Abstract: between 1986 and 1995, 72 cases of uremia were diagnosed from 1,623 (4.43%) dogs necropsied at the veterinary pathology lab of the "universidade federal de santa maria", rs, brazil. clinical signs of uremia were reported in 58 dogs (80.55%) and included mainly vomitus, anorexia, diarrhea and depression. extrarenal lesions of uremia were most evident, in decreasing order of frequency, in the following organ systems: alimentary, respiratory, cardiovascular, endocrine and skeletal. more frequently observed lesions were uremic gastropathy (79.16%) and pneumopathy (49.27%), and mural endocarditis of the left atrium associated with degenerative arteriopathy of the coronary vessels (34.72%). seventy (16.27%) out of 430 dogs with primary renal lesions had uremia. two (14.2%) out of 14 dogs with obstruction of the urinary flow developed post-renal uremia. no case of pre-renal uremia was diagnosed. the renal lesions which induced uremia in the dogs were glomerulonephritis, acute tubular nephrosis, interstitial nephritis, infarction, bilateral cystadenocarcinoma, and amyloidosis. the age of affected dogs varied from 2 months to 12 years. the acute and subacute renal lesions were more frequent in dogs up to 5 years and the chronic renal lesions were more frequent in dogs from 6 to 12 years of age.

Arquivos Brasileiros de Cardiologia , 2001,
Abstract: OBJECTIVE: To evaluate elastic properties of conduit arteries in asymptomatic patients who have severe chronic aortic regurgitation. METHODS: Twelve healthy volunteers aged 30±1 years (control group) and 14 asymptomatic patients with severe aortic regurgitation aged 29±2 years and left ventricular ejection fraction of 0.61±0.02 (radioisotope ventriculography) were studied. High-resolution ultrasonography was performed to measure the systolic and diastolic diameters of the common carotid artery. Simultaneous measurement of blood pressure enabled the calculation of arterial compliance and distensibility. RESULTS: No differences were observed between patients with aortic regurgitation and the control group concerning age, sex, body surface, and mean blood pressure. Pulse pressure was significantly higher in the aortic regurgitation group compared with that in the control group (78±3 versus 48±1mmHg, P<0.01). Arterial compliance and distensibility were significantly greater in the aortic regurgitation group compared with that in the control group (11.0±0.8 versus 8.1±0.7 10-10 N-1 m4, P=0.01 e and 39.3±2.6 versus 31.1±2.0 10-6 N-1 m2, P=0.02, respectively). CONCLUSION: Patients with chronic aortic regurgitation have increased arterial distensibility. Greater vascular compliance, to lessen the impact of systolic volume ejected into conduit arteries, represents a compensatory mechanism in left ventricular and arterial system coupling.
Silent Patent Ductus Arteriosus Aneurysm
Botta Aline Medeiros,Aquino Flávio,Pereira Carla,Fin Alberto
Arquivos Brasileiros de Cardiologia , 2002,
Abstract: Ductus arteriosus aneurysm, a rare and potentially fatal condition, has been reported as a complication after surgical ductus arteriosus closure. Its spontaneous appearance as a septic complication, which was common in the presurgical and preantibiotic era, has been rarely reported in the contemporary literature. Persistence of silent ductus arteriosus in healthy children and adults is a frequent condition that currently has an increasing diagnostic possibility due to the availability of more accurate investigative methods, especially echocardiography. We report the case of a 1-year-old child, in whom no previous heart disease was known, who developed a giant aneurysm of the ductus arteriosus during a staphylococcal infection. This complication appeared after craniotomy for emptying an accidental subdural hematoma. This report associates the persistence of ductus arteriosus with a complication considered rare, which has a rapidly fatal evolution.
A crise de paradigmas na ciência e as novas perspectivas para a enfermagem
Santos, Quintila Garcia;Azevedo, Dulcian Medeiros de;Costa, Roberta Kaliny de Sousa;Medeiros, Flávio Pereira de;
Escola Anna Nery , 2011, DOI: 10.1590/S1414-81452011000400024
Abstract: the paradigm is understood as a pattern to be followed, and includes the set of beliefs, values, techniques and shared theories and is influenced by cultural, political, economic and social laws. the objective was to conduct an analysis about the paradigmatic crisis of scientific knowledge and its implications in nursing, providing an overview of the development of a research in this area. the need for new guiding principles of scientific practice is urgently needed, which are emerging in ethics, environmental sustainability, interdisciplinary, appreciation of complexity, and respect for subjectivity. for nursing to become stronger as a science, profession and social practice is essential to use the tools available in promoting socio-political actions that point to a higher quality of life of society. the work process in health and its paradigms require from the nurse clarity of its limited scope, intervention, and ability to build new knowledge, promoting innovation in the health production.
Effective properties evaluation for smart composite materials
Medeiros, Ricardo de;Moreno, Mariano E.;Marques, Flávio D.;Tita, Volnei;
Journal of the Brazilian Society of Mechanical Sciences and Engineering , 2012, DOI: 10.1590/S1678-58782012000500004
Abstract: the purpose of this article is to present a method which consists in the development of unit cell numerical models for smart composite materials with piezoelectric fibers made of pzt embedded in a non-piezoelectric matrix (epoxy resin). this method evaluates a globally homogeneous medium equivalent to the original composite, using a representative volume element (rve). the suitable boundary conditions allow the simulation of all modes of the overall deformation arising from any arbitrary combination of mechanical and electrical loading. in the first instance, the unit cell is applied to predict the effective material coefficients of the transversely isotropic piezoelectric composite with circular cross section fibers. the numerical results are compared to other methods reported in the literature and also to results previously published, in order to evaluate the method proposal. in the second step, the method is applied to calculate the equivalent properties for smart composite materials with square cross section fibers. results of comparison between different combinations of circular and square fiber geometries, observing the influence of the boundary conditions and arrangements are presented.

Abstract: an experiment on gentamicin toxicosis was carried out in 11 dogs. ten dogs received 10 mg/kg intramuscularly 3 times a day for 14 days and another dog the same dosage for 10 days. all dogs were euthanatized and necropsied at the 11th, 15th-19th, 21th, 27th, and 37th day of the experiment. main clinical signs were: loss of appetite, apathy, polyuria, polydpsia, diarrhea, vomit and oliguria. laboratory findings included enzymuria, cylindruria, azotemia and isosthenuria. gross lesions were restricted to the kidneys, these were pallid, swollen and soft. two dogs developed mild perirenal edema. histologically, tubular necrosis, restricted to the proximal convoluted tubules, was observed in the kidneys of 10 dogs. in the kidneys of all dogs there was regeneration of epithelial cells of those tubules; this change occurred mainly in the external cortex, varied from minimal to marked, and was associated to marked tubule dilation. at the 37th day of the experrment, the kidneys have their normal morphology restored. neither glomerular lesions nor extrarenal lesions related to uremia were observed. it is concluded that gentamicin was toxic to dogs when administered in the dosis and frequency stated above and induced acute renal tubular necrosis with subsequent variable degrees of regeneration.

Abstract: three assays were carried out to determine methionine + cystine requirement and the digestible methionine + cystine: digestible lysine ratio of males broilers, avian farms, from 1 to 20, 24 to 38 and 44 to 56 days of age. each experiment was a completely randomized design with five levels of methionine + cystine, six replications and 20 birds per pen from 1 to 20 and 24 to 38 and 16 birds per pen from 44 to 56 day of age, respectively. the digestible methionine + cystine levels were 0.731-0.916% (in increments of 0.046); 0.712-0.881% (in increments of 0.042) and 0.631-0.781% (in increments of 0.037) for 1 to 20, 24 to 38 and 44 to 56 days of age, respectively. feed intake, weight gain, feed conversion and carcass quality were evaluated. there were linear positive and quadratic effects of the methionine + cystine levels on body weight gain and feed conversion, respectively, in the 1 to 20 days phase. using the broken line model, the requirement of digestible methionine + cystine (total) and the ratio of digestible methionine + cystine:digestible lysine for the 1 to 20 days phase was 0.808 (0.907% total) and 70%, respectively, according to the results of feed conversion. for the phase 24 to 38 days, weight gain, feed conversion and absolute leg quarter weight responded quadratically to increasing levels of digestible methionine + cystine. using the broken line model, the requirement of digestible methionine + cystine (total) and the ratio of digestible methionine + cystine:digestible lysine for the 24-38 days phase were 0.767 (0.844% total) and 72%, respectively, according to the results of body weight gain. the absence of a significant response for body weight gain and feed conversion in the third phase (44-56 days) demonstrates that the lowest level of methionine + cystine met the birds requirement. nevertheless, according to the best biological response the digestible (total) methionine + cystine were 0.668% (0.738% total) and 71%, respectively. methionine + cystin
