Serotonin-promoting drugs show cardioprotective properties in patients with anxiety or depression, but it is not known if this is a direct effect of increasing serotonin. We aimed to characterize the effect of serotonin manipulation through acute tryptophan depletion on cardiovascular and psychological responses to stress challenge in recovered patients(More)
Organ motion can cause artefacts in abdominal imaging particularly with magnetic resonance imaging (MRI), and may often limit the diagnostic quality of an image. If spatial resolution and image quality are to improve in MRI and other imaging techniques, a more detailed understanding of organ motion is required. Despite the importance of organ motion little(More)

We investigated whether association between early adversity and emotional symptoms in young children differs according to variation of the COMT gene. The main outcome measure was the emotionality subscale of the Strengths and Difficulties Questionnaire(More)

We used PET with the non-selective tracer [11C]diprenorphine to examine opioid receptor binding in early abstinence from alcohol dependence and the relationship to craving. We recruited 11 alcohol dependent patients and 13 controls. Subjects underwent one(More)
AIMS The aim of this study was to determine neuropsychological performance in apparently cognitively, mentally, and physically healthy abstinent alcohol-dependent subjects compared with control subjects who were recruited for a number of different neuroimaging studies. METHODS All subjects completed a battery of neuropsychological tests as part of the(More)
This revision of the 2005 British Association for Psychopharmacology guidelines for the evidence-based pharmacological treatment of anxiety disorders provides an update on key steps in diagnosis and clinical management, including recognition, acute treatment, longer-term treatment, combination treatment, and further approaches for patients who have not(More)
