[Diagnostic value of serum myoglobin]. / Valore diagnostico della mioglobina serica.

Radioimmunological determination of serum myoglobin in 115 patients is reported. Frankly pathological values were noted in 45/55 subjects with a diagnosis of acute myocardial infarct, whereas 7 displayed only a slight rise, and the remaining 3 proved to be false negatives. Pathological values were observed only 2 hr after the commencement of pain, with maxima after 6-20 hr (mean 10 hr). Values returned tonormal 37 hr after the onset of pain. In patients with angina pectoris, myocardial ischaemia, and pulmonary oedema not due to acute infarct, there was only a slight increase in serum levels, while pathological values were never noted in patients with precordial pain of non-cardiac origin.

Head rotation trajectories compared with eye saccades by main sequence relationships.

A helmet apparatus permitted duration, peak velocity, and peak acceleration measurements as functions of magnitude of horizontal head rotation; these "main sequence" data give evidence for multipulse-step neurological signals appropriate for time optimal control of head rotation similar to those of saccadic eye movements.
