Immunomodulatory activities associated with β-glucan derived from Saccharomyces cerevisiae

In this study we investigated the effect of β-glucan derived from Saccharomyces cerevisiae on fungicidal activity, cytokine production and natural killer activity. Spleen and peritoneal cells from female C57BL/6 mice, previously injected (24 or 48 h) with 20 or 100 μg of glucan by i.p. route, were assayed. In vivo β-glucan administration primed spleen cells for a higher production of IL-12 and TNF-α when S. aureus was used as a stimulus. In addition, β-glucan increased NK spleen cells activity against YAC target cells. Some immunomodulatory activities not yet described for β-glucan were observed in this work. © 2005 Institute of Physiology, Academy of Sciences of the Czech Republic.

Additional observations on the gross morphology and microstructure of Baccaconularia Hughes, Gunderson et Weedon, 2000, a Cambrian (Furongian) conulariid from the north-central USA

Baccaconularia Hughes, Gunderson et Weedon, 2000, from the Furongian Series (Cambrian System) of the north-central USA, has been interpreted as a conulariid cnidarian, based on a suite of gross morphological similarities shared only with other post-Cambrian genera currently assigned to this group. Closely spaced, squarish to subrectangular facial nodes of Baccaconularia are aligned in distinct longitudinal files. Nodes also display a subtler, more or less rectilinear transverse alignment, though this pattern commonly is disrupted by offset parallel to the longitudinal files. In their shape and pattern of arrangement, the nodes of Baccaconularia are most similar to the squarish to elongate nodes of Pseudoconularia Bouček, 1939. Longitudinal node files of Baccaconularia may also be compared with the longitudinal facial ridges of Conularia cambria Walcott, 1890 from the Furongian of Wisconsin. Apical angles of Baccaconularia range from approximately 13° to 14.5°. Scanning electron imaging of B. cf. robinsoni shows that its thin, phosphatic skeleton is finely lamellar, with the thickness of individual lamellae measuring approximately 1 μm. The skeleton also exhibits microscopic circular pores and crater-like pits that range from approximately 5 to 10 μm in diameter. These pores and pits are similar in size, geometry, areal density and pattern of arrangement to those of many post-Cambrian conulariids. Microscopic circular pores are documented here for the first time in the genus Archaeoconularia Bouček, 1939 from the Upper Ordovician of the Czech Republic. Although the origin of the pores and pits is open to alternative interpretations, the discovery of these features and fine lamination in Baccaconularia strengthens the argument that this genus is a Cambrian conulariid. © 2006 Nanjing Institute of Geology and Palaeontology, CAS.

Investigando a legitimidade: Estudo de atitudes de público em relação aos papéis do Estado e do mercado

Using data collected in nine countries - Argentina, Brazil, Chile, Czech Republic, Poland, Russian Federation, Finland, Germany and the USA - through the World Values Survey, the article analyses the validity of four variables with a supposed potential to evaluate the legitimacy level of the private sector vis-à-vis the public sector. This analysis in undertaken in the context of the discussions on the future of market reforms that were implemented in several countries in the past 20 years. The investigation adopted a two level strategy: first, the aggregated frequencies for the nine countries were analyzed, followed by a bivariate analysis aimed at verifying the internal consistency of the variables. The article concludes that the four variables under consideration do not compose a valid dimension capable of assessing the legitimacy of the public sector versus the private sector.

Heat transfer in a packed sugar cane bagasse bed

Heat transfer in a packed bed of sugar cane bagasse, which is a potential biofuel used in cars and industries, percolated with air flow was studied. The fibers were washed, sieved, oven dried, and afterwards moisture content was adjusted to 4 and 47%. The relative humidity of the air, packing bed technique, and the initial moisture content of the porous media did not have a significant effect on the outlet temperature of the bed. Air flow rate influenced the averaged radial temperature profile, but not the temperature measured at the nearest position to the tube wall. At the end of the experiments, moisture segregation was observed, the lower bed depths being drier than the higher ones. This is an abstract of a paper presented at the 18th International Congress of Chemical Process Engineering (Praque, Czech Republic 8/24-28/2008).

Migração Kirchhoff pré-empilhamento em profundidade modificada usando o operador de feixes gaussianos

A teoria dos feixes gaussianos foi introduzida na literatura sísmica no início dos anos 80 por pesquisadores russos e tchecos, e foi originalmente utilizada no cálculo do campo de ondas eletromagnéticas, baseado na teoria escalar da difração. Na teoria dos feixes gaussianos, o campo de ondas sísmicas é obtido por uma integral, cujo o integrando é constituído de duas partes, a saber: (1) as amplitudes dos campos das ondas na vizinhança do ponto de observação e (2) a função fase de cada um desses campos de ondas, que neste caso é representada por um tempo de trânsito paraxial complexo. Como ferramenta de imageamento, mais precisamente como operador de migração, os primeiros trabalhos usando feixes gaussianos datam do final da década de 80 e início dos anos 90. A regularidade dos campos de ondas descritos pelos feixes gaussianos, além de sua alta precisão em regiões singulares do modelo de velocidades, tornaram o uso de feixes gaussianos como uma alternativa híbrida viável para a migração. Nesse trabalho, unimos a flexibilidade da migração tipo Kirchhoff em profundidade em verdadeira amplitude com a regularidade da descrição do campo de ondas, representado pela sobreposição de feixes gaussianos. Como forma de controlar de forma estável quantidades usadas na construção de feixes gaussianos, utilizamos informações advindas do volume de Fresnel, mais precisamente a zona de Fresnel ao redor do ponto de reflexão e a zona de Fresnel projetada, localizada ao redor do ponto de registro do sismograma e cuja a informação se encontra nas curvas de reflexão de dados sísmico. Nosso processo de migração pode ser chamado como uma migração Kirchhoff em verdadeira amplitude usando um operador de feixes gaussianos.

Cyclodextrin Production by Bacillus lehensis Isolated from Cassava Starch: Characterisation of a Novel Enzyme

The properties of a previously unknown enzyme, denominated cyclodextrin glycosyltransferase, produced from Bacillus lehensis, were evaluated using affinity chromatography for protein purification. Enzyme characteristics (optimum pH and temperature; pH and temperature stability), the influence of substances on the enzyme activity, enzyme kinetics, and cyclodextrin production were analysed. Cyclodextrin glycosyltransferase was purified up to 320.74-fold by affinity chromatography using beta-cyclodextrin as the binder and it exhibited 8.71% activity recovery. This enzyme is a monomer with a molecular weight of 81.27 kDa, as estimated by SDS-PAGE. Optimum temperature and pH for cydodextrin glycosyltransferase were 55 degrees C and 8.0, respectively. The Michaelis-Menten constant was 8.62 g/l during maximum velocity of 0.858 g/l.h.

Health related quality of life measure in systemic pediatric rheumatic diseases and its translation to different languages: an international collaboration

Background: Rheumatic diseases in children are associated with significant morbidity and poor health-related quality of life (HRQOL). There is no health-related quality of life (HRQOL) scale available specifically for children with less common rheumatic diseases. These diseases share several features with systemic lupus erythematosus (SLE) such as their chronic episodic nature, multi-systemic involvement, and the need for immunosuppressive medications. HRQOL scale developed for pediatric SLE will likely be applicable to children with systemic inflammatory diseases.Findings: We adapted Simple Measure of Impact of Lupus Erythematosus in Youngsters (SMILEY (c)) to Simple Measure of Impact of Illness in Youngsters (SMILY (c)-Illness) and had it reviewed by pediatric rheumatologists for its appropriateness and cultural suitability. We tested SMILY (c)-Illness in patients with inflammatory rheumatic diseases and then translated it into 28 languages. Nineteen children (79% female, n= 15) and 17 parents participated. The mean age was 12 +/- 4 years, with median disease duration of 21 months (1-172 months). We translated SMILY (c)-Illness into the following 28 languages: Danish, Dutch, French (France), English (UK), German (Germany), German (Austria), German (Switzerland), Hebrew, Italian, Portuguese (Brazil), Slovene, Spanish (USA and Puerto Rico), Spanish (Spain), Spanish (Argentina), Spanish (Mexico), Spanish (Venezuela), Turkish, Afrikaans, Arabic (Saudi Arabia), Arabic (Egypt), Czech, Greek, Hindi, Hungarian, Japanese, Romanian, Serbian and Xhosa.Conclusion: SMILY (c)-Illness is a brief, easy to administer and score HRQOL scale for children with systemic rheumatic diseases. It is suitable for use across different age groups and literacy levels. SMILY (c)-Illness with its available translations may be used as useful adjuncts to clinical practice and research.
