Bi-layered collagen nano-structured membrane prototype collagen matrix CM-10826 for oral soft tissue regeneration: an in vivo ultrastructural study on 13 patients. J Biol Regul Homeost Agents. 2019 Jan-Feb;33(Suppl 1 [integer]):29-41 Authors: De Santis D, Gelpi F, Castellani R, Palumbo C, Ferretti M, Zanotti G, Zotti F, Montagna L, Luciano U, Marconcini S, Tacchino U, Manuelli M, Nocini R, Nocini PF, Albanese M Abstract A new developed collagen matrix CM-10826 (CM) of porcine origin designed to be used as oral soft tissue substitute was investigated before and after implantation by light microscopy (LM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). In a case series biopsy specimens were harvested from thirteen patients at 10, 20, 30, 43 days after abutment surgery for uncovering dental implants. The in vivo histological evaluations of each patient were performed via micro-coring of newly formed oral mucosa in the area covered by CM (test side) or left uncovered (control). Results showed that CM can be integrated in connective and epithelial tissues within 10 days, can be completely resorbed within 20 days and it is able to reduce inflammatory infiltrates and to stimulate both fibroblast/epithelial cell proliferation and neo-angiogenesis. Generally it seems to be superior in promoting soft tissue healing compared to that induced by secondary intention healing. Furthermore, it is able to act as a scaffold for soft-tissue r...

Microstructure analysis revealed that BNBZN sample demonstrates global pseudocubic structure with locally distorted structures. Electric measurements showed that the sample coexists of two types of polar nanoregions (PNRs) with different coupling ability, and behaves as er...

The foaming ability significantly increased after ultrasound treatment and the highest foaming ability (99.13%) was achieved at 60 d compared to untreated egg white (29.75%). This improvement was ascribed to the increased free sulfhydryl content and surface hydrophobicity, indica...

AbstractAcute lower respiratory tract infection is a major health problem that affects more than 15% of the total population of Saudi Arabia each year. Epidemiological studies conducted over the last three decades have indicated that viruses are responsible for the majority of these infections. The epidemiology of respiratory viruses in Saudi Arabia is proposed to be affected mainly by the presence and mobility of large numbers of foreign workers and the gathering of millions of Muslims in Mecca during the Hajj and Umrah seasons. Knowledge concerning the epidemiology, circulation pattern, and evolutionary kinetics of respi...
