Chitosan-collagen scaffolds can regulate the biological activities of adipose mesenchymal stem cells for tissue engineering

Scaffolds of chitosan and collagen can offer a biological niche for the growth of adipose derived stem cells (ADSC). The objective of this work was to characterize the physico-chemical properties of the scaffolds and the ADSC, as well as their interactions to direct influences of the scaffolds on the behavior of ADSC. The methodology included an enzymatic treatment of fat obtained by liposuction by collagenase, ASDC immunophenotyping, cell growth kinetics, biocompatibility studies of the scaffolds analyzed by the activity of alkaline phosphatase (AP), nitric oxide (NO) determination by the Griess-Saltzman reaction, and images of both optical and scanning electron microscopy of the matrices. The extent of the crosslinking of genipin and glutaraldehyde was evaluated by ninhydrin assays, solubility tests and degradation of the matrices. The results showed that the matrices are biocompatible, exhibit physical and chemical properties needed to house cells in vivo and are strong stimulators of signaling proteins (AP) and other molecules (NO) which are important in tissue healing. Therefore, the matrices provide a biological niche for ADSC adhesion, proliferation and cells activities.

Iniciativa privada e educação pública: contribuições metodológicas para a análise de objetos de pesquisa difusos na área de política e gestão educacional

Provides elements for a reflection on methodological strategies in the face of objects of study that prove difficult to approach. Through a case study in education, seeks to show that difficulties in obtaining information and data have been overcome by using an analytical model developed. It is shown that its use allowed inferences broader and reveal hidden inconsistencies in discussions on public and private education. Intended to assist reflection on qualitative research methods for those who deal with such studies. Concludes that the current expectations of management efficiency and transfer of resources sufficient quantity and quality have not materialized with a private enterprise under public education, even if we have succeeded in building a positive image by the promoters of this action with the sectors of public opinion. Prevailing trade policy interests at the expense of the motivations declared the initiative of aid to education, and even can not be said that the initiative has resulted in a private redefined the public character of the systems affected, there is evidence that its implementation represents a unique chapter focused "education", compared to a scenario in which stand out historically mutual aid agreements of a politicaleconomic development between state and private enterprise.

Ignacio de Assis Silva e os estudos literários

This paper aims to honor the semiotician Ignacio Assis Silva printed by the intensity in all his activities, emphasizing mainly on the accuracy insightful essays, which made him not only one of the most important promoters of semiotics greimasian in Brazil, but one of those responsible for its development. It should be noted also that he served with dedication in the Postgraduate Program in Literary Studies FCL/Araraquara UNESP, including efforts since its founding. The program owes much to him and others of FCL semioticians for the healthy integration between programs, Linguistics/Portuguese Language and Literary Studies. The latter was even initially, a literature program focusing on semiotics greimasian. Join together with all his persistent interest in building a "theory of language", which deeply and tenaciously pursued in their classes and in their texts and can be detected in Figurativização e metamorfose: o mito de Narciso (1995).

Cooperative effects of H+ and H- hydrido carbonyl ruthenium derivatives; role of homogeneous and heterogeneous protonic and lewis acids in catalytic hydrocarbonylation reactions

The role played by H+ hydrido iodocarbonyl and H- hydrido carbonyl ruthenium catalysts in the different catalytic steps of hydroformylation and hydroesterification of olefins, and in the homologation of alcohols has been investigated. The H- hydrido carbonyl species are mainly involved in the activation of olefins and in the hydrogenation of the acyl intermediates to aldehydes and alcohols, whereas the H+ hydrido iodocarbonyl derivatives are involved in the activation of alcohols and other oxygenated substrates, and in their carbonylation to esters. The cooperation between the two species, possible under particular reaction conditions, results in an improvement of the selectivity towards homologation (carbonylation plus hydrogenation) products. Heterogeneous Lewis acid promoters, easily recyclable from the reaction mixture, have also been successfully used in the hydrocarbonylation of alcohols, resulting in an increase of the carbonylation and homologation products. A reaction pathway in agreement with the experimental results is discussed. © 1989.

Current outlook and future perspectives of beef production in Brazil

Brazil is the world's largest beef exporter with the world's largest commercial cattle herd; however, the production cycle needs to be more efficient to supply internal and external demands in the future. Feedlot operations are currently a reality for the Brazilian beef cattle industry; nonetheless the beef cattle industry in Brazil is still based on grass-fed animals in which the Nellore breed predominates. At some point this constitutes an important advantage for Brazilian beef exportations because some countries look for “natural beef.” Brazilian packing plants regulate the use of antibiotics, especially ionophores used as growth promoters, on farms certified to export beef to European countries. In addition, the use of any implant or beta-agonist for cattle is forbidden in Brazil. From 1970 to 2006, the Brazilian bovine herd increased at 2.04%/year, total pasture at 0.07%/year, area with cultivated pasture at 3.5%/year, and ratio of animals/hectare of total pasture at 1.97%/year, whereas the area with natural pasture decreased at 2.26%/year. These trends alleviate some of the pressure on Brazilian authorities with respect to deforestation of the Amazon forest. Although Brazil had the greatest growth rate of enteric methane emissions, it also had the greatest growth rate of beef production, resulting in Brazil having a negative growth rate (–1.82%/year) of methane emissions per unit of product (kilogram of methane/kilogram of beef).
