Die neueste Sondemummer von Laboratory Animals enthalt den sechsten Report der BVAAWIFRAME/RSPCA/UFAW1 Joint Working Group on Refinement. Der fiir den Bericht zustandigen working party gehoren 12 Mitglieder an, die alle in England (UK) domiziliert sind; ihr Vorsitzender ist David Morton (Medizinische Fakultat der Universitat Birmingham), die Berichts-Redaktorin und Korrespondenz fiihrende Perso...

For a locally compact group G we look at the group algebras C 0 (G) and C * r (G), and we let f ∈ C 0 (G) act on L 2 (G) by the multiplication operator M (f). We show among other things that the following properties are equivalent: 1. G has a compact open subgroup. 2. One of the C *-algebras has a dense multiplier Hopf *-subalg-ebra (which turns out to be unique). 3. There are non-zero elements...

Chinese brake fern (Pteris vittata L.) is a hyperaccumulator of arsenic (As) that grows naturally on soils in the southern United States. It is reasonable to expect that mycorrhizal symbiosis may be involved in As uptake by this fern. This is because arbuscular mycorrhizal (AM) fungi have a well-documented role in increasing plant phosphorus (P) uptake, P and As have similar chemical properties...

We studied phagolysosomal pH in rabbit alveolar macrophages (AM) incubated with 0-15 microM chloroquine. There was a dose-related increase in pH with chloroquine concentration. Electron microscopy showed that chloroquine increased lysosomal size. In a second experiment we studied dissolution of radiolabeled cobalt oxide particles by rabbit AM, phagolysosomal pH, and lysosomal size. The cells we...

Abstract Essential oils can modulate ruminal biohydrogenation. Dorper x Santa Inês lambs (n=40; initial BW of 30.3 ± 5.76 kg and 92 9 d old) were assigned to a randomized complete block evaluate the effect different levels arnica montana essential oil (AM) as feed additive on fatty acid (FA) profile meat. The treatments were: 25 mg monensin/kg DM (M25); four monensin-free diets containing 0 (AM...
