title: Phylogenetic analysis, biofilm production, and antimicrobial resistance profile of Escherichia coli isolated from slaughtered pigs

description: ABSTRACT Enteric diseases of bacterial origin are frequent in the pig industry, of particular notoriety are the colibacillosis that mainly affect piglets and cause great damage to the swine industry worldwide. The aim of the study was to analyze phylogenetics, to detect biofilm production, and to determine antimicrobial resistance profile in 126 strains of Escherichia coli isolated from swabs obtained from fragments of the small intestines of 235 healthy pigs killed in slaughterhouses in Pernambuco (Brazil) using polymerase chain reaction (PCR), adherence to microplates test and disc diffusion technique. Of the analyzed samples, 88.10% (111/126) were classified in phylogenetic group B1; 4.76% (6/126) in group D; 3.97% (5/126) in group B2 and, 3.17% (4/126) in group A. Antimicrobial resistance rates observed were: lincomycin 100% (126/126), erythromycin 100% (126/126), chlortetracycline 94.44% (119/126), cephalothin 51.59% (65/126), ampicillin 38.89% (49/126), sulfamethoxazole + trimethoprim 37.3% (47/126), ciprofloxacin 19.84% (25/126), norfloxacin 14.29% (18/126), gentamicin 8.73% (11/126) and, chloramphenicol 5.55% (7/126). Multiple antibiotic resistance (MAR) ranged from 0.2 to 0.9. Of the strains tested 46.03% (58/126) produced biofilm, and 99.21% (125/126) of the strains exhibited multi-resistance. Further studies are required to elucidate the importance of each phylogenetic group in pigs and to prevent the propagation of multi-resistant E. coli strains.

title: Bovine Herpes virus type 1 (BoHV-1): Diagnosis method and its influence on spermatic quality in experimentally infected bulls

description: ABSTRACT Bovine Herpesvirus type-1 (BoHV-1) is a virus widely distributed in Brazil and worldwide, with a growing number of studies involving diagnostic methods and their impact on animal reproduction. The objective of this work was to identify the genetic material of BoHV-1 in the semen of experimentally infected bulls through the PCR technique, and to evaluate the influence of the virus on the sperm quality of these animals. The PCR technique was satisfactory, allowing for the identification of the presence of the genetic material of the virus in the semen of all the animals from 7 days post infection, with persistence of 21 to 28 days. Despite the presence of the BoHV-1 virus over a long period in the semen of the experimental animals, no deleterious effects were observed on the quality of either fresh semen or semen after the cryopreservation.

title: Evaluation of bulk-fill systems: microtensile bond strength and non-destructive imaging of marginal adaptation

description: Abstract The objective of this study was to investigate microtensile bond strength (MTBS) and interfacial adaptation (IA) of bulk-fill restorative systems bonded to dentin in Class-I-preparations. Box-shaped preparations (4-mm-long, 3-mm-wide, 2-mm-high) made in extracted molars, and Teflon matrix with the same dimensions positioned over the occlusal surface were restored, providing a total of 4-mm composite depth using three bulk-fill restorative systems: Tetric EvoCeram Bulk Fill with Tetric N-Bond (TEC/TNB), SureFil SDR Flow with XP Bond (SDR/XPB) and Filtek Bulk Fill Flowable Restorative with Scotchbond Universal (FBF/SBU); or incrementally restored with a conventional restorative system: Herculite Classic with OptiBond FL (HER/OBF). The specimens were sectioned into beams and the MTBS measured after 24-hours or one-year storage. For evaluation of IA, round-tapered tooth preparations (3-mm-diameter, 1.5-mm-deep) were made, restored with each material and their cross-sectional images were obtained after 24-hours using optical coherence tomography (OCT). The gap percentage for each restoration system was calculated using image analysis software. MTBS for both storage periods: HER/OBF=TEC/TNB=SDR/XPB&gt;FBF/SBU (ANOVA, Tukey’s post-hoc, P&lt;0.05) differed significantly among groups, which values were significantly reduced after one-year. SDR/XPB showed comparatively lesser gap formation at the tooth-interface after 24 hours (ANOVA, Dunnett’s T3 post-hoc, P&lt;0.05). For deeper restorations, bond strength of TEC/TNB and SDR/XPB can be equal to that of HER/OBF after 24-hours and one-year; however, in a shallower preparation, SDR/XPB showed greater initial interfacial adaptation.

title: IMMOBILIZATION OF RUTHENIUM SCHIFF BASE COMPLEX IN THE METAL-ORGANIC FRAMEWORK UiO-67

description: Zirconium-based metal-organic framework, UiO-67, was synthesized and used as support for the immobilization of the [RuCl2(ENAPY)] (ENAPY = N,N'-bis(7-metyl-2-pyridylmethylene)-1,2-diiminoethane)). The immobilized system exhibited violet-blue color. The {UiO-67/[RuCl2(ENAPY)]} was characterized by cyclic voltammetry, X-ray diffraction, UV-Vis, FTIR and X-ray photoelectron spectroscopy. The electrochemistry of the immobilized system is characterized by a reversible pair of waves at +0.40 V (vs NHE), ascribed to the Ru3+/2+ redox process. The electronic spectrum of the immobilized system is characterized by bands at 520 and 380 nm ascribed to a ligand-to-metal charge-transfer transitions {Ru2+(dπ) → ENAPY(pπ*)}. The IR bands of immobilized complex {1630 cm-1 (νasC=C), 1590 cm-1 (νasC=N), 1450 cm-1 (νsC=C), 1340 cm-1 (νsC=C)} are weak in comparison with the neat complex due to their low concentration in MOF cages. X-ray diffractogram of the immobilized system indicated that the crystallinity and morphology of UiO-67 was preserved during inclusion of ruthenium complex. The XPS spectra of UiO-67 and UiO-67/ruthenium complex shows a signal at 462 eV that can be ascribed to Ru 3p3/2 and at 400 eV ascribed to N 1s core level of the ruthenium Schiff base complex immobilized into MOF.

title: How do Archival Policies Arise: The 1st Auction of National Memory and the São Paulo State Archives System (Saesp)

description: ABSTRACT At the beginning of September 1983, after two days of exposition of letters, documents and manuscripts of the History of Brazil, the 1st Auction of National Memory would take place at Maksoud Plaza Hotel, in São Paulo. The documents, many of them of public nature, belonged to a private collector and, on that date, could not be auctioned due to an injunction founded on the Sphan Federal Decree-Law n. 25 of 1937. The event would finally be held on September 22, 1983, which consummation would have gone unnoticed by the press. This paper, sustained on the Auction catalog, on the stories about the event published at the time and on the theoretical reflections about the historical value and the nature and characteristic of documents, aims to discuss the legality of private collections formed by documents produced by public authorities as well as the impact of such an event to the creation of São Paulo State Archives System.

title: Antioxidant effect of the pequi oil (Caryocar brasiliense) on the hepatic tissue of rats trained by exhaustive swimming exercises

description: Abstract Increased oxygen consumption and activation of specific metabolic pathways during or after physical exercise lead to the formation of reactive oxygen and nitrogen species. An investigation was made into the effects of pequi oil supplementation in protecting liver cells against injury resulting from oxidative stress. The experiments involved 20 male adult Wistar rats ( Rattus norvegicus). The animals were divided into four experimental groups: Group 1: sedentary control group; Group 2: exercise control group; Group 3: supplemented sedentary group; and Group 4: supplemented exercise group. Supplementation consisted of pequi oil administered by oral gavage (400 mg). The animals of the exercised groups were subjected to 20 swimming sessions for 5 weeks (with progressive increase of 10 minutes until exhaustion). Samples were collected from the right hepatic lobe for histopathological analysis and determination of malondialdehyde levels. The histopathological analyses revealed that the animals of the exercised control group had moderate liver damage, while the animals of the supplemented exercised group had slight tissue damage, and the sedentary control and sedentary supplemented groups showed no tissue damage. The malondialdehyde levels showed higher and statistically significant in exercise control group when compared to the other evaluated groups (p&lt;0.05). In conclusion the supplementation with pequi oil had a protective effect on liver cells against damage caused by oxygen free radicals during strenuous exercise, as demonstrated by the indicator of lipid peroxidation.

title: From theory to practice, operating the clinical simulation in Nursing teaching

description: ABSTRACT Objective: To report the experience of the operationalization of clinical simulation as a pedagogical strategy in a subject of an undergraduate course in Nursing. Method: Clinical simulation cycles were carried out following the steps of action research, such as: planning, action, observation and reflection, from March 2014 to July 2015 with 10 professors and 44 students from a Primary Care and Mental Health subject of an undergraduate course in Nursing. Results: Five cycles of clinical simulation were performed, at the end of each cycle modifications were suggested by students and professors and the operation was adjusted to meet the needs of the subject. The main points of change were: professor role, logistics, equipment, debriefing model and preparation of “simulated patients”. Final considerations: The clinical simulation is a possible method to be operationalized in undergraduate course in Nursing, needs pedagogical and logistic planning as well as, sensitization of professors and students.

title: Feynman diagrams: The power of a picture

description: Abstract The purpose of this paper is to present a brief introduction to QED Feynman diagrams. We will start with a concise historical description of how this powerful diagrammatic technique was developed by Feynman. Next, the basic elements, i.e. propagators and vertices, which form the diagrams are presented. We discuss the physical meaning associated with the diagrams and list the main Feynman rules, which are needed for the calculations at the lower perturbation level. Then, the following three fundamental QED processes are analyzed: (i) Bhabha scattering, (ii) Compton and (iii) the annihilation of the electron-positron pair. Finally, we will discuss how the perturbative series, at higher order, is generated graphically for the specific case of the Moller scattering.
