Effects of an evaporative cooling system on plasma cortisol, IGF-I, and milk pr...
Titto, C.G.; Negrão, J.A.; Titto, E.A.L.; Canaes, T.S.; Titto, R.M.; Pereira, A.M.F.Access to an evaporative cooling system can increase production in dairy cows because of improved thermal comfort. This study aimed to evaluate the impact of ambient temperature on thermoregulation, plasma cortisol, insulin-like growth factor 1 (IGF-I), and productive status, and to determine the efficiency of an evaporative cooling system on physiological responses under different weather patterns. A total of ...
Antioxidant capacity and toxicological evaluation of pterospartum tridentatum f...
Ferreira, Fernanda M.; Dinis, Lia T.; Azedo, Pedro; Galhano, Cristina; Cardoso, Susana M.; Domingues, M.R.M.; Pereira, Olívia R.; Simões, AnabelaPterospartum tridentatum Willk. (prickled broom) is an autochthonous plant, common in Portuguese territory. The yellow flowers are used in traditional medicine, as a potential cure for all body illnesses, mainly for throat irritation treatment or for diabetes, hypertension and hypercholesterolemia therapy.Despite its traditional use, no toxicological assessment has been performed as we know. A high antioxidant ...
Cinética de fermentação ruminal de silagens de milheto
Guimarães Jr.,R.; Gonçalves,L.C.; Maurício,R.M.; Pereira,L.G.R.; Tomich,T.R.; Pires,D.A.A.; Jayme,D.G.; Sousa,L.F.Avaliaram-se a degradabilidade da matéria seca e a cinética de fermentação ruminal das silagens de três genótipos de milheto (BRS-1501, NPM-1 e CMS-3), por meio da técnica in vitro semi-automática de produção de gases. O delineamento experimental utilizado foi o de blocos ao acaso em arranjo de parcelas subdivididas. Para a comparação dos genótipos, foi utilizado o teste SNK (P<0,05), e os parâmetros da cinétic...
Tronchuda cabbage (Brassica oleracea L. var. costata DC) seeds: phytochemical c...
Ferreres, F.; Sousa, C.; Valentão, P.; Seabra, R.M.; Pereira, J.A.; Andrade, P.B.Tronchuda cabbage (Brassica oleracea L. var. costata DC) seeds were studied for their chemical composition and antioxidant capacity. Thirteen phenolic compounds were characterized and quantified by reversed-phase HPLC-DAD-MS/MS-ESI and HPLC-DAD, respectively: two sinapoylgentiobiose isomers, three sinapoylglucose isomers, kaempferol-3-(sinapoyl)sophorotrioside-7-glucoside, sinapoylcholine, kaempferol-3,7-digluc...
Screening of antioxidant compounds during sprouting of Brassica oleracea L. var...
Sousa, C.; Lopes, Graciliana; Pereira, D.M.; Taveira, M.; Valentão, P.; Seabra, R.M.; Pereira, J.A.; Baptista, Paula; Ferreres, F.; Andrade, P.B.The changes in antioxidant compounds of Brassica oleracea L. var. costata DC seeds were monitored during the first twelve days of seedling development. Sprouts were screened at time intervals of two days for phenolic compounds and organic acids. The identified phenolic compounds included esters of sinapic acid with glucose, gentiobiose and kaempferol, as well as sinapoylcholine. The organic acids were oxalic, a...
Composição fenólica e actividade antimicrobiana em azeitonas descaroçadas “Alca...
Sousa, Anabela; Ferreira, Isabel C.F.R.; Estevinho, Leticia M.; Andrade, P.B.; Valentão, P.; Bento, Albino; Seabra, R.M.; Pereira, J.A.Em Trás-os-Montes, no início do Outono, são produzidas azeitonas descaroçadas em pedaços, conhecidas como “alcaparras”, muito apreciadas e consumidas na região principalmente nos períodos de Outono-Inverno. Com a realização do presente trabalho, pretendeu-se por um lado proceder à caracterização da fracção fenólica deste tipo de azeitona de mesa por HPLC/DAD, e por outro proceder à avaliação in vitro de extract...

Cortes, Helder Carola Espiguinha; J. Chagas e Silva; M.C. Baptista; R.M.Pereira; Leitão, A.; A.E.M.Horta; M.I.Vasques; J.P.Barbas; C:C:MarquesBesnoitia besnoiti impact on fertility of cattle exploited in Mediterranean pastures (Alentejo) Summary Besnoitia besnoiti is a bovine parasite endemic in many tropical and subtropical areas whose prevalence in the Mediterranean countries such as Portugal seems to be increasing. Most infections are mild or subclinical, characterized by the formation of numerous cutaneous and sub-cutaneous microcysts, lowering ...

Andrade, P.B.; Sousa, C.; Seabra, R.M.; Pereira, J.A.; Ferreres, F.Tronchuda cabbage (Brassica oleracca L. var. "oslalo DC) seeds were studied for their phenolic composition and antioxidant capacity. Thirteen compounds were characterized and quantified by reversed-phase HPLC-OAO-MSIMSESI and HPLC-OAD, respectively: two sinapoylgentiobiose isomers, three sinapoylglucosc isomers, kacmpferol-3- (sinapoyl)sophofOtrioside-7 -gI ucosidc, sinapoyIchol inc; kaempferol-3, 7-diglucoside...
Elastic, inelastic scatterings and transfer reactions for 16,18O on 58Ni descri...
Alves,J. J. S.; Gomes,P. R. S.; Lubian,J.; Chamon,L. C.; Anjos,R. M.; Pereira,D.; Rossi Jr.,E. S.; Silva,C. P.; Alvarez,M. A. G.; Nobre,G. P. A.We have used a parameter - free potential, obtained from data analysis at sub-barrier energies, to explain our measurements of elastic and several inelastic scattering cross sections for the 16,18O + 58Ni systems at an energy above the barrier. The data were analyzed through extensive coupled-channel calculations. Transfer cross sections could also be explained by the same interaction, which is consistent with ...
