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 ...
Pasture digital image analysis as a support tool for grazing management in mont...
Rato, Luis; Ferraz de Oliveira, M Isabel; Sales-Batista, ElviraThe knowledge of vegetation land cover over time is essential for an appropriate grazing management in any free range animal production system. Ground vegetation has traditionally been monitored using visual methods that produce estimates of percentage covered/bared soil, green/senescent vegetation and also grasses/forbs occurrences. Visual methods are extremely time consuming and prone to observer bias. The us...
Implications of infectious diseases and the adrenal hypothesis for the etiology...
Azevedo-Silva,F.; Camargo,B.de; Pombo-de-Oliveira,M.S.Acute leukemia is the most frequent cancer in children. Recently, a new hypothesis was proposed for the pathogenesis of childhood acute lymphoblastic leukemia (ALL). The so-called "adrenal hypothesis" emphasized the role of endogenous cortisol in the etiology of B-cell precursor ALL. The incidence peak of ALL in children between 3 to 5 years of age has been well documented and is consistent with this view. The ...
Comparative vibrational spectra of pilosine and epiisopilosine crystals
Bento,R.R.F.; Silva,L.E. da; Faria,J.L.B.; Freire,P.T.C.; de Oliveira,M.C.F.; Romero,N.R.; Teixeira,A.M.R.; Pontes,F.M.This paper describes the study of two alkaloids extracted from Pilocarpus Microphyllus (Rutaceae): pilosine and epiisopilosine. These substances have potential application in the treatment of several diseases. In this work FT-Raman and the FT-IR spectra of pilosine and epiisopilosine were investigated at 300 K. Vibrational wavenumber and wave vector have been predicted using density functional theory (B3LYP) ca...
Chemical composition and larvicidal activity of Rollinia leptopetala (Annonaceae)
Feitosa,Edinilza M. A.; Arriaga,Ângela M. C.; Santiago,Gilvandete M. P.; Lemos,Telma L. G. de; Oliveira,M. Conceição F. de; Vasconcelos,Jackson Nunes eThe aim of present study was to describe the chemical composition of the essential oils from the leaf and stem of Rollinia leptopetala R. E. Fries (Annonaceae) and to evaluate the larvicidal activities of these essential oils, of the methanol extract from roots of this plant and of the oxoaporphine alkaloid, liriodenine (1) against the third-instar of Aedes aegypti larvae. The methanol extract from the roots sh...
