| chemical characterization of milk oligosaccharides of the polar bear, ursus maritimus. | two trisaccharides, three tetrasaccharides, two pentasaccharides, one hexasaccharide, one heptasaccharide, one octasaccharide and one decasaccharide were isolated from polar bear milk samples by chloroform/methanol extraction, gel filtration, ion exchange chromatography and preparative thin-layer chromatography. the oligosaccharides were characterized by 1h-nmr as follows: the saccharides from one animal: gal(alpha1-3)gal(beta1-4)glc (alpha3'-galactosyllactose), fuc(alpha1-2)gal(beta1-4)glc (2'- ... | 2000 | 10913842 |
| molecular identification of taenia spp. in wolves (canis lupus), brown bears (ursus arctos) and cervids from north europe and alaska. | taenia tapeworms of finnish and swedish wolves (canis lupus) and finnish brown bears (ursus arctos), and muscle cysticerci of svalbard reindeer (rangifer tarandus platyrhynchus), alaskan grant's caribou (rangifer tarandus granti) and alaskan moose (alces americanus) were identified on the basis of the nucleotide sequence of a 396bp region of the mitochondrial cytochrome c oxidase subunit 1 gene. two species were found from wolves: taenia hydatigena and taenia krabbei. the cysticerci of reindeer, ... | 2011 | 21571090 |
