Teratogenicity of polybrominated biphenyls in rats
(Elsevier, 1977-08)
The teratogenic potential of a mixture of polybrominated biphenyls (PBB) was investigated. Pregnant Wistar albino rats were given single doses of PBB in seasame oil by gavage on one day of pregnancy, from day 6 through 14 ...
Toxicity of polybrominated biphenyls (Firemaster BP-6) in rodents
(Elsevier, 1975-12)
Pregnant rodents were fed concentrations of a mixture of polybrominated biphenyls (Firemaster BP-6) during the pregnancy. The material appears to be weakly teratogenic, causing exencephaly and cleft palate in mice. Decreasing ...
A cellular model for studying accommodation to environmental stressors: Protection and potentiation by cadmium and other metals
(Elsevier, 1978)
Exposure of P. polycephalum to a subthreshold challenge of Cd2+, which did not delay mitosis, elicited a protective response against a mitotic delay resulting from subsequent exposure to a suprathreshold challenge of Cd2+. ...
A cellular model for studying accommodation to environmental stressors: A protective response to subtoxic exposure to cadmium
(Elsevier, 1978)
A model is described for testing the effect of exposure to subtoxic challenge upon cellular integrity. The model incorporates Physarum polycephalum as a biological assay system, the ability of the cell to traverse the cell ...
The effect of parathyroid hormone on the renal accumulation of lead
(Elsevier, 1978-02)
The effect of parathyroid hormone (PTH) on renal accumulation of lead has been assessed in two experiments on mature rats. In the first experiment, lead was given per os, followed by subcutaneous injections of PTH (100 ...
Patterns of urban heat-wave deaths and implications for prevention: Data from New York and St. Louis during July, 1966
(Elsevier, 1972-03)
Patterns of urban heat wave deaths in New York and St. Louis during July 1966 indicate not only the impact of environmental stress on heat-susceptible segments of the population but provide clues to the possible prevention ...
