BILATERAL MAXILLARY SINUS FLOOR AUGMENTATION WITH TISSUE-ENGINEERED AUTOLOGOUS OSTEOBLASTS AND DEMINERALIZED FREEZE-DRIED BONE

Bilateral maxillary sinus floor augmentation with tissue-engineered autologous osteoblasts and demineralized freeze-dried bone

The pneumatization of the maxillary sinus often results in a lack of sufficient alveolar bone Patches for implant placement.In the last decades, maxillary sinus lift has become a very popular procedure with predictable results.Sinus floor augmentation procedures are generally carried out using autologous bone grafts, bone substitutes, or composites

Trophic and spatial complementarity on seed dispersal services by birds, wild mammals, and cattle in a Mediterranean woodland pasture

Most Foundation earth surfaces have undergone intensive land-use changes, creating habitat mosaics.Seed dispersal by animals is a crucial process in such mosaics, but community-wide studies comparing the functional complementarity and response to man-imposed habitat heterogeneity are rare.Here, we investigate the trophic and spatial seed dispersal

Dispersion and efficiency engineering of metasurfaces

Metasurfaces, ultrathin two-dimensional arrays of artificially engineered meta-atoms, can impart spatially varying changes towards the incident electromagnetic wave and provide versatile functionalities once unprecedented in sub-wavelength thick natural materials.The wavefront manipulation by metasurfaces usually benwa-balls arises from the strong
