O texto apresenta, no que concerne ao fenômeno imigratório, o enigma da invisibilidade relativa na sociedade brasileira do grande número de espanhóis, concentrados no Estado de São Paulo durante, sobretudo, a Primeira República A análise restringe-se às obras da literatura brasileira que assinalaram a presença de personagens espanholas.

OBJETIVO: Avaliar o efeito do resveratrol sobre a via de sinalização da insulina e melhora do quadro inflamatório no miocárdio de ratos Wistar obesos induzidos por dieta.MÉTODOS: Ratos Wistar foram divididos em grupos: controle (dieta padrão para roedores), obeso (dieta hiperlipídica) e obeso suplementado com resveratrol (20 mg/kg/dia), por 8 semanas (n=10). Ao final do período experimental, realizou-se o teste de tolerância à insulina, nos tempos 0 (sem insulina), 5, 10, 15, 20, 25 e 30 minutos após injeção intraperitoneal de insulina (2 U/kg). O peso corporal e o tecido adiposo epididimal foram mensurados. Fragmentos do miocárdio foram extraídos para análises da via da insulina e moléculas pró-inflamatórias através de Western blot.RESULTADOS: Os resultados indicam que a intervenção com resveratrol aumenta a constante de decaimento da glicose, fosforilação do receptor de insulina, substrato do receptor de insulina e da proteína quinase B. A suplementação de resveratrol também reduziu os níveis proteicos do fator de necrose tumoral alfa e de moléculas envolvidas com a transdução do sinal pró-inflamatório (quinase indutora do kappa B e fator nuclear kappa B). Os resultados ainda sugerem que a melhora na sensibilidade à insulina e a redução das moléculas pró-inflamatórias ocorreram independentemente da perda de peso corporal e da redução do tecido adiposo epididimal.CONCLUSÃO: A suplementação de resveratrol aumenta a sensibilidade à insulina, o que está relacionado à redução de fatores inflamatórios no miocárdio.

Among alternatives to replace ionophores, which are classified as antibiotics by some committees, the feeding of polyclonal antibodies have shown an interesting and economically efficient alternative. Recent studies have demonstrated some advantages of adding polyclonal antibodies into high-concentrate diets for feedlot cattle, showed by increased performance and ruminal health, in some cases similar to sodium monensin. However, there are blind spots of this innovated technology that still need to be elucidated, as example, if the dry form of the preparation is inactivated and decreased carcass-dressing percentage. All in all, this review demonstrates the possibility of replacing sodium monensin by this feed additive without negatively impacting animal performance and profit of cattle feeders in Brazil.

The aim of this work was to evaluate the performance and the liver structure health of Nile tilapia hormonally masculinized or nonmasculinized, reared in cages with two protein levels. Two groups of Nile tilapia of Thai lineage (total 2,400), with 127 g initial average weight, were distributed in a completely randomized design with four treatments, in a 2x2 factorial arrangement, corresponding to the groups of hormonally masculinized or nonmasculinized fish, and to diet protein level of 28 or 32% of crude protein, with three replicates. After 115 days feeding, there was no interaction between the factors for final weight, weight gain, feed conversion rate, final length and survival. There was no difference between hormonally masculinized and nonmasculinized fish for final weight, weight gain, and survival, which shows the possibility of their production in cages, without the need of hormonal masculinization. Crude protein at 32% in the diet enables a better performance for both groups. Histological changes in the liver - such as increased cell volume, disruption of the cord-like arrangements, and increase of vesicles in the hepatocytes - are found in hormonally masculinized fish, and are more pronounced in fish fed 32% crude protein in the diet.

The goal of this study was to analyze international scientific production in the area of constant-production green supply chain management from 2001 to 2012 using the Business Source Complete database (EBSCO Host). The database was checked for cooperation between authors and institutions, author entrants, production and continuity categories, regularity of publication and distribution of publications over time. Ninety articles were included in the sample, and the results showed a reduction in the number of publishing authors, concentrated in one-timers category with 68.90%. The highest yield for a single author was 10 articles, and the most prolific periodical was the Journal of Cleaner Production, with 12 articles published on the subject. Clark University (USA) stood out in terms of output, with 12 affiliated authors. It was concluded that the subject had experienced a significant rise in published literature over that time period.
