Choosing sheep (Ovis aries) as animal model for temporomandibular joint researc...
Angelo, D.F.; Morouço, P.; Alves, N.; Viana, T.; Santos, F.; González, R.; Monje, F.; Macias, D.; Carrapiço, B.; Sousa, R.; Cavaco-Gonçalves, S.Preclinical trials are essential to the development of scientific technologies. Remarkable molecular and cellular research has been done using small animal models. However, significant differences exist regarding the articular behavior between these models and humans. Thus, large animal models may be more appropriate to perform trials involving the temporomandibular joint (TMJ). The aim of this work was to make...

Immunohistochemistry of epidermal differentiation markers in bovine ocular squa...
Vala, Helena; Fondevila, D.; Carvalho, T.; Pinto, C.; Peleteiro, C.; Pinho, M.; Ferrer, L.The aim of this study was to evaluate the possibility of using some antibodies as diagnostic instruments, in Bovine Ocular Squamous Cell Carcinoma (BOSCC) and establishing the relationship between immunohistochemical results and the degree of differentiation. Thirty two samples from nineteen bovine ocular tumours were collected at the Matadouro Frigorífico e Industrial of Ponta Delgada, S. Miguel Island, Azores...
Immunohistochemical studies of proliferation cell markers and DNA mutation in b...
Carvalho, T.; Vala, Helena; Fondevila, D.; Pinto, C.; Peleteiro, C.; Pinho, M.; Ferrer, L.The purpose of the present study was to immunocharacterize Bovine Ocular Squamous Cell Carcinoma neoplastic cells, in terms of proliferation index and DNA damage, using two human primary antibodies anti- Ki67 antigen of the cell cycle and anti- p53. Ki67 is a nuclear antigen expressed in dividing cells during late G1, G2, S-phase and M-phase that disapears rapidly after mitosis. p53 is a tumor supressor protein...
Immunohistochemistry studies on bovine squamous cell carcinoma morphological ch...
Vala, Helena; Fondevila, D.; Carvalho, T.; Pinto, C.; Peleteiro, C.; Pinho, M.; Ferrer, L.Bovine Ocular Squamous Cell Carcinoma (OSCC) is a general designation for a group of primary neoplasias of keratinocytes arising from ocular tissues, especially the lids and particularly the third eye lid. OSCC has been diagnosed all over the world with high prevalence, being the most common bovine tumour and the one causing the most significant economic losses (Hamir & Parry, 1980; Dennis et al., 1985, Heeney ...
Estudio inmunohistoquimico de diferenciación de los carcinomas de células escam...
Vala, Helena; Fondevila, D.; Carvalho, T.; Pinto, C.; Peleteiro, C.; Pinho, M.; Ferrer, L.En el ganado bovino son frecuentes los carcinomas de células escamosas localizados en párpados y tercer párpado. En Portugal, este tumor se diagnostica con frecuencia en bovinos de las Azores, representa un 21% del total de neoplasias diagnosticadas en esta especie, la segunda después de los tumores de la vejiga de la orina. El objetivo de este trabajo ha sido conocer el origen y grado de diferenciación de esta...
