    Notes: Abstract. Among 54 patients with thoracic esophageal carcinoma (53 squamous cell carcinoma, 1 adenosquamous carcinoma), the usefulness of MR sagittal imaging for evaluating local extent (T factor) was examined by measuring the anteroposterior (AP) diameter of the tumor. The MR examination was performed using ECG gated scans with a 3 mm slice at 1.5 Tesla. T1-weighted sagittal images were obtained. In 10 patients the appearance of the esophagus was normal, and in 44 patients a tumor was detected in the sagittal section. Thirty-seven lesions were histologically proved (Tis, 1; T1, 3; T2, 3; T3, 15; T4, 15). Lesions classified as 〈T2 were not visible, and the appearance of the esophagus was normal. The tumors detected in sagittal section were T3 (15 tumors) or T4 (15 tumors). The mean diameter of T4 lesions (34.0 ± 7.9 mm, range 24–57 mm) was larger than that of T3 lesions (25.0 ± 4.4 mm, range 18–33 mm) (p 〈 0.05). Only two masses with an AP diameter 〉 30 mm were resected. They were located in the lower esophagus. It is concluded that lesions detected in MR sagittal images might be T3 or T4 tumors, and masses of 〉30 mm might extend to adjacent organs, although two tumors with an AP diameter 〈 25 mm also invaded the trachea.

    Development of a phosphate-removal system using a marine photosynthetic bacterium Chromatium sp. (1997)

    Notes: Abstract The marine photosynthetic bacterium Chromatium sp. successfully removed orthophosphate when grown phototrophically. The phosphate-uptake rate was almost constant at more than 5.0 mg- PO4 3−/l in synthetic medium. Addition of seawater causes flocculation of this strain. The successful use of seawater as an inexpensive source of magnesium could prove to be effective in the removal of photosynthetic bacterial cells from a medium. A semicontinuous culture system was used for the removal of low concentrations of phosphate and the phosphate-uptake activity of Chromatium sp. was maintained under 0.1 day−1 dilution rate. This strain was also able to remove high concentrations of phosphate from domestic sewage.

    Extracellular reduction of selenite by a novel marine photosynthetic bacterium (1997)

    Notes: Abstract A novel purple nonsulfur bacterium strain NKPB030619, which has resistance to over 5 mM selenite, was isolated from a marine environment. An initial concentration of 1.1 mM selenite, added to the medium, was decreased to under 0.05 mM within 5 days. The color of the cell suspension turned red within 2 days. The red coloration gradually decreased and black precipitates appeared during 2 weeks of cultivation. Under these conditions, two main types of deposit were formed extracellularly. These deposits were thought to contain red amorphous selenium and black vitreous selenium. The selenite reduction to elemental selenium in this bacterium was induced by the introduction of light and l-malic acid under anaerobic conditions. These results suggest that selenite reduction is coupled with photosynthesis and l-malic acid can serve as the indirect electron donor for its reduction. Phylogenetic analysis based on the 16S rDNA sequence showed that NKPB0360619 belongs to the α subdivision of Proteobacteria and is classified into the Rhodobacter species. The highest similarity of 86.2% was observed with R. sphaeroides.
