First understand the context and then look at the graph - the effect of attentional guidance on cognitive linear graph processing?

Purpose: Many studies have investigated the effect of signaling on graph processing, but not the effect of a question's timing as attentional guidance (AG). We investigated how the AG, task level, and visual load affect graph processing, among university students.

Design: We developed a graph processing task.

Neurogenic pulmonary edema.

Neurogenic pulmonary edema, although not frequently seen, is extremely important in the differential diagnosis of pulmonary edema. Often the diagnosis is suggested by roentgenogram and clinical history and effective therapy can therefore be instituted.

An unusual angiographic appearance of aorto-iliac disease presenting as the Leriche syndrome.

An unusual angiographic presentation of Leriche syndrome is described that demonstrates short segment occlusions of iliac arteries with bilaterally symmetrical post-stenotic dilatations.

Effects of organic acids on tubulin polymerization and associated guanosine 5'-triphosphate hydrolysis.

We have examined the effects of a number of organic anions, which stabilize tubulin, on tubulin polymerization, associated GTP hydrolysis, and polymer morphology. While microtubule-associated proteins, as well as glycerol, induced formation of typical microtubules in a reaction coupled to GTP hydrolysis at an initial 1:1 stoichiometry, the organic anions had varying effects. Only 2-(N-morpholino)ethanesulfonate induced formation of structures with the morphology of microtubules.
