The objective of this study was to evaluate the species growing, to identify their growth pattern and to discuss the method quality in relation to plant reforestation. The survey was conducted after 32 months of planting seedlings, through sampling of fixed area by using plots, in which five sampling areas, selected to cover the entire length reforested, containing 200 individuals/sample area was used. Height and diameter were measured in all sampled plants, with a height greater than 1 (one) meter. Data were analyzed as a randomized block lineation (RBL), subjected to analysis of variance followed by Scott & Knott test at 5% of significance level, using the program SISVAR. Finally, it was concluded that pioneer species or those that have a short life cycle are considered ideal for deployment in early of reforestation due to fast growth; however they should have their management associated with not pioneer species or perennials species.

In 2006, the Ministry of Health created the National Policy on Integrative and Complementary Therapies in the Unified Health System. This study aimed to investigate the knowledge and acceptance of complementary and integrative therapies and pharmaceutical care by SUS users. The study was conducted in the pharmacy of a primary healthcare unit in São João da Mata city, Minas Gerais state, Brazil. A cross sectional study was performed qualitatively and quantitatively with three doctors and 35 service users. Of these, 100% did not know the complementary and integrative therapies. After clear and simple explanation by the researcher, 31.42% said they would accept the use of herbal medicine, 51.42% accepted acupuncture, 37.14% would use homeopathy and none would use crenotherapy. When asked about the pharmaceutical care, 45.71% said they had heard of this matter, 22.85% know what it is and 31.42% had never heard of it. When the three doctors who at the clinic were questioned, there was indifference, non-acceptance and acceptance, respectively. In conclusion, this study showed that the vast majority of respondents would accept the complementary and integrative therapies if they were offered by the health unit. In addition, users find important a greater role of the pharmacist. One need to implement outreach programs for patients and especially for prescribers of complementary and integrative practices.

Sensory science uses the human senses as instruments of measurement. Sensory analysis makes it possible to study organoleptic properties of products using a panel of assessors. Kermit and Lengard (2006) say that a good sensory panel should provide results that are accurate, discriminating and precise. Thus, in a successful analysis, it is key to have a set of robust tools for monitoring individual assessor's performances as well as the performance of the panel as a whole. The success of using a sensory panel depends on its performance, i.e., its ability to identify small differences between products in certain attributes with statistical significance. A good panel performance is achieved when each panelist discriminates between products (large product variability), repeats the assessments (small within-assessor variability) and agrees with all other panelists on the sensory sensation that is described by a particular attribute with certain strength (small between-assessor variability) (Derndorfer, Baierl, Nimmervoll, & Sinkovits, 2005). Evaluating unidimensionality of panel is essential for the efficient use of the sensory analysis. For such purpose, the Monte Carlo based test revealed to be powerful for large panel and sample sizes. It can be adopted as a tool for checking the efficiency of the training process of a panel. © 2009 Elsevier Ltd. All rights reserved. Source

Glasses were prepared in the binary system (100 - x)NaPO3-xMoO3 with x varying from 0 to 50 mol%. An increase in the MoO3 concentration promotes a strong absorption in the visible and near infrared attributed to Mo reduction during glass synthesis. X-ray absorption measurements were performed at the Mo K and L3 edges to investigate both the coordination number and oxidation state of Mo in these glasses. The evolution of the pre-peak observed at the K edge suggests that Mo atoms are six-fold coordinated in these glasses. This hypothesis was confirmed by data obtained at the Mo-L3-absorption edge. Since the final electronic states at the L3-absorption edge are mostly orbitals of d-character which are splitted by the ligand field, the amplitude of the d-orbital splitting could be estimated and the related coordination number of Mo obtained. Finally, the oxidation state of Mo could be related with a change of the white line intensity at the Mo-L3 edge. These results confirm that the optical absorption in the visible is due to Mo reduction and that transparent samples prepared by slow cooling contain less reduced Mo species. © 2009 Elsevier B.V.

The aim of this study was to determine the effects of previous administration of metyrapone (met) on the acute lung injury (ALI) induced by caecal ligation and puncture (CLP) and to explore met's relationship with endogenous glucocorticoids (GCs) as measured by inflammatory, oxidative and functional parameters. One hundred and thirty-five Wistar rats were divided into three main groups: Control (Naïve), Sham and CLP. The animals received pretreatment one hour before surgery. The Naïve group did not undergo any procedure or pretreatment. The Sham group only had the caecum exposed and was pretreated with saline. The CLP group was divided into three pretreatments: metyrapone (CLP met 50 mg/kg i.p.), dexamethasone (CLP dex 0.5 mg/kg i.p.) or saline (CLP sal equivalent volume of 0.9% NaCl). Analyses were performed after 6 and 24 h of sepsis. Previous administration of met significantly increased inflammatory cells, as well as myeloperoxidase (MPO) activity in the lung tissue and alveolar collapsed area, with consequent impairment of respiratory mechanics being observed compared to Sham and Naïve; CLP sal exhibited similar results to those of met. The met reduced corticosterone (CCT) levels and dramatically increased hydrogen peroxide (H2O2) levels in the lung tissue compared to CLP sal. Our results suggest that previous administration of met may have contributed to increased pulmonary oxidative stress and increased mortality by mechanisms dependent of endogenous GC. © 2015 International Journal of Experimental Pathology.
