[The impact of ultrasonic dental hygiene procedures on the bonding strength of restorations].

Ultrasonic calculus scaling has become a common oral hygiene procedure in patients with composite restorations, dental veneers, orthodontic brackets. The aim of the study was to evaluate in vitro the influence of the EMS-ultrasonic system scaling on the flowable composite bond strength to the tooth enamel, dentine, and e-max ceramic. The samples were divided into three groups: 1 group (composite bonded to enamel), 2 group (composite bonded to dentine), 3 group (composite bonded to e-max ceramic).

[Production of purified human recombinant alpha2b-interferon].

Technology for producing biologically active recombinant alpha2b-interferon is based on creating a bacterial producer strain containing the cDNA of human interferon alpha. The authors have obtained two producers of recombinant alpha2b-interferon, the synthesis of the target protein in them occurs in the inclusion bodies. The schemes of isolation and purification of biologically active recombinant alpha2b-interferon have been developed.
