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.
Reverse DNS. Reverse DNS is IP address to domain name mapping-the opposite of forward (normal) DNS which maps domain names to IP addresses. Reverse DNS is separate from forward DNS.he name of the PTR-record is the IP address with the segments reversed + .in-addr.arpa. For example the reverse DNS entry for IP 1.2.3.4 would be stored as a PTR-record for 4.3.2.1.in-addr.arpa.
