    LAPODS: a computer program for refinement of lattice parameters using optimal regression (2000)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 33 (2000), S. 1177-1179 
    Details
    ISSN: 1600-5767

    Notes: LAPODS is an upgraded version of the program LAPOD for the refinement of lattice parameters using the method of Cohen [Langford (1971). J. Appl. Cryst. 4, 259–260]. The improved version has a number of advanced features. It can detect the most significant systematic errors automatically by means of a statistical F test; it can also operate in a manual mode with corrections set by the user or input manually. The single-value decomposition (SVD) method is used so that the refinement is now more stable. The general formula to calculate the specimen-transparency error has been incorporated and a transparency correction can now be made when the absorption is intermediate between the limiting cases of `thick' or `thin' samples.

    The Expression of Cdk5, p35, p39, and Cdk5 Kinase Activity in Developing, Adult, and Aged Rat Brains (2000)

    Notes: Abstract The expression of cyclin-dependent kinase 5 (Cdk5) and its regulatory subunits, p35 and p39, was investigated in rat brain from embryonic day 12 (E12) to postnatal 18 months (18M). The Cdk5 protein levels increased from E12 to postnatal day 7 (P7) and remained at this level until 18M. The Cdk5 kinase activity and the levels of both p35 mRNA and protein were low at E12, became prominent at E18-P14 but then decreased in the adult and aged rat brains of 3M to 18M. In comparison, the expression pattern of p39 appeared to have an inverse relationship to that of Cdk5 and p35. In regional distribution studies, p35 protein levels and Cdk5 kinase activity were significantly higher in the cerebral cortex and hippocampus, but lower in the cerebellum and striatum. These results suggested that Cdk5, p35 and p39 might have region-specific and developmental stage-specific functions in rat brain.

    Mechanics of Leukocyte Deformation and Adhesion to Endothelium in Shear Flow (1999)
    Springer

    Notes: Abstract The mechanics of leukocyte [white blood cell (WBC)] deformation and adhesion to endothelial cells (EC) in shear flow has been investigated. Experimental data on transient WBC–EC adhesion were obtained from in vivo measurements. Microscopic images of WBC–EC contact during incipient WBC rolling revealed that for a given wall shear stress, the contact area increases with time as new bonds are formed at the leading edge, and then decreases with time as the trailing edge of the WBC membrane peels away from the EC. A two-dimensional model (2D) was developed consisting of an elastic ring adhered to a surface under fluid stresses. This ring represents an actin-rich WBC cortical layer and contains an incompressible fluid as the cell interior. All molecular bonds are modeled as elastic springs distributed in the WBC–EC contact region. Variations of the proportionality between wall shear stress (τ w ) in the vicinity of the WBC and the resulting drag force (F s ), i.e., Fs/τw, reveal its decrease with WBC deformation and increasing vessel channel height (2D). The computations also find that the peeling zone between adherent WBC and EC may account for less than 5% of the total contact interface. Computational studies describe the WBC–EC adhesion and the extent of WBC deformation during the adhesive process. © 1999 Biomedical Engineering Society. PAC99: 8717-d, 8719Tt, 8717Aa

    miR-10a restores human mesenchymal stem cell differentiation by repressing KLF4 (2013)
    Wiley-Blackwell
    Details
    Publication Date: 2013-05-22
    Description: miRNAs have recently been shown to play a significant role in human aging. However, data demonstrating the effects of aging-related miRNAs in human mesenchymal stem cells (hMSCs) are limited. We observed that hMSC differentiation decreased with aging. We also identified that miR-10a expression was significantly decreased with age by comparing the miRNA expression of hMSCs derived from young and aged individuals. Therefore, we hypothesized that the downregulation of miR-10a may be associated with the decreased differentiation capability of hMSCs from aged individuals. Lentiviral constructs were used to up- or downregulate miR-10a in young and old hMSCs. Upregulation of miR-10a resulted in increased differentiation to adipogenic, osteogenic, and chondrogenic lineages and in reduced cell senescence. Conversely, downregulation of miR-10a resulted in decreased cell differentiation and increased cell senescence. A chimeric luciferase reporter system was generated, tagged with the full-length 3'-UTR region of KLF4 harboring the seed-matched sequence with or without four nucleotide mutations. These constructs were cotransfected with the miR-10a mimic into cells. The luciferase activity was significantly repressed by the miR-10a mimic, proving the direct binding of miR-10a to the 3'-UTR of KLF4. Direct suppression of KLF4 in aged hMSCs increased cell differentiation and decreased cell senescence. In conclusion, miR-10a restores the differentiation capability of aged hMSCs through repression of KLF4. Aging-related miRNAs may have broad applications in the restoration of cell dysfunction caused by aging. J. Cell. Physiol. © 2013 Wiley Periodicals, Inc.

    A strategy for trade monitoring and substitution of the organs of threatened animals (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-11-01
    Description: The use of threatened animals as a source of traditional medicines is accelerating the extinction of such species and imposes great challenges to animal conservation. In this study, we propose a feasible strategy for the conservation of threatened medicinal animals that combines trade monitoring and the search for substitutes. First, DNA barcoding provides a powerful technique for monitoring the trade of animal species, which helps in restricting the excessive use and illegal trade of such species. Second, pharmacological tests have been adopted to evaluate the biological equivalence of threatened and domestic animals; based on such testing, potential substitutes are recommended. Based on a review of threatened animal species and their substitutes, we find that the search for substitutes deserves special attention; however, this work is far from complete. These results may be of great value for the conservation of threatened animals and maintaining the heritage of traditional medicine. Scientific Reports 3 doi: 10.1038/srep03108
