An approach to the generation of polyketides was investigated,
which involved ozonolysis of 6, 7 cyclopenteno -1> 4, 5, 8 -tetrahydromethoxy-
3-methylnaphthalene (26), to produce what is believed to be
polyketide 27. Compound 26 was formed by the following sequence:
Die ls -Alder addition of 1, 2 -dim.ethylenecyclopentane and 2...
Pretreatment of male C57BL/6 mice with low doses of the persistent organochlorine
(OC) pesticide, chlordecone (CD), stimulated biliary excretion of exogenous CH up to 3-fold. Increased biliary excretion occurred without changes in hepatic ATP-binding
cassette transporter G8 (ABCG8) of the bile canaliculus or scavenger receptor class B
type I (SR-BI)...
The localized impact of blooms of the mixotrophic ciliate Myrionecta rubra in the Columbia River estuary during 2007-2010 was evaluated with biogeochemical, light microscopy, physiological, and molecular data. M. rubra affected surrounding estuarine nutrient cycles, as indicated by high and low concentrations of organic nutrients and inorganic nitrogen, respectively, associated...
For several decades, annually recurring blooms of the photosynthetic ciliate Myrionecta rubra have been observed in the Columbia River estuary in late summer. In an effort to understand the dynamics of these blooms, we investigated the genetic variability of M. rubra and its cryptophyte plastids within 3 large estuarine blooms...
In optically shallow waters, i.e., when the bottom is visible through the water,
a tantalizing variety and level of detail about bottom characteristics are
apparent in aerial imagery (Figure 1a). Some information is relatively easy to
extract from true color, 3-band imagery (e.g., the presence and extent of submerged
vegetation),...
