Research on human embryonic stem cells (hESCs) has attracted much attention given their great potential for tissue regenerative therapy and fundamental developmental biology studies. Yet, there is still limited understanding of how mechanical signals in the local cellular microenvironment of hESCs regulate their fate decisions. Here, we applied a(More)
Magnetic field induced antiferromagnetic phase of the underdoped cuprates is studied within the t − t ′ − J model. A magnetic field suppresses the pairing amplitude, which in turn may induce antiferromagnetism. We apply our theory to interpret the recently reported quantum oscillations in high magnetic field in ortho-II YBa2Cu3O6.5 [1] and propose that the(More)
Systematic protein expression studies in the brain of exercising and sedentary animals have not been carried out so far and it was therefore decided to determine differences in metabolic protein levels in rat hippocampus of sedentary, voluntary and involuntary exercising rats by a proteomic approach. Aged, male Sprague-Dawley rats, 23 months old, were used(More)
There is evidence to suggest that low levels of magnesium (Mg) are associated with affective disorders, however, causality and central neurobiological mechanisms of this link are largely unproven. We have recently shown that mice fed a low Mg-containing diet (10% of daily requirement) display enhanced depression-like behavior sensitive to chronic(More)
The Multiple T-maze (MTM) and the Barnes maze (BM) are land mazes used for the evaluation of spatial memory. The observation that mice are performing differently in individual mazes made us test the hypothesis that differences in cognitive performances in the two land mazes would be accompanied by differences in hippocampal protein levels. C57BL/6J mice(More)
Previous studies showed that TNF-α could activate voltage-gated Na+ channels (VGSCs) in the peripheral nervous system (PNS). Since TNF-α is implicated in many central nervous system (CNS) diseases, we examined potential effects of TNF-α on VGSCs in the CNS. Effects of TNF-α (1–1000 pg/mL, for 4–48 h) on VGSC currents were examined using whole-cell voltage(More)
This study was conducted to explore the modulation of GTPs on cognitive performances in psychological stress rats. Wistar rats were randomly assigned to five groups as follows: control group, stress group, and three stress groups with low, medium and high-doses of GTPs modulation respectively. The changes of cognitive performances were examined by(More)
Chloride channel-3 (ClC-3) is suggested to be a component and/or a regulator of the volume-activated Cl− channel in the plasma membrane. However, ClC-3 is predominantly located inside cells and the role of intracellular ClC-3 in tumor growth is unknown. In this study, we found that the subcellular distribution of endogenous ClC-3 varied in a cell(More)
Prolonged exposure to volatile anesthetics, such as isoflurane and sevoflurane, causes neurodegeneration in the developing animal brains. Recent studies showed that dexmedetomidine, a selective α2-adrenergic agonist, reduced isoflurane-induced cognitive impairment and neuroapoptosis. However, the mechanisms for the effect are not completely clear. Thus, we(More)
Antidepressant-related protein (NDRG2) is a member of the N-myc downstream-regulated gene family and a role for differentiation and signaling has been proposed. Performing protein profiling we observed NDRG2 and decided to characterize this important biomolecule. Estrous cycle phases were determined in Sprague-Dawley rats and the hippocampus was taken.(More)
