Use of transgenic animals for carcinogenicity testing: considerations and implications for risk assessment
Autor: D, Gulezian, D, Jacobson-Kram, C B, McCullough, H, Olson, L, Recio, D, Robinson, R, Storer, R, Tennant, J M, Ward, D A, Neumann
Publikováno v: Toxicologic pathology. 28(3)
Advances in genetic engineering have created opportunities for improved understanding of the molecular basis of carcinogenesis. Through selective introduction, activation, and inactivation of specific genes, investigators can produce mice of unique g

Co-Ordinating Systems and Behaviour in Hydra
Autor: C. B. McCULLOUGH, L. M. Passano
Publikováno v: Journal of Experimental Biology. 41:643-664
1. Two further co-ordinating systems, the rhythmic potential (or RP) and the pre-locomotor burst (PLB) systems, are described from several species of Hydra . 2. RP impulses may be recorded from anywhere in the column. They are small, distinctive in s

Toxicologic and carcinogenic evaluation of Fenvalerate in the B6C3F1 mouse
Autor: C M, Parker, C B, McCullough, J B, Gellatly, C D, Johnston
Publikováno v: Fundamental and applied toxicology : official journal of the Society of Toxicology. 3(2)
Groups of 50 male and 50 female B6C3F1 mice were fed dietary concentrations of 10, 50, 250 or 1250 ppm Fenvalerate for 2 years. Two groups of control mice, 50 per sex per group, received basal diet only. Mortality was increased and body weight was si

PACEMAKER INTERACTION IN HYDRA
Autor: C. B. Mccullough
Publikováno v: American zoologist. 5
Previous reports have described in detail the characteristics of two pacemaker systems in hydras. Each of these, the rhythmic potential (RP) system located near the base of the polyp, and the contraction burst (CB) system at the sub-hypostome, has it
