Cellular viability and nitric oxide (NO) production by J774 macrophages in the presence of orthodontic archwires  [PDF]
Carlos E. P. Toledo, Maria A. Souza, Marcelo R. Fraga, Luiz C. Ribeiro, Ana P. Ferreira, Robert W. F. Vitral
Journal of Biomedical Science and Engineering (JBiSE) , 2012, DOI: 10.4236/jbise.2012.55032
Abstract: To assess, in vitro, the cellular viability in a murine macrophage cell line J774 with 9 different orthodontic wires and to evaluate the effects of its NO production. To assess cellular viability by MTT: 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide assay in the cell line J774 with 9 different orthodontic wires and quantify NO production by these macrophages. Cell cultures were evaluated at 24, 48 and 72 hours. There was no significant difference of the means of cellular viability between the control and the group of wires in the respective time intervals. In the comparison with the control group, there was significant difference in the NO production in groups 1, 6, and 9 at 24 hours interval. Group 8 showed significant difference in relation to the control group at final time interval. Cellular viability in all groups was higher at the final time interval than at the initial time interval. This increase was significant in the control group. In the material groups, the final mean of cellular viability at 72 hours showed no significant difference when compared with the control group. NO production in all groups was higher at the final time interval than at the initial time interval. This increase was significant in the control group. In the material groups, the final mean of NO production at 72 hours was only significant in group 8 (betatitanium) when compared with the control group.

Abstract:

Management evaluation of Panicum maximum cv. massai (Massai guineagrass) under deferment contributes as a strategic reserve of forage in the Brazilian semi-arid region. The objective of this study was to evaluate biomass production and nutritive value of massai guineagrass in an area of thinned caatinga vegetation in two deferment periods (60 and 90 days after plot-leveling cut) and four use periods (30, 60, 90 and 120 days after the end of the rain season), in a random blocks design arranged in a split-plot (2 × 4), with three replications. Extending the deferment period of massai guineagrass promoted elevation of the biomass components, but compromised the pasture quality due to increasing stem biomass. The massai guineagrass deferred 30 days after raining season started and should use 90 days after raining season ended to ensure a forage supply of appropriate nutritional value. The increase in relative air humidity and the occurrence of rainfall after water restriction stimulate regrowth, resulting in improved nutritional value of the grass.

Abstract: The participation of the father in the breastfeeding must be culturally assimilated by health professionals and by the society. This is a bibliographical descriptive and documentary study, aims to present the theoretical production in relation to the father's involvement breastfeeding in and public policy. The collected data was from 1992 to 2006 and the sources for collection were LILACS; SCIELO; MEDLINE; ADOLEC and BDEN from the Health Virtual Library– BIREME in September 2007 with the keywords: Paternity, Breastfeeding and Public Policies. Among the 140 studies found, one, published in a international magazine recommended other directions in research and Public Policies to encourage the father’s involvement. We hope that this research offers reflections and changes in the practice of nurses to take care/care in maternal and child attention in which the father is included as a participant in breastfeeding and in the mother’s and child care. Urge activities and publications to recognize the father in this process.

Open Journal of Business and Management (OJBM) , 2015, DOI: 10.4236/ojbm.2015.31004
Abstract: While Internet has been achieving its omnipresence worldwide and offering to companies the opportunity of trading in a “no-borders” market, global brands, and those aspiring to become global, face the challenge of dealing with significant cultural differences. Emergent economies account for one of the greatest opportunities for global brands interested in extending their business overseas through digital channels. Among these economies, Brazil has been receiving special focus lately as a promising consumer market. Working from a theoretical point of view through literature and simultaneously examining companies as potential paradigms, this study aims to provide suggestions for global brands interested in targeting the Brazilian market through effective cross-cultural digital branding strategies. The results are valuable insights about how to establish better communication with Brazilian consumers and also offer some guidance to help marketers to keep brands desired and admired in Brazil. It was mainly concluded that global brands should find out the right balance between a standardized and an adapted cultural approach in order to establish a trust-worthy proximity with Brazilian consumers on the digital environment.
