Determination of the kinetic parameters of phosphofructokinase dissociation [PDF]

open access: yesFEBS Letters, 1975
It has been demonstrated that phosphofructokinase from rabbit skeletal muscle is dissociated into inactive subunits in the presence of low enzyme concentrations ]I] I Dissociation constants of about 10e6 M, as estimated from computer simulations [2-S], suggested physiological significance of the dissociation process in the regulation of cellular ...

Parameter balancing: consistent parameter sets for kinetic metabolic models [PDF]

open access: yesBioinformatics, 2019
Abstract Summary Measured kinetic constants are key input data for metabolic models, but they are often uncertain, inconsistent and incomplete. Parameter balancing translates such data into complete and consistent parameter sets while accounting for predefined ranges and physical constraints. Based on

Measurement of Cell Kinetic Parameters in Meningiomas

open access: yesNeurologia medico-chirurgica, 1997
Cell kinetic parameters were measured in four cases of meningioma showing regrowth. The cell cycle time (Tc) and tumor doubling time (Td) were established by histological evaluation of the biopsy specimens and calculation of the growth curve based on computed tomography (CT)/magnetic resonance (MR) images.
