(2014-04-24)The expression of genes that control iron (Fe) uptake and distribution (i.e., Fe utilization- related genes) is under a strict regulation. Fe deficiency strongly induces Fe utilization- related gene expression; however, ...

(2021-06-01)Low-molecular-mass (LMM) transition metal complexes are thought to play essential roles in metal ion trafficking, regulation, and signaling in biological systems. Their chemical identities remain largely unknown due to ...
-
(2013-08-30)The speciation of iron in intact Jurkat cells and their isolated mitochondria was assessed using biophysical methods. [Fe4S4]^(2+) clusters, low-spin (LS) Fe^(II) heme centers, non-heme high-spin (NHHS) FeII species, ...
-
(2012-02-14)Sophisticated catalytically active sites of metalloenzymes provide inspiration to synthetic chemists, as the metal coordination environments are often atypical to those found on the chemist's benchtop. Furthermore, ...
-
(2013-04-19)Astronauts in space flight missions are exposed to increased iron (Fe) stores and galactic cosmic radiation, both of which independently induce oxidative stress. Oxidative stress can result in protein, lipid, and DNA ...
-
(2021-08-25)The therapeutic nature and mechanisms of in vitro nitric oxide (NO) release from dinitrosyl iron complexes (DNICs) are explored herein. First, the ideal primary coordination environment for the sustained liberation of NO ...
-
(2013-12-03)Fe metabolism in budding yeast Saccharomyces cerevisiae was studied using an integrative systems-level approach involving Mӧssbauer, EPR, UV-Vis spectroscopy and LC-ICP-MS, combined with conventional biochemical techniques. ...
-
(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 ...
-
(2017-12-13)Interest in applications of x-ray fluorescence (XRF) is greatly increasing, but the diversity of applications of XRF data has yet to be fully exploited. This dissertation presents three projects showcasing different ...

Little and Large Herbivores as Indicators of Trophic Transfer: Do Trace Nutrients Drive Populations? (2019-10-07)Trace minerals, such as copper, iron, and zinc, are essential for reproduction, growth, and immunity of mammalian herbivores and the growth of their populations. I examined the relationship between supplies of essential ...

(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 ...
