Abstract: This study validated different extraction methodologies and compared the quantification of cholesterol by gas chromatography (GC) and high performance liquid chromatography (HPLC) in mg per 100 g of Italian-type salami and traditional bologna. The GC method used was direct saponification of the samples without derivatizations and the HPLC method was used to extract of the lipid samples. The GC limits of detection and quantification obtained for cholesterol were, respectively, 0.001 and 0.003 mg.g–1. The HPLC values were 0.005 mg.g–1 and 0.016 mg.g–1. The GC recovery rate was 97.10 ± 0.13 and that of HPLC was 93.33 ± 0.22. Comparison of the cholesterol quantity found using the two chromatographic techniques shows that both are capable of quantifying cholesterol in the foods. With regard to costs, analysis time, the cost/benefit relationship was better with gas chromatography than that obtained with high performance liquid chromatography.

Abstract: The purpose of this article was to investigate the practices adopted by companies for the treatment, attraction, andretention of women in its staff. The companies researched were the 150 Best Companies to Work For. In themethodological aspect, descriptive analyses of employees and companies were performed, as well as a contentanalysis and a description of frequencies of organizational practices. While some companies deny the differencesbetween men and women, others adopt the perspective of valuing the differences by performing actions such as:targets for hiring and promoting women, supporting the balance between family and career, incentives to healthcare. It can be noticed that, although the issue is in the agenda of discussions and developments in the society, theorganizations have developed their actions geared towards this public very slowly, including those that stand out asthe best places to work for in Brazil.
A fauna de parasitas do tambaqui, Colossoma macropomum (Cuvier, 1818) (Characiformes: Characidae) do médio rio Solim?es, Estado do Amazonas (AM) e do baixo rio Amazonas, Estado do Pará (PA), e seu potencial como indicadores biológicos

Journal of Food Research (JFR) , 2012, DOI: 10.5539/jfr.v2n1p109
Abstract: Fatty acids were quantified in oleaginous seeds: pistachio, almonds, European nuts, cashew nuts, hazelnuts, Brazil nuts, pecan nuts, and macadamia nuts. Three brands of each sample were purchased in three lots (n = 9). The proximate composition, energetic value, and fatty acids (FA) were determined by gas chromatography. All seeds had large amounts of total lipids and the highest contents (ca. 70%) were found in macadamia, pecan, and European nuts. The samples had significant amounts of crude protein. Pistachio and cashew nuts had the greatest amount (ca. 20%), as well as the largest carbohydrate contents (32%). All seeds were rather energetic, ranging from 600 to 760 Kcal.g-1. From seven to nine FA were identified and quantified, oleic (n-9) and linoleic (n-6) acids were the major acids. Essential fatty acid a-linolenic (n-3) was found in European nuts (except pistachio) with an n-6/n-3 ratio (4:1) that is very beneficial to health. Trans FA were also observed in salted roasted cashew nuts. The major saturated FA (SFA) was palmitic, stearic, and arachidonic acids, however, their amounts were much lower than those of polyunsaturated acids (PUFA) and monounsaturated acids (MUFA). European nuts had the greatest PUFA/SFA ratio (9), followed by almonds (3.6).

Brazilian Journal of Pharmaceutical Sciences , 2009, DOI: 10.1590/S1984-82502009000400013
Abstract: efforts to diminish the transmission of infections include programs in which disinfectants play a crucial role. hospital surfaces and medical devices are potential sources of cross contamination, and each instrument, surface or area in a health care unit can be responsible for spread of infection. the decimal reduction time was used to study and compare the behavior of selected strains of microorganisms. the highest d-values for various bacteria were obtained for the following solutions: (i) 0.1% sodium dichloroisocyanurate (ph 7.0) - e. coli and a. calcoaceticus (d = 5.9 min); (ii) sodium hypochlorite (ph 7.0) at 0.025% for b. stearothermophilus (d = 24 min), e. coli and e. cloacae (d = 7.5 min); at 0.05% for b. stearothermophilus (d = 9.4 min) and e. coli (d = 6.1 min). the suspension studies were an indication of the disinfectant efficacy on a surface. the data in this study reflect the formulations used and may vary from product to product. the expected effectiveness from the studied formulations shows that the tested agents can be recommended for surface disinfection as stated in present guidelines and emphasize the importance and need to develop routine and novel programs to evaluate product utility.
