    摘要: A system for determining image intensity of a radiograph includes an illuminator for providing lighting to the radiograph, an image reference standard having a predetermined color, a digital imaging device for obtaining a digital image of the radiograph and the image reference standard, a computer for receiving and storing the digital image and for executing programs, and an image analysis program being executed on the computer for providing a first image intensity value of a target area in the radiograph and a second image intensity value of the image reference standard and for computing a normalized image intensity value of the target area using the first and second image intensity values. In one embodiment, the image reference standard is an image reference standard of a black color or a white color.

    摘要: Methods for compression molding through holes in polymer layers are provided, as are the resulting patterned polymer layers. Two key aspects of the invention are provision of a mold and substrate having different mechanical hardness, and provision of room for local flow of material. These aspects of the invention facilitate formation of through holes by compression molding that are not blocked or partially blocked by undesirable material. These polymer layers can be formed into three dimensional patterned structures by bonding patterned layers together. Since the layers include through holes, a three-dimensional polymer pattern can be formed. These patterned polymer layers and three dimensionally patterned polymer constructs have a wide variety of applications. For example, these constructs can be used for fabrication of micro-fluidic devices, and/or can be used for various medical and biological applications including drug delivery devices and tissue engineering devices.

    摘要: A method for in vivo, ex vivo and in vitro regeneration of cartilage, collagen and bone remodeling by intermittently applied hydrostatic pressure consisting of repeated periods of applied hydrostatic pressure followed and interrupted by periods of recovery. The intermittent hydrostatic pressure is applied at physiological levels 5-10 MPA for an interval of 4 hours followed by a recovery period up to about 20 hours. The interval loading results in the selective inhibition of matrix degrading enzymes, pro-inflammatory cytokines and chemokines that attract inflammatory cells into the joint cavity and in selective decrease of gene expression of growth factors that are inhibitory to type II collagen expression.
