RESUMEN

We present a new phenomenon resulting from the interaction of magnetic beads with cancer cells in a laser trap formed on a slide containing a depression 16.5 mm in diameter and 0.78 mm of maximum depth. This phenomenon includes the apparent formation and expansion of a dark bubble that attracts and incinerates surrounding matter when it explodes, which leads to a plasma emitting intense radiation that has the appearance of a star on a microscopic scale. We have observed the star-like phenomenon for more than 4 years, and the intensity depends on the laser's power. Measuring the laser power of the dark bubble shows the entrapment of electromagnetic energy as it expands.

RESUMEN

The ouabain-sensitive 42K+ flux from an artificial medium into erythrocytes was measured in 29 control subjects, 66 patients with chronic parenchymatous renal disease and in 32 subjects with primary hypertension. The ouabain-sensitive 42K+ influx was reduced in subjects with chronic renal disease by about 20%, even when they were normotensive. The reduction in these patients was greater than that in patients with essential hypertension. The changes in 42K+ influx and Na+ content with a decrease in the 42K+ influx/Na+ content ratio suggest an inhibition of the Na+ pump in the patients with chronic renal disease. The inhibition of the Na+ pump may be secondary to the hypervolaemia which we suggest is the initial event leading to renal hypertension.
