Results of both experiments revealed effects of orientation, side and view on reaction time, click here but an effect of stimulus thumb posture occurred only in the second experiment in which participants’ thumbs were fixed. In palmar view, stimuli rotated by 90 degrees with fingers pointing towards the participant’s midline had shorter reaction times than stimuli rotated (evidentially less comfortably) in the opposite direction. This finding suggests that participants applied motor imagery strategies for palmar but not for dorsal views of the hand,

indicating a difference in visual and sensorimotor familiarity. (C) 2012 Elsevier Ireland Ltd. All rights reserved.”
“The glucocorticoid (GC) hormone cortisol is the end product of the hypothalamic-pituitary-adrenal axis (HPA axis). Acute psychological stress increases HPA activity and GC release. In humans, chronic disturbances in HPA activity have been observed in affective disorders and in addictive behaviour. Recent research indicates that acute effects of GCs may be anxiolytic and increase reward sensitivity. Furthermore, cortisol acutely influences early cognitive processing of emotional stimuli.

In order

to extend such findings to more complex emotional-cognitive behaviour, the present study tested acute effects of 40 mg cortisol on motivated decision making in 30 healthy young men.

Results showed that cortisol indeed increased risky decision making, as predicted. This effect occurred for decisions

where making a risky choice could potentially yield a big reward. These results are discussed with respect to currently proposed mechanisms for cortisol’s potential learn more anxiolytic effect and GCs’ involvement in reward systems.”
“Objective: This review was performed to analyze the current knowledge and controversies in the pathophysiology, diagnosis, treatment, and outcomes of pediatric venous thromboembolism (VTE) compared with adults.

Methods: Searches of the MEDLINE database and manual searches of the references of selected articles were performed to select reports for their relevance and quality of information on the similarities and differences in pathophysiology, diagnosis, and treatment Protein kinase N1 of VTE in children and adults.

Results: Symptomatic VTE incidence is reported at a rate of 0.07 in every 10,000 children, which is significantly lower than the rate in adults. Pulmonary emboli in adolescents are rarely fatal, unlike in adults. VTE recurrence is also much lower in children. Young age has been shown to be protective of VTE, whereas central venous catheters are very important in pediatric venous thrombosis. The incidence of postthrombotic syndrome varies from 20% to 65%, with mild symptoms in most children. Cerebral and visceral vein thrombosis may lead to severe morbidity and death. Some factors of thrombophilia have a significant effect in the pediatric population; however, its overall significance is controversial.
