Theories of Dissolution: Diffusion Layer Model

Theories of Dissolution: Diffusion Layer Model

Dissolution, the process by which drug particles dissolve in a solvent, is explained by the diffusion layer model, a theoretical framework that simulates the absorption of oral drugs and allows us to analyze experimental data.
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...

Protein Diffusion in the Membrane

Protein Diffusion in the Membrane

Proteins show rotational as well as lateral diffusion across the membrane. The lateral diffusion of proteins was confirmed through the cell fusion experiment where mouse and human cells were fused, resulting in hybrid cells. When the human and mouse cells fused, the specific membrane proteins on human and mouse cells were marked with the red and green-fluorescent markers, respectively. Initially, the red and green fluorescence was located on the respective hemisphere of the cell. As time...

Passive Diffusion: Overview and Kinetics

Passive Diffusion: Overview and Kinetics

Passive diffusion is a critical process that allows small lipophilic drugs to cross the cell membrane along a concentration gradient. This mechanism's efficiency depends on four primary factors: the membrane's surface area, the drug's lipid-water partition coefficient, the concentration gradient, and the membrane's thickness.
When administered orally, drugs establish a substantial concentration gradient between the gastrointestinal (GI) lumen and the bloodstream, expediting...

Diffusion

Diffusion

Diffusion is the passive movement of substances down their concentration gradients—requiring no expenditure of cellular energy. Substances, such as molecules or ions, diffuse from an area of high concentration to an area of low concentration in the cytosol or across membranes. Eventually, the concentration will even out, with the substance moving randomly but causing no net change in concentration. Such a state is called dynamic equilibrium, which is essential for maintaining overall...

Background:

Diffusion dynamics are influenced by network structure and diffusion coefficients within and between layers.
Multiplex networks, with interconnected layers, present unique diffusion challenges and opportunities.

Purpose of the Study:

To quantitatively assess multiplex diffusion efficiency based on topological similarity between layers.
To explore how interlayer distance impacts global diffusion in a two-layer multiplex system.

Main Methods:

Measuring topological similarity using interlayer distance between network layers.
Rewiring one layer of a two-layer multiplex to systematically vary interlayer distance.
Analyzing diffusion processes with fixed intra- and interlayer diffusion coefficients.

Main Results:

A larger interlayer distance generally enhances global multiplex diffusion.
Topological mechanisms can be used to control diffusion processes in multiplex networks.
An algorithm was developed to identify sensitive nodes for maximizing diffusion enhancement.

Conclusions:

Interlayer distance is a critical factor for controlling diffusion in multiplex networks.
