Actinic keratoses that develop on the lips are referred to as actinic cheilitis. The clinical appearance of an actinic keratosis is that of a small (several millimeters), red scaly papule or plaque, with induration and thickening of the epidermis.
1 Location: Ideally, the probe should be in close proximity to the forward or reverse primer, but should not overlap with a primer-binding site on the same strand. 2  Probes can be designed to bind to either strand of the target. 3  Melting temperature (Tm): Preferably, probes should have a Tm 6â8Â°C higher than the primers.
Figure 10b. US images obtained from the dorsal aspect with the arm in supination (a) and pronation (b) show the distal insertion site of the biceps tendon (arrows in b). Note that in supination the radial tuberosity is not seen, whereas in pronation it lies close to the probe.
