Analysis of kinetics of light scattering by cell suspection during aggregation: mathematical modeling of platelet disaggregation

open access: yesВісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2021
Background. Molecular mechanisms of platelet aggregation are actively studied by methods of molecular cell biology, biochemistry, applied physics, but the problem of modeling the dynamics of this process remains open.

Electrochemical study, on mercury, of a Meta-nitroarylamine derivative of nor-β-lapachone, an antitumor and trypanocidal compound

open access: yesQuímica Nova, 2010
The electrochemistry of 2,2-dimethyl-(3H)-3-(N-3'-nitrophenylamino)naphtho[1,2- b]furan-4,5-dione ([Q]-PhNO2), on mercury was investigated. The first peak is consistent with a quasi-reversible one-electron reduction of the ortho-quinone, forming [Q ...

Measurement of 33P-PO4 Absorption Kinetic Constants in Arabidopsis

open access: yesBio-Protocol, 2016
Based on the Michaelis-Menten kinetics model (Hofstee, 1952), this method allows calculation of the kinetic parameters (Vmax, Km) of phosphate uptake by Arabidopsis roots.

The Antioxidant Capability of Higenamine: Insights from Theory

open access: yesAntioxidants, 2020
Density functional theory was employed to highlight the antioxidant working mechanism of higenamine in aqueous and lipid-like environments. Different reaction mechanisms were considered for the reaction of higenamine with the •OOH radical.

Kinetic Concepts for Measuring Microbial Rate Constants: Effects of Nutrients on Rate Constants [PDF]

open access: yesApplied and Environmental Microbiology, 1986
We investigated the effect of preincubation of environmental waters amended with inorganic nutrients (nitrogen, phosphorus, and traces of iron and magnesium) on the kinetics of the microbial transformation of phenol, propanil, propyl ester of (2,4-dichlorophenoxy)acetic acid, methyl parathion, Ronnel, and methoxychlor in pond and river waters.
