(19) Based on the amino acid composition of globin, amino acid analysis and N-terminal sequencing of peptides as well as a comparative analysis of the primary structure of beaver, coypu rat and otter myoglobins with the use of the fingerprinting technique, the amino acid sequence of the major component of ondatra myoglobin including 153 amino acid residues was reconstructed.
(20) The following order of animal sera was defined in comparison to human sera: cattle, pigeon, duck, sheep, cat, turkey, swine, coypu, hen, dog.
Incisor
Definition:
(a.) Adapted for cutting; of or pertaining to the incisors; incisive; as, the incisor nerve; an incisor foramen; an incisor tooth.
(n.) One of the teeth in front of the canines in either jaw; an incisive tooth. See Tooth.
Example Sentences:
(1) This suggests that molars do not maintain a fixed relationship to incisors over time, and extreme care must be taken to standardize an experiment to a specific body weight when using this method.
(2) After loss of permanent central incisors the treatment of choice could be either orthodontic closure or maintenance of the gap for a replacement-prosthetic, autotransplantation or implant.
(3) The roots of the incisor teeth should, if possible, be placed accurately in this zone and a method of achieving this is suggested.

(5) Maxillary and mandibular incisors and premolars of three rhesus monkeys were used.
(6) A case history is presented of a 10-year-old patient, who accidentally injured her maxillary central incisor.
(7) The results suggest that there is a general tendency for tooth mortality to be lower in the present survey and this change is particularly noticeable for maxillary incisor and canine teeth.
(8) Erosion was observed on all teeth, but was commonest on the upper incisors, canines and premolars, and severest on palatal surfaces.
