The study was to investigate the expression and clinical significance of serum microRNAs in prostate cancer. Illumina Human miRNA high-throughput chip was used to detect the serum microRNA expression in prostate tissues from 10 healthy subjects, 30 benign prostatic hyperplasia patients and 75 prostate cancer patients. Moreover, differentially expressed microRNAs were selected for further valida...

We have discovered a ∼1 Hz quasi-periodic oscillation (QPO) in the persistent-emission, the dips, and the type I X-ray bursts of the low-mass X-ray binary 4U 1323–62. The rms amplitude of the QPO is approximately 9%, only weakly depending on photon energy. The amplitude is consistent with being constant throughout the persistent-emission, the dips and the bursts in all but one observation, wher...
