1Animals as sources of food-borne pathogens: A review显示文摘Food-producing animals are the major reservoirs for many foodborne pathogens such as Campylobacter species, non-Typhi serotypes of Salmonella enterica, Shiga toxin-producing strains of Escherichia coli, and Listeria monocytogenes. The zoonotic potential of foodborne pathogens and their ability to produce toxins causing diseases or even death are sufficient to recognize the seriousness of the situation. This manuscript reviews the evidence that links animals as vehicles of the foodborne pathogens Salmonella,Campylobacter, Shiga toxigenic E. coli, and L. monocytogenes, their impact, and their current status. We conclude that these pathogenic bacteria will continue causing outbreaks and deaths throughout the world, because no effective interventions have eliminated them from animals and food.Norma Heredia Santos García 2018Animal Nutrition2018,,3:14
2Stem cell therapy in the management of shoulder rotator cuff disorders显示文摘Rotator cuff tears are frequent shoulder problems that are usually dealt with surgical repair. Despite improved surgical techniques, the tendon-to-bone healing rate is unsatisfactory due to difficulties in restoring the delicate transitional tissue between bone and tendon. It is essential to understand the molecular mechanisms that determine this failure. The study of the molecular environment during embryogenesis and during normal healing after injury is key in devising strategies to get a successful repair. Mesenchymal stem cells(MSC) can differentiate into different mesodermal tissues and have a strong paracrine, anti-inflammatory, immunoregulatory and angiogenic potential. Stem cell therapy is thus a potentially effective therapy to enhance rotator cuff healing. Promising results have been reported with the use of autologous MSC of different origins in animal studies: they have shown to have better healing properties, increasing the amount of fibrocartilage formation and improving the orientation of fibrocartilage fibers with less immunologic response and reduced lymphocyte infiltration. All these changes lead to an increase in biomechanical strength. However, animal research is still inconclusive and more experimental studies are needed before human application. Future directions include expanded stem cell therapy in combination with growth factors or different scaffolds as well as new stem cell types and gene therapy.Maria Valencia Mora Miguel A Ruiz Ibán Jorge Díaz Heredia Raul Barco Laakso Ricardo Cuéllar Mariano García Arranz 2015World Journal of Stem Cells2015,7,4:6
3高热致胚胎发育毒性机理的研究——热休克蛋白合成显示文摘按Kimmel实验条件热暴露孕10天大鼠。暴露后2小时取胚胎用^(35)S—蛋氨酸标记,SDS—PAGE蛋白分析,可见70和90KilodaltonKD热休克蛋白合成增加。70KD HSP合成用Westernblot分析又进一步得到证实。离体培养胚胎热暴露后,用同样方法分析蛋白,证实70和90KD HSPs合成增加。结果与Kimmel骨骼畸形和胚胎体节融合发生率相符合。本结果为German提出的环境致畸机理假说提供了依据。芦春林 C A Kimmel G L Kimmel D J Heredia B R Fisher N T Brown 1993北京医科大学学报1993,25,6:4
4A PD-Type State-Dependent Riccati Equation With Iterative Learning Augmentation for Mechanical Systems显示文摘This work proposes a novel proportional-derivative(PD)-type state-dependent Riccati equation(SDRE)approach with iterative learning control(ILC)augmentation.On the one hand,the PD-type control gains could adopt many useful available criteria and tools of conventional PD controllers.On the other hand,the SDRE adds nonlinear and optimality characteristics to the controller,i.e.,increasing the stability margins.These advantages with the ILC correction part deliver a precise control law with the capability of error reduction by learning.The SDRE provides a symmetric-positive-definite distributed nonlinear suboptimal gain K(x)for the control input law u=–R–1(x)BT(x)K(x)x.The sub-blocks of the overall gain R–1(x)BT(x)K(x),are not necessarily symmetric positive definite.A new design is proposed to transform the optimal gain into two symmetric-positive-definite gains like PD-type controllers as u=–KSP(x)e–KSD(x)?.The new form allows us to analytically prove the stability of the proposed learning-based controller for mechanical systems;and presents guaranteed uniform boundedness in finite-time between learning loops.The symmetric PD-type controller is also developed for the state-dependent differential Riccati equation(SDDRE)to manipulate the final time.The SDDRE expresses a differential equation with a final boundary condition,which imposes a constraint on time that could be used for finitetime control.So,the availability of PD-type finite-time control is an asset for enhancing the conventional classical linear controllers with this tool.The learning rules benefit from the gradient descent method for both regulation and tracking cases.One of the advantages of this approach is a guaranteed-stability even from the first loop of learning.A mechanical manipulator,as an illustrative example,was simulated for both regulation and tracking problems.Successful experimental validation was done to show the capability of the system in practice by the implementation of the proposed method on a variable-pitch rotor benchmark.Saeed Rafee Nekoo JoséÁngel Acosta Guillermo Heredia Anibal Ollero 2022IEEE/CAA Journal of Automatica Sinica2022,9,8:2
