| 1 | Collagen/hyaluronan based hydrogels releasing sulfated hyaluronan improve dermal wound healing in diabetic mice via reducing inflammatory macrophage activity显示文摘Sustained inflammation associated with dysregulated macrophage activation prevents tissue formation and healing of chronic wounds.Control of inflammation and immune cell functions thus represents a promising approach in the development of advanced therapeutic strategies.Here we describe immunomodulatory hyaluronan/collagen(HA-AC/coll)-based hydrogels containing high-sulfated hyaluronan(sHA)as immunoregulatory component for the modulation of inflammatory macrophage activities in disturbed wound healing.Solute sHA downregulates inflammatory activities of bone marrow-derived and tissue-resident macrophages in vitro.This further affects macrophage-mediated pro-inflammatory activation of skin cells as shown in skin ex-vivo cultures.In a mouse model of acute skin inflammation,intradermal injection of sHA downregulates the inflammatory processes in the skin.This is associated with the promotion of an anti-inflammatory gene signature in skin macrophages indicating a shift of their activation profile.For in vivo translation,we designed HA-AC/coll hydrogels allowing delivery of sHA into wounds over a period of at least one week.Their immunoregulatory capacity was analyzed in a translational experimental approach in skin wounds of diabetic db/db mice,an established model for disturbed wound healing.The sHA-releasing hydrogels improved defective tissue repair with reduced inflammation,augmented pro-regenerative macrophage activation,increased vascularization,and accelerated new tissue formation and wound closure. | Sophia Hauck Paula Zager Norbert Halfter Elke Wandel Marta Torregrossa Ainur Kakpenova Sandra Rother Michelle Ordieres Susann Räthel Albrecht Berg Stephanie Möller Matthias Schnabelrauch Jan C.Simon Vera Hintze Sandra Franz | 2021 | Bioactive Materials2021,6,12: | 7 |
| 2 | 齿轮-轴承系统非线性振动混沌吸引子周期轨道控制显示文摘考虑轴承支撑齿轮传动系统建立了含多间隙的系统非线性动力学模型,模型中考虑了时变啮合刚度和综合传动误差等因素。基于OGY混沌控制改进策略对高维非双曲齿轮系统实施了多周期混沌控制,采用Newton-Raphson迭代法搜寻了P1、P2、P4和P8等多组不稳定周期轨道(Unstable Periodic Orbits,UPO)不动点,求解了各UPO解对应的Jacobi矩阵特征值和局部参数敏感度矢量,结合Poincaré截面等工具解析了混沌吸引子向P10周期轨道转换时的轨道间隔及迁移特性。在2 000周期步下对混沌吸引子实施了P1、P2、P4、P8和P10等多种周期组合式控制,结果表明在状态转换阶段,尤其30周期步内控制参数摄动量发生激增,此后恢复稳定且保持与目标控制轨道相同周期的状态演化;多周期轨道持续控制时周期状态越高,控制难度越大,所需参数摄动量相应增加。研究结果在理论上有助于齿轮系统混沌响应减振控制。 | 林何 屈文宽 MATTHIAS R tsch 王三民 | 2020 | 振动与冲击2020,39,13: | 6 |
| 3 | 基于G-P算法关联维数齿轮系统相空间吸引子数值特性显示文摘为有效刻画齿轮系统相空间吸引子结构的数值特性,建立了直齿轮系统含间隙与综合传动误差的非线性动力学模型,基于G-P算法推导了等间隔的齿轮系统吸引子关联维数计算公式。对周期运动和混沌运动吸引子,采用Lyapunov指数与关联维数等手段定量表征其数值特性,利用Poin caré截面法定性分析了混沌吸引子的演化和迁移进程。通过关联维数对阻尼比和综合传动误差变化下的混沌吸引子演化行为进行了追踪刻画,结果表明,吸引子结构越复杂则关联维数越大,系统振动越敏感,混沌吸引子关联维数值介于整数1和2之间,具有分数维特征。 | 林何 Matthias R?tsch 王三民 胥光申 | 2019 | 机械传动2019,43,7: | 5 |

| 6 | Femtojoule electro-optic modulation using a silicon– organic hybrid device显示文摘Energy-efficient electro-optic modulators are at the heart of short-reach optical interconnects,and silicon photonics is considered the leading technology for realizing such devices.However,the performance of all-silicon devices is limited by intrinsic material properties.In particular,the absence of linear electro-optic effects in silicon renders the integration of energy-efficient photonic–electronic interfaces challenging.Silicon–organic hybrid(SOH)integration can overcome these limitations by combining nanophotonic silicon waveguides with organic cladding materials,thereby offering the prospect of designing optical properties by molecular engineering.In this paper,we demonstrate an SOH Mach–Zehnder modulator with unprecedented efficiency:the 1-mm-long device consumes only 0.7 fJ bit^(-1) to generate a 12.5 Gbit s^(-1) data stream with a bit-error ratio below the threshold for hard-decision forward-error correction.This power consumption represents the lowest value demonstrated for a non-resonant Mach–Zehnder modulator in any material system.It is enabled by a novel class of organic electro-optic materials that are designed for high chromophore density and enhanced molecular orientation.The device features an electro-optic coefficient of r33<180 pm V^(-1) and can be operated at data rates of up to 40 Gbit s^(-1). | Sebastian Koeber Robert Palmer Matthias Lauermann Wolfgang Heni Delwin L Elder Dietmar Korn Markus Woessner Luca Alloatti Swen Koenig Philipp C Schindler Hui Yu Wim Bogaerts Larry R Dalton Wolfgang Freude Juerg Leuthold Christian Koos | 2015 | Light(Science & Applications)2015,4,1: | 4 |
| 7 | Dysfunctional stem and progenitor cells impair fracture healing with age显示文摘Successful fracture healing requires the simultaneous regeneration of both the bone and vasculature;mesenchymal stem cells (MSCs) are directed to replace the bone tissue, while endothelial progenitor cells (EPCs) form the new vasculature that supplies blood to the fracture site. In the elderly, the healing process is slowed, partly due to decreased regenerative function of these stem and progenitor cells. MSCs from older individuals are impaired with regard to cell number, proliferative capacity, ability to migrate, and osteochondrogenic differentiation potential. The proliferation, migration and function of EPCs are also compromised with advanced age. Although the reasons for cellular dysfunction with age are complex and multidimensional, reduced expression of growth factors, accumulation of oxidative damage from reactive oxygen species, and altered signaling of the Sirtuin-1 pathway are contributing factors to aging at the cellular level of both MSCs and EPCs. Because of these geriatric-specific issues, effective treatment for fracture repair may require new therapeutic techniques to restore cellular function. Some suggested directions for potential treatments include cellular therapies, pharmacological agents, treatments targeting age-related molecular mechanisms, and physical therapeutics. Advanced age is the primary risk factor for a fracture, due to the low bone mass and inferior bone quality associated with aging;a better understanding of the dysfunctional behavior of the aging cell will provide a foundation for new treatments to decrease healing time and reduce the development of complications during the extended recovery from fracture healing in the elderly. | Diane R Wagner Sonali Karnik Zachary J Gunderson Jeffery J Nielsen Alanna Fennimore Hunter J Promer Jonathan W Lowery M Terry Loghmani Philip S Low Todd O McKinley Melissa A Kacena Matthias Clauss Jiliang Li | 2019 | World Journal of Stem Cells2019,11,6: | 3 |
