Ion-Exchange Selectivity of Anion Exchange Resin Modified with Polystyrenesulfonic Acid
Analytical Sciences, 2004 In order to change the ion-exchange selectivity of anion-exchange resin, the surface of a gel-type anion exchange resin was modified with anionic polyelectrolyte, polystyrenesulfonic acid. Using this modified resin, the ion-exchange rate of nitrate was little decreased, but that of sulfate was evidently decreased. It is considered that the ion-exchange

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Selected properties of cobalt-contaminated soil following the application of neutralising substances
Environmental Protection and Natural Resources, 2016 The aim of the study was to determine the influence of increasing cobalt soil contamination (0 mg·kg−1, 20 mg·kg−1, 40 mg·kg−1, 80 mg·kg−1, 160 mg·kg−1, 320 mg·kg−1) after the application of neutralising substances on selected soil properties.

Amino acid neurotransmitters in the CNS
FEBS Letters, 1986 D‐Aspartate exchange, defined as amino acid‐stimulated D‐[3H]aspartate efflux, was investigated in a preparation of rat brain synaptosomes. The efflux of radiolabelled D‐aspartate was found to be enhanced by micromolar concentrations of externally added D‐ and L‐aspartate, L‐glutamate, L‐cysteate.and L‐cysteinesulphinate.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Growth and nutrient concentrations of alfalfa and common bean as influenced by soil acidity. [PDF]
, 1989 Growth and nutrient utilization of alfalfa (Medicago sativa L. cv. Arc) and common bean (Phaseolus vulgaris L. cv. Carioca) were studied in an acid soil adjusted to eight levels of soil acidity by lime addition.
