BACKGROUND Rieske non-heme iron aromatic ring-hydroxylating oxygenases (RHOs) are multi-component enzyme systems that are remarkably diverse in bacteria isolated from diverse habitats. Since the first classification in 1990, there has been a need to devise a new classification scheme for these enzymes because many RHOs have been discovered, which do not(More)
Fungal endophytes were isolated from 1-, 2-, 3-, and 4-year-old ginseng roots (Panax ginseng Meyer) cultivated in Korea. The isolated fungal endophytes were identified based on sequence analysis of the internal transcribed spacer and morphological characterization by microscopic observations. A total of 81 fungal endophytes were isolated from 24 ginseng(More)
In order to develop a novel system for the discrimination of five ginseng cultivars (Panax ginseng Meyer), single nucleotide polymorphism (SNP) genotyping assays with real-time polymerase chain reaction were conducted. Nucleotide substitution in gDNA library clones of P. ginseng cv. Yunpoong was targeted for the SNP genotyping assay. From these SNP sites, a(More)
Panax ginseng roots are well known for their medicinal properties and have been used in Korean and Chinese traditional medicines for 1000s of years. However, the medicinal value of P. ginseng fruits remain poorly characterized. In this study, we used an integrated biochemical, proteomics, and metabolomics approach to look into the medicinal properties of(More)
Sphingomonas chungbukensis DJ77 is a novel aromatic hydrocarbon-degrading bacterium capable of growing on phenanthrene as its sole source of carbon and energy. In this study, the protein expression profiles of S. chungbukensis DJ77 grown in the presence of phenanthrene were investigated by using two-dimensional gel electrophoresis (2-DE). Among 1000 protein(More)
We performed de novo transcriptome sequencing for Panax ginseng and Panax quinquefolius accessions using the 454 GS FLX Titanium System and discovered annotation-based genome-wide single-nucleotide polymorphism (SNPs) using next-generation ginseng transcriptome data without reference genome sequence. The comprehensive transcriptome characterization with the(More)
As a result of aging population, the incidence of pelvic insufficiency fracture has been increasing. Pain-related immobility caused by pelvic insufficiency fractures may result in a serious dependency and high mortality with preexisting comorbidities. We present two cases of pelvic insufficiency fracture in elderly patients which had good clinical outcome(More)
