Histologic Analysis of Zafirlukast's Effect on Capsule Formation Around Silicone Implants: Some Considerations

We have read with profound interest the article by Bastos and colleagues entitled Histologic Analysis of Zafirlukast’s Effect on Capsule Formation Around Silicone Implants. We have truly enjoyed this study because it focuses on the very important issue of ongoing research toward pharmacologic therapy for the treatment of periprosthetic capsule contracture. The latter has an incidence in the range of 0.5% to 50% [3]. Despite persistent clinical and laboratory investigation, to date, no solution has been developed to solve or prevent this problem

Ecoturismo Recanto dona Elvira, Curitibanos - SC

Projeto acadêmico (graduação) - Universidade Federal de Santa Catarina. Campus Curitibanos. Ciências Rurais.O Ecoturismo vem crescendo desde a década de 70, tendo seu impulso dado final da década de 80. Desde então se pensa muito ecológicamente e em qualidade de vida, aumentando a demanda por esses serviços. Em Santa Catarina o campo de ecoturismo, turismo rural e até mesmo agroturismo têm vasto campo e belas extremamente exuberantes. No município de Curitibanos /SC não têm um campo ecológico para visitação, porém existe uma propriedade privada denominada Recanto Dona Elvira que poderia ser um forte atrativo no município e na região. A proposta deste trabalho é casar a ideia inicial dessa propriedade com ecoturismo, tornando-o mais ecológico possível, bem como o adequando às normas/legislações ambientais. Espera-se que seja possível a implantação deste projeto, pois com certeza será bastante rentável, atrativo e principalmente muito importante para conservação dos recursos naturais que nosso país possu

Advances in developing a new test method to assess spray drift potential from air blast sprayers

Drift is one of the most important issues to consider for realising sustainable pesticide sprays. This study proposes and tests an alternative methodology for quantifying the drift potential (DP) of air blast sprayers, trying to avoid the difficulties faced in conducting field trials according to the standard protocol (ISO 22866:2005). For this purpose, an ad hoc test bench designed for DP comparative measurements was used. The proposed methodology was evaluated in terms of robustness, repetitiveness and coherence by arranging a series of trials at two laboratories. Representative orchard and vineyard air blast sprayers in eight configurations (combination of two forward speeds, two air fan flow rates, and two nozzle types) were tested. The test bench was placed perpendicular to the spray track to collect the fraction of spray liquid remaining in the air after the spray process and potentially susceptible to drift out of the treated area. Downwind spray deposition curves were obtained and a new approach was proposed to calculate an index value of the DP estimation that could allow the differences among the tested configurations to be described. Results indicated that forward speed of 1.67 m/s allows better discrimination among configurations tested. Highest DP reduction, over 87.5%, was achieved using the TVI nozzles in combination with low air fan flow rate in both laboratories; conversely, the highest DP value was obtained with the ATR nozzles in combination with high air fan flow rate. Although the proposed method shows a promising potential to evaluate drift potential of different sprayer types and nozzles types used for bush and tree crops further research and tests are necessary to improve and validate this method.Postprint (published version

Sparse Discrete Ordinates Method in Radiative Transfer

The stationary monochromatic radiative transfer equation (RTE) is a partial differential transport equation stated on a five-dimensional phase space, the Cartesian product of physical and angular domain. We solve the RTE with a Galerkin FEM in physical space and collocation in angle, corresponding to a discrete ordinates method (DOM). To reduce the complexity of the problem and to avoid the "curse of dimension", we adapt the sparse grid combination technique to the solution space of the RTE and show that we obtain a sparse DOM which uses essentially only as many degrees of freedom as required for a purely spatial transport problem. For smooth solutions, the convergence rates deteriorate only by a logarithmic factor. We compare the sparse DOM to the standard full DOM and a sparse tensor product approach developed earlier with Galerkin FEM in physical space and a spectral method in angle. Numerical experiments confirm our finding

Status of Salerno Laboratory (Measurements in Nuclear Emulsion)

A report on the analysis work in the Salerno Emulsion Laboratory is presented. It is related to the search for nu_mu->nu_tau oscillations in CHORUS experiment, the calibrations in the WANF (West Area Neutrino Facility) at Cern and tests and preparation for new experiments.Comment: Proc.

Abdominoplasty: Thromboembolic Risks for Both Sexes

During surgical procedures, coagulation complications may occur. Discriminating factors are multiple and may vary because of the anatomical regions involved and because of preexisting diseases. The aim of this study was to analyze changes in such hematological parameters of patients undergoing conventional abdominoplasty with standard surgical procedures under general anaesthesia. For the study, 40 patients (20 men and 20 women) 30 to 60 years with normal coagulation assessments, no previous or current history of hemorrhagic or thrombotic disease, and no primary family history of such problems were selected. All the patients underwent conventional abdominoplasty surgical procedures. Analysis of the results suggests that immediately after surgery, in the absence of any preexisting hypo- or hypercoagulability state, there was no circumstantial modification in coagulation factors considered predictive for thromboembolic risk. However, an interesting difference between male and female patients was noted. In the male group, there was an insignificant uniform downward trend of all values immediately after surgery. In conclusion, women are less hypercoagulative than men in the postoperative period, suggesting that women have limited protection from the development of thromboembolic complications immediately after surgical procedures.During surgical procedures, coagulation complications may occur.

Influence of gender, sexual orientation, and need on treatment utilization for substance use and mental disorders: Findings from the California Quality of Life Survey

Abstract Background Prior research has shown a higher prevalence of substance use and mental disorders among sexual minorities, however, the influence of sexual orientation on treatment seeking has not been widely studied. We use a model of help-seeking for vulnerable populations to investigate factors related to treatment for alcohol or drug use disorders and mental health disorders, focusing on the contributions of gender, sexual orientation, and need. Methods Survey data were obtained from a population-based probability sample of California residents that oversampled for sexual minorities. Logistic regression was used to model the enabling, predisposing, and need-related factors associated with past-year mental health or substance abuse treatment utilization among adults aged 18–64 (N = 2,074). Results Compared with individuals without a diagnosed disorder, those with any disorder were more likely to receive treatment. After controlling for both presence of disorder and other factors, lesbians and bisexual women were most likely to receive treatment and heterosexual men were the least likely. Moreover, a considerable proportion of sexual orientation minorities without any diagnosable disorder, particularly lesbians and bisexual women, also reported receiving treatment. Conclusion The study highlights the need to better understand the factors beyond meeting diagnostic criteria that underlie treatment utilization among sexual minorities. Future research should also aim to ascertain the effects of treatment provided to sexual minorities with and without diagnosable disorders, including the possibility that the provision of such treatment may reduce the likelihood of their progression to greater severity of distress, disorders, or impairments in functioning.</p
