Rapid eye movement sleep deprivation is reported to increase Na+,K+-ATPase activity. This increase was shown earlier to be stimulated by norepinephrine acting on alpha1-adrenoceptor. The involvement of a subtype of alpha1-adrenoceptor and the possible molecular mechanism of action of norepinephrine in increasing the enzyme activity were investigated using(More)
Rapid eye movement (REM) sleep deprivation elevates noradrenaline level, which upon acting on alpha1-adrenoceptors increases Na-K-ATPase activity; however, the detailed intracellular mechanism of action was unknown. Since membrane integrity is crucial for maintaining Na-K-ATPase activity as well as ionic exchange and noradrenaline affects membrane(More)
Sleep and wakefulness are instinctive behaviours that are present across the animal species. Rapid eye movement (REM) sleep is a unique biological phenomenon expressed during sleep. It evolved about 300 million years ago and is noticed in the more evolved animal species. Although it has been objectively identified in its present characteristic form about(More)
Isolated studies showed that norepinephrinergic REM-OFF neurons are active throughout except during rapid eye movement (REM) sleep when they are inhibited possibly by GABA. Similarly, independent studies have also reported that during REM sleep deprivation those REM-OFF neurons continue firing, that there is increased norepinephrine (NE) in the brain and(More)
It has been shown that rapid eye movement (REM) sleep deprivation increases Na-K ATPase activity. Based on kinetic study, it was proposed that increased activity was due to enhanced turnover of enzyme molecules. To test this, anti-alpha1 Na-K ATPase monoclonal antibody (mAb 9A7) was used to label Na-K ATPase molecules. These labeled enzymes were quantified(More)
We successfully developed a single-step detection and removal unit for Bi(III) ions based on dithizone (DZ) anchored on mesoporous TiO2 with rapid colorometric response and high selectivity for the first time. [(DZ)3-Bi] complex is easily separated and collected by mesoporous TiO2 as adsorbent and preconcentrator without any color change of the produced(More)
