ABSTRACT: Rice is the basis of diet for almost half of the world population, and its culture is one of the strategic agroindustrial production chains in the agribusiness environment, in both economic and social levels. Thus, the comparative analysis between the production chains of rice milled in Rio Grande do Sul (RS), Brazil, and Uruguay was mainly motivated by the interest in knowing the differences in the business environment and public policies that impact the competitiveness of this chain in both study regions. Therefore, the objective of this study was to assess the economic efficiency, competitiveness, and effects of public policies of the rice production chain of milled rice in RS (Brazil) relative to Uruguay. The data collected in this study are... |

ABSTRACT: The aim of this study was to evaluate the effect of osteoprogenitor cells derived from mesenchymal stem cells from adipose tissue (OC-AD-MSCs), and differentiated into osteoblasts, in the treatment of critical bone defects in dogs. Adipose tissue derived mesenchymal stem cells (AD-MSCs) were subjected to osteogenic differentiation for 21 days and used in the treatment of bone defects in dogs radius. Either three experimental groups were bone defects treated with OC-AD-MSCs (OC), defects filled with autogenous bone (Control- C +), or empty defects (Control- C -). Bone regeneration was assessed by radiology, densitometry, and histomorphometry. The area of new bone formation was higher in the OC group compared to the control group (C-) on... |

ABSTRACT: Gene expression of ErbB1 and ErbB2, and immunostaining of EGFR (Her1) and Her2 (c-erbB-2) were evaluated in this study to ascertain whether these receptors are involved in the evolution of canine premalignant and malignant prostatic lesions, as proliferative inflammatory atrophy (PIA) and prostatic carcinoma (PC). With regards to the intensity of EGFR immunostaining, there was no difference between normal prostatic tissue and tissues with PIA or PC. In relation to Her2 immunostaining, there were differences between normal prostatic tissue and those with PIA and PC, as also differences between prostates with PIA and PC. There was no correlation between EGFR and Her2 immunostaining. ErbB1 gene product was detected in two normal tissue samples, in... |

ABSTRACT: The carpus is a complex articulation, which is often involved in injuries in equine athletes. The objective of this study was to suggest a didactic approach for ultrasonography training for the examination of the carpal joint in horses. Ultrasonograhy examination was performed in a healthy 14-year-old horse. The images were compared with those of a dissected anatomic specimen of the carpal region of a senior horse and with those reported in the literature. Identifiable structures were as follows: (dorsal) tendon of the muscle extensor carpi radialis, tendon of the muscle extensor carpi obliquus, tendon of the muscle commom digital extensor, dorsal synovial outpouchings, joint capsule and fat cushion, (lateral) tendon of the muscle lateral digital... |

ABSTRACT: This study was designed to detect L. infantum infection in dogs and to evaluate the factors associated with canine visceral leishmaniasis in the maroon communities of Menino Jesus de Petimandeua and Itaboca in the municipality of Inhangapi, Pará, Brazil. Whole blood and intact skin samples were collected from 143 dogs, and a questionnaire was applied. L. infantum DNA was detected by polymerase chain reaction (PCR) using primers RV1 and RV2. Collection sites were georeferenced to obtain a spatial distribution of the residences visited and infected dogs. L. infantum DNA was detected in 8.4% (12/143) of the skin samples and in 1.4% (2/143) of the blood samples. On the risk map, three clusters were observed in Itaboca and one was observed in Menino... |

ABSTRACT: In a rural property of the Midwestern Minas Gerais, Brazil, three 2.5 to 3-year-old female bovines (7/8 Holstein x 1/8 Gir) weighing approximately 380kg died after showing brownish colored mucosa of conjunctiva and vaginal vestibule, gray-bluish tongue, dyspnea, sialorrhea, tympany, and progression to sternal decubitus and death. In the macroscopic evaluation of one of the bovines, dark (chocolate-colored) blood of difficult coagulation, and intensely cherry-red skeletal and cardiac musculature were observed. Beyond that were observed brownish lungs, kidneys, liver, and encephalon, and all the stomach compartments were dilated due to large amounts of gas. In addition, the carcass exhaled a nitrous odor. The diphenylamine test and the nitrate... |

ABSTRACT: Degradation that occursin agricultural soils causes compaction.Soil density (DS) analysis has been reported to be an unreliable method of measuring the extent of soil compaction, because it varies with the soil granulometric composition and organic matter (OM)content. However, soil relative density (DR) is a good indicator that facilitates the measurement of the degree of compaction and thus, soil comparison and management techniques. Quotient between the DS and its maximum density (Dsmax) gives the DR. This study aimed to assess the effect of the granulometric composition on the physical-hydrological properties of the high-silt containing soils,under no tillage. Samples from disturbed and undisturbed structures of 18 soils were collected from... |

ABSTRACT: This report aimed to describe a case of peripheral neuropathy in a copper-deficient goat, and highlights the clinical, and pathological features of the disease. The goat had low body score, hyporexia, alopecia, achromotrichia, left hindlimb protraction, paralysis with dragging of digit and difficulty to stand up and microcytic normochromic anemia. Copper concentration in serum was markedly lower (2.0µmol L-1) whereas the iron serum content was significantly increased (51.0µmol L-1). The main gross alteration was the reduction of the quadriceps vastus laterallis muscle volume. Histologically, there was atrophy of the quadriceps vastus laterallis muscle and presence of satellite cells, infiltration of lymphocytes, macrophages and replacement of the... |

ABSTRACT: The objective was to estimate the wood yield and essential oil content in three clones of eucalyptus that were planted in four contrasting arrangements and intercropped with sorghum. Eucalyptus clones MA2001 (Eucalyptus camaldulensis x E. tereticornis), A144 (Eucalyptus urophylla x E. grandis), and GG100 (Eucalyptus urophylla x E. grandis), were planted in single rows (10x2m), double rows (2x3+15m and 2x3+20m); and, triple rows (2x3x2+10m) in a randomized, complete block design experiment with four replicates. Our results demonstrated that planting spacing did not influence the essential oil yield or diameter at breast height in the clones. However, higher density plantings were shown to result in higher fresh weight of branches and leaves per... |

ABSTRACT: One of the biggest challenges for expansion of jabuticaba fruit tree cultivation is the high cost of seedlings due to to difficulties with vegetative propagation. Here, we aimed to evaluate graft survival in combinations of Plinia cauliflora and rootstocks of other species from the Myrtaceae family. The study was carried out at the Universidade Tecnológica Federal do Paraná - Campus Dois Vizinhos, Paraná State, Brazil. Eugenia uniflora L., E. involucrata DC, and P. cauliflora were used as rootstocks and were obtained as seeds. The 'whip-and- tongue' and cleft grafting techniques were tested for vegetative propagation. Grafted plants were cultivated in a greenhouse. The experimental design was a randomized complete block, in factorial 3×2... |
