    Notes: Abstract Background: To identify the most useful combinations of various pre- and postcontrast magnetic resonance (MR) image sequences in detecting hepatocellular carcinoma (HCC) and its intrahepatic metastases before and after injection of SHU-555-A. Methods: Thirty-eight lesions in 16 patients were evaluated before and after administration of SHU-555-A by using fast spin echo (FSE), gradient echo (GRE), and echo planar (EP) imaging sequences using a 1.5-Tesla superconducting MR system. The signal intensity ratio (SIR) and contrast-to-noise ratio (CNR) of the lesions, signal-to-noise ratios, and other parameters were calculated. Results: Tumors were better detected after injection of SHU-555-A on all pulse sequences except on out-of-phase T1-weighted (T1W)-GRE sequences. Tumor detectability was higher for precontrast EP imaging and T2*-weighted (T2*W)-GRE sequences, whereas detectability at postcontrast was higher for T2*W-GRE, proton-density-weighted-FSE, and in-phase T1W-GRE sequences. The SIR and CNR at precontrast were highest for EP imaging, and those at postcontrast were highest for T2*W-GRE. Conclusion: SHU-555-A will increase the detectability of HCC and its liver metastases. T1W- and T2*W-GRE sequences would be the sequences of choice.

    Ablation characteristics of Au, Ag, and Cu metals using a femtosecond Ti:sapphire laser (1999)

    Notes: Abstract. Femtosecond laser ablation of metallic bulk crystals of Au, Ag and Cu was experimentally studied with laser pulse widths ranging from 120 fs through 800 fs at a center wavelength of 780 nm for micro-machining applications. Two different ablation regimes were found in terms of the laser fluence. The characteristic length of different ablation regimes was explained in terms of the optical skin depth and thermal diffusion length; it was determined by the peak electron temperature in the two-temperature model. The lateral feature of the two ablation regimes is discriminated by the amount of particles accumulated by the evaporation process. Ablated particle was observed less in the lower fluence regime than in the higher fluence regime, but there was no significant difference on the ablated surface. The parameters used in the two-temperature model, are discussed in order to model the ultrashort pulsed laser ablation process theoretically. It is shown that the obtainable range of the lower fluence regime is enhanced with the shorter pulse lasers, because the ablation etch rate is decreased with longer pulse width.

    Time-resolved two-dimensional thick-slice magnetic resonance digital subtraction angiography in assessing brain tumors (2000)

    Notes: Abstract. The aim of this study was to evaluate clinical applicability of two-dimensional (2D) thick-slice, contrast-enhanced magnetic resonance digital subtraction angiography (MRDSA) with high temporal resolution in diagnosis of brain tumors. Forty-four patients with brain tumors including, 15 meningiomas, 8 gliomas, 6 metastatic tumors, 4 neuromas, and 2 hemangioblastomas, were studied with 2D MRDSA with frame rate approximately 1 s. Images were continuously obtained following the initiation of bolus injection of gadolinium chelates for 40 s and subtraction images were generated in a workstation. We evaluated visualization of normal cranial vessels on MRDSA and compared MRDSA and intra-arterial digital subtraction angiography (IADSA) with regard to hemodynamic information. Large cerebral arteries, all venous sinuses, and most tributaries were clearly visualized. A stain was present in hypervascular tumors including all 15 meningiomas and 2 hemangioblastomas on MRDSA. Presence of a stain demonstrated on MRDSA and that on IADSA coincided in 16 of 20 cases (Spearman rank correlation value was 0.85). The location, shape, and phase of the stain on MRDSA were similar to those on IADSA. Two-dimensional MRDSA with high temporal resolution has a unique ability to demonstrate cerebral hemodynamics, such as IADSA, and can play an important role in assessing brain tumors.

    Notes: In Ni-13.0at%Si-3.1at%Fe alloy, when γ/γ’ two-phase microstructure formed at 1123 K isisothermally heated at 923 K which is lower than the temperature where the initial γ/γ’ microstructureforms, the phase-separation of γ/γ’ precipitate phase occurs and γ particles newly appear in eachcuboidal γ’ precipitate. While in Ni-10.2at%Al-10.8at%Fe alloy, when γ/γ’ two-phase microstructureformed at 1023 K is isothermally heated at 1123 K which is higher than the temperature where theinitial γ/γ’ microstructure forms, the phase-separation of γ’ precipitate phase takes place and γparticles newly appear in each cuboidal γ’ precipitate. Such appearance of new γ particles in γ’precipitates can be explained by the difference in the volume fraction of γ phase that should exist inthe γ/γ’ two-phase system depending on the heating temperature

    Notes: When the Al/Ge/SiO2 bilayer films are annealed in-situ in a scanning electron microscope(SEM) at the temperatures lower than the crystallization temperature of amorphous Ge itself, theso-called metal-mediated-crystallization (MMC) takes place. In the course of MMC, crystalline Geaggregates (Ge clusters) form in the bilayer films, which results in the formation and the evolution ofimpressive fractal patterns with branching on the free surface. In-situ SEM observations of annealedAl/Ge/SiO2 bilayer films indicate that the grain size of polycrystalline Al-layer influences thenucleation of Ge clusters and hence of fractal patterns. For the bilayer films containing larger Algrains, the nucleation rate of fractal patterns (Ge clusters) is faster and the number of patterns is larger

    Notes: Based on direct spectrophotometry and the oxidation of ascorbic acid by guaiacol peroxidase, this method was simple, rapid and highly specific for ascorbic acid. No interference was seen for any food sample tested, including vegetables, fruits, potatoes, beans, chicken liver, processed food, tea and seaweed. This method was applicable to colored and/or sugar-rich samples, and more precise than officially adopted chemical methods.
