Retrograde and anterograde object-recognition memory was assessed in rats with cytotoxic lesions of the hippocampal formation (HPC), using a paradigm based on the natural tendency of rats to spend more time exploring novel objects than familiar objects. The rats were allowed to explore a sample object for 5 min/day on 5 consecutive days, either 5 weeks or 1(More)
Although it is well established that methadone can be an effective treatment for opiate addiction, it is not clear how methadone maintenance affects cocaine use and cravings in individuals who self-administer both opiates and cocaine. In our attempt to explore the effect of methadone maintenance on the effects of cocaine, we first assessed the locomotor(More)
Although several studies in rats have found that hippocampal damage has negligible effects on anterograde object-recognition memory, the findings are not entirely conclusive, because most studies have used retention intervals lasting only a few hours. We assessed the effects of neurotoxic hippocampal lesions on anterograde object recognition, using a(More)
We conducted a systematic examination of the experience of delirium in a sample of 154 hospitalized patients with cancer. Patients all met DSM-IV criteria for delirium and were rated with the Memorial Delirium Assessment Scale as a measure of delirium severity, phenomenology, and resolution. Of the 154 patients assessed, 101 had complete resolution of their(More)
Estrogen-related receptor a (ERRa) and proliferator-activated receptor g coactivator-1a (PGC-1a) play central roles in the transcriptional control of energy homeostasis, but little is known about factors regulating their activity. Here we identified the homeobox protein prospero-related homeobox 1 (Prox1) as one such factor. Prox1 interacts with ERRa and(More)
We conducted an open, prospective trial of olanzapine for the treatment of delirium in a sample of 79 hospitalized cancer patients. Patients all met DSM-IV criteria for a diagnosis of delirium and were rated systematically with the Memorial Delirium Assessment Scale (MDAS) as a measure of delirium severity, phenomenology, and resolution, over the course of(More)
Previous research showed that handwriting production is mediated by linguistically oriented processing units such as syllables and graphemes. The goal of this study was to investigate whether French adults also activate another kind of unit that is more related to semantics than phonology, namely morphemes. Experiment 1 revealed that letter duration and(More)
Psychoactive medications are often reported as delirium risk factors in hospitalized patients, and delirium induced by medication is potentially avoidable. The authors critically reviewed the evidence for a role of medications in delirium etiology. Only a few positive associations were noted. Use of psychoactive medications, considered together as a single(More)
The purpose of this pilot study was to investigate the efficacy of in-home telerehabilitation for people with Chronic Obstructive Pulmonary Disease (COPD). Three community-living elders with COPD were recruited in a rehabilitation outpatient group and by direct referrals from pneumologists with outpatients who have COPD. A pre/post-test design without a(More)
