  1. Park H, Jung S, Shin H, Ha S, Park T, Park J, et al. Localization and persistence of hepatitis A virus in artificially contaminated oysters. Int J Food Microbiol. 2019;299:58-63 pubmed publisher
    ..HAV was detected in the stomach, intestine, and gills by only ISH. The distribution of HAV in various oyster tissues may explain the persistence of contamination in oysters during the depuration process. ..
  2. Lee M, Seo D, Seo J, Oh H, Jeon S, Ha S, et al. Detection of viable murine norovirus using the plaque assay and propidium-monoazide-combined real-time reverse transcription-polymerase chain reaction. J Virol Methods. 2015;221:57-61 pubmed publisher
    ..The results of EMA-combined qRT-PCR were similar to those of qRT-PCR. Thus, PMA-combined qRT-PCR correlated well with the plaque assay in detecting viable MNVs. ..
  3. Lee W, Seo D, Oh H, Jeon S, Jung D, Choi C. Simultaneous Detection and Prevalence of Allergens in Anisakis Species Isolated from Marine Fishes. J Food Prot. 2016;79:789-94 pubmed publisher
    ..7% of A. pegreffii carried both Ani s 4 and Ani s 5, which are heat-resistant allergens. Fifty-two to 65% of A. pegreffii isolated from S. japonicus and C. myriaster carried all five Ani s allergens. ..
  4. Seo D, Choi C. Inhibition of Murine Norovirus and Feline Calicivirus by Edible Herbal Extracts. Food Environ Virol. 2017;9:35-44 pubmed publisher
    ..24 ± 4.12%. The seven herbal extracts of C. sinensis, F. carica, P. multiflorus, A. japonica, I. obliquus, C. pinnatifida, and C. sativum may have the potential to control noroviruses without cytotoxicity. ..
  5. Seo D, Choi S, Jeon S, Jeong S, Park H, Lee B, et al. Comparative sequence analysis of enteroaggregative Escherichia coli heat-stable enterotoxin 1 identified in Korean and Japanese Escherichia coli strains. Int J Food Microbiol. 2017;243:1-8 pubmed publisher
    ..Compared with the non-diarrheal isolates, clonal diversity and sequence variations of the astA gene in outbreak isolates may be associated with virulence potential of EAST1. ..
  6. Oh H, Seo D, Jeon S, Park H, Jeong S, Chun H, et al. Isolation and Characterization of Bacillus cereus Bacteriophages from Foods and Soil. Food Environ Virol. 2017;9:260-269 pubmed publisher
    ..cereus in vitro within 1 h. Therefore, they are considered potential candidates for controlling the contamination of B. cereus in food or other applications. ..
  7. Seo D, Choi C. Inhibitory mechanism of five natural flavonoids against murine norovirus. Phytomedicine. 2017;30:59-66 pubmed publisher
    ..Pre-treatment of RAW 264.7 cells with the five flavonoids inhibited MNoV by upregulating the expression of antiviral cytokines (IFN-?, IFN-?, and TNF-?) and interferon-stimulating genes (Mx and ZAP). ..
  8. Kang J, Song K, Jeong K, Kim S, Choi C, Lee C, et al. Involvement of Cox-2 in the metastatic potential of chemotherapy-resistant breast cancer cells. BMC Cancer. 2011;11:334 pubmed publisher
    ..Therefore, not only Cox-2 but also EP1 and EP3 could be important targets for chemosensitization and inhibition of metastasis in breast cancers that are resistant to chemotherapy. ..
