In order to investigate the relationship between metabolic state and myoelectrical activity in working muscle during short term intense exercise, eleven healthy males performed isokinetic knee extensions at an angular velocity of 180 deg · sec−1 for 30 and 60 s. The median frequency (MF) of the surface electromyogram (EMG) recorded from vastus lateralis was… (More)
Keloid is a fibrotic disease characterized by abnormal accumulation of extracellular matrix in the dermis. The keloid matrix contains excess collagen and glycosaminoglycans (GAGs), but lacks elastic fiber. However, the roles of these matrix components in the pathogenesis of keloid are largely unknown. Here, we show that elastin and DANCE (also known as… (More)
We successfully transplanted two free posterior interosseous artery perforator flaps that had been harvested simultaneously from a single posterior interosseous artery system to the index and middle fingers of a 19-year-old man. Our case suggests that multiple free perforator flaps can be prepared from a single posterior interosseous artery system.
A second toe plantar flap was attached to the donor site after a free first toe pulp flap. Twenty-two days postoperatively, the wound had almost healed. Although the whole defect is impossible to cover with this flap, partial resurfacing will reduce the healing time and morbidity from recurrent ulceration.
Keloids are a proliferative fibrotic disease characterized by abnormal accumulation of extracellular matrix in the dermis. Keloid lesions lack skin plasticity due to deficiencies in elastic fiber formation in the extracellular matrix. The loss of elastic fiber is caused by excessive accumulation of chondroitin sulfate (CS), a sulfated glycosaminoglycan.… (More)
We have treated keloids using a combination of surgical excision and postoperative irradiation. The objective of this study was to evaluate the results of our treatment over 12 years. From 1995 until 2006, we treated keloids using the aforementioned treatment. If we identified a sign of recurrence during the follow-up period, we started an intralesional… (More)
The objective of this study was to investigate the effects of latent TGF-β binding protein 4 (LTBP-4) on elastic fiber regeneration in three-dimensional cultures of human dermal fibroblasts (HDFs). Appropriate collagen scaffold for elastic fiber regeneration was also examined. Collagen sponges cross-linked at 120 °C and composed of small pores (25 μm on… (More)
Skin-derived precursor (SKP) cells are a valuable resource for tissue engineering and regenerative medicine, because they represent multipotent stem cells that differentiate into neural and mesodermal progenies. Previous studies suggest that the stem cell pool decreases with age. Here, we show that human multipotent SKP cells can be efficiently collected… (More)
A 52-year-old male complained of numbness and radiating pain affecting the plantar region of his left foot. He was found to have recurrent tarsal tunnel syndrome due to posterior tibial nerve compression by 3 different types of ganglion during a 12-year period. To the best of our knowledge, a similar case has not been documented. At the first operation,… (More)
