title: Facebook as a tool to promote radiology education: expanding from a local community of medical students to all of South America

description: Abstract Objective: To assess the feasibility of Facebook to promote a radiology education project and to expand it from our university community of medical students to a wider audience. Materials and Methods: A group of 12 medical students created a Facebook page in June 2015, to contribute to radiology education in our university. From August 2015, clinical cases, including a brief explanation of clinical findings, along with different imaging modalities, were posted weekly and subscribers were encouraged to choose the most appropriate diagnosis. All cases were followed by the appropriate answer and an explanation to highlight imaging findings and diagnosis. Aiming to reach a larger audience, we also shared cases to a public Latin-American Facebook group, comprising a collective total of 28,182 physicians and medical students. Using the Facebook Insights tracking tool, we prospectively analyzed subscriber interaction with our page for 14 months. Results: During the period analyzed, 35 cases were posted. The most common imaging modalities were X-ray (n = 15) and computed tomography (n = 13). Before we began posting the weekly cases, our page had 286 likes. By October 2016, that number had grown to 4244, corresponding to an increase of 1484% and eight times the size of the medical student community at our institution (n = 530). Medical students made up most (76%) of the subscribers, followed by radiology residents (6%). An excellent or moderate contribution to personal image interpretation skills was reported by 65.3% and 33.1% of the users, respectively. Conclusion: Creating a Facebook page and posting weekly clinical cases proved to be an effective method of promoting radiology education.

title: Effects of fennel seed supplementation of ration on performance, egg quality, serum cholesterol, and total phenol content of egg yolk of laying quails

description: ABSTRACT The objective of this research was to evaluate the effects of fennel seed (Foeniculum vulgare Mill.) supplementation of ration on performance, egg quality, and serum cholesterol of laying quails during an eight-week period. For this purpose, 96 quail (Coturnix coturnix japonica) of 16 weeks of age were evenly separated into one control group and three treatment groups. Each group was divided into four replicates, each containing six quail. The fennel seeds (Foeniculum vulgare) were added to the diets of the first, second, and third treatment groups at levels of 0.3, 0.6, and 0.9%, respectively. No significant effect of dietary fennel seed supplementation was recorded on body weight, feed intake, egg production, and egg weight. Feed efficiency (kg feed per kg egg) of the 0.6% treatment group was negatively affected by fennel seed supplementation; however, kilogram of feed:dozen egg ratio was not affected when compared with the control group. The effects of dietary treatments on shape index, albumen height, albumen index, Haugh unit, yolk index, yolk colour, blood cholesterol level, and total phenol content of egg yolk had no significance. Dietary fennel seed do not affect the egg quality and blood cholesterol level of laying quail. The amount of 0.3, 0.6, and 0.9% dietary fennel seed supplementation do not have any adverse effect on performance and egg quality of laying quail.

title: INFLUENCE OF BREASTFEEDING ON CONSUMPTION OF SWEETENED BEVERAGES OR FOODS

description: ABSTRACT Objective: To verify whether breastfeeding is associated with lower prevalence of consumption of sweetened beverages or foods in infants. Methods: This is a cross-sectional study with data collected from the Survey on Prevalence of Breastfeeding conducted in Brazilian municipalities in 2008. A representative sample of 14,326 infants aged 6 to 11.9 months of age, residents of 75 municipalities in the State of São Paulo, Southeastern Brazil, was studied. The influence of breastfeeding on the consumption of sweetened beverages or food products was analyzed by multilevel Poisson regression. Variables with p&lt;0.20 in the crude analysis were included in the multilevel analysis. Results: Most infants were on breastfeeding (56.1%). The prevalence of sweetened drinks or foods consumption was 53.3%. The consumption of sweetened products was shown to be less prevalent among breastfed infants after adjustment for confounding factors (PR 0.87; 95%CI 0.83-0.91). Conclusions: Breastfeeding was associated with lower consumption of sweetened beverages or foods. As an additional effect of actions aimed at promoting breastfeeding, a decrease in intake of sweetened products is expected among infants.

title: Quality of horse F(ab′)2 antitoxins and antirabies immunoglobulins: protein content and anticomplementary activity

description: Abstract Background Among other applications, immunotherapy is used for the post-exposure treatment and/or prophylaxis of important infectious diseases, such as botulism, diphtheria, tetanus and rabies. The effectiveness of serum therapy is widely proven, but improvements on the immunoglobulin purification process and on the quality control are necessary to reduce the amount of protein aggregates. These may trigger adverse reactions in patients by activating the complement system and inducing the generation of anaphylatoxins. Herein, we used immunochemical methods to predict the quality of horse F(ab′)2 anti-botulinum AB, anti-diphtheric, antitetanic and anti-rabies immunoglobulins, in terms of amount of proteins and protein aggregates. Methods Samples were submitted to protein quantification, SDS-PAGE, Western blot analysis and molecular exclusion chromatography. The anticomplementary activity was determined in vitro by detecting the production of C5a/C5a desArg, the most potent anaphylatoxin. Data were analyzed by one-way ANOVA followed by Tukey's post-test, and differences were considered statistically significant when p &lt; 0.05. Results Horse F(ab′)2 antitoxins and anti-rabies immunoglobulin preparations presented different amounts of protein. SDS-PAGE and Western blot analyses revealed the presence of protein aggregates, non-immunoglobulin contaminants and, unexpectedly, IgG whole molecules in the samples, indicating the non-complete digestion of immunoglobulins. The chromatographic profiles of antitoxins and anti-rabies immunoglobulins allowed to estimate the percentage of contaminants and aggregates in the samples. Although protein aggregates were present, the samples were not able to induce the generation of C5a/C5a desArg in vitro, indicating that they probably contain acceptable levels of aggregates. Conclusions Anti-botulinum AB (bivalent), anti-diphtheric, antitetanic and anti-rabies horse F(ab′)2 immunoglobulins probably contain acceptable levels of aggregates, although other improvements on the preparations must be carried out. Protein profile analysis and in vitro anticomplementary activity of F(ab′)2 immunoglobulin preparations should be included as quality control steps, to ensure acceptable levels of aggregates, contaminants and whole IgG molecules on final products, reducing the chances of adverse reactions in patients.

title: Environmental perception of fishermen: use and conservation of fisheries resources

description: Abstract: The principal aim was to assess the environmental perception of the fishermen, and implement educational activities, on an island in Brazil. Twelve people between the ages of 23 and 63 were interviewed, of whom 75% were male, and 58.33% did not complete their elementary education. Regarding social benefits, 33.33% receive a family allowance and 16.66% receive the so-called 'green allowance' (financial assistance to extremely poor families who live in areas of environmental preservation). Fishing remains the main economic activity (58.73%). The most common types of fishing gear are the 'zangarias' (41.66%) and 'muruadas' (41.66%), used to catch white shrimp (Litopenaeus schmitti), the main resource traded on the island (83.33%). All those interviewed reported a change in the size and weight of the catch in recent years (100%), and 75% attribute this to the types of trap used. Talks, films and booklets, as environmental education activities, contributed to community awareness. The population is familiar with the effects of fishing traps, and shows an interest in changing the situation.

title: Numerical analysis of glued laminated timber beams reinforced by Vectran fibers

description: Abstract Some factors, such as environmental actions and load increases, can cause a necessity to restore a structural element. An efficient method typically used is to reinforce the structure with a high mechanical property´s material. In this study, a numerical approach of glued laminated timber beams reinforced with the following synthetic fibers: Vectran®, carbon and glass fibers was developed. Vectran® fibers have high performance and are employed in various areas, but not yet as a structural reinforcement. The beam models were designed on Ansys software-version 12 and the results were analyzed regarding the maximum stresses and displacements. When compared to unreinforced beam, the fiber reinforcement absorbed a great part of the acting stresses, reducing the tensile stress and the displacement maximum values. Considering mechanical properties and the material cost, Vectran® fiber is an interesting alternative for structural reinforcement, fitting its mechanical performance at an intermediate level between carbon fiber and glass fiber.

title: LEWIS ACID SITES OF Mg2+-MODIFIED POLYSTYRENE SULFONIC ACID RESIN CATALYSYS FOR SYNTHESIS OF DIBUTYL SUCCINATE

description: The polystyrene sulfonic acid resin catalysts were fabricated, containing elements of Cl and Mg through oxidization and impregnation, and they were characterized by EDS, FT-IR spectra, Py-IR spectra, UV spectra, XPS and TGA to investigate their physiochemical properties. The catalytic performances of these catalysts were examined in the esterification reaction of succinic acid with n-butanol, and the catalytic results showed that modified resins exhibited the highest catalytic activity and achieved a high yield of dibutyl succinate (91.6%) in addition, the modified resin generated new Lewis acid sites and showed significantly higher thermal stability. The experimental results demonstrated that the Mg2+ coordinated with a sulfonic acid group to form stable active sites, which effectively decreased the deactivation caused by the thermal degradation of sulfonic acid. Moreover, the monomer structures of polystyrene sulfonic acid resin and modified polystyrene sulfonic acid resin have been modelled using B3LYP/6-311G(d,p) approximation.

title: Effects of Ananas comosus leaf powder on broiler performance, haematology, biochemistry, and gut microbial population

description: ABSTRACT The objective of our study was to evaluate the effects of pineapple (Ananas comosus) leaf powder (PLP) on broiler performance. One hundred male broiler chicks (aged one day) were divided into five groups consisting of four pens as replicates, which were treated with basal diet (normal control); basal diet supplemented with 1, 2, and 3% PLP; or 50 mg/kg of zinc bacitracin (ZnB) as a positive control for 35 days. Body weights were significantly increased by 1.06, 5.67, 13.15, and 11.92%, respectively, and feed conversion ratios were decreased by 2.36, 8.49, 12.06, and 11.43%, respectively, in 1, 2, 3% PLP- and ZnB-supplemented groups, compared with the normal control group. Notably, the 2 and 3% PLP supplementations had beneficial effects on broiler performance, similar to that of the positive group. Haematological parameters, such as red blood count, haemoglobin, and haematocrit, were improved in the 3% PLP-supplemented group, but no significant differences in white blood count and its differential count were observed. The serum biochemical parameters, such as creatinine and blood urea nitrogen, were found to be decreased in the 2 and 3% PLP-supplemented groups, compared with the normal control group. Finally, 2 and 3% PLP supplementations dramatically decreased the caecal coliform and Escherichia coli populations, but increased the lactobacillus population. Taken together, our results suggest that PLP improves the performance of broilers and balances the gut microbial population. Therefore, PLP can be used as a supplement in the diet of broilers.
