title: Oral lesions secondary to visceral leishmaniasis in a dog with endogenous hyperadrenocorticism: case report

description: ABSTRACT The objective of the present study was to report a case of visceral leishmaniasis with mucosal presentation in a dog with hyperadrenocorticism. A canine, male, Poodle, 11 years old, was attended with a history of dysphagia, halitosis, and sialorreia. The physical examination revealed generalized lymphadenomegaly and cutaneous alterations such as hair loss, comedones, telangiectasia, and cutaneous atrophy. Futhermore, the animal also had localized oral formations on the tongue. From the hematological and biochemical tests performed, the only alteration was alkaline phosphatase elevation (1724u / L). The low dose dexamethasone suppression test was performed to investigate hyperadrenocorticism and found a positive result. In addition, cytological exams of lymph nodes, bone marrow and oral formations were also performed, and the presence of amastigote forms of Leishmania sp. were observed in all samples. The animal was submitted to incisional biopsy of the oral formations and the histopathological analysis showed a granulomatous inflammation with presence of large quantity of microorganisms morphologically compatible with amastigotes forms of Leishmania sp. within the inflammatory cells. Faced with clinical findings and complementary exams, a case of leishmaniasis with atypical mucosal manifestation, associated with hyperadrenocorticism, was diagnosed, and this endocrinopathy could have been a predisposing factor to this infectious-contagious disease.

title: Ractopamine concentration on the lipid profile of swine fat and meat

description: ABSTRACT: This study was conducted to evaluate the effect of ractopamine concentrations on swine fat and meat lipid profiles. Ninety finishing barrows, initially weighing 71.9±4.4kg, were distributed in a randomized block design in three ractopamine concentrations (0, 10 and 20ppm) with fifteen replicates of two animals in each. Gas chromatography was used to analyze the lipid profiles of backfat and meat. The inclusion of ractopamine in the diet changed (P&lt;0.05) α-linolenic acid and eicosatrienoic acid concentrations in the backfat but did not affect (P&gt;0.05) any of the other fatty acids or indexes evaluated. In the meat, a significant effect (P&lt;0.05) was observed on nine fatty acids evaluated, with a decrease (P&lt;0.05) in lauric, myristic, and palmitic fatty acids, and an increase (P&lt;0.05) in linoleic, γ-linolenic, dihomo-γ-linolenic, and eicosapentaenoic acid. Ractopamine also affected (P&lt;0.05) the concentration of α-linolenic and arachidonic acid in the meat (P&lt;0.05). The indexes evaluated were also affected (P&lt;0.05). Addition of 10ppm decreased the saturated fatty acid concentration, atherogenic index, thrombogenic index and omega 6: omega 3, while it increased unsaturated and polyunsaturated fatty acids concentrations. Ractopamine addition had less effect on the backfat than on the meat, and the 10ppm level improved the meat lipid profile.

title: Cassava starch-based reinforced eco-compatible materials with agronomic applications

description: ABSTRACT Plastic mulch is used in various crops production in order to increase yield, extend growing season, weed control, increase fertilizers efficiency and improve soil conditions. However, since such plastics removal and disposal represent not only an additional cost, but also a source of environmental pollution, interest in starch-based materials as a viable alternative for this and other agricultural applications has raised in the last years. In this regard, films based on starch present several advantages: biodegradability, renewable-resource based and relatively low cost. The present work exhibit the results obtained in the development and study of biodegradable materials based on cassava starch reinforced with cassava bagasse, evaluating their biodegradability in soil and the effects of their exposure to UV -visible light cycles (photo-periods) for 60 days. Fibre inclusion resulted in more opaque and coloured films, with water vapour permeability a 53% higher, and increased maximum tensile strength and elastic modulus. During storage no changes in both optical properties and solubility of the films were observed. However, the materials showed signs of aging as its rigidity and crystallinity increased. Films without fibre addition showed a marked rise in the elastic modulus and maximum stress at break while their elongation at break decreased; such effects were less noticeable in reinforced films. In order to evaluate the materials biodegradability, samples were buried in fertile soil under controlled environmental conditions. After 42 days, it was observed that both reinforced materials and controls had a weight loss greater than 60%, evidencing their biodegradability. In conclusion, it is possible to develop eco-compatible cassava starch reinforced materials with potential agronomic uses.

title: Synthesis of poly(ethyl methacrylate-co-methyl methacrylate) obtained via ATRP using ruthenium benzylidene complexes

description: Abstract Atom-Transfer Radical Copolymerization (ATRP) of methyl methacrylate (MMA) and ethyl methacrylate (EMA) under different reaction conditions was conducted using Grubbs 1st ( 1) and 2nd (2) generation catalysts. Initially, the study focused on the reactivity of the catalysts in ATRP of EMA individually, then the syntheses of poly(MMA-co-EMA) were also conducted in different mixtures of monomers ([MMA]/[EMA] = 100/200 and [MMA]/[EMA] = 200/100). Conversion and semilogarithmic kinetic plots as a function of time were related to the different catalysts and reaction conditions. The values of Mn and PDI also changed when different catalysts were used in the presence of Al(OiPr)3, and more controlled polymerizations were achieved using 1. In the syntheses of poly(MMA)-co -(EMA), conversion of 60% was reached for both catalysts at different [MMA]/[EMA] ratios for 16 h; however, for shorter time, 4 h, better conversion values were obtained using 1 as catalyst for both [MMA]/[EMA] = 100/200 or 200/100.

title: Drift of 2,4-D and dicamba applied to soybean at vegetative and reproductive growth stage

description: ABSTRACT: The introduction of dicamba and 2,4-D-resistant soybean will increase the use of auxin herbicides for management of herbicide-resistant weeds, increasing risk of drift in non-target crops. The field experiment was conducted in 2016/17 to evaluate injury, growth, yield, germination and seeds vigor of soybean effects to simulated drift of 2,4-D and dicamba applied to soybean at the V3 and R2 growth stages. To simulate drift, 2,4-D was applied at 0; 5.16; 10.4; 20.8 e 41.5g ae ha-1 and dicamba at: 0; 3.7; 7.4; 14.9 e 29.8g ae ha-1. The injury of the dicamba is greater than 2,4-D, and the V5 stage is more susceptible to both herbicides. The greatest reductions in soybean yield follow the drift of dicamba in R2 and 2,4-D in V5. The physiological quality seeds of the soybean is reduced by dicamba and 2,4-D drift at both the V5 and R2 stages of the soybean. Soybean is highly sensitive to low rates of 2,4-D and dicamba at the vegetative or reproductive growth stages. Dicamba causes greater negative effects than 2,4-D on soybean. The low rate of 2,4-D and dicamba reduce germination and vigor seed on soybean offspring.

title: Micro-mechanical numerical analyses on the effect of stress state on ductile damage under dynamic loading conditions

description: Abstract The paper deals with the effect of stress state on the dynamic damage behavior of ductile materials. The rate- and temperature-dependent continuum damage model has been enhanced to take into account the influence of the stress triaxiality and the Lode parameter on damage condition and on rate equations of damage strains. Different branches of these criteria depending on the current stress state are considered based on different damage and failure processes on the micro-level. To get more insight in the dynamic damage and fracture processes micro-mechanical behavior of void-containing representative volume elements have been analyzed numerically. These three-dimensional numerical simulations based on different dynamic loading conditions take into account a wide range of stress states in tension, shear and compression domains. Based on the numerical results general trends of dynamic damage and failure behavior can be shown and stress-state-dependent equations for damage criteria and for the formation of damage strains can be proposed.

title: Branches of the aortic arch and thoracic aorta of the sloth (Bradypus variegatus)

description: ABSTRACT Sloths are arboreal mammals, very specific, regarding their habits and morphology. This condition makes them even more vulnerable to environmental impacts. In order to provide information to assist in the medical and surgical assistance to these Xenarthras, a study of the aortic arch and thoracic portion of the descending aorta was carried out with the purpose of identify its main branches. Ten animals of the Bradypus variegatus species were used. One female and three males were submitted to dissection, where measurements of vessel diameter and length were obtained, while three females and three males were submitted to the digital contrast x-ray technique. There was a uniform syntopy of the arch, as well as of the descending portion of the aorta in the thorax. However, the topography differs considerably. Based on the branches, regardless of gender, a greater variation was observed in those originating from the arch, and those that emerge from the thoracic aorta and irrigate medial structures and the right antimere of the thorax. Greater values were obtained for the diameter of the arteries in the female than in the males and corresponding values for the length of the thoracic aorta in both. All this variation is possibly related to the adaptive processes of Bradipodidae over time.
