(17) The chinchilla, like the GP, is a New World hystricomorph.
(18) This is in contrast to the previously reported sequence for CCK8 from the South American hystricomorphs, guinea pig and chinchilla, which differs in a substitution of valine for methionine in position 3 from the NH2-terminus.
(19) This suggested that New World monkeys, like the New World hystricomorph rodents such as the guinea pig and the coypu, might have insulins whose sequences differ markedly from those of Old World mammals.
(20) Insulin from a hystricomorph rodent, coypu (Myocaster coypus), was isolated and purified to near homogeneity.
Rodent
Definition:
(v. t.) Gnawing; biting; corroding; (Med.) applied to a destructive variety of cancer or ulcer.
(v. t.) Gnawing.
(v. t.) Of or pertaining to the Rodentia.
(n.) One of the Rodentia.
Example Sentences:

(2) This is the first clear example of activation of the K-ras gene by ethylating agents in a rodent lung tumor system.
(3) The relatively high incidence of nephroblastoma in the Nb rat using transplacentally administered ENU appears to represent a suitable basis for developing a rodent model of human nephroblastoma or Wilms' tumor.
(4) Male Sprague Dawley rats either trained (T, N = 9) for 11 wk on a rodent treadmill, remained sedentary, and were fed ad libitum (S, N = 8) or remained sedentary and were food restricted (pair fed, PF, N = 8) so that final body weights were similar to T. After training, T had significantly higher red gastrocnemius muscle citrate synthase activity compared with S and PF.
(5) This model of protective immunity in a Brugia-susceptible small rodent may provide a useful system for identification of molecularly defined filarial-protective immunogens.
(6) The receptor pattern observed in tumors does not support the hypothesis previously raised in the case of chemically induced colonic tumors in rodents.
(7) It is concluded that these rodent studies do not implicate any specific inhalational anesthetic agent in fetal toxicity, and that the effects of additional factors, such as stress, must be considered.
(8) In the course of routinely performed subchronic toxicity studies with laboratory rodents, functional neurotoxicity, i.e.
(9) Particularly striking is the distribution of CpG dinucleotides within human and rodent APRT genes.
(10) There was less of an increase following a blood meal infected with the rodent malaria parasite, Plasmodium berghei.
(11) An analysis of 54 protein sequences from humans and rodents (mice or rats), with the chicken as an outgroup, indicates that, from the common ancestor of primates and rodents, 35 of the proteins have evolved faster in the lineage to mouse or rat (rodent lineage) whereas only 12 proteins have evolved faster in the lineage to humans (human lineage).
(12) The differences in immunoreactivity between rodent and human amyloid plaques are consistent with other findings showing that cellular genes, not infectious purified prions, encode PrP.
