1农业气象教育和培训的现状与未来需求显示文摘农业气象学是研究农业与气象条件之间相互关系及其规律的科学,它既是应用气象学的一个分支,又是农学的一门基础学科。其基本任务就在于研究这些农业自然资源和农业自然灾害的时空分布规律,为农业的区划和规划、作物的合理布局、Lomas J Milford J R Mukhala E 吉春容 邹陈 2010沙漠与绿洲气象2010,4,4:7
2General review of magnetic resonance elastography显示文摘Magnetic resonance elastography(MRE) is an innovative imaging technique for the non-invasive quantification of the biomechanical properties of soft tissues via the direct visualization of propagating shear waves in vivo using a modified phase-contrast magnetic resonance imaging(MRI) sequence. Fundamentally,MRE employs the same physical property that physicians utilize when performing manual palpation- that healthy and diseased tissues can be differentiated on the basis of widely differing mechanical stiffness. By performing 'virtual palpation ',MRE is able to provide information that is beyond the capabilities of conventional morphologic imaging modalities. In an era of increasing adoption of multi-parametric imaging approaches for solving complex problems,MRE can be seamlessly incorporated into a standard MRI examination to provide a rapid,reliable and comprehensive imaging evaluation at a single patient appointment. Originally described by the Mayo Clinic in 1995,the technique represents the most accurate non-invasive method for the detection and staging of liver fibrosis and is currently performed in more than 100 centers worldwide. In this general review,the mechanical properties of soft tissues,principles of MRE,clinical applications of MRE in the liver and beyond,and limitations and future directions of this discipline-are discussed. Selected diagrams and images are provided for illustration.Gavin Low Scott A Kruse David J Lomas 2016World Journal of Radiology2016,8,1:5
3Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) supports adhesion and migration of mesenchymal stem cells and tenocytes显示文摘AIM: To establish the potential of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) as a material for tendon repair. METHODS: The biocompatibility of PHBHHx with both rat tenocytes (rT) and human mesenchymal stem cells (hMSC) was explored by monitoring adhesive characteristics on films of varying weight/volume ratios coupled to a culture atmosphere of either 21% O2 (air) or 2% O2 (physiological normoxia). The diameter and stiffness of PHBHHx films was established using optical coherence tomography and mechanical testing, respectively. RESULTS: Film thickness correlated directly with weight/volume PHBHHx (r2 = 0.9473) ranging from 0.1 mm (0.8% weight/volume) to 0.19 mm (2.4% weight/volume). Film stiffness on the other hand displayed a biphasic response which increased rapidly at values > 1.6% weight/volume. Optimal cell attachment of rT required films of ≥ 1.6% and ≥ 2.0% weight/volume PHBHHx in 2% O2 and 21% O2 respectively. A qualitative adhesion increase was noted for hMSC in films ≥ 1.2% weight/volume, becoming significant at 2% weight/volume in 2% O2. An increase in cell adhesion was also noted with ≥ 2% weight/volume PHBHHx in 21% O2. Cell migration into films was not observed. CONCLUSION: This evaluation demonstrates that PHBHHx is a suitable polymer for future cell/polymer replacement strategies in tendon repair.Alex J Lomas George GQ Chen Alicia J El Haj Nicholas R Forsyth 2012World Journal of Stem Cells2012,4,9:2
