1纳米结构膜的制备及其在导电聚合物电化学聚合中的应用显示文摘导电聚合物涂层的表面粗糙度和表面积对神经元传感器电极的敏感性和生物相容性有着重要的影响,利用纳米多孔膜材料进行电化学模板聚合是获得高粗糙度和高表面积的导电聚合物涂层的理想途径。利用聚苯乙烯(PS)、聚甲醛丙烯酸甲酯(PMMA)两者的紫外光辐照特性不同,研究了用紫外光辐照光刻法制备聚苯乙烯-甲基丙烯酸甲酯嵌段共聚物P(S-b-MMA)纳米结构膜的方法。同时基于P(S-b-MMA)共聚物纳米结构膜的电化学模板聚合研究表明,该法可在神经元传感器电极表面获得理想的发丝状高粗糙度和高表面积PPy/PSS导电高聚物涂层。肖迎红 杨俊颜 David C.Martin 2003电子元件与材料2003,22,11:3

5Lipopolysaccharide immune stimulation but not β-mannanase supplementation affects maintenance energy requirements in young weaned pigs显示文摘Background: Pathogen or diet-induced immune activation can partition energy and nutrients away from growth,but clear relationships between immune responses and the direction and magnitude of energy partitioning responses have yet to be elucidated. The objectives were to determine how β-mannanase supplementation and lipopolysaccharide(LPS) immune stimulation affect maintenance energy requirements(ME_m) and to characterize immune parameters, digestibility, growth performance, and energy balance.Methods: In a randomized complete block design, 30 young weaned pigs were assigned to either the control treatment(CON; basal corn, soybean meal and soybean hul s diet), the enzyme treatment(ENZ; basal diet + 0.056% β-mannanase),or the immune system stimulation treatment(ISS; basal diet + 0.056% β-mannanase, chal enged with repeated increasing doses of Escherichia coli LPS). The experiment consisted of a 10-d adaptation period, 5-d digestibility and nitrogen balance measurement, 22 h of heat production(HP) measurements, and 12 h of fasting HP measurements in indirect calorimetry chambers. The immune chal enge consisted of 4 injections of either LPS(ISS) or sterile saline(CON and ENZ), one every48 h beginning on d 10. Blood was collected pre-and post-challenge for complete blood counts with differential,haptoglobin and mannan binding lectin, 12 cytokines, and glucose and insulin concentrations.Results: Beta-mannanase supplementation did not affect immune status, nutrient digestibility, growth performance,energy balance, or MEm. The ISS treatment induced fever, elevated proinflammatory cytokines and decreased leukocyte concentrations(P < 0.05). The ISS treatment did not impact nitrogen balance or nutrient digestibility(P > 0.10),but increased total HP(21%) and MEm(23%), resulting in decreased lipid deposition(-30%) and average daily gain(-18%)(P < 0.05).Conclusions: This experiment provides novel data on β-mannanase supplementation effects on immune parameters and energy balance in pigs and is the first to directly relate decreased ADG to increased MEm independent of changes in feed intake in immune challenged pigs. Immune stimulation increased energy partitioning to the immune system by 23% which limited lipid deposition and weight gain. Understanding energy and nutrient partitioning in immune-stressed pigs may provide insight into more effective feeding and management strategies.Nichole F.Huntley C.Martin Nyachoti John F.Patience 2018Journal of Animal Science and Biotechnology2018,9,4:1

8新型导电高聚物对神经元修补元件的表面改性显示文摘利用一种新型的导电聚合物——聚3,4-二氧化乙烷噻吩(PEDOT)的衍生物PEDTM,成功地在用微加工技术制作的神经元修补元件的电极上制得了导电涂层。该导电聚合物既克服了聚吡咯由于α—β(β?键接而产生的缺陷, 又克服了EDOT在水中溶解度小,无法在生物分子的掺杂下电化学合成PEDOT/生物分子导电涂层的缺陷。SEM和AFM照片表明PEDTM/PSS导电涂层具有粗糙的表面形貌,表面积增加,其阻抗也比未涂层前降低很多,在1 kHz处其阻抗值降低了两个数量级。研究结果表明,PEDTM/生物分子导电涂层的阻抗比聚吡咯/生物分子涂层降低得更多。肖迎红 David C.Martin 2003电子元件与材料2003,22,8:1

10Output digitization of simple measure-preserving linear systems显示文摘We examine three simple linear systems from the viewpoint of ergodic theory.We digitize the output and record only the sign of the output at integer times.We show that even with this minimal output we can recover important information about the systems.In particular,for a two-dimensional system viewed as a fow on the circle,we can determine the rate of rotation.We then use these results to determine the slope of the trajectories for constant irrational fow on the two-dimensional torus.To achieve this,we randomize the system by partitioning the state space and only recording which partition the state is in at each integer time.We show directly that these systems have entropy zero.Finally,we examine two four-dimensional systems and reduce them to the study of linear fows on the two-dimensional torus.A.DeStefano M.Thitsa C.Martin 2021Control Theory and Technology2021,19,4:1
11高纤维日粮对猪营养和代谢的影响:简介和定性分析方法显示文摘人们将大量低成本的纤维副产物纳入到猪日粮中以降低养猪成本。但是,富含纤维的日粮其营养价值通常较低,因为猪无法降解日粮纤维。另外,高纤维日粮会降低猪的养分利用率和生产性能。最近的报道通常相互矛盾,高纤维日粮的负面效应受纤维来源、类型和水平的影响。此外,日粮纤维对猪生长和生理效应的影响常常被检测日粮纤维及其组分的分析方法的多样性混淆。人们采取了多种策略来缓解高纤维日粮对猪的负面影响,并力求改善这种日粮的营养价值。外源性纤维降解酶应用广泛,主要用于提高养分利用率和猪的生产性能。然而,相关研究报道的结果并不一致,因此有必要阐明外源酶对饲喂高纤维日粮猪的代谢和生理反应的作用方式。另一方面,人们也越来越多地将日粮纤维用作提高猪肠道健康和妊娠母猪福利的手段。本综述将探讨日粮纤维对猪营养、肠道生理和母猪福利的影响。此外,在需要进一步研究的领域中,我们建议更深入地探究日粮纤维以及外源酶提高猪对高纤维日粮利用率的具体机制。韩浩月(译) 唐彩琰(审) Atta K.Agyekum C.Martin Nyachoti 2019国外畜牧学(猪与禽)2019,39,2:1
