Permeation of skin with (C₆₀) fullerene dispersions [PDF]

Engineering in Life Sciences, 2017
Dispersions in transcutol/isopropyl myristate make C60 fullerene molecules suitable for transdermal delivery. We found that C60 can successfully permeate the skin using pig skin in Franz diffusion cells. Molecular dynamics simulations and transmission electron microscopy confirmed these observations.

Characterization of UF membranes : membrane characteristics and characterization techniques [PDF]

, 1991
In this paper a new method is presented for the determination of the skin thickness of asymmetric ultrafiltration membranes. The method is based on the use of well-defined, uniformly sized colloidal gold particles, permeated from the sublayer side of the

Biodegradable hollow fibres for the controlled release of hormones [PDF]

, 1987
Poly(l-lactide), (PLLA), hollow fibres were prepared using a dry-wet phase inversion spinning process. The effect of several spinning parameters (i.e. bore medium flow rate, spinning dope extrusion rate, fibre take-up rate, and spinning height) on the ...

A rationale for the preparation of asymmetric pervaporation membranes [PDF]

, 1985
Pervaporation is carried out primarily with homogeneous membranes. An improvement in permeation rate can be achieved by using asymmetric or composite membranes. In order to maintain a high selectivity, very dense top layers are needed.

Evaluation of percutaneous permeation of repellent DEET and sunscreen oxybenzone from emulsion-based formulations in artificial membrane and human skin

Acta Pharmaceutica Sinica B, 2014
Insect repellent DEET and sunscreen ingredient oxybenzone play an essential role in minimizing vector-borne diseases and skin cancers. The purpose of this study was to investigate the effects of emulsion type, addition of thickening agent and droplet ...

Topical Treatment for Cutaneous Leishmaniasis: Dermato-Pharmacokinetic Lead Optimization of Benzoxaboroles. [PDF]

, 2018
Cutaneous leishmaniasis (CL) is caused by several species of the protozoan parasite Leishmania, affecting an estimated 10 million people worldwide. Previously reported strategies for the development of topical CL treatments have focused primarily on drug

The Phenion (R) Full-Thickness Skin Model for Percutaneous Absorption Testing [PDF]

, 2010
In recent years many efforts have been made to replace dermal toxicity testing of chemicals in the animal by in vitro assays. As a member of a German research consortium, we have previously contributed to the validation of an in vitro test protocol for ...

Water permeation through stratum corneum lipid bilayers from atomistic simulations [PDF]

, 2009
Stratum corneum, the outermost layer of skin, consists of keratin filled rigid non-viable corneocyte cells surrounded by multilayers of lipids. The lipid layer is responsible for the barrier properties of the skin.
