Organic Pollutant Penetration through Fruit Polyester Skin: A Modified Three-compartment Diffusion Model

Organic Pollutant Penetration through Fruit Polyester Skin: A Modified Three-compartment Diffusion Model

The surface of plants is covered by a continuous but heterogeneous cuticular membrane (CM). Serving as the first protective barrier, the uptake and transport behavior of organic pollutants at this interface continue to engage the research efforts of environmental chemist. To date, the contributions of cuticular components as a defense against the organic pollutants penetration remain unresolved...

Allergen penetration through the skin.

The skin is directly in contact with environmental molecules which are present in the air or directly in contact with the epidermis. Despite the assumption that it has a barrier role which could prevent the penetration of molecules, the skin is permeable to all substances from the low molecular weight xenobiotics to the high molecular weight proteins. Only the degree of permeability varies depe...

Influence of Dimethyl Sulfoxide as a Penetration Enhancer of Piroxicam Gel Through Biological Skin

      Piroxicam is a non-steroidal anti-inflammatory agent which has an extensive use in rheumatic disorders. Since its skin penetration is still a subject for research, the aim of this study was to evaluate the effect of dimethyl sulfoxide on percutaneous penetration of piroxicam gel formulation through skin. In this study, as a model, two types of 0.5% piroxicam new gels, so called red and gr...

Drug absorption through a cell monolayer: a theoretical work on a non-linear three-compartment model.

The subject of analysis is a non-linear three-compartment model, widely used in pharmacological absorption studies. It has been transformed into a general form, thus leading automatically to an appropriate approximation. This made the absorption profile accessible and expressions for absorption times, apparent permeabilities and equilibrium values were given. These findings allowed a profound a...
