Partially encased beams (PEB) are composite steel and concrete elements that present several advantages with respect to steel bare elements. This paper presents a set of experimental tests developed using two different beam lengths and two different shear conditions between stirrups and web (W – welded and NW – not welded), at high temperature (200, 400, 600 ºC) and room temperature. The composite section was b...
The prevention of hepatitis B is important, since it is responsible for significant morbidity and mortality around the world. Unfortunately, hepatitis B vaccine does not always induce protective immunity. The lack of immune response to vaccine (non-responders) can depend on individual characteristics. The objective of this study was to correlate the CD26/DPPIV cellular expression and DPPIV serum activity with H...
Sarcoidosis is a systemic disease of unknown aetiology, morphologically characterized by well-formed epithelioid granulomas, which show little or no central necrosis. These may be present in any organ or tissue. The lung is the most frequently and prominently involved target. The granuloma is often very sharply demarcated from the adjacent tissue and is surrounded by a mantle of lymphocytes, which mediate lysis...

Fibrous dysplasia is a non-neoplastic bone lesion of unknown etiology. It is a non-encapsulated lesion occuring mainly in young subjects, usually in the maxilla, and showing replacement of the normal bone by cellular fibrous tissue containing islands or trabeculae of metaplastic bone. Fibrous dysplasia is usually monostotic, but may occasionally be part of a polyostotic process. The polyostotic lesion may occur...
Em estudos anteriores, pudemos constatar que nos indivíduos VIH negativos a gravidade da tuberculose pulmonar (TP) era modulada pelos perfis linfocitários Th1/Th2 nas áreas lesadas: predominio de Th1 (30.9±14.3/24.3±9.7% - p<0.04) e γ-INF (21.2±3.4/7.3±1.8% p<0.0002) e menores níveis de IL 4 (5.4±1.7/10.3±1.3% p<0.0004) no LLBA das formas ligeiras, em relação às mais graves. No sangue, curiosamente, existia...
No contexto epidemiológico da tuberculose (TB) que presentemente assola o nosso país destaca-se o número progressivamente crescente de formas clínicas graves e que atingem indivíduos aparentemente imunocompetentes. Na tentativa de contribuir para o esclarecimento dos fenómenos que na intimidade do pulmão profundo comandam as perturbações patogénicas que ocorrem nestas situações, estudámos 35 doentes portadores ...
