Experiments were performed to investigate whether adrenal neuronal nitric oxide synthase (nNOS) mRNA and protein expression are responsive to alterations in body volume. Using an RT-PCR technique, the relative quantities of nNOS mRNA as well as the tyrosine hydroxylase and phenylethanolamine N-methyltransferase mRNA in the adrenals of water-deprived rats significantly increased from 12 hr to 4 ...

Sleep supports the formation of a variety of declarative and non-declarative memories, and sleep deprivation often impairs these types of memories. In human subjects, natural sleep either during a nap or overnight leads to long-lasting improvements in visuomotor and fine motor tasks, but rodent models recapitulating these findings have been scarce. Here we present evidence that 5h of acute slee...

This paper uses the recent approach of multidimensional deprivation measures to provide a comprehensive and wide ranging assessment of changes to living standards in India during the period, 1992/93-2004/5.This covers the reforms and the immediate post reforms time periods. The study is based on the simultaneous use of two parallel data sets, namely the NSS and NFHS data sets covering proximate...

Objective: We designed this study to investigate the mechanism of cellular prion protein (PrPC) in memory impairment induced by sleep-deprivation. Methods: Rats were deprived of sleep for 72 h using the modified multiple platform method. The Morris water maze task was used to assess hippocampal-dependent spatial memory. After sleep-deprivation, the rats were sacrificed and their brain tissue wa...

1. The electrolyte and water composition of urine and ileal fluid was studied in six patients with ileostomies during dietary sodium deprivation and at the same time measurements were made of plasma renin activity, plasma aldosterone concentration, renal aldosterone excretion and plasma arginine vasopressin concentration. 2. In each subject there was a reduction in renal sodium excretion within...

AIM The effects of modafinil and amphetamine on sleep-wake cycle and cortical power spectrum were assessed in the cats before and after sleep deprivation. METHODS The sleep deprivation in the cats was used with the water tank technique. Cats were administrated with modafinil (5 mg.kg-1 p.o.) or amphetamine (1 mg.kg-1) before and after sleep deprivation. RESULTS The waking effect of 8-10 h i...
