We made some measurements from the region of the symphysis menti in 308 dried mandibles; 247 belong to the collection of the cranial museum of the discipline of Anatomy of the UNIFESP- Escola Paulista de Medicina- EPM and 61 belong to the didactic laboratory of the discipline of Anatomy from the Faculdade de Odontologia de Araraquara- UNESP, Brasil. On the dentate mandibles, the highest value founded was of 43,46 mm and the lowest of 22,67 mm. On the edentate mandibles, the highest value founded was of 37,24 mm and the lowest of 6,22mm. We hope that with the following discoveries we could contribute to a better knowledge of the symphysis menti region, not only to the professionals in Surgery and Implantology areas, but the industrials of related areas, to the confection of instruments used in these practices. © 2007 Sociedad Chilena de Anatom•br>.

Calcareous Albian-Cenomanian strata in the Potiguar basin yield a number of microfossils, among which are calcareous algae (Dasycladales and Corallinales). This data, together with an inventory of previous discoveries, enabled the discussion of their biogeography. These benthic organisms probably came from the early Central Atlantic Ocean through its northwestern neck between Africa and South America and thus reached the early South Atlantic platforms.

Among remarkable discoveries concerning propolis, such as antifungal, antiviral, and antioxidant activities, its anti-inflammatory, and mainly its antibacterial, properties deserve special attention when skin wound healing is concerned. Based on this and knowing the distinctive performance of bacterial (BC) membranes on wound healing, in this work it is proposed to demonstrate the potent antimicrobial activity and wound healing properties of a novel propolis containing biocellulose membrane. The obtained propolis/BC membrane was able to adsorb propolis not only on the surface, but also in its interstices demonstrated by scanning electron microscopy, X-ray diffraction, Fourier transform infrared (FT-IR) spectroscopy, and thermogravidimetric assays. Additionally, the polyphenolic compounds determination and the prominent antibacterial activity in the membrane are demonstrated to be dose dependent, supporting the possibility of obtaining propolis/BC membranes at the desired concentrations, taking into consideration its application and its skin residence time. Finally, it could be suggested that propolis/BC membrane may favor tissue repair in less time and more effectively in contaminated wounds. © 2013 Hernane da Silva Barud et al.
