objective(s) cannabinoids have been implicated in memory deficit. we examined the effect of am281, cannabinoid antagonist/inverse agonist in prevention of scopolamine-induced cognitive deficit. materials and methods  object recognition task was used to evaluate memory in mice. exploration time in the first and the second trial was recorded. the differences in exploration between a previously se...

conclusions this preliminary assessment suggests that duloxetine may be a medication of interest in the treatment of children with adhd. further controlled studies with larger samples are required to evaluate the efficacy of duloxetine in treatment of children with adhd. results ten children with a mean age of 8.40 ± 1.67 years terminated the trial. a significant reduction in cprs-r and its sub...

HIGHLIGHTS Azospirillum brasilense stimulates root growth in maize under water deficit. Maize inoculated with A. shows greater photosynthesis drought conditions. Under deficit, plants showed use efficiency (WUE).

OBJECTIVE To determine whether nitric oxide production levels differ in patients with deficit and non-deficit forms of schizophrenia. METHODS We investigated plasma nitrate levels, an index of in vivo nitric oxide production, in patients with deficit syndrome (n = 11) and non-deficit syndrome (n = 14) and healthy controls (n = 12) with a combination of high-performance liquid chromatography a...

A number of authors have made the claim that dyslexia is the result of a deficit in the magnocellular part of the visual system. Most of the evidence cited in support of this claim is from contrast sensitivity studies. The present review surveys this evidence. The result of this survey shows that the support for the magnocellular deficit theory is equivocal. In the case of spatial contrast sens...

Findings on neuropsychological associates of the negative syndrome of schizophrenia have been inconsistent. The "deficit syndrome," a reconceptualization of the negative syndrome, was developed in part to address this inconsistency. The purpose of this study was (1) to replicate previous findings relating the deficit syndrome to impairment of certain kinds of attentional abilities, and (2) to c...

To understand how temperate coexisting tree species respond to water deficit, the seedlings of two coexisting species, Phellodendron amurense Rupr. And Fraxinus mandshurica Rupr., were transplanted into plastic flowerpots. Three water deficit treatments were used, W1 (60-90% field moisture capacity), W2 (40-60% field moisture capacity), and naturally occurring precipitation (CK), with the aim o...
