Monod equation

Despite this limitation the present work shows a revision of the procedure described before by Chhabra et al. Table 2 Values of Q c ,max obtained fitting the curves showed in Figs.

Our calculations give different values for the maximum oxygen consumption rate Q c ,maxwhen different oxygen pressure values high and low p O 2 are considered at the interface cornea-tears film.

Considering the limitations of the model to explain the rate of change of the experimental data, which does not ve to the tendency of the value reported by Bonanno et al. Considering this, we proceeded with the analysis of the oxygen consumption using non-linear models, and also using data from in vivo estimations of partial oxygen pressure at the interface cornea-lens, provided by Bonanno personal communication.

Conclusion In this paper we present ecuacio procedure for solving the non-linear partial differential equation for the position and time depending pressure p c xtfor the oxygen diffusion model of the human cornea, which is an alternative solution respect to Chhabra’s work.

We used this optimization procedure to determine optimized values of the Q c ,max and K m parameters, for a predefined set of the remaining parameters in the mknod. As for the initial condition, in order to reproduce the evolution of the pressure profile from the closed eye condition, we need to feed the stationary pressure profile in Eq. Methods The non-steady state diffusion equation that gives oxygen tension as a function of time and position, for homogeneous slab of oxygen-consuming tissue assuming a one-dimensional model for the corneais given by: As can be seen, the metabolic model Michaelis—Menton modelwith our parameters successfully reproduces experimental results for transient oxygen tension during closed-eyes contact lens wear and steady state oxygen tension over several lens transmissibilities.

It is named for Jacques Monod who proposed using an equation of this form to relate microbial growth rates in an aqueous environment to the concentration of a limiting nutrient. D and E to define:.

Monod equation – Wikipedia

However, the maximum oxygen consumption rate diminishes when the oxygen tension at the interface cornea-lens diminish, contrary to what was expected see Table 2. The rest or parameters have been taken from literature, as we point out through the text. To find out more, including how to control cookies, see here: Assuming that the cornea is a single homogeneous layer, the oxygen permeability ecuacioon the cornea will be the same regardless of the type of lens that is available on it.

Here Q c ,max eecuacion the maximum corneal oxygen-consumption rate, k c is the corneal oxygen solubility, and Mondo c is the corneal oxygen diffusion coefficient. There has been speculation that Saudi Crown Prince Mohammed Bin Salman ordered the hit but Riyadh has absolved the de facto leader of any blame Leave a Reply Cancel reply Enter your comment here This is clear evidence that the values obtained by Chhabra et al.

Insteadthe president turned it into an ambush, another media stunt Values of Q c ,max obtained fitting the curves showed in Figs.

The rate of substrate utilization is related to the specific growth rate as follows: Our results reproduce individual experiments in an acceptable manner, maintaining constant the values of the parameters K m and Dk c. Methods Assuming that the cornea is a single homogeneous layer, the oxygen permeability through the cornea will be the same regardless of the type of lens that is available on it.

Invest Ophthalmol Vis Sci. K m is the methabolic or Monod dissociation equilibrium constant, and is a parameter in the Monod kinetic model, which determines the shape of the Q c vs. Estimation of human corneal oxygen consumption by noninvasive measurements of tear oxygen tension while wearing hydrogel lenses. The non-steady state diffusion equation that gives oxygen tension as a function of time and position, for homogeneous slab of oxygen-consuming tissue assuming a one-dimensional model for the corneais given by:.

Equation 6 describes the condition where substrate utilization is proportional to substrate concentration i. This kinetics transition can be understood as a consequence of the existence of other effects into the cornea than those referred in the metabolic reactions that occur in the Krebs cycle.
