[The posthumous birth of Évariste Galois (1811-1832)].

The publication of Galois' works in the Journal de Liouville (1846) was announced during a debate between academicians Libri and Liouville as early as 1843. Rather than limiting this publication to a study of controversy, we would like to show that it is inscribed in a larger context of the redefinition of algebra, which this debate illuminates. In order to understand the rediscovery of Galois, it must be inscribed in the median time of mathematical practices and usages.

The effects of 20-hydroxyecdysone and 17β-estradiol on the skin of ovariectomized rats.

Objective: 20-hydroxyecdysone has numerous favorable effects on a variety of organs, including the skin, where it improves wound healing. It is devoid of estrogenic and androgenic effects. Therefore, application of 20-hydroxyecdysone might be a new approach to improve skin conditions in postmenopausal women, and this was investigated in ovariectomized (OVX) rats.

Metabolic effects of 20-OH-ecdysone in ovariectomized rats.

Postmenopausal women develop often obesity which may be prevented by 20-OH-Ecdysone (Ecd). This was investigated in ovariectomized (ovx) rats. They were orally treated with 3 doses of Ecd (18, 56 or 116 mg/day/animal).
