Development of cytochromes P450 in avian species as a biomarker for environmental contaminant exposure and effect: Procedures and baseline values Development of cytochromes P450 in avian species as a biomarker for environmental contaminant exposure and effect: Procedures and baseline values
As in mammals and fish, birds respond to many environmental contaminants with induction of hepatic cytochromes P450. In order to monitor cytchromes P450 in specific avian species, for assessing the status of that species or the habitat it utilizes, it is necessary to have background information on the appropriate assay conditions and the responsiveness of cytochrome P450 induction in...

Borehole geophysical logging for water-resources investigations in Pennsylvania Borehole geophysical logging for water-resources investigations in Pennsylvania
Borehole geophysical logging is a procedure to collect and transmit specific information about the geologic formations penetrated by a well by raising and lowering a set of probes or sondes that contain water-tight instruments in the well. The data collected can be used to determine general formation geology, fracture distribution, vertical borehole flow, and water-yielding capabilities.

Toxicity and oxidative stress of different forms of organic selenium and dietary protein in mallard ducklings Toxicity and oxidative stress of different forms of organic selenium and dietary protein in mallard ducklings
Concentrations of over 100 ppm (mg/kg) selenium (Se) have been found in aquatic plants and insects associated with irrigation drainwater and toxicity to fish and wildlife. Composition of diet for wild ducklings can vary in selenium-contaminated environments. Earlier studies have compared toxicities and oxidative stress of Se as selenite to those of seleno-DL-methionine (DL) in mallards...

New records of predaceous diving beetles (Coleoptera:Dytiscidae) in Maine New records of predaceous diving beetles (Coleoptera:Dytiscidae) in Maine
Locations, habitat descriptions, and collection dates are listed for new records of 4 genera and 12 species of predaceous diving beetles (Coleoptera: Dytiscidae) in Maine. Previously, 17 genera and 53 species of the aquatic beetle were reported from Maine.

Purification and immunochemical detection of β-naphthoflavone-and phenobarbital-induced avian cytochrome P450 enzymes Purification and immunochemical detection of β-naphthoflavone-and phenobarbital-induced avian cytochrome P450 enzymes
Livers from mallards (Anas platyrhynchos) were treated with either β-naphthoflavone (50 mg/kg) or phenobarbital (70 mg/kg). Purification of induced hepatic cytochrome P450 was accomplished using both DEAE and hydroxyapatite columns, as well as sodium dodecyl sulfate polyacrylamide gel electrophoresis separation. Polyclonal antibodies to these proteins were then produced in young male New...
