First Report of Bronchial Oestriasis in a Domestic Dog. [PDF]
Vet Med SciOestrus ovis bronchial myasis is described in a dog for the first time. Bronchoscopy proved essential for larval visualization and removal. Isoxazoline compounds should be considered both as a treatment and as a preventive option. ABSTRACT This study reports the first case of bronchial myiasis in a dog caused by Oestrus ovis, a parasite known to infest

Copper(II)-Photocatalyzed Radical Anellation of Nitroalkanes with Alkenes or Alkynes for the Synthesis of Isoxazolines and Isoxazoles. [PDF]
Angew Chem Int Ed EnglWe present a Cu(II)‐photocatalyzed method that employs commercially available nitroalkanes for the synthesis of isoxazolines and isoxazoles from alkenes and alkynes, respectively. Detailed mechanistic investigations revealed that the broad substrate scope, encompassing both activated and unactivated alkenes and alkynes, is attributable to a radical ...
