Mutations in the mitofusin 2 (MFN2) gene, which encodes a mitochondrial GTPase mitofusin protein, have recently been reported to cause both Charcot-Marie-Tooth 2A (CMT2A) and hereditary motor and sensory neuropathy VI (HMSN VI). It is well known that HMSN VI is an axonal CMT neuropathy with optic atrophy. However, the differences between CMT2A and HMSN VI(More)
Although myxoid liposarcoma is a subtype of liposarcoma, it may be difficult to establish the correct diagnosis with magnetic resonance (MR) imaging due to the lack of fat signal intensity. Without the administration of gadolinium contrast material, the tumor may even mimic a cystic tumor. A spectrum of MR imaging abnormalities occur in myxoid liposarcoma,(More)
PURPOSE Our goal was to describe the MR appearance of distal femoral cortical irregularity (DFCI). METHOD With plain radiographs and MR images of 100 knees, the presence of DFCIs was determined, and the shapes of DFCIs were classified into three subgroups: concave, convex, and divergent cortical shapes. Radiographic and MR shapes of DFCIs were compared.(More)
The authors treated 16 patients with tuberculosis of the sacroiliac joint. Twelve were treated surgically and four were treated conservatively. The clinical symptoms were buttock and low back pain in all patients, and most had difficulty walking (68.6%) and had radicular pain in their lower limbs (50%). Of the 16 patients, four (15%) had associated(More)
OBJECTIVE The objective of our study was to analyze MR images of vascular leiomyoma of the extremity and to compare these images with histopathologic findings to determine if a correlation exists. CONCLUSION T2-weighted MR images of vascular leiomyoma of an extremity showed a mass with mixed areas that were both hyper- and isointense to skeletal muscle(More)
The current study evaluates the role of quantitative measurement of peripheral lymphocyte subsets, especially CD4+ helper T-cell recovery, in predicting transplant outcomes including overall survival (OS) and non-relapse mortality (NRM) after allogeneic stem cell transplantation. A total of 69 allogeneic recipients were included with following diagnoses:(More)
This study demonstrates for the first time the effects of IL-1beta on the regulation of protein production as well as MUC2 gene transcription in cultured human airway epithelial cells. The effect of IL-1beta on the regulation of MUC2 protein was determined by flow cytometric analysis. The expression level of MUC2 induced by IL-1beta increased in a(More)
OBJECTIVE The purpose of this study was to investigate the effect of metallic implant positioning on MR imaging artifacts, to determine the optimal imaging conditions for minimizing artifacts, and to show the usefulness of artifact-minimizing methods in imaging of the knee. MATERIALS AND METHODS Using MR images of experimental phantoms (titanium alloy and(More)
OBJECTIVES The purposes of this study were to evaluate the nature of the paraspinal soft tissue mass and the location of the lesion involved using magnetic resonance imaging and to correlate these observations with surgical findings. SUMMARY OF BACKGROUND DATA In the past, tuberculous spondylitis was diagnosed by plain radiography and since the 1970s,(More)
We investigated the possible involvement of the superoxide (.O2-) radical in alterations of vascular reactivity and phosphoinositide (PI) turnover in aortas from streptozotocin (STZ)-induced diabetic (4 week) rats. STZ treatment increased the maximal contractile response of the aorta to norepinephrine (NE), phenylephrine (PE) and high K+, whereas the(More)
