Carbon nanotubes are highly versatile materials; new applications using them are continuously being developed. Special attention is being dedicated to the possible use of multiwalled carbon nanotubes in biomaterials contacting with bone. However, carbon nanotubes are also controversial in regards to effects exerted on living organisms. Carbon nanotubes can be used to improve the tribological properties of polym...
Haematological (WBC, RBC, Hgb and Hct) and genotoxicity (MNT) parameters, hepatic enzymatic activities (GST, GPx and GR), and a histopathological evaluation of liver, kidneys and gonads were assessed as general biomarkers of metal pollution in the shrew Crocidura russula inhabiting a pyrite mining area. Specimens exposed to metals presented a few significant alterations when compared with reference animals: GST...
Neste trabalho experimental procedeu-se à medição da espessura e à caracterização histológica de lesões ateroscleróticas, em suínos de raça Alentejana, procurando-se estabelecer uma relação entre estas e os valores dos parâmetros sanguíneos associados ao desenvolvimento deste processo patológico. As concentrações plasmáticas de triacilgliceróis, fosfolípidos, colesterol total, colesterol livre, LDLc e HDLc fora...
