INTRODUCTION Routine blood cultures have been recommended for all patients in treatment guidelines for community-acquired pneumonia (CAP). This practice has become a major area of resource utilisation, despite the lack of evidence in its clinical utility. Calls for abandoning the practice is balanced by the occasions of uncovering an unexpected pathogen or(More)
Epithelial-mesenchymal transition (EMT) is a key process in the tumor metastatic cascade that is characterized by the loss of cell-cell junctions and cell polarity, resulting in the acquisition of migratory and invasive properties. Recent evidence showed that altered microRNA-10b (miR-10b) expression was implicated in the occurrence of EMT of breast cancer.(More)
Aurora-A is an oncogenic serine/threonine kinase, which plays important roles in tumorigenesis, development and chemoresistance of human cancers. The aim of the study was to detect the expression of Aurora-A gene in bladder cancer tissues and analyze its association with prognosis of bladder cancer patients. RT-PCR was performed to detect the expression of(More)

To explore the association between single nucleotide polymorphisms (SNPs) in the promoter region of the inner centromere protein (INCENP) gene and bovine semen quality, the haplotypes in 250 Chinese Holstein bulls were detected using PCR-RFLP method in this study. Two SNPs (g.-556 G>T, rs 136823901 and g.-692 C>T, rs 211010999) and three(More)
