Inorganic concepts relevant to metal binding, activity, and toxicity in a biological system
(Elsevier, 1991-12)
Selected physical and inorganic concepts and factors which might be important in assessing and/or understanding the fate and disposition of metal compounds in a biological environment are reviewed. The stereochemistry ...
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 ...
Lifetime effects of intratracheally instilled nickel subsulfide on B6C3F1 mice
(Elsevier, 1986-08)
A nickel subsulfide (Ni3S2) lung tumor model for the study of metal carcinogenesis was evaluated using intratracheally dosed B6C3F1 mice. A preliminary study of the survival of mice 14 days after a single intratracheal ...
Contamination of green bay water with lead and cadmium by a 37-m long, 2-m draft research vessel
(Elsevier, 1992-09-07)
During late April 1989, Green Bay, Lake Michigan water was sampled for dissolved concentrations of lead and cadmium. Samples used to document horizontal contamination of the water by a research vessel were collected using ...
Mechanistic steps in the photoreduction of mercury in natural waters
(Elsevier, 1994-09-01)
Elemental mercury accounts for 10-50% of the dissolved mercury in lakes but plays a vital role in the cycling of this element in lacustrine environments. The view is advanced that a large fraction of the Hg(0) is generated ...
Cutaneous effects of exposure to polybrominated biphenyls (PBBs): The Michigan PBB incident
(Elsevier, 1982-10)
In 1973 an environmental accident occurred in northern Michigan in which 1000-2000 pounds of the toxic fire retardant polybrominated biphenyl (PBB) was added to the livestock food supply of much of northern Michigan. PBB ...
Analysis of proteins expressed at the time of murine organogenesis
(Wiley Subscription Services, Inc., A Wiley Company, 1991-06)
Two-dimensional electrophoretograms were prepared from wild-type C57BL/6J embryos from day 7.5 through day 9.0 of development. This time period encompasses a critical window of development as the embryo traverses from an ...
Cultured rat embryo accumulation of DNA, RNA, and protein following maternal administration of sodium arsenate
(Elsevier, 1982-06)
Whole embryo culture techniques were used to test the effects of sodium arsenate on the rates of DNA, RNA, and protein accumulation. Rat embryos were isolated on the 10th gestational day (sperm DAY = Day 0) either 4 or 24 ...
Specific inhibition of mouse oocyte nuclear protein phosphatase-1 stimulates germinal vesicle breakdown
(Wiley Subscription Services, Inc., A Wiley Company, 2003-05)
Okadaic acid (OA)-induced germinal vesicle breakdown (GVBD) and localization of protein phosphatase-1 (PP1) in oocyte nuclei are suggestive of PP1's role in regulating oocyte GVBD. To explore this possibility, we microinjected ...
