PURPOSE To evaluate whether apparent diffusion coefficients (ADCs) calculated from diffusion-weighted echo-planar magnetic resonance (MR) images can be used to characterize head and neck lesions. MATERIALS AND METHODS Diffusion-weighted echo-planar MR imaging was performed with a 1.5-T MR unit in 97 head and neck lesions in 97 patients. Images were(More)
A novel mannosylated cholesterol derivative, cholesten-5-yloxy-N-(4-((1-imino-2-beta-D-thiomannosyl -ethyl)amino)bu tyl) formamide (Man-C4-Chol), was synthesized in order to perform mannose receptor-mediated gene transfer with liposomes. Plasmid DNA encoding luciferase gene (pCMV-Luc) complexed with liposomes, consisting of a 6:4 mixture of Man-C4-Chol and(More)
The aim of this study was to evaluate the usefulness of annual screening for lung cancer by low-dose computed tomography (CT) and the characteristics of identified lung cancers. Subjects consisted of 5483 general population aged 40-74 years, who received initial CT scans in 1996, followed by repeat annual scans for most subjects in 1997 and 1998, with a(More)
The P30 movement protein (MP) of tomato mosaic tobamovirus (ToMV) is synthesized in the early stages of infection and is phosphorylated in vivo. Here, we determined that serine 37 and serine 238 in the ToMV MP are sites of phosphorylation. MP mutants in which serine was replaced by alanine at positions 37 and 238 (LQ37A238A) or at position 37 only (LQ37A)(More)
PURPOSE To determine the incidence of Xp11 translocation renal cell carcinoma (RCC) in adult patients using cytogenetics and immunohistochemstry. EXPERIMENTAL DESIGN Cytogenetic studies were prospectively done using tumor samples from 443 consecutive adult Japanese patients (ages 15-89 years) who underwent nephrectomy for RCC. TFE3 immunohistochemistry(More)
OBJECTIVES To evaluate whether three-dimensional 26-core (3D26) prostate biopsy improves the accuracy in predicting the presence of Gleason pattern 4/5 cancer compared with extended transrectal 12-core (TR12) or transperineal 14-core (TP14) biopsy schemes. METHODS We studied 143 consecutive men in whom prostate cancer was diagnosed by the 3D26 biopsy and(More)
PURPOSE We have previously reported the expression of aquaporin-7 (AQP7) in the rat testis and cloned human AQP7 from the testicular cDNA library. However, to our knowledge the spatial expression pattern and biological roles of AQP7 remain to be elucidated in humans. MATERIALS AND METHODS We investigated AQP7 expression in the human testis and ejaculated(More)
PURPOSE To describe the features of twisted ovarian tumors on computed tomographic (CT) scans and magnetic resonance (MR) images. MATERIALS AND METHODS The CT scans, MR images, clinical records, and histopathologic findings in 10 patients with surgical proof of a twisted adnexal tumor were retrospectively evaluated. RESULTS The most common findings on(More)
OBJECTIVE To assess the impact of preoperative C-reactive protein (CRP) levels on the prognosis in patients with upper urinary tract (UUT) urothelial carcinoma (UC) primarily treated surgically, as it is increasingly recognized that a systemic inflammatory response is associated with the prognosis for patients with various malignancies. PATIENTS AND(More)
OBJECTIVE To investigate the effect of C-reactive protein (CRP) level on the prognosis of patients with muscle-invasive bladder cancer treated with chemoradiotherapy (ChRT), as it is increasingly recognized that the presence of a systemic inflammatory response is associated with poor survival in various malignancies. PATIENTS AND METHODS The clinical(More)
