| 1 | MnO_2纳米粒子固载纤维素酶用于高效水解农业废弃物制备生物乙醇(英文)显示文摘纤维素酶是一种有效的纤维质类物质水解催化剂,工业应用时可通过固定化纤维素酶来降低其成本.本文将烟曲霉原变种JCF产生的纤维素酶固定在Mn O2纳米颗粒上.MnO2可提高纤维素酶的活性,并充当一个更好的载体.采用扫描电镜表征了所制MnO2纳米粒子及其负载纤维素酶的表面性质,以傅里叶变换红外光谱分析了固定在MnO2纳米粒子上纤维素酶的官能团性质.纤维素酶在MnO2纳米粒子上最大的固定化效率为75%.考察了固定化纤维素酶的活性、操作pH值、温度、热稳定性和重复使用性等性质.结果表明,所制固定化酶的稳定性比游离酶更高.固定于MnO2纳米粒子上的纤维素酶可用于纤维质类物质的水解反应,且能在较宽的温度和pH值范围内使用.表征结果证实了该催化剂具有非常高的催化纤维素类物质水解的活性. | Elsa Cherian Mahendradas Dharmendirakumar Gurunathan Baskar | 2015 | 催化学报2015，36，8： | 7 |
| 2 | Thermal conductivity of complex materials显示文摘In the discussion and analysis of thermal properties(e.g.heat capacity,thermal conductivity)the Debye approximation is typically used to describe the collective behavior of lattice vibrations(phonons)in solid materials.Because the Debye model has been successful in explaining many properties of materials,particularly in contrast to the non-dispersive model considered by Einstein,the Debye model is often the starting point of introductory textbooks in solid state physics.Yet the more we learn about the full spectrum of lattice vibrations. | G.Jeffrey Snyder Matthias T.Agne Ramya Gurunathan | 2019 | National Science Review2019，6，3： | 6 |
| 3 | The role of extracellular vesicles in animal reproduction and diseases显示文摘Extracellular vesicles(EVs)are nanosized membrane-enclosed compartments that serve as messengers in cell-to-cell communication,both in normal physiology and in pathological conditions.EVs can transfer functional proteins and genetic information to alter the phenotype and function of recipient cells,which undergo different changes that positively affect their structural and functional integrity.Biological fluids are enriched with several subpopulations of EVs,including exosomes,microvesicles(MVs),and apoptotic bodies carrying several cargoes,such as lipids,proteins,and nucleic acids.EVs associated with the reproductive system are actively involved in the regulation of different physiological events,including gamete maturation,fertilization,and embryo and fetal development.EVs can influence follicle development,oocyte maturation,embryo production,and endometrial-conceptus communication.EVs loaded with cargoes are used to diagnose various diseases,including pregnancy disorders;however,these are dependent on the type of cell of origin and pathological characteristics.EV-derived microRNAs(miRNAs)and proteins in the placenta regulate inflammatory responses and trophoblast invasion through intercellular delivery in the placental microenvironment.This review presents evidence regarding the types of extracellular vesicles,and general aspects of isolation,purification,and characterization of EVs,particularly from various types of embryos.Further,we discuss EVs as mediators and messengers in reproductive biology,the effects of EVs on placentation and pregnancy disorders,the role of EVs in animal reproduction,in the male reproductive system,and mother and embryo cross-communication.In addition,we emphasize the role of microRNAs in embryo implantation and the role of EVs in reproductive and therapeutic medicine.Finally,we discuss the future perspectives of EVs in reproductive biology. | Sangiliyandi Gurunathan Min-Hee Kang Hyuk Song Nam Hyung Kim Jin-Hoi Kim | 2022 | Journal of Animal Science and Biotechnology2022，13，6： | 4 |
