Four cases of silicosis which developed after a relatively short occupational exposure to respirable silica among the members of one family are described. Four young men worked illegally abroad in mining...

Oxytocin (OT) is becoming increasingly established as a prosocial neuropeptide in humans with therapeutic potential in treatment of social, cognitive, and mood disorders. However, the potential of OT as a general facilitator of human learning and empathy is unclear. The current double-blind experiments on healthy adult male volunteers investigated first whether treatment with intranasal OT enha...

The amygdala is believed to play a major role in orienting attention towards threat-related stimuli. However, behavioral studies on amygdala-damaged patients have given inconsistent results-variously reporting decreased, persisted, and increased attention towards threat. Here we aimed to characterize the impact of developmental amygdala damage on emotion perception and the nature and time-cours...

Although the amygdalae play a central role in threat perception and reactions, the direct contributions of the amygdalae to specific aspects of threat perception, from ambiguity resolution to reflexive or deliberate action, remain ill understood in humans. Animal studies show that a detailed understanding requires a focus on the different subnuclei, which is not yet achieved in human research. ...

Punch biopsy specimens obtained from the larynx and sublingual region revealed multi-folded squamous epithelium with a hyperkeratosis pattern and amorphous hyaline material aggregation. This aggregation was also remarkable around the vessels. Histochemical examination showed periodic acid-schiff-posit...

For a long time, it was accepted that calcium and cephalin activate prothrombin. There were secondary questions about the identity of the phosphatide and whether it was important that the phosphatide be bound to protein. Otherwise the issue was closed. Now the basic premise is in sufficient doubt to warrant a restatement of the problem in the light of newer observations. " . . . I have come upo...
