Efeitos do diluidor na viabilidade espermática pós-criopreservação em tourinhos...
Felipe-Silva,A.S; Vale Filho,V.R; Ferreira,M.B.D; Correa,G.S.S; Silva,M.A; Veras,M.M; Andrade,V.JProcedeu-se à criopreservação do sêmen de oito tourinhos Gir Leiteiro, com idade média de 25 meses, pré-selecionados para elevada pontuação (média 84,4±5,6) na classificação andrológica por pontos (CAP), em dois diferentes diluidores: um à base de lactose-gema-glicerol e outro à base de lecitina de soja. As curvas de resfriamento e congelação foram padronizadas com o auxílio da máquina CRYOGEN®. Os parâmetros p...
Disponibilidade de Cu, Pb e Zn nas áreas mineiras de Canal Caveira e São Doming...
Santos, E.S.; Abreu, M.M.; Ferreira, M.B.; Magalhães, M.C.F.Several mining areas are abandoned in the Iberian pyrite belt (IPB) leading to important points of environmental contamination. The potential and immediate environmental risk and impact on public health of hazardous elements from soil can be estimated from availability analysis. The aim of this study was to evaluate the availability of Cu, Pb and Zn in São Domingos and Canal Caveira mining areas located in the ...
Familial osteopetrosis in Agouti paca: report of nine cases
Coutinho,P.S.; Ocarino,N.M.; Ferreira,M.B.; Resende,R.; Silva,V.L.; Guedes,R.M.C.; Serakides,R.Nine cases of familial osteopetrosis were studied in Agouti paca rodents maintained in captivity. Animals were distributed in three groups depending on the severity of their skeletal lesions. Based upon clinical, radiological, and microscopic findings, it was concluded that one animal had level I lesions, three animals had level II lesions, and five animals had level III osteopetrosis and osteonecrosis. Through...
Interaction between repeated restraint stress and concomitant midazolam adminis...
Silveira,P.P.; Xavier,M.H.; Souza,F.H.; Manoli,L.P.; Rosat,R.M.; Ferreira,M.B.C.; Dalmaz,C.Emotional changes can influence feeding behavior. Previous studies have shown that chronically stressed animals present increased ingestion of sweet food, an effect reversed by a single dose of diazepam administered before testing the animals. The aim of the present study was to evaluate the response of animals chronically treated with midazolam and/or submitted to repeated restraint stress upon the ingestion o...
Increased training prevents the impairing effect of intra-amygdala infusion of ...
Roesler,R.; Quevedo,J.; Rodrigues,C.; Madruga,M.; Vianna,M.R.M.; Ferreira,M.B.C.Intra-amygdala infusion of the non-N-methyl-D-aspartate (NMDA) receptor antagonist 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) prior to testing impairs inhibitory avoidance retention test performance. Increased training attenuates the impairing effects of amygdala lesions and intra-amygdala infusions of CNQX. The objective of the present study was to determine the effects of additional training on the impairing...
Involvement of hippocampal NMDA receptors in retention of shuttle avoidance con...
Roesler,R.; Kuyven,C.R.; Kruel,A.V.S.; Quevedo,J.; Ferreira,M.B.C.The purpose of this research was to evaluate the role of hippocampal N-methyl-D-aspartate (NMDA) receptors in acquisition and consolidation of memory during shuttle avoidance conditioning in rats. Adult male Wistar rats were surgically implanted with cannulae aimed at the CA1 area of the dorsal hippocampus. After recovery from surgery, animals were trained and tested in a shuttle avoidance apparatus (30 trials,...
Systemic effects of inhaled corticosteroids. Various pending questions.
Ferreira, M B; Serviço de Medicina III, Hospital de Santa Maria, Faculdade de Medicina de Lisboa.; Pedro, E; Barbosa, M A; Carlos, A GInhaled steroids play a central and undisputed role in the management of Bronchial Asthma, since inflammation has been recognised as the main physiopathological mechanism in this disease. Indeed, the earlier introduction of inhaled steroids in the therapy of Bronchial Asthma is currently being recommended by several authors. However, accompanying the much broader use of these drugs, concerns about the possibili...
Latex anaphylaxis.
Ferreira, M B; Serviço de Medicina III, Hospital de Santa Maria, Faculdade de Medicina de Lisboa.; Pedro, E; Barbosa, M A; Carlos, A GThe authors present two case-reports of Latex Anaphylaxis--a rare but dangerous manifestation of latex allergy--, one in a patient belonging to a risk group and the other in a patient without previously identified risk factors. A review of latex allergy, and particularly of latex anaphylaxis, is made focusing on risk groups, aetiology, diagnosis, prevention and therapy. This paper also intends to draw attention...
