Effects of chlorinated aliphatic hydrocarbon degradation on the metabolic enzymes in Nitrosomonas europaea

Creator:: Fawcett, Kimberly A.
Abstract:: The toxic effects of degrading the chlorinated hydrocarbons trichloroethylene (TCE), chloroform (CF) and cis-1,2-dichloroethylene (cis-1,2-DCE) were studied in the bacterium Nitrosomonas europaea. N europaea is an ammonia-oxidizing bacterium that obtains all of its energy from the oxidation of ammonia to nitrite. This metabolic process involves two enzymes, ammonia monooxygenase (AMO)...

Alteration of cholesterol disposition by chlordecone is not explained by induction of cyp7a or cyp4a1

Creator:: Lee, JungA
Abstract:: Liver X receptor (LXR), farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR) are adopted orphan nuclear receptors that function as lipid sensors. These receptors respond to cellular lipid levels and regulate the expression of target gene. Previously, it was demonstrated that low doses of chlordecone (CD) pretreatment disturbed exogenous...

Automated manipulation of zebrafish embryos for high-throughput toxicology screening of nanomaterials

Creator:: Mandrell, David
Abstract:: The field of nanotechnology has been rapidly developing new materials. These materials have become incorporated into consumer products and the environment after only minimal assessment of their effects on human health or the environment. The toxicity of these new nanomaterials remains unknown due to the unpredictable nature of the core...

Chemical and environmental factors affecting pesticide volatilization from turfgrass

Creator:: Conway, Michael S.
Abstract:: Volatile loss rates of pesticides from turfgrass were measured using the Backward-Time Lagrangian Stochastic Dispersion model (Flesch et al., 1995). Solar radiation, ambient temperature, surface temperature, relative humidity, wind direction, and wind speed were monitored continuously. Growth regulator was applied to the turf plot several days before pesticide application to...

The influence of light, temperature and humidity on the herbicidal activity of bromoxynil (3,5-dibromo-4-hydroxybenzo-nitrile) on Amsinckia intermedia

Creator:: Zimmerman, Martin (Martin Joseph)
Abstract:: The use of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) to control broadleaf weeds in cereal crops has become widespread. This herbicide has not always performed satisfactorily for reasons which were not clearly evident. The effects of temperature, light and humidity on the herbicidal activity of bromoxynil on coast fiddleneck, Amsinckia intermedia, were studied. Fiddleneck...

Carcinogenicity and acute toxicity of dimethylnitrosamine in rainbow trout (Salmo gairdneri)

Creator:: Grieco, Mary Porter
Abstract:: A dose related carcinogenic response was established for dimethylnitrosamine administered in the diet of rainbow trout (Salmo gairdneri). An equation was derived for the relationship between dose and hepatocellular carcinoma incidence. From a published dose response study using Porton rats as a test animal, a second equation was derived for...

Nutritional influences affecting senecio toxicity in laboratory animals

Creator:: Buckmaster, Gary Wayne
Abstract:: The objective of this research project was to evaluate the toxicity of local pyrrolizidine alkaloid containing plants and to examine the influence of dietary protein, with particular reference to the amino acid cysteine, upon this toxicity. Senecio vulgaris (common groundsel) was shown to be more toxic than Senecio jacobaea (tansy...

The in vivo metabolism of ethyl-N, N,-di-n-propylthiolcarbamate in rats

Creator:: Ong, Visitacion Yu
Abstract:: The metabolism of ¹⁴C-labeled ethyl -N, N-di-n- propylthiolcarbamate (EPTC- ¹⁴C) was studied in adult female rats. Single oral doses of EPTC-¹⁴C ranging from 0. 6 to 100. 6 mg were given and the elimination pattern of ¹⁴C was determined. Results of 18 experiments showed that increasing the doses of EPTC-...

Bacterial 16S ribosomal DNA analysis of pyrrolizidine alkaloid detoxifying enrichments from the ovine rumen

Creator:: Gray, Diane R.
Abstract:: Bacterial cultures enriched from sheep rumen fluid have demonstrated the ability to detoxify pyrrolizidine alkaloids (seneciphylline and jacobine) in tansy ragwort (Senecio jacobaea). The microbes are difficult to isolate using classical anaerobic techniques, therefore, microbes from two different enrichment cultures demonstrating similar degradation activity were identified using their 16S ribosomal...
