Further observations regarding tuberculin

Further Observations

Initiation and termination of tachycardia was studied by electrical stimulation of the heart in 14 patients with ventricular tachycardia (VT) not related to acute myocardial infarction (group A) and in six patients in whom the tachycardia occurred within 24 hours after the onset of acute myocardial infarction (group B). Results favor re-entry as the mechanism of tachycardia in group A patients....

Vertex Cover: Further Observations and Further Improvements

Recently, there has been increasing interest and progress in lowering the worstcase time complexity for well-known NP-hard problems, particularly for the Vertex Cover problem. In this paper, new properties for the Vertex Cover problem are indicated, and several simple and new techniques are introduced, which lead to an improved algorithm of time O kn + 1 2852 for the problem. Our algorithm also...

Observations Regarding Potential Mechanisms

more complications occurred in six patients (9%), including non-Q wave myocardial infarction (three patients, 4.5%), femoral arterial injury requiring surgical repair (two patients, 3%), and proximal dissection leading to emergency bypass surgery (one patient, 1.5%). Despite these favorable acute results, the 6-month lesion restenosis rate was 30% by life-table analysis. Light microscopy of ret...

Further Studies on the Ophthalmo-tuberculin Reaction in Cattle

Our conclusions differ in a few points from those of our first work on this subject. We are able to sum up our observations in this series of experiments as follows: 1. The ophthalmo-tuberculin test is of limited value in the diagnosis of tuberculosis in cattle. In some cases the reaction is very slight (hyperaemia). In others more pronounced congestion with profuse exudates are noted. Accuracy...
