Osteoarthritis is a degenerative joint disease, in which matrix metalloproteinase (MMP)-13 plays an important role. This study aimed to investigate miRNA-140-mediated negative regulation of MMP-13 expression in interleukin-1β (IL-1β)-stimulated human cartilage cells. The human cartilage cell line C28/I2 was cultured in the presence of IL-1β to mimic an(More)
Porcine circovirus type-2b (PCV2b) is recognized as the etiological agent of the various clinical manifestations of porcine circovirus-associated disease (PCVAD). Previous studies have demonstrated effectiveness of chimeric PCV1-2 vaccines against PCV2b challenge. In this study, the efficacy of inactivated and live-attenuated (2 × 103.5 or 2 × 104.0 50 %(More)
Porcine circovirus type 2 (PCV2) is subdivided into four genotypes: PCV2a, PCV2b, PCV2c and PCV2d. Here, for the first time, we compared the efficacy of two experimental inactivated chimeric PCV1-2 vaccines based on genotypes 2b and 2d. Seventeen 3-week-old pigs were divided randomly into four groups. Group 1 and 2 pigs were inoculated with genotype 2b- and(More)
