A Multi-Tiered Approach Using Daphnia magna to Assess Chlorpyrifos Risk to Aquatic Receptors

Creator:: Maggio, Stephanie A.
Abstract:: Chlorpyrifos (CPF) is a widely used broad-spectrum organophosphate insecticide. Following exposures, CPF and its more toxic oxon metabolite (CPFO) elicit neurotoxic effects by inhibiting the activity of the acetylcholinesterase enzyme (AChE), resulting in altered fitness and death at high doses. Following exposure, organisms bioactivate CPF to CPFO through the Cytochrome...

A revision of Juncus subgenus genuini (Juncaceae) in the Pacific states

Creator:: Lint, Harold LeRoy
Abstract:: A study was made of the subgenus Genuini of the genus Juncus in the Pacific States, California, Oregon and Washington. Extensive morphological comparisons, geographical distributions, habitat differences and observations of apparent presence or absence of natural hybrids provided the major data sources. Cytological studies were made, but were inconclusive. Eleven...

A phytochemical study of Achlys triphylla (Smith) DC., (Berberidaceae)

Creator:: Born, Alvin Edmund
Abstract:: Achlys triphylla, a member of a medicinally active family containing alkaloids, was examined phytochemically to determine its possible value as a source of medicinal agents. Pharmacological testing of the crude ethanol extract exhibited a competitive inhibition of acetylcholine and histamine. Purification of alkaloid 'A' from the crude ethanol extract and...
