Chelativorans intermedius sp. nov. and proposal to reclassify Thermovum composti as Chelativorans composti comb. nov.

Two Gram-stain-negative, non-endospore-forming, rod-shaped bacteria, strains CC-MHSW-5(T) and A1392, were isolated from water of coastal hot springs located in Taiwan and China, respectively, and investigated for their taxonomic position. The two strains shared identical 16S rRNA gene sequences, a DNA-DNA hybridization value >80% and similar genomic DNA G+C contents (64.3 and 64.

Amphiplicatus metriothermophilus gen. nov., sp. nov., a thermotolerant alphaproteobacterium isolated from a hot spring.

A thermotolerant, Gram-strain-negative, non-spore-forming and strictly aerobic bacterium, designated GU51(T), was isolated from Guhai hot spring in Jimsar county, Xinjiang province, north-west China. Each cell of strain GU51(T) consisted of an oval body and two symmetrical long (3-6 µm) prosthecae. The strain moved by polar flagellum.

[Expression of LIM mineralization protein-1 in the apical papilla and dental pulp tissues of human teeth].

Objective: To examine the expression of LIM mineralization protein-1 (LMP-1) in the apical papilla and dental pulp tissues of human immature permanent teeth and to investigate the role of LMP-1 in the development and maturation of pulp-dentin complex.

Methods: Forty-eight healthy premolars in need of extraction for orthodontic treatment were obtained with 24 immature permanent teeth and 24 mature permanent teeth. After extraction, the apical papilla was detached from the dental pulp in the immature permanent tooth and the dental pulp of mature permanent tooth was rapidly removed.

Anoxybacillus vitaminiphilus sp. nov., a strictly aerobic and moderately thermophilic bacterium isolated from a hot spring.

A strictly aerobic, Gram-stain-positive, motile and spore-forming bacterium, strain 3nP4(T), was isolated from the Puge hot spring located in the south-western geothermal area of China. Strain 3nP4(T) grew at 38-66 °C (optimum 57-60 °C), at pH 6.0-9.

[The precise assignment of whispering gallery modes for lasing spectra emitting from cylindrical micro-cavities].

Lasers with spherical or cylindrical dielectric resonators supported by whispering gallery modes (WGM) have attracted much interest due to their microscopic size, high cavity Q factor, and low lasing threshold. Cylindrical microcavity lasers based on the gain only in the evanescent field region of whispering gallery modes have been demonstrated in our recent works. The gain was excited by the evanescent wave of longitudinal optical pumping along the optical fiber.
