A thermophilic nonspore-forming rod isolated from hay compost in Korea was subjected to a taxonomic study. The microorganism, designated as SC- IT, was identified as a nitrate-reducing and nonmotile bacterium. Although the strain was negatively Gram-stained, a KOH test showed that the strain SC-1^(T) belonged to a Cram-positive species. Growth was observed between 45 and 70℃. The optimal growth temperature and pH were 60℃ and pH 7.5, respectively. The G+C content of the genomic DNA was 65 mol% and the major quinone types were MK-6 and MK-7. A phylogenetic analysis based on 16s rDNA sequences revealed that the strain SC- 1' was most closely related to Symbiohacteriurn thermophilum. However, the level of DNA-DNA relatedness between strain SC- I' and the type strain for Symbiohacteriurn thermophilum was approximately 30%. Accordingly, on the basis of the phenotypic traits and molecular systematic data, the strain SC-I^(T) would appear to represent a new species within the genus Symbiobacterium. The type strain for the new species is named SC-1^(T) (=KCTC 0307BP^(T); DSM 15906^(T)).
Molecular Characterization of Two Strains of Porcine Group C Rotavirus

Group C rotaviruses are an important cause of acute gastroenteritis in humans and animals. Fecal samples were collected from a porcine herd in July, 2009. Group C rotavirus RNA was detected using RT-PCR for the VP6 gene. The identified strain was further characterized by sequencing and phylogenetic analysis of the partial VP4, and complete VP6 and VP7 gene sequences. The partial VP4 and complete VP6 gene sequences of the CUK-5 strain were most closely related to those of the CUK-6 strain of group C rotaviruses. Phylogenetic analysis of the VP7 gene of the 2 strains (CUK-5 and CUK-6) and reference strains of group G rotavirus by the neighbor-joining method also confirmed that CUK-5 and CUK-6 belonged to type G5 and G1 strains, respectively. This study provides useful data for the prediction of newly appearing variants of porcine group C rotaviruses in neighboring countries through comparisons with GCRVs and fundamental research for vaccine development.

<P>We suggested that the neutral line is a more effective location for a superconducting fault current limiter (SFCL) in a three-phase power system. To confirm it, we analyzed the quench and recovery characteristics of SFCL applied into the neutral line in cases of non-symmetrical ground faults, such as single line-to-ground and double line-to-ground faults. Through a comparative analysis based on the experimental results for two SFCLs applied either to the neutral line or to the three-phase power line, it was confirmed that the SFCL applied into the neutral line of the power system was more advantageous from the viewpoint of both the practical use of the SFCL and the SFCL's coordination with other related protective devices in the power system.</P>

A 92-year-old woman visited hospital with edema of both lower extremities. Computed tomography showed Inferior vena cava (IVC) compressed by huge hepatic cyst. Massive IVC thrombosis and pulmonary thromboembolism (PTE) were also observed. Medical treatment rather than radiologic intervention was preferred due to elderly age and poor performance status of the patient. IVC thrombosis and PTE were disappeared after anticoagulation therapy for 6months. By our knowledge, this is first report of IVC thrombosis caused by congenital hepatic cyst in English literature.
HspA and HtpG Enhance Thermotolerance in the Cyanobacterium, Microcystis aeruginosa NIES-298

Heat shock proteins (Hsps) play a key role in the cellular defense response to diverse environmental stresses. Here, the role of Hsp genes in the acquisition of thermotolerance in the cyanobacterium Microcystis aeruginosa NIES-298 was investigated. Twelve Hsp-related genes were examined to observe their modulated expression patterns at different temperatures (10, 15, 25, and 35oC) over different exposure periods. HspA and HtpG transcripts showed an up-regulation of expression at low temperatures (10 and 15oC) and high temperature (35oC), compared with the control (25oC). To examine their effects upon thermotolerance, we purified recombinant HspA and HtpG proteins. During a thermotolerance study at 54oC, the HspA-transformed bacteria showed increased thermotolerance compared with the control. HtpG also played a role in the defense response to acute heat stress within 30 min. These findings provide a better understanding of cellular protection mechanisms against heat stress in cyanobacteria.
