World J Stem Cells 2019 Feb;11(2):124-146

InGeneron GmbH, Munich 80331, Germany.

Background: Novel strategies are needed for improving guided bone regeneration (GBR) in oral surgery prior to implant placement, particularly in maxillary sinus augmentation (GBR-MSA) and in lateral alveolar ridge augmentation (LRA). This study tested the hypothesis that the combination of freshly isolated, unmodified autologous adipose-derived regenerative cells (UA-ADRCs), fraction 2 of plasma rich in growth factors (PRGF-2) and an osteoinductive scaffold (OIS) (UA-ADRC/PRGF-2/OIS) is superior to the combination of PRGF-2 and the same OIS alone (PRGF-2/OIS) in GBR-MSA/LRA.

Case Summary: A 79-year-old patient was treated with a bilateral external sinus lift procedure as well as a bilateral lateral alveolar ridge augmentation. Read More

The cranio-mandibular complex of the nightjar Systellura longirostris (Aves, Caprimulgiformes): functional relationship between osteology, myology and feeding.

Zoology (Jena) 2019 02 13;132:6-16. Epub 2018 Nov 13.

Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Buenos Aires, Argentina; Instituto de Física Enrique Gaviola (IFEG), UNC, CONICET, Córdoba, Argentina. Electronic address:

Here we address the morphology of the cranial musculoskeletal in the South American Band-winged nightjar (Systellura longirostris, Caprimulgiformes, Aves) with the focus upon in how the mouth closure and opening mechanism is. Bony characters such as the thinness of the interorbital septum and the reduction of the postorbital process co-assist the location of large eyes, although correlations between eye size brain mass and body mass revealed that the Band-winged nightjar's eye is bigger than expected. The reduction of the processus orbitalis of the os quadratum would allow the great mouth opening given by a large maxillary protraction. Read More

WNT10A variants in relation to nonsyndromic hypodontia in eastern Slovak population.

J Genet 2018 Dec;97(5):1169-1177

Department of Biology, Faculty of Humanities and Natural Sciences, University of Presov, Presov, Slovakia.

Nonsyndromic hypodontia is a congenital absence of less than six permanent teeth, with a most common subtype maxillary lateral incisor agenesis (MLIA). Mutations in several genes have been described in severe tooth agenesis. The aim of this study was to search for the variants in wingless-type MMTV-integration site family member (), paired box 9 () and axis inhibitor 2 () genes, and investigate their potential role in the pathogenesis of non-syndromic hypodontia.
