A full genomic DNA microarray technique was employed to investigate the effects of Dongchunghacho on aortal and hepatic gene expression in apolipoprotein E knockout mice fed a high-fat/high-cholesterol diet. Male 8- week - old ApoE-/- mice were randomly divided into two groups, control(high cholesterol group; HC) and supplementation of Dongchunghacho (SD). All of the mice were fed a high-fet/high cholesterol diet with or without Dongchunghacho supplemented by 1% for 6 weeks. At first, lipid profile of the Dongchunghacho was measured by biochemical analysis. No differences were observed in serum triglyceride and total cholesterol levels between the two groups. Antigenotoxic effect of the Dongchunghacho was measured by the single cell gel electrophoresis assay (Comet assay) and quantified as % fluorescence in tail. Dongchunghacho supplementation decreased significantly leukocytic DNA damage and also there was a tendency of reduction in hepatic DNA damage in Dongchunghacho group compared with the control group. In up regulated genes in liver and aorta of the mice, genes with 0 to 2- fold difference in expression level between the two group (HD and SD) was very much more in liver than in aorta, on the contrary, those with 2-fold to 16-flod difference increased greatly rather in aorta than in liver. Also, almost the same results were observed in down regulated genes in liver and aorta between the two groups. These results suggested that supplementation of Dongchunghacho might be helpful in preventing leukocytic DNA damage induced by high fat diet, and has a more crucial roles in aortal gene expression.

We analyzed the high resolution H,6 line spectra of CH Cygni obtained at the Bohyunsan Astronomical Observatory (BOAO) on April 2004. The temporal changes in the Hβ line profiles are reported. We obtained the equivalent widths of the Gaussian components. Using this we estimated the length of the gaseous nebula which emits the Hβ line and the mass loss rate from the star.

Although trisomy 16 is commonly detected in spontaneous abortions and accounts for over 30% of cases of autosomal trisomy detected after spontaneous abortion, trisomy 16 mosaicism is rarely detected by amniocentesis in the second trimester. Here, we report a case of level III trisomy 16 mosaicism (47,XX,+16[8]/46,XX[31]) diagnosed by cytogenetic analysis of independently cultured amniotic fluid cells. The female baby was delivered at full term with low birth weight and intrauterine growth retardation, and interestingly, her karyotype was normal (46,XX). Given the difficulty in predicting the outcomes of fetuses with this mosaicism, it is recommended to inform the possibility of mosaicisms including this trisomy 16 mosaicism during prenatal genetic diagnosis and genetic counseling for parents.

Mannitol is commonly used to reduce intracranial and intraocular pressures and to prevent dialysis-disequilibrium syndrome. However, intravenous mannitol infusion in various cases has the potential to result in acute kidney injury (AKI). We present a case of mannitol-induced AKI that developed after low dose mannitol infusion and resulted in recovery after hemodialysis. A 66-year-old woman was admitted to the hospital with a diagnosis of left middle cerebral artery infarction. On hospital day 5, cerebral edema was observed on a follow-up MRI. D-mannitol 35 g was given intravenously every 8 hours. Four days later, serum creatinine levels were elevated from 1.2 mg/dL to 3.5 mg/dL. The serum osmolal gap was found to be 52.4 mosm/kg H2O and urine output was reduced from 2.78 mL/kg/h to 0.69 mL/kg/h over three days. Hemodialysis over 2 hours was performed and renal function subsequently improved to baseline function. A potential risk of AKI exists even with low dose mannitol infusion in patients with advanced age, underlying renal impairment, and concomitant use of nephrotoxic agents. Mannitol-induced AKI may be rapidly reversed by short-term hemodialysis.

The isolated single coronary artery is a rare congenital anomaly, in which both coronary arteries arise from a solitary ostium. Diagnosis of coronary anomalies and identification of the exact anatomy of coronary arteries has significant clinical importance, hence, myocardial ischemia or sudden cardiac death is usually related to its course of anomalous coronary artery. Most patients with a single coronary artery are asymptomatic and have normal electrocardiogram and negative stress tests. However, if the patient has other structural abnormalities, for example, ventricular hypertrophy, the exam is determined. This report describes a case of single coronary artery, where the right coronary artery originated from the distal left circumflex artery in a patient with hypertrophic ardiomyopathy.

Molecular markers are useful for selecting to include superior character genetic like as strong immune system and rapid growth in fish. The marker is also very important part of breeding technology in Olive flounder (Paralichthys olivaceus). Single nucleotide polymorphisms (SNPs) marker is already in use widely for genomic research and breeding. But this SNPs marker hardly has been validated for screening functional genes in Olive flounder. We study identify single nucleotide polymorphisms (SNPs) on Expressed sequence tag (EST) database, develop usable SNP marker and apply to wild sample and cultured of olive flounder. As a result, Out of total 4.327 ESTs, 693contigs and 514 SNP from total contigs were detected while these substitutions include 297 transitions and 217 transversions. 144 developed markers were applied in 16 samples (wild 8, culture 8), Out of total marker, only 32 markers had detected polymorphic in sample. Polymorphism of 32 markers was observed in the variety genes region involved in immunity and protein synthesis. And the 32 marker were identified 21 transitions, 11 transversions, and indel was not detected in polymorphic SNPs. The analysis on heterozygosity by sample showed 0.34 in wild sample and 0.29 in cultured sample. In conclusion, we was identified SNP and Polymorphism by designed new marker, it supports that development marker is suitable for SNP detection and diversity analysis in Olive flounder. The outcome of this study can be basic data for researches for immunity gene and characteristic with SNP.

Although much effort has been made to find agronomically important loci in the soybean plant, extensive linkage disequilibrium and genome duplication have limited efficient genome-wide linkage analyses that can identify important regulatory genes. In this respect, recombination block-based analysis of cultivated plant genomes is a potential critical step for molecular breeding and target locus screening. We propose a new three-step method of detecting recombination blocks and comparative genomics of bred cultivars. It utilizes typical reshuffling features of their genomes, which have been generated by the recombination processes of breeding ancestral genomes. To begin with, mutations were detected by comparing genomes to a reference genome. Next, sequence blocks were examined for likenesses and difference with respect to the reference genome. The boundaries between the blocks were taken as recombination sites. All recombination sites found in the cultivar set were used to split the genomes, and the resulting sequence fragments were named as core recombination blocks (CRBs). Finally, the genomes were compared at the CRB level, instead of at the sequence level. In the genomes of the five Korean soybean cultivars used, the CRB-based comparative genomics method produced long and distinct CRBs that are as large as 22.9 Mb. We also demonstrated efficiency in detecting functionally useful target loci by using indel markers, each of which represents a CRB. We further showed that the CRB method is generally applicable to both monocot and dicot crops, by analyzing publicly available genomes of 31 soybeans and 23 rice accessions.

Acinetobacter baumannii is usually considered an opportunistic pathogen that it responsible for a variety of nosocomial infections, such as, pneumonia, tracheobronchitis, meningitis, endocarditis, peritonitis, skin and soft tissue infections, and urinary tract infections. However, over the years, the organism has developed substantial antimicrobial resistance, and thus, the management of infections has become more difficult. The less common infective endocarditis is one of the more serious consequences of nosocomial bacteremia. Here, we report the successful treatment of the first case of multidrug-resistant A. baumannii endocarditis in a 33-year-old patient.

Resequencing data is actively used for searching QTL or analyzing genetic diversity in the crops. However, the complexity of genome, caused by genome duplication, limits the utility of genome-wide association studies and linkage analyses to identify genes that regulate agronomically valuable traits. Here, we propose a comparative genomics approach based on core or common variation-based recombination blocks (CRB) using single nucleotide variation (SNV) density information. We found that the soybean genomes are assembled with long and distinct CRBs as large as 10Mb. CRB-based comparative genomics enabled us to accurately identify recombination blocks at the whole-chromosome level. We identified the Ih locus that determines the yellow hilum color in soybeans using CRB-based mapping with representative indel markers. These results suggest that the CRB-based comparison method is a promising platform for molecular breeding and map-based cloning.

This study was carried out to gain the basic informations about botanical characteristics of plant type and properties related to table quality for developing the new colored waxy corn hybrid. Materials used were produced by our laboratory in 2007 and their major traits were evaluated fro two years(2008 to 2009) at Corn Breeding Farm of Coll. of Agri. & Life in CNU. Items surveyed were major agricultural characteristics including ear length and traits related to edible. Botanical characteristics as a plant type and ear pattern of the developed waxy corn hybrids showed large ranges among them; stem height of CNU08H-h39 among used hybrids was the highest as 235.7cm, while CNUH08-15 was the lowest. Ear height of Daehackchal Gold 1 was the highest as 83.7cm and that of CNU08H-15 was the lowest among used hybrids. Ear length of CNU08H-h121 among used hybrids was the longest as 23.1cm, while that of CNU08H-71 was the smallest as 12.7cm. Kernel sugar content of the used hybrids appeared to be 16.1 to 13.0Brix(%). Especially, CNU08H-15, CNU08H-35 and CNU08H-h39 hybrids were highly appeared as 15 above. Pericarp thickness of check hybrid, Yeonongchal, was thicker as 46.0㎛, while that of CNU08H-39 compared to other hybrids showed the thinnest as 23.0㎛. From this study, we could obtain several superior colored hybrids with thinner pericarp and high sugar contents like CNU 08-39 and CNU 08-h121 hybrids. Accordingly, these hybrids will be apply as new developed variety through confirmed trials.

Barley Yellow Mosaic Virus (BaYMV) caused significant reduction in barley yield and is difficult to control due to alive parasitic soil-borne fungus, Palmyra gamines that transmits the, virus. Previous studies have indicated that a virus-free soil could be infested by using virus-contaminated farming machineneries and implements. For the further confirmation of this finding, different proportions of BaYMV-infested soil were mixed into virus free soil. Three barley varieties (Hordum vulgarae, cv "Olbori", "Baegdong" and "Sacheon 6") were sown in pots treated with different rate of P. graminis-infested soil ranging from 0% to 100% in October 20, 2001. Results showed that BaYMV infection increased as the rate of infested soil increased. Initial symptoms were observed in a pots treated with 10% infested soil in all the 3 varieties of barley. "Olbori" had about 5% infection in 20% infested soil and about 10% infection in 40% or 50% infested soil and about 20% infection in 60% infested soil. In "Baegdong", the trend of BYMV occurrence was similar with "Olbori" but the time of severe infection was earlier than "Olbori". BaYMV infection in "Sacheon 6" was even earlier than "Baegdong" with much more severe symptoms than "Baegdong". The growth rate of barley was affected by about 19-22% when grown in 20% infested soil. As the rate of BaYMV infested soil increased the heading date was delayed but the maturing date was early in "Olbori" and "Sacheon 6". Also, reduction rate of culm length in 3 varieties increased with increase of infested soil content. However, "Olbori" showed the highest reduction. "Sacheon 6", have been characterized with long spike length, however was significantly reduced as the infested soil increased. On the other hand, spike length of "Olbori" was not significantly affected despite of increased of infested soil. The reduction rate of 1000 kernel weight was higher in large kernel size cultivar "Sacheon 6" and "Olbori" than small kernel size "Baegdong" as increase of BaYMV-infested soil content.
