Congenital pancreas malformations: a clinical case report
Bento, A; Baptista, H; Oliveira, FJOBJECTIVE: This study aimed to review the congenital malformation known as agenesis of the dorsal pancreas (ADP) and other pancreatic birth defects, based on a rare and exemplary clinical case of pancreatic malformations. The intent was to review the latest information published in the national and international literature on pancreatic birth defects, and to investigate the diversity of clinical presentations o...
HDPE/mesoporous silica nanocomposites by in-situ polymerisation: structural det...
Bento, A.; Lourenço, J. P.; Fernandes, A.; Pérez, E.; Cerrada, MarÃa L.; Ribeiro, M. R.Mesoporous silicas exhibit stable three-dimensional structures, made of ordered channels with well-defined geometries and dimensions at nanometer scale, able to host intercalation reactions.
New HDPE/MCM41 nanocomposites with improved mechanical performance: synthesis a...
Bento, A.; Lourenço, J. P.; Fernandes, A.; Pérez, E.; Cerrada, MarÃa L.; Ribeiro, M. R.Ordered mesoporous silicas with a channel structure of well - defined geometries and dimensions at nanometer scale are excellent candidates to host intercalation reactions. In recent y ears, our research group has shown that mesoporous silicas of the M41S class combined with metallocene complexes give rise to excellent supported catalysts for ethylene polymerisation. Due to the support characteristics, the reac...

Jejuno-jejunal invagination caused by epithelioid sarcoma: a case report
Bento, A; Baptista, H; Pinheiro, C; Martinho, FINTRODUCTION: Jejuno-jejunal invagination is a rare condition and is usually caused by a benign lesion. We describe the case of a patient with a jejunal epithelioid sarcoma. Epithelioid sarcoma is a rare histologic subtype of sarcoma and few cases have been published. CASE PRESENTATION: A 70-year-old Caucasian man presented with vomiting and anemia. A jejuno-jejunal invagination was diagnosed and the patient un...
MCM-41 as Nanofiller in Polyethylene Hybrid Materials
Ribeiro, M. R.; Campos, João M.; Bento, A.; Lourenço, J. P.; Pérez, E.; Cerrada, María L.Mesoporous MCM-41 exhibits a stable framework structure, well-defined nanopores and a large surface area. When combined with metallocene polymerisation catalyst, these mesoporous materials, provide a unique route for preparing polyolefin-based nanocomposites by in situ polymerisation.
Genetic identification in endodontic treated tooth root
Corte-Real, A. T.; Anjos, M. J.; Andrade, L.; Carvalho, M.; Serra, A.; Bento, A. M.; Oliveira, C.; Batista, L.; Corte-Real, F.; Vieira, D. N.The tooth is an important sample in adverse forensic conditions. Its morphology and histology contributes for the preservation of the cellular components. ; http://www.sciencedirect.com/science/article/B8JHP-4SBRTWX-V/1/4edd71a84d252ef01f799c324b50a993

Atividade antinociceptiva do extrato etanólico do fruto de Solanum acanthodes H...
Bento,A.F.; Azevedo,M.S.; Luiz,A.P.; Moura,J.A.; Santos,A.R.S.Solallum acanthodes. popularmente conhecido como "jurubeba", foi estudada com o objetivo de avaliar suas propriedades antinocicept i vas nos modelos de nociccpção induzida pela I'ormalina e glutamato. Para isto foi utilizado o extrato elanólico dos frutos (EES) da planta. Os resultados apresentaram altos níveis de significância, demonstrando o potencial analgésico de S. acanthodes.
Thermal lens temperature scanning for quantitative measurements in complex fluids
Rohling,J. H.; Mura,J.; Pereira,J. R. D.; Palangana,A. J.; Medina,A. N.; Bento,A. C.; Baesso,M. L.; Miranda,L. C. M.In this work thermal lens spectrometry is applied to investigate the thermo-optical properties of complex fluids as a function of the temperature. The method is applied in poly(vinyl chloride), in polycarbonate and in lyotropic liquid crystals as the testing samples. The focus of the discussion will be in the temperature range where the phase transitions occur. The perspective of future studies in this area wil...
