EFICÁCIA DE COLOIDES VS CRISTALOIDES NA REPOSIÇÃO VOLÉMICA A NÍVEL HEPÁTICO EM ...
Pina R, Vala H; Cruz R, Venâncio C; Silva A, Garcia C; Ortiz A, Ferreira DApesar dos avanços na sua abordagem terapêutica, a hemorragia severa continua a ser a principal causa de morbilidade e mortalidade em animais vítimas de trauma ou sujeitos a intervenção cirúrgica. A causa das lesões decorrentes, ou da morte consequente, deve-se ao deficit de volume de fluidos intravasculares e subsequente desenvolvimento do estado hipovolémico.O controlo da hipovolémia passa pela resolução da h...
Apoptosis as a prognostic marker in prediction of renal injury, after acute ble...
Cruz, R.; Vala, H.; Machado, A.; Venâncio, C.; Mesquita, J.; Silva, A.; Ortiz, A. L.; Ferreira, D.Objectives: The aim of this study is to identify and quantify apoptosis in renal tissue, using a biochemical marker (TUNEL) in a pig haemorrhagic model, after intravascular volume replacement with Ringer's lactate RL) or Hydroxyethylstarch (HES) 130/0.4) solutions. Methods: 18 Large White pigs underwent total intravenous anaesthesia (TIVA) with propofol and remifentanil. 25 ml/kg of arterial blood were removed ...
Small intestine apoptosis evaluation after haemorrhage followed by volume repla...
Ortiz, A.; Vala, Helena; Garcia, C.; Cruz, R.; Venâncio, C.; Silva, A.; Ferreira, D.Apoptosis plays a key role in intestinal injury, as response to ischemia. Furthermore, reperfusion exacerbates abnormal intestinal apoptosis. In this study, the apoptotic index (AI) in the small intestine after haemorrhage and volume replacement with Ringer´s solution was evaluated, in a pig model
Histological evaluation of the spleen after acute bleeding followed by volume r...
Cabral, M.; Ortiz, A.; Venâncio, C.; Mesquita, J.; Nóbrega, C.; Silva, A.; Vala, Helena; Ferreira, D.Spleen is important for many hematopoietic and immunological functions, namely in hemodynamic compensation during hemorrhagic shock, with a crucial role in restoring blood volume in situations of acute haemorrhage. Also, the administration of physiological solutions is of great importance for the correction of circulating volume, avoiding complications due to hypovolemia. The aim of this study was to eval...

Ortiz, A.; Vala, H.; Garcia, C.; Cruz, R.; Venâncio, C.; Silva, A.; Ferreira, D.FEDER funds trough the COMPETE Program, and by national funds from Portuguese Foundation for Science and Technology, under the project COMPETE: FCOMP-01-0124-FEDER-009525 ; Apoptosis plays a key role in intestinal injury, as response to ischemia. Furthermore, reperfusion exacerbates abnormal intestinal apoptosis. In this study, the apoptotic index (AI) in the small intestine after haemorrhage and volume replac...
Renal apoptosis signalling in a pig haemorrhagic model, after volume replacemen...
Cruz, R.; Vala, Helena; Machado, A.; Venâncio, C.; Mesquita, Jr; Silva, A.; Ortiz, A.; Ferreira, D.TUNEL staining is one of the most frequently used method to detect apoptosis in renal tissues. The aim of this part of the study was to evaluate kidney damage after acute bleeding and volume replacement, with a colloid or a crystalloid, in a pig model
Evaluation and characterization of intestinal oedema in pigs
Ortiz, A. L.; Vala, Helena; Silva, A.; Venâncio, C.; Garcia, C.; V, D.Introduction When characterizing small intestine early lesions in studies concerning intestinal hypoperfusion in pigs, authors faced a significant difficulty when trying to standard the oedema grading to allow an accurate comparison between groups. Therefore, specific alterations were assumed to characterize grade1 (G1), grade2 (G2) and grade3 (G3) oedema. Material and Methods Eighteen Large White pigs underwen...
Familial C4B deficiency and immune complex glomerulonephritis
Soto, K; Wu, Y; Ortiz, A; Aparício, S; Yu, CHomozygous complement C4B deficiency is described in a Southern European young female patient with Membranoproliferative Glomerulonephritis (MPGN) type III characterized by renal biopsies with strong complement C4 and IgG deposits. Low C4 levels were independent of clinical evolution or type of immunosuppression and were found in three other family members without renal disease or infections. HLA typing reveale...
Custom power interfaces for renewable energy sources
Rolim, L. G. B.; Ortiz, A.; Aredes, Maurício; Pregitzer, Ricardo G.; Pinto, J. G.; Afonso, João L.Interface converters for renewable energy sources can be regarded as custom power devices. Thus they can be designed and operated so as to improve power quality at their connecting locations. This paper presents examples of converter designs based on p-q theory for different applications. Modeling, simulations and experimental results are given for converter prototypes operating either as active power filter (A...
Grau de preferência e índice de valor forrageiro das pastagens nativas consumid...
SANTOS, S. A.; COSTA, C.; POTT, A.; CRISPIM, S. M. A.; SORIANO, B. M. A.; ALVAREZ, J. M.; ORTIZ, A. G.Os bovinos são criados em sistema de pastejo contínuo no Pantanal, onde tem a oportunidade de selecionar as espécies forrageiras, cuja qualidade das pastagens depende da proporção das espécies forrageiras preferidas. Este trabalho tem como objetivo avaliar o grau de preferência das forrageiras, bem como avaliar o índice de valor forrageiro das áreas de campo limpo e baixadas da fazenda Nhumirim, subregião da Nh...
