Chimeric adenovirus-based herpes zoster vaccine with the tPA signal peptide elicits a robust T-cell immune response.

Herpes zoster (HZ), or shingles, is caused by reactivation of the varicella-zoster virus (VZV), which remains latent in the sensory ganglia until immunity wanes with age. The representative HZ vaccine, Shingrix is efficacious but causes side effects due to vaccine adjuvants. Therefore, the development of highly efficacious vaccines with minimal side effects is required.

Morphogenesis of the peri-implant mucosa: a comparison between flap and flapless procedures in the canine mandible.

Objective: Although it has been shown that the exclusion of the mucoperiosteal flap can prevent postoperative bone resorption associated with flap elevation, there have been only a few studies on the peri-implant mucosa following flapless implant surgery. The purpose of this study was to compare the morphogenesis of the peri-implant mucosa between flap and flapless implant surgeries by using a canine mandible model.

Study Design: In six mongrel dogs, bilateral edentulated flat alveolar ridges were created in the mandible.
