Burn-specific pain anxiety and sleep disorders are common factors in burned patients that affect wound healing process, as well as the severity of burn pain. This study aimed to investigate the effect of foot reflexology massage on burn-specific pain anxiety and sleep condition of patients hospitalized in the burn ICU. In this randomized controlled clinical trial, 52 patients were assigned by permuted block randomization 11 to the intervention (n=26) and control (n=26) groups. The intervention group received 20min of foot reflexology massage during 3 days on their third, fourth and fifth days of hospitalization and 15min before changing wound dressings. Patients in the control group merely received routine care. The Burn-Specific Pain Anxiety Scale (BSPAS) was completed for three consecutive days before and after changing wound dressings, and St. Mary's Hospital Sleep Questionnaire (SMHSQ) was filled out for four consecutive days before changing wound dressings for patients in both groups. The data were aregistration code IRCT20110906007494N27). Based on the results, foot reflexology massage can effectively reduce pain anxiety levels and improve sleep quality and quantity of patients with burn injuries; therefore, this non- pharmacological therapeutic method is recommended to be used in the burn ICUs. (Clinical trial's registration code IRCT20110906007494N27).Through pharmacological manipulation of the serotonergic (5-Hydroxytryptamin, 5-HT) system, combined with behavioral analysis, we tested the hypothesis that fear responses to predictable and unpredictable threat are regulated through stimulation of 5-HT receptors (5-HT-R) in the anterodorsal section of the bed nucleus of the stria terminalis (adBNST). Local adBNST application of 5-HT1A-R antagonist WAY100635 and 5-HT1B-R antagonist NAS-181 before fear retrieval enhanced freezing, 24 h after predictable fear conditioning. In contrast, increased fear responses to unpredictable threat were blocked by 5-HT1A-R agonist Buspirone (given before conditioning or retrieval) and 5-HT1B-R agonist CP-94253 (applied before training). Prolonged fear responses were also blocked by local application of the 5-HT2A-R antagonist R-96544 before fear retrieval, and conversely, local application of the 5-HT2A-R agonist NBOH-2C-CN hydrochloride before fear retrieval enhanced freezing 24 h after predictable conditioning, indicating augmented fear responses. Activation of inhibitory 5-HT1A- or 5-HT1B-Rs and the blockade of the excitatory 5-HT2A-R before unpredictable fear conditioning significantly reduced freezing during retrieval. The results from this study suggest that modulation of inhibitory 5-HT1A/1B-R and/or excitatory 5-HT2A-R activity in the adBNST may represent potential targets for the development of new treatment strategies in anxiety disorders. In addition, this study supports the validity and reliability of the mouse model of modulated fear to predictable and unpredictable threats to study mechanisms of fear and anxiety in combination with pharmacological manipulations.The quantification of myocardial perfusion with contrast agent (CA) tracers requires the precise knowledge of the arterial input function (AIF). In this study a method for MR-guided vascular interventions is evaluated that determines the AIF via an active tracking catheter during targeted CA injection. A phantom experiment with a dialysis filter was conducted to measure the AIF using an active catheter and a dynamic image series as reference. To compensate for dilution and coil sensitivity effects, correction methods were developed for the catheter-based AIF determination. From the dynamic MR measurements in the perfusion phantom quantitative perfusion maps were calculated by a deconvolution of the measured CA concentration with the AIF, and additional flow measurements were used to normalize the perfusion map.
