Deer antlers can be developed into multiple novel models to study growth and development of tissues for biomedical research. To facilitate this process, we have invented and further refined five custom-built tools through three decades of antler research. These are: 1. Pedicle growth detector to pinpoint the timing when pedicle growth is initiated, thus stimuli for pedicle and first antler form...

OBJECTIVE To determine the shear strength of BioGlue Surgical Adhesive (Cryolife Inc, Kennesaw, Georgia) for use in periosteal fixation in endoscopic browplasty. METHODS In a controlled design, the shear strength of periosteal attachment to native bone and that of dissected periosteum affixed to bone with BioGlue surgical adhesive was physiologically determined. Twenty-one periosteum and bone...

: The periosteum, a composite cellular connective tissue, bounds all nonarticular bone surfaces. Like Velcro, collagenous Sharpey's fibers anchor the periosteum in a prestressed state to the underlying bone. The periosteum provides a niche for mesenchymal stem cells. Periosteal lifting, as well as injury, causes cells residing in the periosteum (PDCs) to change from an immobile, quiescent state...

Residual periosteum developed periosteal bone formation in the pocket 10 years after cranioplasty, lumpectomy was conducted on the left lower abdomen under local anesthesia. Pathological sections revealed abundant osteocytes and mature bone matrix, and confirmed the bone formation on the residual periosteum.

OBJECTIVE It is widely known that stress conditioning can protect microcirculation and induce the release of vasoactive factors for a period of several hours. Little, however, is known about the long-term effects of stress conditioning on microcirculation, especially on the microcirculation of the periosteum of the calvaria. For this reason, we used intravital fluorescence microscopy to investi...

permanent facial paralysis is a catastrophic event for involved patients. in long lasting paralysis with severe facial muscles atrophy, masseter muscle transfer is a very good choice. but its greatest problem is postoperative elongation of flap and gradual diminishing of early results and loss of symmetry. this article advocate a new modification for resolving this problem with concomitant elev...

Objectives: To investigate the early influence of periosteum removal on osteocytes in mouse calvaria. Material and methods: Fifteen C57BL/6 male mice were used in this study. Under anesthesia, a 2X3mm rectangular shape periosteum, 2mm behind the coronal suture and 1mm beside the sagittal suture, was surgically removed from the left side of calvaria whereas the right side was intact as control. ...
