The Alvord Basin in southeast Oregon contains a variety of hydrothermal features which have never been microbiologically characterized. A sampling of Murky Pot (61 degrees C; pH 7.1) led to the isolation of a novel arsenic-metabolizing organism (YeAs) which produces an arsenic sulfide mineral known
Planctomycetes are widely distributed in marine environments, where they supposedly play a role in carbon recycling. To deepen our understanding about the ecology of this sparsely studied phylum six planctomycete fosmids from two marine upwelling systems were investigated and compared with all
We have studied the adaptive response after chronic low dose irradiation (2.5 mGy/h) in wild type Drosophila melanogaster strains (Canton-S and Oregon-R), as well as mutant strains on DNA damage sensing (mei-41), DNA repair (mus209, mus210, mus309, rad54) and free radicals detoxification (sod). The
Survival rates of two Drosophila melanogaster strains, the Oregon R Wild Type (WT), and a mutant that was Low Xanthine Dehydrogenase (LXD), grown for six generations in control and in adenine-supplemented media, were determined. Although adenine was toxic to both strains, it was less toxic to the
Organelles of ectomycorrhizal fungi are known to respond to changes in the extracellular environment. The response of vacuoles, mitochondria and microtubules to short-term nickel (Ni2+) exposure were investigated in hyphal tip cells of a Paxillus involutus from a heavy metal-rich soil. Vacuoles,
It is difficult for an alcoholic individual to maintain sobriety without a place to live. Alcohol-free living centers provide a low-rent, alcohol-free environment for homeless people recovering from alcoholism. In this article, the authors describe such a living center in Portland, Oregon and its
Organisms are remarkably adapted to diverse environments by specialized metabolisms, morphology, or behaviors. To address the molecular mechanisms underlying environmental adaptation, we have utilized a Drosophila melanogaster line, termed "Dark-fly", which has been maintained in constant dark
The cardiac ryanodine receptor (RyR2) is an intracellular ion channel that regulates Ca2+ release from the sarcoplasmic reticulum (SR) during excitation-contraction coupling in the heart. The glutathione transferases (GSTs) are a family of phase II detoxification enzymes with additional functions
