No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Nutrição, Florianópolis, 2010O melado é um alimento natural, doce e de boa aceitação pelos consumidores, mas ainda pouco estudado. Este trabalho teve como objetivo analisar as características nutricionais de melados produzidos em Santa Catarina. Para isso, foram observadas algumas características da produção, foi feita a composição centesimal, a determinação do teor de ferro, cálcio, cobre, polifenóis totais e capacidade antioxidante. Além disso, foi realizada uma entrevista sobre o conhecimento e o consumo de melado em uma amostra populacional. Foram analisadas 13 amostras de melados catarinenses, as quais são produzidas em tachos de ferro, cobre ou aço inoxidável. As amostras apresentaram em média 75,51g% de carboidratos, 0,94g% de proteínas, menos de 0,2g% de lipídeos, 0,7g% de cinzas, 19,72g% de umidade, 24,02mg% de cálcio e 1,34mg% de cobre. Foi verificado um valor médio de 0,54mg% de ferro no caldo da cana. Em 13 amostras de melado, foram encontrados em média, 3,30mg% de ferro e 2,958mg GAE/g de polifenóis totais. Quanto à capacidade antioxidante, os melados tiveram a média de EC50 = 0,00014g /g DPPH. Foi verificado que os melados de Santa Catarina contêm ferro em quantidades variáveis, que a cana também apresenta ferro na sua composição e o material dos utensílios parece não influenciar o teor de ferro dos produtos. Foi observado também um alto conteúdo de polifenóis e uma alta capacidade antioxidante. A aplicação do questionário mostrou que o melado é consumido de diversas formas por mais da metade dos entrevistados e destes, 36% fez menção ao melado ser rico em ferro ou indicado para combater a anemia ferropriva. São necessários mais estudos com melados de diferentes locais, investigando seu teor e biodisponibilidade de ferro, conteúdo de polifenóis e efeitos de sua atividade antioxidante.Sugar cane syrup is a natural food, sweet and well received by consumers, but still little studied. The aim of this study was to analyze the nutritional characteristics of sugar cane syrup produced in Santa Catarina. For this, some aspects of the production were observed, nutricional composition was determined and iron, calcium, copper, total polyphenols and antioxidant capacity were determined. In addition, an interview was conducted on the awareness and consumption of sugar cane syrup in a population sample. Thirteen samples of sugar cane syrups from Santa Catarina were analyzed, which are produced in pots of iron, copper or stainless steel. The samples had an average of 75,51g% carbohydrate, 0,94g% protein, less than 0,2g% lipids, 0,7g% ash, 19,72g% moisture, 24,02mg% calcium and 1,34mg% copper. It was observed an average of 0,54mg% of iron in the cane juice. In 13 samples of sugar cane syrup, were found on average 3.30mg% iron and 2.958mg GAE/g of total polyphenols. The antioxidant capacity, the sugar cane syrup had a mean EC50= 0.00014g/g DPPH. It was found that the sugar cane syrup from Santa Catarina contain iron in varying quantities, the cane also has iron in its composition and material of the utensils does not influence the iron content of the products. It was also observed a high content of polyphenols and a high antioxidant capacity. The application of the questionnaire showed that the sugar cane syrup is consumed in various forms for more than half of respondents and of these, 36% mentioned the sugar cane syrup as rich in iron or effective to combat anemia. Further studies are needed with sugar cane syrup from different locations, investigating its iron content and bioavailability, polyphenol content and effects of its antioxidant activity

Method development for flow-cytometric analysis of primary human airway epithelia infected with non-typeable Haemophilus influenzae
No full textIntroduction: non-typeable Haemophilus influenzae (NTHi) is a pathobiont which persists in the airways of patients with chronic obstructive pulmonary disease, cystic fibrosis and primary ciliary dyskinesia (PCD). NTHi airway colonisation is associated with chronic inflammation leading to bronchiectasis and disease exacerbation. It is not known if NTHi invades a specific subset of airway epithelial cells or if this differs by respiratory disease type.Aim: develop a flow-cytometric method to identify major subsets of airway epithelial cells infected with NTHi.Methods: primary human nasal (n=3) and bronchial (n=4) epithelial cells were air-liquid interface cultured for 4 weeks. Cultures were infected with a fluorescein-labelled NTHi PCD clinical isolate for 1-h and then treated with gentamicin (200 µg/mL for 1-h) to remove surface-attached bacteria. Fluorescein-labelled antibodies were used to identify cellular subsets by flow cytometry: Tubulin Tracker™ (ciliated), CD49f (basal), CD66c (secretory). Infected samples were compared to uninfected to confirm NTHi internalisation.Results: secretory cells were the most abundant subset followed by ciliated then basal. Internalised NTHi (mean % infected per subtype) were detected within bronchial secretory (0.3%), ciliated (0.2%) and basal (0.2%) and nasal secretory (3.5%), ciliated (2.3%) and basal (2.7%), suggesting infection rate is higher in the upper airway compared to lower.Conclusions: flow cytometry is a sensitive tool for detecting and quantifying NTHi internalisation in cultured airway epithelial cell subsets. This method could provide a readout analysing the therapeutic effects of drug treatments

Preliminary estudies on the use of sugar cane bagasse ash (SCBA) in the manufacture of alkali activated binders
No full textAlkali activated binders require the addition of a mineral-rich amorphous silica and alumina. This paper proposes the use of a mineral residue from the burning of sugar cane bagasse. The alkali activated mixtures were prepared containing binary mixtures of sugar cane bagasse ash (SCBA) and other mineral admixtures: fly ash (FA) or blast furnace slag (BFS). As alkaline activators, mixtures of alkali (Na+ or K+) hydroxide and alkali (Na+ or K+) silicate were used. Alkali-activated pastes and mortars containing binary systems SCBA/FA or SCBA/BFS were prepared and cured at 65 oC. Microstructural properties of these alternative binders were assessed by means of TGA, SEM, XRD and pH measurements. Mechanical strength of mortars was performed after 3 and 7 days at 65 oC. Compressive mechanical strengths of these mortars were in the range 30-55 MPa, showing the good mechanical performance achieved by the alkali activation. Microstructural studies suggested the development of stable matrices and the formation of typical gel.Castaldelli, V.; Mitsuuchi Tashima, M.; Melges, J.; Akasaki, JL.; Monzó Balbuena, JM.; Borrachero Rosado, MV.; Soriano Martínez, L....

Excoriose, Cane Blight and Related Diseases of Grapevines : A Taxonomic Review of the Pathogens
No full textThe disease of grapevines known as excoriose has been the source of a certain amount of controversy.
Much of this concerns the identity of the causal agent and this has been further confounded by the taxonomic problems
of the fungal pathogens associated with this disease. Many of these problems have now been resolved and it is
clear that excoriose is caused by Botryosphaeria dothidea while cane blight and leaf spot is caused by Phomopsis
viticola. However, although at least five different species of Phomopsis are currently known to be associated with
grapevines, only P. viticola causes cane blight and leaf spot. The role played by the other species of fungi is not clear,
but they may be weak pathogens, saprophytes or endophytes
Feasibility Study of a Balanced Upper Arm Orthosis based on Bending Beams
No full textPeople with neuromuscular diseases request an orthosis close to the body for assistance with their arm movements. This paper proposes a concept for a passive arm support that is close to the body and is based on bending beams. Simulations resulted in the final configuration and dimensions of the beams, optimised to balance an arm. One Carbon-fibre-reinforced polymer beam with dimensions 0.22x0.0041x0.0027m at the medial side and one at the lateral side of the upper arm delivers the required energy for balancing the arm. Experimental evaluation of a prototype demonstrated the technical principle; more than 87% of the moment around the shoulder was balanced between 0 and 1.1rad. A second prototype was built for preliminary evaluation of the concept in relation to the body. The width of the elastic and structural elements was more than four times smaller than in present arm supports. From this it was concluded that bending beams have the potential to make an orthosis that is closer to the upper arm than current orthoses.BMEBioMechanical EngineeringMechanical, Maritime and Materials Engineerin

J.L. Brierly and The Modernization of International Law
No full textIn this Article, the author provides an analysis of a classic of international law, The Law of Nations, by J.L. Brierly. The author describes Brierly as an international legal scholar whose modernization of international law involves an emphasis on fact and complexity, an emphasis that is ultimately little more than a gesture. The author then examines the narrative structure of The Law of Nations and indicates the normative messages disclosed in Brierly\u27s telling of the story of international law. Finally, the author describes Brierly\u27s effort to describe international law as occupying a political realm while Brierly\u27s evolutionary optimism made him anything but a political realist. In short, the author sees in Brierly\u27s promises of complexity and realism a thinly veiled simplicity that would be subsumed into the orthodoxies of international legal thought
