BACKGROUND It was reported that expansive pedicle screw (EPS) and polymethylmethacrylate-augmented pedicle screw (PMMA-PS) could be used to increase screw stability in osteoporosis. However, there are no studies comparing the two kinds of screws in vivo. Thus, we aimed to compare biomechanical and interfacial performances of EPS and PMMA-PS in osteoporotic(More)
OBJECTIVE To investigate the effect of Vitamin E (VitE) on memory and brain monoaminergic neurotransmitter level in chronic episodic hypoxia (EHYP) rat. METHODS VitE [50 IU/ (250 g.d) or 5 IU/ (250 g.d)] was given to the EHYP rat model. The memory was evaluated by the passive avoidance test and the levels of monoaminergic neurotransmitter, including(More)
Technical repeat experiments showed biological variations contribute to the cell-to-cell variation Theoretically, comparison of Pico-Seq data from two cells with exactly the same chromatin status should be used to accurately estimate the technical noise between single cell libraries. To obtain two " identical " cells, we sorted two NIH3T3 cells into one(More)
