As demonstrated by the 10xSTATGFP pathway activity reporter, cells within the trough of the medial and proximal folds have high levels of JAK/STAT signalling (Fig. 7A,B, green).
The in vitro drug transport studies were performed in Franz diffusion cells across folded epidermis, which is used as a model for the proximal nail fold.
Iontophoresis across the proximal nail fold could be developed as a potential method to target drugs to nail matrix.
Iontophoresis of terbinafine across the proximal nail fold was assessed using excised cadaver toe model as well.

The main objective of the present study was to investigate the plausibility of iontophoretic delivery of drugs to the nail matrix via proximal nail fold.
Good insertion of the nail base into the sack bottom of the proximal nail fold is very important to prevent a dead space that may cause adherence between the nail matrix and eponychium and subsequent ungual dystrophy.
Clinical assessment also included measuring new, clear nail growth by placing a cut at the proximal nail fold and measuring nail growth from that point onward.
This suggested that the recognition of the entire proximal Ub fold is required for the linkage specificity of these DUBs, which was consistent with the involvement of, for example, UBDs.
Serosanginous crusting/exudate and granulation tissue also involved the proximal nail folds.
Consequently the identification of the redox boundary within F2 folds elsewhere in the Curnamona Province – particularly when located proximal to F3 fold hinges, which place the mineralised zones into structurally favourable locations – provide good targets for future mineral exploration.
