Aorticopulmonary septal defect in a dog: case report

Na avaliação da dispneia pós-exercício em uma cadela de 10 meses de idade, não castrada e sem raça definida, foi detectado sopro sistólico leve grau II/VI. A comunicação entre a aorta ascendente e o tronco pulmonar, observada pela presença de fluxo contínuo logo abaixo das valvas semilunares, à ecoDopplercardiografia, foi confirmada pela cirurgia. Após o procedimento cirúrgico, a cadela apresentou boa condição clínica e ausência de dispneia mesmo ao exercício. Ressalta-se a importância do diagnóstico precoce e preciso para o sucesso terapêutico. Este é o primeiro relato brasileiro dessa rara doença e a única cirurgia, bem sucedida, descrita na literatura veterinária consultada.

Metastatic intraocular chondrosarcoma in a dog

Chondrosarcoma accounts for about 10% of all canine bone tumors and is the second most common primary bone tumor in dogs. In veterinary medicine, chondrosarcomas are classified as skeletal and extraskeletal. Extraskeletal chondrosarcomas are mesenchymal neoplasms of soft tissues and visceral organs that produce neoplastic chondrocytes in a fibrillary matrix. There is no involvement of bone or periosteal tissues in extraskeletal chondrosarcomas. The aim of this report is to describe the first case of a metastatic intraocular extraskeletal chondrosarcoma in a dog.

Effects of six carbohydrate sources on dog diet digestibility and post-prandial glucose and insulin response

The effects of six extruded diets with different starch sources (cassava flour, brewer's rice, corn, sorghum, peas or lentils) on dog total tract apparent digestibility and glycemic and insulinemic response were investigated. The experiment was carried out on thirty-six dogs with six dogs per diet in a completely randomized design. The diets containing brewer's rice and cassava flour presented the greatest digestibility of dry matter, organic matter and gross energy (p < 0.05), followed by corn and sorghum; pea and lentil diets had the lowest. Starch digestibility was greater than 98% in all diets and was greater for brewer's rice and cassava flour than for lentils and peas diets (p < 0.05). Dogs' immediate post-prandial glucose and insulin responses (AUC <= 30 min) were greater for brewer's rice, corn, and cassava flour diets (p < 0.05), and later meal responses (AUC >= 30 min) were greater for sorghum, lentil and pea diets (p < 0.05). Variations in diet digestibility and post-prandial response can be explained by differences in chemical composition of each starch source including fibre content and starch granule structure. The nutritional particularities of each starch ingredient can be explored through diet formulations designed to modulate glycemic response. However, more studies are required to support these.

Amylase utilization for the extrusion of dog diets

Effects of amylase addition on extruder parameters, cost of extrusion, kibble quality and digestibility of dog food were measured in two separate experiments. In experiment 1, 120 kilo-novo-alpha-amilase-unit (KNU)/kg of heat stable alpha-amylase produced by Bacillus licheniformis was added in liquid form during a preconditioning period. In experiment 23684 KNU/kg of heat stable alpha-amylase produced by Aspergillus oryzae was mixed with the ingredients before extrusion. The diets were processed in a single screw extruder and submitted to digestibility and on experiment 1 also to palatability tests. Digestibility was tested using 12 dogs, six per diet. Data were submitted to analysis of variance followed by F-test. Amylase addition altered extrusion parameters in both experiments (P<0.05), with higher output (kg of dry matter [DM]/h: 28% and 43% higher in experiments 1 and 2) and less electric energy consumption (kW to produce 100 kg DM: 22% and 29% lower in experiments 1 and 2). Kibble appearance and quality [density (g/L), cutting force (g), and starch gelatinization degree (%)] did not change with enzyme treatment (P>0.05). Likewise, enzyme addition did not change nutrient digestibility, fecal dry matter or food palatability (P<0.05). Taken together our results suggest that amylase promoted the breakdown of amylose chains, thereby reducing the dough viscosity and resistance inside the extruder which allowed for higher product flow and less electricity energy consumption without altering food quality.

Proteomic analysis of dog tears for potential cancer markers

The first reference map of the proteome of pooled normal dog tears was created using 2-dimensional polyacrylamide gel electrophoresis and the identity of a number of the major species determined using matrix-assisted laser desorption time of flight mass spectrometry (MALDI-TOF) and peptide mass fingerprint matching on protein sequence databases. In order to understand the changes in protein expression in the tear film of dogs with cancer, tears from such animals were similarly examined. A number of differences were found between the tears of healthy dogs and the dogs with cancer. Differences were found in levels of actin and albumin and in an unidentified protein which may be analogous to human lacryglobulin. These findings suggest that it may be possible to develop tear film analysis to provide a simple non-invasive test for the diagnosis and/or management of canine cancers. (C) 2007 Elsevier Ltd.

Foram analisados os resultados da fenestração ventral dos discos toracolombares em 29 cães agrupados segundo a raça, sexo, peso, idade, graus de déficits neurológicos, duração dos sinais, discos intervertebrais envolvidos, tempo para recuperação e porcentagem de sucesso. A raça Dachshund representou 55,18% (n = 16), cães sem raça definida, 13,8% (n = 4), Poodle e Basset Hound e Cocker Spaniel Inglês 6,89% cada (n = 6), e Pastor Alemão, Beagle e Pinscher, 3,45% cada (n = 3), sendo 51,72%, machos e 48,28%, fêmeas, com idade média de 68,03 meses. O grau de déficits neurológicos correspondeu a: 13,8% dos cães pertencentes ao GI (dor), 41,8% ao GII (paresia), 27,6% ao GIII (paraplegia com dor profunda presente) e 17,2% ao GIV (paraplegia com dor profunda ausente). Os sinais clínicos variaram em duração entre 2 e 60 dias, correspondendo às médias de 18,5 (GI), 12,3 (GII), 8,28 (GIII) e 4,2 dias (GIV). A porcentagem de discos intervertebrais acometidos foi: T10/11 (10,81%), T11/12 (24,33%), T12/13 (40,55%), T13/L1 (16,21%) e L1/2, L2/3 e L3/4, 2,7% cada. O tempo médio de recuperação, em dias, foi: 16 (GI), 19,1 (GII), 20,6 (GIII) e 30,6 (GIV), onde 100% dos animais dos grupos I, II e III recuperaram ambas as funções neurológicas e motoras. O grupo IV apresentou 80% de sucesso. Conclui-se que a fenestração ventral produz excelentes resultados pós-operatórios desde que bem selecionados os casos.

Orbital cellulitis associated with Toxocara canis in a dog

Reports of Toxocara canis ocular larva migrans are uncommon in animals, with only a few cases reported. Most reports involve larval migration into the retina and choroid, with parasitic invasion of the orbit reported only in experimental studies. This is the first clinical case of Toxocara canis infection in the retrobulbar region of a 10-year-old, cross-bred male dog presenting with unilateral orbital cellulitis. Ophthalmic signs included protrusion of the nictitating membrane, chemosis, exophthalmos and hypertropia. The parasite was diagnosed by histologic and parasitologic examination of orbital tissues, which were removed during enucleation.

INTRAOCULAR TRANSMISSIBLE VENEREAL TUMOR IN A DOG

Tumor venéreo transmissível (TVT) é uma neoplasia de células redondas que acomete a mucosa genital externa de cães, machos e fêmeas. A transmissão decorre da implantação de células tumorais durante o coito, brigas ou interações entre animais portadores e susceptíveis. Existem relatos referindo-se a localizações atípicas do TVT, mas metástases raramente ocorrem. O presente relato descreve um caso incomum de TVT, com acometimento intra-ocular e metástases nos linfonodos ingüinais, num cão Terrier Brasileiro, com seis anos de idade. O animal apresentava massas anormais de tecido no olho direito, extremidade do pênis e aumento de volume de linfonodos da região ingüinal. A histopatologia do globo ocular e as citologias da massa peniana e dos nódulos subcutâneos evidenciaram aspectos citológicos semelhantes, caracterizados por células redondas com núcleo grande e nucléolo proeminente localizado centralmente. O citoplasma apresentou-se pálido e com presença de vacúolos pequenos e arredondados. O diagnóstico de TVT com acometimento intra-ocular e metástases em linfonodos foi baseado nos achados clínicos, citológicos e histopatológicos.

Estimativa de safra para a cultura do milho através do filme infravermelho colorido

O sistema tradicional para estimativas de safra utiliza-se de relatórios técnicos de fontes diversas. A coleta de informações, se inicia antes da época do plantio e as estimativas são vendo ajustadas de acordo com o desenvolvimento das culturas. O trabalho em questão, pretende mostrar as possibilidades do filme infravermelho colorido na estimativa de safra para a cultura do milho. As informações quantitativas foram obtidas através da densitometria de transmissão. Os trabalhos foram conduzidos na Fazenda Experimental São Manuel da Faculdade de Ciências Agronômicas - Campus de Botucatu - UNESP. Os seis tratamentos consistiram em doses diferenciais de adubo, prevendo prováveis quedas em produção. A cultura foi fotografada com filme colorido (Kodak Ektachrome 64 ASA) e infravermelho colorido (Kodak Ektachrome Infrared Film) e a densidade ótica medida em um microdensitômetro de transmissão marca Weston, modelo 877 e abertura de 0,8 mm. Para avaliar a interação entre Produção e Densidade Ótica, utilizou-se das análises de correlação e regressão linear. A análise dos resultados permitiram as seguintes conclusões principais: a) Desde que se faça as necessárias calibrações, o filme infravermelho pode ser utilizado na estimativa de safra para a cultura do milho; b) A utilização do densitômetro de transmissão, para a interpretação quantitativa dos resultados, revelou-se importante sugerindo a aplicação do método em outros tipos de culturas.

A interculturalidade no cinema: um estudo da legendagem e da dublagem brasileiras em um filme francês contemporâneo

In this research we present a study of cultural aspects in dubbed and subtitled films. As a case study, we chose to compare the original French version of "Le fabuleux destin d'Amelie Poulain" with both the subtitled and the dubbed versions in Portuguese, with focus on the interaction between the French and the Brazilian cultures. First we considered that (i) the translation process interferes on the perception of cultural relationships; and that (ii) dubbing and subtitling are two methods of translation that result in distinct perceptions from the spectator. Then, we adopted the translation interpretative theory (Seleskovicth; Lederer, 2001; Deslile, 1980) as the general theoretical framework, since it emphasizes the extralinguistic equivalence on the translation process. Furthermore, we based this research on three analytical procedures, which are: the four-step translating operation, the contrastive perception and a translation's typology based on Vinay and Dalbernet's linguistic procedures (Srpová, 1991, 1995, 2004). We extracted forty-six culture-related elements from the film and identified those belonging to the French ethno-universe. Then, the elements were classified with respect to a theoretical typology, based on concepts found in the Ethnography of Communication and a general typology, based on five general thematic groups, defined by the corpus. The results showed that both Brazilian versions tend to preserve those culture-related elements by using lexical loan and literal translation. The visual context, in its association with the linguistic procedures in both Brazilian versions, was also observed as an important element to the comprehension of the culture-related elements as they are considered in the French culture. As a general observation, the perception of culture-related elements in the film seems effectively be oriented by the translation methods

Ultrastructural features in the epididymis of the dog (Canis familiaris, L.)

The ultrastructure of the epididymal duct of the dog is described in this paper. The epididymis was divided into three morphofunctional segments: initial, middle and terminal. The cellular population of the lining epithelium is formed from principal, apical, basal and clear cells. The peritubular stroma and the tubular interstitium surrounding the epithelium are also described. The outcome is compared to the description made in other species of mammals.
