IMPORTANCE Delayed healing of diabetic foot ulcers (DFUs) is known to be caused by dysregulated M1/M2-type macrophages, and restoring the balance between these macrophage types plays a critical role in healing. However, drugs used to regulate M1/M2 macrophages have not yet been studied in large randomized clinical trials. OBJECTIVE To compare the topical application of ON101 cream with use of an absorbent dressing (Hydrofiber; ConvaTec Ltd) when treating DFUs.

The assembly and characterization of dual-electrode amperometric detection for capillary electrophoresis are described. The detector consists of a disk electrode and an integrated on-capillary electrode fabricated by depositing a gold film onto the end of the separation capillary. The two electrodes are brought together, aligned, and fixed in position using a pair of acrylic plates with a straight groove on one of the plates, the same design as that of a conventional end-column detector. A portion of the on-capillary electrode is parallel-opposed to the disk electrode in a thin-layer geometry. In this region, the redox cycling established between these two electrodes significantly enhances the amperometric signals of electrochemically reversible analytes. For measurements of dopamine in pH 6.9 phosphate electrolyte with a 12.5-μm-i.d. capillary, such a configuration is 10-fold more sensitive than conventional end-column detection. The linear range exceeds 4 orders of magnitude (1.2 mM-50 nM) and the detection limit is 12 nM (4.2 amol, S/N = 3). Various modes of potential settings for the dual-electrode detection are also discussed.

Early debridement and wound coverage in Fournier's gangrene are mandatory to allow patients to return to normal life. Pedicle ALT perforator flaps provide pliable and reliable soft-tissue coverage for large perineoscrotal defects with adequate contour that result in satisfactory function and cosmesis.
