Potassium chloride supplementation diminishes platelet reactivity in humans.

The prevalence of occlusive stroke is inversely correlated with potassium intake. We explored the hypothesis that a high potassium intake attenuates platelet reactivity, as expressed in ADP-evoked platelet aggregation. We studied healthy men (n=31) and women (n=42), blacks (n=33) and whites (n=40).

Telomere length in the newborn.

Telomere length is similar in different organs of the human fetus but variable among fetuses. During extrauterine life telomere length is highly variable among individuals and longer in women than men. In the present work we addressed the following questions: 1) Are there sex-related differences in telomere length at birth? 2) Is there synchrony (i.
