A gene cluster responsible for the biosynthesis of the antitumor agent
cetoniacytone A was identified in Actinomyces sp. strain Lu 9419, an
endosymbiotic bacteria isolated from the intestines of the rose chafer beetle. The
nucleotide sequence analysis of the 26 Kb DNA region revealed the presence of 17
complete ORFs,...
The critical contribution of this dissertation is to provide a better
understanding of the fundamental Chemical Bath Deposition (CBD) growth
kinetic and mechanism for the well known II-VI semiconductor CdS using the
newly developed continuous flow microreactor. This continuous flow microreactor
provides the temporal resolution to control the homogeneous reaction...
The potential for nanomedicine to reduce toxicity and improve therapeutic response to radiation is vast. Clinically, this potential has thus far only begun to be realized with the recent success of the radioenhancing nanoparticle, NBTXR3 by Nanobiotix. Radioenhancing nanoparticles, however, represent only a small class of nanomaterials that may be...
The seasonal distribution of bioavailable organochiorine contaminants in surface
water and the potential environmental factors influencing their bioavailability were
evaluated. The study was carried at the lower Willamette River at Portland Harbor, Oregon
where surface water runoff varied according to season. Bioavailable water concentrations of
DDTs and PCBs were determined...
Fusion reactions with radioactive neutron-rich projectiles have been the subject of much recent theoretical and experimental interest. Predictions of enhancement of the cross section due to the use of a neutron-rich projectile may have implications for synthesis of heavy nuclei. In this work, the fusion-fission excitation functions were measured for...
Replication of plasmid molecules containing either a left-end or a
right-end adenovirus origin was investigated. When the plasmids were
linearized to expose their respective adenovirus termini, mixed, and
transfected with helper adenovirus DNA into the human 293 cell line, a
new molecule was detected. The new molecule was the size...
This proposal by the Coniferous Biome investigators requests support for the second year of a highly integrated series of investigations within the Analysis of Ecosystem program of the United States effort under the International Biological Program. The program for the Coniferous Forest Biome has been approved by the U.S. Executive...
