In research on event-related potentials (ERP) to emotional pictures, greater attention to emotional than neutral stimuli (i.e., motivated attention) is commonly indexed by two difference waves between emotional and neutral stimuli: the early posterior negativity (EPN) and the late positive potential (LPP). Evidence suggests that if attention is directed(More)
Which emotions are associated with universally recognized non-verbal signals?We address this issue by examining how reliably non-linguistic vocalizations (affect bursts) can convey emotions across cultures. Actors from India, Kenya, Singapore, and USA were instructed to produce vocalizations that would convey nine positive and nine negative emotions to(More)
In recent years, reports have shown positive effects of hyperbaric oxygen (HBO) treatment in posttraumatic circulatory insufficiency of the extremities. A tourniquet model for temporary ischemia was used to examine such treatment in rats. The circulation of the rat hindlimb was interrupted for 3 hours, while the contralateral uninjured leg served as(More)
In 33 severely burned patients, who were followed for two weeks after injury, a transient hypophosphatemia was registered with the decrease in serum phosphate occurring on the second to tenth day after injury. When a previous retrospective study was combined with the present one, there were 50 patients in all. Seven patients died and, of these, five showed(More)
Changes in the calcium- and phosphate homeostasis and its regulating hormones calcitonin (CT) and parathyroid hormone (PTH) are of great importance for several pathophysiological reactions after trauma. In this study calcium, phosphate, CT, PTH and nor-adrenaline, were followed during 14 days after trauma in 20 patients with severe burn injuries. The(More)
Serum phosphate (S-P) and 2,3-diphosphoglycerate (2,3-DPG) were monitored for 10 days after severe burn trauma in 16 patients treated with total parenteral nutrition, including supplementation with 25-75 mmol phosphate daily. Phosphate metabolism was previously shown to be disturbed in patients with severe burns, and hypophosphatemia has been reported to(More)
In traumatic injuries to the extremities, with a circulatory insufficiency, the resultant ischemia leads to decreasing levels of the energy-rich compounds adenosine triphosphate (ATP) and phosphocreatine (PCr) and increasing levels of lactate in muscle. A tourniquet model for temporary ischemia was used to determine if hyperbaric oxygen treatment could(More)
In the post-ischemic muscle, hyperbaric oxygen (HBO) treatments have been shown to reduce post-ischemic edema and enhance aerobic metabolism. In the present paper histological, histochemical and ultrastructural methods were used to study the influences of HBO treatment on the morphology of post-ischemic skeletal muscle. The changes were also quantified(More)
During a 22-month period, 555 consecutive patients at seven hospitals in the western part of Sweden with an acute deep vein thrombosis (DVT) not involving the iliac vein and not having pulmonary embolism were included in a study testing the efficacy of implementing out-patient treatment. For all patients with a confirmed diagnosis of acute DVT, a folder was(More)
The changes in water and electrolyte metabolism associated with severe injury and sepsis are well recognized but changes in tissue content have seldom been available. This report combines the experience obtained from muscle biopsies of such patients performed in two centers; one located in Sweden and one in the U.S. Normal values for muscle water and(More)
