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.
The same thing happens as Earth passes the slower moving outer planets. When we pass Jupiter, for example, the gas giant appears to reverse course in the sky for a couple of months. A schematic of how retrograde motion works when Earth (T) passes an outer planet (P) as they both orbit the sun (S).ometimes the planets appear to change direction in the sky. This retrograde motion is entirely an illusion caused by the Earth passing the slower moving outer planets. Sometimes, the planets seem to move backwards!
