A Gram-positive, cream-coloured, non-motile, rod-shaped actinomycete, designated DLS-10T, was isolated from a rock collected on the peak of Darangshi Oreum (a small mountain 300 m above sea level) in Jeju, Republic of Korea. The temperature and pH ranges for growth were 4-37 degrees C and pH 5.1-9.1. The organism grew at NaCl concentrations up to 3 % and(More)
Recent studies reported that the direct transformation of one differentiated somatic cell type into another is possible. In the present study, we were able to modulate the cell fate of somatic cells to take on male germ cell function by introducing cell extracts derived from porcine testis tissue. Fibroblasts were treated with streptolysin O, which(More)
OBJECTIVE Conventional pterional approach is a commonly used neurosurgical technique for the treatment of cerebral aneurysms. However, this technique requires more extensive brain exposure than other key hole approaches and is sometimes associated with surgical traumatization or cosmetic problems. The aim of this study was to compare the postoperative(More)
We studied the applicability of the Acute Physiology and Chronic Health Evaluation II (APACHE II) and Simplified Acute Physiology Score II (SAPS II) in patients admitted to the intensive care unit (ICU) with acute stroke and compared the results with the Glasgow Coma Scale (GCS) and National Institutes of Health Stroke Scale (NIHSS). We also conducted a(More)
The quantitative exposure to vibration for shipyard workers who have used several kinds of vibratory tools was studied. The dose-response relationship between lifetime exposure dose and hand-arm vibration syndrome also was studied. The study included 344 workers who were exposed to vibration in one shipyard and 53 unexposed workers in the same company.(More)
Cisplatin is a widely used chemotherapeutic agent in head and neck squamous cell carcinoma (HNSCC). Resistance to cisplatin is a common feature of HNSCC. To identify genes that may regulate cisplatin sensitivity, we carried out a cDNA microarray analysis of gene expression in cisplatin-sensitive and cisplatin-resistant HNSCC-derived cell lines. Among genes(More)
Ginseng has been reported to ameliorate hyperglycemia in experimental and clinical studies; however, its mechanism of action remains unclear. In this study, we investigated the metabolic effects and putative molecular mechanisms of Korean red ginseng (KRG, Panax ginseng) in animal models for type 2 diabetes mellitus (T2DM) and peripheral insulin-responsive(More)
Polarity formation in preimplantation embryos is controversial. To investigate the embryonic-abembryonic axis in the pig, porcine parthenotes were used to prevent the topological change caused by polyspermy as well as to avoid the influences of sperm entry position. For lineage tracing, DiI, a fluorescence dye, was injected into only a blastomere of the(More)
The introduction of fixed relays is expected to be inevitable as 4G wireless communications coverage is expanded and data processing ratios enhanced, and for reducing costs of base station extension and backhaul communication network holding. Additional interference is an unwanted concomitant of adding many fixed relays to the existing cellular system(More)
A sphenoid mucocele often presents late due to its deep seated anatomical site. And it has varied presentation due to its loose relationship to the cavernous sinus and the base of the skull. We describe a case of large sphenoid sinus mucocele. A middle aged old man suddenly developed third cranial nerve palsy. Brain imaging study revealed an isolated(More)
