title: Antimicrobial resistance, diarrheagenic and avian pathogenic virulence genes in Escherichia coli from poultry feed and the ingredients

description: ABSTRACT Diarrheagenic (DEC) and avian pathogenic Escherichia coli (APEC) are associated with intestinal and extra-intestinal infections (ExPEC), respectively. We aimed to analyze the antimicrobial susceptibility, gene encoding virulence factors associated to DEC and APEC, and phylogenetic classification in E. coli isolated from 320 samples of feed and ingredients. Antimicrobial susceptibility was performed using the disk diffusion method and Multiple Antibiotic Resistance (MAR) Index and Multi-Drug Resistance (MDR) were calculated. Phylogenetic classification was performed on samples harboring DEC and/or APEC virulence-associated genes. A total of 110 E. coli strains were isolated in 15% (49/320) of the evaluated inputs (n=13 vegetable meal; n=33 animal meal, n=3 feed). In general, the isolates showed the highest rates of antimicrobial resistance to sulfonamide and cefazolin and 18% (20/110) were multi-drug resistant. MAR index of feed samples was the highest (0.467). Six and five strains had APEC and DEC virulence-associated genes, respectively, and belonging to phylogenetic groups A and B1. These findings point to the need for strict microbiological control during the production process of these foods.

title: Analysis of the resistance of laser-made acrylic bone plates when subjected to different forces acting on the fracture focus

description: ABSTRACT The objective of this work was to analyze the resistance of acrylic bone plates, made with CO 2 laser cutter, when subjected to the forces acting on the fracture focus. Forty ovine femurs (Ovis aries) were used and 40 acrylic plates were prepared and evaluated in groups: In the OP Group, 20 fractured bones reduced with 20 acrylic plates were evaluated; in the PS Group, 20 acrylic plates were evaluated; and in the OS Group 20 intact and fresh bones were evaluated. All were submitted to mechanical tests of compression, bending, twisting and traction in an EMIC® 10000 universal testing machine. The tests were interrupted when the body of proof was fractured. The PS group supported a significantly higher compression load than the other OP and OS groups (13,255±290 N, 4,932±827 N and 8,681±303 N, respectively). Regarding the flexural test, the OS group was significantly more resistant, with a mean of 2,698±305 N, compared to the groups OP and PS that obtained 1,315±92 N and 1,537±37 N respectively. It is concluded that the laser-machined acrylic plates have inferior mechanical resistance to the femur of the ovine, however, due to the presented resistance, it shows potential to be implanted in bones with lower load demand.

title: Pasteurization effects on yield and physicochemical parameters of cheese in cow and goat milk

description: Abstract Cheese production is one of the most common forms of valorization of dairy production, adding value and preserving milk. Various types of cheese produced from raw and pasteurized milk are known worldwide. In the present work, we are interested in studying the effect of the type of milk (raw and pasteurized) of two species (cow and goat) on the yield and physicochemical characteristics of the fresh cheese. In the northeastern Algeria, on 5 cow farms and 3 goat farms; 5 raw and 5 pasteurized milk cheese manufacturing trials were conducted. The analysis of the results of the 80 samples of milk and cheese of both cow and goat species showed that the latter contained significantly more fat and protein than cow's milk and that pasteurized milk contained more protein than raw milk. As a result, actual cheese yield of goat cheese was higher than that of cows in pasteurized and raw milk. For higher yield, our result supported the use of pasteurized milk as a raw material in the manufacture of farmhouse cheese.

title: Agar and pomegranate seed oil used in a biodegradable coating composition for Formosa papaya

description: Abstract The use of biodegradable coatings to conserve fruits and vegetables stands out in the food industry. This study aims to evaluate the postharvest quality of papaya Formosa 'Tainung 01' submitted to different coating formulations, to establish the one that best maintains the postharvest quality. The fruits, distributed in a completely randomized design, received the coatings composed of aqueous solution of agar and pomegranate seed oil in the following compositions (with 6 treatments and 5 replicates): T1: 0.5% agar and 0.1 mL/L oil; T2: 1.0% agar and 0.2 mL/L oil; T3: 1.5% agar and 0.3 mL/L oil; T4: 2.0% agar and 0.4 mL/L of oil; T5: 2.5% of agar and 0.5 mL/L of oil; and T6: Control, uncoated. The experiment lasted ten days packing at 17.5 ± 0.6 °C and 55 ± 3, 2% RH. T4 provided better conservation of the quality attributes in papaya. Fruits in this treatment showed higher vitamin C content, higher soluble solids and total sugars, and lower titratable acidity, important characteristics for product acceptance. Besides, T4 better conserved the green (external) color of the fruits, while fruits submitted to the other treatments acquired a yellowish coloration.

title: Use of low density lipoprotein in different concentrations in diluent medium for cryopreservation of ovine semen

description: ABSTRACT The use of egg yolk makes it difficult to standardize extenders and presents biological hazards. Thus, this study evaluated different concentrations of low-density lipoprotein (LDL) to replace yolk extenders for production of sperm for cryopreservation in ovine. A control extender was used (CTR= 20% yolk) and five treatments, replacing the yolk by different ratios of LDL (T1= 6%; T2= 8%, T3= 12%; T4= 16%; T5= 20%) all based on TRIS-glycerol. For the study, two ejaculates from six Santa Ines breeding were used. Sixty days after cryopreservation, the samples were thawed and evaluated for total motility (MT, %) and progressive motility (MP, %), vigor (1-5) and the functional integrity (hyposmotic shock with distilled water, %) and structural (supravital dye eosin, %) of the sperm membranes. The evaluations of strength and membrane functionality didn’t differ (P&gt; 0.05) between groups. However, T4 (P&lt; 0.01) and T5 (P&lt; 0.05) groups were superior to the CTR for the MT, MP, and membrane structural integrity parameters, which confirms that LDLs can be efficient alternatives for yolk replacement in extenders for cryopreservation of ovine semen.

title: Antioxidant-mediated protective role of Hericium erinaceus (Bull.: Fr.) Pers. against oxidative damage in fibroblasts from Friedreich’s ataxia patient

description: Abstract Friedreich’s ataxia (FRDA) is a progressive neuromuscular disorder caused by substantial decrease of mitochondrial protein frataxin responsible for biogenesis of iron-sulphur clusters and protection from oxidative damage. In this study, we investigated the antioxidant activities of a standardized aqueous extract from fruiting bodies of Hericium erinaceus mushroom (HESAE) and its protective effects against oxidative damage induced by L-Buthionine sulfoximine (BSO) in fibroblasts derived from FRDA patient. The lactate dehydrogenase-based viability assay showed that FRDA fibroblast was sensitive to 12.5 mM BSO with a reduction of viability to 52.51 ± 13.92% after 24 h of BSO exposure. Interestingly, co-incubation with 32 mg/mL HESAE increased the viability to 85.35 ± 3.4%. Further, 12.5 mM BSO caused a decrease in the ratio of cellular reduced glutathione (GSH) to oxidised GSH (GSSG) that leads to cell death. Nevertheless, the damage was reduced by co-incubation with 32 mg/mL HESAE. Nuclear fluorescence staining revealed that 12.5 mM BSO induced cell death and the apoptosis was decreased by co-incubation with HESAE. These findings suggest the ability of HESAE in attenuating BSO-mediated cytotoxicity through maintenance of membrane integrity and optimal GSH/GSSG ratio, that are closely linked to its antioxidant activities. Further in vivo trials are highly warranted to clarify its potential benefits in management of FRDA.

title: Quality of pasta made of cassava, peach palm and golden linseed flours

description: Abstract The possibility of industrially producing new types of pastas based on other types of flour than wheat has raised interest for enabling the use of widely available materials and providing adequate products to persons with celiac disease. A mixture design was developed with the purpose of preparing a gluten-free dry using cassava starch, peach palm meal, and golden linseed while observing the nutritional value added and its technological properties. The pasta underwent assessments of its physicochemical and rheological characteristics. The drying temperatures studied were 60, 75, and 90 °C and the influence of those temperatures on pasta quality parameters and texture properties assessed. The percentage composition of the flours met the standards mandated by the Brazilian legislation and the pasta was classified as rich in fibers. The texture parameters of the pasta were influenced by the drying process, with the best results obtained at the lowest and highest temperatures studied.

title: The control of Maillard reaction in white grape molasses by the method of reducing reactant concentration

description: Abstract The aim of this study was to investigate the impact of removing sugar and/or amino groups by applying one ion exchange (Dowex 50Wx8) and two adsorbent (Activated Carbon and Amberlite XAD-16) resins to grape juice in the control of Maillard reaction. Grape juices, a control sample and separately applied with each resin, were concentrated up to 50, 60 and 70 °Bx and stored at three temperatures (50, 65 and 75 °C) for 10 days. HMF accumulation was lower in the grape juices which were treated with Amberlite or activated carbon throughout the boiling. Rate constant, activation energy and Q10 values indicated that activated carbon application has a decelerating effect on HMF formation in molasses, particularly molasses with 50 οBx. Dowex was more effective than Amberlite in controlling of brown pigment formation. Analysing the results of HMF and brown pigment, activated carbon was the best resin to control the Maillard reaction.

title: Quality pattern evaluation of frozen soursop pulps: an assessment based on chemical composition and chemometric analysis

description: Abstract In the present study, the physicochemical properties and mineral composition of commercially-frozen soursop pulps from the southern region of the state of Bahia, Brazil, were evaluated. The physicochemical parameters such as soluble solids (°Brix), acidity and pH were determined according to reference methodologies. For mineral composition evaluation, samples were digested in a closed microwave system and the elements K, P, S, Ca, Mg, Fe, Cu, Zn, and Mn were quantified through inductively coupled plasma optical emission spectrometry (ICP OES). Soluble solids content ranged from 4.77 to 15.37 °Brix among the different brands of analyzed frozen pulps. Titratable acidity (equivalent to citric acid) and pH ranged from 0.49 to 1.00 and 3.61 to 4.57, respectively. Some samples presented irregularities in regard to quality pattern established in the Brazilian legislation. The following range of concentration, in μg g-1, were found for essential elements: K (544-1761), P (44.3-139), S (71.8-174), Ca (24.3-77.0), Mg (47.2-132), Fe (1.40-4.05), Mn (0.32-1.22), Cu (0.30-0.88) and Zn (0.36-0.84). The use of principal component analysis (PCA) enabled a more in-depth data analysis, performing correlations between different variables and frozen pulp brands.

title: Cervical cancer: knowledge, attitude and practice on the prevention examination

description: ABSTRACT Objective: to evaluate the knowledge, attitude and practice of women on the cervical-uterine cancer screening and to investigate their association with sociodemographic variables. Method: a cross-sectional study, carried out from July to September 2015, with 500 women enrolled in the Basic Health Units of the Health District V, of the city of Recife-PE. For data collection, a semi-structured form was used. In statistical analysis, the Chi-square test and Fisher’s Exact Test were applied and, in the multivariate analysis, the Poisson model and Wald statistic. Results: the prevalence of adequate knowledge, attitude and practice was 35.2%, 98% and 70.6%, respectively. Adequate knowledge was associated with having no children, having a family income of two minimum wages and Spiritist/Afro-Brazilian religion. Conclusion: women carry out the examination, deem it necessary, but do not have adequate knowledge, which demonstrates the need for educational actions by nurses and other health professionals.

title: Life and death of Maracanã: the battle of the stadium in two acts

description: Abstract The paper recovers the main struggles over the resignification of the Maracanã stadium, which decisively influenced decisions on the destiny of this sports icon. The focus relies on two major historical moments: the planning period (1946-1950) and the refurbishment period (1999-2013), marked by controversies related to lifting of heritage protection. Newspaper archives are utilized to analyse the former, whereas institutional archives of Institute of National Historical and Artistic Heritage (IPHAN) are used for analysing the latter. The authors recognise the popular, public and monumental character of Maracanã as the core element comprising its identity.

title: What is superexploitation?

description: Abstract What is the superexploitation of labour power? How does superexploitation operate? What are its impacts on the working class? This paper aims to answer these questions, showing how the category introduced by Ruy Mauro Marini can be comprehended in accordance with the Marxist theory of value and how it relates to the determination of the value of labour power. The text has been written in order to contribute both to a broader understanding of this category and to present it for those who are not knowledgeable about the dependency debate.
