pH Dependence of Iron Speciation in Saccharomyces cerevisiae Vacuoles
Vacuoles in yeast are vital organelles that take on many important biological roles. They are responsible for collecting and detoxifying iron such that reactive oxygen species are not formed. They are also important storage ...
MICROMAGNETIC STUDIES OF THE TRANSITION BETWEEN VORTEX AND SINGLE-DOMAIN STATES IN SUB-100 NM NANODOTS
(2012-04-26)
Understanding energy barriers involved in nucleating and annihilating magnetic vortices in nanodots is important for magnetic memories and nano-oscillators. We used a “rigid-vortex approximation'' and micromagnetic approach ...
Genetic and Functional Analysis of Siderophores in Trichoderma virens
(2008-05-21)
Trichoderma virens, an avirulent plant symbiotic fungus ubiquitous in soils
worldwide, is remarkable as it induces systemic resistance in plants, enhances plant
growth, and acts as a mycoparasite of plant-pathogenic ...
Mechanisms of Manganese Transport Across Cell Membranes
(1994)
The uptake of manganese (Mn) by human fibroblast cells was studied to determine the chemical form of Mn used by the cells. These experiments tested the uptake of free Mn and Mn bound to the plasma protein, transferrin. Mn ...
Trace Elements In Mental Retardation
(1979)
Overt poisoning by some trace elements (Cu, Hg, Mn, Pb) is known to cause extensive central nervous system damage which can result in mental retardation. Recent evidence indicates that low, undetectable exposure to lead ...
