Acridine orange (AO), ethidium bromide (EB), ethyl methanesulfonate (EMS) and 8- ethoxycaffeine ( EOC ) were fed to larvae of Drosophila melanogaster in order to test their capacity for the induction of meiotic recombination in males. Our results show that AO and EB increase significantly the male recombination frequencies. No relationship between(More)
OBJECTIVE To evaluate the relationship of fetal erythropoiesis to both maternal and fetal serum alpha-fetoprotein (AFP) levels. STUDY DESIGN We evaluated the relationships between maternal serum AFP levels and fetal hemoglobin, hematocrit, red blood cell count, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin(More)
Larvae and adults ofD. melanogaster andD. simulans were fed with acridine orange, in order to test sensitivity differences between the species. Our results show that, of the two species,D. simulans is more resistant in the larval stages, andD. melanogaster is more resistant in the adult stage. Furthermore, adult males of both species are more sensitive than(More)

Antiphospholipid syndrome (APS) affects young patients in the most productive years of their life, and the consequences of organic or tissue damage involve a decrease in health-related quality of life (HRQoL). While acute disease manifestations of APS are well known, information on the long-term prognosis and damage in affected patients is still very(More)
