| occurrence of a novel acetylated amino acid, n(alpha)-acetylhistidine, in skeletal muscle of freshwater fish and other ectothermic vertebrates. | the occurrence of n(alpha)-acetylhistidine (nah) in skeletal muscle of 91 species of freshwater fish and 9 species of other ectothermic vertebrates was investigated, with consideration of phylogenetic relationships. of the 91 freshwater fish species examined, 13 species (7 cichlids, 5 anabantids, and 1 catfish) contained considerable amounts (>1 micromol/g) of nah in their skeletal muscles. the highest level (10.37 micromol/g) of nah was found in the tissue of betta splendens (siamese fighting f ... | 2009 | 19100335 |
| molecular identification of the advanced third-stage larvae (adv l(3)) of gnathostoma lamothei in tabasco, mexico. | advanced third-stage larvae (adv l(3)) of gnathostoma spp. were collected from the muscle tissue of three species of freshwater fish (i.e., gobiomorus dormitor, petenia splendida, and parachromis managuensis) in swamps of centla, tabasco, mexico. nine sequences of the its2 of the ribosomal dna of gnathostoma spp. were compared with sequences obtained from genbank for g. binucleatum, g. lamothei, g. miyazakii, g. spinigerum, and g. turgidum. sequences of the adv l(3) from p. splendida (isla china ... | 2010 | 19874909 |
