BACKGROUND To evaluate the value of diffusion-weighted imaging (DWI) for distinguishing between benign and malignant renal masses. MATERIAL/METHODS Seventy-five patients with 75 unilateral renal lesions were included, and 75 normal contralateral kidneys served as controls. The lesions were categorized into four groups as malignant cystic, malignant solid, benign cystic and benign solid. The a...
PURPOSE To report on the optic canal cross-sectional area (OCA) in Caucasian patients with normal-tension glaucoma (NTG) compared with Caucasian control subjects without known optic nerve (ON) diseases. METHODS Retrospective analysis of computed tomographic images of the cranium and orbits in 56 NTG patients (30 females and 26 males; 99 of 112 eyes; mean age 67.7 ± 11.1 years). Fifty-six age-...
Disseminated prostate cancer cells must survive in circulation for metastasis to occur. Mechanisms by which these cells survive are not well understood. By immunohistochemistry of human tissues, we found that levels ofb1 integrins and integrin-induced autophosphorylation of FAK (pFAK-Y397) are increased in prostate cancer cells in primary prostate cancer and lymph node metastases, suggesting th...
OBJECTIVES Computed diffusion-weighted magnetic resonance imaging (cDWI) refers to the synthesizing of arbitrary b value diffusion-weighted images (DWI) from a set of measured b value images by voxelwise fitting. The objectives of this study were to quantitatively analyze the noise and the contrast-to-noise ratio (CNR) in cDWI as a function of b value by numerical simulations and by measurement...
BACKGROUND On the basis of brachytherapy experience, edge stenosis has been raised as a potential limitation for drug-eluting stents. We used serial intravascular ultrasound (IVUS) to prospectively analyze vessel responses in adjacent reference segments after implantation of polymer-controlled paclitaxel-eluting stents. METHODS AND RESULTS TAXUS II was a randomized, double-blind trial with 2 ...
PURPOSE To investigate intravoxel incoherent motion (IVIM) MRI for evaluating the sensitivity of radiotherapy on nasopharyngeal carcinoma (NPC). RESULTS The reproducibility between intra-observer and inter-observer was relatively good. D (0.72×10-3 mm2/s±0.14 vs. 0.54×10-3 mm2/s±0.23; P < 0.001) and D* (157.92×10-3 mm2/s±15.21 vs. 120.36×10-3 mm2/s±10.22; P < 0.0001) were significantly higher...
Th e cry3Aa11 gene of Bacillus thuringiensis strain Mm2 (B. thuringiensis Mm2) was PCR-amplifi ed and cloned into E. coli/B. thuringiensis shuttle vector pHT315. Th e recombinant plasmid carrying the cry3Aa11 gene was introduced into the parental B. thuringiensis Mm2. Th e toxin production capacities of parental and recombinant strains grown in DSM, containing either 50 mM or 200 mM inorganic p...
