Bile And Liver Metallothionein Behavior In Copper-exposed Fish.

The present study analyzed metallothionein (MT) excretion from liver to bile in Nile Tilapia (Oreochromis niloticus) exposed to sub-lethal copper concentrations (2mgL(-1)) in a laboratory setting. MTs in liver and bile were quantified by spectrophotometry after thermal incubation and MT metal-binding profiles were characterized by size exclusion high performance liquid chromatography coupled to ICP-MS (SEC-HPLC-ICP-MS). Results show that liver MT is present in approximately 250-fold higher concentrations than bile MT in non-exposed fish. Differences between the MT profiles from the control and exposed group were observed for both matrices, indicating differential metal-binding behavior when comparing liver and bile MT. This is novel data regarding intra-organ MT comparisons, since differences between organs are usually present only with regard to quantification, not metal-binding behavior. Bile MT showed statistically significant differences between the control and exposed group, while the same did not occur with liver MT. This indicates that MTs synthesized in the liver accumulate more slowly than MTs excreted from liver to bile, since the same fish presented significantly higher MT levels in liver when compared to bile. We postulate that bile, although excreted in the intestine and partially reabsorbed by the same returning to the liver, may also release MT-bound metals more rapidly and efficiently, which may indicate an efficient detoxification route. Thus, we propose that the analysis of bile MTs to observe recent metal exposure may be more adequate than the analysis of liver MTs, since organism responses to metals are more quickly observed in bile, although further studies are necessary.

As medidas de confiança no Conselho de Defesa Sul-americano (CDS): análise dos gastos em Defesa (2009-2012)

Analisamos a metodologia de aferição de gastos em Defesa do Conselho de Defesa Sul-americano (CDS). Discutimos fundamentos, inovações, limitações e perfil de gastos. Na região, a folha de pagamento de pessoal e encargos previdenciários consumiram 60% do total dos gastos em Defesa entre 2006 e 2010, enquanto as pesquisas em tecnologia apenas 0,5%. Sobre esse diagnóstico, defendemos a modernização das FA e os Ministérios da Defesa da região, sobretudo uma racional e equalizada distribuição dos gastos por objeto, antes de aumentar as verbas para o setor.

Tissue distribution of residual antimony in rats treated with multiple doses of meglumine antimoniate

Meglumine antimoniate (MA) and sodium stibogluconate are pentavalent antimony (SbV) drugs used since the mid-1940s. Notwithstanding the fact that they are first-choice drugs for the treatment of leishmaniases, there are gaps in our knowledge of their toxicological profile, mode of action and kinetics. Little is known about the distribution of antimony in tissues after SbV administration. In this study, we evaluated the Sb content of tissues from male rats 24 h and three weeks after a 21-day course of treatment with MA (300 mg SbV/kg body wt/d, subcutaneous). Sb concentrations in the blood and organs were determined by inductively coupled plasma-mass spectrometry. In rats, as with in humans, the Sb blood levels after MA dosing can be described by a two-compartment model with a fast (t1/2 = 0.6 h) and a slow (t1/2 >> 24 h) elimination phase. The spleen was the organ that accumulated the highest amount of Sb, while bone and thyroid ranked second in descending order of tissues according to Sb levels (spleen >> bone, thyroid, kidneys > liver, epididymis, lungs, adrenals > prostate > thymus, pancreas, heart, small intestines > skeletal muscle, testes, stomach > brain). The pathophysiological consequences of Sb accumulation in the thyroid and Sb speciation in the liver, thyroid, spleen and bone warrant further studies.

Biblia [Vetus et Novum Testamentum].

La Bible s’ouvre par deux compositions poétiques d’Alcuin qui encadrent l’Épître de saint Jérôme à Paulinus, « Frater Ambrosius... » (ff. 1-2r : Monumenta Germaniae Historica, Poetae latinae, I, 1, p. 287, LXVIII-LXX, v. 1-200 ; ff. 4r-v : Monumenta Germaniae Historica, Poetae latinae, I, 1, p. 283-284, LXV, I-III). La fin manque: la Bible s'interrompt à la fin de l'Epître de saint Paul aux Colossiens.
