Tissue engineering: Using collagen type i matrix for bone healing of bone defects

Among the many tissues in the human body, bone has been considered as a powerful marker for regeneration and its formation serves as a prototype model for tissue engineering based on morphogenesis. Therefore, collagen type I is one of the most useful biomaterials used in tissue engineering as extracellular matrix components capable to promote bone healing. The literature reveals excellent biocompatibility and safety due to its biological characteristics, such as biodegradability and weak antigenicity, making collagen type I the primary resource in medical applications. Thus, it was also used for tissue engineering including skin replacement, bone substitutes, and artificial blood vessels and valves. The authors describe the treatment of an abscessed apical periodontal cyst and show good outcomes of bone healing, using tissue engineering, as collagen type I matrix. © 2013 by Mutaz B. Habal, MD.

Facial growth evaluation of complete unilateral cleft lip and palate operated patients: a cleft reference center in Paraíba, Brazil, using the GOSLON yardstick

Objectives: To evaluate the surgical outcomes of patients with complete unilateral cleft lip and palate (CUCLP) operated on by a single surgeon of the cleft reference center of the Lauro Wanderley University Hospital at the Federal University of Paraiba. Methods: Forty-four individuals' dental casts diagnosed with CUCLP, born between 1995 and 2002, mean age of 11 years, were evaluated by three calibrated orthodontic specialists and scored by the Great Ormond Street, London and Oslo (GOSLON) yardstick on two occasions. The scores were compared with those observed in other centers around the world. The Kappa test was applied to evaluate the intra- and inter-examiner agreement. Descriptive statistics was applied for the GOSLON yardsticks core. Results: The mean GOSLON score was 2.75. For the GOSLON yardstick, 43.2 % of the sample presented scores 1 and 2, 31.8 % had score 3, and 25 % were with scores 4 and 5. There was very good intra- and inter-examiner Kappa agreement in the application of the GOSLON yardstick. Conclusions: The data suggest favorable outcomes, with 75 % of cases with no need of orthognathic surgery. The Kappa values confirmed the high reproducibility of the GOSLON yardstick. © 2013 Springer-Verlag Berlin Heidelberg.

Topological K-classification of finitely determined map germs

We consider smooth finitely C 0-K-determined map germs f: (ℝn, 0) → (ℝp, 0) and we look at the classification under C 0-K-equivalence. The main tool is the homotopy type of the link, which is obtained by intersecting the image of f with a small enough sphere centered at the origin. When f -1(0) = {0}, the link is a smooth map between spheres and f is C 0-K-equivalent to the cone of its link. When f -1(0) ≠ {0}, we consider a link diagram, which contains some extra information, but again f is C 0-K-equivalent to the generalized cone. As a consequence, we deduce some known results due to Nishimura (for n = p) or the first named author (for n < p). We also prove some new results of the same nature. © 2012 Springer Science+Business Media Dordrecht.
