Antiviral and immune-based intervention strategies have been evaluated in vivo in animal models based on infections with lentiviruses and other retroviruses to explore their effect on preventing or limiting de novo virus infection. Variables that can be experimentally manipulated to address specific questions relevant to postexposure prophylaxis (PEP ...

Journal of Experimental Biology, 1948
ABSTRACT In the first paper of this series (Steven, 1948) it was shown that the tissues of the trout (Salmo trutta Linn.) normally contain β-carotene, lutein and astacene. Lutein and astacene occur as esters in the red and yellow chromatophores of the skin, and may also be present in the muscles as free hydroxy-carotenoids.

Cytogenetic Studies in Animals
1982It is clearly impossible to provide a detailed discussion of all the possible areas of research encompassed by the title of this presentation. The intention is to provide some indication of the types of cytogenetic assays that can be performed in order to indicate the clastogenic potential of an agent, whether the data obtained can reasonably be used ...
