The assessment of the generated temperature by the drill bit in the bone tissue
Sampaio, C.T.; Fonseca, E.M.M.; Ribeiro, J. E.; Cerqueira, R.This work aims to evaluate the generated temperature in bone tissue during a drilling process. Different clinic visits were carried out to follow-up a dental implantology and collected thermographic images for reading the temperature generated during the drilling. Simultaneously an experimental procedure was adopted with the acquisition of four blocks of Sawbones with similar properties to the trabecular and co...
Benefits of spine stabilization with biodegradable scaffolds in spinal cord inj...
Silva, Nuno; Sousa, R. A.; Fraga, J. S.; Fontes, Marco; Almeida, Hugo Leite; Cerqueira, R.; Almeida, Armando; Sousa, Nuno; Reis, R. L.; Salgado, A. J.Spine stabilization upon spinal cord injury (SCI) is a standard procedure in clinical practice, but rarely employed in experimental models. Moreover, the application of biodegradable biomaterials for this would come as an advantage as it would eliminate the presence of a nondegradable prosthesis within the vertebral bone. Therefore, in the present work, we propose the use of a new biodegradable device specifica...
Development and Characterization of a Novel Hybrid Tissue Engineering–Based Sca...
Silva, Nuno; Salgado, A. J.; Sousa, R. A.; Oliveira, João T.; Adriano, Pedro; Leite-Almeida, Hugo; Cerqueira, R.; Almeida, Armando; Mastronardi, F.Spinal cord injury (SCI) represents a significant health and social problem, and therefore it is vital to develop novel strategies that can specifically target it. In this context, the objective of the present work was to develop a new range of three-dimensional (3D) tubular structures aimed at inducing the regeneration within SCI sites. Up to six different 3D tubular structures were initially developed by rapi...

Pancreatite Hereditária na Criança
Freira, S; Lourenço, T; Cerqueira, R; Tavares, P; Pereira, G; Barata, D; Cabral, JA pancreatite hereditária define-se pela presença de alterações clínicas, bioquímicas ou radiológicas de inflamação pancreática em dois ou mais familiares com pancreatite documentada. Esta é a quarta família descrita na literatura mundial de pancreatite hereditária com mutação c.364C>T (p.R122C) do gene PRSS1. A criança que constitui o caso index teve o primeiro episódio de dor abdominal aos três anos com inter...
Study of hantavirus infection in captive breed colonies of wild rodents
Oliveira,RC; Rozental,T; Alves-Corrêa,AA; D'Andrea,PS; Schatzmayr,HG; Cerqueira,R; Lemos,ERSWild sigmondontine rodents are known to be the reservoir of several serotypes of New World hantaviruses. The mechanism of viral transmission is by aerosol inhalation of the excreta from infected rodents. Considering that the captive breed colonies of various wild mammals may present a potencial risk for hantaviral transmission, we examined 85 speciemens of Thrichomys spp. (Echimyidae) and 17 speciemens of Necto...
A new study method of microhabitat structure of small mammals
CERQUEIRA,R.; FREITAS,S. R.The variables in habitat studies are usually transformed in such a way that they become abstractions and intuition is lost. We tested a new method for the analysis of habitat using data collected in a grid laid at the "restinga de Maricá", in Rio de Janeiro State, Brazil. Thirty-seven microhabitat variables were measured at each trap station. We assume that these variables characterize the microhabitat structur...
