[Evaluation of hypertensive patients by radial arterial diameter variation recording].

A blood less analysis technique of the diameter variation signal at radial artery was used to evaluate the arterial disease and the cardiovascular risk in hypertensive patients. A movement transducer was used to record the wrist pulse. A radial augmentation index was proposed to quantify the magnitude of the pressure wave reflections in the aortic region.

[Incorporation of squid oil fatty acids to plasma lipoproteins in rats].

There is clinical and epidemiologic evidence that long chain polyunsaturated fatty acids of the n-3 series, (AGPI n-3): eicosapentaenoic acid (EPA 20:5 n-3) and docosahexaenoic acid (22:6 n-3) decrease the incidence of heart attack, coronary restenosis and also platelet aggregation, leukotriene synthesis and arterial pressure. They also decrease significantly the severity of atherosclerosis in hyperlipidemic models. Some of these results are obtained after daily intake of 3g or more of AGPI n-3.
