses were used to identify risk factors associated with the occurrence of diarrhoea.Results:The reported prevalence of diarrhoea among children under the age of five during the 2 weeks preceding the survey was 26%.Without adjustment,the highest diarrhoea prevalence rates were observed in the peri-central(44.8%)and urban central zones(36.3%).Multivariable regression revealed significant associations between diarrhoeal diseases and unemployment of mothers(adjusted odds ratio[aOR]=1.62,95%confidence interval[CI]:1.18-2.23),use of open bags for storing household waste(aOR=1.75,95%CI:1.00-3.02),evacuation of household waste in public streets(aOR=2.07,95%CI:1.20-3.55),no treatment of stored drinking water(aOR=1.69,95%CI:1.11-2.56)and use of shared toilets(aOR=1.69,95%CI:1.11-2.56).Conclusion:We found a high prevalence of diarrhoea in children under the age of five in Mbour,with the highest prevalence occurring in the central and peri-central areas.These findings underscore the need for public health interventions to alleviate the burden of diarrhoea among vulnerable groups.Promotion of solid waste disposal and reduction of wastewater exposure should be implemented without delay.Sokhna Thiam Aminata N.Diene Samuel Fuhrimann Mirko S.Winkler Ibrahima Sy Jacques A.Ndione Christian Schindler Penelope Vounatsou Jurg Utzinger Ousmane Faye Gueladio Cisse 2017Infectious Diseases of Poverty2017,6,1:1

10The dual role of necrostatin-1 in Parkinson’s disease models显示文摘Neuronal cell death is the main hallmark of Parkinson’s disease(PD).It is an irreversible process promoted by neurotoxins and/or genetic mutations.Different types of cell death have been associated with PD.The mechanisms by which neurons decide to specific type of cell death remain elusive.However,it is well known that cell death can be either programmed or not.Apoptosis is a programmed cell death that involves the release of cytochrome c from damaged mitochondria to cytosol and the activation of caspases leading to nuclear condensation.Necrosis is a caspase-independent cell death characterized by a gain in cell volume,rupture of plasma membrane and leak of cell contents,inflammation,and affects neighbouring cells.It was classified as a nonprogrammed cell death,but there are types of necrotic death triggered by a protein activation cascade,including necroptosis.Eva Alegre-Cortes Guadalupe Martinez-Chacon Jose M.Fuentes Sokhna M.S.Yakhine-Diop 2021Neural Regeneration Research2021,16,10:0
