Susceptibility profile of a Brazilian yeast stock collection of Candida species isolated from subjects with Candida-associated denture stomatitis with or without diabetes

Objective: This study investigated the susceptibility of 198 clinical isolates of Candida species against caspofungin, amphotericin B, itraconazole, and fluconazole. Study Design: Suspensions of the microorganisms were spread on Roswell Park Memorial Institute (RPMI) agar plates. Etest strips were placed on the plates, and the minimal inhibitory concentration (MIC) was read after incubation (48 h at 37°C). Data were analyzed by a factorial analysis of variance and a 2 × 2 post hoc test (α = .05). Results: C glabrata showed the highest MIC values (P < .001) against caspofungin, itraconazole, and fluconazole. For amphotericin B, the MIC values of C tropicalis and C glabrata (P = .0521) were higher than those of C albicans (P < .001). Itraconazole was the least effective antifungal; 93.3% of the C glabrata isolates, 3.3% of the C albicans, and 1.3% of the C tropicalis were resistant. All microorganisms were susceptible to caspofungin and amphotericin B. Conclusions: Caspofungin and amphotericin B should be recommended as an effective alternative for the management of oral Candida infections when treatment with topical or other systemic drugs has definitely failed. © 2013 Elsevier Inc.

Caracterização Petrográfica e Tecnológica de Granitos Ornamentais do Stock Granítico Serra do Barriga, Sobral/CE

São apresentados resultados de análises petrográficas e do comportamento tecnológico de quatro variedades de granitos ornamentais do stock Serra do Barriga, localizado a NNW do estado do Ceará. Os tipos investigados são comercialmente conhecidos por Rosa Iracema, Rosa Olinda, Branco Savana e Branco Cristal Quartzo e correspondem a variedades de sienogranitos e monzogranitos, isotrópicos, inequigranulares de granulação média a grossa, com coloração que variam entre rosa e branco. Os resultados dos ensaios tecnológicos, com parâmetros físico-mecânicos bastante similares entre as quatro rochas, situam os granitos analisados como detentores de boas propriedades tecnológicas, indicados para utilização como pisos, bancadas, revestimentos de fachadas horizontais e verticais em ambientes de interiores e de exteriores. Correlações entre os resultados físico-mecânicos e características petrográficas das rochas mostram a influência dos aspectos mineralógicos, texturais e estruturais no comportamento de determinadas propriedades tecnológicas exibidas pelos referidos granitos ornamentais. Dentre os parâmetros petrográficos de maior influência verificados destacam-se a granulação grossa das rochas, teores de quartzo, grau de microfissuramento e alterações minerais, os quais controlam, em maior ou menor proporção, a porosidade aparente e consequente absorção d’água, resistência mecânica (compressão uniaxial; esforços flexores; impacto), desgaste abrasivo Amsler, dilatação térmica e propagação de ondas ultrassônicas exibidas pelos granitos.

Information Search Behavior: Proposal of Study with Investors in the Stock Market

With the aim of analyzing the information search behavior of investors working in the stock market, this research sought to raise the aspects related to this behavior with focus on the cognitive and causal aspects which pervade the need for information of these investors. For that, the general pattern of informational behavior proposed by Wilson [10], and also the analysis of a report from an investor of the stock market area were used as basis for the analysis and reflection. The report of only one investor was used as basis for investigation, turning it impossible to extrapolate such result to a greater universe. The objective of this research was to investigate the need for information, the context and the intervenient variables which might interfere or not in the information search behavior of investors, in an attempt to get a deeper comprehension about the subject, as well as to propose the continuity of studies with basis on this study proposal.

Information access law and disclosing of information by joint-stock companies in Brazil: open data and Extensible Business Reporting Language (XBRL) standard

The strategic management of information plays a fundamental role in the organizational management process since the decision-making process depend on the need for survival in a highly competitive market. Companies are constantly concerned about information transparency and good practices of corporate governance (CG) which, in turn, directs relations between the controlling power of the company and investors. In this context, this article presents the relationship between the disclosing of information of joint-stock companies by means of using XBRL, the open data model adopted by the Brazilian government, a model that boosted the publication of Information Access Law (Lei de Acesso à Informação), nº 12,527 of 18 November 2011. Information access should be permeated by a mediation policy in order to subsidize the knowledge construction and decision-making of investors. The XBRL is the main model for the publishing of financial information. The use of XBRL by means of new semantic standard created for Linked Data, strengthens the information dissemination, as well as creates analysis mechanisms and cross-referencing of data with different open databases available on the Internet, providing added value to the data/information accessed by civil society.

Estudo e análise estatística no mercado de ações brasileiro

The objective of this paper is to verify and analyze the existence in Brazil of stylized facts observed in financial time series: volatility clustering, probability distributions with fat tails, the presence of long run memory in absolute return time series, absence of linear return autocorrelation, gain/loss asymmetry, aggregative gaussianity, slow absolute return autocorrelation decay, trading volume/volatility correlation and leverage effect. We analyzed intraday prices for 10 stocks traded at the BM&FBovespa, responsible for 52.1% of the Ibovespa portfolio on Sept. 01, 2009. The data analysis confirms the stylized facts, whose behavior is consistent with what is observed in international markets.
