    Abstract:

    The introduction of a preformed removable quadhelix appliance with curved rotation sheaths for insertion and removal has overcome many of the clinical problems associated with the fixed quadhelix appliance. The design, fitting and activation of the appliance are described. Various applications and modifications are discussed.

    DNA Helicases

    DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...
