a b s t r a c tintroduction: craving to methamphetamine is a significant health concern and exposure to methamphetamine cues in laboratory can induce craving. in this study, a task designing procedure for evaluating methamphetamine cue-induced craving in laboratory conditions is examined. methods: first a series of visual cues which could induce craving was identified by 5 discussion sessions b...
In the Theory of Challenge and Threat States in Athletes (TCTSA) it is proposed that on approach to motivated performance situations an individual can respond in a challenge state or a threat state. Challenge and threat states are marked by contrasting patterns of psychological, emotional, and cardiovascular (CV) responses. A challenge state is proposed to maintain or facilitate performance com...
This article gives an overview of recently published literature on the factors that govern SN2 reactivity. By comparing reactivity in solution with that in the isolated gas phase, it has become possible to dissect the contribution of the solvent from that of the intrinsic molecular properties. This has proven to be an extremely important and fruitful step forward in obtaining key knowledge not ...
Drugs-of-abuse may increase the salience of drug cues by sensitizing the dopaminergic (DA) system (Robinson and Berridge, 1993), leading to differential attention to smoking stimuli. Event-related potentials (ERPs) have been used to assess attention to smoking cues but not using an ERP component associated with DA-mediated salience evaluation. In this study the DA-related P2a and the P3, were c...

2014 Femtosecond optical techniques allowing the generation of intense optical pulses from the near ultraviolet to the near infrared are used in the monitoring of ultrafast photophysical and photochemical reactions in aqueous solutions. Selected examples for dynamics of electron solvation in water and aqueous solution of ferrocyanide are discussed. Revue Phys. Appl. 22 (1987) -1759 DÉCEMBRE 198...
