Friedreich ataxia (FRDA), the most common autosomal recessive neurodegenerative disease among Europeans and people of European descent, is characterized by an early onset (usually before the age of 25), progressive ataxia, sensory loss, absence of tendon reflexes and pyramidal weakness of the legs. We have recently identified a unique group of patients(More)
BACKGROUND The benefit of cytoreductive nephrectomy (CN) for overall survival (OS) is unclear in patients with synchronous metastatic renal cell carcinoma (mRCC) in the era of targeted therapy. OBJECTIVE To determine OS benefit of CN compared with no CN in mRCC patients treated with targeted therapies. DESIGN, SETTING, AND PARTICIPANTS Retrospective(More)
BACKGROUND In a phase II, open-label, multicentre Japanese study, sunitinib demonstrated antitumour activity and acceptable tolerability in metastatic renal cell carcinoma patients. Final survival analyses and updated results are reported. METHODS Fifty-one Japanese patients with a clear-cell component of metastatic renal cell carcinoma (25(More)
BACKGROUND AND PURPOSE White matter alteration in iNPH has not been well-investigated. TBSS is a voxelwise statistical analysis developed for DTI data. We aimed to elucidate the cerebral white matter alteration in patients with iNPH by using DTI and to test the accuracy of TBSS analysis. MATERIALS AND METHODS DTI data were obtained from 20 patients with(More)
BACKGROUND AND PURPOSE Previous neuropathologic studies in chronic hydrocephalus have suggested the presence of white matter damage, presumably from mechanical pressure due to ventricular enlargement and metabolic derangement. This study aimed to investigate the diffusional properties of the CST in patients with iNPH by using DTI and to determine whether(More)
BACKGROUND Several promising molecular-targeted drugs are used for advanced renal cancers. However, complete remission is rarely achieved, because none of the drugs targets a key molecule that is specific to the cancer, or is associated with "oncogene addiction" (dependence on one or a few oncogenes for cell survival) of renal cancer. Recently, an(More)
Vascular endothelial growth factor (VEGF), one of the most potent angiogenic factors, is suggested to play a crucial role in tumor neovascularization and is associated with tumor progression and metastasis in prostate cancer. This study evaluated the significance of the VEGF T-460C polymorphism in the risk and the progression of prostate cancer. In a(More)
We used localized 1H-magnetic resonance spectroscopy (MRS) to study the metabolic changes in the brains of patients with migraine during the interictal period. Measurement of metabolite levels in the occipital visual cortex in six normal subjects and six patients disclosed high lactate levels in the five patients who had experienced a migraine attack within(More)
The present study was designed to investigate the effect of capsaicin, a pungent component of red pepper, on the sympathetic nervous system (SNS) activity and energy metabolism in 16 age- and height-matched lean and obese young women. The sympatho-vagal activities were assessed by means of spectral analysis of heart rate variability (HRV) during the resting(More)
Anti-washout-type fast-setting calcium phosphate cement using chitosan (aw-FSCPC(chi)), conventional CPC (c-CPC), CPC mixed with citric acid (CPC(citric)) and CPC mixed with polyacrylic acid (CPC(acrylic)) were implanted subcutaneously in rats immediately after mixing to shed some light on the understanding of the appearance of excellent tissue response to(More)
