Four full-thickness skin wounds made in normal mice led to the significant increase in levels of nerve growth factor (NGF) in sera and in wounded skin tissues. Since sialoadenectomy before the wounds inhibited the rise in serum levels of NGF, the NGF may be released from the salivary gland into the blood stream after the wounds. In contrast, the fact that(More)
Penicillium herquei IFO 4674 is a filamentous fungus that produces a large amount of hydrolases for fibrous polysaccharides. We purified two beta-xylosidases, S1 and S2. The molecular masses of S1 and S2 determined by MALDI-TOF-MS were 103,700 and 37,460 Da. The optimum pHs of S1 and S2 were 4.0 and 6.5, respectively. By several kinds of alcohols,(More)
OBJECTIVE A variety of factors may affect the surgical outcome in patients with cervical spondylotic myelopathy. The aim of this study is to analyze the prognostic factors by comparing younger and elderly patient groups on the basis of preoperative radiological and clinical data. METHODS To assess the prognostic factors after surgery had been performed,(More)
CONTEXT The impairment of insulin sensitivity, a marker of surgical stress, is important for outcomes. OBJECTIVE The aim was to assess the association between the quality of preoperative glycemic control, intraoperative insulin sensitivity, and adverse events after cardiac surgery. DESIGN AND SETTING We conducted a prospective cohort study at a tertiary(More)
Preservation of facial nerve function is one of the most important goals in acoustic neuroma surgery. We have been using intraoperative continuous monitoring of evoked facial nerve electromyograms (EMGs) since 1997 in acoustic neuroma surgery. We therefore investigated surgically treated patients to clarify the usefulness of this monitoring, and to(More)
To present a case of melanoma-associated retinopathy (MAR) associated with an intranasal melanoma. A 77-year-old Japanese man visited us complaining of night blindness, blurred vision, and color vision difficulties in both eyes. His best-corrected visual acuity was 0.7 in the right and 1.0 in the left eyes. The rod response of the electroretinogram (ERG)(More)
Chondrodysplastic dwarfism in Japanese brown cattle is an autosomal recessive disorder characterized by short limbs. Previously, we mapped the locus responsible for the disease on the distal end of bovine chromosome 6. Here, we narrowed the critical region to approximately 2 cM by using linkage analysis, constructed a BAC and YAC contig covering this(More)
HYPOTHESIS We investigated whether inflammatory biomarkers and stress are involved in the pathophysiology of idiopathic sensorineural hearing loss (ISHL). STUDY DESIGN Individual cohort study. SETTING Two tertiary centers. PATIENTS Forty-three ISHL and 10 non-ISHL patients seen in our ENT departments from 2004 to 2010 within a week from the onset of(More)
Giant cell tumors are benign tumors commonly found in the long bones. Rarely, they may occur in the larynx, and patients with such tumors may present with hoarseness and anterior neck swelling. Since Wessely reported the first case of laryngeal giant cell tumor in 1940, 30 cases have been identified. Herein, we present a case of a 31-year-old man with giant(More)
Usher syndrome is an autosomal recessive disorder manifesting hearing loss, retinitis pigmentosa and vestibular dysfunction, and having three clinical subtypes. Usher syndrome type 1 is the most severe subtype due to its profound hearing loss, lack of vestibular responses, and retinitis pigmentosa that appears in prepuberty. Six of the corresponding genes(More)
