This brief deals with the problem of stability analysis for a class of recurrent neural networks (RNNs) with a time-varying delay in a range. Both delay-independent and delay-dependent conditions are derived. For the former, an augmented Lyapunov functional is constructed and the derivative of the state is retained. Since the obtained criterion realizes the(More)
A growing body of evidence supports the argument that bone marrow-derived mesenchymal stem cells (MSCs) can differentiate into cardiomyocyte-like cells in an appropriate cellular environment, but the differentiation rate is low. A cocktail method was designed: we investigated the role of 5-azacytidine (5-aza), salvianolic acid B (SalB), and cardiomyocyte(More)
BACKGROUND Breast milk expression (breast pumping) has become prevalent as an important dimension of breastfeeding behavior. It is, however, not clear whether increasing breast milk expression contributes to extend the duration of breastfeeding. The objective of the present study was to evaluate the impact of breast milk expression in early postpartum(More)
BACKGROUND INFORMATION Although adult bone-marrow-derived cell populations have been used to make teeth when recombined with embryonic oral epithelium, the differences between dental and non-dental stem-cell-mediated odontogenesis remain an open question. RESULTS STRO-1(+) (stromal precursor cell marker) DPSCs (dental pulp stem cells) and BMSSCs (bone(More)
To explore the mechanism(s) of exercise training on ovariectomized (OVX)-induced liver lipid disorder, we observed effects of treadmill training on liver fat accumulation and ERalpha expression in intact and ovariectomized rats. Sixty female rats were randomly assigned to six groups: Sham sedentary (S-S), Sham exercised (S-EX), ovariectomized sedentary(More)
Size-controlled Ag0.04@Co0.48@Ni0.48 core-shell nanoparticles (NPs) were synthesized by employing graphene (rGO) with different reduction degrees as supports. The number of C=O and C=O functional groups on the surface of rGO might play a major role in controlling the particle size. The strong steric-hindrance effect of C=O resulted in the growth of large(More)
