Acetylenic bonds are present in more than 600 naturally occurring compounds. Plant enzymes that catalyze the formation of the Delta12 acetylenic bond in 9-octadecen-12-ynoic acid and the Delta12 epoxy group in 12,13-epoxy-9-octadecenoic acid were characterized, and two genes, similar in sequence, were cloned. When these complementary DNAs were expressed in(More)
Abdo et al. Abdo et al. ABSTRACT We report on the γ-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average Large Area Telescope (LAT) γ-ray spectrum of Mrk 501 can be well described by a single power-law function with a photon index of 1.78 ± 0.03. While we observe relatively mild flux variations with the(More)
A 54-year-old woman sustained an open fracture of the right femoral shaft after a bicycle accident in 1985. Several operations were performed, the last including internal fixation using a plate and screws. In 2002, acute diverticulitis was treated with cipro-floxacin/metronidazole. In 2007, she presented with pain and swelling of the right thigh. Plain(More)
Both neutral and adaptive evolutionary processes can cause population divergence, but their relative contributions remain unclear. We investigated the roles of these processes in population divergence in house sparrows (Passer domesticus) from Romania and Bulgaria, regions characterized by high landscape heterogeneity compared to Western Europe. We asked(More)
