A multicentre, randomized, double-blind, crossover study was designed to investigate the effects of prednisone on allergic and irritant patch test reactions. 24 subjects with known allergy to nickel were recruited and patch tested with a nickel sulfate dilution series in
The efficacy of a 15% (w/w) mixture of octanoic, nonanoic and decanoic acids in light mineral oil to repel Culicoides biting midges (Diptera; Ceratopogonidae) was determined in three replicates of a 4 × 4 Latin square design under South African

The responses to 12-HETE in normal human skin have been investigated by means of intradermal and topical administration in 15 subjects. Intradermal infusion of 12-HETE produced a neutrophil polymorphonuclear and mononuclear infiltrate in the dermis. Topical administration resulted in a

Irritant contact dermatitis may be induced by many chemicals and has a far greater incidence than allergic contact dermatitis. Despite this, it receives relatively little attention and its pathogenesis remains poorly understood. To gain a greater understanding of the interaction

Pseudomonas putida KT2440 grew on glucose at a specific rate of 0.48 h(-1) but accumulated almost no poly-3-hydroxyalkanoates (PHA). Subsequent nitrogen limitation on nonanoic acid resulted in the accumulation of only 27% medium-chain-length PHA (MCL-PHA). In contrast, exponential nonanoic acid-limited
