Missing mass in collisional debris from galaxies.

Recycled dwarf galaxies can form in the collisional debris of massive galaxies. Theoretical models predict that, contrary to classical galaxies, these recycled galaxies should be free of nonbaryonic dark matter. By analyzing the observed gas kinematics of such recycled galaxies with the help of a numerical model, we demonstrate that they do contain a massive dark component amounting to about twice the visible matter.

Endermologie: humoral repercussions and estrogen interaction.

Endermologie is a motorized rhythmic folding-unfolding and suction technique of the panniculus adiposus. Our study shows that one 40-min Endermologie session produces no noticeable changes in biological parameters, except for plasma estradiol levels, which vary significantly, first by decreasing during the session, then by increasing afterward. Such an Endermologie/estrogen interaction can be compared to the clinical effects observed in some patients undergoing regular Endermologie treatment: return of menses in amenorrheal patients and a trophic effect on skin and subcutaneous connective tissue comparable to that observed during postmenopausal hormone replacement therapy.
