Effects of administration of granulocyte colony-stimulating factor (G-CSF) on the regeneration of injured mammalian skeletal muscles were studied in male C57BL/6J mice. Muscle injury was induced by injection of cardiotoxin (CTX) into tibialis anterior muscles bilaterally. G-CSF was administrated for 8 consecutive days from 3 days before and 5 days after the(More)
BACKGROUND Various attempts have been made to assess the inclination angle of the acetabulum utilizing new imageprocessing technologies to enable three-dimensional reconstruction of the acetabulum. However, reliability of these methods has not been estimated in comparison with anatomical measurements. This study developed a geometric method for measuring(More)
INTRODUCTION Associations between accessory anterolateral talar facet (AALTF) and sinus tarsi pain in adults have not been reported. This study aimed to investigate the clinical and imaging characteristics of pathologic conditions of the peritalar region in adults with painful accessory talar facet impingement (ATFI). METHODS We included 31 patients (aged(More)
A 15-year-old male complained of pain in the left foot that occurred when changing direction while running and at presentation, he had difficulty in walking due to pain and swelling. Plain X-ray of the foot revealed a Myerson Type B2 Lisfranc fracture dislocation, and 3-D computed tomography (CT) revealed proximal fractures of the 2nd-4th metatarsals. The(More)
BACKGROUND Extracts of Tripterygium wilfordii Hook F (TWHF), a traditional Chinese herb, have been reported to show efficacy in patients with rheumatoid arthritis (RA). Since RA is not only characterized by inflammation but also by synovial proliferation in the joints, we examined whether triptolide (a constituent of TWHF) could influence the proliferation(More)
We report the usefulness of hook of hamate pull test (HHPT), described by Wright et al. in 2010, along with therapeutic outcomes of hook of hamate fractures. Eleven patients (two with fresh fractures and nine with nonunion) were studied. The fractures were diagnosed with HHPT for recently encountered 4 patients and a definitive diagnosis was made by a(More)
The ability to improve the technique for an accurate clinical diagnosis of the injury of interosseous membrane of the forearm (IOM) associated with forearm fractures and dislocations is important for its treatment and prognosis. Ultrasound examination of the IOM in 46 forearms from 18 normal volunteers, five patients with restricted forearm pronation and(More)
BACKGROUND We examined the anatomical features of the accessory antero-lateral talar facet (AALTF) in adults. METHODS The sample comprised 44 feet (male: 10 cadavers and 20 feet; female: 12 cadavers and 24 feet) obtained from 22 cadavers used for systemic autopsy. The mean age was 86.5 years. The talus and calcaneus were obtained from the autopsy(More)
BACKGROUND Skeletal muscle stem cells, so-called muscle satellite cells, are responsible for the repair and the regeneration of adult skeletal muscle tissues. Heat stress can facilitate the proliferation and the differentiation of myoblasts in vitro and can enhance their proliferative potential, which may stimulate the regrowth of atrophied skeletal muscle.(More)
Effects of heat shock transcription factor 1 (HSF1) gene on the regrowth of atrophied mouse soleus muscles were studied. Both HSF1-null and wild-type mice were subjected to continuous hindlimb suspension for 2 wk followed by 4 wk of ambulation recovery. There was no difference in the magnitude of suspension-related decrease of muscle weight, protein(More)
