The aim of our study was to use a biosurfactant produced by Bacillus and Lactobacillus isolates as an antiseptic in the formulation of local soap. A total of 60 isolates were characterized by microbiological techniques (30 Bacillus and 30 Lactobacillus) and the ability to produce biosurfactants was demonstrated by a hydrocarbon emulsification index (E24). The emulsification indexes (E24) varied from 9% to 100% for Bacillus and from 33% to 100% for Lactobacillus as well. The antagonistic assay showed that biosurfactants were able to inhibit the formation of biofilms and growth of pathogens such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus cereus, Salmonella typhirium, Shigella boydii and Proteus mirabilis. The biosurfactant consortium (BioC) from Bacillus consortium and from Lactobacillus was able to inhibit biofilm formation and the pathogens growth. The BioC was stable to alkaline pH and the temperatures stability of Biosurfactant was ranging from 50°C to 90°C. The soap was made by the cold saponification process using one biosurfactant consortium formulated. This soap has a pH of 10 and showed good cleaning power and good foam stability. Similarly, the soap showed good antiseptic power and disinfection power against all pathogens tested. Handwashing is critical to preventing disease transmission. The persistence of pathogens in waste water was evaluated. The BioS produced showed good disinfection power against all pathogens tested. The valor of reduction on the hands and in the waste water was significantly more than compared to the control soaps used. This soap could be used in the prevention, fighting, and treatment of bacterial and viral infections.

考虑到多智能体系统在复杂环境中受到外部干扰和控制器受到恶意攻击等问题,本文旨在研究一类受扰非线性多智能体系统在事件触发机制和脉冲控制下的领导跟随拟一致性。不同于现有文献中需要事先指定最小事件触发间隔,本文所设计的动态事件触发机制通过其参数的选择加以保证,从而避免了芝诺行为的发生。基于此机制,进一步给出了系统实现拟一致性的一些充分条件以及相应误差上界的估量值。最后,通过数值仿真例子验证了结果的有效性。

Meta-Analysis Study of the Effects of Yeast Probiotic Supplementation on Milk Production and Energy Corrected Milk of Lactating Dairy Cows

引用

Agricultural Sciences 2023年第9期14卷 1179-1192页

作者： Nizar Salah Héloïse Legendre Pauline Peltier Pain Clara Berger Valentin Nenov Francois Machuron Maxime Briche Phileo by Lesaffre Marcq-en-Baroeul France Lesaffre International Marcq-en-Baroeul France

The aim of this study was to use a meta-analytic approach to evaluate the effect of commercially available yeast probiotic “Actisaf® Sc 47” (Saccharomyces cerevisiae CNCM I-4407) produced and marketed by Phileo by Lesaffre on milk performance in dairy cows. Data from 22 trials including 17 with parallel designs and 5 with cross-over designs were collected, and only data with parallel designs were analyzed. From those trials, 4 are published and 13 are from technical reports. In total, 34 comparisons and 1074 dairy cows met the criteria for inclusion in the final analysis of milk yield (MY). For energy corrected milk (ECM), six trials with 12 comparisons and 476 dairy cows met the criteria for inclusion in the final analysis. Because the data are from different trials with different conditions, the statistical model defined includes the fixed effect of the treatment (with vs. without Actisaf® Sc 47) and the random effect of the trial. The meta-analysis showed a moderate heterogeneity for MY and ECM. The random effect meta-analysis showed an estimated mean difference +1.72 kg/d [95% confidence interval (CI): 1.01 to 2.44] and +2.45 kg/d (95% CI: 1.73 to 3.17) for MY and ECM respectively, in favour of Actisaf® Sc 47. The analysis of data without trials conducted under heat stress conditions showed positive effect of Actisaf® Sc 47. The random effect meta-analysis showed an estimated mean difference of +1.69 kg/d [95% CI: 1.24 to 2.14] and +2.92 kg/d (95% CI: 2.45 to 3.40) for MY and ECM respectively, in favour of Actisaf® Sc 47. These observations provide strong evidence that this commercially available yeast probiotic can significantly improve milk performances of dairy cows under different conditions.

目的本研究分析了2型糖尿病(T2DM)患者超声检测的颈总动脉内中膜厚度(cIMT)及其与年龄的关系,并关联了cIMT与握力、步速之间的联系。方法来自英国生物银行(UKB)2014年的横断面数据,共纳人1036名cIMT数据完整的T2DM患者,从4个角度采集cIMT数据(右颈总动脉:120150%;左颈总动脉:210°、240°),每个测量角度产生3个指标(最大值、平均值和最小值),合计12个cIMT指标。分析其在增龄和性别间的变化趋势;评估12个cIMT指标中用于筛选颈动脉异常组(包括增厚和斑块组,cIMT1000μm)阳性率最高的单个指标;按该指标三分位分组并评估组间握力和步速及血压间的差异。结果所有12个cIMT指标均随年龄增加而增厚(P<0.001),男性T2DM患者的左侧颈总动脉的所有cIMT指标均高于女性,其中,240℃IMT的最大值、平均值和最小值在男女间的差异均随增龄而继续增加;按240℃IMT的最大值用于评估颈动脉异常组时,男女中的阳性率均高于其他11个指标,且男女间还存在显著性差异(χ^(2)=24.391,P<0.001);按左侧240℃IMT的最大值进行三分位分组,经年龄性别匹配后,发现各组间该指标增加握力和步速均下降。丝结论在T2DM患者中,cIMT随年龄增长而上升,尤其左侧240℃IMT在男性显著高于女性,且其与握力及步速下降密切相关,强调了在超声检查中关注此指标的重要性,对评估老年患者身体功能具有重要意义。
