The liquid-liquid diffusive extraction of hydrocarbons from a North Sea oil using a microfluidic format.

Extraction of a GC-amenable hydrocarbon fraction from oil by liquid-liquid diffusion across a laminar interface can be performed in a microfluidic format. Analysis of figures of merit, determined using standard analytical techniques, show this method to be an effective new tool for rapidly processing small quantities of oil and petroleum for GC analysis. Methods based upon similar microsystems devices could find widespread use in a variety of fields, including those associated with organic geochemistry and oil exploration and production, where the manipulation of petroleum constituents (greater than C14) is necessary for analytical purposes.

Iatrogenic phytophotodermatitis resulting from herbal treatment of an allergic contact dermatitis.

Phytophotodermatitis commonly occurs in skin exposed to sunlight after contact with plants containing furocoumarins. While it is recognized that the consumption of plants or vegetables containing furocoumarins can potentially trigger a phytophotodermatitis, there have been no reports to date of a phytophotodermatitis triggered by an ingested herbal remedy. We describe the case of a 56-year-old farmer who developed an extensive photo-induced dermatitis after ingesting a herbal decoction prescribed for his chronic hand dermatitis.
