Perplexing peroxisome proliferators.

Soft agarose culture human tumour colony forming assay for drug sensitivity testing: [3H]-Thymidine incorporation vs colony counting Summary In vitro drug sensitivity testing, both by optical colony counting and by a [3H]-TdR incorporation assay, was performed on human tumour cells proliferating in soft agar cultures.

Parsing a perplexing paroxysmal pathway

Introduction Catheter ablation is an effective and often preferred treatment for supraventricular tachycardia (SVT). Successful ablation is predicated on a precise diagnosis of the arrhythmia mechanism. The initial pacing maneuvers during electrophysiologic study (EPS) are often able to narrow the differential diagnosis immediately. We report an unusual case of SVT in which the initial findings...
