Bacteriological Evaluations of Swine Exposed to Lethal Levels of Gamma Radiation
Journal of Animal Science, 1973Bacteriological studies were conducted on swine exposed to a total air dose of 700 R at a rate of 1 R or 45 R/min of gamma radiation. Blood, muscle, liver, and mesenteric lymph nodes were cultured 10 days postirradiation and muscle again 5 days postslaughter during which time the carcasses had hung in a cooler.

Lethal levels of hypoxia for gulf coast estuarine animals
Marine Biology, 2007There is increasing concern about eutrophication and subsequent hypoxia problems in estuaries. The US Environmental Protection Agency has developed Water Quality Criteria (WQC) for dissolved oxygen (DO) in saltwater for Cape Cod, MA to Cape Hatteras, NC but inadequate data exists for development of such criteria for other coastal geographic areas.

Zinc nutritional status and response to lethal level of ozone exposure in rats
Bulletin of Environmental Contamination and Toxicology, 1979A number of attempts have been made to discover the chemicals which may provide protection against the lethal effects of the air pollutant ozone. The stabilizing effect of zinc on biomembranes in general is reported. It was shown in vivo and in vitro studies that lipid peroxidation in rat liver stimulated by CC1/sub 4/ was substantially decreased by ...

Victims of lethal hypothermia have decreased levels of thrombomodulin in myocardium and urine
International Journal of Legal Medicine, 2014Severe cold stress has been shown to cause changes in the expression and secretion of thrombomodulin (TM), an endothelial protein regulating haemostasis and inflammation. To further evaluate TM as a cold stress indicator, relative TM mRNA and TM protein levels in the myocardium and the concentrations of TM in serum and urine were analysed in different ...

Elevated sulfatide levels in neurons cause lethal audiogenic seizures in mice
Journal of Neurochemistry, 2009J. Neurochem. (2010) 112, 282–295.AbstractGalactosylceramide (GalCer) and 3‐O‐sulfo‐GalCer (sulfatide) are abundant sphingolipids in myelinating glial cells. However, low levels of GalCer and sulfatide have also been found in neurons, though their physiological role in these cells is unknown.

Modification of the response of rats to lethal levels of ozone by enzyme-inducing agents
Toxicology and Applied Pharmacology, 1974Abstract Rats injected daily with 30 mg/kg p -aminobenzoic acid (PABA) and exposed on day 4 to 8 ppm of the oxidant air pollutant ozone have a mean survival of 395 min, while the mean survival of uninjected control rats is 210 min and that of rats receiving a single injection of 30 mg/kg PABA just prior to ozone exposure is 212 min.

Lethal levels of pH for brook trout, Salvelinus fontinalis (Mitchill)
Canadian Journal of Zoology, 1975Fingerling brook trout, Salvelinus fontinalis (Mitchill), were subjected to acute and chronic pH stress for maximum periods of 10 000 min in a series of dilutions of sulfuric acid or sodium hydroxide at 10 and 20C after acclimation at 15C and pH 6.8. Lethal limits of pH were estimated to be pH 3.5 and 9.8 at both temperatures. There were no observable

Lethal level overexpression of γ‐tubulin in fission yeast causes mitotic arrest
Cell Motility and the Cytoskeleton, 1999gamma-Tubulin is a member of the tubulin superfamily and plays essential roles in microtubule nucleation. While the level of other tubulins, alpha- and beta-tubulin, is strictly regulated in higher eukaryotes and overexpression of beta-tubulin is toxic in yeasts, gamma-tubulin can be overexpressed by fivefold in fission yeast without any obvious defect

JUVENILE AMPHIBIANS DO NOT AVOID POTENTIALLY LETHAL LEVELS OF UREA ON SOIL SUBSTRATE
Environmental Toxicology and Chemistry, 2001Abstract We examined the effects of a forest fertilizer (urea) on newly metamorphosed terrestrial amphibians (Western toads, Bufo boreas; Cascades frogs, Rana cascadae; long-toed salamanders, Ambystoma macrodactylum; and roughskin newts, Taricha granulosa).
