Pitfalls in the assessment of murine atherosclerosis

This review provides examples of the fact that different procedures for the measurement of atherosclerosis in mice may lead to interpretation of the extent of atherosclerosis having markedly different biological and clinical significance for humans: 1) aortic cholesterol measurement is highly sensitive for the detection of early and advanced atherosclerosis lesions, but misses the identification of the location...

Lability of Cd, Cr, Cu, Mn and Pb complexed by aquatic humic substances

The lability of Cd(II), Cr(III), Cu(II), Mn(II) and Pb(II) complexed by humic substances (HSs) was investigated by means of ion exchange on cellulose modified with p-aminobenzoic groups (Cell-PAB), using a batch procedure. The HSs were extracted from water samples using adsorption in a column packed with XAD 8 resin. The metal-HS complexes were prepared by adding solutions containing all the aforementioned meta...

Genetic parameters estimates for gestation length in beef cattle

Variance components were estimated for gestation length fitting the additive direct effect of calf, maternal genetic effect and sire effect as random effects. The statistical models also included the fixed effects of contemporary group, that included the date of breeding (AI), date of birth, and sex of calf, and the covariate age of dam at calving (linear and quadratic). Two different models were used, model 1 ...

Estudo preliminar da atividade antiinflamatória de Bryophillum calycinum Salisb

Foram avaliados a toxicidade aguda (DL50) do Extrato Bruto Aquoso Liofilizado das folhas de Bryophillum calycinum Salisb. (EBALBc) e seu efeito antiinflamatório sobre o edema de pata de rato induzido por carragenina e dextrana. Com a dose de 500 mg/kg (p.o) inibiu o edema de pata induzido por dextrana de maneira significativa (p < 0.05, ANOVA, Teste de Student Newman-Keuls) nos tempos de 60 e 90 minutos, enquan...

Determination of Copper, Iron, Nickel and Zinc in fuel kerosene by FAAS after a...

Silica gel chemically modified with 2-Aminotiazole groups, abbreviated as SiAT, was used for preconcentration of copper, zinc, nickel and iron from kerosene, normally used as a engine fuel for airplanes. Surface characteristics and surface area of the silica gel were obtained before and after chemical modification using FT-IR, Kjeldhal and surface area analysis (B.E.T.). The retention and recovery of the analyt...

Foram obtidas estimativas de parâmetros genéticos e preditas DEP’s (diferença esperada na progênie) para pesos não-padronizados aos 120 dias de idade (PR120), à desmama (PR240), ao ano de idade (PR365), aos 15 meses (PR455) e ao sobreano (PR550), de 29.769 animais Nelore, adotando-se o método REML, sob modelo animal. Para características PR120, PR240, PR365 e PR455, o modelo completo incluiu efeitos aleatórios ...
