Topical administration of hydroethanolic extract of Lawsonia inermis (henna) accelerates excisional wound healing process by reducing tissue inflammation and amplifying glucose uptake.

Several studies have reported the beneficial effects of Lawsonia inermis on wound healing, but the mechanism of action is still unknown. This study aimed to investigate the effectiveness of a new ointment formulation of hydroethanolic extract leaves of L. inermis on wound healing by gene expression of glucose transporter-1 (Glut-1) and insulin-like growth factor I (Igf-1) in Wistar rats.

Drying in porous media with gravity-stabilized fronts: experimental results.

In a recent paper [Yiotis et al., Phys. Rev.

Analytical solutions of drying in porous media for gravity-stabilized fronts.

We develop a mathematical model for the drying of porous media in the presence of gravity. The model incorporates effects of corner flow through macroscopic liquid films that form in the cavities of pore walls, mass transfer by diffusion in the dry regions of the medium, external mass transfer over the surface, and the effect of gravity. We consider two different cases: when gravity opposes liquid flow in the corner films and leads to a stable percolation drying front, and when it acts in the opposite direction.
