Lipopolysaccharides (LPS) released from Gram-negative bacteria after infection initiate an exagerated responsethat leads to a cascade of pathophysiological events termed sepsis. Monocytes or macrophages produce many of the media-tors found in septic patients. Targeting of these mediators, especially tumor necrosis factor (TNF)-. and nitric oxide (NO),has been pursued as a mean of reducing mortality in sepsis. Bovine dialyzable leukocyte extract (bDLE) is a dialysate of aheterogeneous mixture of low-molecular-weight substances released from disintegrated leukocytes of the blood or tissue lym-phoid. In this study, to determine whether bDLE modulates NO and pro-inflammatory cytokine production, murine peritonealmacrophages were treated with bDLE (0.05 or 0.5 U/mL) before LPS (20 mg/mL) stimulation, and also LPS-stimulated murineperitoneal macrophages were treated with bDLE (0.05 or 0.5 U/mL) at 0, 4, 8, 12, and 24 hours. The bDLE significantly de-creased NO production, and also decreased TNF-. and interleukin (IL)-6 but increased IL-10 production in LPS-stimulatedmurine peritoneal macrophages. Our results demonstrate that bDLE plays an important role in modulating TNF-., IL-6, andNO production through IL-10, and this may offer therapeutic potential in clinical endotoxic shock.

Transportation assets play a crucial role in the development of society, being the backbone of socio-economic development but also a key contributor to climate change. Transportation asset management systems include a set of tools to support agencies in the decision on which infrastructure of a network should be preserved, maintained and/or rehabilitated. However, the evaluation of these networks has traditionally focused on economic and technical aspects of interurban networks. Considering the direct impacts on the evolution of social and natural environments, management of these assets needs to be sustainable. This article proposes a methodology for the sustainable management of transportation assets, by integrating technical, economic, environmental, social and political aspects in the Life Cycle-Assessment of a network. The methodology proposes a framework that integrates these aspects in the various components and processes considered in a management system. It incorporates a Geographic Information System as the main platform to pursue the socio-political analysis based on geographical referencing of formalized variables. The proposed framework is applied to a case study for the management of an urban pavement network. Outcomes demonstrate that it is possible to integrate sustainable aspects, despite their diverse nature, in a management system supported by a Geographic Information System.

The use of odor dispersion modeling have gained popularity in recent years due to its capacity to analyze the amount of odor transport in the atmosphere. Especially, this technology allows researchers to determine the appropriate separation distances between the livestock farms and the nearby community. Most of the previously developed models were based on Gaussian dispersion theory which was commonly used in industrial odor dispersion. However, as the Korean Peninsula is comprised of complex topographical conditions, the use of this model becomes limited. To supplement these limitations, this study aimed to develop a computational fluid dynamics (CFD) based model to predict odor dispersion and analyze the effect of various environmental factors including wind speed, wind direction, atmospheric stability and ventilation rate. The developed three-dimensional CFD model was validated by comparing the field-measured data with the CFD-computed results. A total of 288 cases scenario were simulated and stored and analyzed using vectors and contours. The simulation results were integrated with forecasting system to predict odor transport. Based on the result analysis, the calculated odour dispersion distance, odor area and odour concentration can significantly vary depending on the scenario being analyzed. From the statistical analysis, the most influential factor that affects odor dispersion includes wind speed and atmospheric stability with a relative weight scale of 43.21% and 22.26%, respectively.

Ethanol fuel production from lignocellulosic biomass is emerging as one of the most important technologies for sustainable development. To use this biomass, it is necessary to circumvent the physical and chemical barriers presented by the cohesive combination of the main biomass components, which hinders the hydrolysis of cellulose and hemicellulose into fermentable sugars. This study evaluated the hydrolytic capacity of enzymes produced by yeasts, isolated from the soils of the Brazilian Cerrado biome (savannah) and the Amazon region, on sugarcane bagasse pre-treated with H2SO4. Among the 103 and 214 yeast isolates from the Minas Gerais Cerrado and the Amazon regions, 18 (17.47%) and 11 (5.14%) isolates, respectively, were cellulase-producing. Cryptococcus laurentii was prevalent and produced significant β- glucosidase levels, which were higher than the endo- and exoglucanase activities. In natura sugarcane bagasse was pre-treated with 2% H2SO4 for 30 min at 150oC. Subsequently, the obtained fibrous residue was subjected to hydrolysis using the Cryptococcus laurentii yeast enzyme extract for 72 h. This enzyme extract promoted the conversion of approximately 32% of the cellulose, of which 2.4% was glucose, after the enzymatic hydrolysis reaction, suggesting that C. laurentii is a good β-glucosidase producer. The results presented in this study highlight the importance of isolating microbial strains that produce enzymes of biotechnological interest, given their extensive application in biofuel production.

The application of emerging technologies suchas ultrasound, microwaves and high hydrostatic pressure,allows the extraction of compounds in a sustainable mannerfrom a vegetable matrix with a high value such asjackfruit leaf proteins (Artocarpus heterophyllus Lam). Currently, the main method of protein extraction is basedon the precipitation with the use of an aggressive solvent,therefore it is necessary to optimize extraction methodswith a minimum waste production. In the protein extractionof jackfruit leaves, we obtained a content of 84.1 mg/gusing solvents. On the other hand, emergent extractionssuch as ultrasound, microwaves, and high hydrostaticpressure showed concentrations of 96.3, 95.6 and147.3 mg/g, respectively. In addition, we found that thebest extraction agent was 0.5 M NaCl, offering a range ofpossibilities that support green technologies as an imperativechange in the food industry.

PURPOSE. The aim of this study was to define a color space of non-vital teeth and to compare it with the color space of matched vital teeth, recorded in the same patients. MATERIALS AND METHODS. In a group of 218 patients, with the age range from 17 to 70, the middle third of the buccal surface of 359 devitalized teeth was measured using a clinical spectrophotometer (Vita Easyshade Advance). Lightness (L*), chromatic parameters (a*, b*), chroma (C*), hue angle (h) and the closest Vita shade in Classical and 3D Master codifications were recorded. For each patient, the same data were recorded in a vital reference tooth. The measurements were performed by the same operator with the same spectrophotometer, using a standardized protocol for color evaluation. RESULTS. The color coordinates of non-vital teeth varied as follows: lightness L*: 52.83–92.93, C*: 8.23–58.90, h: 51.20–101.53, a*: -2.53–24.80, b*: 8.10–53.43. For the reference vital teeth, the ranges of color parameters were: L*: 60.90–97.16, C*: 8.43–39.23, h: 75.30–101.13, a*: -2.36–9.60, b*: 8.36–39.23. The color differences between vital and non-vital teeth depended on tooth group, but not on patient age. CONCLUSION. Non-vital teeth had a wider color space than vital ones. Non-vital teeth were darker (decreased lightness), more saturated (increased chroma), and with an increased range of the hue interval. An increased tendency towards positive values on the a* and b* axes suggested redder and yellower non-vital teeth compared to vital ones.

PURPOSE. The aim of the present study was to evaluate if a smaller morse taper abutment has a negative effect on the fracture resistance of implant-abutment connections under oblique compressive loads compared to a conventional abutment. MATERIALS AND METHODS. Twenty morse taper conventional abutments (4.8 mm diameter) and smaller abutments (3.8 mm diameter) were tightened (20 Ncm) to their respective implants (3.5 * 11 mm) and after a 10 minute interval, implant/abutment assemblies were subjected to static compressive test, performed in a universal test machine with 1 mm/min displacement, at 45 degree inclination. The maximum deformation force was determined. Data were statistically analyzed by student t test. RESULTS. Maximum deformation force of 4.8 mm and 3.8 mm abutments was approximately 95.33 kgf and 95.25 kgf, respectively, but no fractures were noted after mechanical test. Statistical analysis demonstrated that the evaluated abutments were statistically similar (P=.230). CONCLUSION. Abutment measuring 3.8 mm in diameter (reduced) presented mechanical properties similar to 4.8 mm (conventional) abutments, enabling its clinical use as indicated.

Background: To investigate the prevalence of and factors associated with performance of annual mammography by women above 40 years of age. Materials and Methods: This cross-sectional retrospective study was conducted at an oncology reference service in Southern Brazil from October 2013 to October 2014 with 525 women aged 40 years or older. Results: The prevalence of annual mammography was 54.1%; annual mammographic screening was performed for women without private medical insurance, who were under hormone replacement therapy and who had used contraception in the past. An association was found between non-performance of breast clinical and self-examination and non-performance of mammographic screening. Conclusions: Use of mammography for breast cancer screening in the public health care setting proved to be accessible; nevertheless, the proportion of screened women was low, and they exhibited poor adherence to the basic measures of care recommended for breast assessment. Thus, control of breast cancer requires implementing actions targeting the population most vulnerable to non-adherence to screening in addition to continuously monitoring and assessing that population to reduce the prevalence of this disease.
