Dependence on age of methamphetamine-produced changes in thermoregulation and metabolism.

In contrast to juvenile mice, old mice treated with methamphetamine are unable to adequately mobilize their carbohydrate reserves. They cannot increase their overall metabolism and become hypothermic, while juvenile mice react with increased calorigenesis and hyperthermia.     

Estrogen action in the male.

Estrogen administration induces a migration of eosinophil leukocytes to ductus deferens.     

Ethanol as a ‘food’ forDrosophila melanogaster: Influence of theEbony gene

Summary The survival time of adultDrosophila melanogaster flies without food is greater in the presence of ethanol, especially for flies of strains or lines with a higher alcohol dehydrogenase activity. It seems that theebony gene can act in some populations as a selective factor favoring the ADH^F allele, as well as the minor genes enhancing the alcohol dehydrogenase activity level.Chargé de Recherches au F.
