Livestock legacy.
Recent pharmacokinetic studies (Zhou, 1989; Jori, 1990a) point out that hydrophobic photosensitising dyes with a porphyrin type macrocyclic skeleton exhibit excellent tumour-localising properties both in vitro and in vivo. Such dyes, systemically injected to experimental animals, become largely associated with serum lipoproteins (Kessel, 1990); one lipoprotein class, namely low-density lipoprot...

The human-made nature and extensive spread of a few domesticated animal species for global food production is a feature of agricultural diversity that complicates the simple, negative view of invasive species. The different impacts of livestock species on natura...

Chemists and physiologists concluded therefrom that protein, fats, carbohydrates, and certain mineral elements were the only nutrients animals required. Data from experiments made it clear, however, that the quality of the ration and its ability to promote growth could not be pre...

متن کاملChargaff's legacy.
Of Chargaff's four rules on DNA base composition, only his first parity rule was incorporated into mainstream biology as the DNA double helix. Now, the cluster rule, the second parity rule, and the GC rule, reveal the multiple levels of information in our genomes and potential conflicts between them. In these terms we can understand how double-stranded RNA became an intracellular alarm signal, ...
