Introduction: The GABAergic system of the brain plays a key role in morphine tolerance and sensitization. As isoniazid is a modulator of the GABAergic system, the present study aims to understand whether isoniazid can influence the induction of tolerance and sensitization to the rewarding effects of morphine.  Methods: The rewarding effects of morphine and isoniazid were assessed using a Condi...

BACKGROUND Discrepancy between preferred and actual place of death is common in cancer patients. While previous research has elucidated the factors associated with congruence between patients' preferred and actual place of death, it is not known how the perspective of the family influences the place of death. This study examined whether family preference for place of death mediates the relation...

The rewarding effects of nicotine contribute to the chronic use of tobacco products. The place conditioning task, a widely used pre-clinical model to study drug reward, has lead to mixed results in rats when nicotine was administered subcutaneously or intraperitoneally; intravenously administered nicotine has not been examined. Further, much of the research demonstrating a nicotine-conditioned ...

The motivational effects of nicotine were examined in mice using an unbiased place conditioning design. Swiss-Webster mice received four 15-min parings of a tactile stimulus with different doses of nicotine (0.25-2.0 mg/kg, IP). A different tactile stimulus was paired with saline injections. During conditioning, nicotine produced locomotor depression at the 2.0-mg/kg dose, with the greatest red...
