The effect of interactions among mu- and delta-opioid receptors, especially the putative delta(1)- and delta(2)-opioid receptors, in the nucleus accumbens on accumbal dopamine release was investigated in awake rats by in vivo brain microdialysis. In agreement with previous studies, perfusion of the nucleus accumbens with the mu-, delta(1)- and(More)
The effects of the mu-receptor agonist fentanyl on extracellular levels of dopamine in rat nucleus accumbens were studied in awake animals by in vivo brain microdialysis. Fentanyl dose-dependently increased the levels of dopamine when given intravenously (microg/kg) or via a microdialysis probe placed into the ventral tegmental area or the nucleus accumbens(More)
Rats received haloperidol (1.0 mg/kg i.p.) or clozapine (10 mg/kg i.p.), twice daily for 4 weeks: vacuous chewing--recorded 26 h after the final injection--similarly increased in both groups. Three h later, the rats were challenged with dopaminomimetics, and automatically recorded jaw movements were analysed. Both apomorphine and a mixture of D1 and D2(More)
The effects of sesamin, a lignan from sesame oil, on various aspects of cholesterol metabolism were examined in rats maintained on various dietary regimens. When given at a dietary level of 0.5% for 4 weeks, sesamin reduced the concentration of serum and liver cholesterol significantly irrespective of the presence or absence of cholesterol in the diet,(More)

It focuses on the development of the ICT industry, particularly the cultural aspects of the ICT boom. for their comments and insights. We also thank many colleagues at the World Bank, the Asian Study Group, and George Washington University for the opportunity to exchange ideas and develop ideas as well their comments. In particular, we are grateful to(More)
The effects of propofol, a hydrophobic intravenous anaesthetic, and fentanyl, an opiate analgesic, on extracellular concentrations of gamma-aminobutyric acid (GABA) in the nucleus accumbens of rats were studied using in vivo brain microdialysis. The concentrations of GABA in the microdialysate of the nucleus accumbens reached a stable baseline value(More)
This paper estimates new Keynesian, dynamic stochastic general equilibrium models in a liquidity trap (the non-negativity constraint on short term nominal interest rates) using the Monte Carlo particle filter, proposed by Kitagawa (1996) and Gordon et al. (1993), and a self-organizing state space model, proposed by Kitagawa (1998). In our method, we(More)
The present study examined whether the shell and the core of the nucleus accumbens play a differential role in the display of YM-14673-induced jaw movements in rats. For that purpose the effects of YM-14673 were compared to those of a SKF 82958 and quinpirole combination, a dopamine D1 and a D2 receptor agonist respectively, that is known to functionally(More)
