This paper compares the changing skill structure of wage bills and employment in the United States with six other OECD countries (Denmark, France, Germany, Japan, Sweden, and the United Kingdom). We investigate whether a directly observed measure of technical change (R&D intensity) is closely linked to the growth in the importance of more highly skilled(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)
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 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)
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)
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)
Buspirone hydrochloride (buspirone), an anxiolytic drug, was administered orally to pregnant Crj: CD (Sprague-Dawley) rats from day 17 of gestation through day 20 of postpartum at dose levels of 2, 12 and 75 mg/kg/day. The summarized results obtained are as follows: 1. Decreased activity was observed for F0 dams at buspirone 75 mg/kg. Further, the(More)
BACKGROUND Although autologous nerve grafting is the gold standard treatment of peripheral nerve injuries, several alternative methods have been developed, including nerve conduits that use supportive cells. However, the seeding efficacy and viability of supportive cells injected in nerve grafts remain unclear. Here, we focused on a novel completely(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)
Surgical treatment for recurrent, common peroneal neuropathy has not been reported. Herein, we describe a successfully treated case using the proximally based sural fasciocutaneous flap after reneurolysis of the adhesive common peroneal nerve. A 33-year-old man received a neurolysis operation for entrapment neuropathy of the common peroneal nerve 2 years(More)
