We constructed a bacterial artificial chromosome (BAC) library, designated as KBrH, from high molecular weight genomic DNA of Brassica rapa ssp. pekinensis (Chinese cabbage). This library, which was constructed using HindIII-cleaved genomic DNA, consists of 56,592 clones with average insert size of 115 kbp. Using a partially duplicated DNA sequence of(More)
We estimated the genome size of Korean ginseng ( Panax ginseng C.A. Meyer), a medicinal herb, constructed a Hin dIII BAC library, and analyzed BAC-end sequences to provide an initial characterization of the library. The 1C nuclear DNA content of Korean ginseng was estimated to be 3.33 pg (3.12×103 Mb). The BAC library consists of 106,368 clones with an(More)
The purpose of this study was to assess the genetic variation and establish the relationship amongst breeds and strains using 15 chicken specific microsatellite markers. A total of 285 unrelated DNA samples from four Korean native chicken strains (Black strain of Korean native chicken; KL, Red Brown strain of Korean native chicken; KR, Ogol strain of Korean(More)
Nanobiotechnology raises fascinating possibilities for new analytical assays in various fields such as bioelectronic assembly, biomechanics and sampling techniques, as well as in chips or micromachined devices. Recently, nanotechnology has greatly impacted biotechnological research with its potential applications in smart devices that can operate at the(More)
Effects of temperature and salinity on the growth of the two agarophytes, Gracilaria verrucosa (Hudson) Papenfuss and Gracilaria chorda Holmes were examined in Korea. Both species grew over a wide range of temperatures (10–30 ∘C) and salinities (5–35‰), and grew well at 17–30 ∘C and a salinity of 15–30‰. In culture, G. verrucosa grew faster than G. chorda(More)
We present a case of a completely isolated enteric duplication cyst in a 28-year-old man. Computed tomography showed a large complex cystic mass with curvilinear and nodular calcifications near the anterior aspect of the left kidney. It had no connection to the pancreas, stomach, small bowel, or large bowel. We found no report describing computed(More)
The carcino-embryonic antigen-related cell adhesion molecule (CEACAM)2 is produced in many feeding control centres in the brain, but not in peripheral insulin-targeted tissues. Global Ceacam2 null mutation causes insulin resistance and obesity resulting from hyperphagia and hypometabolism in female Ceacam2 homozygous null mutant mice (Cc2 [also known as(More)
A 32-year-old woman with a long-standing systemic lupus erythematosus had multiple subcutaneous nodules on her axillae, iliac crests and limbs. Three years ago, these nodules began to appear and slowly became larger. Some of them amassed to form a large, fungating, lobulated mass on her right iliac crest. Roentgenographic and histological examination showed(More)
RAPD (random amplified polymorphic DNA) markers generated by 15 arbitrary decamers were used to determine the frequency of DNA polymorphism in 39 watermelon [Citrullus lanantus (Thunb.) Mansf.] germplasms. Of the 15 primers tested, all except 1 (primer 275) directed the amplification of polymorphic products. A total of 162 amplification products were(More)
Sizeand time-resolved aerosol samples were collected using an eight-stage Davis rotating unit for monitoring (DRUM) sampler from 29 March to 29 May in 2002 at Gosan, Jeju Island, Korea, which is one of the representative background sites in East Asia. These samples were analyzed using synchrotron X-ray fluorescence for 3-h average concentrations of 19(More)
