Adsorption of molybdate and tetrathiomolybdate onto pyrite and goethite: effect of pH and competitive anions.
The adsorption of two major molybdenum (Mo) species, molybdate (MoO4(2-)) and tetrathiomolybdate (MoS4(2-)) onto two main iron minerals pyrite (FeS2) and goethite (FeOOH) is addressed to elucidate… Expand

p53 exerts its tumor suppressor activity through both transcription‐dependent and transcription‐independent processes. Although the transcription‐dependent activity of p53 has been extensively… Expand
DrRRA: a novel response regulator essential for the extreme radioresistance of Deinococcus radiodurans
Two‐component systems are predominant signal transduction pathways in prokaryotes, and also exist in many archaea as well as some eukaryotes. A typical TCS consists of a histidine kinase and a… Expand

A novel fluorescent substrate was devised for the sirtuin (SIRT) class of human protein deacetylases comprised of a peptide sequence containing a single acetyl-lysine residue, with a fluorescent… Expand
Influence of pH, ionic strength and humic acid on competitive adsorption of Pb(II), Cd(II) and Cr(III) onto titanate nanotubes
Abstract Titanate nanotubes prepared by alkaline hydrothermal method were characterized by N 2 adsorption/desorption, X-ray diffraction, high resolution transmission electron microscopy and Fourier… Expand
The role of photodynamic therapy in overcoming cancer drug resistance.
Many modalities of cancer therapy induce mechanisms of treatment resistance and escape pathways during chronic treatments, including photodynamic therapy (PDT). It is conceivable that resistance… Expand
Modeling the competitive effect of phosphate, sulfate, silicate, and tungstate anions on the adsorption of molybdate onto goethite.
The mobility of Mo in soils and sediments depends on several factors including soil mineralogy and the presence of other oxyanions that compete with Mo for the adsorbent's retention sites. Batch… Expand
A Review of Molybdenum Adsorption in Soils/Bed Sediments: Speciation, Mechanism, and Model Applications
Mo is an essential trace element for both plants and animals in low concentrations (<5 ppm). However, provoked by uncontrolled industrial waste releases in freshwater or seawater, it is plausible… Expand
Characterization of hematite dissolution affected by oxalate coating, kinetics and pH
Abstract Iron-complexes on the surface of minerals may play an important role in Fe dissolution in acidic cloud water containing certain organic ligands, and dissolved Fe serves as a critical… Expand
Extremely high magnetoresistance and conductivity in the type-II Weyl semimetals WP2 and MoP2
The peculiar band structure of semimetals exhibiting Dirac and Weyl crossings can lead to spectacular electronic properties such as large mobilities accompanied by extremely high magnetoresistance.… Expand
