Validation of a two-parameter quantitative structure–activity relationship as a legitimate tool for rational re-design of horseradish peroxidase
(Wiley Subscription Services, Inc., A Wiley Company, 2007-09-01)
Previously reported rates of reaction between six mutant strains of the enzyme horseradish peroxidase (HRP) and a test substrate, 2-methoyxpyhenol, were found to correlate with characteristic binding distances computed ...
Synthesis and characterization of molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1992-06-30)
Details concerning the relationships between the structural, chemical and catalytic properties of Mo nitrides have been elucidated. A series of Mo nitride catalysts were prepared by the temperature programmed reaction of ...
The structure and function of supported molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1994-03)
A series of [gamma]-Al2O3 supported Mo nitrides were prepared by the temperature programmed reaction of supported molybdates with NH3. Several loadings, heating rates, and space velocities were employed in an attempt to ...
Fermentation monitoring by polymeric-resin-based microbiol assay
(Wiley Subscription Services, Inc., A Wiley Company, 1983-03)
A polymeric-resin-based microbiological assay is shown to yield results consistent with classical inhibition zone theory. This novel assay is applicable to cycloheximide, an antifungal antibiotic, at concentrations below ...
Pt/MCM-41 catalyst for selective catalytic reduction of nitric oxide with hydrocarbons in the presence of excess oxygen
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic Publishers ; Springer Science+Business Media, 1998-03)
First results are reported on the use of MCM-41 mesoporous molecular sieve as the support for Pt for the selective catalytic reduction of NO by hydrocarbons in the presence of O 2 . MCM-41 provided the highest specific NO ...
Cell immobilization in k -carrageenan with tricalcium phosphate
(Wiley Subscription Services, Inc., A Wiley Company, 1982-08)
The objectives of this research were to investigate the growth of immobilized yeast cells in k -carrageenan gel and study the effect of trapping hydroxyapatite (tricalcium phosphate) crystals into the matrix. Using k ...
Countercurrent gradient chromatography: A continuous focusing technique
(Wiley Subscription Services, Inc., A Wiley Company, 1995-12-05)
The continuous separation of proteins was performed in a countercurrent gradient chromatography (CGC) system. A magnetically stabilized fluidized bed (MSFB) was used to establish true countercurrent contact of a solid resin ...
Chemical extraction of indigo from Indigofera tinctoria while attaining biological integrity
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-08)
Indigofera tinctoria was permeabilized with 20% methanol (v/v) at 25 °C and released 8±2 μg indigo g −1 dry plant material (excluding roots). This is equivalent to 42±11% of the total indican within the cells. The plants ...
A model of the renal cortex and medulla
(Elsevier, 1967)
Mathematical models of the renal cortex and medulla are developed. The glomerular filtration rate is treated as an input parameter. The differential equations for transfer of water and solutes are developed under the ...
Externally Applied Cyclic Strain Regulates Localization of Focal Contact Components in Cultured Smooth Muscle Cells
(Kluwer Academic Publishers-Plenum Publishers; Biomedical Engineering Society ; Springer Science+Business Media, 2002-07)
Mechanical signals are critical regulators of cellular gene expression, yet little is understood of the mechanism whereby cells sense mechanical forces. In this study we have tested the hypothesis that mechanical strain ...
