This article compares search effectiveness when using query-based Internet search (via the Google search engine), directory-based search (via Yahoo) and phrase-based query reformulation assisted search (via the Hyperindex browser) by means of a controlled, user-based experimental study. The focus was to evaluate aspects of the search process. Cognitive load(More)
BACKGROUND Reboxetine is a potent antidepressant, with efficacy comparable to that of imipramine, desipramine, and fluoxetine, and has improved side-effect profile. The basis of its efficacy and improved tolerability is sought through studies of reboxetine in a number of pharmacological models of depression. METHODS Pharmacological selectivity for uptake(More)
The effect of additional dietary trans fatty acids (7% energy) on plasma lipids was assessed in a double-blind comparison of four separate diets: 1, enriched with butter fat (lauric-myristic-palmitic); 2, oleic acid-rich; 3, elaidic acid-rich; 4, palmitic acid-rich. The total dietary period was 11 weeks and comprised normal foods plus specific fat(More)
Over the course of the last 50 years many models of major depressive disorder have been developed on the basis of theoretical aspects of this disorder. These models and procedures have been crucial in the discovery and development of clinically-effective drugs. Notwithstanding, there is presently great concern about the discrepancy between positive outcomes(More)

The limited effect of AChE inhibitors and NMDA receptor antagonists for the treatment of the cognitive symptoms of Alzheimer's disease has prompted the search for new drugs that are capable not only of treating behavioral symptoms, but also of modifying the disease process. Considerable research efforts have been focused on orthosteric muscarinic M1(More)
PNU-151774E [(S)-(+)-2-(4-(3-fluorobenzyloxy) benzylamino) propanamide, methanesulfonate] is a structurally novel anticonvulsant having Na+ channel-blocking and glutamate release-inhibiting properties, as well as being a MAOB inhibitor. Its anticonvulsant activity was evaluated in the maximal electroshock (MES) test and in chemically induced seizures(More)
This paper is about finding explicit and implicit connections between people by mining semantic associations from their email communications. Following from a socio-cognitive stance, we propose a model called HALe which automatically derives dimensional representations of words in a high dimensional context space from an email corpus. These dimensional(More)
Both 5-HT1A and 5-HT2A receptors have been implicated in modulating ethanol self-administration. A novel serotonergic compound, FG 5974, with combined 5-HT1A agonist/5-HT2A antagonist activities, has shown effects in decreasing ethanol consumption in two-bottle choice paradigms. In the present study, the effect of this compound on operant responding for(More)
