Development and Application of a TaqMan RT-qPCR for the Detection of Foot-and-Mouth Disease Virus in Pigs.

The global livestock industry is facing a serious threat from a widespread foot-and-mouth disease virus (FMDV) epidemic. The timely detection of FMDV can significantly mitigate its harmful effects. This study aimed to establish and evaluate a TaqMan fluorescence quantitative PCR assay to assess its sensitivity, specificity, reproducibility, and stability.

Simple and rapid identification of beef within 30 min using a new food nucleic acid release agent combined with direct-fast qPCR.

Simple and rapid molecular detection technologies for authenticating animal species are urgently needed for food safety and authenticity. This study established a new direct-fast quantitative polymerase chain reaction (qPCR) detection technology for beef to achieve rapid and on-site nucleic acid detection in food. This technology can complete nucleic acid extraction in 4 min using a new type of food nucleic acid-releasing agent, followed by direct amplification of the DNA sample by fast qPCR in 25 min.

miR-365 functions as a tumor suppressor by directly targeting CYR61 in osteosarcoma.

Increasing evidence indicates that microRNAs(miRNAs) are often aberrantly expressed in osteosarcoma (OS) and play critical roles in OS tumorigenesis. Therefore, the discovery of miRNAs may provide a new and powerful tool for understanding the mechanismof OS initiation and development. The aim of this study was to investigate the functional significance of miR-365 and identify its possible mechanism in OS cells.
