PURPOSE To report the outcomes of mallet fractures treated with our modified tension band wiring technique. METHODS Eleven men and two women (mean age; 33 years) with mallet fractures in which happened more than five weeks before surgery, or with fracture fragments involving more than 2/3 or less than 1/3 of the distal phalanx articular surface or with(More)
STUDY DESIGN The effect of edaravone, a novel free radical scavenger, was assessed functionally and histologically using a rat spinal cord contusion model. OBJECTIVE To investigate the effect of edaravone on neuroprotection after spinal cord injury in rats. SUMMARY OF BACKGROUND DATA The spinal cord injury results in immediate physical damage (primary(More)
BACKGROUND In our previous study, allogeneic-transplanted peripheral nerve segments preserved for one month in a polyphenol solution at 4°C could regenerate nerves in rodents demonstrated the same extent of nerve regeneration as isogeneic fresh nerve grafts. The present study investigated whether the same results could be obtained in a canine model. (More)
BACKGROUND There have been several reports that partial ulnar transfer (PUNT) is preferable for reconstructing elbow flexion in patients with upper brachial plexus injuries (BPIs) compared with intercostal nerve transfer (ICNT). The purpose of this study was to compare the recovery of elbow flexion between patients subjected to PUNT and patients subjected(More)
High-speed and low-power techniques are described for megabit-class size-configurable CMOS SRAM macrocells. To shorten the design turn-around-time, the methodology of abutting nine kinds of leaf cells is employed; two-level via-hole programming and the array-address decoder embedded in each control leaf cell present a divided-memory-array structure. A new(More)
The varying states of water confined in the nano-domain structures of typical room temperature ionic liquids (ILs) were investigated by (1)H NMR and by measurements of self-diffusion coefficients while systematically varying the IL cations and anions. The NMR peaks for water in BF4-based ILs were clearly split, indicating the presence of two discrete states(More)
BACKGROUND Previous animal studies demonstrated that the sensory and motor functions in ipsilesional upper limbs that had been reconstructed by CC7 transfer eventually associated with the contralesional brain cortices that had originally mediated the functions of the ipsilesional upper limbs before brachial plexus injury (BPI). Our hypothesis was that the(More)
We investigated the effects of a free radical scavenger, MCI-186 (edaravone), on neuroprotection in the rat post-traumatic spinal cord using various doses and routes of administration. The injury was produced with a weight-drop device. Lipid peroxide formation in the spinal cord was measured using the thiobarbituric acid test for malonyldialdehyde (MDA). In(More)
BACKGROUND The nerve root avulsion injury causes decrease of motor neurons in the spinal ventral horn. To investigate the motoneuron death after avulsion injury in rats, the intradural root avulsion procedure is usually used, although it is technically demanding and associated with a risk of unexpected spinal cord damage. We have developed a new cervical(More)
BACKGROUND The development of effective immunosuppressive regimens has resulted in many cases of successful hand transplantation. Visual skin inspection and histological evaluation are used to assess the rejection of hand transplants, but these methods are largely subjective. In this study, we aimed to determine the potential of microRNAs (miRNAs) as(More)
