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.
Arrows along fault indicate relative or apparent direction of lateral movement. Arrow on fault indicates direction of dip. Low angle fault (barbs on upper plate). Fault surface generally dips less than 45Â° but locally may have been subsequently steepened. On offshore faults, barbs simply indicate a reverse fault regardless of steepness of dip.
