To design connections between timber parts with metal dowels (nails or bolts), two phenomena must be considered: bending of the metal dowel and the embedment strength in the wood. The Brazilian Standard ABNT NBR 7190:1997 proposes the methods used in the laboratory tests to determine the embedment strength with the metal dowell and, in the absence of testing, specifies relations to calculate the embedment strength from the compression strength. The aim of this research was to compare the embedment strength values obtained by experimental tests and calculated by the relationships established by the Brazilian Standard ABNT NBR 7190:1997. By the results of the hypothesis tests, it was possible to conclude that the estimate of the embedment strength parallel to the grain proposed by the Brazilian standard ABNT NBR 7190:1997, establishing equivalence with the strength compression results in the same direction, must be effective to the wood species Pinus taeda L., however, the same was not found in the perpendicular direction with respect to the grain, possibly explained by the alpha(e) values in the equation to calculed fe(90)

The main feature of pulmonary emphysema is airflow obstruction resulting from the destruction of the alveolar walls distal to the terminal bronchioles. Existing clinical approaches have improved and extended the quality of life of emphysema patients. However, no treatment currently exists that can change the disease course and cure the patient. The different therapeutic approaches that are available aim to increase survival and/or enhance the quality of life of emphysema patients. In this context, cell therapy is a promising therapeutic approach with great potential for degenerative pulmonary diseases. In this protocol proposition, all patients will be submitted to laboratory tests, such as evaluation of heart and lung function and routine examinations. Stem cells will be harvested by means of 10 punctures on each anterior iliac crest, collecting a total volume of 200 mL bone marrow. After preparation, separation, counting and labeling (optional) of the mononuclear cells, the patients will receive an intravenous infusion from the pool of Bone Marrow Mononuclear Cells (BMMC). This article proposes a rational and safe clinical cellular therapy protocol which has the potential for developing new projects and can serve as a methodological reference for formulating clinical application protocols related to the use of cellular therapy in COPD. This study protocol was submitted and approved by the Brazilian National Committee of Ethics in Research (CONEP - Brazil) registration number 14764. It is also registered in ClinicalTrials.gov (NCT01110252). (c) 2013 Sociedade Portuguesa de Pneumologia. Published by Elsevier Espana, S.L. All rights reserved.

The aim of this study was to evaluate abdominal ultrasound images of dogs diagnosed with lymphoma. Seventy cases of dogs with lymphoma were analyzed. The animals selected were diagnosed with lymphoma which was confirmed by citology or histopathology. The most common sonographic alterations were abdominal lymphadenopathy (57.1%), hepatomegaly (54.2%) and splenomegaly (51.4%). Of the animals that had a cytology done of superficial lymph nodes, 82,8% showed diffuse sonographic changes in the liver, 54.5% had normal sonographic appearance in the spleen and enlargement of the medial iliac lymph nodes. Considering the results, we conclude that canine lymphoma is a complex disease and that it requires several laboratory tests for a correct diagnosis and prognosis.

Renal abscesses are rare in dogs and, although its pathogenesis is uncertain, may occur in diabetic patients with pyelonephritis, nephrolithiasis, kidney injuries or after abdominal surgery or kidney biopsy. Because of nonspecific clinical signs, laboratory tests associated with ultrasonography are important to confirm the diagnosis and treatment. Generally, kidney abscesses have sonographic aspects with different degrees of echogenicity such as hypo or hyperechoic, homogeneous or heterogeneous, and may or may not have thickened and hyperechoic walls, depending on its chronicity. Our objective was to report the use of ultrasound as a complementary method in the evaluation of disorders of the urinary tract, focusing on a case of renal abscess in a dog.
