Alterações histológicas dos rins e expressão das metalotioneínas e das proteína...
Paiva, F.; Fialho, L.; Cabrita, A.S.; Pereira, A.M.F; Capela e Silva, F.The histological alterations and the expression of metallothionein (MTs) and heat shock protein (Hsp70) in the kidney of Wistar rats after thiram fungicide exposure were evaluated. Animals were distributed into three groups: standard diet group, standard diet + corn oil group and thiram group. Significant differences were found (P<0,05) in the evolution of body weight between rats in the thiram group and those ...
Physical characteristics of the eggs of red-legged partridge (Alectoris rufa) r...
Ribeiro, S.; Pereira, A.M.F.; Capela e Silva, F.; Ferraz de Oliveira, M.I.The objective of the present study was to evaluate the effects of female age (1, 2 and 3-year-old) and month of laying (March, April and May) on the physical characteristics of the red-legged partridge eggs reared in captivity. O objetivo do presente estudo foi avaliar os efeitos da idade das fêmeas (um, dois e três anos) e do mês de postura (março, abril e maio) sobre as características físic...
Assessing foraging strategies of herbivores in Mediterranean oak woodlands: a r...
Ferraz de Oliveira, M.I.; Lamy, E.; Bugalho, M.N.; Vaz, M; Pinheiro, C; Abreu, M.C.; Capela e Silva, F.; Sales-Baptista, E.Montados are agro-silvo-pastoral ecosystems, typical of the Southwest Iberian Peninsula, of high socio-economic and conservation importance,where grazing is a dominant activity. Montados are characterized by na open tree canopy of Quercus sp. and a diverse undercover of shrubs and grasslands that constitute the plant food resources for grazing animals. Plant food resources of Montados are highly variable, both ...
Analysis of pancreas histological images for glucose intolerance identification...
Rato, L.M.; Capela e Silva, F.; Costa, A.R.; Antunes, C.M.The observation in microscopy of histological sections allows us to evaluate structural differences, in pancreatic cells, between rats with normal glucose tolerance and with glucose intolerance (pre-diabetic) situation. Nevertheless, this pre-diabetic condition implies subtle changes in islets of Langerhans structure. This and the normal variability among sampled cells makes difficult the task of identifying gl...
Variations in salivary function in a rodent model of pre-diabetes.
Rodrigues, L; Mouta, R; Barra, C; Costa, AR; Capela e Silva, F; Lopes, O; Lima, M; Antunes, CM; Lamy, EDiabetes is a widespread disease representing an enormous part of the total health costs. An early diagnostic could be of extremely importance both for the understanding and prevention of this pathology. Saliva is a fluid with increasing interest as a source of biomarkers for disease diagnostic and saliva protein composition changes have already been reported for diabetic individuals. However, the studies were ...
The Influence of oral environment on diet choices in goats: a focus on saliva p...
Lamy, E; Capela e Silva, F; Ferreira, A; Baptista, ESThere is ample evidence that ruminants are capable of making choices between different foods that provide a more balanced diet that would be obtained by eating at random. In the particular case of goats, they occupy a diversity of habitats and different breeds present variability of feeding behaviors resultant from adaptations to the existent plant species. In their food search activity, individuals are faced w...
Effect of dithiocarbamate thiram on Wistar rat growth plate and articular carti...
Fialho, L; Rafael, A; Cabrita, AS; Pereira, AMF; Capela e Silva, FAvaliou-se o efeito do tirame, ditiocarbamato largamente utilizado na agricultura como antifúngico e repelente de roedores, na ossificação endocondral de mamíferos, usando, como modelo, ratos Wistar. Não foram observadas lesões na cartilagem articular, nem nas placas de crescimento, o que pode ser atribuído à dose utilizada e à duração do ensaio. A diminuição da altura da placa de crescimento nos animais aos qu...
Effects of the food contaminant semicarbazide on testicular morphology of juven...
Ramos, A; Pereira, AMF; Cabrita, AS; Capela e Silva, FO objectivo do presente trabalho foi avaliar os efeitos da semicarbazida na morfologia testicular de ratos Wistar jovens. Os animais foram tratados durante 30 dias com hidrocloreto de semicarbazida incorporado na dieta, nas concentrações de 0, 3 e 6g/kg. Os resultados obtidos revelaram uma diminuição estatisticamente significativa no diâmetro dos túbulos seminíferos, no diâmetro do lúmen dos túbulos seminíferos...
Efeitos da semicarbazida no esqueleto de ratos Wistar em crescimento.
Ramos, A; Pereira, AMF; Cabrita, AS; Capela e Silva, FThe effects of semicarbazide hydrochloride on skeletal tissues were evaluated using Wistar rats. In the animals submitted to the administration of semicarbazide, radiological examination showed bone and articular alterations with growth plates enlargement. Histological exams showed irregular patterns and proliferation of chondrocytes and excessive accumulation of extracellular matrix. Immunohistochemical exams ...
